Abstract

PURPOSE: A call processing simulation device in a control station system and a method thereof are provided to enable a user to directly set a call process and messages related to communication standards, so as to generate and store a message used under GUI(Graphic User Interface), add or delete each message, or generate an optional message. CONSTITUTION: A message editor(10) generates a new call processing message, stores the generated message in a file, reads and corrects the stored message, and outputs a parameter value for a selected message of messages transceived upon call processing simulation. A message header editor(20) interworks with each unit to generate a structure and a field of a new message header, corrects a structure and a field of a pre-produced message header, and outputs a field value of a message header of a message transceived upon call processing simulation. A call process editor(30) transceives data, arranges sub systems in a control station, selects a message and a message header to be used, and selects a link with a sub system to generate a call process. A call generator(40) generates a message header and a link of a message for transmitting the call process produced in the call process editor(30) to a main simulator(40) using the second queue, and generates all messages received or transmitted by the simulator(40). The main simulator(50) reads the message generated by the call generator(40) from the second queue for delivery to each corresponding link, and first reads a message to be transmitted for delivery to corresponding links if messages to be transmitted and received are accumulated on the second queue. And link parts receive messages from the main simulator(50) for delivery to drivers, and deliver messages received from the drivers to the main simulator(50) through the third queue.

Hereinafter, preferred embodiments of the "call processing simulation apparatus and method in a control station system" of the present invention according to the above technical concept will be described in detail with reference to the accompanying drawings.

First, the simulator according to the present invention takes the role of the base station and the terminal for the network components of the control station, and thus the base station simulator generates a message for the control station call processing test of each mobile communication system.

This system is interworked with the control station system, and the detailed configuration of the simulator is as shown in FIG. 1.

1 is a view showing the internal configuration of the simulator according to the present invention, Figure 2 is a diagram briefly showing the processing of the call processing editor according to FIG.

As shown in FIG. 1, a message editor 10 performs a function of creating, modifying, and editing a call processing message. In this case, the message generation generates a new message, writes each parameter in the generated message, and then sets a default value of each parameter value. When the setting is completed, the prepared message is stored in a file.

In addition, the message modification reads a message prepared in advance and stored in a file, modifies a reference value of each parameter value in the message, and modifies and adds / deletes a parameter in the read message. After the modification and addition / deletion are completed, the modified message is stored in a file.

In addition, the message editing outputs or modifies parameters and parameter values for pre-written messages, and outputs parameter values for selected messages among messages transmitted / received in a call processing simulation.

Next, the message header editor 20 performs a function of generating, modifying, and editing a message header to be used in conjunction with each system. In this case, the message header generation generates a structure and fields of a new message header, sets a reference value of each field, and stores the created message header in a file.

In addition, the message header modification modifies the structure and fields of the pre-written message header, modifies the reference value of each field, and stores the modified message header in a file.

In addition, the message header edit outputs or modifies a field and a field value for a pre-written message header, and outputs a field value for a selected message header among messages transmitted / received in a call processing simulation.

Next, the call process editor 30 generates a call processing procedure using a pre-written message and a message header, and performs a function of modifying and editing the call processing procedure.

That is, as shown in FIG. 2, the subsystems in the control station are listed, the message and message header to be used in conjunction with each subsystem are selected, and then any link to the subsystem is to be connected. Then determine the call processing procedure.

The values of each message or header can be set if you see them in the message editor. In the call processing simulation progress, a main simulator 50, which will be described later, transmits each processing message to the first queue Queue-1, and the call processing editor 30 displays the message processed in the first queue. Read and output, and save the call processing simulation procedure and results in a file. It also modifies or re-simulates the prestored call processing procedure.

Next, the call generator 40 generates a message, a message header, and a link to be used in the call processing procedure created by the call processing editor 30 to use a second queue (Queue-2). It performs a function to deliver to the main simulator 50 to be described later. In addition, the simulator performs a function of generating all messages received or transmitted.

Next, the main simulator 50 reads the message generated by the call generator 40 from the second queue and delivers the message to each corresponding link. If the message to be transmitted and the message to be received are accumulated in the second queue, the message to be transmitted is first read, transmitted to the corresponding link, and the message received from the third queue (Queue-3) to be received in the second queue. Check if the message is delivered to the first queue. If a message different from the message to be received in the second queue is received from the third queue, the message is transmitted in the form of an unknown message to the first queue, and the message is waited for to be received from the third queue.

Next, the ATM link 60 receives the message from the main simulator 50 and transmits the message to the ATM driver, and transmits the message received from the ATM driver through the third queue to the main simulator 50. ) Function.

Next, the Ethernet link 70 receives the message from the main simulator 50, transmits the message to the Ethernet driver, and transmits the message. The message received from the Ethernet driver is transferred through the third queue to the main simulator 50. It performs the function of passing on.

Next, the E1 link 80 receives the message from the main simulator 50 and transmits the message to the E1 driver, and transmits the message received from the E1 driver to the main simulator through a third queue.

3 is a diagram illustrating a message delivery process when a call processing proceeds according to the present invention, and illustrates a process of the main simulator 50 delivering a message according to a call processing progress procedure.

As shown in FIG. 2, when the message to be transmitted and the message to be received are stacked in the second queue, the message A1-H1 to be transmitted is loaded first, and then the link state of the loaded message is checked. Link) and the first queue. Next, the message A2-H1 received from the third queue Queue-3 is loaded to check whether it matches the message A2-H1 to be received in the second queue, and the message is queued only when the message matches. To pass on. If the message received from the third queue does not match the message to be received from the second queue, after transmitting an unknown message (Unknown Message) to the first queue, and waits for a message to be received from the third queue.

According to the present invention "call processing simulation apparatus and method in the control station system" described above, it is possible to simulate all the communication standards currently used in the mobile communication system with one simulator according to the present invention.

In addition, since the user can directly write or select a message, a message header, a connection method, etc., it is easy to create a new communication standard as well as the existing communication standard.
