Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device such as a facsimile device that effectively utilizes a dial-in service.

[0002]

2. Description of the Related Art Conventionally, private branch exchanges (P
BX) to use the dial-in service. At present, a facsimile device incorporating a dial-in processing circuit has also been developed. By connecting a plurality of telephones to the facsimile device, the facsimile device itself can be used. A different telephone number is assigned to each of the telephone and the telephone.

In recent years, a modem dial-in service has been operated as one of the pre-communication information notification services. If this service is used, the dial-in number can be known before the call signal is received. When a call is received, a designated telephone or the like can be called directly. FIG. 6 is a diagram showing the basic operation of this service. In addition, ~ in the figure is a number assigned to each operation, and the information receiving terminal is
It refers to communication terminal devices such as telephones and facsimile machines that can use this service.

[0004] The subscriber line exchange, when receiving a call from another communication terminal device to an information receiving terminal for which a service contract has been made in advance, a subscriber line L which is a line on the receiving terminal side.
1, the polarity of L2 (telephone line) is inverted (), and an information receiving terminal activation signal is transmitted (). On the other hand, when the receiving terminal is ready to receive information such as a dial-in number (hereinafter referred to as “information etc.”), the receiving terminal closes the DC circuit in the terminal (DC loop is closed) and transmits the primary response signal. Send (). When the exchange determines the primary response signal from the DC resistance value, it transmits information and the like to the receiving terminal by a modem signal (). When receiving the modem signal such as information, the receiving terminal sends a reception completion signal by opening a DC circuit (opening a DC loop) (), and the exchange side transmits the signal such as information within time t. When the reception completion signal is received, a calling signal is transmitted ().

At this time, since the information receiving terminal detects the dial-in number in advance, the line is connected in advance to a telephone or the like to which the number is assigned, and the ringing tone is directly sounded to the user. Prompting a response. On the other hand, if the telephone responds by picking up the handset or the like, the information receiving terminal detects this, and again,
The DC circuit is closed (DC loop is closed) and a secondary response signal is sent out (). After that, when the polarity is restored, a call can be made between the answering telephone and the caller (,
).

[0006] The information transmitted by the modem signal and the like include not only the dial-in number (called number information) but also the source telephone number of the number display service. In the number display service, if the source telephone number cannot be notified other than the source telephone number, the reason is notified. For example, the reason may be that non-notification was designated by an operation (dial "184") before inputting a telephone number, or a call was made from a public telephone.

[0007]

However, in the conventional communication terminal device using the dial-in service, when the function setting of this device is changed from another remote device, the line is once connected, It is necessary to follow the content of the signal transmitted thereafter, and the remote device always incurs a communication fee.

For example, when this apparatus is a facsimile apparatus, when the standby mode is changed from the telephone standby mode to the facsimile reception standby mode, it is necessary to make an operation such as making a call from an outside telephone and transmitting a tone signal. Met. Also, when another remote device retrieves the image data stored in the memory of the device (such a function is referred to as “remote reception”), it is necessary to once connect a line, so that a communication charge is required. However, it did not change.

The present invention has been made in view of such circumstances, and by using a dial-in service, a process according to a dial-in number is executed before a line is connected. It is an object of the present invention to provide a communication terminal device in which a transmission source is not charged a communication fee.

[0010]

In order to achieve the above object, a communication terminal according to a first aspect of the present invention comprises a detecting means for detecting a dial-in number transmitted from an exchange, and a detecting means for detecting a dial-in number transmitted from an exchange. When the detected dial-in number matches a pre-registered dial-in number, after disconnecting the line, control means for executing a pre-registered process corresponding to the registered dial-in number is provided. .

[0011] This communication terminal apparatus uses a modem dial-in service for detecting a dial-in number before a call signal is transmitted, or based on a dial-in number transmitted after the call signal. The present invention is also applicable to a case where a conventional dial-in service for transmitting an extension calling signal to a designated telephone or the like is used. For this reason,
It is necessary to conclude contracts for these services in advance and provide functions corresponding to each service.

In this communication terminal device, the line is disconnected before executing the pre-registered processing, so that the device itself and the connected telephone do not respond to the call. In addition, the communication source is not charged to the transmission source. According to claim 2, in claim 1, further comprising a storage means for storing information to be communicated, wherein the control means performs, as a pre-registered process, a destination registered in advance corresponding to the registered dial-in number; The information stored in the storage unit is transmitted. Thus, the stored information can be transmitted to another communication terminal device simply by dialing the dial-in number of the communication terminal device from a remote place.

