  The present invention relates to a mobile communication terminal such as a mobile phone that can communicate via a communication network such as a mobile phone communication network.

  Conventionally, as a method of downloading content from a server on a communication network in a mobile communication terminal such as this type of mobile phone, a method of executing a communication sequence using a communication protocol such as HTTP as described below is widely known. ing. That is, when the user selects a character string or pictograph with an anchor set on the WWW page displayed on the mobile communication terminal, the mobile communication terminal sends an HTTP request to the content providing server designated by the anchor. A content acquisition request such as The content providing server transmits a content acquisition response such as an HTTP response including the content to the mobile communication terminal so as to respond to the content acquisition request. The mobile communication terminal that has received this content acquisition response can expand and display content data included in the content acquisition response or save it in a predetermined folder.

  Recently, a method of executing a communication sequence that is transmitted and received a plurality of times between a mobile communication terminal and a server on a communication network may be adopted so that desired content can be downloaded reliably (non-patent document). 1). This method is a method standardized by OMA (Open Mobile Alliance), which is an industry group related to mobile communication (hereinafter, this method is referred to as “OMA type content providing method”). In this OMA content providing method, a download descriptor file including download information related to a content to be downloaded is first obtained from a server on a communication network prior to downloading the content. This download information is information such as a URI (Uniform Resource Identifier) in which the content to be downloaded is registered, and the type and size of the content. Next, the user confirms the download information, and inputs whether or not to accept the download by operating the mobile communication terminal. When the user accepts the download, the mobile communication terminal transmits a content acquisition request by a communication protocol such as HTTP for the content approved by the user to the content providing server specified by the URI of the download information. .

  FIG. 8 is a sequence diagram illustrating an example of a communication procedure between the mobile phone 10 and the servers 40 and 50 when music content is downloaded while the manner mode is set in the mobile phone 10 having the above configuration. The music content download procedure in this example employs the OMA download procedure described above.

  First, the user operates the mobile phone 10 to activate a browser application, and accesses the content introduction site for music trial listening on the WEB server 40 (steps S1 to S3). By this access, the music content introduction WEB page shown in FIG. 9A is displayed on the screen 17a of the display 17 of the mobile phone 10 (step S4).

  Next, the user confirms the music content introduction page displayed on the screen 17a of the display 17, and performs a predetermined key operation so as to select the title of the music content desired to be listened to (step S5). When the cellular phone 10 accepts this key operation, it transmits an HTTP request as a download information acquisition request to the download server 50 (step S6).

  Upon receiving the HTTP request, the download server 50 reads download information (information such as ObjectURI, file type, file size, etc.) relating to the download of the content desired by the user from the content storage means (content database) (step S7). Then, an HTTP response as a download information response including this download information is generated and transmitted to the mobile phone 10 (step S8).

  Next, when receiving the HTTP response, the mobile phone 10 displays a download confirmation screen created based on the download information as shown in FIG. 9B on the screen of the display 17 (step S9). The user confirms the contents of the download confirmation screen and performs a key operation for download OK. Specifically, an operation of selecting a “YES” key at the bottom of the download confirmation screen is performed. The cellular phone 10 that has received this key operation transmits an HTTP request as a content acquisition request for downloading the content desired by the user to the download server 50 (steps S10 and S11). When this HTTP request is transmitted, a message indicating that the download is in progress and a bar display indicating the progress of the download are displayed on the display 17 of the mobile phone 10 as shown in FIG. 9C. The

  The download server 50 that has received the HTTP request reads the content desired by the user from the content storage means (content database) (step S12). Next, the download server 50 transmits an HTTP response including the content to the mobile phone 10, and when transmission of the HTTP response is completed, transmits a FIN message as a connection request for disconnecting from the mobile phone 10. (Step S13).

  Next, the mobile phone 10 receives the HTTP response and stores the music content file in a predetermined folder. After storing the music file, the mobile phone 10 transmits an HTTP request (InstallNotify) as a download completion notification indicating that the download has been completed to a predetermined URI (InstallNotifyURI) of the download server 50 (step S14). Receiving this download completion notification, the download server 50 returns an HTTP response as a download completion response to the mobile phone 10 (step S15).

  Next, after receiving the download completion response from the download server 50, the mobile phone 10 displays a download completion notification / sound output confirmation screen shown in FIG. 9D, informing the user of the download completion. In spite of the manner mode being executed, the user is immediately inquired whether or not to audition with the speaker 18. Here, when a key operation for requesting a trial listening of the downloaded music content is performed, specifically, a key operation for selecting the “YES” key is performed, the mobile phone 10 performs expansion processing on the downloaded music content data, and the speaker 18. The sound output of the music or the like is started from (Steps S16 to S18). This sound output is performed only for the downloaded sound file instructed by the user, and the sound output of other ring tones is restricted as usual.

