Therefore, detailed description thereof will not be repeated here.

  Slave device 104 according to the present embodiment is realized by hardware of slave device 104 and software executed by videophone control unit 184. Generally, such software is stored and distributed in a recording medium such as the memory card 155, read from the recording medium by the memory card driving device 138 or the like, and temporarily stored in the memory 174 or the like. Further, it is executed by the TV phone control unit 184 described above. The above-described hardware of the slave unit 104 is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since the operation of slave unit 104 itself is well known, detailed description thereof will not be repeated here.

  Referring to FIG. 5, the program executed in the communication system executes the following control for incoming calls.

  In step S200, incoming call detection unit 140 determines whether an incoming call has been detected from the public network. As a result, the incoming call detection unit 140 determines whether an incoming call request is received from the PDA 100 based on the information received by the analog interface 110. If it is determined that an incoming call has been detected from the public network (YES in step S200), the process proceeds to step S202. If not (NO in step S200), the process returns to step S200.

  In step S 202, videophone control unit 136 causes data control unit 128 to read out information representing the first communication device in the incoming order table 142 stored in memory 126. When the information is read, the TV phone control unit 136 outputs the information read by the data control unit 128 to the communication control unit 112. The communication control unit 112 controls the analog cordless controller 134 so as to transmit that the incoming call is detected to the communication device represented by the information output from the TV phone control unit 136. That is, the communication control unit 112 notifies an incoming call according to the incoming order table 142. As a result, when the communication control unit 112 receives a request for an incoming call from the PDA 100, the communication control unit 112 receives a request for the incoming call from the PDA 100 to the slave unit 104 according to the information indicating the order of selection stored in the memory 126. Therefore, the analog cordless controller 134 is controlled so as to transmit the information to the effect. When the information output from the videophone control unit 136 represents the parent device 102 itself, the communication control unit 112 notifies the videophone control unit 136 of an incoming call.

  In step S204, at least one of parent device 102 and child device 104 starts ringing. FIG. 6 is a diagram showing signal exchange when PDA 100 requests parent device 102 for an incoming call in the present embodiment. In the case of this embodiment, when there is an incoming call, an activation signal is sent from the public network. The incoming call detection unit 140 detects that an activation signal has been received via the analog interface 110. Thereafter, the incoming call detection unit 140 detects information representing the PDA 100 (sender information). Thereafter, a call signal is sent from the public network. The incoming call detection unit 140 detects a call signal via the analog interface 110. Communication control unit 112 outputs caller information and information indicating that an incoming call request has been received, to TV phone control unit 136. The videophone control unit 136 causes the data control unit 128 to read out information stored in the incoming order table 142. If the base unit 102 needs to receive an incoming call (if the “information indicating the order of selection” read from the memory 126 represents the base unit 102), the videophone control unit 136 transmits the voice through the voice control unit 116. The input / output unit 114 is caused to output a ringing tone. In addition, the TV phone control unit 136 causes the display unit 122 to display the caller number through the display control unit 124. Even when any of the handset devices 104 starts ringing, the communication control unit 112 receives the caller information and the incoming call request among the above-described exchanges in the handset 104 that starts ringing. The same operation as that after the information is output to the TV phone control unit 136 is performed.

  In step S206, the incoming call detection unit 140 refers to the information received by the analog cordless controller 134, and determines whether any of the handset 104 has transmitted information indicating that the incoming call is accepted. At the same time, the TV phone control unit 136 determines whether or not the information indicating that the incoming call is accepted is received based on the content of the operation detected by the operation detection unit 132. As a result, the incoming call detection unit 140 and the videophone control unit 136 determine whether any of the terminals (at least one of the parent device 102 and the child device 104) has responded to the incoming call. If it is determined that any terminal has responded to the incoming call (YES in step S206), the process proceeds to step S208. If not (NO in step S206), the process proceeds to step S212.

  In step S208, the TV phone control unit 136 causes the voice control unit 116 to control the voice input / output unit 114 to stop outputting the ringtone. In addition, the TV phone control unit 136 controls the communication control unit 112 to transmit information indicating that the analog cordless controller 134 stops outputting the ring tone. As a result, the TV phone control unit 136 stops ringing of the ringtone.

  In step S210, the TV phone control unit 136 outputs a signal for instructing the communication control unit 112 to perform a call process. The communication control unit 112 controls the analog interface 110 so as to communicate information necessary for starting a call as a call process. When the terminal that responds to the incoming call is one of the handset 104, the communication control unit 112 controls the analog cordless controller 134 so as to communicate information necessary for starting a call. Thereby, when the analog cordless controller 134 receives information from the slave unit 104 that the incoming call is accepted, the communication control unit 112 communicates with the analog interface 110 and the analog cordless so as to communicate information necessary for starting a call. The controller 134 will be controlled.

  In step S212, incoming call detection unit 140 determines whether or not the call from the public network has ended. In the present embodiment, when a call from the public network is terminated, the call signal from the public network is stopped. The incoming call detection unit 140 determines whether or not the call from the public network has ended by detecting the stop of the call signal via the analog interface 110. As a result, the incoming call detection unit 140 determines whether the PDA 100 has canceled the incoming call request based on the information received by the analog interface 110. If it is determined that the call from the public network has been completed (YES in step S212), the process proceeds to step S214. If not (NO in step S212), the process proceeds to step S206.

  In step S214, communication control unit 112 outputs to TV phone control unit 136 that the call from the public network has ended. When the voice input / output unit 114 of the base unit 102 continues to ring the ringtone, the videophone control unit 136 stops the voice input / output unit 114 from outputting the ringtone to the voice control unit 116. Let me control. The videophone control unit 136 causes the display control unit 124 to control the display unit 122 so as to erase the caller number being displayed. When the handset 104 continues ringing the ring tone, the videophone control unit 136 sends a signal to the communication control unit 112 to instruct the analog cordless controller 134 to stop ringing. Let me control. As a result, the TV phone control unit 136 stops ringing of the ringtone.

  In step S 216, videophone control unit 136 outputs a signal indicating that incoming order table 142 should be updated to data control unit 128. The data control unit 128 updates the information stored in the incoming order table 142, that is, the memory 126. As a result, when the PDA 100 cancels the incoming call request, the data control unit 128 sets at least one communication device set as a transmission destination of information indicating that the incoming call request has been received. The information stored in the memory 126 (the incoming order table 142) is updated so that the set is different from that before canceling the request.

  The operation of the communication system based on the above structure and flowchart will be described.

  The incoming call detection unit 140 determines whether an incoming call is detected from the public network (step S200). While no incoming call is detected from the public network (NO in step S200), incoming call detection unit 140 repeatedly determines whether an incoming call has been detected from the public network. Thereafter, when an incoming call is detected from the public network (YES in step S200), communication control unit 112 communicates the incoming call according to incoming call order table 142 (step S202). Referring to FIG. 3, destinations at the head of the order are base unit 102 and handset 104. Accordingly, the communication control unit 112 notifies the incoming call to the parent device 102 and the child device 104. When the incoming call is notified, base unit 102 and handset 104 start ringing (step S204).

  When ringing is started, the incoming call detection unit 140 determines whether any terminal has responded to the incoming call (step S206). In this case, if no terminal responds to the incoming call (NO in step S206), incoming call detection unit 140 determines whether the call from the public network has ended (step S212). While the call from the public network has not ended (NO in step S212), the processes in steps S206 to S212 are repeated.

  Thereafter, when the call from the public network is completed (YES in step S212), ringing of the ringtone in base unit 102 and handset 104 is stopped (step S214). When the ringing tone stops, the data control unit 128 updates the incoming order table 142 (step S216). In the case of the present embodiment, the data control unit 128 lowers the destinations with the head in the order (in the case of FIG. 3, the base unit 102 and the handset 104) to the end, and the destinations with the second and subsequent orders in sequence. The incoming order table 142 is updated so as to increase. When the incoming order table 142 is updated, the processing from step S200 to step S216 is repeated.

