본 발명은 사설 구내 교환기에 구내 무선통신용 착/발신 장치를 설치하고 무선통신 회선을 실장한 구내 무선통신망 구축에 관한 것으로, 더 상세하게는 사설 구내 교환기에서 곧바로 무선통신망에 접속할 수 있는 유/무선 통신 인터페이스 기술을 이용한 구내 무선통신 착/발신 장치를 공급하여 구내 유/무선통합 통신망을 구축함으로써, 가입자에게는 유/무선 통신 이용선택의 폭을 넓혀주고 양질의 통신 서비스와 통신비 부담을 최소화할 수 있도록 한, 구내 무선통신용 착/발신 장치에 관한 것이다.The present invention relates to the construction of an on-premises wireless communication network in which a wireless communication line is installed and installed in a private exchange, and more particularly, a wired / wireless communication which can be directly connected to a wireless communication network at a private exchange. By providing on-premises wireless communication incoming / outgoing devices using interface technology to build a wired / wireless integrated communication network, subscribers can expand their choice of wired / wireless communication and minimize the burden of high-quality communication services and communication costs. In addition, the present invention relates to an on-premises wireless communication device.

일반적으로, 사설 교환기(PABX, 키폰)는 소량의 DID 및 DOD 회신으로 다수 구내 내선 가입자가 아무런 불편없이 통신을 행할 수 있어 국선 증가 예방 및 내선통화만큼의 통신비를 절감하는 등 큰 효과를 거두었으나 무선통신의 발전과 더불어 이동전화 가입자가 급격히 증가하였고, 이로 인해 이동전화, 무선호출 등의 무선통신 통화량의 증가는 곧바로 통신비 증가로 이어져 크나큰 부담이 되고 있다.In general, private exchanges (PABXs, key phones) have a great effect, such as preventing large number of trunk lines and reducing communication costs as much as internal calls, because a large number of extension subscribers can communicate without any inconvenience with a small amount of DID and DOD reply. With the development of telecommunications, the number of mobile phone subscribers has increased drastically. As a result, the increase in the amount of wireless communication calls such as mobile phones and wireless calls has led to an increase in communication costs, which is a huge burden.

종래의 구내 유선통신망 구축 계통도는 도 1 에 도시된 바와 같이, 구내 전화(1)로부터 구내 교환기(2)를 통하여 입력된 신호는 유선통신 교환기(3)를 거쳐 일반 전화(4)로 유선 통신이 이루어졌다.As shown in FIG. 1, the conventional wired network construction schematic diagram shows that a signal inputted from an on-premises telephone 1 through an on-premises exchange 2 is routed to a general telephone 4 via a wired communication switch 3. Was done.

한편, 무선 통신시에는 구내 전화(1)로부터 구내 교환기(2)를 통하여 입력된 신호가 유선통신 교환기(3)를 거쳐 무선 교환기(5)로 출력되어 기지국(6)을 통해 핸드폰 등의 단말기(7)로 무선 통신하게 되었다.On the other hand, during wireless communication, a signal input from the premises telephone 1 through the premises exchange 2 is outputted to the wireless exchanger 5 via the wired communication exchange 3, and through the base station 6, a terminal such as a mobile phone ( 7) to wireless communication.

따라서, 구내 내선 가입자가 이동전화 이용시 구내 통신망에서 유선통신망과 무선통신망이 연결되는 등 복잡한 구조로 구성되어 있다.Therefore, when the extension subscribers use mobile phones, the wired communication network and the wireless communication network are connected in the premises communication network.

즉, 유/무선 통신간에 불필요한 접속이 발생되는 문제점이 있었다.That is, there is a problem that unnecessary connection occurs between wired and wireless communication.

이에 본 발명은 상기한 바와 같은 종래의 문제점을 해소시키기 위하여 창안된 것으로, 사설 구내 교환기에서 곧바로 무선통신망에 접속할 수 있는 유/무선 통신 인터페이스 기술을 이용한 구내 무선통신 착/발신 장치를 공급하여 구내 유/무선통합 통신망을 구축함으로써, 가입자에게는 유/무선 통신 이용선택의 폭을 넓혀주고 양질의 통신 서비스와 통신비 부담을 최소화할 수 있도록 한, 구내 무선통신용 착/발신 장치를 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned problems, and provides a wireless communication in / out device in the premises using wired / wireless communication interface technology that can be directly connected to a wireless communication network in a private branch exchange. The purpose of the present invention is to provide an on-premises wireless communication call / outgoing device to expand subscribers' choice of wired / wireless communication and to minimize the cost of communication service and cost by establishing a wireless / integrated communication network.

A wireless communication base station 60, which is a wireless communication network, is connected.

여기서, 구내 전화(10)에서 구내 무선통신 착/발신 장치(50)를 이용한 무선 통신망 실시예는 다음과 같다.Here, an embodiment of the wireless communication network using the on-premises wireless communication call / exit device 50 in the campus telephone 10 is as follows.

