METHOD, APPARATUS AND COMPUTER PROGRAM FOR UPDATING A PRIORITIZATION LEVEL OF A SERVICE DATA FLOW BASED ON TRAFFIC SIZE PER TIME UNIT OF SAID DATA FLOW

摘要

This disclosure relates to a method, and an arrangement ( 108, 50, 606, 708) and a computer program for updating a prioritization level of a service data flow between a user node ( 102, 602, 702, 802, 902) and a network node ( 106, 604, 706, 804, 906). The method comprises obtaining (202) a traffic size per time unit of detected data packets of the service data flow, and updating (204, 616, 716, 812, 914) the prioritization level of the service data flow, based on the obtained traffic size per time unit. It is an advantage that embodiments provide a possibility to determine a trade-off between the need to optimize response times for short-lived data sessions and limiting the impact on other users when prioritizing long-lived high volume sessions. It is advantageous that the embodiments are applicable to situations in which a direct classification, using IP 5 -tuple or deep packet inspection is not meaningful.
