  In step S170, database access control unit 76 receives information requesting an incoming call.

  In step S172, the identification unit 702 extracts the telephone number of the called IP telephone terminal from the information requesting the incoming call. When the number is extracted, the identification unit 702 determines whether or not the calling-side user has requested an incoming call in order to register the degree of incoming call rejection based on the telephone number. If the telephone number is a telephone number previously known to the user in order to register the degree of rejection of incoming calls, the identification unit 702 allows the calling user to receive an incoming call in order to register the degree of rejection of incoming calls. Judge that requested. If it is determined that the calling user has requested an incoming call to register the degree of incoming call rejection (YES in step S172), the process proceeds to step S174. If not (NO in step S172), the process proceeds to step S176.

  In step S174, the telephone exchange according to the present embodiment performs a process for registering the degree of incoming call rejection. This processing corresponds to processing from step S210 to step S220 described later.

  In step S176, the identification unit 702 extracts sub-number information from information requesting an incoming call. In the case of the present embodiment, among numbers communicated as the telephone number of the IP telephone terminal, a number excluding a number essential for specifying the called party is referred to as a “sub number”. The sub number extracted in this step is used as importance information. When the sub-number information is extracted, the database access management unit 76 requests access permission from the database unit 52. When access permission is obtained from the database unit 52, the database access management unit 76 transmits importance level information indicated by the sub number and other information related to the IP telephone terminal on the calling side to the database unit 52.

  In step S178, the table search unit 82 of the database unit 52 refers to the call history information included in the subscriber table 842. When the information is referred to, the table search unit 82 counts the number of times that a call that is common between the calling IP telephone terminal and the called IP telephone terminal is repeated within a predetermined period. When the number of times is counted, the table search unit 82 determines whether the number of times exceeds a threshold value. If it is determined that the number of times exceeds the threshold value (YES in step S178), the process proceeds to step S180. If not (NO in step S178), the process proceeds to step 182.

  In step S180, the SIP access control unit 70 repeats the call that is common to the calling IP phone terminal and the called IP phone terminal within a predetermined period in accordance with the control of the table search unit 82. A signal indicating that the number of times exceeds the threshold value is transmitted to the database access control unit 76.

  In step S182, table search unit 82 searches for information corresponding to the telephone number extracted in step S172 from the degree information stored in reception filter table 846. If there is information to the extent corresponding to the telephone number extracted in step S 172, the SIP access control unit 70 transmits the information to the database access control unit 76 according to the control of the table search unit 82.

  In step S184, identification control unit 750 controls database access control unit 76 to receive the SSID of the access point that relays communication with the called IP telephone terminal from the called IP telephone terminal. . For this purpose, the database access control unit 76 transmits a signal for requesting transmission of the SSID information to the called IP telephone terminal. When the SSID information is returned, the identification control unit 750 identifies the type of the location of the called IP telephone terminal based on the SSID. When the information of the SSID is stored in the public database 848 and the information of the SSID is associated with the information “call allowed area”, the identification control unit 750 determines the location of the called IP telephone terminal. It is determined that the type is “call-permitted area”. When the SSID information is associated with the information “call suppression area” or when the public database 848 does not include the SSID information, the identification control unit 750 receives the IP telephone terminal on the called side. It is determined that the type of the location is “call suppression area”. However, when the SSID information is not returned, the identification control unit 750 determines that the location type of the called IP telephone terminal is “unknown location”. The selection unit 704 selects processing corresponding to the combination based on the importance level information, the degree information, and the type of location of the destination IP telephone terminal. When the SIP access control unit 70 does not transmit a signal in step S180, the general selection unit 712 performs this selection. When the SIP access control unit 70 is transmitting a signal, the special selection unit 714 performs this selection. In the case of the present embodiment, the general selection unit 712 and the special selection unit 714 perform this selection based on the processing method database that is a part of the selection unit 704.

Note that, as described above, the special selection unit 704 has importance information indicating importance higher than the importance information included in the call information, degree information associated with the called telephone, and the incoming IP telephone. Select the process according to the combination of the terminal location type. The degree of importance that is shown is not particularly limited. For example, the degree of importance may correspond to the number of times that a call that is common between the calling IP telephone terminal and the called IP telephone terminal is repeated within a predetermined period. The height may be predetermined. In the case of the present embodiment, it is assumed that the degree of importance is predetermined.

