Method, system and relevant equipment for updating neighboring area list

Abstract

The embodiment of the invention relates to the communication field, and discloses a method for updating a neighbor cell list, as well as a system and a related device thereof. A base station controller adds a determined cell which is adjacent to a newly added Femto cell as a main cell, a newly added Femto cell is the neighbor cell list of the neighbor cell; a neighbor cell list of the Femto cell is added in the neighbor cell to complement the neighbor cell list which is reselected and switched from the cell in the direction. A mobile terminal in the neighbor cell can conveniently monitor and select the Femto cell as a candidate cell for reselection at idle time and for switching at connection state.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, system and related equipment for updating a neighboring cell list. Background technique [0002] In the wireless communication system, there are not only macro cells for wide coverage, micro cells for coverage in hotspot areas with dense traffic / throughput, but also pico base stations with smaller coverage. Such as: femto cell. This type of pico base station is mainly used in homes, and of course it can also be used in schools, shopping malls, office buildings and other places. The uplink is connected to the IP network, and the downlink follows the standard air interface protocol, such as supporting CDMA20001X (code division multiple access communication technology intervening between the second generation and the third generation) or CDMA20001X EVDO (enhanced code division multiple access communication technology) space interface protocol, etc. Take a femto cell fo...

Problems solved by technology

[0015] There are two disadvantages in this technical solution: first, when the base station controller creates the neighbor cell list, it only creates a neighbor cell list with the Femto cell as the main cell and its adjacent cells as the Each cell is the primary cell, and newly added to the neighbor list of neighboring cells including Femto cells, which is not convenient for mobile terminals to conveniently monitor and select Femto cells as idle reselection and connected state switching when they are in neighboring cells. candidate cell

Second, when the base station controller creates a neighbor cell list in which the adjacent base station is the primary cell and the Femto cell is added as the neighbor cell, since the uplink and downlink frequencies of the FDD system are different, the uplink and downlink losses are different, so It is inaccurate to use the situation of adjacent cells detected by Femto cell in the prior art as the method of creating a neighbor list with Femto cell as the primary cell and adjacent cells as adjacent cells
