  According to the present invention, when an incoming call is received, the telephone control device can automatically determine the incoming call and display the corresponding lamp by simply transmitting an INVITE message to the IP telephone device. As a result, the IP telephone device can operate regardless of the telephone control device connected to the SIP control device having the SIP protocol, and can display the usage status of the IP line in an identifiable manner. Conventionally, a dedicated data transmission interface provided between the telephone control device and the IP telephone can be omitted.

The present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of a system to which an IP telephone apparatus of the present invention is applied. As shown in FIG. 1, this system includes a telephone control device 2 connected to an IP network 1 via an IP line and an IP telephone device 3 connected to the telephone control device 2. Here, the IP line is an apparent line (logical line) called a logical channel.

  As shown in FIG. 2, the IP telephone device 3 stores a control unit 31 that controls the entire IP telephone device 3 and a program 32 that is executed by the control unit 31. A storage unit 32 in which individual setting information 32B is stored, a communication I / F unit 33 that communicates with the telephone control device 2, a voice processing unit 34 that performs voice input / output processing such as voice packets, and an LCD The display unit 35 includes a display unit, an incoming call lamp, and the like, and an operation unit 36 including an incoming key and a dial key. The control unit 31 is provided with a message analysis unit 31 that analyzes a message transmitted from the telephone control device 2.

  FIG. 3 is a view showing the front appearance of the IP telephone device 3. In the IP telephone apparatus 3, as the operation unit 36, dial keys indicated by “1” to “9”, “0”, “*”, “#” and the like as shown in FIG. Etc. are provided. Also, in the IP telephone apparatus 3, as the display unit 35, a liquid crystal display indicated by reference numeral 35A, a lamp indicated by reference numeral 35B provided corresponding to the key 36A, an extension lamp indicated by reference numeral 35C, and the like Is provided.

  FIG. 4 is a diagram showing an example of the setting status of the individual setting information 32 </ b> B set in the storage unit 32 of the IP telephone device 3. In the IP telephone device 3, each key except for the dial key can be freely assigned to each key such as an incoming call key, a one-touch dial key, or a park hold key. Here, the keys LK1 to LK3 are keys assigned to identify the type of incoming call as described later. In the example of FIG. 4, the value “20” is set. This corresponds to the key 36A in FIG. Further, the lamp provided corresponding to this incoming call key is hereinafter referred to as an incoming call lamp (corresponding to the lamp 36B in FIG. 3). Further, in this IP telephone apparatus 3, other keys LK other than the keys LK1 to LK3 can be separately assigned as keys for selecting a line, and the value “20” is similarly set corresponding to these keys. The In the example of FIG. 4, the key LK4 is set to a value “10” indicating that it is a one-touch dial key, and the key LK5 is set to a value “30” indicating that it is a park hold key.

  In addition, in the individual setting information 32B set in the storage unit 32 of the IP telephone device 3, “Called Header Type =” described later is used as incoming call type determination information for determining the incoming call type on the IP telephone device 3 side. 1 "is set. Further, as the individual setting information 32B, a telephone number for identifying the type of incoming call such as “5100”, “5200”, “03XXXXYYYY”, etc., corresponding to each incoming key LK1, LK2, LK3 is a parameter. Is set as

  Here, when the telephone number “03XXXXYYYY” is received as the called number at the time of the incoming call, this incoming call is identified as an incoming call from the IP network 1 side, and in this case, it corresponds to the incoming call key corresponding to the telephone number. An incoming call lamp provided as an incoming call is displayed as described later. When the telephone number “5100” or “5200” is received as the called number at the time of the incoming call, the incoming call is identified as an incoming call from the other IP telephone apparatus accommodated in the telephone control apparatus 2. In this case as well, an incoming call lamp provided corresponding to the incoming call key corresponding to the telephone number is displayed as described later. Thus, depending on which incoming call lamp is displayed when an incoming call is received, the user can receive the incoming call from the IP network 1 side or an incoming call from another IP telephone apparatus accommodated in the telephone control apparatus 2. The type of incoming call can be identified.

  In this case, for example, the telephone number “5100” is set for individual incoming calls, and the telephone number “5200” is set for simultaneous incoming calls. The type can be identified. That is, when a telephone number “5100” is set for a certain IP telephone apparatus, and when the telephone number “5100” is received as a called number when an incoming call is received by the IP telephone apparatus, only that IP telephone apparatus has the telephone number. An incoming call lamp provided corresponding to the incoming call key corresponding to “5100” is displayed. Also, if all IP telephone devices accommodated in the telephone control device 2 set the telephone number “5200”, if the called number at the time of incoming call is “5200”, all IP telephone devices An incoming call lamp provided corresponding to the incoming call key corresponding to the number “5200” is displayed as an incoming call.

  By the way, when a call is made in a telephone (not shown) and the call number is transmitted to the IP network 1, if the call number is the telephone number of the IP telephone device accommodated in the telephone control device 2, An incoming call is notified from the IP network 1 to the telephone control device 2.

