Methods for intelligent signaling message steering in 5G core

A network traffic management device, comprising memory comprising programmed instructions stored thereon and one or more processors configured to be capable of executing the stored programmed instructions to:

• receive a network request;
• identify, based on the network request, a set of features;
• identify, from a plurality of producer network functions (NFs) and based on the set of features and a failure probability table, a faulty one of the producer NFs by determining that a failure probability rate associated with at least one feature in the set of features exceeds a predetermined threshold;
• define a subset of the plurality of producer NFs, wherein the subset of the plurality of producer NFs excludes the faulty one of the producer NFs;
• and
• route the network request to one of the subset of the plurality of producer NFs.

A non-transitory computer readable medium having stored thereon instructions comprising executable code that, when executed by one or more processors, causes the processors to:

• receive a network request;
• identify, based on the network request, a set of features;
• identify, from a plurality of producer network functions (NFs) and based on the set of features and a failure probability table, a faulty one of the producer NFs by determining that a failure probability rate associated with at least one feature in the set of features exceeds a predetermined threshold;
• define a subset of the plurality of producer NFs, wherein the subset of the plurality of producer NFs excludes the faulty one of the producer NFs;
• and
• route the network request to one of the subset of the plurality of producer NFs.
