Problems solved by technology
When the management station calculates the PCI code, it can only allocate it from the limited unused PCI code table. It cannot guarantee that the newly given PCI code and the PCI codes of other cells in the base station are still in a sequence of numbers, which is inconvenient for the operation and maintenance of the existing network to manage.
[0008] For this reason, the management station calculates multiple parameters and gives a set of conflict-free confusing PCI codes. Each calculation needs to filter and calculate all PCI code data, and the calculation process is time-consuming and complicated.
[0009] In addition, the conflict-free confusing PCI code calculated by the management station cannot be unified with other cells in the same base station, and does not conform to the status quo of current network PCI planning and use.

Embodiment Construction
[0077] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented.
[0078] At present, the 3GPP agreement stipulates that there are 504 PCI codes of pseudo-random numbers, which are the identification of TD-LTE network cell identification and channel synchronization. It is determined that if the PCI code of the base station in the system is improperly configured, the synchronization of the cell will be affected first, and the interference of the cell will be generated secondly.
[0079] For this reason, in actual networking applications, in a limited number of PCI code configurations, different cells with the same PCI code will inevitably appe...

The invention discloses a PCI code configuration method and device of a base station. The method comprises steps that when PCI code groups are allocated, the geographic location of the base station tobe-allocated PCI codes is acquired; whether the geographic location of the base station belongs to one area of nine squared-figure areas is checked; if yes, at least three consecutive PCI codes are selected to allocate to the base station; the three consecutive PCI codes are unassigned PCI codes in the PCI code group corresponding to the area to which the geographical location of the base stationbelongs. The method is advantaged in that the PCI code allocation speed can be improved, possible conflict and confusion existing in the PCI codes can be reduced, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of communications, in particular to a PCI code configuration method and device for a base station. Background technique [0002] The 3GPP (3rd Generation Partnership Project, third-generation partnership project) specification has added SON (Self Organizing Network, self-organizing network) technology. In this specification, TD-LTE (Time Division Long Term Evolution, time-sharing long-term evolution) The system can replace the manual operation of the traditional network through self-organizing functions such as self-planning, self-installation, self-configuration, self-optimization, self-healing, and self-backhaul of the wireless access network, thus greatly reducing the participation of operation and maintenance personnel and reducing Operators' network construction and operation and maintenance costs. [0003] Self-configuration can greatly reduce the process of repeated manual configuration of parameters...
