Problems solved by technology

[0008] However, when performing PCI allocation in the prior art, random allocation is used. When the number of cells is too large, there will be confusion in the PCI allocation process, and the random allocation will cause confusion in high-priority cells, making the LTE system The overall performance of the

Embodiment Construction

[0054] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0055]figure 1 It is a flow chart of the PCI allocation method of an embodiment of the present invention; refer to figure 1 , the method includes the following steps:

[0056] 100: Acquiring the priority of each cell; calculating the priority of a cell is an existing technology, which has multiple calculation methods, and has been completed before implementing PCI allocation, so it will not be repeated here.

[0057] 200: Traversing the base stations, using the traversed base station as the current base station, and assigning a PCI group to each cell subordinate to the current base station according to the number and priority of adjacent cells to which PCI groups have bee...

Abstract

The invention discloses a method and a system for distributing PCIs (Physical Cell Identifiers), and relates to the technical field of mobile communication. The method comprises the steps of 100, acquiring the priority of each cell; 200, carrying out traversing on base stations, using a traverse base station to act as the current base station, distributing PCI groups to each cell subordinating to the current base station according to the number and the priority of adjacent cells, to which the PCI groups are distributed, of each cell subordinating to the current base station; and 300, carrying out traversing on the cells, using a traversed cell to act as the current cell, and distributing a PCI to the current cell according to the PCI group. According to the invention, the PCI groups are distributed to each cell subordinating to the current base station according to the number and the priority of the adjacent cells, to which the PCI groups are distributed, of each cell subordinating to the current base station, and then the PCI is distributed to the current cell according to the PCI group, thereby preventing cells with high priority from being confused, and enabling the overall performance of an LTE system to be greatly improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a PCI allocation method and system. Background technique [0002] Currently, the LTE system utilizes a Physical Cell Identifier (Physical Cell Identifier, PCI) for identification to distinguish sectors, base stations, and the like. In the LTE protocol, the value of PCI is 0 to 503, a total of 504, which are divided into 3 groups, and each group contains 168 different IDs. [0003] When performing PCI allocation, the following principles generally need to be followed: [0004] Non-conflict principle: ensure that the PCI values ​​of the same-frequency adjacent cells of a certain cell are not equal, and try to choose the PCI value with the best interference, that is, the PCI values ​​modulo 3 and modulo 6 are not equal. [0005] Adjacent cells are assigned the same PCI, resulting in at most one cell in the overlapping area being detected by the UE, and only one of the...
