[Detailed Description of the Invention] <Industrial Application> The present invention relates to an emergency call method in a car telephone system, and in particular to a car phone that can promptly notify a predetermined contact of the occurrence of an emergency situation. Regarding the emergency call method in the system.

<Prior art> There has been an increasing demand for the generalization of car phone systems due to the expansion of motor vehicles, business, security, etc., and a car phone system called a cellular one-way system has been developed and has become extremely popular, especially in the United States. is showing. This cellular system subdivides the service area into multiple cells with a radius of approximately 6.4 km, and each cell has one wireless telephone station (
This is a method of communicating with the other party by installing a base station (base station) and changing the base that receives radio waves from the telephone in the car one after another as the car moves.It allows calls over a wide range, increases the number of channels, and has an unlimited number of lines. can be increased to

In such a cellular one-way car phone system,
By turning on the ignition switch and turning on the power switch, the user can answer a call from the other party and make a call to the outside from the car telephone system.

<Problems to be solved by the invention> By the way, in the conventional car phone system, even if an emergency situation occurs, the caller must follow the normal calling steps to call the other party, so it is not possible to quickly notify the other party of the emergency situation. . In particular, in cases of high urgency, such as the appearance of a taxi robber or the appearance of an assailant while parking, the conventional method does not have enough time to call the other party.

From the foregoing, it is an object of the present invention to provide an emergency call method for a car telephone system that is easy to operate and can quickly notify a desired contact of the occurrence of an emergency situation.

Means for Solving the Problems> FIG. 1 is a block diagram of a car telephone system that implements the emergency call method according to the present invention.

, a transmitting section 102b, a switching section 102C that appropriately connects the antenna 104 to the receiving section and the transmitting section, a synthesizer 102d that generates a predetermined frequency signal, a control section 102e, and an emergency sound generation device 102f. . The emergency sound generator 102f is a tone generator that outputs a sound with a predetermined tone or a predetermined emergency message (text).
It consists of a voice response device that outputs.

The emergency call switch 103 is placed, for example, at the feet, but the position is not limited to the feet, but may be placed anywhere.

Control unit 101 and transceiver unit 1
02 are interconnected by multiple power control lines, multiple digital data transmission/reception lines, audio lines, etc.

The emergency call method according to the present invention will be explained below according to the flowchart shown in FIG.

When an emergency situation occurs, the telephone number of a contact person to be notified of the emergency situation is stored in advance, for example, in the memory MEM built in the control section 102e of the transceiver unit 102.

Incidentally, the operation of storing the telephone number in the memory MEM is performed, for example, as follows.

That is, after inputting a telephone number by pressing the numeric key of the numeric key part 101d-1 of the hand cell 1-HDS (see FIG. 3), the store key STO of the function key part 101d-2 is pressed. As a result, the control section 101a sends the telephone number to the transceiver unit 102 via the digital data transmission/reception line, and the control section 102e of the transceiver unit 102 memorizes the telephone number.
Store in EM. Incidentally, although only one telephone number may be stored, in the following it is assumed that several telephone numbers are stored in the memo IJMEM in the same order of priority.

(1) Control unit 1 configuring transceiver unit 102
The processor 02e constantly checks whether the emergency call switch 103 is turned on.

(2) If the emergency call switch 103 is not turned on, the control unit 102e performs another process.

(3) When an emergency situation occurs and the driver operates (turns on) the emergency call switch 103, the control unit 1028 internally turns the ignition on and the power on.

In other words, if the ignition switch is off, it is in the same state as on, and the power on/off switch PW (
(Fig. 2) is off, the power is turned on.

(4) Next, the control unit 102e changes 1→i.

(5) After the transfer, the control unit 102e stores the first data in the memory MEM.
Check whether the rank phone number is registered.

(6) If the i-th telephone number is registered, the control unit 102e makes a call in the same way as if the telephone number had been dialed in a normal operation, and starts timing. Note that the telephone number (digital data) is output to the transmitting section 102b, where it is modulated with the frequency signal input from the synthesizer 102d, and then power amplified, and then sent to the switching section 102C.
The signal is transmitted from the antenna 104 to the base station to which it currently belongs.

(7) From now on l-lanceiver unit I-102 no lJt&
11102e checks whether the called party has taken off the receiver. Note that whether or not the handset has been disconnected can be detected by monitoring the call progress tone.

(8) If the other party does not take off the receiver, time counting is continued, and it is checked whether the time t has exceeded a predetermined time T, and if the caller does not pick up the phone, the call is continued.

(9) If the other party hangs up the phone before the call is over, the control unit 102e detects this and sets the phone to a hook-off state, making it possible to send a message from the emergency voice generating bag W102f.

(1φThen, the emergency voice generating device 102f is driven to input an emergency message to the transmitter 102b.

It should be noted that the emergency message may be a special tone that indicates an emergency, or may be a pre-stored text that indicates the occurrence of an emergency (for example, ``emergency has occurred'').

Note that the emergency message is modulated and amplified by the transmitter 102b and then transmitted from the antenna 104.

(It) In parallel with sending the emergency message, the control unit 102
e checks whether the other party has hung up the receiver.

(If the handset is not put down, it is checked whether the predetermined time T2 has elapsed, and if it has not elapsed, the emergency message continues to be sent.

(If the handset is hung up in step 1 (Ill) or a time-out (t>72) occurs in step 17G, the control unit 102 sets el to the hook-on state.

(14) After that, if the ignition switch is off, the ignition is turned off, and if the power on/off switch is off, the power is turned off. The above results in the initial state.

(15) On the other hand, if the time is over (t>T,) before the other party takes off the receiver in step (8), the control unit 1
02e changes from 1+1 to 1 and repeats the process from step (5) onwards. Incidentally, if the telephone number of the first order is not registered in the memory MEM in step (5), the processing from step (+31) is performed.

In addition, in the above example, the phone numbers of multiple contacts are registered in order of priority, and if the high-priority contact is away, etc., the lower-priority contacts are called in turn, but only one phone number is registered. It can also be configured to keep

<Effects of the Invention> According to the present invention, an emergency call switch is provided in a car telephone system, and the telephone number of the party to whom a predetermined message is to be sent when the emergency call switch is operated is stored in advance in a memory. When the emergency call switch is operated, a call is made to the telephone number stored in the memory as the destination and the contact is notified of the occurrence of an emergency situation, so the operation is simple and quick. Contacts can be notified of the occurrence of an emergency.

Further, according to the present invention, the telephone numbers of a plurality of contacts are stored in the memory in advance with priorities set, and when the first priority contact is not connected even after making a call for a predetermined period of time, the next priority contact is sent. I configured it to call first, so I can be notified of an emergency with a high probability.
