Partition method, update method, apparatus and system for universal terrestrial radio access network registration area

Abstract

Embodiments of the invention provide a partition method, an update method, an apparatus and a system for a universal terrestrial radio access network registration area, and relate to the field of mobile communication technology. The update method for the universal terrestrial radio access network registration area comprises the steps of selecting optimization identification from a universal terrestrial radio access network registration area identification set of a current cell that user equipment is in, when update information for the universal terrestrial radio access network registration area sent by the user equipment is received or when the user equipment transfers from a non-universal terrestrial radio access network registration area paging access state to a universal terrestrial radio access network registration area paging access state. By arranging auxiliary optional ID for each cell in a base station as URA ID of an area adjacent to the area of the base station, the URA ID that the UE uses is the auxiliary optional ID arranged for the cell without updating the URA when the UE moves to a cell adjacent to but with different optimization ID from the current cell, so that updating of the URA is reduced and FACH channel jam can be prevented.

Description

technical field [0001] The present invention relates to the field of mobile communication technologies, and in particular to a method, device and system for dividing and updating a Universal Terrestrial Radio Access Network Registration Area (URA for short). Background technique [0002] The URA is the division of internal areas of a Universal Terrestrial Radio Access Network (abbreviated as "UTRAN"). A URA can contain one or several cells, and each URA is assigned a URA ID (URA Identify, referred to as "URA ID"), and each cell can be configured with 1 to 8 URA IDs (these URAs configured by the cell below IDs are known as URA ID sets), and these are usually planned by the network operator. [0003] When the user equipment (User Equipment, referred to as "UE") is in the UTRAN registration area paging access (URA Paging Channel, referred to as "URA_PCH") state, the UE belongs to a certain URA and can be accessed by the wireless network within the range of the URA. Controller...

Problems solved by technology

[0005] In the prior art, every time the UE moves to a new URA, it will update the URA immediately, so the URA update will be concentrated in the border area of ​​the URA; and, if the URA is too small during network planning, that is, the included If the number of cells is small, the update frequency of the URA will be high, resulting in congestion of the Forward Access Channel (FACH). If the URA is too large, that is, the number of cells included will make the URA When paging the UE in each cell, due to the large number of cells, too many paging messages are generated, resulting in congestion of the paging channel (PCH), both of which will cause system performance degradation
