FIELD: communication.
SUBSTANCE: invention relates to a positioning method. Method is designed to be performed by a backbone network device and comprises a step of transmitting a positioning message, wherein the positioning message contains time information used to indicate to the network access device or the terminal device the time for returning the response information. Consequently, the time of each stage in the positioning process is controlled by the reference network device, so that the backbone network device can complete the preparatory operations for positioning during the prescribed time interval.
EFFECT: reduced positioning delay.
