1. A network system comprising:
a first and second radio base station apparatuses which are connectable with a mobile station apparatus; a first network which accommodates the first and second radio base station apparatuses; a first offload apparatus which relays packet data transmitted between the first radio base station apparatus and the first network, and transmits to a second network a portion of packet data transmitted from the first radio base station apparatus after rewriting a first address of the mobile station apparatus with a second address, or transmits to the first radio base station apparatus packet data received from the second network after rewriting the second address with the first address; and a second offload apparatus, wherein the first offload apparatus includes a first control unit which transmits the second address to the second offload apparatus intervened between the second radio base station apparatus and the first network, when the mobile station apparatus changes over connection from the first radio base station apparatus to the second radio base station apparatus, and the second offload apparatus includes a second control unit which receives the second address.