  In step S186, call control unit 742 determines whether the process selected by selection unit 704 is a standard incoming call. In the present embodiment, “standard incoming call” means a process normally performed for starting a call to an incoming IP telephone terminal. If it is determined that the incoming call is standard (YES in step S186), the process proceeds to step S188. If not (NO in step S186), the process proceeds to step S190.

  In step S188, call control unit 742 performs standard incoming call. Since processing for standard incoming calls is well known, detailed description thereof will not be repeated here.

  In step S190, call control unit 742 determines whether the process selected by selection unit 704 is a manner mode incoming call or not. In this embodiment, “silent mode incoming call” means a process for calling a user in the manner mode in addition to a process normally performed for starting a call to the called IP telephone terminal. Means. If it is determined that the manner mode is received (YES in step S190), the process proceeds to step S192. If not (NO in step S190), the process proceeds to step S194.

  In step S192, call control unit 742 performs a manner mode incoming call. The only difference between the process for the manner mode incoming call and the process for the standard incoming call is that the sub-number of the called IP telephone terminal represents a command for calling the user in the manner mode. The called IP telephone terminal calls the user in the manner mode if the sub-number represents a command for calling the user in the manner mode.

  In step S194, call control unit 742 determines whether the process selected by selection unit 704 is an alternative incoming call. In the present embodiment, “alternative incoming call” means a process for requesting an incoming call to an alternative telephone when the called IP telephone terminal does not accept the incoming call or when the terminal cannot receive the incoming call. . After requesting an incoming call to an alternative telephone, the calling side user requests a message to the alternative telephone user in response to the incoming call or calls the user of the incoming IP telephone terminal Thus, some information can be transmitted to the user of the called IP telephone terminal. It may be possible to shorten the time until the information is transmitted to the user of the called IP telephone terminal. If it is determined that the incoming call is an alternative incoming call (YES in step S194), the process proceeds to step S196. If not (NO in step S194), the process proceeds to step S198.

  In step S196, the telephone exchange according to the present embodiment performs processing for alternate incoming calls in cooperation. This processing corresponds to processing from step S230 to step S260 described later.

  In step S198, storage unit 84 of database unit 52 stores the information received in step S170 as part of subscriber table 842. As a result, the call history information is updated.

  In step S200, the telephone exchange according to the present embodiment performs an answering machine process. In the present embodiment, “answering process” refers to the user of the called IP phone terminal when the location of the called IP phone terminal is unknown or the terminal is not turned on. This means the process of storing the message. Since the specific contents of the absence recording process are well known, detailed description thereof will not be repeated here.

  Referring to FIG. 7, the program executed by the telephone exchange according to the present embodiment executes the following control regarding registration of the degree of incoming call rejection.

  In step S210, call control unit 742 starts a session with the IP telephone terminal that transmitted the information in step S170.

  In step S212, the database access control unit 76 transmits information that prompts input of the degree of incoming call rejection in accordance with the control of the call control unit 742. This information is displayed as a message that prompts the IP telephone terminal that transmitted the information in step S170 to input the degree of call rejection.

  In step S214, the database access control unit 76 receives the degree information. This information is input by the user of the IP telephone terminal and transmitted by the IP telephone terminal. When the degree information is received, the storage unit 84 stores the degree information as a part of the reception filter table 846.

  In step S 216, database access control unit 76 transmits information for prompting selection of a contact method according to the control of call control unit 742. This information is displayed as a message prompting the user to select a contact method at the IP telephone terminal that transmitted the information at step S170. In the case of the present embodiment, the user can select whether he / she wants to be contacted to a temporary contact address or to be contacted based on information registered in the storage unit 84 in advance. .

  In step S218, call control unit 742 receives information representing a contact method. This information is selected by the user of the IP telephone terminal and transmitted by the IP telephone terminal. If the user wishes to be contacted to a temporary contact, this information includes information representing the telephone number of the temporary contact. When information representing the contact method is received, the storage unit 84 stores information representing the telephone number of the temporary contact as part of the subscriber table 842.

In step S220, call control unit 742 ends the session.
With reference to FIG. 8 and FIG. 9, the program executed by the telephone exchange according to the present embodiment executes the following control with respect to the alternative incoming call.

