An automatic redialing method for amiable communication network and a mobile communication system are disclosed. When a call meant for a telephone terminal belonging to a public switched telephone network is originated on a mobile station, but the telephone terminal is busy, a mobile communication exchange receives BUSY information from an exchange covering the telephone terminal on a control line. The mobile communication exchange transfers the BUSY information to a base station covering the calling mobile station. The base station transforms the BUSY information to a corresponding BUSY message capable of being sent on a radio channel and sends the BUSY message to the mobile station by adding it to the control field of a reverse control channel. On receiving the BUSY message, the mobile station once disconnects the channel, sets its timer, and redials the telephone terminal on the elapse of a preselected period of time.
