In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 shows an overview of the communication terminal 10 (B) of the present embodiment. Communication terminal 10 (B) shows an example of a preferred embodiment of a communication terminal. The communication terminal 10 (B) is provided in the communication system 1. The communication system 1 includes a communication terminal 10 (A), a communication control server 22, a packet switching network 40, and a circuit switching network 42 in addition to the communication terminal 10 (B).

  When receiving a voice call from the communication terminal 10 (A), the communication terminal 10 (B) receives in advance content used for notification of the incoming call. The communication terminal 10 (B) automatically reproduces the content when a call is received from the communication terminal 10 (A) and notifies the call from the communication terminal 10 (A). Examples of content include multimedia data including character data, still image or moving image data, or music data.

  The communication terminal 10 (B) performs appropriate control for the incoming call notification from the communication terminal 10 (A) or the voice call with the communication terminal 10 (A) according to the reception status of the content used for the incoming call notification. For the purpose of realizing, an integrated control unit 100 that integrates and controls data communication and voice call with the communication terminal 10 (A) is provided. The communication terminal 10 (A) has the same configuration as the communication terminal 10 (B). When the communication terminal 10 (A) and the communication terminal 10 (B) are not distinguished, they are simply labeled “communication terminal 10”. The same rules are used for other configurations described below.

  The communication terminal 10 (B) is connected to a packet switching network 40 such as the Internet and a circuit switching network 42 such as a mobile phone network. The communication terminal 10 (B) performs data communication with the communication terminal 10 (A) via the packet switching network 40. The communication terminal 10 (B) makes a voice call with the communication terminal 10 (A) via the circuit switching network 42. Voice calls include videophone calls.

  Data communication between the communication terminal 10 (B) and the communication terminal 10 (A) in the packet switching network 40 is controlled by the communication control server 22. For example, the communication control server 22 executes control for establishing a peer-to-peer session between the communication terminal 10 (B) and the communication terminal 10 (A). An example of the communication control server 22 is a SIP (Session Initiation Protocol) server.

  The called communication terminal 10 (B) receives the content from the communication terminal 10 (A). The communication terminal 10 (B) receives a call signal from the communication terminal 10 (A). When the communication terminal 10 (B) receives the call signal, the received content is automatically reproduced to notify the incoming call from the communication terminal 10 (A). By automatically reproducing the content, text is displayed on the display unit 128 (B) of the communication terminal 10 (B), and an image is displayed. The communication terminal 10 (B) reproduces sound.

  The calling communication terminal 10 (A) displays a multimedia call screen on the display unit 128 (A) of the communication terminal 10 (A). On the multimedia call screen, content to be transmitted to the called communication terminal 10 (B) is designated. The content can be specified by selecting a multimedia call content folder which is a multimedia call file from the storage unit 124 of the communication terminal 10 (A) or by inputting a folder name in the input field. Each content can be specified by selecting each data file of a still image, a moving image, sound, or text from the storage unit 124 of the communication terminal 10 (A) or inputting a file name in an input field. The text data can be specified not only by reading from a file recorded in the storage unit 124 but also by inputting an arbitrary character string in the input field.

  The still image or moving image, sound, and text data files that are contents to be transmitted are stored in the storage unit 124. The storage unit 124 may include a multimedia call content folder. The multimedia call content folder can store still images or a combination of moving image, sound, and text data files. By specifying the multimedia call content folder as a multimedia call file on the display unit 128 (A) of the communication terminal 10 (A), it is possible to specify contents to be transmitted in a batch.

  In specifying content, a camera may be activated to input a still image or a moving image as image data. The voice recorder may be activated to input voice as sound data. Text may be entered directly into the input field as text data.

  After designating the content to be transmitted, the communication terminal 10 (A) instructs the communication terminal 10 (B) to make a voice call. Upon receiving the call instruction, the communication terminal 10 (A) transmits content to the communication terminal 10 (B). Then, the communication terminal 10 (A) makes a voice call to the communication terminal 10 (B).

  Note that the communication system 1 may include a charging server 24. The accounting server 24 is connected to the packet switching network 40. The billing server 24 receives a notification that an event to be billed for the communication terminal 10 (B) or the communication terminal 10 (A) has occurred in the packet switching network 40 and records the billing for each communication terminal 10. For example, when an event that the content transmitted from the communication terminal 10 (A) uses for notification of an incoming call occurs in the communication terminal 10 (B), the billing server 24 receives the notification that the event has occurred and performs communication. Record the charge to terminal 10 (A).

  FIG. 2 shows a functional configuration example of the communication terminal 10 (B) of the present embodiment. The communication terminal 10 (B) includes an integrated control unit 100, a voice call unit 102, a voice call control unit 104, a data communication unit 110, and a data communication control unit 112. The communication terminal 10 (B) further includes a data file combining unit 114, a display size changing unit 116, a storage unit 124, a history holding unit 126, a display unit 128, an input / output unit 130, a timer unit 140, Is provided.

  The storage unit 124 includes a default data designation unit 152 and an automatic transmission setting storage unit 154. The input / output unit 130 includes a speaker 132, a key input unit 134, and a microphone 136. The timer unit 140 includes a first timer 141, a second timer 142, a third timer 143, a fourth timer 144, and a fifth timer 145.

  FIG. 3 shows a functional configuration example of the integrated control unit 100 included in the communication terminal 10 (B). The integrated control unit 100 includes a data communication information extraction unit 302, an incoming call rejection terminal match determination unit 304, an incoming call rejection message transmission unit 306, and a voice call information extraction unit 308. The integrated control unit 100 further includes a telecommunications carrier identification information acquisition unit 310, a collation unit 312, a content reproduction unit 314, an error analysis unit 316, and an error processing unit 318. The communication terminal 10 (A) has the same members as the communication terminal 10 (B).

  The communication terminal 10 (B) of the present embodiment links the packet communication and the voice call to notify the incoming call at the communication terminal 10 (B) using the content arbitrarily specified on the communication terminal (A) side. Is realized. The communication terminal 10 (B) has an integrated control unit 100 as an element for matching and integrating packet communication and voice call. Since the timer control by the fourth timer 144 and the fifth timer 145 described above spans both the control in the packet switching network 40 and the control in the circuit switching network 42, the integrated control unit 100 includes the fourth timer 144 and the fifth timer. 145 is integrated and controlled.

  A function of the communication terminal 10 (B) used when the communication terminal 10 (B) receives a voice call from the communication terminal 10 (A) will be described. The integrated control unit 100 controls the data communication control unit 112 and the voice call control unit 104 in an integrated manner.

