摘要： In a method for providing Location Based Services (LBS) in a mobile communication system, upon receipt of a location trigger at an LS for requesting location information of an MS from a location client, the LS transmits an authentication request message for requesting an ID of an Anchor Authenticator (AA) for the MS to an Authorization, Authentication and Accounting server (AAA), which transmits an authentication response message to the LS. The LS transmits an LCID request message for requesting an LCID of an LC for the MS to the AA, which AA transmits an initiate MS paging request message to an APC. The APC detects a serving LC of the MS and transmits an LCID to the AA, which transmits an LCID response message to the LS, which transmits an MS location report request message to the serving LC. The LC transmits an MS location report response message to the LS.

摘要： Disclosed is an apparatus and method for generating a security key in a mobile communication system that performs security key generation. An Authentication, Authorization and Accounting (AAA) server generates a Master Session Key (MSK) and an Enhanced MSK (EMSK) from a Long Term Credential key, and a Device-MSK (D-MSK), a User-MSK (U-MSK) and a Device and User-MSK (DU-MSK) from the MSK and the EMSK. An Access Gateway (AG) generates a Root-MSK (R-MSK) from the MSK and EMSK received from the AAA server. A Signaling Radio Network Controller (SRNC) generates a Pairwise Master Key (PMK) from the R-MSK received from the AG, and a Traffic Session Key (TSK) from the PMK. A Base Station (BS) sets up a radio connection to a Mobile Station (MS) using the TSK received from the SRNC, and performs radio communication using the set radio connection. The MS generates an MSK and an EMSK, and generates there from a D-MSK, a U-MSK, a DU-MSK, an R-MSK, a PMK, an SRK and a TSK, to perform radio communication with the BS.

摘要： A system for providing LBS in a mobile communication system. An AAA server manages information on an anchor authenticator (AA) of an ASN GW. Upon receipt of a location information service request message from an LBS client, a location information server receives routing information for routing to an AA of an associated mobile station from the AAA server, and transmits a request for location information of the mobile station to the ASN GW. Upon receipt of the location information request from the location information server, a location information controller performs a location estimation procedure between the mobile station and an interconnected base station when the mobile station is in the idle mode, and upon receipt of location information from the base station, transmits the received location information to the location information server.

摘要： Disclosed are a system and a method for performing re-authentication in a communication system. A user Authorization, Authentication and Accounting server transmits a user Master Session Key (MSK_U), which is generated by performing user re-authentication for a mobile station (MS) according to a twice Extensible Authentication Protocol scheme, to a device Authorization, Authentication and Accounting server that generates a new user Master Session Key (MSK_U1) by using the MSK_U and a device Master Session Key generated at initial device authentication for the MS. A base station (BS) generates a Pairwise Master Key (PMK) by using the MSK_U1, and the MS and BS generate an authorization key by using the PMK.

摘要： A method for controlling device triggering in a mobile communication system includes registering a default urgent level of a terminal when the terminal is connected, receiving a device trigger register including urgent level information transmitted from an application server, and setting the received urgent level in a packet filter, and comparing, upon reception of a downlink data packet from the application server, a default urgent level and an urgent level of the application server to determine whether to transmit a downlink data notification. The method further includes receiving a device trigger register including wait time information transmitted from an application server, and then setting the received wait time in the packet filter, and buffering during the wait time upon reception of the downlink data packet from the application server, and then determining a downlink data notification transmission upon expiration of the wait time.
