Description

多宿主场景下进行路由的方法及装置 技术领域
本发明涉及互联网通信领域，尤其涉及一种多宿主场景下进行路由的方法及装置。
背景技术
随着互联网技术的不断发展，下一代互联网对网络的连通性和访问的可靠性具有更高的要求，多宿主技术应运而生。多宿主技术是指一个终端可以具有多个网络提供者，这多个提供者会为终端分配多个IP(Internet Protocol，因特网协议)地址，终端可以使用这多个IP地址的任一个进行路由，使得终端可以通过多条不同的路径接入网络。
目前，终端选择源IP地址进行路由的方式如下：对于一个终端来说，在建立PDU(Packet Data Unit，数据包单元)连接后，该终端可以被分配到至少两个IP地址，IP1和IP2，其中，IP1由本地用户面网关1分配，IP2由远端用户面网关分配。进而，终端可以通过动态主机设置协议、路由发现协议或者源地址选择规则使得IP1与本地应用服务器1上的IP4和IP5绑定，即终端使用IP1与本地应用服务器1通信；通过上述绑定，使得终端在与本地应用服务器1进行通信时，可以根据目的IP地址(IP4或IP5)选择已绑定的IP1作为源IP地址进行路由。
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
UE通过DHCP、RA或者源地址选择规则(RFC6724)使得IP1与IP4和IP5绑定，即UE使用IP1与Local AS1上的IP4和IP5通信，IP4和IP5不在一个地址段时，IP1就要分别和IP4和IP5绑定一次，Local AS1上部署多个APP，IP1就要和这多个APP对应的地址分别进行绑定，造成信令冗余。

WiFi属于短距离无线传输技术，终端200通过WiFi模块170可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图2示出了WiFi模块170，但是可以理解的是，其并不属于终 端200的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器180是终端200的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器120内的软件程序和/或模块，以及调用存储在存储器120内的数据，执行终端200的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器180可包括一个或多个处理核心；优选的，处理器180可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器180中。

图4是本发明实施例提供的一种多宿主场景下进行路由的方法的流程示意图。参见图4，包括：
401、服务器(server)根据至少一个管理平台上部署的应用(APP)，生成该至少一个管理平台的APP列表。
管理平台是用来部署APP及管理该APP对应的应用服务器的平台，例如，该管理平台可以是MEC(Mobile Edge Computing，移动边缘计算)平台，该MEC平台上可以部署多个APP。
在本发明实施例中，管理平台具有地理性，也即是，一个管理平台仅用于管理某一个地域范围内的应用服务器，为了便于区分，将管理平台与IP地址段或位置区相关联，使得每个管理平台对应于一个IP地址段或一个位置区。
Server通过与至少一个管理平台交互，检测该至少一个管理平台上部署的APP，根据该至少一个管理平台上部署的APP，生成该至少一个管理平台的APP列表，并将该至少一个APP列表存储在本地。
402、UE通过建立PDU连接，得到IP1和IP2，IP1和IP2的IP类型分别为IP type1和IP type2。
在本发明实施例中，用IP1来指代第一IP地址，用IP type1来指代第一IP类型。UE可以发起经由本地用户面网关1(Local UP-GW1)和远端用户面网关(UP-GW)的PDU连接，在该PDU连接建立后，被分配到两个IP地址IP1和IP2，该IP1和IP2可以由控制面网元(CP)分配，UE可以使用IP1或IP2进行路由。
403、UE向server发送UE的位置信息1和IP type1或者IP 1。
在本发明实施例中，用位置信息1来指代第一位置信息。建立PDU连接得到IP1后，UE可以将UE的位置信息1和IP type1或者IP 1通知server，即UE可以将UE的位置信息1和IP type1通知server；也可以将UE的位置信息1和IP 1通知server，由server识别该IP 1的IP类型为IP type1。
