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-pro gress from a first base station to a second base station with reduced interruption in voice communication is also disclosed.
