Among them, AMF uses To control terminal access rights and handover functions, SMF is used to provide server continuity and uninterrupted user experience of the server, such as: IP address and anchor point changes.

The access network 12 includes several access network devices 120. The access network device 120 may be a base station, which is a device deployed in an access network to provide a wireless communication function for a terminal. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the Long Term Evolution (LTE) system, they are called eNodeB or eNB; in the 5G new air interface ( In the New Radio (NR) system, it is called gNode B or gNB. With the evolution of communication technology, the name "base station" may be described and will change.

Optionally, when the aforementioned terminal 13 accesses the access network device 120, it needs to meet the access bandwidth requirement of the access network device 120.

At present, 3GPP has carried out research on the Reduced Capability NR Devices (REDCAP) project of R17. The goal of the project is to reduce the complexity of the terminal and save the cost of the terminal on the basis of coexisting with the R15/16 terminal.

Illustratively, in some application scenarios with sensors, since the data type that the sensor needs to communicate is usually a simple value, the peak rate reference value agreed by the industry for these terminal devices is usually less than 5Mbps, so it is necessary to reduce the bandwidth of the capable terminal. When the capability is defined, the minimum bandwidth capability is less than 20M. In the current 5G New Radio (NR) R15/16, the base station is usually configured with a bandwidth of 20M, and the access bandwidth supported by the terminal needs to reach 20M.

That is, in related technologies, terminals with an initial access bandwidth of less than 20M do not support access to access network equipment.

As shown in Figure 2, the method includes:

Step 201: Obtain a first configuration instruction, where the first configuration instruction includes a first information field, and the first information field is used to indicate that the access network device allows the terminal with the target bandwidth to access.

Optionally, in response to the access network device allowing access by the terminal whose access bandwidth is the target bandwidth, the first configuration instruction is acquired.

Optionally, the access network device determines whether to allow the terminal with the target bandwidth to access through the master information block (Master Information Block, MIB); or, the access network device determines whether to allow the access according to the current bandwidth resource allocation. The incoming bandwidth is the terminal access of the target bandwidth.

Illustratively, taking the access network device determining whether to allow terminal access of the target bandwidth through the MIB as an example, the access network device obtains the MIB, and in response to including the second information field in the MIB, obtains the first configuration instruction, where the second The information field is used to indicate that the access network device allows the access of the terminal whose access bandwidth is the target bandwidth. Optionally, in order to be able to access the cell normally, the terminal needs to continue to read the system information of the cell after completing the frequency sweep and synchronization of the cell. The system information is the information repeatedly broadcasted by the access network equipment, and the system information is divided. It is MIB and System Information Block (SIB). When the access network device is turned on, it will send MIB first, and then send a series of SIBs. Optionally, when the MIB includes the second information field indicating that the access network device allows the terminal whose access bandwidth is the target bandwidth to access, the access network device sends a first configuration instruction to the terminal, and the first configuration instruction includes the first configuration instruction.

Illustratively, when the first information field includes an indication identifier, the indication access control information is displayed through the indication identifier. Optionally, the indication identifier is used to indicate that the access authority of the terminal within the specified bandwidth range is allowed to access, For example: when the indicator is 1, it means that the access network device allows terminals with the target bandwidth to access, and when the indicator is 0, it means that the access network equipment does not allow terminals with the target bandwidth to access, then in this embodiment, When the access network device allows the 10M bandwidth reduction capability terminal to access, the indicator value in the first information field is set to 1, indicating that the access network device allows the 10M bandwidth reduction capability terminal to access.

Therefore, when indicating whether the terminal of the target bandwidth is allowed to access in the DCI, the 1bit reserved field can be used to indicate whether the terminal of the target bandwidth is supported; or the 2bits reserved field can be used to indicate, for example: the first bit indicates the access network equipment Indicate the terminal access of the target bandwidth, and the second bit indicates the bandwidth range of the target bandwidth.