  The telephone control device 2 has a SIP (Session Initiation Protocol) protocol, and when an incoming call is notified from the IP network 1 side, an INVITE (session participation request) defined by the SIP protocol is sent to the IP telephone device 3. Send a message.

  This INVITE message includes incoming call type information A1, called number A2, and the like. Here, as the type information of the incoming call type information A1, each type including three types “1”, “2”, and “3” can be specified. Of these, the type “1” is the destination identification. It represents “P-Called-Party-ID” indicating information, and corresponds to “Called Header Type = 1” described above. The type “2” represents “Alert info” indicating the type information of the ringtone, and the type “3” represents “to” indicating the designation information of the destination.

  When receiving the INVITE message, the IP telephone device 2 identifies that an incoming call has arrived for itself. The received INVITE message is analyzed by the message analysis unit 31A in the control unit 31. In this case, the message analysis unit 31A determines whether or not the incoming call type determination information set as the individual setting information 32B in the storage unit 32 is in the received INVITE message, and the incoming call type determination information is included in the received INVITE message. If it is, it is further determined whether or not a parameter such as a telephone number set as the individual setting information 32B in the storage unit 32 is included in the received INVITE message. If the telephone number set as the individual setting information 32B exists in the received INVITE message as the called number A2, whether the incoming key is set as the individual setting information 32B corresponding to the telephone number. Judge whether or not.

  When the incoming key is set, the incoming lamp 35B corresponding to the incoming key is displayed, and in other cases, that is, the incoming type determination information set in the storage unit 32 is included in the received INVITE message. If there is no parameter such as the telephone number set in the storage unit 32 even if the incoming call type determination information is present in the received INVITE message, the telephone number, etc. If the incoming key corresponding to the telephone number is not set in the storage unit 32 even if the parameter exists in the received INVITE message, the extension lamp is displayed as an incoming call.

(First display operation at incoming call)
FIG. 5 is a flowchart showing the main operation of the present invention, and shows the first display operation at the time of an incoming call in the control unit 31 of the IP telephone apparatus 3. The operation of the main part of the present invention will be described in detail with reference to this flowchart.

  When a call is made from a telephone (not shown) and the call number is the telephone number of an IP telephone apparatus accommodated in the telephone control apparatus 2, an incoming call is notified from the IP network 1 to the telephone control apparatus 2 as described above. In this case, the telephone control device 2 transmits an INVITE message to the IP telephone device. When the control unit 31 of the IP telephone apparatus 3 receives this INVITE message via the communication I / F unit 33 (YES in step S1), the control unit 31 determines that the incoming call is received and causes the message analysis unit 31A to analyze the received INVITE message.

  In this case, the message analysis unit 31A determines whether or not the incoming call type determination information set as the individual setting information 32B in the storage unit 32 is included in the received INVITE message (step S3). If it is determined that the incoming call type determination information is included in the received INVITE message (YES in step S3), is there further a parameter such as a telephone number set as the individual setting information 32B in the storage unit 32? It is determined whether or not (step S4).

  If it is determined that the telephone number set in the storage unit 32 exists as the called number A2 in the received INVITE message (YES in step S4), the incoming key corresponding to the telephone number is stored in the storage unit. It is determined whether or not it is set as individual setting information 32B in 32 (step S5).

  When the message analysis unit 31A determines that the incoming key corresponding to the called number in the received INVITE message is set in the storage unit 32, the control unit 31 displays the incoming lamp 35B corresponding to the incoming key 36A. An incoming call is displayed (step S6). Note that when the message analysis unit 31A determines that the incoming call type determination information set in the storage unit 32 is not present in the received INVITE message (NO in step S3), the incoming call type determination information in the storage unit 32 is If it is determined that parameters such as the telephone number set in the storage unit 32 are not present in the received INVITE message even if they are present in the received INVITE message (NO in step S4), and are set in the storage unit 32 If it is determined that the incoming key corresponding to the telephone number is not set in the storage unit 32 even if the parameter such as the telephone number is present in the received INVITE message (NO in step S5), the control unit 31 Displays the extension lamp 35C as an incoming call (step S7). Such an incoming call operation is similarly performed in other IP telephone devices connected to the telephone control device 2.

  In this way, when the incoming call is received, the telephone control device 2 simply sends an INVITE message defined by the SIP protocol to the IP telephone device 3, and the IP telephone device 3 automatically determines and receives the corresponding lamp. Can be displayed. As a result, the IP telephone apparatus 3 can operate regardless of the telephone control apparatus 2 connected to the telephone control apparatus 2 having the SIP protocol, and can display the usage status such as incoming IP lines in an identifiable manner. As a result, a dedicated data transmission interface that is conventionally provided between the telephone control device and the IP telephone can be eliminated.

(Second display operation for incoming calls)
FIG. 6 is a flowchart showing the operation of the main part of the present invention, and shows the second display operation at the time of incoming call in the control unit 31 of the IP telephone apparatus 3. The operation of the main part of the present invention will be described in detail with reference to this flowchart.

