TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information communication method including a communication procedure exchanged between a center station and a mobile station at the time of calling.
[0002]
[Prior art]
Conventionally, in an information communication device, when a call is received, it is necessary to determine whether the calling side is a device that handles data communication such as a facsimile device or a personal computer or a device that handles normal voice communication. Is known as a method generally used in a "facsimile apparatus with an answering machine function". This method determines whether the communication is data communication or voice communication based on whether a "special tone" indicating that data communication is to be performed is transmitted from a calling side after an incoming call response is performed once. Was like that.
[0003]
[Problems to be solved by the invention]
However, when the above-described method is used, it is necessary to determine the type of communication after answering once and setting "communication state" or "communication state". For this reason, even when only one of the voice communication and the data communication can be supported, the receiving side terminal has a problem that a communication cost is incurred because the terminal is connected once and responded.
[0004]
Also, especially in a system that does not have an answering machine function, once the terminal is set to the voice communication mode, it becomes clear that a person near the terminal has received a telephone call. When such a method is adopted for a product, there has been a problem that the merchantability is significantly reduced.
[0005]
The present invention has been made in view of the above, and has as its object to confirm whether data communication is possible or not without incurring communication costs. An object of the present invention is to provide an information communication method capable of starting communication.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, when a call is made from a center station for providing a communication service to a mobile station mounted on a vehicle, a terminal of the mobile station is connected to the communication network from the center station. In the information communication method in which an incoming call display signal for notifying an incoming call is transmitted after calling a number, and the mobile station displays an incoming call or sounds an incoming call a predetermined time after the time of the incoming call, the center station includes the communication station. A first transmitting and disconnecting a data communication request signal for requesting data communication within a period in which the mobile station is in a non-ringing display state or a non-ringing state after calling the terminal number of the mobile station to the network; A signal transmission step, a first response step of transmitting a response signal for shifting to data communication when a paging signal is received from the mobile station, and a first communication of starting data communication after the response Process and On the other hand, the mobile station determines whether or not the signal received in response to the call from the communication network is a data communication request signal negotiated with the center station. As a result, when a data communication request signal is received, if data communication with the center station is required, a call is made by calling the terminal number of the center station to the communication network in order to shift to data communication. The gist of the present invention is to include a second signal transmission step of transmitting a signal and a second communication step of starting data communication when a response signal is received from the center station.
[0007]
According to a second aspect of the present invention, in order to solve the above-mentioned problem, the data communication request signal in the first signal transmitting step is configured to transmit an incoming call non-display signal a first time after the transmission of the incoming display signal. The gist is to become
[0008]
According to a third aspect of the present invention, in order to solve the above-mentioned problem, the determining step includes determining in advance the time required from the start of the incoming call display signal received from the center station to the disconnection by the incoming non-display signal with the center station. The gist is to judge whether it is the first time decided between the two.
[0009]
【The invention's effect】
According to the first aspect of the present invention, the center station requests data communication within a period in which the mobile station is in the non-ringing display state or the non-ringing state after calling the terminal number of the mobile station to the communication network. To send a data communication request signal, and disconnect once. Next, when a paging signal is received from the mobile station, a response signal for shifting to data communication is transmitted, and after this response, data communication is started. It is determined whether the signal received in response to the request is a data communication request signal negotiated with the center station, and if the result of this determination is that the data communication request signal has been received, When data communication is required, the terminal number of the center station is called to the communication network and a calling signal is transmitted to shift to data communication. Next, when a response signal is received from the center station, data communication is started.
[0010]
Therefore, it is possible to eliminate communication costs in the process of confirming whether or not data communication is possible prior to “data communication”. In addition, the mobile station can start data communication without being noticed by the occupant of the vehicle while maintaining the silent state, and this method can be used for security products, for example.
[0011]
According to the second aspect of the present invention, the data communication request signal is configured to transmit the non-indication signal after the first time from the transmission of the incoming display signal, so that the data communication is performed prior to the "data communication". In the process up to the confirmation of the feasibility, it is possible to eliminate the communication cost. In addition, the mobile station can start data communication without being noticed by the occupant of the vehicle while maintaining the silent state, and this method can be used for security products, for example.
