Embodiments of the present invention also provide a call establishment device and a call establishment system. Embodiments of the present invention overcome various limits and defects due to the fact that calls between other corresponding terminals can only be established via a particular terminal in each conference room in the prior art, and enable a code stream to be transmitted in the shortest path, thereby greatly reducing the path delay and improving the video conference system scalability."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device and system for call establishment","description":"The present invention, relating to the field of communications, discloses a method, device and system for call establishment, wherein the method includes: obtaining the pre-configured binding relation","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8509410","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.