  The voice call unit 102 performs a voice call with another communication terminal 10 through the circuit switching network 42. For example, the voice call unit 102 can receive a voice call from another communication terminal 10 through the circuit switching network 42. The voice call control unit 104 controls the voice call by the voice call unit 102. The voice call control unit 104 transmits a message notifying the incoming call after receiving the incoming call.

  The data communication unit 110 performs data communication with other communication terminals 10 through the packet switching network 40. For example, the data communication unit 110 can receive content from other communication terminals 10 through the packet switching network 40. For example, the data communication unit 110 can receive content as a data file obtained by combining a plurality of data selected from text data, moving image data, still image data, and sound data. For example, the data communication unit 110 can establish a peer-to-peer session between the communication terminal 10 (A) and the communication terminal 10 (B). Thereafter, the data communication unit 110 can receive content from the communication terminal 10 (B) via the peer-to-peer session.

  The data communication control unit 112 controls communication by the data communication unit 110. For example, when the data communication control unit 112 completes reception of content from the communication terminal 10 (A), the data communication control unit 112 can cause the data communication unit 110 to transmit a reception confirmation with the communication terminal 10 (A) as a transmission destination. For example, the data communication control unit 112 can include the type of receivable data in a response message to a request message for starting a session for transmitting content.

  The display size changing unit 116 changes the display size of the text, moving image, or still image to the display size of the display unit 128. The storage unit 124 temporarily stores the received content. The storage unit 124 stores incoming call rejection terminal identification information that is identification information of the communication terminal 10 that rejects incoming calls. Further, the storage unit 124 stores the content in association with the incoming call history. The display unit 128 displays text, moving images, or still images included in the content.

  The fourth timer 144 starts after transmitting a response message to a request message for starting a session for transmitting content, and stops after receiving the content. The fifth timer 145 starts after transmitting a confirmation message indicating that the content has been received, and stops after transmitting a message indicating notification of an incoming call or an end message for ending the session.

  The default data specifying unit 152 specifies default moving image data, still image data, or sound data. The data communication information extraction unit 302 extracts content transmission terminal identification information included in a request message for starting a session for communicating content. The incoming call rejection terminal match determination unit 304 determines whether the content transmission terminal identification information extracted by the data communication information extraction unit 302 matches the incoming call rejection terminal identification information stored in the storage unit 124.

  The incoming call rejection message transmission unit 306 transmits a rejection message in response to a request message for starting a session when the incoming call rejection terminal match determination unit 304 determines that they match. The voice call information extraction unit 308 extracts voice transmission terminal identification information included in the incoming call of the voice call.

  The content reproduction unit 314 reproduces data received from another communication terminal. For example, the content reproduction unit 314 can separate text data, moving image data, still image data, or sound data from the received data file and reproduce each separated data. For example, the content reproduction unit 314 can read the content from the storage unit 124 and reproduce the read content after the voice call control unit 104 transmits a message to notify the incoming call. For example, the content reproduction unit 314 can reproduce the content when the collation in the collation unit 312 matches.

  For example, the content reproduction unit 314 can read and reproduce the content stored in the storage unit 124 with reference to the incoming call history. For example, when the content includes moving image data with sound and sound data, the content reproduction unit 314 can preferentially reproduce the sound of the moving image data. For example, the content reproduction unit 314 can reproduce the content on the condition that the fourth timer 144 and the fifth timer 145 do not pass a predetermined time.

  For example, the content reproduction unit 314 can display text, a moving image, or a still image with the display size changed by the display size changing unit 116. If the default data designated by the default data designation unit 152 is set to be reproduced, the content reproduction unit 314 replaces the moving image data, still image data, or sound data included in the received content. , Play the default data. The collation unit 312 collates the content transmission terminal identification information with the voice transmission terminal identification information.

  A function of the communication terminal 10 (A) used when the communication terminal 10 (A) makes a voice call to the communication terminal 10 (B) will be described. The integrated control unit 100 integrates and controls the data communication control unit 112 and the voice call control unit 104 as in the case of an incoming call. For example, the integrated control unit 100 can read the display content corresponding to the type of error analyzed by the error analysis unit 316 from the storage unit 124 and display the read display content on the display unit 128.

  For example, when the error type is an error that the content transmission has failed and the automatic call setting storage unit 154 records information that the call is automatically executed, the integrated control unit 100 can automatically execute a voice call through the circuit switching network 42 without transmitting content. For example, the integrated control unit 100 can prohibit the process of transmitting content when the collation in the collation unit 312 does not match. For example, when any of the first timer 141, the second timer 142, or the third timer 143 has passed a predetermined time, the integrated control unit 100 can execute error processing by the error processing unit 318. Since the timer control by the first timer 141, the second timer 142, and the third timer 143 described above spans both the control in the packet switching network 40 and the control in the circuit switching network 42, the integrated control unit 100 includes the first timer 141, the second timer 142, and the third timer 143 are integrated and controlled.

  The voice call unit 102 performs a voice call with another communication terminal 10 through the circuit switching network 42. For example, the voice call unit 102 makes a voice call to another communication terminal 10 through the circuit switching network 42. The voice call control unit 104 controls the voice call by the voice call unit 102. For example, the voice call control unit 104 can cause the voice call unit 102 to transmit a call signal having the communication terminal 10 (B) as a call destination.

  In particular, the voice call control unit 104 can cause the voice call unit 102 to transmit a call signal to the other communication terminal 10 as a call destination after the data communication unit 110 completes the transmission of the content. The completion of the content transmission can be detected by the data communication unit 110 receiving the reception confirmation. That is, after the data communication unit 110 receives the reception confirmation, the voice call control unit 104 can cause the voice call unit 102 to transmit a call signal with the communication terminal 10 (B) as the called party.

  The data communication unit 110 performs data communication with other communication terminals 10 through the packet switching network 40. For example, the data communication unit 110 can transmit content to another communication terminal 10 through the packet switching network 40. For example, the data communication unit 110 can establish a peer-to-peer session between the communication terminal 10 (A) and the communication terminal 10 (B). Thereafter, the data communication unit 110 can transmit data to the communication terminal 10 (B) via the peer-to-peer session. Further, the data communication unit 110 can transmit one data file combined by the data file combining unit 114 as content.

  The data communication control unit 112 controls communication by the data communication unit 110. For example, the data communication control unit 112 can cause the data communication unit 110 to transmit the content in response to a call instruction to another communication terminal 10 that has designated the content. Further, the data communication control unit 112 can receive a response message for a request message for starting a session for communicating content, and extract the types of receivable data included in the response message.