[0012]
According to the third aspect of the present invention, the time required from the start of the incoming call display signal received from the center station to the disconnection by the incoming non-display signal is the first time previously determined with the center station. By determining whether or not this is the case, it can be determined that this reception is the reception of a data communication request signal, and communication in this case can be used only for data communication.
[0013]

The receiving unit 49 is for outputting the transmitted voice, and includes a receiving circuit 53 and a speaker 55. The transmitting section 51 is for inputting a voice to be transmitted, and includes a transmitting circuit 57 and a microphone 59. The clock unit 67 is a clock for measuring the reception time of the call signal from the center station.
Further, the information communication device 31 includes an information processing unit 61 that transmits position information indicating the current position of the vehicle to a specific destination such as a center station. The information processing section 61 will be described in detail with reference to FIG.
[0016]
Next, FIG. 3 is a diagram illustrating a configuration of the information processing unit 61.
In the figure, the monitoring controller 63 outputs a line connection instruction signal, position information, occupant number information, and the like to the controller 43 according to a control program.

[0018]
Next, the normal operation of the information communication apparatus will be described with reference to (a) a communication control procedure and (b) a timing chart shown in FIG.
At a normal time, when a telephone terminal for general voice communication receives a call to the information communication device 31 provided in the vehicle via the radio base station 25 of the general public telephone network, a duplexer is transmitted from the antenna 33. An incoming call display ON signal (incoming call display signal) is received by the receiving unit 37 via 35 and the incoming call display ON signal is delivered to the control unit 43. The control unit 43 activates the clock unit 67 after receiving the incoming call display ON signal, and blinks the LED on the display unit 45 after 3 seconds (A) as shown in FIG. In addition to notifying the occupant that there is an incoming call, the control unit 43 forms a calling signal, generates a ringing sound (a) from the speaker 55 via the receiving circuit 53 on the handset, and notifies the occupant.
[0019]
That is, as shown in FIG. 4 (b), three seconds after the reception unit 37 receives the incoming call display ON signal (A), the passenger is informed that there is a call from the display unit 45 and the handset. For the first three seconds (A), the ringing tone does not sound. When the ringing tone sounds after the lapse of three seconds, the occupant of the vehicle equipped with the information communication device 31 can recognize that there is an incoming call.
[0020]
Next, when the passenger notices the ringing tone and answers by pressing the handset off-hook or pressing the talk button on the keyboard 47, the ringing tone from the speaker 55 stops and the control unit 43 forms a response signal. This response signal is transmitted from the antenna 33 to the wireless base station 25 via the transmission unit 39 and the duplexer 35. Thereafter, a call can be made using the information communication device 31.
Next, the operation of the information communication apparatus when the vehicle is stolen will be described with reference to (a) a communication control procedure and (b) a timing chart shown in FIG. The information communication device is one to which the information communication method of the present invention is applied.
[0021]
First, when a user of a vehicle equipped with the information communication device 31 proposes that the own vehicle has been stolen at the center station, the center station sends a call to the car telephone of the vehicle registered in the own station. The corresponding terminal number is searched, and as shown in FIGS. 5A and 5B, the terminal number of the vehicle is called, and then the incoming call display ON signal (A) is transmitted. Next, one second later, the incoming call display OFF signal (incoming call non-display signal) is transmitted and disconnected. In the present invention, a data communication request signal for requesting data communication is formed by transmitting an incoming call display OFF signal one second after transmitting the incoming call display ON signal.
[0022]
When there is an incoming call from the center station to the information communication device 31 provided in the vehicle via the wireless base station 25 of the general public telephone network, an incoming call display ON signal is received from the antenna 33 via the duplexer 35. The incoming call display ON signal is received by the unit 37 and passed to the control unit 43. When receiving the incoming call display ON signal, the control unit 43 operates the clock unit 67 to time the receiving time of the incoming call display ON signal.
