摘要
移动检测是支持移动终端进行切换的先决条件,数据完整性是移动终端在切换过程中不丢失分组的重要指标。针对WiMAX网络技术规范中基于IPv6的CSN锚点移动性管理场景的移动检测方案与IETF的移动检测方案不一致和切换过程中不能保证数据完整性的问题,提出了改进的增强型CSN锚点移动性管理方案。该方案没有增加新的网络实体和信令消息,解决了WiMAX规范和IETF规范在移动检测方面的兼容性,保证了CSN锚点移动性管理过程中的数据完整性,完善了CSN锚点移动性管理机制,提高了CSN锚点移动性管理性能。
Movement detection is the pre-conditions of a mobile terminal executing handoff, and data integrity is one of the important indexes of a mobile terminal carrying on handoff for the lossless packets. The movement detection in CSN anchored mobility management scenario based on IPv6 in the WiMAX network technology specification differs from that in IETF ing the CSN handoff. This paper proposes an improved , and the data integrity can＇ t be guaranteed durenhanced CSN anchored mobility management scheme resolving the aforementioned two problems. The scheme does not add a new network entity or a signaling message, solves the compatibility of the movement detection between the WiMAX specification and the IETF specification, guarantees the data integrity during the CSN anchored management,improves the management mechanism of CSN anchored mobility management, and enhances the performance of CSN anchored mobility management.
