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 (5304). 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 (5322, 5324). The CID managing unit generates a new packet classification rule for the unclassified packet (5326), checks a CDD in a data storing unit (5328), 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 (5340) or to add the new packet classification rule to the pre-established CID (5330) 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 (5354).
