Abstract: A method for charging for a service in a telecommunications/data network, in particular UMTS mobile radio network, transactions which relate to debits being transmitted to a debiting system on network elements which implement a debiting interface, by means of an adapted transmission protocol, a hot-billing protocol which supports a termination message of the debiting system being used as the transmission protocol, a network element which is involved in the debiting transaction transmitting a message to the debiting system both at the start and at the end of the service and the service being timed in the debiting system in parallel with the execution of the service and debiting being carried out in response to the measurement result.

Abstract: A method for ascertaining a billing tariff for billing for a data transfer, where a mobile communication terminal which is involved in the data transfer and has access rights for a data mobile radio network is situated in a visitor mobile radio network. The method involves setup of a data tunnel, used for transferring the data, prompting transfer of an item of location information which relates to the communication terminal from a switching center, temporarily associated with the communication terminal, in the visitor mobile radio network to the network gateway node in the data mobile radio network. The network gateway node transfers the item of location information to a billing system, and the billing system uses the item of location information to establish that the communication terminal is situated in the visitor mobile radio network. Thereupon and the billing system ascertains a billing tariff which is associated with the visitor mobile radio network.

Abstract: A method for ascertaining a billing tariff for billing for a packet switched data transfer, where a mobile communication terminal which is involved in the data transfer and has access rights for a data mobile radio network is situated in a visitor mobile radio network. The method involves a data link being set up between a billing system, which performs billing for the data transfer, and a central subscriber register in the data mobile radio network, and this data link being used to transfer to the billing system an item of location information which relates to the current location of the communication terminal. The billing system uses the item of location information to establish that the communication terminal is situated in the visitor mobile radio network, and the billing system ascertains a billing tariff which is associated with the visitor mobile radio network.

Abstract: The invention relates to a method and a pricing system for ascertaining total price data in a mobile-radio-assisted ordering process. In this context, following transmission of order data, performed using a mobile radio network, from an ordering communication terminal to a provider communication terminal associated with a service provider, a pricing system is supplied with ordering data, associated with the order data, by the provider communication terminal. The pricing system uses network use data, which are transmitted by the mobile radio network and appear in connection with the ordering process, to select from a volume of price-influencing data stored in an influence memory the price-influencing data which are associated with the ordering process, and the ordering data and the read price-influencing data are used to ascertain the total price data concerning the ordering process.

Abstract: A system and method for accessing protected datasets or other resources in an IP network or on a content server using a mobile radio terminal over a mobile radio network, where in response to an access attempt, an authorization list stored in an authentication database is accessed in order to perform an authorization check on the basis of an identifier, particularly of the call number, over an intelligent network linked to the mobile radio network, and access is enabled or blocked on the basis of the result of the check.
