Description

  The present invention relates to a management apparatus that manages installation, relocation / removal of a monitoring target device such as a radio base station, and a monitoring target device management method.

Conventionally, when installing a wireless base station that is a monitored device, the network management server automatically filters the monitored device by using ICMP (Internet Control Message Protocol) / SNMP polling and filtering on the network management application side. In particular, a technique for registering as a managed object is known (for example, see Patent Document 1). The registration function according to this prior art is based on the premise that the IP address of the monitoring target device exists in advance, and the information to be automatically displayed on the map is limited to the network hierarchy diagram.

  By the way, wireless base stations are scattered and installed in a wide range. However, the conventional technique has a problem that it is necessary for an operator to set an IP address or the like for each wireless base station or network management server, and the work becomes complicated. In addition, in the case of a radio base station, there is a problem that management objects to be automatically displayed on a map can be expressed only on a network basis, although the association with geographic information is more important than the network hierarchy. In addition, when moving / removing a radio base station, there is a problem that the information on the network management server side cannot be synchronized with the actual completion of the relocation / removal operation.

  The present invention has been made in consideration of such circumstances, and the object thereof is to reduce the complexity of installation, relocation, and removal work of a radio base station, as well as actual work and a network management server. It is intended to provide a monitoring target device management method, a monitoring target device management system, and a monitoring target device management server that can be synchronized with geographic information and can be easily associated with geographic information.

In order to solve the above-described problems, the following means were adopted.
Management apparatus according to the present invention is a management apparatus for managing the monitored device, the identification information holding means for holding identification information to be assigned to the monitoring target device, control the allocation of the identification information to the monitoring target device comprising identification information managing means for the said identification information management means, on the basis of the request from the monitoring target device with the installation of the monitored equipment, the monitoring target device that the request, expiration date When the monitoring target device to which the identification information with the infinite validity period is assigned is removed from the current installation position, the monitoring target device to be removed is assigned to the monitoring target device. The same identification information as the identification information with an infinite expiration date is set and reassigned with an expiration date set .

Further, the identification information management means, when receiving a predetermined signal from the monitoring target device before the expiration date has passed is characterized by extending the expiration date.

Monitored device management method according to the present invention is a monitoring target device management method for managing the monitored device by the management device, before Symbol management device, a request from the monitoring target device with the installation of the monitoring target device And assigning the identification information with an indefinite expiration date to the monitoring target device that has made the request, and the monitoring target device to which the identification information with the infinite expiration date is assigned from the current installation position Including the step of setting and reassigning the same identification information as the identification information with an infinite expiration date to the monitored device to be removed when the device is to be removed. To do.

  According to this invention, when the monitoring target device is installed, identification information in the network having an indefinite lease period for identifying the monitoring target device based on a registration request from the monitoring target device Is assigned to the monitored device, and when the monitored device is relocated or removed, the in-network identification information already assigned to the monitored device is reassigned with a predetermined lease period, and the monitored device When the predetermined lease period elapses after the intra-network identification information is reassigned, the already-assigned intra-network identification information is updated to unassigned. Therefore, it is possible to reduce the complexity of the installation, relocation, and removal work of the radio base station, and to obtain an advantage that the actual work and the information on the network management server side can be synchronized.

  Moreover, according to this invention, the positional information which shows the installation place of the said monitoring object apparatus is acquired, and the installation place of the said monitoring object apparatus is displayed on map information based on the said position information so that visual recognition is possible. Therefore, there is an advantage that installation, relocation, and removal of a radio base station can be easily associated with geographical information.

  Further, according to the present invention, when the monitoring target device is moved or removed, when the predetermined signal is received from the monitoring target device before the predetermined lease period elapses, the predetermined lease period Is extended. Therefore, there is an advantage that it is possible to flexibly cope with a delay in the installation, relocation, and removal work of the radio base station.

  Further, according to the present invention, when the monitoring target device is installed by the identification information allocating means, the management apparatus can identify the monitoring target device based on the registration request from the monitoring target device. While the in-network identification information having the lease period is assigned to the monitored device, when the monitored device is moved or removed, the in-network identification information already assigned to the monitored device is assigned with a predetermined lease period. When the predetermined lease period elapses after the intra-network identification information is re-assigned by the re-assignment and identification information update means, the already-assigned intra-network identification information is updated to unassigned. Therefore, it is possible to reduce the complexity of the installation, relocation, and removal work of the radio base station, and to obtain an advantage that the actual work and the information on the network management server side can be synchronized.

