The multimedia message arrival alert message includes the caller's phone number and the message ID and header information of the multimedia message.
How the arrival of a multimedia message is indicated by a multimedia message arrival alert message containing a preview page of the multimedia message is described hereinafter.
Once a multimedia message arrival alert message is received, the control unit 11 alerts the arrival of a multimedia message by outputting an alert sound through the audio processing unit 15. At this time, the multimedia message arrival alert message may include a preview page (e.g., the first page or the smallest size page of the incoming multimedia message). However, the present invention is not limited therein. Next, the control unit 11 instructs the display unit 16 to display a query message asking whether to receive the multimedia message. If a reception confirmation command is input through the input unit 12 in response to the query message, the control unit 11 instructs the display unit 16 to display the preview page
The control unit 11 determines whether to download the remaining pages according to a user command input through the input unit 12. When the user command is a download confirmation command, the control unit 11 downloads the remaining pages of the multimedia message. Otherwise, if the user command is a download cancel command, the control unit 11 rejects the downloading the remaining pages of the multimedia message. That is, when a predetermined display time of the preview page has expired or a navigation command for viewing the next page is input, the control unit 11 displays a query message asking whether to download the remaining pages of the multimedia message. If a user command is input while the query message is displayed, the control unit 11 processes the multimedia message according to the user command.
The query message is provided with “display next page”, “display selected page”, “display whole pages”, and “reject download” options. When the “display next page” option is selected by the user, the control unit 11 requests the next page of the preview page from the MMSC 20. When the “display selected page” option is selected, the control unit 11 requests the selected page of the multimedia message from the MMSC 20. When the “display whole pages” option is selected, the control unit 11 requests the remaining pages of the multimedia message from the MMSC 20. In the meantime, when the “reject download” option is selected, the control unit 11 requests that the MSC 20 discard the remaining pages of the multimedia message.
How the arrival of a multimedia message is indicated by a multimedia message arrival alert message having no preview page of the multimedia message is described hereinafter.
Once a multimedia message arrival alert message is received, the control unit 11 alerts the arrival of a multimedia message by outputting an alert sound through the audio processing unit 15. Next, the control unit 11 instructs the display unit 16 to display a query message asking whether to receive the multimedia message. If a reception confirmation command has been input through the input unit 12 in response to the query message, the control unit 11 requests the multimedia message from the MMSC 20. The multimedia message can be requested by page such that only the pages selected by the user are downloaded.
At this time, the multimedia message arrival alert message may include a caller's phone number and the message ID and header information of the multimedia message. The header information may include the page information for creating blank pages. When the reception confirmation command is input, the control unit 11 creates blank pages on the basis of the page information contained in the multimedia message arrival alert message and displays the blank pages on the display unit 16. The blank pages are displayed by page and in the form of a thumbnail or text message. The blank pages are provided with page numbers and information about content type such as video, audio, and text. The content type can be indicated in the form of a text or icon.
Once at least one blank page is selected on the display unit 16, the control unit 11 requests the page corresponding to the selected blank page from the MMSC 20. Next, the control unit 11 replaces the blank page with the original page downloaded from the MMSC 20. At this time, the blank pages can be selected in sequential order or randomly.
When the downloaded pages are displayed in the form of thumbnail images or text and the user selects one of the thumbnail images or text, control unit 11 displays the selected page in the form of a full screen image. The control unit 11 allows the user to confirm whether to download the remaining pages that are not received yet with reference to the contents previewed in the full screen image. The above described multimedia message processing functions can be specified in the User Agent Profile (UAProfile) of the mobile terminal 10. For example, the UAProfile specifies that the mobile terminal 10 supports “per-MMS SMIL page download” feature.
Multimedia Message Processing Method
FIG. 3 is a flowchart illustrating a multimedia message processing method according to an exemplary embodiment of the present invention.
Referring to FIGS. 1 to 3, the mobile terminal 10 first receives a multimedia message arrival alert message (S51). The multimedia message arrival alert message contains a preview page of the multimedia message and is transmitted by the MMSC 20. Preferably, the UAProfile of the mobile terminal 10 specifies that the mobile terminal 10 supports “per-MMS SMIL page download” capability. The MMSC 20 checks the UAProfile of the mobile terminal 10 to determine whether the mobile terminal 10 supports “per-MMS SMIL page download” capability before sending the multimedia message arrival alert message. When it is determined that the mobile terminal 10 supports “per-MMS SMIL page download” capability, the MMSC 20 sends the multimedia message arrival alert message containing the preview page of the multimedia message. The multimedia message arrival alert message also contains the caller's phone number, the message ID and the header information of the multimedia message. The control unit 11 saves the multimedia message arrival alert message in the memory unit 13. In the meantime, when the mobile terminal 10 does not support “per-MMS SMIL page download” capability, the MMSC 20 performs a normal MMS message processing procedure.
