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 c...

Embodiment Construction

[0040] Embodiments of the present invention provide a method, system and related equipment for updating a neighbor list. When a new Femto cell is added, the base station controller determines the cell that needs to update the neighbor list according to the received cell-related information; is the neighbor list of the neighbor cell; the base station controller sends the neighbor list to the base station of the cell that needs to update the neighbor list for storage; the base station to which the cell belongs broadcasts the neighbor list to All mobile terminals or only unicast to authorized mobile terminals. The adjacent cell refers to the original macro cell adjacent to the newly added Femto cell and the original Femto cell that is already working normally.

[0041] The method for updating the neighbor list provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

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...