其中，该位置信息1和IP type1或者IP 1可以由网络类型请求消息携带，例如，UE可以向server发送网络类型请求消息，该网络类型请求消息携带位置信息1和IP type1或者IP 1。该网络类型请求消息除了携带UE的位置信息1和IP type1或者IP 1外，还可以携带数据网络名称(DN name)，从而告知服务器UE要访问的DN。
上述描述是以UE采用网络类型请求消息的形式向server发送UE的位置信息1和IP type1或者IP 1为例进行说明。实际上，UE还可以采用其他消息向server发送UE的位置信息1和IP type1或者IP 1，本发明实施例对此处的发送时机和发送形式不做限定。
本发明实施例是以UE向server发送位置信息1和IP type1或者IP 1为例进行说明，实际上，位置信息1和IP type1或者IP 1还可以由CP在UE发起的PDU连接建立后发送给server。即由CP将该位置信息1和IP type1或者IP1发送给server。
404、server接收UE的位置信息1和IP type1或者IP 1，并将IP type1对应的IP地址段1或者IP type1对应的位置区1绑定的APP列表1发送给UE，该位置区1由该位置信息1确定。
在本发明实施例中，用APP列表1来指代第一应用列表，用位置区1来指代第一位置区，用IP地址段1来指代第一IP地址段。当server接收到UE的位置信息1和IP type1或者IP 1时，可以根据该IP 1确定IP地址段1，根据 该位置信息1确定位置区1。
根据该IP地址段1或者位置区1，server可以从本地存储的至少一个APP列表中，获取APP列表1，该APP列表1是server根据该IP地址段1或者位置区1对应的管理平台上的APP生成的APP列表1，并将该IP type1对应的IP地址段1或者该IP type1对应的位置区1与该APP列表1绑定，并将该APP列表1发送给UE。
对应步骤403中的举例，该APP列表1可以由网络类型应答消息携带。例如，server在接收到UE的网络类型请求消息后，作为对该请求消息的应答，可以向UE返回网络类型应答消息，该网络类型应答消息携带该APP列表1。该网络类型应答消息除了携带APP列表1外，还可以携带IP地址段1或者IP type1。
需要说明的是，server还可以不以网络类型应答消息的方式向UE发送APP列表1，例如，server可以采用其他消息向UE发送该APP列表1，本发明实施例对此处的发送形式不做限定。
本发明实施例是以server向UE发送APP列表1为例进行说明，实际上，server还可以将APP列表1发送给CP，并由CP将该APP列表1发送给UE。
405、UE接收server返回的APP列表1，当UE针对该APP列表1中的APP发起业务时，根据该业务对应的APP选择IP地址段1内的IP或者IP type1的IP地址作为源IP地址。
当UE通过任一APP发起业务时，根据该APP查询本地已存储的至少一个APP列表，如果该APP位于本地已存储的某一个APP列表中时，确定该APP列表，并获取该APP列表所绑定的IP地址段或者IP类型，并从已有的IP地址，如IP1和IP2中，选择该IP地址段内的IP或者该IP类型的IP地址作为源IP地址，在后续业务过程中，可以选择该IP地址进行路由。
在本发明实施例中，该业务可以为某种请求，例如，建立连接请求、通信请求、数据传输请求等。
例如，在本发明实施例中，当UE通过APP1发起通信请求时，根据该APP1查询本地已存储的至少一个APP列表，如果该APP1位于本地已存储的APP列表1中时，确定该APP列表1，并获取该APP列表1所绑定的IP地址段1或者IP type1，从已有的IP地址，IP1和IP2中选择该IP地址段1内的IP1或者该IP type1的IP1，在后续业务过程中，可以使用该IP1进行路由，与APP1 对应的服务器进行通信。
406、UE发生移动后，建立经由本地用户面网关2(Local UP-GW2)的PDU连接，得到IP3，IP3的IP类型为IP type3。
在本发明实施例中，用IP3来指代第二IP地址，用IP type3来指代第二IP类型。由于IP3和IP1都是建立经由本地用户面网关的PDU连接得到的IP地址，因此IP3的IP类型和IP1的IP类型相同，即IP type1和IP type3均为Local类型。当发生移动后，UE对应的本地用户面网关可能会发生改变，则UE会被分配新的IP地址。例如，当UE从Local UP-GW1切换至Local UP-GW2后，被分配IP3，该IP3可以由CP分配，UE可以使用IP3进行路由。
