Problems solved by technology

[0004] In the prior art, buffers are used to solve the problem of co-channel interference caused by signals in the GSM network to the WCDMA network. However, in the refarming-WCDMA network, when frequency resources are tight, there is a need for neighbors between the WCDMA network and the GSM network. Frequency deployment, resulting in adjacent frequency interference between the signal in the WCDMA network and the signal in the GSM network, thus affecting the signal quality of the refarming-WCDMA network

Abstract

The invention discloses a planning method and a planning device for frequency points, relates to the technical field of communication networks, and is used for solving the problem about adjacent channel interference of signals in a WCDMA network and a GSM network in a refarming-WCDMA network. The planning method comprises: determining an interference frequency point set and a core interference base station set, then obtaining a target base station set from the core interference base station set for deploying frequency points in the interference frequency point set, replacing the interference frequency points respectively corresponding to each target base station in the target base station set with the frequency points, which have not interfered WCDMA signals in a refarming-WCDMA network deployment area, in the refarming-WCDMA network deployment area and buffering area. The planning method and device for the frequency points provided by the embodiment of the invention are applicable to planning the frequency points.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a frequency point planning method and device. Background technique [0002] With the rapid development of high-speed data services, the pressure of data services in a Wideband Code Division Multiple Access (WCDMA) network is increasing. In order to alleviate the pressure of bearing data services, some frequency point resources in the Global System for Mobile Communications (Global System for Mobile communication, GSM) network can be refarmed, and then provided to the WCDMA network for use. Among them, refarming is a spectrum refarming technology. However, when the WCDMA system is deployed adjacent to the GSM system that uses the same frequency resources, the signals in the GSM network will cause serious co-channel interference to the WCDMA network. Therefore, it is necessary to add space isolation between the WCDMA system and the GSM system. buffer. [0...
