Problems solved by technology

[0005] In the process of realizing the present invention, the inventors of the present invention found that the prior art has at least the following technical defects: in the traditional 2G / 3G system network operation and maintenance process, the setting of switching parameters is very cumbersome and requires a lot of human resources. Therefore, under normal circumstances, the configuration of handover parameters is only carried out during the initial deployment of the base station, and there are generally few special adjustments thereafter.
Since the network communication environment changes rapidly, the frequency of manual adjustments cannot catch up with the speed of change, so it is impossible to completely avoid "Too Early / Late HO", "Unnecessary HO", Occurrence of adverse events such as "handover to a wrong target cell (HO to a Wrong Cell)"
The diversification of IMT-Advance LTE+ (Long Term Evolution) system network equipment also makes the handover problem more complicated, and traditional manual configuration alone cannot meet the needs of the network.

[0077] First explain a few concepts in this article:

[0078] The source cell refers to the serving cell of the current user terminal (UE);

[0079] The target cell refers to the cell to be handed over to when the UE leaves the source cell, and the target cell becomes the serving cell of the UE after the UE is handed over;

[0080] The new cell means that after the UE is handed over from the source cell to the target cell, because the signal of the target cell is poor, the UE reconnects to another cell due to call drop, and this other cell is called a new cell.

Abstract

The invention discloses a switching self-optimizing method for a mobile communication network. The method comprises the following steps of: periodically acquiring switching performance indexes such as dropped call rate, switching failure rate, ping-pong switching rate, congestion rate and the like of a switching region; judging whether a current switching problem is early switching, late switching, ping-pong switching or switching to a wrong cell according to the value of each acquired switching performance index; and adjusting switching parameters such as cell offset, trigger time and the like to automatically solve the switching problem, effectively control the phenomena of call drop, switching failure, ping-pong switching, switching to a wrong cell and the like in the switching process, increase the utilization ratio of a wireless resource and enhance the user service quality. According to the method, a large quantity of human resources consumed by the adjustment of the switching parameters can be effectively reduced, the operation cost is saved, and the operation efficiency is increased remarkably.

Description
