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: 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: 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: A method for communicating half-rate encoded voice frames. The method includes receiving, by a digital signal processor, a half-rate encoded voice frame. The method further includes determining, by the digital signal processor, a network access code. The method further includes encoding, by the digital signal processor, a network identifier based on the network access code. The method further includes scrambling, by the digital signal processor, the network identifier to generate a scrambled network identifier. The method further includes generating, by the digital signal processor, an erasure pattern. The method further includes generating, by the digital signal processor, a half-rate embedded voice code word based on the erasure pattern and the half-rate encoded voice frame. The method further includes generating, by the digital signal processor, a half-rate embedded logical data unit based on the half-rate embedded voice code word and the scrambled network identifier.
