Abstract: System, devices and method for authentication are disclosed. The system includes a first device having data stored therein and a second device adapted to receive an authentication request signal. The authentication request signal is associated with the first device. The second device is further adapted to transmit an authentication signal in response to the authentication request signal. The first device and the second device are adapted to be carried by a user, and the authentication request signal and the authentication signal are wireless signals.

Abstract: The techniques described include a method and system for allowing applications which require or work better with different virtual machines to be successfully installed on a device in such a way that different applications may be executed in different virtual machines. The method comprises identifying an application and based on the identification, identifying the virtual machine which is best suited to execute the application. The application is installed such that the application is executed in the identified virtual machine when the application is launched.

Abstract: The invention relates to a method, a telecommunications system, a message server and terminal equipment enabling that the sender of a message can be billed for a reply to the message. In the method of the invention, an indication is added to a first message, indicating that the sender of the first message is billed for a reply to the first message, the message containing the first indication is transmitted (506) to the receiver, and when the receiver replies to the message, a second indication is added to the reply of the receiver, containing at least a part of the first indication, and on the basis of the second indication, the sender of the first message is billed (516) for the reply.

Abstract: Method and system for processing charge messages in a telecommunication system comprising a registering point for distinguishing received charge messages from each other, a first telephone exchange connected to a calling subscriber and a second telephone exchange connected to a called subscriber, said telephone exchange using charge calculation based on charge messages of the originating and terminating side, a charge message being sent during call set-up from the originating side to the registering point. A charge message received from the terminating side is checked; the charge data or the originating side and terminating side are combined if they bear similarities; the charge message is modified to from a replacing charge message that contains the combined charge data; and the replacing charge message is sent to the registering point.

Abstract: Method and system for presenting the price of a telecommunication connection on the telecommunication terminal of the committer of the telecommunication connection in a telecommunication system comprising a telephone exchange, a telecommunication terminal communicating with the telephone exchange via a telecommunication network and a billing center which takes care of charge calculation in the network and is connected to the telephone exchange. According to the invention, connection-specific advice-of-charge data is transmitted to the telecommunication terminal at the beginning of the telecommunication connection, using the telecommunication terminal, a price for the telecommunication connection is calculated from the advice-of-charge data; and the calculated price of the telecommunication connection is presented on the telecommunication terminal.
