According to various implementations, the device proxies a data communication session between an application executing on the device and a remote host over the first RAN, requests data content from the remote host during the session, transfers the session from the first RAN to a second RAN based on the amount of the data content that remains to be received from the remote host during the session and based on a radio-access condition of the first RAN or of the second RAN."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and an apparatus for transferring data communication sessions between radio-access networks","description":"The disclosure is directed to a method carried out on a wireless device capable of communicating over a first radio-access network (“RAN”) using a first radio-access technology (“RAT”) and over a seco","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9591531","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.
