Verfahren und Gerät zum Überwachen eine möglicherweise gegateten (geschalteten) Signals in einem drahtlosen Nachrichtenübertragungssystem

摘要

A remote station, comprises an empty frame detector (220) that detects when a frame is empty and sends a signal indicating such. A counter counts a number of consecutive empty frames. A control processor (222) coupled to the empty frame detector and the counter resets the counter when a good or bad frame is detected. When a number of consecutive empty frames exceeds a threshold, the control processor sends a signal indicating such. A message generator (228), coupled to the control processor, generates a message requiring a reply from a base station when it receives the signal and a transmitter (232) transmits the message.
