Embodiment 1

[0267] Embodiment 1: Two-step handover success process, wherein the handover command includes multi-cell information (such as cell ID and configuration information used by the terminal to send and receive dedicated data in the cell).

[0268] Such as Figure 8 As shown, the first method for successful two-step handover in the embodiment of the present invention includes:

[0269] Step 1: The network-side device managing cell1 decides to handover the terminal to one of the target cells cell2 and cell3 through the terminal measurement report information in cell1.

[0270] A handover preparation process is initiated between the network side device and the devices that manage cell2 and cell3, and succeeds.

[0271] Wherein, the devices managing cell2 and cell3 respectively provide configuration information for the UE to access the cell.

[0272] Step 2: The network side device sends the first handover command through an RRC message, which carries the information that the target ...

Embodiment 2

[0277] Embodiment 2: A process in which the two-step handover fails but rolls back successfully, wherein the handover command includes multi-cell information (such as cell ID and configuration information used by the terminal to send and receive dedicated data in the cell).

[0278] Such as Figure 9 As shown, the first two-step handover failure fallback success method in the embodiment of the present invention includes:

[0279] Step 1: The network-side device managing cell1 decides to handover the terminal to one of the target cells cell2 and cell3 through the terminal measurement report information in cell1.

[0280] A handover preparation process is initiated between the network side device and the devices that manage cell2 and cell3, and succeeds.

[0281] Wherein, the devices managing cell2 and cell3 respectively provide configuration information for the UE to access the cell.

[0282] Step 2: The network side device sends the first handover command through an RRC mess...

Embodiment 3

[0291] Embodiment 3: The process of connection re-establishment after two-step handover fails, wherein the handover command includes multi-cell information (such as cell ID and configuration information used by the terminal to send and receive dedicated data in the cell).

[0292] Such as Figure 10 As shown, the first two-step handover failure connection reconstruction method in the embodiment of the present invention includes:

[0293] Step 1: The network-side device managing cell1 decides to handover the terminal to one of the target cells cell2 and cell3 through the terminal measurement report information in cell1.

[0294] A handover preparation process is initiated between the network side device and the devices that manage cell2 and cell3, and succeeds.

[0295] Wherein, the devices managing cell2 and cell3 respectively provide configuration information for the UE to access the cell.

[0296] Step 2: The network side device sends the first handover command through an ...

Abstract

The embodiment of the invention relates to the technical field of wireless communication and particularly relates to a switching method and device, so as to solve the problem that the switching mechanism in the prior art can not ensure the switching command sending success rate. In the embodiment of the invention, a network side device sends a first switching command containing at least one pieceof cell information to a terminal; cell information is selected from cell information notified to the terminal according to the communication quality of the terminal; and the terminal is notified by asecond switching command notification to perform cell switching according to the cell information in the first switching command selected by the network side device. As the cell information is firstly sent to the terminal, the terminal only needs to be notified which cell information is selected by the network side in the case of switching, the switching command length is thus reduced, and the switching command sending success rate is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for switching. Background technique [0002] Ultra-dense networking is a trend in the development of mobile communication systems in the future. In the case of ultra-dense networking, in order to achieve unified control plane management for a large number of distributed processing nodes, it is necessary to centralize some protocol functions. In this way, a double-layer structure of centralized processing nodes and distributed processing nodes is formed. The distributed processing nodes are also called TRP (Transmission Reception Point, sending and receiving nodes), and the centralized processing nodes also become CU (CentralUnit, centralized processing nodes) or NR eNB (New RAT eNB, new access technology base station). [0003] For the centralized processing node, according to different functions, it can be further divided into a contro...
