  Then, the line interface 2 performs output interface processing set in advance on the audio signal, and transmits it to the call destination via the general public line X.

  Next, an operation when a telephone call is made via the network NT using the telephone system S according to the embodiment will be described.

  When a call is made via the network NT using the telephone system S according to the embodiment, as in the case where the call is made via the general public line X, an operation to that effect is executed in the key operation unit 60 of the handset 51. Then, an operation signal indicating that the operation has been performed is output from the child device 50 to the parent device 1, whereby the control unit 13 of the parent device 1 connects the cross switch 6 in the switching unit 5 to the codec unit. Switch to 42 side.

  On the other hand, an audio signal or the like provided for a call via the network NT is a data transmission standard that the network NT should comply with (more specifically, for example, TCP / IP (Transmission when the network NT is the Internet). In accordance with (Control Protocol / Internet Protocol) standard), the data is encoded and packetized, and is input to the interface 72 of the connection device 70.

  Then, input interface processing set in advance by the interface 72 is performed and output to the USB interface 3 of the parent device 1 via the network telephone function unit 73 and the USB interface 71.

  Then, the USB interface 3 performs a preset input interface process on the audio signal or the like in the packet and outputs the processed signal to the codec unit 4.

  Then, the network telephone function unit 73 performs encoding processing, packetization processing, and the like in conformity with the above-described standard on the output audio signal, and transmits this to the network NT via the interface 72. Transmit to the other party via NT.

  The telephone number assigned to the connection device 70 as a transmission source is packetized together with the transmission signal at the time of the packetization process at the start of a call and transmitted to the call destination.

  Next, call processing according to the first embodiment will be specifically described with reference to FIGS.

  In the telephone system S according to the first embodiment described above, when another call is received from the other party via the network NT during the call via the network NT, the call is made until then. It is possible to start a call for a newly received call after temporarily placing the held call on hold. In addition, even when a new call is received via the network NT while holding a plurality of the above-described hold states, it is possible to respond to the new call.

  At this time, in the telephone system S according to the first embodiment, in preparation for the case where there are a plurality of incoming calls via the network NT in parallel, the call attributes (more specifically, “busy”) Call, "calling operation" call by the operator of the telephone system S, "incoming" call (i.e., ringing sound is ringing), call "on hold" by the operator and call partner The priority order corresponding to the five types of attributes of the call “held” by the previous operation is preset, and the priority order information indicating the priority order is stored in the nonvolatile area of the memory 13A. .

  More specifically, the priority information 80 to 84 corresponding to the above-described attributes one-on-one is stored in the non-volatile area of the memory 13A as illustrated in FIG.

  At this time, since a call during a call and a call during an outgoing operation cannot coexist at the same time, the priority information 80 and 81 corresponding to each other is equal to each other and has the highest priority for other attributes. It is said that.

  Further, in the priority information 82 corresponding to the incoming call, as a further subdivided priority, when there are a plurality of incoming calls, the call with the earlier arrival time to the corresponding telephone system S is given. The higher the priority, the higher the priority.

  Further, in the priority information 83 corresponding to the call put on hold by the operator of the telephone system S, when there are a plurality of calls that are put on hold by the operation of the operator as a further subdivided priority order The higher the priority is, the higher the priority is for a call having a later time of transition to the hold state.

  Furthermore, in the priority information 84 corresponding to the call that is put on hold by the operation of the other party of the call, there are a plurality of calls that are put on hold by the operation of the other party as a further subdivided priority. At this time, the call with the later time when the state is shifted to the hold state has a higher priority.

  In the telephone system S in which the priority information 80 to 84 illustrated in FIG. 2A is stored in the memory 13A, a case where a new call is received from the telephone system S or the telephone system When a new call origination operation is executed in S, as shown in FIG. 2B, the attribute of each call that is the operation target at that time is any of the above five types of attributes. (Step S1), and based on the priority information 80 to 84 corresponding to the confirmed attribute, the current priority of the call is confirmed (step S2), and the confirmed priority is further confirmed. In response to this, the display contents on the display unit 61 are switched and a call switching operation or the like is executed (step S3), and the processing corresponding to the switched call is actually executed (step S4). .

