Abstract:
1. A system for providing a first service which utilizes a first application layer (above Layer 3) service control protocol and a second service which utilizes a second application layer (above Layer 3) service control protocol, for subscribers' access terminals (ATs), the system comprising: an application layer comprising: at least one link layer (Layer 2) network element, each link layer (Layer 2) network element for: (1) providing two-way transport for packet communication for one or more of the subscribers' ATs for communications with the first application server for the first service in accord with the first application layer service control protocol, and (2) providing two-way transport for packet communication for one or more of the subscribers' ATs for communications with the second application server for the second service in accord with the second application layer service control protocol, wherein: a network layer (Layer 3) comprising an Advanced Bearer Control Point (ABCP) for tracking network layer (Layer 3) delivery of communication for the subscribers' ATs involved in communications through the at least one link layer network element, for tracking availability of resources for providing communication through the network, and for determining allocations of the resources to the subscribers' ATs for the communications for the first and second services through the network in accordance with a network policy; and a plurality of policy enforcement functions distributed across the network for controlling the subscribers' packet communications, so as to implement the determined resource allocations for the communications for the first and second services for the subscribers' ATs, wherein: the policy enforcement functions include the one or more Call Session Control Functions (CSCFs) in the application layer above network layer three (Layer 3), and the BTS of the at least one link layer network element is configured to implement a policy enforcement function by controlling routing of subscribers' communication packets so as to implement resource allocations determined by the ABCP, for the communications with the one or more of the ATs through the BTS.
