Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management device and a management system for managing whether or not a subordinate device such as a mobile communication device is operating normally.

[0002]

2. Description of the Related Art Conventionally, a personal handy phone (Personal Han
dyphone System: Hereinafter referred to as "PHS". ) Network management system (Ne
twork Management System: Hereinafter referred to as "NMS". ) Manages whether several 1000 to several 10,000 wireless base stations are operating normally.

NMS is the above-mentioned several thousand to several thousand.
It manages whether the registered wireless base stations among the 0 wireless base stations are operating normally. That is, the radio base station is under the jurisdiction of the NM in order to be managed by the NMS.
It must be registered in S beforehand.

Here, when a failure occurs in the radio base station,
The wireless base station transmits an autonomous message storing its own identifier and failure content to the NMS. NMS
Receives it and determines whether or not the wireless base station which is the source of the autonomous message is registered in the NMS.

As a result of the judgment, when the radio base station is registered in the NMS, the content of the failure is detected from the autonomous message and the manager is notified. The administrator thereby recovers the failure of the radio base station. On the other hand, if the radio base station is not registered with the NMS, the NMS discards the autonomous message.

[0006]

However, in order for the radio base station to be managed by the NMS, the radio base station to be managed must be registered in the NMS. This registration is performed by the NMS administrator. It was registered manually one by one. Therefore, since this registration work is required before the wireless base station is operated under the control of the NMS, enormous time and labor have been spent.

When the radio base station is not registered in the NMS, the autonomous message is discarded as described above. Therefore, even if the wireless base station in which a failure has occurred transmits an autonomous message to the NMS, the NMS cannot notify the administrator of the failure, and the failure in that wireless base station is not repaired.

[0008] Therefore, an object of the present invention is to allow an NMS to manage a lower-level device such as a radio base station without registration by an administrator.

[0009]

In order to solve the above-mentioned problems, the present invention provides a management device which is connected to a plurality of lower devices and manages the operation of the plurality of lower devices. Receiving means for receiving a notification, which is transmitted from the faulty lower-level device and stores the content of the fault and an identifier for identifying the faulty lower-level device from other lower-level devices, and the received notification. Detecting means for detecting the sender of the notification from the identifier stored in the identifier, judging means for judging the presence or absence of registration of the lower device which is the sender of the notification, and the result of the judgment, transmission of the notification Registration means for registering the lower-level device when the original lower-level device is not registered; and, as a result of the determination, when the lower-level device which is the transmission source of the notification is registered or after the registration, the fault Of And a notifying means for notifying a.

Further, a management system of the present invention comprises the above-mentioned management device and a plurality of lower-level devices managed by the management device to determine whether or not they are operating normally.

[0011]

FIG. 1 is a diagram showing a PHS network. In FIG. 1, 11 to 1n are radio base stations,
Reference numeral 30 is a network management system (NMS), and 20 is a network network that connects a plurality of exchanges (not shown) that connect the radio base stations 11 to 1n and the NMS 30. The actual PHS network includes a plurality of network networks (not shown) and a plurality of radio base stations.

When the radio base stations 11 to 1n are installed and operated, a link is established between the radio base stations 11 to 1n and the NMS 30 via the network 20 and a plurality of exchanges (not shown). The radio base stations 11 to 1n each send an autonomous message to the NMS 30 via a link.

In this specification, "autonomous message"
Means a notification that, when a failure occurs in the wireless base station, the wireless base station transmits the failure content to the NMS 30. In addition, an identifier such as a unique CS number assigned to each radio base station can be stored in the header portion of the autonomous message, and the radio base station having a failure can be stored, for example, in a unique identifier assigned to itself. Store and send the CS number. The NMS 30 receives the autonomous message thus transmitted.

FIG. 2 is an internal block diagram of the NMS 30.
In FIG. 2, 1 is a connection unit having a gateway function,
Reference numeral 2 is a determination unit that determines whether or not the wireless base station that is the transmission source of the autonomous message output from the connection unit 1 is registered in the NMS 30 body and determines the output destination of the autonomous message based on the presence or absence of registration. .

Further, 3 is, for example, the radio base stations 11 to 1n.
Is a configuration management unit that manages the registration presence / absence information of the wireless base stations 11 to 1n, including a table that stores the registration and the presence or absence of registration. The configuration management unit 3 registers the wireless base station which is the transmission source of the autonomous message, when the wireless base station is not registered in itself.

It should be noted that the NMS 30 stores in advance an identifier such as a CS number of a wireless base station to be managed, and when an autonomous message transmitted from a wireless base station not originally under the control of the NMS 30 is received, it is different from the conventional one. Similarly, the autonomous message is discarded.

Here, the registration process is usually performed by the administrator operating an input means such as a keyboard (not shown) before operating the NMS 30. Specifically, when the administrator performs an operation for registering a wireless base station, a predetermined registration process is performed, and “unregistered” in the table of the configuration management unit 3 becomes “registered”. Further, as will be described later, when the NMS 30 side receives an autonomous message transmitted from a wireless base station, and the wireless base station is not registered in the configuration management unit 3, the registration process is the same as above. Done.

