Apple patents phone wake-up signal to request network info on demand

Apple describes a method where a phone sends a specific wake-up signal to a cell tower to request basic network configuration data. This allows the tower to transmit the necessary system information only when the phone asks for it, rather than broadcasting it continuously. The process helps the phone find the network details it needs to connect without constantly listening for updates.

Why it mattersThis technique could help phones save battery by only requesting network data when needed, rather than constantly scanning for it.

In the filing’s own words

A user equipment (UE) configured to decode, based on signals received from a base station, configuration information comprising (i) an indication that the base station is not transmitting System Information Block 1 (SIB1) information and (ii) wakeup signal (WUS) configuration information indicating information for sending a WUS to trigger the base station to transmit SIB1 information, configure transceiver circuitry to transmit the WUS to the base station according to the WUS configuration information and monitor for SIB1 information transmitted from the base station.

What exactly they claim (claim 1)

1. An apparatus of a user equipment (UE), the apparatus comprising processing circuitry configured to: decode, based on signals received from a base station, configuration information comprising (i) an indication that the base station is not transmitting System Information Block 1 (SIB1) information and (ii) wakeup signal (WUS) configuration information indicating information for sending a WUS to trigger the base station to transmit SIB1 information; configure transceiver circuitry to transmit the WUS to the base station according to the WUS configuration information; and monitor for SIB1 information transmitted from the base station.
