Abstract: A method and a system for establishing a local routing in a mobile communication network, and for allowing different mobile stations connected with the same Access Service Network GateWay (ASN GW) to transmit and receive traffic without delivering such traffic to a Home Agent (HA) are provided. In the method, a session server determines whether first and second mobile stations are connected with the same ASN GW by using their location information. In case of a connection with the same ASN GW, the session server establishes a local routing in the ASN GW so that traffic between the first and second mobile stations is directly routed to each other at the ASN GW. Then the ASN GW receiving the traffic from one of both mobile stations transmits the traffic to the other according to the local routing.
