POLICY AND CHARGING CONTROL (PCC) FOR NAT64 AND DNS64

摘要

A mechanism for use by a subscription control node, one or more NAT64 nodes and/or DNS64 nodes to interact in a communications network with multiple user equipments (UEs) to control the UE usage of the NAT64 and/or DNS64 communications resources. The subscription control node includes subscription information for one or more of the UE(s), the subscription information for each UE including translation state usage information associated with one or more of the NAT64 nodes servicing the UE. The subscription control node collects translation state usage information from each NAT64 node, and identifies a set of one or more UE(s) exceeding a maximum translation state usage allocated to each of the multiple UEs based on the corresponding subscription information and the collected translation state usage information. The subscription information for the identified UEs is adjusted so the identified set of UE(s) meet the maximum translation state usage for each UE.
