Abstract

The embodiment of the invention discloses a method for disposing lost packet, a method for controlling transmission quality, a device and a system thereof. The method for disposing lost packet comprises: calculating the congestion packet loss rate according to the total packet loss rate of the first grouped data packet, the total packet loss rate of the second grouped data packet, as well as the currently stored ratio of the wireless packet loss rate of the first grouped data packet and the wireless packet loss rate of the second grouped data packet in the first statistic window; comparing the calculated congestion packet loss rate with a preset threshold value, if the congestion packet loss rate is larger than the threshold value, judging the lost packet in the first statistic window is the congestion packet, and if the congestion packet loss rate is smaller than the threshold value, judging the lost packet in the first statistic window is the wireless packet. The adoption of the embodiment of the invention can improve accuracy in judging the category of the lost packet.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for processing packet loss, a transmission quality control method, device and system. Background technique [0002] The emergence of various real-time multimedia applications in mobile networks and the connection between mobile users and the Internet require the support of Quality of Service (QoS, Quality of Service) in future mobile networks. In current and future wireless mobile networks, the provision of many wireless services is based on the integration of wireless communication networks and the Internet. The analysis of this type of network shows that the packet loss generated by the system includes: ① packet loss caused by congestion in the wired network; ② wireless random errors (including transmission errors in wireless links (affected by fading, multipath and shadowing); impact) caused by packet loss or bit errors). And in the two networks (wired and wireless), the c...
