Network cell classification for qos policy optimization

Abstract

Wireless network cells are classified into groups based on radio and network conditions in the cells. Quality of Service, QoS, policy optimization is then performed per each classified cell group, by selecting more or less stringent predetermined rules until a target Quality of Experience, QoE, is met, at least for the highest priority traffic. To classify the cells into groups, the radio and network parameters collected () are ranked () by their influence on QoE. Based on this ranking, only a few of the most impactful parameter are selected (). The range of values of each parameter is then divided () into a plurality of ranges, for example by the ability of the parameter, when within each range, to impact service quality. Cells are then classified () into groups based on the same parameters within the cells falling into the same value ranges. QoE targets for at least high priority traffic classes are obtained (). QoS policy is then optimized (), separately for each classified cell group, to meet the QoE targets. The optimized QoS policy is applied () to a new UE entering a cell.
