Abstract: A communication device receives coordinates for an inner area and an outer area associated with a geo-fence. The communication device determines its current location coordinate and determines how the current location coordinate relates to the coordinates for the inner area and the outer area. The communication device discovers, using the current location coordinate and the coordinates for the inner area and the outer area, that the communication device is located outside of the inner area and inside of the outer area. Responsive to the discovering, the communication device sends a query to a network equipment to determine the current location of the communication device relative to the geo-fence. The communication device receives information associated with an intermediate area and uses the information associated with the intermediate area to determine the current location of the communication device relative to the geo-fence.

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: Improved incident device pairing for safety and security of first responders entering an incident scene area associated with an incident is provided. An electronic computing device (ECD) transmits a request to scan for nearby pairable mobile computing devices to each of a plurality of mobile computing devices (MCDs) associated with the incident. The ECD receives identity information from each MCDs setting forth identities of other MCDs reachable via a short-range wireless communication link. The ECD accesses equipment mapping information that sets forth equipment associated with the MCD or user thereof and identifies a plurality of pairs of MCDs for entering the incident scene area as a function of the identity and equipment mapping information. The ECD then transmits a short-range pairing instruction to each MCD identifying the other mobile computing device in the pair and instructing the MCDs to pair with one another via their short-range wireless communication link.

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: A method and an electronic device for inputting handwriting character are provided. The electronic device comprises a touch screen, a memory, and a processor. The processor is configured to perform the functions of the method. The method comprises steps of: adding a handwriting input on the touch screen; detecting a position of an initial point of the handwriting input; determining an input area for the handwriting input among the plurality of input areas of the touch screen based on the position of the initial point of the handwriting input; determining an operation of the handwriting input based on the position of the initial point of the handwriting input and performing the determined operation; and upon completion of the handwriting input, recognizing the input as a character and displaying the recognized character in the determined input area on the touch screen.

Abstract: A method and server for broadcasting a data file to talk groups. The method includes fragmenting 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: 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 transmits, 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.