  As described above, the communication system according to the present embodiment receives a request for an incoming call from a PDA which is an arbitrary telephone set, and satisfies a predetermined requirement (in this embodiment, responds to an incoming call). When the PDA cancels the incoming call request, the incoming order table stored in the memory is updated. Thereby, it is possible to realize the identification incoming call regardless of the time of the call for the call from the general-purpose telephone. The caller can request an incoming call to an arbitrary child device by storing in advance the child device to be received next. As a result, it is possible to provide a relay apparatus and a communication system that realizes an identification incoming call regardless of the time of call for a call from a general-purpose telephone.

  As a first modification, base unit 102 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

  In addition, as a second modified example, “arbitrary telephone” replacing PDA 100 is not particularly limited. If it has a function as a telephone, it may communicate with a handset or the like.

  As a third modification, the communication system according to the present embodiment may communicate with a telephone connected to a monitoring system of a security company as an arbitrary telephone. Thereby, the communication system which concerns on this Embodiment can contribute to ensuring safety | security as a part of security system.

Further, it is executed by the TV phone control unit 244 described above. The hardware itself of the base unit 220 described above is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since operation of base unit 220 itself is well known, detailed description thereof will not be repeated here.

  Other hardware configurations are the same as those in the first embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 9, slave unit 222 includes a LAN controller 260, a communication control unit 262, a voice input / output unit 234, a voice control unit 116, a video input unit 236, a video control unit 120, and a display unit. 238, a display control unit 124, a memory 264, a data control unit 128, an operation unit 240, an operation detection unit 132, a TV phone control unit 244, and a memory card drive device 138.

The communication control unit 262 is a device that controls the LAN controller 260. The memory 264 stores information used by the TV phone control unit 244.

  In the control block diagram shown in FIG. 9, the devices shown in FIGS. 2 and 8 are given the same reference numerals. Their functions are the same. Therefore, detailed description thereof will not be repeated here.

  The handset 222 according to the present embodiment is realized by hardware of the handset 222 and software executed by the TV phone control unit 244. Generally, such software is stored and distributed in a recording medium such as the memory card 155, read from the recording medium by the memory card driving device 138 or the like, and temporarily stored in the memory 264 or the like. Further, it is executed by the TV phone control unit 244 described above. The above-described hardware of the slave unit 222 is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since the operation of handset 222 itself is well known, detailed description thereof will not be repeated here.

  Referring to FIG. 11, the program executed in the communication system executes the following control for incoming calls.

  In step S300, incoming call detection unit 250 determines whether an incoming call has been detected from the Internet network or the like. The first LAN controller 230 constantly monitors the data flowing through the Internet network, and passes the data addressed to the parent device 220 to the incoming call detection unit 250. The incoming call detection unit 250 determines whether an incoming call request is received from the PDA 210 based on the information received by the first LAN controller 230. In addition, the caller detection unit 150 detects information representing the PDA 210 based on the information received by the first LAN controller 230. If it is determined that an incoming call has been detected from the Internet network (YES in step S300), the process proceeds to step S302. If not (NO in step S300), the process returns to step S300.

  In step S <b> 302, videophone control unit 244 causes data control unit 128 to read out information representing the first communication device in the incoming order table 142 stored in memory 126. When information representing the first communication device in the order is read, data control unit 128 outputs the information read by itself to videophone control unit 244. The TV phone control unit 244 outputs the information output from the data control unit 128 to the communication control unit 232. The communication control unit 232 controls the second LAN controller 242 to transmit information indicating that there is an incoming call to the handset 222 indicated by the information output from the TV phone control unit 244. Information for identifying the slave unit 222 by the second LAN controller 242 (in this embodiment, the information for identifying the slave unit 222 is a unique identifier shown in FIG. 3. Instead, a MAC address or IP address unique to the communication system according to the present embodiment may be used.) And information indicating that there is an incoming call is transmitted, so that the handset 222 receives an incoming call. It is possible to detect that information indicating that there was a problem. As a result, when the communication control unit 232 receives an incoming call request from the PDA 210, the information stored in the memory 126 (information indicating that the incoming call request has been received when the incoming call request is received from the PDA 210). The second LAN controller 242 is controlled to transmit information indicating that the incoming call request has been received from the PDA 210 to the handset 222 in accordance with the information indicating the transmission destination).

  In step S304, when the information output from data control unit 128 in step S302 includes information representing base unit 220, videophone control unit 244 receives a ring tone from voice input / output unit 234 through voice control unit 116. Is output. The LAN controller 260 of the handset 222 that has received the information indicating that the incoming call request has been received from the second LAN controller 242 outputs the received information to the communication control unit 262. Communication control unit 262 of handset 222 outputs information received by LAN controller 260 to videophone control unit 244. The TV phone control unit 244 causes the voice input / output unit 234 to output a ring tone through the voice control unit 116. As a result, ringing of the incoming ring tone is started in at least one of the parent device 220 and the child device 222. In step S306, videophone control unit 244 of base unit 220 causes timer 246 to start measuring the length of time.

  In step S308, the TV phone control unit 244 of the parent device 220 determines one of the terminals (the parent device 220 and the child device) based on at least one of the operation detected by the operation detection unit 132 and the information received by the second LAN controller 242. It is determined whether at least one of 222 responds to the incoming call. If it is determined that the incoming call has been answered (YES in step S308), the process proceeds to step S310. If not (NO in step S308), the process proceeds to step S314.

  In step S310, when the voice input / output unit 234 of the parent device 220 outputs a ring tone, the videophone control unit 244 of the base unit 220 receives the ring tone by the voice input / output unit 234 via the voice control unit 116. Stop ringing. At the same time, the TV phone control unit 244 of the base unit 220 outputs a signal to the communication control unit 232 to stop ringing. The communication control unit 232 of the parent device 220 causes the second LAN controller 242 to transmit information indicating that ringing should be stopped. As a result, ringing of the ringtone stops.

  In step S312, communication control unit 232 of base unit 220 causes first LAN controller 230 to communicate information necessary for starting a call. When the second LAN controller 242 receives information indicating that it accepts an incoming call from the handset 222, the communication control unit 232 causes the second LAN controller 242 to communicate information necessary for starting communication. As a result, when the second LAN controller 242 receives information indicating that the incoming call is accepted from the handset 222, the communication control unit 232 communicates information necessary for starting a call so that the first LAN controller 230 and The second LAN controller 242 will be controlled.

  In step S314, incoming call detection unit 250 of base unit 220 determines whether the call from the Internet network or the like has ended. When the PDA 210 cancels the call, the PDA 210 transmits information to cancel the incoming call request via the Internet network or the like. The incoming call detection unit 250 of the parent device 220 determines whether or not the call from the Internet network is finished depending on whether or not the first LAN controller 230 detects a signal indicating that the incoming call request is canceled. As a result, the incoming call detection unit 250 determines whether the PDA 210 has canceled the incoming call request based on the information received by the first LAN controller 230. If it is determined that the call from the Internet network or the like has been completed (YES in step S314), the process proceeds to step S316. If not (NO in step S314), the process proceeds to step S308. In step S316, the terminal that has output the ring tone out of parent device 220 and child device 222 stops ringing by the same operation as in step S310.

  In step S318, videophone control unit 244 of base unit 220 determines whether or not the time measured by timer 246 is less than a predetermined time which is a predetermined period (predetermined period). If it is determined that the time is less than the specified time (YES in step S318), the process proceeds to step S320. If not (NO in step S318), the process proceeds to step S300.

