Abstract: Example devices, systems, and methods for emulating a PTT device at an incident location are provided. An example server receives a request for a remote push-to-talk (PTT) device to be emulated at a target location in a vicinity of an incident, selects local communication infrastructure that supports public safety services for local PTT devices located near the target location, and ransmits, to the local communication infrastructure, instructions for the local communication infrastructure to register an emulated PTT device as a proxy for the remote PTT device at the target location.

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 apparatus for providing an audible identification of a device is provided herein. During operation, device identities will be determined for members forming a personal-area network (PAN). When information is conveyed by a device, a determination of whether or not to announce a device identification will be based on a combination of PAN members present. More particularly, when a certain combination of devices are members of the PAN, device identifications will be announced, otherwise, device identifications will not be announced.

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: 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 communications system and method of operation thereof. The communications system includes a communication network, a plurality of subscriber units and accessories, and a communications server. Each of the plurality of accessories are associated with and linked to one of the of subscriber units by a wireless connection. The communications server communicates with the plurality of subscriber units via the communication network, and is configured to obtain and maintain a plurality of data on each of the plurality of subscriber units, and generate a backup list identifying secondary subscriber units to which each of the plurality of accessories can link. Upon detecting a condition where communication drops below a desired level of service, the communication server is configured to identify a secondary subscriber unit from the first accessory's backup list and instruct the secondary subscriber unit to link with the first accessory.
