    Abstract: Systems and methods for reducing audio delay for mixed mode delivery of audio transmissions. One example system includes a communication interface communicatively coupled to a communication network, and an electronic processor. The electronic processor is coupled to the communication interface, and configured to receive, via the communication interface, a group call request for a talkgroup. The electronic processor is configured to transmit, in response to receiving the group call request, a call grant message to a plurality of subscriber units affiliated with the talkgroup. The electronic processor is configured to determine, using a machine learning algorithm, a subset of the plurality of subscriber units based on a call grant response time, and, while a transmission hold-off timer has not expired, when a call grant response has been received from each of the subscriber units of the subset, forward an audio transmission to the subset based on the group call request.

    Abstract: A device, system and method for determining a prioritized list of communication groups is provided. A computing device monitors current call statistics of a plurality of communication groups, the communication device assigned to the plurality of communication groups. The computing device, based on a comparison of the current call statistics with historical call statistics of the plurality of communication groups, generates a prioritized list of the plurality of communication groups. The computing device transmits, to the communication device, the prioritized list. The communication device may render the list for selection of a communication group, and/or automatically change to a highest priority communication group of the prioritized list, and/or when bandwidth of a current site is unavailable to communicate on the highest priority communication group, roam to a site with available bandwidth to change to a highest priority communication group in the prioritized list.

    Abstract: A method of assigning a priority to a portable communication device in a communication system. The method includes determining an incident profile. The incident profile defines an expected timeline having a first incident stage, a first role associated with the first incident stage, a second incident stage, and a second role associated with the second incident stage. The first role is different than the second role, and the incident profile indicates a desired priority rank for the first role and the second role. The method also includes assigning a priority rank to a first portable communication device when the first portable communication device corresponds to the first role during the first incident stage, detecting a transition between the first incident stage and the second incident stage, and assigning the priority rank of the portable communication device according to the second role during the second incident stage.

    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.

    Abstract: Scheduling resource reservations in a cloud based communications system. One embodiment provides a scheduling server for scheduling resource reservation in a cloud-based communication system. The scheduling server includes an electronic processor configured to monitor events outside of the cloud-based communication system to determine an occurrence of an incident and determine cloud computing resources to be allocated to consuming communication devices assigned to respond to the incident. The electronic processor is also configured to reserve the cloud computing resources such that the cloud computing resources are available to the consuming communication devices for responding to the incident.
