Method and device for adjusting cell handover parameters

Abstract

Embodiments of the present invention provide a method and device for adjusting cell handover parameters. The method includes: determining the cell where the cell handover parameter needs to be adjusted among the source cell where the user is located and the target cell corresponding to the source cell, and obtaining The handover type corresponding to the handover event generated when switching between the target cells; obtaining the handover failure rate corresponding to each handover type, and determining the maximum handover failure rate among all the handover failure rates obtained; according to the handover type and The correspondence between the cell handover parameters determines the cell handover parameters corresponding to the handover type with the largest handover failure rate; adjusts the queried cell handover parameters for the determined cells that need to adjust the cell handover parameters. Through this method, the base station determines the cell handover parameters that need to be adjusted according to the handover type of the user between the cells, and improves the accuracy of adjusting the cell handover parameters.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell handover parameter adjustment method and device. Background technique [0002] In the wireless communication system, in the process of macro base station deployment, whether it is the initial station survey and construction, as well as the subsequent parameter optimization, it is to provide better coverage for mobile terminals in the entire geographical range. Even so, In the process of site deployment and parameter adjustment, it is impossible to plan well and set parameters for all scenarios. Therefore, there will be coverage blind spots or overlapping coverage of multiple base stations. Handover failures are more likely to occur in coverage blind spots and overlapping coverage areas of multiple base stations. In addition, in the coverage of dense urban areas, due to the large number of high-rise buildings, thick blocking walls and unique channel charact...

Problems solved by technology

When the above two coverage situations occur, handover failure is very likely to occur. At this time, the corresponding cell handover parameters need to be adjusted. The cell handover parameters may be cell independent offset, hysteresis parameters, trigger events, etc.

[0005] The existing cell handover parameter adjustment strategies are mainly aimed at the ping-pong handover situation, or directly adjust the cell handover parameters in general, which leads to poor accuracy in adjusting the cell handover parameters, and handover failure is likely to occur
