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.

Proper allocation of network bandwidth is a crucial issue in rendering certain performance guarantees to meet the growing customer demands. Hence, allocation methodologies must explicitly be carried out for these guarantees to be given as efficiently as possible since the shared resources are limited. This invention presents methods and systems for Dynamic Bandwidth Management (DBM) and Quality of Service (QoS) in packet-based networks. DBM is an algorithm that dynamically adjusts the resource allocation in the IP Access Networks based upon measured QoS at the IP Core Network through an implementation of a Feedback Control Mechanism to manage available core transport bandwidth. Such a Feedback Control Mechanism is capable of maintaining a condition of non-congestion, a sufficient and necessary condition to meet end-to-end QoS requirements in a Next Generation Network (NGN). The emphasis is given on the system implementation of QoS policies for the fair distribution of network resources through a scalable architecture comprising key Resource and Admission Control Functional (RACF) entities, namely: a Network Management System (NMS), a QoS Manager, an Access Controller Manager (ACM), the Access Controllers, and the active probes.

A data-processing network based on a new Internet protocol features a modified addressing system, a novel routing method, resolution of congestion problems in the routers, differentiated transport of data, real-time videos and communications, a multicast system to distribute real-time videos, and data transport with quality of services. The network uses homogeneous network protocol to transport multi-cast, real-time stream, and file data over the same network and to provide multiple qualities of service. Multi-packets may be unpacked at any node for predictive and reactive congestion control and dynamic packet routing. Specifically, a network node updating adjacent nodes with its congestion status, so that each node dynamically routes data away from any congested nodes and prioritizes higher quality of service traffic. In routing data, paths not stored in data packets, but instead, paths are dynamically recomputed around congestion or failed nodes and multicast data is routed using bread crumb trail techniques.

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.
