Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving device and a transmitting device, and more particularly, to specifying one receiving device from a plurality of receiving devices connected to a communication line so as to be able to make a call using one destination information. To make and receive calls from the transmitting device.

[0002]

2. Description of the Related Art Conventionally, communication devices have been connected via communication lines and signals have been exchanged between the communication devices. Even between users at remote locations, for example, via telephone lines. A telephone call can be made, and data communication can be made with a facsimile machine or the like.
In addition, communication via a network such as a LAN is now generally performed due to the recent advancement of communication technology.

[0003] As this communication device, it is common to perform communication by specifying one receiving device from a transmitting device based on destination information such as a telephone number or an address on a network. For example, the communication device is connected to a telephone line. In the case of the data communication device described above, when functioning as a transmitting device, the receiving device is specified by a telephone number (destination information) and a call is made.
When functioning as a terminating device, by responding to ringing (incoming call) by the calling, data communication is performed by controlling calling and receiving between the calling device and the terminating device.

[0004]

However, in such a conventional communication device, in order to make a call from a transmitting device to a receiving device, individual destination information is added to the receiving device. The problem is that it is not possible to use a plurality of receiving devices with one piece of destination information, and there is a restriction on the connection capability of a local line or a network even if different destination information is given to a receiving device. There is.

[0005] In the case of telephone lines, a service called dial-in is provided which enables a telephone having an individual telephone number to be connected with a small number of lines. This service is specified by the telephone line network side and by the caller side. The relayed telephone number is notified to the relay device and connected to each telephone. A special relay device is required, and the number of telephones that can receive the service is limited.

Accordingly, it is an object of the present invention to improve the usability of a communication line by making it possible to easily use a plurality of receiving devices with one piece of destination information without limitation due to connection capability and the like. .

[0007]

According to one aspect of the present invention, there is provided a terminating apparatus connected to a communication line to detect an incoming call caused by a call from a destination and perform incoming call control. Detecting means for detecting an incoming call period, setting means for presetting an incoming call period, and an incoming call detected at the time of incoming call without performing incoming call control for incoming calls after the standby state. Judgment means for comparing the period with the set incoming call period to judge whether or not it is the target of the incoming call, and responding to the incoming call immediately after it is determined that it is the target of the incoming call, and starting the incoming call control And control means for performing the control.

According to a second aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the detecting means is constituted by a counting means for counting the number of ringings or a time measuring means for measuring a ringing time with a ringing period as a call receiving period. On the other hand, the setting means sets the number of ringings or the ringing time detected by the detection means as an incoming call period.

According to a third aspect of the present invention, in addition to the configuration of the first or second aspect, the control means sets in advance a time until an incoming call after it is determined that the call is to be received. When the predetermined interval is exceeded, the apparatus returns to the standby state. In the invention according to claims 1 to 3, the incoming call device does not respond when it detects an incoming call before it becomes a target of an incoming call or in a standby state after the incoming call control ends and the communication connection is disconnected. The number of times the ringing continues and the incoming call period of time are detected, and if the detected incoming call period matches the set incoming call period and is determined to be the target of the incoming call, A response is made and the incoming call control is started. Therefore, even when a plurality of receiving devices are responsively connected to one piece of destination information, by setting individually different incoming call periods in advance, a period during which a calling device automatically or manually initiates a call can be connected. By simply resuming the call after terminating the call once as the call receiving period of the desired terminating device, the terminating device can be determined to be the target of the incoming call and responded.

If the time for waiting for the next incoming call exceeds the set interval after judging that the call is to be received, the judgment is canceled and the process returns to the standby state. Therefore, if the calling device accidentally quits the call during the period corresponding to the set incoming call period, or if another receiving device responds by going off-hook, etc. The possibility of starting the incoming call control can be reduced.

