Accordingly, the need for a monitoring device capable of monitoring and controlling a large amount of equipment is increasing.

1 is a view for explaining a failure handling method for a transmission device in the conventional network operation.

The transmission equipment shown in FIG. 2 is communication equipment installed in the electric poles, walls, apartments, buildings, etc. of each remote site, and there should be no breakdown for the best network operation, and if a breakdown occurs, it should be able to recover it quickly. Conditions must be established that must be fast.

Of these, in order to satisfy the conditions of speed, it is possible to supply and receive data by supplying new equipment, but this also leads to an increase in equipment, and eventually, a necessity of thorough management of equipment maintenance and repair is emerging.

By the way, according to the prior art, the central management center (1) received this and solved the problem of disability by a telephone call with the person in charge, and if not solved in this way, the person in charge is sent to the site directly to check the transmission equipment It was done in the form of.

As such, in the related art, it is impossible to remotely determine the cause of the failure without the person in charge directly dispatching to the site, and furthermore, the remote control is impossible.

However, compared to the number of subscribers and the number of subscribers using the Internet, there is a problem that the working staff is inadequate, and the working staff directly delays the time of dispatching to the field, making it difficult to immediately process. In particular, if it is not a simple obstacle, the practitioner has to collect and process the transmission equipment, which inevitably causes a time delay, thereby increasing the inconvenience for the user.

In addition, there is a problem that the fundamental measures of the occurrence of disability is impossible when the person in charge of the work leave the working place, such as holiday or night.

Accordingly, the present invention has been made to solve the above problems, and the technical problem is to enable the remote monitoring and control even if the operator does not visit the remote transmission equipment directly.

Transmission equipment emergency recovery system using a CDMA wireless network according to the present invention for achieving the above technical problem, a plurality of transmission equipment; A plurality of fault diagnosis terminals for performing serial communication to the plurality of transmission devices; A network management center wirelessly connected to the plurality of fault diagnosis terminals to receive and check state information regarding the plurality of transmission devices, and remotely recover an emergency when a failure event occurs in the plurality of transmission devices; And a CDMA network for performing wireless communication between the plurality of fault diagnosis terminals and the network management center.

According to an example of the present invention, the plurality of transmission equipments may include any one or more of a digital subscriber line access multiplexer (DSLAM), a fiber to the home (FTTH), an optical home LAN, a concentrator, and an FES.

According to an example of the present invention, the plurality of fault diagnosis terminals may perform serial communication with the plurality of transmission devices.

In this case, the plurality of fault diagnosis terminals may correspond one-to-one with the plurality of transmission equipment.

Alternatively, the plurality of transmission equipments may correspond to the one failure diagnosis terminal. In this case, the one fault diagnosis terminal may further include a multi-expansion pack for controlling the plurality of transmission equipment.

According to an example of the present invention, the network management center collectively manages location information on the plurality of transmission equipments and the failure diagnosis terminals corresponding to each of the plurality of transmission equipments, and the plurality of transmissions received from the end of the failure diagnosis. A distribution server configured to store state information of the transmission equipment of the database; It may include a diagnostic server for analyzing and diagnosing the cause of the failure event by analyzing the state information for the plurality of transmission equipment received from the terminal of the plurality of failure diagnosis.

According to an example of the present invention, the transmission equipment that is the object of diagnosis may be connected to the interface one by one.

According to another example of the present invention, a plurality of transmission equipment that is the object of diagnosis may be connected to the interface. In this case, a multi-expansion pack for controlling the plurality of transmission devices may be further included between the transmission device and the interface.

On the other hand, the transmission equipment emergency recovery method using a CDMA wireless network according to the present invention for achieving the technical problem, (a) remotely monitoring the transmission equipment provided in a remote location via a failure diagnosis terminal; (b) communicating with the failure diagnosis terminal using a CDMA network when a failure event occurs in the transmission equipment; (c) receiving status information of the transmission equipment from the failure diagnosis terminal to analyze and check the cause of the failure event; (d) performing recovery by transmitting the recovery control command to the failure diagnosis terminal when recovery of the failure event is required; And (e) after the restoration is completed, storing a log file in the network management center and disconnecting from the CDMA network.

According to the present invention described above, even if a person in charge is not directly dispatched to a remote device, since it is possible to monitor and control the equipment at a remote location, it is efficient in terms of work environment and efficiency, and remotely regardless of time and place even when a failure occurs. Emergency recovery is possible, so the immediate effect is possible.

In addition, by controlling the CDMA network with proven stability, not only can network quality be improved, but also stability and durability can be secured.

The present invention uses a Code Division Multiple Access (CDMA) wireless network for fast state identification and remote control. The CDMA wireless network has the following features.

1) High quality service is available.

In the analog approach, signals coming in multiple paths have a significant adverse effect on the call. However, the CDMA network separates these multipath signals and selects a good signal, so that the quality is better than the analog method, and the quality of communication is good because it uses a soft handoff method without disconnection of a call during handoff.

2) Large capacity.

The same frequency can be used in many cells, with less interference than other methods, and the transmission capacity can be increased by more than 10 times compared to the analog method by stopping transmission while the caller is silent.

3) Provide high quality data service.

In digital mode, all signals are processed in digital format, so there is no currency truncation. Therefore, using such a digital system makes it easy to provide data services. In particular, data services, such as fax, have no call disconnection, which is a very good method for data services.

4) The mobile station consumes less power and can be made smaller and lighter.

Since the CDMA network uses the same frequency in adjacent cells or sectors, problems such as frequency relocation do not occur, thereby minimizing mutual interference between adjacent cells. Thus, frequency planning is simple. Analog systems, on the other hand, can't use the same frequency in adjacent cells, which complicates frequency planning. In addition, because it is easy to carry, it is highly utilized compared to a telephone network or Zigbee.

5) It is possible to access the equipment remotely regardless of time, place and distance, and it is easy to install without a separate network configuration.

Therefore, the present invention can secure network quality by applying the CDMA wireless network verified as described above when remote control, as well as stable and efficient system recovery and control.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the emergency recovery system and method for transmitting equipment using a CDMA wireless network according to an embodiment of the present invention.
