Link signal setting method for positioning mobile communication terminal

A positioning device comprising:

• a downlink signal receiver configured to receive a downlink signal from a base station;
• an uplink signal receiver configured to receive an uplink signal from a terminal;
• a communication unit configured to transmit a measurement signal obtained by measuring the uplink signal to a position measurement server;
• and
• a controller configured to:
• determine whether the uplink signal receiver performs an operation of detecting the uplink signal from the terminal and whether the communication unit performs an operation of transmitting the measurement signal to the base station or the position measurement server,
• determine a state of the positioning device according to whether the terminal transmits the uplink signal used for positioning or whether the positioning device successfully detects the uplink signal transmitted from the terminal, and
• display state information of the positioning device at a display connected to the positioning device or transmit the state information of the positioning device to a server communicating with the positioning device.

A method for configuring an uplink signal of a terminal by a base station, comprising:

• receive an uplink signal configuration request for a terminal in a standby state from a positioning device or a server communicating with the positioning device;
• generating a state transition signal for instructing a state transition of the terminal in the inactive state and generating a downlink signal for causing the terminal to transmit an uplink signal;
• and
• transmitting the state transition signal and the downlink signal to the terminal.
