Signal time slot crossing method, device and system based on packet switching

The embodiment of the invention provides a signal time slot crossing method, device and system based on packet switching, and the method comprises the steps: carrying out the frame alignment processing and pointer copying processing of an original synchronous digital hierarchy frame signal, and obtaining a target synchronous digital hierarchy frame signal; analyzing the target synchronous digital hierarchy frame signal, and generating a time slot data packet; according to the set packet switching corresponding table, performing packet switching on the time slot data packet; and the time slot data packet after packet exchange is reloaded to generate an updated synchronous digital hierarchy frame signal after time slot crossing, so that the requirement of time slot crossing of a super-large-scale SDH signal can be met, and the output efficiency of the SDH signal is improved. 本发明实施例提供了一种基于包交换的信号时隙交叉方法、装置和系统，所述方法包括：对原始同步数字体系帧信号进行帧对齐处理和指针复制处理，得到目标同步数字体系帧信号；对目标同步数字体系帧信号进行解析，并生成时隙数据包；根据设置的包交换对应表，对时隙数据包进行包交换；对包交换后的时隙
