| 7. A data flow control method of a mobile terminal that includes an Rm interface unit for communication with a high speed
communication device and a Um interface unit for communication with a wireless network to perform reverse communication from
the high speed communication device to the wireless network, the method comprising:
receiving data from the high speed communication device and buffering the received data in the Rm interface unit in a byte
stream format;
paging an Operating System (OS) device driver in response to an interrupt signal from the Rm interface unit, reading data
buffered in the Rm interface unit, and storing the read data in a first packet buffer queue in the OS device driver;
de-linking an address of the data stored in the first packet buffer queue from a first linked list for managing the first
packet buffer queue, and linking an address of the de-linked data to a second linked list for managing a second packet buffer
queue included in the Um interface unit, to deliver the data from the first packet buffer queue to the second packet buffer
queue; and
converting data stored in the second packet buffer queue into a frame format, and transmitting the frame-format data from
the Um interface unit to the wireless network.
