MMS system to support message based applications

摘要

Sending apparatus, receiving apparatus, sending method, receiving method and sending and receiving system for supporting application based MMS. The body of an incremental MMS includes a dynamic data section of MMS, a static data indicator associated with the MMS, and a link tag between indicated static data and the dynamic data. The amount of the message quantity transmitted may be reduced because the changed section of the incremental MMS is sent directly via short message channel in dynamic data mode. In turn, the incremental MMS may be sent via short message channel instead of MMS channel due to the reduction of transmitted message, which further reduces the communication cost.

1. A sending apparatus for supporting application based Multimedia Messaging Service (MMS) comprising:
an MMS server for generating ordinary and incremental MMS messages and comprising an incremental update component for assembling an incremental MMS message by providing a body of the incremental MMS message including a dynamic data section of the incremental MMS message containing only a changed part from an original MMS message, a static data indicator associated with the incremental MMS message, and a link tag between indicated, non-changed static data from the original MMS and the dynamic data, wherein the link tag describes how to merge the dynamic data from the incremental MMS into the original MMS to replace part of the original MMS according to the dynamic data, the static data indicated by the static data indicator and the link tag, and to thereby generate a new ordinary MMS message; sending means comprising more than one sending channel: a determining means for determining whether an MMS message to be sent is an incremental MMS message or an ordinary MMS message, wherein the body of the incremental MMS message includes the dynamic data section of the incremental MMS message containing only the changed part from the original MMS message, the static data indicator associated with the incremental MMS message, and the link tag between the indicated, non-changed static data from the original MMS and the dynamic data; a size comparison means for determining a size of the incremental MMS message to be sent and for comparing the size to a predefined threshold; and a sending channel selector for selecting a sending channel on basis of the size of the incremental MMS message to be sent.
