Description

BACKGROUND

Field

The disclosure relates to an electronic device and an operation method of the electronic device and to an electronic device supporting a non-terrestrial network.

Description of Related Art

In order to meet the increasing demand for wireless data traffic following the commercialization of the 4G communication system, efforts are being made to develop an improved 5G communication system or pre-5G communication system. For this reason, the 5G communication system or pre-5G communication system is called a beyond-4G network communication system or a post-LTE system. In order to attain high data rates, the 5G communication system is being considered to be implemented in ultra-high frequency (mmWave) bands (e.g., bands of 6 GHz or more) in addition to the bands (bands below 6 GHz) used in LTE. In the 5G communication system, beamforming, massive MIMO, full-dimension MIMO (FD-MIMO), array antenna, analog beamforming, and large scale antenna technologies are being discussed.

Recently, the provision of communication services using entities, which are not fixed on the ground, as well as base stations fixed on the ground, has been considered in the 5th generation communication system. According to an embodiment, the 5th generation communication system is considering the implementation of cellular communication using satellites. An electronic device may perform cellular communication using satellites when it is difficult to connect with a base station. Cellular communication using satellites may realize wider coverage than cellular communication using base stations due to the characteristics of satellites moving in Earth's orbit. Cellular communication using satellites is attracting attention in terms of reducing shadow areas where communication services are not available.

However, cellular communication using satellites has lower transmission and/or reception rates than cellular communication using base stations, so it may be used in providing limited services (e.g., a short message service (SMS) or voice calls).

An electronic device may attempt to discover a non-terrestrial network that performs data communication via satellites. The electronic device may attempt to connect to the discovered non-terrestrial network and, when the connection is completed, transmit and/or receive data via the satellites.

If there is a long distance between the electronic device and the satellite, path loss on the data transmission or reception path between the electronic device and the satellite may increase, and the time it takes for the electronic device to transmit or receive data may increase.

Furthermore, since the strength of a signal output from the electronic device is limited, the transmission data rate of the electronic device may be lowered. Therefore, communication services through non-terrestrial networks may be used within a limited scope. According to an example, a non-terrestrial network providing communication services using satellites may provide only specific services (e.g., a short messaging service (SMS) and a multimedia messaging service (MMS)) and may not provide other services (e.g., transmission and/or reception of user data).

The electronic device may transmit a signal requesting a specific service (e.g., transmission of user data) (e.g., requesting establishment of a packet data unit (PDU) session for user data transmission) to a network through a satellite. If the network is unable to provide the specific service, a reject message may be transmitted to the electronic device via the satellite in response to the request signal. It may take a long time for the electronic device to receive the reject message due to the relatively long distance between the electronic device and the satellite, and unnecessary power consumption and/or delay time may occur until the reject message is received.

SUMMARY

An electronic device according to an embodiment may include a communication circuit configured to support cellular communication through a terrestrial network and a non-terrestrial network. The electronic device may include a memory configured to store mapping data in which identification information of the non-terrestrial network and services supported by the non-terrestrial network are mapped. The electronic device may include a communication processor. The communication processor may identify, while connecting to a network through a node, whether the network including the node is the non-terrestrial network, based on system information received from the node. The communication processor may identify, based on the network being the non-terrestrial network, services supported by the network, based on the mapping data. The communication processor may prohibit transmission of a request message for establishment of a packet data unit (PDU) session for a service, which is not supported by the network, to the network.

A method of operating an electronic device according to an example embodiment may include identifying, while connecting to a network through a node, whether the network including the node is a non-terrestrial network, based on system information received from the node. The method may include identifying, based on the network being the non-terrestrial network, services supported by the network, based on mapping data in which identification information of the non-terrestrial network and services supported by the non-terrestrial network are mapped. The method may prohibit transmission of a request message for establishment of a packet data unit (PDU) session for a service, which is not supported by the network, to the network.

An electronic device and a method of operating the electronic device according to an embodiment may identify services supported by a non-terrestrial network and prohibit a request message for establishing a PDU session for a service that is not supported by the non-terrestrial network from being transmitting, to a network. Therefore, the electronic device may not transmit a message requesting the establishment of a PDU session for a service, which is not supported by the non-terrestrial network, to the network, thereby reducing unnecessary consumption of resources or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session for a service, which is not supported by the non-terrestrial network, is transmitted.

An electronic device and method of operating the electronic device according to an embodiment may receive a user equipment (UE) capability request message from a network and transmit, to the network, UE capability information excluding information that is not related to the network. The electronic device may reduce the amount of UE capability information by excluding information that is not related to the network, so that the electronic device may reduce the time (or delay time) required to transmit UE capability information.

The effects obtainable from the disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art to which the disclosure pertains from the description below.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, loss coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or a round trip of Ims or less) for implementing URLLC.

According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

In an embodiment, the external electronic device 104 may include an internet-of-things (IOT) device. The server 108 may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199.

FIG. 2 is a block diagram 200 of an electronic device 101 for supporting legacy network communication and 5G network communication according to certain embodiments. Referring to FIG. 2, the electronic device 101 may include a first communication processor (e.g., including processing circuitry) 212, a second communication processor (e.g., including processing circuitry) 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module 242, a second antenna module 244, and an antenna 248. The electronic device 101 may further include the processor 120 and the memory 130. The network 199 may include a first network 292 and a second network 294. According to an embodiment, the electronic device 101 may further include at least one component among the components illustrated in FIG. 1, and the network 199 may further include at least one other network. According to an embodiment, the first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may be included as at least a part of the wireless communication module 192. According to an embodiment, the fourth RFIC 228 may be omitted or may be included as a part of the third RFIC 226.

The first communication processor 212 may include various processing circuitry (as used herein, including the claims, the term “processor”, “communication processor”, etc., may include various processing circuitry, including at least one processor, wherein one or more processors of the at least one processor may be configured to perform the various functions described herein) and establish a communication channel of a band to be used for wireless communication with the first network 292, and may support legacy network communication via the established communication channel. According to certain embodiments, the first network may be a legacy network including 2G, 3G, 4G, or long term evolution (LTE) network. The second communication processor 214 may include various processing circuitry and establish a communication channel corresponding to a designated band (e.g., approximately 6 GHz to 60 GHz) among bands to be used for wireless communication with the second network 294, and may support 5G network communication via the established channel. According to certain embodiments, the second network 294 may be a 5G network defined in 3GPP. Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another designated band (e.g., lower than 6 GHz) among bands to be used for wireless communication with the second network 294, and may support 5G network communication via the established channel. According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to certain embodiments, the first communication processor 212 or the second communication processor 214 may be implemented in a single chip or a single package, together with the processor 120, the sub-processor 123, or the communication module 190.