  In step S320, data control unit 128 of base unit 220 updates the contents of incoming order table 142 stored in memory 126. In the case of the present embodiment, the data control unit 128, in the information included in the incoming order table 142, the terminal having the first order is the last, and the terminal having the second and subsequent orders is sequentially repeated. The contents of the incoming order table 142 are updated so as to increase. As a result, when the PDA 210 cancels the incoming call request, the data control unit 128 sets at least one set of communication devices to which the information indicating that the incoming call request has been received, The incoming order table 142, which is information stored in the memory 126, is updated so that the set is different from that before the request is canceled.

  The operation of the communication system based on the above operation and flowchart will be described.

  The incoming call detection unit 250 of the parent device 220 determines whether an incoming call is detected from the Internet network or the like (step S300). If there is an incoming call from PDA 210 (YES in step S300), communication control unit 232 of base unit 220 notifies handset 222 of the incoming call according to incoming order table 142 (step S302). When the incoming call is notified, handset 222 notified of the incoming call starts ringing (step S304).

  When ringing starts, timer 246 of base unit 220 starts measuring the length of time (step S306). When the measurement is started, the TV phone control unit 244 of the parent device 220 determines whether any terminal has responded to the incoming call (step S308). In this case, if none of the terminals responds to the incoming call (NO in step S308), incoming call detection unit 250 determines whether the call from the Internet network or the like has ended (step S314). When the call from the Internet network is completed (YES in step S314), handset 222 that has output the ringtone stops ringing (step S316).

  When the ringing stops, the videophone control unit 244 of the base unit 220 determines whether or not the time measured by the timer 246 is less than the specified time (step S318). In this case, if the time measured by timer 246 is less than the specified time (YES in step S318), data control unit 128 of base unit 220 updates incoming order table 142 stored in memory 126 (step S320). As a result, the data control unit 128 of the base unit 220 stores information stored in the memory 126 when the PDA 210 cancels the incoming call request before a predetermined period of time (“specified time” in the present embodiment) elapses. The incoming order table 142 is updated.

  As described above, since the base unit according to the present embodiment uses only incoming calls less than a certain time for updating the incoming order table, the incoming order table is updated when the incoming order table is not requested to be updated. You can avoid that. For example, when the number of ringing sounds is 1 to 2 times, the incoming order table is updated, and when the ringing sound is 5 to 10 times or more, the incoming order table is not updated. It is. As a result, it is possible to switch the terminal that will receive the next call by making a call from the caller and canceling the call before the callee answers. The caller side can also make an incoming call to the target handset by grasping the order of the incoming order table in advance. As a result, it is possible to provide a relay device and a communication system capable of realizing an identification incoming call regardless of the time of call for a call from a general-purpose telephone.

  As a first modification, base unit 220 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

  As a second modification, in step S320, the data control unit 128 of the base unit 220 may update the contents of the incoming order table 142 according to a predetermined rule. An example of the “predetermined rule” includes associating the contents of the updated incoming order table 142 with the number of times that the ringtone has been played. As a result, if the PDA 210 cancels the incoming call request before the predetermined period elapses, the data control unit 128 receives at least one communication device as a transmission destination of information indicating that the incoming call request has been received. Thus, the incoming order table 142, which is information stored in the memory 126, is updated so that the pair is different from that before the PDA 210 cancels the incoming call request.

<Third Embodiment>
Hereinafter, a relay device and a communication system according to the third embodiment of the present invention will be described.

  The hardware configuration of the communication system according to the present embodiment is the same as that of the second embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 12, the program executed in the communication system performs the following control for incoming calls. In the flowchart shown in FIG. 12, the processes shown in FIG. 11 are given the same step numbers. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S322, videophone control unit 244 of base unit 220 determines whether or not the time measured by timer 246 is equal to or longer than the specified time. If it is determined that the time is longer than the specified time (YES in step S322), the process proceeds to step S320. If not (NO in step S322), the process proceeds to step S300.

  The operation of the communication system based on the above structure and flowchart will be described.

  When the handset 222 that has ringed the ringtone stops ringing (step S316), the videophone control unit 244 of the base unit 220 determines whether or not the time measured by the timer 246 is equal to or longer than the specified time (step S322). ). In this case, if the time measured by timer 246 is equal to or longer than the prescribed time (YES in step S322), data control unit 128 of base unit 220 updates the contents of incoming order table 142 stored in memory 126. (Step S320). As a result, the data control unit 128 of the base unit 220 stores the memory 126 when the PDA 210 cancels the incoming call request after the period during which the incoming call request is received from the PDA 210 exceeds a predetermined length. The incoming order table 142, which is information, is updated.

  As described above, the relay apparatus according to the present embodiment updates the incoming order table only when an incoming call is received for a certain period of time or longer. The incoming order table can be avoided from being updated with respect to (incoming calls made 10 times), and for example, the incoming order table can be updated when the ringtone sounds 15 to 20 times. As a result, it is possible to provide a relay device, a communication system, a relay program, and a computer-readable recording medium on which the relay program can be recorded, which can realize an identification incoming call regardless of the time of the call for a call from a general-purpose telephone. Can do.

<Fourth embodiment>
Hereinafter, a relay device and a communication system according to the fourth embodiment of the present invention will be described.

  Referring to FIG. 13, the communication system according to the present embodiment includes a parent device 224 and a plurality (three in this embodiment) of child devices 222. The base unit 224 is a relay device that relays a call between the PDA 210 as an arbitrary telephone and the handset 222. Base unit 224 is also a device that communicates with PDA 210 by itself.

  Referring to FIG. 14, base unit 224 includes first LAN controller 230, communication control unit 232, audio input / output unit 234, audio control unit 116, video input unit 236, video control unit 120, and display. Unit 238, display control unit 124, memory 126, data control unit 128, operation unit 240, operation detection unit 132, second LAN controller 242, videophone control unit 244, counter 248, memory card Drive device 138. The counter 248 is a counting device that counts the number so that the value increases by a certain value (in this embodiment, “1”) every time a predetermined unit time elapses.

  In the control block diagram shown in FIG. 14, the devices shown in FIGS. 2 and 8 are given the same reference numerals. Their functions are the same. Therefore, detailed description thereof will not be repeated here.

  Base unit 224 according to the present embodiment is realized by hardware of base unit 224 and software executed by videophone control unit 244. Generally, such software is stored and distributed in a recording medium such as the memory card 155, read from the recording medium by the memory card driving device 138 or the like, and temporarily stored in the memory 126 or the like. Further, it is executed by the TV phone control unit 244 described above. The hardware itself of the parent device 224 described above is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as a memory card. Since the operation of base unit 224 is well known, detailed description thereof will not be repeated here.

  Other hardware configurations are the same as those in the second embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 15, the program executed in the communication system executes the following control for incoming calls. In the flowchart shown in FIG. 15, the processes shown in FIG. 11 are given the same step numbers. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S330, TV phone control unit 244 of base unit 224 causes counter 248 to start counting.

  In step S332, videophone control unit 244 of base unit 224 determines whether or not the number counted by counter 248 is less than a predetermined number that is a predetermined number. If it is determined that the number is less than the prescribed number (YES in step S332), the process proceeds to step S320. If not (NO in step S332), the process proceeds to step S300.

  The operation of the communication system based on the above structure and flowchart will be described.

  When ringing is started, the counter 248 starts counting (step S330). When the counting is started, through the processing of step S308 to step S316, the TV phone control unit 244 of the base unit 224 determines whether or not the number counted by the counter 248 is less than the specified number (step S332). In this case, if the number counted by counter 248 is less than the prescribed number (YES in step S332), data control unit 128 of base unit 224 updates incoming order table 142, which is information stored in memory 126 (step S320). As a result, the data control unit 128 of the base unit 224 has a period of a length obtained by multiplying a predetermined unit time (in the present embodiment, a time equal to the ringing tone ringing period in the base unit 224) by a predetermined integer. If the PDA 210 cancels the incoming call request before elapses, the incoming order table 142, which is information stored in the memory 126, is updated.

