Description

Technical Field

[0001] The present invention relates to the field of 5G application technologies, and in particular to a 5G NR cell PCI automatic planning method and system. Background Art

[0002] In 5G NR, cells are generally distinguished by physical cell identifiers (PCIs). There are 1008 physical cell identifiers. Because of their limited number, especially with the large-scale deployment of 5G base stations and 5G home base stations and the operators' planning of PCIs in each area, the available PCIs will be greatly reduced. Therefore, PCI conflicts and confusions are likely to occur during the allocation process, which will increase the difficulty of PCI allocation.

[0003] The PCI conflict scenario is generally when the same PCI is configured between adjacent cells, while PCI confusion is because two adjacent cells of a cell are configured with the same PCI, resulting in the user equipment being unable to distinguish which cell is the target switching cell.

[0004] The commonly used solutions currently include the following steps:

[0005] 1) Initial PCI allocation includes random allocation and on-demand allocation;

[0006] 2) Conflict detection;

[0007] 3) Conflict resolution;

[0008] 4) Automatic adjustment;

[0009] 5) Subsequent inspection and maintenance.

[0010] The entire process described above is to deploy first, then automatically detect and resolve anomalies. However, if anomalies are detected after deployment, redeployment will undoubtedly increase usage costs, prolong user waiting time, and reduce user satisfaction.

[0011] In order to solve the above problems, the present invention proposes a 5G NR cell PCI automatic planning method and system. Summary of the invention

[0029] If the unused PCI range list of the corresponding frequency point of the cell to be deployed is not empty, the list is recorded and the output result is returned;

[0038] Step S3.4: Delete the PCIs in the neighboring area of ​​the cell to be deployed from the sorting table, and select the PIC farthest from the planned cell as the result for output.
