1. An apparatus, comprising:
- at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to;
perform a set of Earth'"'"'s magnetic field, EMF, measurements inside a building, wherein each EMF measurement result represents at least one of a magnitude and a direction of the EMF in the building;
store the set of EMF measurement results off-line into a memory buffer coupled to the apparatus; and
upon detecting a predefined triggering condition, cause a transfer of the stored set of EMF measurement results to a database entity.

16. A database entity, comprising:
-
at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the database entity, at least to; store an indoor Earth'"'"'s magnetic field, EMF, data representing at least one of magnitude and direction of the EMF in a building; cause a reception of a set of stored EMF measurement results from a mobile apparatus, wherein each EMF measurement result of the set represents at least one of the magnitude and the direction of the EMF in the building and is determined and stored by the mobile apparatus moving in the building; compare the received set of EMF measurement results to the stored EMF data; and determine, on the basis of the comparison, information about movements of the person associated with the mobile apparatus. - View Dependent Claims (17, 18, 19, 20)
