摘要： A method for inter RAT handover is disclosed. The method for inter RAT handover comprises measuring cell quality of WiMAX neighbor cells from a user equipment of E-UTRAN and transmitting the measured result to an origin base station; and if RRC message is received from the origin base station, the RRC message including WiMAX signal, pre-registering with a target WiMAX base station using tunneling based on second layer protocol. Therefore, the user equipment can continue to receive a service with maintaining current service quality even though the user equipment moves to a heterogeneous network. In addition, it is possible to reduce the time required for the user equipment to perform handover to the target base station. Moreover, if there is a failure of a radio link when the user equipment performs handover, it is possible to enable fast recovery.

摘要： This document is related to a method for acquiring information for media independent handover. More specifically the method comprises: submitting a media independent handover (MIH) query to a base station (BS) by sending a first request message, and receiving a response to the MIH query. Because the first request message is used for authorization, preferably the PKM message, the MS can acquire information for handover between heterogeneous networks before the MS finishes the network entry.
