Abstract: A method comprises receiving a first call from a user device operated by an emergency personnel, receiving a personal identification number associated with the emergency personnel from the user device, validating the personal identification number by verifying that the personal identification number is stored at a data store in association with an active account, wherein the active account is associated with the emergency personnel, transmitting a first prompt for voice verification registration to the user device, receiving a response from the user device to perform the voice verification registration in response to the first prompt, and either performing voice verification with the user using the user device or transmitting a prompt for a requested destination to the user device based on the response.

Abstract: A method comprises receiving, by an application executing at an emergency telecommunications service system, from a user device, a Session Initiation Protocol (SIP) invite comprising a first header carrying a device identifier of the user device and an X-header carrying a personal identification number (PIN) of an authorized user operating the user device and a destination number requested by the user device, authenticating, by the application, the PIN as being associated with a valid user account at the emergency telecommunications service system, and completing, by the application, a call from the user device to the destination number.

Abstract: A method comprising obtaining, using an artificial intelligence model, a trust parameter and a confidence score based on the device identifier of a user device and an access history of a user, wherein the trust parameter comprises a predicted value indicating a level of trust associated with the user device, and wherein the confidence score indicates a confidence level of the trust parameter, an authentication parameter indicating a permitted dynamic authentication for the user device based on an authentication rule, wherein the authentication rule comprises one or more conditions based on a comparison of at least one of the trust parameter or confidence score with a preset threshold, determining an authentication parameter indicating a permitted dynamic authentication for the user device based on an authentication rule, and transmitting an authentication prompt to the user device to provide the abbreviated verification credential to authenticate with the emergency telecommunications service system.

Abstract: Systems and methods are provided for mitigating undesirable service disruptions in a communications network. Based on a determination that an access failure rate exceeds a threshold, it may be determined that a particular service is degraded or that a requesting user device is not authorized to access the service. One or more mitigation protocols may be used to block subsequent attempts by the requesting user device, a set of user devices associated with the requesting user device, or an area associated with the requesting user device to request access to the service.

Abstract: Systems and method are provided for mitigating hacking of restricted access telecommunication services. In response to an authentication response from a user device, an authentication failure type and authentication failure frequency may be determined. Based on the authentication failure type and authentication failure frequency, the user device is blocked from accessing the telecommunication service for a predetermined period of time, preventing the service from being congested by recurring unauthorized users.
