To keep control of all relevant events in a real-time communication system, there is proposed a load regulation method for a central unit in this real-time communication system such that at least one job is submitted to a job buffer means (18) providing a pre-specified storage capacity. Further, jobs stored in the buffer means (18) are submitted to a processing means (22) for further processing. According to the invention, the available storage capacity of the buffer means (19) is updated dynamically according to the actually used job buffer capacity after each load regulation interval. Thus it is possible, to keep control of all major events and processes within the real-time communication system.
