Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

Unified access control (UAC) is a mechanism introduced in the 5G system to control terminal access to the network. The purpose is to relieve network congestion on the base station side. Before sending an RRC connection establishment request to the base station, the terminal determines whether it can initiate RRC connection establishment request, if the RRC connection establishment request cannot be initiated, the terminal does not send the RRC connection establishment request to the base station, and the terminal waits for the RRC connection establishment request to be sent to the base station before sending the RRC connection establishment request to the base station. Network load on the base station side. This mechanism supports all services and applies to all states of the terminal: idle state, deactivated state and connected state. In the process of unified access control, the base station broadcasts access control information in a system message (System Information Block, SIB), where the access control information is a list of access parameters associated with access identifiers and access categories , that is, the blocking parameter set consisting of blocking factor and blocking time. The terminal determines whether to allow access requests of the same access category based on the set of blocking parameters and the terminal configuration. In the process of unified access control, the non-access stratum is responsible for mapping different access requests and users with different priorities into one access class and one or more access identities, while the access stratum is responsible for mapping different access requests and users with different priorities into one access class and one or more access identities. Identification and the set of blocking parameters broadcast by the network to decide whether to allow access.

For the requirements of the current 3GPP TS24.501 on the unified access control section, the usual mechanism for a terminal to process a certain network access request (such as the creation of a PDU session initiated by the upper layer in idle mode) is shown in Figure 1:

11. The network access request sent.

It should be noted that after the NAS layer receives the network access request sent by the upper-layer application, the NAS layer determines the network access request from the configuration information of the terminal configuration according to the mapping relationship between different access requests and terminal configurations. Corresponding request category and set one or more request identifiers.

It should be noted that after the NAS layer receives the network access request, the NAS sends the network access request to the AS layer.

It should also be noted that the network access request sent by the NAS to the AS layer may specifically be a NAS signaling link establishment request.

It should also be noted that the NAS signaling link establishment request may be signaling generated by the NAS layer after the NAS layer receives the network access request.

It should be noted that the NAS signaling link establishment request sent by the NAS layer to the AS layer carries the request type and the request identifier.

After the AS layer receives the NAS signaling connection establishment request sent by the NAS layer, the AS layer can determine whether it can send a network access request to the network side.

The AS layer can check the access control of the network access request in the following order according to the requirements of the unified access control section of 3GPP TS38.311.

12. Send blocking parameters, which include blocking time.

In the embodiment of the present application, the network side may send the blocking parameter to the AS layer before the NAS layer sends the network access request to the AS layer; the network side may send the first network access request to the AS layer after the NAS layer sends the first network access request to the AS layer. The layer sends the blocking parameter, which may be determined according to the actual situation, which is not limited in this embodiment of the present application.

It should be noted that the blocking parameter also includes a set of blocking factors.

13. Determine that the network access request is prohibited.

The AS layer first checks the running status of the second timer in the AS layer. If the running status of the second timer is running, it is determined that the network access request is prohibited; if the running status of the second timer is not running, the AS The layer checks the request type and request identifier sent by the NAS layer according to the access control information in the system message SIB1 sent by the network side. Each request class has a corresponding set of blocking parameters. The AS layer first checks the request identifiers. If the blocking parameter corresponding to one of the request identifiers is 0, the access is allowed, that is, the network access request can be sent to the network side. If both are 1, the blocking check of the request type is performed again. If the random number generated by the AS layer is smaller than the blocking factor in the blocking parameter set, the access is allowed, that is, a network access request can be sent to the network side. On the contrary, it is determined that the network access request is prohibited.

14. Sending the information that the network access request is prohibited.

The AS layer sends the network access request prohibited information to the upper-layer application through the NAS layer.

15. Determine the running time of the second timer according to the blocking time, and start the second timer.

If the network access request is prohibited, the AS notifies the NAS layer that the network access request is prohibited, and starts a second timer. The running duration of the second timer is (0.7+0.6*rand)*blocking time, where rand is 0 A random number between -1, the blocking time is the access prohibition time in SIB1.

During the running time of the second timer, all access requests of the same request category as the network access request are prohibited.

16. Send a request mitigation message.

In the case that the second timer expires or is stopped for other reasons, the AS sends a request mitigation message to the NAS. The NAS layer forwards the request mitigation message to the upper layer, and the upper layer application decides whether to continue to initiate a network access request.

The network access request initiated by the terminal is judged at the NAS layer and the AS layer, and it is determined that the network access request is prohibited due to the unified access control mechanism, that is, the AS starts the second timer corresponding to the access type. During the running time of the timer, the terminal cannot make the same access attempt, until the second timer runs out of time or stops running, the AS layer generates a mitigation notification, and the terminal can send an RRC connection establishment request to the base station. .

However, for the application layer, when the user triggers the network access request is uncertain, so even if the terminal receives the mitigation notification, the terminal cannot immediately initiate the network access request, and requests to send the RRC connection establishment request to the base station. This will bring about a problem: when there is another network access request, do the NAS layer and the AS layer still need to perform unified access control check on the network access request? If a unified access control check is required, the problem is that the access request may be banned again after a judgment, and the access can be initiated again only after a second timer. The success rate of establishing an RRC connection between base stations reduces the user experience. If the unified access control check is not required, the original intention of the unified access control mechanism will be violated, the network burden on the base station side will be increased, and network congestion will occur on the base station side.

The problems existing in the prior art can be specifically solved by the methods in the following embodiments.

In this process, if the time length of the first running duration is too short, the first timer loses its meaning and cannot achieve the effect of improving the speed of the terminal sending a network access request to the network side. If the duration is too long, it cannot meet the requirements of unified access control, so the duration of the first running duration is an important parameter.

In this embodiment of the present application, the running duration of the second timer can be determined according to formula (1), that is, the request prohibition duration is obtained.

(0.7+0.6*random number)*blocking time (1)
