Abstract: PURPOSE: A method for applying DS(Differentiated Service) for an asynchronous mobile system and a system thereby are provided to offer DS to a UMTS(Universal Mobile Telecommunication System)/GPRS(General Packet Radio System) network. CONSTITUTION: A GPRS gateway(100) for DS consists of a meter(102), a marker(104), a sharper/dropper(106), and a classifier(110). The meter(102) measures the characteristics of a stream selected by the classifier(110) for a traffic profile specified in a traffic contract and transfers the measured information to the marker(104) and the sharper/dropper(106). The marker(104) marks the DS field of an IP traffic with one DSCP, and adds each packet to a proper DS aggregate. The sharper/dropper(106) consists of a sharper function to delay some or all packets in order to set streams to a traffic file and a dropper function to execute policing. The classifier(110) is composed of a QoS(Quality of Service) mapping and DSCP(DS Code Point) classification function(112), a QoS query function(114), a query interface(116), a PDP(Protocol Data Type) context DB(118), and a QoS cache(119).
