Abstract
A communication system is formed by a location information providing unit configured to provide a location information indicating a location of each road related facility arranged along a road, and a communication unit installed on each road related facility, configured to transmit the location information of each road related facility to a terminal device of a user on the road by using weak radio signals, such that the terminal device that can receive the weak radio signals can detect a location of the terminal device according to the location information.
Claims15
A communication system, comprising:
- a location information providing unit configured to provide a location information indicating a location of each road related facility arranged along a road;
- and
- a communication unit installed on each road related facility, configured to transmit the location information of each road related facility to a portable terminal device of a pedestrian user on the road by using weak radio signals, such that the portable terminal device that can receive the weak radio signals can detect a location of the portable terminal device according to the location information and utilize a detected location for purpose of acquiring other information related to the location of the portable terminal device.
A communication system, comprising:
- a control unit configured to control a traffic signal on a road to carry out a traffic regulation;
- and
- a communication unit installed on the traffic signal, configured to transmit a traffic regulation information regarding the traffic regulation carried out by the traffic signal to a portable terminal device of a pedestrian user on the road in response to a request from the portable terminal device, such that the pedestrian user can ascertain the traffic regulation carried out by the traffic signal, through the portable terminal device according to the traffic regulation information.
A communication method, comprising:
- providing a location information indicating a location of each road related facility arranged along a road;
- and
- transmitting the location information of each road related facility to a portable terminal device of a pedestrian user on the road by using weak radio signals from a communication device installed on each road related facility, such that the portable terminal device that can receive the weak radio signals can detect a location of the portable terminal device according to the location information and utilize a detected location for purpose of acquiring other information related to the location of the portable terminal device.
A communication method, comprising:
- controlling a traffic signal on a road to carry out a traffic regulation;
- and
- transmitting a traffic regulation information regarding the traffic regulation carried out by the traffic signal from a communication device installed on each road related facility arranged along a road to a portable terminal device of a pedestrian user on the road in response to a request from the portable terminal device, such that the pedestrian user can ascertain the traffic regulation carried out by the traffic signal, through the portable terminal device according to the traffic regulation information.
