ISWNINTEGRATED SMALL CELL/WI-FI NETWORKS CHARGING IN THE INTEGRATED SMALL CELL/WI-FI NETWORKS ISWN

摘要

The Policy and Charging Enforcement Function (PCEF) can recognize whether the UE accesses through a gateway via a cellular or WIFI connection. Management messages can be modified to leave the PCEF volume-based online billing functionality in the core network (i.e., P-GW / PCEF). Session management messaging between the ISWN (ISW-GW) and the core network (P-GW / PCEF) can be modified so that the core network can be informed when the ISWN moves bearer or flow from one RAT to another. Alternatively, PCEF volume-based online billing functionality can be added to the ISWN. The PCEF of the ISWN may be assigned a task to perform volume based online charging while the UE is in the ISWN.
