In one method, a terminating mobile station receives an INVITE and then, if the access network supports neither simultaneous circuit switched (CS) and packet switched (PS) connections nor voice over internet protocol (VoIP), the terminating mobile station transmits a message indicating that a CS bearer is required for a session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enabling UE access domain selection for terminated speech/video calls","description":"Methods, apparatuses, and systems are described for selecting an access domain for receiving a speech and/or video call at a mobile station of a mobile communications network in which calls are routed","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9730253","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.
