Patent ID: 8219091

Claim:
A method for use in a wireless transmit/receive unit (WTRU), the method comprising: generating an IEEE 802.16 subscriber station (SS) basic capability request (SBC-REQ) message including a first IEEE 802.21 media independent handover (MIH) support parameter comprising a first two or more bits indicating supported MIH capabilities of the WTRU; transmitting the SBC-REQ message to a base station; receiving a SS basic capability response (SBC-RSP) message from the base station in response to the SBC-REQ message, wherein the SBC-RSP message includes a second IEEE 802.21 MIH support parameter comprising a second two or more bits indicating supported MIH capabilities of the base station; and associating with the base station based on the received SBC-RSP message; wherein the second two or more bits indicate whether the base station supports an IEEE 802.21 MIH information service, whether the base station supports an IEEE 802.21 MIH command service, or whether the base station supports an IEEE 802.21 MIH event service.
