具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1示出了本公开一个示例性实施例提供的5G通信系统的框图。该通信系统可以是基于NR的5G系统，也包含基于演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，eUTRAN)的5G系统以及5G系统的后续演进系统。该通信系统被定义为支持数据连接和服务，以便于网络部署时能够使用诸如网络功能虚拟化(NFV)和软件定义网络(SDN)之类的技术。该通信系统主要有网络功能(Network Function，NF)组成，采用分布式的功能来根据实际需要部署。新的网络功能的加入和撤出，并不影响整体网络的功能。该通信系统包括：用户设备(3GPP对移动终端的命名)(User Equipment，UE)、(无线)接入网络((R)AN)、用户平面功能(User Plane Function，UPF)、数据网络(Data Network，DN)和控制平面功能。
其中，控制平面功能包括：接入和移动管理功能(AMF)、会话管理功能(SMF)、控制策略功能(PCF)和统一数据管理(UDM)。
UE通过空中接口与RAN通信。RAN与UPF之间通过第一参考点N3通信。两个UPF之间通过第二参考点N9通信。PSA UPF与DN之间通过第三参考点N6通信。
上述UE、RAN、UPF和DN均可能为多个。当UPF为多个时，存在一些UPF是UE的PDU会话锚用户平面功能(PSA UPF)。两个PDU会话锚用户平面功能(PSA UPF)之间通过第四参考点N19通信(图1中未示出)。
UE和AMF之间通过第五参考点N1通信。RAN和AMF之间通过第六参考点N2通信。UPF和SMF之间通过第七参考点N4通信。
在图1所示的网络架构中，包括如下参考点：
N1：UE和AMF之间的参考点；
N2：(R)AN和AMF之间的参考点；
N3：(R)AN和UPF之间的参考点；
N4：SMF和UPF之间的参考点；
N6：PSA UPF和数据网络之间的参考点；
N9：两个UPF之间的参考点；
N14：两个AMF之间的参考点；
N19：5G LAN型业务的两个PSA UPF之间的参考点(图中未示出)。
在图1所示的网络架构中，包括如下基于服务的接口：
N amf：AMF展示的基于服务的接口；
N smf：SMF展示的基于服务的接口；
N pcf：PCF展示的基于服务的接口；
N udm：UDM展示的基于服务的接口。
虚拟网络群组的通信包括一对一通信和一对多通信。一对一通信支持在虚拟网络群组内的两个UE之间或一个UE和一个在DN上的设备之间转发单播通信。一对多通信支持将广播数据从一个UE(或DN上的设备)转发到虚拟网络群组内的全部UE和DN上的设备，或者，将广播数据从一个UE(或DN上的设备)转发到虚拟网络群组内的部分UE和DN上的设备。
其中，广播通信是指虚拟网络群组中的一个成员(UE或设备)发出的广播数据，必须要传递到虚拟网络群组中每个成员。基于上述图1所示的核心网架构，本申请实施例支持广播 通信的三种通信方式：
第一，本地交换方式(基于第一参考点N3或第二参考点N9)；
当虚拟网络群组的成员包括连接到同一个PSA UPF的两个UE时，两个UE之间的广播数据直接在PSA UPF内部进行交换，而无需将广播数据发送到第三参考点N6之外，再被外部路由器或交换机将数据返回来。
结合参考图2，UE1与RAN1通信，RAN1与中间UPF1通信；UE2与RAN2通信，RAN2与中间UPF2通信。UE1和UE2均连接到同一个PSA UPF，当UE1发送广播数据包时，直接在PSA UPF内部进行广播数据包的交换，从而将广播数据包发送至UE2，无需将广播数据包发送到第三参考点N6之外。
第二，基于第三参考点N6的方式；
