US 2026/0237259 A1 · WAKEUP-SIGNAL FORWARDING METHOD FOR ACCESS ENFORCEMENT POINT(S) AND ACCESS CONTROL SYSTEMS

Abstract

According to a first aspect of the present invention, a computer-implemented wakeup-signal forwarding method for access control is provided, which may be performed by at least a first access enforcement point. The first access enforcement point may be operable in a low-power mode. The first access enforcement point may be operable in in an active mode. The first access enforcement point may be configured to cause operation of a first access point. The first access enforcement point being in the low-power mode may be configured to operate at a lower power consumption as compared to a power consumption of the first access enforcement point being in the active mode. The first access enforcement point may comprise a wakeup receiver configured to receive a wakeup signal. The first access enforcement point may comprise a wakeup transmitter configured to send a wakeup signal. The first access enforcement point may comprise an instruction receiver configured to receive an instruction signal. In the low-power mode of the first access enforcement point, the instruction receiver may be inactive. In the active mode of the first access enforcement point, the instruction receiver may be active. The method may comprise receiving by the wakeup receiver of the first access enforcement point being in the low-power mode, a first wakeup signal. The method may comprise determining whether the first wakeup signal is designated to cause switching of the first access enforcement point into the active mode. The method may comprise, if the first wakeup signal is determined to not being designated to cause switching of the first access enforcement point into the active mode, sending, using the wakeup transmitter, a second wakeup signal. The second wakeup signal may preferably correspond to the first wakeup signal.
