Presented herein are techniques to facilitate resiliency, overload control, and/or the like for an Access and Mobility Management Function (AMF) in a Third Generation Partnership Project (3GPP) mobile network architecture. In one instance, a method is provided that includes initiating, by a buddy AMF, a heartbeat exchange with a primary AMF. The method may further include identifying a status condition for the primary AMF by the buddy AMF based on the heartbeat exchange and providing a status indication to a radio access network node by the buddy AMF based on the status condition for the primary AMF.
