The early session media information is carried in the second SIP message in a form of regular session media information, thus the media gateway control device uses an existing circuit switched bearer to transmit early session media to a first user equipment. The existing circuit switched bearer is established under control of the media gateway control device for a session between the first user equipment and a third user equipment. The SCC AS receives an off-hook signal from the second user equipment, and sends the regular session media information to the media gateway control device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system for service control","description":"In a communication system, a service centralization and continuity application server (SCC AS): receives a first SIP message for establishing an IMS centralized service session; receives early session","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736190","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.