  As described above, since the communication system according to the present embodiment uses only less than a certain number of incoming calls for updating the incoming call order table, the incoming call order table for normal incoming calls that do not require the incoming call order table to be updated. Can avoid being updated. For example, in the case of a normal incoming call, if the ring tone rings 5 to 10 times, the incoming order table can be updated only when the ring tone rings about 1 to 2 times. Thereby, it is possible to realize the identification incoming call regardless of the time of the call for the call from the general-purpose telephone. As a result, it is possible to provide a relay device, a communication system, a relay program, and a computer-readable recording medium on which the relay program can be recorded, which can realize an identification incoming call regardless of the time of the call for a call from a general-purpose telephone. Can do.

  As a first modification, the counter 248 may be a counting device that counts the number so that the value increases by a certain value every time a signal indicating that a ringing tone has been generated from the handset 222 is received. . Also in this case, since the ringing tone ringing period in the handset 222 is constant, the counter 248 is a counting device that counts the number so that the value increases by a constant value every time a predetermined unit time elapses.

  As a second modification, base unit 224 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

<Fifth embodiment>
Hereinafter, a relay device and a communication system according to the fifth embodiment of the present invention will be described.

  The hardware configuration of the communication system according to the present embodiment is the same as that of the above-described fourth embodiment. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 16, the program executed in the communication system executes the following control for incoming calls. In the flowchart shown in FIG. 16, the processes shown in FIGS. 11 and 15 are given the same step numbers. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S340, videophone control unit 244 of base unit 224 determines whether the number counted by counter 248 is equal to or greater than the specified number. If it is determined that the number of times has been exceeded (YES in step S340), the process proceeds to step S320. If not (NO in step S340), the process proceeds to step S300.

  The operation of the communication system based on the above structure and flowchart will be described.

  When ringing of the ringtone stops, the TV phone control unit 244 of the base unit 224 determines whether or not the number counted by the counter 248 is equal to or greater than the specified number (step S340). If it is determined that the number counted by counter 248 is equal to or greater than the prescribed number (YES in step S340), data control unit 128 of base unit 224 updates incoming order table 142 (step S320). As a result, the data control unit 128 of the base unit 224 has a period during which the incoming call request is received from the PDA 210 is equal to a predetermined unit time (in this embodiment, the ringing tone ringing time in the base unit 224). When the PDA 210 cancels the incoming call request after a period of a length obtained by multiplying the predetermined time by a predetermined integer, the memory 126 stores and updates the incoming order table 142, which is information indicating the selection order. Will be.

  As described above, the communication system according to the present embodiment updates the incoming order table only when an incoming call is received a certain number of times or more. As a result, it is possible to avoid updating the incoming call order table for normal incoming calls. For example, in the case of a normal incoming call, if the ring tone sounds 5 to 10 times, the incoming order table can be updated only when the ring tone sounds 15 to 20 times. As a result, it is possible to provide a relay device, a communication system, a relay program, and a computer-readable recording medium on which the relay program can be recorded, which can realize an identification incoming call regardless of the time of the call for a call from a general-purpose telephone. Can do.

  As a modification, the counter 248 may be a counting device that counts the number so that the value increases by a certain value each time a signal indicating that a ring tone has been generated from the handset 222 is received. Also in this case, since the ringing tone ringing period in the handset 222 is constant, the counter 248 is a counting device that counts the number so that the value increases by a constant value every time a predetermined unit time elapses.

Therefore, detailed description thereof will not be repeated here.

  Router 350 according to the present embodiment is realized by hardware of router 350 and software executed by main control unit 408. Generally, such software is stored and distributed in a recording medium such as the memory card 155, read from the recording medium by the memory card driving device 138 or the like, and temporarily stored in the memory 404 or the like. Further, it is executed by the main control unit 408 described above. The hardware of the router 350 described above is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since operation of router 350 itself is well known, detailed description thereof will not be repeated here.

  Referring to FIG. 19, slave unit 352 includes a LAN controller 412, a communication control unit 262, a voice input / output unit 234, a voice control unit 116, a video input unit 236, a video control unit 120, and a display unit. 238, a display control unit 124, a memory 264, a data control unit 128, an operation unit 240, an operation detection unit 132, a TV phone control unit 244, and a memory card drive device 138. The LAN controller 412 is a device that communicates with the router 350. In the control block diagram shown in FIG. 19, the devices shown in FIG. 9 are given the same step numbers. These processes are the same. Therefore, detailed description thereof will not be repeated.

  Other hardware configurations are the same as those in the second embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 20, the program executed in the communication system has the following control structure for incoming calls.

  In the flowchart shown in FIG. 20, the same step numbers are assigned to the processes shown in FIG. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S418, timer 410 measures the passage of time since the power was turned on.

  In step S420, main control unit 408 of router 350 determines whether or not the time measured by timer 410 exceeds a predetermined time (threshold). If it is determined that the predetermined time has passed (YES in step S420), the process proceeds to step S422. Otherwise (NO in step S420), the process proceeds to step S424. In step S422, the data control unit 406 of the router 350 updates the incoming order table 142 stored in the memory 404 to an initial state that is a predetermined state.

  In step S424, first LAN controller 230 communicates with PDA 210, which is an arbitrary telephone. The incoming call detection unit 250 determines whether an incoming call request is received from the PDA 210 based on the information received by the first LAN controller 230. Thus, it is determined whether or not an incoming call is detected from the Internet network or the like. If it is determined that an incoming call has been detected (YES in step S424), the process proceeds to step S428. If not (NO in step S424), the process proceeds to step S420.

  In step S428, data control unit 406 of router 350 reads information representing slave unit 352 having the head in the order from incoming order table 142 stored in memory 404. When the information is read, data control unit 406 outputs the read information to main control unit 408. The main control unit 408 outputs the information read by the data control unit 406 to the communication control unit 232. The communication control unit 232 controls the second LAN controller 242 to transmit information indicating that the incoming call request has been received from the PDA 210 to the child device 352 represented by the information output from the main control unit 408. That is, the communication control unit 232 notifies the incoming call according to the incoming call order table 142. As a result, the communication control unit 232 receives the incoming call request from the PDA 210, and stores the information stored in the memory 404 and included in the incoming order table 142 (the incoming call request when the incoming call request is received from the PDA 210). The second LAN controller 242 is controlled to transmit information indicating that the incoming call request is received from the PDA 210 to the slave unit 352 in accordance with the information indicating the transmission destination of the information indicating that the request is received. Will be.

  In step S430, the communication control unit 232 of the router 350 refers to the information received by the second LAN controller 242 to determine whether any of the slave units 352 has responded to the incoming call. If it is determined that the incoming call has been answered (YES in step S430), the process proceeds to step S432. Otherwise (NO in step S430), the process proceeds to step S436.

  In step S432, main control unit 408 of router 350 outputs a signal to communication control unit 232 to stop ringing. The communication control unit 232 controls the second LAN controller 242 so as to transmit to the handset 352 information indicating that ringing should be stopped. Thereby, handset 352 stops ringing.

  In step S434, the communication control unit 232 controls the first LAN controller 230 so that the first LAN controller 230 communicates information necessary for starting a call to the PDA 210. The communication control unit 232 of the router 350 controls the second LAN controller 242 so as to communicate information necessary for starting a call to the handset 352 that has transmitted information indicating that the incoming call is accepted. As a result, when the second LAN controller 242 receives information indicating that the incoming call is accepted from the slave unit 352, the communication control unit 232 of the router 350 communicates the information necessary for starting the call. The controller 230 and the second LAN controller 242 are controlled.