  In step S230, the table search unit 82 refers to the subscriber table 842 for the telephone numbers extracted in step S172. This telephone number is information received from the database access control unit 76 via the SIP access control unit 80.

  In step S232, table search unit 82 determines whether or not temporary contact information is included in subscriber table 842 for the telephone number extracted in step S172. If it is determined that temporary contact information is included (YES in step S232), the process proceeds to step S234. If not (NO in step S232), the process proceeds to step S236.

  In step S 234, the SIP access control unit 80 transmits the temporary contact information stored in the subscriber table 842 to the database access control unit 76. This information is information associated with the telephone number extracted in step S172. The establishment control unit 752 establishes a session with the alternative telephone represented by the information as the called party. Thereafter, the alternative control unit 740 ends the session with the end of the call. In this step, the process from the establishment to the end of the session is the same as that generally performed when a call is made. Therefore, detailed description thereof will not be repeated here.

  In step S236, the SIP access control unit 80 transmits a signal to the database control unit 74. The signal indicates that the temporary contact information is not included in the subscriber table 842 for the telephone number extracted in step S172. When the database control unit 74 receives the signal, the identification control unit 750 accesses the database so that the SSID of the access point that relays communication with the called IP phone terminal is received from the called IP phone terminal. The controller 76 is controlled. For this purpose, the database access control unit 76 transmits a signal for requesting transmission of the SSID information to the called IP telephone terminal.

  In step S238, identification control unit 750 determines whether or not database access control unit 76 has received the SSID of the access point that relays communication with the called IP telephone terminal. If it is determined that database access control unit 76 has received the SSID (YES in step S238), the process proceeds to step S240. If not (NO in step S238), the process proceeds to step S242.

  In step S240, the database access control unit 76 transmits the SSID information received by the database access control unit 76 to the SIP access control unit 80 in accordance with the control of the identification control unit 750. When the SIP access control unit 80 receives the information, the table search unit 82 is associated with the telephone number extracted in step S172 out of the SSIDs stored in the subscriber table 842, and the database access control unit 76. Search for the one that matches the SSID indicated by the received information.

  In step S242, detection unit 754 detects the current time and other times. When the time is detected, the database access control unit 76 transmits information on the time to the SIP access control unit 80. When the time information is transmitted, the table search unit 82 searches the information stored in the subscriber table 842 for the telephone number associated with the telephone number extracted in step S172 and the time. .

  In step S244, the table search unit 82 determines that the telephone number associated with the telephone number extracted in step S172 and the time detected in step S242 is a subscriber based on the search result in step S242. It is determined whether it is included in the table 842. If it is determined that such a telephone number is included in subscriber table 842 (YES in step S244), the process proceeds to step S246. If not (NO in step S244), the process proceeds to step S248.

  In step S246, the SIP access control unit 80 transmits information on the telephone number searched in step S242 to the database access control unit 76. The incoming call control unit 756 establishes a session with the alternative telephone indicated by the information as the incoming call side. Thereafter, the incoming call control unit 756 ends the session as the call ends. In this step, the process from the establishment to the end of the session is the same as that generally performed when a call is made. Therefore, detailed description thereof will not be repeated here.

  In step S248, table search unit 82 reads the telephone number included in subscriber table 842 as the final contact address from storage unit 84. When the telephone number is read, the SIP access control unit 80 transmits information on the telephone number included in the subscriber table 842 as the final contact address to the database access control unit 76. The establishment control unit 756 establishes a session with the alternative telephone indicated by the information as the called party. Thereafter, the establishment control unit 756 ends the session with the end of the call. In this step, the process from the establishment to the end of the session is the same as that generally performed when a call is made. Therefore, detailed description thereof will not be repeated here.

  In step S250, the table search unit 82 associates one of the SSIDs stored in the subscriber table 842 with the telephone number extracted in step S172, and the database access control unit 76 performs the process in step S236. It is determined whether or not it matches the SSID indicated by the received information. If it is determined that any of the SSIDs stored in subscriber table 842 matches such an SSID (YES in step S250), the process proceeds to step S252. If not (NO in step S250), the process proceeds to step S254.

