Abstract

PURPOSE:To provide the busy and non-reply state help service system not requiring its service function to a public network by receiving one of services of automatic redial, talking reservation and message recording/delivery without knowing the service content in advance even when a tele-point caller encounters a busy state or a non-reply caller and not requiring the service function for a called party terminal equipment. CONSTITUTION:A slave set 2 at a tele-point makes a call to a telephone set terminal 7 accommodated in a public network. When the telephone terminal 7 is busy or does not reply a call, the public network 6 detects automatically the busy state or the non-reply. Then the network 6 sends it to a caller in terms of a message that one of plural services is received and the caller selects one of them by a dial number. Thus, one of the automatic redial, talking reservation and message recording/delivery is received.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention enables a telepoint caller to receive help services such as automatic redialing, call reservation, and message recording/transmission over the public network when the caller encounters the dialed party is busy or absent. Regarding the method.

0002

2. Description of the Related Art Various services are provided in telephone exchange networks for the convenience of users. Conventionally, the following services existed when the destination was busy or absent.

[0003] If an incoming call is received while the call is busy, the caller is notified of this by a predetermined signal, and when the caller recognizes this, the caller is temporarily put on standby by a single on-hook operation, etc. A service that allows you to talk to callers (called call waiting).

[0004]Voice mail service A call back to the voice mail device, a message is registered, a message is displayed on the called party's phone to notify that there is a voice mail, and the called party accesses the voice mail device. You can retrieve the message using Deliver the message (convey the message by calling the person to whom you want to convey the message).

[0005] ■Answering machine function The message content of the caller who called while the caller was absent is recorded, and the called party can listen to the recorded content.

[0006] Redial function If the dialed party is busy, the call is automatically repeated until the other party answers.

[0007]

[Problems to be Solved by the Invention] However, each of the above services has the following problems.

[0008] For the service (2), the recipient must subscribe to the service, and messages cannot be transmitted when the recipient is absent.

[0009] For the service (2), the recipient must be using a voice mail service, and it is necessary to know the recipient's personal identification number in advance. Additionally, the caller must call back to the voicemail device and can only leave a message, which is useless if the callee is busy and there is an emergency.

[0010] The answering machine function (■) is that the called party's phone has an answering machine function, and it is not possible to leave a message unless it is set to answering machine, and it is also possible to leave a message even when the called party is busy. I can't.

[0011] With the redial function (■), messages cannot be transmitted when the other party is absent, and it is not a function that can be used from anywhere.

A common feature of the conventional busy or absent service systems described above is that the called party must register such a service in advance. In the case of ■, the calling party needed to have such a function.

The purpose of the present invention is to solve all of the above-mentioned problems, and even if the caller of the telepoint does not know what kind of services are available, he or she can easily receive the service when the caller is busy or absent. The purpose of the present invention is to provide an absentee help service system in a public network where the service can be used and neither the calling side nor the called side need to have a function for this purpose.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in more detail below with reference to the drawings. FIG. 1 is a schematic diagram illustrating a telepoint system using the busy-absence help service method according to the present invention.

[0016] Individual base units 1-1 to 1 in the home or building
-n is installed, and slave devices 2-1 to 2-n are installed corresponding to each individual parent device 1-1 to 1-n. Each slave unit has an ID, which allows it to make wireless calls with the base unit. When there is an incoming call from the line, the handset rings via the individual base unit.

In addition, a large number of public base stations 3-1 to 3-n are installed at appropriate intervals to cover the entire city.
These public base units do not have their own slave units. for example,
When the handset 2-1 moves and enters the service area of the public base unit 3-1, the handset 2-1 can connect to the line via the public base unit 3-1. The public master units 3-1 to 3-n are connected to a data transmitting/receiving unit 4 of the center via a data bus 5, and necessary data is exchanged. When the slave unit enters the service area of the public base unit, it registers its location with the center via the public base unit. When calling this handset, first call the individual base unit of the handset, if the handset is not present, then check whether the location has been registered at the telepoint center,
If the location is registered, use the public base unit where the location is registered. In addition, as a method of calling handsets within the service area of a public base unit, the location registration is not performed and the individual base units of the handsets are called.If the handset is not present, all the public base units are called at once. You can also do it.

