  The present invention relates to a dealing call system that is used when trading futures and financial products such as exchanges and securities mainly at banks and securities companies, and a method for controlling a scheduler linked function for a dealing call system.

  2. Description of the Related Art Conventionally, in a dealing call terminal device used in a dealing call system, two call handsets are mounted per unit, and it is possible to make calls with different parties at the same time using these call handsets. It can be done. In addition, the dealing call terminal device has a dial button for making a call by manually pressing a dial in the same manner as a normal telephone, and a number of registration calls for calling a call partner by making a call with a one-touch operation. Buttons are registered, and telephone numbers of analog / digital public lines and leased lines are registered, and by pressing the registration button, it is possible to easily call the other party and make a call. Further, the dealing call terminal device can notify the callee that he / she is absent by making an absence setting when he / she is away from the telephone and calling again.

  By the way, in the existing dealing call terminal device, the same tool user that has been used in recent years is not linked to the schedule management tool that can confirm the schedule registered by others, and the schedule to leave is registered Even so, the absence registration setting in the dealing call terminal device needs to be individually performed for each dealing call terminal device. Further, when the absence setting is performed, all incoming calls at the same time are restricted for two call lines that can be used.

  Incidentally, as a well-known technique related to the line control of a general exchange, for example, a line control apparatus that enables an interrupt connection to an arbitrary line even in the case of a time division digital switching system specification (refer to Patent Document 1). ) And the like.

It is the flowchart which showed the remaining part of the control operation process of the dealing telephone system shown in FIG.

  Hereinafter, the dealing call system of the present invention and the control method of the scheduler linked function for dealing call system will be described in detail with reference to the drawings.

  FIG. 1 is a schematic diagram exemplifying speech path control (connectable status) during operation when the incoming call restriction of the scheduler interlock function is partially canceled in the control method of the scheduler interlock function for the dealing call system of the present invention. is there.

  Here, two (2) handsets are connected and two-line simultaneous call is possible (one is fine, but usually multiple are installed in the same installation environment) and each dealing call terminal device and each dealing In addition to being connected to a call terminal device, it relates to outgoing / incoming calls for performing exchange operations between each dealing call terminal device and a general line of a communication partner via a public network such as a local area network (LAN). A schedule management tool for a schedule management terminal device (schematically shown in FIG. 1) is used as a control method of a scheduler interlock function for a dealing call system having a line control device that controls and manages all communication paths. Schedule information including the absence schedule registered in the management server (schematically shown in FIG. 1) is acquired on the line control device side, The line control apparatus, as the control of the communication path, is performed automatically by including a release part for incoming regulations based on the schedule information to the dealing communication terminal apparatus.

  Specifically, on the line control device side, by partially canceling the incoming call restriction, the call is sent between the exempt line on the communication partner's line and the non-restricted device on each dealing call terminal device via the public network. In addition to making an incoming call, the communication path is controlled so that the incoming call is not made on the restricted extension of each dealing call terminal device by restricting the connection with the restricted line in the communication partner line. Thus, for example, in FIG. 1, it is shown that the connection is restricted so that incoming calls are not made to other devices other than the own device in each dealing call terminal device with the restriction target line in the communication partner's general line. ing.

  By the way, it is preferable that the schedule information includes an extension number for each dealing call terminal device, an absent date and absence time zone indicating the absence schedule, and an incoming call restriction excluded telephone number. In such a case, the line controller side cancels a part of the incoming call restriction based on the extension number and the telephone number excluding the incoming call restriction, and restricts the connection based on the extension number, the absent date and the absent time zone, and receives the incoming call. Control the communication path so that it is not performed. As a result, incoming calls can be automatically restricted during the absence hours according to the schedule registered in the schedule management tool, and incoming calls can be restricted when you want to respond only to incoming calls from specific parties. A function to cancel a part is built, solves the problems in the conventional dealing call system, has a function linked with the scheduler, and can improve the inconvenience in the function at the time of absence setting and the incoming call restriction function It will be a thing.

Further, during operation of the scheduler interlocking function, the operation state of the scheduler interlocking function is displayed by displaying “incoming call restriction” or “incoming call restriction [excluded]”.

  FIG. 6A is a flowchart of a basic part of control operation processing (speech path control of the line control device 1) of the dealing call system according to the first embodiment. The control operation process here shows an in-system operation flow from when the schedule registration occurs in the schedule management terminal device 4 until the line control device 1 receives the information and restricts the incoming call to the dealing call terminal device 2. Is.

  More specifically, in the control operation process, first, based on data registered in the schedule management server 5 in order to check whether or not the user has registered the schedule with the schedule management tool in the schedule management terminal device 4. Then, it is determined from the schedule management terminal device 4 whether or not the “absence schedule registration” information of the schedule information exists (step S1). As a result of the determination, if there is no “absence schedule registration” information, the operation process is terminated as no processing. If there is “absence schedule registration” information, the schedule is continuously registered based on the data registered in the schedule management server 5. It is determined whether or not the management terminal device 4 has the extension number registration of the dealing call terminal device 2 used by the user (step S2). As a result of this determination, if there is no extension number registration, the operation process is terminated as no processing, but if there is an extension number registration, the incoming call arrives at the schedule management terminal device 4 based on the data registered in the schedule management server 5 subsequently. It is determined whether or not there is no restriction excluded telephone number registration (step S3). As a result of this determination, if there is an incoming call restriction excluded telephone number registration, the process proceeds to the remaining part of the control operation process described later with reference to FIG. After performing processing for notifying the line control device 1 of the absence schedule registration information (notification contents: extension number, date, absence time zone) (step S4), the line control device 1 determines whether or not there is an incoming call. Judgment is made (step S5).