In the case of transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal in a range of approximately 700 MHz to 3 GHz used for the first network 292 (e.g., a legacy network). In the case of reception, an RF signal is obtained from the first network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242), and may be preprocessed via an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the preprocessed RF signal to a baseband signal so that the base band signal is processed by the first communication processor 212.

In the case of transmission, the second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., lower than 6 GHz) used for the second network 294 (e.g., 5G network). In the case of reception, a 5G Sub6 RF signal is obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244), and may preprocessed by an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the baseband signal is processed by a corresponding communication processor from among the first communication processor 212 or the second communication processor 214.

The third RFIC 226 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, a 5G Above6 RF signal) of a 5G Above6 band (e.g., approximately 6 GHz to 60 GHz) to be used for the second network 294 (e.g., 5G network). In the case of reception, a 5G Above6 RF signal is obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., the antenna 248), and may be preprocessed by the third RFFE 236. The third RFIC 226 may convert the preprocessed 5G Above6 RF signal to a baseband signal so that the base band signal is processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be implemented as a part of the third RFIC 226.

According to an embodiment, the electronic device 101 may include the fourth RFIC 228, separately from or as a part of the third RFIC 226. In this instance, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, an IF signal) in an intermediate frequency band (e.g., approximately 9 GHz to 11 GHz), and may transfer the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal to a 5G Above6 RF signal. In the case of reception, a 5G Above6 RF signal is received from the second network 294 (e.g., a 5G network) via an antenna (e.g., the antenna 248), and may be converted into an IF signal by the third RFFE 226. The fourth RFIC 228 may convert the IF signal to a baseband signal so that the base band signal is processed by the second communication processor 214.

According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as a single chip or at least a part of the single package. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as a single chip or at least a part of the single package. According to an embodiment, at least one antenna module of the first antenna module 242 or the second antenna module 244 may be omitted, or may be combined with another antenna module so as to process RF signals in a plurality of bands.

According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed in the same substrate, and may form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed in a first substrate (e.g., main PCB). In this instance, the third RFIC 226 is disposed in a part (e.g., a lower part) of the second substrate (e.g., a sub PCB) separate from the first substrate and the antenna 248 is disposed on another part (e.g., an upper part), so that the third antenna module 246 is formed. By disposing the third RFIC 226 and the antenna 248 in the same substrate, the length of a transmission line therebetween may be reduced. For example, this may reduce a loss (e.g., attenuation) of a signal in a high-frequency band (e.g., approximate 6 GHz to 60 GHz) used for 5G network communication, the loss being caused by a transmission line. Accordingly, the electronic device 101 may improve the quality or speed of communication with the second network 294 (e.g., 5G network).

According to an embodiment, the antenna 248 may be implemented as an antenna array including a plurality of antenna elements which may be used for beamforming. In this instance, the third RFIC 226 may be, for example, a part of the third RFFE 236, and may include a plurality of phase shifters 238 corresponding to a plurality of antenna elements. In the case of transmission, each of the plurality of phase shifters 238 may shift the phase of a 5G Above6RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station of a 5G network) via a corresponding antenna element. In the case of reception, each of the plurality of phase shifters 238 may shift the phase of the 5G Above6 RF signal received from the outside via a corresponding antenna element into the same or substantially the same phase. This may enable transmission or reception via beamforming between the electronic device 101 and the outside.

The second network 294 (e.g., 5G network) may operate independently (e.g., Stand-Along (SA)) from the first network 292 (e.g., a legacy network), or may operate by being connected thereto (e.g., Non-Stand Alone (NSA)). For example, in the 5G network, only an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) may exist, and a core network (e.g., next generation core (NGC)) may not exist. In this instance, the electronic device 101 may access an access network of the 5G network, and may access an external network (e.g., the Internet) under the control of the core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with the legacy network or protocol information (e.g., New Radio (NR) protocol information) for communication with the 5G network may be stored in the memory 230, and may be accessed by another component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

Referring to FIGS. 4A, 4B and 4C, network environments 100A, 100B and 100C may include at least one of a legacy network and a 5G network. The legacy network may include, for example, a 4G or LTE eNB 450 (for example, an eNodeB (eNB)) of the 3GPP standard supporting radio access with the electronic device 101 and an evolved packet core (EPC) 451 for managing 4G communication. The 5G network may include, for example, a new radio (NR) gNB 450 (for example, a gNodeB (gNB)) supporting radio access with the electronic device 101 and a 5th generation core (5GC) 452 for managing 5G communication of th electronic device 101.

According to certain embodiments, the electronic device 101 may transmit and receive a control message and user data through legacy communication and/or 5G communication. The control message may include, for example, a control message related to at least one of security control of the electronic device 101, bearer setup, authentication, registration, or mobility management. The user data may be, for example, user data other than a control message transmitted and received between the electronic device 101 and a core network 430 (for example, the EPC 442).

Referring to FIG. 4A, the electronic device 101 according to an embodiment may transmit and receive at least one of a control message or user data to and from at least some of the 5G network (for example, the NR gNB 450 and the 5GC 452) using at least some of the legacy network (for example, the LTE eNB 440 and the EPC 442).

According to certain embodiments, the network environment 100A may include a network environment for providing wireless communication dual connectivity (multi-radio access technology (RAT) dual connectivity (MR-DC)) to the LTE eNB 440 and the NR gNB 450 and transmitting and receiving a control message to and from the electronic device 101 through one core network 430 of the EPC 442 or the 5GC 452.

According to certain embodiments, one of the MR-DC environment, the LTE eNB 440 or the NR gNB 450 may operate as a master node (MN) 410, and the other may operate as a secondary node (SN) 420. The MN 410 may be connected to the core network 430 and transmit and receive a control message.

For example, a control message may be transmitted and received through the LTE eNB 440 and the EPC 442, and user data may be transmitted and received through the LTE eNB 450 and the NR gNB 450.

