Abstract: The present invention provides a method of protecting the integrity of messages sent between a mobile terminal and a server radio access network controller in a mobile radio system, in which method a message sent is protected by a code calculated on sending and, in the event of a change of server radio access network controller from a source controller to a target controller, a message sent to the mobile terminal by the source controller, for forwarding to the mobile terminal information created in the target controller and then transferred by the target controller to the source controller, is protected by a code calculated in the target controller.
