  • Publication number: 20180288599
    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.

  • Patent number: 10070452
    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.

  • Patent number: 9843457
    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.
