Problems solved by technology

However, in actual use, it is found that different frequency bands are used in the same cell, which is prone to problems such as inconsistency between the wireless coverage and service range of the cell, and the decline in call quality.

example

[0027] Example: Taking the frequency used by a certain operator's GSM system as 890-909 / 935-954MHz, 1710-1720 / 1805-1815 MHz, and 1725-1735 / 1820-1830 MHz as an example, if the original dual-frequency double-layer network base station configuration is as follows : GSM900 is 6 / 6 / 6, GSM1800 is 4 / 4 / 4, wherein, wireless traffic channel is divided into two parts of voice channel and data channel, and the ratio of data channel to traffic channel is 30%.

[0028] Note: In the following analysis, Irish Table B (blocking rate 1%) is used to analyze the change of wireless network voice capacity, and Irish Table C (congestion rate 5%) is used to analyze the change of wireless network data capacity.

[0029] According to the calculation and analysis, the capacity of the voice part provided by the single base station of the double-layer network is 94.56 ER, and the capacity of the data part is 34.14 ER.

[0030] According to the above theory, there are two cases to discuss:

Abstract

The invention provides a basic guiding principle of a new GSM (Global System for Mobile Communication) wireless network planning, points out the development direction of the traditional large 2G (second Generation) wireless networks, invents a unique dual-band frequency joint planning technology under the guidance of the principle, and once plans a dual-band and dual-structure GSM wireless network to a single-structure wireless network or a composite-structure wireless network which takes the single structure as main structure through joint planning in a zone where wireless base stations are densely distributed. A single-structure GSM wireless network planning chart is shown in abstract appended drawings. The technology can theoretically realize the purposes of rapid promoting the capacity of traditional dual-structure wireless networks by a large margin, saving investment and protecting the environment. The invention can reduce the number of neighboring subdistricts defined by each district and promote fusion of the 2G network with the 3G network.

Description

technical field [0001] GSM wireless network frequency planning technology. Background technique [0002] For a long time, one of the biggest bottlenecks in the development of GSM wireless networks is the shortage of frequency resources. At present, the GSM dual-frequency wireless network in many places has developed into a large-scale dual-frequency double-layer network, and their network base stations have basically formed a continuous and dense distribution, and wireless signals have formed seamless and continuous coverage, but the planning is still in the mid-term Compared with the early frequency planning method, the dual-frequency network is planned and built separately, that is, the GSM900 frequency and the GSM1800 frequency are planned separately to build a dual-frequency double-layer network. Due to the large number of users, the volume of voice and data services is large, while the radio frequency resources are tight and the network expansion is difficult, resultin...
