The third embodiment:
the invention mainly aims to fuse and reconstruct a plurality of accessories in a multimedia message into a multipart/related (data type) file without changing the accessory content of the multimedia message when a multimedia message center processes the multimedia message with a plurality of accessories, the data type of the original accessory content is changed, a new file hierarchy structure has two layers, an accessory analyzer can be analyzed and restored into the original plurality of accessories according to the hierarchy for display, the accessories are fused into a file, the transmission, the management and the storage are convenient, and meanwhile, the IO consumption is reduced and the processing performance of the multimedia message center is improved due to the reduction of the number of read-write files in the storage operation process.
Multimedia message attachments sent by a CP/SP or a mobile phone terminal usually only have a layer of MIME coding structure, each attachment has respective data type and attribute, after being divided and analyzed, each attachment can be stored into a file, and read-write operation of a plurality of files can be generated, so that not only is IO consumption increased, but also transmission, management and storage are inconvenient due to excessive file quantity.
In the prior art, in the process of using the MIME protocol, user data and attachments are usually simply encoded according to the MIME protocol without changing the data types of the attachments, the attachment encoding hierarchy has only one layer, and each attachment is a separate file.
The invention provides a method for processing multimedia message attachments by a multimedia message center, which takes a multilevel type file as a multipart/related type file as an example for explanation. When the multimedia message center processes multimedia messages of multiple attachments, the attachments are extracted and then reconstructed, under the condition that the Content of the original attachments is not changed, the multiple attachments are reconstructed into a multipart/related Type file, a Content-Type (data Type) is defined in the file as multipart/related, a new boundary is a first segment identifier 1, the boundary is used for dividing the attachments, each attachment has a respective Content-Type and Content, each attachment is an independent file relative to the original attachment, and the multiple attachments are nested in the multipart/related Type file and are of a two-layer structure.
The file of the type can be normally analyzed and restored by the mobile phone to be displayed as a common multimedia message accessory, the multimedia message center can store all accessory contents by only generating one file in the process of processing the multimedia message, when a mobile phone user downloads the multimedia message contents, the multimedia message center reads user data and the reconstructed file and carries out MIME coding, a boundary which is a second segment identifier 2 is defined in the coding process to divide the user data and the accessory, the file is transmitted to the mobile phone terminal after the coding is finished, and the mobile phone terminal analyzes and displays the accessory.
Because the number of read-write files is reduced in the process of processing the multimedia message by the multimedia message center, the IO consumption is reduced, the processing performance of the multimedia message center is improved, and the optimization cost is low because the expenditure of hardware equipment is not increased.
The invention provides a multimedia message processing method, which is used for processing multimedia message accessories, facilitates the transmission, management and storage of the accessories, reduces IO consumption in the storage process and improves the processing performance of a multimedia message center.
