摘　　要：高速SS7信令是一种在数字通信网中使用的公共信道信令技术,适用于无线和有线的公共交换电话网。现有高速信令解析方案可拓展性相对不足,在实际应用场景中扩展成本巨大,并且大都采用外国平台实现。随着国家信息系统软硬件平台对自主可控要求越来越高,文中提出一种基于国产高云FPGA的高速SS7信令解析方案。信令解析过程包括信令采集模块和信令过滤模块,分别对其进行了详细的介绍,并且解析信令的同时统计系统运行信息。相比现有方案,文中方案采用国产平台实现,满足自主可控要求,并对方案进行了模块化参数化设计,可以很容易地实现不同应用场景的扩展。最终设计实现了8路高速SS7信令的并发处理,经过实网测试验证,达到了预期的目的,并成功投入商用。High-speed SS7(signaling system 7)signaling is a public channel signaling technology used in digital communication networks.It is suitable for both wireless and wired public switched telephone networks.The existing high-speed signaling analysis solutions have relatively limited scalability,so expanding them in practical application scenarios is costly,and most of them are implemented on foreign platforms.With the increasing demands for self-controllable hardware and software platforms in national information systems,a high-speed SS7 signaling analysis solution based on domestic Gowin FPGA is proposed.The process of signaling analysis includes a signaling acquisition module and a signaling filtering module,which are described in detail.The system operation information is collected while analyzing the signaling.In comparison with the existing solutions,the proposed solution is implemented on domestic platforms,and it meets with the self-controllable demands.In addition,the solution is designed with modular and parameterized features,so it can accommodate different application scenarios easily.The final design realizes concurrent processing of 8 high-speed SS7 signaling channels.After testing in a real network,the expected results are achieved and the designed scheme is put into commercial use successfully.
