The present invention relates to an operation technology for a protocol message in a communication network, and more particularly, to a loss of a protocol message on an interface for interworking between network components for service call processing in a communication network providing a mobile communication service. And a protocol message monitoring system and method for real time analysis and monitoring of errors.

Recently, as the computer, electronic, and communication technologies have developed rapidly, various mobile communication services using a mobile communication network have been provided. Accordingly, mobile communication service subscribers can receive various types of information such as news, weather, sports, securities, exchange rates, and traffic information in various forms such as text, voice, still image, and video through wireless Internet service.

As a result of the development of mobile communication technology, the services provided by the mobile communication system are developing into a multimedia communication service for transmitting not only voice services but also circuit data and packet data.

The mobile communication system has been developed through the first generation analog AMPS (Advanced Mobile Phone System) method and the second generation cellular and personal communication service (PCS) method, and recently established as a standard by ITU-R. IMT-2000 (International Mobile Telecommunication 2000; for example, CDMA 2000 1X, EV-DO, WCDMA, etc.), which is a third generation mobile communication system, is commercially available.

IMT-2000 uses the IS-95C network, which is an evolution of existing IS-95A and IS-95B networks, such as CDMA 2000 1X, EV-DO, and WCDMA. It is a service that can provide wireless Internet at 144Kbps transmission speed much faster than Kbps or 56Kbps. In particular, the IMT-2000 service can improve the existing voice and WAP service quality and provide various multimedia services more efficiently.

Here, the WCDMA method is a mobile communication system implemented asynchronously among the IMT-2000 system. The wireless access method for communication between the base station and the mobile communication terminal adopts the CDMA method, but the technology related to the mobile communication network is GSM (Global System for Mobile communication). Based on network technology. WCDMA method does not need to use Global Positioning System (GPS) to synchronize the entire base station, supports international roaming service, widens the frequency bandwidth to 5MHz and has a data rate of 2Mbps, which is suitable for high-speed data transmission. Diversity is provided according to the reverse call quality, which cannot be provided in the IS-95 and GSM methods, so that the call and data transmission performance is relatively good even in a poor communication environment. However, since the WCDMA scheme does not support backward compatibility with the existing CDMA and GSM schemes, a new mobile communication network must be constructed and a mobile communication terminal supporting the WCDMA scheme should be used.

In addition, as the WCDMA communication network has more network components than the existing synchronous network, there are many interfaces between the network components and the quality of communication service is lost due to the loss or error of messages on the interface. There was a case of degradation or system failure.

In addition, since the WCDMA communication network is in the early stage of providing a mobile communication service, the number of subscriber attempts is not high. Therefore, the analysis and monitoring of the communication rate and the completion rate are not efficient through the conventional service quality analysis and monitoring method. For example, if the total number of attempts made by the RNC corresponding to the base station controller is 10 calls for 5 minutes, the traffic rate is reduced to 80% even with 2 fluorides. It is difficult to determine and it is difficult to determine in which part of the mobile communication system an abnormality occurs.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is the loss of a protocol message on an interface for interworking between network components for service call processing in a communication network providing a mobile communication service. And it provides a protocol message monitoring system and method for notifying the operator by specifically identifying what interface and network configuration object of the communication network by analyzing and monitoring the error in real time.

In order to achieve the above object, the present invention receives various protocol messages transmitted and received on a section interface for interworking with objects of a communication network to form statistical results corresponding to the section interfaces, and based on the statistical results.

Advantageously, the system further comprises an input / output data processing server for broadcasting and delivering the result message provided from said interface analyzer to an operator computer.

In addition, the interface analyzer according to the second aspect of the present invention for achieving the above object, the real-time receiving the protocol message transmitted and received on the interface for each section for interworking between the objects of the communication network providing a mobile communication service A statistical result corresponding to the interface for each section is formed, and the message transmission loss rate and failure rate for each interface and the network constituent object are analyzed and processed based on the statistical result.

Preferably, the method further comprises the step of (e) the operator computer displaying the result message on the terminal screen in a text or GUI to indicate a corresponding interface and a network constituent object.

Send broadcast via protocol.

In addition, the communication network has a wideband code division multiple access (WCDMA) that facilitates the use of protocol message analysis by systematically defining interface definitions between network elements that make up a mobile communication system in preparation for a synchronous network. It is preferable to be implemented in a communication network. Accordingly, the following description will be made based on the WCDMA network 100.

The message collecting device 111 is implemented to include a MIDI gateway for supporting a protocol conversion function through interworking between networks, and an MSC (Mobile Switching Center) server for performing a call control function in the WCDMA network 100.

In addition, the types of protocol messages include a Radio Access Network Application Part (RANAP) protocol message and a WCDMA network (RANAP) on an interface between a radio network controller (RNC) and an MSC server 112, which constitute the WCDMA network 100. 100) BSSAP protocol message on the interface between the SGSN (Serving GPRS Support Node) and the MSC server 112, the Media Gateway Control (MEGACO) protocol message on the interface between the MSC server 112 and the media gateway, media There are ALCAP (Access Link Control Application Part) protocol messages on the interface between the gateway and the RNC, and other types of protocol messages may be further included according to an interface defined as a separate protocol in the WCDMA network 100.

The interface analyzer 120 compares the MEGACO protocol message provided from the MSC server 112 with the MEGACO protocol message provided from the media gateway, and determines whether the message transmission loss rate and the failure rate coincide with each other. In addition, the message transmission loss rate and failure rate can be calculated more precisely.

In addition, the protocol message monitoring system is connected to the media gateway and the MSC server 112 through the Telnet protocol so that the interface analyzer 120 can receive the real-time protocol messages for each interface. 112) It is preferable to further include an element management system (EMS) server that performs a telnet matching for each other.

Furthermore, the interface analyzer 120 may collect and statistics the protocol messages provided from the media gateway and the MSC server 112 so as not to collect the statistical results. In this case, the statistic range for each protocol message is gradually expanded (for example, the statistic range for collecting protocol messages for 5 minutes is extended to 10 minutes to collect protocol messages to expand the statistic range). Based on the collected protocol messages, more accurate statistical results are formed.

In addition, when the collection amount of the protocol message is small, it is possible to compensate for the small collection amount of the protocol message by analyzing each protocol message transmitted and received on each interface over the overlapping time range.

The interface analyzer 120 provides the operator computer 200 through the input / output data processing server 130 to the operator computer 200 when the message transmission loss rate and the failure rate exceed a predetermined threshold value based on the statistical result formed above. The alarm information is formed, and the alarm information is included in the result message and transmitted to the operator computer 200.

Accordingly, the interface analyzer 120 executes a process of forming a statistical result corresponding to the interface for each section based on each provided protocol message (S106).

Based on the statistical results formed in step S106, the interface analyzer 120 executes processing for analyzing message transmission loss and failure rates for the interface and the network constituent objects in the WCDMA network 100 to facilitate the operator's network abnormality. A result message is generated to be grasped (S108). Thereafter, the interface analyzer 120 transmits the result message to the input / output data processing server 130 (S110), and the input / output data processing server 130 re-delivers the received result message to at least one operator computer 200. Transfer (S112).
