Problems solved by technology

If the original cached data is sent to the receiving user at this time, it is undoubtedly a transmission of invalid data, thus wasting system transmission resources
However, for the problem of how to deal with these invalid media data, the existing PoC service specification still does not involve
[0006] It can be seen that the media caching mechanism of the existing application business is not perfect enough. In the case of failure to receive the acknowledgment instruction or taking a long time to receive the acknowledgment instruction due to communication failure, it is likely to seriously affect the quality of the service, and it is impossible to solve the caching problem. The problem of media data failure, resulting in a large waste of system resources

Embodiment Construction

[0029]The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The invention discloses a media data caching method for application services. When a business client or a business server receives media data from a media sender, its main processing idea is: to set the caching time limit for the received media data and perform caching ; Within the cache time limit, when receiving a confirmation receipt indication from the media receiver, the service client or service server sends the media data cached by itself to the media receiver. Through this processing mechanism, each cached media data has its own cache timeliness, thereby ensuring that valid media data is delivered to the media receiver.

[0031] And when the time limit for caching is exceeded, that is, when the cached media data becomes invalid, the method of the present invention basically provides two processing methods: one, the servi...

Abstract

In the invention, when the client side of said service or server of said service receives the media data from the media transmitting side, the method comprises: a the client side or server sets the buffer time limitation for the received media data, and buffers the data; b) in valid buffer time, when receiving the receiving confirmation from the receiving side, the client side or service server sends the media data buffered by itself to the media data receiving side.

Description

technical field [0001] The invention relates to media transmission technology for application services, in particular to a media data caching method and system for application services. Background technique [0002] At present, a media caching mechanism has been introduced in some application services. Simply put, the media sender can send the media data to the to the service client or service server for caching; when the service client or service server receives the acknowledgment receipt indication, then send the cached media data to the media receiver. After adopting such a media cache mechanism, the media data from the media sender will be quickly sent to the media receiver after receiving the receiving confirmation indication, thereby increasing the media transmission speed. A typical service applying such a media caching mechanism is a push-to-talk (PoC) service in a cellular system. This article only takes the PoC service as an example to elaborate on the problems in...
