Apple patents method to sync power-saving cycles across multiple networks

Patent drawing
Patent drawing from the official filing.

Apple describes a way for a device to manage its battery-saving sleep cycles when connected to two different wireless networks at once. The device sends information to the networks to adjust the timing of its active listening periods, ensuring the 'on' times do not overlap.

Why it mattersThis technical adjustment helps reduce battery drain for devices that maintain connections to multiple cellular networks simultaneously.

In the filing’s own words

A user equipment (UE) includes at least one wireless transceiver and a processor. The processor is configured to determine to operate in a first C-DRX mode with a first network and to operate in a second C-DRX mode with a second network. The processor is also configured to transmit, to a first base station of the first network, via a wireless transceiver of the at least one wireless transceiver, UE assistance information that includes 1) a requested C-DRX offset for the first C-DRX mode, or 2) a C-DRX configuration of the first C-DRX mode.

What exactly they claim (claim 1)

1. An apparatus comprising memory coupled to a processor, the processor configured to: determine to operate in a first C-DRX mode with a first network and to operate in a second C-DRX mode with a second network; and generate, for transmission, UE assistance information that includes a requested C-DRX offset for the first C-DRX mode, the requested C-DRX offset to stagger a first C-DRX ON time of the first C-DRX mode with respect to a second C-DRX ON time of the second C-DRX mode.
