Abstract
A synchronization method includes: a first step of transmitting a query command a plurality of times to a communication device configured to perform time synchronization with a base station device connected to a mobile communication network, the query command requesting time information expressed in a first unit, the first unit being lower in accuracy than accuracy of the time synchronization established by the communication device; a second step of determining timing at which the time information obtained in response to the query command is updated; a third step of determining timing to transmit a next query command, based on the timing at which the time information is updated; and a fourth step of acquiring time information with higher accuracy than the first unit, based on time information obtained in response to the query command transmitted at the third step.
