Abstract: A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block. The mapping information is communicated, processed, and stored once for the complete block, instead of for every new data connection. This process reduces processing, communication, and storage requirements.

Abstract: Disclosed herein are systems, methods, and computer-readable media for applying differential charging over user plane for DCNR capable UEs. In one aspect, a method includes receiving a session request at a control plane gateway in association with a dual connectivity attachment request by a user equipment to connect to a network, sending a request for tunnel binding IDs to a Policy and Charging Rules Function (PCRF), wherein each of the tunnel binding IDs is associated with one of different types of network access for the user equipment, receiving the tunnel binding IDs from the PCRF, and programming a user plane with the tunnel binding IDs and corresponding charging rules for the different types of network access, the user equipment being charged for data usage using the charging rules and depending on which of the different types of network access is used by the user equipment to connect to the network.
