- Traditional services guarantee user experience through QoS guarantees.
- holographic and Extended Reality (XR) services the balance between resource occupation and user experience needs to be considered. That is, for holographic services, the purpose is not to guarantee the QOS of one or several flows required by the application layer, but to ensure user service experience when bandwidth requirements are high and resources are limited, or to improve service capacity when resources are certain (that is, how many holographic services can be served at the same time).
