Latest Patents

One of his latest patents is titled "Non-validated emergency calls for all-IP 3GPP IMS networks." This invention allows emergency calls to be completed in an all Internet Protocol (IP) network without a valid SIM card. The system substitutes a valid Subscriber Identity Module for the missing or invalid SIM only when an emergency call is attempted. The emergency call can be sent via an IMSI from an embedded SIM or modified with an IMSI substituted by an Emergency SIM Pool Function before being sent to the HLR for validation. This innovation ensures that the emergency call is completed, as the user equipment (UE) is considered validated by the network.

Another significant patent is "Methods for handoff of an active communication connection from a macrocell to a femtocell." This method improves the handoff process for mobile user stations transitioning from a macrocell to femtocells, particularly in indoor environments where signal strength may be low. The invention efficiently performs the handoff while minimizing the risk of dropping the active communication connection.
