Description

TECHNICAL FIELD [0001] The present invention relates to a system and method for real-time failure analysis based on network quality data,

More particularly, the present invention relates to a system and method for analyzing real-time failure cause based on network quality data, more specifically, analyzing large-capacity data capable of estimating a network quality state and quickly and accurately responding to a customer's failure (VOC) And more particularly, to a network quality data based real-time failure cause analysis system and method.

As the computer, electronic and communication technologies have developed dramatically, various services using communication networks have been provided. Recently, the internet (IoT), which communicates information between people, things, and things, is deeply ingrained in our everyday lives. Now, it is not only the network but the network quality plays a decisive role in the quality of the service using the network, and the provision of the network quality related service will be a basis for securing the initiative in various IT fields using the communication network. Therefore, Internet service providers are required to play a role as providers of services that can quickly identify network quality problems, analyze causes, and provide action guidelines beyond their role as network providers.

On the other hand, the types of terminals connected to the network have been diversified, and in particular, the kinds of the customer premises terminal (ex, internet modem, home hub, internet phone, TV settop, etc.) As the number and type of terminals connected to the network increases, the network connection method also becomes various, and the configuration of the network becomes complicated. Therefore, when a network failure occurs, it becomes more difficult and time-consuming to accurately grasp the location of a failure.

For example, when a fault event such as deterioration in sound quality or connection disconnection occurs during use of the customer terminal (ex, smart TV), it is not easy to distinguish whether the fault occurrence occurs at the customer terminal or the fault of the network itself to which the customer terminal is connected . In particular, if a failure occurs in some of the network devices belonging to the Internet, the failure of the network connection may occur simultaneously even in the customer terminal devices using the network through the failed network device.

However, the conventional network quality monitoring technology fails to distinguish whether the occurrence of a fault event is a problem of a network or a problem of a customer terminal. In addition, when there is a fault event occurring concurrently, It took a considerable time until the settlement. That is, in the conventional network quality monitoring technology, even if a customer receives a service quality complaint (eg, customer failure report: VOC), it is difficult to respond immediately.

In FIG. 2, the VOC operating device 60 is shown connected to the public network 1, but not limited thereto, and may be connected to the private network 2 according to another embodiment.

3 is a block diagram of the failure cause analysis apparatus of FIG.

The failure cause analysis apparatus 40 according to one embodiment may include a memory, a memory controller, one or more processors (CPUs), a peripheral interface, an input / output (I / O) subsystem, a display device, have. The memory may include high speed random access memory and may also include one or more magnetic disk storage devices, non-volatile memory such as flash memory devices, or other non-volatile semiconductor memory devices. Access to the memory by other components such as the processor and the peripheral interface may be controlled by the memory controller. The memory can store various information and program instructions, and the program is executed by the processor.

The peripheral interface connects the input / output peripheral device of the failure cause analysis device 40 with the processor and the memory. The one or more processors execute various sets of instructions stored in various software programs and / or memories to perform various functions and process the data for the failure cause analysis apparatus 40. The I / O subsystem provides an interface between I / O peripheral devices such as display devices, input devices, and peripheral interfaces. The display device can use liquid crystal display (LCD) technology or light emitting polymer display (LPD) technology.

The processor is a processor configured to perform an operation associated with the cause analysis device 40 and to execute instructions, for example, using instructions retrieved from the memory, to determine whether the input and output data Reception and operation can be controlled. The communication circuit performs communication via an external port or communication by an RF signal. The communication circuit converts the electrical signal to an RF signal and vice versa, and is capable of communicating with the communication network, other mobile gateway devices, and the communication device through the RF signal.

2 and 3, the failure cause analyzing apparatus 40 includes a collecting unit 41, a distributed processing unit 42, a network quality analyzing unit 43, a storage unit 44, an interlocking unit 45, (46, DB). Such components may be implemented in software, stored in memory and executed by a processor, or may be implemented in a combination of software and hardware.

The collecting unit 41 receives the log signal generated by the network terminals belonging to the public network 1 through the log collection gateway 30 and receives the network operation information from the communication facility operating apparatus 50 connected to the private network 2, Can be directly received. Here, the log signal may include location information (phase) of the network terminal that generated the signal and network connection information (ex, connectable, connection failure). The network operation information includes the location information (phase) of the network device 20 (21, 21, 23, 25, 27) and the current state information (ex, under construction, in use, . Here, the network terminal may include an in-house terminal 10 (10a, 10b, 10c) and a network device 20 (21, 23, 25, 27).

