<p>A mobile communication network system comprises a mobile communication network (MNW); a plurality of external networks (EX1-EX3); a plurality of mobile terminals (x, y, z); a plurality of gateways (EGW1-EGW3) connecting the external networks (EX1-EX3) to the communication network (MNW); and a plurality of radio access points (APa1-APc2) connecting the mobile terminals (x, y, z) to the mobile communication network (MNW). When packets are sent and received among the mobile terminals (x, y, z) in the mobile communication network (MNW), communication is performed via virtual networks provided to the mobile communication network (MNW), one for each of the external networks (EX1-EX3), not via the external networks (EX1-EX3).</p> |
