The disclosure relates to an electronic device and a method of operating the electronic device and a technology for configuring an operating mode of an interface between an application processor and a communication module, based on the maximum data rate of multiple links.
With the proliferation of various electronic devices, improvements have been made in the speed of wireless communication that can be used by various electronic devices. Among the wireless communications supported by recent electronic devices, IEEE 802.11 wireless local area network (WLAN) (or wireless fidelity (Wi-Fi)) is a standard for implementing high-speed wireless connections on various electronic devices. The first implemented Wi-Fi could support transmission speeds of a maximum of 1 to 9 Mbps, but Wi-Fi 6 technology (or IEEE 802.11 ax) may support transmission speeds of a maximum of about 10 Gbps.
Electronic devices may support various services (e.g., ultra-high definition (UHD)-quality video streaming service, augmented reality (AR) service, virtual reality (VR) service, or mixed reality (MR) service) using relatively large capacity data through wireless communication supporting high transmission rates, and various other services may be supported.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
The electronic device may generate a channel for data exchange with an external electronic device (or an access point (AP)) and transmit or receive data through the generated channel.
The electronic device may provide an interface between an application processor and a communication module, the interface being used to transmit and/or receive data. The interface may support multiple operating modes with different maximum data rates. However, a situation may occur where the maximum data rate of the channel generated between the electronic device and the external electronic device and the maximum data rate supported by the operating mode of the interface are significantly different. In this case, a decrease in the data transmission rate (or reception rate) and/or an increase in power consumption may occur.
Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device and a method of operating the electronic device and a technology for configuring an operating mode of an interface between an application processor and a communication module, based on the maximum data rate of multiple links.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device include memory storing one or more computer programs, a communication module including a communication circuit supporting short-range wireless communication through multiple links, one or more processors communicatively coupled to the memory and the communication module, and an application processor electrically connected to the communication module through an interface supporting multiple operating modes, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to: identify the maximum data rate of each of the multiple links, based on capability information of an external electronic device, received from the external electronic device, identify the maximum data rate of the multiple links, based on an operating mode for the short-range wireless communication, select one of the multiple operating modes of the interface, based on the maximum data rate of the multiple links, and transmit data to the application processor through the selected operating mode, or receive data, transmitted by the application processor, through the selected interface.
In accordance with another aspect of the disclosure, a method of operating an electronic device is provided. The method includes identifying the maximum data rate of each of multiple links for short-range wireless communication, based on capability information of an external electronic device, received from the external electronic device, determining the maximum data rate of the multiple links, based on an operating mode for the short-range wireless communication, based on the maximum data rate of the multiple links, selecting one of multiple operating modes supported by an interface between an application processor and a communication module, and transmitting data to the application processor through the selected operating mode, or receiving data, transmitted by the application processor, through the selected interface.
In accordance with another aspect of the disclosure, one or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations is provided. The operations include identifying the maximum data rate of each of multiple links for short-range wireless communication, based on capability information of an external electronic device, received from the external electronic device, determining the maximum data rate of the multiple links, based on an operating mode for the short-range wireless communication, based on the maximum data rate of the multiple links, selecting one of multiple operating modes supported by an interface between an application processor and a communication module, and transmitting data to the application processor through the selected operating mode, or receiving data, transmitted by the application processor, through the selected interface.
According to an electronic device and a method for operating an electronic device according to various embodiments of the disclosure, the maximum data rate of multiple links is determined based on an operating mode for short-range wireless communication and capability information of an external electronic device, received in the process of establishing multiple links between the external electronic device and the electronic device. The electronic device selects (or determines) an operating mode of an interface, based on the maximum data rate of multiple links, and transmits data through an interface in which the selected operating mode is active. The selected operating mode is an operating mode supporting a higher data rate than the maximum data rate of the multiple links. Accordingly, the electronic device prevents a bottleneck phenomenon that occurs by operating in an operating mode supporting a data rate lower than the maximum data rate of the multiple links.

