IP移动性管理协议分为两大类：基于主机的移动性协议和基于网络的移动性协议。前一类，如MIPv6协议及其增强（例如，HMIPv6和FMIPv6）支持移动的节点（MN）的移动性以跨网络域漫游。这是通过MN参与移动性相关信令来完成的，这需要MN上的协议栈修改和IP地址改变。后一类，例如PMIPv6协议，代表MN处理移动性管理，从而使其能够在局部域内连接和漫游，这既不需要MN的协议栈修改也不需要MN的IP地址改变。PMIPv6通过改善MN的通信性能以满足实时服务的QoS要求，引起了互联网和电信界的关注。本文介绍了IPv6支持移动的系统的特性，综述了移动性管理服务沿着的技术、策略和协议种类，并对各种移动性管理协议进行了分类和比较。此外，它确定和讨论了移动管理面临的几个问题和挑战，沿着与几个相关的流动性研究的评价和比较。
IP Mobility management protocols are divided into two kinds of category: host-based and network-based mobility protocol. The former category, such as MIPv6 protocol and its enhancements (e.g., HMIPv6 and FMIPv6), supports the mobility of a Mobile Node (MN) to roam across network domains. This is done through the involvement of MN in the mobility-related signalling, which requires protocol stack modification and IP address changes on the MN. The latter category, such as PMIPv6 protocol, handles mobility management on behalf of the MN thereby enabling it to connect and roam within localized domains, which requires neither protocol stack modification nor IP address change of the MN. PMIPv6 attracts attention in the Internet and telecommunication societies by improving the performance of the MN's communication to fulfil the requirements of QoS for real-time services. In this article, we present IPv6 features to support mobile systems and survey the mobility management services along with their techniques, strategies and protocol categories, and elaborate upon the classification and comparison among various mobility management protocols. Furthermore, it identifies and discusses several issues and challenges facing mobility management along with an evaluation and comparison of several relevant mobility studies.
