In this paper, we analyze the network architecture, authentication, and key agreement of GSM and UMTS to compare the handover between the systems. And then, we divide authentication and key agreement procedure of mobile subscribers into several cases and finally analyze the key agreement procedure when a handover occurs in a CS-Domain and a PS-Domain.
