Abstract: The invention relates to a method performed by a network node of managing online charging, and a network node performing the method. In an aspect of the invention, a method performed by a network node of managing online charging of sponsored data connectivity is provided. The method comprises receiving (S101) a user request for service related to the sponsored data connectivity, estimating (S102) a number of users that are expected to use said service, and acquiring (S103), from an Online Charging System authorizing access to the sponsored data connectivity, authorisation for the estimated number of users that are expected to use said service.

Abstract: A communication bus (B1, B2, Bp) in a motor vehicle (110) transfers electrical signals between the nodes (N1, N2, N3, Nn, N21, N2m, Np1, Npr) included in the motor vehicle. The communication bus comprises two unshielded signal lines (S1, S2) and a decoupling line (D), which are configured so as to divert undesired electromagnetic radiation deriving both from external systems that are not connected to the communication bus (B1, B2, Bp) and the electrical signals transferred via the unshielded signal lines (S1, S2). The decoupling line (D) is connected for alternating current to a ground potential in one and only one (N3) of the nodes (N1, N2, N3, Nn, N21, N2m, Np1, Npr) included in the communication system.

Abstract: With the intention of simplifying the manner in which a loudspeaker is mounted on a circuit board while maintaining requisite sealing and damping between the loudspeaker and the circuit board, the loudspeaker is affixed directly to the circuit board (1) by means of a double-side adhesive annulus (3) with the diaphragm of the loudspeaker facing towards the board, wherein the board has holes (4) located opposite the loudspeaker. The number of holes (4) provided and the size of the holes may be adapted to provide the best sound production in accordance with application. When a loudspeaker is mounted in this way, all components can be collected on the circuit board and therewith simplify manufacture of the telephone apparatus as such, irrespective of whether the circuit board is in the handset or some other part of the apparatus.
