본 발명은 이동통신 시스템의 급전선 공유장치에 관한 것으로, 특히 서로 다른 기지국을 공유함과 아울러 소형이면서 소규모 영역에 적합한 이동통신 시스템의 급전선 공유장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a feeder sharing device of a mobile communication system, and more particularly, to a feeder sharing device of a mobile communication system suitable for small-sized and small-

이동통신 시스템에서 동일한 셀 영역 내에서 각 사업자들이 옥외에 여러개의 안테나들을 설치하고, 기지국과 이들 안테나를 연결하기 위한 급전선들을 설치하게 되므로, 망운용 관리가 매우 복잡한 형태로 구성되어 있으며, 각 사업자들은 안테나와 급전선들이 중복 투자되어 설치비용이 높을 뿐만 아니라, 유지보수도 매우 번거로운 상황이다.In the mobile communication system, each provider installs several antennas in the same cell area, installs feeder lines for connecting the base station and the antennas, and therefore, the network operation management is configured in a very complicated form. In addition to high installation cost due to the overlapping investment of antennas and feeder lines, maintenance is very troublesome.

또한 안테나 설치 위치에 따라 무선 통신 거리가 달라지므로 각 이동통신 회사들마다 안테나 설치 위치에 따른 분쟁이 발생될 수 있으며, 또한 외부에 안테나를 설치하게 되므로 미관상 좋지 않은 문제점이 있었다. Also, since the wireless communication distance varies according to the installation position of the antenna, disputes may occur depending on the installation location of the antenna for each mobile communication company, and the antenna is installed outside.

특히 지하철과 같이 각 이동통신회사들이 밀집하여 기지국 송수신기를 설치하는 경우에는 더욱 심각해진다.Especially, when the mobile communication companies such as the subway are crowded and the base station transceiver is installed, it becomes more serious.

이러한 문제점을 해결하기 위하여, 공개특허 제10-2003-0004533호(이하, '종래기술'이라함)에서는 기지국시스템들의 급전선 공유장치 및 방법을 제안하였다.In order to solve such a problem, Japanese Unexamined Patent Application Publication No. 10-2003-0004533 (hereinafter referred to as "prior art") proposes an apparatus and method for sharing a feeder line of base station systems.

종래기술은, 동일한 셀 영역 내에서 적어도 2개의 다른 회사 기지국장치들의 급전선을 공유하여 단일 안테나에 연결되며, 상기 급전선 공유장치는, 상기 기지국들과 급전선을 통해 각각 연결되며, 상기 대응되는 기지국들과 신호의 송수신경로를 형성하는 양방향 필터로 된 송수신분리들과, 상기 송수신분리기들에서 출력되는 송신되는 신호들을 결합하는 결합기와, 상기 기지국장치들의 각각에 대응되는 수신대역신호를 여파하는 여파기를 구비하며, 상기 여파기들이 상기 안테나로부터 수신되는 신호에서 각각 대응되는 수신대역의 신호를 여파하여 대응되는 상기 송수신분리기들에 분배하는 수신여파기와, 단일의 급전선을 통해 상기 안테나와 연결되며, 상기 결합기에서 출력되는 송신신호를 상기 안테나로 송신하고 상기 안테나로부터 수신되는 신호를 상기 수신여파기에 인가하여 송수신신호를 분리하는 양방향 여파기로 구성된 구조를 갖는다.The prior art is connected to a single antenna by sharing a feeder line of at least two other company base station devices in the same cell area, and the feeder sharing device is connected to the base stations via a feeder line, A combiner for combining signals transmitted from the transmitting and receiving separators, and a filter for filtering a receiving band signal corresponding to each of the base station apparatuses, A demultiplexer for demultiplexing the signals output from the demultiplexers, a demultiplexer for demultiplexing the demultiplexed signals, and a demultiplexer for demultiplexing the demultiplexed signals, Transmitting a transmission signal to the antenna and receiving And a bidirectional filter for applying a signal to the reception filter to separate transmission and reception signals.

그런데 이러한 종래의 급전선 공유기는 필터 형태로 구성되어 있으므로, 높은 가격과 큰 크기로 인하여 소형이면서 소규모 영역에 적용하기에는 무리가 따른다.
However, since the conventional feeder router is composed of a filter type, it is difficult to apply to a small-sized and small-sized area due to its high price and large size.

본 발명은 종래 기술의 문제점을 해결하고자 하여, 선로 분기 형태를 갖는 3개의 하이브리드 커플러를 구비하여 송수신 신호를 분기함으로써 소형이면서 소규모 영역에 적용이 가능한 이동통신 시스템의 급전선 공유장치를 제공하는데 그 목적이 있다.

이와같이 구성된 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention thus constructed will be described in detail with reference to the accompanying drawings.

