Problems solved by technology

[0004] During the research and practice of the existing technology, the inventor found at least the following problems in the existing technical solution: only compatible with some equipment manufacturers' data, complex data format requirements, multiple data cannot be jointly analyzed and verified, and planned at the same time The method and process are relatively complicated, not easy to operate, and are insufficient for high-intensity network and regional planning and response speed. The above reasons limit the application range of existing technical products, and the effect of planning is also affected

Embodiment Construction

[0027] In the following, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand the technical idea claimed in the present invention more clearly.

[0028] Such as Figure 1 to Figure 3 Shown, a kind of frequency planning method of GSM network comprises the following steps:

[0029] A. Basic data collection and sorting: extract LAC, CI, BCCH frequency points, TCH frequency points, carrier frequency numbers, frequency hopping modes, neighbor cell relations, planning area, and hardware constraint information of live network cells, and combine them with engineering Parameter information, complete the basic information table, and then enter step B, step G and step H respectively; the engineering parameter information includes latitude and longitude, direction angle, downtilt angle, antenna type, and repeater information of the live network community.

[0030] It should be noted that step A is to p...

Abstract

The invention relates to a frequency planning method in GSM network. The frequency planning method in GSM network comprises the following steps: A, infrastructure data collection and collation; B, coverage optimization; C, neighboring optimization; D, optimization of same frequency and same BSIC (Base Station Identity Code); E, measured data collection and collation; F, interference matrix building; G, frequency model judgment; H, planning object selection; I, frequency planning; and J, cutting implementation according to frequency planning results; Step B is based on data of Step A, in Step B, a comprehensive general survey on the planning network is made, an antenna of the network, a repeater, an indoor distribution system and an extension system are understood and mastered comprehensively; and then coverage is optimized; Step G is based on data of Step A, through the analysis of network mean carrier frequency configure number and density of mean carrier frequency configure per unit area, the method for optimal frequency multiplexing model is acquired; Step G is based on data of Step A, according to requirements of the planned residential areas, a region, scale and capacity, the method for planning the region is acquired. The invention has high response speed.

Description

technical field [0001] The invention relates to the communication field, in particular to a frequency planning method for a GSM network. Background technique [0002] GSM (Global System for Mobile Communications) adopts multiple access methods of TDMA and FDMA, wherein the FDMA system divides channels based on frequency. Each user communicates in a pair of channels. If other signal components fall into the frequency band of a user receiver, it will cause interference to the useful signal. If the frequency planning is not good during the overall network planning, some performance indicators will not meet the requirements after the entire network is completed or expanded. Interference from adjacent cells on the same carrier frequency results in better reception level but poor reception quality, and even call drop. At present, with the reduction of mobile communication tariffs, the traffic volume has increased sharply, the scale of the GSM network has continued to expand, th...
