下面结合附图，对本公开实施例的具体实施方式进行详细说明。
图1示出了可以应用于本公开实施例的语音唤醒方法或语音唤醒装置的示例性系统架构的示意图。
如图1所示，该系统架构包括节点、基站104和网络设备105，其中，节点包括终端设备101、至少一个第一中继102和第二中继103，终端设备101的用户面数据也可以通过第一中继102转发到第二中继103，再通过第二中继103转发后接入基站104，网络设备105通过基站104获取用户面数据，并对其进行统计。此外，第一中继102和第二中继103都有可能需要通过基站104进行独立的通信，网络设备105通过基站104获取第一中继102和第二中继103的用户面数据，并对其进行统计。
此外，节点包括终端设备101和第二中继103(这种情况没有在图1中示出)，终端设备101的用户面数据可以直接发送给第二中继103，再通过第二中继103转发后接入基站104，网络设备105通过基站104获取用户面数据，并对其统计。
节点和基站104之间以及基站104与网络设备105之间通过网络连接，网络可以是有线网络，也可以是无线网络。
在一些实施例中，上述的无线网络或有线网络使用标准通信技术和/或协议。网络通常为因特网、但也可以是任何网络，包括但不限于局域网(Local Area Network，LAN)、城域网(Metropolitan Area Network，MAN)、广域网(Wide Area Network，WAN)、移动、有线或者无线网络、专用网络或者虚拟专用网络的任何组合)。在一些实施例中，使用包括超文本标记语言(Hyper Text Mark-up Language，HTML)、可扩展标记语言 (Extensible MarkupLanguage，XML)等的技术和/或格式来代表通过网络交换的数据。此外还可以使用诸如安全套接字层(Secure Socket Layer，SSL)、传输层安全(Transport Layer Security，TLS)、虚拟专用网络(Virtual Private Network，VPN)、网际协议安全(Internet ProtocolSecurity，IPsec)等常规加密技术来加密所有或者一些链路。在另一些实施例中，还可以使用定制和/或专用数据通信技术取代或者补充上述数据通信技术。
在一些实施例中，不同的终端设备101、第一中继102、第二中继103中安装的应用程序的客户端是相同的，或基于不同操作系统的同一类型应用程序的客户端。基于终端平台的不同，该应用程序的客户端的具体形态也可以不同，比如，该应用程序客户端可以是手机客户端、PC客户端等；
在一些实施例中，本公开实施例中的终端设备101、第一中继102和第二中继103也可以称作UE(User Equipment，用户终端)，在具体实现时，终端设备101、第一中继102和第二中继103可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备。

本公开实施例中提供了一种多跳近域通信统计方法，网络设备105根据获取到的多个节点的中继服务发现信息生成各个节点的用户面数据特征信息；根据各个节点的用户面数据特征信息构建各个节点的过滤对应关系表，过滤对应关系表用于表示各个节点的用户面数据特征信息和与各个节点对应的用户面功能UPF网元的处理策略之间的对应关系，以使各个节点对应的UPF网元对接收到的用户面数据进行转发或通信统计。
该方法可以应用在近域通信场景中，例如针对高频蜂窝覆盖进行扩展的近域通信场景中、由蜂窝网提供集中控制的多跳近域通信场景等，在蜂窝网提供集中控制的多跳近域通信场景中，终端设备101(远端UE)通过单跳或者多跳，经过第二中继103(U2N Relay)转发后接入蜂窝网，使远端UE和蜂窝网络得以保持通信连接的应用场景中。本公开节点对应的UPF网元对接收到的用户面数据进行通信统计，计量方便，且每个节点产生的通信数据单独计量，计量精度高。
本领域技术人员可以知晓，图1中的节点、基站104和网络设备105的数量仅仅是示意性的，根据实际需要，可以具有任意数目的节点、基站104和网络设备105。本公开实施例对此不作限定。

其中，不同用户面数据特征信息对应不同的处理策略，过滤对应关系表预设在SMF网元或中间会话管理功能I-SMF网元上，过滤对应关系表上存储有用户面数据特征信息和处理策略的对应关系，根据用户面数据特征信息查询过滤对应关系表，得到对应的处理策略。

每个节点对应一个PSA-UPF网元，I-UPF网元根据PDR用于区分不同节点的用户面数据，并根据FAR将不同节点的用户面数据转发到与节点对应的PSA-UPF网元上，并在PSA-UPF网元上完成通信统计。
本公开在受蜂窝网络控制的近域通信系统中，终端设备可以通过至少一个第一中继之后，再连接到第二中继接入网络。第一中继可以是充当中继的终端设备，充当第一中继的多个终端设备和终端设备都有可能需要通过蜂窝网进行独立的通信，对第一中继和终端设备进行提供独立的UPF网元，从而能进一步对通信数据进行统计。本公开节点对应的UPF网元对接收到的用户面数据进行通信统计，通信统计方便，且每个节点产生的通信数据单独统计，统计精度高。
