Abstract
A wireless network has a plurality of base stations, each configured to communicate with at least one portable device using a WLAN protocol. The wireless network also has a VoIP core network coupled to each of the base stations. A WLAN mobile phone has a VoIP processor coupled to an RF section and configured to monitor a current signal strength from a current base station and an alternate signal strength from an alternate base station, wherein the VoIP processor is configured to disassociate from the current base station when an analysis of the current signal strength and the alternate signal strength indicate that it would be better to associate with the alternate base station. A method of handing-off a VoIP call-in-progress from a first base station to a second base station with reduced interruption in voice communication is also disclosed.

38. A wireless local area network (WLAN) mobile phone, comprising:
-
an antenna;
an RF section coupled to the antenna; and
a VoIP processor coupled to the RF section and configured to monitor a current signal strength from a current base station and an alternate signal strength from an alternate base station, wherein the VoIP processor is configured to disassociate from the current base station when an analysis of the current signal strength and the alternate signal strength indicate that it would be better to associate with the alternate base station. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

54. A method of handing-off a VoIP call-in-progress from a first base station to a second base station with reduced interruption in the voice communication, comprising:
-
determining that a call association should be changed from the first base station to the second base station;
storing identifying information about the second base station before disassociating from the first base station;
disassociating from the first base station;
maintaining an IP address assignment which was active when the call-in-progress was associated with the first base station;
associating with the second base station; and
communicating with the second base station using the maintained IP address assignment. - View Dependent Claims (55, 56, 57, 58, 59, 60)
