Embodiment 1

[0029] This embodiment provides a handover method in coordinated multi-point transmission, such as figure 1 As shown, the switching method in the coordinated multi-point transmission includes:

[0030] 101. Before the handover from the source node to the target node is completed, the source node sends CoMP-related information to the target node, where the CoMP-related information includes a coordinated multi-point transmission cooperating set, a coordinated multi-point transmission mode, and A request for coordinated multipoint transmission.

[0031] 102. The source node receives a response sent by the target node to the request for performing CoMP transmission.

[0032] 103. The source node performs CoMP transmission with the target node after the handover is completed according to the target node's response to the request for performing CoMP transmission.

[0033] Wherein, the source node and the target node may be a base station or a cell, but are not limited thereto.

Embodiment 2

[0041] This embodiment provides a handover method in coordinated multi-point transmission between base stations, such as image 3 As shown, the handover method in the coordinated multi-point transmission between the base stations includes:

[0042] 301. Before the handover from the source base station to the target base station is completed, carry the coordinated multi-point transmission related information in the handover request message and send it to the target base station; wherein, the coordinated multi-point transmission related information includes the coordinated multi-point transmission cooperative set, coordinated multi-point transmission The multipoint transmission mode and the request for coordinated multipoint transmission.

[0043] 302. The source base station performs corresponding operations according to the response of the target base station to the request for performing CoMP transmission; if the request is passed, go to 303; if the request is not passed, go ...

Embodiment 3

[0054] This embodiment provides a handover method in coordinated multi-point transmission between base stations, such as Figure 5 As shown, the handover method in the coordinated multi-point transmission between the base stations includes:

[0055] 501. Before the handover from the source base station to the target base station is completed, the source base station sends a signaling message including the CoMP related information to the target base station, where the CoMP related information includes a CoMP cooperating set , a CoMP mode, and a request for CoMP.

[0056] 502. The source base station performs a corresponding operation according to the response of the target base station to the request for performing CoMP transmission; if the request is passed, go to 503; if the request is not passed, go to 504.

[0057] 503. Immediately perform CoMP transmission on the user equipment after the source base station completes handover to the target base station.

[0058] 504. Aft...

Abstract

The embodiments of the invention, which relates to the communication field, discloses a switching method during coordinated multi-point transmission / reception (CoMP) and node equipment, so that a problem that temporary disruption occurs during CoMP after switching from a source node supporting user equipment to a target node is completed during a communication process can be solved. The provided switching method comprises the following steps that: before switching from a source node to a target node is completed, the source node sends information correlated to CoMP to the target node, wherein the information correlated to CoMP includes a CoMP coordination set, a CoMP mode and a request for carrying out the CoMP; the source node receives a response made to the request for carrying out the CoMP and sent by the target node; and after the switching is completed, the source node carries out the CoMP with the target node according to the response made to the request for carrying out the CoMP by the target node. According to the embodiment of the invention, the method and the node equipment are suitable for switching from a source node to a target node during CoMP.

Description
