By the scheme, a same S-CSCF is ensured to be used in the two User Authentication Request/User Authentication Answer (UAR/UAA) procedures of the initial IMS registration procedure, and the initial IMS registration of the UE is implemented successfully."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for implementing IP multimedia subsystem registration","description":"A method for implementing an IP Multimedia Subsystem (IMS) registration, includes: a Home Subscriber Server (HSS) recording a current registration state of a User Equipment (UE) in response to receivi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514870","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.
