Abstract
The exemplary Multimedia Next Generation Network architecture disclosed herein covers the entire next generation system, e.g. for wireless communication services, including application, signaling and bearer functionalities. The architecture addresses unification of subscriber databases for both SIP services and non-SIP services in a Services Data Management Center (SDMC). A Security Center (SC) provides a central repository for all security related databases and functions. An Application Control Point (ACP) provides a single point of services control for all active SIP services for all subscribers via state information and services interaction management. Policy decisions are made at the packet layer, for example in an Advanced Bearer Control Point (ABCP) clustered with other functions to form a Bearer Services Control Point (BSCP). Policy enforcement is implemented at various nodes at the network or packet layer (L3) and above, e.g. including the BSCP and ACP.
