In the beginning process (A1 step among Fig. 4), attachment viewer browser plug-in (" DocView ") oneself registration (A2 step) tentation data stream content type is as Versatile content stream (UCS).According to preferred embodiment, browser plug-in is to browser registration " application/vnd.company.ucs " content type, to such an extent as to browser just adds " application/vnd.company.ucs " and arrives " acceptance " head when asking HTTP URL.
The secure communication pipeline that mobile data service (MDS) 5 forms between mobile device 3 and server (as Web server 9A, 9B etc.) and the attachment server 7.MDS 5 is as HTTP with property and TCP/IP agency.MDS 5 comprises the UCS code converter, own registration (B1 step among Fig. 4 B) attachment server 7 supports when it starts all MIME content types (as " application/ms-word "; " application/ms-excel ", or the like) (B2 step among Fig. 4 B).7 pairs of annexes of attachment server carry out document and are transformed into suitable form, so that send to equipment 3 and show.For example, if annex is MS
Figure A20058005180200071
Document, attachment server 7 is carried out the Binary Conversion of document, to be transformed into the UCS form that is suitable for wireless transmission.The UCS form is supported text, image, vector sum mixed content.Content of text keeps some in its initial format, as runic, and italic and underscore, but UCS rich text (rich text) file is than original document little a lot (for example, 10% of the original document size).
Following content type is registered by the MDS code converter:
Content type Application program
Application/msword Microsoft Word
Application/vnd.ms-excel Microsoft Excel
Application/vnd.ms-powerpoint Microsoft PowerPoint
Application/pdf Adobe PDF
Application/wordperfect5.1 Corel Word Perfect5.1
