System and methods for dynamic breakout-path determination in telecommunications networks

A method for optimizing break-out/break-in paths of voice calls between a source operator's (SO) IP Multimedia Core Network Subsystems (IMS) and a target operator's network (TO IMS), the method comprising:

• obtaining a voice call originating from a user equipment (UE) in the SO IMS and terminating at an UE in the TO IMS;
• determining a routing policy for the voice call;
• determining an optimal TO Interconnect Session Border Controller (ISBC) by applying at least one path metric according to the routing policy to a machine learning (ML) model for determining an optimal route between the SO IMS and the TO IMS;
• providing, to the ML model, feedback on the voice call routed to the optimal TO ISBC;
• routing the voice call to the optimal TO ISBC,
• wherein, the ML model, for determining the optimal TO ISBC using, for each of the at least one path metric, one or more routing parameter rankings of a plurality of possible paths between the SO IMS and the TO IMS, and
• wherein the ML model is configured to update the one or more routing parameter rankings of the plurality of possible paths between the SO IMS and the TO IMS based on the feedback.

A non-transitory computer-readable recording medium having recorded thereon instructions executable by at least one processor configured to perform a method for optimizing break-out/break-in paths of voice calls between a source operator's (SO) IP Multimedia Core Network Subsystems (IMS) and a target operator's network (TO IMS), the method comprising:

• obtaining a voice call originating from a user equipment (UE) in the SO IMS and terminating at an UE in the TO IMS;
• determining a routing policy for the voice call;
• determining an optimal TO Interconnect Session Border Controller (ISBC) by applying at least one path metric according to the routing policy to a machine learning (ML) model for determining an optimal route between the SO IMS and the TO IMS;
• providing, to the ML model, feedback on the voice call routed to the optimal TO ISBC
• routing the voice call to the optimal TO ISBC,
• wherein, the ML model, for determining the optimal TO ISBC using, for each of the at least one path metric, one or more routing parameter rankings of a plurality of possible paths between the SO IMS and the TO IMS, and
• wherein the ML model is configured to update the one or more routing parameter rankings of the plurality of possible paths between the SO IMS and the TO IMS based on the feedback.
