The invention introduces a Re-direct Policy Decision (RPDF) Function which can deliver addresses to PDPs associated to a certain Mobile Terminal. The RPDF comprises a memory for storing addresses (APDPA, SPDPA) of Policy Decision Points and Mobile Terminals. The RPDF makes it possible for a network element, e.g. an application function, a policy enforcement point or another policy decision point, to find a Policy Decision Point associated to the Mobile Terminal.
