Abstract:

Disclosed herein are systems and methods for facilitating wireless communication of a wearable device. In one aspect, a wireless device receives a paging message from a cellular network, via a wireless link between the wireless device and a companion device. The paging message can be received while a cellular modem of the wireless device is operating in reduced power mode and not registered with the cellular network, and the companion device is registered with the cellular network. The wireless device can transition the cellular modem from the reduced power mode to an active mode in response to receiving the paging message via the wireless link with the companion device. The wireless device can register with the cellular network after the modem has transitioned to active mode, to establish a cellular link directly with the cellular network.
