In the handover method provided in the embodiments of the present application, a notification sent by the CU-CP to the CU-UP not only carries tunnel switching instruction information, but also comprises maintenance instruction information, the maintenance instruction information instructing the CU-UP to continue sending downlink data by means of the original downlink tunnel, such that downlink data can still be received when the user device is not yet connected to a target DU, thereby reducing the interruption time of data transmission during the DU handover process, and enhancing the user experience."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handover method and apparatus","description":"Disclosed in the present application are a handover method and apparatus, relating to the field of communications, and being used for reducing the interruption time of data transmission in a distribut","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11277773","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.
