In order to achieve the above-mentioned object, an operation state notification system according to the present invention is provided by installing a mobile communication base station device at each of a plurality of stops arranged on an operation route of a business vehicle. Each of these mobile communication base station devices forms a wireless area along an operation route.
On the other hand, the commercial vehicle is equipped with a mobile communication terminal, and when the commercial vehicle enters the above-mentioned wireless area, this entry is detected by the mobile communication terminal, and the identification information of the mobile communication base station device is identified on the operating route by the mobile communication terminal. Is transmitted to the operation management device as information representing the position. Then, the operation management device recognizes the operation state of the business vehicle including the position on the operation route of the mobile communication terminal based on the identification information of the mobile communication base station device coming from the mobile communication terminal, and recognizes the recognized operation state. The notification information indicating the operation state is transmitted to the mobile communication base station device at the stop located in the traveling direction of the business vehicle and displayed.

Therefore, according to the present invention, the operation management device recognizes the position of each business vehicle using the mobile communication base station device installed at each stop and the mobile communication terminal mounted on each business vehicle. It is possible to display the operating state of the commercial vehicle at each stop in the traveling direction based on this position information. That is, for example, by using a general-purpose base station and a mobile communication terminal used in a PHS or the like, it is possible to recognize the position of the business vehicle and report the information to a stop. For this reason, it is possible to provide a system that is extremely inexpensive and easy to maintain as compared with a case where a dedicated communication infrastructure and a communication device are installed as in the related art.

[0007] The present invention is also applicable to a case where a mobile communication terminal enters a wireless area formed by the existing mobile communication base station device when the existing mobile communication base station device is arranged between the stops. It is also characterized in that the identification information of the existing mobile communication base station device forming the wireless area is transmitted to the operation management device as information for notifying its own position on the operation route.

[0008] In this manner, the operation management device can recognize the position of each business vehicle not only in the unit of the stop but also between the stops, thereby enabling more detailed management of the operation state. It becomes possible.

Further, the present invention provides a mobile communication terminal having a route database in which identification information of a plurality of mobile communication base station devices is stored in advance in the order of operation routes, and when the mobile terminal detects its own entry into an arbitrary wireless area, Acquiring identification information from a mobile communication base station device forming the wireless area,
When the identification information matches the storage information in the route database, the acquired identification information is transmitted to the operation management device as information representing the own position.

[0010] By doing so, even if identification information is received from a base station located off the operating route, the identification information is erroneously transmitted as information indicating its own position. As a result, it is possible to always notify an accurate operation state along the operation route.

Further, as a method of transmitting information indicating the position of a commercial vehicle, a method of transmitting the information to an operation management device via a mobile communication base station device forming a wireless area where a mobile communication terminal has entered, and a communication network When a packet network is provided, there is a method in which a mobile communication terminal generates a packet in which identification information of a base station device is inserted, and transmits the packet to an operation management device via the packet network.

The former has an advantage that it can be easily transmitted without using a special protocol conversion or the like, while the latter has an advantage that it can be transmitted at high speed and at a low communication fee by using a packet.
