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. One or more monitoring entities monitor the availability of the access nodes and broadcast notification messages to other access nodes when an access node failure is detected. The broadcast message includes the identity of the failed access node. Other access nodes may take action to restore connections and recover session information maintained by the failed access node.
