Description

Asymmetric Subscriber Line Transmission System for Internet Access and Groupware between Subscribers

The present invention relates to an asymmetric digital subscriber line (hereinafter referred to as "ADSL") transmission system, and more particularly to an asymmetric subscriber line transmission system capable of Internet access and groupware between subscribers.

In general, in order to use the Internet service, each subscriber has a unique Internet Protocol (IP) address and accesses the Internet individually through a dedicated line or a telephone line, or multiple subscribers are connected to a local area network (LAN). It connects to the Internet through a network server connected by LAN.

However, in the former case, all subscribers must have their own unique IP addresses, and groupware between subscribers is impossible. In the latter case, groupware is possible through LAN between subscribers, Similarly, each subscriber must have a unique IP address, which is also expensive. In addition, neither of these methods makes full use of the true server and client concepts.

Therefore, there has been a demand for a system that allows a large number of subscribers to access the Internet efficiently with fewer IP addresses and also enables groupware between subscribers. Based on the high-speed information transmission capability, Internet service, video-on-demand service and If the above system is configured using the ADSL transmission system having the characteristics of providing other multimedia services, the effect is expected to be great.

As described above, the conventional Internet access method has a problem that it is expensive to have a unique IP address for each subscriber and to connect a separate network such as a LAN for groupware between each subscriber.

Accordingly, an object of the present invention is to provide a system that allows a plurality of subscribers to use the Internet service using a small IP address.

It is another object of the present invention to provide a system that enables groupware between subscribers without connecting a separate network between subscribers.

Referring to FIG. 1, an Internet service provider 100 represents a service provider that supplies a service program in an existing Internet service. The internet network 102 is a network provided by an internet service provider for internet service. The mother station apparatus 104 of the ADSL transmission system includes a subscriber modem 110 and a network server 106, and the subscriber modem 110 has a plurality of subscriber station marks connected to the subscriber line 122 through the subscriber line 122. The signals transmitted in connection with the devices 112, 114, 116 are converted from analog to digital or digital to analog. The network server 106 refers to, for example, a workstation or the like provided in the mother station apparatus 104 of the ADSL transmission system according to an embodiment of the present invention, and the external internet network 102 through the digital line 122. Connected to the subscriber terminals 118, 120 and 122 through the subscriber modem 110 to read and record the corresponding information according to the information transmission request and the information storage request from the subscriber terminals 118, 120 and 122 from its own hard disk 108. Or it collects from the Internet network 102 and transmits back to the subscriber terminals (118, 120, 122). The hard disk 108 is a large-capacity storage medium that is shared by each of the subscriber terminals 118, 120, and 122 to enable groupware between subscribers. The local station 112, 114, 116 of the ADSL transmission system is connected to a subscriber telephone (not shown) and subscriber terminals 118, 120, 122 on the subscriber side, and has a modem (not shown) similarly to the mother station 104. The signal transmitted through the subscriber line 122 is converted from analog to digital or digital to analog. Subscriber terminals (118, 120, 122) has a simple input / output means to minimize the cost, refers to a terminal device for mounting a network card for communication with the network server 106.