According to a fourth aspect of the present invention, there is provided an originating apparatus which is connected to a communication line and performs originating control in response to a response to an incoming call of a destination, wherein one or more originating periods are set in advance. Possible setting means, and when there is an outgoing call command specifying the other party, after making a call for a set period corresponding to the other party, making a call to the same other party and responding to the other party's response And control means for starting transmission control in response to the request.

According to a fifth aspect of the present invention, in addition to the configuration of the fourth aspect, the number of ringings or the ringing time is set as the calling period in the setting means. According to a sixth aspect of the present invention, in addition to the configuration of the fourth or fifth aspect of the invention, when the control unit makes a call for a set period, the control unit transmits the other party before the call for the set period ends. When there is a connection for the previous response, a message requesting that the response to the next incoming call be refrained is sent out, and the call for the set period is made again.

According to the present invention, in the transmitting device, the number of times and the number of times that the ringing continues for the set period corresponding to the other party only by specifying the other party and issuing the transmission command are specified. After the call is made, a call is made from the same destination, and transmission control is started when the receiving device of the destination answers. Therefore, a specific receiving device can be set as a destination from among a plurality of receiving devices that can respond with one destination information.

Further, even if another receiving device responds by off-hook or the like before the outgoing call for the set period corresponding to the specified receiving device ends, the next incoming call responds by off-hook or the like. A message requesting not to be sent is sent, and the call is made again for the set period. Accordingly, it is possible to prevent a telephone or the like other than the specified receiving device from being repeatedly off-hook, thereby preventing communication with the receiving device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 to 3 show a first embodiment of a receiving device and a transmitting device according to the present invention, and this embodiment corresponds to the first to fifth aspects of the present invention. In FIG. 1, reference numeral 10 denotes a data communication device communicably connected to a host device H such as a PC via a communication network (communication line) N, and the data communication device 10 holds data from the host device H. Then, data processing and communication, such as returning the data in response to a request, or processing and returning the received data, can be performed. This data communication device 10
It does not limit the type of data processing / communication,
By building the known data processing unit 100, the CP
U11 uses the RAM 13 for storing various information such as driving conditions and management data of each unit of the apparatus as a work area in accordance with a control program in the ROM 12 connected via the bus line B as a work area. In addition to executing data processing, various processing of the present invention is executed. That is, the data communication device 10 of the present embodiment
Is not characterized by what kind of data processing / communication is performed, but may be constructed as, for example, a facsimile device or a database device. In addition, CPU
11, ROM 12 and RAM 13 are provided with input / output ports (I / O
And a well-known microcomputer connecting these together with a bus line B together with the port 14.

The CPU 11 is a transmission / reception control unit 15 that performs communication connection with another device (hereinafter, referred to as a host device H) via the communication network N and communication control such as a predetermined communication procedure.
Is connected via an input / output port 14, and the transmission / reception control unit 15 detects an incoming call by ringing (call signal) from the communication line network N by a calling operation performed by the host device H and can communicate. After the connection control is performed, the incoming call control of a predetermined communication procedure is executed. On the other hand, when data transmission is performed from the data communication device 10, the transmission / reception control unit 15 calls the host device H via the communication network N by a call operation performed by a display operation unit (not shown). Executes data transmission (transmission) control.

As shown in FIG. 2, the data communication apparatus 10 can be connected to the communication network N in a parallel connection form (bus connection form) so as to be responsive to the same destination number. In this connection type, the data communication devices 10A to 10C simultaneously detect ringing in response to a call from the host device H. For this reason, the data communication device 10
The number of times of ringing detected by the transmission / reception control unit 15 can be set in the AM 13 in advance.
As shown in the flowchart, when an incoming call is received during a standby state waiting for a call from the host device H (step P1), the transmission / reception control unit 15 controls connection (response).
Is performed, the ringing detected by the transmission / reception control unit 15 is counted until the incoming call ends (steps P2 and P3),
When the counted (detected) number of ringings matches the set value (incoming call period) in the RAM 13 (step P4), it is determined that the call is a call to the own device (target of an incoming call) and is set in advance. The host device H continues within the time (interval)
When ringing (incoming call) due to the calling operation performed in step (P5, P6) is detected (steps P5 and P6), a response process is performed without restricting the connection control of the transmission / reception control unit 15 (step P5).
7) After the incoming call control, perform data processing and communication requested by the host device H (step P8). Therefore, the data communication device 10A shown in FIG.
Even if the connection is made as 10C, if communication with any one of them is desired, the call is temporarily stopped at the number of ringings corresponding to each incoming call period at the time of calling, and then the same destination number is continued. Data communication can be performed simply by calling again.