  Thereafter, it is confirmed whether or not the processing for all calls has been completed (step S5). When the processing for all calls has been completed (step S5; YES), the call processing according to the first embodiment is performed as it is. On the other hand, when there are still unprocessed calls (more specifically, for example, on hold) (step S5; NO), the remaining calls are processed according to the priority. Therefore, the process returns to step S1.

  Next, a specific example of the operation shown in FIG. 2B will be described with reference to FIG. FIG. 3 shows a case where an incoming call is received from the destination “XX” while a call from the destination “XX” is being executed while a call from the destination “XX” is held. The following describes the operation of the control units 13 and 55 and the change of the display mode on the display unit 61 for the above process and the process when the call with the other party “XX” is terminated.

  In other words, as illustrated in FIG. 3, when a call is made with a destination “XX” while a call from the destination “XX” is held, the destination “XX” Is stored in the volatile area of the memory 13A, and the operation information 100 indicating that the call of the other party is on hold and the operation information 101 indicating that the call of the other party called “OO” is in a call state. Accordingly, a display “Call partner: OO” is executed on the display unit 61.

  In this state, when an incoming call is received from the other party “XX”, a bell sound or the like indicating the incoming call is sounded from a speaker (not shown in FIG. 1), and the handset 50 is gripped correspondingly. Then, the operator who is talking to the other party “OO” presses a call button (not shown) in the key operation unit 60.

  By this operation, the call with the destination “XX” is in the “in-call” state, and based on the priority information 80 and 83 shown in FIG. The operation information 102 indicating that the call is in a call state is newly held in the volatile area of the memory 13A as the highest priority operation information, and the content of the operation state 101 is changed from “busy” to “hold” accordingly. After being changed to “medium”, it is continuously held in the memory 13 </ b> A, and a display of “call partner; xx” is newly executed on the display unit 61.

  Next, when the call with the other party “XX” is ended, an end button (not shown) in the key operation unit 60 is pressed by the operator, and a call with the other party “XX” is made by this operation. The operation information 102 is erased from the memory 13A while being disconnected. Then, based on the priority order information 83 shown in FIG. 2A, the operation information 101 indicating that the call of the other party “OO” is in the hold state has the highest priority and is in the volatile area of the memory 13A. Accordingly, a display of “holding partner; OO” is newly executed on the display unit 61.

  Note that, during the series of operations described above, the call with the other party “Ox” is continuously held.

  As described above, according to the call processing in the telephone system S according to the first embodiment, the control for each call is executed according to the priority set in advance based on the attribute of each call. Calls having different attributes are not controlled simultaneously and, as a result, even when simultaneous communication using a plurality of calls is performed, the control can be performed efficiently and with improved operability.

  Further, since only the operation information corresponding to the call currently controlled based on the priority order is displayed on the display unit 61, for example, when performing simultaneous communication using a plurality of calls by the small handset 50, the display unit Even when the number of displayable characters as 61 is small, the communication can be performed efficiently and with improved operability.

  Furthermore, since the priority of the call currently being talked is the highest priority as the priority information 80, it is possible to accurately grasp the state of the call that is currently being talked (for example, the destination number) and perform the call. Can continue.

  Furthermore, as the priority information 81, the priority of the call that is currently being sent is the first priority equivalent to that of the call that is being called, so the state of the call that is currently being sent (for example, the outgoing call) The telephone number can be accurately grasped and the call can be continued.

  Further, as the lottery order information 82, a call with an earlier arrival time has a higher priority, so that it can be used in response processing in order from the first incoming call, so that the caller does not have to wait for a long time. Communication can be started or resumed.

  Furthermore, as the priority information 83, a call with a later time that is shifted to the hold state by the operation of the operator of the slave unit 50 has a higher priority, so the call that has been shifted to the hold state most recently It is possible to communicate while quickly recalling the contents.

  Furthermore, as the priority information 82 and 83, since the priority of the incoming call is higher than the priority of the call that is put on hold by the operation of the operator, priority is given to establishment of the call and simultaneous communication is performed. can do.

  In addition, as the priority information 84, a call with a later time when the call is shifted to the hold state by the other party's operation has a higher priority, so the contents of the call that has been transferred to the hold state most recently are displayed. You can communicate while remembering quickly.

  Further, as priority information 82 to 84, the priority of the incoming call> the priority of the call held by the operator of the slave unit 50> the priority of the call put on hold by the communication partner Therefore, simultaneous communication can be efficiently realized in a state in conformity with the actual communication / calling mode while giving priority to the establishment of a call.

