Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a telephone device,
In particular, the present invention relates to a telephone device for outputting a dial number transmitted in the past in response to a redial operation to a telephone line.

[0002]

2. Description of the Related Art In a public telephone network, various services are provided to a subscriber, such as a call destination notification service. For example, the call termination notification service of a calling party is such that when the calling party is busy, a predetermined registration operation is performed from the calling telephone device to the network, so that the subsequent call termination is transmitted from the network to the calling telephone. This service notifies the device.
Hereinafter, with reference to FIG. 9 to FIG. FIG. 9 is a sequence diagram showing the operation of the call destination end notification service, FIG. 10 is a signal waveform diagram showing an incoming signal at the time of call destination end call notification, and FIG. 11 is a timing chart of the call destination end call notification. .

In FIG. 9, a calling telephone device and a called telephone device are respectively connected to a telephone network via telephone lines. First, it is assumed that the caller telephone device captures the telephone line in accordance with the operation of the user and dials out the telephone number of the callee, ie, the receiver telephone device, to make a call to the receiver telephone device (step 70). . In response to this, the telephone network checks the status of the receiving telephone device, and if the receiving telephone device is seizing the telephone line and cannot call, such as when the other telephone device is busy, the calling telephone device Is notified that the receiving-side telephone device is in use by a busy tone (BT) or the like (step 7).
1). Then, the calling telephone device disconnects the telephone line (step 72).

[0004] Here, when the user wants to make a telephone call to the called side, the user performs a service registration operation in order to use the caller's end-of-call notification service. First, the calling telephone device captures the telephone line and sends out a dial "159" (step 73). As a result, a voice message regarding the contents of the service is notified from the telephone network (step 74). Then, by sending a dial "1" for instructing service registration from the calling side telephone device, service registration is performed (step 75), and a voice message regarding completion of service registration is notified from the telephone network (step 76). ), The registration process of the call destination end call notification service ends.

[0005] Thus, in the telephone network, the destination communication end call notification service is started, and in response to the registered call termination of the called telephone device, the calling telephone device is called by an SIR incoming call described later (step). 80). When the originating telephone device responds to this SIR call (step 81), a voice message regarding the termination of the receiving telephone device is notified from the telephone network (step 82). As a result, the user knows that the receiving-side telephone device has ended the call and is ready to call, and once disconnects the telephone line (step 83).

Subsequently, in order to instruct retransmission from the network side using this service, the telephone line is recaptured and dial "159" is transmitted (step 84).
A voice message about the contents of the service from the telephone network is notified (step 85). Then, a dial "3" is transmitted from the calling telephone device to the network side to instruct retransmission to the called party (step 86), so that the telephone network calls the called telephone device (step 87). ), In response to a response from the called telephone device (step 8).
8) The originating telephone device and the receiving telephone device are connected via the telephone network, and a call between them is started (step 89).

[0007] When the user registers such a call destination end call notification service on the network side, the call end telephone device can know the end of the call receiving telephone device. In addition, it is possible to call the receiving-side telephone device by a simple operation after the notification of the outgoing call destination from the telephone network.

[0008] In this call destination end call notification service, when the call end is notified from the telephone network to the calling telephone device, as shown in FIG.
IR termination is used. At the time of an incoming call, a frequency signal of 16 Hz is used in the analog telephone line, and the ringing pattern of the IR incoming call has an ON period of 1 as shown in FIG.
, And the frequency signals 90, 91,... Of such a pattern are repeated in a cycle of 3 seconds.

On the other hand, in the ringing pattern of the SIR incoming call, as shown in FIG. 10B, after a short ON period (t1 = 0.25 to 0.3 seconds) 95A of the frequency signal,
There is a short off-period (t2 = 0.25 to 0.3 seconds) 95B, and an even shorter on-period (t1 = 0.25 to 0.3 seconds).
95C is provided. Then, patterns 95 and 9 composed of two ON periods sandwiching such a short OFF period
6,... Are repeated every 12 seconds (about 36 seconds).

In the telephone network, assuming that the originating telephone device cannot respond to such an SIR reception for some reason, as shown in FIG. 11, a 5-minute interval (T2) from the first SIR reception. A maximum of four times is used to make a call to the calling telephone device using the SIR reception. At this time, S
The transmission period of the dial "3" following the transmission of the dial "159" after the response to the IR reception, the period during which the call can be redialed from the telephone network is 5 seconds from the response to the SIR reception in consideration of the reduction of the telephone network side load. Limited to a minute. Further, when the response to the SIR call arrives, it is considered that the caller's end-of-call notification service has been completed. Therefore, for example, when responding to the first SIR call, the remaining three SIR calls are terminated.

