A FIRST NETWORK ENTITY, A SECOND NETWORK ENTITIY, AND A THIRD NETWORK ENTITIY FOR OBTAINING AN AVERAGE ACTIVE TIME PERIOD FOR A QOS LEVEL

摘要

The invention relates to obtaining an average active time period for a quality of service (QoS) level, wherein the average active time period indicates the length of time a QoS flow can be expected to be kept alive at the QoS level. A first network entity (100) requests and receives from second network entity (300) at least one of: a set of active time periods for a QoS level and an average active time period for the QoS level, wherein an active time period is a time period during which a QoS flow is active at the QoS level. Based on the information received from second network entity (300), the first network entity (100) derive an average active time period for the QoS level.
