  "abstract": "The present invention relates to repeater supervision system and method for managing and operating remote repeater by supervising and analyzing the quality of wireless and the quality of telephone call on repeater to enlarge a service area. The repeater supervision system comprises a repeater supervision apparatus for collecting electronic waves generated from the repeater, analyzing the collected electronic waves using a program designated beforehand and transmitting the analyzed results, a SMS center for receiving the analyzed results from repeater supervision apparatus and transmitting the analyzed results, a repeater management apparatus for receiving the analyzed results from the SMS center and managing the repeater, a storage for storing the analyzed results by the repeater management apparatus.",
  "claims": [
    "1. A repeater monitoring system for enlarging service areas based on a wireless communications network, comprising: a repeater monitoring apparatus for selecting waves transferred from repeaters, and analyzing the waves by using programs, and transmitting analyzed results; an SMS center for receiving the analyzed results from the repeater monitoring apparatus, and transmitting the analyzed results; a repeater management server for receiving the analyzed results from the SMS center and managing a plurality of repeaters; and a storage apparatus for saving the analyzed results received from the repeater management server, wherein the analyzed result comprises at least one selected from the group consisting of an analysis time, an identification of a terminal manufacturing company corresponding to a mobile communications company (SID), a telephone exchange identification used by the repeater (NID), a noise measurement (PILOT PN), a received message signal strength indicator (RSSI), a signal-to-interference rate(Ec/Io), and a transmitted message signal strength indicator (TX PWR).",
    "2. The system of the claim 1, wherein the analyzed results received from the repeater monitoring apparatus are information of short message type.",
    "3. The system of claim 1, wherein the SMS center further comprises the means for searching and selecting a short message including the analyzed results from the plural short messages.",
    "4. The system of the claim 1, wherein the repeater management server modifies an analysis result transmission period of the repeater monitoring apparatus through the communications network.",
    "5. The system of the claim 4, wherein the communications network is a mobile communications network.",
    "6. The system of the claim 1, wherein the repeater monitoring apparatus comprises an incoming terminal and an incoming line for drawing external power sources, the transformer for adjusting the power sources.",
    "7. The system of the claim 6, wherein the power sources transformed by the transformer is at least one selected from the group consisting of 12V, 7.2V, 3.6V.",
    "8. The system of the claim 1, wherein the repeater monitoring apparatus further comprises the external wave cover case for connecting the repeater with itself."

  "description_excerpt": "The present invention relates to a repeater monitoring system and method for managing and operating a remote repeater by monitoring and analyzing the repeater's quality in wireless and regular telephone calls in order to enlarge a service area.\n\nThe present invention relates to a repeater monitoring system and method for managing and operating a remote repeater by monitoring and analyzing the wireless quality and the telephone call quality of the repeater in order to enlarge a service area.\n\nA base station system and a repeater are used according to traffic density in order to enlarge service areas in a wireless communications network (a mobile communications network, a personal portable communications network etc). At this point, the base station system is installed in the best location according to the number of entrances which can be accommodated by the base station system while it is satisfying the number of entrances in high traffic density service areas and the quality of service required of the wireless communications network.\n\nA repeater is the apparatus used for enlarging the area of service economically in an area having a relatively low density of entrances.\n\nA repeater enlarges a service area by repeating the wireless (RF or IF) signals from a mother base station to the service areas using wireless or broadband transmission apparatuses. A repeater is installed in various areas such as at apartment complexes, on the insides of buildings, and in basements, subways, farms or fishing areas.",
