- HoA Home Address
- the MN moves to the field
- an address is obtained from the foreign network, called CoA (Care-of Address)
- the MN sends a binding update with the CoA to the HA (Home Agent, Home Agent;), on the HA.
- the HA encapsulates the IP (Internet Protocol) text that needs to be forwarded to the MN.
- the source address of the outer packet is the address of the HA.
- the destination address is CoA.
- the HA advertises the encapsulated packet to the tunnel.
- the MN uses the CoA to send the packet.
- the source address of the outer layer is CoA
- the destination address is the address of the HA

- ⁇ (Proxy Mobile Internet Protocol Version 6, Proxy Mobile Internet Protocol version 6)
- Ten is an extension of MIPv6 (Mobile Internet Protocol Version 6, Mobile Internet Protocol Version 6): MAG (Mobile Access Gateway, Mobility)
- the access gateway simulates the home link, and advertises the HNP (Home Network Prefix) to the MN, so that the MN thinks that it is always on the home link; the MAG replaces the MN and sends it to the LMA (Local Mobility Anchor). Registration
- the LMA is equivalent to the HA function in MIPv6.
- a binding cache entry is established on the LMA for the home network prefix and the MAG interface address (Proxy-CoA), and a bidirectional tunnel is established between the MAG and the LMA for transmitting the MN.
- the process of sending and receiving the text is as follows:
- the peer node sends a packet to the home address of the mobile node, and the packet is intercepted by the LMA. Then, the LMA queries the binding list according to the home prefix, and then sends the packet to the MAG through the tunnel between the LMA and the MAG. After encapsulation, the packet is sent to the MN according to the destination address of the packet.
- the MAG receives the packet for encapsulation, adds the outer packet (including the source address), and then sends the packet to the LMA through the tunnel between the MAG and the LMA. The outer packet forwards the inner packet to the peer node.
- the MN accesses the network.
- the message returned to the MAG includes the configuration information of the MN, such as the LMA address, and the NAI of the MN (Network Access Identity network access). Mark) and so on.
- MAG proxy The MN sends a PBU request to the LMA.
- the LMA returns PBA (Proxy Binding Acknowledge), with the home prefix of MN.
- the MAG sends an RA (Route Advertisement) to the MN, and informs the MN's home prefix.

