Embodiment Construction

[0027] In order to reduce the packet loss rate at the receiving end, an embodiment of the present invention provides a data packet output processing method. In this method, when the number of compensation data packets continuously output by the receiving end exceeds a preset threshold value, if the currently receiving If the RTP data packet received earliest by the end and not yet output is a data packet to be adjusted that has not arrived at the receiving end at the normal arrival time, it chooses to output the RTP data packet instead of discarding the RTP data packet or outputting a compensation data packet.

[0028] see figure 1 , the data packet output processing method provided by the embodiment of the present invention specifically includes the following steps:

[0029] Step 10: determine whether the number of compensation data packets output by the receiving end exceeds a preset threshold value, the threshold value is a positive integer, and the compensation data packet...

Abstract

The embodiment of the invention discloses an output processing method of data packets, which comprises the following steps: determining whether the number of compensation data packets which are continuously output exceeds the preset threshold value or not by a receiving terminal; when the receiving terminal determines that the number of the compensation data packets exceeds the preset threshold value, determining whether the RTP data packet which is currently received at the earliest and is not output is the data packet to be adjusted or not, wherein the data packet to be adjusted means the data packet in the RTP data packets failing to reach according to the preset time sequence; and when the RTP data packet is determined to be the data packet to be adjusted, outputting the RTP data packet. The embodiment of the invention also discloses an output processing device of data packets. The invention can be used for effectively reducing the packet loss ratio of the receiving terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data packet output processing method and device. Background technique [0002] At present, voice over Internet Protocol (Voice over Internet Protocol, VoIP) technology has been more and more widely used. In short, VoIP is to encapsulate data into packets on Internet Protocol (IP) network delivered in real time. Compared with traditional circuit voice services, the biggest advantage of VoIP is that it can make extensive use of IP interconnection resources, thereby providing more and better services than traditional services. In VoIP voice communication applications, Real-time Transport Protocol (RTP) is a widely used network transmission technology, which provides real-time guarantee for voice data transmission in IP network. [0003] In an IP network, voice data is usually first encapsulated into an RTP message. The RTP header provides features such as the ident...
