A low-traffic service is a delay-sensitive service with a small amount of data. For example, the PING command, belonging to the BE service, is a low-traffic service. When such a service is carried on the HSPA channel, the NodeB cannot identifies the service from the BE services through the service priority and ensure its low delay.
The UMTS network is a radio network whose radio resources are shared by all the UEs in a cell. When the traffic volume in a cell is high, the QoS of low traffic services is easily impacted by other services. Generally, UEs, however, are more sensitive to the delay of burst low traffic services. For example, when the traffic volume in a cell is high, UE must take more time to open a Web page. Therefore, the user experience decreases obviously. This feature identifies a burst service based on the traffic features, and then reallocates much higher bandwidth to it. Thus, a larger bandwidth is available for the data
transmission of the low traffic service, and the UE obtains better service delay experience.
