A push service gateway apparatus for a first push service is provided according to one embodiment of the present invention. The push service gateway apparatus comprises a transceiving unit which sets a tunnel with a different push service gateway apparatus for a second push service that is different from the first push service; and a control unit which checks whether a receiving terminal which received the message is a subscriber to the first push service if a message from a sending terminal is received through the transceiving unit, and sends a query request to the different push service gateway apparatus through the transceiving unit to query about whether the receiving terminal subscribes to the different second push service if the receiving terminal is not the subscriber. If the receiving terminal subscribes to the second push service, the transceiving unit can transfer the message to the different push service gateway apparatus through the set tunnel. |
