Abstract: Disclosed are a system for providing a push service using a feedback message including: a service providing device to transmit a push message to a client device and receive a feedback message with respect to the transmitted push message; and a push service device to receive the push message from the service providing device and transmit the push message to the client device, store the feedback message when the push message transmitted to the client device fails and a connection with the service providing device is disconnected, and transmit the stored feedback message to the service providing device.

Abstract: Disclosed are a system for providing a push service including: a client device to receive a push message provided by a service providing device and provide a push service; and a push service device configured to transmit the push message provided by the service providing device to the client device, wherein at least one of the client device and the push service device is configured to attempt a reconnection mutually according to a predetermined reference, when a connection between the client device and the push service device is terminated.

Abstract: A push service device for balancing message loads includes: a service provider (SP) interworking unit to connect with a service providing device; a controller to route a push message received from the service providing device through the SP interworking unit to one or more corresponding client devices; and a client interworking unit to transmit the push message transferred from the controller to the one or more corresponding client devices, to receive a keep-alive message from at least one of the one or more corresponding client devices, and to transmit a keep-alive configuration message to the one or more corresponding client devices to disperse reception time points of the keep-alive message for a predetermined transmission period of the keep-alive message when the reception time points of the received keep-alive message are synchronized.
