Description

Cordless Phone with Auto Answer

The present invention relates to a wireless telephone equipped with an automatic answering function. In particular, when the wireless handset detects a call separation distance and determines that the wireless handset is in a position beyond the available calling distance, the wireless answering device performs an automatic answering function. The present invention relates to a wireless telephone having an auto answering function capable of transmitting stored data during an auto answering function by dialing a pager's call number.

Telephone terminals, which are widely used throughout the company and our living spaces as well as homes, are the most basic daily necessities of modern people who have reached the information age. The wireless telephone is commercialized and widely spread by allowing the user to make a call even at a distance away from the main body of the telephone by wirelessizing the main body.

The wireless telephone is composed of a telephone line, i.e., a main body electrically coupled to a trunk line, and a wireless handset that provides a call function to a user by transmitting and receiving a predetermined frequency signal (RF signal) to the main body. The body also has an automatic answering device for storing the sender's message when the subscriber is away.

In the wireless telephone, when the subscriber presses the automatic answering function button when going out, when the user goes out, the message and the telephone number data of the sender are stored by performing the automatic answering function when a ring signal is detected a predetermined number of times, and the subscriber returns home. When a contracted operation such as pressing a message confirmation function key is performed, the stored data can be confirmed by voice.

However, since the main body and the handset transmit and receive voice data and the like through a predetermined frequency signal, the range in which the radio handset can be used is limited to a predetermined distance with respect to the main body.

In recent years, wireless telephones have been developed and widely distributed by using a high frequency, such as 900 MHz, as a transmission / reception frequency between the main body and the wireless handset. Of course, even if the user is within a certain distance, even if the transmission and reception frequency is disturbed by the building, etc., the user cannot make a call through the wireless handset.

Therefore, in using the radiotelephone, a user may not receive a call in an urgent situation in which the sender is trying to convey important information struggling with the town.

Accordingly, the present invention has been made in view of the above circumstances, and when the wireless handset is in a call-disabled state, the main body recognizes it and performs an automatic answering function, and also dials the page number of the pager held by the subscriber. The purpose of the present invention is to provide a wireless telephone with an automatic answering function that can transmit the stored data during the automatic answering function.

A microcontroller that performs a function, 31, is a DTMF generator that outputs a DTMF signal corresponding to the number data applied from the microcontroller 30. FIG.

Next, the operation of the radiotelephone having the above-described configuration will be described with reference to the operation flowchart shown in Figs. 2A and 2B.

First, in a normal standby state where the subscriber does not use the wireless handset, the control unit 9 controls the RF transmitter / receiver 7 so that the RF transmitter stops driving and the RF receiver periodically drives on / off (ST1).

Subsequently, when a predetermined control signal such as a ring signal is received from the main body in the standby operation state (ST2), the microprocessor 9 controls the ACK signal generator 8 to control the ACK signal through the RF transmitter / receiver 7. In addition to transmitting the to the main body and outputs the ring signal received through the speaker 3 (ST3).

When the subscriber wants to talk to the wireless handset and presses the ON button by operating the keypad 1 of the wireless handset, the control unit 11 drives the RF transmitter / receiver 7 in a normal state, By outputting a predetermined control signal for the handset, the handset is set in a state where a call is possible.

The operation of the wireless handset is substantially the same as that of a conventional wireless handset.

On the other hand, in the main body, the microcontroller 30 outputs a ring signal to the wireless handset through the RF transmitter / receiver 22 when the ring detection signal is input from the ring detector 12 in the standby state (ST11) ( ST12).

When an ACK signal is received from the wireless handset for the RF signal transmission (ST14), normal control processing is performed (ST17). That is, when the user operates the on-hook button provided on the keypad 1 of the wireless handset with respect to the above-mentioned ring beep, the corresponding RF signal is inputted through the RF transceiver 22 of the main body. In addition to turning on, the voice controller 20 is coupled to the RF transceiver 22 so that the user can make a call with an external caller through the wireless handset.

On the other hand, if the ACK signal is not received from the wireless handset until a predetermined time has elapsed in step ST14 (ST14, ST15), the DSP 25 is controlled to execute the auto answer function (ST16). That is, at this time, the DSP 25 reads the guide message stored in the guide message storage unit 26 and outputs the guide message to the trunk line through the network circuit unit 19. Accordingly, the caller of the other party can call " Please enter the phone number where you will be contacted. You will hear a prompt like:

Subsequently, when the other party's caller inputs his or her number according to the above guide message, the DTMF signal corresponding to the input number is input. The microcontroller 30 inputs the number data from the DTMF detector 29. In step S18, the input number data is stored in the memory 15 (ST19).

Next, when the other party's caller is on-hook (ST20), the trunk line connection unit 18 is off-hook, i.e., turned off, and then it is detected whether or not a call number is registered in the call number storage unit 28 (ST21). At this time, if the call number is registered, the trunk line connection unit 18 is turned on again, and the number data stored in the call number storage unit 28 and the memory 15 is sequentially processed through the DTMF generation unit 31. By outputting the result, the predetermined call processing is executed (ST22). Of course, in executing the above call processing, after the call number is output, data corresponding to the number " 1 ", for example, is output to the DTMF generator 31 after a predetermined time delay.

In addition, in step ST18, the caller terminates the call without inputting a desired call number, or if the call number is not registered in the call number storage unit 28 in step ST21, call processing is not executed. .

In addition, in the registration of the call number for the call number storage unit 28, after the user operates a predetermined function key of the keypad 16, the user inputs his / her call number using the number keys, and then returns the function key. The operation is simple.

That is, according to the above embodiment, when the subscriber is away from the available distance with the wireless handset, the main body detects the distance of the wireless handset to perform the auto answering function, and calls the stored call number to guide the number of the call requester. Will be given.

Therefore, the user can use the wireless telephone in a stable state.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, even when the wireless handset is out of the callable distance, the main body detects this and automatically performs an automatic answering function. It can be realized.
