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.
