Abstract:
1. An apparatus for processing a packet data of a wideband wireless local loop (W-WLL) system comprising: a local area network (LAN) controller for performing an interface with a LAN and transmitting and receiving the packet data; a high-level data link control (HDLC) controller for transmitting and receiving the packet data to and from a subscriber wireless connection unit through a HDLC channel; a memory for separately storing data transmitted between the HDLC controller and the LAN controller, wherein the memory includes a plurality of buffers for separately storing packet data inputted from the LAN controller, the plurality of buffers comprising: a processor for controlling the memory, the LAN controller and the HDLC controller, and concurrently, performing a function of a packet data routing unit, wherein the apparatus determines that packet data is mobile image data based on a port number within a header of the packet data being a specific number and the apparatus further stores the mobile image data in the first buffer when the packet data is determined to be mobile image data based on the port number within the header being the specific number, and the apparatus stores data in the second buffer when the packet data is determined to not be mobile image data based on the port number within the header of the packet data not being the specific number.