FIG. 2 is a block diagram showing an embodiment of a public network to which the system of the present invention is applied. This embodiment shows an example in which a telepoint handset makes a call to a normal telephone terminal. The exchange 8 of the public network 6 is equipped with message recording, automatic busy detection, automatic absence detection, automatic busy termination detection, redial, voice recognition, DTMF signal detection, and dial storage functions in addition to normal exchange connection functions. .

FIG. 3 is a block diagram showing the functions of the exchanges constituting the public network of FIG. 2. This figure shows only the parts directly related to the present invention.

Various terminals, including a telepoint consisting of a handset 20 and a base unit 3, and a telephone terminal 7 are connected to a switch 31 via subscriber circuits 16 and 17. Switch 31 is connected to other exchanges via trunk 21. The control unit 18 not only performs exchange control but also controls each circuit unit for realizing the help service according to the present invention. The voice storage section 22 is a circuit section that stores the specific voice of the caller that is input after a special number is pressed from the terminal during a call or a call. The register 23 is a circuit section that temporarily stores key inputs from the terminal. The voice stored in the voice storage section 22 is recognized by the voice recognition section 30, the key information temporarily stored in the register 23 is decoded by the decoder 29, and the recognition and decoding results are sent to the control section 18.

The key information sent from the telepoint to the exchange is a DTMF signal. The recognition means is the above-mentioned voice storage section 2.
2, a circuit portion constituted by the voice recognition section 30, register 23, decoder 29, etc. corresponds to the circuit section. The RG generator 24 is a circuit that sends out a ringer, and is connected to a destination via a switch 31. The BT generator 25 is a circuit that sends out a busy tone, and is connected to the caller when the caller is busy. The RBT generator 26 is a circuit that sends out a ringback tone, and is connected to a caller when a ringer is being sent to the caller. The timer 28 is a circuit that measures the time during which the ringer is being sent out.

Busy detection depends on whether busy information is stored when the destination is a telephone terminal housed in the own exchange, and when the destination is a telephone terminal housed in another exchange. This is done using busy information sent from other exchanges. Absence detection is performed by sending out a ringer if the destination is a telephone terminal housed in the local exchange, and setting the timer 2 to send out a ringer.
8, when the predetermined time has elapsed, and if the destination is a telephone terminal housed in another exchange, the call is made when the predetermined time has elapsed after the call information was returned. Absence detection can also be performed by counting the number of ringers using a counter.

The storage unit 19 stores a message indicating that a predetermined service is available when the caller is busy or absent, and instructing the caller to use the predetermined service. Further, the telephone numbers of the caller and the callee, as well as status information (busy information, etc.) of each telephone terminal, are also stored. The storage unit 19 is a semiconductor memory, and the read message information is voice synthesized by a voice synthesis unit 27, which will be described later. The message storage unit 20 is a recording tape for storing a sender's message. The speech synthesis section 27 is connected to the storage section 1
This is a circuit that synthesizes the information read from 9 into speech.

A message sending circuit for notifying the caller by voice that the caller is busy or absent, and also informing the caller that a predetermined service is available, is constituted by the storage section 19, a part of the control section 18, and the speech synthesis section 27. The circuit part corresponds. The calling means includes the storage unit 19, a part of the control unit 18, and the RG.
A circuit portion constituted by the generation unit 24, timer 28, etc. corresponds to this. Detection of the end of a busy call is performed by detecting that the callee during the call goes on-hook and the busy information is deleted.

FIGS. 4 and 5 are flowcharts showing the procedure for receiving help service when the telepoint handset 2 of FIG. 3 makes a call and the other party is busy.

