Abstract: A method and system for completing a voice call in a cloud-based communication system is provided. A cloud-based group voice call service receives a group voice call initiation request from a first mobile device located at a first communication system. The group voice call initiation request is a request to complete a group voice call with a second mobile device located at a second communication system. The cloud-based group voice call service allocates resources at the first communication system and the second communication system. The cloud-based group voice call service issues a call grant to the first mobile device located at the first communication system and also issues a call response to the second mobile device located at the second communication system in order to complete the voice call.

Abstract: A method and system for processing a Push To Talk (PTT) call at an alternate bearer gateway. The alternate bearer gateway is connected to a Land Mobile Radio (LMR) Core Network and a Broadband Network. The alternate bearer gateway receives a PTT message from either the LMR Core Network or the Broadband Network. The PTT message includes a talkgroup identifier and a message. When the PTT message is received from the LMR Core Network, the alternate bearer network determines at least one Broadband talkgroup member using the talkgroup identifier. The alternate bearer gateway sends the message to the Broadband talkgroup member via the Broadband Network. When the PTT message is received from the Broadband Network, the alternate bearer gateway sends the message to the LMR Core Network.

Abstract: A device, system and method for throttling network usage of a mobile communication device is provided. A mobile communication device comprises: a communication unit configured to wirelessly communicate over a network; a memory storing one or more applications that use the communication unit to communicate via the network; and a controller communicatively coupled to the communication unit and the memory. The controller receives, via the communication unit, network data indicative of current network usage. The controller dynamically throttle usage of the communication unit by the one or more applications according to the network data.

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: Methods and apparatus for supporting multiple emergency users in a push-to-talk group. The methods include receiving a first emergency alert from a first user device in the push-to-talk group; receiving a second emergency alert from a second user device in the push-to-talk group; causing the first emergency alert and second emergency alert to be provided to each of the console devices in the push-to-talk group; receiving, from the first user device, a first communication and receiving, from the second user device, a second communication; causing the first communication and the second communication to each of the console devices in the push-to-talk group. The methods further include receiving, from a first console device, a selection of one of the first user device and the first emergency alert; and, in response subsequently selectively routing a third communication from the first user device to the first console device and not to a second console device in the push-to-talk group.

Abstract: A method and talkgroup server for extending a battery life in a subscriber unit is provided. A time sync at a triple TSBK boundary is maintained, the triple TSBK boundary being associated with a talkgroup. The triple TSBK window is calculated based on the time sync and configuration data. A talkgroup call request is granted for the talkgroup using a talkgroup call grant. A first transmission of the talkgroup call grant is targeted in the triple TSBK window associated with the talkgroup.

Abstract: A method and subscriber unit provide mission critical talkgroup service while minimizing truncation and delay when at least one member talkgroup radio is on a Broadband LTE (Long Term Evolution) system. A dual-mode subscriber unit preferably obtains LMR coverage map data to predict the entry point and remaining duration for when the subscriber unit will operate in the backup LTE system. The subscriber unit falls back to the LTE system when the subscriber unit is out of the coverage area of the LMR system. Because the subscriber unit set the connected state prior to using the LTE network and continuously optimizes RRC mode parameters, audio truncation and call delay are greatly reduced without draining the battery of the subscriber unit.

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, device, and system for scheduling a status update in a time division multiple access (TDMA) communication system. One method includes transmitting, with a call controller, scheduling information to the each of the plurality of communication devices via an outbound time slot associated with a control channel of a local common TDMA channel to schedule the each of the plurality of communication devices to transmit the status data in a pre-determined sequence. The method also includes receiving the status data from at least one of the plurality of communication devices in the pre-determined sequence.
