5103、 获取归属业务路由器或业务漫游前所属的业务路由器的地址， 向 所述归属业务路由器或所述业务漫游前所属的业务路由器发送漫游通知消 息， 以便于所述归属业务路由器或所述业务漫游前所属的业务路由器更新业 务漫游路由信息。
本发明实施例中可以将包含所述业务标识和所述业务物理接入地址的 业务注册路由信息， 根据需要存储在业务路由器或业务注册服务器或业务目 录上。
本发明的上述实施例中， 接收业务发送的漫游注册请求消息， 并根据漫 游注册请求消息， 更新业务注册路由信息和业务漫游路由信息， 这样成功的 实现了业务漫游， 用户可以访问该业务， 提高了用户体验和用户自创建业务 的通用性。
本发明实施例的另一种实现业务漫游的方法如图 2所示， 包括：
5201、接收业务漫游后所属的业务路由器发送的漫游通知消息， 所述漫 游通知消息包含业务标识和业务漫游后所属的业务路由器地址；
5202、 根据所述漫游通知消息， 更新所述业务漫游路由信息， 所述更新 后的业务漫游路由信息包含所述业务标识和所述业务漫游后所属的业务路 由器地址。
本发明实施例的另一种实现业务漫游的方法如图 3所示， 包括：
S301、向业务漫游后所属的业务路由器发送包含业务标识的漫游注册请 求消息， 以便于所述业务漫游后所属的业务路由器生成并保存包含所述业务 标识和业务物理接入地址的业务注册路由信息， 归属业务路由器或所述业务 漫游前所属的业务路由器更新业务漫游路由信息。
本发明的上述实施例中， 接收业务发送的漫游注册请求消息， 并根据漫 游注册请求消息， 更新业务注册路由信息和业务漫游路由信息， 这样成功实 现的业务漫游， 用户可以访问该业务， 提高了用户体验和用户自创建业务的 通用性。
本发明实施例一种实现业务漫游的方法如图 4所示， 一种可能的场景： 一个业务部署在移动设备上， 当该业务的网络管理域发生改变， 例如一个虚 拟旅游业务部署在业务创建者的便携计算机上的， 该业务物理接入网络发生 了变化， 此时该业务需要进行漫游注册， 以实现其他用户能够成功访问该业 务。 该方法涉及拜访业务路由器、 拜访业务注册服务器、 归属业务路由器、 归属业务注册服务器、 业务请求者和业务拥有者， 其中拜访业务路由器为该 业务漫游后业务所归属的业务路由器， 拜访业务注册服务器为拜访业务路由 器对应的业务注册服务器， 归属业务路由器为该业务漫游前业务所归属的业 务路由器， 归属业务注册服务器为归属业务路由器对应的业务注册服务器。 具体歩骤如下：
S401、 业务发生漫游时， 向拜访业务路由器发送漫游注册请求消息， 上 述漫游注册请求消息可以携带业务标识、业务漫游状态和业务访问状态等信 息； 该业务标识可以为业务名称， 也可以为业务的逻辑地址； 该业务逻辑地 址可以为该业务的统一资源定位符 （Uniform Resource Locator ， URL); 业 务漫游状态信息包含业务处于漫游状态标识或业务处于非漫游状态标识；业 务访问状态信息包含业务停用状态标识或业务运行状态标识； 漫游注册请求 消息还可以包括归属业务路由器的地址。
在业务发送漫游注册请求消息之前，业务还可以先向归属业务路由器发 送业务访问状态更新消息， 使业务访问状态变成停用状态， 以保证在业务漫 游注册成功之前， 到达归属业务路由器的访问请求能被该归属业务路由器保 存， 等待业务完成漫游后重新处理。
5402、 拜访业务路由器接收漫游注册请求消息后， 根据业务标识， 获取 漫游后的业务物理接入地址， 并在路由表中添加业务注册路由信息， 所述业 务注册路由信息包含业务标识和漫游后的业务物理接入地址， 该业务物理接 入地址可以为漫游后的业务 IP接入地址。
拜访业务路由器还可以获取并保存归属业务路由器的地址， 获取归属业 务路由器的方式有多种：可以根据业务标识向业务目录查询该业务的归属业 务路由器的地址； 也可以从漫游注册请求消息中直接获取， 此时该漫游注册 请求消息包含了该业务的归属业务路由器的地址。
