Abstract:
A method and apparatus for multi-media communication includes transmitting a first session invite request (300) having a plurality of first call transaction identifiers (302). Each of the first call transaction identifiers (302) has a first call transaction value (303). Thereupon, the method and apparatus engages in a first communication session using the first session invite request (300). Concurrently, a second session invite request (400), having a plurality of second call transaction identifiers (402) having a second call transaction value (403), is also transmitted. A determination is made if the second session invite request (400) is duplicative by comparing the first and second call transaction values (303, 403) of the first and second call transaction identifiers (302, 402). A second communication session is engaged if the second session invite request (400) is not duplicative such that the first communication session and the second communication session create a multi-media session.
Abstract:
The present invention provides a method and apparatus that enables handover of a mobile station between a cellular network and a wireless network without control intervention from the cellular network and independent of employed air interface technology. In particular, the present invention is a wireless communication device (202) comprising a first transceiver circuit (604), a second transceiver circuit (606) and a main circuit (608, 610, 612, 614) coupled to the first and second transceiver circuits. The first transceiver circuit communicates with a first network within a first area of coverage, and the second transceiver circuit communicates with a second network within a second area of coverage. The main circuit is capable of operating the first and second transceiver circuits concurrently and handing-over communication for the call from the first transceiver circuit to the second transceiver circuit.
Abstract:
This invention provides a system and method for splitting control and media content signals of a cellular network connection of a mobile station. A mobile station (102) engages in a WAP browsing session with a cellular network connection (112) over an air interface. As a user moves into coverage area of an access point (126, 128, 130), another browsing session is established between the mobile station (102) and a non-cellular network connection (116, 118, 120). More specifically, the user's WAP browsing session with a cellular network connection (112) is upgraded to a Web browsing session with a non-cellular network connection (116, 118, 120). The present invention permits a user to control a Web browser on a remote device by providing user input to the mobile station (102).