When the handset 2 makes a call and dials the telephone number of the other party, the telephone number is stored in the register 23 connected to the caller via the switch 31, and the telephone number is decoded by the decoder 29 and sent to the control unit. Sent to 18th. Control unit 18
stores the caller's and callee's telephone numbers in the storage unit 19 (step 1). Next, based on the telephone number information, the control unit 18 checks whether the busy information is stored in the storage unit 19 if the destination is a telephone terminal housed in the local exchange, and if the busy information is not stored, the RG generation unit 24 to the destination and sends out a ringer to determine whether or not to respond.If the destination is a telephone terminal housed in another exchange, the telephone number information is sent and busy information is returned. or whether the information being called is returned (step 2).
).

When the control section 18 detects a busy state, the control section 18 stores the memory section 1.
The message information stored in advance in the voice synthesis section 9 is read out, and the voice synthesis section 27 performs voice synthesis of the read message information. The synthesized voice is sent to the handset 2 via the switch 31 and the subscriber circuit. The handset has automatic redial, call reservation, and message recording services.If you want to receive the automatic redial service, select 1.If you want to receive the call reservation service, select 2.If you want to receive the message recording service, select 3. Please press the number.'' (Step 3).

Note that this service can also be received by inputting a predetermined voice or key signal while a call is being detected. In such a case, in the case of a voice input, the voice is temporarily stored in the voice storage section 22 and the voice recognition section 30, and in the case of a key input signal, key information is stored in the register 23, and the instruction content is recognized by the decoder 29.

[0029] The case where automatic redial is selected according to the content of the announcement will now be explained. Caller is "1"
When is pressed (step 4), the message information "Please wait for a while" is read out from the storage section 19, and the information is synthesized into speech by the speech synthesis section 27 and sent to the caller (step 5). The caller will wait in an off-hook state. If the destination is a subscriber of the local exchange, the control unit 18 measures the time using the timer 28 and checks at regular intervals whether the busy information stored in the storage unit 19 has been deleted (step 6). 9). Each time it is checked whether the busy information has been deleted, it is determined whether the caller has gone on-hook, and if the caller has gone on-hook, the line is disconnected (step 7).

It is also determined whether or not "2" or "3" has been pressed, and if it has been pressed, the process moves to a call reservation or message recording service (step 8). When the other party is no longer busy, a ringer is sent, and when a response is received, the communication is connected to the other party (steps 10, 11, and 16).

On the other hand, if the destination is a subscriber accommodated in another exchange, the timer 28 measures the time and sends the other party's telephone number stored in the storage unit 19 to the other exchange at regular intervals. and repeats the call (steps 6 and 14).
, 15). Then, when the other party is no longer busy, a connection is made to the other party (step 16). Next, if you want to select a call reservation service, press "2". According to this operation, the message information "A call reservation has been made. Please hang up the phone and wait." is read from the storage unit 19, and the information is synthesized into speech by the speech synthesis unit 27 and sent to the caller (
Step 17). The caller hangs up the telephone according to the instructions, and it is determined whether the caller has gone on-hook (step 18).

[0032] When the caller goes on-hook, the control unit 18
If the destination is a subscriber accommodated in the local exchange, it is checked at regular intervals whether the busy information stored in the storage section 19 has been deleted (step 20). When the end of the busy call is detected, the RG generator 24 is connected to the other party and a ringer is sent out (step 21). Then, it is detected whether or not the other party responds (step 22), and when a response is detected, the caller is also sent a ringer to call, and the two are connected (step 25).

On the other hand, if the destination of the call is a subscriber accommodated in another exchange, telephone number information is sent to the other exchange at regular intervals (step 23), and it is detected whether the other party responds or not. (Step 24). When the other party responds, a ringer is sent to the caller, and the two parties are connected after waiting for the caller's response (step 25).

Next, the case where message recording is selected will be explained. When the caller presses "3" (step 4), the storage unit 19
"Please say your message after the beep."
message information is read out, and the information is sent to the speech synthesis section 2.
7, the voice is synthesized and sent to the caller (Step 2
6). When the caller speaks the message according to the instructions, the message is stored in the message storage section 20 (step 27). Then, it is determined whether the caller has gone on-hook or not, and when the caller goes on-hook, message storage ends (step 28).

