Abstract

The invention provides a cell PCI setting method in an LTE network. The method comprises the steps of acquiring an area with the need of PCI setting and dividing the area into a plurality of regular hexagonal cells with the same size, carrying out equidistant clustering on the area according to a preset PCI reuse distance, selecting one cluster in the area as a cell cluster and generating the graph of the cell cluster, receiving inputted available CPI and carrying out CPI setting on the graph of the cell cluster according to different criteria of mod3, and carrying out replication and translation on other clusters in the area of the set cell cluster to complete the PCI setting of the area. The invention also provides a cell PCI setting system in the LTE network, and the cell wireless network PCI setting can be quickly and efficiently completed in the LTE network.

Description

technical field [0001] The invention relates to the field of wireless communication networks, in particular to a method for setting a PCI of a cell in an LTE network, and a system for setting a PCI of a cell in an LTE network. Background technique [0002] In the LTE wireless network, due to the large-scale use of same-frequency networking, PCI (Physical Cell Identifier, physical layer cell ID) setting becomes more important. Reasonable and efficient PCI setting can effectively avoid inter-cell interference and help UE (User Equipment, user equipment) to complete positioning and the like. The UE can obtain the PCI of the cell where it is located through the downlink physical layer synchronization signal. The synchronization signal is divided into a primary synchronization signal (Primary Synchronized Signal, P-SS) and a secondary synchronization signal (Secondary Synchronized Signal, S-SS). Physical Layer Cell ID Among them, the physical layer cell ID group marks The v...