The electronic device 310 and/or the external electronic device 320 may support multi-link operation (MLO). Multi-link operation may be an operation method in which data is transmitted or received through multiple links (e.g., the first link 331 and the second link 332). Multi-link operation may be an operating mode scheduled to be introduced in IEEE 802.11be and may be an operation method in which data is transmitted or received through multiple links based on multiple bands or channels.
According to another embodiment, the electronic device 310 may include multiple communication circuits (e.g., a first communication circuit 311 and/or a second communication circuit 312) to support multi-link operations. The first communication circuit 311 may transmit data to the external electronic device 320 through the first link 331, or receive data transmitted by the external electronic device 320 through the first link 331. The first communication circuit 311 may output or receive a signal in the frequency band corresponding to the first link 331 through the first antenna 313. The second communication circuit 312 may, for example, transmit data to the external electronic device 320 through the second link 332, or receive data transmitted by the external electronic device 320 through the second link 332. The second communication circuit 312 may output or receive a signal in the frequency band corresponding to the second link 332 through the second antenna 314.
The external electronic device 320 may include multiple communication circuits (e.g., a third communication circuit 321 and/or a fourth communication circuit 322) to support multi-link operations.

According to various embodiments of the disclosure, the frequency band of the first link 331 and the frequency band of the second link 333 may be different from each other. For example, the frequency band of the first link 331 may be 2.5 GHZ, and the frequency band of the second link 332 may be 5 GHZ. Alternatively, the frequency band of the first link 331 and the frequency band of the second link 333 may be the same, but the channel number of the first link 331 and the channel number of the second link 333 may be different. For example, the first link 331 may be channel 1 of the 2.4 GHz frequency band, and the second link 333 may be channel 12 of the 2.4 GHZ frequency band.
The electronic device 310 may not sufficiently secure a space 431 between the first antenna 313 and the second antenna 314 due to implementation reasons. According to another embodiment, when the space 431 between the first antenna 313 and the second antenna 314 is not sufficiently secured, the signal output from the first antenna 313 and the signal received through the second antenna 314 may interfere with each other. For example, the second antenna 314 may receive a signal in which the signal received through the second link 332 and a portion of the signal output from the first antenna 313 are combined, thereby causing the quality of the signal received through the second link 332 to deteriorate.
The electronic device 310 may support non-simultaneous transmission and reception (STR) mode to prevent the situation where the signal output from the first antenna 313 and the signal output from the second antenna 314 interfere with each other. The non-STR mode may, for example, refer to a mode in which the electronic device 310 does not receive data through the second link 332 at the time of transmitting data to the external electronic device 320 through the first link 331. The non-STR mode may support the operation of receiving data through the second link 332 while data is received through the first link 331 and/or the operation of transmitting data through the second link 332 while data is transmitted through the first link 331.

According to various embodiments of the disclosure, the electronic device 310 may, for implementation reasons, support a multi-link operation in which multiple links are used by one communication circuit (e.g., the first communication circuit 311).

When relatively large size data is transmitted to the external electronic device 320 through the first link 331, the electronic device 310 operating in the EMLSR mode may not receive data through the second link 333.

