Abstract

The invention provides a tracking area updating device, system and method. The method includes the following steps that: first information is obtained through using user equipment adopted as a tracking area updating device, wherein the first information is used for determining waiting time; if it is determined that a tracking area updating process is required to be carried out, a processing module determines the waiting time according to the first information; and after waiting for the waiting time, the user equipment sends a tracking area updating request message to a core network device which is adopted as a tracking area updating device. With the tracking area updating device, system and method adopted, as for user equipment which moves at a high speed, for example, UE which communicates in a high-speed railway scene, each UE is configured to wait for a certain time, and thereafter, carry out a tracking area updating process, and therefore, signaling storm caused by a situation that a certain number of UE intensively trigger tracking area updating processes in a short time can be avoided, and network congestion can be avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a tracking area update device, system and method. Background technique [0002] In the existing standard, the user equipment (User Equipment, referred to as: UE) will initiate an attach process to the network when it is powered on. figure 1 Attachment (attach) flowchart schematic diagram provided for the prior art, refer to figure 1 , in the attach process, the UE and the Mobility Management Entity (MME for short) need to perform the interaction process of Attach Request (AttachRequest) / Attach Confirmation (AttachAccept) / Attach Complete (AttachComplete). The TrackingAreaIdentity (TAI for short) list is given to the UE. When the UE is in the idle state and the MME needs to page the UE, it sends a paging message to the UE based on the TAI list information. Generally, all TAIs included in the TAI list and all cells included in each TAI must send paging messa...
