The routing information of a C-plane message (routing protocol) received by a U-plane controller is sent to an adjacent peer without being reflected in a routing table of the U-plane controller. The routing table of the U-plane controller is generated on the basis of the routing information (FIB information) received directly from the C-plane controller. In addition, a keep-alive packet from the unified C/U router is not sent to the C-plane controller and keeps alive the connection with the user router at the transmission destination."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system and communication control device","description":"Provided is a communication system which connects a unified C/U router to a network having C/U separation, wherein the stopping of U-plane communication of the unified C/U router is prevented even whe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526437","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.