拜访业务路由器在路由表中添加漫游业务注册路由信息之前， 拜访业务 路由器还可以对漫游注册请求消息进行必要的身份鉴权过程； 例如： 拜访业 务路由器向业务拥有者发送认证请求； 根据该认证请求， 业务拥有者向拜访 业务路由器发送业务鉴权指令； 根据该业务鉴权指令， 拜访路由器从业务目 录或者从鉴权中心获取业务认证信息， 根据该业务认证信息， 拜访业务路由 器对该业务进行鉴权。
如果业务鉴权通过， 拜访业务路由器对该业务进行漫游注册； 如果业务 鉴权未通过， 则拜访业务路由器停止为该业务进行漫游注册。
5403、拜访业务路由器添加漫游业务注册路由信息和获取归属业务路由 器地址后， 向拜访业务路由器对应的拜访业务注册服务器发送漫游登记请 求； 该漫游登记请求可以包括： 业务标识、 业务漫游状态、 业务访问状态、 归属业务路由器地址、 拜访业务路由器地址等信息。 5404、 拜访业务注册服务器接收到上述漫游登记请求后， 处理该漫游登 记请求， 保存该漫游业务的业务标识、 业务漫游状态、 业务访问状态和归属 业务路由器地址等信息， 并向拜访业务路由器返回漫游登记响应。
5405、 拜访业务路由器接收到上述漫游登记响应后， 向该业务的归属业 务路由器发送漫游通知消息， 该漫游通知消息可以包含业务标识、 业务漫游 状态和拜访业务路由器地址等信息。
5406、归属业务路由器接收到漫游通知消息后，更新该业务漫游由信息， 删除该业务原路由表项的信息， 并在业务漫游路由信息中添加拜访业务路由 器的地址； 并向归属业务注册服务器发送漫游通知消息， 该漫游通知消息包 含业务标识和业务漫游状态；
5407、 归属业务注册服务器接收到上述漫游通知消息后， 更新业务漫游 状态， 将该业务漫游状态由非漫游状态更改为漫游状态， 保存该业务拜访业 务路由器的地址等信息； 并向归属业务路由器发送漫游通知成功消息。
5408、 归属业务路由器接收上述漫游通知成功消息后， 向拜访业务路由 器发送业务漫游通知成功消息；
5409、 拜访业务路由器接收到漫游通知消息后， 向业务发送漫游注册响 应消息。
如果在该业务漫游注册处理期间， 有访问请求者向归属业务路由器发送 访问请求， 归属业务路由器则缓存该访问请求， 当归属业务路由器接收到归 属业务注册服务器发送的漫游通知成功消息后， 归属业务路由器则将该访问 请求发送到拜访业务路由器。
业务拥有者接收到该漫游注册响应后， 向拜访业务路由器发送业务访问 状态更新消息； 拜访业务路由器接收到业务访问状态更新消息后， 向拜访业 务注册服务器转发业务访问状态更新消息； 拜访业务注册服务器根据业务访 问状态更新消息将该业务的访问状态由停用状态更新为运行状态。
这样该业务漫游注册成功， 其他用户可以实现对该业务进行访问。 如果 此时有访问请求者向该业务拥有者发送访问请求， 则进行以下处理。
5410、 访问请求者向业务拥有者漫游前的归属业务路由器发送访问请 求， 访问请求包含业务请求者的地址、 访问业务的业务标识。
5411、 归属业务路由器接收到上述访问请求后， 向归属业务注册服务器 发送查询请求消息， 上述查询请求消息包含业务标识。
5412、 根据上述业务标识， 归属业务注册服务器获取该业务的业务漫游 状态， 并向归属业务路由器发送查询响应消息， 所述查询响应消息包含该业 务的漫游状态信息。
5413、 归属业务路由器接收归属业务注册服务器返回的查询响应信息 后， 查询该业务所属的拜访业务路由器地址， 并根据拜访业务路由器地址向 拜访业务路由器转发访问请求。
5414、 拜访业务路由器接收到该访问请求后， 向拜访业务注册服务器发 送查询请求消息， 上述查询请求消息可以包含的业务标识。
