HA发送包含有 "绑定更新" 目的选项的数据包, HA登记该绑定并且向 MS/G-Host返回一 个包含有 "绑定确认" 目的选项的数据包。 HA截取所有地址为该 MS/G- Host的家乡地址 的数据包,每个截获的数据包都使用 IPv6封装并采用隧道技术发送到移动节点所登记的 转交地址。 现有技术一种上述 WIMAX IPv6网络中的通信节点间通信的方法为: 如果一个通信节 点要与另一个离开家乡网络的 MS/G- Host通信, 数据包的选路过程是: 从该通信节点到 HA, 从 HA到 MS/G-Hos1:, 再从 MS/G- Host到另一个离开家乡网络的通信节点。 这种路由方 式通常称为三角路由。 为了避免三角路由问题, MS/G-Host可以发送携带当前的 CoA的绑 定更新给任意一个通信节点, 该通信节点将上述绑定更新上携带的当前的 CoA缓存起来 并直接发送数据包给 MS/G-Host。 HA sends a packet containing the "Binding Update" destination option, and HA registers the binding and returns a packet containing the "Binding Confirmation" destination option to MS/G-Host. The HA intercepts all data packets whose addresses are the home address of the MS/G-Host, and each intercepted data packet is encapsulated in IPv6 and transmitted to the care-of address registered by the mobile node by using tunnel technology. A method for communication between communication nodes in the above WIMAX IPv6 network is as follows: If a communication node is to communicate with another MS/G-Host leaving the home network, the routing process of the data packet is: from the communication node Go to HA, from HA to MS/G-Hos1:, then from MS/G-Host to another communication node that leaves the home network. This type of routing is often referred to as a triangular route. In order to avoid the triangle routing problem, the MS/G-Host may send a binding update carrying the current CoA to any communication node, and the communication node caches the current CoA carried on the binding update and directly sends the data packet to the MS. /G-Host.
上述方法的缺点为:  The disadvantages of the above methods are:
1、 该方法要求 MS必须实现 Mobile IPv6, 不能采用仅支持 Simple IPv6 (简单 IPv6) 的 MS, 导致 MS功能复杂;  1. This method requires that the MS must implement Mobile IPv6, and cannot use MS that only supports Simple IPv6 (Simple IPv6), resulting in complex MS functions;
2、 该方法需浪费空口资源进行 CoA登记;  2. This method requires waste of air interface resources for CoA registration;
3、 由于 3G网络 (如 WCDMA) 不支持 CMIPv6, 根据该方法进行通信使 WiMAX和 3G网络 (如 WCDMA) 的互连成为问题;  3. Since 3G networks (such as WCDMA) do not support CMIPv6, communication according to this method makes the interconnection of WiMAX and 3G networks (such as WCDMA) a problem;
4、 由于通常 G-Host和 G- MS/G-RS为设置在火车、 汽车或轮船上的移动网络, G- Host 往往是相对于 G- MS/G-RS固定的乘客所使用的终端, 一般不能实现 Mobile IPv6功能, 从 而使该方法无法在现有的 WiMAX移动 Multihost网络中使用。 发明内容  4. Since G-Host and G-MS/G-RS are usually mobile networks set up on trains, cars or ships, G-Host is often used as a terminal for fixed passengers relative to G-MS/G-RS. Mobile IPv6 functionality is generally not implemented, making this method inaccessible to existing WiMAX mobile Multihost networks. Summary of the invention

下面结合附图来详细描述本发明实施例所述方法。  The method of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
在 PMIPv6信令面处理方面, 一种基于 DHCPv6 (动态主机配置协议 IP v6 ) 的 PMIPv6 用户连接建立过程的流程如图 7所示, 其中 HA在 V- NSP (拜访地网络服务提供商) , 对于 HA在 H- NSP (归属地网络服务提供商)场景, 只需将图 7中的 V- AAA去掉即可。  In the PMIPv6 signaling plane processing, a process of establishing a PMIPv6 user connection based on DHCPv6 (Dynamic Host Configuration Protocol IP v6) is shown in Figure 7, where HA is in V-NSP (visiting network service provider), HA in the H-NSP (Home Network Service Provider) scenario, just remove the V-AAA in Figure 7.
图 7所示的 PMIPv6用户连接建立过程的流程包括如下步骤:  The process of the PMIPv6 user connection establishment process shown in Figure 7 includes the following steps:
步骤 71、 接入认证。  Step 71: Access authentication.
在接入认证过程中, 决定网络是否给丽分配 HoA; PMIPv6 Client通过同顧(包括 MS 或 G-Host ) 的 H- AAA进行 AAA接入认证消息交互获得 AAA密钥、 HA地址、 以及 HoA或 DHCP server地址。  In the access authentication process, it is determined whether the network assigns HoA to the MN; the PMIPv6 Client obtains the AAA key, the HA address, and the HoA or the AAA access authentication message through the H-AAA of the MS (including the MS or the G-Host). DHCP server address.
