Abstract

The invention relates to intelligent analysis and intelligent optimization of an LTE mobile communication system. The problem that the coverage relation, the switching relation and the interference relation among cells cannot be accurately quantified and analyzed in an existing LTE system is solved, the problem that the degree of intelligence and the degree of automation are low in an PCI optimization method of the existing LTE system is also solved, and a relation matrix establishment system and method and a PCI intelligent optimization system and method are provided. According to the technical scheme, the relation matrix establishment system is formed by the way that an MR data processing module is connected with an LTE system body, and a CIM cell relation matrix module is connected with the MR data processing module; the PCI intelligent optimization system is formed by the way that a PCI intelligent optimization module is connected with the CIM cell relation matrix module in the cell relation matrix establishment system. The relation matrix establishment system and method and the PCI intelligent optimization system and method have the advantages of being capable of not only quantifying the inference relation among the cells, but also planning and optimizing PCI setting of the cells, suitable for LTE system analysis and wireless optimization and also suitable for 4G service providers to improve operation efficiency.

Description

technical field [0001] The present invention relates to the network optimization of the LTE mobile communication system, in particular to the application of measurement reports (MR, Measurement Reports) in the LTE mobile communication system and the planning and optimization of the Physical Cell Identifier (PCI, Physical Cell Identifier). Background technique [0002] In the existing LTE (Long Term Evolution) mobile communication system, the following two coverage, handover and interference relationship analysis methods are generally used: [0003] 1. Analysis method of coverage, handover and interference relationship based on DT drive test data: [0004] In the LTE (Long Term Evolution) system, based on the prediction and calculation of the wireless propagation model, the operator can usually obtain the neighbor cell topology relationship (NCR) design scheme of the wireless system by using the relevant planning software and the simulation of the planning tool. Since the pr...