Referring to FIG. 4B, according to certain embodiments, the 5G network may independently transmit and receive a control message and user data to and from the electronic device 101.

Referring to FIG. 4C, the legacy network and the 5G network according to certain embodiments may independently provide data transmission and reception.

According to certain embodiments, the EPC 442 or the 5GC 452 may interwork and manage communication of the electronic device 101. For example, movement information of the electronic device 101 may be transmitted and received through an interface between the EPC 442 and the 5GC 452.

FIG. 5 is a diagram illustrating an electronic device and a cellular network according to an embodiment.

An electronic device (e.g., the electronic device 101 in FIG. 1) may transmit and/or receive data through a terrestrial network and/or a non-terrestrial network.

The terrestrial network may refer to a network capable of providing data communication through a first node (e.g., the NR base station 450 in FIG. 4B or LTE base station 440 in FIG. 4C) 510 fixed to the ground.

The non-terrestrial network may, for example, and without limitation, refer to a network capable of providing data communication through a satellite 520 that is not fixed to the ground.

The first node 510 may refer, for example, to a base station that supports first cellular communication or second cellular communication. The first cellular communication is any one of various cellular communication schemes supported by an electronic device (e.g., the electronic device 101 in FIG. 1) and may be, for example, a communication scheme on the second cellular network 294 in FIG. 2. For example, the first cellular communication may be a communication scheme using a 5th generation mobile communication scheme (e.g., new radio (NR)). The second cellular communication is any one of various cellular communication schemes supported by the electronic device 101, and may be, for example, a communication scheme on the first cellular network 292 in FIG. 2. For example, the second cellular communication may be a communication scheme using a 4th generation mobile communication scheme (e.g., long-term evolution (LTE)).

The first node 510 may transmit or receive signals in frequency bands supported by first cellular communication or second cellular communication. In the case where the electronic device 101 is connected to a terrestrial network through the first node 510, the electronic device 101 may perform data communication using a signal in the frequency band supported by the first node 510.

The satellite 520 may function as a base station supporting the first cellular communication or the second cellular communication. The satellite 520 may transmit or receive signals in frequency bands supported by the first cellular communication or the second cellular communication. In the case where the electronic device 101 is connected to a non-terrestrial network through the satellite 520, the electronic device 101 may perform data communication using signals in the frequency band supported by the satellite 520.

The electronic device 101 may be connected to the non-terrestrial network through the satellite 520, thereby performing various services.

The distance between the electronic device 101 and the satellite 520 may be greater than the distance between the electronic device 101 and the first node 510. If the electronic device 101 and the satellite 520 has a long distance therebetween, path loss on the data transmission or reception path between the electronic device 101 and the satellite may increase, and the time it takes for the electronic device 101 to transmit or receive data may increase. Furthermore, since the strength of a signal output from the electronic device 101 is limited, the transmission data rate of the electronic device 101 may be lowered. Therefore, communication services using the satellite 520 may be used within a limited scope. According to an example, a non-terrestrial network providing communication services using the satellite 520 may provide only specific services (e.g., a short messaging service (SMS) and a multimedia messaging service (MMS)) and may not provide other services (e.g., transmission and/or reception of user data).

The electronic device 101 may transmit a signal requesting a specific service (e.g., transmission of user data) (e.g., requesting establishment of a packet data unit (PDU) session for user data transmission) to a network through the satellite 520. If the network is unable to provide the specific service, a reject message may be transmitted to the electronic device 101 via the satellite 520 in response to the request signal. It may take a relatively long time for the electronic device 101 to receive the reject message due to the relatively long distance between the electronic device 101 and the satellite 520, and unnecessary power consumption and/or delay time may occur until the reject message is received.

Hereinafter, an embodiment in which the electronic device 101 prohibits (or refrains from) transmitting unnecessary signals and/or data to the non-terrestrial network, avoiding (or reducing) unnecessary resource consumption, will be described in greater detail with reference to the following figures.

FIG. 6 is a block diagram of an electronic device according to an embodiment.

Referring to FIG. 6, an electronic device (e.g., the electronic device 101 in FIG. 1) according to various embodiments of the disclosure may include a communication circuit (e.g., the wireless communication module 192 in FIG. 1) 610, a communication processor (e.g., the processor 120 in FIG. 1 or the first communication processor 212 and/or the second communication processor 214 in FIG. 2) (e.g., including various processing circuitry) 620, and/or a memory (e.g., the memory 130 in FIG. 1) 630.

The communication circuit 610 may include, for example, a communication circuit that supports first cellular communication and/or second cellular communication, and may provide the electronic device 101 with communication with an external electronic device (e.g., the electronic device 104 in FIG. 1) through the first cellular communication and/or the second cellular communication. The first cellular communication is any one of various cellular communication schemes supported by the electronic device (e.g., the electronic device 101 in FIG. 1) and may be, for example, a communication scheme on the second cellular network 294 in FIG. 2. For example, the first cellular communication may be a communication scheme using a 5th generation mobile communication scheme (e.g., new radio (NR)). The second cellular communication is any one of various cellular communication schemes supported by the electronic device 101, and may be, for example, a communication scheme on the first cellular network 292 in FIG. 2. For example, the second cellular communication may be a communication scheme using a 4th generation mobile communication scheme (e.g., long-term evolution (LTE)).

The communication processor 620 may include various processing circuitry (as used herein, including the claims, the term “processor”, “communication processor”, etc., may include various processing circuitry, including at least one processor, wherein one or more processors of the at least one processor may be configured to perform the various functions described herein) and be operatively connected to the communication circuit 610. The communication processor 620 may control elements of the electronic device 101. For example, the communication processor 620 may control the elements of the electronic device 101 according to one or more instructions stored in the memory (e.g., the memory 130 in FIG. 1).

The communication processor 620 may control the communication circuit 610 to transmit and/or receive data through a terrestrial network and/or a non-terrestrial network.

The terrestrial network may refer to a network capable of providing data communication through a first node (e.g., the first node 510 in FIG. 5) fixed to the ground.

The non-terrestrial network may refer to a network capable of providing data communication through a node (e.g., the satellite 520 in FIG. 5) that is not fixed to the ground.

The communication processor 620 may control the communication circuit 610 to perform searching for a network for connection with the network. If the search for the network is successful, the communication processor 620 may perform a series of procedures to connect to the searched network.

