Abstract: An example method of operation may include one or more of identifying an outbound call placed by a mobile device subscribed to a protected carrier network, determining the outbound call is destined for a destination telephone number that was stored in a call history of the mobile device, determining the destination telephone number is a scam call suspect telephone number based on one or more identified call filter parameters associated with the destination telephone number, and forwarding a scam call notification to the mobile device while the outbound call is dialing the destination telephone number.

Abstract: An example method of operation may include one or more of identifying an outbound call placed by a mobile device subscribed to a protected carrier network, determining the outbound call is destined for a destination telephone number that was stored in a call history of the mobile device, determining the destination telephone number is a scam call suspect telephone number based on one or more identified call filter parameters associated with the destination telephone number, and forwarding a scam call notification to the mobile device while the outbound call is dialing the destination telephone number.

Abstract: One example method of operation may include collecting call metric data over a predefined period of time for identified calls, querying the call metric data to identify whether one or more call filtering criteria parameters require changes, determining one or more call filtering criteria parameters require changes based on a deviation from one or more expected call metric data values included in the call metric data, modifying one or more of the call filtering criteria parameters, and updating an active call scam model stored on a call processing server based on the one or more call filtering parameters.

Abstract: An example method of operation may include one or more of identifying an inbound call intended for a mobile device subscribed to a protected carrier network, determining the inbound call is assigned an origination telephone number that is subscribed to the protected carrier network, determining whether an inbound call origination source location indicates the protected carrier network or an out-of-network carrier network based on one or more call parameters received with the inbound call, and determining whether to transmit an indication to the mobile device that the inbound call has an elevated likelihood of being a scam call based on the inbound call origination source location.

Abstract: One example method of operation may include identifying a call from a caller and destined for a callee, receiving a data message associated with the call, forwarding the data message to a call processing server, processing the data message to identify one or more call parameters, comparing the one or more call parameters to an active call scam model applied by the call processing server, determining a scam score for the call based on the comparing of the one or more call parameters to the active call scam model applied by the call processing server, and determining whether to notify the callee that the call is a scam based on the scam score.

Abstract: An example method of operation may include one or more of identifying an inbound call intended for a mobile device subscribed to a protected carrier network, determining the inbound call is assigned an origination telephone number that is subscribed to the protected carrier network, determining whether an inbound call origination source location indicates the protected carrier network or an out-of-network carrier network based on one or more call parameters received with the inbound call, and determining whether to transmit an indication to the mobile device that the inbound call has an elevated likelihood of being a scam call based on the inbound call origination source location.

Abstract: One example method of operation may include receiving a call message intended for a call recipient, removing one or more portions of call message data included in the call message, identifying one or more of a trunk group and an entry point associated with the received call message, adding one or more of a trunk group identifier (TGRP) and a universally unique identifier (UUID) to the call message to create a modified call message, and forwarding the modified call message to a destination network associated with the call recipient.

Abstract: One example method of operation may include identifying call data associated with a received call, identifying call parameters from the call data, and the call parameters include one or more call routing parameters associated with call routing of the call and one or more call session parameters associated with a call session of the call, assigning weights to one or more of the call routing parameters and the call session parameters, determining a scam score for the call based on a sum of the weights applied to the call routing parameters and the call session parameters, and blocking the call when the scam score is greater than or equal to a predetermined threshold scam score.

Abstract: One example method of operation may include receiving one or more data messages, identifying calls and corresponding call data from the one or more messages, identifying call parameters from the call data, applying a call activity filter criteria to the call parameters to identify a suspect sub-set of the call parameters which indicate an elevated likelihood of call scam, forwarding the call parameters and the suspect sub-set of call parameters to one or more call data tables, and assigning one or more scam designation threshold scores to the suspect sub-set of the call parameters in the one or more call data tables.

Abstract: An example method of operation may include one or more of identifying an inbound call intended for a mobile device subscribed to a protected carrier network, determining the inbound call is assigned an origination telephone number that is subscribed to the protected carrier network, determining whether an inbound call origination source location indicates the protected carrier network or an out-of-network carrier network based on one or more call parameters received with the inbound call, and determining whether to transmit an indication to the mobile device that the inbound call has an elevated likelihood of being a scam call based on the inbound call origination source location.
