ABSTRACT:
A method of transferring data from a plurality of remote terminals to a central location over a communication network is disclosed. First random numbers are respectively generated for each of the remote terminals. A mask value is then determined. The random numbers associated with the remote terminals are compared with the mask value to determine whether a respective terminal attempts to transfer data to the central location. In a disclosed embodiment the method is used to locate new terminals in a hotel or hospital system.
