Abstract: Described herein are apparatus, systems and methods for opportunistic system selection and reselection to avoid jammer desense intermodulation distortion. A method may comprise, at a user equipment (“UE”), identifying a list of frequencies and bands available to a cellular modem of the UE for one of system selection and system reselection, identifying a subset of the list of frequencies and bands based on an operation of a non-cellular wireless communication component of the UE, storing the subset of the list of frequencies and bands in a graylist, and performing, by the cellular modem, a search for one of the system selection and the system reselection based on the graylist.

Abstract: Methods and apparatus for reducing voice call drop rate are disclosed. 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.
