If the value is zero ("0", null) it contains its own switch identifier, otherwise it is passed upstream.

Subsequently, the ATM terminal register 11 of the indoor communication controller 10 receiving the switch registration 402 cell allocates a new switch identifier, and the integrated management unit 13 manages its own ATM switch 20 and ATM. When a new switch 20 is added to the connection structure of the terminals 30, the communication processor 14 creates a switch registration complete cell 403 including the newly allocated switch identifier in the virtual path identifier field 34 and transmits the cell to the home communication network. do.

Subsequently, the reduced ATM switch 20 receiving the terminal registration 404 cell from its downlink port 22 reports the cell's virtual path identifier field 43 and the value is zero ("0", null). If so, it contains its own switch identifier, otherwise it passes to the upstream port 21 as it is.

Subsequently, the ATM terminal registration unit 11 of the indoor network controller 10 receiving the terminal registration 404 cell allocates a new terminal identifier, and the integrated management unit 13 manages the switch 20 and the ATM terminal that it manages. When the new ATM terminal 30 is added to the connection structure of the 30, the communication processor 14 creates a terminal registration complete 405 cell containing the newly allocated terminal identifier in the virtual channel identifier field 45, and delivers the cell to the home communication network. do. Then, the ATM terminal 30 having received the terminal registration complete 405 cell acquires its own identifier to perform a communication function.

When the reduced ATM switch 20 automatically registers with another reduced ATM switch 20 or the ATM terminal 30 connected to its down port 22, the switch registration is completed (403). In the process of receiving the cell from the upstream port 21 and transmitting the downlink port 22, the identifier of the newly registered switch 20 or the ATM terminal 30 can be known. By creating and maintaining a table containing all the identifiers of the other switch 20 directly or indirectly connected to) and the identifiers of the ATM terminals 30 directly connected to its downlink port 22, In the inter-30 communication, these tables can be used to automatically find the cell's delivery path.

In general, since the reduced ATM switch 20 has about six down ports 22, the size of a table managed by one reduced ATM switch 20 is very small.

When requesting a call setup with a specific remote node using the local network controller 10, ATM signaling by mapping a virtual path identifier / virtual channel identifier (VPI / VCI) pair and a switch identifier / device identifier (SID / DID) pair After performing connection establishment and updating routing information, the call establishment confirmation (Call_Ack) cell is transmitted to the requested ATM terminal 30 so as to transmit desired data. If all data is transmitted and then the connection is to be released, the ATM terminal 30 transmits a call release request (call_req) cell. The indoor network controller 10 receiving this releases the connection through ATM signaling, removes the corresponding routing information, and sends the result to the call release confirmation (Call_Ack) cell.

As shown in FIG. 9, when the indoor 1394 terminal 50 wants to communicate with a remote 1394 terminal, a remote ATM terminal, or a proximity ATM terminal, the signal substitution process of the indoor communication network controller 10 will be described. If you want to send asynchronous traffic between the request to establish a call with a specific remote node according to the IEEE 1394 standard arbitration procedure, the home network controller 10 is a virtual path identifier / virtual channel identifier (VPI / VCI) pair and node number By mapping to perform ATM signaling to establish a connection, update the routing information, and then transmit to the ATM terminal to transmit the desired data. When the asynchronous 1394 traffic is transmitted to the remote place through the ATM access network, the home network controller 10 performs address translation and packet conversion properly. If asynchronous data is transmitted to a neighbor ATM terminal, address translation consists of a mapping between a switch identifier / device identifier (SID / DID) and a node number.

FIG. 10 is a flowchart illustrating a signal processing procedure of an indoor communication network controller when the 1394 terminal processes isochronous data with remote or near-field terminals in a 1394-based home communication network according to the present invention.

As illustrated in FIG. 10, when the indoor 1394 terminal 50 wants to communicate with a remote 1394 terminal, a remote ATM terminal, or a proximity ATM terminal, the signal substitution process of the indoor communication network controller 10 will be described. If you want to transmit isochronous traffic between them, the channel is allocated according to the IEEE 1394 standard channel allocation procedure and multicast ATM signaling is performed between the remote nodes corresponding to this channel so that the 1394 channel and the ATM multicast channel are mapped. Send traffic. When the isochronous 1394 traffic is transmitted remotely through the ATM access network, the premises network controller 10 performs address translation and packet translation appropriately. If isochronous data is transmitted to a nearby ATM terminal, address translation enables multicasting with nearby ATM home network equipment.

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

As described above, the present invention can automatically register ATM-based equipment when an ATM-based home communication network and a 1394-based home communication network coexist and have an effect of automatically detecting a failure or failure. In addition, unlike the other home communication methods developed so far, the present invention communicates by using an ATM switch and an identifier of an ATM, and thus can transmit and receive necessary control information between devices. The scheme of using this identifier is the same as that of the virtual path identifier and the virtual channel identifier used in the asynchronous transmission mode.

In addition, the present invention has an advantage that the ATM-based ATM switch follows the requirements of the asynchronous delivery mode by selecting a cell forwarding path using only the header field without analyzing the information field of the passing cell.

In addition, the present invention is capable of communicating with a 1394-based home communication network, and when communicating with a remote ATM terminal or a 1394 terminal through an ATM access network, an over-the-board according to signaling of other home communication network equipment using a signal substitute function. There is an effect that can communicate while reducing the head.
