Problems solved by technology

[0008] Therefore, existing packet data processing apparatuses have the problem that when a user obtains the information he or she needs and then requests a relatively small amount of data, the request is often delayed due to moving picture packets occupying a buffer

Abstract

A packet data processing apparatus of a wide-band wireless local loop (W-WLL) system includes a local area network (LAN) controller for performing an interface with a LAN and transmitting and receiving a packet data. The system further includes an high-level data link control (HDLC) controller for transmitting and receiving a packet data to and from a subscriber wireless connection unit through an HDLC channel, a dynamic random access memory having a first buffer for storing a mobile image packet data transmitted between the HDLC controller and the LAN controller and a second buffer for storing a packet data other than the mobile image, and a CPU for performing the corresponding control function of a packet data routing unit. Buffers are utilized and managed separately for transmitting mobile image data and general data from the packet data routing unit of the W-WLL system to the Internet.

Description

technical field [0001] The present invention relates to a packet data processing device and method of a broadband wireless local loop (W-WLL) system, in particular to a broadband wireless local loop (W-WLL) system capable of distinguishing and separately processing ordinary packet data and moving image packet data Packet data processing apparatus and method. technical background [0002] Wireless Local Loop (WLL) is a system in the existing Public Switched Telephone Network (PSTN) system in which a certain part between each user terminal and the public line exchange is wireless instead of using wires. WLL is more convenient because WLL telephone network can be installed more easily than existing wired telephone network system. The added convenience of the WLL system is that it is cheaper and the network design is more flexible when users increase and need to be redesigned. [0003] In addition, unlike existing narrowband Code Division Multiple Access (CDMA) networks, wideb...