  In step S252, the SIP access control unit 80 stores information on the telephone number corresponding to the SSID indicated by the information received by the database access control unit 76 in step S236 among the telephone numbers stored in the subscriber table 842. It transmits to the access control part 76. The establishment control unit 756 establishes a session with the alternative telephone indicated by the information as the called party. Thereafter, the establishment control unit 756 ends the session with the end of the call. In this step, the process from the establishment to the end of the session is the same as that generally performed when a call is made. Therefore, detailed description thereof will not be repeated here.

  In step S254, the table search unit 82 searches for the SSID indicated by the information included in the public table 848 that matches the SSID indicated by the information received by the database access control unit 76 in step S236.

  In step S256, based on the result of the search in step S254, the table search unit 82 includes the SSID indicated by the information received by the database access control unit 76 in step S236, among the SSIDs indicated by the information included in the public table 848. Determine if there is a match. If it is determined that there is such an SSID (YES in step S256), the process proceeds to step S258. If not (NO in step S256), the process proceeds to step S260.

  In step S258, the SIP access control unit 80 transmits information on the telephone number corresponding to the SSID indicated by the information received in step S236 among the telephone numbers included in the public table 848 to the database access control unit 76. . The establishment control unit 756 establishes a session with the alternative telephone indicated by the information as the called party. Thereafter, the establishment control unit 756 ends the session with the end of the call. In this step, the process from the establishment to the end of the session is the same as that generally performed when a call is made. Therefore, detailed description thereof will not be repeated here.

  In step S260, table search unit 82 reads the telephone number included in subscriber table 842 as the final contact address from storage unit 84. When the telephone number is read, the SIP access control unit 80 transmits information on the telephone number included in the subscriber table 842 as the final contact address to the database access control unit 76. The establishment control unit 756 establishes a session with the alternative telephone indicated by the information as the called party. Thereafter, the establishment control unit 756 ends the session with the end of the call. In this step, the process from the establishment to the end of the session is the same as that generally performed when a call is made. Therefore, detailed description thereof will not be repeated here.

  Referring to FIG. 10, the program executed by IP telephone terminal 62 according to the present embodiment executes the following control with respect to the manner mode incoming call.

  In step S280, WiFi communication module 104 of IP telephone terminal 62 receives information for requesting session establishment.

  In step S282, CPU 114 extracts the sub number of the telephone number of IP telephone terminal 62 itself from the information requesting establishment of the session.

In step S284, CPU 114 establishes a session.
In step S286, CPU 114 determines whether or not to make a manner mode call. In the case of the present embodiment, CPU 114 has a case where the sub-number extracted in step S282 is a number for making a manner mode call, and a case where information stored in memory 102 represents a manner mode call. Then, it is determined that the manner mode is received. If it is determined that the manner mode call is to be made (YES in step S286), the process proceeds to step S288. If not (NO in step S286), the process proceeds to step S290.

  In step S288, CPU 114 drives vibrator 116. In step S290, CPU 114 controls sound processing unit 108. The audio processing unit 108 outputs an incoming call sound signal to the jack 112. Headset 120 sounds an incoming call based on the signal output from jack 112.

  In step S292, CPU 114 controls WiFi communication module 104 and audio processing unit 108 in response to operation input unit 106 being operated to respond to an incoming call. Thereby, the WiFi communication module 104 communicates an audio signal. The sound processing unit 108 converts the signal output from the CPU 114 into a signal that can be converted into sound by the headset 120, or converts the sound signal output from the headset 120 into a signal that can be processed by the CPU 108.

  In step S294, CPU 114 determines whether to end the call based on the signal received by WiFi communication module 104 or the operation on operation input unit 106. If it is determined that the call is to be terminated (YES in step S294), the process proceeds to step S296. Otherwise (NO in step S294), the process proceeds to step S292.

In step S296, CPU 114 performs processing for ending the session.
The operation of the telephone exchange system based on the above structure and flowchart will be described.

[Register importance]
The database access control unit 76 receives information requesting an incoming call (step S170). In this case, it is assumed that the IP telephone terminal 64 is a calling telephone.

