The method, device and medium according to the invention provide forward compatibility to higher devicemedium versions. The user equipment is served in a cell controlled by the radio base station, and which radio base station and user equipment are comprised in the radio communications network. Different elements within a message, such as textual content and graphical content elements, can be scaled independently using magnification factors optimized for each element. The system includes a SNOOZE state that allows the ignition switch to be temporarily turned off during a trip and the alert to be stopped by pressing a snooze switch. Upon rotation of the union member, the length andor phase angle between the first and second coupling members changes. Within the proxy, the request can be redirected from the downstream component to a simulation component according to a routing rule within the proxy using a processor.
