Automatic redialing method for a mobile communication network and a mobile communication system

A mobile communication system, accommodating a first mobile station on a radio channel and connectable to at least a public network, said system comprising:

• a base station that sets up a radio channel between said base station and said first mobile station;
• and
• a first mobile communication exchange that accommodates said base station to connect calls originating from a mobile station to a desired link including the public network,
• wherein when a call originates from said first mobile station, said first mobile communication exchange sends origination information including a first identification of said first mobile station and a second identification of a called terminal to an exchange that accommodates said called terminal on a control line;
• wherein said exchange that accommodates said called terminal stores, when said called terminal is busy, the first and second identification, monitors a state of said called terminal and sends, upon detecting an end of a busy state of said called terminal, end-of-busyness information including the first and second identifications to said first mobile communication exchange on said control line;
• wherein said first mobile communication exchange includes transferring means for transferring the end-of-busyness information received from said exchange to said base station corresponding to said first mobile station;
• wherein said base station includes message transforming means for transferring, upon receiving said end-of-busyness information from said first mobile communication exchange, said end-of-busyness information to an end-of-busyness message indicating the end of the busy state of said called terminal to be sent to said first mobile station;
• and
• wherein said first mobile station re-dials said called terminal upon receiving said end-of-busyness message from said base station.