  The data file combining unit 114 combines a plurality of data to be transmitted as contents. For example, the data file combining unit 114 can combine a plurality of data selected from text data, moving image data, still image data, and sound data into one data file. For example, the data file combining unit 114 can combine a plurality of data as long as the receivable data types extracted by the data communication control unit 112 are limited.

  The storage unit 124 stores display contents corresponding to the type of error. The storage unit 124 stores default communication carrier identification information that is identification information of a predetermined communication carrier. The display unit 128 displays the details of the error.

  The first timer 141 starts after transmitting a request message for starting a session for communicating content, and stops after receiving a response message to the request message. The second timer 142 starts after transmitting a confirmation message for the response message, and stops after receiving a confirmation message for content transmission. The third timer 143 is started immediately before or after the call is made, and stops after receiving the end message transmitted by the other communication terminal 10 that has received the call to end the session.

  The automatic transmission setting storage unit 154 records information on whether or not to automatically execute a call without transmitting the content when the content transmission fails. The error analysis unit 316 analyzes the communication error notification from the data communication control unit 112. The error processing unit 318 causes the voice call unit 102 to control the calling of the voice call according to the type of error.

  The communication carrier identification information acquisition unit 310 acquires communication carrier identification information for identifying a communication carrier. The collation unit 312 collates the default communication carrier identification information stored in the storage unit 124 with the communication carrier identification information acquired by the communication carrier identification information acquisition unit 310.

  The storage unit 124 includes a folder for each content type, for example, a moving image folder, a still image folder, a music folder, and a text folder, and may store content according to the type of each folder. The storage unit 124 may include a multimedia call content folder and store various multimedia contents. By designating the multimedia call content folder, various multimedia contents stored therein can be collectively designated.

  The display unit 128 may be a liquid crystal display device, for example. The input / output unit 130 includes a speaker 132, a key input unit 134, and a microphone 136. The speaker 132 may be an audio output device of the communication terminal 10 and outputs, for example, audio in content reproduction output.

  The key input unit 134 may be one of input devices of the communication terminal 10 and inputs, for example, in an input field for specifying content. Alternatively, the text is input in the input field when the text is input as the content. Furthermore, the key input unit 134 inputs a call instruction designating the content.

  The microphone 136 collects sound. For example, the input can be voice recorder input as content. Each of the first timer 141, the second timer 142, the third timer 143, the fourth timer 144, and the fifth timer 145 may be a physically independent timer, or physically one timer. May be made to function as respective timers by software.

  FIG. 4 shows an example of a processing flow in the communication system 1. In this example, a processing flow when the communication terminal 10 (B) receives a voice call from the communication terminal 10 (A) is illustrated. Similarly, the following description using the drawings illustrates a case where the communication terminal 10 (B) receives a voice call from the communication terminal 10 (A).

  When the communication terminal 10 (A) specifies the content to be transmitted and receives a call instruction to the communication terminal 10 (B), the communication terminal 10 (A) transmits a “SIP INVITE” message to the communication control server 22 (A) (S401). ). The communication terminal 10 (A) communicates with the communication control server 22 (A) or the circuit switch (A) via the gateway. Similarly, the communication terminal 10 (B) communicates with the communication control server 22 (B) or the circuit switch (B) via the gateway. The gateway may be a node that supports a mobile phone network, for example, and may be a device for interworking with a network outside the mobile phone network such as the Internet. In the following description, description of the gateway is omitted.

  The communication control server 22 (A) transmits the received “SIP INVITE” message to the communication control server 22 (B) (S 402). The communication control server 22 (B) transmits the received “SIP INVITE” message to the communication terminal 10 (B) (S 403). The communication terminal 10 (B) that has received the “SIP INVITE” message transmits a “200 OK (INVITE)” message to the communication control server 22 (B) (S 404). In the figure, “200 OK (INVITE)” may be displayed as “200 OK (INV)”.

  The communication control server 22 (B) transmits the received “200 OK (INVITE)” message to the communication control server 22 (A) (S 405). The communication control server 22 (A) transmits the received “200 OK (INVITE)” message to the communication terminal 10 (A) (S406).

  The communication terminal 10 (A) that has received the “200 OK (INVITE)” message transmits a “SIP ACK” message to the communication control server 22 (A) (S 407). The communication control server 22 (A) transmits the received “SIP ACK” message to the communication control server 22 (B) (S408). The communication control server 22 (B) transmits the received “SIP ACK” message to the communication terminal 10 (B) (S409). In this way, a peer-to-peer session by SIP is established between the communication terminal 10 (A) and the communication terminal 10 (B).

  In the peer-to-peer session, there is no fixed client or server, and each of the communication terminals 10 on the packet switching network 40 functions as both a client and a server. Therefore, it is advantageous for stream transmission of multimedia data having a large capacity such as image data by reducing the load on the server or the like existing on the packet switching network 40.

  When the peer-to-peer session is established in step S409, the communication terminal 10 (A) and the communication terminal 10 (B) execute a TCP 3-way handshake to establish a connection in the TCP layer (S410). The communication terminal 10 (A) transmits the specified content data using the “MSRP SEND” message to the established TCP connection (S411).

  When the reception of the content data by the communication terminal 10 (B) is completed, the communication terminal 10 (B) transmits a “200 OK (SEND)” message (S412). In this way, the content data is transmitted from the communication terminal 10 (A) to the communication terminal 10 (B). The communication terminal 10 (B) temporarily stores the received content data in the storage unit 124.

  Upon receiving the “200 OK (SEND)” message, the communication terminal 10 (A) transmits a “SETUP” message defined in the 3GPP (Third Generation Partnership Project) specification number “24.008” to the circuit switch (A). Then, a call is made (S413). The circuit switch (A) that has received the “SETUP” message transmits an “IAM” message to the circuit switch (B) (S414). The circuit switch (B) that has received the “IAM” message transmits a “SETUP” message to the communication terminal 10 (B) (S415). The “SETUP” message is an example of a call signal for a voice call transmitted from the communication terminal 10 (A) to the communication terminal 10 (B).

  Receiving the “SETUP” message, the communication terminal 10 (B) transmits an “ALERTING” message defined in the 3GPP specification number “24.008” to the circuit switch (B) (S 416). The circuit switch (B) that has received the “ALERTING” message transmits an “ACM / CPG” message to the circuit switch (A) (S417).

  The circuit switch (A) that has received the “ACM / CPG” message transmits an “ALERTING” message to the communication terminal 10 (A) (S418). The communication terminal 10 (A) knows from the received “ALERTING” that the communication terminal 10 (B) is in the incoming call notification state, that is, the content is being reproduced.

