Description

CALL WAITING ANNOUNCEMENT METHOD IN AN AUTOMATIC RESPONSE TELEPHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call waiting function of an answering machine, and more particularly, to a call waiting method capable of switching from a call waiting state to an answering mode at the request of a calling party.

The call waiting function refers to a function of having a telephone answer first when there is an incoming ring and waiting for a caller for a predetermined time until the user answers the call.

Referring to the standby call guide function provided in the conventional answering machine, when a ring corresponding to the incoming call is received, a call loop is immediately formed and an out going message (OCM) is transmitted through the formed call loop. For example, the message “Please wait” for the sent out OGM was sent out every 5 seconds for 30 seconds. In addition, the tone continues to sound so that the user can respond while the OGM is being sent. In response to the ringing tone, if the user's call request is detected within a predetermined time of 30 seconds, the OGM and the ringing tone are blocked and the call according to the incoming call is connected. The call request of the user refers to a hook-off of a handset, an input of a speakerphone call key, and the like, and in the case of a wireless telephone, includes a call key input of a portable device and a departure from a charger. If the call request is not detected until the predetermined time 30 seconds elapses, the auto answer mode is performed. The automatic response mode refers to a mode of recording a received message received from the other party after transmitting the voice announcement message.

As described above, the call waiting guide function, which has been performed in a conventional answering machine, repeatedly sends a guide message for a predetermined time, which causes a problem that the caller does not leave a message to be delivered midway and hangs up the call.

Accordingly, an object of the present invention is to provide a method for performing an auto answer mode by a request of a calling party which is received within a call waiting time.

1 is a block diagram of an answering machine according to an embodiment of the present invention.

2 is a control flowchart for call waiting guidance according to an embodiment of the present invention.

Hereinafter, a configuration according to an embodiment of the present invention will be described with reference to the drawings.

The configuration of the answering machine according to an embodiment of the present invention is as shown in FIG.

Referring to FIG. 1, the controller 10 controls the overall operation of the phone according to a control program stored in the memory 28. The call circuit unit 14 controls various tone signals, ring signals, and call voice signals under the control of the controller 10. Hook relay (H / S) is mechanically operated by the lifting of the handset to form or block the communication path between the call circuit unit 14 and the telephone line. The call relay 12 forms or blocks a call path between the call circuit unit 14 and the phone line under the control of the controller 10. The handset 16 includes a handset for converting a voice signal generated from a subscriber into an electrical signal and a handset for converting an electrical signal into a voice signal to generate an audible sound. The DTMF generating unit 18 converts the data provided from the control unit 10 into a DTMF signal and transmits the DTMF signal to the call path unit 14. The tone detection unit 20 converts a tone signal such as a DTMF signal corresponding to the telephone number of the transmission side received through the call circuit unit 14 into predetermined data and provides it to the control unit 10. The ring detection unit 22 is connected to a telephone line that enters the hook relay H / S, detects a ring signal received through the telephone line, and provides the ring signal to the controller 10. The display unit 24 displays the current operating state of the phone under the control of the control unit 10. The key input section 26 generates key commands and key data according to the keys pressed by the user to control the operation of the telephone. The memory 28 stores data according to the operation of the control program and the telephone. The data includes data corresponding to the received telephone number. The timer 30 is provided inside the control unit 10, and counts a predetermined clock to check an operation time based on a current time and a function setting. The answering machine 32 includes a voice processing unit 36, a codec 34, and a voice memory unit 38 to reproduce an out going message (OCM) or to record an in coming message (ICM). The voice processor 36 processes a digital signal for binary encoding a digital signal input and output to the codec 34. The voice processor 36 has a RAM for storing numeric data provided from the controller 10 therein. The voice memory unit 38 stores data provided by digital signal processing from the voice processor 36.

The control process for call waiting guidance according to an embodiment of the present invention is shown in FIG. 2.

In the control process of FIG. 2, a call loop is formed in response to a ring call, and then the announcement message is transmitted at a predetermined interval through the formed call loop, and a request for switching from the calling party to the auto answer mode while the announcement is sent. When the received or a predetermined time has elapsed, the automatic response mode is performed, and if there is a call request while the guide message is sent, the transmission of the guide message is blocked and the call mode is performed.

Hereinafter, an operation according to an embodiment of the present invention will be described in detail with reference to the above-described configuration.

The controller 10 detects the incoming ring in step 210 with the call waiting guide function set. If the incoming ring is detected while the call waiting guide function is set, the controller 10 proceeds to step 212. If the control unit 10 proceeds to step 212 to control the call relay 12 to connect the telephone line to the call path unit 14 to form a call loop. When the call loop is formed, the controller 10 controls the answering machine 32 in step 214 to send an OGM through the call loop at predetermined intervals. For example, the OGM says, "I am on my way to answer a call. If there is an emergency, please tell me who is it?" The method for recording the OGM for guiding the call waiting is performed by the same process as the method for recording the OGM in a telephone equipped with an answering machine. For example, OGM, which guides the call waiting, says, "Do not hang up. Please wait. I am on the way to answer the call. If you have any questions, please press the # button and speak." The OGM in the above example is reproduced and sent out at a predetermined period (about 5 second intervals) for a predetermined time (about 30 seconds). The control unit 10 continues to generate a ringing tone in response to the incoming call while the OGM is transmitted.

The control unit 10 detects whether the tone signal for the "#" button for requesting the switch to the auto-answer mode is input through the tone detection unit 20 in step 216, and checks the internal timer 30 in step 218. Detects whether a predetermined time (about 30 seconds) has elapsed after the call loop is formed. In addition, if the predetermined time has not elapsed in step 218, the flow proceeds to step 226 to detect whether there is a call request. The call request of the user refers to a hook-off of a handset, an input of a speakerphone call key, and the like, and in the case of a wireless telephone, includes a call key input of a portable device and a departure from a charger. If the call request is detected in step 226, the controller 10 proceeds to step 228 to perform a normal call mode.

If the input of the "#" button is detected in step 216 or the elapse of a predetermined time in step 218, the controller 10 blocks the call sound and proceeds to step 220. When the controller 10 proceeds to step 220, it performs the automatic response mode. The automatic response mode is performed by sending an OGM indicating that the automatic response mode has been switched and recording an ICM received in response to the OGM. In addition, the ICM received in response to the OGM is output through an external speaker (not shown) provided in the telephone. While the auto answer mode is performed, the controller 10 detects whether there is a call request in step 222, and detects whether there is a termination request in step 224. The call request of the user refers to a hook-off of a handset, an input of a speakerphone call key, and the like, and in the case of a wireless telephone, includes a call key input of a portable device and a departure from a charger. In addition, the termination request includes the detection of the busy tone provided from the local exchange (not shown) through the tone detector 20 and the input of the call blocking button when the call is blocked by the calling party subscriber. If the call request is detected in step 222, the controller 10 proceeds to step 228 to perform a normal call mode. Otherwise, if the end request is detected in step 224, the controller 10 ends the function according to the present invention.

The present invention solves the problem of having a caller wait for a caller because the caller can record a voice message without waiting for a predetermined time in the answering machine.
