This paper mainly proposes a message push method suitable for iOS mobile terminals. In this method, APNS is used for offline iOS terminal message push and MQTT is used for online iOS terminal message push. This method can reduce the number of messages sent through APNS. It can also solve the disability of storage-and-forward and the dissatisfaction of delivery rate under large amount of concurrent messages or over extent of message length. At the same time, different push strategies can be selected according to the online state of the target terminals. The experimental results about bandwidth and message length show that when the concurrency of pushing messages is large or network resources are insufficient, this strategy can dynamically balance the load or expand the bandwidth of network devices and servers to increase throughput. This strengthens the data processing capability for message push and improve resource utilization.
