Service architecture for infrastructure based multi-hop networks based on SIP

A new service concept for a mobile broadband system called the wireless media system (WMS) is introduced. The WMS will provide broadband access to terminals with medium velocity of movement and is embedded into a cellular radio network to support a high velocity of terminals with medium transmission rate. An intelligent service control and advanced radio resource management for a power-optimized exploitation of multiple air interfaces will provide a virtually continuous radio connectivity to the WMS although the physical radio connectivity might be discontinuous. Broadcast, multicast and single-cast services will be combined to minimize the number of transmissions needed to provide the contents requested by the users. The concept of the intelligent service control as well as basic service concepts and multimedia applications and usage scenarios are presented.
