Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0031] Before introducing the embodiments of the present invention, first briefly introduce the nouns involved in the embodiments of the present invention:

[0032] Control plane node: responsible for UE connection management, security authentication, mobility management and location management. In a fourth generation (Forth Generation, 4G) network, the control plane node is a mobility management entity (Mobility Management Entity, MME). In a fifth generation (Fifth Generation, 5G) network, the control plane node is a control plane functional network element (Control Plane, CP).

[0033] User plane node: mainly responsible for forwarding service data. In a 4G network, the user plane node includes a serving gateway (Serving Gate...

Abstract

The invention discloses a tracking area list distribution method and device and belongs to the field of communication technology. The method disclosed by the invention comprises the following steps: receiving a request message from user equipment (UE), wherein the request message carries user identification and tracking area information of a position where the UE is located currently; acquiring user subscription information of the UE according to the user identification, wherein the user subscription information is at least used for indicating a data network or service signed by the UE, the data network comprises a local data network and a mobile data network; and based on the user subscription information and the tracking area information, distributing a tracking area list for the UE. Therefore, the signaling overhead problem caused by frequent initiation of a TAU process by the UE while moving can be avoided as far as possible.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a tracking area list allocation method and device. Background technique [0002] In a mobile data network, in order to be able to page a user equipment (UE) when it is in an idle state, the control plane node in the core network, which is mainly responsible for connection management and mobility management, can A tracking area list is allocated to the UE. After the UE stores the tracking area list, if it detects that the tracking area information of the area it is in is not stored in the tracking area list during the moving process, it initiates a tracking area update (Tracking Area Update, TAU) process to the control plane node to Requesting the control plane node to reallocate a tracking area list for the UE. [0003] In practical applications, operators generally divide and configure tracking area lists according to different division strategies. For e...
