UMTS QoS Training Course Powered by ENO

The UMTS QoS Training course examines how the UMTS network supports end-to-end Quality of Service. The different functions and protocols supporting end-to-end QoS are described, with focus on the UMTS Bearer Service and the solutions in the packet switched domain.

Duration: 2-3 days

Customize It:

• If you are familiar with some aspects of UMTS QoS Training, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the UMTS QoS Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the UMTS QoS Training course in manner understandable to lay audiences.


After completing this UMTS QoS Training course, attendees will be able to:

◾ Understand what Quality of Service to expect from the UMTS network and what requirements this put on the different nodes in the UMTS architecture.
◾ Understand what different solutions that can be used to enable QoS in a packet switched etwork, and the benefits and limitations of each solution.
◾ Understand how end-to-end Quality of Service could be implemented using IP and ATM mechanisms.
◾ The implementation of QoS on each interface in the UMTS architecture is discussed, from the radio interface and ATM network to the IP solutions in the backbone and the External Bearer Service.
◾ The QoS solution of the IP Multimedia Subsystem (IMS) is described
