specific Embodiment approach

[0042] In Embodiment 2 of the present invention, a specific implementation of a streaming media transmission method is as follows:

[0043] The access network sets the period for the terminal to report the receiving buffer status during the establishment of the streaming media service, and can further set a threshold value, and the threshold value can include a high threshold value and a low threshold value. The terminal immediately reports the receiving buffer status to the access network after the streaming media service is established. The status mainly includes Buffer size (cached length) such as 2Mbyte (megabytes), and Usage (occupancy rate) such as 60%. Among them, the schematic diagram of cache length and occupancy rate is as follows image 3 shown.

[0044]Thereafter, the terminal reports the status of the receiving buffer according to the period set by the access network. When the access network sets the threshold, the terminal also needs to report immediately when...

Abstract

The invention discloses a transmission method for stream media, comprising the following steps of: receiving a status of a terminal-on reception cache reported by a terminal; adjusting a stream media transmission policy for the terminal in accordance with the status of the reception cache. The invention also discloses an apparatus for controlling transmission of the stream media. By using the invention, an access network side can dynamically adjust sending policy of stream media data according to the status of the reception cache reported by the terminal, thus remarkably improving utilization rate of stream media traffic wireless resources and enhancing system capacity.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a streaming media transmission method and equipment. Background technique [0002] Streaming media service is a multimedia application developed from the Internet, which refers to multimedia files transmitted on the network using streaming (Streaming), including audio, video and animation. Mobile streaming media service is the application of streaming media technology on mobile networks and terminals. It mainly uses the current 2.5G or 3G mobile communication network to provide audio and video streaming media services for mobile terminals. The contents of mobile streaming media services include news information, film and television, MTV, sports, education, industry and special applications, etc. [0003] The main feature of streaming media transmission technology is to transmit multimedia data in the form of streaming. After compressing the continuous image and sound informati...
