Exploratory Analysis of a GGSN’s PDP Context Signaling Load

الملخص EN

This paper takes an exploratory look on control plane signaling in a mobile cellular core network.

In contrast to most contributions in this field, our focus does not lie on the wireless or user-oriented parts of the network, but on signaling in the core network.

In an investigation of core network data we take a look at statistics related to GTP tunnels and their signaling.

Based on the results thereof we propose a definition of load at the GGSN and create an initial load queuing model.

We find signs of user devices putting burden on the core network through their behavior.
