Embodiment Construction

[0031] Such as figure 1 Shown, a kind of community PCI configuration method comprises steps:

[0032] S100: Read basic network information, and acquire neighbor measurement data according to the basic network information.

[0033] The basic network information may include cell name, cell latitude and longitude, cell azimuth, ECGI (E-UTRAN Cell Global Identifier, E-UTRAN cell global identifier) ​​and neighbor cell information. In the communication network, there are multiple physical cells. In order to distinguish these cells, each physical cell is uniquely identified—PCI. The entire LTE network is a huge network. In order to accurately locate the cells that need to be searched (serving cell), which needs to be obtained from data analysis such as cell name, cell longitude and latitude, cell azimuth, and ECGI. In the entire LTE network, there may be associations between cells, and a cell associated with a serving cell is called a neighboring cell. The correlation degree betwe...

Abstract

The invention provides a cell PCI (peripheral component interconnect) allocation method and a cell PCI allocation system. The method includes: analyzing cell closeness according to neighboring measurement data and switchover data to acquire correlation coefficients of co-frequency cells, distributing cell PCI values for many times according to the correlation coefficients of the co-frequency cells, accurately calculating disturbance values, adjusting cell PCI distribution values for many times to form various different PCI planning schemes, respectively calculating a whole-network total disturbance value in each scheme, selecting an updated scheme with the lowest disturbance value to carry out convergence determination, and carrying out cell PCI allocation according to the updated cell PCI planning scheme during convergence determination, so that reasonable allocation of cell PCI values is realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for configuring PCI of a cell. Background technique [0002] PCI is the physical cell identifier of the LTE (Long Term Evolution, Long Term Evolution) network. It is used to distinguish the wireless signals of different cells. The value range is 0-503. Secondary synchronization signal), the value range of PSS is 0-2, and the value range of SSS is 0-167. [0003] PCI planning should follow the following constraints: 1. The PCI modulus 3 of different cells under the same base station is different, that is, mod(PCI1, 3)≠mod(PCI2, 3); 2. The residual value of PCI modulo 6 in adjacent cells is different, that is, mod(PCI1, 6)≠mod(PCI2, 6); 3. The PCIs between all adjacent cells are not equal, that is, PCI(1)≠PCI(2); 4. The residual value of PCI modulo 30 in adjacent cells is different, that is, mod(PCI1, 30)≠mod(PCI2, 30). [0004] It can be seen that in ...
