Reconfiguration of a radio positioning support system

Abstract

A method, apparatus and computer readable storage medium are provided for reconfiguring a radio positioning support system. In a method, one or more observation reports are received. Each observation report is associated with a respective radio positioning support device of a radio positioning support system. Each observation report contains an indication for a number of radio positioning support devices and/or for each radio positioning support device from which a radio positioning support signal is observable at a position of said respective radio positioning support device. The method also determines, based on said observation reports, whether a predetermined radio positioning support criterion is met by said radio positioning support system. If it is determined that the predetermined radio positioning support criterion is not met by the radio positioning support system, the method at least partially reconfigures and/or causes at least partially reconfiguration of the radio positioning support system.
