Description

触发路由优化的方法、 装置及代理移动 IP系统 技术领域
本发明涉及移动通信技术领域, 特别涉及触发路由优化的方法、 装置及 代理移动 IP系统。
背景技术
代理移动 IP (Proxy Mobile IP, PMIP )是一种网络侧移动管理协议, 无 需移动节点 (Mobile Node, MN )参与移动性管理, 就可实现 IP会话连续性。 不管主机是否支持移动 IP (Mobile ΙΡ,ΜΙΡ), 都可以通过 PMIP实现移动性管 理, 并可以减少信令开销和空口资源。
PMIP的系统架构如图 1所示。在 PMIP系统中,引入移动接入网关(Mobile Access Gateway, MAG )这个新的功能实体。 MAG是代表 MN执行移动性相关的 信令的实体。 当 MN接入 MAG链路上后, 作为接入认证过程的一部分, MN将以 网络接入标识符 ( Network Access Identifier, NAI ) 的形式通知其身份至 网络。 成功认证后, MAG从策略存储实体(如接入 4受权认证(Authentication Authorization Account, AAA ) 中获取 MN的家乡前缀( prof i le )。 MAG开始周 期性发送路由器通告(Router Advertisement, RA ), 通告所述 MN 的家乡前 缀, 在接入链路上模仿 MN的家乡网络。
MN收到 RA后,基于链路上允许的配置方式, 将使用有状态或者无状态配 置接口地址, 从而获得 MN家乡地址。
MAG发送一个代理绑定更新 (Proxy Binding Update, PBU ) 消息至 MN的 本地移动锚点 (Local Mobility Anchor, LMA ); LMA收到 PBU后, 建立 LMA 至 MAG的隧道。 LMA通过隧道, 创建至 MN家乡网络前缀的路由, 发送代理绑 定通知 ( Proxy Binding Acknowledgement, PBA )至 MAG。 MAG收到 PBA后将 创建至 LMA的隧道。 之后所有来自于 MN的业务, 将经过此隧道转发至 LMA。
以上所述 PMIP的通信过程, MN之间的通信报文都要经过 LMA, —定程度 上导致了路由复杂, 因此需要应用路由优化(Route Opt imiza t ion, RO ) 过 程来简化路由。
根据 MN以及对端通信节点 (Correspond Node , CN ) 的拓朴关系的不同, 可以分为如下四种情况:
情况 1: MN、 CN属于相同的 MAG和 LMA;
情况 2: MN、 CN属于相同的 MAG, 但属于不同的 LMA;
情况 3: MN、 CN属于不同的 MAG, 但属于相同的 LMA;
情况 4: MN、 CN属于不同的 MAG, 但属于不同的 LMA。
其中, 情况 1和情况 2不需要 MAG间任何的信令, 分组就可以进行路由。 由于 MN和 CN都属于相同的 MAG, MAG将代表它们执行注册过程和维护绑定緩 存列表。 当 MAG收到来自于 CN的报文, MAG应该查询绑定更新列表以确认报 文目的地址是否作为家乡地址出现在其中, 如果是, 意味着 MAG 已经代表该 报文的目的节点注册至 LMA, MAG应该直接转发报文至 MN, 而不是再通过双向 隧道转发报文至 LMA, 从而实现路由优化。
情况 3和情况 4中, 理想的路径是在两个 MAG之间建立双向隧道用于路 由优化。 MN的 MAG1需要知道 CN的 MAG2的 IP地址, 用于初始化路由优化信 令过程。
但是,现有方案中触发路由优化的方案不够灵活,要么不能为 MN实现 R0, 要么为 MN的所有数据流进行 R0,无法实现对不同的业务实施不同的 R0策略, 不能满足实际业务的需要。
发明内容
本发明实施例提供一种触发路由优化的方法、 装置及代理移动 IP系统, 能够更为灵活地实施路由优化策略。