步骤 72、 自动配置 LLA ( link-local address, 链路-局部地址)和 DAD (重复地址 探测) 。  Step 72: Automatically configure LLA (link-local address) and DAD (duplicate address detection).
讀到 PMIPv6 Client之间数据通路一旦建立, MN开始进行 LLA自动配置; MN进行 LLA 自动配置后,发起 Neighbor Solicitation消息,对 LLA进行 DAD, Neighbor Solicitation 消息中包含 tentative (实验性) LLA。 PMIPv6 Client支持 LLA的 Proxy DAD (代理 DAD),建立和维护所代理的丽 IP Address Cache , ΡΜΙΡνβ Client可以从剛的 Neighbor Solicitation消息学习應的 LLA; ΡΜΙΡνβ Client将 tentative LLA和 Address Cache中的地址进行比较; 如果存在匹配, 则代替匹 配地址拥有者发送 Proxy Neighbor Advertisements消息; 如果不存在匹配, 则仅将 tentative LLA力口入 Address Cache。 After reading the data path between the PMIPv6 Clients, the MN starts the LLA automatic configuration. After the MN performs the LLA auto-configuration, it initiates a Neighbor Solicitation message, performs DAD on the LLA, and contains a tentative (experimental) LLA in the Neighbor Solicitation message. The PMIPv6 Client supports the Proxy DAD (Proxy DAD) of LLA, establishes and maintains the proxy IP Address Cache, and the ΡΜΙΡνβ Client can learn the appropriate LLA from the Neighbor Solicitation message; ΡΜΙΡνβ Client compares the addresses in the tentative LLA and the Address Cache. If there is a match, the Proxy Neighbor Advertisements message is sent instead of the matching address owner; if there is no match, only the tentative LLA is forced into the Address Cache.
步骤 73、 DHCP server配置。  Step 73: DHCP server configuration.
如果 Authenticator在上述步骤 71中得到了 DHCP server地址, 则 DHCP Proxy/Relay 可从 Authenticator下载 DHCP server地址和 MN标识 (MAC地址) ; DHCP Proxy/Relay也 可以静态配置 DHCP server地址, 执行步骤 74 -步骤 77; 否则, 执行步骤 78-步骤 79。 步 骤 74-步骤 77、 IP地址分配和 IP主机配置。  If the Authenticator obtains the DHCP server address in step 71 above, the DHCP Proxy/Relay can download the DHCP server address and the MN identity (MAC address) from the Authenticator; the DHCP proxy/Relay can also statically configure the DHCP server address, and perform step 74 - Step 77; Otherwise, perform steps 78-79. Step 74 - Step 77, IP Address Assignment and IP Host Configuration.
在 PMIPv6方案中, 丽对 IP移动是透明的, 丽利用 DHCPv6进行 MN HoA分配和 IP主机配 置; MN发起 DHCPv6 Solicit消息, 以发现可用的 DHCP server; 在收到 DHCP v6 Solicit 消息后, DHCP Proxy/Relay将消息中转给 DHCP server ? 任何能够满足 MN要求的 DHCP server都可以回应 DHCP v6 Advertise消息给 DHCP Proxy/Relay; DHCP Proxy/Relay中 转 DHCP v6 Advertise消息给丽; MN选择合适的 DHCP server, 然后发送 DHCP v6 Request 消息经由 DHCP Proxy/Relay给 DHCP Server; DHCP Server生成 DHCPv6 Reply消息, 内含 HoA和 IP主机配置选项, 发给 DHCP ProXy/Relay。 图 7中的虚框中的步骤为可选步骤。 In the PMIPv6 scheme, MN is transparent to IP mobility, MN uses DHCPv6 for MN HoA allocation and IP host configuration; MN initiates DHCPv6 Solicit message to discover available DHCP server; after receiving DHCP v6 Solicit message, DHCP Proxy/ Relay relays the message to the DHCP server. Any DHCP server that can meet the MN requirements can respond to the DHCP v6 Advertise message to the DHCP Proxy/Relay; DHCP Proxy/Relay relays the DHCP v6 Advertise message to the MN; the MN selects the appropriate DHCP server, and then sends The DHCP v6 Request message is sent to the DHCP server via DHCP Proxy/Relay; the DHCP Server generates a DHCPv6 Reply message, which contains the HoA and IP host configuration options and sends it to the DHCP Pro X y/Relay. The steps in the virtual box in Figure 7 are optional steps.
