When the UE is handed over from a PS communication network to a CS communication network, the MSC requests the ATCF controlling the ATGW to bi-casting to both the CS communication network and the PS communication network, and forwarding speech data from the UE to a remote terminal with which the UE is communicating during the PS to CS handover procedure. Once the UE is handed over, the bi-casting and the forwarding are terminated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for improved PS to CS handover of a user equipment","description":"A Mobile Switching Center, MSC, an Access Transfer Control Function, ATCF, an Access Transfer Gateway, ATGW and respective methods therein are provided for performing a packet-switched, PS, to circuit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9622118","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.