一种触发路由优化的方法, 包括:
移动接入网关 MAG获得路由优化策略或路由优化策略触发消息, 其中, 路由优化策略和路由优化策略触发消息用于对移动节点 MN的路由进行优化; 移动接入网关 MAG根据路由优化策略或路由优化策略的触发消息 , 对 MN 的路由进行路由优化。
一种移动接入网关, 包括:
路由优化策略接收模块, 用于接收路由优化策略, 并将所接收的路由优 化策略发送至路由优化模块;
路由优化模块, 用于根据路由优化策略, 对用于转发 MN数据的路由进行 优化。
一种触发路由优化的代理移动 IP系统, 包括 MAG , 还包括策略服务器, 用于存储路由优化策略, 并能够发送存储的路由优化策略;
所述 MAG 包括: 路由优化策略接收模块, 用于接收路由优化策略, 并将 路由优化策略发送至路由优化模块;
路由优化模块, 用于接收所述路由优化策略接收模块发送的路由优化策 略, 根据路由优化策略, 对 MN的路由进行路由优化。
一种触发路由优化的移动节点, 包括:
路由优化策略设定模块, 用于设定路由优化策略信息;
路由优化策略发送模块, 用于向网络侧发送路由优化策略设定模块所设 定的路由优化策略信息。
从以上技术方案可以看出, 在网络侧设置策略服务器来存储和收集路由 优化策略, 并将该路由优化策略下发至 MAG , 则 MAG可以根据所收到的路由优 化策略执行相应的路由优化操作, 从而可以实现根据 MN业务的实际需要进行 路由优化, 更为灵活地实施路由优化策略。
附图说明
图 1为现有技术中 PMIP系统架构示意图;
图 2为本发明实施例实现路由优化的系统示意图;
图 3为本发明第一实施例触发路由优化的流程图;
图 4为本发明第二实施例触发路由优化的流程图; 图 5为本发明第三实施例触发路由优化的流程图。
具体实施方式
MIP中的路由优化是端到端的操作。 但在 PMIP中, MAG和 LMA只是中间 路由器, 不能判断报文是否需要路由优化, 因此只能固定地对所有报文进行 路由优化或者不进行路由优化。 本发明实施例提供一种机制, 允许 MN直接或 间接通知 MAG或者 LMA对路由进行优化, 其中, 路由优化可以是与特定 CN通 信进行路由优化, 或让 MAG或者 LMA对 MN与每一个与之通信的 CN间的路由 进行优化。
在 PMIP系统中,本发明的实施例提供了一种路由优化的方法,是通过 MAG 或者 LMA获得路由优化策略, 触发 MAG来进行, 下面列举了三种具体实现过 程:
1 ) AAA在接收到 MAG或者 LMA的认证请求之后, 向策略服务器请求获得 MN的路由优化策略, 并将获得的路由优化策略发送给 MAG或者 LMA。 当路由 优化策略发送给 MAG时, 由 MAG根据路由优化策略进行路由优化; 当路由优 化策略发送给 LMA时, LMA将路由优化策略转发至 MAG, 并由 MAG进行路由优 化。
2 ) AAA在接收到 MAG或者 LMA的认证请求之后, 请求策略服务器发送 MN 的路由优化策略给 MAG或 LMA, 策略服务器根据 MAG或 LMA的地址,发送路由 优化策略至 MAG或 LMA。 当路由优化策略发送给 MAG时, 由 MAG根据路由优化 策略进行路由优化; 当路由优化策略发送给 LMA时, LMA将路由优化策略转发 至 MAG , 并由 MAG进行路由优化。
3 ) MN在登录网络后, 通过应用层控制协议在策略服务器上配置路由优化 策略, 并触发策略服务器发送 MN的路由优化策略至 MAG或者 LMA。 当路由优 化策略发送给 MAG时, 由 MAG根据路由优化策略进行路由优化; 当路由优化 策略发送给 LMA时, LMA将路由优化策略转发至 MAG,并由 MAG进行路由优化。 但与上面 1 )、 2 )提供的方法不同之处在于, 1 )、 2 )方法中获得的路由优化 策略是静态配置路由优化策略; 而通过应用层控制协议触发获得的路由优化 策略可能是静态配置路由优化策略, 可能是动态路由优化策略, 也可能是静 态配置路由优化策略和动态路由优化策略。
