Description

Relay method for transmitting vehicle information of vehicle location tracking system using personal mobile communication and repeater

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repeater for transmitting a state of a vehicle together with a position of a personal cell phone equipped vehicle in a vehicle position tracking system using personal cellular communication (PCS and cellular).

A commonly used vehicle location tracking system is a communication system of a taxi call service using a trunk radio system (TRS) as shown in FIG. 1.

The system includes a driving recorder 10 and a taxi call service center 14, a TRS terminal 11 for communication between taxi drivers, a GPS receiver 12 capable of determining the location of a taxi using a satellite, and a reservation. It is composed of a taxi call service center 14 for transmitting and receiving information with a taxi driver through a cellular phone 15 and a TRS network 13 for a call with a customer and managing a taxi call service. In the method of using the system, first, a customer who wants to use a taxi contacts the taxi call service center 14 and reports a boarding location and a telephone number. The taxi call service center 14 receives GPS information of each taxi. Find out the location of the taxi, and call the taxi nearest the location of the customer to inform the customer's phone number and location. At this time, the taxi call service center 14 checks the operation state of the taxi transmitted from the TRS terminal, that is, the presence of passengers and the like and calls only the empty taxis where the passengers do not board. After the taxi is called as described above by making a call with a customer using a cellular phone, the passenger arrives at the place, picks up the passenger and transports it to the destination.

As described above, a taxi communication system has a problem in that a TRS terminal installation cost and a TRS network fee are expensive.

Therefore, a system for tracking the location of a mobile phone holder or a vehicle using a personal mobile communication is currently proposed.

Location tracking in the personal mobile communication network uses a PCS / Cellular communication network having a cell-based network structure as shown in FIG.

In the PCS / Cellular communication network, the personal mobile communication terminal 21 periodically transmits the ID of the base station 22, which is the location information of the cell unit, through the exchange 23, thereby providing a home location register (HLR) and a visitor location register (VLR). Since the registration is performed in the visitor location register 24, the position of the personal mobile communication terminal 21 can be approximately measured using the location information of the registered cell unit without using a GPS receiver.

This particular situation is in the spotlight as a means of easily locating the vehicle without paying the installation and call charges of the conventional TRS terminal, in view of the proliferation of PCS as an essential personal mobile communication in the early 21st century.

However, by this method, it is possible to determine the location of the vehicle, but since the specific information must be obtained in order to check the state of the vehicle, that is, the capacity to carry a passenger or the loading state of cargo, call burdens also exist. As a result, inconvenience may not be improved.

Moreover, in attempting to make a call to inform the central control station of the vehicle status while the vehicle is in operation, there is no movement to solve this problem in any of the proposed methods such as the conventional TRS method even though the driver's surrounding distraction risks.

The purpose of the present invention is to control the operation of the vehicle by automatically transmitting the vehicle status information such as the speed of the vehicle, whether the passenger is on board / cargo, the current state of the vehicle and the occurrence of an emergency to the central control station. All information is to be obtained and processed in a central, real-time, one-touch manner.

The present invention for this purpose can control and manage the vehicle in real time in the service center by connecting the repeater of the vehicle and the service center by using a personal mobile communication terminal using a mobile communication network to periodically and automatically transmit the driving information of the vehicle Provide a means for transmitting information.

The present invention also provides a means for establishing a one-touch central control function by implementing a remote control information transmission function for randomly extracting vehicle driving information from a service center using a network of a repeater and a service center connected as described above. to provide.

In addition, the present invention provides a non-voice communication data transmission means for ensuring stability during operation by allowing the vehicle in operation in response to the command of the central control room to transmit the state of the vehicle in a one-touch manner.
