Claim:
A method for re-connecting a mobile terminal roaming in a wireless network via a target base station after the occurrence of an uncontrolled disconnection of communications between said mobile terminal and a serving base station via which said mobile terminal was receiving and transmitting communications prior to said uncontrolled disconnection, and wherein said method comprises the steps of: establishing an entity associated with said wireless network operative as a single authentication access entity for said mobile terminal, as long as the location of said mobile terminal remains within said wireless network; providing the serving base station with an indication of the identity of said single authentication access entity; following the occurrence of uncontrolled disconnection and in response to an attempt made by said mobile terminal to reconnect to said wireless network via said target base station, receiving at the target base station an indication of the identity of said single authentication access entity, transmitted by said serving base station; and at the target base station, retrieving parameters associated with said mobile terminal from the single authentication access entity, wherein said uncontrolled disconnection is a member of the group consisting of: loss of connectivity between said serving base station and said mobile terminal, where the latter has not transmitted a handover request or a handover indication message; loss of connectivity between said serving base station and said mobile terminal, after receiving at said serving base station a partial indication of a handover process that said mobile terminal is about to undergo; receiving an indication, in a handover request transmitted by said mobile terminal, of a group comprising a plurality of base stations, and wherein said target base station has not been included in said group; and any combination thereof.
