Claim Text:
1. An apparatus comprising: a processor, and a memory, said memory storing a program comprising program code, said program configured to cause said apparatus, when said program is executed on said processor, to perform pre-filtering of information, which information is a report that contains a position of a terminal that is able to hear a communication node, by determining whether said information shall be discarded or made available to a process that comprises generating and/or updating at least one model for a coverage area of said communication node based on a plurality of reports from one or more terminals that report their respective positions and respective lists of one or more communications nodes that can be heard at said respective positions, wherein said determining is based on at least one model for said coverage area of said communication node produced by said process, wherein said determining comprises checking if said position of said terminal is covered by said at least one model on which said determining is based and discarding said information or making said information available to said process at least partially based on an outcome of said checking, and wherein said at least one model on which said determining is based, differs from at least one further model that is produced by said process at least in its format so that said checking if said position is covered by said at least one model on which said determining is based is less complex than a checking if said position is covered by said at least one further model.