Once the multimedia message arrival alert message is received, the control unit 11 instructs the display unit 16 to display a query message asking whether to receive the multimedia message (S53). At this time, the control unit 11 instructs the audio processing unit 15 to output an alert sound to indicate the arrival of the multimedia message.
If a reception confirmation command is input in response to the query message, the control unit 11 instructs the display unit 16 to display a preview page carried by the multimedia message arrival alert message (S55). Next, the control unit 11 determines whether a predetermined display time has expired or a next page view command is input (S57).
If the display time has not expired and no next page view command is input, the control unit 11 maintains the display of the preview page.
Otherwise, if the display time has expired or the next page view command is input, the control unit 11 instructs the display unit 16 to display the remaining pages processing options on the display unit 16 (S59). The control unit 11 detects a user selection on one of the remaining pages processing options (S61) and processes the remaining pages of the multimedia message according to the selected multimedia processing option (S63). The control unit 11 displays the remaining pages processing options after notifying the user that there are pages that are not downloaded yet.
The remaining pages processing options include “display next page”, “display selected page”, “display whole pages”, and “reject download” options. If the “display next page” option is selected at step S61, the control unit 11 requests the next page following the preview page from the MMSC 20. If the “display selected page” option is selected, the control unit 11 requests the selected page of the multimedia message from the MMSC 20. If the “display whole pages” option is selected, the control unit 11 requests the remaining pages of the multimedia message from the MMSC 20. In the meantime, if the “reject download” option is selected, the control unit 11 requests that the MSC 20 discard the remaining pages of the multimedia message without downloading the remaining pages.
In more detail, if the user selected the “display next page” option, the control unit 11 requests that the MMSC 20 send the page following the preview page. Upon receipt of the request from the mobile terminal 10, the MMSC 20 sends the next page with the message ID. In the case that the page received from the MMSC 20 has the same message ID as the previously received message, the control unit 11 combines the currently downloaded page with the previously received page and stores the combined pages as a single multimedia message.
In the meantime, if the user selected the “reject download” option, the control unit 11 ends the multimedia message processing. At this time, the control unit 11 may save the multimedia message arrival alert message itself or only the log data such as the caller's phone number extracted from the multimedia message arrival alert message.
FIG. 4 is a flowchart illustrating a multimedia message processing method according to another exemplary embodiment of the present invention.
Referring to FIGS. 1, 2, and 4, the mobile terminal 10 receives a multimedia message arrival alert message which indicates the arrival of a multimedia message (S71). The multimedia message arrival alert message includes the caller's phone number and the message ID and header information. The control unit 11 stores the multimedia message arrival alert message within the memory unit 13.
Upon receipt of the multimedia message arrival alert message, the control unit 11 instructs the display unit 16 to display a query message asking whether to receive the multimedia message (S73). At this time, the control unit 11 also instructs the audio processing unit 15 to output an alert sound for indicating the arrival of the multimedia message.
If a reception confirmation command is input in response to the query message, the control unit 11 creates blank pages corresponding to actual pages constituting the multimedia message on the display unit 16 with reference to the header information of the multimedia message (S75). The blank pages can be presented in the form of thumbnail images.
Next, the control unit 11 determines whether a page selection command is input for selecting at least one of the blank pages (S77). If a page selection command is input, the control unit 11 requests the page corresponding to the at least one blank page indicated by the page selection command from the MMSC 20 (S79). At this time, the user can select the blank pages in sequential order or randomly.
Next, the control unit 11 downloads the selected pages from the MMSC 20 and displays the downloaded page in place of the corresponding blank page (S81). At this time, if the user selects the downloaded page by means of the input unit 12, the control unit 11 presents the selected page in full screen. Next, the control unit 11 repeats step S77 for downloading the remaining pages of the multimedia message in accordance with the user's intention.
In the meantime, if a reception rejection command is input in response to the query message at step S73, the control unit 11 ends the multimedia message processing procedure. At this time, the control unit 11 may save the multimedia message arrival alert message or only log data such as the caller's phone number contained in the incoming MMS.
If no page selection command has been input within a predetermined time (i.e. no blank page is selected) at step S77, the control unit 11 determines whether a download rejection command is input (S83). If a download rejection command has been input, the control unit 11 ends the multimedia message processing procedure. Otherwise, if the download cancel command has not been input within a predetermined time, the control unit 11 maintains displaying the blank pages.
Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and/or modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
As described above, the multimedia message processing method of the present invention allows a user to determine whether to download the entire multimedia message after viewing a preview page carried by a multimedia message arrival alert, thereby avoiding download of unwanted multimedia message, resulting in reduction of data service cost and improvement of memory utilization.
Although the present disclosure has been described with an exemplary embodiment, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
