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.

Systems () and methods () for using Multimedia Broadcast Multicast Services ('MBMS') transport bearers in a network. The methods comprise: performing first operations by a computing device () to setup an MBMS transport bearer over which media (e.g., voice) is able to be communicated to a plurality of clients (-) 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.

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.

A system and method for heartbeat signal generation are provided. The method includes determining a communication condition and generating heartbeat signals based on the determined communication condition. The system includes a plurality of communication cells and at least one communication device configured to generate heartbeat signals. A rate of generating the heartbeat signals is based on one of (i) a service priority or user group and (ii) communication requirements for a network type for each of the plurality of communication cells.

Systems and methods for controlling congestion in a cellular communication system () are provided. A method includes measuring an inter-arrival time for a plurality of communication packets in at least one user equipment within the communication cell and calculating an average value for the measured inter-arrival times (). The method further includes determining the average value over each of a plurality of time periods and identifying a congestion condition when the determined average value exceeds a predetermined value over the plurality of time periods ().

System and method for controlling congestion in cells within a cellular communication system

A system and method for managing communication in a cellular communication system are provided. The method includes measuring communication conditions within at least one communication cell of the communication system and estimating congestion within the at least one communication cell of the communication system based on the measured communication conditions. The method further includes adjusting communication links within the at least one communication cell based on the estimated congestion.

Systems () and methods for providing voice communications over a cellular network (). 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 () 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.
