  Here, let us consider the display and reading of a business communication message transmitted from the management center.

  In the conventional technology, a business communication message transmitted from the management center is displayed on the operation indicator mounted on the mobile station (taxi) regardless of the movement of the mobile station (taxi), and the crew member is notified of the reception. For this reason, the incoming buzzer sounded and the incoming business contact message was read out using synthesized speech.

  For this reason, even in the actual vehicle, a ringing buzzer sound or a read-out sound by a synthesized voice has entered the customer's ear, resulting in discomfort to the customer.

  An object of the present invention is to provide a wireless mobile communication system that prevents a customer from feeling uncomfortable when a business contact message transmitted from a management center is displayed on an operation display installed in a mobile station. .

  In order to achieve the above object, the present invention provides a wireless mobile communication system including a base station and a plurality of mobile stations, wherein a business communication message transmitted from a management center is displayed on an operation display mounted on the mobile station. It is characterized by determining whether or not to perform ringing or reading out the displayed contents and determining the dynamics.

  ADVANTAGE OF THE INVENTION According to this invention, when displaying the business communication message transmitted from a management center on the operation indicator mounted in a mobile station, the wireless mobile communication system which does not give a discomfort to a customer can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a concept of a radio communication system according to an embodiment of the present invention, and is a diagram showing a concept of an AVM system for taxi dispatch using GPS.

  In FIG. 1, 110, 111, and 112 represent mobile stations (taxi). In FIG. 1, mobile stations (taxi) 110, 111, and 112 are in normal operation (business) and represent a state where they are performing business in response to instructions from a management center (described later).

  Next, 120, 121 and 122 represent radio base stations of the radio mobile communication system. In general, the radio base stations 120, 121, and 122 have a function of performing two-way communication with a mobile station (taxi) using radio waves and managing radio waves that are limited resources. However, since the range in which the radio wave reaches is limited, for example, the service area in the radio base station 120 where the radio wave reaches 130 is 130. The service area in this case is called a base zone.

  Reference numeral 140 denotes a management center that issues a vehicle dispatch instruction and is connected to the radio base stations 120, 121, and 122 by a dedicated line.

  In addition to these configurations, the mobile stations (taxi) 110, 111, and 112 are equipped with GPS receiving antennas, and the location dynamic information of the mobile stations (taxi) 110, 111, and 112 is assigned to the designated mobile station numbers from the management center 140. Thus, data collection by a polling method for collecting data in the order of mobile station numbers is performed.

  A high-speed digital SCPC (Single Channel Per Carrier) method is used as an example of a commercial wireless communication method between a base station and a mobile station for data collection by a polling method.

  With the recent digitization of commercial wireless systems, the time per cycle required for data collection has been shortened, leading to improved location information accuracy.

  In addition, the mobile station (taxi) is equipped with an operation indicator, which has the function of receiving various information from the radio base station and displaying / reading them.

  Next, the operation of the operation indicator mounted on the mobile station (taxi) that has received the business communication message transmitted from the management center with the above-described configuration will be described.

  FIG. 2 is a diagram showing a device configuration of a mobile station (taxi) according to the embodiment of the present invention, and particularly a diagram showing a device configuration of a mobile station (taxi) configured by a high-speed digital SCPC system commercial radio. is there. In FIG. 2, 210 is a wireless antenna, 220 is a digital wireless device, 230 is an operation indicator, 240 is a car navigation device, 250 is a GPS antenna, and 260 is a toll meter. By turning the engine key to ignition ON, the digital radio device 220, the operation indicator 230, the car navigation device 240, and the charge meter 260 are turned on.

  The wireless antenna 210 receives the business contact message transmitted from the management center, and the digital wireless device 220 detects the content of the business contact message and displays it on the display unit of the operation display 230. In addition, the position information received by the GPS antenna 250 is supplied to the car navigation device 240 to superimpose the position of the mobile station on the map and displayed on the display unit of the operation indicator 230. By operating the operation unit of the operation indicator 230, a business communication message can be displayed, or a map on which the position of the own mobile station is superimposed can be displayed.

  Here, the fee meter 260 has a function of detecting whether the dynamic state is an actual vehicle or an empty vehicle, and the crew member sets these dynamic states. The charge meter 260 transmits a signal indicating the set dynamic state, and the operation indicator 230 receives the signal.

  FIG. 3 is a diagram showing an example of the operation display 230 in FIG. In FIG. 3, the operation display 230 has an operation unit 231 and a display unit 232 for button operation.

  FIG. 4 is a flowchart showing the operation of the mobile station (taxi) that has received the business communication message.

  In step 401, the mobile station (taxi) receives a business contact message from the management center via the receiving antenna 210. Next, in step 402, the mobile station (taxi) determines on the operation display 230 whether the dynamic state of the mobile station (taxi) is an empty vehicle or an actual vehicle. In the case of an empty vehicle, in step 403, the mobile station (taxi) displays a business contact message on the display unit 232 of the operation display 230 and reads out the received business contact message by a synthesized voice.

  In the case of an actual vehicle in step 402, the mobile station (taxi) displays a business communication message on the display unit 232 of the operation display 230 in step 404, but an incoming buzzer sounds to inform the crew member that it has been received. In addition, the incoming business contact message is not read out by synthesized speech.

  Next, in step 405, the mobile station (taxi) determines whether or not the dynamic state of the mobile station (taxi) has become an empty vehicle by using the operation indicator 230. If the vehicle is not empty, step 405 is repeated at regular intervals. If the vehicle becomes empty, in step 406, the incoming business contact message is read out by synthesized speech in order to inform the crew of the reception. By this, when the customer gets off, the crew can notice that the business communication message has arrived.

  Note that the business communication that has not been read out in the actual vehicle in step 403 is automatically read out in step 406 when moving to step 405 and detecting the dynamics of the empty vehicle. However, there are cases where the reading is not automatically read out, for example, when the display screen is switched by receiving some operation or individual call.
