Embodiment

[0166] Example, refer to Figure 9 , an embodiment of the present invention provides a communication system, including: at least one base station (such as Figure 9 80 and 81 in) and network controller 90, wherein:

[0167] The base station is used to count the KPIs of the MRO and MLB of the cell;

[0168] The network controller 90 is configured to obtain the key performance indicators KPI of the mobility robust optimization MRO and the mobility load balancing MLB of each managed cell; Joint performance index; select the cell with the worst joint performance index as the cell to be optimized; select the terminal to be switched from the terminals located in the handover area, and the existence of the terminal to be switched makes the KPI of the MLB of the cell to be optimized higher than the preset The first threshold value is set; the handover area includes the overlapping area of ​​the cell to be optimized and each adjacent area of ​​the cell to be optimized; the adjacent a...

Abstract

An embodiment of the invention discloses a cell optimization method. The method comprises obtaining mobility robustness optimization (MRO) and mobility load balancing (MLB) key performance indicators (KPIs) of managed communities; selecting a cell with the poorest MRO and MLB combined performance indicator as a cell to be optimized, selecting a terminal to be switched from a switching region of the cell to be optimized, and determining an adjacent cell to be optimized; obtaining a relative switch offset of the cell enabling the terminal to be switched to meet an A3 event and an MRO KPI of the cell to be optimized to be lower than a preset value; and configuring the relative switch offset of the cell for the terminal to be switched. Correspondingly, an embodiment of the invention further discloses a cell optimization device and a communication system. By means of the technical scheme, the cell with the poorest performance and the corresponding adjacent cell are optimized integrally on the basis of calculation of the KPI, ping-pong switching is reduced to the greatest extent while cell load balance is achieved, and accordingly, conflicts of MRO and MLB performances are reduced effectively, and the user experience is improved.

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, ...
