如何解决地址复用过程中引发的PMIP(代理的移动网际协议)用户漫游时引发的WAP(无线应用协议)业务订购时的费用张冠李戴问题,成为网络改造过程需要解决的首要难题。提出一种基于AAA(认证、授权和计费)系统和HA(归属代理)设备共同配合,为漫游的PMIP提供差异化地址分配策略,取消WAP网关上无效地址注册,确保一个WAP网关的用户地址具有唯一性,成功解决了费用张冠李戴问题。
How to solve the problem of WAP (Wireless Application Protocol) service subscription caused by PMIP (Proxy Mobile Internet Protocol) caused by address multiplexing during roaming, which becomes the primary problem that needs to be solved in the network transformation process. This paper proposes a cooperation strategy based on AAA (Authentication, Authorization and Accounting) system and HA (Home Agent) to provide differentiated address allocation strategy for roaming PMIP, cancel invalid address registration on WAP gateway, ensure the user address of a WAP gateway Unique, successfully solved the problem of costly.
