The method includes: obtaining, by a communications device, a first group identifier of a terminal group to which a first terminal served by a first mobility management entity belongs; and sending, by the communications device, a message related to the first terminal to a second mobility management entity based on the first group identifier when an exception occurs in the first mobility management entity, where the second mobility management entity is a mobility management entity in which a context of the first terminal exists."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication method, communications device, and communications system","description":"A communication method, a communications device, and a communications system to avoid, when an access and mobility management function (AMF) entity fails, a case in which a re-registration process of ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11968743","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.
