METHOD AND DEVICE TO PROVIDE ACCESS TO SERVICES AND EQUIPMENT IN A GSM MOBILE TELEPHONE NETWORK VIA AN EXTERNAL TELECOMMUNICATION NETWORK

摘要

Method and device for providing access to services and equipment in a GSM mobile telephone network via an external telecommunication network, by which an international access switching node (IAN) of a GSM network can be dialled directly, by means of a special call number. Once the international access switching node (IAN) has been dialled, the subscriber is requested to select a desired service or equipment which he/or she wishes to access. Upon selection the subscriber identifies himself/herself through dialogue oriented interrogation of his/her mobile call number (MSISDN) and a personal identification number (PIN). Additional subscriber data can also be queried. A system for automatic call distribution (ACD) with simulation of GSM internal signalling traffic enables a connection to be established with the desired service or equipment by means of the assembled data. Access to the required service or equipment is thus provided once the subscriber's MSISDN or the PIN has been checked.
