GTP-C Load Control

This feature enables cnSGWc and PGW-C to gather and send Load Control Information (LCI) to GTP-C peers (for example, MME via cnSGWc, and ePDG). In broad terms, GTP-C load control denotes a preventive action and GTP-C overload control indicates a corrective action.

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

  • Load control allows better balancing of the session load; this mechanism prevents the GTP-C overload scenario.

  • LCI helps to balance the session load adaptively across entities supporting the same function according to their effective load.

  • Load control does not trigger overload mitigation actions even if the GTP-C entity reports a high load.
