The displaying contents initialization step mainly solves screen content and organizes problem.In order to reduce the content of transmission, the present invention has stipulated a kind of special screen content storage architecture, as far as possible with the screen content modularization.The present invention is divided into following several logical gates with the terminal screen content, and every part all can represent with the form of XML file, and these logical gates only are a kind of giving an example, and the present invention never is limited to this logical partitioning scheme.
1) resource file is described: which file is whole terminal screen content comprise altogether, the type of file, and the final updating date of file, for example: filename: FileDescription.xml
Concrete form is as follows:
<files>
<filename>GlobalSetting.xml</filename>
<filename>Module1Description.xml</filename>
<filename>Module1Content.xml</filename>
<filename>images/picture1.jpg</filename>
<filename>images/picture2.jpg</filename>
<filename>program/widget1.wgt</filename>
<filename>program/widget2.wgt</filename>
</files>
<lastupdate>
<time>20100210</time>
<time>20100310</time>
<time>20100205</time>
<time>20100211</time>
<time>20100211</time>
<time>20100211</time>
<time>20100211</time>
</lastupdate>
Time below corresponding one of each file, the time the form of date show.
2) screen content layout: demonstration and the location logic of the module that comprises in the setting of the screen overall situation and the screen, for example:
Filename: GlobalSetting.xml
Form is as follows:
<background>
<color>blue</color>
<picture>picture2.jpg</picture>
</background>
<modulel>
<name>header</name>
<position>
<top>10</top>
<left>20</left>
</position>
<size>
<width>30px</width>
<height>100px</height>
</size>
</modulel>
3) module Show Styles: the demonstration of each module is set, comprises the edge, font, framing mask, listings format etc., for example:
Filename: ModulelDescription.xml, form is as follows:
<font>
<font-family>Arial，Helvetica，sans-serif</<font-family>>
<font-size>l2px</font-size>
<font-color>#f6f6f6</font-color>
<font-weight>bold</font-weight>
</font>
<table1>
<text-align>left</text-align>
<vertical-align>bottom</vertical-align>
<background>url(../images/picture2.jpg)</background>
<content-number>content1</content-number>
</table1>
4) module contents: record file or content of multimedia in each module, for example:
Filename: ModulelContent.xml, form is as follows:
<content?1>Hello，world！</content1>
<content2>Hello，world！2</content2>
<content3>Hello，world！3</content3>
The principle of renewal terminal screen of the present invention exemplarily is described purely below in conjunction with four above-mentioned logical gates.File is described part and is belonged to definition property file, and it has defined the included all files of content that should show on the terminal screen, such as picture1.jpg, widget1.wgt etc.In the lastupdate mark, defined respectively the update time of these files.The screen content architecture definition background color, display position and the size of each logical gate (that is, picture and little (Widget)).Whether module show is described the concrete display mode that has defined each logical gate, and whether frame is for example arranged, in form and font and alignment thereof etc.Module contents has defined content of multimedia, file or the character string etc. of quoting.
Server end is at first checked file and is described part when more new terminal shows, checks whether there is new file (that is, new logical gate).If do not increase new file, then check existing file such as picturel.jpg and whether change, for example check the date of corresponding picture1.jpg among the lastupdate.
Next, suppose picture1.jpg to occur to change and any variation does not appear in other logical gates, then server end only sends to terminal with new picture1.jpg and FileDescription.xml, the terminal basis is update instruction accordingly, replaces the old picture1.jpg that is showing with new picture1.jpg.Certainly more various variation also may occur, this paper just no longer describes in detail.
Above content be the present invention adopt to content carry out modular one for example, those skilled in the art are understood that by reading this instruction, the invention is not restricted to adopt this mode that displaying contents is carried out modularization, but can adopt various arbitrarily modes to carry out modularization.As long as the division of teaching contents that can show becomes a plurality of modules, and judged by server end and should send the module which will upgrade, so with regard to thought according to the invention.
In terminal screen update content determining step, in order to improve efficiency of transmission, realize transmitted in both directions (terminal use initiatively initiates screen updates, server end and initiatively initiates screen updates), the present invention has designed a kind of take the screen content transmission plan of Session Initiation Protocol as the basis.
Fig. 2 shows the flow process that the terminal use initiatively initiates screen updates:
1) terminal selects to report server end by subscribe message with the personalization of oneself;
2) server end is issued to terminal by the message body among the notification with the XML file that newly configures; At this, terminal also can send the HTTP request, removes to obtain the logical gate that needs renewal;
3) terminal is upgraded terminal screen according to new XML file.
According to a unshowned embodiment, the flow process that server end is initiatively initiated screen updates is as follows:
1) terminal at first is registered on the server end;
2) server end has renewal available by the message body proactive notification terminal of the notification in the Session Initiation Protocol;
3) terminal sends the HTTP request, obtains the logical gate that needs renewal from server end;
4) terminal is upgraded terminal screen according to new XML file.
Generally speaking, the present invention has the following advantages:
1, by adopting Session Initiation Protocol, can distinguish different users according to user's registration message, thereby will be the personalized screen of each customization.
2, by the XML file is carried in the sip message, thereby the strong characteristics of sip message passing fire wall ability have been utilized.
3, by screen content is broken, can then assemble flexibly screen display, the content of minimized transmission screen updates.
Specific embodiment described herein only is to illustrating that the present invention's spirit is done.Those skilled in the art can make various modifications or replenish or adopt similar mode to be substituted described specific embodiment, but can not depart from spirit of the present invention or surmount the defined scope of appended claims.
