Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a communication system having a telephone device according to an embodiment of the present invention.

  This communication system includes an IP (Internet Protocol) network 1, a SIP (Session Initiation Protocol) server 2 connected to the IP network 1, and IP telephone devices 3 to 6. Actually, the SIP server 2 is provided for each communication carrier contracted by the subscriber of each IP telephone apparatus, but here, it is assumed to have one SIP server for convenience.

  The SIP server 2 uses SIP as a call control protocol, a function for associating a telephone number and an IP address between a caller IP telephone apparatus and a call partner IP telephone apparatus, and a call connection session It has a function of processing various SIP messages necessary for establishment. After a call connection session is established between these IP telephone apparatuses, voice packets are directly transmitted and received using RTP (Real-time Transport Protocol) or the like.

  FIG. 2 is a block diagram showing the configuration of each of the IP telephone devices 3 to 6 in FIG. As shown in FIG. 2, each IP telephone apparatus includes a control unit 11, a storage unit 12, a call processing unit 13, a voice processing unit 14, and a network interface unit 15.

  The control unit 11 is composed of a microcomputer or the like, and controls the entire IP telephone apparatus. The storage unit 12 stores the terminal identification information of this IP telephone device, its own identification information such as a telephone number, an IP address, and a user ID, and a telephone number such as a forwarding telephone number and an unwanted telephone number. Automatic response messages such as telephone response messages and absence response messages are stored.

  The call processing unit 13 processes various messages for call connection using SIP and packets of the various identification information. The call processing unit 13 includes various operation keys such as dial keys and function keys. The voice processing unit 14 includes a handset and a voice encoding / decoding processing circuit, and performs voice input / output and voice packet processing. The network interface unit 15 transmits and receives various packets between the IP network 1 and the call processing unit 13 and voice processing unit 14.

  Next, an example of a procedure from when a pair of IP telephone apparatuses in the communication system shown in FIG. 1 starts a call until it ends will be described with reference to FIG. In this figure, the IP telephone device 21 on the outgoing side and the IP telephone device 22 on the incoming side are any two of the IP telephone devices 3 to 6 in FIG. In the following description, the description of the operation of the internal block (FIG. 2) of the IP telephone apparatus is omitted unless particularly necessary.

  First, the IP telephone device 21 sends an “INVITE (call request)” message to the SIP server 2 in response to the user's call operation P1 (step S1). The SIP server 2 checks the received “INVITE (call request)” message, and sends a “100 TRYING (notification in progress)” message to notify the IP telephone apparatus 21 that the call request has been received (procedure). S2). In addition, the SIP server 2 sends an “INVITE (call request)” message to the IP telephone device 22 that is the call destination (step S3). At this time, even if the IP telephone device 22 is already in a call, the SIP server 2 transmits an “INVITE (call request)” message. That is, in the communication system shown in FIG. 1, a new call request can be notified to the IP telephone apparatus during the incoming call response of the IP telephone apparatus.

  The IP telephone device 22 that has received the “INVITE (call request)” message sends out a “100 TRYING (in-process notification)” message to notify the SIP server 2 that it has been received (step S4). Next, the IP telephone device 22 sends a “180 RINGING (calling notification)” message indicating that a call is being made (step S5) and outputs a ringing tone.

  Upon receiving the “180 RINGING (calling notification)” message, the SIP server 2 notifies the IP telephone device 21 of “180 RINGING (calling notification) to notify the IP telephone device 21 that the IP telephone device 22 is being called. ) "Message is sent (step S6). The IP telephone apparatus 22 stops outputting the ringing tone based on the response operation P2 of the user, and sends a “200 OK (incoming response)” message to the SIP server 2 to notify that the incoming call has been answered ( Procedure S7).

  The SIP server 2 that has received the “200 OK (incoming response)” message sends out a “200 OK (incoming response)” message to the IP telephone apparatus 21 (step S8). The IP telephone apparatus 21 that has received the “200 OK (incoming response)” message transmits an “ACK (acknowledgment response)” message to the SIP server 2 (step S9). The SIP server 2 sends an “ACK (acknowledgment response)” message to the IP telephone device 22 (step S10).

  As a result, a call can be made between the IP telephone device 21 and the IP telephone device 22 (step S11). This call is performed by exchanging voice packets directly between the IP telephone apparatus 21 and the IP telephone apparatus 22 without using the SIP server 2 using RTP.

  When the call is finished and the disconnection operation P3 is performed in the IP telephone apparatus 21, the IP telephone apparatus 21 transmits a “BYE (disconnection notification)” message to the SIP server 2 (step S12). The SIP server 2 that has received the “BYE (disconnection notification)” message transmits a “BYE (disconnection notification)” message to the IP telephone device 22 (step S13).