When the electronic device 310 operates in a mode in which data transmission through one of multiple links is possible, the processor 510 may determine, as the maximum data rate (e.g., 1147.1 Mbps) of multiple links, the largest value (e.g., the maximum data rate 1147.1 Mbps of the first link 331) among the maximum data rates of each of the multiple links (e.g., the maximum data rate 1147.1 Mbps of the first link 331 and the maximum data rate 1032.4 Mbps of the second link 332) generated between the electronic device 310 and the external electronic device 320.
The processor 510 may determine the maximum data rate of the multiple links, based on the operating mode for short-range wireless communication, and may select one of the multiple operating modes of the interface 413, based on the maximum data rate of the multiple links.
The processor 510 may select an operating mode that supports a data rate higher than the maximum data rate, as the operating mode in which the interface 413 is to operate. For example, the processor 510 may select one of operating modes (e.g., a second operating mode, a third operating mode, a fourth operating mode, and/or a fifth operating mode) that supports a data rate higher than the maximum data rate (e.g., 2179.5 Mbps) of the multiple links, as the operating mode in which the interface 413 is to operate. According to another embodiment, the processor 510 may select an operating mode (e.g., a second operating mode) having the lowest maximum data rate among operating modes that support a data rate higher than the maximum data rate of multiple links, as the operating mode in which the interface 413 is to operate, thereby preventing bottlenecks and reducing power consumption.
In response to identifying that the interface 413 is operating in an operating mode different from the selected operating mode, the processor 510 may control the interface 413 to operate in the selected operating mode. The processor 510 may control the interface 413 to transition the state of the interface 413 from an active state (e.g., LO, L0s, or L1) to a recovery state, and to change the operating mode in the recovery state. The recovery state may be a temporarily transitioned state to change the operating mode of the interface 413. The processor 510 may, for example, change the operating mode of the interface 413 after the authentication operation between the external electronic device 320 and the electronic device 310 has been completed during the operation of activating multiple links between the external electronic device 320 and the electronic device 310, after receiving an association response frame, or during the generation and/or transmission of an association request frame. In response to the completion of the transition of the operating mode of the interface 413, the processor 510 may perform various operations for establishing a channel (e.g., an association operation between an external electronic device 320 and the electronic device 310) and complete the activation operation of multiple links.
The processor 510 may receive data, transmitted by the application processor 411, through the interface 413 operating in the selected operating mode and transmit the data to the external electronic device 320. Alternatively, the processor 510 may transmit data, transmitted by the external electronic device 320, to the application processor 411 through the interface 413 operating in the selected operating mode.
When it is detected that the state of at least one link among the multiple activated links between the electronic device 310 and the external electronic device 320 changes, the processor 510 may re-identify the maximum data rate of the multiple links (alternatively, it may identify whether the maximum data rate of multiple links has changed).
The processor 510 may, based on a traffic identifier (TID) to link mapping frame transmitted by the application processor 411, identify whether the state of at least one of multiple links activated between the electronic device 310 and the external electronic device 320 changes.
The TID to link mapping frame may be data indicating a link on which data with a specific TID is to be transmitted or received. The TID to link mapping frame may be data in which a TID and a link through which the TID is to be transmitted or received are mapped to each other. The processor 510 may receive the TID to link mapping frame and, based on identifying that at least one link among the multiple links is not included in the TID to link mapping frame, may identify that the at least one link has transitioned from the active state to the inactive state. Alternatively, the processor 510 may receive the TID to link mapping frame and, based on identifying that at least one link among the multiple links is newly included in the TID to link mapping frame, may identify that the at least one link has transitioned from the inactive state to the active state.
The processor 510 may, upon detecting a change in the power mode, identify whether the state of at least one link among the multiple links has changed. The processor 510 may identify whether the power mode is changed, based on information transmitted by the external electronic device 320 and included in the frame for controlling the power mode, the information indicating whether the power saving mode is active or not. According to an example, in a state in which the power saving mode is active, when the processor 510 receives a frame for controlling the power mode and including information indicating a state in which the power saving mode is inactive, the processor 510 may transition at least one of multiple links from an inactive state to an active state.
In an embodiment, when it is detected that the state of at least one of the activated multiple links between the electronic device 310 and the external electronic device 320 has changed, the processor 510 may re-identify the maximum data rate of the multiple links (or identify whether the maximum data rate of the multiple links has changed) and, when the maximum data rate has changed, may change (or maintain) the operating mode of the interface 413 according to the changed maximum data rate.
The processor 510 may identify that the changed maximum data rate (e.g., 3000 Mbps) is greater than the maximum data rate (e.g., 2 Gbps) of the current operating mode (e.g., first operating mode) of the interface 413, and may control the interface 413 to operate in one of operating modes (e.g., a second operating mode, a third operating mode, a fourth operating mode, and/or a fifth operating mode) that support a data rate greater than the changed maximum data rate. The processor 510 may select, as an operating mode in which the interface 413 is to operate, an operating mode (e.g., a second operating mode) having the lowest maximum data rate among operating modes that support a data rate greater than the maximum data rate of multiple links, thereby preventing bottlenecks and reducing power consumption.
In another embodiment, the processor 510 may support various wireless communication modes defined in short-range wireless communication. Various wireless communication modes may include a station (STA) mode in which the electronic device 310 receives or transmits data from or to various external electronic devices through the external electronic device 320, a peer-to-peer (P2P) mode (or Wi-Fi direct mode) in which the electronic device 310 is directly connected to an external electronic device (e.g., the external electronic device 102 of