407、UE将移动后UE的位置信息2和IP type3或者IP3发送给server。
本发明实施例中，用位置信息2来指代第二位置信息。UE发生移动，建立PDU连接得到IP3后，可以将UE的位置信息2和IP type3或者IP3发送给server，即UE可以将UE的位置信息2和IP type3通知server；也可以将UE的位置信息2和IP 3通知server，由server识别该IP 3的IP类型为IP type3。
本发明实施例是以UE只要发生移动得到新IP地址IP3就将位置信息2和IP type3或者IP3发送给server为例进行说明。在本发明的另一实施例中，UE发生移动得到新IP地址IP3后，可以根据该IP3或位置信息2判断是否需要将位置信息2和IP type3或者IP3发送给server。只有当UE发生移动后新分配的IP地址IP3不在IP地址段1内或者UE移出位置区1才将位置信息2和IP type3或者IP3发动给server。
另外，本发明实施例是以UE向server发送位置信息2和IP type3或者IP3为例进行说明，实际上，位置信息2和IP type3或者IP3还可以由CP在UE发起的PDU连接建立后发送给server。在一种可能实现方式中，UE只要发生移动得到新IP地址IP3，CP就将位置信息2和IP type3或者IP3发送给server。在另一种可能实现方式中，UE发生移动得到新IP地址IP3后，CP可以根据该IP3或位置信息2判断是否需要将位置信息2和IP type3或者IP3发送给server。只有当UE发生移动后新分配的IP地址IP3不在IP地址段1内或者UE移出位置区1，CP才将位置信息2和IP type3或者IP3发动给server。
408、server接收UE的位置信息2和IP type3或者IP3，并判断是否需要进行APP列表更新，如果需要，则获取该IP type3对应的IP地址段2或者该IP type3对应的位置区2绑定的APP列表2，向UE发送该APP列表2，该位 置区2由该位置信息2确定，该IP地址段2为终端发生移动后所在IP地址段，位置区2为终端发生移动后所在位置区。
在本发明实施例中，用APP列表2来指代第二应用列表，用位置区2来指代第二位置区，用IP地址段2来指代第二IP地址段。
对应步骤407中，server接收UE的位置信息2和IP type3或者IP3可能是由UE发送，也可能是由CP发送，下面针对这两种发送方式对APP列表更新的判断进行介绍：
针对第一种发送方式，该第一种发送方式事实上可以包括UE只要发生移动得到新IP地址IP3就将位置信息2和IP type3或者IP3发送给server，和，只有当UE发生移动后新分配的IP地址IP3不在IP地址段1内或者UE移出位置区1才将位置信息2和IP type3或者IP3发动给server两种情况。
在第一种发送方式的第一种情况下，当server接收到UE的位置信息2和IP type3或者IP 3时，可以根据该IP 3确定IP地址段2，根据该位置信息2确定位置区2。Server在确定IP地址段2或者位置区2后，可以判断IP地址段2或者位置区2对应的管理平台上部署的应用与UE在移动前的IP地址段1或者位置区1对应的管理平台上部署的应用是否相同，如果相同，则不需要进行APP列表更新，如果不相同，则需要进行APP列表更新。
在第一种发送方式的第二种情况下，由于UE是在新分配的IP地址IP3不在IP地址段1内或者UE移出位置区1时才向server发送UE的位置信息2和IP type3或者IP 3，因此，当server接收到UE的位置信息2和IP type3或者IP 3时，就可以确定需要进行APP列表更新。
针对第二种发送方式，该第二种发送方式事实上可以包括UE只要发生移动得到新IP地址IP3，CP就将位置信息2和IP type3或者IP3发送给server，和，只有当UE发生移动后新分配的IP地址IP3不在IP地址段1内或者UE移出位置区1，CP才将位置信息2和IP type3或者IP3发动给server两种情况。
在第二种发送方式的第一种情况下，APP列表更新的判断与在第一种发送方式的第一种情况同理。
在第二种发送方式的第二种情况下，APP列表更新的判断与在第一种发送方式的第二种情况同理。
Server在判断需要进行APP列表更新后，可以根据该IP地址段2或者位置区2，从本地存储的至少一个APP列表中，获取根据该IP地址段2或者位 置区2对应的管理平台上的APP生成的APP列表2。
