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.

Abstract: A method and system for tracking an object of interest in a talkgroup. The method includes receiving a first image stream including the object from a first portable communication device associated with the talkgroup. The method includes detecting the object in the first image stream, determining a first view angle associated with the object's position in relation to the first device, and determining a second view angle associated with the object's position in relation to a second portable communication device. When a difference between the first angle and the second angle is below a threshold, a first modified image stream is generated by highlighting the object in the first image stream. When the difference between the first angle and the second angle is above the threshold, a second modified image stream is generated by highlighting the object and indicating a relative direction to the object from the second device.

Abstract: Methods, and apparatus for managing a communication group. One method includes forming a communication group of one or more portable communications devices based on a first object of interest and identifying a second object of interest based on the first object of interest. The method also includes determining whether an image feed includes the second object of interest and when the image feed includes the second object of interest, adding a portable communications device associated with the image feed to the communication group.

Abstract: A method and apparatus for detecting a stale number. A stale number detection device obtains a call number, a call number contact creation date, and a call number issue date for the call number. The stale number detection device determines that a stale number state exists when the call number issue date is later than the call number contact creation date. The stale number detection device generates a stale number notification based on the stale number state.

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.
