Abstract

Up to now it is not possible to find out the MSISDN (Mobile Subscriber Integrated Service Digital Network) of a mobile station, from the mobile station itself. The solution can be realized by an USSD (Unstructured Supplementary Service Data) application in the core network and a SMS (Short Message Service) application in the network. The subscriber keys in an USSD string, which is relayed to the HLR (Home Location Register). The HLR relays this USSD request to the USSD server containing the „Own Number Display" application. This USSD server can be the HLR itself. The MSISDN of the subscriber is relayed back to the mobile station as the response to the USSD request.
