摘要: 基于号码与交换机分离的思想,采用在现有固定电话网中引入智能用户数据库(SHLR)新网元存储客户信息,交换机或软交换设备通过扩展ISUP、扩展MAP等协议与SHLR进行信息交互等技术,提出了周口市固定电话网智能化方案:采用软交换(SS)/业务交换节点(SSP)+业务数据节点(SDC)外置方案,信令网关(SG)与SS/SSP合设,SS完全访问SDC.该方案有利于支持灵活的资费政策,盘活全网的号码资源,并为下-代网络融合打下基础.Abstract: Based on the idea of the separation of the phone number and the switch,the intelligent user database new severer is introduced into the existing fixed telephone network to save the information of the customer,and by the extended ISUP protocol and the extended MAP protocol,the information exchange is implemented between the switch or the soft switch device and SHLP.The fixed telephone network intelligence method was proposed for Zhoukou city.In this method,SS/SSP and SDC are used,SG and SS/SSP are put together,and SS can access SDC.This is helpful to support flexible tariff policy and activate the telephone number resources to the whole network,and lay the foundation for next-generation network convergence.
