Abstract

本发明公开了一种关于流迁移触发的相关实现方法，所述方法包括：用户设备(UE)向网络侧发送流迁移触发方式相关的信息，所述流迁移触发方式相关的信息用于网络侧决定流迁移触发方式；接收网络侧所决定的流迁移触发方式指示信息。本发明还同时公开了另一种关于流迁移触发的相关实现方法、设备及存储介质。

Description

一种关于流迁移触发的相关实现方法、设备及存储介质 技术领域
本发明涉及通信中的业务流处理技术，尤其涉及一种关于流迁移触发的相关实现方法、设备及存储介质。
背景技术
随着无线局域网络(Wireless Local Area Networks，WLAN)接入技术的日益成熟，以及用户对高速无线接入网络的需求，国内外运营商都在大力发展WLAN业务；WLAN业务作为蜂窝数据网络的分流手段，其作用也越来越重要。
流迁移(IP Flow Mobility，IFOM)技术可以实现IP业务流在不同接入***之间的迁移，用户设备(User Equipment，UE)可以根据网络拥塞状况和策略对业务流路由路径进行修改，从而保证通信质量、改善用户体验。流迁移原理示意图，如图1所示，UE通过第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)接入***和非3GPP(如WLAN)接入***连接到同一分组数据网络(Packet Data Network，PDN)，通过3GPP网络的业务流包括Web业务流和文件传输协议(File Transfer Protocol，FTP)流；其中，线1表示IP语音VoIP业务流，线2表示Conv.video传统视频业务流，线3表示Non-conv.video非传统视频业务流，线4表示Web网页业务流，线5表示FTP文件传输业务流；当UE移动到WLAN信号覆盖较弱的区域时，通过WLAN传输的业务流质量受到影响，此时，UE发起将Web流从WLAN迁移到3GPP的IFOM流程以保证Web应用的传输质量。Web流成功迁移后的流迁移原理示意图如图2所示，Web业务流的路径变更为从3GPP网络传输。
IFOM根据用户使用的移动性管理协议类型分为基于主机的移动性管理协议，如：基于Dual-Stack Mobile IPv6(DSMIPv6)的IFOM和基于网络的移动性管理协议(Network-based IP flow mobility，NB-IFOM)，如：基于隧道协议/代理移动IPv6协议(GPRS Tunnelling Protocol/Proxy Mobile IPv6，GTP/PMIPv6GPRS)的流迁移。其中，基于DSMIPv6的IFOM方案已经在3GPP支持；具体地，UE和网络通过DSMIPv6的信令进行IFOM信息的协商，完成信令协商后，UE和网络对对应的IFOM路由规则信息做修改和更新。这里，基于DSMIPv6的IFOM的发起都是由UE侧执行的；UE可以同时通过3GPP接入网和非3GPP接入网(如WLAN接入网)同时接入到同一个分组数据网络网关(Packet Data Network Gateway，P-GW)，P-GW为UE分配一个IP地址，分配的IP地址同时在3GPP网络和非3GPP网络上使用，支持业务数据流在3GPP网络和非3GPP网络之间的迁移；如：在UE同时接入3GPP网络和非3GPP网络期间，UE发生移动后不在非3GPP网络的覆盖区域内，但仍在3GPP网络的覆盖区域内，则可以将通过非3GPP网络接入的业务迁移到3GPP网络；或者，非3GPP网络拥塞时，UE可以将实时性要求高的业务迁移到3GPP网络。
目前，3GPP在研究支持NB-IFOM的IFOM；具体地，UE使用GTP/PMIPv6通过3GPP网络和非3GPP网络(如：WLAN)在演进分组核心网(Evolved Packet Core，EPC)建立PDN连接，在3GPP网络和非3GPP网络上分配相同的IP地址，UE和网络之间可以进行流迁移策略的更新，在实现3GPP网络和非3GPP网络上的流迁移。在这个过程中，UE通知网络当前建立的连接是为IFOM建立，网络支持IFOM时，将IFOM指示回复给UE。IFOM策略的更新，如：新增、删除、或修改可以由UE侧发起，也可以由网络侧发起。
由UE侧发起IFOM的场景包括：UE根据接入网络发现和选择功能 (Access Network Discovery and Selection Function，ANDSF)提供的IFOM更新策略向网络发起IFOM请求、UE在第一时间感知空口环境的变化，根据信号强度发起IFOM请求、在UE上进行配置更新发起IFOM请求等；由网络侧发起IFOM的场景包括：网络侧根据运营商的预配置策略发起IFOM请求、运营商根据网络侧当前的拥塞情况更新IFOM策略，发起IFOM请求等；但是，UE侧发起的IFOM和网络侧发起的IFOM的场景需求不同，UE侧触发IFOM和网络侧触发IFOM如何协商工作是目前尚未解决的问题。

为更好地理解本实施例所述技术方案，下面介绍TWAN接入EPC网络的相关知识。
3GPP演进的分组***(Evolved Packet System，EPS)由E-UTRAN、MME、服务网关(Serving Gateway，S-GW)、P-GW或PDN GW、归属用户服务器(Home Subscriber Server，HSS)、策略和计费规则功能(Policy and Charging Rules Function，PCRF)实体及其他支撑节点组成。
3GPP从Rel-11阶段开始研究支持WLAN作为信任的接入网络为UE提供到EPC的连接。在Rel-11阶段，主要研究对UE没有影响的方案，UE通过WLAN网络只能建立单条分组数据连接，并且不支持UE在WLAN接入网和3GPP接入网之间进行分组数据连接的结合；其中，通过WLAN网络建立的单条分组数据连接可以是到EPC网络的分组数据连接，也可以是从WLAN网络直接连到数据网络的有缝WLAN流量迁移(NSWO，Non-seamless WLAN offload)连接。
目前，3GPP在Rel-12阶段研究支持TWAN接入EPC网络对用户设备有影响的方案，此方案要求兼容通过信任的WLAN接入网络连接到EPC的移动性(S2a Mobility Over Trusted WLAN access to EPC，R11SaMOG)的方案，支持多PDN的连接、切换等流程，支持传递接入点名称(Access Point Name，APN)、PDN类型等信息，支持同时通过WLAN接入EPC网络和WLAN业务分流的场景，UE能够向网络侧指示UE是否支持接入EPC网 络或者NSWO网络，网络侧能够向UE指示接入EPC网络或者NSWO的决策结果。
