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.

Abstract: A flow control apparatus for a mobile communication system includes a traffic type recognition module which interfaces with an upper layer and determines a traffic type of data from the upper layer, a flow control module which controls flow of the data based on the traffic type determined by the traffic type recognition module, and a lower layer interface module which allows the flow control apparatus to communicate the data with an AAL5 Adaptation Layer. The traffic type recognition module delivers the data to the flow control module when the traffic type of the data is a loss sensitive type and directly transfer the data to the AAL5 when the traffic type of the data is a real time sensitive type. Also, a sliding window control algorithm may be used to control the transmission/reception of data based on, for example, a voice-data ratio.
