More specifically, when “180 Ringing” is transmitted from the communication processing device 210 that has started the call to the communication processing device 220, a PRACK message is returned from the communication processing device 210 to the communication processing device 220. When the PRACK message is normally received, “200 OK” is returned as a success message from the communication processing device 220 to the communication processing device 210.

  Finally, if it is determined that the user is absent, the communication processing device 210 is disconnected halfway (step S430). Here, in the present embodiment, a new header is defined as an extension of SIP in the CANCEL message, which is a midway disconnection signal, importance information is added to the header, and the message is transmitted to the communication processing device 220. Specifically, a CANCEL message including a new header to which importance level information is added is sent from the communication processing device 210 to the communication processing device 220. When the CANCEL message is normally received, the communication processing device 220 succeeds in the communication processing device 210. “200 OK” is returned as the message. Then, when the midway disconnection process including the importance level information acquisition from the CANCEL message is completed, the communication processing device 220 transmits “487 Request Terminated” indicating that the call request has been terminated midway to the communication processing device 210. To do. In response to this, the communication processing device 210 notifies the communication processing device 220 of an ACK message indicating session establishment.

  In step S1001, the communication processing apparatus 210 waits for power ON. When the power is turned on, the communication processing device 210 initializes the device in step S1001.

  In step S1011, the communication processing device 210 determines whether or not there is a call instruction. If there is a call instruction, the communication processing device 210 executes call processing in step S1013. On the other hand, if it is not a call instruction, the communication processing device 210 determines in step S1021 whether or not an incoming call has been received. If there is an incoming call reception, the communication processing device 210 executes an incoming call process in step S1023. If neither the call instruction nor the incoming call reception is received, the communication processing device 210 determines whether or not there is an incoming call history display instruction in step S1031. If there is an incoming history display instruction, the communication processing device 210 executes an incoming history display call process in step S1033.

  In step S1005, the communication processing apparatus 210 determines whether the power is off. If the power is not OFF, the communication processing apparatus 210 returns to step S1011 and repeats the process.

(Call processing)
FIG. 11A is a flowchart showing a procedure of call processing (S1013) according to the present embodiment.

  In step S <b> 1111, the communication processing apparatus 210 determines whether or not the call is started. If it is a call start, the communication processing device 210 generates an INVITE message and transmits it to the call destination in step S1113. On the other hand, if the call is not started, the communication processing device 210 determines in step S1121 whether it is a midway disconnection instruction. If it is a halfway disconnect instruction, the communication processing device 210 displays the importance level designation screen of FIG. 3A in step S1123. Next, in step S1125, the communication processing apparatus 210 waits for the importance level selection designation by the user. If there is an importance instruction input by the user, the communication processing device 210 acquires the instructed importance in step S1127. In step S1129, the communication processing device 210 stores the importance information in the importance header of the CANCEL message. If there is no importance instruction input by the user, the Importance header is not described in the CANCEL message. In step S1131, the communication processing device 210 transmits a CANCEL message to the call destination.

  If it is not a call start instruction nor a midway disconnection instruction, the communication processing device 210 determines in step S1141 whether or not it is another instruction. If it is another instruction, the communication processing device 210 performs the other process instructed in step S1143. As shown in the sequence diagram of FIG. 5A, another message transmission or message reception is performed even during session establishment. These processes are included in the other processes in step S1143.

(Incoming call processing)
FIG. 11B is a flowchart showing a procedure of incoming call processing (S1023) according to the present embodiment.

  In step S1151, the communication processing apparatus 210 determines whether an INVITE message has been received. If it is INVITE reception, the communication processing apparatus 210 will acquire a call origin from a From header in step S1153. Next, in step S1155, the communication processing device 210 acquires the incoming call time from a timer (not shown). In step S1157, the communication processing apparatus 210 stores the caller in the incoming call history storage unit 605 using the incoming call time as a time stamp.

  On the other hand, if it is not INVITE reception, the communication processing apparatus 210 will determine whether it is reception of the CANCEL message in step S1161. If the CANCEL message is received, the communication processing apparatus 210 determines in step S1163 whether or not the CANCEL message includes an Importance header. If the “Importance” header is included, the communication processing device 210 acquires importance level information (level) from the “Importance” header in step S1165. On the other hand, if the CANCEL message does not include the Importance header, nothing is done. In step S1167, the communication processing apparatus 210 adds missed call information and importance information if there is importance information in the incoming call history storage unit 605. In FIG. 11A, when “not specified” is stored in the importance header when the importance is not specified, additional information to the importance header including “not specified” is acquired in step S1165 without step S1163. do it.

  If neither the INVITE reception nor the CANCEL reception is performed, the communication processing device 210 determines whether or not there is another instruction in step S1171. If it is another instruction, the communication processing device 210 performs the other process instructed in step S1173. As shown in the sequence diagram of FIG. 5A, another message transmission or message reception is performed even during session establishment. These processes are included in other processes in step S1173.

  In FIG. 11B, the calling source is acquired from the From header of the INVITE message. However, when the CANCEL message is received, the calling source may be acquired from the From header of the CANCEL message. In this case, the caller and importance information acquired from the CANCEL message may be stored as they are in the incoming call history without performing the process of associating the caller and importance information.

(Received call history display processing)
FIG. 11C is a flowchart showing a procedure of incoming call history display processing (S1033) according to the present embodiment.

  In step S1181, the communication processing device 210 determines whether the status of the incoming call history read from the incoming call history storage unit 605 is a missed call history. If it is a missed call history, the communication processing device 210 generates display data representing the missed call in step S1183. Next, in step S1185, the communication processing apparatus 210 determines whether importance level information is added. If the importance level information is added, the communication processing device 210 generates display data for displaying the importance level in step S1187. On the other hand, if importance information is not added, display data for displaying no designation is generated. In step S1191, the communication processing device 210 displays the incoming call history so that the missed calls and the importance can be identified.

  If it is not a missed call history, the communication processing device 210 determines in step S1193 whether it is another history. If it is another history, the communication processing device 210 generates display data for displaying another history in step S1195. In step S1191, the communication processing apparatus 210 displays an incoming call history that is not a missed call so as to be identifiable.

  According to the present embodiment, the importance level of a call can be determined from the importance level display of the missed call history of the called terminal. That is, since the importance level can be displayed in the missed call history of the receiving terminal, the call importance level can be grasped from the missed call history. Also, it is possible to explicitly notify the importance level of the corresponding call from the calling side to the called side.
