Abstract

PURPOSE:To attain incoming call even when the operation of a telephone set is difficult by providing a function inputting information for automatic incoming from a control section to apply setting to the automatic incoming mode and a switching means receiving a code notifying the incoming and changing over an audio line to a MODEM section. CONSTITUTION:A control processor 11 of a transmission/reception section 10 recognizes the code for automatic incoming information of an interface 41 to set the transmission/reception section 10 to the automatic incoming mode. The transmission/reception section 10 awaits an incoming call. When a call comes from a sender afterward, a control section 20 generates a ringing tone or rings a bell. The bell rings several times. The transmission/reception section 10 sends simultaneously an incoming display code notifying the presence of the incoming call to the MODEM section 30 via an interface 41 in order to inform the presence of the incoming call. When the MODEM section 30 in the idle state recognizes the incoming display signal, the section 30 enters the data communication mode. A switch 32 disconnects the connection between audio interfaces 43 and 42 to connect the interface 42 to a MODEM circuit 34, by which the data reception from the section 10 is made possible.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic call termination system in data communication using a mobile radio telephone.

(Prior Art) Mobile radio telephones, such as car telephones, have been proposed in the past. Examples of this kind include, for example, JP-A-49
-130601 and JP-A-5.1-46005. These are devices in which a telephone device is mounted on a car and the telephone communicates wirelessly via a base station.

(Problems to be Solved by the Invention) With a car telephone, if a call is received while the operator is away from his or her seat, the operator must return to the location where the mobile telephone device is located. In addition, when performing data communication or message communication using a telephone in which it is dangerous to take one's hands off the handle, an automatic call receiving system for mobile radio telephones that can automatically receive data while the user is absent or while the mobile unit is in motion. It's all about providing.

(Means for Solving the Problems) The present invention includes a control section that outputs information for automatic reception, a function for inputting information for automatic reception from the control section and setting the automatic reception mode, and a function for setting the automatic reception mode. An automatic call receiving system for a mobile radio telephone, comprising: a transmitting/receiving section having a function of transmitting a code indicating an incoming call when a call is received; and a modem section switching an audio line to a modem upon receiving the code indicating an incoming call. be.

(Function) When the transmitting/receiving section inputs the information for automatic reception from the control section, it sets the automatic reception mode. After that, when there is an incoming call, a code indicating the incoming call is sent to the modem section. The modem section switches the audio line to the modem upon receiving the code indicating the incoming call. In this way, data communication is possible.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention, and is a diagram applied to a public automobile telephone.

In FIG. 1, 10 is a transmitting/receiving section;
It has a control processor 1 for controlling each part of the system. 20 is a control unit having a telephone function for a car phone, and has a key 21 for outputting information. 30 is a modem section, which includes a switch 32, a control processor 33, and a modem circuit 3.
It has 4.

The transmitting/receiving section 10, the control section 20, and the modem section 30 are connected through an interface 4 serving as a path line for transferring signals. Furthermore, the transmitting/receiving section 10 and the modem section 30 are
The modem section 30 and the control section 20 are connected through an interface 42 for audio signals, and the modem section 30 and the control section 20 are connected through an interface 43 for audio signals. interface 4
1 is the I10 port of the transmitting/receiving section 10) Ilo PORT
It is connected to the control sensor 11 via 101 . Interface 42 is connected to audio circuit 102.

Data may be automatically received when the mobile object is temporarily absent from the vehicle or when the vehicle is running.

First, turn on the power switch (not shown) of the car phone,
For example, wake up tone (Wake up'po)
Verify normal operation by audible and visible information using the ne) and display. Thereafter, the key 21 outputs information that is a combination of numbers and characters for automatic incoming calls defined in advance. This key 21 is operated using dial keys or function keys belonging to the telephone function of the control section 20. The information for automatic reception outputted by the key 21 is encoded by an encoder (not shown) included in the control section 20 and sent to the control processor 1 of the transmitting/receiving section 10 via the interface 41.
Sent to 1. The control processor 11 of the transmitting/receiving unit 10 is
The code of the automatic reception information on the interface 41 is recognized and the transmitting/receiving unit 10 is set to automatic reception mode. The transmitting/receiving unit 10 waits for an incoming call. Thereafter, when there is a call from the caller, the control unit 20 sounds a ringing tone or a bell. This bell rings several times (usually twice). At the same time, the transmitting/receiving section 10 sends an incoming call display code to the modem section 30 via the interface 41 to notify the modem section 30 of the incoming call. When the modem section 30, which has been in an idle state, recognizes the incoming call display signal, it enters a data communication mode. In other words, the modem section 3
0, the control processor 33 in the modem unit 30 receives the incoming call display code on the interface via the I10 port 31, and transmits the call to the terminal 36 in a predetermined procedure to the terminal (not shown).
After establishing the link via the switch 32, the switch 32 disconnects the audio interfaces 43 and 42.
The interface 42 connects to the modem circuit 34 and allows data reception from the transmitting/receiving section 10. Switch 32 turns off the ringing tone as soon as it is switched to modem circuit 34.

After completing these sequences, it begins receiving data from the caller. The terminal (not shown) is, for example, a computer, data terminal, f-link, or facsimile machine.

Even if the transmitting/receiving section 10 and modem section 30 of the car telephone are not at hand, as long as the control section 20 is at hand, the automatic call receiving mode can be easily preset from the control section 20 even while driving.

Here, the hook switch signal information is sent to the control processor 11 of the transmitter/receiver 10 via the interface 41ft, but it is provided separately from the interface 41 to transmit hook switch line connection information from the modem unit 30 to the transmitter/receiver 10. It is also possible to send the signal and have the transmitter/receiver unit 1θ connect and disconnect.

Further, the connection and disconnection of the audio line may be performed by the control processor 11 of the transmitting/receiving section 10.

If the above is shown in a flowchart, it will be as shown in FIG.

The above explanation has been made using automatic reception of data communications, but instead of a terminal, a tape recorder or writable memory via a voice processing circuit can be used to automatically receive messages. . Furthermore, the application field is not limited to public car telephones, but also applies to missed communication using multi-channel access (MCA) radios, personal radios, and the like.

(Effects of the Invention) According to the present invention, even when a user is temporarily away from the telephone device or when it is difficult to operate the telephone device, it is possible to receive a call and receive information from the other party.
