SATELLITE COMMUNICATIONS SYSTEM HAVING USER RF EXPOSURE MONITORING AND CONTROL

摘要

A method and system wherein a system gateway (18) determine if an averaged transmitted power density associated with the antenna of the user terminal will equal or exceed at least one of a predetermined threshold level, within a specified period of time, or an absolute threshold level. If the gateway determines that a threshold will probably be exceeded if the call connection is maintained the gateway terminates the connection. A tone or visual indicator may be employed to warn the user that a current connection or call will be terminated. Provisions are made for allowing predetermined types of calls, e.g. emergency calls, to be made during a cutoff period wherein the user terminal is prohibited from placing further calls.
