Description

{Repeater operation status monitoring system}

The present invention relates to a repeater operation status monitoring system, which is connected to an output terminal of a repeater, and receives a master modem signal of a repeater through a combiner and receives an output of the repeater, And more particularly, to a repeater operation state monitoring system having an apparatus.

A repeater in a wireless communication is a device that enables a customer's wireless communication service by economically transmitting a base station signal to a remote location in order to effectively resolve a shadow area and to expand a cell coverage.

In other words, a repeater is installed in a building which is not covered by a base station, a shade area such as a basement and a house, and relaying a wireless communication signal from a neighboring base station plays an important role in effectively providing a high quality wireless communication service satisfying a customer's demand do.

These types of repeaters include large / medium repeaters or optical repeaters, which are widely used in areas where the wireless communication signals are relayed or where the customer has a large volume of calls. In addition, there are various types of repeaters such as general households, offices, buildings, elevators, emergency stairs, There is a miniature repeater installed in a small space. Herein, the micro-type repeater is also referred to as a home-type repeater or an indoor-type repeater, and will be collectively referred to as a home-type repeater for convenience of explanation.

Instead of being easy to install because of its small size and low cost, the domestic repeater is optimized to be used for the shading area of small space because the gain is relatively small and the output power is low. Therefore, telecommunication companies that provide wireless communication services are operating massive domestic repeaters to solve many small shadow areas.

On the other hand, in the case of medium / large-sized repeaters, monitoring and management are performed at a remote location using a wireless modem. However, in the case of a home-type repeater, a wireless modem is not used considering economical efficiency of small- Operation monitoring and management are not being performed. In other words, passive operation monitoring is performed in order to confirm the operation state through a business trip or an outbound call when receiving a communication quality complaint of a customer installing a fixed period or home type repeater.

Therefore, there is a problem that it can not actively cope with a failure of a domestic type repeater, causing a customer complaint. In addition, since the domestic type repeater is installed at the customer's premises, there is a problem that if an unspecified customer moves the installation place or moves and removes it arbitrarily, it causes asset loss due to the loss of the domestic type repeater.
