Description

参数配置方法、装置、系统、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，特别涉及一种参数配置方法、装置、系统、设备及存储介质。
背景技术
3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)在R13(Release 13，第13版本)ProSe(Proximity Service，近距离通讯服务)架构中引入了中继通信这一概念。
中继通信是指基于IP(Internet Protocol，互联网协议)层中继的UE(User Equipment，终端设备)-to-Network(终端设备连接至网络)。也即，Remote UE(远程终端设备)通过Relay UE(中继终端设备)接入网络。其中，Relay UE承担IP层中继的功能，在Remote UE和网络之间传输数据，以建立Remote UE与网络之间的通信连接。为了保障业务传输质量，相关技术引入了服务质量(Quality of Service，QoS)架构，支持不同业务对应于不同的QoS需求。针对非中继通信，终端设备直接与网络建立连接，网络可以按照不同的QoS参数规制终端设备与网络之间不同业务的传输。然而，针对中继通信，网络可以按照不同的QoS参数规制与网络直接连接的中继终端设备之间不同业务的传输，却无法规制远程终端设备与中继终端设备之间不同业务的传输，进而无法保障远程终端设备与中继终端设备之间的业务传输质量。
因此，针对中继通信，如何进行远程终端设备与中继终端设备之间的QoS参数的配置，还需要进一步地讨论和研究。

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。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例提供的技术方案可以应用于各种通信系统，例如：GSM(Global System of Mobile Communication，全球移动通讯)系统、CDMA(Code Division Multiple Access，码分多址)系统、WCDMA(Wideband Code Division Multiple Access，宽带码分多址)系统、GPRS(General Packet Radio Service，通 用分组无线业务)、LTE(Long Term Evolution，长期演进)系统、FDD(Frequency Division Duplex，LTE频分双工)系统、TDD(Time Division Duplex，LTE时分双工)系统、UMTS(Universal Mobile Telecommunication System，通用移动通信系统)、WiMAX(Worldwide Interoperability for Microwave Access，全球互联微波接入)通信系统、5GS(5th-Generation System，第五代移动通信系统)或新空口(New Radio，NR)系统、或者后续其它的演进系统等。
请参考图1，其示出了本申请实施例提供的一种通信系统的系统架构的示意图。如图1所示，该系统架构100可以包括：终端设备10、接入网设备20和核心网设备30。
终端设备10可以指UE、接入终端、用户单元、用户站、移动站、移动台、远方站、远端终端、移动设备、无线通信设备、用户代理或用户装置。可选地，终端设备还可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol，会话启动协议)电话、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digita1Assistant，个人数字处理)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5GS中的终端设备或者未来演进的PLMN(Pub1ic Land Mobi1e Network，公用陆地移动通信网络)中的终端设备等，本申请实施例对此并不限定。
