Cell optimization method, device and system in mobile communication system

Abstract

Disclosed is a method for optimizing cells comprising: obtain Key Performance Indicators (KPI) of Mobility Robustness Optimization (MRO) and Mobility Load Balancing (MLB) of the managed cells; select the cell that the united performance indicator of MRO and MLB is the worst as the cell to be optimized, and select the terminal to be handed over from the handover domain of the cell to be optimized, and determine the adjacent cells to be optimized; obtain the handover offset between a pair of cells, the offset enables the terminal to be handed over to satisfy an A3 event, and enables the KPI of MRO of the cell to be optimized to be lower than the preset value; assign the handover offset between a pair of cells to the terminal to be handed over for finishing the handover. Correspondingly, disclosed are a communication system and a device for optimizing cell. The above technical solutions performing united optimization for the cell with the worst performance and for the corresponding adjacent cells, based on the statistics of the key united performance indicator of the cells, realize the load balancing of the cells, at the same time, and reduce as far as possible the ping-pong handover, thus reducing efficiently the performance conflict between MRO and MLB, and enhancing the user experience.

Description

technical field [0001] The invention relates to the communication field, in particular to a cell optimization method, device and system in a mobile communication system. Background technique [0002] In the current wireless network, due to the coexistence of different networks, the network becomes more and more complex, a large number of wireless parameters and data greatly increase the workload of network optimization personnel, and operators hope to reduce operating costs and manual intervention, so in this In the background, the SON (self organizing network, self-organizing network) characteristic of LTE is regarded as an important research direction of 3GPP. SON is a concept proposed by mobile operators during the standardization stage of LTE networks. Its main idea is to realize some self-configuration and self-optimization functions of wireless networks, reduce manual participation, and reduce operating costs. In the SON technology, mobility robust optimization (MRO, ...

Problems solved by technology

The existing technical solution does not fundamentally solve the problem of the conflict between MRO and MLB functions, but only blocks or closes one of the functions when MRO and MLB conflict, resulting in a decline in user satisfaction