当虚拟网络群组的成员包括一个UE和DN上的一个设备时，对于UE和设备之间的广播数据需要通过N6来交换。
结合参考图3，UE1与RAN1通信，RAN1与UPF1通信，PSA UPF1与DN通信。当UE1发送广播数据包时，需要通过N6将广播数据包传递至DN上的设备3。
第三，基于第四参考点N19的方式。
当虚拟网络群组的成员包括连接到不同PSA UPF的两个UE时，两个UE之间的广播数据需要通过第四参考点N19来交换，两个PSA UPF之间建立有N19隧道。
结合参考图4，UE1与RAN1通信，RAN1与中间UPF1通信；UE4与RAN2通信，RAN2与中间UPF2通信。UE1和UE4分别连接到不同的PSA UPF：PSA UPF1和PSA UPF2，两个PSA UPF之间建立有N19隧道，当UE1发送广播数据包时，需要经过两个PSA UPF之间的N19隧道进行广播数据包的交换，从而将广播数据包发送至UE4。
图5示出了本申请一个示例性实施例提供的虚拟网络群组的广播方法的流程图。该方法可以由UPF来执行。该方法包括：
步骤501，UPF接收虚拟网络群组的一个成员发送的广播数据包，广播数据包的目的地址是广播地址；
广播数据包是通过目标IP地址或目的MAC地址来确定的。示例性的，广播数据包中的目的IP/MAC地址是广播地址(如IPv4广播地址是255.255.255.255或192.168.1.255，广播MAC地址是FF:FF:FF:FF:FF:FF)，同一个虚拟网络群组中的广播地址可以存在多个(比如3个或5个)，多个广播地址可构成一个广播地址列表。一个广播数据包中的目的地址是广播地址列表中的一个广播地址即可。
步骤502，UPF将广播数据包发送至至少两个广播内部接口中的目标广播内部接口；
PSA UPF中提供有至少两个广播内部接口。结合图6所示，至少两个广播内部接口包括：
第一广播内部接口：用于接收本地成员通过N3/N9发送的广播数据包，通过N3/N9、N6、N19来发送至虚拟网络群组的全部其他成员(可选包括发送成员本身)。以5G系统为例，第一广播内部接口可称为5G VN BC internal R，或者其他名称。
第二广播内部接口：用于将非本地成员通过N6/N19发送的广播数据包，通过N3/N9来发送至虚拟网络群组在PSA UPF的全部本地成员。以5G系统为例，第二广播内部接口可称为5G VN BC internal C，或者其他名称。
可选地，本地成员包括在该虚拟网络群组中以当前UPF为PDU会话锚点的UE。
步骤503，UPF通过目标广播内部接口将广播数据包发送至虚拟网络群组的全部成员或全部本地成员。
综上所述，本实施例提供的方法，通过在UPF提供至少两个广播内部接口，当接收到某一个成员的广播数据包时，先发送到至少两个广播内部接口中的目标广播内部接口，再通过目标广播内部接口发送至虚拟网络群组的全部成员或全部本地成员，能够实现虚拟网络群组中的广播通信。
对于虚拟网络群组中的每个PSA UPF，PSA UPF的至少两个广播内部接口至少存在如下不同的实现方式：
第一种实现方式：两个广播内部接口；
第一广播内部接口和第二广播内部接口；
第二种实现方式：三个广播内部接口；
第一广播内部接口、第二广播内部接口和第三广播内部接口；
第三种实现方式：多个广播内部接口；
1个第一广播内部接口和n个第二广播内部接口，每个第二广播内部接口对应一个广播地址，n为广播地址的数量；
或，1个第一广播内部接口、n个第二广播内部接口、n个第三广播内部接口，每个第二广播内部接口对应一个广播地址，每个第三广播内部接口对应一个广播地址，n为广播地址的数量；
或，n个第一广播内部接口、n个第二广播内部接口，每个第一广播内部接口对应一个广播地址，每个第二广播内部接口对应一个广播地址，n为广播地址的数量；
