摘要：

针对传统IP寻呼（IP paging）方法存在的寻呼“信令风暴”问题，提出了一种采用分布式寻呼策略的链式IP寻呼方法，提高IP寻呼的灵活性和扩展性。该方法在层次型移动IPv6 （HMIPv6）网络的移动节点中引入半激活（semi-active）状态，通过动态地指定寻呼代理和建立寻呼链，减少寻呼消息数量，实现信令负载分担。采用Fluid Flow移动模型建模分析表明，通过合理控制寻呼链长度，链式IP寻呼方法可以明显减小寻呼信令开销，改善网络整体性能。

Abstract:

A distributed link-based IP paging method is proposed to enhance the scalability and flexibility of traditional IP paging. A semi-active state of mobile node (MN) is introduced in hierarchical mobile IPv6 (HMIPv6) network. Then, a dynamic paging agent (PA) designation and paging link establishment approach is proposed, it would decrease the number of redundant IP paging messages and balance the network signaling traffic. Theoretical analysis for overall signaling load demonstrates that the link-based paging method with moderate paging link length could significantly reduce the paging signaling cost and improve the network performance.

Key words: IP paging, hierarchical mobile IPv6, location management
