GTP-C Overload Control

This feature enables cnSGWc and PGW-C to gather and send Overload Control Information (OCI) to GTP-C peers (for example, MME via cnSGWc, and ePDG). A GTP-C entity is in overload when it operates over its signaling capacity, which results in diminished performance.

The advantages of enabling GTP-C Overload Control are as follows:

  • Avoids overloading of GTP-C entity

  • Improves load distribution on SMF and cnSGWc which in turn reduces the occurrence of SMF overload.

  • Aims at shedding the incoming traffic as much as possible when an overload has occurred
