Communication terminal, communication method, and recording medium storing communication terminal control program

A method of communicating with at least one transmission device of a transmission system, the method performed by a communication terminal of the transmission system, the method comprising:

• detecting, by a detector of the communication terminal, a change in an acceleration of the communication terminal when movement of the communication terminal starts or stops, the movement of the communication terminal including an inclination of the communication terminal;
• activating a communication circuit of the communication terminal so as to start receiving location data from the at least one transmission device, the location data indicating a location at which the at least one transmission device is located;
• transmitting, by the communication circuit, the location data and identification information of the communication terminal to the at least one transmission device;
• and
• stopping operation of the detector and the communication circuit after the transmission of the location data and the identification information by the communication circuit is completed.

A non-transitory recording medium storing a plurality of instructions which, when executed by a processor, cause the processor of a communication terminal to perform a method of communicating with at least one transmission device of a transmission system, the method comprising:

• detecting a change in an acceleration of the communication terminal when movement of the communication terminal starts or stops, the movement of the communication terminal including an inclination of the communication terminal;
• activating the communication terminal so as not to receive location data from the at least one transmission device, the location data indicating a location at which the at least one transmission device is located;
• transmitting the location data and identification information of the communication terminal to the at least one transmission device;
• and
• stopping operation of components of the communication terminal after the transmission of the location data and the identification information is completed.
