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.

Abstract: A method to control multiple radio access bearers is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a radio network subsystem in a wireless communication network by first and second bidirectional radio access bearers. The mobile wireless communication device transmits a data packet on an uplink of the first bidirectional radio access bearer to the radio network subsystem. When the data packet is not correctly received by the radio network subsystem, the mobile wireless communication device retransmits the data packet repeatedly. After N retransmissions of the data packet, the mobile wireless communication device releases the first bidirectional radio access bearer while maintaining the second bidirectional radio access bearer. The first bidirectional radio access bearer provides a channel to transport packet switched data, and the second bidirectional radio access bearer provides a channel to transport circuit switched data.

Abstract: Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.

Abstract: Apparatus and methods to improve compatibility between a primary wireless device including multiple subscriber identity modules (SIMs) and a cellular capable secondary wireless device are disclosed. The cellular capable secondary wireless device pairs with the primary wireless device, which provides a configurable option to allow mobile terminated connections and/or messages to be received at the cellular capable secondary wireless device for multiple SIMs when the cellular capable secondary wireless device is not within proximity of the primary wireless device and is being worn. The primary wireless device indicates conditional forwarding to a second wireless network associated with a second SIM and adjusts notification alerts to reduce time for forwarding when the cellular capable secondary wireless device is separated from the primary wireless device and in use.

Abstract: Method and apparatus to trigger a handover of a mobile device from a serving cell to a neighbor cell based on signal quality are disclosed. The mobile device measures signal strength and signal quality for the serving cell. When the signal strength exceeds a network-defined threshold and the signal quality falls below a mobile device defined threshold, the mobile device measures at least one neighbor cell. When a neighbor cell exceeds the network-defined threshold for signal strength and also meets the mobile device defined signal quality threshold, the mobile device sends a measurement report to the serving cell to trigger the handover. The measurement report includes modified values that indicate the serving cell does not meet network-defined threshold values and that the neighbor cell outperforms the serving cell.
