Mitigating leakage for telecommunications service providers

A system for mitigating leakage for a telecommunications service provider, the system comprising:

• at least one hardware processor;
• and
• at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
• receive, from an online charging system (OCS), real-time call detail records (CDRs) for multiple wireless devices subscribed to the telecommunications service provider,
• wherein the real-time CDRs comprise information regarding telecommunication sessions of the multiple wireless devices,
• wherein a number of the real-time CDRs per a time segment correspond to a number of telecommunication sessions by the multiple wireless devices by the time segment, and
• wherein the real-time CDRs associated with the one or more of the telecommunications sessions comprise an indication of an attribution for each telecommunications session;
• associate each of the CDRs with a respective cluster of multiple clusters using a network service product type associated with each of the CDRs;
• create aggregated sub-clusters of CDRs,
• wherein each aggregated sub-cluster of CDRs includes a portion of the CDRs associated with a respective cluster, and
• wherein each aggregated sub-cluster of CDRs is created based on the attribution for each telecommunications session;
• input the aggregated sub-clusters of CDRs and the number of CDRs per the time segment to an artificial intelligent (AI) model to evaluate whether the aggregated sub-clusters of CDRs are associated with a leakage;
• responsive to an evaluation that a particular aggregated sub-cluster of CDRs is associated with the leakage, perform an action to mitigate the leakage.

A non-transitory, computer-readable storage medium comprising instructions recorded thereon, wherein the instructions, when executed by at least one data processor of a system, cause the system to:

• receive, from an online charging system (OCS), real-time call detail records (CDRs) for multiple wireless devices,
• wherein the real-time CDRs comprise information regarding telecommunication sessions of the multiple wireless devices subscribed to a telecommunications service provider,
• wherein a number of the real-time CDRs per a time segment correspond to a number of telecommunication sessions by the multiple wireless devices by the time segment, and
• wherein the real-time CDRs associated with the one or more of the telecommunications sessions comprise an indication of an attribution for each telecommunications session;
• associate each of the CDRs with a respective cluster of multiple clusters using a network service product type associated with each of the CDRs;
• create aggregated sub-clusters of CDRs,
• wherein each aggregated sub-cluster of CDRs includes a portion of the CDRs associated with a respective cluster, and
• wherein each aggregated sub-cluster of CDRs is created based on the attribution for each telecommunications session;
• input the aggregated sub-clusters of CDRs and the number of CDRs per the time segment to an artificial intelligent (AI) model to evaluate whether the aggregated sub-clusters of CDRs are associated with a leakage;
• responsive to an evaluation that a particular aggregated sub-cluster of CDRs is associated with the leakage, perform an action to mitigate the leakage.
