ABSTRACT In order to support the integration of heterogeneous networks and diverse access devices we have developed a server architecture that provides integrated telecommunications and data services spanning heterogeneous networks. The server architecture interfaces to the networks via adaptation units to provide a network independent service control on top of the networks. We have structured the architecture according to the principles of the TINA service architecture in a user control part, a service control part and a communication control part. We have adopted the IETF Session Initiation Protocol to serve as a service control layer signaling protocol. Our Session Control Protocol (SesCP) supports the setup and control of complex multimedia communication services and provides flexibility in order to support a wide range of new services. In particular SesCP provides signaling
