Control of communication traffic

Abstract

Communication traffic for sets connected to the same access network is controlled where every call request is linked to a local exchange. A protocol in the access network and the local exchange makes it possible to connect sets connected to the access network to communicate with each other. An identifying device in the local exchange identifies call request signals having the destiny to the same access network from which a call request comes from in order to send back an allocation signal to set up the call inside the access network according to the protocol without having a pathway for the call in question between the access network and the local exchange during the call connection. Calls to sets not connected to the same access network are set up and served in the same way.
