Abstract

The invention relates to a mobile communication system comprising transcoder units (TRCU) located remote from base stations (BTS1, BTS2) for decoding an encoded speech signal received from a mobile station (MS) and for encoding a speech signal to be transmitted to a mobile station. For switching the calls, there are network connections that are allocated call-specifically between a base station, a base station controller and a mobile services switching centre, a speech signal being transmitted over said network connections in transmission frames. In accordance with the invention, the base station controller switches a local speech or data connection under control of the mobile services switching centre, without a need to establish a speech/data connection between the base station controller and the mobile services switching centre when two mobile stations are located in the area of the same base station system. If there is a direct transmission link (21) between two base station controllers, they will switch network connections directly between the base stations located within their area. The invention also relates to call control methods.
