摘要： Common authentication and authorization (AA) between networks having disparate access technologies may enable a seamless user transition between the networks. A set of AA credentials from a user attempting to gain access to one of the networks may be received, and a subscriber database of another of the networks may be used to verify the set of AA credentials. A communication protocol common to the networks may be used. Additionally, the user may employ a single set of authentication and authorization (AA) credentials, usable over multiple communication protocol layers. Further, a user may perform a single authentication and authorization (AA) operation when roaming across two or more networks by gathering user's key material during an AA challenge and reply session at a data link layer. The gathered material may be used for an AA challenge at an upper network layer or another network as the user transitions between networks.

摘要： A mobile station is located and paged for a circuit-switched connection in a GSM system which supports data packet switching (GPRS) services. A table held by the SGSN is provided for locating a mobile station where the mobile has moved from the Routing Area in which it was last located to a cell within the same Location Area which does not support GPRS services. The GSM system comprises a plurality of base station controllers (BSS) serving cells in a Location Area (LA), a circuit-switch control (MSC/VLR) for establishing circuit-switched connections to mobile stations within the Location Area, and a packet control (SGSN) for establishing data packet-switching with mobile stations within one or more Routing Areas (RA) within the Location Area. The packet control, in response to a paging request, consults information from a table held by the packet control of base station controllers which serve cells in the Location Area which are not part of a Routing Area, and instructs base station controllers to page cells in the Location Area and in particular the cells not forming part of a Routing Area.
