Abstract
A method for handover between heterogeneous radio access networks is disclosed. When a multi-mode mobile station performs Inter-RAT handover, pre-authentication is performed before implementing a link layer handover procedure with a target access point. The pre-authentication method has as little an effect on currently served quality of service as possible and the handover is efficiently performed using the pre-authentication method. The pre-authentication is performed through medium independent handover (MIH) and various MIH primitives for pre-authentication are provided.
