The large-capacity communication processing system enables subscribers connected to various subscriber networks to use various services through connection with an information provider (IP) on a service providing network, and provides a chargeback agency function for using such information.

There are two types of user information in the Packet Network Access System (PNAS), which provides a packet switched data communication network (PSDN) access function among various service providing networks of a large capacity communication processing system.

One of them is a user call connected to another subscriber network matching device in a high capacity communication processing system, such as a telephone network (PSTN) subscriber or an integrated information network (ISDN) subscriber, through a high-speed switch module of the high capacity communication processing system. The type of information that a connection is established and sent and received over that connection.

In addition, a packet type subscriber call directly connected to a packet matching device through a packet network is information of a type in which a connection is established in the packet matching device and transmitted through the connection.

Therefore, the packet matching device should be able to process these two types of user information efficiently. In the present invention, a method for performing the user information via the switch module and the user information directly connected to the packet network in the packet matching device is described. I would like to suggest.

A main control board 210 (PSPA: Packet Service Processing board Assembly) for controlling four PNIAs and calculating service control and billing information of subscribers is duplexed and connected to the PNIA and serial (S-BUS) 230.

The high speed network access board 240 (HSNA: High Speed Network Access) that interfaces with the high speed switch device manages two PSPAs and is connected to the VME bus 250.

Information is transmitted and received to the HSNA 240-PSPA 210-PNIA 200 for the first path service 140, and the information transmission path for the second path service 141 is PNIA 200-PSPA 210. ) -PNIA (200).

3A and 3B are diagrams illustrating the configuration of a driving device for processing user information via the subscriber network matching device of FIG.

As shown in the figure, FIG. 3A is an exemplary configuration diagram of a high speed network access board driving apparatus for an interface with a switch module, and FIG. 3B is an exemplary configuration diagram of a driving apparatus of a packet network interface board.

As shown in FIG. 3A, information transmission from the PSPA 210 to the switch module is performed by a transmission task (HsnaTxTask) 301, and all messages are delivered through one transmission queue (HsnaTxQ) 300.

The reception of the information to the PSPA 210 is transmitted through the reception queue (HsnaRxQ) 303 set by the reception task (HsnaRxTask) 302 to the logical channel number (hlun) of each HSNA 240 after receiving the information.

These receive queues 303 are created by the daemon task when the first incoming call comes in.

As shown in FIG. 3B, a message transmitted from the PSPA 210 to the PNIA 200 is processed by an operating system (OS) of the PNIA 200 through a function call.

In response to the packet call connection request of the PSPA 210, the PNIA 200 recognizes this via the mailbox 320, allocates a logical channel number (plun) of the PNIA 200, and sends a message from the PNIA 200. Reception is via the PNIA's logical channel number (plun) per message receipt queue (PniaRxQ) 321.

The information transmission and reception between the PSPA 210 and the PNIA 200 is performed by serial communication, and the operating system (OS) of the PSPA 210 and the PNIA 200 performs this serial communication between the processors (IPC: Inter Processor Communication). Provide by using the function. The main IPC messages between the PSPA 210 and the PNIA 200 include a packet call connection request message (PNIConnReq) 322, a packet data transmission request message (PNISendData) 323, and a packet call release request message (PNIClrReq) 324. ), A response message (PNIConnRes) 325 for the call connection request of the PSPA 210, a message for transmitting the data received from the packet network to the PSPA 210 (PNIRecvData) 326, and a call release request received from the packet network. There is a message (PNIClrInd) 326 for delivery to the PSPA 210.

4 is an exemplary configuration diagram of a driving device for processing user information directly connected to the packet network matching device of FIG. 2.

As shown in the figure, the task of the PSPA 210 is largely composed of a daemon task waiting for an input call and a task generated when a call is input.

The input waiting task 400, which is a daemon task, always waits for input of a new call from the input call receive queue 401. When a new subscriber call is posted to the incoming call receive queue 401, the incoming waiting task 400 generates a channel task 402 to verify the subscriber information.

The channel task 402 generates a task 403 for relaying user packets, a user packet reception queue 404, a task 405 for relaying information provider (IP) packets, and an information provider packet reception queue 406. Send and receive messages.

Message relay tasks (403, 405) is destroyed when the connection with the information provider (IP) is released and informs the channel task 402 through the event flag (407). And, when all the services for one subscriber are terminated, the channel task 402 is also destroyed.

The connection is then established (504) by sending a call setup success response to the subscriber network matching device (505).

When the connection between the subscriber and the information provider (IP) is established, the user message and the information provider (IP) message are queued in the queue (506).

Thereafter, when the user message is received in the message waiting state 506, it is determined whether the received user message is general data or a call release request (507). If the user message is general data, the data packet Data_Packet is transmitted to the information provider (IP). Transmit (508) and wait (506) in the message receive queue again. If the received user message is a call release request, after transmitting a call release request (Clear_Request) message to the information provider (509) and receiving a call release confirmation (Clear_Confirm) message from the information provider (IP) ( In step 510, a call release confirmation response is transmitted to the subscriber network matching device (511), and the allocated high speed network access board logical channel number (hlun) and the logical channel number (plun) for packet network matching are released (512).

Meanwhile, when the information provider message is received in the message waiting state 506, it is determined whether the message received from the information provider (IP) is general data or a call release indication message (513). It transmits to the network matching device (520) and waits again in the message receiving queue (506).

If a clear_indication message is received from the information provider (IP), the clear_confirm message is transmitted to the information provider (IP) (515) and a call release request message is transmitted to the subscriber network matching device. After receiving the call release acknowledgment message from the subscriber network matching device (515) (516), the allocated high speed network access board logical channel number (hlun) and the logical channel number (plun) for packet network matching is released (517). ).