[0013] According to a third aspect of the present invention, in the first aspect, the information processing apparatus further comprises a storage unit for storing information to be communicated, and the detection unit further detects a source telephone number transmitted from the exchange. Further, the control means transmits the information stored in the storage means to the source of the detected source telephone number as a pre-registered process. Here, in order to detect the source telephone number transmitted before the call signal, it is necessary to contract for a number display service, and it is necessary to detect the dial-in number before the call signal. Therefore, the dial-in service is limited to the modem dial-in service. As described above, when a plurality of services are contracted as the pre-communication information notification service, information on the plurality of services is simultaneously transmitted from the exchange (see FIG. 6).

In this communication terminal device, when the detected dial-in number coincides with the previously registered dial-in number, the line connection is cut off and the stored information is transmitted to the detected source telephone number. At the source, remote reception can be performed without incurring communication charges.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating an example of a configuration of a communication terminal device. Here, the configuration of the facsimile apparatus F is shown as a communication terminal apparatus. However, the present invention is not limited to this, and any apparatus having a dial-in function may be used. Alternatively, a telephone with an exchange connection function, a personal computer with a communication function, or the like may be used.

The following describes the dial-in function as shown in FIG.
A case will be described in which a function corresponding to the modem dial-in service described above is provided. In the figure, 1 is CP
U and the like constitute control means, and a main control unit for controlling the following units sends a dial signal to the telephone line L, controls the closing and opening of the telephone line L, and further detects a polarity inversion. , A modem for modulating and demodulating signals for performing facsimile communication, 4 for storing an image memory for storing coded image data, and 5 for storing various data necessary for controlling the apparatus F. RAM 6 for performing control programs and the like in advance, and 7 is a liquid crystal screen or LED
A display unit composed of lamps and the like; 8 an operation unit composed of various switches; 9 a reading unit for reading image data from a set original; 10 a facsimile-received image and an image read from the reading unit 9 A recording unit for printing out on a recording paper set in advance, 11 connects a plurality of (n) communication terminal devices such as telephones T1 to Tn and connects the telephone line L based on the dial-in number. The facsimile apparatus F itself or a plurality of telephones T1 to T
n is a dial-in processing unit that controls switching to any one of n.

The facsimile apparatus F encodes the image of the original read by the reading section 9, temporarily stores the image in the image memory 4, sequentially reads the image, and performs facsimile transmission via the modem 3 and the NCU 2. The basic operation of sequentially storing image data facsimile-received from another communication terminal device via the telephone line L in the image memory 4, decoding the image data while reading the data, and recording the data by the recording unit 10 is performed.

If an image or the like read from the reading unit 9 is stored in advance in the image memory 4 constituting the storage means, the image memory 4 can respond to a remote transmission request from another device via the telephone line L. 4 also has a function of transmitting the image (remote transmission function). Further, in the facsimile apparatus F, the function of the modem dial-in service described with reference to FIG. 6 is performed by the main control unit 1, the NCU 2, and the modem 3, and these constitute a dial-in number detecting means. I have. Note that this means is not limited to being built in the facsimile machine F, but may be externally provided as an adapter.

When the main control unit 1 detects a dial-in number transmitted from the exchange via the telephone line L, the dial-in processing unit 11 uses the dial-in processing unit 11 to detect the dial-in number. Is connected to the telephone line L. When the facsimile apparatus F or the telephones T1 to Tn responds to the call signal by transmitting the call signal by automatically receiving the call or picking up the handset, the facsimile communication or the telephone call is started.

The main control unit 1 detects the dial-in number sent from the exchange, and when the detected dial-in number matches the dial-in number registered in advance, the main control unit 1 executes the dial-in processing unit 11. After the connection of the line L is disconnected so as not to receive a call signal without performing connection switching, a process registered in advance corresponding to the registered dial-in number is executed.

Here, the pre-registered processing includes, in addition to the change of the standby mode and other function settings for the apparatus F,
There are remote transmissions and the like, and the processing contents are set and registered in the RAM 5 in advance. When detecting the dial-in number, the main control unit 1 refers to the RAM 5 and determines the execution of the process. For example, when the facsimile apparatus F is provided with an attached telephone, and the user forgets to switch the standby mode from the telephone standby mode to the facsimile reception standby mode when going out, the apparatus F is set to a predetermined mode. By simply making a call from a place where the user is away (such as a workplace), the user can remotely switch the standby mode. Therefore, there is no need for an operation for transmitting a tone signal as in the related art. Before calling (before sending a calling signal), the line L is disconnected.
There is no charge for communication charges.

When the main control unit 1 detects the dial-in number, it performs a pre-registered process that matches the detected number and registers a destination registered in advance corresponding to the registered dial-in number. Alternatively, the information stored in the image memory 4 can be transmitted. As a result, it is possible to instruct a memory transmission to another communication terminal apparatus only by transmitting a signal to the facsimile apparatus F from a remote place.

