Abstract In a method of connecting channels of a plurality of decentralized radio systems which perform independent channel connections, each of the plurality of radio systems sets a given channel and monitors a reception signal level of the given channel. Each radio system detects that the given channel is busy and sets a next channel when the reception signal level of the given channel is higher than a level corresponding to a threshold value. Each radio system rejects a connection if all channels are busy. Each radio system detects the given channel as an empty channel and starts communication through the given channel if the reception signal channel is lower than the level corresponding to the threshold value. Each radio system increases the threshold value when the channel connection is rejected. Each radio system decreases the threshold value when the communication is started.
A method of connecting channels of a plurality of decentralized radio systems which perform independent channel connections, comprising the steps of: causing each of the plurality of radio systems to set a given channel and monitor a reception signal level of the given channel; causing said each radio system to detect that said given channel is busy and to set a next channel when the reception signal level of said given channel is higher than a level corresponding to a threshold value; causing said each radio system to reject a connection if all channels are busy; causing said each radio system to detect said given channel as an empty channel and start communication through said given channel if the reception signal channel is lower than the level corresponding to the threshold value; causing said each radio system to increase the threshold value when the channel connection is rejected; and causing said each radio system to decrease the threshold value when the communication is started.

Claim 3
Dependent Claim
34 words
A method as in claim 1, wherein the radio system increases the threshold value by an incrementing amount which is different from a decrementing amount by which the radio system decreases the threshold value.
Claim 4
Dependent Claim
16 words
A method as in claim 2, wherein the incrementing amount is greater than the decrementing amount.
Claim 5
Dependent Claim
17 words
A method as in claim 3, wherein the incrementing amount is about 30 times the decrementing amount.
