Multimedia next generation network architecture for IP services delivery based on network and user policy
First Claim
1. A packet switching network for providing communication for a first service which utilizes a first application layer (above L3) service control protocol and communication for a second service which utilizes a second application layer (above L3) service control protocol, for subscribers'"'"' access terminals (ATs), the network comprising:
- a link layer (L2) network element for providing two-way transport for packet communication with one or more of the subscribers'"'"' ATs;
an Advanced Bearer Control Point (ABCP) for tracking network layer (L3) delivery of communication for the one or more of subscribers'"'"' ATs involved in communications through the link layer network element, for tracking availability of resources for providing communication through the network, and for determining allocations of the resources to the one or more ATs for the communications for the first and second services through the network in accordance with a network policy;
a plurality of policy enforcement functions distributed across the network for controlling the subscribers'"'"' packet communications at network layer three (L3) or above, so as to implement the determined resource allocations for the communications for the first and second services for the one or more of the ATs.

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.

20. A system for providing layer three (L3) control of subscribers'"'"' packet communications through a packet switching network for users'"'"' access terminals (ATs), for a first service which utilizes a first application layer (above L3) service control protocol and for a second service which utilizes a second application layer (above L3) service control protocol, the system comprising:
-
(a) an Advanced Bearer Control Point (ABCP) for tracking network layer (L3) delivery of communication for the ATs through the network, for tracking availability of resources for providing communication through the network, and for determining allocations of the resources to the ATs for the communications for the first and second services through the network in accordance with a network policy; (b) a router for routing packets between the ATs and a core packet network for the first and second services; and (b) a policy enforcement function for controlling the routing, so as to implement at least some of the determined resource allocations for communications through the network for the one or more ATs for the first and second services. - View Dependent Claims (21, 22, 23, 24, 25)

26. An Application Control Point (ACP) for providing application layer (above L3) control of subscribers'"'"' packet communications for a plurality of services through a network that utilize a common application layer (above L3) service control protocol, the ACP comprising:
-
(i) a Services Capability Interaction Manager (SCIM), for providing the control of subscribers'"'"' packet communications for the plurality of services through the network; and (ii) a database accessible by the SCIM for transient storage of service profile data for the subscribers, for use by the SCIM in its control of packet communications for the plurality services provided through the network for the subscribers'"'"' access terminals (ATs), wherein; the SCIM uses subscriber profile data from the database to provide the application layer control of subscribers'"'"' packet communications for the plurality of services through the network, and the ACP is configured for providing a single point of services control for all active services utilizing the common application layer (above L3) service control protocol for all subscribers'"'"' ATs, responsive to a network policy decision from a policy decision function implemented at the network layer (L3) of the network.
