Abstract
Location information about a communicating entity (), in particular a mobile entity, is derived by identifying intermediate nodes () along the communication path being used by the entity, and then looking up, in a database (), the geographic significance of at least one of these nodes when considered in a direction along the communication path towards the entity of interest. Preferably, account is taken of any identified downstream/upstream nodes to refine the geographic significance of a node. The geographic significance information can be compiled by taking location fixes at a plurality of endpoint locations and associating the location data thus obtained with the intermediate nodes traversed when communication is effected from the corresponding endpoint locations.
