Description

The present invention relates to a communication network management device that manages a communication network including one or more communication devices, and a journal data management method in the communication network management device .

  Conventionally, comprehensive monitoring of a communication network has been performed by an integrated management operation system. When a failure occurs in the communication network, an important failure message is transmitted from the communication device constituting the communication network to the integrated management operation system. In response to this, the system collects journal data of communication devices constituting the communication network in accordance with an application program in which a failure recovery procedure is made a knowledge base. For example, a similar technique in plant monitoring control is mentioned in Patent Document 1 below.

Here, the journal data is a record of the date and time of occurrence of the autonomous message detected by the communication device, the contents thereof, command information input by the maintenance person, and the like, and is used for specifying a failure factor of the communication device. When a failure occurs in a communication network in which communication devices are organically coupled, it is difficult to specify the cause of the failure unless these journal data are comprehensively analyzed.

  However, when multiple critical failure messages are sent from the communication device, that is, when multiple failure warnings occur in the communication network, journal data collection processing conflicts or duplicate journal data is collected. As a result, the processing time for specifying the failure factor may become long. In addition, when the collection processing of journal data is concentrated, there is a risk of overloading the communication network and squeezing the processing capacity of the entire communication system.

The present invention has been made to solve the above problems, and an object thereof is to provide a network management instrumentation 置及 beauty journal data management method capable of reducing the failure factor specific speeding when a failure occurs .

In order to achieve the above object, a communication network management device according to the present invention is a communication network management device that manages a communication network including one or more communication devices.

Request to refer to journal data If the journal data reference means can refer to the journal data corresponding to the communication device and the time, it performs failure determination and failure factor estimation from the referenced journal data. Management network communication means for acquiring and determining failure and estimating cause of failure .

  Here, the communication device corresponds to, for example, an exchange in a mobile communication network or a device in a base station.

  In the communication network management apparatus according to the present invention, the journal data acquisition means acquires journal data from the communication apparatus at an appropriate period or timing such as a fixed interval. The acquired journal data is stored by the journal data storage means in association with the acquired time and information about the acquired communication device.

  When an important failure message is transmitted from the communication device and the cause of the failure of the communication device is specified, the journal data reference means specifies the stored journal data based on the time and information related to the communication device, and the specified journal data is refer.

  As described above, the communication network management apparatus according to the present invention can acquire the journal data periodically and store it together with the information for search, so that it can be referred to appropriately when specifying the failure factor. Specific speedup can be achieved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an overall configuration of a communication system including a communication network management apparatus 10 according to the present embodiment. The communication system includes a communication network management device 10, a plurality of communication devices 20, and a communication network N. The communication network N is configured separately from the communication device 20 in FIG. 1, but includes the communication device 20. Here, the communication device 20 corresponds to, for example, an exchange in a mobile communication network or a device in a base station, and the communication network N corresponds to, for example, a mobile communication network.

  The communication network management apparatus 10 is a main function of an integrated management operation system that comprehensively monitors and manages the communication network N, that is, a function of receiving a critical failure message from the communication apparatus 20, and acquisition of journal data of the communication apparatus 20. Responsible for storage functions.

  The communication network management apparatus 10 includes a journal data acquisition unit 11, a journal data storage unit 12, a journal data reference unit 13, and a communication network management unit 18 that manages the overall functions of communication network management. Each function of the communication network management unit 18 will be described later.

  The journal data acquisition unit 11 acquires journal data from each communication device 20. The acquisition is performed via an operation system (not shown) that aggregates the communication network N and the communication device 20 as shown in FIG. Further, it is preferable that the acquisition is performed periodically, for example, by holding a rule regarding the acquisition time in the journal data acquisition unit 11.

  The journal data storage unit 12 stores various tables in association with the time when the acquired journal data is acquired and the information related to the acquired communication device 20.

  In response to a request from the communication network management unit 18, the journal data reference unit 13 specifies stored journal data based on time and information related to the communication device 20, and refers to the specified journal data.

  Next, various tables held in the journal data storage unit 12 will be described. The journal data storage unit 12 holds a message table 12a and an acquisition time table 12b.

  As shown in FIG. 2, the message table 12a is the main body of journal data acquired by the journal data acquisition unit 11, stores the content of the message detected by the communication device 20, and specifically, stores the journal data. A “communication device number”, “message generation date and time”, and “message content” that specify the acquired communication device 20 are stored. For example, the data on the first line indicates that the message “failure occurrence” is detected at “2004/1/2 0:00” in the communication device “NE11”.

