摘　　要：随着移动互联网ctwap业务迅猛发展,原有的一个IP地址空间不能满足激增业务量的需要。针对私网地址紧缺现象,从而提出移动核心网融合承载NAT网元建设方案。该方案中私网地址复用采用融合承载网元旁挂CE,通过承载网CE中转的方式,CE将需要进行私网地址复用的业务转发到融合承载网元进行NAT转换和承载等技术手段,使得综合承载网元成对部署,两台综合承载网元工作在主备状态时,通过心跳方式保持只有一台为主,当主设备出现故障时,由备用设备接管所有服务。分析表明,这个方案能很好地实现把私网地址复用的业务转移到融合承载网元,从而缓解IP地址不足的状况。With the rapid development of the mobile Internet business of ctwap, the original IP address space cannot meet the needs of the increasing volume of business. In view of the shortage of private network address, thus put forward the scheme of mobile core network construction carrying NAT network elements. In this scheme, the multiplexing use of private network address adopts a method of hanging CE beside the integrated carry network elements. CE forwards the business involved multiplexing use of private network address to the integrated carry network element for technical process of transformation and carry by the method of carry network CE transfer so as to complete the deployment of the pairs of comprehensive carry elements. When two sets of comprehensive carry network elements are working in the status of master and slave, only one of them keeps the status of master by the way of heartbeat. Once the master equipment breaks down, the standby equipment will take over all services.Analysis shows that this scheme can successfully realize transmission of the business of private network address multiplexing use to the integrated carry network elements so as to ease the shortage of IP address.
