具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的技术方案中所涉及的移动网络可以是以下任一种：全球移动通讯(Global System of Mobile communication，简称GSM)系统，码分多址(Code Division Multiple Access，简称CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，简称WCDMA)系统，通用分组无线业务(General Packet Radio Service，简称GPRS)系统，长期演进(Long Term Evolution，简称LTE)系统，通用移动通信系统(Universal Mobile Telecommunications System，简称UMTS)等，本发明对此不做限定。目前移动网络在实际部署中又可分为宏基站部署与微基站部署。宏基站覆盖范围大，每个宏基站下可包含多个宏小区。微基站覆盖范围小，通常一个微基站只负责一个微小区。运营商可以通过封闭用户组(Closed Subscriber Group，简称 CSG)对终端设备能否接入微基站进行控制。随着无线接入技术的发展，现有技术中还存在如授权辅助接入(Licensed Assisted Access，简称LAA)等无线接入技术。
WLAN可以分为公共WLAN和私有WLAN，也可以分为可信WLAN和非可信WLAN。
本发明实施例应用于移动网络和WLAN接入方式共存的场景，UE同时支持这两种接入方式。
下面介绍本发明实施例所涉及到的分流策略。
系统间路由策略ISRP：不同网络系统之间的分流策略，比如蜂窝网络与WLAN网络之间的流粒度或接入点名称(Access Point Name，简称APN)粒度的分流策略，适用于支持多接入的UE。图1为本发明一实施例提供的ISRP分流策略的示意图，该ISRP分流策略包括：以流为粒度的分流节点，以服务为粒度的分流节点，非无缝分流节点，漫游节点，公共陆地移动网(Public Land Mobile Network，简称PLMN)节点，更新测量节点，其中，以流为粒度的分流节点包括基于流粒度的分流策略，以服务为粒度的分流节点包括基于APN粒度的分流策略，非无缝分流节点包括非无缝分流到WLAN网络的策略，漫游节点指示该ISRP策略是否应用于漫游场景，PLMN节点指示下发策略的PLMN信息，更新测量节点用于指示策略更新方式，如UE主动更新或网络侧主动更新等。图2为本发明一实施例提供的ISRP策略中以服务为粒度的分流节点的示意图，其中以服务为粒度的分流节点包括：有效区域节点、路由标准节点、移动网络位置节点和WLAN位置节点。其中，有效区域节点用于指示策略生效的区域、路由标准节点包括策略生效的区域条件或/和时间条件等、移动网络位置节点包括蜂窝网络位置信息，WLAN位置节点包括WLAN网络位置信息；路由规则节点包括相关的路由规则，优先接入节点包括优先接入的网络方式。
系统间移动策略ISMP：不同网络系统之间的路由策略，比如蜂窝网络与WLAN网络之间所有数据流的路由策略，适用于支持单接入的UE。
接入点间路由策略IARP是APN选择策略。
无线局域网选择策略WLANSP是WLAN网络选择策略。其中ISMP、IARP和WLANSP包括的节点与ISRP类似，在此不再赘述。
进一步地，上述ISRP、ISMP、IARP和WLANSP策略中所包含的节点可分为策略条件节点与策略执行节点。其中，策略条件节点决定了该策略是否生效，而策略执行节点指示用户设备应如何分流。以ISRP中的以服务为粒度的分流节点为例，其中策略条件节点包括：流描述信息如APN，有效区域节点，时间节点及RAN有效条件等。当用户设备当前所在位置、RAN侧状态，时间等信息与策略条件节点中的有效区域节点，时间节点及RAN有效条件等相匹配，且等待分流的流信息与流描述信息的APN相匹配，则此策略生效。策略执行节点包括：路由规则节点等。此节点中包含接入技术、接入网标识与接入网优先级。终端设备可以从路由规则节点中获取优先级最高的接入技术。后续终端设备将等待分流的数据流从上述接入技术发送给网络侧。此外，策略中还包含策略优先级。

S302：UE获知UE的当前网络连接状态；
其中，UE的当前网络连接状态包括：所述UE当前接入的是宏小区、微小区、CSG小区或者LAA小区；和/或，UE当前接入的是公共WLAN、私有WLAN、可信WLAN或者非可信WLAN。
S303：UE根据当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息；若满足，则UE根据分流策略对数据进行分流。
