Abstract

The invention discloses a method for optimizing network coverage and capacity, which comprises that: a base station judges whether the acquired coverage and capacity optimization data are normal and determines whether coverage and capacity problems exist; and if existing, the base station determines a resolution strategy according to the existing coverage and capacity problems and the coverage and capacity optimization data causing the problems. The method finishes an optimization process through the base station, realizes automatic optimization of network coverage and capacity, saves a large amount of manpower and material resources required by the traditional optimization method, reduces the network operation and maintenance costs, can effectively make up missed matching and mismatching phenomena of parameters in network planning in dynamic network variation at the same time, effectively compensates and optimizes the network coverage and capacity, improves the network performance, reduces the service dropped call rate, and totally improves the satisfaction of users.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method and system for optimizing network coverage and capacity. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system consists of E-UTRAN (UMTS Terrestrial Radio Access Network, UMTS radio access network) and evolved packet core (Evolved Packet Core, EPC) network, where E-UTRAN includes and EPC through the S1 interface A collection of connected eNBs (Evolved NodeB, evolved Node B), the eNBs can be connected through X2, and the S1 and X2 interfaces are logical interfaces. One EPC can manage one or more eNBs, one eNB can also be controlled by multiple EPCs, and one eNB can manage one or more cells. The LTE-A system evolved from the LTE system. The network architecture is consistent with LTE. In LTE-A, some technologies such as relay (relay), spectrum aggregation and Coordinated Multipoint transmission reception (Coordinated Multipoint transmissio...
