Abstract
A mobile communication network includes a plurality of access nodes that can serve different roles in support of a communication session with a mobile station. An access node can serve as a connecting node that receives access requests the mobile station, as an anchor node to anchor a radio packet connection with a core network for the communication session; or as a primary node to store session information for the communication session. When the communication session is established, the anchor node for the communication session may select another access node to serve as the primary node. Session information can be stored at both the anchor node and primary node so that data can be delivered to the mobile station if either one of the anchor node and primary node are available.
