Management method of neighborhood relation

Abstract

The invention discloses a management method of a neighborhood relation. In the method, a base station can find the problem of a distribution neglect neighborhood timely through periodical retrieval, and a terminal is triggered to search for the distribution neglect neighborhood, so that the distribution neglect neighborhood can be found and added timely, at the same time, the base station can realize timely discovery and deletion of a redundant neighborhood according to the switching measuring report of the terminal. By using the method provided by the invention, the neighborhood list of each cell can be effectively and dynamically managed and maintained, it is ensured that the neighborhood list of each cell adaptively changes with network topology, and the neighborhood list of each cell can be always maintained at an optimal state.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for managing neighbor cell relations. Background technique [0002] In order to meet the rapid increase in the number of users in the cellular mobile communication system and the substantial increase in user service requirements, the scale of the cellular network is constantly expanding, resulting in a situation where more and more base stations are deployed in the wireless network, and multiple The existing standard cellular communication systems coexist and continue to deepen their cooperation with each other. However, for operators, the management and maintenance of neighbor relationship between cells in the cellular network has become more and more cumbersome. Therefore, operators hope to replace traditional manual neighbor relationship management with automated neighbor relationship management, thereby reducing network overhead. O&M costs while improving network p...

However, the specific method for realizing ANRF is not directly given in the standard

Currently, there are many methods for realizing ANRF, such as automatic measurement and detection of adjacent cells by the base station, and selection of adjacent cells through handover performance statistics. However, these methods have two types of problems. One is that the terminal detects adjacent cells, but only Focusing on the discovery of missing cells, it is impossible to delete redundant adjacent cells in the adjacent cell list in a timely manner. The other type is to detect adjacent cells by the base station, but because the base station is different from the terminal, the location is fixed and located in the center of the cell, far from the ground Far away, resulting in poor measurement accuracy of the base station, which in turn affects the effectiveness of neighbor cell relationship maintenance