Next, as in the case of the call reservation service, if the destination is a subscriber accommodated in the own exchange, the busy information is monitored at regular intervals, and when the end of the busy call is detected, a ringer is sent to the destination. If the destination is a subscriber accommodated in another exchange, telephone number information is sent to the other exchange at regular intervals (steps 29, 30,
31, 33, 34). Then, the response of the other party is monitored, and when a response is detected, the message stored in the message storage section 20 is read out and sent to the other party (steps 32, 3).
5).

FIG. 6 is a flowchart showing the procedure for receiving help service when the telepoint handset 2 makes a call and the other party is absent. When the handset makes a call and the other party's phone number is dialed, the operations up to determining whether the caller is busy or ringing are the same as up to step 2 of the busy processing flowchart in FIG. 4 (step 1, 2).

If it is detected that the person is being called, it is determined whether or not the person is absent (step 3). This is done by making the timer 28 send out the RBT for a predetermined time period. Note that if the caller goes on-hook during absence detection, the line is disconnected. Also, if the other party responds, the two are connected.

[0038] When the absence is detected, the control unit 18 reads out the message information stored in advance in the storage unit 19, and the voice synthesis unit 27 synthesizes the message with the message information (
Step 4). The synthesized voice is sent to the caller. A message is sent to the handset saying, ``It seems that you are not home. You can receive a message recording service. If you would like to receive it, please press 3.'' Note that this service can also be received by inputting a predetermined voice or key signal during the above call. In such a case, when inputting voice, the voice is temporarily stored in the voice storage section 22 and then transferred to the voice recognition section 30.
Accordingly, in the case of a key input signal, key information is stored in the register 23, and the instruction content is recognized by the decoder 29.

Next, the control unit 18 starts the timer 28 and monitors whether the caller presses "3" within a predetermined time (step 5). If no button is pressed within a predetermined time and the time has elapsed, or if the caller goes on-hook, the line is disconnected (step 6). If the button is pressed within the predetermined time, the message information "Please speak your message after the beep sound" is read out from the storage section 19, and the information is synthesized into speech by the speech synthesis section 27 and sent to the caller. (Step 7).

When the sender speaks a message according to the instructions, the message is stored in the message storage section 20 (step 8). When the caller hangs up the receiver, message storage ends and the line is disconnected (step 9). Thereafter, the control unit 18 reads out the telephone number of the other party from the storage unit 19 at regular intervals, and if the destination is a subscriber accommodated in the own exchange, the control unit 18 captures the subscriber using the read telephone number and sends out a ringer. and call. If the destination is a subscriber accommodated in another exchange, the telephone number information is sent to the other exchange and the call is made. If the other party responds, the message stored in the message storage section 20 is sent (step 10). In addition, as a public network, ISD
It is also possible to apply it to N lines.

[0041]

[Effects of the Invention] As explained above, the present invention is a service that can be received by a caller of a telepoint system.
The public network is provided with a busy detection circuit, an absence detection circuit, a message sending circuit, a recognition means, a calling means, a memory circuit, and a busy end detection circuit, and when the caller is busy or absent, the caller Since the system is configured so that one of the services can be selected according to the instructions, it has various advantages as described below. First, if a subscriber subscribes to Telepoint, all callers can receive help services when a caller is absent, regardless of the terminal of the called party or the service subscribed to.

[0042] Since the system automatically detects whether the user is busy or absent and provides guidance on how to use the service, even those who are completely unfamiliar with this service can easily use it.

[0043] Since this service can be activated by a DTMF signal or voice instruction, the time required for automatic detection can be shortened, and even when automatic detection fails, this service can be activated.

[0044] Furthermore, since the configuration allows you to select one from automatic redial, call reservation, and message recording/transmission services, you can receive a service that suits the circumstances of the caller, and even if the other party is busy or absent. Nevertheless, you can choose the service that takes the least amount of time and communicate your requirements to the other party in a short time.
