The method also includes registering to a Circuit Switched domain associated with Circuit Switched Fallback by tunneling Circuit Switched Registration information, via the eNodeB, to the Circuit Switched domain, thereby enabling the User Equipment to setup a Circuit Switched call or receive a Circuit Switched page. The method also includes receiving a Circuit Switched specific parameter setting from the eNodeB. The Circuit Switched specific parameter setting includes decoding information to facilitate decoding of transmissions in the Circuit Switched domain. Additionally, the method includes, after receiving the Circuit Switched specific parameter setting, switching from the Packet Switched domain to the Circuit Switched domain and using the decoding information to access the Circuit Switched domain."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and arrangement for legacy fallback between communication network systems","description":"A method for handling Circuit Switched Fallback from a Packet Switched domain includes receiving an indication that Circuit Switched Fallback is supported from an eNodeB located within the Packet Swit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736736","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.
