ABSTRACT:
A method and apparatus to support a hierarchical architecture which integrates wireless mobile terminals into networks such as the Internet. This architecture provides for efficient packet transfers over mobile wireless networks by efficiently allocating wireless resources. Label Switched packet forwarding facilitates traffic engineering and internetworking by attaching short fixed length labels to communications packets at an entry node to a wireless network to provide an efficient path to an exit node of the same wireless network. Forwarding mechanisms and limited broadcasting of reachability information are used in managing and routing the communications packets through the wireless mobile network. The present invention also supports multiple radio links between a mobile and a multiplicity of base stations. Multi-link techniques are used to affect an efficient packet transfer and admission policy.
