<p>According to the illustrated embodiment, the authentication of a cellular network customer in a LAN hotspot area is made possible by a Sign-up server (SUP). The customer enters his cellular phone number (MSISDN) and the SUP contacts the cellular network's HLR via GGSN to get customer identification information (MSIN). SUP creates an account in the system of the LAN network. The generated account details are sent to the users' cellular terminal, e.g. by SMS or e-mail. The usage of LAN services is calculated and the resulting billing information, CDR:s including the MSIN ID, is sent to the cellular network billing system and the customer gets billed by their cellular network operator .</p> |
