Patent ID: 8498392

Claim:
A method for establishing a communication channel ( 17 ) between a predetermined number of selected devices ( 3 ; 5 ) each having its own identity, by pairing via a server ( 1 ), said devices each having a pairing operational mode and a communication operational mode, wherein the method comprises the steps of: setting each of the devices in the pairing operational mode, agreeing on the choice of a pairing signal ( 19 a ; 19 b ), selecting the agreed upon pairing signal ( 19 a ) on each of the devices, which devices transmit their identity and the agreed upon pairing signal ( 19 a ) to the server ( 1 ), repeating the above second and third steps, if the server ( 1 ) in a predetermined time interval in a predetermined time interval determines that more than the predetermined number of selected devices have transmitted the agreed upon pairing signal ( 19 a ; 19 b ), wherein a next pairing signal is agreed upon, until the server ( 1 ) determines that only the predetermined number of selected devices have transmitted an identical sequence of pairing signals ( 19 a ; 19 b ), establishing the communication channel ( 17 ) between the devices by the server ( 1 ), and setting each of the devices in the communication operational mode.