- Step 205a when the MAG receives the proxy binding update failure message, it will verify or select LMA2. If the PBA message carries the redirected LMA2 address, the MAG verifies the LMA2 address, which includes: comparing with the LMA address of the MN configuration document; or by interacting with the AAA server, the AAA server verifies the LMA2 address. If the PBA message does not have an LMA2 address or LMA1 has no response, etc., the MAG selects LMA2 from the MN configuration (selection or polling according to priority order), or from AAA service. retrieve an LMA2 address in the server.
- Step 206a the MAG proxy MN registers, and sends a PBU request to the LMA2.
- Step 207a LMA2 confirms that the registration is successful, and sends a PBA message to the MAG with the home network prefix assigned to the MN.
- the MAG sends an RA to the MN to notify the MN of the home network prefix.

本发明实施例中 PMIP系统结构如图 la所示, 配置或部署有多 个 LMA 101 ,各个 LMA 101之间支持网络共享、负载均衡; MAG 102
与 LMA 101之间存在多对多连接; AAA服务器 103为 MN接入过程 中认证授权, 同时保存或获取 MN的配置信息。 图 la所示的 PMIP 系统是一个逻辑框架系统, 该系统可以应用到 WiMAX ( Worldwide Interoperability for Microwave Access ,微波存取全球互通)标准、 3 GPP ( 3rd Generation Partnership Project, 第三代合作伙伴计划)标准、 3GPP2标准等中的网络架构。 例如, 当应用到 WiMAX标准中时, MAG可以位于 WiMAX的接入服务网络的接入网关上; 而 LMA位 于 WiMAX的连接服务网络中, 可以与支持 PMIP功能的 HA共存。 在 PMIP系统中移动性管理可以仅作为控制功能,与数据路由分离开, 例如, 一种 NGN的参考架构如图 lb所示, 包括: C-MMCF ( Central Mobility Management Control Function , 中心移动性管理控制功能), 位于 NGN 网给的核心网; A-MMCF ( Access Mobility Management Control Function,接入移动性管理控制功能),位于 NGN网络的接入 网。 上述 LMA、 MAG分别指 C-MMCF、 A-MMCF„ MMCF还可以 进一步细分为 LMF ( Location Management Function, 位置管理功能) 和 HCF ( Handover Control Function, 切换控制功能)。 上述 LMA、 MAG分别指 C-LMF ( Central Location Management Function, 中心位 置管理功能)、 A-LMF ( Access Location Management Function, 接入 位置管理功能), 和 /或 C-HCF ( Central Handover Control Function, 中心切换控制功能)、 A-HCF ( Access Handover Control Function, 接 入切换控制功能)。
基于上述系统, 下面将通过具体的实施例来描述, MAG如何选 择 LMA, 并进行 PBU注册, 直至发送注册结果( MN的家乡网络前 缀 )给 MN, 完成 MN的接入注册过程。
本发明实施例一中提供了一种本地移动锚点注册的方法流程, 当
LMA 负荷过重、 本地管理策略调整等情况返回失败时, 可以采用两 种方式进行重定向处理: LMA1返回失败时, 带有重定向指示和推荐 的 LMA2地址; MAG向 LMA2发送 PBU进行代理注册; 或 LMA1 返回失败时, 只带有需要重定向的指示, 而未带有推荐的 LMA2地
址(处理 LMA1无应答的情况), MAG根据 MN配置中的 LMA地址 列表, 向其他 LMA发送 PBU进行代理注册。 当 LMA1返回失败时, 指示失败原因为 MN 没有签约该服务或其他认证方面的原因时, 则 MAG不选择其他 LMA。 具体过程如图 2a所示, 包括以下步骤: 步骤 201a, MN附着到网络中,通过 MAG进行接入认证等过程。 步骤 202a, 在接入认证完成时, AAA服务器向 MAG下载 MN 的配置文档, 带有一个或多个 LMA地址, 其中多个 LMA地址可以 具有一定的优先级顺序或无序排列。
步骤 203a, MAG代理 MN进行注册, 向 LMA1发送 PBU请求。 可选地在扩展选项中携带 MN配置中的其他 LMA地址。
步骤 204a, LMA1向 MAG发送 PBA消息, 当 LMA1由于负荷 过重、 本地管理策略等原因无法注册时, 在 PBA消息携带注册失败 信息。 其中, 注册失败信息中携带注册失败原因, 如果注册失败原因 为没有签约该服务或其他认证方面的原因时, 则不进行处理; 如果注 册失败原因为负荷过重、 本地管理策略, 则 PBA消息中携带重定向 指示, 可选地, 该重定向指示中携带 LMA2地址。 其中, LMA1根 据负荷情况、 LMA优先级、 本地配置策略等决定选择需要重定向的 LMA2。 当步骤 203a中接收到的 PBU代理注册消息的扩展项中带有 其他 LMA地址列表 (一个或多个 LMA地址 ) 时, LMA2可以在该 列表中。 另外一种情况, LMA1也可发送消息询问 AAA服务器, 从 AAA服务器中获取 LMA2的地址,在这种情况下, MAG在步骤 202a、 203a中可以不需要获取或携带 MN的 LMA列表,在后面的步骤中也 不需要对 LMA2进行验证。
