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 session peer when the MN moves from one LMA to another

Embodiment Construction

[0074] The invention proposes a network mobility-based proxy mobile IPv6 inter-domain switching method. Describe the implementation method of this invention in detail below.

[0075] We assume that A_MN establishes a session with B_MN through A_LMA1, and B_MN establishes a session with A_MN through B_LMA1.

[0076] The information recorded in the corresponding entry of the "Mobility Management Table" of A_LMA1 is:

[0077] ●Home address of A_MN: A_HoA1

[0078] ●The care-of address of A_MN: A_HoA1

[0079] ●Home address of B_MN: B_HoA1

[0080] ●B_MN's care-of address: B_HoA1

[0081] ● Proxy-CoA: A_Proxy-CoA1

[0082] The information recorded in the corresponding entry of B_LMA1 "Mobility Management Table" is:

[0083] ●Home address of B_MN: B_HoA1

[0084] ●B_MN's care-of address: B_HoA1

[0085] ●Home address of A_MN: A_HoA1

[0086] ●The care-of address of A_MN: A_HoA1

[0087] ● Proxy-CoA: B_Proxy-CoA1

[0088] We make the following settings:

Abstract

The invention provides an agent mobile IPv6 (Internet Protocol Version 6) inter-domain switching method based on network mobility management. The traditional agent mobile IPv6 method is not suitable for inter-domain switch. Compared with the traditional agent mobile IPv6 method, the method provided by the invention expands structures and kinds of signalling messages, re-defines concepts of home addresses and care-of addresses, increases cache information of local mobility anchors and re-assigns processes for communicating and updating. The method provided by the invention realizes the four targets as follows: firstly, consistent idea of the agent mobile IPv6 is followed; mobile subscribers do not participate in any mobility management work; and mobility management works are responsible by network equipment, such as local mobility anchors; secondly, mobility (inter-domain switching) of the mobile subscribers is completely transparent on a conversation opposite side; thirdly, routing is optimized, namely, both conversion sides directly communicate through the local mobility anchor which is currently accessed without communicating bypassing the local mobility anchor before switching; and fourthly, in the process of carrying out inter-domain switching, the method is completely compatible with the traditional agent mobile IPv6 method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for agent mobile IPv6 inter-domain switching based on network mobility management. 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 ...