接入网设备20是一种部署在接入网中用以为终端设备提供无线通信功能的设备。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5GS中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备提供无线通信功能的装置统称为接入网设备。
核心网设备30是指可以为终端设备提供会话管理、移动性关系、策略管理、安全认证等功能的设备。本申请实施例中，核心网设备30可以包括第一核心网设备、第二核心网设备和第三核心网设备，其中，第一核心网设备负责终端设备的会话管理；第二核心网设备负责根据第一核心网设备的路由规则执行用户数据包转发；第三核心网设备负责用户策略管理。示例性地，在5GS系统中，第一核心网可以实现为SMF(Session Management Function，会话管理功能)，第二核心网设备可以实现为UPF(User Plane Function，用户面功能)，第三核心网设备可以实现为PCF(Policy Control Function，策略控制功能)。
在一个示例中，如图1所示，终端设备包括远程(Remote)终端设备12和中继(Relay)终端设备14。中继终端设备14可以与远程终端设备12之间进行数据传输，以建立远程终端设备12与网络设备之间的通信连接，该网络设备包括接入网设备20和/或核心网设备30。
图2示出了本申请实施例提供的5GS的系统架构的示意图。如图2所示，该系统架构200可以包括：UE、(R)AN((Radio)Access Network，(无线)接入网)、Core(核心网)和DN(Data Network，数据网络)构成。其中，UE、AN、Core是构成架构的主要成分，逻辑上它们可以分为用户面和控制面两部分，控制面负责移动网络的管理，用户面负责业务数据的传输。图2中，NG2参考点位于RAN控制面和Core控制面之间，NG3参考点位于RAN用户面和Core用户面之间，NG6参考点位于Core用户面和数据网络之间。其中：
UE：是移动用户与网络交互的入口，能够提供基本的计算能力、存储能力，向用户显示业务窗口，接受用户操作输入。UE会采用下一代空口技术，与RAN建立信号连接、数据连接，从而传输控制信号和业务数据到移动网络。
(R)AN：类似于传统网络里面的基站，部署在靠近UE的位置，为特定区域的授权用户提供入网功能，并能够根据用户的级别，业务的需求等使用不同质量的传输隧道传输用户数据。RAN能够管理自身的资源，合理利用，按需为UE提供接入服务，把控制信号和用户数据在UE和核心网之间转发。
Core：负责维护移动网络的签约数据，管理移动网络的网元，为UE提供会话管理、移动性管理、策略管理、安全认证等功能。在UE附着的时候，为UE提供入网认证；在UE有业务请求时，为UE分配网络资源；在UE移动的时候，为UE更新网络资源；在UE空闲的时候，为UE提供快恢复机制：在UE去附着的时候，为UE释放网络资源；在UE有业务数据时，为UE提供数据路由功能，如转发上行数据到DN：或者从DN接收UE下行数据，转发到RAN，从而发送给UE。
DN：是为用户提供业务服务的数据网络，一般客户端位于UE，服务端位于数据网络。数据网络可以是私有网络，如局域网，也可以是不受运营商管控的外部网络，如Internet，还可以是运营商共同部署的专有网络，如为了配置IMS(IP Multimedia Core Network Subsystem，IP多媒体网络子系统)服务。
图3是在图2的基础上确定的详细架构，其中核心网用户面包括UPF；核心网控制面包括AUSF(Authentication Server Function，认证服务器功能)、AMF(Core Access and Mobility Management Function，核心网接入和移动性管理功能)、SMF、UDM(Unified Data Management，统一数据管理)、PCF，AF(Application Function，应用功能)。这些功能实体的功能如下：
