SWITCHING METHOD AND DEVICE IN ULTRA-DENSE NETWORK

摘要

A handover method and device in an ultra-dense network are disclosed. The method includes the following steps: A source base station sends a first message to a target base station, the first message carries an arrival time indication of a terminal, and the arrival time indication is used to indicate a time at which or a time range in which the terminal is to access the target base station. The source base station receives a second message fed back by the target base station, and the second message carries a granted resource that is allocated for the arrival time indication of the terminal. The source base station adds the granted resource to a command message, and sends the command message to the terminal. The terminal receives the command message sent by the source base station, and sends an RRC connection reconfiguration complete message to the target base station on the granted resource, to indicate to the target base station that the terminal is successfully handed over to, dual-linked to, or multi-linked to the target base station. Such a handover process simplifies an existing handover process, omits an existing random access process of a terminal to a target base station, reduces a handover delay, and improves communication quality.
