Embodiment 1
[0120] Embodiment 1. Network initialization R3Re-anchor optimization method triggered by MS mobility event based on PMIPv4 protocol
[0121] Such as Figure 8 As shown, steps 1-6 are the same as those of the prior art, and for a detailed description, refer to the section on the background technology Figure 5 The description will not be repeated here, and the comparison Figure 5 Visible, the present invention has carried out following optimization in the network initialization R3 Re-anchor process that the MS mobility event of existing PMIPv4 agreement triggers:
[0122] 7. The HA sends a MIP Registration Reply message to the Target FA, which carries the sequence number X of the first data packet that the HA will send to the Target DP Function through the newly created R3 link;
[0123] 8a. After the Target FA receives the MIP Registration Reply, it sends a Trigger message to the Target Data Path Function, which carries the serial number X;
[0124] 8b. When the Target Data ...
Embodiment 2
[0133] Embodiment 2. Network initialization R3 Re-anchor optimization method triggered by MS mobility of CMIPv4 protocol
[0134] Such as Figure 9 As shown, steps 1-5 are the same as those of the prior art, and for a detailed description, refer to the section on the background technology Figure 5 The description will not be repeated here, and the comparison Image 6 It can be seen that the present invention increases or optimizes the following steps on the basis of the network initialization R3 Re-anchor process triggered by the MS mobility time of the existing CMIPv4 protocol:
[0135] 6. The HA sends a MIP Registration Reply message to the Target FA, which carries the sequence number X of the first data packet that the HA will send to the Target DP Function through the newly created R3 link;
[0136] 7a. After the Target FA receives the MIP Registration Reply, it sends a Trigger message to the Target Data Path Function, which carries the serial number X;
[0137] 7b. Wh...
Embodiment 3
[0144] Embodiment 3. Network initialization R3 Re-anchor optimization method triggered by MS mobility of CMIPv6 protocol
[0145] In the case of IPv6, when the Target AR receives the Binding Update Confirmation (BU Confirmation), it triggers the Target Data Path Function to ask the Anchor Data Path Function whether the data has been sent. If it has been sent, then start the following process. If not After sending, wait for the Anchor DataPath Function to send the cached data before proceeding to the subsequent process.
[0146] Such as Figure 10 As shown, steps 1-7 are the same as those of the prior art, and for a detailed description, refer to the section on the background technology Figure 7 The description will not be repeated here, and the comparison Figure 7 It can be seen that the present invention adds or optimizes the following steps on the basis of the network initialization R3 Re-anchor process triggered by the MS mobility time of the existing CMIPv6 protocol: ...