或，n个第一广播内部接口、n个第二广播内部接口、n个第三广播内部接口，每个第一广播内部接口对应一个广播地址，每个第二广播内部接口对应一个广播地址，每个第三广播内部接口对应一个广播地址，n为广播地址的数量。
以下实施例中采用单个PSA UPF的角度来对上述广播内部接口进行描述，但是整个广播数据包的传递过程可能涉及到多个PSA UPF，每个PSA UPF的处理过程相同或类似，通过多个PSA UPF的传递来实现整个虚拟网络群组中的广播通信，本文中不对每个PSA UPF均一一赘述。
针对上述第一种实现方式：
参考图7，示出了本申请一个示例性实施例提供的虚拟网络群组的广播方法的流程图。该方法可以由UPF来执行，该方法包括：
步骤701，UPF接收虚拟网络群组的一个成员发送的广播数据包，广播数据包的目的地址是广播地址；
设发送广播数据包的成员为成员A，成员A可以是虚拟网络群组中的任一成员。当虚拟网络群组中存在多个广播地址时，广播数据包的目的地址是多个广播地址中的一个广播地址。
成员A是UPF的本地成员时，UPF通过N3或N9接收成员A的广播数据包；成员A是UPF的非本地成员时，UPF通过N6或N19接收成员A的广播数据包。
步骤702，当广播数据包是来自第一参考点或第二参考点的广播数据时，UPF将广播数据包发送至第一广播内部接口；
当UPF接收到本地成员通过N3或N9发送的广播数据包时，将该广播数据包发送至第一广播内部接口。
步骤703，UPF通过第一广播内部接口将广播数据包从虚拟网络群组中每个成员分别对应的第一参考点或第二参考点或第三参考点或第四参考点，发送至虚拟网络群组的全部成员；
成员A发送广播数据包，当成员B是与成员A连接到同一PSA UPF的成员时，第一广播内部接口将广播数据包通过成员B对应的N3或N9发送至成员B；当成员C是DN上的设备时，第一广播内部接口将广播数据包通过成员C对应的N6发送至成员C；当成员D是与成员A连接到不同的PSA UPF的成员时，第一广播内部接口将广播数据包通过成员D对应的N19发送至成员D，如图8所示。
需要说明的是，本步骤中的“全部成员”可以包括发送该广播数据包的成员，也可以不包括发送该广播数据包的成员。
步骤704，当广播数据包是来自第三参考点或第四参考点的广播数据时，UPF将广播数据包发送至第二广播内部接口；
当UPF接收到非本地成员通过N6或N19发送的广播数据包时，将该广播数据包发送至第二广播内部接口。
步骤705，UPF通过第二广播内部接口将广播数据包从UPF的每个本地成员分别对应的第一参考点或第二参考点，发送至UPF的全部本地成员。
如图8给出的一个示例，当成员C发送广播数据包时，PSA UPF1接收来自N6的广播数据包，将其放入到其第二广播内部接口，然后通过第二广播内部接口将广播数据包通过成员A对应的N9发送至成员A，通过成员B对应的N9发送至成员B。PSA UPF2同样也会接收到来自N6的广播数据包，将其放入到其第二广播内部接口，然后通过其第二广播内部接口将广播数据包通过成员D对应的N3发送至成员D。这样，成员C发出的广播数据包发送到全部成员。
如图8给出的另一示例，当成员A发送广播数据包时，PSA UPF1接收来自N9的广播数据包，将其放入到其第一广播内部接口，通过第一广播内部接口将广播数据包从成员B对应的N9接口发送至成员B(PSA UPF1也可以根据网络配置将该广播数据包从N9接口发送到成员A自己)，从N6接口发送至DN的成员C，从N19接口发送至PSA UPF2。PSA UPF2接收来自N19的广播数据包，将其放入到其第二广播内部接口，然后通过第二广播内部接口将此广播数据包通过N3接口发送至本地成员D。这样，成员A发出的广播数据包发送到全部成员。
