Abstract: A method for managing a mobility of a 3G access system using an SIP(Session Initiation Protocol) is provided to decrease a signal delay by modifying a standard SIP protocol at an application layer. A mobile terminal transmits an SIP register message to an SMA(301). The SIP register message having a new IP(Internet Protocol) address for the mobile terminal is forwarded to a home SIP register(302). The home SIP register delivers a non-authorized message to an SMA(303). The SMA(Session and Mobility Agent) forwards the non-authorized message from the home SIP register to the mobile terminal(304). The mobile terminal delivers the register message with validity information to the SMA(305). The SMA forwards the register message containing valid information to the home SIP register(306). The home SIP register delivers a success response with respect to the register message to the SMA(307). The SMA forwards the success response to the mobile terminal(308). The SMA delivers an ACK to the mobile terminal(309). An automatic address configuration is performed in the mobile terminal(310). The ACK response is delivered to the SMA(311). The SMA forwards the ACK response to the home SIP register(312).
