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.