综上所述，本实施例提供的方法，通过在UPF提供第一广播内部接口，当接收到本地成员的广播数据包时，将本地成员的广播数据包先发送到第一广播内部接口，再通过第一广播内部接口发送至虚拟网络群组的全部成员(在除当前UPF之外的路径上，还有可能需要继续通过其它UPF的第二或第三广播内部接口，才能发送到至虚拟网络群组的全部成员)，能够实现虚拟网络群组中的广播通信。
本实施例提供的方法，通过在UPF提供第二广播内部接口，当接收到非本地成员的广播数据包时，将非本地成员的广播数据包先发到第二广播内部接口，再通过第二广播内部接口发送至连接到UPF的全部本地成员，既能够实现虚拟网络群组中的广播通信，还能够避免不必要的流量转发，节省网络传输资源。
基于图7的可选实施例中，虚拟网络群组内的广播流量转发的实现过程如下：对于虚拟网络群组内的每个UPF，使用UPF内的至少两个广播内部接口。通过两步检测在每个UPF的广播内部接口之间进行广播数据包的转发。
在第一步中，安装在UPF中的PDR规则检测从任何虚拟网络群组内的成员(通过N3或N9或N6或N19)接收的广播数据包，并且应用UPF中的FAR规则，将广播数据包转发到UPF的广播内部接口，也即为广播内部接口设置的目的接口。
在第二步中，安装在UPF的广播内部接口中的PDR规则检测到广播数据包，当广播数据包匹配PDR规则后，就应用广播内部接口中对应的FAR规则，通过N3或N6或N9或N19将广播数据包转发给相应的虚拟网络群组的全部成员或全部本地成员。
因此，对于虚拟网络群组内的每个UPF中配置有N4规则(也即，PDR规则和FAR规则)，PDR规则和FAR规则的示例性配置如下：
第一PDR规则和第一FAR规则
SMF为虚拟网络群组的每个成员的N4会话(也即与每个成员的PDU会话相对应的N4会话)提供有第一PDR规则和第一FAR规则，以便UPF处理从该UE接收的广播数据包。

为了检测流量，第一PDR规则包括：源接口设置为接入侧，目标地址设置为广播地址列 表，核心网隧道信息设置为PDU会话的第一参考点或第二参考点的隧道头(包括N3或N9接口对应的上行IP地址和上行GTP-U TEID信息)，GTP-U TEID是GPRS隧道协议端点标识(GPRS Tunnel Protocol Tunnel Endpoint Identifier)的缩写。

对于虚拟网络群组中的每个UPF(或存在需要的UPF)，UPF中设置有与组级别会话对应的第二PDR规则和第二FAR规则。通过所述第二PDR规则检测到广播数据包是来自第三参考点N6的广播数据时，通过第二FAR规则将广播数据包发送至第二广播内部接口，如图9所示。

对于虚拟网络群组中的每个UPF，UPF中设置有与每个本地成员对应的第四PDR规则和第四FAR规则。UPF通过第四PDR规则检测到广播数据包是来自第一广播内部接口的广播数据时，通过第四FAR规则将广播数据包从虚拟网络群组的每个成员分别对应的第一参考点或第二参考点或第三参考点或第四参考点，发送至虚拟网络群组的全部成员，如图9所示。
为了检测流量，第四PDR规则包括：源端口设置为第一广播内部接口，目标地址为广播地址列表；
为了转发流量，对应于本地成员，第四FAR规则包括：外部头创建指示第一参考点N3或第二参考点N9的隧道信息(包括N3或N9接口对应的下行IP地址和下行GTP-U TEID信息)，目标接口为接入侧；或，对应于DN上的设备，第四FAR规则还包括：外部头创建指示第三参考点N6的信息，目标接口为核心侧；或，对应于N19隧道相连的成员，第四FAR规则还包括：外部头创建指示第四参考点N19的隧道信息(包括N19接口对应的对方PSA UPF的IP地址和GTP-U TEID信息)，目标接口为核心侧。
第五PDR规则和第五FAR规则

针对上述第二种实现方式：
参考图10，示出了本申请一个示例性实施例提供的虚拟网络群组的广播方法的流程图。该方法可以由UPF来执行，该方法包括：
步骤1001，UPF接收虚拟网络群组的一个成员发送的广播数据包，广播数据包的目的地址是广播地址；