When monitoring the call termination of the destination telephone device, a period during which the call termination of the destination telephone device is monitored, that is, the waiting time (T
1) is limited to 45 minutes from the point of service registration. As a voice message from the telephone network to the calling telephone device, a registration completion notification message (M
In addition to 1), there is an end-of-call notification message (M2) that is sent out when the calling telephone device responds to the SIR call. If the other party's call waiting time (T1) exceeds 45 minutes, a service end notification message (M3) is sent out when responding to the first SIR call.

In the call destination notification service, when the service is registered, a fee for the service is charged to the telephone line of the caller. Also, during a period in which the service registration is valid, that is, during a period in which the telephone network is monitoring the end of the call destination, the line is captured and the dial "159" is transmitted followed by the dial "8". You can check the phone number of the registered destination. In addition, in the call destination call end notification service, only one call destination can be registered on one telephone line. This is the same for the registered party, that is, the destination, and the registration is not duplicated from a plurality of sources. Note that, by capturing the line and sending out the dial “9” following the dial “159”, it is possible to cancel the setting of the call destination already registered.

[0013]

However, in such a conventional telephone device, for example, when using the above-mentioned call termination service of the called party, the dial "15" is used.
Since a service-specific dial number consisting of "9" and a one-digit number following this is sent to the telephone line, these service-specific dial numbers are stored as redial information of the telephone device, and the user's There is a problem in that a service-specific dial number not intended by the user is transmitted to the telephone line in response to the redial operation. An object of the present invention is to solve such a problem, and an object of the present invention is to provide a telephone device that can prevent transmission of a service-only dial that is not intended by a user even after using a network-side service. .

[0014]

In order to achieve such an object, a telephone device according to the present invention registers dial data dialed at the time of outgoing call in a redial storage means and performs redial operation. A telephone device for transmitting a dial number corresponding to the dial data registered in the redial storage means to the telephone line in response to the dial data inputted at the time of dialing and a specific dial number; If the comparison means determines that the dial data matches the specific dial number, the registration means does not register the dial data in the redial storage means.

As a specific example of dial data comparison at the time of outgoing call, a temporary storage means for updating and storing a series of dial data input so far each time a dial is input one digit at a time of outgoing call. Further, each time one digit of dial data is input by the comparing means,
The dial data stored in the temporary storage means may be compared with a specific dial number. In addition, each time a dial is input one digit at a time of a call, a temporary storage means for updating and storing a series of dial data input so far in the call is further provided. After the end, the dial data stored in the temporary storage means may be compared with the specific dial number. As a specific example of the dial data comparison at the time of disconnection, a temporary storage unit that updates and stores a series of dial data input at the time of calling is further provided, and the comparing unit releases the telephone line captured by the calling. Alternatively, the dial data stored in the temporary storage means may be compared with a specific dial number.

In another telephone apparatus according to the present invention, dial data inputted by dialing at the time of outgoing call is registered in a redial storage means, and the dial data registered in the redial storage means is stored in response to a redial operation. In a telephone device for transmitting a corresponding dial number to a telephone line, a comparing means for comparing the last used dial data registered in the redial storage means with a specific dial number in response to a redial operation; If it is determined that the dial data matches the specific dial number, there is provided dial sending means for not sending the dial data to the telephone line.

As a specific example of storing a plurality of redial data, a plurality of dial data used in the past are stored by a redial storage unit, and a comparison unit determines by comparison that the dial data matches a specific dial number. May compare the specific dial number with the dial data used immediately before the dial data used for comparison from the redial storage means.

In the above-described telephone device, a service-specific dial number which is dialed when using various services provided from the network side may be used as the specific dial. Furthermore, a service-specific dial number that is dialed in when using various services provided from the network side as a specific dial, and for which a service fee is charged in accordance with transmission of only the service-specific dial number. A dedicated dial number may be used. Specifically, as the specific dial, a registration instruction dial number for instructing service registration of the call termination communication service provided from the network side may be used.

A known technique can be used as a method for distinguishing and detecting IR incoming (normal incoming) and SIR incoming (special incoming). When the telephone line is an analog telephone line, as shown in FIG.
Because the ringing pattern is different from the incoming call, its 16Hz
The length of the frequency signal, that is, the length of the ON period, may be measured.

At the time of this incoming call detection, not only the on-period of the frequency signal but also the off-period length of the frequency signal is measured, so that even if the incoming signal transmission is started in the middle of the on-period, the IR incoming is regarded as the SIR incoming. Misjudgment does not occur, and an IR incoming call and an SIR incoming call can be accurately identified and detected. In addition, by checking the time length of the off period of the frequency signal, the incoming call can be detected earlier as compared with the case where the determination of the SIR call is made based only on the time length of the on period of the frequency signal. Thereby, the possibility that the SIR reception and the line transmission operation by the user occur almost simultaneously can be reduced, and confusion of the user due to the collision between the SIR reception and the line transmission operation can be reduced.

