Over Unicom's backbone network, original SDH loop network architecture already fails to meet present capacity requirement, which must be transformed into ASON, especially for the central-east regions.
在联通的干线网上，原有的SDH环网结构已经不能满足当前的容量要求，必须改造成ason网络，特别是中东部地区。
In this architecture only the control signaling is transmitted to the mobile core network, while user data is directly transmitted to the IP backbone.
这一方案中，只有控制信息被传输到移动核心网，而用户数据直接通过IP骨干网传输，这样可以极大地缓解无线数据业务对移动核心网的负荷。