UPF：根据SMF的路由规则执行用户数据包转发；
AUSF：执行UE的安全认证；
AMF：UE接入管理和移动性管理；
SMF：UE会话管理；
UDM：用户签约上下文管理；
PCF：用户策略管理；
AF：用户应用管理。
在图3所示架构中，Uu接口为UE与AN之间的参考点，用于交互接入层消息及无线数据传输；N1接口为UE与AMF之间的参考点；N2接口为RAN和AMF的参考点，用于NAS消息的发送等；N3接口为RAN和UPF之间的参考点，用于传输用户面的数据等；N4接口为SMF和UPF之间的参考点，用于传输例如N3连接的隧道标识信息、数据缓存指示信息，以及下行数据通知消息等信息；N6接口为UPF和DN之间的参考点，用于传输用户面的数据等。
需要说明的是，图2和图3中的各个网元之间的接口名称只是一个示例，具体实现中接口的名称可能为其他的名称，本申请实施例对此不作具体限定。图2和图3中包括的各个网元(比如SMF、AF、UPF等)的名称也仅是一个示例，对网元本身的功能不构成限定。在5GS以及未来其它的网络中，上述各个网元也可以是其他的名称，本申请实施例对此不作具体限定。例如，在6G网络中，上述各个网元中的部分或全部可以沿用5G中的术语，也可能采用其他名称，等等，在此进行统一说明，以下不再赘述。此外，应理解，上述各个网元之间的所传输的消息(或信令)的名称也仅仅是一个示例，对消息本身的功能不构成任何限定。
终端设备接入网络之后，位于核心网的SMF通过控制信令将QoS规则发送给终端设备，终端设备使用QoS规则对上行业务数据进行匹配，将上行业务数据映射到合适的QoS流进行QoS控制。5G网络中考虑对多种新业务的支持，可能导致向终端设备配置的QoS参数构造复杂、更新频繁等，为此5G网络中引入了可选的反向映射QoS参数机制。该反向映射QoS参数机制的主要思想是在下行数据包头添加QoS流的标识QFI以及反向映射指示，终端设备根据收到的下行数据包自行确定QoS规则，用于上行数据的传输，从而减少了SMF和终端设备的信令交互。
本申请实施例中，当一个终端设备既具有通过5G等网络连接外部数据网络的能力，还具有ProSe(Proximity-based Services，近距离业务)能力时，这个终端设备可以充当中继终端设备，另外一个具有ProSe能力的终端设备作为远程终端设备。具有Prose能力的终端设备可以通过PC5接口与另一个具有Prose能力的终端设备直接通信。如图4所示，远程终端设备可以通过PC5接口与中继终端设备建立直接连接，并通过中继终端设备与网络建立的PDU会话与外部网络交互。
在一个示例中，核心网通过控制平面消息向中继终端设备发送中继终端设备与远程终端设备之间的QoS参数(也称为PC5QoS参数)，或者向中继终端设备发送网络设备与中继终端设备之间的QoS参数(也称为Uu QoS参数)，该网络设备包括核心网设备和/或接入网设备。从而，在中继终端设备接收到中继终端设备与远程终端设备之间的QoS参数时，可以直接使用该QoS参数规制与远程终端设备之间的业务传输；在中继终端设备接收到网络设备与中继终端设备之间的QoS参数时，可以根据网络设备与中继终端设备之间的QoS参数进一步确定中继终端设备与远程终端设备之间的QoS参数，后续使用确定得到的QoS参数规制与远程终端设备之间的业务传输。
然而，针对中继通信，若核心网中的SMF启动反向映射QoS参数机制，则中继终端设备不再与SMF进行信令交互，从而中继终端设备也无法获取QoS参数。因此，尽管核心网中的UPF向中继终端设备发送的下行数据包的包头中携带QFI，中继终端设备也无法确定与该QFI对应的QoS参数，进而无法保障远程终端设备与中继终端设备之间的业务传输质量。
基于此，本申请实施例提供了一种参数配置方法，通过在核心网确定启动反向映射QoS参数机制的情况下，向中继终端设备发送参数配置信息，该参数配置信息即用于配置中继终端设备与远程终端设备之间的QoS参数。在本申请实施例中，核心网既可以通过控制平面消息将参数配置信息发送给中继终端设备，也可以通过用户平面消息将参数配置信息发送给中继终端设备，并且，在采用不同的发送方式时，参数配置信息的内容也可能会有所区别。
