Configuration method of measurement time for terminals, terminal, network side device and system

The invention provides a configuration method of measurement time for terminals, a terminal, a network side device and a system to avoid wasting measurement time and resource and improve scheduling efficiency. The configuration method includes that the terminal informs a network side of measurement capability; and the network side confirms whether the terminal is configured with measurement time or not based on the measurement capability of the terminal. The terminal comprises a measurement capability confirming device and a transmitting device, wherein the measurement capability confirming device is used for confirming and expressing measurement time configuration instructions whether the current terminal is needed to be configured with measurement time, or confirming and expressing system information of the current terminal system; and the transmitting device is used for informing the network side of the measurement capability of the current terminal served by the measurement time configuration instructions or system information. The network side device comprises a receiving device and a decision-making device, wherein the receiving device is used for receiving the measurement capability sent by the terminal; and the decision-making device is used for confirming whether the terminal is configured with measurement time or not based on the measurement capability of the terminal.
