Research on the evolution and key technology of the next generation new calling network media node

Based on 5G and IP multimedia subsystem (IMS) network architecture, the network architecture of the next generation new calling was put forward by introducing data channel (DC) and artificial intelligence (AI). As the network architecture became more complex, the problems such as many media nodes, circuitous routing, and service delay were particularly prominent. In order to simplify the network and improve efficiency, it is necessary to define the network evolution ideas. Firstly, the future evolution goals of the new call media node was outlined, and then the key technologies in the process of network evolution was conducted in-depth analysis. It provides a reference to the evolution of the new calling media node.
