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.

主权项

1. A method for operating a subscription control node in a communications network, the communications network including multiple user equipments, UEs, and multiple network address translation 64, NAT64, nodes, the subscription control node including subscription information for one or more of the UEs, the subscription information for each UE including translation state usage information associated with one or more of the NAT64 nodes servicing that UE, the method comprising:
collecting translation state usage information from each of the NAT64 nodes; identifying 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; adjusting the translation state usage information in the subscription information of the identified set of UE(s) to meet the maximum translation state usage for each UE, and updating the corresponding subscription information; and transmitting the updated subscription information of the identified set of UE(s) to the corresponding NAT64 nodes.