  In step S436, the incoming call detection unit 250 of the router 350 determines whether or not the call from the Internet network has ended based on whether or not the first LAN controller 230 has received information indicating that the incoming call request has been canceled. Determine whether. As a result, the incoming call detection unit 250 determines whether the PDA 210 has canceled the incoming call request based on the information received by the first LAN controller 230. If it is determined that the call has ended (YES in step S436), the process proceeds to step S438. If not (NO in step S436), the process proceeds to step S430.

  In step S437, the main control unit 408 of the router 350 causes the timer 410 to start measuring time from the time when it is determined in step S436 that the call from the Internet network or the like has ended. As a result, the timer 410 measures the passage of time until it starts to receive a request for an incoming call from the PDA 210 (which may be a telephone other than the PDA 210).

  In step S438, communication control unit 232 of router 350 controls second LAN controller 242 to transmit information indicating that ringing is stopped. Thereby, handset 352 stops ringing.

  In step S440, data control unit 406 of router 350 updates the contents of incoming order table 142 stored in memory 404. As a result, the data control unit 406 determines that the set of at least one communication device that is the transmission destination of the information indicating that the incoming call request has been received is different from the set before the PDA 210 cancels the incoming call request. Thus, the incoming order table 142, which is information stored in the memory 404, is updated.

  The operation of the communication system based on the above structure and flowchart will be described.

  The timer 410 measures the passage of time from when the power is turned on (step S418). When the passage of time is measured, the main control unit 408 of the router 350 determines whether or not the time measured by the timer 410 exceeds a certain time (step S420). In this case, if the time measured by timer 410 exceeds a certain time (YES in step S420), data control unit 406 updates incoming order table 142 stored in memory 404 to an initial state (step S422). . As a result, when the time from when the power is turned on exceeds the threshold, the data control unit 406 stores the memory 404 so that the destination of the information indicating that the incoming call request has been received is the predetermined slave unit 352. The information stored in the incoming order table 142 is changed. When the incoming order table 142 is updated, the communication control unit 232 of the router 350 determines whether an incoming call is detected from the Internet network (step S424). In this case, if an incoming call is detected (YES in step S424), communication control unit 232 of router 350 notifies handset 352 of the incoming call in accordance with incoming order table 142 stored in memory 404 (step S428). When the incoming call is notified, the communication control unit 232 of the router 350 determines whether any of the slave units 352 responds to the incoming call through the process of step S304 (step S430). In this case, if none of the slave units 352 responds to the incoming call (NO in step S430), incoming call detection unit 250 of router 350 determines whether or not the call from the Internet network has ended (step S436). ). Initially, the call has not ended (NO in step S436), but after the processing of step S430 and step S436 is repeated and then the call is ended (YES in step S436), timer 410 of router 350 is connected to the Internet. Time measurement is started from the time when it is determined that the call from the network is completed (step S437). As a result, the timer 410 measures the passage of time since the PDA 210 canceled the incoming call request. When time measurement is started, handset 352 stops ringing (step S438). When ringing is stopped, the data control unit 406 of the router 350 updates the contents of the incoming order table 142, which is information stored in the memory 404 (step S440).

  When the contents of the incoming order table 142 are updated, the main control unit 408 of the router 350 determines whether or not the time measured by the timer 410 exceeds a certain time (step S420). In this case, since it is considered that the time measured by timer 410 does not exceed a certain time (NO in step S420), communication control unit 232 of router 350 determines whether an incoming call has been detected from the Internet network. (Step S424). In this case, if there is no incoming call (NO in step S420), the processes in steps S420 to S424 are repeated. Thereafter, when the time measured by timer 410 exceeds a certain time (YES in step S420), data control unit 406 updates incoming order table 142 stored in memory 404 to an initial state (step S422). As a result, when the time from when the PDA 210 cancels the incoming call request exceeds the threshold, the data control unit 406 sets the transmission destination of the information indicating that the incoming call request is received to the predetermined slave unit 352. As described above, the information stored in the incoming order table 142 of the memory 404 is changed.

  As described above, the communication system according to the present embodiment returns the incoming call order table to the initial state when there is no incoming call for a certain period of time. Since the incoming order table is returned to the initial state, it is easy to grasp the next destination from the calling side. As a result, a relay device, a communication system, a relay program, and a computer on which a relay program can be recorded that can realize an identification incoming call for a call from a general-purpose telephone regardless of the time of the call and can easily specify the destination A readable recording medium can be provided.

  As a first modification, instead of causing timer 410 to start measuring time in step S437, if it is determined in step S424 that an incoming call has been detected from the Internet network (YES in step S424). Time measurement may be started. In this case, the timer 410 measures the passage of time since the PDA 210 started the incoming call request.

  As a second modification, any of the handset 352 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

Further, it is executed by the TV phone control unit 244 described above. The hardware itself of the master unit 452 described above is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since operation of base unit 452 itself is well known, detailed description thereof will not be repeated here.

  Referring to FIG. 23, handset 454 includes a LAN controller 260, a communication control unit 262, a voice input / output unit 234, a voice control unit 116, a video input unit 236, a video control unit 120, and a display unit. 238, a display control unit 124, a memory 126, a data control unit 128, an operation unit 240, an operation detection unit 132, a TV phone control unit 244, and a memory card 138. In the flowchart shown in FIG. 23, the devices shown in FIGS. 8 and 9 are given the same reference numerals. Their functions are the same. Therefore, detailed description thereof will not be repeated here.

  Slave unit 454 according to the present embodiment is realized by hardware of slave unit 454 and software executed by videophone control unit 244. Generally, such software is stored and distributed in a recording medium such as the memory card 155, read from the recording medium by the memory card driving device 138 or the like, and temporarily stored in the memory 126 or the like. Further, it is executed by the TV phone control unit 244 described above. The above-described hardware of the slave unit 454 is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since the operation of slave unit 454 is well known, detailed description thereof will not be repeated here.

  Referring to FIG. 24, the program executed in the control system executes the following control for incoming calls. In the flowchart shown in FIG. 24, the processing shown in FIG. 11 is given the same step number. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S460, incoming call detection unit 250 of base unit 452 determines whether an incoming call is detected from the Internet network or the like. The LAN controller 455 constantly monitors data flowing through the Internet network and the like, and passes data addressed to the parent device 452 to the incoming call detection unit 250. The incoming call detection unit 250 determines whether an incoming call request is received from the PDA 210 based on the information received by the LAN controller 455. In addition, the caller detection unit 150 detects information representing the PDA 210 based on the information received by the LAN controller 455. If it is determined that an incoming call is detected from the Internet or the like (YES in step S460), the process proceeds to step S461. If not (NO in step S460), the process returns to step S460.

  In step S461, videophone control unit 244 of base unit 452 causes data control unit 128 to read the contents of incoming order table 142 stored in memory 126. When the contents of the incoming order table 142 are read, the data control unit 128 outputs the read data itself to the TV phone control unit 244. The TV phone control unit 244 outputs the data output from the data control unit 128 to the communication control unit 232. Communication control unit 232 controls LAN controller 455 to transmit information indicating that there is an incoming call to slave unit 454 represented by the data output from TV phone control unit 244. Information for identifying the slave unit 454 by the LAN controller 455 (in this embodiment, the information for identifying the slave unit 454 is a unique identifier shown in FIG. 3. Instead of the identification ID) In addition, since the information indicating that there was an incoming call may be transmitted together with the communication system according to the present embodiment, a unique MAC address or IP address may be used. It can be detected that the information to the effect has been transmitted. As a result, when the communication control unit 232 of the base unit 452 receives a call request from the PDA 210, the information stored in the memory 126 and included in the incoming order table 142 (when a call request is received from the PDA 210) Information indicating that a request for an incoming call is received from the PDA 210 to the slave unit 454 in accordance with the information indicating that the request for the incoming call is received. Thus, the LAN controller 455 is controlled.

