Configuration method for message label value of broad band CDMA system

Abstract

This invention discloses an allocation method for information label value of a WCDMA system, which distributes label values of different zones with different system parameters separately to enable UE to make system refreshment when moving among different zones with different system parameters and the label value conflict will not happen for the CELL new information which should be read, the UE does not repeat system refreshment when moving in this kind of zones by setting same label values for local areas with the same father so as to reduce cost of electricity by UE greatly.

Description

technical field [0001] The invention relates to an information identification technology in a wideband code division multiple access (WCDMA) system, in particular to a tag value configuration method for message 1 of the wideband code division multiple access system. Background technique [0002] According to the WCDMA protocol, the cell broadcast system information is transmitted by the cell broadcast system information block, and the system information block is divided into main message block (MIB), scheduling block (SB), system information block type 1 (SIB1), and System information block type 2 (SIB2), system information block type 3 (SIB3), etc., among which SIB1 mainly stores the information of the core network (CN) and the timer of the user equipment (UE), which contains information related to UE location update Information. Information blocks such as SIB1, SIB2, and SIB3 are logically transmitted separately, and the UE respectively determines whether the correspondin...

Problems solved by technology

[0008] This method of randomly assigning the SIB1 label value of each cell has obvious defects: First, it is likely to cause neighboring cells in different location areas (LACs) or routing areas (RACs) to have the same The tag value of SIB1 in the new cell, which will cause the UE to find that the tag value of SIB1 in the two cells is the same after moving from one cell to another cell, so the content of SIB1 in the new cell will not be read, but in fact the two cells In different LACs or RACs with different configuration attributes and system parameters, but the UE cannot confirm that the LAC or RAC has been replaced, and the CN will not know that the UE has changed locations, resulting in the adverse consequences that the CN cannot page the UE

[0012] This method also has defects: First, if each cell configures the SIB1 label value from a specific value when it is initially established, then after these cells are established, all SIB1 label values ​​are the same, if at this time Two adjacent cells are in different LACs or RACs, and there will still be situations where the UE moves from one cell in different LACs or RACs to another adjacent cell without performing location or routing updates

In this way, there will still be situations where the UE moves from one cell in different LACs or RACs to another adjacent cell without performing location or routing updates.