此外, 除了上述的 MAG获得路由优化策略后进行路由优化方案之外, 还 可以在上述步骤中, 当路由优化策略发送到 LMA时, LMA还可以根据路由优化 策略决定是否发送路由优化策略触发消息触发 MAG进行路由优化, 而不是把 路由优化策略发送给 MAG, 这里路由优化策略触发消息里面包含 MAG对 MN的 路由进行优化所需的相关信息, 例如, MN的端口、 数据源地址、 数据目的地 址或数据所釆用的协议。 此时, LMA可以不将路由优化策略转发给 MAG, 仍然 可以完成路由优化的触发。
为便于表述, 以下将与 MN直接相连的 MAG称为 MN-MAG, 将与 CN直接相 连的 MAG称为 CN-MAG。
本发明实施例的实现路由优化的系统如图 2 所示, 其中虚线表示未进行 路由优化的数据流, 粗实线表示路由优化后的数据流。
当为上述 1 )方法时,
AAA用于接收到 MAG或 LMA的认证请求后, 从策略服务器获得 MN的路由 优化策略, 并将所述路由优化策略发送给 MAG或者 LMA;
策略服务器用于存储和响应 MN静态配置路由优化策略或动态路由优化策 略;
LMA用于当 AAA将获得的路由优化策略发送给 LMA时,把所述路由优化策 略发送给 MAG。
当为上述 2 )方法时,
AAA用于接收到 MAG的认证请求后, 请求策略服务器发送顯的路由优化 策略给 MAG或 LMA;
策略服务器用于根据 MAG或 LMA的地址,发送路由优化策略至 MAG或 LMA; LMA用于当策略服务器将路由优化策略发送给 LMA时,把所述路由优化策 略发送给 MAG。
当为上述 3 )方法时,
MN用于请求策略服务器发送 MN的路由优化策略至 MAG或 LMA;
策略服务器用于根据 MAG或 LMA的地址,发送路由优化策略至 MAG或 LMA; LMA用于当策略服务器将路由优化策略发送给 LMA时,把所述路由优化策 略发送给 MAG。
策略服务器作为一个逻辑功能实体, 并不限定其具体的承载实体。 所述 策略服务器中存储了 MN的路由优化策略信息以及用于标识路由优化策略信息 的 R0标识(RO Flag X 例如:
RO Flag=0, 所对应的路由优化策略为对 MN 的所有数据流不进行任何形 式的路由优化;
RO Flag=l , 所对应的路由优化策略为对 MN的所有数据流进行路由优化; RO Flag=2 , 所对应的路由优化策略为对 MN的特定数据流进行路由优化。 若 RO Flag=0或 1 , 下发的路由优化策略可以仅包括 RO Flag; RO Flag=2 时, 下发的路由优化策略可以包括 RO Flag 以及数据流的特征信息。 所述特 征信息包括但不限于 MN的端口、 数据流源地址、 数据流目的地址、 数据流所 釆用的协议等。 当应用 RO Flag=2 所对应的路由优化策略时, 策略服务器将 该路由优化策略下发到 MN-MAG后, MN-MAG检查 MN的业务数据流的特征信息 是否符合路由优化策略中的数据流特征信息, 若是, 则触发对该数据流执行 路由优化。
MN还可以通过 MAG或 LMA、 AAA的转接, 连接策略服务器, 对策略服务器 中的路由优化策略进行创建、 删除或修改。 所述修改可以是修改 RO Flag 的 数值和 /或路由优化策略中的数据流特征信息。
上述 Flag类型值仅用于说明本发明实施例具体的处理过程, 实际应用中 并不局限于此种形式。
结合图 2进一步说明本发明实施例系统的路由优化过程具体包括: MN-MAG 向 CN-MAG 注册 MN 的家乡地址和 MN-MAG 的代理转交地址 ( Proxy-CoA ) 的绑定关系; CN发给 MN的数据报文在 CN-MAG处直接转发给 MN-MAG;
