PURPOSE: A method for dynamic policy interworking between PCRF(Policy and Charging Rules Function) and NAT(Network Address Translation) and an apparatus thereof is provided to process a resource subscription request from a service that uses a public IP address, using a NAT, when allocating a private IP address to a user equipment due to the deficiency of an IPv4 address. CONSTITUTION: A PCRF includes a MODEM(710), a controller(720), a storage unit(730), and a service information manager(740). The modem is a module for communicating with other devices. The controller controls general operation of the PCRF. The storage unit performs a function for storing a program for controlling general operation of the PCRF and temporary data generated during program execution. If it is a PUSH mode, the service information manager sends a subscription information request to a NAT. If receiving mapping information from the NAT, the service information manager sends the NAT an acknowledgement of acknowledging that the PCRF has received the mapping information from the NAT.
