Methods and apparatus for call traffic anomaly mitigation

A method for call traffic anomaly mitigation, comprising:

• receiving a scoring request including a telephone number associated with a telephone call at a scoring device from a call processing entity;
• receiving a violator list including telephone numbers and their corresponding severity values at the scoring device from an anomaly analyzer device;
• determining a severity value associated with the telephone number by performing a lookup operation in the violator list;
• performing a random simulation, by the scoring device, using the severity value interpreted as a probability, as an input to determine an indicator value;
• the scoring device inputting the indicator value into a model derived from historical data to determine a call reputation score;
• transmitting the call reputation score to the call processing entity;
• comparing the call reputation score to a call reputation score threshold at the call processing entity;
• and
• triggering a call treatment based on the call reputation score at the call processing entity.

A device for call traffic anomaly mitigation, comprising:

• a memory;
• a processor coupled to the memory, wherein the processor is configured to:
• receive a scoring request including call data associated with a telephone call from a call processing entity, wherein the call data includes a telephone number;
• receive a violator list of telephone numbers and their corresponding severity values from an anomaly analyzer device;
• determine a severity value associated with the telephone number by performing a lookup operation in the violator list;
• perform a random simulation using the severity value, interpreted as a probability, as an input to determine an indicator value;
• input the indicator value into a model derived from historical data to determine a call reputation score;
• transmit the call reputation score to the call processing entity for call treatment;
• and
• triggering the call treatment based on the call reputation score at the call processing entity.
