A signalling protocol provides the means to establish, maintain and terminate connections across a network between communicating application entities.
Multiconnection call contains multiple connections in a call, and in NNI each connection must be established individually. So the functions of distribution and synchronization of messages for multiconnection call setup is needed in call control application process. This paper described DSF structure which performs these functions and designed call setup message flow and state transition of DSF for multiconnection.
