The data is transmitted from the station terminal station side wireless transmission / reception device 9 to the fixed base station via the fixed base station side wireless transmission / reception device 7.

The data transmitted from the fixed base station is not normally stored in the data storage device 10, but is transferred to the base station terminal station side wireless transmission / reception device 9 in the closed space and transmitted to the terminal station.

The tie diversity circuit 15 includes a reception quality detection circuit that detects reception quality such as signal strength or a code error rate, a selection circuit that selects an antenna, or a combination circuit that combines antenna output signals. Since the tie diversity selects or combines the outputs of a plurality of antennas, the reception quality can be improved as compared with the case where only one antenna is used.

Further, the previously described closed space base station 5 shown in FIG. 5 can be used as the closed space base station having the configuration shown in this figure.

By connecting the connection cable of the terminal station, the communication with the base station 5 in the closed space can be performed by wire.

The terminal station connecting connector is individually installed mainly at a place used by the user 12, such as a seat, so that communication can be performed at any seat in the moving closed space 11.

Means, 18a, 18b represent detection signals.

In the figure, the moving closed space 11 is detected by the detecting means 17 installed in front of the fixed base station 1 to communicate next, and the detecting means 17 detects the fixed base station 1 and the moving closed space. The figure shows a state in which the detection signal 18 is transmitted to the base station 5 in the closed space installed in the space 11 and communication is started between the both base stations.

The detecting means 17 is an infrared ray, a laser,
The closed space 11 is detected using radio waves and light. Transmission of the detection signal 18a from the detection means 17 to the fixed base station 1 may be wired, wireless, infrared, laser, light or the like.

Transmission of the detection signal 18b from the detection means 17 to the base station 5 in the closed space also uses radio waves, infrared rays, laser light, or the like. FIG. 9 is a flow chart for explaining the operation of the third example of the above embodiment. Explaining according to the figure, the detecting means 17 constantly monitors the movement (approach) of the closed space, and when detecting the close space, sends a detection signal to the fixed base station and the base station in the closed space.

Upon receiving the detection signal from the detecting means, the fixed base station and the base station in the closed space start communication between both base stations based on the detection signal. Then, the base station in the closed space ends the communication with the fixed base station when it moves out of the area of the fixed base station currently communicating.

By adopting such a configuration, the closed space can be detected early by the detecting means even when the moving closed space moves at high speed and the time for passing through the area of the fixed base station is short. By reducing the load of the fixed base station and the base station in the closed space for detecting the other party, the fixed base station and the base station in the closed space can efficiently communicate with each other.

In the above embodiment, the GPS device 20 is used as the position detecting means in the moving closed space, but other position detecting means include the self-contained navigation system or a combination of GPS and the self-contained navigation system. Are known, and these methods may be used.

FIG. 11 is a flowchart showing the operation of the fourth example of the above embodiment. Hereinafter, description will be given with reference to FIG.

On the other hand, the position data of each fixed base station or the position data of the zone (for example, latitude and longitude) is previously stored in the memory of the base station in the closed space, and this is compared with the data obtained by the GPS device. As a result, the base station in the closed space can recognize whether or not it has entered the area of any fixed base station.

When the closed space reaches the area of a fixed base station, the fixed base station in the closed space starts an operation for communicating with the fixed base station. In response to this, the fixed base station also starts communication, and continues communication while the closed space exists in its own area. Then, when the closed space goes out of the area of the fixed base station, the communication is ended.

FIG. 12 is a diagram showing a fifth example of the embodiment of the present invention.

When the closed space moves, the position data of the closed space is grasped by the movement distance detecting device. (For example, the distance from the reference point) On the other hand, the position data of each fixed base station (for example, the distance from the reference point) is stored in advance in the memory of the base station in the closed space and is obtained by this and the movement distance detection device. By comparing with the data, the base station in the closed space can recognize whether it has entered the area of any fixed base station.

Then, when the closed space reaches the area of a fixed base station, the fixed base station in the closed space starts an operation for communicating with the fixed base station. In response to this, the fixed base station also starts communication, and continues communication while the closed space exists in its own area. Then, when the closed space goes out of the area of the fixed base station, the communication is ended. This example is useful, for example, in the case of a vehicle traveling on a track.

c] install a fixed base station. S ≦ 1000/3600 × t [sec] × v [km / s
ec] + 2 × r [m]

For example, when the fixed base station interval 22 can be expressed by the above equation, the closed space movement speed v is, for example, 200 km / h on the Shinkansen and 150 km / h on the conventional line when the train is a closed space. For an automobile traveling on a highway, it can be determined to be 100 km / h on average.

The fixed base station area radius 24 (r) is, for example, 50 m, 100 m, etc., and is determined by the mobile radio communication system. For example, in the mobile radio communication system in which the fixed base station area radius 24 is 50 m, in order to use the mobile terminal station in the Shinkansen, the fixed base station installation interval 22 of the fixed base stations is set to 1211 m or less in the above formula. As a result, the communication waiting time can be kept within 20 seconds.

When the moving closed space 11 is a train, it is near a curve, a station, etc., and when it is a car, it is a curve, an interchange, a service area, etc. The communication waiting time can be kept within 20 seconds by reducing

According to the above embodiment, near real-time communication is possible and the number of fixed base stations can be small.
