| 1. Overview of Data
Compression Functionality |
| The data compression functionality
will be introduced as a value added feature of PRIN, an
Internet access service, to bring more pleasurable usage
environment to AirH" users. This functionality makes the
Internet communication protocol more efficient and compresses

data files, thereby speeding up the Internet experiences
of users. |
| 2. Description of Data
Compression Function |
| The data compression function
includes two enhancements. |
 |
More efficient
communications protocol
Various Internet communications protocols are converted
to a protocol that suits AirH", resulting in more efficient
data communications. |
|
Data compression
The data sent and received is compressed, reducing the
transmission time. |
| These features generate
results as follows: |
| (1) |
Browsing
home pages |
|
Along
with more efficient communications protocol
and downsizing the file size of JPEG
and GIF image data files, the time taken
to display the entire home page can
be reduced drastically.
*Users can configure compression rates
in four levels. |
| (2) |
Sending
and receiving e-mails |
|
Along
with more efficient communications protocol,
and by reducing the file size of data
transmitted, the transmission time is
reduced. |
| (3) |
File
transfers |
|
Along
with more efficient communications protocol,
and by reducing the file size of data
transmitted, the time taken to download
and transfer files is reduced. |
|
|
| Communications protocols
supported |
| HTTP |
- Protocol
for browsing home pages and Web-Mails |
| HTTPS |
- Protocol with secure
encryption added to HTTP |
| POP3 |
- Protocol for receiving
e-mails from the servers that store electronic mails |
| IMAP |

the subject titles and the e-mail sender |
| SMTP |
- Protocol for sending
e-mails to servers, and exchanging e-mails among servers. |
| FTP |
- Protocol for file
transfers (file downloads). |
| * |
The data compression
functionality must be configured individually for each
type of communications protocol. |
| Between dedicated software
installed on the users' PC and the dedicated data compression
server in the PRIN Center, performing more efficient communication
protocol and data compression. |
| Users will not be charged
for the data compression functionality. |
| 5. AirH" Services Supporting
Data Compression |