The communication processor 620 may receive system information transmitted or broadcast by a node (e.g., the satellite 520 in FIG. 5) included in the network (e.g., the non-terrestrial network) while performing the network search.

The communication processor 620 may identify whether the searched network is a non-terrestrial network, based on the received system information.

The system information broadcast by node 520 may include a variety of information. According to an example, the system information may include SIB 1 defined in 3GPP TS. 36.331 v15.6. SIB 1 may include identification information (e.g., mobile country code (MCC) and public land mobile network (PLMN)) of the network including the node 520, information required to perform access (or random access (RA)) to the node 520, and/or information indicating that the network is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

If it is identified that the network identification information included in the system information transmitted or broadcast by the node 520 is specified identification information (e.g., identification information of a non-terrestrial network), the communication processor 620 may identify that the searched network is a non-terrestrial network. According to an example, MCC of a non-terrestrial network may start with 9. If it is identified that MCC of the network included in the system information transmitted or broadcast by the node 520 begins with 9, the communication processor 620 may identify that the searched network is a non-terrestrial network.

The communication processor 620 may identify that the searched network is a non-terrestrial network, based on information indicating that the network included in the system information transmitted or broadcast by the node 520 is a non-terrestrial network. According to an example, the communication processor 620 may identify that the searched network is a non-terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as not barred. The communication processor 620 may identify that the searched network is a terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as barred or that the cellBarredNTN IE is not included in the system information.

According to an example, the system information may include SIB 19 defined in 3GPP TS. 38.304. SIB 19 may include system information transmitted or broadcast when the network including the node 520 is a non-terrestrial network and may include information related to the non-terrestrial network (e.g., altitude information of the node 520 and movement speed information of the node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by the node 520 is SIB 19, the communication processor 620 may identify that the searched network is a non-terrestrial network.

The communication processor 620 may identify that the searched network is a non-terrestrial network and identify services supported (or services not supported) by the searched network, based on mapping data stored in the memory 630.

The mapping data may be data in which the identification information of the non-terrestrial network and information of services supported by the non-terrestrial network are mapped and stored. According to an example, the mapping data may be implemented as shown in Table 1 below and stored in the memory 630.

Referring to Table 1, the mapping data may be data obtained by mapping a specific network to whether services are supported. For example, the communication processor 620, based on the mapping data, may identify that the first network (991-01) supports the SMS service but does not support the MMS service, user data transmission and/or reception service, and satellite PDU service. For example, the communication processor 620, based on the mapping data, may identify that the second network (992-02) supports the SMS service and MMS service but does not support the user data transmission and/or reception service and satellite PDU service. For example, the communication processor 620, based on the mapping data, may identify that the third network (993-03) supports the SMS service, MMS service, and user data transmission and/or reception service but does not support the satellite PDU service. For example, the communication processor 620, based on the mapping data, may identify that the fourth network (994-04) supports the SMS service, MMS service, and satellite PDU service but does not support the user data transmission and/or reception service. The satellite PDU service is a service for transmitting and/or receiving user data using a PDU capable of being used only by the non-terrestrial network, and may refer to a service for transmitting and/or receiving user data using a PDU incapable of being accessed through the terrestrial network.

The communication processor 620 may not transmit a request message for establishing a PDU session for a service, which is not supported by the network, to the network. The communication processor 620 may prohibit a request message for establishing a PDU session for a service, which is not supported by the network, from being transmitted to the network. The communication processor 620 may not transmit, to the network, a request message for establishing a PDU session for a service, which is not supported by the network, thereby preventing and/or reducing unnecessary resource consumption due to transmission of a request message for establishing a PDU session.

According to an example, the communication processor 620 may be connected to the network through first cellular communication. The first cellular communication may support the transmission or reception of SMS through a non-access stratum (NAS), and thus the first cellular communication may not require establishment of a separate PDU session for the SMS service.

The communication processor 620 may identify, based on the mapping data, that the network connected through the first cellular communication supports only the SMS service (e.g., the first network) and may not transmit a signal requesting establishment of a separate PDU session to the node 520. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to a network that does not support data transmission and/or reception through the PDU session.

According to an example, the communication processor 620 may be connected to the network through second cellular communication. The second cellular communication may require establishment of a PDU session for the transmission and reception of SMS.

The communication processor 620 may identify, based on the mapping data, that the network connected through the second cellular communication supports only the SMS service (e.g., the first network) and transmit a signal requesting establishment of a PDU session for the SMS service to the node 520. However, the communication processor 620 may not transmit, to the node 520, a signal requesting establishment of separate PDU sessions for services other than the SMS service. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to a network that does not support data transmission and/or reception through the PDU session.

The communication processor 620 may identify, based on the mapping data, that the network connected through the first cellular communication or the second cellular communication supports the SMS service and the MMS service but does not support the transmission or reception of user data (e.g., the second network) and transmit a signal requesting establishment of a PDU session for the MMS service to the node 520. However, the communication processor 620 may not transmit, to the node 520, a signal requesting establishment of separate PDU sessions for services (e.g., the user data transmission or reception service) other than the MMS service. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to a network that does not support the user data transmission and/or reception through the PDU session.

The communication processor 620 may identify, based on the mapping data, that the network connected through the first cellular communication or the second cellular communication supports the SMS service, MMS service, and transmission or reception of user data (e.g., the third network) and transmit, to the node 520, a signal requesting establishment of a PDU session for the MMS service and/or a signal requesting establishment of a PDU session for the user data transmission or reception service. The communication processor 620 may perform a series of procedures for establishing a PDU session for the user data transmission or reception service after transmitting the signal requesting the establishment of a PDU session for the user data transmission or reception service. The communication processor 620 may transmit data to the network or receive data from the network through the PDU session for the user data transmission or reception service.

However, the communication processor 620 may receive, from an application processor (e.g., the processor 120 in FIG. 1), a signal requesting to prohibit transmission and/or reception of user data by applications other than a specified application. The application processor 120 may specify in advance an application capable of performing the data transmission or reception through a non-terrestrial network, and the application processor 120 may prohibit applications other than the specified application from transmitting or receiving user data. According to an example, the application processor 120 may not transmit user data generated by applications other than the specified application to the communication processor 620. Alternatively, even if the application processor 120 transmits user data generated by applications other than the specified application to the communication processor 620, the application processor 120 may control the communication processor 620 to not transmit the user data through a PDU session for the user data transmission or reception service.