  Further, according to the present invention, the management device can visually recognize the installation location of the monitoring target device based on the position information of the monitoring target device acquired by the position information acquisition unit of the monitoring target device by the display control unit. Display. Therefore, there is an advantage that installation, relocation, and removal of a radio base station can be easily associated with geographical information.

  Further, according to the present invention, when the monitoring target device is moved or removed by the lease period extension means, the management device receives a predetermined signal from the monitoring target device before the predetermined lease period elapses. Will extend the predetermined lease term. Therefore, there is an advantage that it is possible to flexibly cope with a delay in the installation, relocation, and removal work of the radio base station.

  Hereinafter, a monitoring target device automatic management system according to an embodiment of the present invention will be described with reference to the drawings.

A. Configuration of Embodiment FIG. 1 is a block diagram showing a configuration of a monitoring target device automatic management system according to an embodiment of the present invention. In the figure, wireless base stations 1-1 to 1-n are installed in a wide range and function as GPS processing units 2-1 to 2-n and DHCP clients for acquiring their own geographical positions. DHCP client processing units 3-1 to 3-n. The router 4 has a DHCP relay agent function. The router 5 connects the radio base stations 1-1 to 1-n to the radio base station management server 6 via a network (not shown).

  The radio base station management server 6 manages the installation, relocation / removal states of the radio base stations 1-1 to 1-n, and includes a DHCP server 6-1 and an SNMP manager 6-2. The DHCP server 6-1 automatically distributes IP addresses and the like to the radio base stations 1-1 to 1-n. The SNMP manager 6-2 maintains the installation and relocation / removal states of the radio base stations 1-1 to 1-n, and displays the radio base stations as icons on the map displayed on the display device.

B. Operation of Embodiment Next, the operation of the above-described embodiment will be described.

(1) Installation of Radio Base Station Operation FIG. 2 is a timing chart for explaining the operation at the time of installation of the radio base station operation in the monitored device automatic management system according to the present embodiment. First, in order to attach the radio base station 1-i (i = 1 to n) to a predetermined place, the worker turns on the power after construction and installation (Sa1). When the wireless base station 1-i is turned on, the wireless base station 1-i starts up as a DHCP client and transmits a DHCP DISCOVERY to the DHCP server 6-1 via the DHCP relay agent 4, thereby obtaining an IP address, other An acquisition request for setting information is made (Sa2). At this time, the SNMP manager 6-2 is activated. At this time, a default value is used for SNMP Read Community / Write Community.

  When receiving the acquisition request, the DHCP server 6-1 distributes the IP address, subnet mask, and default gateway from the pre-registered address pool to the radio base station 1-i with an indefinite lease period (Sa3). . At this time, the IP address is registered in the address pool and other setting information is also transmitted. When receiving the DHCP ACK for the DHCP REQUEST from the radio base station 1-i, the DHCP server 6-1 notifies the SNMP manager 6-2 of the IP address and subnet mask leased from the address pool (Sa4).

  Next, the SMNP manager 6-2 acquires “MIB-II.system.sysDescr” and the like from the radio base station 1-i according to the IP address notified from the DHCP server 6-1 (SNMP GET: Sa5). Then, it is determined whether or not the IP address leased from the address pool is a radio base station to be monitored (Sa6). The “MIB-II.system.sysDescr” is a field indicating the type (client information) of the device for which the IP address is leased. If the wireless base station is a monitoring target, the wireless base station 1-i is restarted (Sa7). When the radio base station 1-i restarts, the GPS processing unit 2-i acquires GPS information (Sa8), saves it in a private MIB (Management Information Base) (Sa9), and completes the GPS information acquisition completion by the SNMP manager 6 -2 (SNMP TRAP: Sa10).