下面，通过几个实施例对本申请的技术方案进行介绍说明。
请参考图5，其示出了本申请一个实施例提供的参数配置方法的流程图，该方法可以应用于上述图1或图4所示的通信系统中。该方法可以包括如下几个步骤：
步骤510，核心网向中继终端设备发送参数配置信息，其中，参数配置信息用于在启动反向映射QoS参数机制的情况下，配置中继终端设备与远程终端设备之间的QoS参数。
中继终端设备与远程终端设备之间的QoS参数，又可以称为PC5QoS参数，用于保障中继终端设备与远程终端设备之间的业务传输质量。本申请实施例中，核心网在确定需要启动反向映射QoS参数机制的情况下，向中继终端设备发送参数配置信息，以配置中继终端设备与远程终端设备之间的QoS参数。
本申请实施例对核心网向中继终端设备发送参数配置信息的时机和方式不作限定。在一个示例中，核心网在确定启动反向映射QoS机制，且启动反向映射QoS参数机制之前，向中继终端设备发送参数配置信息，从而该参数配置信息是核心网通过控制平面消息发送给中继终端设备的，也即，核心网中的控制平面功能实体向中继终端设备发送参数配置信息。在另一个示例中，核心网在确定启动反向映射QoS机制，且启动反向映射QoS参数机制的过程中或启动反向映射QoS参数机制之后，向中继终端设备发送参数配置信息，从而该参数配置信息是核心网通过用户平面消息发送给中继终端设备的，也即，核心网中的用户平面功能实体向中继终端设备发送参数配置信息。
由上述介绍说明可知，针对核心网在不同时机向中继终端设备发送参数配置信息，该参数配置信息的发送实体有所区别。作为一个示例，在某一时机下，参数配置信息的发送实体与已有的信息交互架构中对应于该时机下与中继终端设备交互的核心网功能实体相吻合。
例如，在已有的信息交互架构中，启动反向映射QoS参数机制之前由核心网中的控制平面功能实体与中继终端设备之间进行交互，从而，在启动反向映射QoS参数机制之前，由控制平面功能实体作为参数配置信息的发送实体。又例如，在已有的信息交互架构中，启动反向映射QoS参数机制的过程中或之后，由核心网中的用户平面功能实体与中继终端设备之间进行交互，从而，在启动反向映射QoS参数机制的过程中或之后，由用户平面功能实体作为参数配置信息的发送实体。
通过在不同时机下，设置与已有的信息交互架构相吻合的参数配置信息的发送实体，能够避免对已有的信息交互架构进行过多地、繁琐地修改，提升了启动反向映射QoS参数时QoS参数配置的兼容性，另外，也避免了中继终端设备同时与过多不同的功能实体进行信息交互，有助于提升QoS参数配置的效率。
可选地，由核心网中不同的功能实体向中继终端设备发送的参数配置信息的内容可能有所不同。示例性地，由控制平面功能实体向中继终端设备发送的参数配置信息包括QoS参数，而由用户平面功能实体向中继终端设备发送的参数配置信息包括QFI。尽管参数配置信息的内容有所不同，但在本申请实施例中，中继终端设备根据接收到的参数配置信息均可以确定中继终端设备与远程终端设备之间的QoS参数。有关参数配置信息的内容，以及中继终端设备如何确定QoS参数等的介绍说明，请参见下述实施例，此处不多赘述。
综上所述，本申请实施例提供的技术方案，通过在核心网确定启动反向映射QoS参数机制的情况下，由核心网向中继终端设备发送参数配置信息，以配置中继终端设备和远程终端设备之间的QoS参数，解决了中继通信系统中核心网在启动反向映射QoS参数的情况下，中继终端设备无法获取QoS参数的缺陷，保障了中继终端设备与远程终端设备之间的业务传输质量。另外，在本申请实施例中，并不限定由核心网中的哪一个功能实体向中继终端设备发送参数配置信息，从而在实际应用过程中，可以根据已知的信息交互架构，灵活设置参数配置信息的发送实体，一方面吻合已知的信息交互架构，提升了参数配置的兼容性和效率，另一方面，提升了参数配置的灵活性。
在一个示例中，参数配置信息包括PCC规则所绑定的QFI，以及QFI对应的QoS参数。
