Abstract: |
As the all-IP based transport network will be used in the second phase of the third generation mobile system (3G),IP Quality of service (QoS) is an important issue for the 3G. Based on the discussion of the QoS archirecture and requirements of the user services in IP-based 3G, the emphasis is laid on the QoS control and implementation of the differentiated services. Some valuable conclusions are also presented. |