본 발명의 급전선 공유기(100)는 3×3 하이브리드 형태로서, 이중 3개의 급전선 결합부(110,120,130)와 2개의 안테나 결합부(Ant1, Ant2)를 사용함으로써 3×2 하이브리드 형태를 가지게 된다.The feeder sharer 100 of the present invention is a 3 × 3 hybrid type and has a 3 × 2 hybrid form by using three feeder line couplers 110, 120 and 130 and two antenna couplers Ant1 and Ant2.

급전선 공유기(100)의 내부에는 제1커플러(140), 제2커플러(150), 제3커플러(160), 저항(170), 지연부(180)가 구비되는데, 상기 제1커플러(140)는 제1분기부(141)와 제2분기부(142)를 가지게 된다.A first coupler 140, a second coupler 150, a third coupler 160, a resistor 170 and a delay unit 180 are provided in the feeder sharer 100. The first coupler 140, Has a first branching section (141) and a second branching section (142).

제1급전선 결합부(110), 제2급전선 결합부(120), 제3급전선 결합부(130)를 통해 3개의 이동통신사의 신호가 안테나(Ant1, Ant2)로 전송되는 동작을 설명한다.An operation of transmitting the signals of the three mobile communication companies to the antennas Ant1 and Ant2 through the first feeder line coupler 110, the second feeder line coupler 120 and the third feeder line coupler 130 will be described.

제1분기부(141)는 A사 이동통신 급전선 결합부(110)와 연결되어 1/2의 신호비율로 분기하고, 그 분기된 선로에는 각각 제1안테나 결합부(Ant1)와 제2분기부(142)가 연결된다.The first branching unit 141 is connected to the A mobile communication feeder line coupling unit 110 and branches at a signal ratio of 1/2. The branched lines are respectively connected to the first antenna coupling unit Ant1, (Not shown).

따라서, 급전선 결합부(110)의 신호는 제1안테나 결합부(Ant1)로 1/3의 신호비율로 분기되고, 제2분기부(142)로는 2/3의 신호 비율로 분기된다.Accordingly, the signal of the feeder line coupling unit 110 is branched at the signal ratio of 1/3 to the first antenna coupling unit Ant1, and the signal is branched at the signal ratio of 2/3 to the second branch unit 142.

제2분기부(142)는 제1분기부(141)로부터 분기된 2/3의 신호를 분기 선로를 통해 제3커플러(160)의 제5분기부(161)로 연결하고, 또 다른 분기 선로는 제2커플러(150)와 연결된다.The second branching section 142 connects the 2/3 signal branched from the first branching section 141 to the fifth branching section 161 of the third coupler 160 through the branching line, Is connected to the second coupler (150).

제3커플러(160)는 입력되는 신호를 1/2 신호비율로 다시 분기하는 선로 구조를 가지게 되는데, 제5분기부(161)는 제2분기부(142)의 2/3의 신호비율을 각각 1/3의 신호비율로 분기하게 되어 상기 제5분기부(161)의 하나의 분기선로와 연결되는 제6분기부(162)를 통해 1/3의 신호가 제2안테나 결합부(Ant2)로 전송됨과 아울러 나머지 1/3의 신호는 또 하나의 분기선로로 전송된다.The third coupler 160 has a line structure in which the input signal is branched again at a 1/2 signal ratio. The fifth branching unit 161 divides the signal ratio of 2/3 of the second branching unit 142 by A 1/3 signal is transmitted to the second antenna coupling part Ant2 through the sixth branch part 162 connected to one branch line of the fifth branch part 161 And the remaining 1/3 signal is transmitted to another branch line.

이때, 제6분기부(162)와 연결되지 않는 분기 선로의 종단에는 저항(170)이 구비되어 있으므로, 1/3의 신호는 임피던스 종단된다.At this time, since the resistor 170 is provided at the end of the branch line that is not connected to the sixth branch 162, the signal of 1/3 is terminated in impedance.

따라서, 제1안테나 결합부(Ant1)와 제2안테나 결합부(Ant2)에는 1/3만큼씩의 A사 전송신호가 분기되어 연결되는 것이다.Therefore, the A-phase transmission signals are branched and connected to the first antenna coupling portion Ant1 and the second antenna coupling portion Ant2 by 1/3, respectively.

제2커플러(150)는 입력되는 신호를 1/2의 신호비율로 분기하는 선로 구조를 가지게 되며, 제3분기부(151)와 제4분기부(152)가 구비되는데, 제3분기부(151)는 B사의 급전선 결합부(120)에 연결되고, 제4분기부(152)는 C사의 급전선 결합부(130)에 연결된다.The second coupler 150 has a line structure for branching an input signal at a signal ratio of 1/2, and has a third branching unit 151 and a fourth branching unit 152. The third branching unit 151 151 are connected to the feed line coupling portion 120 of the B company and the fourth branch portion 152 is connected to the feed line coupling portion 130 of the C company.