  In step S462, communication control unit 232 of base unit 452 causes LAN controller 455 to communicate information necessary for starting a call. When the LAN controller 455 receives information indicating that it accepts an incoming call from the slave unit 454, the communication control unit 232 controls the LAN controller 455 to communicate information necessary for starting communication. As a result, when the LAN controller 455 receives the information indicating that the incoming call is accepted from the slave unit 454, the communication control unit 232 controls the LAN controller 455 so as to communicate information necessary for starting a call. It will be. The communication control unit 232 of the parent device 452 controls the LAN controller 455 so as to communicate information necessary for starting communication even when the user operates the operation unit 240 of the parent device 452.

  In step S463, incoming call detection unit 250 of base unit 452 determines whether the call from the Internet network or the like has ended. When the PDA 210 cancels the call, the PDA 210 transmits information to cancel the incoming call request via the Internet network or the like. The incoming call detection unit 250 of the base unit 452 determines whether or not the call from the Internet network has been completed, depending on whether or not a signal for canceling the incoming call request is detected. As a result, the incoming call detection unit 250 determines whether the PDA 210 has canceled the incoming call request based on the information received by the LAN controller 455. If it is determined that the call from the Internet network or the like has been completed (YES in step S463), the process proceeds to step S316. If not (NO in step S463), the process proceeds to step S308.

  In step S464, caller detection unit 150 of base unit 452 determines whether or not the caller information received by LAN controller 260 is the caller information of the caller set in advance. If it is determined that the caller information is a preset sender (YES in step S464), the process proceeds to step S465. If not (NO in step S464), the process proceeds to step S460.

  In step S465, data control unit 128 of base unit 452 updates the contents of incoming order table 142 stored in memory 126. In the case of the present embodiment, the data control unit 128, in the information included in the incoming order table 142, the terminal having the first order is the last, and the terminal having the second and subsequent orders is sequentially repeated. The contents of the incoming order table 142 are updated so as to increase. As a result, the data control unit 128 determines that the set of at least one communication device that is the transmission destination of the information indicating that the incoming call request has been received is different from the set before the PDA 210 cancels the incoming call request. Thus, the incoming order table 142, which is information stored in the memory 126, is updated.

  The operation of the communication system based on the above structure and flowchart will be described.

  The incoming call detection unit 250 determines whether an incoming call is detected from the Internet network or the like (step S460). When an incoming call is detected from the Internet network or the like (YES in step S460), communication control unit 232 transmits information indicating that there was an incoming call to slave unit 454 represented by the data output from TV phone control unit 244. The LAN controller 455 is controlled (step S461). When the information is transmitted, through the processing of step S304 to step S308, the incoming call detection unit 250 of the parent device 452 determines whether or not the call from the Internet network or the like is finished (step S463). Initially, the call from the Internet network or the like does not end (NO in step S463), and therefore the processing in steps S308 to S463 is repeated. Thereafter, since the call from the Internet network or the like is terminated (YES in step S463), the caller information received by LAN controller 260 is set in advance by caller detection unit 150 of base unit 452 through the process of step S316. It is determined whether or not the caller information of the caller who made the call (step S464). In this case, if the caller information received by LAN controller 260 is the caller information of the caller set in advance (YES in step S464), data control unit 128 of base unit 452 receives the incoming order table stored in memory 126. The contents of 142 are updated (step S465). As a result, when the PDA 210 that is a predetermined telephone cancels the incoming call request, the data control unit 128 of the main unit 452 receives at least one communication device that is a transmission destination of information indicating that the incoming call request has been received. Thus, the incoming order table 142, which is information stored in the memory 126, is updated so that the pair is different from that before the PDA 210 cancels the incoming call request.

  As described above, the communication system according to the present embodiment can prohibit a third party from updating the incoming call order table by setting in advance a transmission source that can perform an identification incoming call. Accordingly, a relay device, a communication system, a relay program, and the like, which can realize identification incoming call regardless of the time of call for a call from a general-purpose telephone, and can be controlled so that a third party cannot perform identification incoming call, A computer-readable recording medium on which the relay program is recorded can be provided.

  As a first modification, instead of determining whether or not the caller information of the caller is set in advance in step S464, the caller detection unit 150 sets the caller information other than the caller set in advance. It may be determined whether or not. In this case, the data control unit 128 of the base unit 452 satisfies the predetermined requirement of being a caller other than a preset caller, and when the PDA 210 cancels the incoming call request, the incoming order table 142 which is information stored in the memory 126 is stored. It will be updated.

  Further, as a second modification, base unit 452 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

  As a third modification, the communication control unit 232 of the parent device 452 should update the content of the incoming order table 142 after the data control unit 128 updates the content of the incoming order table 142 in step S465. The LAN controller 260 may be controlled to transmit information to that effect. When the information indicating that the content of the incoming order table 142 should be updated is transmitted, the data control unit 128 of each of the slave units 454 has the terminal in the order of the incoming order as the last, and the order is the second or later. The contents of the incoming call order table 142 are updated so that the order of the terminals that have been increased sequentially. When the data control unit 128 of each slave unit 454 updates the contents of the incoming order table 142, the data control unit 128 of each slave unit 454 updates the incoming order table 142 of each slave unit 454 so that the contents match. There is a need to. Thereby, each handset 454 can determine whether or not to ring the incoming call sound by referring to the contents of its own incoming call order table 142.

  As a fourth modification, caller detection unit 150 of base unit 452 determines whether or not the caller information received from PDA 210 represents an incoming call from a caller set in advance, and videophone control unit 244 is set. However, it is determined whether or not the elapsed time from the incoming call measured by the timer 246 exceeds the set value, and when the time measured by the timer 246 exceeds the set value, the communication control unit 232 transmits information, You may make the subunit | mobile_unit 454 start ringing of a ringtone. As a result, the communication control unit 232 of the base unit 452 receives a request for an incoming call from the PDA 210 that is a predetermined telephone, and when a predetermined period elapses, the communication control unit 232 In this case, the LAN controller 455 is controlled to transmit information indicating that the incoming call request is received from the PDA 210 to the slave unit 454).

  Base unit 510 according to the present embodiment is realized by hardware of base unit 510 and software executed by videophone control unit 136. Generally, such software is stored and distributed in a recording medium such as the memory card 155, read from the recording medium by the memory card driving device 138 or the like, and temporarily stored in the memory 126 or the like. Further, it is executed by the TV phone control unit 136 described above. The hardware itself of base unit 510 described above is general. Therefore, the most essential part of the present invention is a program recorded on a recording medium such as the memory card 155. Since the operation of base unit 510 itself is well known, detailed description thereof will not be repeated here.

  Other hardware configurations are the same as those in the first embodiment described above. Their functions are the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 27, the program executed in the communication system performs the following control for incoming calls. In the flowchart shown in FIG. 27, the process shown in FIG. 5 is given the same step number. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S530, caller detection unit 150 of base unit 510 determines whether there is an incoming call from a line for updating incoming order table 142. In the present embodiment, it is assumed that the public network of the telephone company A is a line that updates the incoming order table 142. As a result, the caller detection unit 150 of the base unit 510 receives an incoming call for the telephone number of the telephone company A, which is a predetermined telephone number among the plurality of telephone numbers, from the PDA 100 based on the information received by the communication block described above. It is determined whether or not the request is received. If it is determined that there is an incoming call from the line for updating incoming order table 142 (YES in step S530), the process proceeds to step S202. If not (NO in step S530), the process proceeds to step S531.

  In step S531, videophone control unit 136 of base unit 510 reads data representing the base unit 510 and all the slave units 104 from incoming order table 142 stored in memory 126 to data control unit 128. Let When the information is read, the TV phone control unit 136 outputs the information read by the data control unit 128 to the communication control unit 112. The communication control unit 112 controls the analog cordless controller 134 so as to transmit that the incoming call has been detected to the parent device 510 and all the child devices 104. When the information output from the TV phone control unit 136 represents the parent device 510 itself, the communication control unit 112 notifies the TV phone control unit 136 of an incoming call.

