Estimating the term…
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 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, SPDPA1) 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.
A method suitable for Policy Decision Point discovery in a roaming or handover scenario in an IP network, the network comprising the following network elements:
A Re-direct Policy Decision Function (RPDF) device suitable for deliver addresses of Policy Decision Points to network elements (SPDPI, APDP, AF, APEP) in an IP network and which network elements comprises at least a mobile terminal and a plurality of Policy Decision Points (SPDPAI, APDPA), and which Redirect Policy Decision Function comprising a memory for storing an address (APDPA, SPDPAI) of a Policy Decision Point and an address of the Mobile Terminal wherein the Re-direct Policy Decision Function (RPDF) comprises:
A System comprising at least one IP network which IP network comprises network elements including a plurality of Policy Enforcement Points, a plurality of Policy Decision Points, at least one application function, at least one Mobile Terminal, a Database comprising policy information related to the Mobile Terminal wherein the system comprises:
