Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility monitoring method and system for monitoring the state of a facility, and more specifically, a plurality of facilities capable of assuming a unique state and a plurality of similar types having a unique hardware configuration. The present invention relates to an equipment monitoring method and system for monitoring the status of equipment.

[0002]

2. Description of the Related Art For example, a mobile communication system is composed of many network devices (NE) such as base stations, exchanges, control station devices, and the like. An equipment monitoring system that monitors the status of each network device (equipment) in such a mobile communication system determines the status of each part of the network device from the information (device status data, abnormality detection signal, etc.) collected from each network device. Recognize and show the state to the maintenance person. The maintenance person and the administrator of the mobile communication system perform maintenance and operation of the mobile communication system based on the state of each part of each network device presented from the equipment monitoring system.

[0003]

By the way, it has been proposed to construct a mobile communication system by supplying the above-mentioned network device (equipment) from a plurality of manufacturers (hereinafter, the system is constructed in this way). A person who provides equipment for doing so is called a vendor). When constructing the mobile communication system in this way, each vendor can design and manufacture a network device for exhibiting a desired function in the mobile communication system according to its own design concept. Therefore, it becomes possible to construct a mobile communication system earlier by using a network device of higher quality that makes use of the experience and know-how of each vendor.

However, if each network device is uniquely designed and manufactured by a plurality of vendors as described above, the possible states of each part of the network device may differ from one vendor to another. For example, one vendor's network device may have three states (A, B, C), while another vendor's network device has five states (A, B, C).
1, A2, B, C1, C2) may be possible.

In this way, when the network devices of the respective vendors have different possible states, there are many types of states that can be presented to the maintenance person by the equipment monitoring system. For this reason, it becomes difficult for the maintenance person to judge the unified state of each network device based on the state presented by the monitoring system.

Further, even if the same type of network device is used, the hardware configuration may be different if the vendor is different. For example, the number of panels (cards) accommodated in the rack of the same type of network device, the circuit configuration on each panel, the arrangement order of the panels, and the like vary from vendor to vendor.

As described above, when the same type of network device has a different hardware configuration for each vendor, the network device of each vendor determines what kind of communication service a failure of a certain hardware part (for example, a panel) affects. It varies. For this reason, it becomes difficult to make a unified judgment of the failure status based on the status (normal, abnormal) of each hardware part presented from the equipment monitoring device.

As described above, when it becomes difficult to determine the unified state (fault condition, etc.) of each network device (equipment), it results in efficient maintenance and operation of each network device in the mobile communication system. It gets harder.

Therefore, an object of the present invention is to provide a facility monitoring method and system capable of integrally determining the states of a plurality of facilities that can assume unique states or a plurality of similar types of facilities that have unique hardware configurations. Is to provide.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

The equipment monitoring system according to the first embodiment of the present invention is configured, for example, as shown in FIG.

In FIG. 1, equipment to be monitored, for example, exchanges 10 (1) and 10 (2) are connected to each other in a mobile communication system. This exchange 10
(1), 10 (2) are provided with devices E1, E2, ... For exhibiting a switching function in a mobile communication system. These exchanges 10 (1), 10 (2) are provided by different vendors (α, β), and each of the defined devices E1, E2, ... Can have a device state (detailed state described later). Is different for each exchange 10 (1), 10 (2). The configuration of each device included in each exchange 10 (1), 10 (2) may be the same or different.

Further, each exchange 10 (1), 10 (2)
Has a device state data generation unit 11 and a communication unit 12. The communication unit 12 is a network system N for monitoring.
It is connected to the monitoring server (OPS server) 100 via. Further, monitoring terminal devices (OPE) 110 and 120 are connected to the monitoring server 100 via an integrated LAN. The monitoring server 100 includes the exchanges 10 (1), 10
By communicating with the communication unit 12 of (2), each device E generated by the device state data generation unit 11 will be described later.
The device state data representing the states of 1, E2, ... Is acquired. Then, each of the monitoring terminal devices 110 and 120 is connected to the monitoring server 1
The device status data of each of the exchanges 10 (1), 10 (2) collected at 00 is acquired via the integrated LAN, and each exchange 10 (1) is acquired based on the device status data according to a predetermined operation of a maintenance person. ) Display the status of each device in 10 (2).

