Description

Method and device for controlling communication between terminal and branch processor

The present invention relates to an interface of a communication network, and more particularly, a terminal and a branch for wirelessly connecting a financial terminal device to a branch processor (BP) and wirelessly transmitting and processing data generated from the terminal device to the branch processor. It relates to a communication control method and apparatus between processors.

In general, financial institutions such as banks install a host computer that performs a central computing function in a main office, and a terminal device as a data input / output device at a window of each branch, and connects the whole body or a telephone line therebetween. Afterwards, an on-line task of processing data generated by the terminal device is performed.

Here, a branch processor is provided between the host computer of the bank headquarters and a terminal device such as an ATM (Automatic Teller Machine), a CD (Cash Dispensor) installed in branches of various regions, and the branch processor provides a host processor. Up to 16 communication lines are provided, including those connected to computers. Accordingly, one branch processor can control terminal devices at up to 15 points.

As described above, a series of financial computer networks including a host computer for providing real-time demand data from a plurality of terminal devices connected to a branch processor, on the other hand, form a communication network such as interconnecting communication cables at a long distance. Data can be transferred. In other words, when connecting a host computer on a LAN with a long-distance network, it is possible to establish a single host computer that can be used exclusively on the LAN, and to connect with the long-distance network via this dedicated host computer at low cost. You can build a communication network.

By using such a dedicated host computer, an interface with a long distance network can be easily implemented, and even when connected to multiple long distance networks, the number of host computers is set to provide a service.

1 is a schematic configuration diagram showing a network in which a terminal device is generally connected to a bank's host computer and processes data. Referring to this in more detail, a plurality of terminal devices 14a, 14b, 16a, Branch processors 14 and 16 for managing 16b) and respective management programs corresponding to the branch processors 14 and 16 for managing the branch processors 14 and 16, and the corresponding branch processors 14 and 16 to manage the branch processors 14 and 16, respectively. 16, a branch processor management operating system 12 that manages and operates a host computer 10, a host computer 10 for detecting and transmitting request data generated from the terminal devices 14a, 14b, 16a, and 16b to the terminal device, and also TCP. It is composed of a router 18 for connecting the other computer 20 and the branch processor 22 to the bank computer network 10, which is connected to / IP, Ethernet and is capable of short-range or long-distance communication connection.

In the network configured as described above, request processing generated from a specific terminal device will be described as follows.

First, any terminal device operator operates the specific terminal device to be used to connect to the branch processors 14, 16 and 22. When the connection is made, the branch processor 14, 16, 22 notifies the operator of the available state of the terminal device with a response signal indicating that the connection is made.

Thereafter, a communication path is established between each other, and the operator can remotely control the host computer of the bank computer network 10 through the terminal device according to the control operation of the branch processors 14, 16, and 22.

When the connection between the branch processors 14, 16, and 22 via the host computer and any terminal device is completed, the host computer detects a request input from the terminal device and provides a request response to the corresponding data to the operator through the terminal device. do.

All online operations are performed through sequential protocol processing from the connection of any terminal device to the branch processor 14, 16, 22 until the request generation and response processing of data are made.

Here, the branch processor 22 connected to the bank computer network 10 through the TCP / IP and Ethernet networks, and the router 18 for connecting and connecting the other computer networks 20 to each other using a relay function in the network network are used. As a device for interconnecting communication networks, speed conversion function providing communication functions to computers and terminal devices of different speeds, protocol conversion function for converting data such as connection of lines and various control functions, and conversion between different character codes Various functions such as performing a function may be provided to enable communication between different devices.

In other words, a data request is generated from the branch processor, and the online work performed after the terminal device is connected to the branch processor is performed after connecting the terminal device and the host computer to a communication line and transmitting and processing the data to the host computer at the same time as the data is generated. The result is output from the host computer to the terminal of the data generation point. At this time, the data input to the terminal is transmitted while being controlled by the communication protocol procedure between the host computer and the branch processor.

However, according to the above-mentioned conventional technology, a plurality of terminal devices are connected to the branch processor to perform online work with the bank computer network. The communication line is configured by wire from the host computer to the terminal device used directly by the operator. In the event of a failure, it was cumbersome to perform a test on the communication line.

The testing of the faulty communication line may include disconnecting the faulty line in a physical manner, reconnecting it, and restarting the branch processor after shutting down the branch processor.

First, when the circuit is physically disconnected, it is difficult for the branch processor to check the state of the line at the point where the failure occurred, so it is impossible to verify if the cause of the line failure occurs at the point itself. Do.

In addition, a method of shutting off the branch processor, which is the second method, may occur when the communication line between different points in normal operation is taken offline.

In other words, the method for cutting the above-described obstacle line has a problem that the online operation of the bank is paralyzed by cutting not only the fault line but also the line in normal operation.

Accordingly, the present invention excludes the provision of a service by a wired communication line between a branch processor and a terminal period in the above-described conventional technology, and performs a communication interface between a branch processor and a wireless terminal device. The present invention provides a method and apparatus for controlling a communication between a terminal processor and a branch processor for implementing a wireless communication interface by providing a gateway for identifying a point number, an index number, and an index of a terminal device and establishing a mutual communication path. There is a purpose.

In another aspect of the present invention, the purpose of performing mutual communication between the gateway and the terminal device is to enable wireless transmission / reception of data by an interface of a radio terminal control protocol (RTCP).

In still another aspect of the present invention, in the event of a communication line failure between the branch processor and the terminal period, the trouble of having to test the line is eliminated, thereby eliminating the problem of paralyzing online work, Its purpose is to facilitate mutual communication.

The data communication control process between the wireless terminal and the branch processor by the communication control device configured as described above is as follows.

Here, in describing the operation of the present invention, the description thereof may be omitted in the same parts as in the prior art.

First, when a connection request with the branch processor 106 is generated from any wireless terminal device, the request data is transmitted to the gateway 104 via the wireless data communication device 102 (ST140).

Data wireless transmission / reception between the wireless terminal device and the wireless data communication device 102 is performed in units of 12.5K through 160 transmission channels by a radio data link access protocol (RD-LAP) method.

Subsequently, data is transmitted to the gateway 104 through the transmission channel, and the gateway 104 checks whether a connection is made to the wireless terminal that requires the connection to the branch processor 106 among the received data and then determines whether to connect. . That is, after performing a function of code conversion or protocol conversion through mapping process of bank branch number, wireless terminal number value and terminal distinguished value among received data, wireless terminal and branch where connection request is generated. A communication path with the processor 106 is set (ST142) (ST144).

In addition, data is transmitted / received by a Radio Terminal Control (RTC) protocol, which is an interface specification using the standard context routing (SCR) protocol to enable communication with the wireless terminal and the gateway 104.

That is, the gateway 104 is a device for connecting a general local area network with a public network, and provides a protocol conversion function to provide both different networks, for example, a service that cannot be provided in two different networks, for example, a LAN. It is used when

In addition, the gateway 104 connects to the branch processor 106 using four existing TCP ports, whereas the gateway 104 connects to the wireless terminal device 100 or the wireless data communication device 102 using one TCP port.

The terminal discrimination value, the point number, and the radio terminal number value included in such data are confirmed by the index / point / number verification unit 120. In addition, in order to transmit the data transmission by the wireless protocol to the branch processor 106, it is necessary to change the different connection method, etc., so that the port conversion processing unit 122 performs port conversion (ST146).
