Abstract
Methods, systems and network elements are described to improve the speed of handover in a mobile radio telecommunications system. In one embodiment a mobile terminal () transmits a list of addresses of network nodes () to a target base station () in preparation for setting up a new radio link to the target base station (). The list of addresses can be used by the target base station () to select a node () which is common to both the old and the new communication path and to address this node directly without requiring a cross-over switch network query. The new path () can then be set up quickly ready for the handover to target base station (). In a further embodiment the network distributes pre-authenticated signatures for a mobile terminal () to the nodes () of the network currently supporting a communication. This allows local verification of a mobile terminal () when it attempts to set up a new radio link with a target base station (). In yet a further embodiment the target base station () starts fast power control with the mobile terminal () before the new communications path () has been set up through the network.
