A first synchronization signal having a multitude of second synchronization signals, which are removed from a set of second synchronization signals that is subdivided into code sets, is transmitted by a transmitter to a receiver. The JVM, or a garbage collector operating therein, can estimate, for an area of the memory space, the sum of the pause times for garbage collection of the software objects within the area, and control the garbage collection process so that the sum of the pause times for garbage collection will be lower than a target pause time limit, with a high degree of probability. The system includes a device policy repository, a policy decision point, a decision policy enforcer, and an active policy enforcer.