Further, in the case of remote transmission, the facsimile apparatus F detects a source telephone number transmitted before the calling signal, also under a contract for a number display service. When the modem dial-in service and the number display service are subscribed as the pre-communication information notification service, the dial-in number and the source telephone number are simultaneously transmitted from the exchange as information by a modem signal. (See FIG. 6). Therefore, the main control unit 1, the NCU 2, and the modem 3 also constitute a source telephone number detecting means.

The main control unit 1 detects the dial-in number, and disconnects the connection of the line L when the detected dial-in number matches the dial-in number registered in advance. The detected caller telephone number is called, and the information stored in the image memory 4 is transmitted. As a result, at the transmission source, remote reception can be performed without incurring a communication fee.

FIG. 2 is a flowchart (steps 100 to 109) showing the operation of the facsimile machine F described above. Here, the function of executing the pre-registered processing is called a macro function, and further detects the source telephone number together with the dial-in number (10).
2). When the facsimile machine F receives the information receiving terminal activation signal (FIG. 6) (100), it sends out a primary response signal (FIG. 6) (101), and the dial-in number and the source telephone number (information and the like). (FIG. 6) is detected (102). It is determined whether the detected dial-in number is for a macro function (103). If the detected dial-in number is not for a macro function, a reception completion signal (FIG. 6) is transmitted according to the normal operation of the modem dial-in service (FIG. 6). 10
4) Facsimile machine F corresponding to dial-in number
Connect yourself or any of the phones T1-Tn,
A call signal (of FIG. 6) is received (105). On the other hand, the facsimile machine F itself (NCU2) and the telephone T1
~ Tn (106), as shown in FIG.
Communication and telephone calls can be started.

On the other hand, if the detected dial-in number is for the macro function, after waiting for a predetermined time t (for example, 2 seconds) from the detection of the dial-in number (107), the operation of the modem dial-in service is stopped, and Break the loop (108). This predetermined time t is a waiting time for the reception completion signal on the exchange side, and if the reception completion signal is not detected during this time t, the exchange shifts to the line L disconnection operation, and the subsequent processing in FIG. Do not perform steps.

Since the facsimile apparatus F breaks the DC loop after the elapse of the time t (108),
The exchange does not judge this as a reception completion signal. In this case, since the number display service is also contracted, if the waiting time of the reception completion signal in the exchange differs between the two services, it is necessary to break the DC loop after the longer time has elapsed. There is. Then, after breaking the DC loop, the macro function registered corresponding to the dial-in number is executed (1).
09).

Next, a method for determining whether or not the dial-in number is for the macro function (103 in FIG. 2) will be described with reference to FIG. 3A, 3B and 3C respectively show tables 51 and 5 stored in the RAM 5 in advance.
2 and 53 are configuration examples. A dial-in number for a macro function is registered in the macro table 51 shown in FIG. 3A. When the same dial-in number as the number stored here is detected, the corresponding dial-in number is designated in advance. Perform macro functions.

If this table 51 is used, the image data stored in the image memory 4 can be transmitted (remote transmission) or received in the reception mode only when a call is made to the number registered here. Can be changed. In this case, the image transmission can be registered in the case of transmission to a transmission source or in the case of broadcast transmission. When remote transmission is registered, a box number in the image memory 4 storing image data to be transmitted may be registered in association with the dial-in number.

The destination number table 5 shown in FIG.
2, a destination telephone number is registered. Since “image transmission” is registered in the macro table 51 of (a) corresponding to the dial-in number “001”, when this number is detected, the telephone number registered in the transmission destination number table 52 is registered. The image data stored in the image memory 4 is transmitted for the number. If a plurality of "image transmissions" can be registered in the macro function specification of the macro table 51, the transmission destination telephone number is stored in the transmission destination number table 52 in correspondence with each dial-in number to be specified. You may make it register.

In the broadcast destination number table 53 shown in FIG. 3C, a plurality of broadcast destination telephone numbers are registered. Since “image transmission (broadcast)” is registered in the macro table 51 of (a) corresponding to the dial-in number “003”, the broadcast destination number table 53 is detected when this number is detected. The image data stored in the image memory 4 is sequentially transmitted to each of the telephone numbers registered in. When a plurality of “image transmission (broadcast)” can be registered in the macro function designation of the macro table 51, the broadcast destination number table 53 is associated with each dial-in number to be designated. Alternatively, a plurality of broadcast destination telephone numbers may be registered.

Next, FIG. 4 shows a table 5 shown in FIG.
The operation when executing the macro function by using 1 to 53 is shown by a flowchart (steps 200 to 209). The detected dial-in number is for the macro function (registered in the macro table 51), and when executing the macro function (109 in FIG. 2), the macro table 51 refers to the macro function designation corresponding to the dial-in number (200). ).

