If the subscriber is authenticated and the subscriber identification is already stored in the proxy server, the proxy server assigns a group-specific mobile key to the subscriber identification. When the home agent receives a registration request message originating from a subscriber terminal and containing a subscriber identification and transmits a key request message, containing the subscriber identification, for a mobile key to the proxy server, if the subscriber identification in the key request message matches a subscriber identification stored by the proxy server, a mobile key for cryptographic protection of mobile signalling messages is provided to the home agent by the proxy server."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and server for providing a mobile key","description":"After a radio link is established between a mobile subscriber terminal and an access network, the subscriber is authenticated by a proxy server of an intermediate network forwarding, from the access n","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8477945","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.
