The method includes searching for, by a management server cluster, a first push server corresponding to predetermined search criteria from among a plurality of push servers upon receiving a request to connect with a push server from a mobile terminal; providing, by the management server cluster, connection information regarding the found first push server to the mobile terminal; and delivering, by the first push server, upon generation of a notification event after connecting with the mobile terminal, event information corresponding to the push notification event to the connected mobile terminal. ## Claims ### Claim 1 A push notification system for providing a push notification service, the system comprising: a first server configured to receive a push notification from a push notification providing server; and a second server configured to deliver the push notification to an electronic device based on receiving the push notification from the first server, wherein, based on a request from the electronic device to register for the push notification service with the push notification system, registration information for providing the push notification service is received and forwarded to the push notification providing server by the electronic device. ### Claim 2 (depends on 1) The push notification system of claim 1, wherein the second server is further configured to establish a connection session with the electronic device. ### Claim 3 (depends on 2) The push notification system of claim 2, wherein the second server is further configured to establish the connection session with the electronic device based on the registration information. ### Claim 4 (depends on 3) The push notification system of claim 3, wherein the second server is further configured to transmit the push notification to the electronic device using the connection session. ### Claim 5 (depends on 2) The push notification system of claim 2, wherein the second server is further configured to transmit the push notification to the electronic device using the connection session. ### Claim 6 A push notification system for providing a push notification service, the system comprising: a first server configured to receive a push notification from a push notification providing server; and a second server configured to deliver the push notification to an electronic device based on receiving the push notification from the first server, wherein, based on a request from the electronic device to register for the push notification service with the push notification system using the first server and the second server, registration information for providing the push notification service is received by the electronic device and forwarded to the push notification providing server by the electronic device, and wherein the registration information comprises information for enabling the push notification providing server to transmit the push notification to the electronic device. ### Claim 7 (depends on 6) The push notification system of claim 6, wherein the registration information comprises connection information for providing the push notification service. ### Claim 8 (depends on 7) The push notification system of claim 7, wherein the connection information comprises an address of the second server. ### Claim 9 (depends on 6) The push notification system of claim 6, wherein second server is configured to establish a connection session with the electronic device. ### Claim 10 (depends on 9) The push notification system of claim 9, wherein the second server is configured to transmit the push notification to the electronic device using the connection session. ### Claim 11 (depends on 6) The push notification system of claim 6, wherein the push notification providing server is an app server. ### Claim 12 A method of a push notification system providing a push notification service, the method comprising: receiving, by a first server, a push notification from a push notification providing server; delivering, by a second server, the push notification to an electronic device based on receiving the push notification from the first server; and based on a request from the electronic device to register for the push notification service with the push notification system using the first server and the second server, receiving registration information for providing the push notification service by the electronic device, and forwarding the registration information to the push notification providing server by the electronic device, and wherein the registration information comprises information for enabling the push notification providing server to transmit the push notification to the electronic device. ### Claim 13 (depends on 12) The method of claim 12, wherein the registration information comprises connection information for providing the push notification service. ### Claim 14 (depends on 13) The method of claim 13, wherein the connection information comprises an address of the second server. ### Claim 15 (depends on 12) The method of claim 12, wherein second server is configured to establish a connection session with the electronic device. ### Claim 16 (depends on 15) The method of claim 15, wherein the second server is configured to transmit the push notification to the electronic device using the connection session. ### Claim 17 (depends on 12) The method of claim 12, wherein the push notification providing server is an app server.
