Localized authentication, authorization and accounting (AAA) method and apparatus for optimizing service authentication and authorization in a network system

摘要

An authentication and authorization method/apparatus, in a network system which includes a mobile terminal and a home authentication, authorization and accounting (AAA) server, includes: receiving a network access service request signal from the mobile terminal; forwarding the received network access service request signal to the home AAA server which corresponds to the network access service request signal; receiving a service list corresponding to the network access service request signal; and sending a network access service authorization signal to the mobile terminal when the service authorization of the mobile terminal is verified based on the received service list. The single network access service authorization is used for subsequent service authorizations so that the service delay due to the AAA protocol exchanges can be reduced. Delivery of the service list accompanied by an automatic security key generation mechanism achieves local authentication and authorization of local services without involving the home AAA server.
