[0023] Next, in conjunction with the accompanying drawings, the access control method, device and terminal provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0024] As Figure 2 shown, an access control method provided by an embodiment of the present application includes:

[0025] Step 201, when the non-access stratum NAS of the terminal determines to reject the paging of the radio access network RAN, determine the relevant parameters of the general access control UAC process as downlink MT access.

[0026] Optionally, if the terminal is a multi-SIM terminal and is in the 5GS Mobility Management Connected mode with an RRC inactive indication, when receiving RAN paging from the lower layers, it may initiate a Service Request procedure and may carry an Information Element (IE) of the UE request type in the service request. The request type may be set to NAS signalling connection release.

[0027] When performing the UAC process, the NAS of the UE determines the relevant parameters of the UAC process as downlink MT access. Among them, determining the relevant parameters of the UAC process as MT access may indicate that the service request is a response to network paging, thereby reducing the probability that the service request for the terminal to reject RAN paging is rejected.

[0028] Optionally, the relevant parameters of the UAC process may include: access category and / or Radio Resource Control (RRC) establishment cause. The access category may indicate the access category of the service request for the terminal to reject RAN paging, and the RRC establishment cause may indicate the establishment cause of the RRC connection corresponding to the service request for the terminal to reject RAN paging. Then, determining the relevant parameters of the Universal Access Control (UAC) process as downlink MT access includes at least one of the following:

[0029] (1) Determining the access category as MT access. That is, determining the access category as access category 0 (=MT_acc), i.e., MT access.

[0030] (2) Determining the RRC establishment cause as MT access. That is, determining the RRC establishment cause as MT access (mt-Access).

[0031] As an optional embodiment, the method may further include: when the terminal determines to reject the RAN paging, generating a service request message in response to the RAN paging, where the service request message carries a terminal request type, and the terminal request type is set to: non-access stratum NAS signalling connection release; wherein, the access category indicates the access category corresponding to the service request message, and the RRC establishment cause indicates the RRC establishment cause corresponding to the service request message.

[0032] In this embodiment, when the UE NAS determines to reject the RAN paging, it initiates a service request procedure. Specifically, the UE NAS generates a Service Request message, carrying the UE request type IE, and the Request type is set to "NAS signalling connection release".

[0033] Optionally, the method further includes: setting the service type corresponding to the service request message to: MT service.

[0034] In this embodiment, when the terminal decides to reject the RAN paging, the request type of the generated service request message is NAS signalling connection release, and the service type is set to MT service. In the prior art, when the UE rejects the RAN paging, the Request type is set to "NAS signalling connection release", and the Service type is set to "signaling". In the embodiment of the present application, when the terminal decides to reject the RAN paging, setting the Service type to "MT service" can indicate that the service request procedure initiated by the terminal is a service in response to the RAN paging, and can reduce the probability that the access attempt to reject the RAN paging by the terminal is rejected.

[0035] When performing the UAC procedure, the UE NAS determines the access category as MT access and the RRC establishment cause as MT access. Optionally, the method further includes: the NAS of the terminal sends the relevant parameters of the UAC procedure to the lower layers; the lower layers perform an access control check on the terminal request according to the relevant parameters. Optionally, the lower layers may be the AS layer, such as: the Packet Data Convergence Protocol (PDCP) layer, the RRC layer, the Medium Access Control (MAC) layer, the Radio Link Control (RLC) layer, etc., which are not limited herein.

[0036] The UE NAS provides the access category and / or the RRC establishment cause to the lower layers. Optionally, it may also provide access identities to the lower layers, enabling the lower layers to perform an access control check based on parameters such as the access category, the RRC establishment cause, and the access identities, and then determine whether the service request for the UE NAS to reject the RAN paging is allowed. Optionally, the method further includes: when the result of the access control check indicates that the terminal request is allowed, sending the service request message.

[0037] Optionally, when performing the access control check, the lower layers determine whether each set parameter matches the terminal request. For example, a mapping relationship between the terminal's service request and each relevant parameter of the UAC may be preset in advance, and it is determined whether each parameter of the UAC procedure set by the NAS matches the service request initiated by the UE according to the mapping relationship. If they match, it indicates that the check passes and the UE is allowed to send the service request message.

[0038] As an optional embodiment, before determining to reject the Radio Access Network (RAN) paging, the method further includes:

[0039] The Access Stratum (AS) of the terminal receives the RAN paging message; the AS determines the paging-related information according to the RAN paging message; the AS sends the paging-related information to the NAS; the NAS determines whether to accept the RAN paging or reject the RAN paging according to the paging-related information.

