A method of changing the IP address allocated to a mobile UE during a SRNS relocation process in a mobile telecommunications system and in which relocation process, control of the UE is transferred from a currently Serving Radio Network Subsystem (SRNS) to a Target RNS. The method comprises, prior to said SRNS relocation taking place, notifying the UE of a new IP address or means for generating a new IP address. During the SRNS relocation process, or immediately thereafter, the previously used IP address is replaced with the new IP address as the in-use IP address. |
