무선가입망 기지국 제어기의 VCIA장치VCIA device of base station controller

본 발명은 WLL(Wireless Local Loop)시스템에 관한 것으로, 특히 기지국 제어국인 RPC(Radio Port Controller)에 속하는 TCU(Transcoder Unit)블럭에 위치하는 VCIA(Vocoder Switch Unit)보드에 있어서, 타임 스위치인 TSU(Time Switch Unit)에서 채널화된 E1프레임 신호를 수신하여 각각의 슬롯을 VSOA(Vocoder Selector Operation)보드로 분배할 수 있도록 한 무선가입망 기지국 제어기의 VCIA장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless local loop (WLL) system, and more particularly to a VCIA (Vocoder Switch Unit) board located in a Transcoder Unit (TCU) block belonging to a Radio Port Controller (RPC), which is a base station control station. The present invention relates to a VCIA device of a base station controller for a wireless access network that receives a channelized E1 frame signal from a time switch unit and distributes each slot to a VSOA board.

일반적으로 WLL은 가입자 선로(Local)의 무선화를 의미하는 것으로 가입자의 댁내를 연결하는 유선대신 무선장치를 이용하여 무선으로 가입자 선로를 구성하는 것을 말한다.In general, the WLL refers to the wirelessization of the subscriber line (Local), and refers to the wireless configuration of the subscriber line by using a wireless device instead of a wire that connects the subscriber's home.

WLL은 전화, 음성데이타, 패킷(Packet)데이타, ISDN서비스를 고정된 RF채널을 통해서 기존 동선이나 광 통신보다 저렴하고 만족시키는등의 뛰어난 기능을 보유하고 있기 때문이다.This is because WLL has excellent functions such as making telephone, voice data, packet data, and ISDN service cheaper and satisfying than existing copper wire or optical communication through fixed RF channel.

종래의 셀룰라 통신에 비해 고정 통신의 특징인 서비스가 가능하고 핸드오프나 전력제어등의 기능을 필요로하지 않기 때문에 훨씬 통신과정이 간단하여 경제성이 뛰어난 장점을 가지고 있다.Compared to the conventional cellular communication, it is possible to provide a service which is a characteristic of fixed communication and does not require a function such as handoff or power control.

또한, 기존의 유선을 설치하기 어려운 곳과 농어촌과 같이 인구밀도가 희미한 지역이나 국가별로는 초기 시설확보를 위해 동선이나 광케이블보다 투자가 적게든다는 점에서 개발 도상국등지에서 많이 사용되고 있는 실정이다.In addition, in areas and countries where population density is sparse, such as rural areas where it is difficult to install existing wires, investment in developing countries is much lower in terms of lower investment than copper wire or optical cable to secure initial facilities.

통상, WLL시스템은 기지국(RP), 기지국 제어기(RPC), 가입자 접속장치(RIU)로 구성되며, 기지국 제어기(RPC)는 교환국과 기지국(RP)사이에 위치하여 교환국과 기지국(RP)을 연결시켜주며 호처리 기능, 가입자 트래픽(Traffic)처리 기능, 전력제어 기능, 트래픽 접선기능, 운용 관리기능, 전용회선 종단장치와의 인터페이스 기능, 신호전송 및 기지국(RP)관리기능을 수행한다.In general, the WLL system includes a base station (RP), a base station controller (RPC), and a subscriber access unit (RIU), and the base station controller (RPC) is located between the switching center and the base station (RP) to connect the switching center and the base station (RP). It performs call processing function, subscriber traffic processing function, power control function, traffic tangential function, operation management function, interface function with dedicated line termination device, signal transmission and base station (RP) management function.

이를 위하여 기지국 제어기(RPC)는 기지국과 E1 및 HDSL로 접속되며, WLL교환기로는 E1/V5.2로 중계처리한다.For this purpose, the base station controller (RPC) is connected to the base station by E1 and HDSL, and relayed by E1 / V5.2 by the WLL exchanger.

기지국 제어기 블럭은 신호 멧세지의 전달기능과 호처리기능, 트랜스코딩, 스위치 기능을 수행하기 위하여 크게 4개의 블록으로 구성되어 있다.The base station controller block is largely composed of four blocks to perform signal message transfer, call processing, transcoding, and switch functions.

먼저, CDMA접속 서브 시스템은 기지국과 기지국 제어기간 E1/HDSL중계선 정합기능을 수행하며, 트랜스코딩 유니트는 64Kbps의 PCM음성 부호화 신호로의 변환기능을 수행하는 트랜스코더를 수행한다.First, the CDMA access subsystem performs a base station and base station control period E1 / HDSL relay line matching function, and the transcoding unit performs a transcoder for converting a 64 Kbps PCM speech coded signal.

또한, 반향제어기능이 기지국 제어기에 구현되며 MUX/DMUX의 ADPCM, PCM의 기능을 수행한다.In addition, the echo control function is implemented in the base station controller and performs the functions of ADPCM and PCM of MUX / DMUX.

그리고 망접속 스위치는 기지국 및 WLL교환기와의 트래픽 및 제어정보, 데이타 서비스를 스위칭한다.The network access switch switches traffic, control information, and data services between the base station and the WLL exchange.

한편, 기지국의 착발신 호터리 지원, 메시지 처리등 각종 호처리 기능과 기지국 제어기내의 서브시스템 상태관리 및 WLL교환기와 가입자 접속장치사이의 제어신호 포맷등의 기능을 수행하는 프로세서이다.On the other hand, it is a processor that performs various call processing functions such as incoming / outgoing call support and message processing of the base station, subsystem status management in the base station controller, and control signal format between the WLL switch and the subscriber access device.

본 발명은 타임 스위치인 TSU에서 채널화된 E1프레임 신호를 수신하여 각각의 슬롯을 VSOA보드로 분배할 수 있도록 한 무선가입망 기지국 제어기의 VCIA장치를 제공하는데 그 목적이 있다.An object of the present invention is to provide a VCIA apparatus of a base station controller for a wireless access network that receives a channelized E1 frame signal in a time switch TSU and distributes each slot to a VSOA board.
