Quality of service mechanisms and priority management in HSPA system

3G mobile broadband evolution offers high speed data transfer. A need to develop QoS mechanisms to ensure effective handling of radio resources occures. Bottleneck for 3G data network may be located in different parts of the network, depending on the infrastructure (eg the radio access part or core network part). Operators will decide how to deal with network congestion problem: expanding the network, increasing CAPEX or finding and using ways to control traffic.
