The method of the embodiments of the present invention comprises: a UE receives a DRB reconfiguration message from a macro base station; and the UE keeps a PDCP layer corresponding to all of the DRBs of a control side and of a user side at the macro base station, and switches other layers corresponding to some or all of the DRBs of the user side except the PDCP layer onto at least one base station. Because the embodiments of the present invention reduce the number of times of control side switching by the UE, in the case of increased frequency and number of times of switching by the UE in the E-UTRAN network architecture, the risk of communication interruption is reduced when the UE is switching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, system, and device for switching","description":"Embodiments of the present invention relate to the technical field of wireless communications, and specifically relate to a method, system and device for switching, for use in solving the problem in t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9749903","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.
