The present invention relates to a method of using a call, billing, and navigation using a multi-function mobile communication terminal, and more particularly, to an automatic mode change method from when a mobile communication terminal is mounted in a vehicle to being detached.

In general, in order to use toll roads such as highways, a fee must be paid. Toll gates (hereinafter referred to as 'highway toll gates') are installed at the entrance and exit of the road. Since the toll collection method implemented at these toll gates was performed manually by a booth manager (toll collector) at each lane of entry and exit, congestion at entrance and exit was inevitable, resulting in road use. Along with the deterioration of efficiency, the waste of oil costs was caused.

To solve this problem, the Tollgate fare settlement system, a so-called 'high pass' (quoted from the Korea Expressway Corporation) is currently being implemented in some lanes. With reference to the accompanying Figures 1 and 2 schematically as follows.

The lane 1 of the toll gate illustrated in the figure is provided with a gantry 10 which is one of road side equipment (RSE). The gantry 10, which is connected to a server (toll payment server, not shown) of the toll gate payment system, includes a transmit / receive antenna 12 in the RF method and a transmit / receive sensor 12 in the IR method.

As illustrated in FIG. 2, an on-board unit (OBU: On_Board Unit) is installed on the front glass or the dashboard of the vehicle C1 entering the lane 1. The onboard vehicle OBU calculates the toll wirelessly through the gantry 10 of the toll settlement server, and the settlement information is updated and stored in a smartcard of the onboard vehicle OBU.

However, smart cards and vehicle-mounted vehicles (OBUs) are separate devices for toll settlement, requiring users (or drivers) to pay for purchases and are not scalable in terms of functionality.

The smart card provided in the vehicle-mounted vehicle (OBU) may be used in parallel with the above-described 'high pass' and 'touch pass' methods (quoting service names being implemented by Korea Expressway Corporation). More specifically, the lane 2 (exit lane) of Fig. 1 is provided with a touch path device 20 that can communicate with the smart card in a contact or non-contact manner. This touchpath device differs only in communication method, and performs the function of the aforementioned gantry. The driver of the vehicle C2 entering the lane 2 receives the toll fee by approaching or contacting the smart card with the touch path device.

In addition, recently, technology for performing a payment settlement using a mobile communication terminal rather than a smart card has been disclosed, and technology development for utilizing this has been made.
