A method and system for conveying media independent handover (MIH) capability information are disclosed. A wireless communication system includes a plurality of wireless networks deployed under different wireless communication protocols. A multi-mode wireless transmit/receive unit (WTRU) may perform a handover from one wireless network to another for continuous reception of services. The wireless network sends a message to the WTRU which indicates whether the wireless network supports MIH services and a supported MIH mode. The WTRU receives the message and makes a handover decision based on the message.
