  FIG. 3 is a block diagram showing an outline of the hardware configuration of the terminal device according to an example of the embodiment of the present invention.

  The terminal device 2 includes the components shown in FIG. 2 (handset 200, dial key 210, disconnect key 211, front page key 212, rear page key 213, non-response automatic transmission key 220, non-response automatic transmission lamp 221 and operation panel 230. ), An MPU (Micro Processing Unit) 240, a ROM 241, a RAM 242, a reception buffer 251, a transmission buffer 252, a connection interface 260, an operation panel controller 270, an image memory 271, and a lamp. A drive unit 280 and a key input interface 290 are provided.

  The MPU 240 is a processor that controls the terminal device 2 in an integrated manner. The ROM 241 stores a call control program and data for controlling the terminal device 2 in advance. The RAM 242 temporarily stores programs executed by the MPU 240.

  The reception buffer 251 is a buffer that receives a call control message indicating the state of each line accommodated in the switching apparatus 4. The transmission buffer 252 is a buffer that transmits a call control message indicating the operation contents of the terminal device 2 and the like to the exchange device 4. These buffers are controlled by the MPU 240 executing a call control program.

  The reception buffer 251 and the transmission buffer 252 are connected to, for example, a D-channel signal line for a control signal of the ISDN basic interface. The handset 200 is connected to, for example, a B channel signal line for voice and data signals of the ISDN basic interface.

The MPU 240 is notified of the status of the detected various keys.

  The above-described configurations of FIGS. 1 to 3 describe the main configuration in describing the features of the present invention, and are not limited to the above configuration. Further, the configuration of a general telephone exchange system, terminal device, and exchange device is not excluded.

  FIG. 4 is a block diagram showing a functional configuration related to automatic transmission for a non-response of a terminal device according to an example of an embodiment of the present invention.

  Note that the terminal device 2 has the same functions as those in the past, such as a function for receiving an incoming call in a standby state and starting a call by a user operation, and a function for making a call by a user operation in a standby state. Therefore, the description thereof will be omitted, and the following description will focus on functions and operations when an incoming call is accepted during a call.

  The terminal device 2 includes an incoming call monitoring unit 400, an incoming call control unit 410, a display control unit 420, a non-response timer monitoring unit 430, a disconnection monitoring unit 440, an outgoing call control unit 450, and a line key data storage unit 460. The incoming line data storage unit 470 and the automatic transmission data storage unit 480 are provided.

  These functional units are realized, for example, by the MPU 240 executing a call control program loaded from the ROM 241 to the RAM 242. The call control program is stored in the ROM 241 in advance (for example, when the terminal device 2 is manufactured). The line key data storage unit 460, the incoming line data storage unit 470, and the automatic transmission data storage unit 480 may be realized by the ROM 241 or the RAM 242.

  First, the line key data storage unit 460, the incoming line data storage unit 470, and the automatic transmission data storage unit 480 will be described.

  The line key data storage unit 460 stores, for each line key, line key data including information on the line assigned to the line key.

  For example, as shown in FIG. 5, the line key data is arranged and stored in page order (1 to m pages) and line key order (1 to n lines, in this embodiment, n = 15 lines). The line key data includes a line number 461, a line type 462 indicating the type of a station line, a dedicated line, etc., a line name 463 displayed on the operation panel 230, and valid / invalid of automatic transmission of an unanswered incoming call. And an automatic transmission setting 464 indicating the above.

  Each line key data is set by an operation manager or the like via the data management device 3. The operation manager determines to which line key on which page the line information is assigned. Of course, each line key data may be set from the operation panel 230 of the terminal device 2.

  The automatic transmission setting 464 may be effectively set when the user or the operation manager of the terminal device 2 is an important customer line, for example. Then, when an incoming call from an important customer is not answered, it is automatically sent.

  The incoming line data storage unit 470 stores, for each line key, incoming line data including information related to incoming calls for the line assigned to the line key.

  For example, as shown in FIG. 6, the incoming line data is arranged and stored in page order (1 to m pages) and line key order (1 to n lines, in this embodiment, n = 15 lines). The incoming line data includes the line number 471, the line key numbers (K1 to K15) 472 indicating the display position in the main area 231 of the operation panel 230, and the terminal device 2 that receives a call and makes a call (call connection). It includes a terminal number 473 indicating (own device or other device) and dial information 474 such as a telephone number of a caller.