Although the telephone device and the key telephone device connected to the analog telephone line have been described above, the present embodiment is applicable not only to the telephone device connected to the analog telephone line but also to the ISDN line for performing digital data transmission. The present invention can also be applied to a connected telephone device or key telephone device. ISD
In the N line, call control such as incoming call and outgoing call is all performed by control messages exchanged with the network side. In particular, at the time of an incoming call, a call setting message is transmitted from the network side. The network-specific facility (ne
By referring to information from the network side called twork-specific facilities), it is possible to identify whether the incoming call is an IR incoming call or an SIR incoming call. In addition, the response from the caller and the busy state can be confirmed by a response message and a disconnection message from the network side.

Next, the operation of the first embodiment will be described with reference to the drawings, taking the single telephone apparatus for an analog telephone line shown in FIG. 1 as an example. First, the redial registration processing will be described with reference to FIG. FIG. 5 is a flowchart showing the redial registration process. In the telephone device of FIG. 1, when the user captures the analog telephone line L by, for example, an off-hook operation and inputs the dial number of the destination by pressing the dial key 9, the control circuit 1
Then, the redial registration process shown in FIG. 5 is executed.

First, a dial input is fetched one digit at a time from the dial key 9 (step 100), and the dial data corresponding to the dial input is stored at the end of the dial data stored in the temporary area (temporary storage means) of the memory 11. These are sequentially stored as digits (step 101). In the memory 11, in addition to a redial area (redial storage means) for storing redial data, a temporary area for checking whether the input dial number is a service-specific dial number used for network-side services. Is provided. As the temporary area, an internal memory provided inside the control circuit 1 may be used because the storage capacity is small. Also, as a method of storing and managing a plurality of redial data, a method of managing the storage position of the latest redial data with a pointer, fixing the storage position of the latest redial data, and storing the past redial data according to the occurrence of the latest redial data. Are sequentially shifted, and the present invention can be applied to both cases.

The dial data stored in the temporary area includes one or more service-specific dial numbers registered in the memory 11 in advance, for example, a dial “159P1” used for service registration of a caller's end-of-call notification service.
Is compared with (Step 102). If the dial data stored in the temporary area does not match the service-specific dial number (step 102: NO),
The dial data in the temporary area is stored as the latest redial data in the redial area (step 103),
The process proceeds to a check as to whether dial input has been completed (step 104). If the dial data stored in the temporary area matches the service-specific dial number (step 102: YES), step 104 is continued.
Move to.

In step 104, it is checked whether or not dial input has been completed. For example, when an operation other than the dial input is performed, or when the pressing interval of the dial key 9 exceeds a threshold value, it is determined that the dial input is completed.
Here, if the end of the dial input is not confirmed (step 104: NO), the process returns to step 100 to perform the processing including the next digit. If the end of the dial input is confirmed (step 104: YES), the temporary area is cleared (step 105), and a series of processing ends.

As described above, when registering the dial data inputted as dial data as redial data, it is checked whether or not the dial data matches the service-only dial used in the network-side service. If the redial data is a service-only dial, Because we did not register the redial data, even after using the network side service,
It is possible to prevent a service-specific dial that is not intended by the user from being erroneously transmitted. Further, by this, only valid dial data other than the service dedicated dial is registered as the redial data, and even in a general redial operation processing of reading out the latest redial data and sending out the dial, the user can do so. It is possible to make a call using intended redial data.

Next, the operation of the second embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing another redial registration process. In the first embodiment, a case has been described as an example where the service data dial is checked when a single digit of dial data is input.
In the present embodiment, a check is made after a series of dial inputs is completed. First, the control circuit 1
Fetches the dial input one digit at a time from the dial key 9 (step 110), and stores the dial data corresponding to the dial input as the last digit of the dial data stored in the temporary area of the memory 11 (step 111). ).

Subsequently, it is checked whether or not the dial input is completed (step 112). If the dial input is not confirmed (step 112: NO), the process returns to step 110 to acquire the next digit. If the end of the dial input is confirmed (step 112: YE
S), the dial data stored in the temporary area is compared with one or more service-specific dial numbers registered in the memory 11 in advance (step 113).

