Filtering messages using information about the sender's location

摘要

A mobile device (502) provides its location information to contacts of a user of the mobile device (502). A contact has a particular precision level (532) assigned thereto from a set of two or more dissimilar precision levels. The assignment of precision levels (532) to contacts is according to one or more criteria. The mobile device (502) ensures that any location information of the mobile device (502) provided to the contact is not more precise than the precision level (532) currently assigned to the contact.
