Abstract

A system and method that enables a more flexible architecture in communication networks with separated call control and bearer control. The invention enables full support of the advantages of a communication network with separated call control and bearer control when interfacing with a further network with monolithic signalling. The invention also increases the flexibility of an existing payload connection, especially in the case of a malfunction. The invention uses the existing signalling protocols to transfer further information. Basically, information elements and methods to interpret the transferred information are stored in the receivers and senders of the information. This enables the receivers and senders of information to transmit more information than originally planned when the protocols where designed. So it is possible to identify a combination of a payload transmission device and a control node instead of a single device only. It is further possible, to identify an assignment as a further assignment. This allows the change of a current assignment for a radio access controller.
