KR970068259A - A visiting site authentication center for mutually authenticating mangles having mutually different authentication procedures, and mutual authentication methods of mutually different mangans using the same - Google Patents

Abstract

The present invention relates to a landmark authentication center for mutually authenticating mangles having mutually different authentication procedures such as a CDMA (Code Division Multiple Access) network and a GSM (Group Special Mobile) network, and a mutual authentication method for mutually different manganese using the same. A CDMA subscriber is connected to a CDMA (Code Division Multiple Access) network 101 and a GSM (Group Special Mobile) network 103 and has a function for performing a GSM authentication procedure and a function for performing a CDMA authentication procedure, When the GSM subscriber moves to the network 103, the subscriber authentication data is relayed between the GSM system and the CDMA authentication center. When the GSM subscriber moves to the CDMA network 101, the authentication data obtained in the GSM system is temporarily stored, And a landing site authentication center that operates as an authentication center of a GSM subscriber and performs authentication of a GSM subscriber, The authentication can be performed within a short period of time, leakage of imports can be prevented, and call quality can be improved.

Claims (7)

A CDMA subscriber is connected to a CDMA (Code Division Multiple Access) network 101 and a GSM (Group Special Mobile) network 103 and has a function for performing a GSM authentication procedure and a function for performing a CDMA authentication procedure, The subscriber authentication data is relayed between the GSM system and the CDMA authentication center when the subscriber moves to the GSM network 103. The GSM subscriber stores the authentication data obtained in the GSM system when the GSM subscriber moves to the CDMA network 101, Wherein the gateway is configured to operate as an authentication center of a GSM subscriber to perform authentication of a GSM subscriber. 2. The system according to claim 1, wherein the landmark authentication center (102) comprises subscriber authentication data residing in the main memory and received from the GSM system when the GSM subscriber moves to the CDMA network (101) A database 201 for storing subscriber data such as authentication data of a CDMA subscriber; A database management unit (202) for managing the database (201) in real time; Such as a CDMA map (MAP) and a MAP authentication request (MAP-Athentication-Info-Request), such as an authentication request, an authentication directive request and a security status report, An application service unit 203 for processing MAPs; A signal processing unit 204 for transmitting a map (MAP); And an operation management / maintenance unit (205) for processing functions related to an operator interface and system management for system operation. A method for a GSM system to authenticate a CDMA subscriber when a CDMA subscriber is moved to the GSM network 103, wherein when a CDMA subscriber requests a location registration with the GSM system when moving to the GSM network 103, a GSM visitor location register (VLR) A first step (301 to 303) of requesting subscriber authentication data to a CDMA authentication center through a visiting place authentication center (102); A second step (304,305) for generating and transmitting subscriber authentication data to the GSM visitor location register (VLR) through the visited location authentication center (102); And a third step (306) of performing authentication for a CDMA subscriber in a GSM authentication procedure. 4. The method of claim 3, further comprising determining whether the authentication is successful after performing the authentication for the CDMA subscriber, performing location registration if the procedure is successful, and, if the authentication procedure is unsuccessful, ≪ / RTI > further comprising steps (307 through 309). When the GSM subscriber requests location registration to the CDMA system when moving to the CDMA network 101, the CDMA Visitor Location Register (VLR) sends the authentication request message to the visited location authentication center 102 (Step 401-403); A second step (404 to 406) for generating authentication data and transmitting the authentication data to the visited location authentication center (102) when the visited place authentication center (102) requests authentication data in the GSM system; And a third step (407) of authenticating the GSM subscriber with a unique attempt procedure using the authentication data received from the GSM system. 6. The method of claim 5, further comprising determining whether the authentication is successful after performing the GSM subscription authentication, and if the authentication procedure is successful, the CDMA system performs location registration of the GSM subscriber, and if the authentication procedure fails Further comprising a fourth step (408-410) of rejecting the location registration. The method of any one of claims 5 to 6, wherein the first step (401 to 403) comprises the step of, when a GSM subscriber moves to the CDMA network (101), the GSM subscriber (401, 402) of requesting location registration to the CDMA system by creating an authenticator and placing it in a location registration request message; And the VLR receiving the location registration request transmits an authentication request message to the visiting authentication center (hereinafter, referred to as " home location registration center ") to perform authentication using a random number and an authenticator, 102). ≪ / RTI > ※ Note: It is disclosed by the contents of the first application.
