PROTECTION METHOD AGAINST ANOMALY OF EXTENDED TRUNKING SYSTEM AND A RELAY STATION

摘要

Methods for abnormality protection on an extended trunked radio system and associated repeater stations are provided. A method includes: monitoring, by a present repeater, in real time whether there occurs a communication abnormality on a repeater in a local site; if there is detected a communication abnormality on a repeater, determining whether the abnormal repeater is a free repeater; and if the abnormal repeater is a non-free repeater, updating and broadcasting the state information of the abnormal repeater.
