Identity resolution of a user equipment (ue) connectable to a fifth generation (5g) mobile network during capture by a cell-site simulator (css)

A system associated with a Cell-Site Simulator (CSS) within a geographical location covered by a Fifth Generation (5G) mobile network, comprising:

• at least one memory comprising a pseudo-Authentication Server Function (AUSF) component as a component of an architecture of a core mobile network of the 5G mobile network, an existing AUSF module distinct from the pseudo-AUSF component as an existing core functionality of the core mobile network, and an existing Unified Data Management (UDM) module of the core mobile network, the pseudo-AUSF component implemented with a narrow subset of functionalities associated with the existing AUSF module;
• and
• at least one processor communicatively coupled to the at least one memory, the at least one processor executing instructions to:
• in accordance with an authorized data processing device self-identifying to the CSS with a concealed identifier of a User Equipment (UE) connectable to the 5G mobile network, utilize the pseudo-AUSF component instead of the existing AUSF module to communicate with the existing UDM module of the core mobile network, and
• in accordance with the communication between the pseudo-AUSF component and the existing UDM module, de-conceal the concealed identifier to generate a permanent identifier of the UE accessible to the authorized data processing device.