Here, only when the dial data stored in the temporary area does not match the service-specific dial number (step 113: NO), the dial data in the temporary area is stored in the redial area as the latest redial data (step 113). Step 114). After that, the temporary area is cleared (step 115), and the series of processing ends. As a result, similarly to the above-described embodiment, even after using the service on the network side, it is possible to prevent a service-specific dial that is not intended by the user from being erroneously transmitted. Further, only valid dial data other than the service dial is registered as the redial data. Even in the general redial operation processing of reading out the latest redial data and sending out the dial, the redial operation intended by the user is performed. It is possible to transmit using data. The comparison between the dial data stored in the temporary area and the service-specific dial number is one.
And the processing time can be reduced even when comparing with a large number of service-specific dial numbers.

Next, the operation of the third embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing another redial registration process. In the first and second embodiments, the case where the redial registration process is performed at the time of outgoing call is described as an example. In the present embodiment, the case where the redial registration process is performed at the time of disconnection of the telephone line after the call operation is described.

The control circuit 1 controls the dial circuit 4
The dial data corresponding to the dial number transmitted to the analog telephone line L from is stored in the temporary area. Thereafter, when disconnection of the analog telephone line L by the user, for example, on-hook is detected by the hook switches HS1 and HS2, dial data is read from the temporary area of the memory 11 (step 120), and the dial data and the dial data are registered in the memory 11 in advance. The number is compared with one or more service-specific dial numbers (step 121).

Here, only when the dial data stored in the temporary area does not match the service-specific dial number (step 121: NO), the dial data in the temporary area is stored in the redial area as the latest redial data (step 121). Step 122). Thereafter, the temporary area is cleared (step 123), and a series of processing ends. As a result, similarly to the above-described embodiments, even after using the service on the network side, it is possible to prevent a service-only dial that is not intended by the user from being erroneously transmitted. Further, only valid dial data other than the service dial is registered as the redial data. Even in the general redial operation processing of reading out the latest redial data and sending out the dial, the redial operation intended by the user is performed. It is possible to transmit using data. The comparison between the dial data stored in the temporary area and the service-specific dial number is one.
And the processing time can be reduced even when comparing with a large number of service-specific dial numbers.

Next, the operation of the fourth embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing the redial operation processing. In the first to third embodiments, a case has been described as an example in which dial data that matches a service-specific dial number is not registered as redial data at the time of redial registration. However, in the present embodiment, when redial data is used, Is to be checked. Hereinafter, a case where a plurality of redial data are stored and managed using a pointer will be described as an example.

When the control circuit 1 detects that the redial operation has been performed by pressing the redial button of the function key 10, the control circuit 1 starts the redial operation processing shown in FIG. First, a pointer for managing the storage position of the redial data is set to the latest redial data in the redial area of the memory 11 (step 130). Then, redial data is read from the redial area indicated by the pointer (step 131), and the redial data is compared with one or more service-specific dial numbers registered in the memory 11 in advance (step 13).
2).

If the read redial data matches the service-specific dial number (step 132: YES), the pointer is set to the immediately preceding redial data (step 133), and the flow returns to step 131 to return to 1 Check the last redial data. In step 132, if the read redial data does not match the service-specific dial number (step 132: NO), the redial data is used only if the redial data is not empty (step 134: YES). Make a call (step 135),
A series of processing ends. If the redial data is empty (step 136), the flow shifts to dial input waiting (step 136), and a series of processing ends.

As described above, the read redial data is checked not at the time of redial registration but at the time of redial operation, and if the redial data is a service-only dial, the redial data is not transmitted. As in each embodiment,
It is possible to prevent a service-specific dial that is not intended by the user from being erroneously transmitted. Further, only one comparison between the dial data and the service dedicated dial number is required, and the processing time can be shortened even when comparing with a large number of service dedicated dial numbers. In addition, if the read redial data matches the service-only dial, until redial data other than the service-only dial is found,
Since the immediately preceding redial data is repeatedly read and checked, it is possible to make a call using the redial data intended by the user.

In each of the embodiments described above, the registration instruction dial number “159” for instructing service registration in the call destination end-call notification service is used as a service-specific dial number that does not perform redial registration or redial transmission.
Although the case of using "P1" has been described as an example, the present invention is not limited to this, and another dial number may be used. Also, by registering a dial number such as the registration instruction dial number, which is charged only by sending the dial number to the network side, as a service-specific dial number, the unintended charging of the user can be prevented beforehand. Can be prevented.

[0057]

As described above, according to the present invention, dial data dialed at the time of outgoing call is compared with a specific dial number, and if it is determined that the dial data matches the specific dial number, dialing is performed. The data is not registered in the redial storage means. Also, in response to the redial operation, the last dial data registered in the redial storage means is compared with the specific dial number, and if it is determined that the dial data matches the specific dial number, the dial data is transmitted to the telephone. It is not sent to the line. Therefore, even after using the service on the network side, it is possible to prevent a service-specific dial that is not intended by the user from being erroneously transmitted.
