Inventive embodiments relate to a method and apparatus for packet transmission control and packet charge data generation on wired/wireless network, especially, the apparatus can control the packet transmission and measure the amount of packet. The apparatus receives a packet data through a network and stores the packet data in a shared memory. After determining whether the packet data satisfies with a filtering rule, it deletes the packet data if the packet data satisfies with the filtering rule and transmits the packet data to destination otherwise. Then, it generates preliminary billing data corresponding to the packet data and transmits the preliminary billing data to a billing apparatus.