  As shown in FIG. 3, the acquisition time table 12b stores the time when the journal data acquisition unit 11 acquires the journal data. Specifically, the “communication device” identifies the communication device 20 that acquired the journal data. The “number”, “acquisition start time”, and “acquisition end time” are stored. For example, the data on the first line indicates that the communication device “NE11” has acquired journal data from “2004/1/2 0:00” to “2004/1/3 23:59”.

  Hereinafter, processing executed by the communication network management apparatus 10 according to the present embodiment will be described with reference to FIGS. 4 and 5. In this embodiment, there are two types of processing: journal data acquisition processing and journal data reference processing.

  The journal data acquisition process will be described with reference to the flowchart of FIG. First, the journal data acquisition unit 11 determines whether or not it is time to acquire journal data from the current time based on a rule relating to the acquisition time held in advance (S01). It is assumed that this determination is always made when the communication network management apparatus 10 is operating.

  If it is determined that journal data is to be acquired, the journal data acquisition unit 11 acquires journal data of the communication device 20 included in the communication network N via the operation system (S02).

  Subsequently, the journal data storage unit 12 stores the acquired journal data in association with the acquired time and the communication device number related to the acquired communication device 20 using the message table 12a (S03).

  Subsequently, the journal data acquisition unit 11 determines whether or not it is time to end the acquisition of journal data from the current time based on a rule relating to the acquisition time held in advance (S04). When it is determined that it is time to end, the journal data storage unit 12 stores the acquisition start time and the end time using the acquisition time table 12b. If it is determined that it is not time to finish, the journal data acquisition unit 11 acquires journal data again. The above is the journal data acquisition process.

  Next, journal data reference processing will be described with reference to the flowchart of FIG. This process is executed when an important failure message is transmitted from the communication device 20 to the communication network management device 10 and the communication network management device 10 determines a failure and estimates a failure factor.

  First, the communication network management unit 18 activates an application program in which a procedure for performing failure determination and failure factor estimation is made into a knowledge base, and performs processing according to the program. First, the communication network management unit 18 determines whether or not journal data needs to be analyzed for failure determination and failure factor estimation from an important failure message transmitted from the communication device 20 (S11). If it is determined that it is not necessary, failure determination and failure factor estimation are performed as they are.

  If it is determined that it is necessary, the communication network management unit 18 requests the journal data reference unit 13 by designating the communication device 20 and the time so as to refer to journal data necessary for failure determination and failure factor estimation (S12). ). For example, the request is made in the format of journal data in the period from “2004/1/2 1:00” to “2004/1/3 2:00” in the communication device number “NE11”.

  The journal data reference unit 13 refers to the acquisition time table 12b of the journal data storage unit 12 and determines whether or not the target data exists (S13). When it is determined that the target journal data does not exist, the journal data reference unit 13 informs the communication network management unit 18 of the fact, and the communication network management unit 18 separately acquires the journal data to determine the failure. And failure factor estimation.

  For example, when there is a request in the above example and the acquisition time table 12b stores the data shown in FIG. 3, it is determined that the target journal data exists. In that case, the journal data reference unit 13 refers to the target journal data from the message table 12a of the journal data storage unit 12 based on the time designated by the communication network management unit 18 and the data related to the communication device 20, and the reference contents Is transmitted to the communication network management unit 18 (S14). For example, when there is a request in the above example and the acquisition time table 12b stores the data shown in FIG. 2, the journal data reference unit 13 indicates that the message content in the third line from the top of the data in the table of FIG. The data “communication failure occurrence” and the data “communication failure recovery” in the fourth row are referred to.

  The communication network management unit 18 performs failure determination and failure factor estimation from the reference content (S15).

  As described above, according to the present embodiment, by regularly acquiring journal data and storing it together with information for search, it is possible to refer to it appropriately when specifying a failure factor. Can be achieved. Further, since journal data is stored in advance, journal data collection processing at the time of failure factor identification can be reduced, and the burden on the communication network N can be reduced even when multiple alarms are concentrated. . Also, since regular journal data is held, it can be used for various purposes such as statistics.

  The journal data acquisition unit 11, the journal data storage unit 12, and the journal data reference unit 13 are provided in the communication network management device 10, but may be configured separately as a journal data management device having these components. In this case, the journal data reference unit 13 transmits journal data in response to a request from the communication network management apparatus 10.