The device status data generator 11 has a mapping table for mapping the detailed statuses of the respective devices E1, E2, ... Defined in each exchange to the logical states required for efficient maintenance and operation. The above logical state is
For example, it is determined as follows.

When performing maintenance and operation of a certain device, the necessary logical states are "operation" and "failure".

When there are only two logical states of "operating" and "failure" as described above, and when the maintenance person disconnects the device from the operating system, the logic state of the device becomes "failure". However, efficient maintenance and operation can be performed by making it possible to distinguish between a "failure" when a failure has really occurred and a "failure" when the maintainer disconnects it from the operating system. Therefore, "maintenance" is defined, which represents the logical state separated from the active system by the maintainer.

Further, when considering a set of duplicated devices, the state of the standby device in the set of devices is different from the "active" state. By defining such a state as "standby", which is distinguished from "operating", efficient maintenance and operation can be performed.

Further, when considering a set of devices that are in a hierarchical relationship, the logical state of each device is "operating",
It can be represented by “fault” and “maintenance”. However, when the higher-level device becomes “failed”, the lower-level device itself is not functioning normally even if it is normal. If such a state is a "failure", it cannot be distinguished from its own "failure". Therefore, in order to distinguish the above-mentioned states, the state of the lower-level device that does not function normally due to the "failure" of the upper-level device is defined as "related fault".

As described above, "operating", "standby", "failure", "related failure", and "maintenance" are defined as the minimum required logical states for efficient maintenance and operation of each device. .

The mapping table provided in the device status data generator 11 is as shown in FIG. 2, for example.

In FIG. 2, there are 11 kinds of detailed states defined as possible states of the respective devices E1, E2, ... Of the exchange 10 (1) provided by the vendor α.
The mapping table provided in the device status data generation unit 11 of (1) maps (corresponds) the eleven kinds of detailed statuses to the five logical statuses. Further, there are nine kinds of detailed states defined as the states that can be taken by the respective devices E1, E2, ... Of the exchange 10 (2) provided by the vendor β, and the device state data generation unit 11 of the exchange 10 (2) is provided. The mapping table maps (associates) the nine kinds of detailed states to the above five logical states.

Specifically, in the mapping table provided in the device status data generation unit 11 of the exchange 10 (1) (vendor α), a state in which it operates as a single device (in operation (single device)), The two detailed states of the state (operating (duplexing device)) operating as one device of one set of the duplicated devices are associated with the logical state “operating”, and one of the one set of the duplicated devices The standby state (standby (duplexing)) of the device is the logical state "standby"
Is associated with. In addition, the status has been suspended due to a command, the status has been disconnected from the active system due to formatting, the status has been disconnected from the active status due to copying information for recovery, and the status has been disconnected from the active status due to self-diagnosis. Five detailed states of the state are associated with the logical state “maintenance”. Furthermore, the two detailed states of the service being stopped due to the failure and the status of self-diagnosis after the failure are associated with the logical state "failure", and the higher-level device, which is the unification device, exhibits normal functions depending on the failure. Two detailed states, that is, a state in which they do not operate normally and a state in which a pair of higher-level devices that are redundant apparatuses do not perform their normal functions due to a failure, are associated with the logical state “related failure”.

Further, in the mapping table provided in the device status data generator 11 of the exchange 10 (2) (vendor β), the operating status (regardless of the simplex device or the duplexer) becomes the logical status "active". The logical state “waiting” is associated with the associated state. Also,
A state in which operation has been suspended by a command, a state in which it is disconnected from the active system due to formatting, a state in which it is disconnected from the active system due to copying information for recovery,
Five detailed states, which are separated from the active system due to the normal data being downloaded, are associated with the logical state "maintenance". Further, two detailed states, that is, a state in which service is stopped due to a failure and a state in which normal data is downloaded after the failure, are associated with a logical state “failure”, and a higher-level device (regardless of a single device or a dual device) The state in which the normal function is not exerted due to the failure is associated with the logical state “related failure”.

