A Provider Network Controller (PNC) addresses the challenges in building services across Next Generation Network (NGN) architectures and creates an abstraction layer as a bridge, or glue, between the network transport and applications running over it. The PNC is a multi-layer, multi-vendor dynamic control plane that implements service activation and Layer 0-2 management tools for multiple transport technologies including Carrier Ethernet, Provider Backbone Transport (PBT), Multi-protocol Label Switching (MPLS), Transport MPLS (T-MPLS), optical and integrated networking platforms. Decoupling transport controls and services from the network equipment simplifies service creation and provides options for carriers to choose best-in-class equipment that leverages the PNC to enable rapid creation and management of transports and services. The PNC provides Service-Oriented Architecture (SOA) interfaces to abstract transport objects expressly designed to support both wholesale and retail services, and supports service offerings with varied bandwidth and Quality of Service (QoS) requirements, thus achieving enterprise Ethernet economics.

A method to systematically analyze a next generation telecommunications network to result in creating a provisioning plan for provisioning the network to provide services for one or more subscribers. In one specific embodiment, the method involves creating and storing information that represents a logical decomposition of the next generation network into a plurality of discrete functional areas. The information representing the functional areas is analyzed to identify one or more provisioning requirements for each of the functional areas. One or more provisioning procedures are determined, and one or more required provisioning tools are identified for each of the functional areas, based on the provisioning requirements. A sequence of execution of the procedures and tools is created and stored as a provisioning plan.

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.

A method and system for re-direction and handoff for pre-paid mobile services in third generation (“3G”) networks. A handoff marker is created and used for wireless mobile nodes such as Mobile Internet Protocol (“Mobile IP”) nodes. The handoff markers allow the wireless mobile nodes to use pre-paid mobile services, have active communications sessions suspended and re-directed to a registration server when purchased pre-paid mobile services run-out. The registration server allows the wireless mobile node to electronically purchase additional pre-paid mobile services and immediately resume a suspended communications session. The handoff markers also allows network devices in a mobile network to determine between initiation of a new communications session or a hard handoff of an existing communication session, without adversely affecting pre-paid billing services.

A Next Generation Network (NGN) resource management system and method includes a network topology discovery mechanism at the scale of an administrative domain. Information about nodes and links, such as bandwidth, delay, jitter, name and description of devices is collected and stored in a database by way of a protocol.

Methods and systems for extending the IMS/SIP architecture of the NGN to provide QoS service to generic bearer flows. More particularly, a method is provided for establishing an bearer end-to-end path of a communication session in a multi-domain communication network in which an out of band signalling protocol is used to establish communications sessions. The method comprises receiving an out-of-band signalling message including information representative of at least an opposite end point of a first bearer segment of the end-to-end path. The information is used to define a cross-connect mapping through a node of the network between respective local endpoints of the first bearer segment and a second bearer segment hosted by the node. Information representative of the cross-connect mapping is then inserted into the out-of-band signalling message, and the out-of-band signalling message forwarded.

The present invention provides a method and an apparatus for performing resource management of one or more Internet Protocol based resources to route a plurality of packets. To ensure a relatively high end-to-end service quality, the method and apparatus defines one or more user-service specific metrics being utilized by Internet Protocol (IP) mechanisms on a network layer to provide an IP-based resource management in a next generation network. A wireless router may provide wireless radio access using a resource management that captures one or more properties of at least one network link and at least one wireless link as metrics that may be used by IP mechanisms. Based on metric related distributed information, each router including a wireless router and an IP router may determine whether or not to forward a packet on an associated wireless link or a network link. By not differentiating between a wireless link and a network link, the wireless and IP routers may enable routing of the plurality of packets through a converged network.
