摘要：
A Media Independent Handover (MIH) server communicates with nodes in a cellular network to perform handover of a wireless transmit/receive unit (WTRU) in the event of an incoming circuit-switched (CS) call. A Gateway Mobile Switching Center (GMSC) and/or Home Location Register (HLR) receive an indication of an incoming call, and may communicate with the MIH server. A determination is made regarding whether the WTRU is active in the cellular network. When required, the MIH server initiates an MIH handover of the WTRU to the cellular network. The WTRU hands over to the cellular network and receives the call. Additionally, an MIH server and a HLR communicate location information associated with a WTRU. The location information may be used by the MIH server and HLR to perform their respective MIH and HLR functionality, and/or to handover the WTRU to a cellular network in the event of an incoming CS call.
