Abstract

The invention discloses a quick and efficient agent mobile IPv6 switching method. By the adoption of a make-before-break prediction mode in the method, access authentication and registration updating processes in the PMIPv6 switching process are completed before a current link breaks, so that after a mobile node is connected to a new link, ports can be configured as soon as possible and the communication session process can be continued, therefore, switching delay is shortened, and packet losses are lowered. Meanwhile, according to the provided switching method, the condition that the prediction mode fails is also considered, a self-adaptive link triggering mechanism is used, namely preparation operations are triggered and switched in a dynamic mode according to the movement speed of the mobile node and the time required for switching the preparation operations, it is guaranteed that the prediction mode is conducted successfully, and therefore the reliability of the method is enhanced.

Description

technical field

[0001] The invention relates to the technical field of wireless network multimedia communication, in particular to a fast and effective proxy mobile IPv6 switching method. Background technique

[0002] Proxy Mobile IPv6 (PMIPv6) is a network-based local mobility management mechanism standardized by the IETF NETLMM working group in 2008. In PMIPv6, the mobile node does not need to participate in any signaling interaction process related to IP mobility, so the wireless link tunnel overhead and signaling overhead are greatly reduced. However, since PMIPv6 adopts the reactive mode of "break first, then connect", the operations of access authentication, registration, and tunnel establishment during the handover process bring about large delays and packet loss problems during the handover process. It is unacceptable for instant messaging and multimedia applications with higher real-time requirements.

[0003] In order to reduce the handover delay brought by PMIPv...