[0023]
Here, if the incoming call display ON signal from the center station is received and the incoming call display OFF signal is received and cut off one second later, the time from the incoming call display ON signal measured by the clock unit 67 to the incoming call display OFF signal is changed. The reception time (1 second) is passed to the control unit 43.
[0024]
As described above, when the reception time from the incoming call display ON signal to the incoming call display OFF signal is less than 3 seconds, the passenger is not notified of the call from the display unit 45 and the handset. .
Next, since the reception time from the incoming call display ON signal to the incoming call display OFF signal is one second, the control unit 43 determines that the reception time represents a data communication request predetermined with the center station.
Since the information communication device 31 has information to be transmitted to the center station in response to a data communication request from the center station, the information communication device 31 first reads out the terminal number of the center station stored in the RAM unit 75 in advance, and Is transferred from the monitoring control unit 63 to the control unit 43. Next, the control unit 43 forms a call signal (a), and transmits the call signal (a) from the antenna 33 to the wireless base station 25 via the transmitting unit 39 and the duplexer 35.
[0025]
Next, it is determined whether or not a response signal transmitted from the mobile telephone exchange 21 in response to an incoming call of the center station is received by the receiver 37 via the antenna 33 and the duplexer 35, and the line connection is made. Is determined.
When the line is connected, data communication with the center station is necessary, so data communication is continued.
On the other hand, if there is no information to be transmitted to the center station in response to the data communication request from the center station, the information communication device 31 disconnects the communication and returns to the standby state because there is no need for data communication. .
Here, when the data communication is necessary, the monitoring control unit 63 sets the vehicle position information indicating the current position of the vehicle detected by the GPS receiver 73 or the user of the vehicle telephone stored in the internal ROM. Is transmitted to the control unit 43 as communication information, and identification information specifying the number of passengers and the number of passengers indicating the number of passengers in the vehicle are transmitted to the control unit 43. The emergency information (c) is transmitted from the antenna 33 to the center station via the wireless base station 25.
[0026]
Thus, after calling the terminal number of the mobile station to the communication network, the center station issues a data communication request signal for requesting data communication within a period in which the mobile station is in the non-ringing display state or the non-ringing state. Send and disconnect once. Next, when a paging signal is received from the mobile station, a response signal for shifting to data communication is transmitted, and after this response, data communication is started. It is determined whether the signal received in response to the request is a data communication request signal negotiated with the center station, and if the result of this determination is that the data communication request signal has been received, When data communication is required, the terminal number of the center station is called to the communication network and a calling signal is transmitted to shift to data communication. Next, when a response signal is received from the center station, data communication is started.
[0027]
Therefore, in the process up to confirming whether or not data communication is possible prior to "data communication", it is possible to eliminate the occurrence of communication costs in the mobile telephone exchange 21 performing the billing process. In addition, the mobile station can start data communication without being noticed by the occupant of the vehicle while maintaining the silent state, and this method can be used for security products, for example.
Further, since the data communication request signal is configured to transmit the incoming display OFF signal, for example, one second after the transmission of the incoming display ON signal, the process up to confirming whether or not the data communication is possible before the “data communication” is performed. Communication costs can be eliminated. Further, the mobile station can start data communication without being noticed by the occupant of the vehicle while keeping the silent state, and for example, such a method can be adopted for security products.
[0028]
Further, by determining whether the time required from the start of the incoming call display ON signal received from the center station to the disconnection by the incoming call display OFF signal is, for example, one second predetermined with the center station in advance, It can be determined that this reception is the reception of a data communication request signal, and communication in this case can be used only for data communication.
Furthermore, by adopting this information communication method, for example, when a user of a vehicle equipped with the information communication device 31 reports to the center station that his / her vehicle has been stolen, the center station will notify the user that the vehicle has been stolen. It is possible to call the information communication device 31 of the vehicle and confirm the current position of the stolen vehicle without noticing that the stolen vehicle has received an incoming call. Furthermore, the number of persons who have stolen the vehicle can be reported to the center station.
