Embodiment 1
[0061] Such as Figure 4aAs shown, it is a method for implementing PMIP6 route optimization provided by the embodiment of the present invention. In this embodiment, the route optimization is started according to the trigger message sent by the MN, and the MAG executes the RRP process. The MN can communicate with one CN, or communicate with multiple CNs at the same time. When the MN communicates with multiple CNs at the same time, the route optimization trigger message may include the CN information to be optimized. If the CN information is not included, it is defaulted that all CNs communicating with it need to perform route optimization.
[0062] The route optimization process includes the following steps:
[0063] S401. The MAG receives the route optimization trigger message sent by the MN, and the route optimization trigger message indicates the start of the route optimization process;
[0064] S402-S403, the RRP process is performed between the MAG and the CN;
[0065]...
Embodiment 2
[0078] This embodiment is the same as the routing optimization triggering and CoA binding update process of the first embodiment, the only difference is that the RRP process is executed by the PMIP client. Among them, there are two ways to implement the handover test process:
[0079] The first implementation of the handover test process includes steps: the PMIP client encapsulates the CoTI message in the signaling inside the ASN and sends it to the MAG, the MAG sends the CoTI message directly to the CN, and the CN directly returns the CoT message to the MAG, and the MAG performs Data filtering, encapsulating the obtained CoT message in the signaling and sending it to the PMIP client;
[0080] The second implementation of the handover test process includes steps: the PMIP client directly routes and sends the CoTI message that includes the Alternate CoA, the CoTI message can set the proxy flag or include the AlternateCoA, if the PMIP client and the MAG are in the same physical ...
Embodiment 3
[0101] In this embodiment, the backhaul routable process in Embodiment 1 and Embodiment 2 is optimized to simplify the backhaul routable process. Specific optimization may include the following two types of processing, and these two types of optimization processing may be applied simultaneously in practical applications, or only one of them may be applied.
[0102] 1. Optimization of the home testing process
[0103] The home test procedure in embodiment 1 and embodiment 2 is optimized, for the MN that communicates with the same CN through the same HA and the same CN by the same MAG proxy data, can only execute the home test process once, that is to say, each The home test process is initiated for all MNs with the same MAG proxy data, belonging to the same HA, and communicating with the same CN. All MNs with the same MAG proxy data, belonging to the same HA, and communicating with the same CN can reuse a home keygen token. At this time, in order to ensure the versatility of t...