  In step S418, the communication terminal 10 (B) transmits an “ALERTING” message to the circuit switch (B), and then transmits a “SIP BYE (success)” message to the communication control server 22 (B) (S419). The communication control server 22 (B) transmits the received “SIP BYE (success)” message to the communication control server 22 (A) (S 420). The communication control server 22 (A) transmits the received “SIP BYE (success)” message to the communication terminal 10 (A) (S421).

  When the user responds at the communication terminal 10 (B), the communication terminal 10 (B) transmits a “CONNECT” message defined in the 3GPP specification number “24.008” to the circuit switch (B) (S422). The circuit switch (B) that has received the “CONNECT” message transmits an “ANM” message to the circuit switch (A) (S423). The circuit switch (A) that has received the “ANM” message transmits a “CONNECT” message to the communication terminal 10 (A) (S424).

  When the communication terminal 10 (A) receives the “CONNECT” message, the voice call (CS Call) is opened (S425). When the communication terminal 10 (A) receives a “SIP BYE (success)” message in step S421, the communication terminal 10 (A) transmits a “200 OK (BYE)” message to the communication control server 22 (A). (S426). The communication control server 22 (A) transmits the received “200 OK (BYE)” message to the communication control server 22 (B) (S427). The communication control server 22 (B) transmits the received “200 OK (BYE)” message to the communication terminal 10 (B) (S428). In this way, the SIP peer-to-peer session between the communication terminal 10 (A) and the communication terminal 10 (B) is terminated.

  In the designation of content in the communication terminal 10 (A), an image file, a sound file, and a text file of still images or moving images can be designated individually. These files can be specified in combination. For example, text and still image, text and moving image, text and sound, still image and sound, still image and moving image, text, still image and sound can be combined. An example of the maximum file size is 100 kB.

  The image file, the sound file, or the text file may be stored in the multimedia call content folder alone or in combination, and the multimedia call content folder may be specified to specify them collectively. A plurality of multimedia call content folders can be provided, and appropriate names can be used according to scenes. For example, it is possible to generate and use different multimedia call content folders for “for children”, “for her”, “for family”, and “for friends”.

  In addition, for content, image data shot on the spot by a camera or the like can be designated as an image file, and sound data recorded on the spot by a voice recorder can be designated as a sound file. A text file can be specified by entering text data in the text input field on the spot. Dedicated content may be downloaded from a website and specified.

  Examples of contents that can be specified include the following file formats. As text data, for example, data in a text file format (txt format) can be exemplified. Examples of still image data include data in jpg format (jpeg format, jpe format), png format, gif format, and animated GIF format.

  Examples of moving image data include data in 3gp format, mp4 format, swf format, and mmf format. Examples of the audio data include amr format, mid format (midi format), 3gp format, mp4 format, and SP-MIDI format data. These types of files can be specified in appropriate combinations, but the combinations may not be appropriate. The moving image data may be Flash (trademark).

  Calling a voice call includes a videophone call. An existing calling method can be applied as a calling method. For example, a calling method such as number input, outgoing from the hot status list, outgoing from the address book, outgoing from the incoming call history, outgoing from the outgoing call history, etc. can be applied.

  Further, if there is a call history accompanying content transmission in the telephone number of the call destination, the call operation may be executed with the content used for the call as a default. Of course, it is possible to cancel a call with content transmission and switch to a call without content transmission. Note that after performing an operation to instruct a call, a progress bar may be displayed during transmission of the content to notify the user of the progress.

  When a text file, a still image file, a moving image file, a sound file, or a combination thereof is designated as the content, the mode of incoming call notification is determined according to each designated (received) data. For example, when a text file is designated as the content, the received text is displayed on the display unit 128, and the default ringtone of the communication terminal 10 (B) is used as the ringing sound. When a still image file is designated, the received still image is displayed on the display unit 128, and a default ringtone is used as a ringing sound.

  When a moving image file is designated, the received moving image is reproduced on the display unit 128, and a sound included in the moving image is used as a ringing sound. When the sound data is designated, a display screen depending on the communication terminal 10 (B) is displayed on the display unit 128, and the received sound is reproduced as a ringing sound. When a text file and a still image file are designated, the received text and still image are displayed on the display unit 128, and a default ringtone is used as a ringing sound. When a text file and a moving image file are designated, the received text and moving image are displayed on the display unit 128, and a sound included in the moving image is used as a ringing sound.

  When a text file and a sound file are designated, the received text is displayed on the display unit 128, and the received sound is reproduced as a ringing sound. When a still image file and a sound file are designated, the received still image is displayed on the display unit 128, and the received sound is reproduced as a ringing sound. When a still image file and a moving image file are designated, the received still image is displayed on the display unit 128, and a sound included in the moving image is used as a ringing sound. The received moving image may be displayed on the display unit 128, and a sound included in the moving image may be used as a ringing sound. When a text file, a still image file, and a sound file are designated, the received text and still image are displayed on the display unit 128, and the received sound is played as a ringing sound.

  The content received in step S411 may be used for notification of an incoming call, and then stored and reproduced as appropriate. The stored content can be edited. The stored content can be reused later as content for incoming call notification.

  When the content is not normally transmitted in step S411, an incoming call notification without the content transmission can be made. For example, an incoming call can be notified by playing a ring tone set in advance in the communication terminal 10 (B).

  Even if the content is normally transmitted in step S411 and the communication terminal 10 (B) normally receives the content, the communication terminal 10 (B) may not receive the “SETUP” message in step S415. . If the communication terminal 10 (B) does not receive the “SETUP” message, the incoming call is not notified, and the incoming call history does not remain in the incoming call history. In such a case, the communication terminal 10 (B) should not discard the received content and recognize it as a charging event related to content transmission. Examples of the case where the communication terminal 10 (B) does not receive the “SETUP” message include the following cases.

  For example, there is a case where an answering machine service or a transfer telephone service is set and the call is transferred without calling. Or, there may be a case where an incoming call is made as an interruption call and an interruption voice call is not set. Alternatively, there are cases where incoming call restrictions or number blocks are set. In such a case, even if the content is received by the communication terminal 10 (B), the content is not used for notification of an incoming call in the communication terminal 10 (B).

  In addition, when the incoming call rejection setting is performed in the communication terminal 10 (B), the content may be received and the incoming call history may remain. However, since the incoming call rejection setting is made, the incoming call is not notified, so the content is discarded and no charge is made. On the other hand, for example, when an interruption call during a voice call is received and an interruption voice call is set, or when an incoming call is received during a PoC session, the content is received and charged. Recognized as an event. In this case, the incoming call is notified by the reproduction of the content, but it is controlled not to reproduce the sound.

