Embodiment 1

[0182] Embodiment 1: The visited network supports IPv4, and the mobile resident network supports IPv6 and IPv4

[0183] This embodiment supports two modes: Coexistence Care-of-Address (CCOA) mode and Foreign Agent Care-of-Address (FACOA) mode, and these two modes will be described respectively below.

[0184] 1. FACOA mode

[0185] figure 2 It is a dual-stack NEMO functional block diagram of a multi-host access system supporting hybrid IP in the FACOA mode in this embodiment. Such as figure 2 As shown, the system of the present invention includes: mobile router MR, dual-stack agent network mobile version 4 client (optional), foreign agent FA, dual-stack HA equipment (including HA and mobile binding data storage), authenticator and AAA ( authentication, authorization, accounting) server. in:

[0186] The dual-stack proxy network mobile version 4 client (Proxy NEMOv4 Client, referred to as the dual-stack proxy NEMOv4 client), can be optionally set on the network side (netwo...

Embodiment 2

[0281] Embodiment 2: The visited network supports IPv6, and the mobile resident network supports IPv4 and IPv6

[0282] The present invention proposes a dual-stack NEMO scheme, and its functional block diagram can still be adopted Figure 4 , there is no dual-stack proxy NEMO client and FA in this embodiment. Therefore, MR needs to support dual-stack NEMO customer control plane and data plane functions.

[0283] (1) MR needs to support the functions of the dual-stack NEMO client control plane:

[0284] 1. Support the functions of the NEMOv6 client control plane in the existing technology;

[0285]2. Support the IPv6 registration function based on IPv4 network prefix binding, that is, the dual-stack NEMO Client can initiate an IPv6 registration request, including the IPv4 network prefix of the MR and MH networks and the CoA of the MR; this can be done through the IPv6 binding update (Binding Update ) message by adding an IPv4 network prefix extension, which contains the IPv4...

Embodiment 3

[0315] Embodiment 3: Part of the visited network supports IPv4, and the FA and mobile resident network support IPv6

[0316] The functional block diagram of Embodiment 3 of the present invention is as Figure 7 shown. Part of the visiting network supports IPv4, and the FA and mobile resident networks support IPv6.

[0317] Set up a dual-stack Proxy NEMO Client (proxy NEMOv4 client) on the NAP, which is used to proxy the MR and MH networks to perform the functions of the dual-stack NEMO client control plane:

[0318] 1. Support the functions of the NEMO customer control plane in the existing technology;

[0319] 2. Support the IPv4 registration function based on IPv6 network prefix binding, that is, the dual-stack Proxy NEMO Client can initiate an IPv4 registration request, including the IPv6 network prefix of the MR and MH networks, the IPv6 HoA of the MR and the CoA of the MR; this can be registered through the IPv4 The request message adds IPv6 network prefix extension an...

Abstract

The present invention provides a method, a system and a device that support the hybrid IP multi-host access, wherein the device includes a mobile router device, a non-local agent device and a double-stack home agent device. The mobile router device is used to connect a customer premise network with a visited network and represents the network of mobile routers (MR) and mobile nodes (MN) to perform the function of the data plane of mobile customers in an IPv4 and IPv6 double-stack network; the non-local agent device represents the network of mobile routers (MR) and mobile nodes (MN) to perform the control plane of the mobile network customers, initiates IPv4 registration requests based on the IPv6 network prefix and acts as a non-local agent of mobile nodes (MN) and mobile routers (MR) to retransmit the IPv4 registration requests; the double-stack home agent device acts as a home agent of mobile nodes (MN) and mobile routers (MR), responds to the IPv4 registration requests coming from the non-local agent device, establishes the binding of the IPv6 network prefix of the network of MRs and MNs and the home addresses of IPv4 or IPv6 of MRs and correspondingly establishes the binding of the home addresses of IPv4 or IPv6 of MRs and the care-of addresses of MRs.

Description

technical field [0001] The present invention relates to mobile IP technology, and specifically relates to a multi-host access method, system and equipment supporting hybrid IP. Background technique [0002] In the existing multiple hosts (Multiple Hosts) architecture (such as figure 1 shown), including host, gateway (G-MS / G-RS / RG / CNG), access service network (ASN) and connection service network (CSN). Among them, ASN provides wireless access for users, and CSN provides IP connection for users. A Network Access Provider (NAP) is an operating entity that provides wireless access equipment for one or more Network Service Providers (NSPs). A NAP can own one or more ASNs. NSP is also an operating entity, providing services such as IP connection and WiMAX for users, and the equipment of NSP is located in the CSN. exist figure 1 Among them, for a WiMAX network, the gateway is G-MS / G-RS; for a wired network (such as a DSL network), the gateway is a resident gateway RG, a routing...
