Abstract: A subscriber device joins a talk group and receives, via a control channel, parameters defining a plurality of assigned downlink data transmission periods associated with the talk group on a downlink short data channel. The subscriber device determines from the parameters when a next downlink short data transmission for devices in the talk group will be transmitted on the downlink short data channel. The subscriber device switches to the downlink short data channel during the next transmission period.

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: 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: 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: 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 method and apparatus for presenting a form to a user is provided herein. During operation, an incident type is determined along with a current location of a public-safety officer. This information is used to modify a form for easier filling by the public-safety officer. More particularly, fields of the form are provided in an order based on the incident type and location. Alternatively, the fields of the form may be highlighted based on the incident type and location.

Abstract: Fast channel deployment is achieved amongst subscriber devices (SDs) having an incident scene role at an incident scene. An SD detects an incident scene arrival trigger associated with arrival at an incident scene. Responsive to detecting the incident scene arrival trigger, the SD (i) tunes to a pre-configured incident channel or (ii) scans a plurality of channels for an incident channel and tunes to the incident channel once located. The SD receives, via the incident channel, an incident scene role to traffic channel mapping that maps a particular incident scene role associated with the subscriber device to a particular assigned traffic channel on which subscriber devices associated with a same incident scene role may communicate. The SD tunes to the particular assigned traffic channel as a function of the incident scene role to traffic channel mapping.

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.

Abstract: A process for selectively activating a guardian camera in response to detecting a distracted user includes first identifying an available camera external to a mobile computing device (MCD) having a field of view that incorporates a current location of a user of the MCD. The MCD then detects that a user's attention is substantially focused on a user interface of the MCD, and responsively transmits an instruction to the available camera to transition to a recording state and/or to begin monitoring an area surrounding the user for unexpected movements or objects. In response to the MCD detecting an indication that the available camera has recorded an unexpected movement or object in the area surrounding the user, the MCD takes a responsive action.

Abstract: A communication system is provided wherein multiple communication devices of a user may collaborate with each other via an extended virtual Personal Area Network (EVPAN). When the user exits his car and leaves one of his collaborative devices in the car, and travels out of Personal Area Network (PAN) range of the device in the car, the communication system provides for the user to take advantage of the collaborative features the device left behind in the car by bridging the PAN with a WAN via an EVPAN server. Further, the communication system provides for collaborative communication devices to communicate with each other without a need for users of such collaborative communication devices to be authenticated. For example, someone picking up a first communication device of a user can connect to a second, collaborative communication device of the user without the person using the first communication device being authenticated.