5415、 根据上述业务标识， 拜访业务注册服务器获取业务访问状态， 并 向拜访业务路由器返回查询响应消息， 上述查询响应消息包含业务的访问状 态信息。
5416、 拜访业务路由器接收到上述查询响应消息后， 如果该业务访问状 态为运行状态， 则获取该业务漫游后的物理接入地址， 如从拜访业务路由器 的路由表中查询该业务物理接入地址； 根据业务物理接入地址， 向业务转发 上述访问请求。
如果该业务访问状态为停用状态， 则向归属业务路由器发送访问失败响 应， 以便于归属业务路由器向业务请求者返回访问失败响应。
5417、 业务拥有者接收该访问请求后， 处理业务请求， 并向拜访业务路 由器发送访问响应。
S418、 拜访业务路由器转发该访问响应至业务请求者。
本发明实施例中， 当业务的网络管理域发生改变时， 也就是说业务发生 漫游时， 业务拥有者会向其拜访业务路由器发送漫游注册请求消息， 拜访业 务路由器和拜访业务注册服务器为该业务进行注册登记处理， 并通知归属业 务路由器该业务已经漫游， 归属业务路由器更新该业务漫游路由信息， 并且 归属业务注册服务器更新业务漫游状态， 这样成功实现的业务漫游， 用户可 以进行访问该业务， 提高了用户体验和自创建业务的通用性。
本发明另一种实现业务漫游的方法中， 业务标识、 业务访问状态、 业务 注册路由信息和归属业务路由器地址都保存在拜访业务注册服务器中，而拜 访业务路由器只是负责消息的中转， 详细过程同图 4对应的实施例类似。
本发明另一种实现业务漫游的方法如图 5所示， 图 4对应的实施例不同 的是： 业务路由器集成了业务注册服务器的功能， 单独由业务路由器处理业 务注册的过程， 具体包括歩骤：
S501同 S401 , 这里不做详细叙述。
S502、 拜访业务路由器接收漫游注册请求消息后， 拜访业务路由器保存 相关信息， 包括： 业务标识、 业务漫游状态和业务访问状态， 并根据业务标 识， 获取漫游后的业务物理接入地址， 并在路由表中添加漫游业务注册路由 信息， 所述业务注册路由信息包含业务标识和漫游后的业务物理接入地址， 该业务物理接入地址可以为漫游后的业务 IP接入地址。
拜访业务路由器还可以获取并保存归属业务路由器的地址， 获取归属业 务路由器的地址方式有多种： 可以根据业务标识向业务目录查询该业务的归 属业务路由器的地址； 也可以从漫游注册请求消息中直接获取， 此时该漫游 注册请求消息包含了该业务的归属业务路由器的地址。
拜访业务路由器在路由表中添加漫游业务注册路由信息之前， 拜访业务 路由器还可以对漫游注册请求消息进行必要的身份鉴权过程； 例如： 拜访业 务路由器向业务拥有者发送认证请求； 根据该认证请求， 业务拥有者向拜访 业务路由器发送业务鉴权指令； 根据该业务鉴权指令， 拜访路由器从业务目 录或者从鉴权中心获取业务认证信息， 根据该业务认证信息， 拜访业务路由 器对该业务进行鉴权。
如果业务鉴权通过， 拜访业务路由器对该业务进行漫游注册； 如果业务 鉴权未通过， 则拜访业务路由器停止为该业务进行漫游注册。
5503、拜访业务路由器添加漫游业务注册路由信息和获取归属业务路由 器地址后， 向该业务的归属业务路由器发送漫游通知消息， 该漫游通知消息 可以包含业务标识、 业务漫游状态和拜访业务路由器地址等信息。
5504、归属业务路由器接收到漫游通知消息后，进行漫游通知消息处理， 包括： 更新该业务漫游路由信息， 删除该业务原路由表项的信息， 并在路由 信息中添加拜访业务路由器的地址； 并保存业务标识、业务漫游状态和拜访 业务路由器地址等信息； 并向拜访业务路由器发送漫游通知成功消息。
5505、 拜访业务路由器接收到漫游通知消息后， 向业务发送漫游注册响 应。