  In step S534, caller detection unit 150 of base unit 510 updates the incoming order table 142 (as described above, in this embodiment, the telephone network A's public network is included in incoming order table 142). It is determined whether there is an incoming call from the line to be updated. If it is determined that there is an incoming call (YES in step S534), the process proceeds to step S216. Otherwise (NO in step S534), the process proceeds to step S200.

  An operation of the communication system based on the above structure and flowchart will be described.

  After determining that incoming call detection unit 140 has detected an incoming call from the public network (YES in step S200), caller detection unit 150 determines whether the incoming call is from a line for which incoming order table 142 is to be updated. (Step S530). In this case, if the incoming call comes from the telephone company A, which is the line for updating incoming call order table 142 (YES in step S530), communication control unit 112 follows incoming call order table 142. An incoming call is notified to the slave unit 104 (step S202). When the incoming call is notified, the caller detection unit 150 of the base unit 510 determines whether or not there is an incoming call from the line for updating the incoming call order table 142 through the processing of step S204 to step S214 (step S534). ). If there is an incoming call (YES in step S534), data control unit 128 of base unit 510 updates incoming order table 142 (step S216). As a result, before the analog cordless controller 134 receives information indicating that the analog cordless controller 134 accepts an incoming call from the slave unit 104, the data control unit 128 receives an incoming call for a predetermined telephone number (A telephone company's telephone number). When the call request is canceled, the incoming order table 142, which is information stored in the memory 126, is updated.

  As described above, the relay device, the communication system, the relay program, and the computer-readable recording medium that records the relay program according to the present embodiment can be used at the time of call for a call from a general-purpose telephone. Regardless of this, it is possible to realize the identification incoming call, and it is possible to prevent an unexpected identification incoming call from being implemented by an incoming call from a third party.

  As a modification, base unit 510 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

<Ninth embodiment>
Hereinafter, a relay device and a communication system according to a ninth embodiment of the present invention will be described.

  Referring to FIG. 28, the communication system according to the present embodiment is a system that communicates with PDA 210, which is an arbitrary telephone, through any of a plurality of lines using the Internet network or the like.

  The hardware configuration of the communication system according to the present embodiment is the same as that of the second embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 29, the program executed in the communication system has the following control structure. In the flowchart shown in FIG. 29, the process shown in FIG. 11 is given the same step number. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S540, first LAN controller 230 of base unit 220 receives information. The caller detection unit 150 of the base unit 220 refers to the transmission source of the information received by the first LAN controller 230, so that the information received by the first LAN controller 230 receives an incoming call from the line that updates the incoming order table 142. It is determined whether or not the information is information to be represented. In the present embodiment, it is assumed that the public network of the telephone company A is a line that updates the incoming order table 142. As a result, the caller detection unit 150 of the base unit 220 receives an incoming call for the telephone number of the A telephone company, which is a predetermined telephone number from the PDA 210, based on the information received by the first LAN controller 230. It will be judged whether the request is received or not. If it is determined that it represents an incoming call from the line to be updated in incoming call order table 142 (YES in step S540), the process proceeds to step S302. If not (NO in step S540), the process proceeds to step S541.

  In step S541, video phone control unit 244 of base unit 220 reads data representing the base unit 220 and all handset units 222 from data arrival unit table 142 stored in memory 126 to data control unit 128. Let When the information is read, the TV phone control unit 244 outputs the information read by the data control unit 128 to the communication control unit 232. The communication control unit 232 controls the second LAN controller 242 so as to transmit to the master device 220 and all the slave devices 222 that the incoming call has been detected. When the information output from the TV phone control unit 244 indicates the parent device 220 itself, the communication control unit 232 notifies the TV phone control unit 244 of an incoming call.

  In step S542, videophone control unit 244 of base unit 220 determines based on the time measured by timer 246 whether or not a time not to notify an incoming call has passed. If it is determined that the time has elapsed (YES in step S542), the process proceeds to step S304. If not (NO in step S542), the process proceeds to step S308.

  In step S <b> 543, caller detection unit 150 of base device 220 refers to the transmission source of information received by first LAN controller 230, so that information received by first LAN controller 230 updates incoming order table 142. It is determined whether or not the information represents an incoming call from the line. If it is determined that it represents an incoming call from the line to be updated in incoming call order table 142 (YES in step S543), the process proceeds to step S318. If not (NO in step S543), the process proceeds to step S300.

  The operation of the communication system based on the above structure and flowchart will be described.

  Through the process of step S300, caller detection unit 150 of base unit 220 determines whether the information received by first LAN controller 230 is information representing an incoming call from a line for updating incoming call order table 142 (step). S540). In this case, if it is determined that it represents an incoming call from the line to be updated in incoming call order table 142 (YES in step S540), through steps S302 to S306, videophone control unit 244 of base unit 220 has Then, it is determined whether or not a period not to notify the incoming call has passed (step S542). Initially, since the time not to notify an incoming call has not elapsed (NO in step S542), the processes in step S308, step S314, and step S542 are repeated. Eventually, the time during which no incoming call is notified elapses (YES in step S542), and therefore, base unit 220 or handset 222 that has been notified of the incoming call in step S302 starts ringing (step S304). As a result, when the TV phone control unit 244 of the parent device 220 receives a request for an incoming call for a predetermined phone number among a plurality of phone numbers from the PDA 210, the parent device 220 or the child device for a predetermined period of time. 222 is a device that restricts the output of information indicating that a request for an incoming call has been received (in this case, a ringing tone sounds). When ringing is started, step S308, step S314, and step S542 are repeated. When the call from the network is finished in step S314 (YES in step S314), the ringing tone is stopped (step S316), and the caller detection unit 150 of base unit 220 receives the information received by first LAN controller 230. It is determined whether or not the information represents an incoming call from a line for updating the order table 142 (step S543). In this case, since it is determined that it represents an incoming call from the line to be updated in incoming call order table 142 (YES in step S543), videophone control unit 244 of base unit 220 determines whether the value of timer 246 is less than the specified time. It is determined whether or not (step S318). In this case, if the value of timer 246 is less than the specified time (YES in step S318), data control unit 128 of base unit 220 updates the content of incoming order table 142, which is information stored in memory 126 ( Step S320). As a result, when the PDA 210 cancels the incoming call request before the length of the period during which the incoming call request is received from the PDA 210 exceeds the predetermined length, the data control unit 128 of the base unit 220 stores the memory 126 in the memory 126. The incoming order table 142, which is information to be stored, is updated.

  As described above, the communication system according to the present embodiment prevents the ringing of unnecessary ringtones for incoming calls for switching the incoming call order table by separating the identification incoming call line and the normal incoming call line. it can. Since ringing is prevented, an unexpected response by the user on the called side can be prevented. User discomfort due to the ringing tone can be eliminated. As a result, a relay device, a communication system, a relay program, which can realize an identification incoming call regardless of the time of call for a call from a general-purpose telephone, can prevent an unexpected response, and can eliminate discomfort, and A computer-readable recording medium on which the relay program is recorded can be provided.

  As a first modification, base unit 220 may operate as an answering machine if there is no response to an incoming call for a certain period determined by the user.

  As a second modification, in step S542, the TV phone control unit 244 of the handset 222 replaces the TV phone control unit 244 of the base unit 220 with a timer (in this case, the handset 222 also includes a timer). It may be determined whether or not a time not to notify an incoming call has passed based on the time measured by the user. As a result, the TV phone control unit 244 of the handset 222 becomes a device that receives an incoming call but does not notify the user that the incoming call is received (limits the output of information indicating that an incoming call request has been received). .

<Tenth Embodiment>
The relay device and communication system according to the tenth embodiment of the present invention will be described below.

