The invention relates to a method and a system for processing access service requests in data processing systems, such as telephone exchanges. In the method, only a predetermined number of access service requests are allowed for service simultaneously, and the remaining access service requests are placed in incoming order into an access buffer (21, 31, 41) to wait for service. The invention is characterized in that when a new access service request arrives in the access buffer (21, 31, 41), one or more access service requests which have waited the longest time in the queue are rejected from the access buffer, if the estimated sum of queueing and processing times of the access service requests assessed according to the calculated average processing time of access service requests exceeds a predetermined limit value.
