ABSTRACT:
Communication network and a corresponding method are disclosed for operating the communication network that has a packet switched protocol based cellular telephone network comprising a first layer for transferring signalling information assigned to a telephone call being processed by the communication network, a second layer for transferring payload information assigned to the telephone call and an interface for coupling the cellular telephone network to a further network, the interface comprising a signalling information exchange function between the cellular telephone network and the further network and a payload information exchange function between the cellular telephone network and the further network, the first layer and the second layer of the cellular telephone network being coupled to the interface, wherein the second layer of the cellular telephone network transfers the payload information of the telephone call to and from the interface on a direct route assigned to the telephone call within the second layer.
