Abstract

The invention discloses cell handover control methods, a cell measurement method, equipment and a system. One cell handover control method includes: acquiring terminal information; and after receiving a random access request transmitted by a terminal, beamforming a random access response corresponding to the random access request according to the terminal information, and transmitting the random access response to the terminal. The random access response includes configuration information of resources which are required for communication by the terminal after the terminal is handled from a source cell covered by a source base station to a target cell covered by a target base station. Cell handover success rate of the terminal is increased by the cell handover control methods, cell measurement method, equipment and system.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a control and measurement method, device and system for cell handover. Background technique [0002] In the Long Term Evolution Advanced (LTE-A for short) communication system, a low power node (Low Power Node, LPN for short) is introduced, and the low power node and the macro cell node together form a heterogeneous network. In heterogeneous networks, the main purposes of low-power nodes are: coverage enhancement, capacity increase, improvement of edge user communication quality, group mobility and temporary network deployment, and cost reduction. The introduction of low-power nodes has changed the topology of the original communication system, so it is of practical significance to study new features in heterogeneous network scenarios. [0003] The process of cell handover by a terminal (also referred to as user equipment, User Equipment, ...
