Course Number        LS 126 103
Course Duration      2 days
Course Description   The 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.
Course Objectives    Upon completion of this training, the participants will be able to
                     successfully describe the UMTS QoS elements and having used
                     them, know what to expect when the QoS features are employed
                     in UMTS networks.

                     Upon completion of this course, the participant will:

                             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 network, 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

Target Audience      This course is beneficial for Telecom professionals who require an
                     understanding of the QoS mechanisms in the UMTS system.

Prerequisites        General knowledge of the UMTS system is recommended.