The distributed processing unit 42 can classify the log signal and the network operation information received from the collecting unit 41 into phases. IP, MAC, PORT, device type (e.g., IP address) of network terminals connected to the network section by referring to the network structure (pattern) stored in the database 46 type, equipment model name, etc.). The distributed processing unit 42 may analyze the log signal and the network operation information generated in the extracted network terminal and classify the network terminals having the failure event by phase.

For example, a method of classifying network terminals having a failure event according to their phases is as follows. Referring to FIG. 2, for example, a failure occurs in the first network device 21 and the local terminals 10 (10a, 10b, It is assumed that a temporary connection failure is scheduled at the time when the log signal is generated according to the periodic inspection of the first network device 21 . The distributed processing unit 42 may analyze the log signal and the network operation information for the fault event and classify them in the phase order. In other words, the distribution processing unit 42 may be configured to transmit the log signal to the first network device 21, the first network device 21, the first network device 21, Can be classified in phase order. At this time, the phase of the first network device 21 is the highest, and the phases of the local terminals 10 (10a, 10b, 10c) of the lower phase than the first network device 21 are the same.

The network quality analyzer 43 determines the position of the network terminal having the highest phase based on the information classified by the distributed processing unit 42 as the representative failure location according to the failure detection logic. Here, the representative failure location refers to a failure of a network terminal located at an arbitrary point, resulting in a failure of network terminals having a lower phase than the corresponding location, and when a failure of the corresponding network terminal is processed, the failure of network terminals of a lower phase is automatically resolved Define as fault location.

The network quality analyzer 43 determines the position of the network terminal where the log signal having the highest phase is generated as the representative failure location when there are a plurality of log signals having the failure event information according to the failure detection logic. In addition, when there are a plurality of log signals having the highest phase, the network quality analyzing unit 43 determines the position of the network terminal where the log signal is most recently generated as the representative failure position. That is, according to the fault detection logic, when a fault event occurs in a network terminal of a higher phase, the location of the lower-phase network terminal can not be a representative fault location until the fault is eliminated. Accordingly, once the representative failure location is set, the network quality analysis unit 43 maintains a predetermined representative failure location during the failure settlement period set by the administrator. However, if the network quality analyzer 43 receives a new failure event before the fail-over time elapses, the network quality analyzer 43 determines that the phase of the network terminal corresponding to the newly received failure event is less than the phase of the network terminal selected as the current representative failure location If it is higher or lower, the position of the network terminal corresponding to the newly received failure event can be changed to the representative failure position.

The storage unit 44 can store the analysis result of the network quality analysis unit 43, that is, the representative failure location, and can update and receive the representative failure location every predetermined period. The representative failure location can be updated Lt; / RTI > The storage unit 44 may transmit the representative fault location stored at the request of the interlocking unit 45 to the interlocking unit 45.

The interlocking unit 45 may transmit a representative failure location and a VOC failure action guide related to the VOC customer to the VOC operating device 60 according to the contents requested by the VOC operating device 60. [ That is, when the analysis of the cause of the network failure is requested from the VOC operating device 60, the interlocking unit 45 extracts the network segment associated with the customer line number from the database 46 (DB) Can be received from the storage unit 44 and fed back together with the VOC trouble shooting guide. Here, when feedback is performed, information such as a failure event log signal generation time, a failure event code (event_code), a connection order (con seq), a cause cause, an action guide, a terminal classification, .

The database 46, DB can store network patterns, failure detection logic, network fault information, pre-check target information, VOC failure action guide analysis information, and the like. Here, the network pattern can be analyzed and extracted from the client terminal 10 and the network device 20 (21, 23, 25, 27) that generated the log signal, and the pre-check target information can be extracted from the communication facility operating device 50 May be extracted from the received network operation information and stored in the database 46 (DB).

4 is a flowchart illustrating a network quality data based real-time failure cause analysis method according to another embodiment.

Referring to FIGS. 2 to 4, the failure analysis device 40 may analyze the network quality data to extract a failure event (S1). The network quality data may include a log signal received through the log collection gateway 30 (GW) and network operation information received from the communication facility operation device 50.

The log signal may include network terminal information and a failure event (ex. Connectable, connection failure) that generated the signal, and the network terminal information may include information (IP address) of the customer's internal terminal 10 (10a, 10b, 10c) (Equipment type, equipment model name, etc.) of the network device 20, 21, 23, 25, 27, The network operation information includes information on the specific network device ex 23 (equipment type, equipment model name, etc.) to be subjected to construction or inspection among the network devices 20: 21, 23, 25 and 27, ex, 23) position information (phase) and current state information (ex, under construction, in use, unused, etc.).