设发送广播数据包的成员为成员A，成员A可以是虚拟网络群组中的任一成员。当虚拟网络群组中存在多个广播地址时，广播数据包的目的地址是多个广播地址中的一个广播地址。
成员A是UPF的本地成员时，UPF通过N3或N9接收成员A的广播数据包；成员A是UPF的非本地成员时，UPF通过N6或N19接收成员A的广播数据包。
步骤1002，当广播数据包是来自第一参考点或第二参考点的广播数据时，UPF将广播数据包发送至第一广播内部接口；
当UPF接收到本地成员通过N3或N9发送的广播数据包时，将该广播数据包发送至第一广播内部接口。
步骤1003，UPF通过第一广播内部接口将广播数据包从虚拟网络群组中每个成员分别对应的第一参考点或第二参考点或第三参考点或第四参考点，发送至虚拟网络群组的全部成员；

需要说明的是，本步骤中的“全部成员”可以包括发送该广播数据包的成员，也可以不包括发送该广播数据包的成员。
步骤1004，当广播数据包是来自第三参考点的广播数据时，UPF将广播数据包发送至第二广播内部接口；
当UPF接收到非本地成员通过N6发送的广播数据包时，将该广播数据包发送至第二广播内部接口。
步骤1005，UPF通过第二广播内部接口将广播数据包从UPF的每个本地成员分别对应的第一参考点或第二参考点，发送至UPF的全部本地成员。
如图8给出的一个示例，当成员C发送广播数据包时，PSA UPF1接收来自N6的广播数据包，将其放入到自身的第二广播内部接口，然后通过第二广播内部接口将广播数据包通过成员A对应的N9发送至成员A，通过成员B对应的N9发送至成员B。PSA UPF2同样也会接收到来自N6的广播数据包，将其放入到其第二广播内部接口，然后通过自身的第二广播内部接口将广播数据包通过成员D对应的N3发送至成员D。这样，成员C发出的广播数据包发送到全部成员。
步骤1006，当广播数据包是来自第三参考点的广播数据时，UPF将广播数据包发送至第三广播内部接口；
当UPF接收到非本地成员通过N19发送的广播数据包时，将该广播数据包发送至第三广 播内部接口。
步骤1007，UPF通过第三广播内部接口将广播数据包从UPF的每个本地成员分别对应的第一参考点或第二参考点，发送至UPF的全部本地成员。
如图8给出的另一示例，当成员A发送广播数据包时，PSA UPF1接收来自N9的广播数据包，将其放入到自身的第一广播内部接口，通过第一广播内部接口将广播数据包从成员B对应的N9接口发送至成员B(PSA UPF1也可以根据网络配置将这个数据从N9接口发送到成员A自己)，从N6接口发送至DN的成员C，从N19接口发送至PSA UPF2。PSA UPF2接收来自N19的广播数据包，将其放入到自身的第三广播内部接口，然后通过第三广播内部接口将此广播数据包通过N3接口发送至本地成员D。这样，成员A发出的广播数据包发送到全部成员。
综上所述，本实施例提供的方法，通过在UPF提供第一广播内部接口，当接收到本地成员的广播数据包时，将本地成员的广播数据包先发送到第一广播内部接口，再通过第一广播内部接口发送至虚拟网络群组的全部成员，能够实现虚拟网络群组中的广播通信。

本实施例提供的方法，通过在UPF提供第三广播内部接口，当接收到来自N19的非本地成员的广播数据包时，将非本地成员的广播数据包先发到第三广播内部接口，再通过第三广播内部接口发送至连接到UPF的全部本地成员，既能够实现虚拟网络群组中的广播通信，还能够避免不必要的流量转发，节省网络传输资源。
基于图10的可选实施例中，虚拟网络群组内的广播流量转发的实现过程如下：对于虚拟网络群组内的每个UPF，使用UPF内的至少两个广播内部接口。通过两步检测在每个UPF的广播内部接口之间进行广播数据包的转发。
在第一步中，安装在UPF中的PDR规则检测从任何虚拟网络群组内的成员(通过N3或N9或N6或N19)接收的广播数据包，当广播数据包匹配PDR规则时，应用UPF中的FAR规则将广播数据包转发到UPF的广播内部接口，也即为广播内部接口设置的目的接口。
