Problems solved by technology

[0006] After the existing PCI setting method clusters the cells, it only randomly selects PCIs under the premise of satisfying the two original principles, which may cause conflicts in the selection of PCIs in the middle of the cells, and is not conducive to rapid promotion
In addition, after the original method clusters the cells, there is no complete mathematical model to represent the cluster of cells, which is not conducive to the rapid completion of PCI planning

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the examples and drawings, but the implementation of the present invention is not limited thereto.

[0029] Such as figure 1 What is shown is a schematic flowchart of an embodiment of a method for setting a PCI of a cell in an LTE network according to the present invention, which includes the following steps:

[0030] S11. Obtain an area that needs to be set for PCI, and divide the area into multiple regular hexagonal cells of the same size;

[0031] The area where PCI settings are required to receive input is divided into multiple cells in the entire area, such as figure 2 As shown, in this embodiment, each cell is set as a regular hexagon, the size of each cell is the same, and the size of the cell can be set according to actual needs.

[0032] S12: Perform equidistant clustering of the area according to the preset PCI multiplexing distance;

[0033] Before making wireless network planning, des...

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 the PCI of a cell in an LTE network, and a system for setting the PCI of a cell in the LTE network. Background technique [0002] In the LTE wireless network, due to the large-area use of same-frequency networking, PCI (Physical Cell Identifier, physical layer cell ID) settings become more important. Reasonable and efficient PCI settings can effectively avoid inter-cell interference and help UE (User Equipment) complete positioning. 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 primary synchronization (Primary Synchronized Signal, P-SS) and secondary synchronization signal (Secondary Synchronized Signal, S-SS). Physical layer cell ID Among them, the physical layer cell ID group mark The value range of is 0~167, and the physical layer...
