Abstract

PURPOSE:To perform the evaluation of priority by storing previously the message which is automatically sent to an originating subscriber in automatic reply to a call waiting mode, using another channel to send voices to the call waiting original subscriber and also receiving the message from the originating subscriber for the display of characters. CONSTITUTION:When a call is received from a third party via an information channel B1 in a busy mode, a signal decoding/generating part 20 detects said incoming call via a signal channel D and sends a call waiting display tone to a telephone circuit 30. Thus a speaker depresses a call waiting answer 34 after receiving the display tone and a signal decoding/generating part 40 detects the depressing of the switch 34 and transmits an answer signal to an exchange via the channel D. The exchange put the call waiting voices of the third party on an information channel B2 to send them to the circuit 30. While the channel B2 is connected to a voice synthesizing/recognizing part 32 via a switch part 23. The part 32 sends the message to the third party and the received voices are recognized to be converted into the character information. This character information is displayed at a display part 33.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a call waiting display telephone that transmits and receives voice data by time division multiplexing in digital codes.

[Conventional technology]

Conventional digital telephones have display means for displaying caller information, such as a telephone number, included in data received by the digital telephone as incoming call information.

Referring to No. 51, the receiving path 11 of the digital line 10
The digital telephone connected to the artificial transmission path 12 has a code receiving means 21. Code sending 1g means 22° telephone circuit 30. Information detection means 41. The code receiving means 21 divides the digital code received from the receiving path 11 into voice and data, and transmits the voice to the receiving path of the telephone circuit 30. All data is sent to the information detection means 41. The code transmitting means 22 receives all the digital codes of the voice output from the transmission path of the telephone circuit 30, receives the data to be transmitted in seven digital codes, arranges them in series at respective time positions, and transmits them to the connected destination.
12't-. The telephone circuit 30 converts the digitized voice code received through the receiving path and the sending path into analog form and connects it to a handset (not shown). The code receiving means 2 is connected to the information detecting means 41 from the receiving path 11.
Analyzes all friend data received via 1' and detects all information. The data transmitted during the call takes into consideration the efficiency of line usage, and usually includes the minimum required ring signal, calling party number,
For example, "Caller number 234-5678".

The information display means 90 receives information from the information detection means 41 and displays, for example, "Calling from telephone number 234-5678" in text. Since it is difficult to explain the present invention, the calling function block of the digital telephone is not shown in FIG. 5, and the explanation thereof will be omitted.

Mayo, referring to FIG. 6, in other conventional telephones 60, the telephone circuit 6, the switch section 64, the information channel 62, and the 63-[No. assembly and division 61-line]〇-communication network ( [not shown] - L92a to the path of the filling machine (not shown)

is connected to. Here, if there is a new incoming call from a third party, the incoming call display information will be displayed on the signal channel 67.
All signals are transmitted from the communication network to the signal decoding/generating section 68 of the telephone 60. The signal decoding/generating section 68 decodes all of the incoming call display information, generates an incoming call indicating sound, and sends it to the telephone circuit 66 to display an incoming call to the caller. Upon receiving this display, the caller decides whether to answer or not to respond to the N call being displayed by the third party (rLfc), and presses the incoming call response switch 69 when answering. The signal decoding/raw 11iliC@68 sends an F response signal to the signal channel 6 when the response switch 69 is pressed.
7 to the communication network. The communication network takes advantage of the receipt of this response signal and changes the content of the information channel 62 from that of the original caller to that of the third party who received the call during the call.

Note that the data communication circuit 65 is connected to the switch g64. The information channel 62 or 63 is used for all data communications.

[Problem that the invention seeks to solve]

7 mentioned above? The call waiting display of the digital telephone shown in Fig. 5 is configured to display the information of the data that the telephone has just received from the exchange equipment in characters, so the caller's message of the call waiting is usually displayed. Only the telephone number is displayed in text, and the caller's intention to call is not displayed. Further, the telephone set shown in FIG. 6 only displays all incoming calls to the caller with a specific sound. For example, it is impossible to judge the priority of the called party from the caller's level of urgency regarding the general call, so it is impossible to judge the priority of the called party from the caller's level of urgency. There is a problem in that the first call must be temporarily interrupted and answered.

[Friendly means of solving problems]

The incoming call display telephone set of the present invention comprises: information detection means for detecting incoming call information transmitted from a line; storage means for storing in advance a response message sent to the caller of the incoming call; response means for responding to the telephone line and storing the response message in the storage means according to the detection result of the detection means; and response means for reading out the response message and sending it to the caller; Embodiment The present invention will now be described with reference to the drawings.

