Abstract: 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 communications 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 Signaling System No. 7 (SS7) network components.

The service does not require modification or updating of the existing network infrastructure, or additional functionality for the infrastructure elements. Subscribers, upon their arrival at a new place, need not call relatives or send short SMS. The service is of particular value to the disabled.

Abstract: The invention relates to methods and system for providing additional services to the subscribers of a mobile cellular communication network, in particular to methods and systems providing travelling subscribers with a service of monitoring, according to their wish, their movement amongst the coverage areas of the mobile cellular communication networks and informing third persons about said movements. The inventive method and system for carrying out said method make it possible to provide the travelling subscribers of the mobile cellular communication networks (MCC) with a service for monitoring their movements between the MCC networks of GSM and UMTS standards, or between the segments of said networks and for informing the recipients selected by the subscriber or another authorised person about the arrival of the subscriber at a new place.