  Further, the communication terminal 10 (B) may not receive the “SETUP” message due to, for example, a line failure. In this case, the determination that the “SETUP” message is not received can be made, for example, by the timer unit 140 provided in the communication terminal 10 (B).

  If these contents are not normally received, or if an incoming call signal is not received after the contents are received, a “SIP BYE (success)” message is not transmitted in step S419, for example, “SIP BYE (failure)”. Message is sent. If the communication terminal 10 (B) cancels the content reception, a “SIP BYE (cancel)” message is transmitted in step S419. In such a case, the communication control server 22 (A) and the communication control server 22 (B) receive a “SIP BYE (failure)” or “SIP BYE (cancel)” message, and the billing server 24 charges. Not.

  In step S409, after the communication control server 22 (B) transmits a “SIP ACK” message to the communication terminal 10 (B), the communication control server 22 (B) receives “SIP BYE” from the communication terminal 10 (B). Message may not be received. In this case, the communication control server 22 (B) generates a “SIP BYE (failure)” message and transmits it to the communication control server 22 (A). The determination that the communication control server 22 (B) does not receive the “SIP BYE” message is made when, for example, an appropriate timer is started in the communication control server 22 (B) and the message cannot be received by the lapse of a predetermined time. It can be determined that the “SIP BYE” message is not received. Also in this case, the billing server 24 is not charged.

  The information “success”, “failure” or “cancel” is described in the header of the “SIP BYE” message. The communication control server 22 transmits the accounting information including the header to the accounting server 24. The billing server 24 can check the header to determine whether the incoming call is successful, failed, or canceled.

  The communication terminal 10 (A) does not transmit content to other communication terminals 10 outside the communication range of a predetermined communication carrier. Specifically, the communication terminal 10 (A) determines a communication carrier that can be used at the current position before the process (step S401) of transmitting a “SIP INVITE” message to the communication control server 22 (A). Acquire identification information of the carrier. Then, the communication terminal 10 (A) collates the default communication carrier identification information stored in the storage unit 124 with the acquired communication carrier identification information. The communication terminal 10 (A) prohibits the process of transmitting content when the default communication carrier identification information and the communication carrier identification information do not match.

  When the process of transmitting the content is prohibited, the communication terminal 10 (A) automatically executes a voice call through the circuit switching network without transmitting the content. In other words, without performing the process of transmitting the “SIP INVITE” message to the communication control server 22 (step S401), the “SETUP” message is transmitted to the circuit switch (A) (step S413). Each process for performing a voice call with the communication terminal 10 (B) is performed.

  Communication terminal 10 (A) can communicate with communication terminal 10 (B) by roaming even overseas. Here, the packet communication fee when roaming is used may be higher than the packet communication fee when roaming is not used. The communication terminal 10 (A) transmits the content to the communication terminal 10 (B) unless the overseas communication carrier is defined in the default communication carrier identification information stored in the storage unit 124, that is, Then, a process for performing a voice call with the communication terminal 10 (B) is started without performing packet communication. In this case, no packet communication fee is charged for the communication terminal 10 (A). Therefore, the communication fee that the user of the communication terminal 10 (A) should pay can be reduced.

  Further, the communication terminal 10 (B) includes the type of receivable data in the “200 OK (INVITE)” message transmitted to the communication terminal 10 (A). The communication terminal 10 (A) specifies the type of data that can be received by the communication terminal 10 (B) from the received “200 OK (INVITE)” message. The communication terminal 10 (A) includes only data that can be received by the communication terminal 10 (B) in the content and transmits the data to the communication terminal 10 (B). As a result, there is a case where the addition on the content transmission path can be reduced.

  A method for reproducing content by the communication terminal 10 (B) will be described. The communication terminal 10 (B) automatically reproduces the content held in the storage unit 124 at the timing of transmitting the “ALEARTING” message to the communication terminal (A) (T3 timing shown in FIG. 4). Specifically, the communication terminal 10 (B) reads the content stored in the storage unit 124 and reproduces the read content. Thereby, the communication terminal 10 (B) notifies the user of the communication terminal 10 of an incoming call. Note that the communication terminal 10 (B) reproduces the content on the condition that the fourth timer 144 and the fifth timer 145 do not pass a predetermined time.

  The communication terminal 10 (B) reproduces the content on the condition that the communication terminal 10 that has transmitted the “SETUP” message matches the communication terminal 10 that has transmitted the “SIP INVITE” message. Specifically, the communication terminal 10 (B) extracts voice transmitting terminal identification information included in the “SETUP” message at the timing of receiving the “SETUP” message (timing T2 shown in FIG. 4). For example, the communication terminal 10 (B) extracts the telephone number of the communication terminal 10 (A) included in the “SETUP” message.

  Then, the communication terminal 10 (B) extracts the content transmission terminal identification information included in the “SIP INVITE” message. For example, the data communication information extraction unit 302 extracts P-ASSERTED-IDENTITY included in the “SETUP” message. The communication terminal 10 (B) collates the extracted content transmission terminal identification information with the voice transmission terminal identification information, so that the communication terminal 10 that is the transmission source of the “SETUP” message and the transmission source of the “SIP INVITE” message are It is determined whether or not the communication terminal 10 matches.

  If the communication terminal 10 (B) determines that they match, the content is reproduced at the timing (the timing of T3 shown in FIG. 4) at which the “ALEARTING” message is transmitted to the communication terminal (A). If the communication terminal 10 (B) determines that they do not match, the communication terminal 10 (B) does not reproduce the content. In this case, the communication terminal 10 (B) reproduces a predetermined telephone ring tone. According to the communication terminal 10 of the present embodiment, it is possible to prevent the content transmitted from another communication terminal from being reproduced in conjunction with the incoming voice call from the communication terminal 10 that is not the content transmission source. Can do.

  Further, the communication terminal 10 (B) can preferentially reproduce either the content transmitted from the communication terminal (A) or any content already stored in the communication terminal (B). . For example, the communication terminal 10 (B) stores data in which a file name for identifying moving image data, still image data, or sound data designated in advance is written.

  The communication terminal 10 (B) determines the presence or absence of the designated data by referring to the data. If the communication terminal 10 (B) determines that there is designated data, it identifies the designated data from the data. Then, the communication terminal 10 (B) reproduces the specified data. When the communication terminal 10 (B) determines that there is no designated data, the communication terminal 10 (B) plays the content transmitted from the communication terminal (A) with priority.

