A system, method, node, virtualized network function, and computer program for preserving a media stream quality at processing of a media stream by a virtualized network function for media handling () is presented. The virtualized network function for media handling () is running in a network function virtualization infrastructure () hosting the virtualized network function for media handling (). The virtualized network function for media handling () is managed by a virtualized network function manager (). The method comprises to determine a media stream quality caused by the processing of the media stream by the virtualized network function for media handling (). The method further comprises that the virtualized network function manager () scales the virtualized network function for media handling () as a result of the determining step.

Method for preserving media plane quality

Systems and methods for dynamically causing a terminal to change audio codec modes during a session with another terminal. In one aspect, the terminal is forced use to switch to a more resilient audio codec mode when the quality of wireless channel being used by the terminal deteriorates below a threshold.