For example, the channel 81 is composed of a demultiplexer, and the channel 81 is 64Kb.
The channel B2 also has a code rate of 64 Kbps to the receiving path of the telephone circuit 30 having a code rate of 64 Kbps, and the channel Df1 to the injury message recording means 51.
For example, at a code rate of 16 Kb, the information detecting means 4
1, that's how you connect. The code receiving means 22 receives digital codes from a channel B1 connected to the transmission line of the telephone circuit 30 and a channel B2 connected to the automatic answering means 43. , a frame is formed and transmitted according to a predetermined transmission procedure to the transmission path 12 shown in FIG. 2(a). The transmitting means 22 includes a handset (not shown) for communicating by receiving and communicating with a telephone line and a digital code. The information detecting means receives and analyzes the data information of the channel D, and detects, for example, a "busy N bias" signal and "calling party number" information. The signal display means 42 receives an instruction A according to the detection information of the information detection means 41-G→i→4→→.
fc decoding t, for example, when a signal of "calling in progress" is detected, a display lamp (not shown) indicating "call in progress" is lit and displayed. 41, and sends all response signals to the code transmitting means 22 via the channel Dt-, and then retrieves the message from the response message storage means 44 and transmits it to the channel B2. '! - The response message storage means 44 stores in advance a message to be sent to the caller at the time of automatic response. This automatic response message may be, for example, ``I am currently on the line and have a message for you. I will relay it to you immediately, so please speak to me.'' The injury message recording means 51 receives and records all messages from the caller, who is the connection destination during the call, via the channel B2'.

The display instructing means 52 detects all button operations by the caller, for example, and instructs the display driving means 53 to display all messages. When the display drive means 53 receives an instruction to display a message from the display instruction means 52, the information detection means 41 detects incoming call information during a call and transfers the received friend information to the message display means 54. Incoming call/person in heat 234-5678J 7 characters will be displayed. Subsequently, this display driving means 53 extracts the message received by the friend recorded by the received message recording means 51, transfers it to the message display means 54, and displays it in characters.

In the above embodiment, regarding the function of the telephone to make a call, a switching means (not shown) is installed according to the state such as call, N call, FI call, etc. in the common function block omitted in the block diagram and explanation. It's a lie to switch. The information detection means 4
The illustrations and explanations of functions and service information other than the present invention detected by 1 have been omitted.

Next, with reference to FIG. 1 and all of FIG. 2, the main operating procedures for an incoming call will be explained. First, when a call is received on channel B1 while a call is in progress (operation procedure 1), an exchange (not shown) determines that the call is in progress and connects the incoming call to channel B2. A signal indicating "call waiting" is sent to channel D. The information detection means 41 of the telephone receives the signal information of the channel D from the injury path 11 through the code reception means 21t (operation procedure 2), and detects a signal indicating a busy group (operation procedure 3). ).This "incoming call" is displayed to the caller 1g, and at the same time, the calling party's number is displayed on the display means 54 (operation step 4).

When the automatic response means 43 is activated, this automatic response means 4
3 transmits an F response signal to the code transmitting means 22 on the channel D of the transmission path 12 (operation procedure 5). At the same time as sending a response signal to the automatic response means 43, the automatic response message is retrieved from the response message memory #R, 44, and the exchange (not shown) stops the Omotesui No. 1B during the call to the caller and connects the call path. Wait for a predetermined time to connect the
An automatic response message is sent to channel B2 in the form of digitized voice (operation step 6). After hearing this response message, the message voice spoken by the caller is sent to the exchange (not shown) and transmitted on the channel B2, so it is sent to the message recorder 51 via the code receiver 1N means 21. Received message record (operation procedure 7) When the display instruction means 52 instructs the message to be displayed in characters (operation procedure 8), the display driving means 53 retrieves the message from the received message storage means 51. Then, the message display means 54 displays characters (operation step 9), and the operation ends. In the above embodiment, it was explained that the telephone receives a signal indicating "call waiting" from the exchange (not shown), but the telephone detects "call waiting" when the telephone receives a ringing signal during the call. It's hard to do anything. In the above embodiment, a telephone is described as an FI communication terminal. Therefore, the received message storage means 51 has a voice recognition function that selects a digitized voice code to the message display means 54 and converts it into a ratio display character code. The recorded message may also be broadcast from a speaker (not shown) if an audible instruction is included instead of a visible display instruction.

In the case of a combination with a data terminal, when transmitting the terminal type of the user along with the caller number, the digital code of character data is transmitted on the channel B2. It is also possible to directly drive the received code to display characters.

In the above embodiment, the digital code transmitted to the connection line of the telephone is divided into three channels B1, B2, and D.
Each code transmission speed I! ? 64Kbps, 64
Although the explanation is that the Kbps is 16 Kbps, the channel division and code transmission rate are not limited to the above explanation. My friend also explained that the display means displays text.
This character is 1, for example, a symbol that can be displayed by operating a button on a keypad.
