Abstract: A method controls the electrical power consumption of a rail vehicle fleet. The vehicle fleet contains a plurality of rail vehicles each having an electrical energy storage system for supplying a drive system. The energy storage systems are charged by an electrical supply network and/or electric charging stations along a rail network. Static and time-varying information of rail vehicles which are currently in a driving mode and static information relating to a timetable, schedule and/or vehicle deployment plan of the currently operated rail vehicles are combined. By the combined information and taking into account the power consumption of the rail vehicle fleet from a charging planning facility, a vehicle-specific charging plan for charging the energy storage systems of the rail vehicles currently in the driving mode is determined. The charging of the energy storage systems of the rail vehicles is carried out in dependence on the vehicle-specific charging plan.

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: Method for authenticating a user for the purposes of establishing a connection from a mobile terminal to a WLAN network A user in a telecommunications network wishes do use a WLAN access. To do this he needs a WLAN authentication token, a login and a password. The key point of the invention is that, for the transmission and communication of the authentication data to the WLAN, it is not the SMS protocol which is used but the alternative USSD (Unstructured Supplementary Service Data) protocol. These so-called USSD strings can be easily entered by users on their terminal keypads. The USSD string is then not sent to the SMS gateway, as in the known method, but is sent directly to the Home Location Register (HLR) of the mobile radio network.
