技術說明

本發明揭露一種使用者裝置訊號合成系統與分析訓練方法，可於電信系統之環境中於不存在實體元件之地理位置產生虛擬終端裝置訊號並與電信系統溝通，包含：終端裝置實體收發裝置、虛擬終端裝置排程模組、控制單元、地理資訊截取裝置、實體層通道建模器以及實體層通道分析訓練方法模組、待測電信系統。數個終端裝置實體收發裝置與待測電信系統之通道資訊，並與接收到地理資訊截取裝置之實體層通道建模器建模之結果，提供給實體層通道訓練模組 。並根據實體層通道訓練模組訓練之結果推算指定地理位置之通道特徵參數，此參數傳遞至虛擬終端裝置排程模組後，由虛擬終端裝置排程模組週期性地進行時域及頻域之訊號排程策略，將排程策略至數個終端裝置實體收發裝置進行訊號發送，其數個仿真天線單元發送訊號之結果，將使電信系統將數個終端裝置實體收發裝置發送之訊號辨識為指定地理位置之使用者裝置所發送之訊號，並由控制單元進行電信訊號內容之設計，流程及參數之指定及控制層、資料層行為之管控。藉此使用者裝置訊號合成系統及分析訓練方法，可在不改變使用者裝置訊號合成系統之硬體位置情況下，靈活地模擬指定範圍內任一地理位置之使用者裝置訊號及行為，並使用固定數量之終端裝置實體收發裝置模擬不固定數量之使用者裝置行為，可大幅降低測試所需之設備及人力。 A signal synthesizing system for user equipment and an analytical training method is revealed in this invention. The proposed system and method enable communications between telecommunication systems and virtual user devices which are generated for channel behaviors in specific locations. The invention includes physical transceivers of end devices, scheduling modules of virtual end equipment, control unit, geo-information sensing device, physical channel modeler and analytical training module for physical channel, and an under-test telecommunication system. The channel information between multiple physical transceivers of end devices and under-test telecommunication system, and modeling results of physical channel from channel modeler according to geo-information sensing device are provided to physical channel training module. According to the obtained channel feature parameters of specific locations from physical channel training module, after the parameters are delivered to scheduling modules of virtual end equipment, the scheduling modules of virtual end equipment periodically conduct time-frequency resource allocation strategies. The strategies are delivered to multiple physical end devices to transmit. The effective signals transmitted from the virtual antenna units result in that the signals sent from transceivers of physical end are taken as those sent from virtual devices at specific locations by the telecommunication system. Control units are in charge of designing contents of telecommunication signals, procedures and assignment of parameters and management of physical and data layers.
