Abstract
An information transmission method of a mobile reception terminal that is capable of connecting to a server over a network and capable of receiving a direct wave and a reflected wave of radio waves transmitted by a transmission station that has a fixed position and transmits radio waves of a same modulation scheme continuously or periodically, includes: creating a delay profile of reception of the direct wave and the reflected wave that indicates a time difference between the direct wave and the reflected wave; and transmitting the delay profile to the server over the network.
Claims11
An information transmission method performed by a mobile reception terminal that is connected to a server over a network, the information transmission method comprising:
- receiving a direct wave and a reflected wave of radio waves transmitted by a transmission station that has a fixed position and transmits radio waves of a same modulation scheme continuously or periodically;
- creating a delay profile of reception of the direct wave and the reflected wave, the delay profile indicating a time difference between the direct wave and the reflected wave;
- identifying a position of the mobile reception terminal, the position corresponding to the reception of the direct wave and the reflected wave;
- and
- transmitting the delay profile to the server over the network,
- wherein the transmitting includes transmitting, to the server along with the delay profile, information related to the position identified in the identifying, and
- the delay profile is used by the server to calculate a distance between the mobile reception terminal and a reflective object that reflected the reflected wave based on the time difference.
A mobile reception terminal comprising:
- a processor;
- and
- a memory storing a program,
- wherein, the program, when executed by the processor, causes the processor to:
- cause the mobile reception terminal to receive a direct wave and a reflected wave of radio waves transmitted by a transmission station that has a fixed position and transmits radio waves of a same modulation scheme continuously or periodically;
- create a delay profile of reception of the direct wave and the reflected wave, the delay profile indicating a time difference between the direct wave and the reflected wave;
- identify a position of the mobile reception terminal, the position corresponding to the reception of the direct wave and the reflected wave;
- and
- transmit the delay profile to a server over a network,
- wherein the processor transmits, to the server along with the delay profile, information related to the position identified, and
- the delay profile is used by the server to calculate a distance between the mobile reception terminal and a reflective object that reflected the reflected wave based on the time difference.
