(Operation of this embodiment)
Next, the operation in the present embodiment will be described.

  Here, as shown in FIG. 3, the telephone information includes function key identification information “K1” indicating function key K5 from logical key information including function key identification information “K1” indicating function key K1 and group identification information “G0”. 5 logical key information up to logical key information including “K5” and group identification information “G0”, logical key information including functional key identification information “K6” indicating functional key K6 and group identification information “G1” to function. Five logical key information up to logical key information including function key identification information “K10” indicating the key K10 and group identification information “G1”, logical key including function key identification information “K6” and group identification information “G2” Information, function key identification information “K10” and group identification information “G2” including logical key information, function key identification information “K6” and group identification information. And that it comprises a five logical key information to the logical key information including the group identification information "G3" and function key identification information "K10" from the logical key information including "G3".

  Further, it is assumed that the telephone information includes selected group identification information “G1”.

  Further, in the telephone information shown in FIG. 3, all of the logical key information including the group identification information “G0” and all of the logical key information including the group identification information “G1” are stored in the logical key information of the telephone 1. It is assumed that it is stored in the unit 12.

  Further, according to the stored contents of the logical key information storage unit 12, the function keys K1 to K5 indicate the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G0”. And the function keys K6 to K10 can realize the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G1” by operating the function key. Suppose that

  Further, according to the stored contents of the logical key information storage unit 12, the display unit 13 displays the group identification information “2” out of the two group identification information included in the logical key information stored in the logical key information storage unit 12. Information indicating the group identification information “G1” that is not “G0” is displayed as indicated by reference numeral 201 in FIG. 2, and there is no display information among the logical key information stored in the logical key information storage unit 12. 2, the information indicating the logical key identification information in the logical key information corresponds to the position of the function key indicated by the functional key identification information in the logical key information. (For example, in the case of the function key K1 arranged at the upper left end among the function keys, it is the upper left end in the area where display information and function information are displayed on the display unit 13, and so on). Displayed On the other hand, for display information, as indicated by reference numeral 203 in FIG. 2, the display information corresponds to the position of the function key indicated by the function key identification information in the logical key information including the display information. It is assumed that it is displayed at the position.

  In this state, for example, when the function key K8 is operated, the telephone identification information indicating the telephone 1 stored in advance in the external storage device of the telephone 1 or the like is read and the communication of the telephone 1 is performed. The unit 14 transmits the telephone identification information and the function key identification information “K8” indicating the function key to the extension communication unit 21 of the circuit switching device 2, and the extension communication unit 21 transfers them to the management unit 24.

  The management unit 24 searches the telephone information database 23 for telephone information including the telephone identification information, and the group identification information “G1” is selected by the selected group identification information “G1” set in the searched telephone information. And the logical key information including the group identification information “G1” and the functional key identification information “K8” is retrieved, and the functional information of the retrieved logical key information is “set absence on line”. If it is information indicating “function to be performed”, the absence of the line is set according to the operation content of the telephone 1 thereafter.

  Alternatively, in such a state, for example, when the function key K8 is operated, the switching control unit 11 displays the logical key information including the function key identification information “K8” indicating the function key as the logical key information storage unit 12. And the function information included in the logical key information is read out. Then, the communication unit 14 of the telephone 1 transmits the function information to the extension communication unit 21 of the circuit switching device 2, and the extension communication unit 21 transfers these to the management unit 24.

  If the function information is information indicating “a function for setting absence on the line”, the management unit 24 sets the absence on the line according to the operation of the telephone 1 thereafter.

  FIG. 4 is a sequence diagram when the logical key information stored in the logical key information storage unit 12 of the telephone 1 is rewritten.

  By operating the switch key SK of the telephone set 1 (step S1), the switching control unit 11 reads the telephone identification information indicating the telephone set 1 stored in advance in the external storage device of the telephone set 1 and generates a switching command. Then, the communication unit 14 transmits these to the circuit switching device 2 (step S3).

  In the circuit switching device 2, the extension communication unit 21 receives the telephone identification information and the switching request command, and the management unit 24 searches the telephone information database 23 for telephone information including the received telephone identification information (step S5). The group identification information “G1” is selected by the selected group identification information “G1” set in the retrieved telephone information, and the group identification information to be selected next is the group identification information “G2”. By recognizing that there is, then all the logical key information including the group identification information “G2” is read (step S7), and the extension communication unit 21 transmits all the logical key information to the telephone 1 (step S9).

  In the telephone 1, the communication unit 14 receives the logical key information, and the switching control unit 11 converts all of the logical key information including the group identification information “G1” in the logical key information storage unit 12 with the received logical key information. Rewrite (step S11).

