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

摘要

A method for creating/changing a transport CID in a portable Internet system and a terminal for the same are provided to enable a CID managing unit to confirm whether QoS parameter information, inputted through a user input/output unit, is equal to a service grade of the CID, and then create a new CID or add new packet classification rules to the confirmed CID according to the confirmation result, thereby exactly classifying packets and differentiating a packet service between the terminal and a base station. A terminal comprises the followings: a packet monitoring unit(210); a user input/output unit(230) for receiving QoS(Quality of Service) parameter information from a user with respect to a packet of which classification is impossible; a CID(Connection Identifier) managing unit(250); and a data storage(220). If there is no CID having a service grade equal to a grade of the inputted QoS parameter information, the CID managing unit(250) starts a DSA(Dynamic Service Add) process in order to create a new CID. If there is the CID having the service grade equal to the grade of the QoS parameter information inputted through the user input/output unit(230), the CID managing unit(250) starts a DSC(Dynamic Service Change) process in order to add new packet classifier rules, on the packet of which classification is impossible, to the CID having the same grade.