如果在该业务漫游注册处理期间， 有访问请求者向归属业务路由器发送 访问请求， 归属业务路由器则缓存该访问请求， 当归属业务路由器向拜访业 务路由器发送漫游通知成功消息时， 归属业务路由器则同时将该访问请求发 送到拜访业务路由器。
业务接收到该漫游注册响应后， 向拜访业务路由器发送业务访问状态更 新消息； 拜访业务路由器将该业务的访问状态由停用状态更新为运行状态。
这样该业务漫游注册成功， 其他用户可以实现对该业务进行访问。 如果 此时有访问请求者向该业务发送访问请求， 则进行以下处理。
5506、访问请求者向业务发送访问请求， 访问请求包含业务请求者的地 址、 访问业务的业务标识； 该访问请求首先被发送给归属业务路由器。
5507、归属业务路由器接收到上述访问请求后，查询该业务的漫游状态， 获知该业务已经漫游， 则查询获取该业务的拜访业务路由器的地址， 并根据 拜访业务路由器地址向拜访业务路由器发送转发访问请求。
5508、 拜访业务路由器接收到该访问请求后， 根据业务标识， 查询该业 务的访问状态； 如果该业务访问状态为运行状态， 则获取该业务漫游后的物 理接入地址； 并根据业务物理接入地址， 向业务转发上述访问请求。
如果该业务访问状态为停用状态， 则向归属业务路由器发送访问失败响 应， 以便于归属业务路由器向业务请求者返回访问失败响应。
S509、 业务接收该访问请求后， 处理业务请求， 并向拜访业务路由器发 送访问响应。
S510、 拜访业务路由器转发该访问响应至业务请求者。
本发明实施例中， 当业务的网络管理域发生改变时， 也就是说业务发生 漫游了， 业务会向其拜访业务路由器发送漫游注册请求消息， 拜访业务路由 器为该业务进行注册登记处理， 并通知归属业务路由器该业务已经漫游， 归 属业务路由器更新该业务漫游路由信息和更新业务漫游状态， 这样成功实现 的业务漫游， 用户可以进行访问该业务， 提高了用户体验和用户自创建业务 的通用性。
本发明实施例另一种实现业务漫游的方法如图 6所示， 与图 4对应的实 施例的区别是： 拜访业务注册服务器和归属业务注册服务器的功能集成到业 务目录中。 假设漫游前， 业务归属于业务路由器 B， 发生漫游后， 该业务归 属于业务路由器 A， 在这种情况下， 业务请求者发送访问请求至其归属业务 路由器后， 该业务路由器会首先查询业务目录获取该业务的归属业务路由 器， 然后转发访问请求至该业务的归属业务路由器。 具体歩骤如下：
S601、业务发生漫游时， 向业务路由器 A发送漫游注册请求消息， 所述 漫游注册请求消息可以携带业务标识、 业务漫游状态和业务访问状态等信 息， 该该业务标识可以为业务名称或业务代码， 也可以为业务的逻辑地址， 该业务逻辑地址可以为该业务的 URL;漫游注册请求消息还可以包括漫游前 业务所属的业务路由器的地址； 业务漫游状态信息包含业务处于漫游状态标 识或业务处于非漫游状态标识； 业务访问状态信息包含业务停用状态标识或 业务运行状态标识； 漫游注册请求消息还可以包括归属业务路由器的地址； 在业务发送漫游注册请求消息之前，业务还可以先向业务路由器 B发送 业务访问状态更新消息， 使业务访问状态变成停用状态， 以保证在业务漫游 注册成功之前， 到达业务路由器 B的访问请求能被业务路由器 B保存下来， 等待业务完成漫游后重新处理。
S602、业务路由器 A接收到该漫游注册请求消息后， 根据业务标识， 获 取漫游后的业务物理接入地址， 并在路由表中添加漫游业务注册路由信息， 所述业务注册路由信息包含业务标识和漫游后的业务物理接入地址， 该业务 物理接入地址可以为漫游后的业务 IP接入地址。
业务路由器在路由表中添加漫游业务注册路由信息之前， 业务路由器 A 可以对漫游注册请求消息进行必要的身份鉴权过程，例如：业务路由器 A向 业务发送认证请求； 根据该认证请求，业务向业务路由器 A发送业务鉴权指 令； 根据该业务鉴权指令，业务路由器 A从业务目录或者从鉴权中心获取业 务认证信息， 根据该业务认证信息， 业务路由器 A对该业务进行鉴权。如果 业务鉴权通过，业务路由器 A为该业务进行漫游注册；如果业务鉴权未通过， 则业务路由器 A拒绝为该业务进行漫游注册。