PCC(Policy and Charging Control，策略与计费控制)规则是与用户策略管理相关的规则，其中，PCC规则针对QoS流相关的要求进行了规定。由上述介绍说明可知，在启动反向映射QoS参数机制的过程中或之后，中继终端设备是根据下行数据包的包头所携带的QFI和反向映射指示，来确定与远程终端设备之间的QoS参数，因此，可以建立QFI与QoS参数之间的对应关系，以便于后续中继终端设备根据下行数据包的包头所携带的QFI确定对应的QoS参数。
基于此，核心网向中继终端设备发送的参数配置信息包括PCC规则所绑定的QFI，以及QFI对应的QoS参数。可选地，QFI对应的QoS参数包括以下至少一项：中继终端设备与远程终端设备之间的QoS参数、中继终端设备与网络设备之间的QoS参数。其中，本申请实施例对网络设备的类型不作限定，该网络设备可以为接入网设备，如基站等；也可以为核心网设备，如UPF等。
由于QoS参数由核心网中的控制平面功能实体配置，因此，在参数配置信息包括QoS参数的情况下，可以由控制平面功能实体向中继终端设备发送参数配置信息。可选地，核心网包括第一核心网设备，第一核心网设备用于提供控制平面功能，也即，第一核心网设备为控制平面功能实体。例如，第一核心网设备实现为上述实施例中介绍的SMF。因此，参数配置信息承载在第一核心网设备与中继终端设备交互的控制平面消息中。
本申请实施例中，参数配置信息中的QoS参数是与PCC规则所绑定的QFI相对应的，因而第一核心网设备需要确定PCC规则所绑定的QFI。基于此，上述核心网还包括第三核心网设备，第三核心网设备用于提供控制平面功能，也即，第三核心网设备也为控制平面功能实体。例如，第三核心网设备实现为上述实施例中介绍的PCF。如图6所示，上述步骤510包括如下几个步骤：
步骤512，第三核心网设备向第一核心网设备发送PCC规则，PCC规则包括第一映射指示信息，第一映射指示信息用于指示是否启动反向映射QoS参数机制。
第三核心网设备用于用户策略管理，因而，由第三核心网设备生成PCC规则。第三核心网设备在生成PCC规则后，可以将该PCC规则发送给第一核心网设备。可选地，第三核心网设备还可以确定是否启动反向映射QoS参数机制，并将确定结果告知第一核心网设备。为了减少第三核心网设备与第一核心网设备之间的信令往来，第三核心网设备可以在PCC规则中携带第一映射指示信息，以向第一核心网设备指示是否启动反向映射QoS参数机制。
步骤514，第一核心网设备确定PCC规则对应的配置的状态。
第一核心网设备接收到PCC规则后，可以确定PCC规则所绑定的QoS流，进而将该QoS流标识QFI确定为PCC规则所绑定的QFI，然后根据PCC规则所绑定的QFI来配置参数配置信息。
此外，由于本申请实施例是在中继通信过程中，向中继终端设备发送参数配置信息，因此，第一核心网设备还需要确定PCC规则对应的配置是否为中继状态。若PCC规则对应的配置处于非中继状态，则第一核心网设备无需为终端设备配置参数配置信息。可选地，PCC规则对应的配置包括以下至少一项：PCC规则对应的终端设备、PCC规则对应的PDU(Protocol Data Unit，协议数据单元)会话、PCC规则对应的SDF(Service Data Flow，业务数据流)。
步骤516，第一核心网设备在第一映射指示信息用于指示启动反向映射QoS参数机制，且PCC规则对应的配置处于中继状态的情况下，向中继终端设备发送参数配置信息。
在第一映射指示信息用于指示启动反向映射QoS参数机制，并且PCC规则对应的配置处于中继状态的情况下，第一核心网设备确定需要为中继终端设备配置参数配置信息。第一核心网设备在根据PCC规则所绑定的QFI确定了参数配置信息后，在启动反向映射QoS参数机制之前，向中继终端设备发送参数配置信息。
反向映射QoS参数机制启动过程中或启动之后，核心网中的控制平面功能实体不再与中继终端设备进行信令往来，而由核心网中的用户平面功能实体与中继终端设备进行信令往来。因此，本申请实施例中，核心网还包括第二核心网设备，第二核心网设备用于提供用户平面功能，也即，第二核心网设备为用户平面功能实体。例如，第二核心网设备为上述实施例中介绍的UPF。基于此，如图6所示，上述方法还包括如下几个步骤：
步骤522，第二核心网设备向中继终端设备发送下行数据包。
