Problems solved by technology

[0042] Existing technology 1 has the following two problems in the registration and deregistration of MNs in the mobile subnet: (1) When the entire subnet carried by the MR moves to a new LMA domain, the MNs in the MR need to perform register
If there are n MNs in the subnet, n registrations are required, which will increase signaling overhead and handover delay, and also increase the processing burden of MR and LMA
(2) Lack of solutions for deregistration of mobile subnets
[0044] In terms of MN registration and deregistration management within the mobile subnet, the existing technology 2 also has two problems of

Embodiment 1

[0100] The N-PMIPv6 mobile subnet registration and deregistration signaling process of applying the present invention is as follows Figure 14 shown.

[0101] Steps (A1), (A2): MAG1 establishes a BULE for MR1 after detecting the access of MR1, and sends a PBU containing MR-ID of MR1 and MSN-ID of the mobile subnet carried by MR1 to LMA for registration.

[0102] Step (A3): After receiving the PBU, the LMA extracts the MR-ID and MSN-ID of MR1, creates a BCE for MR1, and sends a PBA to MAG1, which contains the HNP information assigned to MR1. After the transmission is successful, the LMA establishes a tunnel and route for the HNP with MAG1 and LMA at both ends.

[0103] Step (A4): After receiving the PBA, MAG1 extracts the HNP in it, updates the BULE established by MR1, and then sends the RA containing the HNP to MR1. After the transmission is successful, MAG1 establishes a tunnel (MAG and LMA at both ends) and routing for HNP. After MR1 configures the address through H...

Embodiment 2

[0115] The N-NEMO mobile subnet registration and deregistration signaling process applying the embodiment of the present invention is as follows: Figure 15 shown.

[0116] Steps (B1)-(B4): Same as (A1)-(A4) in the N-PMIPv6 scenario.

[0117] Steps (B5), (B6): After MR detects the access of MN1, MR establishes a local binding update list entry (LBULE) for MN1, and records MN-ID, MSN-ID and other information in LBULE. Then the MR constructs an LPBU (B=0) containing the MN-ID and MSN-ID of MN1 and sends it to the MAG. The number of mobile nodes in the mobile subnet identifier option is set to 1.

[0118] Step (B7): After receiving the LPBU, MAG1 extracts the MSN-ID and MN-ID, creates a session for the MN-ID, and creates a local binding cache entry (LBCE) and BULE for MN1, and then sends the The MSN-ID and MN-ID of the GPBU to LMA1.

[0119] Step (B8): After receiving the GPBU, LMA1 extracts the MSN-ID and MN-ID, creates a BCE for MN1, extracts the MSN-ID and MN-ID, a...

Abstract

The invention discloses an agent mobile IPv6 signaling expansion, mobile subnetwork registering and deregistering method. The expansion method comprises the following steps that firstly, a subnetwork identifier is defined for showing that a plurality of MNs (mobile nodes) belong to a subnetwork so that MNs inside a mobile subnetwork are effectively managed in the mobile subnetwork registering and deregistering process, and in addition, the subnetwork identifier is registered when the MN identity is registered; next, during the mobile subnetwork registering, the signaling number during the registering is effectively reduced through the expansion of mobility options in PBU (proxy binding update) and PBA (proxy binding acknowledgement) messages; and finally, MSNRC (mobile subnet registration cache) is redefined on a MR (mobile router), the MNs inside the subnetwork are ranged according to sequences, and MN-ID (mobile node-identifier) and HNP (home network prefix) matching is ensured. The invention also discloses a mobile subnetwork registering and deregistering method.
