Circuit-coupled data services for GSM

When using interactive data services on the packet-based Internet, the data carrier is used only in part of the time. For example, between the data transfers, the user stays to handle and evaluate the information that it has obtained from the database as the carrier is not being used. For some services and users, the circuit-switched and relatively expensive service that GSM offers today is not cost-effective in terms of active utilization. Either the payer uses for the time his communication is silent or it connects up and down the connection according to its needs. The latter is very time consuming because the user must, among other things, authorize each time against their server. The invention solves this by providing a complete digital connection between the mobile device and the current server. The mobile user sets up a session against the server in the usual way by calling and authorizing them by means of solution words and user identity. This session is active until the mobile user interrupts the session by a particular process or alternatively by a time interval unit in cooperation with the system in the form of, for example, a timer (timer) expires. The session will then be superior to a number of connections and disconnections on the GSM
