Description

Toll collection method using １ＥＶ－ＤＯ system {Method of collecting a toll by 1xEV-DO system}

The present invention relates to a toll collection system provided by an intelligent transport system (ITS), and in particular, a 1xEV-DO system for using a toll collection service using a 1xEV-DO system supporting high-speed data communication. Toll collection method using a.

1x EV-DO (1x Evolution-Data Only) is Qualcomm's first limited technology, which Qualcomm has named itself as high data rate (HDR) and standardized it as 1xEV-DO.

HDR is Qualcomm's wireless data technology that delivers data rates up to 2.3 Mbps on 1.23MHz CDMA standard voice channels. HDR can be used to improve the data transfer capability in existing CDMA networks or in separate data networks.

In existing CDMA networks, some channels change from voice to data. HDR uses a combination of TDM and CDMA to share each channel with multiple users, but it does not have a fixed time band as in TDMA, but only when needed.

Accordingly, the 1xEV-DO service may be referred to as a system that enables various information data services at high speed.

In addition, ITS installs a roadside base station capable of wireless communication around the road, and installs a vehicle-mounted device capable of communicating with the roadside base station in a vehicle so as to communicate wirelessly, such as a registration number of a vehicle and a vehicle model. Automatic toll collection service that allows to collect the information automatically when passing through the toll road by sending and receiving information, and install the vehicle loading device on the bus to display the bus route and stop area at each stop. It refers to a service that enables various traffic related services such as a bus guidance system that informs passengers of bus arrival time or provides traffic information.

In particular, the current vehicle toll collection system installs a roadside base station at a toll gate on a toll road such as a highway, and analyzes vehicle information transmitted from the onboard device when the vehicle passes, and assigns a toll fee to a credit card of a predetermined vehicle driver. By paying at or transferring from a prepaid card, the vehicle will be collected automatically even if the vehicle passes through the toll gate without stopping.Therefore, it is possible to solve problems such as vehicle delays because the vehicle does not stop for the settlement of the toll gate. It is a service that works.

However, for the current vehicle toll collection, it is possible to install a roadside base station at each toll gate and install a vehicle loading device in the vehicle, and even in the case of a 1xEV-DO system in which users increase continuously, a base station must be separately installed. A roadside base station for vehicle charge collection and a base station for 1xEV-DO service must be installed at the same point to use both services.

Therefore, these methods have a problem of installing two communication systems and a problem of incompatibility between the two systems.

In order to solve the above problems, the present invention does not need to install a separate roadside base station for the vehicle charge collection, it is possible to collect the vehicle charges by using the already installed 1xEV-DO system, thereby reducing the overlapped capital The purpose is to provide a toll collection method using the 1xEV-DO system that prevents waste and provides the driver with more data information services such as geographic information by using the high-speed data service function of the 1xEV-DO system. .

And transmitting terminal information from the 1xEV-DO base station receiving the response message to a message center, searching for a vehicle number corresponding to the terminal information, collecting a fee, and recording a gate passing time of the vehicle. It is characterized by.

Preferably, the response message transmitted from the vehicle terminal,

The vehicle passes through the toll gate and enters and transmits to the next 1xEV-DO base station, thereby predicting the traveling direction of the vehicle.

The vehicle fare collection method using the 1xEV-DO system according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a 1xEV-DO system.

Referring to FIG. 1, a terminal 10 for using high speed data communication through a 1xEV-DO system, a plurality of 1xEV-DO base stations 20 and 21 for wireless communication with the terminal 10, and the plurality of Connected to the 1xEV-DO base station 20 of the central control station 30 to manage, the 1xEV-DO system to manage the overall and the message center 40 to manage message transmission and reception, and terminal identification for vehicle toll collection It includes a number 50 and a billing information database and comprises a server 50 for billing.

The 1xEV-DO system configured as described above provides a high-speed data service required by a user through wireless communication between the terminal 10 and the 1xEV-DO base station 20 and 21 and adds an additional service such as a vehicle fare settlement service according to the present invention. In order to provide a service, the message center 40 is connected to the server 50 to provide various services.

2 is a flowchart illustrating an operation procedure of a toll collection method using a 1xEV-DO system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the 1xEV-DO base station 20 installed in the tollgate for toll collection service periodically broadcasts a vehicle confirmation message to confirm vehicle passing (S101).

When the vehicle passes through the toll gate on which the 1xEV-DO base station 20 is installed, the 1xEV-DO terminal 10 used by the driver of the vehicle receives a vehicle confirmation message broadcast from the base station 20 (S102), The response message is transmitted (S103). At this time, the response message includes the ID information of the terminal, so that the charge is settled.

In addition, the vehicle terminal transmitting the response message leaves the communication area of the 1xEV-DO base station 20 of the toll gate, enters the communication area of the next base station 21, and transmits a response message, thereby allowing the base station 21 to transmit the response message. It is possible to predict the driving direction of the vehicle to enable the fare settlement according to whether the vehicle enters or exits the toll gate.

That is, when the terminal 10 enters the communication area of the next 1xEV-DO base station 21 to perform a handoff process and transmits a response message, the 1xEV-DO base station 21 passes through the toll gate. After confirming the entry, the terminal information for bill settlement is transmitted to the message center 40 via the central control station 30 (S104).

The message center 40 receives the terminal information and accesses the server 50 for fare settlement (S105), retrieves the vehicle information matching the terminal information from the database, collects the fare, and the vehicle passes through the toll gate. One hour is recorded (S106).

By using the 1xEV-DO system as described above, it is possible to collect the toll of the vehicle without the installation of an additional base station by connecting to a server that can collect the terminal information and vehicle information.

In addition, since the base station for the bill settlement is required for each toll gate, the area where the 1xEV-DO service can be increased by installing more base stations, and the vehicle driver by holding the geographic information of the communication area in each base station It is effective to provide various data information such as map information to various services at high speed.

As described above, the toll collection method using the 1xEV-DO system according to the present invention can automatically collect vehicle charges using the 1xEV-DO system for high-speed data service without installing a base station for ITS. By suggesting a method to reduce the capital, the waste of capital due to the installation of the ITS base station can be reduced, and various data services provided by the 1xEV-DO system can be used by the vehicle driver so that the driver can use the geographic information to operate comfortably. Due to the 1xEV-DO base station installed in each toll gate, there is an effect of making the communication area wider.
