Abstract: Methods and systems for controlling group communications using a mobile device includes detecting a motion of the mobile device corresponding to a user placing the device on a surface, maintain a communication session with another mobile device while the user is detected in proximity to the first mobile device, and entering a non-active communication mode when the user is not detected in proximity to the device. The communication session may be maintained for a time-out period before entering the non-active mode. Further methods and systems include transitioning to a non-active communication mode in response to detecting a motion of the mobile device corresponding to a user placing the device on a surface.

Abstract: Methods and systems of communication using a mobile device include communicating with other mobile devices over an initial communication channel, detecting a first motion of the mobile device moving from a first position to a second position, establishing a second communication channel with the other mobile devices in response to the detected first motion, and communicating with the other mobile devices over the second communication channel. In an example, the initial communication may be a half-duplex communication channel, and the second communication channel may be a full-duplex communication channel. In another example, the initial communication may be a full-duplex communication channel, and the second communication channel may be a half-duplex communication channel.

Abstract: Methods and systems of communication using a mobile device include detecting a motion of a mobile device corresponding to a user action, in response to the detected motion, initiating a half-duplex group communication application, and displaying visual feedback associated with the half-duplex group communication application on a display screen of the mobile device.

Abstract: Methods and systems of communication using a mobile device that include detecting a movement of the mobile device associated with transitioning from speaker phone mode to earpiece mode, or vice versa, and in response to detecting such movement, automatically transitioning the device to a different mode of operation. The detected action may be the motion and/or positioning of the device handset, such as the movement of the handset towards or away from the user's ear, and/or the placement of the handset on a surface in a face-up or face-down position. Further methods and systems for transitioning between communication pathways and security modes in response to a detected movement of the mobile device.

Abstract: Embodiment methods and systems include external hardware that can be fitted to a wireless communication device that stores a communication application, communication presets and/or data that are downloaded to the wireless communication device where it may be implemented to optimize group communications on the wireless devices. The wireless device may be coupled to an external case configured with a physical button that enables group communication such as push-to-talk and other push-to-experience capabilities. Optimizations for push-to-talk communication may be implemented in a push-to-talk mode in response to detecting connection to the external hardware. Signaling between the external case and the wireless device allows detection of the switch to (or from) push-to-talk mode when a user depresses (or releases) the hard key.
