CHANNEL ALLOCATION IN A MOBILE COMMUNICATIONS SYSTEM

摘要

The use of frequencies can be made more efficient in a mobile communications system with frequency hopping and a method of discontinuous transmission. However, continuous transmission calls unsuitable for discontinuous transmission will hereby cause excessive interference in the network. This invention concerns a channel allocation method in a mobile communications system where some radio connections are implemented with a discontinuous transmission function. The method identifies continuous transmission calls for which according to the invention a fixed-frequency traffic channel defined as a continuous transmission traffic channel is allocated. In addition, the invention concerns an arrangement for allocation of a traffic channel in a mobile communications system where some radio connections are implemented with a discontinuous transmission function. The arrangement is adapted to identify continuous transmission calls. According to the invention, the arrangement is characterised in that it is adapted for allocation of a fixed-frequency traffic channel defined as a continuous transmission traffic channel for a continuous transmission call.