  The line number 471 is set in the same manner when the line number 461 of the line key data is set. The line key number 472 is preset in the order of 1 to n for each page. The terminal number 473 and the dial information 474 include the terminal number of the terminal device 2 (self device or other device) that made a call connection to the incoming line by the incoming call control unit 410 and the dial information of the caller of the incoming call. Is set. Note that the terminal device 2 transmits the terminal number of the terminal device 2 to another terminal device 2 via the exchange device 4 when the call connection is made.

  The automatic transmission data storage unit 480 stores automatic transmission data for one line. The automatic transmission data is configured as shown in FIG. 7, for example. The automatic transmission data includes a line number 481 and dial information 482. As will be described later, the line number 481 and the dial information 482 are set when the automatic response setting 464 of the incoming line that has made a non-response is set valid by the non-response timer monitoring unit 430.

  Of course, the configurations of the above-described line key data, incoming line data, and automatic transmission data are not limited to the above configurations.

  Returning to FIG. 4, the description will be continued.

  The incoming call monitoring unit 400 monitors incoming calls on lines other than the line being talked on. For example, the incoming call monitoring unit 400 determines whether incoming data (call control message indicating incoming call) has been transmitted from the switching device 4 during a call, and notifies the incoming call control unit 410 when the incoming data is received. To do. The incoming data includes, for example, the line number of the incoming line, the dial information of the caller, and the like.

  The incoming call control unit 410 performs incoming call processing for incoming calls on lines other than the line being talked on. For example, when the incoming call control unit 410 receives a notification from the incoming call monitoring unit 400, the incoming call control unit 410 performs ringer control to ring the ringer (ring the ringer even during a call). In addition, the display control unit 420 is instructed to perform display control when an incoming call is received.

  Further, for example, the incoming call control unit 410 acquires a line number included in the received incoming call data, and determines whether or not the automatic transmission setting 464 of the line key data corresponding to the line number is valid. If it is valid, the dial information of the caller included in the incoming data is set as the dial information 474 of the incoming line data corresponding to the line number. Note that the dial information 474 may be set regardless of whether the automatic call setting 464 is valid. In addition, when the automatic call setting 464 is valid, the incoming call control unit 410 starts a non-response timer used for controlling a non-response line as will be described later.

  The display control unit 420 performs display control of the display of the operation panel 230. For example, the display control unit 420 sets each line key data in the main area 231 based on line key data of a line key included in a specified page (for example, a default first page or a page specified by the user). A corresponding line name 463 is displayed in the area of the line key 233. Any one of the data included in the line key data, or any two or more data may be displayed. When another page is designated by the previous page key 212 or the rear page key 213, the display is changed based on the line data of the line key included in the designated page.

  As will be described later, in the sub area 232, when a line of a page other than the page currently displayed in the main area 231 arrives, the line information of the incoming line includes the line key (K16 to K20). Since it is displayed in one of the areas 233, the area of the line key (K16 to K20) 233 is empty when there is no incoming call.

  For example, when receiving an instruction from the incoming call control unit 410, the display control unit 420 specifies incoming line data corresponding to the incoming line number. Then, the line key number 472 included in the incoming line data is acquired.

  When the page including the incoming line key is a page being displayed in the main area 231, the display control unit 420 displays the line key (K1 to K15) 233 corresponding to the acquired line key number (K1 to K15) 472. An image notifying the incoming call is displayed around the area. For example, as shown in FIG. 14, the incoming image 235 of a predetermined color is blinked. Of course, the display position and display mode of an image for notifying an incoming call are not limited to the above.

  On the other hand, when the page containing the incoming line key is not the page currently displayed in the main area 231, the display control unit 420 sets the line key number most frequently among the line keys (K16 to K20) 233 in the sub area 232. A small, free line key 233 is identified. Based on the line key data of the incoming line key, the corresponding line name 463 is displayed in the area of the specified line key 233, and an image notifying the incoming call is displayed around the area of the specified line key 233. To do. For example, as shown in FIG. 15, an incoming image 235 of a predetermined color is blinked. Of course, the display position and display mode of an image for notifying an incoming call are not limited to the above.

  In addition, for example, when the display control unit 420 receives an instruction to change the display from the non-response timer monitoring unit 430 while displaying an image notifying the incoming call, the display control unit 420 changes the display mode of the image according to the instruction. (For example, change the color).

