Network matching devices interworking with subscribers include ADSL network matching devices and Ethernet matching devices. Network matching devices interworking with information providers include the Internet and ATM networks.

FIG. 2 illustrates an interface communication module of an IWU for providing various communication services of an interworking gateway to a user connected to an ADSL subscriber network.

The ADSL network matching device of IWU sets and releases virtual path (VP) / virtual channel (VC) by ATM UNI 3.1 signaling. The inter-network access unit (IWU) includes an ATM line interface module 21 for interfacing with an ADSL subscriber network, an ATM line interface module 22 for interfacing with an ATM network, and a service process for controlling and processing services. Service Processing (SP) module 23 is included. The service processing module 23 includes functions such as virtual path (VP), virtual channel (VC) connection and disconnection, PCI-bus communication function, subscriber information transmission, reception, initialization and self-diagnosis, and service processing in charge of service processing and control. A board 232 and an Ethernet line interface board 231 for receiving an Ethernet subscriber. The service processing board 232 is connected to the ATM line interface modules 21 and 22 through the PCI bus. The service processing board 232 may serve as a bus requestor / coordinator and read / write a 32/16 / 8-bit data transfer bus slave as a data transfer bus (DTB) master. The service processing board 232 is an interrupt processing unit that handles interrupts required by the ATM line interface module through the PCI bus. The service processing board 232 uses two channels for data transmission with another redundant service processing board.

3A-3D are flow diagrams of a multilink call processing in accordance with the present invention.

When the originating subscriber attempts to access the multilink PPP call (301), the ADSL transmits a call setup signal to the interworking device (IWU) (302). Subsequently, the interworking gateway (IWU) task of the interworking gateway transmits a call progress signal to the ADSL in the idle state 303 (304), and the interworking interface (IWU) transmits the call connection signal to the ADSL (305). In step 306, a connection response signal is received from the ADSL.

After collecting the calling number by ATM UNI 3.1 signaling (307), setting the channel link control protocol configuration (308) (308), and after confirming the subscriber's telephone number through the authentication protocol processing (309), The bundle indication signal is transmitted to the ADSL from the manganese connection device (IWU) (310). In operation 311, multilink negotiation is performed through Internet Protocol Control Protocol (IPCP) negotiation.

Next, when the ADSL subscriber attempts to connect to the second channel call (312), sets the second channel link control protocol configuration (313), and finds the bundled channel through the authentication protocol process and checks the subscriber number (314). ). After transmitting the bundle indication signal and the link control protocol option to the ADSL from the network interworking device (IWU) (315), the multilink channel information is reported to the service processing board (316).

After the multilink connection, the ADSL subscriber performs Internet search and file transmission and reception using dial-up networking and a web browser (317). Call termination is initiated by the originating subscriber sending a multilink PPP call termination message to the interworking interface (IWU) (318). When an ADSL subscriber sends a No. 1 B channel link control protocol (LCP) termination request to an IWU via a broadband matching device (319), the IWU sends a link control protocol (LCP) to the ADSL subscriber. In step 320, an end response is transmitted. The IWU sends a VP / VC channel release packet to the broadband matching device (321). The broadband matching device releases the corresponding VP / VC channel, sends a release confirmation (322), and executes channel 1 call release (323). When the ADSL subscriber sends a request for terminating the second channel link control protocol (LCP) to the IWU (324), the ADSL subscriber transmits a second channel link control protocol termination response to the ADSL subscriber (IWU) ( 325). The interworking interface (IWU) sends a VP / VC channel release packet to the broadband matching device (326). The broadband matching device releases the corresponding VP / VC channel, sends a release confirmation and removes the bundle channel at the same time (327), and then executes channel 2 call release (328). After the call is terminated through this process (329), all the tasks transition to the idle state.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.
