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.

Systems and methods for controlling Quality-of-Service ('QoS') in a Virtual Private Network ('VPN') in a transport network providing a plurality of QoS bearers. The methods involve: establishing, between two VPN endpoints, a plurality of VPN tunnels through the transport network, including at least a default VPN tunnel associated with a first QoS bearer and an alternate VPN tunnel associated with a second QoS bearer; receiving and analyzing a data block; applying a VPN policy to assign the data block to either default VPN tunnel or alternate VPN tunnel; and encapsulating the data block in a transport data block including at least one indicator. The indicator specifies whether the transport data block is to be communicated by the transport network using the first QoS bearer or second QoS bearer.

Multi-tunnel virtual private network

A method for registration and maintenance of a data connection using a proxy wireless network service involves registering a multi-network terminal on a first network that is made up of a first network infrastructure. The method includes transmitting registration information for a second network to a proxy component that is part of the first network infrastructure. The transmission of the registration information causes the proxy component to forward said registration information to an agent component that is part of the second network that is made up of a second network infrastructure. The method also includes receiving a registered service from the second network based on the registration information that was transmitted to the first network infrastructure. The method also includes transmitting a message to the second network and receiving the registered service from the second network in response to the message.

A system and method for assigning communication cells to servers in a cellular communication system. The method includes determining an affinity between a communication cell and a plurality of servers and assigning the communication cell to one of the plurality of servers based on the determined affinity.

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.

Cellular network

A wireless communication network is provided that includes a plurality of communication cells each defined by at least one communication coverage area and a plurality of access points each corresponding to a different one of the plurality of communication cells. Each access point is configured to communicate on a first frequency with at least one of (i) a subscriber in the at least one communication coverage area in a first communication cell and (ii) a subscriber in a second communication cell. Each access point is further configured to communicate on a second frequency with an access point in a third communication cell.

A transcoder architecture and method for transcoding in land mobile radio (LMR) systems are provided. The LMR system includes a first communication site configured to communicate using a first LMR communication protocol and a second communication site configured to communicate using a second LMR communication protocol. The LMR system further includes a transcoder configured to receive LMR content from the first communication site communicated using the first LMR communication protocol and digitally convert the LMR content to the second LMR communication protocol to be communicated to the second communication site.

Transcoder architecture for land mobile radio systems

A method for distributing group secrets (e.g., group ID and password combinations) for use in communication systems such as trunked radio communication systems. A user group record containing one or more group secrets is encrypted at an administrator using a user secret (e.g., a user ID and password combination) known to the administrator and to a communication device. The encrypted user group record is then distributed to the communication device where it is decrypted using the user secret.
