The present invention further provides a system and a ringback tone device for providing presence information. According to the present invention, the calling user may obtain the presence information of the called user via a ringback tone to acquire the state and mood of the called user; therefore, the communication experience is improved; the telecom service types are enriched; and the presence service is popularized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for providing presence information using ringback tone","description":"A method for providing ringback tone presence information includes: obtaining a subscription record of a ringback tone presence service corresponding to a user terminal of a call and a routing address","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8515396","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.
