The present invention relates to a virtual communication module and a method for verifying a communication protocol using the same. More particularly, when developing a communication protocol performed on a communication system, a virtual communication simulation implemented in software even in a communication environment without hardware is provided. As a method of pre-implementing and verifying a communication protocol through a model, a virtual communication protocol is provided that enables a user to develop and verify a communication system through simulation by providing a software communication module that can be used when a user develops a communication protocol in a one-to-one communication environment. It relates to a communication module and a communication protocol verification method using the same.

With the wave of informatization and the increased integration of systems and the rapid development of related technologies, users are also demanding more convenient communication systems. Therefore, there is a demand for various systems using computer networks and wireless communication networks as well as communication systems using wired and wireless telephone networks, and various types of service contents, such as voice, video, graphics, and data, can be individually or simultaneously. It is provided. As a result, communication protocols used in communication systems have also been diversified, ranging from simple protocols to multiplexed and complex protocols.

On the other hand, in developing a communication protocol, the development period is lengthened by developing in a state where all communication related hardware is prepared in a state where only basic implementation is completed, and it is developed while operating directly on the hardware. There was a difficulty. In addition, this process requires much effort and work to create a simulation environment for the basic implementation because the characteristics of the communication protocol are performed while exchanging information with the counterpart terminal in real time.

Figure 1 schematically shows a hardware-based communication protocol development environment according to the prior art.

As illustrated, in order to perform the communication protocols 100 and 130, device drivers 110 and 140 and modems 120 and 150, which are actual system environments, are required. Wired and wireless communication itself is a task performed in a hardware environment, which is performed by the modem (120, 150). The device drivers 110 and 140 serve to control the modems 120 and 150 which are hardware, so that the protocol 100 and 130 programs which are software. For communication, both sides are composed of the same environment, and video, audio, data, and control signals used in the communication system are transmitted to the modem through the device driver under protocol management, and finally, the related data is transmitted and received from the modem. However, the development and verification of the communication protocols 100 and 130 in the actual hardware development environment is accompanied by a considerable difficulty in the characteristics of the hardware, the debugging environment is not good, there is a problem that the development period is long.

In order to solve the above problems, an object of the present invention is to provide a software-based virtual communication module environment when developing a protocol operating in a communication system, thereby facilitating the development environment and shortening the development period.

As a technical means for solving the above problems, the first aspect of the present invention is a message queue / client of the transmitting side and the receiving side making a request for sending or receiving data, and a transmitting side for sending or receiving data in response to the request. And a message queue / server on the receiving side, and a network / client on the sending side and a network / server on the receiving side in connection with the message queue.

Preferably, in the virtual communication module, the network is a TCP / IP network.

A second aspect of the present invention provides a method comprising the steps of multiplexing and sending data to a first message queue / server by a first message queue / client, and sending the data to the first network / client by the first message queue / server; The first network / client sending the data over a network to a second network / server, the second network / server sending the data to a second message queue / server, and the second second Message queue / server sends the data to a second message queue / client, and the second message queue / client demultiplexes the data to separate the data. Provide a method.

Preferably, in a communication protocol verification method using a virtual communication module, the network is a TCP / IP network. The data includes video, audio and control signals.

Figure 2 schematically shows a communication protocol development environment using a virtual communication module according to an embodiment of the present invention.

Referring to FIG. 2, the virtual communication module environment makes two virtual communication modules 210 and 230 with software (S / W), and the virtual communication modules 210 and 230 communicate with each other to exchange data. have. When the communication protocols (terminal A, terminal B) 200 and 220 need to exchange data, the virtual protocols 210 and 230 may be called to perform desired tasks.

FIG. 3 schematically illustrates an internal structure of the virtual communication module of FIG. 2.

Referring to FIG. 3, the virtual communication module includes a message queue / client 310 and 350 for making a request for sending or receiving data, a message queue / server 320 and 360 for sending or receiving data in response to the request, and the message queue. And a network / client 330 and a network / server 370 for sending and receiving data through a network in association with the network.

In more detail, the data processing method applied to the virtual communication module of the present invention is a method of communicating with a message queue based on a TCP / IP network. In order to use the virtual communication module, a module implementing the communication protocol (terminal A) 300 includes a message queue / client 310 module for an interface.

The method of using the virtual simulation is to operate a program including the message queue / server 360 module and the network / server 370 module of the other party (terminal B) first and then the message queue / server 320 of its own terminal (terminal A). Operate a program that contains modules and network / client 330 modules. Thereafter, the communication protocol (terminal B) 340 module to which the message queue / client 350 of the other party is interfaced, and the communication protocol (terminal A) to which the message queue / client 310 of its own party are interfaced ( 300) Start the simulation by running the module.

When the simulation starts, the general asynchronous communication system divides various data such as video, audio, and control signals into small units of data that can be transmitted by multiplexing in a protocol module. Each data is sent to the message queue / server 320 in the network / client 330 module via the message queue / client 310 module and the message queue / server 320 in the network / client 330 module. The program sends data to the partner network / server 370 module via the TCP / IP network. The other party's network / server 370 module that receives the data sends data to the message queue / server 360, and the message queue / client 350 in the other party's communication protocol 340 demultiplexes the sent data to display the data. It is processed separately by voice and control signal. This communication step can be performed in the opposite direction (terminal B to terminal A) in the same manner, thereby enabling simultaneous data transmission and processing in both directions.

The network communication method using the message queue used in the virtual communication module is conveniently modularized to be used in most asynchronous communication systems using the communication module.

As described above, when the present invention is applied in developing a communication protocol operating in a communication system, since the bidirectional communication environment is constructed with software, the communication protocol can be developed even without hardware development, and for the verification of the communication protocol. Since there is no need to build a separate verification environment, development can be made relatively easy. Since all development environments are made of software, debugging is easy and development time can be drastically reduced.
