Method for providing service to users through modifying qos profile

Service providing method through the user QoS change of a radio packet service system according to the present invention is a method for a radio packet service system consisting of a SGSN and GGSN in the WCDMA mobile communication network providing wireless packet service between a mobile communication medium with the host, the after analyzing the packets sent to the mobile communication medium from the host based on the analysis (Quality of Service) QoS to the mobile communication medium with the result further comprising: a profile change request; And the mobile communication medium is changed, the user QoS based on the modified QoS profile for transmitting in accordance with said request, the method comprising: providing a service accordingly; and characterized in that it comprises a high bandwidth by checking a user packet received periodically assigning a QoS such as more bandwidth to users with services they need and use network resources efficiently by reallocating a lower QoS than the quality of service (QoS), such as the allocation to users who use the services that require low bandwidth, bandwidth and it is able to provide faster and better wireless packet services to users
