US 2003/0145091 A1 · Access terminal profile in a data cellular network

Abstract

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 visitor AN, the subscriber AT profile can be downloaded from the home AAA server to the visitor AAA server, prior to downloading the subscriber AT profile to the visiting AN.

Dependent claims

A data cellular network having a plurality of access networks, each of the plurality of access networks being capable of being in wireless communication with a plurality of access terminals to provide data connectivity between a packet switched data network and the plurality of access terminals during respective data sessions associated with the plurality of access terminals, said data cellular network comprising:

a server associated with only a select one of the plurality of access networks for authenticating the plurality of access terminals involved in respective data sessions via the select s access network, said sever being configured to maintain at least one subscriber profile identifying data services subscribed to by at least one of the plurality of access terminals registered with the select access network, said server further being configured to download said at least one subscriber profile to the select access network upon authentication of the associated at least one access terminal for use by the select access network during respective data sessions associated with the at least one access terminal.

A method for providing data services subscribed to by mobile subscribers within a data cellular network having a plurality of access networks, each of the plurality of access networks being capable of being in wireless communication with a plurality of access terminals to provide data connectivity between a packet switched data network and the plurality of access terminals during respective data sessions associated with the plurality of access terminals, said method comprising the steps of:

storing a session record for a select one of the plurality of access terminals registered with a select one of the plurality of access networks and involved in a data session via the select access network within the select access network;
downloading a subscriber profile identifying data services subscribed to by the select access terminal from a server associated with only the select access network;
and
storing said subscriber profile within said session record for use during said data session.