  In this embodiment, this information is communicated as a packet. FIG. 11 is a diagram showing a packet format in the present embodiment. In this embodiment, all packets communicate information according to SIP and SDP (Session Description Protocol) or RTP (Real-time Transport Protocol). When communicating information according to SIP or SDP, these packets all include a data link layer header 180, an IP header 182, a UDP header 184, and SIP data 186. The data link layer header 180 is data for communicating a packet through a LAN interface device in a LAN or a WAN (Wide Area Network). The IP header 182 is data defining a data transmission destination. The UDP header 184 is data defining a communication port. The SIP data 186 is various data according to SIP and SDP. Note that the format of a packet in the case of communicating information according to RTP is well known, and therefore the format is not described here.

  The identification unit 702 extracts the telephone number of the called IP telephone terminal from the information requesting the incoming call. When the number is extracted, based on the telephone number, the identification unit 702 determines whether or not the calling-side user has requested an incoming call in order to register the degree of incoming call rejection (step S172). . In this case, if an incoming call is requested to register the degree of call rejection (YES in step S172), call control unit 742 establishes a session with the IP telephone terminal that transmitted the information in step S170. Start (step S210).

  When the session is started, the database access control unit 76 transmits information that prompts input of the degree of incoming call rejection (step S212). When the IP telephone terminal 64 receives this information, it displays a message prompting the user to input the degree of incoming call rejection.

  The user of IP telephone terminal 64 inputs the degree of incoming call rejection to IP telephone terminal 64. The IP telephone terminal 64 transmits degree information to the telephone exchange. The database access control unit 76 receives the degree information. When the degree information is received, the storage unit 84 stores the degree information as a part of the reception filter table 846 (step S214).

  When the degree information is stored, the database access control unit 76 transmits information for prompting selection of a contact method (step S216). When receiving this information, IP telephone terminal 64 displays a message prompting the user to select a contact method. The user of the IP telephone terminal 64 inputs information indicating the selection result to the IP telephone terminal 64. IP telephone terminal 64 transmits the information to the telephone exchange.

  Call control unit 742 receives the information. If the information representing the telephone number of the temporary contact is included in the information, the storage unit 84 stores information representing the telephone number of the temporary contact as part of the subscriber table 842 (step S218). .

Thereafter, the call control unit 742 ends the session (step S220).
[The sender's initial importance information is “slightly low”, the called party's importance is “Respond only in case of emergency”, the temporary contact is registered, and the incoming IP phone terminal When the location is unknown]
Assume that a call is made with IP telephone terminal 64 as the calling party and IP telephone terminal 62 as the called party. Through the processing in step S170, the identification unit 702 determines whether or not the calling user has requested an incoming call in order to register the degree of call rejection based on the telephone number (step S172). In this case, if an incoming call is requested for a call in this case (NO in step S172), identification unit 702 extracts sub-number information from the information requesting the incoming call. When the sub-number information is extracted, the storage unit 84 stores information on the calling IP phone terminal as a part of the outgoing filter table 844 (step S176).

  When information related to the IP telephone terminal on the calling side is stored, the table search unit 82 repeats the call that is common to the IP telephone terminal on the calling side and the IP telephone terminal on the called side within a predetermined period. It is determined whether or not the number of times exceeds the threshold (step S178). In this case, if the number of times does not exceed the threshold (NO in step S178), table search unit 82 searches reception filter table 846 for information corresponding to the telephone number extracted in step S172. In this case, since the degree information indicating that the response is made only in an emergency is stored, the SIP access control unit 70 transmits the information to the database access control unit 76 (step S182).

  When the degree information is transmitted, the general selection unit 712 determines the importance level information, the degree information, and the destination side information based on the importance level information, the degree information, the type of the location of the destination IP telephone terminal, and the processing method database. A process corresponding to the combination with the type of location of the IP telephone terminal is selected (step S184).

  FIG. 12 is a diagram showing the contents of the processing method database in the present embodiment. In FIG. 12, the location type is referred to as “presence”.

  In this case, since the importance level information on the transmitting side is “slightly low”, the importance level on the called side is “response only in an emergency”, and the location of the IP telephone terminal 62 on the receiving side is unknown, the processing to be selected Is “answering process”.

