具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
在当前通信网络***中，核心网与移动终端之间的通信可以通过卫星链路实现。然而，由于卫星链路通常会带来高延时，而如果终端的某些业务的延时要求得不到满足，会导致业务无法正常响应。因此，核心网需要确定终端对应的卫星链路信息，以为该终端配置合适的服务质量标识，从而能够满足终端的业务需求。例如，在某些特殊情况下，比如，当终端位于孤岛、孤立森林、山区等偏僻的地区，需要使用卫星链路，如果按照严苛的低延时服务质量标准，卫星链路可能无法响应某些业务，从而不能满足实际需求。在本公开的实施例中，可以针对这种情况，为终端配置合适的服务质量标识，从而确保终端的业务能够得到正常响应。
图1示出了根据本公开实施例的一种卫星链路信息确定方法的流程示意图。该方法由UPF网元执行，以便确定终端对应的卫星链路信息。如图1所示，该卫星链路信息确定方法可以包括以下步骤：
S101，基于终端所在小区的信息以及UPF网元对应的网络部署信息来确定终端对应的卫星链路信息。
小区的信息包括以下信息中的至少一种：小区的标识、小区所属的接入网节点标识。网络部署信息包括指示卫星链路是否可用于UPF网元与接入网节点的互连的第一部署信息以及指示卫星链路是否可用于接入网节点与终端的互连的第二部署信息。卫星链路信息包括以下信息中的至少一种：与UPF网元和接入网节点的互连有关的卫星回程信息，与接入网节点和终端的互连有关的卫星接入信息。
在当前的移动通信网络***中，可以存在多种网络部署情况。例如，在可使用卫星链路的通信网络***中，存在如下网络部署：在第一种网络部署中，在UPF网元与接入网节点之间的互连可以采用卫星链路实现，可称为卫星回程链路；在第二种网络部署中，在接入网节点与终端之间的互连可以采用卫 星链路实现，可称为卫星接入链路；在第三种网络部署中，在UPF网元与接入网节点之间的互连以及在接入网节点与终端之间的互连均可以采用卫星链路实现，可称为卫星回程+卫星接入链路。
在如上所述的可使用卫星链路的网络部署中，UPF网元可以根据终端所在小区的信息以及网络部署信息来确定终端对应的卫星链路信息。其中，终端所在小区的信息可以包括小区的标识和/或小区所属接入网节点(例如，基站)的标识。网络部署信息可以指示UPF网元所属网络采用的网络部署情况，例如，可以包括第一部署信息，其指示卫星链路是否可用于该UPF网元与对应接入网节点的互连，以及第二部署信息，其指示卫星链路是否可用于接入网节点与终端的互连。

本公开实施例中，可以基于终端所在小区的信息以及网络部署信息确定终端当前对应的卫星链路信息，以便于核心网能够根据终端当前对应的卫星链路信息，为终端配置对应的服务质量标识，从而满足终端的业务需求。
图2示出了根据本公开实施例的一种卫星链路信息确定方法的流程示意图。该方法由UPF网元执行，以便确定终端对应的卫星链路信息。基于图1所示实施例，如图2所示，该卫星链路信息确定方法可以包括以下步骤：
S201，基于终端所在小区的信息以及UPF网元对应的网络部署信息来确定终端对应的卫星链路信息。
小区的信息包括以下信息中的至少一种：小区的标识、小区所属的接入网节点标识。网络部署信息包括指示卫星链路是否可用于UPF网元与接入网节点的互连的第一部署信息以及指示卫星链路是否可用于接入网节点与终端的互连的第二部署信息。卫星链路信息包括以下信息中的至少一种：与UPF网元和接入网节点的互连有关的卫星回程信息，与接入网节点和终端的互连有关的卫星接入信息。
在本公开的实施例中，步骤S201的具体实现可参考以上图1所示的步骤S101的实现方式，本公开实施例对此不再赘述。
S202，将终端对应的卫星链路信息发送至会话管理功能SMF网元。
UPF网元在为终端确定了卫星链路信息之后，可以将该卫星链路信息发送至SMF网元，以便SMF网元也能够获知终端对应的卫星链路信息。
在一些实施例中，步骤S202可以通过如下来实现：响应于来自SMF网元的分组数据单元会话建立请求或分组数据单元会话修改请求，向SMF网元发送终端对应的卫星链路信息。
参见图3所示，在会话建立流程中，例如，在N4会话建立流程中，SMF网元可以触发建立分组数据单元(PDU，package data unit)会话或重定位UPF，并将PDU会话建立请求发送个UPF网元，UPF网元响应于该PDU会话建立请求(N4会话建立请求)，向SMF网元发送PDU会话建立响应(N4会话建立响应)，从而实现会话建立。在本实施例中，UPF网元可以将终端对应的卫星链路信息携带在PDU会话建立响应中以发送给SMF网元，从而使得SMF网元获知终端的卫星链路信息。

S301，向与UPF网元对应的接入网节点发送终端信息订阅请求，终端信息订阅请求指示接入网节点将与接入网节点建立互连的终端所在小区的信息发送给UPF网元；和/或从与UPF网元对应的接入网节点接收与接入网节点建立互连的终端所在小区的信息。
在本实施例中，UPF网元可以向接入网节点(例如，基站)发送终端信息订阅请求，而终端信息订阅请求指示接入网节点将通过该接入网节点接入通信网络***的终端所在小区的信息发送给UPF网元。接入网节点响应于该终端订阅请求，将通过该接入网节点接入通信网络***的终端所在小区的信息发送给UPF网元。在另一实施例中，接入网节点可以主动将通过该接入网节点接入通信网络***的终端所在小区的信息发送给UPF网元。
例如，UPF网元可以向与其对应的基站发送终端信息订阅请求以便从基站获取与该基站建立互连的终端所在小区的信息。例如，基站1在从UPF网元接收到终端信息订阅请求后，若基站1发现终端UE1、UE2、UE3处于该基站1的覆盖范围内，例如UE1在基站1的小区A内而UE2和UE3在基站1的小区B内，则基站1可以将UE1、UE2、UE3所在小区的信息发送给UPF网元。例如，针对UE1，可以向UPF网元发送基站1的标识或小区A的标识，而针对UE2和UE3，可以向UPF网元发送基站1的标识或小区B的标识，从而UPF网元能够获知哪些终端通过该基站1接入通信网络***。
