The invention relates to a communication system (KS) for establishing and clearing connection from and to a cordless mobile part (DECT), in accordance with a cordless message transfer regulation. The cordless mobile part (DECT) can be connected to at least two cordless systems (SLS1, SLS2) as authorised for establishing connection and has a roaming recognition and control logic (RSL) which selects the cordless system (SLS1, SLS2) enabling the best transmission quality from a plurality of cordless systems (SLS1, SLS2) simultaneously recognised as being suitable for establishing a connection. The cordless mobile part (DECT) can also be connected to a mobile cordless system (SLS1) with a mobile base station (BS1) which is provided to convert signals, received or to be sent to the cordless mobile part (DECT), in accordance with the cordless message transfer convention of said part, into signals for a global cellular system. The roaming recognition and control logic (RSL) only allows for stationary cordless systems (SLS2) when selecting a cordless system (SLS1, SLS2) for establishing a connection independent of the transmission quality obtainable using a mobile cordless system (SLS1), in case at least one stationary cordless system (SLS2) is recognised as being suitable for establishing a connection. |