  The hardware configuration of the communication system according to the present embodiment is the same as that of the second embodiment described above. The function about them is the same. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 30, the program executed in the communication system has the following control structure for incoming calls. In the flowchart shown in FIG. 30, the same step numbers are assigned to the processes shown in FIG. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S552, video phone control unit 244 of base unit 220 determines whether the time measured by timer 246 has reached a time predetermined by the user for automatic response (whether the timer has expired). To do. If it is determined that the timer has expired (YES in step S552), the process proceeds to step S554. If not (NO in step S552), the process proceeds to step S314. In step S554, base unit 220 and handset 222 stop ringing by a process similar to step S310.

  In step S556, communication control unit 232 of base unit 220 controls first LAN controller 230 to transmit information necessary for starting a call with PDA 210 and information necessary for an automatic response. . In the present embodiment, the information necessary for the automatic response is information representing a sound that has been received by the voice input / output unit 234 of the handset 222. The information received by the voice input / output unit 234 of the slave unit 222 is received by the second LAN controller 242. The information received by the voice input / output unit 234 of the slave unit 222 is stored in advance by the voice control unit 116 of the slave unit 222 in the G. 711 is encoded.

  The operation of the communication system based on the above structure and flowchart will be described.

[When there is an automatic response]
When the measurement of the timer 246 is started, the TV phone control unit 244 of the parent device 220 determines whether or not the timer has expired through the process of step S308 (step S552). Initially, since the timer does not expire (NO in step S552), the processes in step S314, step S308, and step S552 are repeated. Finally, since the timer expires (YES in step S552), the ringing tone stops (step S554). When ringing is stopped, communication control unit 232 of base unit 220 controls first LAN controller 230 so as to transmit information necessary for automatic response (step S556). Accordingly, when the length of the period during which the incoming call request is received from the PDA 210 exceeds a predetermined length, the communication control unit 232 causes the PDA 210 to receive information necessary for starting a call with the PDA 210 and the second LAN. The first LAN controller 230 is controlled so that the information received by the controller 242 is transmitted.

[When there is no automatic response]
Through the processing in steps S300 to S552, the incoming call detection unit 250 determines whether or not the call from the Internet network or the like has ended (step S314). If there is no automatic response, the call from the Internet network or the like does not end (NO in step S314), but after the processing in steps S308 to S314 is repeated, the call ends before timer 246 expires (step S314). In step S314, YES, the data control unit 128 of the base unit 220 updates the incoming order table 142 through the process of step S316 (step S320). As a result, the data control unit 128 of the parent device 220 stores the memory 126 when the PDA 210 cancels the incoming call request before the length of the period during which the incoming call request is received from the PDA 210 exceeds a predetermined length. The incoming order table 142 which is information to be updated is updated. If the call ends without an automatic response (YES in step S314), the terminal that outputs the ring tone out of base unit 220 and handset 222 stops ringing (step S316). ). When the ring tone stops, the data control unit 128 of the base unit 220 updates the contents of the incoming order table 142 stored in the memory 126 (step S320).

  As described above, the communication system according to the present embodiment enables an automatic response so that a sound captured by a specific child device can be confirmed from the outside. When the sound is confirmed from the outside, the communication system according to the present embodiment can be used for crime prevention. It is also possible to warn by voice or the like from the calling side. As a result, a relay device, a communication system, a relay program, which can realize an identification incoming call for a call from a general-purpose telephone regardless of the time of the call, can be used for crime prevention, and can give a warning, And a computer-readable recording medium on which the relay program is recorded.

  As a modification, the videophone control unit 184 may encode the information received by the voice input / output unit 162 instead of the voice input / output unit 162 in step S556. Master device 220 may encode the information received by voice input / output unit 162 using a dedicated device.

<Eleventh embodiment>
The relay device and communication system according to the eleventh embodiment of the present invention will be described below.

In the flowchart shown in FIG. 31, the processes shown in FIGS. 11 and 30 are given the same step numbers. These processes are the same. Therefore, detailed description thereof will not be repeated here.

  In step S560, video phone control unit 244 of base unit 220 determines whether or not the length of time measured by timer 246 exceeds a predetermined length of time (whether or not the timer has expired). . If it is determined that the timer has expired (YES in step S560), the process proceeds to step S562. Otherwise (NO in step S560), the process proceeds to step S314. In step S562, timer 246 of base unit 220 starts measuring the length of time.

  In step S564, communication control unit 232 of base unit 220 controls first LAN controller 230 to transmit information necessary for starting a call. As a result, a communication line is connected to the PDA 210.

  In step S566, communication control unit 232 of base unit 220 transmits information indicating that the incoming call is accepted (in the present embodiment, information indicating which handset 222 will accept the incoming call). And the base unit 220 and the handset 222 are stored in advance). As a result, a path is established for the handset 222 to accept image input and output it to the PDA 210. Video input unit 236 of handset 222 receives information representing an image by imaging. The LAN controller 260 of the handset 222 transmits information indicating that the incoming call is accepted, waits for establishment of a route, and transmits information representing the image accepted by the video input unit 236. The communication control unit 232 of the parent device 220 controls the first LAN controller 230 to transmit the information representing the image received from the child device 222 after transmitting the information indicating that the incoming call is accepted to the PDA 210.

  In step S568, handset 222 continues to transmit information representing an image to base unit 220. Meanwhile, the communication control unit 232 of the base unit 220 determines whether any of the following conditions is satisfied. The first condition is that the PDA 210 forcibly ends the call. The second condition is that the length of time that the timer 246 starts measuring in step S562 exceeds a predetermined time (and thus the handset 222 forcibly ends the call). If it is determined that at least one of the first condition and the second condition is satisfied (YES in step S568), the process proceeds to step S300. If not (NO in step S568), the process returns to step S568.

  The operation of the communication system based on the above structure and flowchart will be described.

  When the measurement of the length of time is started to determine whether or not to start an automatic response, the TV phone control unit 244 of the parent device 220 determines whether the timer 246 has expired through the processing up to step S308. It is determined whether or not (step S560). If timer 246 has expired (YES in step S560), timer 246 of base unit 220 again starts measuring the length of time in order to determine the remaining time of the automatic response (step S562). When measurement is started again, the communication control unit 232 of the parent device 220 connects the line with the PDA 210 through the process of step S554 (step S564). When the line is connected, the communication control unit 232 of the parent device 220 establishes a connection with the child device 222 that has transmitted the information indicating that the incoming call is accepted. Video input unit 236 of handset 222 receives information representing an image by imaging. The LAN controller 260 of the slave unit 222 transmits information indicating that the incoming call is accepted, and then waits for establishment of a connection, and transmits information representing the image accepted by the video input unit 236. The communication control unit 232 of the parent device 220 controls the first LAN controller 230 so as to transmit the information indicating the video transmitted by the child device 222 after transmitting the information indicating that the incoming call is accepted to the PDA 210 (step S566). ). When the information is transmitted, the TV phone control unit 244 of the parent device 220 determines whether or not a predetermined condition is satisfied (step S568). If the predetermined condition is satisfied (YES in step S568), incoming call detection unit 250 of base unit 220 determines again whether an incoming call has been detected from the Internet network (step S300).

  As described above, since the communication system according to the present embodiment can transmit a camera image in a communication system capable of automatic response, it is possible to check a video around a specific communication device from the outside. . When the video can be confirmed, the user can confirm the situation inside the house from the outside. Since the internal situation can be confirmed, the communication system according to the present embodiment can be used for crime prevention, nursing care, pet situation confirmation, and the like. As a result, a relay device, a communication system, a relay program, and a relay that can realize an identification incoming call for a call from a general-purpose telephone regardless of the time of the call, and can be used for crime prevention, nursing care, pet status confirmation, etc. A computer-readable recording medium in which the program is recorded can be provided.
