  • Patent number: 7751810
    Abstract: A system and method of transmitting multimedia data related to an event to the wireless communication units of the event attendees. The multimedia data may be broadcasted on a plurality of channels. For example, multimedia data generated from different cameras across the event venue may be placed on multiple channels. Attendees using mobile communication units may tune to any channel in order to view the event performances from the perspective of the selected camera. Also disclosed is a method of provisioning a mobile communication unit for receiving wireless communication services at an event. In this regard, a user purchases or rents a mobile communication unit containing a unique identifier residing in a radio frequency identification (RFID) tag. The user also purchases for receiving wireless communication services for a particular event. A provisioning device at the event venue reads the identifier from the RFID tag to provision the mobile communication unit for receiving wireless communication services.

  • Patent number: 7738899
    Abstract: Systems and methods of supporting groups that include non-communication address objects are provided. The non-communication address objects can be, for example, items on a shopping list or items on a task list. An application server can receive an unstructured list of non-communication address objects and generate a structured list.

  • Patent number: 7729246
    Abstract: Systems and methods for communications between networks that support dispatch communication services are provided. A server is coupled to at least two networks that provide dispatch communications, one of which employs an inactivity timer. When the server determines that the inactivity timer for a dispatch call is about to expire due to, for example, no bearer packets being transmitted, the server will request the floor of the call. The server will then transmit bearer packets for a predetermined amount of time, and then release the floor.

  • Patent number: 7684817
    Abstract: A wireless communication system including dispatch call controllers, signaling gateways, base stations, a first network coupling the dispatch call controllers to the signaling gateways, and a second network coupling the signaling gateways to the base stations. The signaling gateways serve as intermediaries between dispatch call controllers and base stations by translating messages received from dispatch call controllers intended for the base stations from the protocol used in the first communications network to the protocol used in the second communications network, and translating messages received from base stations intended for dispatch call controllers from the protocol used in the second communications network to the protocol used in the first communications network. The system may be configured such that each dispatch call controller has individual logical links to each of the signaling gateways, and each signaling gateway has logical links to a distinct subset of the base stations.
