Whole network pn modification method and device

Abstract

The invention relates to a method for modifying whole network PN. The method for modifying the whole network PN comprises the following steps that physical parameters of sectors are gathered, and planning of PN is conducted on scenes corresponding to the sectors in all sectors according to the gathered physical parameters; adjacent region lists of all sectors are acquired from base station subsystem devices, and the planned PN is replaced to the adjacent region lists; unreasonable PN and unreasonable adjacent region relations are screened from the adjacent region lists of all sectors, and a screened result is replanned; the PN in which the unreasonable PN and the adjacent region relations are eliminated is replaced to the adjacent region lists through replanning and screening, and a planned parameter list is formed into a configuration database file; the configuration database file is led into a configuration database under the off-line condition of the base station subsystem devices, and therefore formative configuration data are loaded and activated under the on-line condition. The invention further relates to a device for modifying the whole network PN. The method and device for modifying the whole network PN can achieve reasonable and efficient modification of whole network PN of a large-scale wireless communication network.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for modifying a pilot number (PilotNumber, PN for short) of the whole network. Background technique [0002] In a wireless communication system (such as a CDMA system), all base stations can use the same frequency to transmit signals, and use different PN codes to distinguish different sectors in the forward direction. [0003] The number of PN codes is strictly limited. In an actual network, the number of sectors is far greater than the number of PN codes. Therefore, multiple sectors may reuse the same PN in the network. In a certain area, if the terminal receives signals from the same PN at the same time, it will cause the terminal to make a wrong judgment on the sector, resulting in handover failure and call drop. This requires network configuration and optimization personnel to make reasonable plans for the same PN and neighboring P...

AI Technical Summary

Problems solved by technology

[0005] 1) The re-planned PN is only a more reasonable planning scheme by considering geographical location and other factors, but often the on-site wireless environment is very complex, and there are some handovers and neighbor relationships between sectors that are not normal factors

After importing a new PN, many abnormal neighbor relationships will be generated, which will affect network performance

[0006] 2) Adopt the method of dynamic modification. In addition to modifying the database, it is also necessary to dynamically load the data to the foreground for each modification. The command execution time is long, and it is often difficult to complete the modification of the entire network in a relatively short period of time.

[0007] Due to the above two technical defects, it is difficult to complete the modification of the PN of the entire network on a large scale by adopting conventional methods
