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.

Re-establishing a direct tunnel between an access node and a gateway router

A first group of core network (CN) nodes are arranged for transmitting a change request from a source to a target radio network controller (RNC), to a CN node selected from the set of CN nodes to which the target RNC is connected. Relating to a communication in progress with a first RNC () and a first CN node (), for which a change from the first to a second RNC () is requested: the change request is transmitted from the first CN node to a second CN node () of the first group, and is forwarded from the second to a third CN node () selected, according to predetermined criteria, from the set of CN nodes to which the second RNC is connected.
