Abstract

A method for sending a service by a first gateway (GW) among multiple GWs includes, upon reception of a request for a service from a terminal, determining whether the first GW is able to provide the service, detecting a second GW that is able to provide the service requested by the terminal among the multiple GWs based on GW management information that includes respective service information regarding services that the multiple GWs are able to provide, if the first GW is not able to provide the service, requesting the second GW to provide the service requested by the terminal, and upon reception of the service from the second GW, forwarding the service to the terminal.
