Abstract

An embodiment of the present invention provides a communication method, network-side equipment, and a user terminal. The method includes: the user terminal is connected to a first base station through a first component carrier, and the first base station sends a preprocessing instruction message to the user terminal to instruct the user terminal Perform uplink synchronization with the second base station on the second component carrier; the first base station acquires the target second base station, sends a first indication message to the target second base station, and instructs the user terminal to perform data transmission with the target second base station.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a communication method, network side equipment, and user terminals. Background technique [0002] Long Term Evolution (LTE for short) is the long-term evolution of the Universal Mobile Telecommunications System (UMTS for short) technical standard formulated by The 3rd Generation Partnership Project (3GPP for short). . In an LTE network, when a user equipment (User Equipment, referred to as: UE) is moving, it moves from an area covered by a base station under the management of a Mobility Management Entity (referred to as: MME) to another base station. In the covered area, hard handover processing is required. [0003] In the prior art, the main working principle of UE performing hard handover is as follows: First, the UE measures the signal strength of the current serving cell, and when the signal strength of the current serving cell is lower than the first...
