Abstract  Abstract

The present invention relates to a method of transmitting data in a handover between base stations. When a mobile terminal performs a handover between base stations in a wireless communication system a gateway transmits data traffic to be transmitted to a mobile terminal by using an IGMP (Internet Group Management Protocol) to a serving base station being serviced to the mobile terminal and a target base station to which a handover of the mobile terminal is made in a bi-casting method. Accordingly when the mobile terminal performs the handover between the base stations the gateway transmits the data traffic in the bi-casting method. As a result it is possible to efficiently use a resource of a user plane connection interval between the gateway and the base station thereby minimizing the loss of data traffic transmitted in a downlink that is data.
