Patent ID: 6975861

Claim:
Channel entering method for a RF communication system, in particular an indoor network, comprising a plurality of subscriber stations (S 1 to Sn, n 3 2), each of said subscriber stations (S 1 to Sn) having a transmitter and a receiver, whereby information can be exchanged between said subscriber stations (S 1 to Sn) using respective transmitters and receivers and a plurality of channels are available for RF communication in said RF communication system, said method comprising the steps of: a) providing a first set of communication reference parameters (I 1 , M 1 ); b) using said first set of communication reference parameters (I 1 , M 1 ) to test a first group of channels (C 1 to Cm, m 3 2) of said plurality of channels for RF communication between a first and a second subscriber station (Sx, Sy; 1 £ x £ n, 1 £ y £ n) of said plurality of subscriber stations (S 1 to Sn); characterized by the further steps of: c) providing, if for said RF communication between said first and said second subscriber station (Sx, Sy) no channel of said first group of channels (C 1 to Cm) meets said first set of communication reference parameters (I 1 , M 1 ), a second set of communication reference parameters (I 2 , M 2 ); d) using said second set of communication reference parameters (I 2 , M 2 ) to test a second group of channels (C* 1 to C*m, m 3 2) for said RF communication between said first and said second subscriber station (Sx, Sy), wherein said second group of channels (C* 1 to C*m) comprises said first group of channels (C 1 to Cm) at least partially; e) entering one channel (C*x, 1 £ x £ m) of said second group of channels (C* 1 to C*m) tested in step d), if for said RF communication between said first and said second subscriber station (Sx, Sy) said channel (C*x) meets said second set of communication reference parameters (I 2 , M 2 ); wherein RF communication between said first and said second subscriber stations (Sx, Sy) based on said first set of communication reference parameters (I 1 , M 1 ) is of higher quality as compared to RF communication between said first and said second subscriber station (Sx, Sy) based on said second set of communication reference parameters (I 2 , M 2 ).