具体地，UE判断当前网络连接状态是否与分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息一致，若一致，则UE根据分流策略对数据进行分流。其中，可以采用现有技术的任何分流方法进行数据分流，本发明实施例对此不做限制。
本发明实施例中的分流策略可以是系统间路由策略ISRP、系统间移动策略ISMP、接入点间路由策略IARP、无线局域网选择策略WLANSP及接入网发现划分信息等，通常网络设备根据UE当前的网络连接状态向UE确定发送哪种分流策略。并且一般发送的分流策略可以为至少一条。因此，存在两种情况：一种是UE接收网络设备发送的至少一条分流策略，该分流策略包含优先级信息；则UE根据当前网络连接状态，按照分流策略优先级高低对分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息进行匹配；若满足，则UE根据满足的分流策略对数据进行分流。另一种是UE接收网络设备发送的至少一条分流策略；UE根据当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息；若满足，则将对应的分流策略作为有效分流策略；所述UE根据优先级最高的有效分流策略对数据进行分流。
进一步地，UE根据分流策略对数据进行分流，包括：UE根据分流策略将数据分流至移动网络或WLAN网络。由于本发明实施例的分流策略中增加了移动网络的划分信息和/或WLAN的划分信息，那么在最后执行数据分流时，自然会分流至细化后的移动网络和/或WLAN中，比如：增加了宏小区指示信息，当UE满足分流策略中的所有条件，则UE最后通过移动网络接入方式进行分流，实质为通过对应小区为宏小区的移动网络接入方式进行数据分流。本发明对数据分流的方式不做限制。更进一步地，宏小区指示信息、微小区指示信息、封闭用户组CSG信息、授权辅助接入LAA指示信息、公共WLAN指示信息或者私有WLAN指示信息、可信WLAN指示信息或者非可信WLAN指示信息都对应有相应的优先级，比如：宏小区指示信息的优先级为1、公共WLAN的优先级为4，由于公共WLAN的优先级高于宏小区指示信息的优先级，则UE采用优先级更高的公共WLAN进行数据分流。
本发明实施例提供一种数据分流方法，包括：UE接收网络设备发送的分流策略，该分流策略包括：移动网络的划分信息和/或WLAN网络的划分信 息；UE获知所述UE的当前网络连接状态；根据所述当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息；若满足，则UE根据分流策略对数据进行分流。相对于现有技术中分流策略只能将数据分流至移动网络和WLAN中，数据分流的灵活性更高，比如：UE可以根据分流策略通过宏小区对应的移动网络和公共WLAN进行数据分流，也有可能是通过微小区对应的移动网络和私有WLAN进行数据分流。
进一步地，由于分流策略包括至少一个策略条件节点和至少一个策略执行节点，因此，移动网络的划分信息和WLAN的划分信息可以携带在策略条件节点或者策略执行节点中。
一种可选方式，分流策略包括：有效区域节点、路由标准节点、移动网络位置节点和WLAN位置节点中的至少一个；其中，移动网络的划分信息携带在有效区域节点、路由标准节点或者移动网络位置节点中的任一个之中；WLAN的划分信息携带在WLAN位置节点之中。比如：结合图2所示，其中移动网络的划分信息携带在有效区域节点移动网络位置节点中；WLAN的划分信息携带在WLAN位置节点之中。
进一步地，分流策略还包括：条件指示信息；该条件指示信息用于指示UE需要满足条件指示信息所在的节点所包括的所有条件；或者，条件指示信息用于指示所述UE需要满足条件指示信息所在的节点所包括的至少一个条件；所述条件指示信息所在的节点为有效区域节点、路由标准节点、移动网络位置节点和WLAN位置节点中的至少一个。比如：条件指示信息所在的节点是有效区域节点，该条件指示信息可以为1或者0，其中1表示UE需要满足有效区域节点的所有条件，0通用于指示所述UE需要满足有效区域节点所包括的至少一个条件，通常有效区域节点包括：移动网络位置节点和WLAN位置节点，其中移动网络位置节点中包括一个条件是宏小区指示信息，WLAN位置节点中包括的是公共WLAN指示信息，那么当条件指示信息为1时，则UE需要同时接入宏小区和公共WLAN才能满足有效区域节点中的所有节点，当条件指示信息为0时，则UE只需要接入宏小区和公共WLAN中的至少一个即可。
另一种可选方式，所述分流策略包括：路由规则节点和/或优先接入节点；其中，所述移动网络的划分信息和所述WLAN的划分信息分别携带在所述路 由规则节点或者所述优先接入节点中。如图2所示，以服务为粒度的分流节点还包括：路由规则节点和优先接入节点；其中，移动网络的划分信息可以携带在路由规则节点或者优先接入节点中，WLAN的划分信息也可以携带在路由规则节点或者优先接入节点中。
