Cell phone position measurement system, position measurement method, and cell phone terminal |
摘要 |
In a cell phone position measurement system, a position measurement unit performs position measurement using a (GPS) satellite. A cell phone terminal notifies the position measurement unit of a (GPS) signal received from the satellite and receives a position information service. In the cell phone terminal, a receiving unit receives the signal from the satellite. A radio phone unit notifies the position measurement unit via a radio channel and a cell phone network of position measurement data obtained from the signal received by the receiving unit. A controller controls the radio phone unit and temporarily interrupts communication via the radio channel in position measurement through the receiving unit. A position measurement method is also disclosed.