The communication processor 620 may identify, based on the mapping data, that the network connected through the first cellular communication or the second cellular communication supports the SMS service, MMS service, and transmission or reception of user data through a satellite PDU (e.g., the fourth network) and transmit a signal requesting establishment of a satellite PDU session to the node 520. The communication processor 620 may prohibit transmission of a signal requesting the establishment of a PDU session for transmitting or receiving user data. The communication processor 620 may transmit a signal requesting the establishment of a satellite PDU session and then perform a series of procedures for establishing the satellite PDU session. The communication processor 620 may transmit data to the network or receive data from the network through the satellite PDU session.

However, the communication processor 620 may receive, from the application processor (e.g., the processor 120 in FIG. 1), a signal requesting to prohibit transmission and/or reception of user data by applications other than the specified application. The application processor 120 may pre-specify an application capable of performing data transmission or reception through a non-terrestrial network, and the application processor 120 may prohibit applications other than the specified application from transmitting or receiving user data. According to an example, the application processor 120 may not transmit user data generated by applications other than the specified application to the communication processor 620. Alternatively, even if the application processor 120 transmits user data generated by applications other than the specified application to the communication processor 620, the application processor 120 may control the communication processor 620 to not transmit the user data through a satellite PDU session.

As described above, the electronic device 101 may not transmit a message requesting the establishment of a PDU session for a service, which is not supported by the non-terrestrial network, to the node 520, thereby reducing unnecessary consumption of resources or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session for a service, which is not supported by the non-terrestrial network, is transmitted.

In addition to prohibiting the establishment of a PDU session, the electronic device 101 may reduce the size of data included in the signal to be transmitted to the non-terrestrial network, thereby reducing delay time that occurs when the node 520 and the electronic device 101 have a long distance therebetween.

The communication processor 620 may receive a UE capability request message from the network during a registration process in the network or after the registration of the network.

After an RRC connection is established with the electronic device 101, the network may transmit a UE capability request message to the electronic device 101 when UE capability information is required. The UE capability information may refer to information indicating the performance of the electronic device 101 in relation to cellular communication of the electronic device 101. For example, the UE capability information may include information indicating a frequency band capable of being supported by the electronic device 101 or information indicating a combination of frequency bands capable of being supported by the electronic device 101. The combination of frequency bands capable of being supported by the electronic device 101 may refer to a combination of frequency bands in which the electronic device 101 is able to perform simultaneous transmission or reception of data. For example, if the electronic device 101 may simultaneously perform both transmission (or reception) of a signal through a first frequency band and transmission (or reception) of a signal through a second frequency band, the combination of frequency bands capable of being supported by the electronic device 101 may be the first frequency band and the second frequency band.

Upon receiving the UE capability request message from the network, the communication processor 620 may transmit UE capability information to the network through the node 520.

When transmitting the UE capability information, the communication processor 620 may transmit UE capability information excluding information that is not related to the network (or not including information that is not related to the network) to the network.

According to an example, in the case where the network is a non-terrestrial network, the network may not support communication schemes (e.g., carrier aggregation (CA), E-UTRA-NR dual connectivity (EN-DC), or multi-RAT dual connectivity (MR-DC)) that support transmission or reception of data through a plurality of frequency bands. If the network does not support transmission or reception of data through a plurality of frequency bands, the combination of frequency bands capable of being supported by the electronic device 101 may be unnecessary information for the network. Accordingly, the communication processor 620 may transmit UE capability information that does not include information indicating a combination of frequency bands supported by the electronic device 101 to the network, thereby reducing the time (or delay time) for transmission of the UE capability information.

According to an example, in the case where the network is a non-terrestrial network, the network may not support communication schemes (e.g., carrier aggregation (CA), E-UTRA-NR dual connectivity (EN-DC), or multi-RAT dual connectivity (MR-DC)) that support transmission or reception of data through a plurality of frequency bands. If the network does not support transmission or reception of data through a plurality of frequency bands, information indicating whether the electronic device 101 supports different generations of cellular communication schemes may be unnecessary information for the network. Accordingly, the communication processor 620 may transmit UE capability information that does not include information indicating whether the electronic device 101 supports different generations of cellular communication schemes to the network, thereby reducing the time (or delay time) for transmission of the UE capability information.

According to an example, in the case where the network is a non-terrestrial network, the network may not support communication schemes (e.g., MIMO (multi-input and multi-output)) that support transmission or reception of data using a plurality of antennas. If the network does not support transmission or reception of data through a plurality of frequency bands, information indicating whether the electronic device 101 supports communication schemes supporting the transmission or reception of data using a plurality of antennas may be unnecessary information for the network. Accordingly, the communication processor 620 may transmit UE capability information that does not include information indicating whether the electronic device 101 supports communication schemes supporting the transmission or reception of data using a plurality of antennas to the network, thereby reducing the time (or delay time) for transmission of the UE capability information.

In addition to the examples described above, the communication processor 620 may reduce the time (or delay time) for transmission of UE capability information by transmitting, to the network, UE capability information excluding information that is not related to the network.

According to an example, in the case where the network is a non-terrestrial network, the network may not support various configurations (e.g., conditional handover) of a specific frequency band (e.g., a specific frequency band (e.g., FR2-1 (24250 MHz to 52600 MHz) or FR2-2 (52600 MHz to 71000 MHz)) supporting time duplex divisional (TDD)). If the network does not support various configurations of a specific frequency band, information indicating whether the electronic device 101 supports various configurations of a specific frequency band may be unnecessary information for the network. Accordingly, the communication processor 620 may transmit UE capability information that does not include information indicating whether the electronic device 101 supports various configurations of a specific frequency band to the network, thereby reducing the time (or delay time) for transmission of the UE capability information.

The communication processor 620 may transmit, to the network, UE capability information excluding information that is not related to the network but including information that is related to the network, thereby reducing the time (or delay time) for transmission of the UE capability information.

According to an example, in the case where the network is a non-terrestrial network, the network may support a specific frequency band (e.g., FR1 (410 MHz to 7125 MHz) band supporting frequency divisional duplex (FDD)). If the network supports various configurations of a specific frequency band, information indicating whether the electronic device 101 supports various configurations of a specific frequency band may be necessary information for the network. Accordingly, the communication processor 620 may transmit UE capability information that includes information indicating whether the electronic device 101 supports various configurations of a specific frequency band to the network, thereby reducing the time (or delay time) for transmission of the UE capability information.