需要说明的是，针对IARP分流策略，移动网络的划分信息通常不携带在路由规则节点或者优先接入节点中，WLAN的划分信息通常不携带在路由规则节点或者优先接入节点中。
可选地，上述宏小区指示信息或者微小区指示信息包括小区的标识列表。则UE获知UE的当前网络连接状态，包括：若UE接收到基站发送的UE当前接入的小区的标识，获知UE当前接入小区的标识对应的小区；则UE根据当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息，包括：UE判断所述小区的标识是否属于所述宏小区指示信息或者所述微小区指示信息所包括的小区的标识列表。
可选地，上述宏小区指示信息包括宏小区类型，则UE获知所述UE的当前网络连接状态，包括：若所述UE接收到基站发送的UE当前接入的小区的标识；且若所述UE确定所述当前接入的小区标识中基站标识的长度为第一比特值，该第一比特值通常为20比特，获知所述UE当前接入的是宏小区；则所述UE根据所述当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息，包括：所述UE判断所述分流策略中是否包括所述宏小区指示信息。
同样地，上述微小区指示信息包括微小区类型，则UE获知所述UE的当前网络连接状态，包括：若所述UE接收到基站发送的UE当前接入的小区的标识；且若所述UE确定所述当前接入的小区标识中基站标识的长度为第二比特值，该第二比特值通常为28比特，获知所述UE当前接入的是微小区；则所述UE根据所述当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息，包括：所述UE判断所述分流策略中是否包括所述微小区指示信息。
可选地，封闭用户组CSG信息包括CSG标识列表，则UE获知所述UE的当前网络连接状态，包括：若所述UE接收到基站发送的第一CSG标识，获知所述UE当前属于所述第一CSG标识对应的CSG小区；则所述UE根据 所述当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息，包括：所述UE判断所述第一CSG标识是否属于分流策略的CSG信息中的CSG标识列表。进一步地，CSG信息也可以包括的是CSG模式，其中CSG模式包括：开放模式、封闭模式和混合模式，所谓UE需要满足CSG信息这个条件，即UE所对应的CSG模式要与CSG信息中的CSG模式一致；当然，CSG信息可以同时包括CSG标识和CSG模式，所谓UE需要满足CSG信息这个条件，即UE所对应的CSG标识和CSG模式都要满足CSG信息这个条件。
可选地，UE获知所述UE的当前网络连接状态，包括：所述UE接收基站发送的第一指示消息，所述第一指示消息用于指示所述UE当前接入的频段；若所述UE当前接入的频段在预设频段范围内，该预设频段范围为现有技术中LAA可以所属的任一频段范围，则所述UE获知所述UE当前接入的是LAA小区；则所述UE根据所述当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息，包括：所述UE判断所述分流策略中是否包括所述LAA指示信息。
可选地，所述UE获知所述UE的当前网络连接状态，包括：所述UE接收接入点AP发送的第二指示消息，所述第二指示消息用于指示所述UE当前接入的WLAN类型；所述WLAN类型包括：公共WLAN、私有WLAN，可信WLAN或非可信WLAN；所述UE根据所述第二指示消息获知所述UE当前接入的是公共WLAN、私有WLAN、可信WLAN或非可信WLAN；则所述UE根据所述当前网络连接状态判断是否满足分流策略所包含的移动网络的划分信息和/或WLAN网络的划分信息，包括：所述UE根据所述UE当前接入的WLAN类型判断是否与所述分流策略中的WLAN指示信息一致。比如：第二指示消息指示UE当前接入的WLAN类型为公共WLAN，那么若WLAN的划分信息为公共WLAN指示信息，则确定UE当前接入的WLAN类型与分流策略中的WLAN指示信息一致。否则，则不一致。
本发明实施例中由于分流策略包括：移动网络的划分信息和/或WLAN的划分信息；那么UE在进行数据分流时可以进一步地分流至细化后的某个移动网络和/或某个WLAN中，相对于现有技术中分流策略只能将数据分流至移动网络和WLAN中，数据分流的灵活性更高，比如：UE可以根据分流 策略通过宏小区对应的移动网络和公共WLAN进行数据分流，也有可能是通过微小区对应的移动网络和私有WLAN进行数据分流。
