Abstract

The invention discloses a VoIP communication method and apparatus. The VoIP communication method comprises steps: obtaining the network bandwidth condition of a network which a terminal belongs to in a VoIP communication process of the terminal; determining coding parameters according to the network bandwidth condition; and sending the coding parameters to the terminal so that the terminal reconfigures an encoder for video data coding according to the coding parameters and then sends the parameters. According to the method and apparatus, the technical problem of poor service quality of VoIP is solved, the coding parameters such as resolution, frame rate, and code rate are adjusted according to the network bandwidth condition, network congestion is avoided, and the service quality is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a VoIP communication method and device. Background technique [0002] VoIP (Voice over IP, voice over IP) is a technology that transmits digitized signals in the form of data packets in real time over an IP network. VoIP adopts Internet and global IP interconnection environment to provide better service than traditional business. The VoIP transmission service on the IP network may include services such as voice, video and data. The basic principle of VoIP is to encode and compress digital signals through data compression algorithms, then package these data according to the TCP / IP standard, and distribute the data packages to receiving terminals through the IP network. [0003] In terminals, VoIP calls have been more and more widely used. Quality of Service (QoS) guarantee technology, as one of the key technologies of VoIP, has become more and more important....
