Application of GSM system multiple control channels in cells

Abstract

The invention discloses an application of GSM system multiple control channels in cells, which makes fully use of a base station controller (BSC) and communications cells. The application is characterized by comprising the following steps of dividing main cells and auxiliary cells, enlarging the capacity of common control channels (CCCHs), and allocating the frequency. As for the application, each communication cell is divided into a main cell and a plurality of auxiliary cells according to hierarchy in sequence, thereby cell division is realized; a plurality broadcast control channels (BCCHs) are added into the main cells and the auxiliary cells, the main cells correspond to main BCCHs and the auxiliary cells correspond to auxiliary BCCHx, thereby effectively increasing the number of the BCCHs and the group number of the CCCHs and structurally making full use of a frequency multiplexing technology, i.e. the main cells realize 6*3 or 4*3 multiplexing, and the auxiliary cells can realize 1*3 aggressive multiplexing; the capacity of the system is enlarged; the problems of CCCH overload and shortage of cell resources are solved; the coverage range of the auxiliary cells is absolutely smaller than that of the main cells, thereby increasing the degree of the frequency multiplexing of carrier frequency and improving the anti-interference ability; no frequency hopping is needed, and the signal quality is stable.

Description

technical field [0001] The invention relates to a communication technology, especially the global system for mobile communication GSM. Background technique [0002] Global System for Mobile Communications GSM full name: Global System for Mobile Communications, is a mobile communication technology standard originated in Europe, is the second generation of mobile communication technology. The GSM frequency is stipulated by the agreement, and resources are allocated to different operators, and each operator only occupies a part of the entire frequency band. Therefore, for each operator, the frequency resources are very limited. How to make full use of these frequency resources and maximize the benefits is the goal that every operator strives for, which is directly related to the maximum capacity and service quality of the system. In the existing GSM system, a space cell is used as the smallest network element unit, and the communication frequency used is reused in another cell...

AI Technical Summary

Problems solved by technology

One BCCH corresponds to one CCCH. To increase the traffic can only increase the voice channel. Multiple voice channels share one CCCH. When multiple voice signals are input, the system is forced to discard a large number of paging, resulting in communication failure.

[0005](3) Due to the increase in capacity and insufficient site resources, it is difficult to obtain a reasonable address for a new site, and there is no mitigation technique

[0006](4) Due to insufficient frequency, there are few channel resources in the cell; there are many cells, many adjacent relationships, a large amount of data production, and the rate of system data services is affected by reselection.