在第二步中，安装在UPF的广播内部接口中的PDR规则检测到广播数据包，当广播数据包匹配PDR规则后，就应用广播内部接口中对应的FAR规则，通过N3或N6或N9或N19将广播数据包转发给虚拟网络群组的全部成员或全部本地成员。
因此，对于虚拟网络群组内的每个UPF中配置有N4规则(也即，PDR规则和FAR规则)，PDR规则和FAR规则的示例性配置如下：
第一PDR规则和第一FAR规则
SMF为虚拟网络群组的每个成员的N4会话(也即与每个成员的PDU会话相对应的N4会话)提供有第一PDR规则和第一FAR规则，以便UPF处理从该UE接收的广播数据包。
对于虚拟网络群组中的每个UPF，UPF中设置有与每个本地成员对应的第一PDR规则和第一FAR规则。UPF通过第一PDR规则检测到广播数据包是来自第一参考点N3或第二参考点N9的广播数据时，通过第一FAR规则将广播数据包发送至第一广播内部接口，如图11所示。
为了检测流量，第一PDR规则包括：源接口设置为接入侧，目标地址设置为广播地址列表，核心网隧道信息设置为PDU会话的第一参考点或第二参考点的隧道头(包括N3或N9接口对应的上行IP地址和上行GTP-U TEID信息)；
为了转发流量，第一FAR规则包括：目标接口设置为第一广播内部接口。

PDR规则和FAR规则的配置过程
上述PDR规则和FAR规则由SWF向相应的UPF配置。图12示出了本申请一个示例性实施例提供的虚拟网络群组的广播方法的流程图。该方法可以由SMF来执行，该方法包括：
步骤1202，SMF生成PDR规则和FAR规则；

根据上述实施例可知，至少两个广播内部接口存在多种实现方式。

可选地，当UPF是虚拟网络群组中的成员第一次选中的UPF时，向每个被第一次选中 的UPF配置：组级别的N6接口相关的第二PDR规则和第二FAR规则，以及第五PDR规则和第五FAR规则。
需要说明的是，因为虚拟网络群组中的成员可能为多个，则选中的UPF也可能是多个，各个UPF与DN之间使用N6接口相连接。
当至少两个广播内部接口包括第二广播内部接口时，上述步骤1202和步骤1204可实现成为如下步骤，如图15所示：
步骤1202c，SMF生成第三PDR规则和第三FAR规则，以及第五PDR规则和第五FAR规则；
其中，有关“第三PDR规则和第三FAR规则”、“第五PDR规则和第五FAR规则”的介绍，可参考上述实施例中的描述，本实施例不再赘述。
步骤1204c1，当UPF是被选中且UPF是虚拟网络群组中的成员选中的第N个UPF时，在虚拟网络群组中的成员所选中的第1个至第N-1个UPF中的每个UPF和第N个UPF之间，建立与虚拟网络群组对应的群组级第四参考点，N为大于或等于2的整数；
可选地，当UPF是第一次被选中且UPF是虚拟网络群组中的成员选中的第N个UPF时，在虚拟网络群组中的成员所选中的第1个至第N-1个UPF中的每个UPF和第N个UPF之间，建立与虚拟网络群组对应的群组级第四参考点N19隧道。
示例性的结合参考图8，当PSA UPF2是成员D第一次被选中的UPF，且PSA UPF2是被虚拟网络群组中的成员选中的第2个UPF(已经存在PSA UPF1是被虚拟网络群组中的成员选中的第1个UPF)，则PSA UPF2与PSA UPF1建立N19GTP-U隧道。

需要说明的是，负责将N6，N19接收到的广播数据包发送到广播内部接口，以及从广播内部接口发出的数据转发给N6，N19的PDR，FAR，是虚拟网络群组所使用的组级别的4 个N4会话，即是独立于每个UE的N4会话(一个UE建立一个PDU会话就有一个PDU会话级别的N4会话)，也就是这4个N4会话是所有虚拟网络群组的成员都共同使用的N4会话(功能相当于这4个会话要被虚拟网络群组的所有成员来使用，但无需单独为每个成员来定义)。
