Abstract
Abstract The invention relates to a method and arrangement for controlling a mobile subscription in a mobile communication system. The invention finds particular utility in arranging prepaid calls and in monitoring a quantitative right of use in a digital mobile communication system. An idea of the invention is to include the information about the accumulated or remaining right of use (ACM) in a response message (SRES′) transmitted to the network in connection with the authentication ( 210 ). Inclusion in the message can be realized using a predetermined algorithm ( 208 ). This way the network is able to check, using the corresponding algorithm, that the charge information stored in the SIM module of the mobile station is correct ( 214, 218 ). In addition, the algorithm stored in the SIM module can be altered by the operator using an SMS (Short Message Service) message system associated with SIM modules.
