Abstract: A wireless PTT communication system may include mobile wireless PTT communications devices, each configured to send a PTT call request, a wireless network coupling the mobile wireless PTT communications devices, and a PTT server. The PTT server may be configured to when a number of the mobile wireless PTT communications devices in a given talkgroup is greater than or equal to a first threshold, then cause each mobile wireless PTT communications device of the given talkgroup to report a respective location. The PTT server may be configured to when a number of the mobile wireless PTT communications devices in the given talkgroup is less than the first threshold, then disable each mobile wireless PTT communications device of the given talkgroup from reporting the respective location.

Abstract: Systems (100) and methods (200) for using Multimedia Broadcast Multicast Services (“MBMS”) transport bearers in a network. The methods comprise: performing first operations by a computing device (102) to setup an MBMS transport bearer over which media (e.g., voice) is able to be communicated to a plurality of clients (110-136) via multicast transmissions; and performing second operations by the computing device to inform the plurality of clients of the MBMS transport bearer's establishment. The second operations include, but are not limited to: determining an immediate need of each client of the plurality of clients based on weighted attributes (e.g., priority group affiliating, and/or group status); assembling a prioritization list of clients based on the determined immediate needs of each client; and delivering unicast messages to the clients in accordance with an order specified by the prioritization list.

Abstract: A wireless communications system may include different wireless communications networks, an application server, and an intermediate server configured to communicate with the application server. The wireless communications system may also include a mobile wireless communications device configured to communicate with the intermediate server over each of the different wireless communications networks to determine a selected wireless communications network. The mobile wireless communications device may also be configured to communicate with the application server via the intermediate server over the selected wireless communications network.

Abstract: Systems (200) and methods for providing voice communications over a cellular network (204, 212). A call setup message is communicated from a first communication device (FCD) to a second communication device (SCD) on a first communications channel (FCC) in a cellular network (CN) at a first data transfer rate (FDTR). In response to the call setup message, a stimulator packet is communicated to the CN on FCC at FDTR. The stimulator packet includes data of an amount that equals or exceeds a threshold value. In response to the stimulator packet, FCD (202, 214) and CN transition from a first channel mode to a second different channel mode. In the second channel mode, data is transmitted on a second communications channel (SCC) in CN at a second data transfer rate (SDTR) different than FDTR.