For example, the capability information of the other external electronic device 102 may include information regarding the generation of short-range wireless communication (e.g., Wi-Fi 4, Wi-Fi 5, Wi-Fi 6, Wi-Fi6e, and/or Wi-Fi 7) supported by the other external electronic device 102, channel bandwidth information, information indicating the maximum data rate, and/or information indicating the modulation and coding scheme (MCS).

In connection with performing short-range wireless communication with another external electronic device 102, the processor 510 may select a link to connect the electronic device 310 with the other external electronic device 102.
According to an example, the processor 510 may select one of multiple links, generated between the electronic device 310 and the external electronic device 320, as a link to connect the electronic device 310 with the other external electronic device 102.
After selecting a link, the processor 510 may determine characteristics of the selected link, based on capability information of the other external electronic device 102, as part of the operation of link configuration. Determining the characteristics of the selected link may be performed after selecting a link to be activated or during the procedure of selecting a link to be activated. According to an example, the characteristics of the link may include the size of the bandwidth of the link, the MCS level of data to be transmitted or received through the link, and/or the number of spatial streams.
The processor 510 may identify the information related to the selected link and included in the capability information of the other external electronic device 102 (e.g., identification information of APs supporting each of the multiple links, bandwidth information of each of the multiple links, the MCS level of data to be transmitted or received through the multiple links, and the number of spatial streams (NSS) of each of the multiple links), and may determine the characteristics of the link by considering the capability that the electronic device 310 can support.
In another embodiment, the processor 510 may control the interface 413 to perform short-range wireless communication. The processor 510 may identify the maximum data rate of data to be transmitted or received through multiple links activated between the electronic device 310 and the external electronic device 320, and select an operating mode in which the interface 413 is to operate based on the maximum data rate.
According to an example, in the case of selecting one of multiple links, generated between the electronic device 310 and the external electronic device 320, as a link to connect the electronic device 310 with the other external electronic device 102, the processor 510 may determine, as the maximum data rate of the selected link, the larger value between the maximum data rate of the data transmitted and/or received through the selected link in the electronic device 310 and the external electronic device 320 and the maximum data rate of the data transmitted and/or received through the selected link in the electronic device 310 and the other external electronic device 102.
In an example, in case that a first link (e.g., the first link 331 of

Based on identifying that the external electronic device 320 does not support data transmission and/or reception using the multiple links (“N” in operation 820), the electronic device 310 may identify the maximum data rate for one link, based on capability information of the external electronic device 320, in operation 840.
In operation 850, the electronic device 310 may identify the maximum data rate of multiple links, based on the operating mode for short-range wireless communication.
The electronic device 310 may, for example, identify the maximum data rate of each of the multiple links to be activated between the electronic device 310 and the external electronic device 320, and identify the maximum data rate of the multiple links, based on the operating mode for short-range wireless communication. The maximum data rate of the multiple links may mean the maximum data rate of data transmitted by the electronic device 310 to the external electronic device 320.
The operating mode for short-range wireless communication may include a mode (e.g., multi-link operation (MLO)) of transmitting or receiving data through multiple links. A mode (e.g., multi-link operation (MLO)) of transmitting or receiving data through multiple links may include a mode in which simultaneous data transmission through multiple links is possible (e.g., multi-link multi-radio (MLMR), enhanced multi-link multi-radio (EMLMR)) and a mode in which data transmission through one of multiple links is possible (e.g., multi-link single-radio (MLSR), enhanced multi-link single-radio (EMLSR)). When the electronic device 310 operates in a mode in which simultaneous data transmission is possible through multiple links, the electronic device 310 may transmit data through one link while data transmission through another link is performed. When the electronic device 310 operates in a mode in which data transmission is possible through one of multiple links, the electronic device 310 may not be able to transmit data through another link while data transmission through one link is performed.

