    Abstract: In some implementations, radio access technology (RAT) signals can be monitored and used to synchronize an internal clock of a mobile device to a network system clock without registering the mobile device to the network. In some implementations, a RAT processor can be configured to receive RAT signals and to prevent transmission of RAT signals. In some implementations, the internal clock can be associated with a GNSS processor and can be used to calculate a location of the mobile device. In some implementations, a RAT processor that is configured for a particular radio access technology can be configured to monitor signals associated with another radio access technology when synchronizing the internal clock. In some implementations, the RAT processor can monitor signals in response to a power event. The power event can be associated with powering a display of the mobile device.

    Abstract: Data provided by an access point of a wireless local area network (“WLAN”) is used to assist a mobile device in cell reselection. If a serving cell of a cellular communications network is unsuitable for providing cellular service, a candidate cell co-located with the serving cell can be selected as the serving cell based on quality of service metrics associated with the serving cell and the candidate cell. The mobile device can be proactively commanded to switch to the candidate cell for receiving cellular service. In some implementations, the quality of service metrics are calculated from call logs collected from mobile devices operating in the cellular communications network. In some implementations, network information regarding serving cell performance can be used with the call logs to generate the quality of service metrics.

    Abstract: Methods and apparatus for managing radio measurements during discontinuous reception. In one exemplary embodiment, the distribution of Long Term Evolution (LTE) DRX measurements is staggered or distributed across multiple DRX cycles (which may be contiguous or non-contiguous) so as to reduce the transceiver activity and power consumption. The exemplary UE in one implementation only performs a subset of measurements during each DRX cycle. By staggering or distributing cell measurements over multiple DRX cycles, the UE can improve power consumption, while still conforming to measurement requirements.
