Abstract: A method and server for broadcasting a data file to talk groups. The method includes the data file into data blocks and broadcasting the data blocks to the talk groups. The method also includes detecting a voice call start event based on a first change is a received voice call status. The method further includes detecting a voice call end event based on a second change in the received voice call status. The method also includes generating a backlog item. The backlog item includes a subset of data blocks of the plurality of data blocks. The subset of data blocks were broadcasted on the broadcast data channel after the voice call start event and prior to the voice call end event. The method further includes broadcasting the subset of data blocks on the broadcast data channel upon detection of the voice call end event.

Abstract: Aggregating and segregating multiple digital vehicular repeaters. One exemplary method includes the steps of assigning a first serving digital vehicular repeater from a plurality of digital vehicular repeaters; receiving, via the first serving digital vehicular repeater, a first call request from a first portable subscriber unit; assigning the first call to a first channel; moving the first serving digital vehicular repeater and the first portable subscriber unit to the first channel; and assigning a second serving digital vehicular repeater from the plurality of digital vehicular repeaters.

Abstract: A method and apparatus for a first communication device for use with a first vehicle in a system for transmitting information about an incident occurring on a road. The first communication device includes a first receiver to receive an incident indicator. In one embodiment, a first electronic processor is electrically coupled to the first receiver and a first transmitter. The first electronic processor is configured to determine whether to relay a modified incident indicator to other vehicles. The first electronic processor is further configured to modify at least a portion of incident information included in the incident indicator to create the modified incident indicator. The first electronic processor is further configured to control the first transmitter to transmit the modified incident indicator to one or more other vehicles.
