Problems solved by technology

Similarly, when the group of MNs leaves N-MAG at the same time, it also needs to perform related operations for each MN, which obviously requires a large amount of signaling overhead and will definitely increase the handover delay

Embodiment Construction

[0050] The purpose of the present invention is to provide a PMIPv6 group switching solution based on link layer grouping. The method can effectively reduce the handover delay and signaling overhead when the MN switches from P-MAG to N-MAG in the form of a group, and is conducive to promoting the application of PMIPv6 in delay-sensitive services. The basic idea is: N-MAG obtains the IP address of P-MAG through the link layer, groups the MNs switched over according to the relevant information of P-MAG within the time interval ΔT, and registers or leaves with LMA in the form of groups; At the same time, this paper also proposes relevant solutions for the situation when the non-group leaves.

[0051] Below we take five MNs switching from P-MAG to N-MAG in groups as an example, and combine the attached Figure 9 Specific embodiments of the present invention will be described in detail.

[0052] 1. If Figure 9 As shown, the address of LMA is aec0:0:0:1::1 / 64, the address of P-MA...

Abstract

The invention relates to a proxy mobile IPv6 group switching solution based on link layer grouping. In particular, the invention aims at solving the problems as follows: in a proxy mobile IPv6 domain, when one group of MN (mobile nodes) is switched from the same P-MAG to another N-MAG, the group of MN can be registered in a form of group; when the MN leaves from the N-MAG, the MN can also be unbound and leave in a form of group. The purposes of the invention are realized as follows: the function of expanding MAG can group the MN based on the link layer, and maintain the grouping information until the MN leaves; the function of expanding LMA can record and maintain the grouping information; and the information formats defined by expansion RFC5213 like PBU, PBA and DeReg PBU can support the MN to be switched in the form of groups. The proxy mobile IPv6 group switching solution based on the link layer grouping can effectively reduce the switching signaling and signaling overhead when the MN moves in the form of groups, and is beneficial for promoting the application of PMIPv6 (proxy mobile internet protocol version 6) in time delay sensitive services.

Description

technical field [0001] The invention relates to the field of communication, in particular to a solution method for proxy mobile IPv6 group switching based on link layer grouping. Background technique [0002] In today's world, in the rapidly developing IT industry, the most eye-catching ones are mobile communication and Internet services. The crystallization of the integration of mobile communication technology and IP network---Mobile IP technology (MIP), accommodates the business in the global communication field. A notable feature of MIP is that the movement of the mobile node (MN) is transparent to the applications carried on the network layer. Simply put, it means that the MN moves between different networks, and the applications at the transport layer and above the transport layer do not need to be changed. The source address and destination address of the communication, so as to maintain the continuity of communication. The application of MIP technology has broad pro...
