A specific solution is: A first device receives first discovery information sent by a second device, adds an ID of the first device to the first discovery information, and sends the first discovery information to which the ID of the first device is added, so that a destination device can determine a transmission path after receiving the first discovery information. The present invention is used for path selection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Path selection method, device, and system","description":"The present invention relates to the communications field, and discloses a path selection method, a device, and a system, to resolve a problem in the prior art that if a distance between two terminal ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10477453","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.
