电力调度软交换技术组网的研究

Research on Networking Based on Power Dispatching Soft Switch Technology

目前,电力调度通信专网主要基于电路交换技术,通过调度程控交换机及相应的模拟中继线路、数字中继线路,组成多级汇接交换的电话网络。交换机网络业务扩展不再具备优势,以此引入软交换技术,该技术具备更多功能,如视频、图像、多媒体会议等。通过IP中继网关可连接2个网络,同时终端也需要支持接入融合,这样能较好地扩展交换机网络的单一性,加强业务的多样性。目前已经验证方案的有效性,为进一步优化系统打下了坚实基础。

At present, the power dispatching communication private network mainly uses the circuit switching technology that builds multilevel tandem switching telephone network through dispatching SPC exchange and the corresponding simulation trunk circuit and digital trunk lines. Because the expansion of switch network businesses has advantages no longer, this paper introduces the soft switch technology that has much functions including but not limit ： video, image, multimedia conference. Through the IP relay gateway, two networks can be connected and terminals also need support access fusion, which can better remove the singleness of switch network and strengthen the diversity of business. The effectiveness of the solution has been validation, which will lay a good foundation for further system optimization.
