Abstract: A device, method and system for scanning communication systems of different types is provided. A mobile device comprises: first and second transceivers to communicate first and second communication systems of different types; a memory storing first and second scan lists for scanning first and second channels on the first and second communication systems; and a controller configured to: communicate, using the first transceiver, an indication of the first and second scan lists to a gateway device configured as a proxy for the mobile device to communicate with the first communication systems; receive, using the first transceiver, from the gateway device, a reply indicating that the gateway device is capable of scanning the first communication systems using the first scan list, but is not capable of scanning the second communication systems; and control the second transceiver to scan the one or more second communication systems using the second scan list.

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 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: One example radio frequency (RF) site controller is configured to communicate with a first communication device over a control channel to establish a traffic channel over which the first communication device is configured to communicate with a second communication device. The RF site controller may control the control channel to switch between operating in (i) a keyed state (in other words a full-power state) for a first dynamic period of time and (ii) a de-keyed state (in other words, a lower-powered state) for a second dynamic period of time. At least one of the first dynamic period of time and the second dynamic period of time may be based on a characteristic of at least one of a group consisting of a coverage area being serviced by the RF site controller and one or more communication devices being serviced by the RF site controller.

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 device, system and method for determining a prioritized list of communication groups is provided. A computing device monitors current call statistics of a plurality of communication groups, the communication device assigned to the plurality of communication groups. The computing device, based on a comparison of the current call statistics with historical call statistics of the plurality of communication groups, generates a prioritized list of the plurality of communication groups. The computing device transmits, to the communication device, the prioritized list. The communication device may render the list for selection of a communication group, and/or automatically change to a highest priority communication group of the prioritized list, and/or when bandwidth of a current site is unavailable to communicate on the highest priority communication group, roam to a site with available bandwidth to change to a highest priority communication group in the prioritized list.

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: 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。

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.
