Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telephone such as a mobile communication terminal, and more particularly to an answering machine function.
[0002]
[Prior art]
The answering machine function of a mobile communication terminal or the like is generally based on an answering machine center or a method in which the terminal itself has an answering machine function and stores voice data inside the terminal. The former is connected when the user is out of service area. The latter is often used when the user is temporarily unable to answer the phone for reasons such as in the train or during a meeting.
[0003]
In the answering machine function, an answering machine is set in advance, or a voice message is sent to the other party by operating when there is an incoming call. When recording, the answering machine is generally recorded for a predetermined number of seconds. In other words, the other party who made the call can only communicate his / her will only by voice, and the information is not transmitted in real time.
[0004]
[Problems to be solved by the invention]
In the prior art, when this function is actually used, many people hang up without putting a message. This is probably due to the embarrassment of speaking to something that is not responding as the other party's psychology when it is determined that the other party is not a big errand and there is no need to record. On the other hand, in case of an emergency, you may want to have a response during the meeting, but the user may not be able to hear the message until the meeting is over, and contact will be delayed, which is very inconvenient. It was.
[0005]
The present invention has been made in view of the above points, and an object of the present invention is to provide a telephone having an answering function that is very convenient to use.
[0006]
[Means for Solving the Problems]
The telephone of the present invention has a first means for sending a response message to the other party when the incoming call is set and an answering machine function is set, and from the other party in response to the response message. When information corresponding to the desired coping method is obtained, a second means for setting the operation state corresponding to the coping method desired by the other party is provided based on the information, and according to the information from the other party When the operation state for continuing the call is selected and the called party is not on the telephone for a predetermined time, a message notifying the telephone is sent to the other party to finish the call .
[0007]
In the above telephone set, when there is no information corresponding to the coping method desired from the other party for a predetermined time, it is preferable to send a message to the other party and send the message to the other party. Also, each operation state corresponding to each numeric key, the information from the other side to select the operating state can be obtained by DTMF signal of each numeric key. Furthermore, each operation state corresponds to each numeric key, and data can be exchanged between the counterpart terminals as additional information other than a call.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a telephone according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 3 is a block diagram showing a mobile communication terminal as an embodiment of the present invention. In this figure, reference numeral 1 denotes a microcomputer (CPU) that controls the entire terminal. This CPU 1 includes a digital signal processing circuit (DSP) 4, a DTMF encoder / decoder (hereinafter simply referred to as DTMF) 5, a message re-recording circuit 9, A memory 10, a display unit 11, a key input unit 12, a ringer 13, a vibrator 14, and an LED 15 are connected. The memory 10 includes a ROM and a RAM, and stores a program that defines the operation processing procedure of the CPU 1, arithmetic data, input data, reception data, and the like. The key input unit 12 performs input of a telephone number, setting of various operation modes, and the like. The display unit 11 is composed of an LCD and displays various information, the state of the telephone, and the like. The ringer 13 rings when an incoming call is received to notify the user of the incoming call. The vibrator 14 vibrates when an incoming call is received or when the other party is responding or not responding at the time of making a call, thereby notifying the user. The LED 15 blinks when an incoming call is received and visually notifies the user of the incoming call.
[0009]
The DSP 4 digitally processes the RF signal received by the antenna 2 and frequency-converted by the RF circuit 3 to generate a demodulated signal, while the digital signal processing of the input signal generates a transmission signal to generate the RF circuit 3. To the antenna 2. The DTMF 5 receives the output signal of the DSP 4 and decodes the DTMF signal, and the decoding result is sent to the CPU 1. The message re-recording circuit 9 records a response message in advance, and this response message is supplied to the DSP 4 when reproduced. The message re-recording circuit 9 receives the output of the DSP 4 and records a message from the other party. The audio circuit 6 amplifies the audio signal obtained from the DSP 4 via the DTMF 5, supplies it to the speaker 7 and reproduces it as audio, and amplifies the audio signal input from the microphone 8 and supplies it to the DSP 4 via the DTMF 5. To do. Note that the DTMF 5 and the message re-recording circuit 9 can be incorporated into the DSP 4.
[0010]
In the mobile communication terminal as described above, when the answering machine function is set at the time of incoming call, a response message is sent to the other party to make the other party select the desired countermeasure, and the other party responds to the response message. When information corresponding to the desired coping method is obtained, the operation state corresponding to the coping method desired by the other party is set based on the information. The above operation will be described in detail below with reference to the flowchart of FIG. Information from the other party is obtained by a DTMF signal corresponding to each numeric key.