A mode in which the electronic device 310 is capable of simultaneously transmitting data through multiple links is a mode in which simultaneous data transmission through multiple links is possible, and in which the sum of the maximum data rates of each of the multiple links may be the maximum data rate of the multiple links.
According to an example, the electronic device 310 may, based on the capability information of the external electronic device 320, identify the maximum data rate of multiple links (e.g., the first link 331 and the second link 332) (e.g., the maximum data rate 1147.1 Mbps of the first link 331, and the maximum data rate 1032.4 Mbps of the second link 332). When the electronic device 310 operates in a mode in which data transmission through multiple links is possible, the electronic device 310 may determine, as the maximum data rate (e.g., 2179.5 Mbps) of multiple links, the sum of the maximum data rates (e.g., 1147.1 Mbps+1032.4 Mbps) of each of the multiple links generated between the electronic device 310 and the external electronic device 320.
In an embodiment, when the electronic device 310 operates in a mode in which data transmission through one of multiple links is possible, the electronic device 310 may determine, as the maximum data rate of the multiple links, the largest data rate among the maximum data rates of each of the multiple links generated between the electronic device 310 and the external electronic device 320.
A mode in which the electronic device 310 is capable of transmitting data through one of multiple links is a mode in which while data transmission through one of multiple links is performed, data transmission through another link is impossible. The largest value among the maximum data rates of each of the multiple links may be the maximum data rate of multiple links.
According to an example, the electronic device 310 may, based on the capability information of the external electronic device 320, identify the maximum data rate of multiple links (e.g., the first link 331 and the second link 332) (e.g., the maximum data rate 1147.1 Mbps of the first link 331, and the maximum data rate 1032.4 Mbps of the second link 332). When the electronic device 310 operates in a mode in which data transmission through one of multiple links is possible, the electronic device 310 may determine, as the maximum data rate (e.g., 1147.1 Mbps) of multiple links, the largest value (e.g., the maximum data rate 1147.1 Mbps of the first link 331) among the maximum data rates of each of the multiple links (e.g., the maximum data rate 1147.1 Mbps of the first link 331 and the maximum data rate 1032.4 Mbps of the second link 332) generated between the electronic device 310 and the external electronic device 320.

The electronic device 310 may determine the maximum data rate of the multiple links, based on the operating mode for short-range wireless communication, and may select one of the multiple operating modes of the interface 413, based on the maximum data rate of the multiple links.
According to one embodiment, the electronic device 310 may select an operating mode that supports a data rate higher than the maximum data rate, as the operating mode in which the interface 413 is to operate. For example, the electronic device 310 may select one of operating modes (e.g., a second operating mode, a third operating mode, a fourth operating mode, and/or a fifth operating mode) that supports a data rate higher than the maximum data rate (e.g., 2179.5 Mbps) of the multiple links, as the operating mode in which the interface 413 is to operate. According to an embodiment, the electronic device 310 may select an operating mode (e.g., a second operating mode) having the lowest maximum data rate among operating modes that support a data rate higher than the maximum data rate of multiple links, as the operating mode in which the interface 413 is to operate, thereby preventing bottlenecks and reducing power consumption.
According to an example, the electronic device 310 may select a third operating mode (e.g., PCIe 2.0) when the maximum data rate of multiple links is equal to or greater than a designated value (e.g., 4 Gbps). The electronic device 310 may select a second operating mode (e.g., PCIe 2.0) when the maximum data rate of the multiple links is less than or equal to (or less than) a designated value (e.g., 4 Gbps).

