Method and device for virtual cell handover between macro base stations

Abstract

The embodiment of the invention relates to a method and equipment of performing virtual cell switching between macro base stations. The method of performing virtual cell switching between macro base stations includes the steps: sending a first switching request to a target macro base station from a source macro base station for switching user equipment to the target macro base station; giving a response to reception of determination from the target macro base station, indicating the user equipment to switch to the target macro base station, and enabling the user equipment and a virtual cell belonging to the user equipment to maintain connection; sending a second switching request to the target macro base station from the source macro base station so as to switch the virtual cell belonging to the user equipment to the target macro base station; and giving a response to determination from the target macro base station, and indicating the virtual cell to switch to the target macro base station. The method and apparatus of performing virtual cell switching between macro base stations can realize switching of virtual cell between different macro base stations under the current standard; and as switching is performed on different levels, the method of performing virtual cell switching between macro base stations enables data transmission between the user equipment and the virtual cell not to be interrupted during the switching period so as to realize seamless switching.

Description

technical field [0001] Embodiments of the present disclosure relate to the communication field, and more particularly to a method and device for performing virtual cell handover between macro base stations. Background technique [0002] Traffic demands on mobile networks are likely to increase rapidly in the coming years. To meet the above requirements, a possible solution is to deploy very dense networks, such wireless networks are also known as ultra-dense networks (UDN). Currently, virtual cells are considered to handle interference and frequent switching among multiple transmission nodes. In general, a virtual cell consists of a group of small cells (transport nodes) and is dedicated to user equipment. [0003] It is well known that heterogeneous network structures and dual connectivity have broad prospects in future 5G communications. In a heterogeneous network structure, a virtual cell is generated and configured based on the control of a macro base station (MeNB). ...
