Embodiment Construction

[0039] figure 1 The flow chart of the first embodiment of the rate adaptation method provided by the embodiment of the present invention; figure 1 As shown, this embodiment includes:

[0040] Step 110, PSS Server judges whether to adjust the rate;

[0041] Step 112, if the rate needs to be adjusted, the PSS Server sends a rate adjustment notification message to the UE, and the rate adjustment notification message is used by the UE to adjust QoS.

[0042] figure 2 The flow chart of the second embodiment of the rate adaptation method provided by the embodiment of the present invention; figure 2 As shown, this embodiment is based on the PSS system, including two network elements, PSS Server and PSS Client, wherein the PSS Server not only performs rate adaptation decision-making but also performs rate adaptation, and its rate adaptation process specifically includes:

[0043] Step 210, the Real-time Transport Protocol (RTP) stream before the transmission rate adaptation betw...

Abstract

The invention discloses a rate adaption method, a rate adaption device and a rate adaption system. The rate adaption method comprises that: a PSS Server judges if rate regulation is needed; and if rate regulation is needed, the PSS Server sends a rate regulation notification message to a user side, wherein the rate regulation notification message is used for instructing the user side to regulate the quality of service (QoS) of a network. The system comprises the rate adaption device and the user side. In the embodiment of the invention, the user side can dynamically regulate the QoS according to the change of the rate on the server side, so potential resource waste and transmission congest are avoided; and a QoS mechanism of an IMS is multiplexed, the end-to-end QoS transmission is realized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a rate adaptation method, device and system. Background technique [0002] IPTV is a brand-new technology that utilizes broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive services including digital TV. Users can enjoy IPTV services at home by using a PC or network set-top box + ordinary TV, or enjoy IPTV services through mobile terminals. IPTV uses Transmission Control Protocol / Internet Protocol (TCP / IP for short) as the bearer protocol to carry out unicast, broadcast or multicast video services, effectively combining the three fields of TV network, telephone network and Internet into one Together, it is the most representative business of triple play integration. [0003] The IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) is a subsystem p...
