Abstract: A process for dispatcher monitoring of an electronic digital assistant (EDA) in a group-based mobile radio system includes first receiving, at a radio controller from a mobile radio, a request to establish an EDA call for interacting with an EDA. Identifying one of (i) a primary talkgroup to which the mobile radio is affiliated and (ii) an agency to which the mobile radio belongs. Selecting or creating an EDA talkgroup, different from the primary talkgroup, through which the mobile radio may interact with the EDA. Identifying one or more, but less than all, dispatch consoles that are (i) subscribed to monitor the primary talkgroup of the mobile radio or (ii) a member of a same agency as the mobile radio. Adding the EDA, mobile radio, and identified dispatch consoles to the EDA talkgroup. And causing the EDA call to be established.

Abstract: A method and system to avoid flooding a control channel after the end of a system-wide call is provided. A Land Mobile Radio (LMR) site tracks active channel assignments. The LMR site also receives a system-wide call request. Upon receiving the system-wide call request, a snapshot of the channel assignments is taken. When the LMR site receives an indication that the system wide call request has ended, the LMR site receives a de-assign complete message.

Abstract: A computer apparatus and computer-implemented apparatus for logging audio to an audio logger. Audio is transmitted from a source communication device. At least one receiving communication device receives the audio. The audio is logged to an audio logger, for example by the source communication device and the receiving communication device. A hash of the audio is computed and the hash of the audio and communication parameters related to the audio are stored in a blockchain.

Abstract: Reduction of audio truncation when transcoding speech data from one coding format to another. Embodiments include receiving packets of a first communication session containing first encrypted speech data encoded according to a vocoder of a first type and encrypted using an encryption protocol, and containing a first encryption protocol identification information distributed among the received packets. Further embodiments include extracting the first encryption protocol identification information from the received packets and processing the received packets based on the first encryption identification information. Embodiments include transmitting one or more voice header packets containing a second encryption protocol identification information in a second communication session as well as transmitting packets in the second communication session containing second encrypted speech data encoded according to a vocoder of a second type.

Abstract: A method for extending the connection time of talkgroup radios in a talkgroup conversation based on historical talkgroup statistics is provided. A talkgroup conversation request intended for a talkgroup is received from a first mobile unit. A group call grant message is sent to radios that are members of the talkgroup. The group call grant message initiates the talkgroup conversation with a first talkgroup call and includes an extended connection time value. Once it is determined that the first talkgroup call has ended, all radios that are members of the talkgroup are kept in a connected state. An extended connection timer utilizing the extended connection time value is started. Upon expiration of the extended connection timer, all radios that are members of the talkgroup are set to an idle state.

Abstract: A scheduling component associated with a data channel configures initial reserved bandwidth allocations for each agency permitted access to a shared data channel. When sufficient bandwidth is available on the shared data channel to meet all bandwidth requests, the scheduling component schedules access to available random access slots on the shared data channel. When an agency accesses a scheduled random access slot, the agency is able to reserve additional reserved slots on the shared data channel for data transmission on an on-demand basis. The scheduling component enables bandwidth management controls when one or more requests for the additional reserved slots on the shared data channel cannot be fulfilled due to insufficient available additional reserved slots on the shared data channel and controls access to the shared data channel by distributing limited access permissions for future available random access slots to agencies permitted access to the shared data channel.

Abstract: A method and apparatus for providing acknowledgment information for radio communication devices in a wireless communication system. A base station receives a plurality of units of data each respectively transmitted by one of a plurality of radio communication devices on one of a plurality of predetermined communication slot positions of a first channel. The base station, in response to receiving the data messages, sends a control message on a communication slot position of a second channel. The control message includes acknowledgment information having a plurality of positional acknowledgment indicators. Each radio communication device receives the control message and uses acknowledgment position mapping information to identify one or more positions within the plurality of positional acknowledgment indicators that contains an acknowledgment to the respective units of data it transmitted on the corresponding predetermined communication slot positions of the first channel.