(II) Second Embodiment Next, a second embodiment which is another embodiment according to the present application will be described with reference to FIGS. 4 is a diagram illustrating the contents of the priority information in the memory of the telephone system according to the second embodiment, and FIG. 5 is a flowchart illustrating the operation of the telephone system according to the second embodiment. In addition, the configuration of the telephone system according to the second embodiment is basically the same as that of the telephone system S according to the first embodiment, so the same members will be described using the same member numbers. Detailed description thereof is omitted.

  In the first embodiment described above, only the priority in a call sent / received via the network NT is considered. In the second embodiment described below, in addition to this, a general public line (hereinafter referred to as PSTN as appropriate) is used. Consider priorities including calls sent and received via X (abbreviated as line).

  That is, the call priority in the telephone system according to the second embodiment is such that the priority of the call received and received via the PSTN line X is the priority of the incoming call via the network NT as illustrated in FIG. And the priority of the call placed on hold by the operator of the handset device 50 is stored as priority information 85 in the non-volatile area of the memory 13A.

  Then, using the priority order information 80 to 85 illustrated in FIG. 4, call processing is executed by combining the call exchanged via the network NT and the call exchanged via the PSTN line X.

  Next, a specific example of call processing using the priority information 80 to 85 illustrated in FIG. 4 will be described with reference to FIG. Note that FIG. 5 shows the processing when there is an incoming call via the PSTN line X and when the call via the PSTN line X is terminated when a call is made with the other party “OO”. For the processing, the operation of the control units 13 and 55 and the change of the display mode in the display unit 61 are illustrated.

  That is, as illustrated in FIG. 5, when a call is being performed with a partner called “XX”, the operation information 100 indicating that the call of the partner called “XX” is in a call state. It is held in the volatile area of the memory 13A, and accordingly, the display “calling party; OO” is displayed on the display unit 61.

  If there is an incoming call via the PSTN line X in this state, a bell sound or the like indicating that the incoming call is ringed at the speaker, and the slave unit 50 is gripped correspondingly and becomes “OO”. The operator who is talking to the other party presses an end button (not shown) in the key operation unit 60.

  As a result of this operation, the call with the other party “OO” is put on hold, and based on the priority information 83 and 85 shown in FIG. 4, the operation information indicating that there is an incoming call via the PSTN line X 103 is newly stored in the volatile area of the memory 13A as the highest priority operation information, and the content of the operation state 100 is changed from “busy” to “holding” in accordance with this, and the memory 13A The display unit 61 newly displays “incoming” indicating that there is an incoming call from the PSTN line X.

  When the operator depresses a call button (not shown) in the key operation unit 60 in this state, the content of the operation state 103 is changed from “incoming call” to “busy” and then continues in the memory 13A. Further, the display unit 61 displays the time of the call via the PSTN line X and the like.

  Next, when ending the call via the PSTN line X, the operator presses an end button (not shown) in the key operation unit 60, and the call (call) via the PSTN line X is disconnected by this operation. At the same time, the operation information 103 is erased from the memory 13A. Then, based on the priority order information 83 shown in FIG. 4, the operation information 100 indicating that the call of the other party called “OO” is in the hold state has the highest priority and continues in the volatile area of the memory 13A. Along with this, a display of “holding partner: OO” is newly executed on the display unit 61.

  As described above, according to the call processing in the telephone system according to the second embodiment, in addition to the operational effects of the call processing of the telephone system S according to the first embodiment, calls sent and received via the PSTN line X The priority of the call sent / received via the incoming network NT is higher than the priority of the call sent / received via the PSTN line X, and the call sent / received via the PSTN line X Since the priority is higher than the priority of the call that is put on hold by the operation of the operator of the slave unit 50, there are a call that is sent / received via the network NT and a call that is sent / received via the PSTN line X. Even in this case, simultaneous communication can be controlled in accordance with an efficient and actual communication mode.

  The program corresponding to the flowchart shown in FIG. 2B is recorded on an information recording medium such as a flexible disk or a hard disk, or acquired and recorded via the Internet or the like, and these are stored in a general-purpose computer. It is also possible to utilize the computer as the control unit 13 or 55 according to the embodiment by reading out and executing in step.
