Abstract: Techniques for radio frequency uplink performance assessment utilizing downlink erasure frame analysis are provided. An indication of if a received frame has been determined to be an erasure frame is received from a plurality of receiver wireless communications devices. The indications of if the received frame has been determined to be an erasure frame are aggregated. The frame identified by the frame identifier is declared to be an erasure frame when at least one of the plurality of wireless communications devices has indicated the received frame has been determined to be an erasure frame. That an error occurred on an uplink between the sender wireless communication device and the RAN is determined when the frame is declared an erasure frame.

Abstract: A communication system (100) formed of a radio management system (104) interoperates with a radio management codeplug database (106) and a confusability analyzer (108) for the creation and storage of voice recognition target strings for uploading to one or more land mobile portable radios (110) prior to field-deployment. Once the radios are deployed to the field, unrecognized voice command entries are determined, stored locally at the portable radio, and uploaded to cloud based storage (122). Analysis of the cloud based data is performed through a voice control analytics engine (124) to detect patterns associated with the unrecognized voice commands. The unrecognized voice command pattern is processed though a resolution action engine (126) to generate one or more resolution actions for the pattern.

Abstract: A virtual assistant (VA) integrity monitor is provided to interface with a computer aided dispatch (CAD) center to ensure reliability of a VA server operating with a communication system. The VA integrity monitor generates a test query which is perceived by the VA server as being a real, user-generated query to which the VA server responds. The VA integrity monitor verifies that a response provided by the VA server meets predetermined criteria and communicates a result to the CAD center. The CAD center advantageously recognizes that the request and the response are based on a simulated test and therefore does not take action on either the query or the response. When the VA integrity monitor verifies that a response provided by the VA server does not meet the predetermined criteria, the CAD system can send out an alert.

Abstract: A system, apparatus, and method are provided for integrating a virtual assistant (VA) subsystem (114) with a repeater (102) of a communication system (100). A conventional repeater (102) containing repeater receiver (108), a repeater controller (110), and a repeater transmitter (112) communicate with a plurality of radios (120, 130). The repeater controller (110) places the repeater (102) into a repeater mode or a virtual assistant mode based on a squelch code associated with an incoming radio signal. The system provides virtual assistant operation, prioritization of mission critical calls, interrupt, and privacy on a single conventional channel. The incorporation of the virtual assistant into a conventional repeater system has been advantageously achieved without the use of additional infrastructure or additional licensed channels.

Abstract: A technique for a secondary communication system to utilize spectrum designated to another (or primary) communication system is provided. By ranking a plurality of secondary base stations based on base station transmit power, calculated required transmit power and path loss, a set of criteria is developed for selecting a highest ranked secondary base station for operation within a primary's spectrum. The ranking may be adapted based on mobility of the secondary's subscriber; and as such the secondary system communicates within the primary's spectrum using the adaptively ranked base stations. Channel selection may also be ranked. The technique and apparatus allows a cognitive radio (CR) network to operate within an incumbent network's spectrum.

Abstract: A radio configured to dynamically control cancellation of undesired signals in an audio stream. The radio includes a noise cancellation processor configured to receive an audio stream from a user and to alter information in the audio stream by filtering out undesired signals in the audio stream. The radio also includes a receiving component configured to receive a data packet from a remote device, to retrieve configuration information from the data packet, and to dynamically apply the configuration information, while the radio is being used by a user, to settings associated with the noise cancellation processor. A dynamically enabled noise cancellation processor suppresses undesired signals associated with a subsequent incoming audio stream provided by the user and transmits at least one of an altered audio stream or an unaltered audio stream to the remote device.
