Abstract: Systems and methods for broadband failover in land mobile radio networks. One method includes operating a first communication interface of a converged communication device to execute a first communication between the device and a first network using an LMR modality. The method includes determining a plurality of radio communication characteristic values for each of a plurality of sites of the first network and generating a fallback threshold for a home site of the device based on the plurality of radio communications characteristics. The method includes determining whether a current radio communication characteristic value associated with a home site of the device exceeds the fallback threshold, and, when the current radio communication characteristic value does not exceed the fallback threshold, operating a second communication interface of the converged communication device to execute a second communication between the device and a second network using a non-LMR modality.

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 system for authenticating a communication device with an application server. The application server includes a gateway registration port, a gateway server port, and an electronic processor. The electronic processor is configured to receive, via the gateway registration port, a registration request, including a unique identifier, from a first device over a first communications network that operates in accordance with a first modality and receive, at the gateway server port, an access request including an identifier from an unknown device over a second communications network that operates in accordance with a second modality. The electronic processor is configured to compare the second identifier with the first identifier to determine if the identifiers match, grant the unknown device access when the identifiers match, and deny the unknown device access when the identifiers do not match.

Abstract: An apparatus for simultaneously receiving incoming messages on at least two channels in a multi-channel device, wherein a first incoming message is received on a first channel of the at least two channels according to a first protocol. Responsive to receiving the first incoming message, outgoing messages are transmitted on the first channel while the incoming messages are simultaneously received on a second channel. The outgoing messages to be sent according to the first protocol are queued in a transmitter. The transmitter also monitors at least one data stack that is used for transmitting messages according to a second protocol for transmit opportunities. Responsive to detecting a transmit opportunity, the transmitter transmits an optimal number of the outgoing messages within the duration of the transmit opportunity. The outgoing messages are transmitted on the first channel without affecting incoming messages received on the second channel.

Abstract translation: 一种用于在多信道设备中的至少两个信道上同时接收传入消息的设备，其中根据第一协议在所述至少两个信道的第一信道上接收第一传入消息。 响应于接收第一传入消息，在第一信道上发送传出消息，而在第二信道上同时接收传入消息。 根据第一协议要发送的传出消息在发射机中排队。 发射机还监视至少一个用于根据用于发送机会的第二协议来发送消息的数据栈。 响应于检测发送机会，发射机在发送机会的持续时间内发送最佳数量的输出消息。 输出消息在第一信道上发送，而不影响在第二信道上接收的传入消息。
