Description

[0001] WIRELESS NETWORK EQUIPMENT AND METHOD FOR MANAGING NETWORK BY USING THE EQUIPMENT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless network device and a network management method using the device, and more particularly, to a wireless network device that communicates with a server wirelessly and a network management method using the device.

Recently, as a wireless communication environment such as a WCDMA / LTE environment is established, the spread of network devices for realizing a wireless network environment is becoming active.

In recent years, a network management system for managing the status of network devices has also been popular. For example, a server can access a network device to check the status of the network device for network management.

That is, for example, a Simple Network Management Protocol (SNMP) agent and an SNMP manager can be installed and operated on the network. Accordingly, the server in which the SNMP manager is installed may transmit a ping to the network device according to an ICMP (Internet Control Message Protocol) and determine whether the network device has failed according to the response of the network device to the ping.

However, in such a network management system based on SNMP, it is assumed that the communication is a wired communication when the server and the network device communicate with each other.

Therefore, the network management system as described above may be a problem when the network device and the server communicate according to the WCDMA / LTE environment.

That is, it is difficult for a network device in a WCDMA / LTE environment to have a static IP depending on characteristics of a WCDMA / LTE environment, and it is difficult for the server to search for and access the network device even though the static IP is available. As a solution to this, if the server and the network device are continuously connected, the cost of the WCDMA / LTE environment is constantly charged, which causes excessive cost and wastes system resources.

Also, due to the characteristics of the WCDMA / LTE environment, continuous connection between the server and the network device is difficult, and therefore, the server is likely to recognize that a normal network device has failed, . Since it is difficult to accurately diagnose the network device, there is a problem that the network management can not be efficiently performed. Therefore, a technique for solving the above-described problems is required.

Prior art document No. 1996-0025103 relates to an SNMP agent function as an additional function of an Ethernet local bridge and more particularly to a method of implementing an SNMP agent function in a local bridge and is connected to a LAN interface unit for transmitting and receiving a packet A reception step of receiving a packet received from the LAN interface unit, which is operated on a RISC system having a RISC CPU for overall operation control, a packet analysis step of determining a protocol type of the received packet, An SNMP message decryption step of decrypting the received SNMP message, an SNMP message processing step of processing the decrypted message according to the specified SNMP protocol, an SNMP message encoding step of encoding the SNMP message to be transmitted, Including a transmitting step, That operates in the local bridge for sending and receiving characterized.

That is, although the prior art document describes a method for implementing the SNMP agent function in the local bridge, it does not recognize the above-described problem, nor does it describe a method for solving the above-described problem.

On the other hand, the background art described above is technical information acquired by the inventor for the derivation of the present invention or obtained in the derivation process of the present invention, and can not necessarily be a known technology disclosed to the general public before the application of the present invention .

The network device 20 is a device that is disposed in a network for connecting between a user terminal 10 (or a network 30) and a server 40. The network device 20 is, for example, a hub, a bridge, , A switch or router, and the like. In particular, the wireless network device according to an embodiment of the present invention refers to a device connected to a server wirelessly, and an agent implementing a network management method according to an embodiment of the present invention may be installed.

One or more such network devices 20 may be present in the network management system 100 and such network devices 20 will be described in more detail below with reference to FIG.

Meanwhile, the server 40 may be a server that provides a service to the user terminal 10, for example, a server on which a server program for a client program installed in the user terminal 10 is being executed. The server 40 may be implemented, for example, as a conventional web server (or mobile web server) that accepts a web connection from the user terminal 10, but the server 40 is not limited to the example described above.

In addition, the server 40 may determine whether the wireless network device has failed based on the access time information of the wireless network device.

That is, the server 40 can receive the access time information from the wireless network device, determine whether or not the wireless network device has a failure according to whether or not the time when the wireless network device accesses the server matches the access time information can do.

For example, when receiving from the wireless network device, the server 40 receives 10 seconds as the access time information, 10 seconds after the most recent access time of the wireless network device (or 10 seconds after the most recent access time) If the wireless network device can not detect the access of the wireless network device during a predetermined period of time (e.g., a predetermined period of time).

Then, the server 40 generates update information for the wireless network device determined to have a failure, or generates a control command for rebooting the wireless network device, and transmits the update information or control command to the wireless network device .

2 is a block diagram illustrating a wireless network device 20 in accordance with an embodiment of the present invention.

The wireless network device 20 may include a data collection unit 210, an access unit 220, an update unit 230, and a control unit 240, as shown in FIG.