According to an example, the communication processor 620 may transmit, to the network, UE capability information including information expected to be required by the network. According to an example, if the electronic device 101 supports parallel measurement to measure the quality of signals in a plurality of frequency bands, the communication processor 620 may also transmit UE capability information including information related to the parallel measurement to the network.

The communication processor 620 may determine whether to perform a specified service, based on system information broadcast by a connected network (or node 520).

According to an example, the system information may include SIB 19 defined in 3GPP TS. 38.304. SIB 19 may include system information transmitted or broadcast when the network including the node 520 is a non-terrestrial network and may include information related to the non-terrestrial network (e.g., altitude information of the node 520 or movement speed information of the node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network.

The communication processor 620 may identify altitude information of the node 520 included in the system information transmitted or broadcast by the node 520 and determine whether to perform a specified service, based on whether the altitude of the node 520 is greater than or equal to a specified value (e.g., threshold).

The altitude information of the node 520 may include a field value included in the field of semiMajorAxis of EphemerisInfo IE of NTN-config, which is included in SIB 19. The communication processor 620 may determine the altitude of the node 520 using the field value and the method defined in TS 38.331 (e.g., Equation 1).

$\begin{array}{cc}\mathrm{Altitude}\mathrm{of}\mathrm{node}=6500000+\left(\mathrm{field}\mathrm{value}\right)*\left(4.249*{10}^{-3}\right)& \left[\mathrm{Equation}1\right]\end{array}$

The specified service may be a service that requires a low delay time. For example, the specified service may include voice calls or video calls. When the electronic device 101 performs a service requiring a low delay time, as the distance between the electronic device 101 and the node 520 increases, the quality of service may deteriorate or the service may not be performed. Accordingly, if the altitude of the node 520 is equal to or greater than (or exceeds) the specified value (threshold), the communication processor 620 may not perform the specified service or may stop performing the specified service. The specified value is a value related to the specified service and may be a value related to the maximum altitude of the node 520 capable of performing the specified service. The specified value may be a value pre-stored in the memory 630 or may be a value related to the altitude of the node 520.

If the altitude of the node 520 is equal to or less than (or below) the specified value (threshold), the communication processor 620 may perform the specified service or continue to perform the specified service.

While performing the specified service, the communication processor 620 may encode data related to the specified service using a codec that supports the lowest data rate. The communication processor 620 may reduce the size of data using a codec that supports the lowest data rate, thereby reducing the time (or delay time) required to transmit encoded data.

FIG. 7 is a diagram illustrating an embodiment in which an electronic device prohibits a request signal for establishing a PDU session according to an embodiment.

An electronic device (e.g., the electronic device 101 in FIG. 6) may transmit a registration request signal to a network 701 in operation 711.

The electronic device 101 may control the communication circuit 610 to search for the network 701 for connection to the network 701. If searching for the network 701 is successful, the electronic device 101 may perform a series of procedures to connect to the searched network 701.

The electronic device 101 may receive system information transmitted or broadcast by a node (e.g., the satellite 520 in FIG. 5) included in the network 701 (e.g., a non-terrestrial network) while performing searching for the network 701.

The electronic device 101 may identify whether the searched network 701 is a non-terrestrial network, based on the received system information.

The system information broadcast by the node 520 may include a variety of information. According to an example, the system information may include SIB 1 defined in 3GPP TS. 36.331 v15.6. SIB 1 may include identification information (e.g., mobile country code (MCC) and public land mobile network (PLMN)) of the network 701 including the node 520, information required to perform access (or random access (RA)) to the node 520, and/or information indicating that the network 701 is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

If it is identified that the identification information of the network 701 included in the system information transmitted or broadcast by the node 520 is specified identification information (e.g., identification information of a non-terrestrial network), the electronic device 101 may identify that the searched network 701 is a non-terrestrial network.

The electronic device 101 may identify that the searched network 701 is a non-terrestrial network, based on information indicating that the network 701 included in the system information transmitted or broadcast by the node 520 is a non-terrestrial network. According to an example, the electronic device 101 may identify that the searched network 701 is a non-terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as not barred. The electronic device 101 may identify that the searched network 701 is a terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as barred or that the cellBarredNTN IE is not included in the system information.

According to an example, the system information may include SIB 19 defined in 3GPP TS. 38.304. SIB 19 may include system information transmitted or broadcast when the network 701 including the node 520 is a non-terrestrial network and may include information related to the non-terrestrial network (e.g., altitude information of the node 520 and movement speed information of the node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by the node 520 is SIB 19, the electronic device 101 may identify that the searched network 701 is a non-terrestrial network.

The electronic device 101 may identify that the searched network 701 is a non-terrestrial network and identify services supported (or services not supported) by the searched network 701, based on mapping data stored in the memory 630.

The mapping data may be data in which the identification information of the non-terrestrial network and information of services supported by the non-terrestrial network are mapped and stored.

The electronic device 101 and the network 701 may perform a registration procedure for the electronic device 101 in operation 713.

The electronic device 101 may complete registration with respect to the network 701 through a series of operations including initial access to the node 520 included in the searched network 701 and an authentication procedure of the electronic device 101. As the registration with the network 701 is completed, the electronic device 101 may perform services provided by the network 701.

In operation 715, the electronic device 101 may prohibit transmission of a request signal for establishment of a PDU session.

The electronic device 101 may not transmit, to the network 701, a request message for establishment of a PDU session for a service that is not supported by the network 701. The electronic device 101 may prohibit (or refrain from) transmitting, to the network 701, a request message for establishment of a PDU session for a service that is not supported by the network 701. The electronic device 101 may not transmit a request message for the establishment of a PDU session for a service, which is not supported by the network 701, to the network 701, thereby reducing unnecessary consumption of resources due to transmission of a request message for establishing a PDU session.

According to an example, the electronic device 101 may be connected to the network 701 through first cellular communication. The first cellular communication may support the transmission or reception of SMS through a non-access stratum (NAS), and thus the first cellular communication may not require establishment of a separate PDU session for the SMS service.

