Abstract: The present application describes various embodiments that address the need in wireless environments and within the SIP framework to efficiently maintain SIP contact addresses. It introduces the concept of a SIP proxy user agent (UA) (e.g., 123 or 124) to serve as a gateway between a SIP core network and a SIP-unaware mobile (101). A new parameter, called "created," is described for the contact header in SIP 200 OK messages, which is used to trigger deregistrations by SIP proxy UAs that no longer serve a particular mobile. It is this process for deregistering SIP proxy UAs that allows SIP contact addresses to be more efficiently maintained.

Abstract: The present application describes various embodiments that address the need in wireless environments and within the SIP framework to efficiently maintain SIP contact addresses. It introduces the concept of a SIP proxy user agent (UA) (e.g., 123 or 124) to serve as a gateway between a SIP core network and a SIP-unaware mobile (101). A new message is described, a combined registration and event subscription message, which is used by SIP proxy UAs to both register a new contact address for a mobile and to subscribe to the mobile's contact information. By updating and subscribing to the contact information, a SIP proxy UA is notified of subsequent changes to a mobile's contact information. Registration and deregistration of contact addresses can thus be effected in a manner that allows SIP contact addresses to be more efficiently maintained.

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.

Abstract: A method (600,700) and apparatus (800) are arranged and operate for facilitating call routing between sites in an enterprise connected by a private IP network (130). A range of identifiers (220-223) served by IP PBXs (120-123) in the enterprise may be registered with a SIP registrar (212) of an inter-site router (210). Call requests to a communication unit (350) outside the home site are routed to the SIP registrar. A site identifier associated with the destination IP PBX allows the call to be completed by the SIP Proxy or the IP PBX where the call was received. When no private IP network is available, a roaming CU registers with a cellular proxy in the visited network. Calls are routed by when an HLR (340) associated with the CU obtains the roaming number from the cellular proxy (330) in the visited site.

Abstract: A communication unit ( 10 ) with dual-mode operating capability comprises: a receiver ( 203, 204 ) and a transmitter ( 207, 208 ) for supporting an initial connection with another communication unit ( 12 ) on a first wireless network ( 16, 18, 20 ); and a controller ( 205 ), coupled to and controlling the receiver and transmitter, to maintain the initial connection and receive messages from or send messages to the other communications unit to effectuate a new connection over a second wireless network ( 11 ). A corresponding method includes while participating in an initial connection ( 302 ) detecting availability of a new connection ( 304 ) and establishing the new connection by exchanging messages between the communication units over the initial connection ( 310, 312 ).

Abstract: A dual-band wireless subscriber unit (SU) ( 112 ) having an enterprise address of E 1 and a cellular address of C 1 , 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 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.
