Method and device for determining neighboring cell relationship

Abstract

The invention discloses a method for determining a neighboring cell relationship, which comprises the following steps of: acquiring attribute information of each cell, and determining a large region coverage range and a small region coverage range corresponding to each cell according to the attribute information; aiming at each cell, executing the following operations respectively: searching cells positioned in the large region coverage range and the small region coverage range corresponding to each cell, and further screening the cells meeting the requirements in the searched cells positioned in the large region coverage range; and taking the screened cells meeting the requirements and the searched cells positioned in the small region coverage range as neighboring cells of each cell, and establishing a neighboring relationship list of each cell. The invention discloses a device for determining the neighboring cell relationship at the same time. The method and the device are accurate and efficient, and do not increase the load of network elements such as a base station controller (BSC) and the like.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and device for determining neighbor relationship in a mobile communication system. Background technique [0002] In the existing mobile communication system, terminal handover occurs in many cases. For example, when a terminal enters the coverage area of ​​one cell from the coverage area of ​​another cell during a call, the base station will compare the signal strength and The bit error rate and other information are reported to the base station controller (BSC, BaseStation Controller), and the BSC judges whether the signal strength of the reported cell is better than the original cell where the terminal is located, and judges whether the reported cell is a neighboring cell of the original cell, That is, whether it is in the neighbor relationship list of the original cell, and if so, perform handover. [0003] It can be seen that the success of the handover lar...

Problems solved by technology

[0007] For method 1), since the work such as measurement needs to be completed by BSC, the load of BSC is increased, so this method can only be used when the load of BSC is light, and the real-time performance is poor; for method 2), although It will not increase the load of BSC, but because it is completely handled manually, it is less efficient and less accurate