在一个示例性的例子中，图17示出了UE请求的PDU会话建立的流程图(用于非漫游和本地疏导漫游场景)。有关该附图的细节描述可参考3GPP中的标准23.502中的附图4.3.2.2.2的描述，本文不再赘述。
针对图13所示出的配置过程，虚拟网络群组中的每个UE都需要建立一个PDU会话。针对虚拟网络群组中的每个UE，SMF可以在步骤10a的N4会话过程中“也即SMF向UPF发送的N4会话建立/修改请求中”，将第一PDR规则、第一FAR规则、第四PDR规则和第四FAR规则配置到UPF中。
针对图14所示出的配置过程，若是UPF是第一个被虚拟网络群组中的成员选中的UPF时，SMF可以在步骤8的“UPF选择过程”中，对每个UE的第一个选中的UPF中，将虚拟网络群组对应的群组级别的N6接口相关的第二PDR规则、第二FAR规则、第五PDR规则和第五FAR规则下发到该UPF中。
针对图15所示出的配置过程，若是UPF是第一次被选中，且是第N(N>＝2)个被虚拟网络群组的成员使用的UPF，SMF可以在步骤8的“UPF选择过程”中，在从第一个到第N-1个已经选中的每个UPF中建立虚拟网络群组对应的群组级别的与第N个UPF的N19接口，并且创建与第N个UPF之间的N19接口相关的第三PDR规则、第三FAR规则、第五PDR规则和第五FAR规则下发到此第1个到第N-1个UPF中。
另外，SMF在从第N个已经选中的UPF中创建与第1个到第N-1个UPF之间的N19接口相关的第三PDR规则、第三FAR规则、第五PDR规则和第五FAR规则下发到此第N个UPF中。
针对图16所示出的配置过程，若是UPF是第一次被选中，且是第N(N>＝2)个被虚拟网络群组的成员使用的UPF，SMF可以在步骤8的“UPF选择过程”中，在从第一个到第N-1个已经选中的每个UPF中建立虚拟网络群组对应的群组级别的与第N个UPF的N19接口，并且创建与第N个UPF之间的N19接口相关的第六PDR规则、第六FAR规则、第七PDR规则和第七FAR规则下发到此第1个到第N-1个UPF中。
另外，SMF在从第N个已经选中的UPF中创建与第1个到第N-1个UPF之间的N19接口相关的第六PDR规则、第六FAR规则、第七PDR规则和第七FAR规则下发到此第N个UPF中。
其中，有关“第一PDR规则和第一FAR规则”、“第二PDR规则和第二FAR规则”、“第三PDR规则和第三FAR规则”、“第四PDR规则和第四FAR规则”、“第五PDR规则和第五FAR规则”、“第六PDR规则和第六FAR规则”、“第七PDR规则和第七FAR规则”的介绍，可参考上述实施例中的描述，本实施例不再赘述。
在一个示例性的例子中，图18示出了UE请求的PDU会话建立的流程图(用于归属路由漫游场景)。针对图13或图14或图15或图16所示出的配置过程，是在图18中的步骤10“UPF选择过程”以及步骤12a“N4会话创建请求”中执行的，而非步骤4“UPF选择过程”和步骤5“N4会话创建请求”中执行。有关该图18的细节描述可参考3GPP中的标准23.502中的附图4.3.2.2.2-1的描述，本文不再赘述。
上述第一种实现方式和第二种实现方式中，PDR规则和FAR规则中包含有广播地址列表。当广播地址列表发生改变(增加、修改或删除)时，所有的PDR规则和FAR规则全部需要修改。
由于一个虚拟网络群组中的成员较多，若只修改一个广播地址就需要SMF对全部成员的 UPF进行信令修改，造成很多的信令开销。因为这个广播地址列表是所有的规则中都存在的。
因此，可以对前面的PDR规则和FAR规则进行优化，所有成员与组级别的规则共用同一个广播地址列表。所以，本申请提出：1)虚拟网络群组的成员与群组级别的PDR规则和FAR规则，是每个UPF共享同一个广播地址列表。2)当共用的这个广播地址发生改变(增加，修改或删除)时，只需要对虚拟网络群组的所有UPF修改这个共用的广播地址列表即可。这个广播地址列表发生改变(增加，修改或删除)时，就实现了全部群组成员的所有规则的修改，从而大大地节省了信令。
