Method, system and device for switching user equipment (UE) among nodes on network side

Abstract

The invention discloses a method, a system and a device for switching user equipment (UE) among nodes on a network side, which are used for solving the problem that coordinated multi-point (COMP) transmission continuity cannot be ensured when the UE is switched among the nodes on the network side in the prior art. The method comprises the following steps that: a target node on the network side receives switching request information sent by a source node on the network side where the UE is positioned, determines a COMP cooperation set of the UE in the target node on the network side according to at least one piece of attribute information of the UE carried in the switching request information, and determines at least one node on the network side in the COMP cooperation set, so that the at least one node on the network side performs COMP data transmission with the UE. In the embodiment of the invention, the attribute information of the UE with the COMP cooperation set to be determined is carried in the switching request information, so that the target node on the network side quickly determines the COMP cooperation set of the UE according to the attribute information of the UE and the COMP transmission continuity in the switching process can be ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, system and device for realizing handover of user equipment between network side nodes. Background technique [0002] In the next-generation mobile cellular communication system (Long Term Evolution-Advanced, LTE-Advanced) system, the coverage of high data rate can be increased through the coordinated multi-point (Coordinated Multi-point, COMP) transmission and reception technology, thereby improving the network side node edge The throughput and increase the throughput of the system, therefore, some services at the edge of the network can only be provided by using COMP. [0003] The coordinated multi-point transmission and reception technology refers to multiple transmission points (different network side nodes) that are geographically separated, and cooperate to participate in the transmission or reception of data for a user equipment (User Equipmen...
