Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Before Industrial Use) The present invention relates to a computer system that includes a communication system section separate from the computer main body.

(Prior art) In recent years, computer systems equipped with communication functions have been equipped with a communication system section separate from the computer main body, and this communication system section transmits and receives data, thereby distributing the load on the computer main body and making it more efficient. There are systems that allow data processing. When transmitting data, this type of system transfers the data from the computer to the communication system.
Thereafter, this communication system section uses the hardware and communication program to transmit the transmission data to the communication line. In addition, when an incoming call occurs to the communication system section, the communication system section receives the received data that arrives via the communication line according to the communication program, and after the reception is completed, the received data is transferred to the computer main body. has been done.

By the way, some communication system units are equipped with multiple types of communication programs having different network architectures. When performing data communication by selectively using these communication programs, access has conventionally been performed as follows, for example. That is, as shown in FIG. 4, between the business programs A, B, and C of the computer and the communication programs a, b, and c, the I10 command code specific to the communication program is first exchanged, and the other party's program is communicated with. After accessing and establishing the bus on the computer bus BUS by this access, the above-mentioned specific 110372
1 system was used to send and receive data.

(Problem to be Solved by the Invention) However, in such conventional computer systems, each communication program uses a separate 1103721 system to access the other program, so the access method is fixed. For this reason, even though there are multiple types of communication programs, it is difficult for one business program to freely use these multiple types of communication programs, resulting in a lack of flexibility as a system. There was a problem.

Therefore, the present invention focuses on this point and makes it possible to freely access multiple communication programs with different network architectures using a common access method. The purpose of this invention is to provide a computer system that can dynamically set combinations and construct a flexible network architecture.

[Structure of the Invention] (Means for Solving the Problems) The present invention has a computer main body that executes business processing according to a business program, and a plurality of types of communication programs, and executes communication processing according to these communication programs. In a computer system equipped with a communication system unit, connection management means are provided on the computer main body side and the communication system side, respectively, and when a call request is generated from a business program by a desired communication program, this communication The connection management means on the computer main body side notifies the address parameter representing the communication program to the connection management means on the communication system side, and the connection management means analyzes the content of the address parameter and notifies the corresponding communication program and starts it. and when an incoming call occurs to the communication program, the connection management means on the communication system side notifies the management means on the computer main body side of the address parameters created according to the address system of this communication program. ,
This management means analyzes the contents of the address parameters and notifies and starts the corresponding business program.

(Function) As a result, business programs on the computer side can access any communication program in the communication system section using a common access method, and as a result, business programs of multiple types can be accessed using a common access method. Data communication can be performed by freely selecting and using communication programs.

Therefore, data communication can be performed by dynamically setting the combination of the business program and the communication program of the computer itself, thereby increasing the flexibility of the system.

(Embodiment) FIG. 1 is a schematic configuration diagram of a computer system according to an embodiment of the present invention, where K indicates the computer main body, and Tl and T2 indicate a communication system section, respectively. First of all, the computer main body L (is equipped with a plurality of different business programs A, B, and C. On the other hand, each communication system section Tl, T2 is provided corresponding to a different network architecture, and these The communication program Tla- represents several different subsets of the network architecture of
Tie, T2a-T2c.

By the way, the computer system of this embodiment is provided with a first connection management means NCMI attached to the computer main body K, and further provided with second connection management means NCM21. An NCM 22 is provided for each. 1st
The connection management means NCMI includes address parameter analysis means in addition to resource management for the computer main body, input/output means for the computer bus BUS, memory access means for the computer main body, and the like. This address parameter analysis means includes each business program A in the computer main body,
When the address parameters of the communication program are output from B and C, the address parameters are analyzed and the corresponding second connection management means NCM21. Notify NCM 22 of address parameters representing the subset. In addition, a second connection management means NCM21°NCM
When address information is sent from 22, this address information is analyzed and the corresponding business programs A, B, and C are activated.

On the other hand, the second connection management means NCM21. NCM22 is
In addition to resource management means for the communication system units TI and T2, input/output (Ilo) means for the computer bus BUS, etc., each of them has address information analysis means. This address information analysis means is the first connection management means NCM.
When an address parameter is sent from I, this address parameter is analyzed and the communication program of the corresponding subset is activated. At the same time, when address information is output from the communication program due to an incoming call, this address information is analyzed and the first connection management means N
This is to notify CMI.

With such a configuration, first, in the computer main body K, the business program A makes a transmission request in step 31, as shown in FIG. 3, and creates an address parameter for selecting a desired communication program. Assume that it is output in step 32. Note that 'M2 diagram (a) shows an example of the structure of an address parameter, in which network architecture or protocol identification data id is placed at the beginning, followed by address length data and information representing the address system of the communication program. It is arranged. Then, the connection management means NCMI determines that the call has been made by the business program A due to the arrival of the address parameter, and in step 33 analyzes the address parameter and sends the plurality of second connection management means NCM21. It is determined which connection management means of the NCM 22 should be notified.

As a determination method at this time, for example, all the second connection management means NCM21. The address information may be notified to the NCM 22 using a broadcast method, and the response may be waited for. It is also possible to adopt a learning method in which after performing such an operation, the determination result is stored and used as a reference for the next determination. When the second connection management means to be notified is determined, the first connection management means NCM1, in step 34, sends the communication information of the address parameters to the second connection management means to be notified, for example, NCM21. Transfer the address information necessary to select the program.

In response to this, T? to which address information was sent from the first connection management means NCMI? z2 connection management means NCM21
At step 35, the address information is analyzed to determine which subset of the communication program should be selected;
Step 3 for this communication program, for example, Tla.

As a result, the communication program Tla is activated, and thereafter, in step 37, sends the transmission data transferred from the computer main body K to a communication logical channel (not shown) according to a predetermined protocol. Therefore, the transmission data of the business program A is the communication program T.
transmitted according to la.

Thereafter, in the same way, business program A becomes communication program T.
If an address parameter into which address information of lb or Tlc is inserted is output, the corresponding second connection management means NCM21 is accessed by the first connection management means NCMI according to the contents of this address parameter, and the second connection management means in parentheses is The communication program Tlb or Tic to be used is activated by the means NCM 21 to transmit data. The above access operation is performed in exactly the same way even when other business programs B and C select communication programs T2a to T2c of other network architectures and transmit data.

On the other hand, when an incoming call occurs to any communication program, this communication program first represents a subset of its network architecture in accordance with the address system of the communication program in step 41, as shown in FIG. 4, for example. Address information is assembled and this address information is sent to the corresponding second connection management means N Ctvl in step 42.
Notify 21.

Then, in step 43, the second connection management means NCM21 analyzes the address information, assembles address information representing the network architecture where the call was received, and transfers this address information to the first connection management means NCMI in step 44. Transfer to.

As a result, the first connection management means NCMI performs step 4
At step 5, the address information is analyzed, and the step 46 notifies the corresponding business program. Therefore, the business program is started as shown in step 47, and thereafter the data received by the communication program where the incoming call occurred is transferred to the business program, and predetermined data processing is performed by this business program. It will be done.

The above access operation is performed in the same way when an incoming call occurs in another communication program.

In this embodiment, the first connection management means NC is connected to the computer main body and each communication system unit TI, and to the T2 side.
