Packet data processing apparatus and method of wideband wireless local loop (W-WLL) system

An apparatus for processing packet data of a W-WLL system, the apparatus including a plurality of buffers for storing the packet data, the apparatus comprising:

• a determining device to determine that the packet data includes mobile image packet data when a port number within a header of the packet data is a specific number and determines that the packet data does not include the mobile image packet data when the port number within the header of the packet data is not the specific number;
• a first buffer for storing the mobile image packet data among data transmitted from a local area network (LAN) controller when the determining device determines that the packet data includes mobile image packet data by determining that the port number within the header of the packet data is the specific number;
• and
• a second buffer for storing a packet data other than the mobile image packet data among the data transmitted from the LAN controller when the determining device determines that the packet data does not include the mobile image packet data by determining that the port number within the header of the packet data is not the specific number,
• wherein the first buffer and the second buffer are separately managed for transmitting the mobile image packet data and the other data, respectively, the first buffer and the second buffer being operatively connected between the LAN controller and a high-level data link control (HDLC) controller.

An apparatus for processing a packet data of a W-WLL system comprising:

• a local area network (LAN) controller for performing an interface with an LAN and transmitting and receiving the packet data;
• 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 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 packet data;
• and
• a processor for performing a corresponding control function of a packet data routing unit, wherein the apparatus determines that a received packet data is mobile image packet data and stores the mobile image packet data in the first buffer when the packet data is determined to be mobile image packet data and stores data in the second buffer when the packet data is determined to not be mobile image packet data, wherein the apparatus determines the packet data is mobile image packet data by identifying a port number included within a header of the received packet data as being a specific number, and the apparatus determines the packet data is not mobile image packet data by identifying that the port number included within the header is not the specific number.

A method for processing a packet data of a W-WLL system comprising:

• determining that a received Internet protocol (IP) packet is a transmission control protocol (TCP) packet;
• after determining that the received IP packet is a TCP packet, determining that a port number in a header of the received IP packet corresponds to mobile image data when the received IP packet is determined to be a TCP packet, wherein the determination is based on the port number in the header corresponding to a specific number;
• identifying the mobile image data and other data in the received IP packets, wherein the other data is identified when the port number in the header fails to correspond to the specific number;
• storing the data identified as mobile image data in a first buffer;
• and
• storing the data other than the mobile image data in a second buffer,
• wherein the first buffer and the second buffer are separately managed for transmitting the mobile image data and the other data, respectively, the first buffer and the second buffer being operatively connected between a local area network (LAN) controller and a high-level data link control (HDLC) controller in the W-WLL system.

A method for processing a packet data of a W-WLL system comprising:

• determining that a received Internet protocol (IP) packet is a transmission control protocol (TCP) packet;
• after determining that the received IP packet is a TCP packet, identifying the received IP packet as corresponds to mobile image data when a header of the received IP packet contains a port number corresponding to a specific number, and identifying the received IP packet as corresponding to general data when the header of the received IP packet contains a port number that does not correspond to the specific number;
• storing the received IP packet in a first buffer for processing mobile image data when the received packet is determined to be a TCP packet and the port number corresponds to the specific number identifying mobile image data;
• and
• storing the received IP packet in a second buffer for processing general data when the port number does not correspond to the specific number identifying mobile image data, the general data being non-image data,
• wherein the first buffer and the second buffer are separately managed for transmitting the mobile image data and the general data, respectively, the first buffer and the second buffer being operatively connected between a local area network (LAN) controller and a high-level data link control (HDLC) controller in the W-WLL system.
