In this work, we make three main contributions.
First, we propose a dual-storage architecture that cleanly separates policy definitions from UE bindings. By doing so, we eliminate the massive redundancy caused by storing the same policies repeatedly for millions of UEs.
Second, we introduce an intelligent caching mechanism that allows us to reduce storage requirements by around 50 to 60 percent, while adding only sub-millisecond latency overhead.
Finally, our design is implemented as a drop-in replacement for the PCF. It remains fully compliant with the standard 3GPP N15 and N36 interfaces, which means it can be deployed seamlessly in existing 5G Core networks. |
