1. In a mobile satellite system including a satellite communication switching office having a satellite antenna for receiving/transmitting a satellite message via a satellite from/to a vehicle using a mobile communication system, a central controller receiving/transmitting the satellite message from/to the satellite communication switching office issued from the vehicle via the satellite, a method of providing satellite communication and satellite management for multiple users in a virtual network arrangement, said method comprising the steps of: (a) first and second mobile earth terminals (METs) registering with the mobile satellite system; (b) the first MET selecting a virtual network identifier (VN ID) representing a virtual network group including at least the first and second METs to establish voice communication therewith; (c) the first MET transmitting the VN ID to the central controller; (d) the central controller receiving the VN ID, allocating a frequency for the virtual network group, and broadcasting the message to the virtual network group including the second MET informing the virtual network group of the allocated frequency and the voice communication associated therewith; (e) the second MET tuning to the frequency in response to the message broadcast by the central controller; and (f) the first and second METs communicating with each other on the frequency.