먼저, 구내 교환기(20)에서 무선통신 접속번호인 코드를 부여하면, 키폰을 포함하는 구내 교환기(20)는 구내 무선통신 착/발신 장치(50)의 무선통신망을 통하여 어드레스를 분류하고, 무선 통신 국번을 다이얼링하면 A/D 변환 장치부(52)에 의해 아날로그 신호는 디지털 신호로 변환되고, 디지털 신호로 변환된 발신 신호는 통품 장치부(53)를 통해 통화의 품질이 향상된 후, 착/발신 장치부(54)로부터 발생되는 통화 신호에 의해 무선통신 기지국(60)과 접속되어 다시 이동전화 교환기(70)에 접속한다.First, when the premises exchange 20 assigns a code which is a wireless communication access number, the premises exchange 20 including a key phone classifies an address through a wireless communication network of the premises wireless communication call / exit device 50, and wireless communication. When dialing the station number, the analog signal is converted into a digital signal by the A / D conversion unit 52, and the outgoing signal converted into the digital signal is improved through the communication device unit 53, and then the incoming / outgoing call is made. The call signal generated from the device section 54 is connected to the wireless communication base station 60 and again to the mobile telephone exchange 70.

한편, 동일한 통신사간의 접속은 상기 이동전화 교환기(70)가 자사 기지국(110)을 통해 단말기(120)에 접속되어 통화가 이루어지고, 타 무선 통신사와 접속일 경우는 상기 이동전화 교환기(70)가 타 무선 교환기(80)와 타 기지국(90)을 통해 단말기(100)에 접속되어 통화된다.On the other hand, in the connection between the same communication company, the mobile telephone switchboard 70 is connected to the terminal 120 through its base station 110, and a call is made. When the mobile telephone switchboard 70 is connected to another wireless carrier, The mobile station 80 is connected to the terminal 100 through another base station 90 to communicate.

또한, 상기 이동전화 교환기(70)가 기타 통신기(130)에 접속되어 국제 전화, 무선 호출 등도 이루어진다.In addition, the mobile telephone exchange 70 is connected to the other communication unit 130 to make international calls, radio calls, and the like.

상기 구내 무선통신 착/발신 장치(50)는 일체형 또는 분리형으로 제작할 수 있고, 대용량의 구내 교환기(20) 및 소용량의 키폰에도 적용할 수 있다.The on-premises wireless communication call / outgoing device 50 may be manufactured in an integrated or detachable type, and may be applied to a large-capacity campus exchange 20 and a small-capacity keyphone.

무선통신 회선은 DID 회선과 DOD 회선으로 분류하고, 필요에 따라 회선수 증설 또는 감축을 쉽게할 수 있도록 구내 무선통신 착/발신 장치(50)를 탈/부착할 수 있다.The wireless communication line is classified into a DID line and a DOD line, and if necessary, the wireless communication attaching / outgoing device 50 may be detached / attached so that the number of lines can be easily expanded or reduced.

이 장비의 적용 대상으로는 011, 016, 017, 018, 019, 무선 화상 전화(IMT 2000), 위성폰에 적용할 수 있으며, 또한 구내 무선통신 착/발신 장치(50)의 조정 또는 교체로 무선통신사를 선택할 수 있도록 구성되어 있다.This equipment can be applied to 011, 016, 017, 018, 019, wireless video phone (IMT 2000), satellite phone, and also wireless by adjusting or replacing the wireless communication terminator. It is configured to select a carrier.

이상에서 상세히 설명한 바와 같이 본 발명에 따른 구내 무선통신용 착/발신 장치는, 구내 통신망에서 무선통신 이용시 유선통신 교환기를 통해 무선통신망에 접속되던 것을 아날로그/디지탈 변환 기술을 이용한 무선통신 착/발신 장치를 이용하여 구내 통신망에서 곧바로 무선통신망에 접속할 수 있도록 함으로서, 불필요한 접속 발생을 방지하고 복잡하게 구성되어 있는 유/무선 통신 접속망을 단순화시킬 수 있는 효과가 있다.As described in detail above, the on-premises wireless communication wearable / outgoing device according to the present invention is connected to a wireless communication network using an analog / digital conversion technology that is connected to a wireless communication network through a wired communication switch when using wireless communication in the on-premises communication network. By using it to directly access the wireless communication network in the premises communication network, there is an effect that can prevent unnecessary connection occurrence and simplify the complicated wired / wireless communication connection network.

따라서, 구내 통신망에서 무선통신 접속시 불필요한 접속을 차단하고 곧바로 무선통신망에 접속할 수 있으며, 구내에 무선통신망이 구축되어 소량의 무선통신 회선을 다수의 구내 내선 가입자가 공동으로 사용할 수 있고, 구내 무선통신 착/발신 장치를 장착함으로 인해 통화료를 절감할 수 있는 효과가 있다.Therefore, in the campus communication network, unnecessary connection can be cut off when connecting to the wireless communication network, and the wireless communication network can be immediately connected, and the wireless communication network is established in the premises, so that a small number of wireless communication lines can be jointly used by a plurality of extension subscribers. Equipped with the incoming / outgoing device has the effect of reducing the call charges.