  When the process is selected, the call control unit 742 determines whether the process selected by the selection unit 704 is a standard incoming call (step S186). In this case, since the selected process is not a standard incoming call (NO in step S186), call control unit 742 determines whether the process selected by selecting unit 704 is a manner mode incoming call (step S190). In this case, since the selected process is not a manner mode call (NO in step S190), call control unit 742 determines whether or not the process selected by selection unit 704 is an alternative call (step S194). In this case, since the selected process is not an alternative incoming call (NO in step S194), storage unit 84 of database unit 52 updates the call history information (step S198). When the information is updated, the telephone exchange performs an answering machine process (step S200).

[Initial importance on the sending side is “slightly important”, importance on the called side is “responds only in case of emergency”, temporary contact is not registered, and the IP phone terminal on the called side is not registered. When the SSID of the access point that is communicating with the type of location "call suppression area" is known]
Assume that a call is made with IP telephone terminal 64 as the calling party and IP telephone terminal 62 as the called party. Through the processes from step S170 to step S182, the general selection unit 712 selects a process (step S184).

  In this case, the importance level information on the transmission side is “slightly important”, the importance level on the called side is “respond only in an emergency”, and the type of the location of the IP phone terminal 62 on the receiving side is “call suppression area”. Therefore, the selected process is “silent mode incoming call”.

  When the process is selected, the call control unit 742 determines whether the process selected by the selection unit 704 is a standard incoming call (step S186). In this case, since the selected process is not a standard incoming call (NO in step S186), call control unit 742 determines whether the process selected by selecting unit 704 is a manner mode incoming call (step S190). In this case, since the selected process is a manner mode incoming call (YES in step S190), call control unit 742 performs a manner mode incoming call (step S192).

  On the other hand, the WiFi communication module 104 of the IP telephone terminal 62 receives information for requesting session establishment (step S280).

  When the information is received, CPU 114 extracts the sub number of the telephone number of IP telephone terminal 62 itself from the information requesting establishment of the session (step S282).

  When the sub number is extracted, the CPU 114 establishes a session (step S284).

  When the session is established, the CPU 114 determines whether or not to make a manner mode call (step S286). In this case, since it is determined that the manner mode call is received (YES in step S286), CPU 114 drives vibrator 116 in step S288 (step S288).

  When the vibrator 116 is driven, the CPU 114 controls the WiFi communication module 104 and the sound processing unit 108. Thereby, the WiFi communication module 104 communicates an audio signal. The audio processing unit 108 converts the signal output from the CPU 114 into a signal that the headset 120 can convert into audio, or converts the audio signal output from the headset 120 into a signal that can be processed by the CPU 108 (step S292).

  Thereafter, the CPU 114 determines whether or not to end the call based on the signal received by the WiFi communication module 104 or the operation on the operation input unit 106 (step S294). Since it is initially determined that the call is continued (NO in step S294), the process in step S292 and the process in step S294 are repeated, but it is determined that the call is finally ended (NO in step S294). ) The CPU 114 performs a process for terminating the session (step S296).

[The initial importance on the sending side is “important”, the importance on the called side is “rejected”, the temporary contact is not registered, and the schedule registered in the database unit 52 corresponds to the current time When there is nothing to do and the location of the called IP phone terminal is unknown]
Assume that a call is made with IP telephone terminal 64 as the calling party and IP telephone terminal 62 as the called party. Through the processes from step S170 to step S182, the general selection unit 712 selects a process (step S184).

  In this case, since the importance level information on the transmitting side is “important”, the importance level on the called side is “rejected”, and the type of the location of the IP telephone terminal 62 on the receiving side is “unknown”, the processing to be selected Is an “alternative call”.

  When the process is selected, the call control unit 742 determines whether the process selected by the selection unit 704 is a standard incoming call (step S186). In this case, since the selected process is not a standard incoming call (NO in step S186), call control unit 742 determines whether the process selected by selecting unit 704 is a manner mode incoming call (step S190). In this case, since the selected process is not a manner mode call (NO in step S190), call control unit 742 determines whether or not the process selected by selection unit 704 is an alternative call (step S194). In this case, since the selected process is a substitute incoming call (YES in step S194), table search unit 82 refers to subscriber table 842 for IP telephone terminal 62 (step S230).

