ACCESS CONTROL METHOD AND APPARATUS, COMMUNICATION DEVICE, AND STORAGE MEDIUM

TECHNICAL FIELD

The present disclosure relates to, but is not limited to the technical field of wireless communications, and in particular to an access control method and apparatus, communication device, and storage medium.

BACKGROUND

To support networking services, two technologies of Machine-Type Communications (MTC) and Narrow Band Internet of Things (NB-IoT) are proposed. These two techniques are mainly aimed at low-rate and high-latency scenarios. For example, these may include scenarios such as meter reading and environmental monitoring. NB-IoT can support up to several hundred kbps (kilobyte per second) rates and MTC can support up to several Mbps (megabyte per second) rates. However, with the continuous development of Internet of Things services, such as video monitoring, smart home, wearable devices and industrial sensor monitoring services are popular. These services usually require rates of several tens to 100 M and have relatively high requirements for delay, so that MTC and NB-IoT techniques are difficult to meet.

In a new radio technology, new terminals are introduced to meet the requirements of mid-end Internet of Things equipment. Such terminals are called reduced capability (Redcap) or NR-lite for short. After the introduction of RedCap user equipment, how to realize the access control of RedCap user equipment is a problem to be considered.

Referring to FIG. 1, a structural diagram of a wireless communication system provided by an embodiment of the present disclosure is shown. As shown in FIG. 1, the wireless communication system is a communication system based on mobile communication technology, and the wireless communication system may comprise: several user equipment 110 and several base stations 120.

User equipment 110 may be, among other things, a device that provides voice and/or data connectivity to a user. The user equipment 110 may communicate with one or more core networks via a Radio Access Network (RAN), and the user equipment 110 may be an Internet of Things user equipment, such as a sensor device, a mobile phone, and a computer having the Internet of Things user equipment, and may be, for example, a fixed, portable, pocket, hand-held, computer-built or vehicle-mounted apparatus. For example, a Station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user equipment, or user equipment. Alternatively, the user equipment 110 may be a device of an unmanned aerial vehicle. Alternatively, the user equipment 110 may be an on-board device, such as a driving computer with wireless communication capability, or a wireless user equipment connected to the driving computer. Alternatively, the user equipment 110 may be a roadside device, such as a street light, signal light, or other roadside device having wireless communication capabilities.

Base station 120 may be network side equipment in a wireless communication system. Wherein the wireless communication system can be the 4th generation mobile communication (4G) system, also known as a long-term evolution (LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a further generation of the 5G system. Among others, the access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network).

The base station 120 may be an evolved base station (eNB) used in a 4G system. Alternatively, base station 120 may be a gNB in a 5G system using a centralized distributed architecture. When the base station 120 employs a centralized architecture, it typically includes a centralized central unit (CU) and at least two distributed units (DU). A protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control protocol (RLC) layer, and a media access control (MAC) layer is provided in the concentration unit; the distribution unit is provided with a Physical (PHY) layer protocol stack, and embodiments of the present disclosure do not limit the specific implementation of the base station 120.

A wireless connection may be established between the base station 120 and the user equipment 110 over a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; alternatively, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on 5G's next generation mobile communication network technology standard.

Here, the user equipment described above may be regarded as the terminal device of the following embodiments.

In some embodiments, the wireless communication system may further include network management equipment 130.

Several base stations 120 are respectively connected to network management equipment 130. The network management equipment 130 may be a core network device in a wireless communication system, for example, the network management equipment 130 may be a mobility management entity (MME) in an evolved packet core network (EPC). Alternatively, the network management equipment may be another core network device, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS), etc. Embodiments of the present disclosure are not limited to the implementation form of the network management equipment 130.

In order to facilitate the understanding of those skilled in the art, the disclosed examples set forth a plurality of embodiments to clearly illustrate embodiments of the present disclosure. Of course, those skilled in the art will appreciate that embodiments of the present disclosure provide a plurality of embodiments that can be implemented separately, can also be executed in combination with the methods of other embodiments in embodiments of the present disclosure, and can also be executed alone or in combination with some methods of other related art; the embodiments of this disclosure are not intended to be limiting.

