System message 1 label value distributing method

Abstract

The method suitable to broad band CDMA system includes following steps: operation and maintenance center completes configuration of label value range of system message 1 corresponding to location area code and routing area code, and the configuration is sent to database at background for conservation; in procedure for creating subzone, foreground sends message to database at background based on subzone id so as to obtain label value range of system message 1 corresponding to location area code and routing area code for the subzone, and sends to base station through request message of system message updating, and is broadcasted through base station in subzone. Network planning guarantees that label value range of system message 1 is identical in subzones in same LAC or inside RAC, and label value range of system message 1 is not identical in adjacent subzones in different LAC or RAC.

Description

technical field [0001] The invention relates to the technical field of code division multiple access mobile communication, in particular to the technical field of cell parameter configuration. technical background [0002] Code Division Multiple Access (CDMA) is a spread spectrum mobile communication technology. Spread spectrum communication technology was mainly used in military communication in the early stage, and it will also be widely used in civilian communication due to its excellent performance. Now there are already commercial CDMA cellular mobile communication systems running in the telecommunication network. [0003] To increase the capacity of mobile communication systems, cellular systems are commonly used. In a cellular mobile communication system, the entire network is composed of several cells, and different cells have different configuration attributes, such as the PLMN area to which the cell belongs, the available channel types of the cell, and so on.

Problems solved by technology

The disadvantages of this technique are obvious. First, the average allocation for each cell may cause adjacent cells with different LAC or RAC to have the same label value, so that when the UE reselects from one of the cells to After another cell, it is found that the label value of the system message 1 of the two cells is the same, so it will not read the content of the system message 1, and does not know that the LAC or RAC has been replaced, and the CN will not know that the UE has The location is changed, which will cause the CN to be unable to page the UE

Second, when two cells have the same LAC or RAC, and the parameters of other system message 1 are also the same, then using this scheme may cause the two cells to have different label values

This will cause the UE to re-read the content of the system message 1 when it moves from one cell to another, which will cause unnecessary waste of time and increase the power consumption of the UE

Third, for the same cell, when the other content in system information 1 is updated, due to the use of this random method, it is likely to cause the same label value twice before and after, so that the resident in this cell The UE in the cell thinks that the content of the system information 1 has not been updated, and will not read the content of the new system information 1

For the UE, there will still be no location or route update

Second, for several cells with different LAC or RAC, if for some reason, the system message 1 of one of the cells is frequently updated (of course this is an extreme situation, but there is also this risk ), then the tag value of system message 1 of this cell may be the same as the tag value of system message 1 of other cells if it is updated for a cycle

This will still cause the UE to move in different LAC or RAC cells without sending location updates and routing area updates
