Abstract: Embodiments of systems and methods for implementing data sovereignty safeguards in a distributed services network architecture are disclosed. Embodiments of a distributed services system may have a number of distributed nodes that each implements a set of services. When a user requests a service at a particular node of a distributed services system, the node is configured to determine if that node is not (or is) data sovereign for a region associated with the user. If the node is not data sovereign for the user's region, the user may be directed to a corresponding service at a node of the distributed service system that is data sovereign for the user's region.

The cloud-based fault management service performs smart analytics utilizing the first fault update to change the second communication system.

Abstract: When a land mobile radio connection is unavailable for a subscriber device, the subscriber device may use an alternative connection. A gateway may be used to allow the subscriber device to connect to the zone controller of a land mobile radio network via an alternative network. The gateway may be configured to perform remote scan and priority operations, similar to the scan operations the subscriber device would ordinarily perform locally. The gateway may receive a scan list from the subscriber device and call notifications from the zone controller. Using the scan list, the gateway may evaluate the call notifications, determine whether they should be sent to the subscriber device, and send them to the subscriber device over the alternative connection. The gateway may be able to adjust the remote scan and priority operations based on receiving different scan lists from the subscriber device or by generating different versions itself.

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 method and system for providing a fallback solution in a multi-tenant communication system is provided. A cloud-based call processing service receives a voice call initiation request from a first mobile device located at a first communication system. The voice call initiation request includes a request to complete a voice call with a second mobile device located at a second communication system. Resources are allocated at the first communication system and the second communication system. The cloud-based call processing service establishes a call between the first mobile device and the second mobile device. At some point the first communication system determines that it should fallback to single site operation. In fallback mode, call processing functionality is performed at the first communication system for the first mobile device.

Abstract: A method and system for completing a call between a first mobile device located at a first communication system and a second mobile device located at a second communication system is provided. A call initiation request including a request to complete a call with the second mobile device is received at a Radio Access Network (RAN) Adaptor (RA) from the first mobile device. The RA determines RAN-specific access parameters for the first mobile device and the second mobile device. The RA sends a call processing call initiation request including the RAN-specific access parameters and call initiation information for the first mobile device and the second mobile device to a cloud-based group call service. The RA establishes resources specific to the RAN in the RA. The resources include first resources at the first communication system and second resources at the second communication system.

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: When a land mobile radio connection to a land mobile radio network is unavailable for a land mobile radio subscriber device, the subscriber device may connect to an alternative network using an alternative connection. The subscriber device may send a copy of a scan list to a gateway configured to perform remote scan and priority operations, similar to the scan operations the subscriber device may ordinarily perform locally. Using the received scan list, the gateway may evaluate the call notifications, determine whether they should be sent to the subscriber device, and send them to the subscriber device over the alternative connection to the alternative network. The subscriber device may receive call notifications over the alternative connection and join active radio calls over the alternative connection. The subscriber device may be able to alter remote scan and priority operations by dynamically altering and sending the scan list over the alternative connection.

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 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: 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.
