The UE may send at least one of a requested voice domain preference or a requested RAT preference to a 5G core network (5GC). The UE may also receive, from the 5GC, at least one of a voice domain preference or a RAT preference based on, for example, the capability and compatibility of the UE. The 5GC may additionally generate a RAT/frequency selection priority (RFSP) index for the UE, giving priority to the voice domain preference and/or the RAT preference of the UE. The 5GC may communicate the RFSP index to the RAN. Other aspects, embodiments, and features are also claimed and described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Configuration for legacy voice support in 5G","description":"Aspects of the disclosure relate to systems and methods for configuring a voice domain preference and/or a radio access technology (RAT) preference for a user equipment (UE) in a radio access network ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11974359","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.
