Abstract: A data communication system is provided that allows for the efficient management of data communication sessions requested from a plurality of packet data servicing nodes organized in a cluster, each member of the cluster managing a cluster session table which contains data identifying mobile units and packet data servicing nodes which are servicing data sessions with the mobile unit. As a mobile unit moves from one portion of the system to another, a network element will request a data session from a packet data servicing node, the packet data servicing node is then able to access the cluster session table to determine if the data session is already being served by another member of the cluster. If the data session is already in existence, the base station controller will be directed to request a data session from the packet data servicing node which is already servicing that session.

Abstract: A resource manager 20 receives and compiles data from a plurality of base transceiver station 14 to enable an admission control decision before beginning a communication session with a mobile unit 12. The historic usage patterns of the mobile unit 12 and the historic and present bandwidth availability for cells likely to be impacted are taken into account to make the admission control decision.

Abstract: A data communication system 10 is provided that allow for the efficient management of data communication sessions requested from a plurality of packet data servicing nodes (22-28) which are organized in a cluster 32, each member of the cluster 32 manages a cluster session table which contains data identifying mobile units 12 and packet data servicing nodes (22-28) which are servicing data sessions with the mobile unit 12. As a mobile unit 12 moves from one portion of the system 10 to another, a network element such as a base station controller 40 will request a data session from a packet data servicing node 28, the packet data servicing node 28 is then able to access the cluster session table to determine if the data session is already being served by another member of the cluster 32. If the data session is already in existence, the base station controller 40 will be directed to request a data session from the packet data servicing node 32 which is already servicing that session.

Abstract: A router in a network comprises an interface system for receiving packets and has a plurality of channels and a plurality of framing service engines. The router is configured to assign the channels to individual framing service engines for framing services. The router has a channel manager for performing the assignments, and the channel manager is configured to receive and use data about the framing service engines. The router further comprises a framing memory for buffering communication between the interface system and the plurality of framing service engines. At least one framing service engine is configured to frame packets and at least one framing service engine is configured to deframe packets, and the framing service engines may be configured to operate on AHDLC packets. The router can be used with an interface system that comprises a plurality of network interfaces terminating a plurality of point to point links.
