Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021]The core idea of ​​realizing the present invention is to provide a method for obtaining a resource entity, including the client sending a request message for obtaining a resource entity to the server, the request message carrying the version identifier of the document corresponding to the requested resource entity; the server according to the request The version identification in the message judges that the document corresponding to the requested resource entity has been modified, and transmits the requested resource entity and the version identification of the document corresponding to the requested resource entity to the client or transmits the version identification of the requested resource entity to the document to the client end.

[0022] In addition, if figure 1 As shown, the present invention also provides a schematic d...

Abstract

The present invention provides a method for obtaining a resource entity, the core idea of ​​which is: the client sends a request message for obtaining a resource entity to the server, and the request message carries the version identifier of the document corresponding to the requested resource entity; The version identifier in the message determines that the document corresponding to the requested resource entity has been modified, and transmits the requested resource entity and the version identifier of the document corresponding to the document to the client or transmits the version identifier of the document corresponding to the requested resource entity to the client. In addition, the present invention also provides a server and a client. With the present invention, the requested resource entity is not sent to the client and is only transmitted to the client when the requested resource entity has not changed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for acquiring resource entities, a server and a client. Background technique [0002] In the field of mobile communication, it is often necessary to transmit resources between a mobile client and a server, for example, a mobile client obtains a resource from a server, or transmits a resource to a server, and the transmission of such resources is usually requested in the form of a message. Many mobile communication standards have developed some mechanisms to reduce unnecessary message transmission or reduce the size of the message. Now there is WBXML (Wireless Binary eXtensible Markup Language) specification, which is used to compress Extensible Markup Language (eXtensible Markup Language, abbreviation: XML) document. The IETF (Internet Engineering Task Force) organization also formulated the RFC3320 SigComp (Request For Comments 3320 SigComp) standard to compress...