CN-MAG同时也向 MN-MAG注册 CN的家乡地址和 CN-MAG的 Proxy-CoA的绑 定关系; MN发给 CN的数据报文在 MN-MAG处直接转发给 CN-MAG。
在本发明实施例中, 根据路由优化标志位设置不同, MAG或对所有数据流 进行路由优化, 或需要 MN通知其决定如何进行路由优化。
为使本发明的目的、 技术方案和优点更加清楚, 以下通过实施例对本发 明方案进行详细阐述。
在 PMIP系统中, 当 MN接入网络后, 网络需要对 MN进行认证, 该认证过 程由 MAG代替顯来进行。图 3所示为本发明第一实施例触发路由优化的流程, 结合图 2的系统图对步骤进行说明:
步骤 301 : MN-MAG代表 MN向 AAA发送认证请求 (其中包含 MN的 NAI ); 步骤 302 : AAA向策略服务器请求关于 MN的预置路由优化策略; 所述预 置路由优化策略中包含 R0标识, 或者 R0标识和数据流特征信息;
步骤 303: 策略服务器向 AAA返回包含 MN的预置路由优化策略的认证应 答;
步骤 304 : AAA收到来自于策略服务器的所述预置路由优化策略后, 返回 包含所述预置路由优化策略的认证响应至 MN-MAG; 当所述预置路由优化策略 下发至 LMA时, LMA再转发所述预置路由优化策略至 MAG , 触发 MAG进行路由 优化。
从以上步骤可以看出, 在网络对 MN的认证过程中, 将网络侧的策略服务 器中预先存储的路由优化策略发送至 MN-MAG。 在随后的业务过程中, MAG根 据所述路由优化策略执行相应的路由优化操作:
若 R0 F lag=0 , 则 MAG不进行任何路由优化;
若 R0 F lag=l , 则 MAG对 MN的所有数据流进行路由优化; 若 RO Flag = 2 , 则 MAG分析 MN发出的数据流的特征信息, 判断所述特征 信息是否符合路由优化策略中的数据流特征信息, 若是, 则对所述数据流进 行路由优化, 对不符合的数据流则不进行路由优化。
本发明第二实施例触发路由优化的流程如图 4所示, 结合图 2对步骤进 行说明:
步骤 401 : MN-MAG或 MN-LMA代表 MN向 AAA发送认证请求 (其中包含顯 的 NAI );
步骤 402: AAA向策略服务器请求关于 MN的预置路由优化策略; 所述 AAA 在向策略服务器发送 MN的预置路由优化策略的请求消息中,包含了 MAG或 LMA 的地址;
步骤 403: AAA返回常规的关于 MN的认证响应至 MAG或 LMA;
步骤 404 : 策略服务器根据 MAG或 LMA的地址, 直接向 MAG或 LMA返回 MN的预置路由优化策略。 当所述 MN的预置路由优化策略下发至 LMA时, 由 LMA再转发所述 MN的预置路由优化策略至 MAG , 触发 MAG进行路由优化。
上述两个实施例都是 MN上线注册时, 通过认证过程触发路由优化策略的 下发, 本发明第三实施例触发路由优化的流程是在 MN在线的过程中, MN触发 路由优化策略下发, 具体如图 5所示, 包括如下步骤:
步骤 501 : MN启用应用服务器程序, 通过应用层协议(例如超文本传输 协议 HTTP ) 向策略服务器传输路由优化策略的动态变化信息。 所述动态变化 信息可以是对路由优化策略的增加、 删除或修改。
步骤 502: 策略服务器将 MN的路由优化策略发送至 MAG, 触发 MAG进行 路由优化, 或将所述 MN的路由优化策略发送至 LMA, 由 LMA再转发所述 MN的 路由优化策略至 MAG, 触发 MAG进行路由优化。 其中, 所述路由优化策略可以 是静态配置路由优化策略或动态路由优化策略或静态配置路由优化策略和动 态路由优化策略。
以上实施例中所述 AAA与策略服务器之间的请求响应消息, 或者策略服 务器与 MAG或 LMA之间的消息可以釆用专门定义的请求响应消息, 或者通过 修改原有的相关信息, 如 AAA的属性值对(AVP )属性值来实现。