  FIG. 10 is a flowchart showing the procedure of sound output control in the sequence of FIG. In the mobile phone 10, when the download of the content from the download server 50 is completed, it is determined whether or not the content includes a sound file such as a song (steps S101 and S102). Here, if the content includes a sound file, a sound output confirmation image that prompts the user whether or not to perform sound output based on the sound file is displayed (step S103). When the user who has seen the sound output confirmation image gives an instruction to output sound, sound output such as music based on the sound file is forcibly output from the speaker 18 regardless of the manner mode (step S105). . The sound output during the manner mode is performed at a minimum volume as an initial setting. Thereby, it is possible to avoid suddenly outputting the sound at a high volume and to suppress the leakage of sound to the surroundings as much as possible. If there are no people around, you can turn up the volume as needed.

  As described above, according to the present embodiment, when a sound file is included in the content downloaded from the download server 50 during execution of the manner mode, the user is prompted to instruct whether or not to output sound based on the sound file. A sound output confirmation screen is displayed on the display 17. By viewing the displayed screen, the user can instruct whether or not to perform the sound output as desired. When a sound output instruction is input by the input device 405 as an instruction input unit including keys or the like so as to perform sound output based on the sound file, sound output based on the sound file is performed regardless of the manner mode being executed. This is forcibly performed from the speaker 18. Therefore, even when the manner mode is being executed, the sound output from the speaker 18 according to the user's request can be output for the sound file included in the content downloaded from the download server 50.

  In the above embodiment, the case where content is downloaded using the OMA method download procedure as shown in FIG. 8 has been described. However, the present invention does not use the OMA method download procedure, and the content is obtained by normal HTTP communication. The same applies to the case of downloading. That is, in the above-described embodiment, unlike normal HTTP communication, the mobile phone 10 acquires download information such as a URI and a file type from the server 50 prior to content download, and sends a download completion notification to the server 50 after content download. Sending. The present invention can be similarly applied to a case where content is downloaded by normal HTTP communication in which download information is not acquired in advance and transmission completion notification is not transmitted in the OMA method.

  Moreover, in the said embodiment, although the sound output control based on the display of a sound output confirmation screen and a user instruction | indication is performed at the timing which received the content containing sound files, such as an incoming melody, it is limited to this timing. is not. For example, when the sound output control based on the display of the sound output confirmation screen and the user instruction is received and the operation for reproducing the received sound file is performed during the manner mode after the content including the sound file is received. You may make it perform to.

  FIG. 11 is a flowchart for executing reproduction control when an operation for reproducing a music file is performed during the manner mode. In the example of this flowchart, the case where the content received via the mobile phone communication network 20 is an HTML file displaying a WEB page for purchasing an incoming melody is shown. The HTML file is received by a normal HTTP communication from the WEB server 40 as a content providing server together with a music file such as a midi (Musical Instruments Digital Interface) file of the incoming melody.

  First, when the mobile phone 20 receives the HTML file (content) including the music file, the mobile phone 20 displays the music content WEB page shown in FIG. 12A corresponding to the HTML file on the screen 17a of the display 17. (Step S201). A predetermined sound icon (symbol 17c in FIG. 12A) indicating that a music file is included is displayed on the WEB page. Here, when the manner mode is not set, the music file (***. Midi) received together with the HTML file is automatically played. However, when the manner mode is set as in this example, the music file ( ***. midi) is not automatically replayed.

The HTML file including the music file is described as follows, for example.
<html>
...
This is a *** song. <br />
<bgsound src = "***. midi"/><br/>
...
<a href="index.html"> Go to TOP </a>
...
</ html>

  In the example of the HTML file, a bgsound element having a src attribute is used to incorporate a music file and is described as “bgsound src”. An object element having a data attribute may be used instead of the bgsound element. In this case, “object data =” ***. Midi ”” is described instead of “bgsound src =” ***. Midi ””. When an HTML file is received and interpretation processing is executed, if there is a description of the bgsound element or object element, the music file specified by those elements is received, and then the WEB page is displayed.

Next, when the user performs a key operation to select “Menu” on the screen displaying the music content WEB page, the cellular phone 20 displays the menu screen shown in FIG. 17a (steps S202 to S203).
Next, when the user performs a playback operation to select “3. Playback” on the menu screen, the mobile phone 20 forcibly executes music playback with sound output even when the manner mode is set. A confirmation screen for music reproduction shown in FIG. 12C for confirming whether or not is displayed is displayed (steps S204 to S205).
Next, when the user performs a key operation to instruct sound output on the music playback confirmation screen, the mobile phone 20 activates the music player application and displays the music player screen shown in FIG. At the same time, the music file (***. Midi) with sound output is forcibly executed. As a result, sound output such as music based on the music file (***. Midi) is forcibly performed from the speaker 18 in spite of the manner mode being set (step S207). The sound output during the manner mode is performed at the minimum volume as in the embodiment of FIG.

  As described above, according to the present embodiment, the user can instruct whether or not to output the sound of the music file as desired by looking at the confirmation screen for music playback displayed on the display 17. When a sound output instruction is input by the input device 405 as an instruction input unit including keys to perform sound output based on the music file, sound output based on the music file is performed regardless of whether the manner mode is being executed. This is forcibly performed from the speaker 18. Accordingly, even when the manner mode is being executed, sound output from the speaker 18 according to the user's wish can be performed for the music file included in the HTML file (content) downloaded from the WEB server 40.