The wireless network device 20 includes a communication unit (not shown) that enables communication between internal components, that is, the data collecting unit 210, the access unit 220, the update unit 230, and the control unit 240, As shown in FIG. The communication unit (not shown) may enable communication between the wireless network device 20 and an external component, and may communicate with the user terminal 10 or another network device through a wired / wireless network , And the server 40 through a wireless network.

The data collecting unit 210 included in the wireless network device 20 is configured to collect device information of the wireless network device.

Here, the equipment information is information necessary for the wireless network device to normally operate in the network. For example, the equipment information may include a CPU usage amount, a memory usage amount, a reception (or transmission) packet capacity (for example, Number of packets).

On the other hand, the access unit 220 is configured to allow the wireless network device 20 to access the server 40.

For this, the access unit 220 can calculate the access time information by calculating the time when the wireless network device 20 transfers the device information to the server 40.

Herein, the 'access time information' may be information on the time when the wireless network device will connect to the server, information on the server access period, or information on a specific time when the server accesses the server.

The access unit 220 can calculate the cost that can be generated per packet and determine the packet capacity that can minimize the cost per packet when determining the packet capacity in the wireless communication environment. The access unit 220 can calculate the access time information according to the determined packet capacity.

Therefore, the access unit 220 can periodically access the server 40 based on the access time information generated as described above.

The access unit 220 may also provide the access time information to the server 40 when the server 40 is accessed.

Then, the access unit 220 can detect that the wireless network device 20 is in an abnormal state. Accordingly, if the wireless network device 20 detects that it is in an abnormal state, it can access the server 40 to perform a solution to the abnormal state.

If the access unit 220 confirms that the server has been accessed, the access unit 220 can transmit the equipment information collected by the data collection unit 210 to the server 40. [

In addition, the access unit 220 can stop the access to the server. For example, if the access unit 220 confirms that the provision of the equipment information to the server is completed, the access unit 220 can stop the access to the server. Also, if the access unit 220 confirms that there is no update information on the server, the access unit 220 can stop the access to the server.

On the other hand, the update unit 230 is configured to perform update of the network device upon receiving the update information.

To this end, the update unit 230 may collect update information on the server while accessing the server.

Here, the update information is information for maintaining or updating the state of the wireless network device, for example, updating the access method with the server, updating the collection method of the equipment information, rebooting the network device, Information on addition, deletion, etc. of information.

In other words, the update unit 230 may perform the update based on the collected update information.

Meanwhile, the control unit 240 may be configured to control the data collecting unit 210, the access unit 220, the updating unit 230, and the control unit 240.

In addition, the control unit 240 can receive a control command, such as a forced termination or a reboot, from the server 40, and can operate the wireless network device 20 according to the control command.

Also, when receiving the control command (or update information), the control unit 240 can verify whether the received control command (or update information) is received from the authorized server, When the control command (or update information) is received from the server having no control authority, the control command (or update information) can be ignored.

As shown in FIG. 3, the wireless network device 20 may collect device information (S310).

At this time, the wireless network device 20 can generate the access time information and continuously collect the equipment information based on the access time information (S320).

That is, the network device 20 can access the server when the access time to the server 40 is based on the access time information (S330). If the network device 20 detects that a failure has occurred, the network device 20 can access the server (S330).

The network device 20 accessed by the server 40 may provide the collected device information to the server (S340).

Then, the network device 20 can search whether the server 40 includes update information for the network device 20 (S350).

If the search result update information exists, the network device 20 collects the update information (S360), and may perform the update of the network device 20 according to the collected update information (S370).

On the other hand, the server 20 that has detected the access of the network device 20 through the above-described process can receive the equipment information from the network device 20.

At this time, the server 40 may determine whether the network device has failed based on the maintenance information, or may generate update information for the network device.

On the other hand, the server 40 can receive the access time information from the network device (S410), as shown in FIG. 4, and determines whether or not the device information is received at the access time determined based on the access time information , Whether the network device has accessed) (S420).

According to the determination result, the server 40 can determine whether or not the network device 2 has failed.

That is, the server can determine that the network device has a failure when the access time of the wireless network device is not the predetermined time based on the access time information (S430). For example, if the network device is set to access at 16:00 every day, if the network device does not access at 16:00, it can determine that the network device has a failure.

On the other hand, if the server detects that the wireless network device has accessed the predetermined access time based on the access time information, it may determine that the network device is not obstructed (S440).

The network management method according to the embodiment described with reference to Figs. 3 to 4 may also be implemented in the form of a recording medium including instructions executable by a computer, such as program modules, being executed by a computer.
