Problems solved by technology

In the existing technology, users cannot be distinguished to provide voice services with differentiated call quality; after the user call is established, the voice service quality cannot be dynamically adjusted according to changes in the user network; after the user call is established, it cannot be adjusted according to the server load. Changes to dynamically adjust voice service quality
That is to say, the implementation of the existing VoIP technology cannot adjust the quality of voice calls in real time, so that high-quality call services cannot be guaranteed for users, thereby reducing the user experience

Abstract

The invention discloses a method and system for realizing VoIP conversation, comprising that a soft switch server receives a call request from a calling VoIP client, and determines that any one of the calling VoIP client and the called VoIP client is protected by a NAT firewall; The switching server takes the higher level information of the calling VoIP client and the called VoIP client as the call level of this VoIP call; the softswitch server selects the media proxy server corresponding to the call level, and the calling VoIP client and the called party The selected media proxy server is used between VoIP clients to transmit media streams. By distinguishing users through the method of the invention, voice services with differentiated call quality are realized for different users. Furthermore, after the user call is established, the voice service quality is dynamically adjusted according to the change of the user network; further, after the user call is established, the voice service quality is dynamically adjusted according to the change of the server load.

Description

technical field [0001] The invention relates to VoIP (Voice over Internet Protocol) technology, in particular to a method and system for realizing VoIP calls. Background technique [0002] With the rapid development of the mobile Internet, a large number of OTT companies are trying to impact the traditional core business of operators and provide VoIP services one after another. VoIP voice media data is usually transmitted using Real-time Transport Protocol (RTP, Real-time Transport Protocol), however, the RTP protocol is difficult to guarantee the quality of voice calls. [0003] In the prior art, the VoIP service is usually realized by using a call and media proxy mechanism, that is, a softswitch server is used to control call signaling, and a media proxy server is used to provide forwarding services of RTP voice media streams. In the prior art, the information of the media proxy service is usually carried in the call signaling. In the existing technology, users cannot be...
