Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] In the paging process, the more cells the TA includes, the greater the probability of paging success, and the lower the frequency of initiating TAU, but the downlink overhead generated by sending paging messages also increases accordingly. Conversely, the less the number of cells included in the TA, the higher the frequency of initiating TAU, and the corresponding frequent execution of TAU will increase the system overhead. Then, in the paging process, it is...

Abstract

The invention discloses a paging method and device, and relates to the technology field of communication. When paging message is sent to UE at the network side, paging resource is saved, and paging efficiency is improved. In one embodiment, when a serving cell identifying that the statistical time is greater than or equal to a preset value in a preset time is acquired, an identity of a prior paging cell is acquired according to the serving cell identity, then the prior paging cell is acquired according to the identity of the prior paging cell, further paging message is acquired according to the prior paging cell, and the paging message is sent to the prior paging cells. The technical scheme is mainly applied in the paging process.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a paging method and device. Background technique [0002] Currently, the network side searches for user equipment (User Equipment, UE) by means of paging. Specifically, the network side divides an area within a certain range into several tracking areas (Tracking Area, TA), each TA is identified by a tracking area identity (Tracking Area Identity, TAI), and a TA contains one or more district. The UE will camp on one or more TAs according to its location. In this way, when the network side initiates paging, it needs to send a paging message to all cells in the TA; when the location of the UE changes and the TA it resides on changes, the UE needs to initiate a Tracking Area Update (TAU). [0003] The tracking area list TA list contains one or more TAs, and TAs contain multiple cells, and at the current moment or during the paging time, the UE location will not chan...
