Abstract
To initiate a communication session between a mobile station and an application server, the mobile station sends a reconnect message to a base station to reestablish a communication channel for a dormant packet data session. The reconnect message includes an encapsulated call control message to said application server. The base station extracts the call control message from the reconnect message and forwards the call control message towards the application server, while proceeding to reestablish a communication channel with the mobile station.
