BCE has been granted a patent for a system that automatically identifies telephone numbers associated with robocalls or scam calls and blocks them from making calls on the telephone network. The system uses trained models to identify anomalous call behavior and undesirable call types, and then blocks the corresponding phone numbers.

Blocking phone numbers associated with robocalls or scam calls
A recently granted patent (Publication Number: US11758040B2) describes a system and method for blocking phone numbers in a telephone network. The system includes one or more processors and at least one memory for storing instructions. These instructions, when executed by the processors, configure the system to perform various tasks.
The system receives raw call log records from multiple telephone network elements and generates processed call records by formatting the raw call log records into a common format. It also identifies raw call log records or call records associated with the same call and aggregates them together. The processed call records are then periodically processed using trained models to identify phone numbers associated with anomalous call behavior and phone numbers associated with a specific type of undesirable call behavior, such as Wangiri type scam calls.
Once identified, the system blocks the phone numbers of the anomalous and undesirable call types from making calls over the telephone network. Additionally, the system can automatically call these phone numbers and record a portion of the calls made. It generates a user interface that includes an indication of the identified phone numbers and provides this interface to an investigator of the telephone network operator. The investigator can then select the phone numbers to be blocked based on the provided information.
The system can also retrieve additional information on the identified phone numbers from various sources and include this information in the generated user interface. Furthermore, the system allows for the unblocking of previously blocked phone numbers. It identifies blocked phone numbers and determines if there has been no call activity associated with these numbers for a threshold period of days. If there has been no activity, the system unblocks the phone numbers.
In summary, the granted patent describes a system and method for blocking phone numbers in a telephone network based on anomalous and undesirable call behavior. It includes features such as automatic calling and recording, user interface generation for investigators, retrieval of additional information, and unblocking of previously blocked phone numbers. This system aims to enhance the security and efficiency of telephone networks by preventing fraudulent and undesirable calls.