With the mapping table as described above,
Even if the detailed information defined by the exchange differs for each vendor, each detailed information is associated with any of the above five logical states.

The device state data generator 11 generates device state data representing the logical states of the devices E1, E2, ... In accordance with the procedure shown in FIG. 3, for example.

A certain device in the exchange is designated (S1), and it is determined whether or not there is a higher-level device related to the device (S2). When there is no higher-level device related to the designated device (NO in S2), the state (detailed state) of the designated device is checked to acquire the detailed state (S3). Then, the acquired detailed state is converted into a corresponding logical state by referring to the above-mentioned mapping table (see FIG. 2) (S4). The obtained logical state is recorded in a predetermined memory in association with the designated device (S5).

On the other hand, when there is a higher-level device related to the designated device (YES in S2), the state (detailed state) of the higher-level device is checked to acquire the detailed state ( S8). After that, the state (detailed state) of the designated device is checked to acquire the detailed state (S3). In this way, when the detailed state of both the designated device and its superordinate device is acquired, the detailed state of the designated device is determined based on the detailed state of the device.
The mapping table is referred to and converted into a corresponding logical state (S4). For example, the detailed status of the upper device is in failure (in the case of a redundant device, one set of upper devices is in failure).
If so, the detailed state is converted into the logical state “related failure” regardless of the detailed state of the designated device. Also,
If the detailed state of the upper device is not in failure, the detailed state of the designated device is converted into a corresponding logical state by referring to the mapping table. Then, the obtained logical state is recorded in a predetermined memory in association with the designated device (S5).

It is judged whether or not the detailed states of all the devices in the exchange have been converted into logical states (S6). If the detailed states of all devices have not been converted to logical states (S6)
No), another device is designated (S1), and the above-described processing (S2 to S5, S7) is executed. Then, the processes (S1 to S7) described above are repeatedly executed until the processes for all the devices included in the exchange are completed.

When the processing for all the devices included in the exchange is completed (YES in S6), the device state data representing the logical state obtained for each device is set in a predetermined register for each corresponding device. (S8).

The device status data generating section 11 of each of the exchanges 10 (1) and 10 (2) executes the above-mentioned processing with, for example, an interrupt signal from a timer, so that each device in the exchange has a predetermined cycle. Device state data representing a logical state is generated.

The monitoring server 100, which monitors each of the exchanges 10 (1), 10 (2), has a device state indicating the logical state of each device provided in each of the exchanges 10 (1), 10 (2) at predetermined intervals. Data is collected, for example, according to the procedure shown in FIG. In FIG. 4, each exchange 10
(1) and 10 (2) are generally indicated by reference numeral 10.

In FIG. 4, the monitoring server 100 transmits a command request signal (CMD_REQ) to the exchange 10 via the network system N. The communication unit 12 of the exchange 10, which has received the command request signal, transmits a confirmation signal (CMD_REQ_ACK) to the monitoring server 100 if the communication unit 12 is in a communicable state. After that, the communication unit 1 of the exchange 10
2 transmits a data write request signal (DT_WT_REQ) to the monitoring server 100. When the monitoring server 100 receives this data write request signal (DT_WT_REQ), if the data acquisition is possible, its confirmation signal (DT_WT_AC).
K) to the exchange 10. This confirmation signal (DT_WT_AC
The communication unit 12 of the exchange 10 that has received K) receives the device status data set in a predetermined register of the device status data generation unit 11 as described above by a predetermined amount.
Send to 0.

Thereafter, each time the data write request signal (DT_WT_REQ) and its confirmation signal (DT_WT_ACK) are exchanged between the exchange 10 and the monitoring server 100, a predetermined amount of device data is transferred from the exchange 10 to the monitoring server 100. To be done. Then, the communication unit 12 of the exchange 10 transmits a data end request signal (DT_END_REQ) to the monitoring server 100 when the transfer of all the device state data set in the predetermined register of the device state data generation unit 11 is completed. The monitoring server 100, which has received the data end request signal (DT_END_REQ), transmits the confirmation signal (DT_END_ACK) to the exchange 10. As a result, the collection of the device status data from the exchange 10 by the monitoring server 100 is completed.