  Thus, in the telephone information shown in FIG. 3, all of the logical key information including the group identification information “G0” and all of the logical key information including the group identification information “G2” are the logical key information of the telephone 1. The state is stored in the storage unit 12.

  In addition, by rewriting the logical key information storage unit 12 as described above, the function keys K1 to K5 indicate the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G0”. A state in which the function keys K6 to K10 can be realized by operation, and the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G2” can be realized by operating the function key; Become.

  In other words, the telephone information includes 5 from logical key information including function key identification information “K1” and group identification information “G0” to logical key information including function key identification information “K5” and group identification information “G0”. Function key identification information “K10” indicating the function key K10 and group identification information “G1” from the logical key information including the function key identification information “K6” indicating the function key K6 and the group identification information “G1”. Including the function key identification information “K10” and the group identification information “G2” from the logical key information including the function key identification information “K6” and the group identification information “G2”. Functional key identification information “K10” from logical key information including five logical key information up to logical key information, function key identification information “K6” and group identification information “G3”. And by storing the five logical key information to the logical key information including the group identification information "G3", without switching the function of the function keys K1 to K5, it is possible to switch the functions of the function keys K6～K10.

  Further, by rewriting the logical key information storage unit 12 as described above, the display unit 13 displays the group identification information “G0 among the two pieces of group identification information included in the logical key information stored in the logical key information storage unit 12. Is displayed as indicated by reference numeral 51 in FIG. 5 (step S13), and is displayed in each logical key information stored in the logical key information storage unit 12. For information that does not have information, as indicated by reference numeral 52 in FIG. 5, information (12, 13 etc.) indicating logical key identification information in the logical key information is function key identification information in the logical key information. (Step S13), on the other hand, if there is display information, the display information includes the display information as indicated by reference numeral 53 in FIG. It is displayed at a position corresponding to the position of the function keys indicated by function key identification information in the logical key information (step S13).

  In this state, for example, when the function key K8 is operated, the telephone identification information indicating the telephone 1 is read, and the communication unit 14 of the telephone 1 reads the telephone identification information and the function key identification information “K8”. Are transmitted to the extension communication unit 21 of the circuit switching device 2, and the extension communication unit 21 transfers them to the management unit 24.

  The management unit 24 searches the telephone information database 23 for telephone information including the telephone identification information, and the group identification information “G2” is selected by the selected group identification information “G2” set in the searched telephone information. And the logical key information including the group identification information “G2” and the functional key identification information “K8” is retrieved, and the functional information of the retrieved logical key information is “set common hold”. If it is information indicating “function”, common hold is set according to the operation content of the telephone 1 thereafter.

  Alternatively, the telephone set 1 searches for logical key information including function key identification information indicating the operated function key, transmits the function information included in the logical key information to the circuit switching device 2, and manages the circuit switching device 2. If the function information is information indicating “a function for setting common hold”, the unit 24 sets common hold according to the operation content of the telephone 1 thereafter.

  The same operation is performed by the operation of the switching key SK thereafter.

  Further, instead of the telephone information of FIG. 3, for example, as shown in FIG. 6, the function key identification information “K10” and the group are obtained from the logical key information including the function key identification information “K1” and the group identification information “G1”. Functional key identification information “K10” and group identification from logical key information including ten logical key information including functional identification information “K1” and group identification information “G2” up to logical key information including identification information “G1” Functional key identification information “K10” and group identification information from logical key information including ten logical key information including information “G2”, functional key identification information “K1” and group identification information “G3” It is assumed that telephone information including 10 logical key information up to logical key information including “G3” is stored in the telephone information database 23.

  Also at this time, a display as shown in FIG. That is, the function keys K1 to K10 are in a state where the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G1” can be realized by operating the function key.

  Then, the display as shown in FIG. 7 is made by operating the switching key SK. That is, the function keys K1 to K10 can be switched to a state in which the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G2” can be realized by operating the function key.

  Then, the display as shown in FIG. 8 is performed by further operation of the switching key SK. That is, the function keys K1 to K10 can be switched to a state in which the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G3” can be realized by operating the function key.

  Then, the display as shown in FIG. 2 is performed by further operation of the switching key SK. That is, the function keys K1 to K10 can return to a state in which the function of the logical key corresponding to the function key and belonging to the group indicated by the group identification information “G1” can be realized by operating the function key. That is, the functions of all function keys can be switched.

