Abstract

A method and a system for providing a push service in a wireless communication system adopting an Orthogonal Frequency Division Multiplexing (OFDM) scheme or an Orthogonal Frequency Division Multiple Access (OFDMA) scheme are provided. The method includes when receiving a message from another network or another messaging server, transmitting, at a messaging server, a push service request message to a push server; when a Mobile Station (MS) of which the push service is requested using the push service request message of the messaging server, operates in an awake mode, transmitting, at the push server, a first push deliver message comprising a message designated for the MS, to a Base Station (BS), and when receiving the first push deliver message, transmitting, at the BS, a second push deliver message based on a Media Access Control (MAC) layer comprising the message designated for the MS, to the MS.
