Abstract: front page image
(EN)Disclosed are a method and an apparatus for monitoring a radio signal in a cloud-based mobile radio access network. Provided are the method and the apparatus for monitoring a radio signal in a cloud-based mobile radio access network, wherein a separate base station (relay station) includes a base-band unit (BBU) and a remote radio unit (RRU) in a cloud-based radio network, and a digital optical signal is directly branched in an open radio interface between the BBU and the RRU so as to use the same to monitor the radio signal or to analyze performance.
(FR)L'invention concerne un procédé et un appareil pour surveiller un radiosignal dans un réseau d'accès radio mobile basé sur un nuage. L'invention concerne un procédé et un appareil pour surveiller un radiosignal dans un réseau d'accès radio mobile basé sur un nuage dans lequel une station de base séparée (station relais) comprend une unité de bande de base (BBU) et une unité radio distante (RRU) dans un réseau radio basé sur un nuage, et un signal optique numérique est directement ramifié dans une interface radio ouverte entre la BBU et la RRU de façon à utiliser cette dernière pour surveiller le signal radio ou analyser la performance.
(KO)클라우드 이동무선 액세스 네트워크에서의 무선신호 감시 방법 및 장치를 개시한다. 클라우드 기반의 무선 네트워크에서 기저 대역 유닛(BBU: Base-band Unit)과 원격 무선 유닛(RRU: Remote Radio Unit)으로 분리형 기지국(중계국)이 구성되고, 기저 대역 유닛(BBU)과 원격 무선 유닛(RRU) 간에 개방형 무선 인터페이스에서 디지털 광 신호를 직접 분기하여 무선신호 감시 또는 성능 분석에 이용하고자 하는 클라우드 이동무선 액세스 네트워크에서의 무선신호 감시 방법 및 장치를 제공한다.
