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: The present invention relates to method, system and electronic communications device for providing group scan for mobile devices located in overlapping active geofences. A method comprises, at one of a mobile device and a radio controller device in an infrastructure associated with the mobile device: determining a current location of the mobile device; identifying a plurality of active geofences having definitions that include the determined current location of the mobile device; accessing a geofence mapping that assigns, for each of the identified plurality of active geofences, one of a plurality of different priority levels and one of a plurality of different talkgroups; monitoring each of the plurality of different talkgroups for active calls as a function of the different priority levels; identifying a subset of the plurality of different talkgroups from the plurality of different talkgroups in the geofence mapping having an active call and, for each talkgroup in the subset, a particular talkgroup associated with a highest priority geofence; and joining the mobile device to the particular talkgroup.

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: 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: 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.

Abstract: A multi-system priority scan process including maintaining, at a mobile station (MS), a scan list including channels associated with talkgroups, the talkgroups including one or more trunked radio system talkgroups and one or more conventional radio system talkgroups. The MS negotiates, with a trunked radio system, a working channel for a particular trunked radio system talkgroup out of the trunked radio system talkgroups, the working channel being a traffic channel that the trunked radio system will first attempt to assign a call for that talkgroup. During a subsequent scan for talkgroup for activity associated with the particular trunked radio system talkgroup, the MS switches to the working channel and determines if a carrier is present on the working channel, without switching to a control channel of the trunked radio system to scan for activity associated with the particular trunked radio system talkgroup.

Abstract: In at least one embodiment, a radio access network (RAN) device maintains a proxy mapping table (PMT) of any mobile radios that are currently registered with the RAN via a mobile subscriber unit (MSU). The PMT indicates, for each mobile radio listed in the PMT, the particular MSU via which that particular mobile radio is registered with the RAN. The RAN device receives a first service request for a first mobile radio that is listed in the PMT as being registered with the RAN via a first MSU and, in response to receiving the first service request, makes a determination that an air-interface link is available for communication between the RAN and the first MSU. In response to making the determination, the RAN device communicates the first service request via the available air-interface link to the first MSU for delivery to the first mobile radio.
