The wake-up message bypasses a plurality of network application servers (ASs) to start switching a transition of the terminating UE from an idle state to a connected state before the SIP call initiation message reaches the terminating P-CSCF."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Internet protocol multimedia subsystem (IMS) call setup time booster","description":"A method for decreasing a Call Setup Time Key Performance Indicator (CST KPI) of an Internet Protocol (IP) multimedia call in a mobile telecommunications network includes: initiating the IP multimedia","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11297112","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.
