Feature Description
Important | The PGW-C term used in this chapter denote the EPS interworking functionality supported by SMF and must not be assumed as a standalone P-GW that is used in the LTE network. |
The SMF provides mechanisms to manage the overload and congestion that occur on the SMF and Service-based Architecture (SBA). The SMF receives ingress messages at a rate higher than the engineered capacity. The internal queues on the SMF may experience higher utilization level than the configured level. This scenario may occur on the SBA servers, directly or indirectly, due to overloaded traffic from the network or from the SMF.
