Abstract:
A method and apparatus for a back channel implemented by a transmitting device in a half-duplex communication system includes monitoring for voice activity detection, indicative of an absence of human speech, while the transmitting device is transmitting on a half-duplex channel of the half-duplex communication system; transmitting a notification of a back channel opportunity to other devices on the half-duplex channel responsive to the voice activity detection; and switching to a receiving mode to receive data on the back channel while still maintaining control of the half-duplex channel. A method for a back channel implemented by a receiving device is also described.
Abstract:
Disclosed herein are methods and systems for token-based application management. In an embodiment, requests are received from applications for tokens that can be active or inactive. A token-interaction-directive pool is maintained in data storage, each directive having a triggering token, a target token, and one or both of triggering-token actions and target-token actions. Responsive to receiving a token request from an application, any directives having their triggering token equal the requested token and having their target token active are identified. A response plan that includes the actions in the identified directives is generated. Any triggering-token actions in the response plan are communicated to the requesting application, and any target-token actions in the response plan are communicated to each application that is authorized to access the corresponding target token.
Abstract:
A method and system for dynamically managing wireless pairing of a portable radio device and an accessory are provided. A multi-stage wireless pairing mode applies a first BT pairing stage that utilizes NFC and BT communication, while disabling low-priority, high-current communications of the portable radio device. The second BT pairing stage turns off the NFC pairing, maintains BT, and re-enables the low-priority, high-current communications. Any occurrence of a high-priority, high-current mission critical event disables the multi-stage pairing mode and services the event. User notifications and are dynamically managed to avoid user interference during the pairing.
Abstract:
A method and apparatus for expanding control switch selectivity in a portable communication system is provided. A rotary control switch is remapped based on the presence of two or more switches in the system thereby increasing the number of user selectable switch features, such as user selectable radio channels. The remapping can occur automatically without the need for hardware changes. The improved user interface can extend channel range selection in a portable communication system having a portable radio and radio accessory.
