METHOD AND ARRANGEMENT FOR HIGH PRECISION POSITION REFERENCE MEASUREMENTS AT INDOOR LOCATIONS

摘要

The present invention addresses generating of feasible high precision indoor positioning measurements. A positioning server sets up an interface to which ordinary users may connect with their cellular phones. Using this interface the user can select one out of a plurality of indoor locations where the cellular operator wishes to have high precision position reference measurements performed. The user moves to said indoor location and initiates at this location, by interaction with said interface, the reference measurement. By logging an identity of the user or the time of the positioning the selected indoor location can be correlated to a determined tag in the RAN. The tag together with the indoor location that has been selected by help of the interface towards the positioning server constitutes one tagged high precision position measurement.