In order to better understand the technical solution described in any of embodiments of the present disclosure, firstly, an application scenario in the related art is described.

In the fourth-generation mobile communication network system 4G of the long-term evolution LTE network, to support networking services, two technologies of Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT) are proposed. These two techniques are mainly aimed at low-rate and high-latency scenarios. For example, scenarios such as meter reading and environmental monitoring. In the related art, NB-IoT can support up to several hundred k rates, and MTC can currently support up to several M rates. On the other hand, however, with the continuous development of Internet of Things services, such as video monitoring, smart home, wearable devices, and industrial sensor monitoring services have become popular. These services typically require rates of tens to 100 M, with relatively high requirements for delay. Therefore, the MTC and NB-IoT techniques in LTE are difficult to meet. On this basis, the requirement of redesigning a new user equipment in the 5G new radio to cover the Internet of Things equipment is proposed. This new terminal type is called reduced capability user equipment UE or NR-lite for short.

Like the Internet of Things devices in LTE, 5G NR-lite generally needs to meet the following requirements: 1. low cost and low complexity; 2. a certain degree of coverage enhancement; 3. power savings.

Since the NR new radio is designed for high-end terminals with high rate and low delay, the related design cannot meet the above requirements of NR-lite. Therefore, the NR system needs to be modified to meet the requirements of NR-lite. For example, to meet the requirements of low cost and low complexity, the RF bandwidth of NR-IoT can be limited, for example to 5 MHz or 10 MHz; or the size of the buffer of the NR-lite is limited, thereby limiting the size of each received transmission block, etc.

In an embodiment, to allow the network flexibility to control which RedCap user equipment is allowed to access, access control is supported for different reception antenna branches (Rx branches for short). Considering that RedCap supports 1 and 2 Rx branches, respectively, 2 access control bits are introduced in the system message to indicate whether RedCap user equipment with the number of 1 and 2 Rx branches is allowed, respectively.

In an embodiment, the RedCap user equipment supports 1 and 2 Rx branches under FR1, respectively. However, a different antenna structure is provided under FR2. Illustratively, the terminals have the same number of Rx branches under FR2, but different antenna elements for a certain Rx branch. The previous access control mechanism with different Rx branches is then no longer applicable under FR2.

As shown in FIG. 2, an access control method is provided in embodiment of the present disclosure, where the method is performed by an access network device, and the method includes:

Step 21, send indication information to a terminal, where the indication information indicates whether all first-type terminals are allowed to access a network, or the indication information indicates whether some first-type terminals are allowed to access a network.

Here, the first-type terminals to which the present disclosure relates may be, but are not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device and/or a medical device, etc. In some embodiments, the first-type terminal may be a RedCap user equipment or a predetermined version of a new radio NR terminal (e.g., an NR terminal of R17). The second-type terminals referred to in the present disclosure may be terminals of R15 and R16.

The access network device referred to in the present disclosure may be a base station. Here, the base station may be various types of base stations, for example, a base station of a third-generation mobile communication (3G) network, a base station of a fourth-generation mobile communication (4G) network, a base station of a fifth-generation mobile communication (5G) network, or other evolved type base stations.

In an embodiment, the first-type terminal may be provided with a different number of Rx branches. Illustratively, the first-type terminal may be provided with 1 or 2 Rx branches.

In an embodiment, the Rx branches of the first-type terminals may be provided with a different number of antenna elements. Illustratively, the Rx branches of the first-type terminals may be provided with 3 or 4 antenna elements.

It should be noted that some first-type terminals may be those having the same number of Rx branches among all first-type terminals. Some first-type terminals may also be first-type terminals all having the same Rx branches and the same number of antenna elements of the Rx branches.

In an embodiment, indication information is sent to a terminal, where the indication information indicates that all first-type terminals are allowed to access a network, or the indication information indicates that all first-type terminals are not allowed to access a network. Illustratively, when the information field bearing the indication information indicates a first value, all first-type terminals are allowed to access a network; or when the information field bearing the indication information indicates the second value, all first-type terminals are not allowed to access a network. Here, not allowing all first-type terminals to access a network may be allowing only some first-type terminals to access a network. It should be noted that as long as the terminals are the first-type terminals, the terminals belong to those of “all first-type terminals” regardless of the number of Rx branches of the terminal and/or the number of antenna elements of the Rx branches.