Further, the CPU 11 determines in step P4 that the call is not a call to its own device, or the interval from the determination in step P6 that the call is to its own device to the next incoming call is the set time. If it has exceeded, or if the data processing / communication requested by the host device H in step P8 has been completed, the process returns to the standby state. Therefore, by executing Step P6, even if the original call is accidentally terminated by the set number of ringings by mistake due to an erroneous operation by the host device H or another device, it is rare that the call is continuously received. Because of this, it is possible to reduce the possibility that the incoming call control is erroneously started by the next incoming call after a certain time has elapsed.

That is, in the data communication device 10, the RAM
13 constitutes setting means, and the CPU 11 constitutes judgment means and control means together with counting means as detection means.
On the other hand, the host device H receives the data communication device 10 as a destination.
A to 10C are registered in advance in a RAM (setting means) (not shown), and the same number is set as the destination number, but the number of ringings is set as a calling period corresponding to each of them, and When any one of the data communication devices 10A to 10C is selected and designated as a destination to request data processing / communication by operating means such as a keyboard or a keyboard, the CPU (control means) generates a ringing frequency corresponding to the destination. After a call is made, the call is temporarily interrupted and then a call is made again. Therefore, by this calling operation, when there is a response from the other party to the second outgoing call, connection control and outgoing control are performed to perform data processing and communication. Data communication can be performed with a specified partner among the communication devices 10A to 10C. Note that the number of times of ringing for each of the data communication devices 10A to 10C is set in advance, but it is needless to say that the user may manually input each time or listen to the ringing by handset while performing the operation manually.

The host device H and the data communication device 10
The number of ringings set in A to 10C is, for example, 12 times for the data communication device 10A and 14 times for the data communication device 10B even when only the data communication device 10 is connected in parallel.
By setting a large value such as 16 times, 5 times or 10 times or more in the data communication device 10C, even if the user interrupts the call due to erroneous operation in the host device H, the call to the own device can be made. It is possible to reduce erroneous determination, and even if it is erroneously determined to be a call to the own device, the data communication apparatus 10 determines from the determination that the call is to the own device until the next incoming call. It is possible to prevent a response to the next incoming call due to the elapse of the interval. Also,
The ringing frequency set for the data communication devices 10A to 10C is set to the data communication device 10A when the host device H automatically calls when only the data communication device 10 is connected in parallel as in the present embodiment. Twice, data communication device 10
It goes without saying that a small number of times, such as four times for B and six times for the data communication device 10C, may be set.

The interval from when the data communication apparatus 10 sets a call to its own apparatus to when there is a next incoming call is set to an interval at which the host apparatus H can continue to make a call. For example, when the host device H makes an automatic call, the time may be set to 10 seconds, for example, and when a call is made by a manual operation of the host device H, the time that can be manually input may be set to 30 seconds or the like.

As described above, in the present embodiment, a plurality of data communication apparatuses 10 can be connected to one destination number without restriction, and can be easily used properly with a simple configuration. When the time is long, it is possible to reduce the possibility of returning to the standby state and erroneously responding to an unrelated incoming call. In the host device H, call control may be manually performed, but the data communication device
The desired data communication device 10 can be easily used simply by setting the number of ringings for each of 10A to 10C as a calling period in advance.

