Abstract: PURPOSE: A method for controlling QoS(Quality of Service) in a mobile system is provided to improve the total system traffic load and service satisfaction by controlling QoS based on subscriber location information in order in case that a plurality of users demand various QoSs. CONSTITUTION: If a packet call request message is received from a mobile terminal with a QoS request(501), a packet exchange compares the requested QoS(QoS_requested) with the mobile subscriber's QoS(QoS_Subscribed) registered in an HLR(Home Location Register)(502). In case that the requested QoS(QoS_requested) is smaller than the registered QoS(QoS_Subscribed), the packet exchange keeps the requested QoS. If the requested QoS is larger than the registered QoS, the packet exchange replaces the requested QoS with the registered QoS(503). Then the packet exchange obtains a QoS limit value(QoS_RA(Routing Area)) from a location-QoS table and compares the requested QoS with the QoS limit value(504). If the requested QoS is smaller than the QoS limit value, the packet exchange allocates traffic resources according to the value of the requested QoS(506). In case that the requested QoS is larger than the QoS limit value, the packet exchange replaces the requested QoS with the QoS limit value(505) and executes resource allocation according to the replaced value(506).
