Abstract: A portable communication device provides a pseudo full-duplex communication mode by unmuting a microphone, enabling acoustic echo cancellation (AEC) and decreasing speaker volume when a push-to-talk (PTT) button is pressed, and by muting the microphone during release of the PTT button.

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 methods and devices for secure pairing for devices with NFC tags equipped with authentication are provided. In one aspect a device with a passive near field communication tag including a private key for authentication is provided. The device may send a challenge request to a host device including an active NFC tag via a wireless communication protocol. The challenge request may be combined with a shared secret value known to the device and the host device to create a challenge request seed. The challenge request seed may be combined with the private key to compute a verified challenge request response. A challenge request response may be received from the host device via the wireless communication protocol. The challenge request response and verified challenge request response may be compared to authenticate the host device to the device.

Abstract: Improved connectivity between a portable communication device and an accessory is provided through the configuration of a USB type interface. Independent control of a mission-critical subsystem and auxiliary subsystems allow for mission-critical audio and push-to-talk (PTT) to be maintained even in the event of a fault condition within the system. The configurability aspect of the interface allows for additional mission-critical input features to be configured into independent mission-critical subsystems.

Abstract: A method and apparatus for operation of a remote speaker microphone over an expanded temperature range. By monitoring a temperature of the communication device, a temperature sensitive microprocessor can be disabled above a predetermined extreme temperature, thereby allowing control of an audio path of the communication device to be modified. Microphone and speaker signals of the communication device can be switched or rerouted to an electronic path capable of operating above the predetermined extreme temperature for expanded operation while previous microprocessor controlled digital and analog audio circuits are shut down.

Abstract: A portable communication system (100) comprises a portable radio (102) and a radio accessory (106) coupled through an interface cable (108). The interface cable (108) provides an electronic interface for remote access to radio functions at the radio accessory (106). The interface cable (108) further provides a temperature sensor (110) integrated therein for monitoring environmental conditions external to the portable communication system. The portable communication system (100) generates user notifications indicating extreme temperature conditions. Notifications of extreme temperature conditions may also transmitted from the portable communication system (100) to other radios, such as a land mobile radio (120), dispatch center (130), or other radio (140) operating within a communications network.

Abstract: A communication system (100) formed of a portable radio (102) and radio accessory (106) is provided in which the accessory (106) provides emergency strobe and flashlight modes, the flashlight mode further providing a low battery indicator. Strategic control of lighting triggers and patterns allows for a single high intensity LED (132) to be used for both emergency strobe and flashlight modes, with minimized impact on battery life.