  The non-response timer monitoring unit 430 performs addition according to the timer and control according to the timer value after the above-described non-response timer is started. For example, when the value of the non-response timer exceeds a predetermined first timer value (for example, 5 seconds), the non-response timer monitoring unit 430 causes the display control unit 420 to change the mode of the image that notifies the incoming call. Instruct. In addition, when the value of the non-response timer exceeds a predetermined second timer value (for example, 10 seconds), the display control unit 420 is instructed to change the mode of the image informing the incoming call, The line number 471 and dial information 474 are acquired from the incoming line data and set as the line number 481 and dial information 482 of the automatic call data.

  The disconnection monitoring unit 440 monitors whether or not the call connection of the line being talked is disconnected. For example, the disconnect monitoring unit 440 determines whether the disconnect key 211 is pressed based on a signal sent from the key input interface 290. When the disconnect key 211 is pressed, automatic transmission data is acquired from the automatic transmission data storage unit 480. When the line number 481 and the dial information 482 are set, it is determined whether or not the automatic answering function is valid. A call request is sent to the call control unit 450.

  Note that the disconnect monitoring unit 440 stores the valid / invalid setting of the non-response automatic transmission function of the terminal device 2 based on a signal sent from the key input interface 290 when the non-response automatic transmission key 220 is pressed. Keep it.

  The outgoing call control unit 450 performs automatic outgoing call processing to the caller of the incoming call that has failed. For example, when receiving an instruction from the disconnection monitoring unit 440, the transmission control unit 450 acquires automatic transmission data from the automatic transmission data storage unit 480, and uses the line number 481 and dial information 482 included in the data to determine the line number. Transmission information having the transmission source 481 and the dial information 482 as the destination is generated and transmitted to the exchange apparatus 4. Further, after the transmission information is transmitted, the line number 481 and the dial information 482 are deleted.

  The above components are classified according to main processing contents in order to facilitate understanding of the configuration of the terminal device 2. The present invention is not limited by the way of classification and names of the constituent elements. The configuration of the terminal device 2 can be classified into more components according to the processing content. Moreover, it can also classify | categorize so that one component may perform more processes. Further, the processing of each component may be executed by one hardware or may be executed by a plurality of hardware.

A characteristic operation of the terminal device 2 will be described with reference to FIGS. In the following,
An operation when the terminal device 2 is talking on a certain line and an incoming call is received from another line during that time will be described.

  FIG. 8 is a flowchart of incoming call monitoring processing according to an example of the embodiment of the present invention. This flow is started periodically.

  In S101, the incoming call monitoring unit 400 monitors incoming calls on lines other than the line that is in a call. Specifically, the incoming call monitoring unit 400 determines whether incoming data has been received from the exchange device 4 during a call. If incoming data is received (S101: YES), the process proceeds to S102. If no incoming data has been received (S101: NO), this flow ends.

  In S102, the incoming call monitoring unit 400 notifies the incoming call control unit 410 of an incoming call activation request. Then, this flow ends.

  FIG. 9 is a flowchart of the incoming call processing according to an example of the embodiment of the present invention. This flow is started when the incoming call control unit 410 receives an incoming call activation request. The incoming call control unit 410 instructs the display control unit 420 to perform display control at the time of incoming call.

  In S201, the incoming call control unit 410 starts ringer control. Specifically, the incoming call control unit 410 sounds a ringer. Then, the process proceeds to S202.

  In S202, the incoming call control unit 410 determines whether or not the automatic call setting for a line that has been received during a call is valid. Specifically, the incoming call control unit 410 acquires the line number included in the received incoming data, and refers to the line key data storage unit 460 to automatically set the line key data corresponding to the acquired line number. It is determined whether 464 is valid. If the automatic call setting 464 is valid (S202: Valid), the process proceeds to S203. When the automatic call setting 464 is invalid (S202: Invalid), this flow is finished.

  In S203, the incoming call control unit 410 records the dial information of the transmission source of the line that has arrived during the call. Specifically, the incoming call control unit 410 sets the dial information of the caller included in the received incoming call data as dial information 474 of incoming line data corresponding to the acquired line number. Then, the process proceeds to S204.

  In S204, the incoming call control unit 410 starts a non-response timer. Then, this flow ends.

  In S211, the display control unit 420 starts non-response incoming call display control (first stage). Specifically, the display control unit 420 acquires a line number included in the received incoming data, refers to the incoming line data storage unit 470, identifies incoming line data corresponding to the line number, and The line key number 472 included in the incoming line data is acquired.