  The IP telephone device 22 that has received the “BYE (disconnection notification)” message transmits a “200 OK (acknowledgement)” message to the SIP server 2 (step S14). The SIP server 2 that has received the “200 OK (accepted)” message sends out a “200 OK (acknowledged)” message to the IP telephone apparatus 21 (step S15).

  Next, the operation when the nuisance call prevention function is set will be described. When the IP telephone apparatus of this embodiment receives a call that is not a nuisance call while sending an automatic response message to a nuisance call, the IP telephone apparatus ends the transmission of the automatic response message to the nuisance call and responds to a call that is not a nuisance call. Setting, (b) When another nuisance call is received while sending an automatic answer message to the nuisance call, the sending of the automatic answer message to the previous nuisance call is terminated and an automatic answer message is sent to the subsequent nuisance call (C) When a call that is not a nuisance call is received when an automatic answer message for a nuisance call is sent with the forwarding destination set, the sending of the automatic answer message for the nuisance call is terminated. , Setting to relay the call source and transfer destination, and (d) an automatic answer message for a nuisance call with the transfer destination set When a call that is not a nuisance call is received when a call is being made, there are four types of settings that are configured to continue sending an automatic response message to the nuisance call and to make a direct call between the call source and the transfer destination. Is possible.

  Hereinafter, each of these settings will be described in order. In the following description, the operation of the SIP server 2 is omitted for convenience. Therefore, for example, steps S1 and S2 in FIG. 3 will be described assuming that the originating IP telephone apparatus 21 has transmitted an “INVITE (call request)” message to the terminating IP telephone apparatus 22. Also, the exchange of the “100 TRYING (in-process notification)” message is omitted.

  FIG. 4 is a diagram showing an operation sequence in the case (a). In this figure, the destination IP telephone device 31 is one of the IP telephone devices 3 to 6 in the communication system shown in FIG. There are two other ordinary telephone callers 33.

  First, in response to the call operation P11 at the nuisance call origination source 32, the nuisance call origination source 32 transmits an “INVITE (call request)” message to the destination IP telephone apparatus 31 (step S21).

  The called IP telephone device 31 detects the telephone number (caller number) of the nuisance caller 32 included in the “INVITE (call request)” message (step ST1), and stores it in the storage unit 12. Based on the coincidence with the nuisance telephone number, it is determined as a nuisance call (step ST2). In addition, the receiving side IP telephone device 31 transmits a “180 RINGING (calling)” message to the nuisance call originator 32 (step S22).

  Next, the destination IP telephone apparatus 31 performs an automatic response (step ST3). As a result, the destination IP telephone apparatus 31 transmits a “200 OK (incoming response)” message to the nuisance call originator 32 (step S23), and then the nuisance call originator 32 sends an “ACK (acknowledgment response)” message. Transmit to the destination IP telephone device 31 (step S24). Then, the incoming side IP telephone device 31 transmits a nuisance response message to the nuisance call originator 32 (step S25).

  During transmission of the nuisance response message to the nuisance call originator 32 (during execution of step S25), the normal call originator 33 sends an “INVITE (call request)” message to the receiving side IP in response to the user's call operation P12. Transmit to the telephone device 31 (step S26).

  The destination IP telephone device 31 detects the telephone number (caller number) of the normal telephone caller 33 included in the “INVITE (call request)” message (step ST 4) and stores it in the storage unit 12. Based on the fact that it does not match the nuisance telephone number, it is determined that the telephone is not a nuisance call but a normal telephone (step ST5). Then, based on the determination result, the nuisance call response process is terminated (step ST6), and the incoming call process for the normal call originator 33 is started (step ST7).

  As a result, a “CANCEL” message is sent from the called IP phone device 31 to the nuisance call originator 32 (step S27), and then a “180 RINGING” message is sent from the called IP phone device 31. It is sent to the normal telephone source 33 (step S28). The subsequent operation procedure between the receiving side IP telephone apparatus 31 and the normal telephone source 33 is the same as that after S7 in FIG.

  FIG. 5 is a diagram showing an operation sequence in the case (b). In this figure, the transmission operation P11, procedures S21 to S25, and steps ST1 to ST3 are the same as those in FIG.

  During transmission of the nuisance response message to the nuisance call originator 32 (during execution of step S25), an "INVITE (call request)" message is sent in response to the user's call operation P13 at the nuisance call originator 34. 34 to the destination IP telephone device 31 (step S29).

