| description | To allow a base station side to quickly recognize communication failure due to breakage of a leaky coaxial cable in a wireless communication system in which the leaky coaxial cable is used for communication between a plurality of a base stations and mobile stations.SOLUTION: Control units 11A and 11B cause transmission units 12A and 12B to generate and transmit an A-series signal and a B-series signal based on transmission data, respectively. The A-series signal passes through an LCX50A and an LCX50B as indicated by a dashed arrow A. The B-series signal passes through the LCX50B and the LCX50A as indicated by a dashed arrow B. The B-series signal passes through the LCX50A and then flows to a base station 10A side, and the control unit 11A recognizes that the B-series signal has flowed via the LCX50B and 50A. When the LCX50A is disconnected, the base station 10A side cannot receive the B-series signal. In this case, the base station 10A side can estimate that the LCX50A or LCX50B is disconnected.SELECTED DRAWING: Figure 2
【課題】複数の基地局と移動局との間の通信のために漏洩同軸ケーブルが用いられた無線通信システムにおいて、漏洩同軸ケーブルの破損による通信の障害を基地局側から迅速に認識する。【解決手段】制御部１１Ａ、１１Ｂはそれぞれ送信データに基づいてＡ系列信号、Ｂ系列信号を送信部１２Ａ、１２Ｂに生成・送信させる。Ａ系列信号は、破線矢印Ａで示されるようにＬＣＸ５０Ａ、ＬＣＸ５０Ｂを通過する。Ｂ系列信号は、点線矢印Ｂで示されるようにＬＣＸ５０Ｂ、ＬＣＸ５０Ａを通過する。Ｂ系列信号はＬＣＸ５０Ａを通過してから基地局１０Ａ側に流れ、制御部１１ＡはＢ系列信号がＬＣＸ５０Ｂ、５０Ａを介して流れたことを認識する。ＬＣＸ５０Ａが切断された場合、基地局１０Ａ側でＢ系列信号を受信することができない。この場合には、基地局１０Ａ側では、ＬＣＸ５０Ａ又はＬＣＸ５０Ｂが切断したと推定することができる。【選択図】図２ |