  FIG. 5 shows an example of a content designation method by the communication terminal 10 (A). A display screen 500 is displayed on the display unit 128 of the communication terminal 10 (A). Communication terminal 10 (A) accepts designation of content by the user via display screen 500. Display screen 500 includes a “text” field, an “image” field, and a “sound” field.

  Text data is entered in the “text” field. Text data is directly input in the “text” field. The user may be allowed to input text data from a text editing screen linked to the “text” field.

  In the “image” field, a file name of image data (moving image data or still image data) is input. In the “image” column, the file name of the image data is directly input. The user may select the file name of the image data from the file list linked to the “image” column. Alternatively, a camera provided in the communication terminal 10 (A) may be activated to cause the user to capture image data, and a file name of the captured image data may be automatically input.

  In the “Sound” field, the file name of the sound data is entered. In the “Sound” column, the file name of the sound data is directly input. The user may select the file name of the sound data from the file list linked to the “sound” column. Alternatively, a voice recorder provided in the communication terminal 10 (A) may be activated to cause the user to record sound data, and a file name of the recorded sound data may be automatically input.

  The communication terminal 10 (A) creates a multimedia file in which text data, image data, and sound data specified by each input field are combined into one data file. Communication terminal 10 (A) transmits the created multimedia file to communication terminal 10 (B).

  Here, “74/100 KB” included in the display screen 500 indicates the total size of each piece of data designated by the input field and the maximum size of the content that is preset. The user can specify a plurality of files to be combined within a range not exceeding 100 KB which is the maximum content size. Note that the maximum content size may or may not be changeable by the user.

  By combining a plurality of data into one data file, the communication terminal 10 may be able to manage content easily. Also, it may be possible to reduce the time required for content transmission / reception rather than individually transmitting / receiving a plurality of data. By predetermining the maximum content size, it may be possible to reduce the load on the content transmission path.

  Display screen 500 includes a “menu” button and a “preview” button. When the “menu” button is selected, the communication terminal 10 (A) displays a “save” menu and a “call” menu on the display unit 128.

  When the “Save” menu is selected, the communication terminal 10 (A) saves the multimedia file. The communication terminal 10 (A) may store the multimedia file in a predetermined storage location or may store it in a storage location designated by the user.

  When the “call” menu is selected, the communication terminal 10 (A) accepts input of the telephone number of the communication terminal 10 that is the transmission destination of the multimedia file. Then, the communication terminal 10 (A) starts a multimedia file transmission process.

  When the “Preview” button is selected, the communication terminal 10 (A) reproduces each data included in the other communication terminals 10. As a result, the communication terminal 10 (A) tells the user of the communication terminal 10 (A) how each data included in the multimedia file is reproduced on the destination communication terminal 10. It can be confirmed.

  Communication terminal 10 (A) receives a response message (“200 OK (INV)” message) to a request message (“SIP INVITE” message) for starting a session for communicating content, and is included in the response message There are cases where the type of data that can or cannot be received is extracted. In this case, the communication terminal 10 (A) is limited only to the type of receivable data extracted by the data communication control unit 112, or to data other than the type of unreceivable data extracted by the data communication control unit 112. Combine multiple data.

  For example, when the response message includes text data and sound data as receivable data types, that is, when image data is not included, the data file combining unit 114 sets the text data and sound data. Are to be combined. When the user of the communication terminal 10 (A) operates the communication terminal 10 (A) for combining image data, the error indicating that the communication terminal 10 (A) cannot combine image data The message may be displayed on the display unit 128. Further, the communication terminal 10 (A) may lock an operation for combining image data. The communication terminal 10 (A) may not transmit image data to the communication terminal 10 that cannot receive image data after combining the image data.

  FIG. 6 shows an example of a multimedia file. A file 600 indicates a multimedia file generated by the data file combining unit 114 of the communication terminal 10 (A). The file 600 includes data 601 including text data, data 602 including sound data, and data 603 including image data. Further, each of the data 601 to 603 is shown in a predetermined format. Each of the data 601-603 includes identification information for identifying the type of data.

  The file 600 is transmitted from the communication terminal 10 (A) to the communication terminal 10 (B). The communication terminal 10 (B) that has received the file 600 separates text data, image data, or sound data from the received file 600 based on the format information distributed in advance by e-mail or the like. And the communication terminal 10 (B) identifies the kind of data about each of the data 601-603 by the identification information of each separated data. Then, the communication terminal 10 (B) reproduces the identified data by a reproduction method corresponding to the identified type of each data.

  When the file 600 includes moving image data with sound and sound data, the communication terminal 10 (B) plays the sound of the moving image data with priority. Thereby, the communication terminal 10 (B) can display a moving image and output a natural sound that matches the displayed moving image.

  When the communication terminal 10 (B) stores the received file 600, the communication terminal 10 (B) divides the plurality of data included in the file 600 for each data. The communication terminal 10 identifies the type of the data by the identification information included in the data for each divided data. The communication terminal 10 stores the identified data in a storage location corresponding to the type of the data.

  FIG. 7 shows an example of error processing by the communication terminal 10 (A). Here, a case where the communication terminal 10 (B) does not support this service will be described. The case where the communication terminal 10 (B) does not support this service means that the communication terminal 10 (B) does not have a function of receiving content from the communication terminal 10 (A). It may be a case where the content received from the communication terminal 10 (A) is not reproduced and the function of notifying the incoming call is not provided.

  When the communication terminal 10 (A) specifies the content to be transmitted and receives a call instruction to the communication terminal 10 (B), the communication terminal 10 (A) transmits a “SIP INVITE” message to the communication control server 22 (A). The communication control server 22 (A) transmits the received “SIP INVITE” message to the communication control server 22 (B).

  The communication control server 22 (B) that has detected that the communication terminal 10 (B) does not support this service transmits an “Error Code XXX” message indicating that to the communication control server 22 (A). The communication control server 22 (A) transmits the received “Error Code XXX” message to the communication terminal 10 (A).

  The communication terminal 10 (A) analyzes the received “Error Code XXX” message. Then, the communication terminal 10 (A) reads the display content 710 corresponding to the analyzed error type from the storage unit 124, and displays the read display content 710 on the display unit 128.

  Thereby, the communication terminal 10 (A) notifies the user of the communication terminal 10 (A) that the communication terminal 10 (B) does not support this service. The display content 710 includes options for selecting subsequent processing according to the type of error. The communication terminal 10 (A) can make the user of the communication terminal 10 (A) easily select the subsequent process according to the type of error.

