Display for charging information for mobile station supporting unstructured supplementary service data

摘要

The mobile station (MS) has a service arrangement for performing services, a dialogue device for unstructured supplementary service data (USSD) for setting up a communications channel to the network and the display. The display receives charge information in the form of USSD messages via the dialogue device; it receives USSD messages for the start of a service, terminates the communications by acknowledging receipt of charge information, computes the costs and displays them to the user. Independent claims are also included for a mobile station, a digital cellular communications network and a method of generating the charging information.
