ACCESS TERMINAL PROFILE IN A DATA CELLULAR NETWORK

摘要

An Access Terminal (AT) profile for identifying data services subscribed to by a data only (DO) AT or hybrid AT in data mode is stored within a data cellular network, such as a 1xEV DO cellular network. In one embodiment, the subscriber AT profile is stored in a home Access, Authentication and Accounting (AAA) server associated with a home Access Network (AN) of the AT. The subscriber AT profile stored in the home AAA server can be downloaded to the home AN at successful authentication. The current session record in the AN is expanded to include the subscriber profile. In another embodiment, when roaming in a visor AN, the subscriber AT profile can be downloaded from the home AAA server to the visor AAA server, prior to downloading the subscriber AT profile to the visiting AN.
