1. An apparatus for implementing a network function (NF) service consumer, comprising:
at least one processor; and
at least one memory comprising computer program code, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to perform at least:
after an overload condition for the network function service consumer is determined, transmitting, to a network function (NF) service producer, a 3GPP-service based interface (SBI) overload control information (OCI) header, the 3GPP-SBI OCI header comprising overload control information to be used by a network function (NF) service producer for throttling notifications,
wherein the overload control information comprises a scope that is set to one of: at least one callback uniform resource identifier (URI); a network function (NF) service instance; network function (NF) service set; network function (NF) instance; network function (NF) set, or a service name; of a service;
wherein, when the scope is set to the at least one callback uniform resource identifier (URI), the overload control information (OCI) is configured to apply to all notification requests or callback requests with a callback uniform resource identifier (URI) matching the at least one callback uniform resource identifier (URI) that is set in the scope, and
wherein, when the scope is set to one of the network function (NF) service instance, the network function (NF) service set, the network function (NF) instance, the network function (NF) set, or a service name of the service, the overload control information (OCI) is configured to apply to notification requests or callback requests with a matching binding indication.
