Problems solved by technology

In the design of the base station controller BSC, some manufacturers use E1 line connection between the site and the base station controller BSC, adopt site cascade connection or do not use any convergence measures, because the existing base station controller BSC has large capacity and many sites, and In the actual environment, the capacity of the base transceiver station BTS is often relatively small. Sometimes each site has only a few transceivers TRX. The LAPD channel of the road access protocol cannot be converged, and there are certain additional requirements for the base transceiver station BTS, the convergence effect is not ideal, resulting in a large waste of transmission lines and increasing transmission costs

Embodiment Construction

[0016] Such as figure 1 As shown, taking 5 sites and 6 transceivers TRX in each site to connect with the base station controller BSC as an example, 5 E1 lines are required, and the E1 transmission line from the base transceiver station BTS to the wireless management module RMM section contains services Channel TCH, D channel link access protocol LAPD channel. The capacity of the base transceiver station BTS is often relatively small, and there are still some idle channels. The allocation of E1 channels is related to the capacity of the base transceiver station BTS. The larger the capacity, the more LAPD channels and TCH channels of the D channel link access protocol. In this way, a large number of useless channels occupy the E1 line virtually, resulting in an increase in long-distance transmission costs.

[0017] Due to the large load of the large-capacity base station controller BSC, in order to fully utilize the requirements of network resources, the base station controlle...

Abstract

A transmission convergence method of base station controller is disclosed. The radio resource management module RMM is positioned far from the system control module SCM and close to the sites. A time slot exchange technique is used to filter out the useless idle channels and switch the useful service channels to the convergence interface ABIS. Then they are transmitted to the SCM. Its advantages are low transmission cost and flexible extension of system.

Description

technical field [0001] The present invention relates to communication technology, in particular to a transmission convergence method suitable for base station controllers used in Global System for Mobile Communications (GSM), especially a method that can reduce long-distance transmission connections and minimize the transmission volume of base station controllers A transmission convergence method for base station controllers. Background technique [0002] At present, as the number of users of the Global System for Mobile Communications (GSM) increases, the capacity of the GSM network becomes larger and larger. Therefore, as an indicator, operators often regard the capacity of the base station controller as one of the requirements for model selection. Now the global mobile communication system networking requirements are generally a mobile switching center MSC with one or two base station controllers BSC, so that the base station controller BSC is required to provide a large...
