Abstract: A system and method for prioritizing a wireless communication to a portable communication device (102). In one example, a sensor (121) includes an electronic processor configured to capture an over-the-air identifier (404_1) of a portable communication device (102), determine a capture parameter based on at least one of a count of a number of times of capturing the over-the-air identifier and a last time of capturing the over-the-air identifier of the portable communication device (102), assign a priority level (414_1) to the portable communication device (102) based on the capture parameter, and prioritize the wireless communication between the sensor and the portable communication device (102) based on the priority level (414_1) assigned to the portable communication device (102).

Abstract: Missed voice stream portions are replayed at a late entry subscriber device (SD) in a wireless radio network. The SD joins a voice call on a radio channel via a base station and detects that it is late to the call. The SD continues to receive a remaining portion of the call and plays back the portion of the call. The SD detects an end of the voice call, and (i) transmits a request message including an indication of a first duration of the portion of the call received or (ii) detects a similar message from another SD. The SD then receives an indication of a total duration of the voice call and calculates a third duration as a function of the total duration and the first duration. The SD receives and plays back the missed portion of the call for the third duration.

Abstract: Disclosed herein are methods and systems for patching direct-mode talkgroups among dual-watch mobile radios. A mobile radio has first and second receivers, and is in a first talkgroup having a first channel. The mobile radio resides the first receiver on the first channel, and detects either a first patch event or a second patch event. The first patch event is an instruction for a first-channel session. The second patch event is an invitation for a second-channel session. Upon detecting the first patch event, the mobile radio transmits an invitation on the first channel and also on one or more other channels respectively associated with one or more other talkgroups, directing all recipients to the first channel. If the mobile radio detects the second patch event, the mobile radio resides the second receiver on the second channel.

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: 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.

Abstract: An incoming call from a source device having a source identifier is received at a receiving device and an indication of and request to accept the incoming call is provided at an output interface of the receiving device. A determination is made of whether this is a first time that the source device has called this receiving device or if the local address book is devoid of the source identifier or any associated contextual information associated with a user of the source device having the source identifier. If so, one or more databases of public safety incident information, call information, registration information, dispatch records, mobile application information, and location information is accessed and contextual information identified from the databases associating the source device with the receiving device. The contextual information is then provided at the receiving device while providing the indication of and request to accept the incoming call.

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 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.
