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 (114) transmits a list of addresses of network nodes (102, 103, 105, 122, 125) to a target base station (106) in preparation for setting up a new radio link to the target base station (106). The list of addresses can be used by the target base station (106) to select a node (122, 125) 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 (122, 110, 106) can then be set up quickly ready for the handover to target base station (106). In a further embodiment the network distributes pre-authenticated signatures for a mobile terminal (114) to the nodes (102, 103, 105, 122, 125) of the network currently supporting a communication. This allows local verification of a mobile terminal (114) when it attempts to set up a new radio link with a target base station (106). In yet a further embodiment the target base station (106) starts fast power control with the mobile terminal (114) before the new communications path (125, 110, 106) has been set up through the network.

By so doing, it allows IP handover processing to be initiated at higher speed than in the case of the conventional IP layer, thus enabling to reduce the total time of handover processing.

A method of triggering handoff of a mobile station to a candidate BSS, for VoWLAN communication, uses a roaming controller for monitoring link qualities of the serving and candidate BSS by selective / controlled fast scanning through RSSI screening at each packet reception. Using link qualities, a list of candidate BSSs for handoff is maintained. The controller selects a candidate BSS for handoff and completes pre-authentication of the mobile station with the selected best candidate BSS. When the link quality of the of the selected candidate BSS becomes better than that of the serving BSS, handoff is triggered. Link qualities may be monitored by screening a metric other than RSSI. When no candidate BSS is found, scanning is reduced / temporarily interrupted, to conserve power. When the serving BSS link quality is above a given threshold when the mobile station is in the serving BSS center, the functions of fast scanning and pre-authentication are interrupted.
