    摘要: The present disclosure relates to a communication method between a terminal and a network during an inter PLMN (public land mobile network) handover in a mobile communication network that shares an E-UTRAN (evolved universal terrestrial radio access network), and a mobile communication system thereof. According to the present invention, the terminal performs E-UTRAN registration through a base station (eNB) and an MME (MME), updates a routing area, activates ISR (idle state signaling reduction), receives a handover command to the previous PLMN or another PLMN and transmits a location update request message to the MME while the handover is being executed. As such, a communication disconnect or any authentication or security failure during the inter PLMN handover of the terminal can be avoided.

    摘要: A security management method in a mobile communication system supporting Proxy Mobile Internet Protocol (IP). In the security management method, a Mobile Node (MN), a Serving Packet Data Service Node (S-PDSN), and an Authentication, Authorization and Accounting (AAA) server generate a security key of the Proxy Mobile IP. Upon receipt of information for authentication of a security key from the MN, the S-PDSN sends an access request message to the AAA server and receives information for verification of the security key. The S-PDSN sends a first message for requesting verification of the security-related key to a Home Agent (HA). The HA verifies the security-related key through the AAA server and sends a second message to the S-PDSN when the security-related key is verified. The S-PDSN sends a message indicating initiation of the Proxy Mobile IP, to the MN.

    摘要: A method for managing mobility of an AT in a mobile communication system using Mobile IPv4. The AAA and the AT generate a first key for mutual authentication between the AT and a HA, and the AAA and the AG generate a second key for mutual authentication between the AG and the HA. The AG generates a third key for mutual authentication between the AG and the AT. The AT acquires a CoA that it will use in a foreign network. The AT sends an RRQ message to the AG. The AG verifies the RRQ message received from the AT, using a third authentication key. The AG then sends to the HA an RRQ message. The HA verifies the AT and the AG, and allocates an HoA of the AT. The HA sends an RRP message including the allocated HoA of the AT in response to the RRQ message.
