Method for wireless video communication using a high data rate packet data service and mobility management. In one embodiment mobile users (MS1 4, MS2 14, MS3 24) transact a video conference call sending the real-time data in packetized format. Mobility management allows location of each user according to an Internet Protocol (IP). In one embodiment, each mobile user communicates through a Session Initiation Protocol (SIP) type server (SIP1 108, SIP2 118, SIP3 128), which allows a mobile station to be located as it roams outside of its home network. The home SIP server provides a new SIP server location when a user moves outside of the home network (105, 115, 125). In an alternate embodiment, the users employ a Mobile-IP service, allowing each to have a persistent IP address, where mobility management functions inform a home agent (PDSN1 8, PDSN2 18, PDSN3 28) of the mobile user's location.