The electronic device 101 may identify, based on the mapping data, that the network 701 connected through the first cellular communication supports only the SMS service (e.g., the first network 701) and may not transmit a signal requesting establishment of a separate PDU session to the node 520. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to the network 701 that does not support transmission and/or reception of data through the PDU session.

FIG. 8 is a diagram illustrating an embodiment in which an electronic device prohibits a request signal for establishment of a PDU session for a service that is not supported by a network according to an embodiment.

An electronic device (e.g., the electronic device 101 in FIG. 6) may transmit a registration request signal to a network 701 in operation 811.

The electronic device 101 may control the communication circuit 610 to search for the network 701 for connection to the network 701. If searching for the network 701 is successful, the electronic device 101 may perform a series of procedures to connect to the searched network 701.

The electronic device 101 may receive system information transmitted or broadcast by a node (e.g., the satellite 520 in FIG. 5) included in the network 701 (e.g., a non-terrestrial network) while performing searching for the network 701.

The electronic device 101 may identify whether the searched network 701 is a non-terrestrial network, based on the received system information.

The system information broadcast by the node 520 may include a variety of information. According to an example, the system information may include SIB 1 defined in 3GPP TS. 36.331 v15.6. SIB 1 may include identification information (e.g., mobile country code (MCC) and public land mobile network (PLMN)) of the network 701 including the node 520, information required to performing access (or random access (RA)) to the node 520, and/or information indicating that the network 701 is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

If it is identified that the identification information of the network 701 included in the system information transmitted or broadcast by the node 520 is specified identification information (e.g., identification information of a non-terrestrial network), the electronic device 101 may identify that the searched network 701 is a non-terrestrial network.

The electronic device 101 may identify that the searched network 701 is a non-terrestrial network, based on information indicating that the network 701 included in the system information transmitted or broadcast by the node 520 is a non-terrestrial network. According to an example, the electronic device 101 may identify that the searched network 701 is a non-terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as not barred. The electronic device 101 may identify that the searched network 701 is a terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as barred or that the cellBarredNTN IE is not included in the system information.

According to an example, the system information may include SIB 19 defined in 3GPP TS. 38.304. SIB 19 may include system information transmitted or broadcast when the network 701 including the node 520 is a non-terrestrial network and may include information related to the non-terrestrial network (e.g., altitude information of the node 520 and movement speed information of the node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by the node 520 is SIB 19, the electronic device 101 may identify that the searched network 701 is a non-terrestrial network.

The electronic device 101 may identify that the searched network 701 is a non-terrestrial network and identify services supported (or services not supported) by the searched network 701, based on mapping data stored in the memory 630.

The mapping data may be data in which the identification information of the non-terrestrial network and information of services supported by the non-terrestrial network are mapped and stored.

The electronic device 101 and the network 701 may perform a registration procedure for the electronic device 101 in operation 813.

The electronic device 101 may complete registration with respect to the network 701 through a series of operations including initial access to the node 520 included in the searched network 701 and an authentication procedure of the electronic device 101. As the registration with the network 701 is completed, the electronic device 101 may perform services provided by the network 701.

In operation 815, the electronic device 101 may transmit, to the network 701, a request message for establishment of a PDU session to perform services supported by the network.

The electronic device 101 may identify, based on the mapping data, that the network 701 connected through the first cellular communication or the second cellular communication supports the SMS service, MMS service, and transmission or reception of user data (e.g., the third network 701) and transmit, to the node 520, a signal requesting establishment of a PDU session for the MMS service and/or a signal requesting establishment of a PDU session for the user data transmission or reception service. The electronic device 101 may perform a series of procedures for establishing a PDU session for the user data transmission or reception service after transmitting the signal requesting the establishment of a PDU session for the user data transmission or reception service. The electronic device 101 may transmit data to the network 701 or receive data from the network 701 through the PDU session for the user data transmission or reception service.

However, the electronic device 101 may receive, from an application processor (e.g., the processor 120 in FIG. 1), a signal requesting to prohibit transmission and/or reception of user data by applications other than a specified application. The application processor 120 may pre-specify an application capable of performing the data transmission or reception through a non-terrestrial network, and the application processor 120 may prohibit applications other than the specified application from transmitting or receiving user data. According to an example, the application processor 120 may not transmit user data generated by applications other than the specified application to the electronic device 101. Even if the application processor 120 transmits user data generated by applications other than the specified application to the electronic device 101, the application processor 120 may control the electronic device 101 to not transmit the user data through the PDU session for the user data transmission or reception service.

In operation 817, the electronic device 101 may prohibit (or refrain from) transmitting a request signal for establishment of a PDU session to perform services that are not supported by the network.

However, the electronic device 101 may not transmit, to the node 520, a signal requesting establishment of separate PDU sessions for services (e.g., the user data transmission or reception service) other than the MMS service. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to the network 701 that does not support the user data transmission and/or reception through the PDU session.

FIG. 9 is a diagram illustrating an embodiment in which an electronic device transmits UE capability information excluding information related to functions that are not supported by a network according to an embodiment.

The network 701 may transmit a UE capability request message to the electronic device (e.g., the electronic device 101 in FIG. 6) in operation 911.

The electronic device 101 may receive the UE capability request message from the network 701 during a registration process in the network 701 or after being registered in the network 701.

After an RRC connection is established with the electronic device 101, the network 701 may transmit a UE capability request message to the electronic device 101 when UE capability information is required. The UE capability information may refer to information indicating the performance of the electronic device 101 in relation to cellular communication of the electronic device 101. For example, the UE capability information may include information indicating a frequency band capable of being supported by the electronic device 101 or information indicating a combination of frequency bands capable of being supported by the electronic device 101. The combination of frequency bands capable of being supported by the electronic device 101 may refer to a combination of frequency bands in which the electronic device 101 is able to perform simultaneous transmission or reception of data. For example, if the electronic device 101 may simultaneously perform both transmission (or reception) of a signal through a first frequency band and transmission (or reception) of a signal through a second frequency band, the combination of frequency bands capable of being supported by the electronic device 101 may be the first frequency band and the second frequency band.

In operation 913, the electronic device 101 may transmit UE capability information excluding information related to functions, which are not supported by the network 701, to the network 701.

Upon receiving the UE capability request message from the network 701, the electronic device 101 may transmit UE capability information to the network 701 through the node 520.

When transmitting the UE capability information, the electronic device 101 may transmit UE capability information excluding information that is not related to the network 701 (or not including information that is not related to the network 701) to the network 701.

