5 and 6 are views showing the operation of the repeater remote control / management system according to the first and second embodiments of the present invention.

The present invention relates to a repeater, its operation method and a repeater remote control / management system and method.

In wireless networks (mobile networks, personal mobile networks), base stations and repeaters are used depending on the traffic density to expand the coverage area. The base station is optimally installed according to the number of subscribers distributed in the service area in the high traffic density area and the number of subscribers that the base station can accommodate while satisfying the quality of service required by the wireless communication network.

Such a repeater needs continuous management and maintenance to continuously provide optimum call quality to subscribers in a wireless communication network.

Initially, field operators performed condition monitoring and control management of repeaters by site visits. However, as the number of repeaters increases, manpower and time are consumed enormously. In order to solve this problem, a repeater monitoring system that monitors the repeater for abnormalities has been introduced.

1 is a view showing a conventional repeater monitoring system.

As shown in FIG. 1, the repeater monitoring system includes a repeater 20, a base station 30, a short message center (SMC) 40, and an NMC 50.

A repeater monitoring device (not shown) is installed inside the repeater 20, and a repeater monitoring server (not shown) is installed inside the NMC (Network Management Center) 50.

The repeater monitoring apparatus measures and reports the radio signal of the repeater 20 to the NMC 50 when there is a repeater operation status request from the repeater monitoring server. In addition, the repeater monitoring device reports the current state to the NMC 50 when the repeater 20 fails or the wireless RF environment worsens.

In order to report the state of the repeater 20 to the NMC 50, the repeater monitoring apparatus uses the short message service (SMS) through the wireless terminal 10 in the repeater 20 to send a short message to the state information of the repeater 10. It is generated and transmitted to the SMC 40 through the base station 30, this short message is stored in the SMC and transmitted to the relay monitoring server.

Repeater monitoring server receives a short message to determine whether there is a problem with the repeater. At this time, when a failure is detected from the repeater, the NMC 50 displays the failure on the GIS screen or the PC client screen, and the operator of the NMC 50 that recognizes the failure therefrom informs the field operator 1 of the failure and dispatches it on site. Command

As such, when the conventional repeater monitoring system recognizes a failure of a repeater such as a decrease in output of the repeater in a remote main system, it is necessary to take measures for the failure of the repeater through direct on-site dispatch. This is a problem that takes a lot.
