A mobile entity (20) provides accuracy limit data (Q) that indicates a desired accuracy of location data (L) about the mobile entity. This data (Q) is passed, either directly or indirectly from the mobile entity (20), to a location handling system (80) which provides location data (L) about the corresponding mobile entity limited to the desired accuracy. In one embodiment, the location handling system is a location server. In another embodiment the location handling system is a decryption entity (80) for decrypting encrypted location data. <IMAGE> |