5603、业务路由器 A完成对业务进行漫游注册后，获取并保存业务路由 器 B的地址， 获取该业务路由器 B的方式有多种： 可以根据业务标识向业 务目录查询所述业务的漫游前所属业务路由器 B的地址；也可以从漫游注册 请求消息中直接获取，此时该漫游注册请求消息包含了该业务的漫游前所属 业务路由器 B的地址。并向业务目录发送漫游登记请求， 该漫游登记请求可 以包括： 业务标识、 业务漫游状态、 业务访问状态、 业务路由器 B地址、 业 务路由器 A地址等信息。
5604、业务目录接收到上述漫游登记请求后， 保存更新该业务登记保存 和该业务的用户访问信息， 登记保存可以包括业务标识、 业务漫游状态、 业 务访问状态、 当前所属的业务路由器 A的地址等信息。 并向业务路由器 A 返回漫游登记响应，用户访问信息包含业务标识和业务当前所属业务路由器 地址。
5605、业务路由器 A接收业务目录返回的漫游登记请求响应后，并根据 业务路由器 B的地址， 向业务路由器 B发送漫游通知消息， 其中该漫游通 知消息包含业务标识、 业务路由器 A的地址和业务漫游状态等信息。
5606、业务路由器 B接收到上述漫游通知消息后，更新该业务漫游路由 信息， 删除该业务原路由表项的信息， 并在业务漫游路由信息中缓存业务路 由器 A的地址，这样使后续的访问请求消息直接转发至业务路由器 A; 并向 业务路由器 A发送漫游通知成功消息。
如果业务请求者在进行业务访问过程中， 业务发生了漫游， 业务请求者 可能没有获得业务目录更新后的访问信息。 因此， 一部分访问请求仍然会发 送至业务路由器 B,该业务路由器 B仍然要维护该业务漫游路由信息一段时 间， 并将接收到的访问请求转发至业务路由器 A。 在设定的时间后删除业务 路由器 A的地址， 以减少对业务路由器 B的负载。 如果是这种情况， 则执 行 S607至 S611。
5607、业务路由器 B接收访问请求者发送的访问请求，访问请求包含业 务请求者的地址、 访问业务的业务标识。
5608、 业务路由器 B根据上述业务标识， 获取业务路由器 A的地址， 并向业务路由器 A转发上述访问请求。
5609、业务路由器 A接收到上述访问请求， 根据上述业务标识， 业务路 由器 A从业务目录获取该业务的漫游状态信息、访问状态信息等信息； 并根 据上述漫游状态信息、 访问状态信息和业务的物理接入地址， 向该业务发送 访问请求。
5610、 业务接收上述访问请求后， 处理该访问请求， 并向业务路由器 A 返回访问响应。
5611、 拜访路由器接收到访问响应后， 向访问请求者发送访问响应。 本发明实施例中， 当业务的网络管理域发生改变时， 也就是说业务发生 漫游了， 业务会向其当前归属的业务路由器发送漫游注册请求消息， 当前归 属的业务路由器和业务目录为该业务进行注册登记处理， 并通知漫游后归属 的业务路由器该业务已经漫游， 漫游后归属的业务路由器更新该业务漫游路 由信息， 这样就实现了业务漫游注册过程， 保证其他用户访问该业务， 提高 了用户的体验； 并且本实施例中将业务注册服务器的功能集成到业务目录 中， 使得业务目录集中控制业务的交换、 业务漫游注册、 路由查询等， 这有 利于运营商控制业务的运营。
本发明实施例的一种业务路由器如图 7所示， 包括：
漫游注册请求消息接收单元 701， 用于接收包含业务标识的漫游注册请 求消息；
业务注册路由信息生成单元 702， 用于根据所述业务标识， 获取业务物 理接入地址， 生成并保存包含所述业务标识和所述业务物理接入地址的业务 注册路由信息；