제3분기부(151)는 급전선 결합부(120)를 통해 전송되는 신호를 1/2씩 분기하여 하나의 1/2 분기된 신호는 선로를 통해 제2분기부(142)로 연결하고, 또 하나의 1/2 분기된 신호는 제4분기부(152)를 통해 제6분기부(162)로 연결한다.The third branching unit 151 branches the signal transmitted through the feed line coupling unit 120 by a half, connects one half branched signal through the line to the second branching unit 142, One half-branched signal is coupled to the sixth branch 162 via the fourth branch 152. [

그러므로, B사의 신호는 제3분기부(151)에서 1/2 신호비율로 분기되고, 제2분기부(142)에서 다시 2/3의 신호비율로 분기되어 제1분기부(141)를 통해 제1안테나 결합부(Ant1)로 전송됨으로써 1/3의 B사 신호가 전송된다.Therefore, the signal of the B company is branched at the half rate of the signal at the third branching section 151, again at the signal rate of 2/3 at the second branching section 142, And transmitted to the first antenna coupling unit Ant1, thereby transmitting the 1/3 B-signal.

또한, 제2분기부(142)를 통해 분기된 B사의 신호는 1/6의 신호가 제5분기부(161)로 공급되고, 제5분기부(161)를 통해 다시 1/12의 신호로 분기된 B사 신호는 제6분기부(162)로 분기되어 공급되며, 이때, 제4분기부(152)와 제6분기부(162)를 통해 분기된 1/4의 B사 신호와 합쳐져서 제2안테나 결합부(Ant2)를 통해 1/3의 B사 신호가 전송된다.Further, a signal of the B company branched through the second branching section 142 is supplied to the fifth branching section 161 with a signal of 1/6, and the 1/16 signal is again supplied through the fifth branching section 161 The signal of the branched B signal is branched and supplied to the sixth branching part 162. At this time, the signal is combined with the 1/4 B signal branched through the fourth branching part 152 and the sixth branching part 162, And the 1/3 B-signal is transmitted through the 2-antenna coupling section Ant2.

즉, 제1안테나 결합부(Ant1)와 제2안테나 결합부(Ant2)를 통해 공히 1/3씩의 B사 신호가 전송되는 것이다.That is, one third of the B signals are transmitted through the first antenna coupling part Ant1 and the second antenna coupling part Ant2.

이때, 제4분기부(152)와 제6분기부(162) 사이에는 지연부(180)가 구비되어 제1커플러(140)의 제2분기부(142)를 경유한 신호와 곧바로 제3커플러(160)의 제6분기부(162)로 향하는 신호와의 위상차를 제거함으로써 제6커플러(162)에서 B사의 신호가 합쳐질 수 있도록 한다.A delay unit 180 is provided between the fourth branching unit 152 and the sixth branching unit 162 so that a signal passing through the second branching unit 142 of the first coupler 140 and a signal passing through the third coupler 142, And the signal directed to the sixth branching part 162 of the second coupler 160 is removed so that the signal of the B company can be combined at the sixth coupler 162.

제3급전선 결합부(130)를 통해 전송되는 C사 신호도 B사 신호와 마찬가지로 제2커플러(150), 제1커플러(140), 제3커플러(160)를 통해 분기되고, 제6분기부(162)를 통해 신호가 합쳐짐으로써 제2안테나 결합부(Ant2)에 1/3의 C사의 신호가 전송되고, 또한 제1안테나 결합부(Ant1)에도 1/3의 C사의 신호가 전송되는 것이다.The C signal transmitted through the third feeder line coupler 130 is also branched through the second coupler 150, the first coupler 140 and the third coupler 160 like the B signal, A signal of 1/3 of the C-company is transmitted to the second antenna coupling unit Ant2 by combining the signals through the first antenna coupling unit 162 and a 1/3 C-signal is transmitted to the first antenna coupling unit Ant1 will be.

결국, 제1안테나 결합부(Ant1)와 제2안테나 결합부(Ant2)를 통해 1/3만큼씩의 A사, B사, C사의 신호가 전송되어지는 것이다.
As a result, signals of the A company, the B company, and the C company are transmitted by 1/3 through the first antenna coupling unit Ant1 and the second antenna coupling unit Ant2.

안테나(Ant1, Ant2)를 통해 신호가 수신되어 제1급전선 결합부(110), 제2급전선 결합부(120), 제3급전선 결합부(130)로 연결되는 과정은 상기에서 설명한 송신 동작의 역동작이므로 상세한 설명은 하지 않는다.
The process of receiving signals through the antennas Ant1 and Ant2 and connecting them to the first feeder line coupler 110, the second feeder line coupler 120 and the third feeder line coupler 130 is the same as the above- Since it is an operation, detailed explanation is not made.
