Cell handover method, terminal and network device

Abstract

The invention discloses a handover method, a terminal and a network device. The terminal receives a measurement control message sent by the network device, and measures the indicated cell to be testedto obtain a channel measurement value of each cell, wherein, the cell to be tested at least comprises a candidate cell; If it is judged that any cell triggers other same-frequency measurement eventsbesides the same-frequency measurement event, a designated cell from candidate cells whose channel measurement value is higher than the serving cell is selected according to a preset rule, a measurement report is reported to a network device and a designated cell is monitored, so that the network device determines a target cell from candidate cells whose channel measurement value is higher than aserving cell according to the measurement report, and controls the target cell to send a handover command to a terminal; The terminal receives the handover command from the target cell and handover the serving cell to the target cell using the resource of the target cell according to the handover command. The present application is capable of improving the success rate of reception of handover commands when triggering other co-frequency measurement events other than the co-frequency measurement event.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a cell handover method, and also to a terminal and network equipment. Background technique [0002] In an existing communication system, in order to improve the utilization rate of radio resources and the network capacity of the entire system, a terminal can switch between multiple cells. When the communication quality of the serving cell becomes lower and lower, the network will control the serving cell to send a handover command to the terminal, so that the terminal is handed over to another cell with the best communication quality in the active set. The active set refers to a collection of cells that establish a connection with a certain terminal. The data transmission between the user and the network is carried out through the cells in the active set. [0003] However, since the communication quality of the serving cell is already very poor, when the ...
