Apple Receives Patent for Solution to Allow Off-Network Lawful Intercept Using ProSe
Friday, July 22, 2022 | Comments

Apple received a patent for a solution intended to help law enforcement perform a “lawful intercept” operation when a target mode may be off network.

According to the patent, which was issued by the U.S. Patent and Trademark Office (USPTO) July 19, the technique is based off of the Third Generation Partnership Project’s (3GPP) proximity services (ProSe), which is intended to provide direct mode communications between devices.

Under lawful intercept, carriers can allow law enforcement agencies to intercept specific traffic for identified mobile devices.

“In ProSe communications, a relay device, such as a mobile device acting as a relay device, may be used to couple another mobile device, such as one that is out of the coverage area of the cellular network, to the cellular network,” the patent said. “Implementing lawful intercept in this situation can be problematic, however, as the mobile device that is to be targeted for lawful intercept may not be visible to the cellular network.”

The Apple solution is intended to help address that deficiency. Find the full patent here.
