Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus and a method for network quality inspection in a wireless communication system,

The present invention relates to an apparatus and method for checking a communication system operation state in a wireless communication system.

The quality of voice over Internet Protocol (VoIP) service operation in a wireless network such as a wireless local area network (LAN) is affected by various components of a network, a place / time of occurrence, a VoIP application malfunction, User behavior, and so on. Even if it is installed considering wireless coverage, traffic dispersion, frequency / signal interference, terrain, etc. in the wireless network installation, it is possible to perform wireless communication by the user behavior, terminal operation system (OS) update, The network situation is constantly changing.

The VoIP service operator or the network administrator in the wireless network needs to know the VoIP service quality problem that can affect the business more quickly. Various analytical tools and tools have been developed to provide service quality problem detection / cause analysis / action guidance. For example, tools and methods have been continuously developed to continuously monitor the VoIP service quality to inform the user of an alarm, or to provide a service quality indicator / statistics to check whether there is an abnormality in the network operation status.

In the case of existing VoIP quality monitoring tools, it provides indices for VoIP quality deterioration, but analysis of causes of VoIP quality deterioration is limited, but it does not provide a cause for deterioration of sound quality. For example, since wireless fidelity (Wi-Fi) problems and statistics on VoIP quality are provided in a wireless network that can affect sound quality degradation, it is difficult to easily identify the cause of the degradation of VoIP sound quality and the relationship with the wireless network. In addition, since the provided VoIP quality index is provided as an index for the overall VoIP call quality, it is difficult to evaluate the individual call quality. Even if the individual call quality index is provided, it is difficult to analyze instantaneous sound quality deterioration such as instantaneous sound cut-off and sound cut-off. For example, it is difficult to distinguish between a wireless network problem and a client problem because a problem occurring according to various client devices is reported regardless of a wireless network problem. When comparing the indicators for all terminals and the indicators for specific terminal types, it can be seen that there is a problem in the specific terminal rather than the network problem. On the other hand, when the classification is not provided for the client terminal, it's difficult.

Therefore, in the conventional quality monitoring technology, there is insufficient correlation analysis between VoIP quality degradation phenomenon and the cause of providing wireless network, and there is insufficient correlation analysis between VoIP quality degradation phenomenon and terminal model, OS, VoIP client, There is a problem that it is difficult to detect and analyze the cause of the problem, and it does not accurately reflect the VoIP call quality experienced by the actual user.

One embodiment of the present invention provides an apparatus and method for monitoring network quality in a wireless communication system.

Another embodiment of the present invention provides an apparatus and method for analyzing logs in a wireless communication system.

Specifically, the event uses a method of analyzing an event in wifi_mac_log during a call end time (vqr_start_time + vqr_call_duration) from a call start time (vqr_start_time). The wireless event that can look at the wifi_mac log according to the VoIP client terminal behavior is shown in the above table. Referring to the above table, when Authenticated occurs in the wifi event (or wifi_mac log), the wireless node manager classifies it as a connect event. If Authenticated occurs after reassociation in the wifi event (or wifi_mac log), the APC classifies it as a roaming event. When a disassociation occurs after an association or reassociation occurs in a wifi event (or wifi_mac log), De-authentication occurs after an association or reassociation occurs, or an association occurs after an association or reassociation occurs, the wireless node management unit discoonect.

For example, the first MOS deterioration point is due to the occurrence of roaming to the wireless node 1 and the wireless node 2, the second MOS deterioration point is due to the occurrence of the packet loss event, and the third MOS deterioration point is the wireless disconnection point .

13 illustrates an example of wireless network event analysis using AP location information according to an embodiment of the present invention.

13 illustrates an example of a wireless network event extraction process according to an embodiment of the present invention. Referring to FIG. 13, the present invention provides additional cause analysis related to a wireless network event. For example, when extracting wireless network events from wifi_mac log (1310), Roaming Latency = Authenticated Time - Reassociation time can be calculated in case of Roaming event. If the roaming latency is large, it may be classified as a cause of the degradation of the VoIP sound quality, thereby providing the user with a more detailed sound quality degradation cause. As described above, the BSSID of the wireless node 1320 to which the terminal is connected / roamed can be extracted from the wifi_mac log. If the Controlled Network Environment Manager knows the setting of the network configuration such as the AP installation location information, the connected wireless node can be distinguished from the BSSID extracted from the log. Therefore, the wireless node roaming path 1330 and the wireless network Identify the wireless node that is experiencing the problem

FIG. 15 illustrates an example of a process for providing an analysis result according to an embodiment of the present invention.

Referring to FIG. 15, the node manager performs a log analysis engine in step 1510. FIG. The log analysis engine collects logs, analyzes logs, and reports the results of the analyzes. After performing the log analysis engine, the wireless node manager stores analysis data in step 1520. [ After storing the analysis data, the APC displays the analysis data stored in step 1530. When the user requests the analysis result, the wireless node management unit can display the analysis data stored through the web GUI or the like. In step 1540, the user selects a tone quality indicator reference through the displayed analysis data, and in step 1550, the wireless node manager classifies the problem item according to the selected tone quality indicator reference.

The voice quality indicator criteria may be a low average rate of communication, a low rate of communication with a low rate of MOS, a low rate of communication with low interval MOS, a wireless node with low RSSI, and the like. The tone quality indicator is not limited to the above, and various indicators such as an average MOS and the number of generated wireless interrupts during a call can be used. The case where the call rate at which the section MOS degradation occurs with respect to the category of the terminal OS (Operating System) is taken as an example based on the sound quality index, (Qos_thr) is a value obtained by dividing the number of calls in which the MOS sound quality degradation in the interval is divided by the number of all the calls do. That is, M / N = Qos_thr. On the other hand, the sound quality index based on the number of calls per OS is a value obtained by dividing the number of conversations in which the MOS sound quality degradation in the section of the terminal using a specific OS is lowered by the number of calls of the terminal using the specific OS. That is, if the number of calls in which the MOS sound quality degradation during the call of the terminal using the specific OS is referred to as M_OS and the number of calls of the terminal using the specific OS is defined as N_OS, the sound quality index (QOS_OS) / N_OS = Qos_OS. If the sound quality index based on the number of calls per OS is larger than the sound quality index based on the total sound quality index reference for all the calls and the OS-related number of calls per OS, the OS is judged to have a problem. That is, when the QOS_OS> QOS_THR, the wireless node management unit determines that the corresponding OS has a problem.

In step 1560, the wireless node management unit analyzes the items other than the problem item or the specific category item. For example, if there is a problem with a specific OS, the wireless node manager may exclude a specific OS category. As another example, if there is a problem with a specific terminal model, the wireless node manager may exclude the specific terminal model. A problem item or a specific category item may be excluded to solve a problem item or a problem of a specific category and to perform a more detailed analysis on the network except for an exceptional problem item or a specific category item. After analyzing the problem item or the specific category item, the wireless node management unit transmits the filtered data of the selected problem item and the specific category to the log analysis engine for analysis.

In step 1570, the wireless node manager provides a detailed VoIP list of the problem item. The wireless node management unit provides a more detailed VoIP list for the data classified as the problem item according to the quality criteria indicator selected in step 1550. [

In step 1580, the wireless node manager displays detailed VoIP. The wireless node management unit displays the status or detail status of the VoIP item desired by the user.