The designation is image transmission (Y of 201), individual transmission other than broadcast transmission (N of 202),
If the transmission is to the transmission source (Y of 203), the image in the image memory 4 is transmitted to the transmission source telephone number (20).
4) If the transmission is not to the transmission source (N of 203), the image in the image memory 4 is transmitted to the telephone number in the transmission destination number table 52 (205). If it is a broadcast transmission (Y in 202), the images in the image memory 4 are sequentially transmitted to the telephone numbers in the broadcast destination number table 53 (206).

In the above description, the destination of the image transmission is
Although an example in which the telephone number is used has been described, the present invention is not limited to this, and the designation of the destination may be an e-mail address. In this case, a call is made to the provider, and the e-mail address registered in the destination number table 52 or the broadcast destination table 53 or the source e-mail address included in the information (FIG. 6) is stored in the image memory. 4 will be transmitted as mail.

When the macro function designation is not image transmission (N of 201), since the designation is to change the reception mode, the current reception mode is referred to (207), and the current reception mode is set to the home mode. If so, it sets the absence mode (208), and if it is the absence mode, it sets the home mode (209). Normally, the dial-in function is executed in the home mode, and the facsimile reception or answering machine function is executed in the absence mode.

In the above, the case where the modem dial-in service for detecting the dial-in number before the calling signal is transmitted is used as the dial-in function has been described. The present invention can also be applied to the case where a conventional dial-in service is used in which an extension calling signal is transmitted to a designated telephone or the like based on the dial-in number received.

FIG. 5 is a diagram showing the basic operation of this service. Here, a case will be described in which the communication terminal device having the dial-in function is the facsimile device F having the configuration shown in FIG. Note that “〜” in the figure is a number assigned to each operation. The subscriber line exchange, when receiving a call from another communication terminal device to the device F for which a service contract has been made in advance, the subscriber lines L1 and L
2 (the telephone line L) is inverted () and a calling signal is transmitted (). On the other hand, when the device F becomes ready to receive the extension designation signal (dial-in number), the device F closes the DC circuit in the device F (closes the DC loop) and sends out a primary response signal (). . When the exchange determines the primary response signal from the DC resistance value, it transmits an extension designation signal to the device F by a PB signal (push button signal) (). When receiving the PB signal, the device F sends an extension designation reception completion signal by opening the DC circuit (DC loop opening) (). At the same time, the device F decodes the PB signal,
Device F to which the specified extension number is assigned
It connects itself or the telephone set T1 to Tn to the line L, sends out an extension calling signal, sounds a ringing tone, and prompts the user to answer. On the other hand, if the exchange receives the extension designation reception completion signal within time t1 (for example, 2 seconds) after transmitting the extension designation signal, the exchange sends a ringing tone to the calling side.

When the facsimile machine F detects the response of the called machine F itself or the telephone set T1 to Tn, it closes the DC circuit again (closes the DC loop) and sends a secondary response signal (). , The polarity is reversed,
Communication or telephone conversation can be performed between the responding facsimile machine F or the telephones T1 to Tn and the caller.

In order to fulfill the above functions, the dial-in processing section 11 of the facsimile apparatus F is provided with means for detecting a PB signal and means for generating an extension calling signal, in addition to controlling the switching of the connection to the line L. ing. Main control unit 1
Detects the extension designation signal (dial-in number) sent from the exchange, and when the detected dial-in number matches the dial-in number registered in advance, as in the case of the modem dial-in service, The connection is not switched by the dial-in processing unit 11 and the time t1
After disconnecting the line L after elapse, the processing registered in advance corresponding to the registered dial-in number is executed.

The pre-registered processing is to store the image memory 4 in the destination that matches the detected dial-in number and is registered in correspondence with the pre-registered dial-in number.
Can be transmitted. If you do not have the number display service function,
The source phone number cannot be detected by the modem signal, but as the destination corresponding to the dial-in number,
If the source telephone number is registered in advance, the image stored in the image memory 4 can be transmitted to the source.

[0041]

As can be understood from the above description, the communication terminal device according to the first to third aspects of the present invention is characterized in that the dial-in number transmitted from the exchange has a dial-in number registered in advance. When it matches, the process registered in advance corresponding to the dial-in number is automatically executed. Therefore, the sender can remotely control the device simply by calling the predetermined dial-in number of the device. In addition, since the line is disconnected and a pre-registered process is executed before responding, the transmission source does not bear the communication fee.

In particular, when the detected dial-in number matches a previously registered dial-in number, the information previously stored in the destination registered corresponding to the dial-in number is transmitted. Since transmission is performed, the transmission source can instruct remote transmission to another communication terminal device without incurring a communication fee. Also,
According to the third aspect, when the detected dial-in number matches the previously registered dial-in number, the information stored in advance is transmitted to the further detected caller telephone number. Remote reception can be performed without paying a fee.