  When the subscriber table 842 is referred to, the table search unit 82 determines whether or not the temporary contact information is included in the subscriber table 842 for the telephone number extracted in step S172 (step S172). S232). In this case, if temporary contact information is not included (NO in step S232), database access control unit 76 requests transmission of SSID information of access point 60 according to the control of identification control unit 750. A signal to be transmitted is transmitted to the IP telephone terminal 62 (step S236).

  When the signal is transmitted, the identification control unit 750 determines whether or not the SSID information of the access point 60 has been received (step S238). In this case, if information on the SSID cannot be received (NO in step S238), detection unit 754 detects the current time and other times. When the time is detected, the table search unit 82 searches the telephone number associated with the telephone number extracted in step S172 and the time among the information stored in the subscriber table 842 (step S172). S242).

  FIG. 13 is a diagram showing information about the user of the IP telephone terminal 62 among the information stored in the subscriber table 842. In this case, it is assumed that information “Friday, December 8, 16:45” is obtained as information on the current time and other times.

  When the search is completed, the table search unit 82 determines that the telephone number associated with the telephone number extracted in step S172 and the time detected in step S242 is a subscriber based on the search result in step S242. It is determined whether or not it is included in the table 842 (step S244). If the obtained information is, for example, information “Friday, December 8, 16:10”, information on the telephone number “06-62...” Corresponding to the information is included in the subscriber table 842. In this case, since such telephone number information is not included (NO in step S244), the table search unit 82 sets “072−” of “final contact” shown in FIG. .. ”Is read from the storage unit 84. When the telephone number is read, the establishment control unit 756 establishes a session with the alternative telephone indicated by the information as the called party. Thereafter, the establishment control unit 756 ends the session with the end of the call (step S248).

  As described above, the telephone exchange according to the present embodiment selects a process for a call based on the importance information on the calling side and the degree information on the called side. Thereby, it is possible to flexibly start or not start a call in accordance with the convenience of the calling user and the convenience of the called user. The telephone exchange according to the present embodiment considers not only the convenience of the user on the calling side but also the convenience of the user on the called side when it is necessary to urgently request the incoming call. As a result, when it is necessary to urgently request an incoming call, it is possible to provide a telephone exchange that can effectively prompt a call according to the circumstances of the calling side and the called side.

  Also, the telephone exchange according to the present embodiment establishes communication with an alternative telephone depending on the convenience of the called party. As a result, even if the other party is not the one who requested the incoming call, it is possible to make a call with the other party or to use the telephone other than the one that requested the incoming call. This increases the possibility that information can be transmitted quickly. Up to now, when the called party is unknown, there is no countermeasure other than making a call to the contact information known to the user of the calling party or leaving a message by answering. However, since the telephone exchange according to the present embodiment establishes communication with the alternative telephone, the calling side user can make a call with an appropriate contact without knowing the contact, so that the call Information can be transmitted to the user. In addition, the time until information is transmitted to the called user can be significantly reduced as compared with the case where calls are sequentially made to contacts known by the calling user.

  In addition, the telephone exchange according to the present embodiment selects an alternative telephone based on the identification information of the communication apparatus that relays communication with the called telephone. This increases the possibility that a call can be made with the user of the called telephone as compared to when calling a single alternative telephone.

  In addition, the telephone exchange according to the present embodiment detects a time when a call is made, and selects an alternative telephone based on a previously registered schedule and the time. This increases the possibility that a call can be made with the user of the called telephone even if the location of the called telephone is unknown.

  Further, the telephone exchange according to the present embodiment selects a telephone set designated in advance by the user of the called telephone as an alternative telephone. This increases the possibility that information can be quickly transmitted to the user of the called telephone through a message or other means.

  In addition, when the frequency of outgoing calls exceeds a threshold, the telephone exchange according to the present embodiment regards the outgoing call as having an importance level higher than the importance level represented by the importance level information included in the outgoing call information, and performs processing. select. As a result, even when the calling user mistakenly designates a low importance level, the process can be selected based on the appropriate importance level.

  In the first modification, the telephone exchange may communicate with a mobile phone or a PHS (Personal Handyphone System) instead of the IP telephone terminal. In this case, instead of the SSID, identification information for identifying the base station may be used.