According to an example, in the case where the network 701 is a non-terrestrial network, the network 701 may not support communication schemes (e.g., carrier aggregation (CA), E-UTRA-NR dual connectivity (EN-DC), or multi-RAT dual connectivity (MR-DC)) that support transmission or reception of data through a plurality of frequency bands. If the network 701 does not support transmission or reception of data through a plurality of frequency bands, the combination of frequency bands capable of being supported by the electronic device 101 may be unnecessary information for the network 701. Accordingly, the electronic device 101 may transmit UE capability information that does not include information indicating a combination of frequency bands supported by the electronic device 101 to the network 701, thereby reducing the time (or delay time) for transmission of the UE capability information.

FIG. 10 is an operational flowchart 1000 illustrating an operation method of an electronic device according to an embodiment.

An electronic device (e.g., the electronic device 101 or the communication processor 620 in FIG. 6) may identify whether the network is a non-terrestrial network, based on system information, in operation 1010.

The electronic device 101 may control a communication circuit (e.g., the communication circuit 610 in FIG. 6) to search for a network for connection to the network. If searching for the network is successful, the electronic device 101 may perform a series of procedures to connect to the searched network.

The electronic device 101 may receive system information transmitted or broadcast by a node (e.g., the satellite 520 in FIG. 5) included in the network (e.g., a non-terrestrial network) while performing searching for the network.

The electronic device 101 may identify whether the searched network is a non-terrestrial network, based on the received system information.

The system information broadcast by the node 520 may include a variety of information. According to an example, the system information may include SIB 1 defined in 3GPP TS. 36.331 v15.6. SIB 1 may include identification information (e.g., mobile country code (MCC) and public land mobile network (PLMN)) of the network including the node 520, information required to perform access (or random access (RA)) to the node 520, and/or information indicating that the network is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

If it is identified that the identification information of the network included in the system information transmitted or broadcast by the node 520 is specified identification information (e.g., identification information of a non-terrestrial network), the electronic device 101 may identify that the searched network is a non-terrestrial network.

The electronic device 101 may identify that the searched network is a non-terrestrial network, based on information indicating that the network included in the system information transmitted or broadcast by the node 520 is a non-terrestrial network. According to an example, the electronic device 101 may identify that the searched network is a non-terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as not barred. The electronic device 101 may identify that the searched network is a terrestrial network, based on identifying that the cellBarredNTN information element (IE) is indicated as barred or that the cellBarredNTN IE is not included in the system information.

According to an example, the system information may include SIB 19 defined in 3GPP TS. 38.304. SIB 19 may include system information transmitted or broadcast when the network including the node 520 is a non-terrestrial network and may include information related to the non-terrestrial network (e.g., altitude information of the node 520 and movement speed information of the node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by the node 520 is SIB 19, the electronic device 101 may identify that the searched network is a non-terrestrial network.

In operation 1020, the electronic device 101 may identify services supported by the network, based on mapping data.

The electronic device 101 may identify that the searched network is a non-terrestrial network and identify services supported (or services not supported) by the searched network, based on mapping data stored in the memory 630.

The mapping data may include data in which the identification information of the non-terrestrial network and information of services supported by the non-terrestrial network are mapped and stored.

Referring to Table 1, the mapping data may be data obtained by mapping a specific network to whether services are supported. For example, the electronic device 101, based on the mapping data, may identify that the first network (991-01) supports the SMS service but does not support the MMS service, user data transmission and/or reception service, and satellite PDU service. For example, the electronic device 101, based on the mapping data, may identify that the second network (992-02) supports the SMS service and MMS service but does not support the user data transmission and/or reception service and satellite PDU service. For example, the electronic device 101, based on the mapping data, may identify that the third network (993-03) supports the SMS service, MMS service, and user data transmission and/or reception service but does not support the satellite PDU service. For example, the electronic device 101, based on the mapping data, may identify that the fourth network (994-04) supports the SMS service, MMS service, and satellite PDU service but does not support the user data transmission and/or reception service. The satellite PDU service is a service for transmitting and/or receiving user data using a PDU capable of being used only by the non-terrestrial network, and may refer to a service for transmitting and/or receiving user data using a PDU incapable of being accessed through the terrestrial network.

In operation 1030, the electronic device 101 may prohibit (or refrain from) transmitting, to the network, a request message for establishment of a PDU session for a service that is not supported by the network.

The electronic device 101 may not transmit a request message for the establishment of a PDU session for a service, which is not supported by the network, to the network. The electronic device 101 may prohibit transmitting a request message for the establishment of a PDU session for a service, which is not supported by the network, to the network. The electronic device 101 may reduce unnecessary consumption of resources due to transmission of a request message for establishing a PDU session by not transmitting a request message for the establishment of a PDU session for a service, which is not supported by the network, to the network.

According to an example, the electronic device 101 may be connected to the network through first cellular communication. The first cellular communication may support the transmission or reception of SMS through a non-access stratum (NAS), and thus the first cellular communication may not require establishment of a separate PDU session for the SMS service.

The electronic device 101 may identify, based on the mapping data, that the network connected through the first cellular communication supports only the SMS service (e.g., the first network) and may not transmit a signal requesting establishment of a separate PDU session to the node 520. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to the network that does not support transmission and/or reception of data through the PDU session.

According to an example, the electronic device 101 may be connected to the network through second cellular communication. The second cellular communication may require establishment of a PDU session for the transmission and reception of SMS.

The electronic device 101 may identify, based on the mapping data, that the network connected through the second cellular communication supports only the SMS service (e.g., the first network) and transmit a signal requesting establishment of a PDU session for the SMS service to the node 520. However, the electronic device 101 may not transmit, to the node 520, a signal requesting establishment of separate PDU sessions for services other than the SMS service. Accordingly, the electronic device 101 may reduce unnecessary resource consumption or delay time caused by reception of a reject message that occurs when a signal requesting the establishment of a PDU session is transmitted to a network that does not support data transmission and/or reception through the PDU session.

The electronic device 101 may identify, based on the mapping data, that the network connected through the first cellular communication or the second cellular communication supports the SMS service and the MMS service but does not support the transmission or reception of user data (e.g., the second network) and transmit a signal requesting establishment of a PDU session for the MMS service to the node 520.
