Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wireless communication, and particularly relates to a terminal registration method, a terminal and a network side device. BACKGROUND

[0002] When a disaster (e.g., a fire) occurs in a public land mobile network (PLMN), the PLMN can not be able to continue to provide services for a user equipment (UE, also referred to as a terminal). In order to reduce the impact on the UE, if there is another PLMN ready to provide services (such as voice calls and / or mobile data services, etc.) for the UE, the UE can obtain services from the other PLMN when the disaster occurs, so that service interruption is minimized.

[0003] In a non-disaster scenario (i.e., a scenario in which the service PLMN of the UE does not cause the terminal to be unable to provide services due to a disaster), the UE is not allowed to access a forbidden PLMN. However, in order to avoid the UE being unable to obtain service in a disaster scenario and improve the service experience of users, especially for those UEs with emergency service forwarding, the 3GPP system needs to provide a way for the UE to register to the forbidden PLMN of the UE to minimize service interruption of the UE. However, the premise of accessing the forbidden PLMN is that the service PLMN of the UE has DC, and the UE cannot find an allowed PLMN.

[0004] However, for the following scenario:

[0005] PLMN A is a forbidden PLMN of the UE, but has not been added to the forbidden PLMN list of the UE;

[0006] The PLMN D providing services for the UE has DC;

[0007] PLMN A is able to provide DC services for PLMN D when DC occurs.

[0008] Since PLMN A has not been added to the forbidden PLMN list of the UE, the UE considers PLMN A as an allowed PLMN of the UE, and performs selection and registration. When the UE registers to PLMN A, it does not carry any registration information about the DC scenario.

[0009] For this case, the PLMN A processing manner is to reject the registration request of the UE (because the PLMN A is the forbidden PLMN of the UE), then the UE needs to add the PLMN A into the forbidden PLMN list of the UE, and further perform the selection and registration of the PLMN A in the DC scenario, which obviously increases the signaling overhead of the UE and the PLMN A.

[0045] The terminal registration method, the terminal, and the network side device provided by the embodiments of the present application are described in detail below in combination with the accompanying drawings and some embodiments and application scenarios.

[0046] The solution idea of the terminal registration method in the embodiments of the present application is as follows: When the terminal's forbidden network has known that the network currently serving the terminal has a DC case, after receiving the registration request sent by the terminal, the terminal's registration process should be performed instead of being directly rejected, and the terminal is instructed that the forbidden network is a network providing DC service for the terminal's serving network.

[0047] That is, the precondition of the terminal registration method in the embodiments of the present application is:

[0048] 1) The network PLMN A that the terminal sends a registration request to is a forbidden network of the UE, but has not been added to the forbidden network list of the terminal; when the serving network PLMN D of the terminal has DC, since the PLMN A has not been added to the forbidden network list of the terminal, the terminal considers the PLMN A as an allowed network of the terminal, preferentially selects the PLMN A, and initiates a registration process to the PLMN A:

[0049] 2) The PLMN D does not have DC, and provides service for the terminal;

[0050] 3) There is a DC service roaming agreement between the PLMN A and the PLMN D, that is, when the PLMN D has DC, the PLMN A can provide DC service for the terminal served by the PLMN D.

[0051] Please refer to Figure 2 The embodiment of the present application provides a terminal registration method, comprising:

[0052] Step 21: If the first network that provides service for the terminal has DC, the terminal selects a second network, and sends registration request information to the second network, wherein the second network is not in the forbidden network list of the terminal.

[0053] The first network and the second network in the embodiment of the present application can be PLMNs.

[0054] Step 22: The terminal receives registration acceptance information and DC service information sent by the second network, wherein the registration acceptance information is used for indicating that the registration request of the terminal is accepted, and the DC service information is used for indicating that the second network is a network that provides DC service for the first network.

That is, since the second network is not in the forbidden network list of the terminal, the terminal considers the second network as a network that allows registration, and therefore does not carry DC related information when sending the registration acceptance information to the second network.

That is, the registration acceptance message can carry the registration acceptance information and the DC service information. The configuration update command message is a non-access stratum (NAS) message.

[0068] In an implementation, the DC service information is carried by the configuration update command message.

[0069] In the embodiments of the present application, after the terminal receives the DC service information sent by the second network, the terminal further adds the second network to the forbidden network list according to the DC service information.

[0070] Optionally, before the terminal adds the second network into the forbidden network list, the terminal further receives DC release information, wherein the DC release information is used to indicate that the first network has released DC. The DC release message can be sent by the second network, that is, after receiving the DC release information sent by the second network, the terminal adds the second network into the forbidden network list.
