A first communication terminal on the first LAN issues a registration request to the first relay server while a second communication terminal on the second LAN issues a registration request to the second relay server. The first and second relay servers exchange account information about the registered communication terminals with each other. When the first communication terminal generates communication data addressed to the second communication terminal, the first relay server selects the second relay server as a relay based on the exchanged account information to relay the communication data. Then, the second relay server relays the communication data to the second communication terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Relay-server arranged to carry out communications between communication terminals on different LANS","description":"A technique of carrying out communications between communication terminals on different LANs while realizing reductions in the burden of account control and suppression in load on a server includes fi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472454","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.
