The present invention relates to a method for operating a network traffic reduction policy. The method comprises the following steps: checking, by a policy server, the identification information of a policy agent installed on a wireless terminal device corresponding to the identification information of a user wireless terminal device located in an overloaded area using a storage medium which matches the identification information of the wireless terminal device to the identification information of the policy agent included in the wireless terminal device and the matched information stored; transmitting, by the policy server, policy information for blocking network usage to the policy agent corresponding to the checked policy agent identification information; preventing, by the policy agent, all applications excluding the application corresponding to the identification information of a predetermined application allowed to access a network among multiple network usage applications from accessing the network based on the policy information for blocking network usage; transmitting, by the policy server, policy information for unblocking network usage to the policy agent if the policy server receives, from a server in a communication network, more than one piece of the identification information of a user wireless terminal device which leaves the overloaded area and the identification information of a user wireless terminal device which is located in the overloaded area at the moment when the overload is resolved in the overloaded area; and unblocking, by the policy agent, network access for an application based on the received policy information for unblocking network usage.