  When a call is made from a telephone (not shown) and the call number is the telephone number of an IP telephone apparatus accommodated in the telephone control apparatus 2, an incoming call is notified from the IP network 1 to the telephone control apparatus 2 as described above. In this case, the telephone control device 2 transmits an INVITE message to the IP telephone device. When the control unit 31 of the IP telephone apparatus 3 receives this INVITE message via the communication I / F unit 33 (YES in step S11), the control unit 31 determines that the incoming call is received and causes the message analysis unit 31A to analyze the received INVITE message.

  The message analysis unit 31A determines the type of the incoming call classification information A1 included in the received INVITE message (step S12). Here, when it is determined that the type of the incoming call type information A1 matches the incoming call type determination information set as the individual setting information 32B in the storage unit 32 (YES in step S13), the incoming key identification is further performed. Processing is performed (step S14), and it is determined whether an incoming call key is set as the individual setting information 32B of the storage unit 32 (step S15).

  If the incoming key is set (YES in step S15), does the telephone number set as a parameter corresponding to the incoming key match the called number A2 included in the INVITE message? It is determined whether or not (step S16). If the two match (YES in step S16), the control unit 31 displays an incoming call lamp 35B corresponding to the incoming call key (step S17). Note that as the individual setting information 32B in the storage unit 32, when the incoming key is not set (in the case of NO in step S15), and even when the incoming key is set, it is set corresponding to the incoming key. If the telephone number does not match the incoming number A2 of the INVITE message (NO in step S16), the control unit 31 determines that the extension is incoming and displays the extension lamp 35C as an incoming call (step S18).

  If the type of incoming call type determination information set as the individual setting information 32B does not match the type of incoming call type information A1 included in the received INVITE message (NO in step S13), the control unit 31 Incoming call processing is performed (step S19). Such an incoming call operation is similarly performed in other IP telephone devices connected to the telephone control device 2.

(Display operation when answering an incoming call)
Next, the first display operation of the incoming call lamp when the IP telephone apparatus 3 responds to the incoming call will be described.
When the incoming call lamp 35B is displaying an incoming call, the corresponding incoming key 36A of the IP telephone apparatus 3 is pressed, and when this is detected by the control unit 31, the control unit 31 determines that it is a response to the incoming call and presses it. The incoming call response request including the telephone number (the aforementioned called number) corresponding to the received incoming key 36A is generated, and the 200 OK message including the incoming call response request is transmitted to the telephone control device 2 via the communication I / F unit 33. .

  When the incoming call response request is accepted by the telephone control device 2, the telephone control device 2 indicates to the IP telephone device 3 information indicating that the incoming incoming call lamp is self-use display (myline display). Information including (incoming lamp self-use display command information) and the called number transmitted from the IP telephone apparatus 3 in the incoming response request is included in the SIP protocol notify command (notification command) and transmitted. . On the other hand, for other IP telephone apparatuses connected to the telephone control apparatus 2, incoming information necessary for displaying the incoming lamps for the other party is displayed in the SIP protocol notify command. .

  Upon receiving the incoming lamp self-use display command information included in the notify command, the IP telephone device 3 that has made the incoming response request further receives the corresponding incoming call based on the called party number included in the notify command. The lamp 35B is determined, and the incoming call lamp 35B is switched from the incoming call display to the self-use display. Further, when the IP telephone device other than the IP telephone device 3 receives the incoming information included in the notify command, it determines its own incoming lamp 35B based on the information included in the notify command. The incoming call lamp 35B is switched from the incoming call display to the other person's use display, and a timer for a predetermined time is started. Then, after the timer expires, the other person's use display of the incoming lamp 35B is erased. It should be noted that the other IP telephone apparatus displays the incoming lamp 35B as a new incoming call while another incoming call is displayed on the incoming lamp 35B in another IP telephone apparatus other than the IP telephone apparatus 3 for a certain period of time. When a situation occurs, the control unit 31 of the other IP telephone apparatus switches the other person use display to the incoming call display.

  Thus, since the IP line is a logical line, the incoming lamp of the IP telephone apparatus 3 that has received the information of the INVITE message that matches the individual setting information 32B set in the storage unit 32 as described above when receiving an incoming call. It is configured to display only 35B as an incoming call, and when an IP telephone apparatus 3 receives an incoming call response, the IP telephone apparatus 3 that has made an incoming call response request receives the incoming number from the IP telephone apparatus 3 and the incoming lamp self-use The display command information is returned, and the IP telephone apparatus 3 is configured to automatically switch the corresponding incoming lamp from the incoming display to the self-use display.

  Further, in the present embodiment, the telephone control device 2 further displays the incoming call information necessary for the other party's use display of the incoming call lamp for other IP telephone devices other than the IP telephone device 3. The corresponding incoming lamps of these other IP telephone devices are displayed for use by others for a certain period of time so that they are included in the protocol notify command and sent to the other IP telephone device users. It is configured to identify that the user has responded to the incoming call.
