The method may thereby help to expedite later handover of a call served by the call server from being via the first RAN to being via the second RAN. Further, by the second RAN registration being conducted in response to registration of the device with the call server, the method may help to ensure usefulness of the registration of the device with the second RAN."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Registration with radio access network in response to registration with call server","description":"A method and apparatus in which (i) a user equipment device registers with a first radio access network (RAN) that provides connectivity with a transport network, (ii) once registered with the first R","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9622206","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.