  Further, instead of the telephone information of FIG. 3, for example, as shown in FIG. 9, the function key identification information “K7” and the group are obtained from the logical key information including the function key identification information “K1” and the group identification information “G0”. Functional key identification information “K10” and group identification from logical key information including logical key information including functional key identification information “K8” and group identification information “G1” up to logical key information including identification information “G0” Functional key identification information “K10” and group identification information from logical key information including logical key information including functional key identification information “K8” and group identification information “G2” up to logical key information including information “G1” Functional key identification information “K10” from logical key information including logical key information including functional key identification information “K8” and group identification information “G3” up to logical key information including “G2”. If the telephone information including the three logical key information up to the logical key information including the group identification information “G3” is stored in the telephone information database 23, the display as shown in FIG. Thus, the display as shown in FIG. 10 is made, and the display as shown in FIG. 11 is made by further operation of the switching key SK. That is, it is possible to switch only the functions of the function keys K8 to K10 without switching the functions of the function keys K1 to K7.

  In the above description, the function for setting absence on a line and the function for setting common hold have been described as examples. However, implementation of a similar aspect may be performed for other functions.

  Thus, according to the present embodiment, a plurality of functions can be assigned to the same function key, these functions can be switched and selected, and the selected function can be realized by operating the function key.

  FIG. 12 is a sequence diagram at the time of an incoming call according to the present embodiment.

  When there is an incoming call to one of the lines accommodated in the external line communication unit 22 of the circuit switching device 2 (step S101), the management unit 24 is the logical key information included in the telephone information from the telephone information database 23. And the logical key information in which the line identification number assigned to the incoming line is set as function information is searched (step S103), and the group identification information in the logical key information is the group identification information “G0”. It is determined whether it is the same as one of the selected group identification information. If it is determined YES (same), the management unit 24 reads the retrieved logical key information from the telephone information (step S105), and extends the logical key information and information indicating that there is an incoming call. The communication unit 21 transmits to the telephone 1 (step S107).

  In the telephone 1, the communication unit 14 receives this logical key information and the like. Then, the telephone 1 blinks the function key indicated by the function key identification information in the received logical key information (step S109). If the ringing necessity information in the logical key information indicates that ringing is necessary, the telephone 1 rings (step S109).

  When the function key and the handset 10 are operated, the communication unit 14 of the telephone 1 transmits function key identification information indicating the function key to the extension communication unit 21 of the circuit switching device 2, and this is transmitted to the extension communication unit. 21 transfers to the management unit 24. The management unit 24 determines whether or not the function key identification information in the previously transmitted logical key information and the transferred function key identification information are the same. If they are the same, the outside line communication unit 22 and the extension communication unit 21 to connect the incoming line to the telephone 1. As a result, a call can be made with the other party using the handset 10.

  When it is determined that the group identification information in the logical key information searched in step S103 is different from both the group identification information “G0” and the selected group identification information, the management unit 24 makes an inquiry to the extension communication unit 21. Then, it is determined whether or not the telephone 1 is busy (step S111).

  If it is determined YES (during a call), the management unit 24 determines whether the ringing necessity information during a call in the retrieved logical key information indicates that a ringing during a call is necessary. Is determined (step S113).

  If NO is determined in step S111 (no call is in progress) or YES is determined in step S113 (ringing is necessary during a call), the management unit 24 identifies the group in the retrieved logical key information. The selected group identification information in the telephone information is rewritten with the information (step S115), and all the logical key information including the group identification information in the retrieved logical key information is read from the telephone information and the retrieved The function key identification information is read from the logical key information (step S117), and the extension communication unit 21 transmits the logical key information, the function key identification information, and information indicating that there is an incoming call to the telephone set 1 (step S119).

  In the telephone 1, the communication unit 14 receives these logical key information and the like (step S 119), and the switching control unit 11 receives all the logical key information including the group identification information “G0” in the logical key information storage unit 12. The logical key information is rewritten with the received logical key information and a display similar to step S13 is performed (step S121).

  For example, in the logical key information before rewriting, the display information “sales department” is included in the logical key information including the function key identification information of the function key operated when connecting to the line during the call. When the rewritten logical key information includes the display information “management unit”, the “sales unit” displayed on the display unit 13 is switched to the “management unit”.

  Then, the telephone 1 blinks the function key indicated by the received function key identification information (step S123). Note that the telephone 1 blinks the function key regardless of whether the function key is operated when connected to the line during a call.

  Further, in the logical key information storage unit 12, when the ringing necessity information in the logical key information including the function key identification information indicates that ringing is necessary, the telephone 1 rings (step S123). Then, by the operation of the function keys, the line being talked is put on hold while maintaining the connection. Then, the incoming line is newly connected to the telephone 1 so that a call can be made. That is, the function key can execute the function corresponding to the rewritten logical key information at the time of operation while maintaining the connection to the line during the call. When the function key is not operated, the line being talked is not put on hold and the call can be continued.

  If it is determined NO in step S113 (no ringing is necessary during a call), the management unit 24 indicates that the voice setting success / failure information in the retrieved logical key information indicates that voice setting has been made. It is determined whether or not (step S201).

