Abstract:
1. A data flow control apparatus of a mobile terminal that performs reverse communication from a high speed communication device to a wireless network, the apparatus comprising: an Rm interface unit for receiving data from the high speed communication device and buffering the received data in a byte stream format; an Operating System (OS) device driver including a first packet buffer queue for reading and storing data buffered in the Rm interface unit upon receipt of an interrupt signal from the Rm interface unit, wherein the OS device driver manages a first linked list for managing data stored in the first packet buffer queue; a Um interface unit including a second packet buffer queue having the same buffer structure as that of the first packet buffer queue, wherein the Um interface unit manages a second linked list for managing data stored in the second packet buffer queue, converts the data stored in the second packet buffer queue into a frame format, and transmits the frame-format data to the wireless network; a packet processor for de-linking an address of the data stored in the first packet buffer queue from the first linked list, and linking an address of the de-linked data to the second linked list, to deliver the data from the first packet buffer queue to the second packet buffer queue; and a controller for controlling data flow of the first packet buffer queue.
