由于在S512之前,未建立有第二终端与所述网络设备之间的第二连接,因此,所述业务切换响应消息中包含第二连接的第二连接规则,能够建立第二终端与所述网络设备之间的第二连接,并且,通过第二连接向第二终端12发送业务数据的网络功能,与S512之前向第一终端11发送目标业务数据的网络功能为同一网络功能,上述目标路由规则中的第二包过滤器能够识别出之前发送给第一设备的目标业务数据包,第二路由规则中的下行路由规则确保将所述目标数据业务包发送给第二设备的第二链接(可选的,第二QoS流),或者同时发送给第一设备的第一链接(可选的,第一QoS流)和第二设备的第二链接(可选的,第二QoS流),由此保证因特网业务在一个用户的多设备上切换时的业务连续性。
在一种实现方式中,在将接收目标业务数据的设备由所述第一终端11变更为第一终端11和第二终端12的情况下,网络设备向所述请求方终端发送的业务切换响应消息包含:上述第二连接的第二连接规则,并且,由于变更后第一终端11也保持接收目标业务数据,因此,第一连接的状态无需作出变化,即无需释放或修改第一连接。
S516:第二终端根据切换指示,接收目标网络功能发送的目标业务数据。
在另一种实现方式中,在将接收目标业务数据的设备变更为仅第二终端12的情况下,所述方法还包括:
S528:网络设备向所述第一终端11发送第一连接释放消息或第一连接修改消息。
其中,第一连接释放消息用于释放所述第一终端11与所述网络设备之间的第一连接。所述第一连接消息指示用于修改所述第一连接的第一连接规则,以停止所述目标网络功能向所述第一终端12的数据发送。由此,停止所述目标业务数据在目标网络功能与所述第一终端11之间的数据发送,实现将接收目标业务数据的设备由第一终端11变更为仅第二终端12一个设备。
本发明实施例提供的一种传输业务数据的方法,通过向网络设备发送业务切换请求,其中,所述业务切换请求用于将接收目标业务数据的设备由第一终端11变更为第二终端12,所述业务切换请求中包括:被请求方终端的标识信息,所述被请求方终端为所述第一终端11和所述第二终端12中除所述请求方终端之外的终端;接收网络设备发送的业务切换响应消息,能够保证因特网业务在一个用户的多设备上切换时的业务连续性。
如图6所示,本发明的一个实施例提供一种传输业务数据的方法600,该方法可以由终端设备和/或网络设备执行,换言之,该方法可以由安装在终端设备和/或网络设备的软件或硬件来执行,该方法包括如下步骤:
S610:请求方终端向网络设备发送移动性管理请求消息。
请求网络授权,可以包括:向网络设备发送移动性管理请求消息,其中,移动性管理请求消息中包括:用于请求获取终端间业务切换服务的第一指示标识和/或用于表征支持终端间业务切换服务能力的第二指示标识,由此,使所述请求方终端获取终端间业务切换服务能力。请求方终端可以为第一终端11也可以为第二终端12。即第一终端11和第二终端12可以各自向网络设备发送移动性管理请求消息以获取各自的终端间业务切换服务能力。
在一种实现方式中,所述移动性管理请求消息中还包括:被请求方终端的终端标识。
网络设备接收所述请求方终端发送的移动性管理请求消息。
S621:网络设备向所述请求方终端发送移动性管理响应。
请求方终端接收所述网络发送的移动性管理响应。所述移动性管理响应 中包括:用于表征网络允许所述请求方终端获取终端间业务切换服务能力的网络信令。第一终端11和第二终端12之间均需向网络请求授权,以获取终端间业务切换服务。由此使得所述第一终端11和所述第二终端12为具有获取终端间业务切换服务能力的终端,并且在此基础上执行以下步骤。
例如,第一终端11在移动管理过程中向网络请求终端间切换(inter UE transfer)业务或者指示支持inter UE transfer能力,网络在响应消息中接受第一终端11请求的Inter UE transfer业务请求或者指示网络支持Inter UE transfer能力,并同时提供令牌(token)给第一终端11。第一终端11将token提供给第二终端12。第二终端12在移动性管理过程中向网络提供从第一终端11处获得的token,网络设备通过判断token为之前网络提供给第一终端11的token,判断出所述第一终端11和所述第二终端12为具有获取终端间业务切换服务能力的终端,关联两设备的上下文,可以为两设备提供inter UE transfer业务。
此外,确定是否可以为两设备提供inter UE transfer业务也可以包括其他实现方式。
例如,第一终端11在移动性管理过程中向网络设备提供第二终端12的标识和特定指示,例如上述inter UE transfer相关指示(请求终端间切换(inter UE transfer)业务或者指示支持inter UE transfer能力),该指示表明第二终端12是第一终端11的信任终端,设备2可以与第一终端11一起获得inter UE transfer的业务;第二终端12在移动性管理过程中向网络设备提供第一终端11的标识和特定指示,例如上述inter UE transfer相关指示(请求终端间切换(inter UE transfer)业务或者指示支持inter UE transfer能力),该指示表明第一终端11是第二终端12的信任终端,第二终端12可以与第一终端11一起获得inter UE transfer的业务;网络设备在第一终端11和第二终端12的上下文中记录信任设备的标识和inter UE transfer相关指示,以关联两个设备的上下文。
例如,第一终端11和第二终端12两设备同属于同一用户,在设备各自的签约中表明了该设备属于同一用户,可以进行inter UE Transfer业务。当其他网络设备从签约数据管理功能实体获得相关签约,可以判断第一终端11和第二终端12互为可信终端,关联两设备的上下文,可以为两设备提供inter UE transfer业务。
例如,设备1和设备2通过例如无线保真(WIFI)、蓝牙、无线通信等传递各种标识信息,该标识信息包括但不限于:第一终端11的标识,第一连接标识PDU会话标识,QoS流标识,APN,数据网络名(Data Network Name,DNN),切片(slice),映射切片(mapped slice)标识和token等等。

在一种实现方式中,所述业务切换请求中还包括:终端间切换指示,所述终端间切换指示用于表征终端请求目标业务数据在所述第一终端11和所述第二终端12中切换。

S623:确定所述第一终端11和所述第二终端12是否为具有获取终端间业务切换服务能力的终端。
本步骤可以包括:根据所述业务切换请求中携带的终端间切换指示,通过网络设备本地存储的第一终端和第二终端的上下文,确定所述第一终端11和所述第二终端12是否为具有获取终端间业务切换服务能力的终端,并且在确定所述第一终端11和所述第二终端12为具有获取终端间业务切换服务能力的终端的情况下,执行步骤S624。
例如,AMF收到inter UE transfer指示后,判断设备1是否与设备2有关联关系,是否可以进行inter UE transfer业务;判断的方法可以是通过判断本地第一设备和第二设备的上下文中有inter UE transfer指示和/或对方设备的标识,或者是通过查询UDM签约服务器中得知两设备可以进行inter UE Transfer业务等。
S624:网络设备确定向所述第一终端发送目标业务数据的目标网络功能。
本步骤可采用图2-4实施例相应步骤S224、324或424的描述,在此不再赘述。