  If it is determined NO (no voice setting is made), the management unit 24 causes the external line communication unit 22 to disconnect the communication (step S203). At this time, the logical key information is not rewritten and the display is not changed as in step S121.

  On the other hand, if it is determined as YES (voice setting is made) in step S201, the management unit 24 determines whether or not the recording necessity information in the telephone information indicates that the other party's voice recording is necessary. Is determined (step S205).

  If it is determined NO (the other party's voice recording is not required), the management unit 24 controls an unattended message sending unit (not shown) to send a predetermined answering message to the incoming line (step S207). ). At this time, the logical key information is not rewritten and the display is not changed as in step S121.

  On the other hand, if it is determined YES in step S205 (the other party's voice recording is necessary), the management unit 24 controls a recording processing unit (not shown) to record the other party's voice from the incoming line (step S205). S209).

  Then, after step S209, when the management unit 24 is notified from the extension communication unit 21 that the telephone 1 has ended, the voice reproduction information such as “BOX” described with reference to FIG. Logical key information that is set as information and does not include the group identification information “G0” and the selected group identification information is searched from the telephone information (step S301).

  When the corresponding logical key information is retrieved, the selected group identification information of the telephone information is rewritten with the group identification information in the retrieved logical key information (step S303), and the retrieved logical key information All of the logical key information including the group identification information is read from the telephone information, and the function key identification information is read from the searched logical key information (step S305). The extension communication unit 21 transmits the logical key information, the function key identification information, and the information indicating that the recording has been performed to the telephone 1 when the communication is cut off on the notified line (step S307). .

  In the telephone 1, the communication unit 14 receives these logical key information and the like, and the switching control unit 11 receives all the logical key information other than the logical key information including the group identification information “G0” in the logical key information storage unit 12. The received logical key information is rewritten and the same display as in step S13 is performed (step S309).

  Then, in the logical key information storage unit 12, the telephone 1 indicates that the recording notification blinking necessity information in the received logical key information including the relevant function key identification information indicates that the function key needs to be blinked. In this case, the function key indicated by the function key identification information is blinked (step S311).

  Note that the search in step S301 is performed after the end of the call, and NO is determined in the previous step S113 (no ringing during the call is necessary). In such a case, the function key flashes in step S311. This is because it is preferable to prevent the call from being disturbed.

  When the blinking function key and the handset 10 are operated, the communication unit 14 of the telephone 1 transmits function key identification information indicating the function key to the extension communication unit 21 of the circuit switching device 2. Is transferred to the management unit 24 by the extension communication unit 21. The management unit 24 determines whether or not the previously transmitted function key identification information and the transferred function key identification information are the same, and if they are the same, controls the recording processing unit and the extension communication unit 21 (not shown). The recorded voice is transmitted to the telephone 1, and the telephone 1 reproduces it. Therefore, the sound recorded using the handset 10 can be heard.

  As described above, according to the present embodiment, the logical key information in which the line identification number of the line is set is retrieved from the telephone information by the incoming call to the line (S103), and is included in the logical key information. When the group identification information is group identification information indicating a group of functions that are not currently realizable, the telephone is set so that all of the logical key information including the group identification information becomes logical key information corresponding to the functions that are currently realizable. The information is rewritten (S115), and the logical key information including the group identification information and the function key identification information set in the retrieved logical key information are transmitted to the telephone (S119), and the transmitted function key identification information is transmitted. When a telephone is connected to the corresponding line by operating the function key corresponding to, multiple times assigned to one function key of the telephone It is possible to connect the telephone to the line by operating the function keys even when there is an incoming call to any of the.

  Also, when the other party's voice is recorded by the circuit switching device, the logical key information corresponding to the function that cannot be realized at present and having the voice reproduction information indicating the function of reproducing the recorded other party's voice is searched. (S301) When the corresponding logical key information is searched, the logical key information corresponding to the function that is not currently realizable, including the searched logical key information, becomes the logical key information corresponding to the function that is currently realizable. The telephone information is rewritten as described above (S303), and the logical key information corresponding to the currently realizable function and the functional key identification information set in the searched logical key information are transmitted to the telephone (S307). The voice recorded by the circuit switching device is transmitted to the telephone by the operation of the function key corresponding to the function key identification information, and the telephone reproduces the voice. A function not possible standing realize "play automated recorded partner voice" as automatically currently feasible, it can reproduce the sound by operating the function keys.

  Note that the voice recording information of the present embodiment is set as setting information according to a desired function, and processing is performed as when the other party's voice is reproduced, so that even if the function is not currently realizable, It can be realized by switching to a function that can be realized at present.
