  • Patent number: 7821988
    Abstract: A dispatch client device that also has a local wireless transceiver will monitor the energy level on the local transceiver side and use the energy level as a basis to function as a floor control client on a dispatch side. For example, upon receipt of a dispatch-session invitation from a dispatch server, the client may accept the invitation only if the energy level is low enough (indicating that no one is currently talking on the local side) and may then bridge the dispatch communications with the local communications, and otherwise the client may reject the invitation. As another example, if the device detects sufficient energy on the local side (indicating someone on the local side has begun talking), the device may responsively request the floor on the dispatch side and then bridge the local communications with the dispatch communications. The device may apply a standard non-squelch circuit for energy detection.

  • Patent number: 7751833
    Abstract: A system and method for determining the location of a base transceiver station (BTS) are provided. A personal BTS can determine its location using information transmitted by neighboring BTSs or from mobile station transmissions to neighboring BTSs. If the personal BTS cannot determine its location using information from neighboring BTSs or from mobile station transmissions, the personal BTS can contact a cellular network operator to request that a technician come out to verify the location.
