Abstract: In order to improve the management of the power consumption of electronic devices (such as cellular telephones), the operating mode of an interface circuit in an electronic device may be changed when certain commands are received. In particular, when one or more commands are received that disable data communication via the interface circuit and a cellular-telephone network and/or enable communication via another interface circuit in the electronic device and a wireless local area network (WLAN), the interface circuit may be transitioned to an operating mode in which data communication via the cellular-telephone network using a communication protocol that supports only data and no voice is disabled. For example, the communication protocol may include a Long Term Evolution (LTE)-compatible communication protocol.

Abstract: A method for network reselection by a wireless communication device is provided. The wireless communication device can have an established connection to a first network. The method can include measuring a signal strength and a signal-to-noise ratio of the first network. The method can further include determining that the signal strength satisfies a signal strength threshold. The method can additionally include comparing the signal-to-noise ratio to a signal-to-noise ratio threshold. The method can also include disconnecting from the first network and reselecting to a second network in an instance in which the signal-to-noise ratio does not satisfy the signal-to-noise ratio threshold even though the signal strength satisfies the signal strength threshold.

Abstract: Methods and apparatus for reducing voice call drop rate. Existing devices do not account for the added burden of background services on voice calls. Specifically, multi-RAB scenarios (e.g., a voice call and background services) can experience significant reduction in call quality. Accordingly, in one exemplary embodiment, background services that are not time-critical and/or application-critical can be suspended while a voice call is in progress. By suspending background traffic during a call, the device can avoid unnecessary multi-RAB voice call operation, which significantly improves overall network operation and user experience.
