Abstract

An authentication method for CDMA user roaming to GSM, when the user calls for authentication in GSM network, before sending authentication three parameters group to GSM MSC / VLR, the GSM 1X sends an authentication request to CDMA HLR / AUC, the field of access type in the request designates the user's current access network is GSM, after receiving this authentication request, CDMA HLR / AUC judges that the access type of the user is GSM access, tags the access type of the user as GSM access, and sends back an authentication success response to the GSM 1X. CDMA HLR / AUC sends back an authentication fault response to the GSM 1X, when CDMA HLR / AUC does not grant the user permission to access the GSM network. The present invention makes CDMA user access GSM network facilely.

Description

technical field [0001] The invention belongs to the roaming technical field of CDMA and GSM, and specifically relates to a method for authenticating a CDMA user roaming to a GSM network. Background technique [0002] In order to solve the needs of CDMA users roaming to GSM networks and GSM users roaming to CDMA networks, 3GPP2 proposed the IIF standard (N.S0028 protocol), adding a device between the CDMA and GSM networks for communication between the two networks Mapping and transformation of order and business. China Unicom's specification is called GGG (GSM 1XGLOBLE GATEWAY). For the convenience of description, this article is collectively called GSM1X. [0003] When a CDMA user roams to a GSM network, the GSM1X device acts as a gateway. When a CDMA user accesses a GSM network, the GSM1X acts as a GSM HLR / AUC (Home Location Register / Authentication Center), and the GSM MSC currently visited by the user / VLR (mobile switching center / visitor location register) completes use...
