ABSTRACT:
The present invention relates to a wireless mobile communication system, and more particularly, to a method of transmitting data to mobile terminals in the wireless mobile communication system capable of transmitting multicast data.In order to solve the aforementioned problems in the prior art, a method of transmitting data to mobile terminals in a mobile terminal communicating with a network through which multicast data are transmitted. The method of the present invention comprises the steps of transmitting a requesting frame to the network for requesting the multicast data when the start of a multicast service is recognized through an upper layer of the mobile terminal; receiving a response frame from the network in response to the request frame; and receiving the multicast data from the network.
