무선가입자망의 이원 정합장치의 에러 발생시 채널재설정장치Channel reset device in case of error of binary matching device in wireless subscriber network

본 발명은 WLL(Wireless Local Loop)시스템에 관한 것으로, 특히 E1정합장치의 페일 또는 에러 발생시 이를 감지하여 현재 연결설정되어 있지 않은 다른 E1의 채널에 연결을 재설정하여 줌으로써 사용중인 호가 해제되는 것을 방지할 수 있도록 한 WLL의 E1정합장치의 에러 발생시 채널 재설정장치에 관한 것이다.The present invention relates to a WLL (Wireless Local Loop) system. In particular, when a failure or error occurs in an E1 matching device, the present invention detects it and resets the connection to another E1 channel that is not currently connected to prevent the call being released. A channel reset device in case of an error in the E1 matching device of the WLL.

일반적으로 WLL시스템의 RPC(Radio Port Controller:기지국 제어장치)블록에 있어서, 각 유니트(예를들어 TSU(Time Switch Unit),SPU(Signal Processing Unit))를 연결하는 물리적 전송방식으로 E1프레임 방식의 정합장치를 사용하는데 호 설정과정을 통해 연결설정된 정보들이 E1정합장치를 통해 전송될 때 E1정합장치에 페일(Fail) 또는 에러(Error)가 발생하면 사용중인 호(Call)의 연결해제의 원인이 된다.In general, RPC (Radio Port Controller) block of WLL system is a physical transmission method that connects each unit (for example, TSU (Time Switch Unit), SPU (Signal Processing Unit)). If a failure or error occurs in the E1 matching device when the information set up through the call setup process is transmitted through the E1 matching device, the cause of disconnection of the call is in use. do.

종래에는 CCU(Call Control Unit)에서 제어부로 채널 할당 명령을 내리면 제어부는 채널할당부에 정보를 주어 채널할당부로 하여금 채널을 할당하도록 하였다.Conventionally, when a channel allocation command is given to a control unit from a call control unit (CCU), the control unit gives information to the channel allocation unit so that the channel allocation unit allocates a channel.

그러나 이와같은 종래의 채널할당수단에 있어서는, 채널할당후 정보전송시 에러가 발생하면 음성신호가 끊어져 사용자는 호가 끊어진 것을 단지 통화단절로 인식하게 되어 WLL망의 신뢰성을 저하시키는 문제가 있었다.However, in the conventional channel assignment means, if an error occurs in the transmission of information after channel assignment, the voice signal is disconnected and the user recognizes that the call is only disconnected, thereby reducing the reliability of the WLL network.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 본 발명의 목적은 E1정합장치의 에러발생시 연결되어 있지 않은 다른 채널에 자동적으로 연결시켜 줄 수 있도록 하는 WLL의 E1정합장치의 에러 발생시 채널 재설정장치를 제공하는데 있다.The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a WLL E1 matching device that automatically connects to another channel that is not connected when an error occurs in the E1 matching device. It is to provide a channel reset device.

이와같이 구성된 본 발명을 도 3의 동작흐름도를 참고로 하여 설명하면 다음과 같다.Referring to the present invention configured as described above with reference to the flow chart of FIG.

먼저,채널상태 감시부(10)에서 E1의 상태를 순서대로 감시하여 정상인가를 판단한다.(S1).First, the channel state monitoring unit 10 monitors the state of E1 in order to determine whether it is normal (S1).

만일 정상상태가 아니면,채널상태 감시부(10)에서 페일 또는 에러상태인 E1의 정보를 제어부(20)로 알린다(S2,S3).If it is not in the normal state, the channel state monitoring unit 10 informs the control unit 20 of the information of the failing or error state E1 (S2, S3).

따라서,제어부(20)에서는 CCU에 E1의 상태가 비정상인 것을 알리고 채널 재설정을 요구한다(S4).Therefore, the controller 20 notifies the CCU that the state of E1 is abnormal and requests a channel reset (S4).

그러면 제어부(20)로부터 채널 재설정 요구를 받은 CCU에서는 재설정할 E1 및 채널을 선정하여 다시 제어부(20)에 알리며(S5), 제어부(20)는 선정된 E1 및 채널을 채널 할당부(30)에 전송한다(S5,S6).Then, the CCU receiving the channel reset request from the controller 20 selects the E1 and the channel to be reset and informs the controller 20 again (S5). The controller 20 transmits the selected E1 and the channel to the channel allocator 30. Transmit (S5, S6).

또한,채널할당부(30)에서는 상기 제어부(20)에서 전송된 E1 및 채널정보를 기반으로 채널을 재설정한다(S7).In addition, the channel allocator 30 resets the channel based on the E1 and the channel information transmitted from the controller 20 (S7).

이어 채널 할당부(30)에 의해 재설정된 채널은 정보전송부(50)를 통하여 전송된다(S8).Subsequently, the channel reset by the channel allocator 30 is transmitted through the information transmitter 50 (S8).

이상에서 설명한 바와같은 본 발명은 E1정합장치의 페일 또는 에러발생시 이를 감지하여 현재 연결되어 있지 않은 다른 E1의 채널에 연결을 재설정함으로써 사용자의 호가 해제되는 것을 방지할 수 있어 WLL망의 신뢰성을 향상시킬 수 있는 효과가 있다.As described above, the present invention can detect the failure or error of the E1 matching device and prevent the user's call from being released by resetting the connection to another E1 channel that is not currently connected, thereby improving the reliability of the WLL network. It can be effective.