In the above example, the case of monitoring the exchange in the mobile communication system has been described, but the monitoring server 100 similarly applies to other equipment, base stations, control stations, etc. in the mobile communication system. It is possible to collect device state data representing the logical state of each device constituting the.

In the above example, each exchange (equipment) generates device state data for each device at a predetermined cycle,
Monitoring server 100 has a predetermined cycle (different from the above predetermined cycle)
Although the device status data is collected from each exchange, the method of collecting the device data by the monitoring server 100 is not limited to this. For example, each exchange (equipment)
It is also possible to cause the exchange to report the device state data of each device to the monitoring server 100 every time the device state data of each device generated in the predetermined cycle changes.

The maintenance person can know the state of each equipment of the mobile communication system by operating the monitoring terminal devices 110 and 120.

When the monitoring terminal device 110 is operated to activate the monitoring system, the monitoring terminal device 110 is activated by the monitoring server 1.
00, and a monitoring equipment designation screen as shown in FIG. 5, for example, is displayed. On this monitoring equipment designation screen, the type of equipment to be monitored, for example, exchange 1 (MM
S), exchange 2 (NMLS), subscriber center equipment (M-SCP),
... is displayed. Then, when the maintenance person clicks on the type of equipment whose state is to be monitored, for example, the exchange 2 (NMLS) and specifies the equipment whose state is to be monitored, for example, the mobile communication system as shown in FIG. A screen showing a list of equipment of that type included in is displayed. Further, when the maintenance person clicks on the equipment whose status is to be monitored on the list screen and designates the equipment, for example, the system configuration of the designated equipment and its state as shown in FIG. 7 are displayed. The system status display screen is displayed.

This system status display screen is generated as follows.

The designated facility configuration (system configuration) is graphically displayed. In the example shown in FIG. 7, a switch (SW), a repeater (HUB), a maintenance processor (OMP), a common line processor (CSD), a LAN, and a L provided in the exchange.
The controller (COC) of the AN, the interface (MIF) with other nodes, the master clock (MCLK), and the controller (SVC) are displayed by graphical elements. Each element has a display section for displaying its state. The 0-system display unit and the 1-system display unit are provided in the element corresponding to the duplicated device. Further, elements corresponding to a plurality of existing devices such as a LAN and its controller (COC) are provided with corresponding display units.

Each display unit corresponds to one of the logical states “operating”, “standby”, “maintenance”, “fault”, and “related fault” represented by the device state data acquired for the corresponding device. , Colors, marks, etc. are displayed. In the case shown in FIG. 7, a color (black) indicating “fault” is displayed on the display unit corresponding to the 0-system device and the 1-system device of the element corresponding to the repeater (HUB). A mark (diamond) indicating "related failure" is displayed on the display portion of the element corresponding to the switch (SW) that is the relay device (HUB) that is a higher-level device. In addition, a color (white) representing "operating" is displayed on the display unit corresponding to the 0 system device of the element corresponding to the maintenance processor (OMP), and a "standby" is displayed on the display unit corresponding to the 1 system. Is displayed (dots).

In this way, the system status screen displayed on the monitoring terminal device 110 graphically represents the logical status of each device of the exchange, so that the maintenance person can easily judge the state of the exchange. can do. Also,
With respect to other equipment, the state of each device included in the equipment is represented by one of the above-mentioned five logical states, so that the maintenance person can determine the states of various equipment in a unified manner. As a result, efficient maintenance and operation of each facility that constitutes the mobile communication system is facilitated.

In the above example, each exchange (equipment)
The conversion of the detailed information of each device into the logical state in (1) is performed by each exchange, but the present invention is not limited to this. Each exchange (facility) reports detailed information of each device to the monitoring server 100, and the monitoring server 100 refers to the mapping table as shown in FIG. Data may be created.
Also, each exchange (facility) reports detailed information of each device to another server connected to the monitoring network, and that server converts the detailed state reported to a logical state to create device state data. The device status data can be reported from the server to the monitoring server 100.

