Mobile telecommunication subscriber system in a multi-operator environment

Abstract

The invention relates to a system for monitoring mobile telecommunications in a multi-operator environment. The system of the invention comprises at least one user control station (UCS) comprising a home location register (HLR) containing a unique subscription number (USN) and other required subscriber data, and an account control unit (ACU) containing the subscriber's credit information. The home location register (HLR) and the account control unit (ACU) are interconnected in order for the home location register (HLR) to be able to check the credit information of the calling subscribers in response to requests from the network operators and correspondingly to debit the subscribers' accounts on behalf of the operators by the charge of the calls made. The invention is characterized in that the visitor location register (VLR) or the user control station (UCS) can allocate several temporary numbers (TN) to each terminal.