  Display content 710 includes an option of whether or not to stop the transmission of the content and switch to a voice call. When the user of the communication terminal 10 (A) has selected to switch to calling a voice call, the communication terminal 10 (A) transmits a “SETUP” message to the circuit switch (A), followed by Then, each process for making a voice call is performed. Note that any one of the communication terminal 10 (B), the communication control server 22 (A), and the communication terminal 10 (A) may detect an error and issue “Error Code XXX”.

  FIG. 8 shows an example of error processing by the communication terminal 10 (A). Here, a case will be described in which communication terminal 10 (B) is in a state where content cannot be received. The state in which the communication terminal 10 (B) cannot receive content means that the communication terminal 10 (B) is turned off when the communication terminal 10 (B) is communicating with another communication terminal 10. The state may be a case where the transmission path between the communication terminal 10 (B) and the communication control server 22 (B) is disconnected.

  When receiving the designation of the content to be transmitted and receiving a call instruction to the communication terminal 10 (B), the communication terminal 10 (A) transmits a “SIP INVITE” message to the communication control server 22 (A). The communication control server 22 (A) transmits the received “SIP INVITE” message to the communication control server 22 (B). The communication control server 22 (B) transmits the received “SIP INVITE” message to the communication terminal 10 (B).

  The communication terminal 10 (B) that determines that the content cannot be received transmits an “Error Code YYY” message indicating that to the communication control server 22 (B). The communication control server 22 (B) transmits the received “Error Code YYY” message to the communication control server 22 (A). The communication control server 22 (A) transmits the received “Error Code YYY” message to the communication terminal 10 (A).

  The communication terminal 10 (A) analyzes the received “Error Code YYY” message. Then, the communication terminal 10 (A) reads the display content 810 corresponding to the analyzed error type from the storage unit 124, and displays the read display content 810 on the display unit 128.

  Thereby, the communication terminal 10 (A) notifies the user of the communication terminal 10 (A) that the communication terminal 10 (B) cannot receive the content. The display content 810 includes options for selecting subsequent processing according to the type of error. The communication terminal 10 (A) can make the user of the communication terminal 10 (A) easily select the subsequent process according to the type of error.

  The display content 810 includes an option of whether to transmit the content again. When the user of the communication terminal 10 (A) selects to transmit the content again, the communication terminal 10 (A) transmits a “SIP INVITE” message to the communication control server 22 (A). Subsequently, each process for transmitting the content is performed. Note that any one of the communication control server 22 (B), the communication control server 22 (A), and the communication terminal 10 (A) may detect an error and issue “Error Code YYY”.

  FIG. 9 shows an example of error processing by the communication terminal 10 (A). Here, a case where content cannot be transmitted to the communication terminal 10 (B) will be described. The case where the content could not be transmitted to the communication terminal 10 (B) may be a case where an error has occurred in the communication terminal 10 or the like while transmitting the content. In addition, when the communication session times out while transmitting the content, the storage area of the communication terminal 10 (B) may be full when transmitting the content.

  The communication terminal 10 (A) transmits the designated content data using the “MSRP SEND” message from the state where the peer-to-peer session and the TCP connection with the communication terminal 10 (B) are established. The communication terminal 10 (B), which has detected that the content is not transmitted, sends a “SIP BYE (failure)” message to that effect via the communication control server 22 (B) and the communication control server 22 (A). 10 (A).

  The communication terminal 10 (A) analyzes the received “SIP BYE (failure)” message. For example, the communication terminal 10 (A) specifies that the error type is an error indicating that the transmission of the content has failed by using the Reason Header of the “SIP BYE (failure)” message. In addition, information indicating that a call is automatically executed is recorded in the communication terminal 10 (A). For this reason, the communication terminal 10 (A) automatically executes a voice call through the circuit switching network without transmitting the content. That is, a “SETUP” message is transmitted to the circuit switch (A) to make a call, and subsequently, each process for performing a voice call with the communication terminal 10 (B) is performed.

  When information indicating that the call is not automatically executed is recorded, the communication terminal 10 (A) determines whether to execute the call without automatically executing the voice call. A selection screen for selecting can be displayed on the display unit 128. Communication terminal 10 (A) may display a selection screen on display unit 128 for selecting whether or not to retransmit the content. Note that any of the communication control server 22 (B), the communication control server 22 (A), and the communication terminal 10 (A) may detect an error and issue “SIP BYE (failure)”.

  10, FIG. 11, and FIG. 12 show an example of a timer processing flow by the communication terminal 10 (A). The communication terminal 10 (A) transmits a request message (“SIP INVITE” message) for starting a session for communicating content to the communication terminal 10 (B), and then activates the first timer 141 (S1001). ). It is determined whether or not a response message (“200 OK (INV)” message) to the request message (“SIP INVITE” message) has been received from the communication terminal 10 (B) (S1002).

  If it is determined in step S1002 that the data has not been received (S1002: No), it is determined whether or not the first timer 141 has timed out (S1003). If it is determined in step S1003 that a timeout has occurred (S1003: Yes), a “SIP BYE (Cancel)” message is transmitted to the communication terminal 10 (B) (S1004). An error is displayed on the display unit 128 (S1005), and the timer process is terminated.

  If it is determined in step S1103 that the second timer 142 has not been received (S1103: No), it is determined whether the second timer 142 has timed out (S1104). If it is determined in step S1104 that a timeout has occurred (S1104: Yes), an error is displayed on the display unit 128 (S1105). A “SIP BYE (failure)” message is transmitted to the communication terminal 10 (B) (S1106), and the timer process is terminated. If it is determined in step S1104 that the timeout has not occurred (S1104: No), the process returns to step S1103 and the timer process is continued.

  If it is determined in step S1103 that the message has been received (S1103: Yes), it is determined whether or not a “SuccessReport” message has been received from the communication terminal 10 (B) (S1107). If it is determined in step S1107 that it has not been received (S1107: No), it is determined whether a “FailureReport” message has been received from the communication terminal 10 (B) (S1108). If it is determined in step S1108 that the message has been received (S1108: Yes), an error is displayed on the display unit 128 (S1109), and the timer process ends.

  If it is determined in step S1108 that the second timer 142 has not been received (S1108: No), it is determined whether the second timer 142 has timed out (S1110). If it is determined in step S1110 that a timeout has occurred (S1110: Yes), an error is displayed on the display unit 128 (S1111). A “SIP BYE (failure)” message is transmitted to the communication terminal 10 (B) (S1112), and the timer process ends.

