Description

NO.7 MTP TRACE METHOD IN MOBILE COMMUNICATION SYSTEM

The present invention relates to a NO.7 MTP (hereinafter referred to as " MTP ") trace method in a mobile communication system. More specifically, the present invention relates to an MMC (Man) without setting hardware. Machine Communication (hereinafter referred to as " MMC "). The present invention relates to a NO.7 MTP trace method in a mobile communication system that enables monitoring of NO.7 signals between specific power stations using only instructions.

As is well known, in the mobile communication system, when a local station interoperates with another station system and wants to monitor error detection and processing in the process of processing NO.7 signal, a print statement is inserted between user blocks. In order to perform a signal trace, monitoring is frequently performed on a corresponding port. In particular, the above-described monitoring process is essential in the initial system setup process.

At this time, there are three conventional methods for monitoring the signal flow between each system. The first method is a port (Trunk) through the equipment (Turbo-7) for monitoring the NO.7 signal. This is a method of connecting and detecting a port. However, this method can monitor all the signals between the actual home country and the other country system, but the purchase price of equipment is hundreds of millions of dollars, and there is a problem that only a message to a specific large signal point cannot be monitored. In addition, since the first method described above monitors by connecting to a specific signal link, all messages passing through the corresponding signal link are detected by the equipment. However, when there are many messages, the operator must check the signaling point of all messages. As well as inconvenience, there was a problem that the number of signal links that can be monitored according to the capacity of the equipment is limited.

In addition, the second method for monitoring the signal flow between systems in the related art is to perform a signal trace on each block in the local system, and this method needs to know the signal ID (Identification) of the signals to be monitored. If you are not a developer in the field, it is difficult to grasp the meaning of each message, and this method also has a problem that it is impossible to trace specific signal points like the first method described above.

On the other hand, the third method for monitoring the signal flow between the conventional systems is to use the Print statement in the User block, and although the user can trace specific data for each part to be detected, In addition to causing performance degradation, the developer had to insert a print statement for each part, which was inconvenient.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a NO in a mobile communication system to enable an operator to more easily perform a NO.7 signal trace operation between specific powers. .7 provide the MTP trace method.

In addition, the NO.7 MTP trace method in the mobile communication system of the present invention is a signal flow monitoring method using an MTP trace instruction between an operator terminal, a NO.7 data processing block, and an MTP message processing block. Transmitting the input MTP trace command (START-MTP-TRC) to the NO.7 data processing block;

The NO.7 data processing block receives the MTP trace command (START-MTP-TRC) from the operator terminal and transmits a message trace request signal (MtpTrace_Start) for the corresponding signal point of the corresponding station to the MTP message processing block. The 200th step;

Transmitting, by the MTP message processing block, a message trace response signal (MtpTrace_Start_ACK) for the corresponding signal point and all messages (MtpTrace_RP_M2D) transmitted / received to the corresponding power point to the NO.7 data processing block;

After the NO.7 data processing block receives the message trace response signal (MtpTrace_Start_ACK) for the corresponding signal point from the MTP message processing block, all messages transmitted / received to / from the corresponding power according to the result of the response signal (MtpTrace_Start_ACK). Step 400 of receiving (MtpTrace_RP_M2D);

A step (500) of the NO.7 data processing block decoding all messages (MtpTrace_RP_M2D) transmitted / received to the corresponding power for each service type and transmitting the result data for the MTP trace to the operator terminal; And

In step 600, the operator terminal receives MTP trace result data for each service type from the NO.7 data processing block and displays the same to the operator.
