For example, if a UE receives a MWI via Non-Access Stratum (NAS) protocol (where NAS protocol serves as a fallback protocol for Session Initiation Protocol (SIP) to deliver the MWI when IMS-based services are unavailable), an IMS restoration procedure may be triggered for the UE where the UE sends a request to register for one or more services of a telecommunication service provider in an effort to restore IMS-based services for the UE, thereby allowing calls to be subsequently established with the UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IMS restoration triggered by receipt of a MWI or a text message via fallback protocol","description":"Internet Protocol Multimedia Subsystem (IMS) restoration for a user equipment (UE) may be automatically triggered in response to the UE receiving a message waiting indicator (MWI) or a text message vi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997146","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.
