Various embodiments relate to a system and related method for managing a connection of a user device to a communications network. Various embodiments relate to a Policy and Charging Rules Node (PCRN) receiving a user requests through multiple serving gateways. The PCRN may assign one of the serving gateways as a primary serving gateway when the serving gateway sends a Gateway Control Session that binds to an IP-CAN session established in the PCRN. When the PCRN receives a subsequent message from another serving gateway, the PCRN may reassign the new serving gateway as primary when its Gateway Control Session matches. The PCRN may then mark the former serving gateway as pending termination and signal the marked gateway to terminate. After sending rules to serving gateways not pending termination, the PCRN may delete those serving gateways marked for termination.

Various embodiments relate to a system and related method for charging an actual subscriber using a single subscriber profile. A Policy and Charging Rules Node (PCRN) may receive a message including a service request and may refer to a subscriber profile to add at least one subscriber identifier (ID) to the message. An Online Charging System (OCS) may thereafter receive a translated message originating from the PCRN and use the at least one subscriber ID included in the translated message to find charging information for the actual subscriber. The OCS may include the charging information in a charged message. A device providing service may then use the charged information to charge the actual subscriber for the requested service.

A system for providing resilient multimedia broadcasting services over a VPLS network is described. A network Management System (NMS) calculates disjoint minimum cost trees using the Steiner algorithm executed with extra steps to result in the disjoint trees. Destination PE routers in the VPLS network are connected to the disjoint trees so that they can be serviced by either tree in the case of a fault. Each of the disjoint trees is provisioned with enough bandwidth to carry all of the services provided by the VPLS network. Under normal operation, however, the services are distributed evenly over the trees. In the event of a fault, the services on the faulty tree are switched to the other tree using split horizon bridging. Each Steiner tree can also be realized using poin-to-multipoint LSPs which is fully protected by a precomputed point-to-mulltipoint LSP.

Various exemplary embodiments relate to a method and related network node and machine-readable storage medium including one or more of the following: receiving, at the PCRN, the application request message; determining at least one requested service flow from the application request message; for each requested service flow of the at least one requested service flow, generating a new PCC rule based on the application request message; and providing each new PCC rule to a Policy and Charging Enforcement Node (PCEN). Various exemplary embodiments further include an application request message including at least one media component and at least one media subcomponent and the step of for each media subcomponent, determining a requested service flow from the media subcomponent.

Apparatus and method are provided for enabling establishment of cross-domain services, including exchange of reachability information between domains, routing of services across domains, and differential labeling. The network element control and management planes are supplemented by additional components that enable the control and management planes of each domain to inter-communicate in a peer-to-peer manner. Adjacencies are established between domains, and service reachability information is exchanged between domains. Network Service Applications within the management planes can then establish services across the domains by inter-communicating.

Managing subscriber host information is disclosed. A new or updated information about a subscriber host is received. It is determined whether the subscriber host is associated with a multi-chassis peering. If it is determined that the subscriber host is associated with a multi-chassis peering, the new or updated information is propagated to a peer chassis associated with the multi-chassis peering.

An apparatus and methods for real-time policy evaluation in support of network management and service provisioning are presented. The apparatus includes a policy repository, a scheduler, a triggering module, a pre-computation module. A policy equivalency class association is determined for each policy-managed entity, policy, policy-managed information flow of information and/or any part of a communication network. Policy conditions are divided into triggering and passive conditions. The scheduler prioritizes policy evaluation for policies associated with passive conditions for entire policy equivalency classes applicable to large numbers of policy-managed entities. Real-time events and updates are trapped via triggering conditions and related policy evaluation is performed for the entire policy equivalency class, for a large number of policy-managed entities, in real-time. A policy decision distribution mechanism provides policy-managed entities with policy decisions for enforcement. Policy evaluation includes changing the association of a policy-managed device with a group of policy equivalency classes. Advantages are derived from real-time policy evaluation of policies related to entire policy equivalency classes, each policy equivalency class being associated with large numbers of policy-managed entities.

Apparatus, methods, and related data structures for validating a routing configuration in a communication system are disclosed. Routing information in a communication system is passively collected, illustratively from routing protocol advertisement messages. A routing configuration of the communication system is validated based on the collected routing information. Validation may involve comparing information associated with electronic addresses in an address space of the communication system with the collected routing information, and also or instead comparing an intended routing configuration with an explicit routing configuration, for example. A data structure may include information indicating an electronic address and information indicating a result of validating a routing configuration associated with the electronic address.
