Problems solved by technology

Under the architecture where the base station is separated into centralized network elements and distributed network elements, there is no process and method for CAG connection mobility management when the UE is dual-connected to the base station. In addition, when the UE is dual-connected to the base station, the Xn On the interface, there is no process and method for how the core network verifies UE's CAG membership

Embodiment 1

[0050] In this embodiment, a cell handover method is provided, which is applied to the main base station, figure 1 It is a flow chart (1) of a cell handover method according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0051] S102. Receive the measurement report uploaded by the user UE, and send a request message to the target network element in response to the measurement report, where the request message is used to instruct the target network element to establish UE context;

[0052] S104. Handover the UE to the target cell corresponding to the target network element according to the UE context.

[0053] It should be further explained that, the above S102 and S104 are executed by the master base station, but are not limited thereto.

[0054] It should be further explained that, the specific type of the above request message may be an Xn interface message or an X2 interface message.

[0055] In an optional ...

Embodiment 2

[0164] In this embodiment, a cell handover method is provided, which is applied to the user side, Figure 7 It is a flow chart (2) of a cell switching method according to an embodiment of the present invention, such as Figure 7 As shown, the process includes the following steps:

[0165] S202. Send a measurement report to the main base station, where the measurement report is used to instruct the main base station to send a request message to the target network element in response to the measurement report, and the request message is used to instruct the target network element to establish a UE context;

[0166] S204. Handover the UE to the target cell corresponding to the target network element according to the UE context.

[0167] It should be further explained that, the execution subject of the above steps S202 and S204 is the user, but is not limited thereto.

[0168] In an optional embodiment, the request message includes at least one of the following:

[0169] The se...

Embodiment 3

[0190] In this embodiment, a user processing method is provided, which is applied to the base station side, Figure 8 is a flow chart (1) of a user processing method according to an embodiment of the present invention, such as Figure 8 As shown, the process includes the following steps:

[0191] S302. Receive an NG interface signaling UE text modification request message sent by the core network, where the NG interface signaling UE text modification request message carries at least one of the following: UE's CAG membership status, cause value, and expiration indication;

[0192] Wherein, the expiration indication is used to indicate that the CAG membership of the cell corresponding to the primary base station and / or the secondary base station expires.

[0193] It should be further explained that, the execution subject of the above step S302 is the base station, but it is not limited thereto.

[0194] In an optional embodiment, after receiving the NG interface signaling UE t...

Abstract

The invention provides a cell switching method and device, and a user processing method and device. Specifically, the cell switching method comprises: receiving a measurement report uploaded by a userUE, and sending a request message to a target network element in response to the measurement report, the request message being used for indicating the target network element to establish a UE text; and switching the UE to a target cell corresponding to the target network element according to the UE text. According to the invention, the problem of CAG connection management in mobility in dual connection of the UE and the base station is solved, and the beneficial effect of improving the CAG connection management in mobility in dual connection of the UE and the base station is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching method and device, and a user processing method and device. Background technique [0002] Non-public network NPN (non-public networks) means that one or more cell access users in the mobile communication network are restricted and conditional, while ordinary cells can allow all legal subscribers of operators (and roaming) user) access. The NPN network can use the concept of CAG (Closed Access Group) for access control. CAG refers to a group of subscribers who are allowed to access one or more specific cells, and the same user can belong to multiple CAGs. A CAG is identified by a CAG ID, and a UE (User Equipment, user equipment) maintains a CAG ID list (allowed CAG ID list) of the CAG to which it belongs, and the CAG cells contained in other CAG IDs outside this list are for the UE language is not accessible. And each CAG cell broadcasts a CAG ID, and members ...
