| Title of Invention | A SUBSCRIBER UNIT (SU) THAT IS SIP ENABLED FOR FACILITATING A HANDOFF OF THE SU FROM A SIP-ENABLED WIRELESS LOCAL AREA NETWORK (WLAN) |
|---|---|
| Abstract | A dual-band wireless subscriber unit (SU) (112) having an enterprise address of E1 and a cellular address of C1, corresponding method (200), software program (310-320), and WLAN (104) determines (202) that the SU is about to leave a wireless local area network (WLAN) (104). In response, when the SU is involved in a call on E1, the SU sends (212, 208) to the WLAN a SIP message, for example a Refer message with a 'Refer To' field of C1 if an ongoing call or a SIP Redirect message with a contact address of C1 if a new call is attempting to begin on E1. In response to receiving either message, the WLAN seamlessly transfers (210, 214) the call to C1. |
