摘　　要：针对在传统移动IP中用户只能被动使用已知的网络服务问题,提出了支持主动式网络服务发现的移动IP方案.本方案在传统移动IP基础上,引入基于客户/服务模型的主动服务发现机制,并制定具体的通信过程及各种消息的格式,实现了对瘦客户的支持.同时针对带宽紧张问题,设计了优化过滤机,实行结果过滤,避免了不必要的结果的发送,提高了带宽利用率.模拟实验表明了该系统较好地支持了移动IP中主动服务发现,具有较好的实用性和应用价值.The IETF Mobile IP standard is intended to solve the general problem of host mobility in the global Internet. The framework guarantees the hosts in Internet should not change their home address and keep the transparency over IP layer during the movement in different networks. But when a host moves to a foreign network, it becomes difficult for the host to actively find the requested services in the new environment. The paper proposes the active service discovery scheme in mobile IP, which is based on SLP. In our project, we design the client/service model and set the concrete communication process and all messages’ format. It also supports thin client and designs the preference filter, which can filter the unnecessary results to spare the band.
