Abstract
To re-establish a direct tunnel between an access node and a gateway router in a wireless network, a control node that provides mobility management on behalf of mobile stations detects restart of the gateway router. In response to detecting restart of the gateway router, the control node sends context information regarding a previously established direct tunnel to the gateway router to enable the gateway router to re-establish the direct tunnel.
