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.

Abstract: A device may include a controller and a modem of a first wireless network. The controller may determine that the modem is in active mode and the device is using a second wireless network for communication instead of the first wireless network. In response to the determining, the controller may switch the modem into power-save mode. In response to a handover triggering event, the controller may switch the modem to the active mode and acquire a service of the first wireless network without registering with the first wireless network. The controller may determine that a communication service is to be handed over to the service of the first wireless network. In response to determining that the communication service is to be handed over, the controller may perform registration with the first wireless network, and perform handover of the communication service to the service of the first wireless network.
