METHOD FOR GENERATING/CHANGING TRANSPORT CONNECTION IDENTIFIER IN PORTABLE INTERNET NETWORK AND PORTABLE SUBSCRIBER STATION THEREFOR

摘要

The present invention relates to a method for generating/changing a transport connection identifier (CID) in a portable Internet system, and a terminal using the same. Accordingly, the present invention provides a terminal including a packet detecting unit, a user input/output unit, a CID managing unit, and a data storing unit. The packet detecting unit determines whether a packet can be classified by a pre-established packet classification rule or a packet cannot be classified by the rules. For the packet that cannot be classified by the pre-established packet classification rule, the user input/output unit receives QoS information from a user. The CID managing unit generates a new packet classification rule for the unclassified packet, checks a CID in a data storing unit, the CID having the same QoS class as that of the QoS parameter input through the user input/output unit, and determines whether to generate a new CID or to add the new packet classification rule to the pre-established CID depending on the checking result. The data storing unit stores the new packet classification rule generated by the CID managing unit and information on the CID.
