Patent ID: 8094549

Claim:
A device for classifying a quality of service (QoS) for a packet in a portable Internet system, the device comprising: a packet classification unit for classifying the packet into a first packet corresponding to at least one transport connection identifier (CID) and a second packet that is not corresponding to at least one transport CID by using at least one established packet classification rule; a QoS information storage unit for storing a plurality of pairs of application program name and QoS parameter information of the respective application program; a program search unit for searching the application program name of the second packet from a plurality of application programs by using header information of the second packet; a QoS information management unit for obtaining QoS parameter information of the second packet from the data stored in the QoS information storage unit by using the application program name searched by the program search unit; a packet classifier rule generation unit for generating a new packet classification rule by using the header information of the second packet, and a CID management unit for changing at least one transport CID or generating a new transport CID by combining the new packet classification rule and the QoS parameter information.