  If it is determined in step S1110 that the timeout has not occurred (S1110: No), the process returns to step S1107 and the timer process is continued. If it is determined in step S1107 that the message has been received (S1107: Yes), the second timer 142 is stopped (S1113), and the process proceeds to step S1201.

  The third timer 143 is started (S1201). A “SETUP” message is transmitted to the communication terminal 10 (B) (S 1202). It is determined whether or not the “SIP BYE” message transmitted from the communication terminal 10 (B) has been received (S1203).

  In step S1203, when it is determined that the data has not been received (S1203: No), it is determined whether the third timer 143 has timed out (S1204). If it is determined in step S1204 that a timeout has occurred (S1204: Yes), an error is displayed on the display unit 128 (S1205). A “BYE (Failed)” message is transmitted to the communication terminal 10 (B) (S1206), and the timer process is terminated.

  FIG. 13 shows an example of an image display method by the communication terminal 10 (B). An image 1300 indicates an image generated from image data included in the content transmitted from the communication terminal 10 (A). Model A and model B are examples of the communication terminal 10 (B).

  The model A has a screen having a size larger than the image size of the image 1300. The model A displays the image 1300 on the display unit 128 without changing the size of the image 1300. The model B has a screen having a size smaller than the image size of the image 1300. The model B displays the image 1300 on the display unit 128 after reducing the size of the image 1300.

  The communication terminal 10 (B) may change the aspect ratio of the image 1300 according to the aspect ratio of the screen on which the image 1300 is displayed. The communication terminal 10 (B) may enlarge the image 1300 according to the size of the screen on which the image 1300 is displayed.

  FIG. 14 shows an example of a method for displaying an incoming call history by the communication terminal 10 (B). A screen 1401 displayed on the display unit 128 of the communication terminal 10 (B) is a screen that displays an incoming call history.

  The screen 1401 includes an icon 1411, an icon 1421, and an icon 1422. Icon 1411 and icon 1422 indicate that content has been received. The calls received from “Mr. Oi” and “Mr. Doi” indicate that the content is included. Icon 1422 indicates that the telephone call could not be answered. It is shown that he was unable to answer the incoming phone call from “Mr. Doi”.

  The communication terminal 10 (B) stores the content received from the communication terminal 10 (A) in association with the incoming call history. The communication terminal 10 (B) holds a table in which correspondences between incoming call history, a flag indicating presence / absence of content, and a file name of the content are stored. The communication terminal 10 (B) can reproduce the read content by reading the content from the table even when the communication terminal 10 (B) cannot communicate with another communication terminal.

  When the icon 1411 is selected by the user of the communication terminal 10 (B), the communication terminal 10 (B) refers to the table, and the content associated with the icon 1411, that is, “Mr. Ooi”. The content transmitted from the communication terminal 10 (A) is read from the table. Then, the communication terminal 10 (B) reproduces the read content. The communication terminal 10 (B) may store the content transmitted to the other communication terminal 10 in association with the transmission history.

  FIG. 15 shows an example of an incoming call rejection process by the communication terminal 10 (B). Here, a case where the communication terminal (A) is registered in the incoming call rejection list of the communication terminal 10 (B) will be described. When the communication terminal 10 (A) specifies the content to be transmitted and receives a call instruction to the communication terminal 10 (B), the communication terminal 10 (A) sends a “SIP INVITE” message to the communication control server 22 (A) and the communication control server 22. It transmits to communication terminal 10 (B) via (B).

  The communication terminal 10 (B) extracts the content transmission terminal identification information included in “SIP INVITE” at the timing of receiving the “SIP INVITE” message (timing T 1 shown in FIG. 4). Then, the communication terminal 10 (B) determines whether the extracted content transmission terminal identification information matches the incoming call rejection terminal identification information stored in the storage unit 124. If it is determined that the content transmission terminal identification information matches the incoming call rejection terminal identification information, the communication terminal 10 (B) sends a “480 Temporary Unavailable” message, which is a rejection message for the “SIP INVITE” message, to the communication terminal 10 (A ).

  The communication terminal 10 according to the present embodiment has a function of refusing reception of content from a designated transmission source, thereby suppressing wasteful transmission / reception of content with the designated transmission source. Further, unnecessary contents can be prevented from being stored in the storage unit 124.

If it is determined in step S1610 that a time-out has occurred (S1610: Yes), a “SIP BYE (failure)” message is transmitted to the communication terminal 10 (A) (S1611), and the timer process ends. If it is determined in step S1610 that the timeout has not occurred (S1610: No), the process returns to step S1609 and the timer process is continued.

  If it is determined in step S1609 that it has been received (S1609: Yes), the fourth timer 144 is stopped (S1612). A “200 OK (SEND)” message is transmitted to the communication terminal 10 (A) (S 1607), and the process proceeds to step S 1701.

  It is determined whether or not the content transmitted from the communication terminal 10 (A) is an acceptable file (S1701). If it is determined in step S1701 that the file is not acceptable (S1701: No), an “MSRP Error” message is transmitted to the communication terminal 10 (A) (S1702). A “SIP BYE (failure)” message is transmitted to the communication terminal 10 (A) (S 1703), and the timer process ends.

  If it is determined in step S1701 that the file is acceptable (S1701: Yes), a “Success Report” message is transmitted to the communication terminal 10 (A) (S1704), and the fifth timer 145 is started. (S1705). It is determined whether or not the “SETUP” message transmitted from the communication terminal 10 (A) has been received (S1706).

  In step S1706, if it is determined that the data has not been received (S1706: No), it is determined whether the fifth timer 145 has timed out (S1707). If it is determined in step S1707 that a timeout has occurred (S1707: Yes), a “SIP BYE (failure)” message is transmitted to the communication terminal 10 (A) (S1708), and the timer process is terminated. If it is determined in step S1707 that the timeout has not occurred (S1707: No), the process returns to step S1706 and the timer process is continued.

  If it is determined in step S1706 that the message has been received (S1706: Yes), it is determined whether the user is the corresponding user (S1709). If it is determined in step S1709 that the user is not the user (S1709: No), a predetermined incoming call operation is performed (S1710), the process returns to S1706, and the timer process is continued. If it is determined in step S1709 that the user is the user (S1709: Yes), an “ALERTING” message is transmitted to the communication terminal 10 (A) (S1711), and the fifth timer 145 is stopped (S1711). .

  A “SIP BYE (success)” message is transmitted to the communication terminal 10 (A) (S1712). The content file transmitted from the communication terminal 10 (A) is saved (S1713). The content file transmitted from the communication terminal 10 (A) is reproduced (S1714), and the timer process is terminated.
