    Abstract: PURPOSE: A method for registering a mobile IP(Internet Protocol) in an asynchronous mobile system is provided to reserve radio resources after reflecting a mobile IP registration fail in a home agent. CONSTITUTION: A TE(Terminal Equipment)(10) transfers an AT(ATtention) command(100) to an MT(Mobile Terminal)(20) using a PPP protocol. Receiving the AT command, the MT(20) executes a bearer setup procedure(121). If the MT(20) transmits a PDP context activation request(101) to a packet exchange(30), the packet exchange(30) selects a suitable gateway/FA(Foreign Agent)(40) and transmits a PDP context creation request(103). At this moment, the gateway/FA(40) transmits a mobile IP protocol agent advertisement(106) to the TE(10) through a signaling channel, without responding to the request from the packet exchange(30). In the same manner, the TE(10) transmits a mobile IP registration request(107) to the gateway/FA(40) through the signaling channel. The gateway/FA(40) transmits this mobile IP registration request(108) to an HA(Home Agent)(50). The HA(50) appoints a fail or a success to a mobile IP registration response(109). Then the HA(50) transmits the mobile IP registration response(109) to the gateway/FA(40).
