Method and apparatus for enabling access to applications integrated with a visited network

摘要

A method and apparatus for interworking between a mobile network operator and an application provider are disclosed. A network application function (NAF) may be co-located with an OpenID provider such that an application server may communicate with the NAF to access a home subscriber server (HSS) via a bootstrapping server function (BSF). The interfaces between BSF and HSS, and between BSF and NAF may be enhanced to carry information that is available through Sh interface between the application server and the HSS. When the WTRU is roaming in a visited network, the application server may communicate with the visited network for charging and policing for serving the service request from the WTRU. The application server may be co-located with an NAF, and may authenticate the WTRU using Generic Bootstrapping Architecture, and may communicate with a BSF in a home network via an eZn-proxy function to access an HSS.

1. A method carried out by an application server using a processor to execute instructions contained in a non-transitory data storage, the method comprising:
the application server receiving a request for service from a wireless transmit/receive unit (WTRU) that is associated with a home network, wherein the home network comprises both a home subscriber server (HSS) and a bootstrapping server function (BSF), wherein the HSS and the BSF are communicatively coupled with one another via a Zh-type reference point; the application server authenticating the WTRU using OpenID, wherein authenticating the WTRU using OpenID comprises the application server:
redirecting the WTRU to an OpenID Provider (OP) that is co-located with a network application function (NAF)(OP/NAF), wherein the OP/NAF and the BSF are communicatively coupled with one another via a Zn-type reference point; andreceiving an assertion from the WTRU that the OP/NAF has authenticated the WTRU, wherein the assertion is based on user security settings retrieved from the BSF by the OP/NAF over the Zn-type reference point; and subsequent to authenticating the WTRU using OpenID, the application server:
retrieving user-specific Sh-reference-point-type data from the HSS via the OP/NAF over (i) the Zn-type reference point between the OP/NAF and the BSF and (ii) the Zh-type reference point between the BSF and the HSS; andproviding the requested service to the WTRU based on the retrieved user-specific Sh-reference-point-type data.