Each device constituting the above equipment may be physically distinguishable or functionally distinguishable.

When the alarm level is calculated, model information (vendor name, model name, machine number, etc.) identifying the base station, abnormal panel information indicating the panel in which the above abnormality occurred, abnormality indicating the functional block corresponding to that panel The function block information and alarm level information indicating the calculated alarm level are generated (S15). Then, the abnormality information generation unit 22 uses the communication unit 23 as abnormality detection data in which the generated model information, abnormal panel information, abnormal block information, and alarm level information are arranged in a common format defined by the system.
(S16).

The communication unit 23 that has acquired this abnormality detection data
Transmits the abnormality detection data to the monitoring server 200 via the network system N.

Calculation of the above alarm level (S in FIG. 13)
14) is performed as follows, for example.

The abnormality information generating unit 22 has, for each functional block, normal (Normal): no failure occurs in the functional block alarm L (Low-ALM): failure occurs in the functional block. State However, if the current operating part fails, the function can be maintained in other parts (redundant configuration is secured) Alarm H (High-ALM): The functional block has failed. However, the current operating part has failed. If it does, the function will be stopped (redundant configuration is not taken). Failure alarm (System-ALM): Has an alarm mapping table that defines the failure status corresponding to each alarm level of the function stopped. . This alarm mapping table is configured as shown in FIG. 14, for example. This alarm mapping table defines the failure status of each vendor for the baseband unit (functional block).

In FIG. 14, the baseband section of the base station of the vendor A (four panels 19 to 22: see FIG. 9) is
If all four panels are normal, then normal (Norm
If one or two of the four panels are abnormal and the rest are normal, an alarm L (Low-AL
M) alarm level, when 3 out of 4 panels are abnormal and the remaining 1 panel is normal, it is alarm H (High-ALM) alarm level, and 4 more When all the panels of are abnormal, it is the alarm level of the failure alarm (System-ALM).

The baseband section of the base station of the vendor B (two panels 1 and 2; see FIG. 10) is normal when all of the two panels are normal.
If one of the two panels is abnormal and the remaining one panel is normal, it is an alarm level of alarm H (High-ALM), and if all two panels are abnormal,
It is a failure alarm (System-ALM). The alarm level of the alarm L (Low-ALM) is not defined for the baseband part of the base station of the vendor B.

Baseband part of the base station of vendor C (three of c panels 25 to 27 and four of d panels 28 to 31:
(See FIG. 11) is normal when all of the three c panels 25 to 27 and the four d panels 28 to 31 are normal, and is one of the three c panels 25 to 27.
If one panel is abnormal or one or two panels out of the four d panels 28 to 31 are abnormal, an alarm L
(Low-ALM) alarm level, 3 c-panels 25
2 to 27 panels are abnormal, or 3 panels out of 4 d panels 28 to 31 are abnormal, it is an alarm level of alarm H (High-ALM), and 3 c panels. 25-27 are all abnormal, or 4 d panels 28-3
When 1 is all abnormal, it is an alarm level of a failure alarm (System-ALM).

After identifying the panel in which the abnormality has occurred (S12 in FIG. 13), the abnormality information generating unit 22 determines the relationship between the number of panels in which the abnormality has occurred and the number of all blocks constituting the functional block to which the panel belongs. Based on the above, referring to the alarm level mapping table (see FIG. 14), 3
Determine any of the alarm levels of stages (Low-ALM, High-ALM, System-ALM). And the alarm level information showing the determined alarm level is produced | generated.

The monitoring server 200, which has received the abnormality detection data transmitted from the communication unit 23 of the base station via the network system N as described above, follows the instruction from the monitoring terminal device 210 and displays the abnormal portion display control and functional blocks. Perform display control. By the abnormal portion display control, the following graphical panel alarm screen is displayed on the monitoring terminal device 210.

A panel configuration diagram of the base station specified by the model information (vendor name, model name, machine number, etc.) included in the abnormality detection data is displayed on the display screen of the monitoring terminal device 210 (panel alarm screen). . Then, in the panel configuration diagram, the panel portion specified by the abnormal panel information included in the abnormality detection data has an alarm color (for example, red).