Here, not allowing all first-type terminals to access a network may also be understood as prohibiting all first-type terminals from accessing the network.

In an embodiment, indication information is sent to a terminal, where the indication information indicates that some of first-type terminals are allowed to access a network, or the indication information indicates that some of first-type terminals are not allowed to access a network. Illustratively, when an information field bearing indication information indicates a first value, some first-type terminals are allowed to access a network; or when the information field bearing the indication information indicates the second value, some first-type terminals are not allowed to access a network. Here, some first-type terminals that are not allowed to access a network may be some first-type terminals that are not allowed to access a network with a predetermined feature. The predetermined feature may be the number of Rx branches of the first-type terminals and/or the number of antenna elements of the Rx branches. It should be noted that if the first-type terminals has the predetermined feature, the first-type terminals belongs to the terminals among “some first-type terminals”.

Here, not allowing some first-type terminals to access a network may also be understood as prohibiting some first-type terminals to access a network.

In an embodiment, after receiving the indication information, any of the first-type terminals may be allowed to access a network if it is determined that the indication information indicates that all first-type terminals are allowed to access a network. or if it is determined that the indication information indicates that all first-type terminals are not allowed to access a network, any of the first-type terminals may determine whether there is a predetermined feature, the first-type terminals may be allowed to access a network if there is the predetermined feature and the indication information indicates that the first-type terminals having the predetermined feature are allowed to access a network, or the first-type terminals may not be allowed to access a network if there is the predetermined feature and the indication information indicates that the first-type terminals having the predetermined feature are not allowed to access a network.

In an embodiment, after receiving the indication information, any of the first-type terminals may determine whether it has a predetermined feature that some first-type terminals should have if it is determined that the indication information indicates that some first-type terminals are allowed to access a network, the first-type terminal may be allowed to access a network if it has the predetermined feature, or the first-type terminal may not be allowed to access a network if it has no predetermined feature.

In an embodiment, after receiving the indication information, if it is determined that the indication information indicates that some first-type terminals are not allowed to access a network, any of the first-type terminals may determine whether it has a predetermined feature that some first-type terminals should have, and if it has the predetermined feature, the first-type terminal may not be allowed to access a network, or if it has no predetermined feature, the first-type terminal may be allowed to access a network.

In an embodiment, the information fields of the indication information may be divided for different predetermined features, the different information fields corresponding to one of the predetermined features. For example, the information field is divided into a first information field for indicating whether the first-type terminals whose number of Rx branches is a first predetermined number are allowed to access a network and a second information field for indicating whether the first-type terminals of which the number of antenna elements of the Rx branches is a second predetermined number are allowed to access a network.

For example, if the value of the first information field is “1” and the value of the second information field is also “1”, the first-type terminals of which the number of Rx branches is a first predetermined number and the number of antenna elements of the Rx branches is a second predetermined number are allowed to access a network. or if the value of the first information field is “1” and the value of the second information field is also “0”, the first-type terminals of which the number of Rx branches is a first predetermined number and the number of antenna elements of the Rx branches is a second predetermined number are not allowed to access a network.

In an embodiment, indication information is sent to a terminal based on the system message, where the indication information indicates whether all first-type terminals are allowed to access a network or the indication information indicates whether some first-type terminals are allowed to access a network.

In an embodiment of the present disclosure, indication information is sent to a terminal, where the indication information indicates whether all first-type terminals are allowed to access a network, or the indication information indicates whether some first-type terminals are allowed to access a network. As such, since the indication information sent by the access network device to the terminal indicates: whether all first-type terminals are allowed to access a network, or whether some first-type terminals are allowed to access a network. After the terminal receives the indication information, it can be determined whether to access a network according to the indication of the indication information, and the reliability of the first-type terminal accessing the network can be improved compared to when the first-type terminal can access a network cannot be clearly determined.

It should be noted that a person skilled in the art can understand that the method provided in embodiments of the present disclosure can be performed alone or together with some methods in embodiments of the present disclosure or some methods in the related art.
