<p>The invention relates to methods and systems for conducting distributed transactions. The method comprises collecting and transmitting information, setting up a USSD session with a user of a mobile device, and using safe communication channels. The collection of information is performed from information-containing components or GSM/UMTS mobile cellular communication networks or LBS systems of GSM/UMTS mobile cellular communication operators or a GPS system or Wi-Fi positioning systems or combinations thereof. The transmission of information is performed by sending an SMS message to a user's mobile device in the transaction mode via Signalling System No. 7 (SS7) network components. The structure comprises an interface unit, which is connected to the transaction system, an information unit, which is connected to the interface unit and is designed to collect information, an SMS unit, which is connected to the interface unit and to the SS7 network components, and a USSD unit, which has a connection to the interface unit and to the SS7 network components. The setting-up of the USSD session is performed via SS7 network components with a user of a mobile device which is registered in either a home or a visited GSM/UMTS mobile cellular communication network.</p> |
