Abstract

PURPOSE:To attain talking by adopting the system such that the hand-free talking mode is automatically selected when the operator does not reply an arrived call even with a prescribed number of times of ringing by a tone ringer signal. CONSTITUTION:The system is provided with an antenna 3 sending/receiving a radio wave, a radio equipment 4 controlling the connection of a telephone line, a handset 5 and a cradle 6 on which the handset 5 is placed. Moreover, the system is provided with a hand-free switch 7 with a hand-free talking start and end button fitted in the vicinity of a steering wheel 2, a speaker 8 sounding a received voice at the hand-free talking, and a microphone 9 collecting the transmission voice at hand-free talking. When the operator does not reply a call even while a prescribed number of times a tone ringer signal (call signal) is outputted, the system is devised so as to be brought into the hand-free talking mode automatically. Thus, the driver devotes itself on the driving at the arrival of a call and the mode is automatically transited to the talking mode.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a hands-free device that allows the caller to make a call without holding the handset in his/her hand even when the caller receives a call while driving.

[Conventional technology]

Conventionally, this type of car telephone system has a configuration as shown in FIG. FIG. 1 is a block diagram of a car telephone system according to the present invention, which will be described later, and since the structure is the same as that of a conventional system, the conventional system will be explained using FIG.

In FIG. 1, 1 is a car, 2 is a steering wheel, 3 is an antenna that transmits and receives radio waves, 4 is a radio device that controls the connection of a telephone line, 5 is a handset, and 6 is a pedestal on which the handset 5 is mounted. The pedestal 6 contains a circuit for switching between handset and hands-free calls.

In addition, 7 is a hands-free switch with a hands-free call start and end button attached near the handle 2,
8 is a speaker that outputs incoming audio during hands-free calls;
Reference numeral 9 denotes a microphone that collects the transmitted voice during a hands-free call.

Next, the operation will be explained using the flowchart shown in FIG. FIG. 3 is a diagram showing a flowchart when a call is received in the car telephone system configured as shown in FIG.

First, in step 5301, it is determined whether there is an incoming signal. If there is no incoming signal, the process returns to step S301 again from the NO side, and it is determined whether there is an incoming signal.

If the incoming signal matches in step 5301, YES
Proceed to step 5302 from the side, this step 5302
Then, the operator will decide what action to take.

When the operator lifts the handset 5 in step 5302, the handset 5 enters the transmitting/receiving 111 call mode in step 5303, and a handset conversation is performed.

To end the conversation using the handset, the handset 5 is placed on the stand 6 as shown in step 5304, and the conversation ends in step 5305.

Furthermore, if the operator presses the hands-free start button of the hands-free switch 7 in step 5302,
From the B side of step 5302, the hands-free call mode of step 5306 is entered, and a hands-free call is performed.

To end the hands-free call, the hands-free end button of the hands-free switch 7 is pressed as shown in step 5307, thereby ending the call in step 5305.

Furthermore, if the handler presses the response hold button on the handset 5 in step 5302, step 5
The C side in step 302 enters the response hold mode in step 8308, and the telephone office makes an announcement to the other party that "you are currently unable to respond."

If the operator picks up the handset 4115 during the response hold mode of step 8308, the handset conversation mode of step 5303 changes from the A side of step 5309.

The operations after the transmitter/receiver call mode in step 5303 are the same as those in step 5302 described above.

If the operator presses the hands-free start button of the hands-free switch 7 during the response hold mode in step 5308, the B side in step 5309 becomes the hands-free call mode in step 8306. The operations after the hands-free call mode in step 5306 are as described above.

Further, if the handler presses the call end button attached to the transmitter/receiver 815 during the response hold mode in step 3308, the call ends in step 5305 from the B side in step 5309.

[Problem R that the invention attempts to solve]

Conventional car phone systems are configured as described above, so if a call arrives while driving, the operator must perform some operation to make the call. There was a problem in that users had to operate the telephone while talking, which could create a dangerous situation.

This invention has been made to solve the above-mentioned problems, and aims to provide a car telephone system that allows a driver to concentrate on driving when a call is received, and that automatically shifts to a call mode.

(Means for Solving the Problems) The car telephone system according to the present invention automatically switches to a hands-free call mode when a call is received and the operator does not perform any operation even after the tone ringer signal (calling signal) rings N times. It was made so that it would become so.

[For production]

In the car telephone system of the present invention, if the operator does not perform any operation even after the tone ringer signal rings N times when a call is received, it is determined that the operator cannot perform the operation, and automatically puts the system into a hands-free call mode.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a car telephone system according to the present invention will be described below with reference to the drawings. The configuration of the car telephone system in this case is as shown in FIG. 1, and repeated explanation here will be omitted. The differences from the conventional method will be explained using the flowchart in FIG. 2. In FIG. 2, step 510
1 determines whether there is an incoming signal.0 If there is no incoming signal, the process returns to step 5101 again from the NO side, and it is determined whether there is a multiplied signal.

Also, if there is an incoming signal at step 5IOI,
If the answer is YES, the process advances to step 5102.

In step 5102, it is determined whether the operator has taken any action before the tone ringer signal (calling signal) rings N times (for example, 5 times).

If the handler takes any action, step 51
If 02 is YES, it is determined in step 5I03 what the corresponding means is.

When the corresponding means are A: lifting the handset, B: pressing the hands-free start button, and C: pressing the response hold button, steps 5104, 5107, and 5109 respectively.
Proceed to.

Since the steps after step 5103 are the same as the flowchart of the conventional example shown in FIG. 3, the following operations will be omitted.

If the operator does not take any action before the tone ringer signal sounds N times in step 5102, step 510
If No in step 2, the process proceeds to step 5107, the hands-free call mode.

After this step 5107, the operator presses the hands-free start button 7 in step 5103, and then steps 5107
, the hands-free mode is entered, a hands-free call is made, and when the hands-free call ends, the process proceeds to step 310B, where the operator presses the hands-free switch 7 with a hands-free end button, thereby ending the step 5106. It becomes a story.

In addition, in step 5102, when the response hold button on the handset 5 is pressed, the response hold mode is entered in step 5109, and the subsequent processing is the same as that in step 5309 and subsequent steps in the flowchart of FIG. Avoid duplicate explanations.

In addition, when the car telephone system of the present invention is installed in a car with a driver, by using the hands-free phone for the rear seat as the handset for the driver, the person in the rear seat can hear the tone ringer signal N times. The driver can make a call by lifting the handset or, if the driver is the only one, by ringing the tone ringer signal N times. Such usage is also possible with the present invention.

〔Effect of the invention〕

As described above, according to the present invention, when a call is received, if the operator does not perform any operation even after the tone ringer signal rings N times, the driver automatically enters the hands-free call mode. It is now possible to talk on the phone without making any dangerous movements while driving.
