摘要：
An example apparatus, such as a position server, is caused to receive proximity information from a number of mobile apparatuses located remote from the apparatus, and receive observed current locations from at least some but not all of the mobile apparatuses. The apparatus is also caused to determine a proximity relation between certain ones of the number of mobile apparatuses, where the proximity is reflected by the proximity information received from the mobile apparatuses. And the apparatus is caused to calculate an estimate of a current location of at least one of the one or more remaining mobile apparatuses as a function of the proximity relation between certain ones of the number of mobile apparatuses, and as a function of the observed current locations of the one or more mobile apparatuses.