获取APP列表2后，将IP type1对应的IP地址段1或者IP type1对应的位置区1与APP列表1之间的绑定关系更新为IP type3对应的IP地址段2或者该IP type3对应的位置区2与APP列表2之间的绑定关系，并将该APP列表2发送给UE。
本发明实施例是以server向UE发送APP列表2为例进行说明，实际上，server还可以将APP列表2发送给CP，并由CP将该APP列表2发送给UE。
409、UE接收server返回的APP列表2，当UE针对APP列表2中的APP发起业务时，根据该业务对应的APP选择IP地址段2内的IP或者IP type3的IP地址作为源IP地址。
该步骤中选择IP地址的过程与步骤405类似，例如，在本发明实施例中，当UE通过APP2发起通信请求时，根据该APP2查询本地已存储的至少一个APP列表，如果该APP2位于本地已存储的APP列表2中时，确定该APP列表2，并获取该APP列表2所绑定的IP地址段2或者IP type3，从已有的IP地址，IP3和IP2中选择该IP地址段2内的IP3或者该IP type3的IP3，在后续业务过程中，可以使用该IP3进行路由，与APP2对应的服务器进行通信。
步骤408和步骤409是以server根据UE的位置信息2和IP type3或者IP3，确定IP地址段2或者位置区2后，判断需要进行APP列表更新为例进行说明的。如果server判断不需要进行APP列表更新，说明IP地址段2或者位置区2对应的管理平台上部署的应用与UE在移动前的IP地址段1或者位置区1对应的管理平台上部署的应用相同。
此情况下，server不需要获取应用列表2，也不需要向UE发送该应用列表2，而UE则直接使用原来的APP列表，例如APP列表1，当UE针对APP列表1中的APP发起业务时，可以选择IP地址段1内的IP或者IP type1的IP地址作为源IP地址，即从移动后UE的IP地址，IP2和IP3中选择IP3作为源IP地址，在后续业务过程中，可以使用该IP3进行路由。
本发明实施例提供的方法，将IP类型对应的IP地址段或IP类型对应的位置区与APP列表绑定，当针对该APP列表中的应用发起业务时可以选择该IP地址段内的IP或该IP类型的IP地址进行路由，解决了终端需要和多个APP分别进行绑定的问题，信令较少。
另外，UE发生移动后，将移动后UE的位置信息和IP类型或者IP发送 给server，由server根据移动后的IP地址段或者位置区，判断移动后的管理平台上部署的应用与移动前的管理平台上部署的应用是否相同，进而确定是否需要将IP类型对应的IP地址段或IP类型对应的位置区与APP列表之间的绑定关系进行更新，如果不需要，则直接使用原来的APP列表，如果需要更新时，则直接更新绑定关系，并将更新的APP列表发送给UE。避免了UE发生移动重新选择本地用户面网关时，进行UE新分配的IP地址和本地应用服务器上部署的多个应用分别进行绑定的问题，信令较少。
另外，UE发生移动后，UE根据移动后新分配的IP或者移动后UE的位置信息，判断移动后新分配的IP所在IP地址段或者UE所在位置区，是否与移动前IP所在IP地址段或者UE所在位置区相同，进而确定是否需要将移动后UE的位置信息和IP类型或者IP发送给server，当server接收到移动后UE的位置信息和IP类型或者IP时，获取更新的APP列表并发送给UE。信令较少、通信时延较短。
图4对应的实施例解决的是UE发生移动后，可能导致需要更新APP列表的情况，而管理平台上APP增加或者减少时也会导致APP列表需要更新。下面将在图5对应的实施例中对管理平台上APP增加或者减少时更新APP列表的情况进行说明。
图5是本发明实施例提供的一种多宿主场景下进行路由的方法的流程示意图。参见图5，包括：
501、server根据至少一个管理平台上部署的APP，生成该至少一个管理平台的APP列表。
502、UE通过建立PDU连接，得到IP1和IP2，IP1和IP2的IP类型分别为IP type1和IP type2。
503、UE向server发送UE的位置信息1和IP type1或者IP 1。
504、server接收UE的位置信息1和IP type1或者IP 1，并将IP type1对应的IP地址段1或者IP type1对应的位置区1绑定的APP列表1发送给UE。
505、UE接收server返回的APP列表1，当UE针对该APP列表1中的APP发起业务时，根据该业务对应的APP选择IP地址段1内的IP或者IP type1的IP地址作为源IP地址。
上述步骤501至505与步骤401至405同理。
506、当管理平台上部署的APP发生变化时，该管理平台向server发送APP变更通知。