或者,  Or,
MN发送 DHCPv6 Solicit 消息; DHCP Proxy/Relay回应 DHCPv6 Advertise消息给丽; 應回应 DHCPv6 Request消息给 DHCP Proxy/Relay。  The MN sends a DHCPv6 Solicit message; the DHCP Proxy/Relay responds to the DHCPv6 Advertise message to the MN; it should respond to the DHCPv6 Request message to the DHCP Proxy/Relay.
执行步骤 78-步骤 79。  Perform steps 78-79.
步骤 78-步骤 79。  Steps 78 - 79.
对于 ASN/G-MS/G- RS支持 PMIPv6和 CMIPv6双模的情况, DHCP Proxy/Relay通过 R3— Mobility— Context消息通知 ASN Fn所采用的 MIP模式; 若 ASN/G- MS/G- RS只支持 ΡΜΙΡνδ, 该步骤可省略;  For ASN/G-MS/G-RS supporting PMIPv6 and CMIPv6 dual mode, DHCP Proxy/Relay notifies ASN Fn of the MIP mode through R3_Mobility_Context message; if ASN/G-MS/G-RS only Support ΡΜΙΡνδ, this step can be omitted;
步骤 710、 CoA生成。  Step 710: CoA is generated.
ΡΜΙΡνθ Client从 LLA中抽取 interface identifier (接口标识) , 将其附加在所在 AR广播给 CMIPv6节点的前缀之后, 生成丽的 CoA; PMIPv6 Client也可以用所在 AR的 IP地址作为 MN的 CoA, 即 PMIPv6 Client代理的不 同 MN将使用同一个 CoA, 这会对 HA带来额外的要求, 要求 HA不能支持对 MN进行 CoA唯一性 检查。 ΡΜΙΡνθ Client extracts the interface identifier from the LLA and appends it to the prefix that the AR broadcasts to the CMIPv6 node to generate the CoA of the MN; The PMIPv6 client can also use the IP address of the AR as the MN's CoA. That is, the different MNs of the PMIPv6 Client proxy will use the same CoA. This will impose additional requirements on the HA, and the HA cannot support the CoA uniqueness check on the MN.
步骤 711-步骤 712。  Step 711 - Step 712.
DHCP Proxy /Relay在以上述 DHCPv6或 AAA的方法取得了 HoA后, 通过 HoA_Address primitive (源语) 将 HoA发送到 PMIPv6 Client, HoA一 Address源语中包含 MN标识 (MAC 地址) 。  After obtaining the HoA by the DHCPv6 or AAA method, the DHCP Proxy/Relay sends the HoA to the PMIPv6 Client through the HoA_Address primitive. The HoA-Address source contains the MN identifier (MAC address).
步骤 713-步骤 716、 MIPv6注册  Step 713 - Step 716, MIPv6 registration
在麵的 CoA生成和 HoA取得之后, PMIPv6 Client就可以发起 MIPv6 BU (注册消息) , MIPv6 BU包括如下信息:  After the CoA generation and HoA acquisition, the PMIPv6 Client can initiate MIPv6 BU (registration message). The MIPv6 BU includes the following information:
1、 薩的 HoA;  1. Sa's HoA;
2、 丽的 CoA;  2, Li's CoA;
3、 Security credentials (安全资料) , 如 MN- AAA认证移动选项。  3. Security credentials, such as MN-AAA authentication mobile options.
HA回应绑定确认消息给 PMIPv6 Client;  The HA responds with a binding confirmation message to the PMIPv6 Client;

Security credentials, such as MN-AAA authentication mobile options. The HA needs to support the ProA DAD of the HoA (the proxy DAD); after the HA completes the DAD instead of the MN, it responds to the binding confirmation message to the PMIPv6 Client; Step 85-Step 86, this step is optional, and is sent in the PMIPv6 Client when the initial connection is established. After the MIPv6 registration message is sent to the HA, the HA obtains the MN-HA key and the PMIPv6 Client-HA key by interacting with the H-AAA before the HA responds to the binding confirmation message to the PMIPv6 Client. Step 89 - Step 810, Router Discovery. The MN initiates an RS (Router Solicitation) message, and requests the RA (Router Advertisement) message of the AR where the PMIPv6 client is located to learn the on-link prefix. ΡΜΙΡνβ The AR where the client is located after the MIPv6 registration succeeds (the HoA has passed the Proxy DAD of the HA), The MN sends an RA message carrying the HL prefix, and continues to learn the HL prefix according to the RA message.
或者,  Or,
PMIPv6 Client所在 AR在完成 MIPv6注册后, 主动向 MN发送携带 HL前缀的 RA消息, MN根据该 RA消息学习到 HL前缀。 步骤 811、 自动配置 HoA/DHCPv6配置。 After the MIPv6 registration is complete, the AR of the PMIPv6 client sends an RA message carrying the HL prefix to the MN.