  The called IP telephone device 31 detects the telephone number (caller number) of the nuisance caller 34 included in the “INVITE (call request)” message (step ST8), and stores it in the storage unit 12. It is determined that the call is a nuisance call based on the coincidence with the nuisance telephone number (step ST9). Then, based on the determination result, the destination of the automatic response message for the nuisance call is changed from the nuisance call originator 32 to the nuisance call originator 34 (step ST10).

  As a result, a “CANCEL” message is sent from the called IP phone device 31 to the nuisance call originator 32 (step S30), and then a “180 RINGING” message is sent from the called IP phone device 31. It is sent to the nuisance call originator 34 (procedure S31). The subsequent steps S32 to S34 are the same as the steps S23 to S25.

  FIG. 6 is a diagram showing an operation sequence in the case (c). Here, since the procedure before step S25 is the same as that in FIGS. 4 and 5, the illustration is omitted.

  During transmission of the nuisance response message to the nuisance call source 32 (during the execution of step S25), an “INVITE (call request)” message is sent in response to the user's call operation P14 at the normal call source 33. 33 is sent to the destination IP telephone apparatus 31 (step S35).

  The called IP telephone device 31 detects the telephone number (caller number) of the normal telephone caller 33 included in the “INVITE (call request)” message (step ST11), and stores it in the storage unit 12. Based on the fact that it does not match the nuisance telephone number, it is determined that the telephone is not a nuisance call but a normal telephone (step ST12). Then, based on the determination result, the nuisance call response process is terminated (step ST13), and the transfer process for the normal call originator 33 is performed (step ST14).

  As a result, a “CANCEL” message is sent from the destination IP telephone device 31 to the nuisance call originator 32 (step S 36), and then a “180 RINGING” message is sent from the destination IP phone device 31. It is sent to the normal telephone caller 33 (step S37). Next, an “INVITE (call request)” message is sent from the destination IP telephone apparatus 31 to the transfer destination 35 (step S38).

  Thereafter, transmission / reception of “180 RINGING” message (step S39), user response operation P15 at the transfer destination 35, transmission / reception of “200 OK (incoming response)” message (step S40), “ACK (acknowledgment response) ) "Message is transmitted and received (procedure S41), and then the telephone call source 33 and the transfer destination 35 are able to make a call via the destination IP telephone device 31 (procedure S42). During this call operation, the destination IP telephone device 31 relays voice packets transmitted and received between the normal telephone source 33 and the transfer destination 35.

  FIG. 7 is a diagram showing an operation sequence in the case (d). Here, since the procedure before step S25 is the same as that in FIGS. 4 and 5, the illustration is omitted.

  During transmission of the nuisance response message to the nuisance call source 32 (during execution of step S25), an “INVITE (call request)” message is transmitted from the normal call source 33 in response to the call operation P16 at the normal call source 33. And is received by the destination IP telephone apparatus 31 (step S43).

  The receiving side IP telephone apparatus 31 detects the telephone number (caller number) of the normal telephone caller 33 included in the “INVITE (call request)” message (step ST15), and stores it in the storage unit 12. Based on the fact that it does not match the nuisance telephone number, it is determined that the telephone is not a nuisance call but a normal telephone (step ST16). Then, based on the determination result, transfer to the normal telephone caller 33 is performed (step ST17). This transfer differs from the transfer in FIG. 6 in that the destination IP telephone device 31 is not connected so as to relay the voice packet of the call, but is directly connected between the normal telephone source 33 and the transfer destination 35. The connection is made so that packets are transmitted and received. For this reason, the receiving side IP telephone apparatus 31 can perform the transfer without forcibly terminating the transmission of the response message to the nuisance call source 32.

  In this transfer process, a “REFER (transfer)” message is transmitted from the destination IP telephone device 31 and received by the normal telephone source 33 (step S44). The normal telephone caller 33 detects the telephone number of the transfer destination 35 included in the “REFER (transfer)” message, and transmits an “INVITE (call request)” message thereto (step S45). The subsequent operation sequence between the normal telephone source 33 and the transfer destination 35 is the same as that after S4 in FIG.

  If the incoming IP telephone device 31 is configured so that a plurality of lines can be used simultaneously, the “CANCEL (forced termination)” message is not transmitted to the nuisance caller 32 in FIGS. 4 and 6. The “BYE (disconnection notification)” message may be transmitted after the transmission of the nuisance response message is completed.

  In the above embodiment, one IP telephone device can handle all four types (a) to (d), but one IP telephone device can handle one to three types. You may comprise as follows. In the above embodiment, the case where the nuisance call source 32, the normal call source 33, and the transfer destination 35 are all IP telephone devices has been described. However, one or more of them are connected to a public telephone line (PSTN). The present invention can also be applied to a communication system that is a fixed telephone device or a mobile phone device.