For example, when the three panels 20 to 22 of the base station of the vendor A become abnormal, for example, as shown in FIG. 15, the panel 20 corresponds to the panels 20 to 22 of the baseband section B2 in the panel configuration diagram. The part turns red. Vendor B
In the case where the panel 2 of the base station of
As shown in, in the panel configuration diagram, the portion of the baseband portion B2 corresponding to the panel 2 is red. When the panels 25, 26, 28, 29 of the base station of the vendor C become abnormal, for example, as shown in FIG. 17, in the panel configuration diagram, the panels 25, 26, 26 of the baseband unit B2,
The portions corresponding to 28 and 29 are red.

By looking at the alarm screen displayed on the monitoring terminal device 210 according to such abnormal part display control, the maintenance person can know the specific panel in which the abnormality has occurred, restart the panel, or Maintenance work such as replacement can be performed.

As shown in FIGS. 15, 16 and 17, the alarm screens corresponding to the base stations of different vendors are different even if the same baseband unit is abnormal. Therefore, if the maintenance person does not understand the hardware configuration of the base station of each vendor, it is difficult to immediately understand which part has a failure from the alarm screen. This tendency becomes stronger as the number of vendors increases. Further, it is difficult to immediately know how the abnormality of the panel affects the communication service only from the abnormal panel portion which can be known from the alarm screen as described above.

Therefore, the monitoring server 200 performs the function block display control and causes the monitoring terminal device 210 to display the following graphical function block warning screen.

When it is recognized that the equipment in which an abnormality has occurred is the base station based on the model information included in the abnormality detection data, the alarm area corresponding to each functional block of the base station is shown in FIG. 18, for example. So that the monitoring terminal device 210
Is displayed on the display screen of (Function block alarm screen). That is, in the monitoring system, the RF unit, the receiving unit, the RNC connection unit, the power supply unit, the baseband unit and the sector are defined as the functional blocks of the base station (FIG. 1).
2), this functional block alarm screen has an alarm area corresponding to each functional block.

Then, based on the abnormal block information and the alarm level information included in the abnormality detection data, the alarm area of the functional block specified by the abnormal block information becomes the alarm level specified by the alarm level information. The corresponding alarm color is displayed. The example shown in FIG. 18 shows a case where an abnormality occurs in the functional block of the baseband unit (BB unit), and the alarm area corresponding to the baseband unit has a color corresponding to the alarm level.

For example, as shown in FIG. 15, when the panels 20 to 22 of the base station of the vendor A become abnormal, and when the panel 2 of the base station of the vendor B becomes abnormal as shown in FIG. When the panels 25, 26, 28 and 29 of the base station of the vendor C become abnormal as shown in FIG. 17, the alarm level of all the baseband functions becomes the alarm H (High-ALM) (shown in FIG. 14). Alarm mapping table). Therefore, when an abnormality occurs in the base station of each vendor as shown in FIG. 15, FIG. 16 and FIG. 17, the alarm area of the baseband unit is always an alarm H (High-ALM) as shown in FIG.
The color corresponds to the alarm level of.

As described in the alarm mapping table shown in FIG. 14, the normal display color is
Green, alarm L (Low-ALM) display color is orange, alarm H (High-ALM)
The display color of ALM) is purple, and the display color of failure alarm (System-ALM) is red.

As described above, the maintenance person can know the abnormal function block by looking at the function block alarm screen displayed on the monitoring terminal device 210 according to the function block display control. In this way, by knowing the functional block that has become abnormal, it becomes possible to immediately understand the failure situation in the base station, the effect that abnormality has on the communication service, measures for network management etc. without delay, for example, It becomes possible to regulate outgoing / incoming calls, restart the entire device (when the base station (equipment) is effectively unavailable), and so on.

Further, since the alarm area corresponding to the functional block in which the abnormality has occurred has a color corresponding to the alarm level indicating the degree of the abnormality, the maintenance person can immediately judge the degree of abnormality in the functional block. Furthermore, it is possible to easily determine the effect of the abnormality on the communication service.
