摘要：
A radio interface layer media independent handover (RIL MIH) client functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers and proxies, informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.