  Next, when receiving the GPS information acquisition completion (SNMP GET), the SNMP manager 6-2 acquires the GPS information from the radio base station 1-i (SNMP GET: Sa11). The SNMP manager 6-2 stores the GPS information in order to register the wireless base station 1-i as a new management object (Sa12), and the wireless base station 1 on the map displayed on the display device according to the GPS information. An icon indicating -i is displayed (Sa13).

  According to the present embodiment, it is not necessary to dispatch a field engineer who has knowledge and skills related to the network in order to set the radio base stations 1-i that are installed in a wide range. Further, it is not necessary to manually add an entry to the radio base station management server 6 and it is not necessary to manually register the radio base station management server 6 on the map. That is, the complexity of installation work of the radio base station 1-i can be reduced, and the actual work state can be synchronized with the management information on the radio base station management server 6 side. Can be associated with

(2) Transfer / Removal of Radio Base Station Operation Next, FIG. 3 is a timing chart for explaining operations at the time of transfer / removal of a radio base station operation in the monitoring target device automatic management system according to the present embodiment. First, when an operator issues an instruction to move / remove a monitoring target entry from an icon indicating a wireless base station on the GUI application of the SNMP manager 6-2 (Sb1), the SNMP manager 6-2 has deleted the entry. This is notified to the DHCP server 6-1 (Sb2). At this time, the corresponding icon visually expresses that it is relocation / removal.

  When the DHCP server 6-1 receives the relocation / removal notification of the monitoring target entry from the SNMP manager 6-2, the DHCP server 6-1 sets the corresponding IP address to the relocation / removal state (Sb3), and sends a DHCP FORCERENEW message to the corresponding radio base station 1-i. Transmit (Sb4). Upon receiving the DHCP FORCERENE message, the radio base station 1-i immediately starts reconfiguring the IP address (Sb5). At this time, the DHCP server 6-1 makes the lease period of the IP address finite (several hours) (Sb6).

  More specifically, when receiving the DHCP FORCERENEW message, the radio base station 1-i transmits DHCP DISCOVER to the DHCP server 6-1. The DHCP server 6-1 redistributes the same IP address to the radio base station 1-i with a finite lease period when the source IP address of the received DHCP DISCOVER matches the IP address that has been moved / removed. To do. At this time, the reconfiguration period is set shorter than the lease period. Thus, before the relocation / removal is completed, the wireless base station management server 6 monitors the same IP address when the wireless base station 1-i is powered on (while it is activated as a DHCP client). It becomes possible to continue doing.

  Then, the operator performs the relocation / removal operation of the radio base station 1-i on site, and the power is turned off (Sb7). The DHCP server 6-1 determines whether or not the elapsed time from the redistribution of the IP address has passed for the lease period (Sb8), and when the lease period has passed, returns the IP address to the address pool. (Sb9). In addition, the fact is notified to the SNMP manager 6-2 (Sb10). If the wireless base station 1-i transmits a predetermined signal to the DHCP server 6-1 within the lease period, the DHCP server 6-1 extends the lease period by a predetermined time. This is to allow the operator to extend the lease period when the relocation / removal work is longer than planned.

  Upon receiving the IP address return notification, the SNMP manager 6-2 deletes the IP address from the monitoring target entry (Sb11). Thereby, also in the radio base station management server 6, the radio base station 1-i is moved / removed.

  According to this embodiment, it is possible to visually monitor the Chinese poetry object from the radio base station management server 6 by instructing the radio base station management server 6 to move / remove the radio base station 1-i. Also, entry deletion is automatically determined by setting a predetermined lease period for the entry of the IP address instructed as the relocation / removal state and using the DHCP reconfiguration function of the radio base station 1-i. Can do. That is, it is possible to reduce the complexity of the relocation / removal work of the radio base station 1-i, and to synchronize the actual relocation / removal work and the management information on the radio base station management server 6 side.

  In the embodiment described above, a series of processing steps performed by the wireless base stations 1-1 to 1-n, the wireless base station management server 6 and the like are stored in a computer-readable recording medium in the form of a program. The above processing is performed by the computer reading and executing this program. That is, each processing means and processing unit in the radio base stations 1-1 to 1-n, the radio base station management server 6 and the like are processed by a central processing unit such as a CPU in the main storage device such as a ROM and a RAM. It is realized by reading and executing information processing / calculation processing.

  Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.