  When the page including the incoming line data corresponding to the incoming line number is the page being displayed in the main area 231, the display control unit 420 displays the line key corresponding to the acquired line key number (K1 to K15) 472. An image notifying the incoming call is displayed around the area (K1 to K15) 233.

  For example, as shown in FIG. 14A, when the line key number of the incoming line is K7, the incoming image 235 is displayed around the area of the line key 233. The incoming image 235 in S211 is the same as that for a normal incoming call (incoming in a standby state). Although not shown, a predetermined image having a mode different from the incoming image 235 can be displayed around the area of the line key 233 during a call.

  If the page containing the incoming line data corresponding to the incoming line number is not the page currently displayed in the main area 231, the display control unit 420 selects the line key (K16 to K20) 233 in the sub area 232 from the line key. The vacant line key 233 having the smallest key number is specified. Also, with reference to the line key data storage unit 460, the line name 463 included in the line key data corresponding to the line number included in the received incoming data is acquired. Then, the acquired line name 463 is displayed in the area of the specified line key 233, and an image notifying the incoming call is displayed around the area of the specified line key 233.

  For example, as shown in FIG. 15, when the K16 line key is empty, an incoming call image 235 is displayed around the area of the line key 233. The incoming image 235 in S211 can be the same image as in the case of normal incoming (incoming in the standby state).

  The display control unit 420 starts display control as described above, and ends this flow.

  FIG. 10 is a flowchart of the non-response timer monitoring process according to an example of the embodiment of the present invention. This flow is started periodically.

  In S301, the non-response timer monitoring unit 430 acquires the value of the non-response timer. Then, the process proceeds to S302.

  In S302, the non-response timer monitoring unit 430 determines whether or not the non-response timer is being activated. For example, if the timer value acquired in S301 is a predetermined initial value, it is determined that it has not been started. If the non-response timer is not activated (S302: NO), this flow ends. If the non-response timer is being activated (S302: YES), the process proceeds to S303.

  In S303, the non-response timer monitoring unit 430 adds the timer value by a predetermined unit. Then, the process proceeds to S304.

Moreover, it can also divide | segment so that one process unit may contain many processes.

  The embodiment of the present invention has been described above. According to this embodiment, it is possible to make a call more promptly with respect to an incoming call that is a non-response.

  More specifically, in the above-described embodiment, when a call is not responded to an incoming call to a line other than the line being talked to, the other line that is not answered after the call ends. Calls are automatically sent to the incoming caller. With such a configuration, even if the user does not perform an operation, the incoming call that is not answered is transmitted more promptly. For example, in a situation where an order transaction is performed as in a dealing business, it is possible to respond more quickly to a customer who has failed to respond.

  In the above-described embodiment, it is possible to set automatic call setting valid / invalid for each line. With such a configuration, it is possible to set so as to perform a non-response automatic call on a high-priority line. For example, in a situation where an order transaction is performed as in a dealing service, the automatic transmission setting can be enabled for a dedicated line of an important customer.

  Moreover, in said embodiment, the non-response automatic transmission function of a terminal device can be set to enable / disable by the non-response automatic transmission key. With such a configuration, it is possible to collectively enable / disable the non-response automatic transmission function.

  Further, in the above embodiment, when the second timer value expires, the line number and dial information of the incoming line that is not responding are saved. With such a configuration, an incoming call that has been unanswered for a longer period of time can be automatically sent as a more important incoming call.

  In the above embodiment, the incoming image is displayed for the line key corresponding to the incoming line that is not responding, and the mode of the incoming image is changed step by step as time passes. With such a configuration, it is possible to notify the user that there is no response in an easy-to-understand manner, and to prompt the user to respond.

  The above-described embodiments of the present invention are intended to illustrate the gist and scope of the present invention and are not intended to be limiting. Many alternatives, modifications, and variations will be apparent to those skilled in the art.

  For example, in the above-described embodiment, the incoming automatic outgoing call data that has not been answered is stored for one line, but may be stored for a plurality of lines. In this case, after the call is terminated, the transmission control unit 450 may perform automatic transmission based on the automatic transmission data selected according to a predetermined priority order. The predetermined priority order may be, for example, the order from the smallest page number and line key number, or the order from the oldest time when the automatic transmission data is stored. Priorities may be given to the line key data, and the order may be used.

  Further, for example, in the above embodiment, when the second timer value expires, the line number and dial information of the incoming line that is not responding are saved, but immediately when there is an incoming call during a call, The line number and dial information may be saved. In this way, even if there is no response for a long time, it can be a target for automatic transmission.
