Embodiment Construction

[0022] The embodiment of the present invention provides a technical solution for optimizing the quality of wireless streaming media service, which is applied to the LTE system. In the technical solution, the network side device determines the source rate of the video according to the received wireless streaming media playback request, and according to the The chip source rate allocates bandwidth to the user terminal; when the network-side device receives the streaming media MOS score fed back by the user terminal, the network-side device adjusts the bandwidth of the user terminal according to the streaming media MOS score to make the LTE bandwidth allocation more efficient. Reasonable, while reducing the waste of LTE bandwidth resources, the wireless streaming media MOS is guaranteed. Wherein, the wireless streaming media includes audio or / and video.

[0023] The technical solutions in the present application will be described clearly and completely below with reference to the...

Abstract

The invention discloses a method for optimizing quality of service of a wireless streaming medium and a device. The method for optimizing the quality of the service of the wireless streaming medium is applied to a long term evolution (LTE) system and includes that network-side equipment receives a wireless streaming media playing request sent by a user terminal; the network-side equipment confirms a video source bit rate of the wireless streaming media requested to play according to the received wireless streaming media playing request and distributes band width for the user terminal according to the video source bit rate; and when the network-side equipment receives the value of mean opinion score (MOS) of the streaming media fed back by the user terminal, the network-side equipment adjusts the band width of the user terminal according to the value of the MOS of the streaming media. According to the method for optimizing the quality of service of the wireless streaming media and the device, the LTE band width distribution is reasonable, the LTE band width resource waste is reduced, and simultaneously the MOS of the wireless streaming media is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for optimizing the quality of wireless streaming media services. Background technique [0002] With the rapid development of wireless technology, wireless networks and traditional mobile communication networks have become an important part of the Internet. As a new type of network application, streaming media services will be the main components of mobile communication systems (3G (third generation mobile communication), B3G (super third generation mobile communication), 4G (fourth generation mobile communication)). [0003] Since the Internet is a best-effort network, it can only provide a single best-effort transmission service for upper-layer applications, and does not provide any QoS (Quality of Service, quality of service) guarantee for applications. In addition, the high packet loss rate and bit error rate of the wireless cha...