步骤 205a, 当 MAG收到代理绑定更新失败消息时, 将验证或选 择 LMA2。 如果 PBA消息中带有重定向的 LMA2地址, MAG验证 LMA2地址, 具体包括: 与 MN配置文档的 LMA地址进行比较; 或 通过与 AAA服务器交互, 由 AAA服务器对 LMA2地址进行验证。 如果 PBA消息中没带有 LMA2地址或 LMA1无应答等, 则 MAG从 MN配置中选择 LMA2 (根据优先级顺序选择或轮询), 或从 AAA服
务器中重新获取一个 LMA2地址。
步骤 206a, MAG代理 MN注册, 向 LMA2发送 PBU请求。 步骤 207a, LMA2确认注册成功, 向 MAG发送 PBA消息, 带 有分配给 MN的家乡网络前缀。
步骤 208a, MAG向 MN发送 RA, 通知 MN的家乡网络前缀。 本发明实施例一中还提供了另一种本地移动锚点注册的方法流 程, 作为替代方案, 当 LMA1 由于上述原因不能为 MN提供服务, 在确定 LMA2后, 可以将 PBU消息转发给 LMA2; LMA2直接或者 通过 LMA1向 MAG回复 PBA消息, 完成注册。 如图 2b示, 包括以 下步骤:
步骤 201b, MN附着到网络中, 完成进行接入认证等过程。
步骤 202b, 在接入认证完成时, AAA服务器向 MAG下载 MN 的配置文档。
步骤 203b, MAG代理 MN注册, 向 LMA1发送 PBU注册请求。 步骤 204b, 当 LMA1 由于负荷过重、 本地管理策略等原因不能 为 MN服务; LMA1根据本地配置、 心跳消息等获取 LMA2地址, 可选地, LMA1也可发送消息询问 AAA服务器, 从 AAA服务器中 获取 LMA2的地址。
步骤 205b, LMA1向 LMA2转发 PBU注册请求。
步骤 206b, LMA2向 MAG回复 PBA注册确认消息, 确认注册 成功,带有分配给 MN的家乡网络前缀信息等。其中 PBA经过 LMA1 进行转发, 或直接发送给 MAG。
步骤 207b, MAG向 MN发送 RA, 通知 MN的家乡网络前缀。 本发明实施例二中提供一种本地移动锚点注册的方法流程, 当 MAG获知 LMA的负载情况时,可以基于负载均衡方式进行 LMA选 择, 在代理 MN进行 PBU注册时, 选择 MN配置的 LMA列表中负 荷轻的 LMA进行注册, 具体过程如图 3所示, 包括以下步骤:
步骤 301 , MN附着到网络中, 通过 MAG进行接入认证等过程。 步骤 302,在接入认证完成时, AAA服务器向 MAG下载 MN的
配置文档, 带有一个或多个 LMA地址。
步骤 303 , MAG根据 LMA的负载情况选择负荷轻的 LMA。 步骤 304, MAG代理 MN注册, 向 LMA发送 PBU请求。
步骤 305, LMA确认注册成功, 向 MAG发送 PBA消息, 带有 分配给 MN的家乡网络前缀。
步骤 306, MAG向 MN发送 RA, 通知 MN的家乡网络前缀。 其中, 可以在 MAG上建立一个按降序或者升序排列的 LMA负 荷列表, 根据 MAG与 LMA之间的负荷信息同步进行动态更新。 其 中 MAG和 LMA之间的负荷信息同步流程如图 4, 包括以下步骤: 步骤 401 , LMA向 MAG发送负荷指示消息, 带有 LMA当前的 负荷信息, 其中该负荷信息指示了当前 LMA负荷过重, 或负荷过重 恢复; 或带有具体的负载指标, 例如资源占用情况、 连接占用率等。 负荷指示消息格式如图 5所示, 包括: 类型字段, 例如请求、响应等; L标志字段, 用于指示负载信息, 0表示正常或负荷过重恢复, 1表 示负荷过重; 预留字段; 负荷信息字段, 是一个可选项, 当 LMA向 MAG发送具体的负载指标时使用。
步骤 402, MAG向 LMA回复确认消息,根据 LMA的负荷信息, MAG将动态更新本地的 LMA优先级列表。
上述是 LMA主动向 MAG发送负荷信息的过程, 信息同步也可 以是 MAG主动向 LMA请求负荷情况。 负荷信息同步过程与底层传 输无关, LMA与 MAG之间的可用采用点对点链路传输, 也可以是 LMA向多个 MAG进行组播或广播或任播(anycast )等。 负荷指示、 负荷指示消息, 可以是一个独立的消息, 也可以作为其他消息的一个 选项携带给 MAG, 例如在心跳消息中增加一个负荷选项消息, 如图 6, 其中, 增加 L标志位, 0表示负荷正常或负荷过重恢复, 1表示负 荷过重。 可选地, 可以带有详细的负载情况包含在负荷信息字段中。
本发明实施例三中提供一种本地移动锚点注册的方法流程,为了 缩短 MN接入的延时, MAG从 MN配置中选择一个或多个 LMA; 向各个 LMA同时发送 PBU进行注册, 选择最先响应的 LMA, 将该
LMA分配的家乡网络前缀发送给 MN。 具体过程如图 7所示, 包括 以下步骤:
步骤 701 , MN附着到网络中, 通过 MAG进行接入认证等过程。 步骤 702,在接入认证完成时, AAA服务器向 MAG下载 MN的 配置文档, 带有一个或多个 LMA地址。
步骤 703 , MAG同时向 MN配置中的一个或多个 LMA发起 PBU 注册请求。
步骤 704, —个或多个 LMA确认注册成功, 向 MAG发送 PBA 消息, 带有分配给 MN的家乡网络前缀。
步骤 705, MAG选择最先确认注册成功的, 向 MN发送 RA, 通 知 MN的家乡网络前缀。
步骤 706, MAG向其他的 LMA发起 PBU注销过程。
本发明实施例四中提供一种本地移动锚点注册的方法流程,为了 缩短 MN接入的延时, 同时减少网络信令开销, 当 MAG收到当前 LMA的 PBA注册失败后, MAG向其他 LMA同时发送 PBU进行注 册, 选择最先响应的 LMA, 将该 LMA分配的家乡网络前缀发送给 MN。 具体过程如图 8所示, 包括以下步骤:
步骤 801 , MN附着到网络中, 通过 MAG进行接入认证等过程。 步骤 802,在接入认证完成时, AAA服务器向 MAG下载 MN的 配置文档, 带有一个或多个 LMA地址。
步骤 803, MAG向 LMA1发起 PBU注册。
步骤 804, LMA1由于资源不足、 本地配置策略等原因返回 PBA 失败消息。
步骤 805, MAG向 MN配置中的其他一个或多个 LMA同时发起 PBU注册请求。
