Problems solved by technology

[0006] The disadvantage of the prior art is: in an area where location updates are frequent (such as an area bordering different LAs), if the mobile terminal is updating its location, using the TMSI local paging method in the LA will cause paging failure because the mobile terminal is already in the LA. Another LA registers and camps. If the global paging of all cells in the MSC is used, the paging success rate will be improved, but the paging burden of the communication network will be increased, especially when there are many LAs under an MSC, the global paging very inefficient
In addition, although global paging will improve the paging success rate, it will increase the access delay and affect the call effect

Embodiment Construction

[0042] The present invention provides a method for establishing an extended location area, as shown in Figure 1, the steps for establishing an extended location area are:

[0043] Step (101), base station controller sends the LA of configuration order configuration cell to mobile communication network database; Have cell ID and LAC in the command, set up the cell list of LA in the database, in the cell list of setting up, cell ID and LAC Set to the associated state, LA is one of the attributes of the cell, and cells with the same LAC are considered to belong to the same LA;

[0044] Among them, LA is a collection of a group of cells, and a list of cells is stored in the communication network database to represent the cells belonging to the same LA; exLA (extend-LA, extended location area) is added on the basis of the cell list contained in the traditional LA Some cells are established, and exLA is divided by exLAC (extend-Location Area Code, extended location area code) in the...

Abstract

The method comprises: the base station controller (BSC) sends a configuration command used for configuring the location area (LA) of cell to the mobile communication network database, and builds a list of cells in the LA; BSC sends a configuration command used for configuring the expanded cells in the LA to the mobile communication network database, and adds the expanded cell to the list of cells in LA saved in the database; the cells and expanded cell in LA composes an expanded LA; the expanded LA is partitioned in mobile communication network by using the expanded LA number. The invention also reveals a paging method based on the expanded LA, which comprises: the core network sends paging command to BSC; after receiving the paging command, according to the information in the command, BSC prepares the list of paging cells; based on the expanded LA, BSC sends paging message; after receiving the paging message, mobile terminal returns the response message to the BSC.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for establishing an extended location area in mobile communication and paging based on the extended location area. Background technique [0002] LA (Location Area, location area) is an important concept in mobile communication, which is a collection of a group of cells, and is an important part of mobile management of mobile terminals. The entire mobile communication network is divided into different service areas by LAC (Location Area Code, Location Area Code), and the network side paging the mobile terminal by sending a paging message in the location area. [0003] The function of the location area is described as follows: To establish a call connection with a mobile terminal, the network side must record the location information of the mobile terminal at any time, so that the terminal can be paged when needed. The basic information of the locally registered user a...
