ABSTRACT:
A method (and corresponding equipment) for use in case of a UE device (18) enabled for communication with other telecommunication devices via a network including a radio access network (17 21) and providing GPRS, the method for use in responding to a message from the network indicating a change in a SAPI connection from an old SAPI to a new SAPI, the method characterized by using a timer to provide that for a period of time set on the timer, the UE device (18) keeps the old SAPI active and handles messages received on both the old SAPI and the new SAPI.