As another aspect of the present embodiment, as shown in the flowchart of FIG. 4, a ringing time is set in the RAM of the data communication device 10 and the host device H instead of the number of times of ringing, and the host device H Makes a call during the ringing time, while the data communication device 10 provides the CPU 11 with a ringing time until the call is terminated in steps P2 and P3 (time counting means).
The time may be measured and detected. Also in this configuration, the requested data processing / communication can be performed with the specified data communication device 10 by the same processing in steps P4 to P8. Further, according to this configuration, even if the error of the number of times of ringing to be detected is large in order to count ringing one by one, the data communication device 10 receives the call during the calling period of the host device H. The period can be accurately detected with a small error.

Next, FIG. 5 is a diagram showing a second embodiment of the receiving device and the transmitting device according to the present invention, and this embodiment corresponds to the invention described in claim 6. Note that, since the present embodiment is configured substantially in the same manner as the above-described embodiment, the characteristic portions will be described with reference to FIGS. In FIG. 1, a data communication device 10 is connected to a communication line network N in parallel connection with a telephone set 20 so as to be able to respond with the same destination number as shown in FIG. Even when a call is made to the devices 10A to 10C, the telephone set 20 rings the ringing bell by the detected ringing.

For this reason, the host device H sets the number of times of ringing in the RAM for each of the data communication devices 10A to 10C and performs automatic calling, but before the calling of the number of times of ringing ends, the telephone 20 goes off-hook. Is sent from the beginning after sending out the prepared message "Because this is a communication with another device, do not go off-hook (respond) for the next incoming call." The operation has to be redone. Therefore, communication with the data communication device 10 specified by being repeatedly off-hook by the telephone set 20 is not prevented. When a manual call is made by the host device H, the message may be transmitted orally.

The number of times of ringing set in the host device H and the data communication devices 10A to 10C is as large as 12 for the data communication device 10A, 14 for the data communication device 10B, and 16 for the data communication device 10C. Is set, the data communication device 10 or the telephone 20 does not respond to a call from another telephone, so that the telephone is on-hook and ringing is stopped, or the telephone 20 is immediately off-hook Even when ringing stops, it is possible to reduce the risk of erroneously determining that the call is to the own device.

As described above, in the present embodiment, in addition to the operation and effect of the above-described embodiment, it is possible to prevent the telephone 20 from repeatedly going off-hook despite a call to the data communication apparatus 10. Then, the call to the data communication device 10 can be resumed to perform the data communication. In the above-described embodiment, the communication line network is simply described. However, the present invention can be applied to a data communication device or a host device connected to a private premises line or a LAN, or a public communication system such as a PSTN or ISDN. It goes without saying that the present invention may be applied to a data communication device or a host device connected to a line network. Further, the present invention is not limited to the data communication device, and may be applied to other communication devices. For example, the present invention can be applied to a telephone by setting a call receiving period.

[0028]

According to the present invention, even when a plurality of receiving apparatuses are responsively connected to one piece of destination information, the calling apparatus can establish a connection by setting individually different incoming call periods in advance. It is possible to obtain a response of the called device only by terminating the call once during the call receiving period of the desired called device and then calling again. Therefore, it is possible to use a plurality of receiving apparatuses corresponding to one piece of destination information without limitation, and to easily use communication lines with a simple configuration. In addition, by returning to the standby state when the calling device waits a long time for recalling, it is possible to reduce the possibility of erroneously responding to an unrelated incoming call that follows when the call is accidentally completed in the set incoming call period. And the availability can be secured.

Further, by setting a calling period corresponding to the incoming period of the receiving device in the transmitting device in advance, it is only necessary to specify the other party and to issue a calling command. It is possible to easily obtain a response from the terminating device that desires connection by re-calling after the call, thereby ensuring convenience. Also, by sending a predetermined message if there is a response before the call during the calling period ends,
It is possible to prevent a response other than the specified receiving device from repeatedly responding, and to ensure availability.