  As a result of this determination, if there is no incoming call, the operation processing is terminated as no processing, but if there is an incoming call, it is determined whether or not it is a date when there is an extension number registration that is scheduled to be absent for the dealing telephone terminal 2 (step) S6).

  As a result of this determination, if it is not a date when there is an extension number that is scheduled to be absent, the incoming call is received at the dealing call terminal device 2 and a response is made possible (step S7). If it is a date when there is an extension number that is scheduled to be absent, it is subsequently determined whether or not it is an incoming call to the extension number that is scheduled to be absent (step S8), so that the extension number of the destination is the extension number that is registered as absent Check whether or not. As a result of this determination, if the incoming call is not to the extension number scheduled to be absent, the incoming call is received at the dealing call terminal device 2 and a process is made to make a response possible (step S7). If it is an incoming call to the scheduled extension number, it is subsequently determined whether or not the incoming call to the extension number registered for the absence schedule is an incoming call within the scheduled absence period (step S9).

  If the result of this determination is that the incoming call is not within the scheduled absence time zone, the incoming call is received at the dealing call terminal device 2 and the response processing is possible (step S7). If it is an incoming call within the time period, the dealing call terminal device 2 determines whether or not there is no “absence schedule release” information for the line control device 1 (step S10). As a result of this determination, if there is “absence schedule release” information, the incoming call is received at the dealing call terminal device 2 and the response process is performed (step S7). If there is no “absence schedule release” information, the line control device 1 temporarily responds, and after a transition is made to the call state for the called party, a fixed message that informs the called party of the absence from the talkie unit 109 After performing the process of sending (voice) (step 11), the line control apparatus 1 ends the call (step 12), and the operation process is terminated.

  By the way, when the dealing call terminal device 2 performs an operation of canceling the absence, the dealing call terminal device 2 is in the absence state based on the schedule information from the schedule management terminal device 4 in the dealing call terminal device 2. Even if the incoming call occurs after the operation even if the incoming call is within the scheduled time of absence by performing an operation when the absence indicator is displayed on the board, the call can be answered as usual. It is the operation to do.

  FIG. 6B is a flowchart of the remaining portion of the control operation process of the dealing call system according to the first embodiment. This control operation process is performed when there is an incoming call restriction excluded telephone number registration as a result of the determination as to whether or not there is an incoming call restriction excluded telephone number registration (step S3). , The schedule information absence schedule registration information (notification contents: extension number, date, absence time zone, incoming call restriction excluded telephone number) is notified to the line control device 1 (step S13), and then the line control device 1 receives an incoming call. It is judged (step S14).

  As a result of this determination, if there is no incoming call, the operation processing is terminated as no processing, but if there is an incoming call, it is determined whether or not it is a date when there is an extension number registration that is scheduled to be absent for the dealing call terminal device 2 (step S15). ) As a result of this determination, if it is not a date when there is an extension number that is scheduled to be absent, the incoming call is received at the dealing call terminal device 2 and a response is made possible (step S16). If it is a date when there is an extension number that is scheduled to be absent, it is subsequently determined whether or not it is an incoming call to the extension number that is scheduled to be absent (step S17), so that the extension number of the destination is the extension number that is registered as absent Check whether or not. As a result of this determination, if the incoming call is not to the extension number scheduled to be absent, the incoming call is received at the dealing call terminal device 2 and the process is made possible to respond (step S16). If it is an incoming call to a scheduled extension number, it is subsequently determined whether the incoming call is from a telephone number other than the incoming call restriction exclusion target telephone number (step S18). As a result of this determination, if the incoming call is not from a phone number that is not subject to incoming call restriction, an incoming call is received at the dealing call terminal device 2 and a process for making a response is possible (step S16). If the incoming call is from a phone number other than the call restriction exclusion phone number, it is subsequently determined whether or not the incoming call to the extension number registered for the absence schedule is an incoming call in the absence time zone (step S19).

  If the result of this determination is that the incoming call is not within the scheduled absence time zone, the incoming call is received at the dealing call terminal device 2 and the response processing is possible (step S16). If it is an incoming call within the time zone, the dealing call terminal device 2 subsequently determines whether or not there is no “absence schedule release” information for the line control device 1 (step S20). As a result of this determination, if there is “absence schedule release” information, the incoming call is received at the dealing call terminal device 2 and the response process is performed (step S16). If there is no “absence schedule release” information, the line control device 1 temporarily responds, and after a transition is made to the call state for the called party, a fixed message that informs the called party of the absence from the talkie unit 109 After performing the process of sending (voice) (step 21), the line control apparatus 1 ends the call (step 22), and the operation process is terminated.

  The operation of canceling the absence from the dealing call terminal device 2 here is also as described above.
