Abstract
A method and apparatus for performing a caller investigation in order to provide relation information to a called party () regarding an unknown calling party (), when implemented in a service entity () serving said called party. A relation query for the calling party is received from the called party, and it is then determined whether the calling party is known and related to any third party directly or indirectly known to the called party by checking a contact list (-) defined for said third party. The reliability of the calling party can then be better assessed based on how the calling party is related to the called party, if related at all. The called party may use this information for deciding how to respond to a communication request from said calling party.
