The terminologies used herein are terms used to properly represent preferred embodiments of the present invention, which may vary depending on the user, the intent of the operator, or the practice of the field to which the present invention belongs. Therefore, the definitions of these terms should be based on the contents throughout this specification.

1 is a diagram illustrating a configuration of a repeater failure prediction system according to an embodiment of the present invention.

As shown in FIG. 1, the present invention can be configured as a repeater failure prediction device 100, which is a repeater management server that manages a plurality of repeaters 200 and a plurality of repeaters 200.

In this case, the repeater 200 includes a level control module to which an automatic level control (ALC) function is added, so that the repeater 200 can automatically control the level of the repeater 200 to operate the repeater 200, And may control the repeater 200 to operate automatically according to the setting of the prediction apparatus 100. [

Meanwhile, the repeater failure prediction device 100 of the present invention can support all of the bidirectional repeaters.

That is, since the repeater 200 performs a function of receiving a signal from the base station and transmitting the received signal back to the subscriber station, the repeater 200 can predict and check deterioration of the function of receiving and transmitting the signal have.

Accordingly, the present invention proposes a method of predicting the bi-directional characteristics of the repeater 200, that is, deterioration with respect to forward and reverse transmission and reception, and designating an inspection target of the repeater 200 accordingly.

The repeater failure prediction apparatus 100 of the present invention serves as a repeater management server capable of collecting and managing operational information from at least one repeater 200. Referring to FIG. 2, The prediction method is described as follows.

2 is a block diagram illustrating a configuration of a repeater failure prediction apparatus according to an embodiment of the present invention.

First, the repeater selector 110 selects at least one repeater 200 for transmitting information to the subscriber terminal.

At this time, the repeater failure prediction apparatus 100 of the present invention can collect operational information on a function of transmitting information to a subscriber terminal, which is a forward direction signal transmission / reception function of the repeater 100, as described above.

That is, the information collecting unit 120 of the repeater failure prediction apparatus 100 collects operating information from the repeater 200.

In this case, the operation information is repeater setting information collected by a power control unit (PCU) included in the repeater, and various information collected by the repeater 200 is transmitted to the repeater failure prediction apparatus 100 And is used as data for analyzing the state of the repeater 200.

Next, the determination unit 130 determines the output gain information of the repeater 200 by analyzing the operation information.

At this time, the output gain information of the repeater 200 includes information such as a gain margin, which is margin gain information for upwardly changing the output of the repeater 200, and ALC Atten, which is margin gain information for correcting the output of the repeater.

Next, the determination unit 140 determines whether or not the output of the repeater 200 can be compensated based on the determination result.

That is, the determination unit 140 can determine that the output of the repeater 200 can not be compensated when the output gain information of the repeater 200 is deteriorated by more than the maximum gain information.

Finally, if the output of the repeater 200 can not be compensated as a result of the determination, the check target selecting unit 150 selects the repeater 200 as a site to be inspected.

For example, when the operator of the repeater failure prediction apparatus 100 has a value of maximum gain information derived through a specific experiment as '6 dB', if the sum of the gain margin and the ALC Atten is less than 7 as shown in Equation 1 below , The inspection object selection unit 150 can select the relay apparatus 200 from which the above-described result is derived as the site to be inspected.

Gain margin + ALC Atten <7

The determination unit 140 determines that the output of the repeater 200 can be compensated when the output gain information of the repeater 200 is included in the range of the maximum gain information, 150 may compensate the output of the repeater 200, the repeater 200 may be selected as the remote control target station.

For example, when the operator of the repeater failure prediction device 100 sets the range of the maximum gain information as 'Algorithm ALC Atten is 3 or less and Gain margin is 10 or more' as an algorithm derived through a specific experiment, When the output gain information includes the maximum gain information range of 'ALC Atten is 3 or less and the gain margin is 10 or more', the check target selecting unit 150 outputs as much output as the operator of the repeater 200 desires It can be identified as a state that can compensate and can be selected as a remote control check target site.

ALC Atten is 3 or less and gain margin is 10 or more

As described above, according to the present invention, the operation information of the repeater is analyzed through a specific algorithm, and the degree of deterioration of the repeater can be grasped and it can be determined whether the repeater is a local inspection target site or a remote control target station according to the deteriorated repeater condition.

The repeater failure prediction method according to one embodiment of the present invention will now be described with reference to FIGS. 3 to 4 as follows.

At this time, since the method is similar to the method performed using the repeater failure prediction device 100, it includes all of the functional elements of the device, and thus a detailed description thereof will be omitted for brevity.

3 is a flowchart illustrating a repeater failure prediction method according to an embodiment of the present invention.

3, the repeater selector 110 selects one or more repeaters 200 for transmitting information to the subscriber station (S310).

Next, the information collecting unit 120 collects operating information from the repeater 200 (S320).

Next, the determination unit 130 determines the output gain information of the repeater 200 by analyzing the operation information (S330).

Next, the determination unit 140 determines whether the output of the repeater 200 can be compensated based on the determination result (S340).

Finally, when it is determined that the output of the repeater 200 can not be compensated as a result of the determination, the check target selection unit 150 selects the repeater as a site to be inspected (S350).

4 is a flowchart illustrating an example of an algorithm for determining a deterioration state of a repeater according to an embodiment of the present invention.

For example, as shown in FIG. 4, when the value of the maximum gain information derived by the operator of the repeater failure prediction device 100 through a specific experiment is '6dB' And the ALC Atten is less than 7 (Gain margin + ALC Atten &lt; 7), the repeater 200 having the above-described result can be selected as a site to be inspected.

If the check target selecting unit 150 can compensate the output of the repeater 200 as a result of the determination, the check target selecting unit 150 may select the repeater 200 as a remote control target station.

For example, as shown in FIG. 4, the check target selecting unit 150 determines the range of the maximum gain information as 'an ALC Atten' of 3 or less by an algorithm derived by an operator of the repeater failure prediction device 100 through a specific experiment If the gain gain is set to 10 or more, if the output gain information is included in the maximum gain information range of 'ALC Atten is 3 or less and the gain margin is 10 or more', the operator of the repeater 200 Can be compensated for and can be selected as the target of remote control check.
