Abstract

The invention comprises methods and arrangements for Policy Decision Point discovery in a roaming or handover scenario in an IP network (IN) comprising a plurality of network elements. The authentication function, e.g. an AAA-server, receives the address (ASPDP1) of the serving Policy Decision Point (SPDP1) associated to the user equipment, and stores the address of the serving policy decision point together with the local address of the user equipment. The authentication function sends the address of the serving policy Decision Point to the Home Agent so that the Home Agent can forward the address of the serving policy decision point to the anchor Policy Decision Point and so that the anchor Policy Decision Point can contact the serving policy decision point by using said address of the serving Policy Decision Point.
