Problems solved by technology

[0010] 1. Unable to support pure 802 layer 2 terminals, RG / G-MS / G-RS must support the function of layer 3 gateway, which is complicated;
[0011] 2. Cannot support Layer 2 VPN (Virtual Private Network) and E2E VLAN (End-to-End Virtual Private Network);
[0012] 3. Unable to support PPPoE (Point-to-Point Protocol over Ethernet) / IPoE (IP over Ethernet);
[0013] 4. For the mixed use of IPv4 and IPv6 terminals, the network must support dual stack;
[0017] 1. It is required to "explicitly" send a registration message for each mobile node. For wireless networks, the air interface bandwidth is the main bottleneck of the network. When there are many MNs (mobile nodes), this method seriously wastes the air interface of the network. bandwidth resources;
[0018] 2. Mobile binding must bind the 802 MAC address of the MN with the IP address of the tunnel end point of the foreign subnet, and limit the tunnel to an IP tunnel;
[0019] 3. Proxy MN must be set on AP (access point);
[0020] 4. Only supports IPv4 mobility management

Embodiment 1

[0176] Embodiment 1 supports tunnel switching mode and double-layer tunnel mode. The Ethernet MAC frames of the MH and MB mobile networks traverse through the foreign network where the FA device is located to the home network where the HA device is located.

[0177] In the above-mentioned tunnel switching mode, the logical connection of IP is formed between the MB and the FA / PMIPv6 Client; the MIP tunnel is adopted between the FA / PMIPv6 Client and the HA; the Ethernet MAC layer of the MH and MB mobile network is located between the MB and the FA On the IP logical connection between / PMIPv6 Client and the MIP tunnel between FA / PMIPv6 Client and HA.

[0178] In the above two-layer tunnel mode, the tunnel between HA and MB is built on the tunnel between HA and FA / PMIPv6 Client; the Ethernet MAC layer of the MH and MB mobile network is located on the tunnel between HA and MB.

[0179] The structure of Embodiment 2 of the system of the present invention is shown in FIG. 3 . Inclu...

Embodiment 2

[0182] Embodiment 2 supports the CCOA mode. The Ethernet MAC frames of the MH and MB mobile networks traverse the home network where the HA device is located via the visited network where the MB device is located. A tunnel is built between HA and MB, and the Ethernet MAC layer of MH and MB mobile network is located on the tunnel between HA and MB.

[0183] The above-mentioned Embodiment 1 and Embodiment 2 are applicable to the multi-host architecture of an access network (such as DSL) or a WLAN network or a WIMAX (Worldwide Interactive Microwave Access) network. In the multi-host architecture of the WiMAX network, MH is G-Host, and MB is G-MS (gateway mobile station) / G-RS (gateway transfer station); in the multi-host architecture of WLAN network, MH is the host device Host, MB AP is the access point; in the multi-host architecture of the wired access network, MH is Host, and MB is RG / User Network Gateway CNG. The 802.16 between the G-MS / G-RS and the BS adopts the ETH CS (Eth...

Abstract

The apparatus comprises: FA (foreign agent) device, MB (mobile bridge) device, and HA (home agent) device. The method thereof comprises: the FA device establishes and maintains the layer two mobile binding, and sends a registration message carrying the 802 MAC address of MB device to HA device; according to the received registration message carrying the 802 MAC address of the MB device, said HA makes a layer two mobile binding for the MB device; by learning the MAC address, getting the 802 MAC address of MH; making a layer two mobile binding for the MH.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device, system and method for realizing Ethernet traversal mobile IP. Background technique [0002] A BWA (Broadband wireless access, broadband wireless access) device may provide a user with a convenient broadband access method. Currently, there are broadband wireless access devices based on proprietary protocols and broadband wireless access devices based on standard protocols. The broadband wireless access equipment defined by the IEEE (Institute of Electrical and Electronics Engineers) 802.16 standard is a subset of a series of standards for broadband wireless access technologies. BWA equipment includes WIMAX (Worldwide Interactive Microwave Access) equipment. [0003] A Multiple Hosts (multiple hosts) architecture in a wireless communication system is shown in FIG. 1 . When this architecture is applied to WiMAX system, the gateway in this architecture is G-MS (Gateway ...