The failure event extraction step S1 is a step of extracting a network section by customer (ex, customer line number) by referring to the network structure (pattern) stored in the database 46 (DB) Selecting a log signal generated in network terminals belonging to each of the derived network sections and network operation information belonging to the derived network section from among the selected log signals and network operation information, And extracting operational information. Here, the network terminal may include an in-house terminal 10 (10a, 10b, 10c) and a network device 20 (21, 23, 25, 27).

Next, the failure analysis device 40 classifies the network terminal corresponding to the log signal having the failure event and the network operation information into phases, and determines the position of the network terminal having the highest phase as the representative failure position (S2) . In the representative fault location determination step S2, when there are a plurality of network terminals having the highest phase, the fault cause analysis apparatus 40 distinguishes the fault event occurrence time point and notifies the fault event to the location of the network terminal As the representative fault location.

For example, referring to FIG. 2, the failure analysis device 40 includes a local terminal 10 (10a, 10b, 10c) and a first network device 21 that have generated a log signal for a failure event, It is possible to classify the first network device 21 to which the connection failure is scheduled in phase order. At this time, the failure analysis device 40 can determine the position of the first network device 21 having the highest phase as the representative failure position.

In addition, the failure analysis device 40 selects a representative failure location for the entire network at regular intervals, updates and stores the updated information with the latest information, and if the analysis is for an analysis of the cause of the network failure from the VOC operating device 60, Thereby enhancing service satisfaction.

Next, the failure cause analysis device 40 is requested to analyze the cause of the network failure from the VOC operating device 60 (S3). The failure cause analysis device 40 can also receive VOC customer information when it is requested to analyze the cause of the network failure. The VOC customer information may include the customer line number.

Next, the failure cause analysis device 40 transmits an analysis result corresponding to the VOC customer information (S4). That is, the failure analysis unit 40 can extract a network section related to the customer line number and feed back the representative failure location of the extracted network section to the VOC operating apparatus 60 together with the VOC failure action guide. Here, the analysis result includes a representative failure location (event_code), a failure event occurrence time, a connection order (conn seq), a cause cause, an action guide, network terminal information (ex, IP, MAC , Type), and the like.

5 is a flowchart illustrating a method for updating a representative failure location upon receipt of a new failure event according to another embodiment.

After the representative failure location is determined according to FIG. 4, the principle representative failure location is maintained during the failure resolution period to secure time for the failure to be resolved. FIG. 5 shows a processor that is executed in the failure analysis apparatus 40 when a log signal or network operation information having a new failure event is received before a fail-over period elapses in FIG. That is, FIG. 5 illustrates a specific embodiment of the representative fault location determination step S2 shown in FIG.

Referring to FIG. 5, the failure analysis apparatus 40 may receive a new log signal or network operation information having a failure event before the fail-over period elapses (S51).

Next, the failure analysis unit 40 determines whether the phase of the network terminal corresponding to the new failure event log signal or the network operation information is higher than the phase of the representative failure position (S53). According to one embodiment, when a plurality of new failure events are received, the failure cause analysis apparatus 40 derives a network terminal having the highest phase by combining phases of a plurality of network terminals corresponding to a new failure event, It can be determined whether or not the phase of the derived network terminal is higher than the phase of the representative fault location.

If the phase of the new failure event is higher than the phase of the representative failure position (S53, Yes), the failure analysis device 40 returns the position of the network terminal corresponding to the new failure event log signal or the network operation information to the representative failure position (S54).

If the phase of the new fault event is not higher than the phase of the representative fault location (S53, No), the fault cause analysis apparatus 40 determines whether the phase of the new fault event log signal or the network operation information matches the phase of the representative fault location (S55).

If the phase of the new fault event and the phase of the representative fault location are the same (S55, Yes), the fault analysis apparatus 40 changes the location of the network terminal corresponding to the new fault event log signal or the network operation information to the representative fault location (S56). The failure analysis apparatus 40 maintains the representative failure location of the newly changed representative failure position from the point of change to the representative failure position during the failure resolution period.

If the phase of the new fault event and the phase of the representative fault location are not identical (No at S55), the fault analysis apparatus 40 maintains the current representative fault location for the fault resolution period (S57). The failure cancellation period can be set by the administrator as a time that the network terminal at the current representative failure location can be repaired and returned to the normal state.