Reference numeral 4 denotes a fault management unit that detects the content of the fault from the autonomous message of each of the radio base stations 11 to 1n output from the determination unit 2 and displays the detection result on the display unit 6.

Further, 5 indicates the position of the registered wireless base station by lighting a symbol on the map display portion 7, and blinks the position of the wireless base station of the sender of the autonomous message as a symbol on the map 7. It is a hierarchy map section. The map display unit 7 notifies the administrator of the NMS 30 by, for example, lighting / blinking the location of the managed wireless base station and the location of the defective wireless base station.

The NMS 30 may be composed of software or hardware. Further, for example, the map display unit 7 may be deleted, and the display unit 6 may be changed to display the hierarchical map by an operation of the administrator of the NMS 30.

FIG. 3 is a diagram showing a specific example of the detection result of the autonomous message displayed on the display unit 6. As shown in FIG. 3, the detection result displays, for example, "fault occurrence date and time", "device name", "fault content", and "CS number". The “fault occurrence date and time” is the time when the connection unit 1 of the NMS 30 receives the autonomous message. In addition, "device name" is NMS
The name is assigned to 30, and is given, for example, a region name.

4 (a) to 4 (c) are diagrams showing a hierarchical map displayed on the map display section 7. FIG. 4 (a) is a map of Japan, FIG. 4 (b) is a map of Kanto, and FIG. c) is a map of Tokyo. In FIGS. 4A to 4C, a circle mark indicates a radio base station. 4A to 4C show the NMS 30.
The display contents can be changed by the operation of the administrator of.

FIG. 5 is a flow chart showing the operation of the NMS of this embodiment. The operation of the NMS of the present embodiment will be described on the assumption that a failure occurs in the radio base station 11.

After a link is established between the radio base stations 11 to 1n and the NMS 30, for example, when a fault occurs in the radio base station 11, the radio base station 11 uses, for example, as a content of the fault and an identifier. An autonomous message storing the unique CS number is transmitted to the NMS 30.

The NMS 30 receives this autonomous message by the connection unit 1 (step S1). Connection 1
Is the wireless base station 11 that is the source of the autonomous message.
Outputs the autonomous message to the determining unit 2 regardless of whether or not it is registered in the registration unit of the configuration management unit 3. In addition, in the present embodiment, as described above, the time when the autonomous message is received by the connection unit 1 is regarded as the time when the failure occurs in the wireless base station 11.

As described above, the connection unit 1 outputs the received autonomous message to the determination unit 2 without checking whether or not the wireless base station 11 which is the transmission source of the received autonomous message is registered in the registration unit. Therefore, even if the wireless base station 11 is not registered, the autonomous message is not discarded.

When the autonomous message is input, the decision unit 2 extracts the CS number of the wireless base station 11 stored in the header portion of the autonomous message. Then, it is determined from the table provided in the configuration management unit 3 whether or not the wireless base station 11 is registered (step S2).

If the wireless base station 11 is registered, the process proceeds to step S3, and an autonomous message is output to the fault management unit 4. On the other hand, if it is not registered,
In step S4, in order to register the wireless base station 11, an autonomous message is output to the configuration management unit 3 as a registration request.

When the autonomous message, which is a registration request, is input from the determining unit 2, the configuration managing unit 3 extracts the unique CS number of the wireless base station 11 from the header portion of the autonomous message and performs the registration process. When the registration process of the wireless base station 11 is performed, the autonomous message is output to the failure management unit 4.

When the wireless base station 11 is registered, the symbol corresponding to the wireless base station 11 is newly installed on the map.
Outputs a notification that registered. The operation of the hierarchy map unit 5 after inputting this notification will be described later.

When the autonomous message is input from the determining unit 2 or the configuration managing unit 3, the fault management unit 4 determines what type of fault is occurring in the radio base station 11 from the information stored in the autonomous message. To analyze. Then, the analysis result is output to the display unit 6. The display unit 6 displays the analysis result as shown in FIG. 3, for example.

The fault management unit 4 also outputs to the hierarchy map unit 5 a control signal for blinking the symbol of the radio base station 11 that is lit on the map 7. The hierarchy map section 5 is
When the control signal is input, the symbol of the wireless base station 11 displayed on the map display unit 7 is turned on. The symbol may be displayed by changing the color depending on, for example, whether a failure has occurred or not.

As described above, the PHS according to the embodiment of the present invention.
Although the case where the network is managed by the NMS 30 has been described, the target managed by the NMS is not limited to the PHS network, but may be a mobile communication device such as a cellular phone or a pager and other lower devices. It does not matter if it is managed.

[0034]

As described above, according to the present invention, it is determined whether or not the source of the notification transmitted due to the occurrence of a failure is under the control of the NMS, and as a result of the determination, the source of the notification is managed. If it is not under control, it is registered to be under control, and as a result of the determination, if the transmission source of the notification is under control or after registration, the content of the failure is notified.

Therefore, the labor for the administrator to register the lower device in the NMS is eliminated. Further, it is possible to substantially manage the lower-level devices that are not registered in the NMS until the time of notification.