[0040] Optionally, the paging-related information includes at least one of the following:

[0041] A paging indication message;

[0042] A paging cause.

[0043] In this embodiment, the paging indication message can be used to notify the NAS of the relevant information of paging. When the network pages the terminal due to an MT service, the base station of the network sends a RAN paging message to the terminal, and the RAN paging message may include a paging cause. After the UE AS layer receives the RAN paging message, it determines the paging indication message and / or the paging cause according to the RAN paging message, and sends the determined paging indication message and / or the paging cause to the NAS layer. The NAS layer decides whether to receive the RAN paging according to the received paging indication message and / or the paging cause.

[0044] It should be noted that the paging-related information may include a paging indication message and / or a paging cause, and may also include other paging-related information determined by the AS according to the RAN paging message, so that the NAS layer can determine whether to accept the RAN paging according to the paging-related information. The other paging-related information is, for example, a radio network temporary identifier, which is not limited herein.

[0045] If the parameter setting logic for other application scenarios in the existing protocol is followed, when the terminal determines to reject the RAN paging, parameters such as the access category and the RRC establishment cause should also be set to: uplink (Mobile Original, MO) access, and the Service type should be set to "signaling". However, this does not conform to the behavior of the service request initiated by the terminal in response to paging in the embodiment of the present application. Therefore, the probability that the access attempt of the terminal to respond to the RAN paging (i.e., the service request procedure initiated by the terminal) is rejected may increase. In the case where the terminal determines to reject the RAN paging in the present application, when the UE NAS performs the UAC process, the relevant parameters of the UAC are determined as MT access, and the Service type is set to "MT service", which can indicate that the service request procedure initiated by the terminal is a service request in response to paging, and can reduce the probability that the access attempt of the terminal to reject the RAN paging is rejected.

[0046] Optionally, the access control method provided by the embodiments of the present application can be applied to scenarios where a multi-card terminal (Multi-USIM, MUSIM) or a non-multi-card terminal rejects RAN paging. For example, for a multi-card terminal including two Universal Subscriber Identity Module (USIM) cards: USIM A and USIM B, if the terminal is currently communicating with the network corresponding to USIM A and receives an RAN paging from the network corresponding to USIM B, the terminal can decide to reject the RAN paging from the network of USIM B and determine the relevant parameters of the UAC process as MT access.

[0047] The following uses specific embodiments to illustrate the implementation process of the access control method of the embodiments of the present application.

[0048] Taking the terminal as a MUSIM as an example, it includes two USIM cards, namely USIM A and USIM B, corresponding to UE A and UEB.

[0049] Step 1: When UE A is communicating with Network A, UE B is in the 5GMM-CONNECTED mode with RRC inactive state.

[0050] Step 2: Since Network B pages UE B due to MT service, the base station of Network B sends an RAN paging to the UE, and the Paging message may include a paging cause.

[0051] Step 3: The AS layer of the UE receives the RAN paging and determines a paging indication message and / or a paging cause based on the RAN paging.

[0052] Step 4: The AS notifies the NAS that it has received the RAN paging (for example, by sending the paging indication message) and provides the received paging cause.

[0053] Step 5: The UE NAS decides whether to accept the RAN paging according to the received RAN paging indication message or paging cause. Among them, the paging cause can be voice or non-voice.

[0054] Step 6: According to Step 5, if the UE NAS determines to accept the RAN paging, it resumes the RRC connection and receives the data cached in the RAN.

[0055] If the UE NAS determines to reject the RAN paging, the UE can perform the following steps:

[0056] 1) Generate a service request message in response to the RAN paging, carrying the UE request type IE, and set the Request type to "NAS signalling connection release";

[0057] 2) Set the service type corresponding to the service request message to: MT services.

[0058] 3) Determine the access category as access category 0, i.e., MT access; and / or, determine the RRC establishment cause as MT access;

[0059] 4) Send parameters such as the access category, RRC establishment cause, and access identities to the lower layers, and the lower layers perform an access control check on the service request.

[0060] Step 7: If the lower layers perform an access control check on the service request and determine that this access attempt is allowed, then allow the UE to send the service request message.

[0061] In the embodiments of this application, when the UE NAS determines to reject the RAN paging, the access type corresponding to this service request initiated by the terminal is "reject RAN paging through 3GPP". As shown in Table 1, for example, when the access type in the attempted access is to reject RAN paging through 3GPP, the access category is set to 0, i.e., MT access.
