Localized authentication, authorization and accounting (AAA) method and apparatus for optimizing service authentication and authorization in a network system
First Claim
1. An authentication and authorization method in a network system which includes a mobile terminal and a home authentication, authorization and accounting (AAA) server, the method comprising:
- 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.

Abstract
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.

11. A network system, comprising:
-
a local authentication, authorization and accounting (AAA) server to receive a network access service request signal from a mobile terminal and forward the received network access service request signal according to information corresponding to the mobile terminal sending the network access service request signal; and
a home AAA server to receive the forwarded network access service request signal and send a service list corresponding to the network access service request signal to the local AAA server, wherein the local AAA server sends 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. An authentication and authorization method in a network system which includes a mobile terminal, a local authentication, authorization and accounting (AAA) server and a home AAA server, the method comprising:
-
receiving, by the local AAA server, a network access service request signal from the mobile terminal;
forwarding, by the local AAA server, the received network access service request signal to the home AAA server which corresponds to the network access service request signal;
receiving, by the AAA local server from the home AAA server, a service list corresponding to the network access service request signal; and
sending, by the AAA local server, 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. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. An authentication and authorization method in a network system, the method comprising:
-
sending a network access service request signal from a mobile terminal;
receiving a single network access service authorization comprising a service list in response to the network access service request signal; and
sending, for an initial and for any subsequent service authorization of the mobile terminal, a network access service authorization signal to the mobile terminal based upon the single network access service authorization, when the service authorization of the mobile terminal is verified based on the received service list.
