Problems solved by technology

[0008] However, how to perform inter-domain handover in PMIPv6 is not covered in RFC5213. There is currently no authoritative method for how to maintain communication with the peer CN1 when the MN moves to another LMA

Embodiment Construction

[0063] The purpose of the present invention is to provide an inter-domain handover method of proxy mobile IPv6, which includes two cases of non-route optimization mode and route optimization mode. Below we combine Figure 8 The specific process of the inter-domain handover of proxy mobile IPv6 is introduced in detail.

[0064] 1. The method of PMIPv6 inter-domain handover in non-route optimization mode

[0065] We assume that MN initiates communication to CN1 through MAG1 and LMA1, and the address of LMA1 is aec0:0:0:1::1 / 64. At this time, the address of MAG1 is cec0:0:0:1::1 / 64, and MAG1 Assign an address Proxy-CoA1 to the MN, and Proxy-CoA1 is the address of MAG1. LMA1 assigns a home address network prefix MN-HNP1 to MN, and establishes the binding between MN-HNP1 and Proxy-CoA1 in LMA1, MN configures address HoA1 according to MN-HNP1, and HoA1 is aea0:0:0:1: :2 / 64, and use HoA1 as the home address in the communication with CN1. The address of CN1 is eec0:0:0:1::1 / 64. A...

Abstract

The invention relates to an inter-domain switching method of a proxy mobile IPv6 (Internet Protocol Version 6). When a mobile node (MN) is switched from a local mobile anchor (LAM1) to the other local mobile anchor (LAM2), a binding of a former home address (HoA1) and a new home address (HoA2) is established on the LMA1 by the MN. In a non-routing optimization mode, a source address of a data report which is sent to a non-switched communication node (CN) by the switched MN is the HoA1, and a purpose address of the data report which is sent to the MN by the CN is the HoA1. Therefore, the communication between the MN and the CN is transferred through the LMA1. In a routing optimization mode, an address binding which is maintained by the switched CN is changed to a binding of the HoA1 and the HoA2, the source address of the data report which is sent to the CN by the MN is changed to the HoA2, a home address item expansion head is filled with the HoA1, the purpose address of the data report which is sent to the MN by the CN is changed to the HoA1, and a second kind route head is filled with the HoA1. Accordingly, the CN and the MN can directly be communicated with each other.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for agent mobile IPv6 inter-domain switching. 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 prospects, and its development has be...