也即，该方法还包括如下步骤：
当需要新增广播地址列表中的广播地址时，SMF指示不同的UPF中的任一UPF对共用地址列表新增广播地址；或，当需要修改广播地址列表中的广播地址时，SMF指示不同的UPF中的任一UPF对共用地址列表修改广播地址；或，当需要删除广播地址列表中的广播地址时，SMF指示不同的UPF中的任一UPF对共用地址列表删除广播地址。
图19示出了UE或网络请求的PDU会话修改的流程图(用于非漫游和本地疏导漫游场景)。SMF修改广播地址列表的过程，可以在步骤2a、步骤8a和步骤12a中的任一步骤中执行。有关图19的细节描述可参考3GPP中的标准23.502中的附图4.3.2.2.2的描述，本文不再赘述。
图20示出了UE或网络请求的PDU会话修改的流程图(用于归属路由漫游场景)。SMF修改广播地址列表的过程，可以在H-SMF和H-UPF之间的步骤或16a中执行。有关图20的细节描述可参考3GPP中的标准23.502中的附图4.3.2.2.2-1的描述，本文不再赘述。

至少两个广播内部接口包括第一广播内部接口时，若一个成员从UPF移动到另一UPF时，SMF将该成员对应的第一PDR规则和第一FAR规则，以及第四PDR规则和第四FAR规则在新建或重定位的PDU会话上运行。
由于旧UPF上该成员的上下文全部删除，因此旧UPF还将该成员的第一PDR规则和第一FAR规则，以及第四PDR规则和第四FAR规则全部删除。
步骤2102，当一个成员从UPF移动到另一UPF，且另一UPF是被选中时，SMF向另一UPF配置第二PDR规则和第二FAR规则，以及第五PDR规则和第五FAR规则；

步骤2103，当一个成员从UPF移动到另一UPF，且另一UPF是被选中时，SMF向另一UPF配置第三PDR规则和第三FAR规则，以及第五PDR规则和第五FAR规则；
至少两个广播内部接口包括第二广播内部接口时，若一个成员从UPF移动到另一UPF时，SMF向另一UPF配置群组级别的第三PDR规则和第三FAR规则，以及第五PDR规则和第五FAR规则。
一个示例中，若一个成员从UPF移动到另一UPF且另一UPF是第一次被选中时，SMF向另一UPF配置群组级别的第三PDR规则和第三FAR规则，以及第五PDR规则和第五FAR规则。
由于旧UPF上该成员的上下文全部删除，，若UE是旧UPF上的最后一个虚拟网络群组 的成员，则旧UPF上的群组级别的第三PDR规则和第三FAR规则，以及第五PDR规则和第五FAR规则删除。
步骤2104，当一个成员从UPF移动到另一UPF，且另一UPF是被选中时，SMF向另一UPF配置第六PDR规则和第六FAR规则，以及第七PDR规则和第七FAR规则。

一个示例中，若一个成员从UPF移动到另一UPF且另一UPF是第一次被选中时，SMF向另一UPF配置群组级别的第六PDR规则和第六FAR规则，以及第七PDR规则和第七FAR规则。
由于旧UPF上该成员的上下文全部删除，若UE是旧UPF上的最后一个虚拟网络群组的成员，则旧UPF上的群组级别的第六PDR规则和第六FAR规则，以及第七PDR规则和第七FAR规则删除。
上述四个步骤的执行先后顺序不限，且每个步骤可以互相独立执行，本申请实施例对此不加以限定。
其中，有关“第一PDR规则和第一FAR规则”、“第二PDR规则和第二FAR规则”、“第三PDR规则和第三FAR规则”、“第四PDR规则和第四FAR规则”、“第五PDR规则和第五FAR规则”、“第六PDR规则和第六FAR规则”、“第七PDR规则和第七FAR规则”的介绍，可参考上述实施例中的描述，本实施例不再赘述。