  In the second modification, the processing method database may be set for each subscriber. In this case, the processing method database is searched by the table search unit 82 as a part of the subscriber table 842. Information indicating processing obtained as a result of the search may be transmitted by the SIP access control unit 80 under the control of the table search unit 82 and referred to by the general selection unit 712 or the special selection unit 714. In this case, the contents of the processing method database may be set by the user. When the contents of the processing method database are set by the user, the importance level information and the degree information may be selected from any of several types of preset information. In this case, the importance level information and the degree information set in advance may correspond to a specific situation where the user is placed. Examples of such importance information include “from senior management”, “from boss”, “from department”, “emergency”, “from friends”, “from school / nursery”, or “child accident / Examples of degree information include “Reject”, “Respond to call from boss”, “In meeting”, “Presence”, “In meeting”, “Negotiating”, “ Includes “During normal work”, “Out of office”, “Respond only in case of emergency”, “Random”, “Private time”, etc. FIG. 14 is a conceptual diagram showing elements for selecting a process by the telephone exchange in such a case. By selecting the importance information and degree information in this way, the degree information is set to “Respond to a call from the boss”, and when the boss makes a call with the importance information set to “From the boss”, the business trip destination During important meetings, you can receive important telephone instructions from your boss and avoid worrying about calls from other people.

  Incidentally, in this case, degree information may be set for each telephone on the calling side. When degree information is set for each telephone on the calling side, the general selection unit 712 or the special selection unit 714 selects a process in consideration of the data table on the calling side in addition to the degree information itself. A processing method database is stored for each combination of subscriber and telephone number of the calling telephone. In this way, by setting the degree information for each caller's phone, if it is set to “answering process” for a specific phone regardless of the importance information, the call from that phone is set. Is effectively rejected. Of course, it may be notified to the telephone on the calling side that the incoming call has been rejected, as in the case of a general incoming call rejection service.

  When the processing method database is searched as a part of the subscriber table 842 by the table search unit 82, the information relay unit 50 and the database unit 52 may be realized by computer hardware independent of each other. In this case, the computer hardware constitutes a set of telephone exchange systems. In these telephone exchange systems, the database unit 52 is realized as a single database device. As is apparent from FIG. 1, the database unit 52 includes a SIP access control unit 80 that communicates with the information relay unit 50, a storage unit 84, and a table search unit 82 that controls the SIP access control unit 80. When the SIP access control unit 80 receives call information via the information relay unit 50, the table search unit 82 controls the SIP access control unit 80 to transmit information indicating processing to the information relay unit 50. The information relay unit 50 is also realized as a single database device. The information relay unit 50 includes a database access control unit 76 that communicates with a plurality of telephones via the IP network 56 and communicates with the database unit 52, a SIP message processing unit 70, and a session processing unit 74. When the database access control unit 76 receives the call information, the SIP message processing unit 70 controls the database access control unit 76 to transmit the call information to the database unit 52. When the database access control unit 76 receives information indicating the process from the database unit 52, the session processing unit 74 transmits the information to the IP telephone terminal that transmitted the call information according to the process indicated by the information. The access control unit 76 is controlled. In this case, the SIP message processing unit 70 and the session processing unit 74 constitute one control block that controls the database access control unit 76.

  In the third modification, the processing method database may not include location type information. In this case, the selection unit 704 selects a process corresponding to the combination of the degree information and the importance information. The type of location is not considered.

  In the fourth modification, the information in the subscriber table 842 may be linked with a schedule registration service for the subscriber. In this case, the user registers his / her schedule in the SIP server which is the telephone exchange according to the present embodiment so that the user can refer to the user via the IP network 56. The SIP server, which is a telephone exchange according to the present embodiment, uses the schedule information for the above-described alternative incoming call.

  In the fifth modification, instead of the SIP access control unit 70 transmitting the degree information in step S182, the called IP telephone terminal directly transmits the degree information to the database access control unit 76. May be. In this case, the identification control unit 750 controls the database access control unit 76 so that the IP telephone terminal on the called side transmits a signal requesting degree information. In this case, the degree information returned from the called IP telephone terminal is used for selection by the selection unit 704 in step S184. When the degree information is not returned, the selection unit 704 can select the processing by regarding that the degree information having a predetermined content such as “reject” is returned. The IP telephone terminal on the called side returns the information stored in advance by itself. In some cases, the called IP telephone terminal may prompt the user to input the degree information each time the degree information is requested, and return the inputted degree information.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
