A method and an apparatus for switching data between a set of input bitstreams and a set of output bitstreams in a circuit switched time division multiplexed network is presented. Each bitstream is divided into recurring frames and each frame is divided into time slots. Each one of the input bitstreams is received, and frames of time slot data thereof are temporarily stored in a set of memories. Each of the memories is used for storing frames of a respective bitstream of the input bitstreams. For each frame of each one of the output bitstreams, and sequentially in accordance with the order that the time slot data are to be transmitted in the respective output frame, time slot data is selectively read from frames presently temporarily stored in the set of memories, and is then transmitted into allocated time slots of the output bitstreams.

The present invention refers to transferring of data in a mobile communication network. According to the invention, data is transferred between one or more mobile switching centers and one or more of a plurality of base stations via one or more controllers, each controlling a respective group of the plurality of base stations, at least in part using a Dynamic Synchronous Transfer Mode type network.
