The application server authenticates the WTRU at least in part by (i) redirecting the WTRU to an identity provider co-located with a network application function (IDP/NAF) and coupled to the BSF via a Zn reference point and (ii) receiving an assertion from the WTRU that the IDP/NAF has authenticated the WTRU based on user security settings retrieved from the BSF by the IDP/NAF over the Zn reference point. After authenticating the WTRU, the application server (i) retrieves user-specific Sh-reference-point-type data from the HSS via the IDP/NAF over the Zn and Zh reference points and (ii) provides the service to the WTRU based on the retrieved user-specific Sh-reference-point-type data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for enabling access to applications integrated with a visited network","description":"An application server receives a request for service from a wireless transmit/receive unit (WTRU) associated with a home network that includes a home subscriber server (HSS) and a bootstrapping server","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621537","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