管理平台上部署了某一个地域范围内的多个APP，当该地域范围内增加了新APP时，则可以将该新APP部署上来，当该地域范围内原有的旧APP不再使用了，则可以将该旧APP删除，这两种情况都会导致管理平台上部署的APP发生变化。
在本发明实施例中，当管理平台有新APP部署或者旧APP删除时，管理平台可以向server发送APP变更通知，将APP增减的情况通知server。
507、如果server接收到APP变更通知，则获取APP列表3，该APP变更通知用于指示APP列表1更新为APP列表3。
如果该APP变更通知为第一通知，该第一通知用于指示管理平台上有新部署的APP。server会根据APP列表1中的APP和新部署的APP，生成新APP列表，作为APP列表3；
如果该APP变更通知为第二通知，该第二通知用于指示管理平台上有旧APP删除。server会根据APP列表1，从APP列表1中删除旧APP，得到新APP列表，作为APP列表3。
例如：如果管理平台上有新APP部署时，则会向server发送APP增加的通知，server在接收到该通知后，则根据APP列表1中的APP和新部署的APP，生成新APP列表，作为APP列表3；如果管理平台上有旧APP删除时，则会向server发送APP减少的通知，server在接收到该通知后，则根据APP列表1，从APP列表1中删除旧APP，得到新APP列表，作为APP列表3。
508、Server解除APP列表1与IP type1对应的IP地址段1或者IP type1对应的位置区1之间的绑定关系，并将APP列表3与IP type1对应的IP地址段1或者IP type1对应的位置区1绑定，并向UE发送APP列表3。
Server在获取APP列表3后，将IP type1对应的IP地址段1或者IP type1对应的位置区1与APP列表1之间的绑定关系解除，将IP type1对应的IP地址段1或者该IP type1对应的位置区1与APP列表3绑定，并将该APP列表3发送给UE。
509、UE接收server返回的APP列表3，当UE针对APP列表3中的APP发起业务时，根据该业务对应的APP选择IP地址段1内的IP或者IP type1的IP地址作为源IP地址。
该步骤509与步骤409同理，故不再赘述。
本发明实施例提供的方法，server通过与管理平台的交互，可以实时地接收管理平台发送的APP变更通知，从而更新APP列表，并将原绑定关系解除后建立新的绑定关系，解决了管理平台上APP增加或者减少时更新APP列表的情况，APP增加或者减少时就将绑定关系进行更新，时效性强。
图4和图5对应的实施例中，server是绑定关系建立和更新的执行主体，而该执行主体还可以为其他功能模块，图6对应的实施例将对CP代替服务器来执行相应步骤的过程进行说明。
图6是本发明实施例提供的一种多宿主场景下进行路由的方法的流程示意图。参见图6，包括：
601、CP根据至少一个管理平台上部署的APP，生成该至少一个管理平台的APP列表。
602、UE通过建立PDU连接，得到IP1和IP2，IP1和IP2的IP类型分别为IP type1和IP type2。
603、UE向CP发送UE的位置信息1和IP type1或者IP 1。
604、CP接收UE的位置信息1和IP type1或者IP 1，并将IP type1对应的IP地址段1或者IP type1对应的位置区1绑定的APP列表1发送给UE，该位置区1由该位置信息1确定。
605、UE接收CP返回的APP列表1，当UE针对该APP列表1中的APP发起业务时，根据该业务对应的APP选择IP地址段1内的IP或者IP type1的IP地址作为源IP地址。
606、当管理平台上部署的APP发生变化时，则向CP发送APP变更通知。
607、如果CP接收到APP变更通知，则获取APP列表3。
608、CP解除APP列表1与IP type1对应的IP地址段1或者IP type1对应的位置区1之间的绑定关系，并将APP列表3与IP type1对应的IP地址段1或者IP type1对应的位置区1绑定，并向UE发送APP列表3。
609、UE接收CP返回的APP列表3，当UE针对APP列表3中的APP发起业务时，根据该业务对应的APP选择IP地址段1内的IP或者IP type1的IP地址作为源IP地址。
上述步骤601至609与步骤501至509同理。
本发明实施例提供的方法，CP通过与管理平台的交互，可以实时地接收管理平台发送的APP变更通知，从而更新APP列表，并将原绑定关系解除后建立新的绑定关系，解决了管理平台上APP增加或者减少时更新APP列表的情况，APP增加或者减少时就将绑定关系进行更新，时效性强。
