Each of the plurality of extended unique device identifications have the benefit of allowing multiple registrations with one or more access networks while allowing a home subscriber system to detect the one unique device identification embedded in the extended unique device identifications for authentication purposes. Thereby, a large population of deployed UEs and access network infrastructure may benefit without replacement by allowing a UE to maintain session continuity when transitioning between access networks, to select a preferred access technology when in overlapping coverage areas without session interruption, or to maintain multiple sessions (e.g., simultaneous Voice over IP (VoIP) and media streaming) with different access networks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for optimization of SIGCOMP UDVM performance","description":"A mobile communication system that utilizes multiple access technologies achieves multiple session registrations by deriving a plurality of extended unique device identifications from a specific uniqu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8478886","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.
