Abstract
Method and a system for establishing a communication channel between a first communication device, or alternatively, a communication network operator, and one or more second communication devices. The identity of the one or more second communication devices is not pre-determined by the first communication device (or the communication network operator). Instead, the identity of which one or more of the second communication devices connects to the first communication device (or the network operator) is determined by the operation of one or more filters transmitted by the first communication device (or the network operator) on certain data that are both transmitted by the first communication device (or the network operator) as well as measured locally at each of the second communication devices.