The maximum data rate of a single link between the external electronic device 320 and the electronic device 310 may be determined based on capability information of the external electronic device 320. According to an example, the electronic device 310 may identify the maximum data rate, based on the characteristics (e.g., MCS level, number of spatial streams) of the link between the electronic device 310 and the external electronic device 320 and mapping data. The electronic device 310 may, based on the maximum data rate, select one of the multiple operating modes of the interface 413.
Alternatively, the external electronic device 320 does not support data transmission and/or reception using multiple links (“N” in operation 820), the electronic device 310 may select one of the multiple operating modes of the interface 413, based on the maximum bandwidth of a single link between the external electronic device 320 and the electronic device 310.
According to an example, in case that the maximum bandwidth of a single link between the external electronic device 320 and the electronic device 310 is greater than or equal to (or greater than) a designated value (e.g., 320 MHZ) (or, in case that a single link between the external electronic device 320 and the electronic device 310 supports the maximum bandwidth defined in Wi-Fi 7), the electronic device 310 may select a third operating mode (e.g., PCIe 3.0). In case that the maximum bandwidth of a single link between the external electronic device 320 and the electronic device 310 is equal to or less than (or less than) a designated value (e.g., 320 MHZ) (or, in case that a single link between the external electronic device 320 and the electronic device 310 does not support the maximum bandwidth defined in Wi-Fi 7), the electronic device 310 may select a second mode of operation (e.g. PCIe 2.0).
In response to identifying that the interface 413 is operating in an operating mode different from the selected operating mode, the electronic device 310 may control the interface 413 to operate in the selected operating mode. The electronic device 310 may control the interface 413 to transition the state of interface 413 from an active state (e.g., LO, L0s, or L1) to a recovery state, and to change the operating mode in the recovery state. The recovery state may be a temporarily transitioned state to change the operating mode of the interface 413. The electronic device 310 may change the operating mode of the interface 413 after the authentication operation between the external electronic device 320 and the electronic device 310 has been completed during the operation of activating multiple links between the external electronic device 320 and the electronic device 310, after receiving the association response frame, or during the generation and/or transmission of the association request frame. In response to the completion of the transition of the operating mode of the interface 413, the electronic device 310 may perform various operations for establishing a channel (e.g., an association operation between an external electronic device 320 and the electronic device 310) and complete the activation operation of multiple links.
In operation 870, the electronic device 310 may transmit and/or receive data through the interface 413 operating in the selected operating mode.

The electronic devices may include, for example, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.
It should be appreciated that various embodiments of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used in connection with various embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Various embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to various embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, according to various embodiments, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
It will be appreciated that various embodiments of the disclosure according to the claims and description in the specification can be realized in the form of hardware, software or a combination of hardware and software.
Any such software may be stored in non-transitory computer readable storage media. The non-transitory computer readable storage media store one or more computer programs (software modules), the one or more computer programs include computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform a method of the disclosure.
Any such software may be stored in the form of volatile or non-volatile storage such as, for example, a storage device like read only memory (ROM), whether erasable or rewritable or not, or in the form of memory such as, for example, random access memory (RAM), memory chips, device or integrated circuits or on an optically or magnetically readable medium such as, for example, a compact disk (CD), digital versatile disc (DVD), magnetic disk or magnetic tape or the like. It will be appreciated that the storage devices and storage media are various embodiments of non-transitory machine-readable storage that are suitable for storing a computer program or computer programs comprising instructions that, when executed, implement various embodiments of the disclosure. Accordingly, various embodiments provide a program comprising code for implementing apparatus or a method as claimed in any one of the claims of this specification and a non-transitory machine-readable storage storing such a program.
While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
