Abstract: A system (1, 21) for obtaining samples for a dynamic resource management system in a wireless network is configured to analyze (101) data for a dynamic resource management system to determine one or more combinations of input values which are not present or underrepresented in the data. The dynamic resource management system uses supervised learning to estimate resource demand. The system is further configured to adjust (103) one or more flow characteristics of a data flow between a user device and a base station to obtain one of the combinations of input values, determine a quantity of resources used for the data flow and actual state and/or cell characteristics relevant to the data flow, create a new sample based on the used quantity of resources, the adjusted flow characteristics, and the actual state and/or cell characteristics, and store the new sample in the data.
