摘要: In a mobile satellite system, a system for providing satellite communication between multiple users in a closed user group arrangement includes first and second mobile earth terminals (METs) responsively connecter to and registering with the mobile satellite system. The first MET selects a closed user group network identifier (NET. ID) representing a NET group including the first and second METs to establish voice communication therewith and transmits the NET ID to a central controller. The central controller receives the NET ID from the first MET, validates the first MET for communication, validates the NET ID, allocates a frequency for the NET group, and broadcasts the message to the NET group including the second MET informing the NET group of the allocated frequency and the voice communication associated therewith. The second MET tunes to the frequency in response to the message broadcast by the central controller, and the central controller assigns the first MET as current speaker for the NET group.

摘要: In a mobile communication system, a system for providing communication between multiple users in a closed user group arrangement includes, for example, first and second mobile earth terminals (METS) registering with the mobile system. The first MET selects a closed user group network identifier (NET ID) representing a NET group to establish voice communication therewith and transmits the NET ID to a controller. The controller receives the NET ID from the first MET, validates the first MET for communication, validates the NET ID, allocates a frequency for the NET group, and broadcasts the message to the NET group informing the NET group of the allocated frequency. The second MET tunes to the frequency in response to the message broadcast by the central controller. The closed user group arrangement provides security measures to ensure only authorized METs gain access to the NET group, dual standby mode of operation, and/or priority default operation.

The second MET tunes to the frequency in response to the message broadcast by the central controller. A full service dispatch (FSD) system monitors and displays detailed conference activity. The FSD system provides a display conference function that displays all the conference activity usage data; provides a display active conference function that displays updated information in real-time for active conferences; provides a monitor conference function permits selective monitoring of one or more conferences; and provides a monitor user function that permits selective monitoring of one or more users.