[0011]
If there is an incoming call in step S1 in FIG. 1, it is determined in step S2 whether the answering function is set. If the answering machine function is not set, normal incoming call processing in step S3 is performed. On the other hand, if it is determined in step S2 that the answering machine function is set, the process proceeds to step S4, where the response guidance (response message) is reproduced from the message re-recording circuit 9 and sent to the other party.
[0012]
Here, as the response guidance, as shown in Figure 2, "If you want to call in an emergency, please press 1. If you want a call back, please press 2. If you want to call later, please press 3. If you want to enter a voice message or text message, please press 4. " Therefore, the other party listens to this response guidance, presses the number key that matches the desired countermeasure, and returns the DTMF signal of that number to the called party.
[0013]
Therefore, the incoming side waits for the input of the DTMF signal from the other side after sending the response guidance (step S4), determines whether the DTMF signal is input (step S5), and decodes the DTMF signal (steps S6 to S9). ) Is repeated for the number of retries (n) (step S10). If it is determined that there is no DTMF signal input within the retry count, the process proceeds to step S11 to send a message “please call me back” to the other party, and the call ends in step S12. Even within the retry count time, if there is no DTMF signal input and the set time is exceeded (step S13), a message "Please retry" is sent to the other party (step S14). This is the end of step S15.
[0014]
On the other hand, when the DTMF signal is input from the other party within the retry count time or the set time (step S5), the DTMF signal is decoded by DTMF5 (steps S6 to S9), and according to the result. It becomes the operating state. If the decoding result is the number 1 as shown in step S6 (the other party wants to call it as it is urgently), a message “Please call me” is displayed on the display unit 11 (step S16). ) Further, the ringer 13, vibrator 14, and LED 15 are brought into a calling state again (step S17). Note that this operation can be changed by a prior setting. For example, during the manner mode, the ringer 13 does not ring. And if a user responds to such a call, it will be an incoming call of Step S19. On the other hand, in spite of such a call, if the user rejects the incoming call by pressing the key or times out (step S18), a message is sent to the other party saying “cannot be reached” (step S20). ), The end of step S21. Here, instead of “I can't get out”, you can send a “Please call me again” message to the other party, and these messages will be sent to the other party either automatically or by a predetermined key press. The
[0015]
If the decoding result of the DTMF signal is the number 2 as shown in step S7 (the other party wants a call back), a message “Please call me” is displayed on the display unit 11 (step S22). This is the end of step S23.
[0016]
When the decoding result of the DTMF signal is the number 3 as shown in step S8 (the other party wishes to call again), a message “Call me” is displayed on the display unit 11 (step S24). This is the end of step S25.
[0017]
When the decoding result of the DTMF signal is the number 4 as shown in step S9 (the other party wishes to record a message or send a message), the display unit 11 displays “Recording” or “Message At the same time, the message from the other party is recorded in the message re-recording circuit 9, or the message from the other party is stored in the memory 10 (step S27). .
[0018]
As described above, according to the above-described mobile communication terminal, “display a message indicating that a return call is desired” corresponding to the numeric keys “2” and “3” is displayed on the display unit. By selecting the “activate” operation state, the other party who made the call can communicate the will to the other party without leaving a message. In addition, if the “continue calling” operation state corresponding to the numeric key “1” is selected, the will can be communicated even in the event of an emergency that the user wants to call. Furthermore, the side that receives the call can take actions such as making a call again based on the situation (conference, driving, etc.) and the information transmitted by the other party, and the answering machine function can be effectively utilized. That is, according to the mobile communication terminal, it is possible to obtain an answering function that is very convenient to use.
[0019]
In the above embodiment, information corresponding to the desired countermeasure on the other side is received by the DTMF signal and the DTMF signal is decoded inside the terminal. However, the DTMF signal may be decoded in the base station. In that case, the information is transmitted to the terminal as data other than a call. In the case of mobile communication terminals, information may be transmitted by exchanging data without using a DTMF signal. Furthermore, although the above embodiment is a case where the present invention is used for a mobile communication terminal, the answering function of the present invention can of course be applied to a home fixed telephone.
[0020]
