[0061] see figure 2 , figure 2 is a flow chart of a cell handover method provided by an embodiment of the present invention, the method is applied to a source network side device, such as figure 2 shown, including the following steps:

[0062] Step 201. When it is determined that the user terminal needs to perform cell handover, select at least one candidate cell for the user terminal, and send a pre-handover preparation request to the network side device corresponding to the candidate cell.

[0063] The above method can be applied to the source network side device of the user terminal, where the source network side device can be the network side device currently accessed by the user terminal, or can be understood as the network side device to which the serving cell of the user terminal belongs.

[0064] In addition, the above determination that the user terminal needs to perform cell handover may be determined by the source network side device based on the measurement re...

[0073] see image 3 , image 3 is a flow chart of another cell handover method provided by an embodiment of the present invention, which is applied to the source network side device, such as image 3 shown, including the following steps:

[0074] Step 301. Receive a first measurement result reported by the user terminal.

[0075] Wherein, the first measurement result satisfies a preset condition for triggering cell handover, and the first measurement result includes at least one of the following:

[0076] Signal energy information of a serving cell of the user terminal, signal quality information of the serving cell, signal energy information of a neighboring cell of the serving cell, and signal quality information of the neighboring cell.

[0077] In this step, the user terminal may report the reference signal measurement to the source network side device after judging that the first measurement result satisfies the above preset condition. In addition, the above signal en...

[0192] see Figure 8 , Figure 8 is a flow chart of another cell handover method provided by an embodiment of the present invention, the method is applied to a user terminal, such as Figure 8 shown, including the following steps:

[0193] Step 801, when the user terminal needs to perform cell handover, perform air interface measurement, and obtain an air interface measurement result;

[0194] Step 802: Initiate access to the target cell based on the air interface measurement result;

[0195] Wherein, the air interface measurement result is used to determine the target cell in at least one candidate cell, and the at least one candidate cell is the user terminal when the source network side device determines that the user terminal needs to perform cell handover. Selected neighborhood.

[0196] Optionally, before the step of receiving the pre-handover command sent by the source network side device when the user terminal needs to perform cell handover, the method further incl...

Abstract

Provided are a cell handover method, a related device, and a system, the method comprising : when determining that a user terminal needs to implement cell handover, selecting at least one candidate cell for the user terminal, and sending a pre-handover preparation request to a network side device corresponding to the candidate cells; and, on the basis of a pre-handover preparation acknowledgement returned by the network side device corresponding to a target small cell, controlling the user terminal to handover to the target cell, the target cell being a cell selected from the candidate cells on the basis of the results of user terminal air interface measurement.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a cell switching method, related equipment and a system. Background technique [0002] In the current communication system, when a user terminal (User Equipment, UE) performs cell handover, the UE performs measurement reporting according to the measurement parameters configured by the source network side equipment, and the source network side equipment performs the determination process of the target cell based on the measurement results reported by the UE; Then, the source network side device initiates a handover preparation process to the target network side device corresponding to the target cell. After the handover preparation of the target network side device is completed, the source network side device sends a handover command to the UE. The side device initiates access to complete cell handover. In the above technical solution, after the target network ...
