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.

In response, when the SU is involved in a call on E 1 , the SU sends ( 212, 208 ) to the WLAN a SIP message, for example a Refer message with a "Refer To" field of C 1 if an ongoing call or a SIP Redirect message with a contact address of C 1 if a new call is attempting to begin on E 1 . In response to receiving either message, the WLAN seamlessly transfers ( 210, 214 ) the call to C 1.