第二核心网设备可以中继终端设备发送下行数据包，该下行数据包携带QFI，可选地，由下行数据包的包头携带QFI。
步骤524，中继终端设备确定下行数据包所携带的QFI。
中继终端设备接收到下行数据包之后，可以解析该下行数据包，以获取下行数据包所携带的QFI。
步骤526，中继终端设备基于参数配置信息和下行数据包所携带的QFI，确定中继终端设备与远程终端设备之间的QoS参数。
一方面，中继终端设备根据第一核心网设备发送的参数配置信息，明确了QFI和QoS参数之间的对应关系；另一方面，中继终端设备根据第二核心网设备发送的下行数据包解析出QFI，从而，中继终端设备按照QFI和QoS参数之间的对应关系，即可确定与下行业务数据包所携带的QFI对应的QoS参数，进而确定中继终端设备与远程终端设备之间的QoS参数。
由上述介绍可知，第一核心网设备发送的参数配置信息中，与QFI对应的QoS参数可能是中继终端设备与远程终端设备之间的QoS参数，也可能是中继终端设备与网络设备之间的QoS参数。针对QFI对应的QoS参数包括中继终端设备与远程终端设备之间的QoS参数，中继终端设备直接确定与远程终端设备之间的QoS参数，也即，上述步骤526，包括：中继终端设备将下行数据包的包头所携带的QFI对应的QoS参数，作为中继终端设备与远程终端设备之间的QoS参数。针对QFI对应的QoS参数包括中继终端设备与网络设备之间的QoS参数，中继终端设备间接确定与远程终端设备之间的QoS参数，也即，上述步骤526，包括：中继终端设备将下行数据包的包头所携带的QFI对应的QoS参数，作为中继终端设备与网络设备之间的QoS参数；基于中继终端设备与网络设备之间的QoS参数，确定中继终端设备与远程终端设备之间的QoS参数。
综上所述，本申请实施例提供的技术方案，通过在核心网启动反向映射QoS参数机制之前，由核心网中的控制平面功能实体向中继终端设备发送参数配置信息，该参数配置信息包括QFI以及与QFI对应的QoS参数，从而后续中继终端设备可以根据接收到的下行数据包所携带的QFI，来确定与远程终端设备之间的QoS参数，有效保障了中继终端设备与远程终端设备之间的业务传输质量。
在一个示例中，参数配置信息包括PCC规则所绑定的QFI；其中，PCC规则所绑定的QFI等于系统QoS标识。
系统QoS标识是终端设备与网络设备之间的QoS参数中最重要的部分，通常情况下，明确了系统QoS标识，也就明确了终端设备与网络设备之间的QoS参数。另外，针对中继通信而言，中继终端设备与网络 设备之间的QoS参数，可以和中继终端设备与远程终端设备之间的QoS参数之间建立对应关系等，从而，中继终端设备明确了中继终端设备与网络设备之间的QoS参数，也就可以进一步明确中继终端设备与远程终端设备之间的QoS参数。因此，若PCC规则所绑定的QFI等于系统QoS标识，那么，中继终端设备明确了PCC规则所绑定的QFI，也就明确了中继终端设备与网络设备之间的QoS参数，从而可以进一步明确中继终端设备与远程终端设备之间的QoS参数。
基于此，在PCC规则所绑定的QFI等于系统QoS标识的情况下，核心网向中继终端设备发送的参数配置信息包括PCC规则所绑定的QFI。可选地，系统QoS标识包括5QI(5G QoS Identifier，第五代移动通信系统QoS标识)。
由于在启动反向映射QoS参数机制之后，核心网与中继终端设备之间交互的为用户平面消息，且该消息中携带QFI。基于此，核心网包括第二核心网设备，第二核心网设备用于提供用户平面功能，也即，第二核心网设备为用户平面功能实体。例如，第二核心网设备为上述实施例中介绍的UPF。因此，参数配置信息承载在第二核心网设备与中继终端设备交互的用户平面消息中。可选地，用户平面消息包括下行数据包，参数配置信息承载在下行数据包的包头中。
本申请实施例中，PCC规则所绑定的QFI是由核心网中的控制平面功能实体向用户平面功能实体发送的。基于此，核心网还包括第一核心网设备和第三核心网设备，第一核心网设备和第三核心网设备用于提供控制平面功能，也即，第一核心网设备和第三核心网设备为控制平面功能实体。例如，第一核心网设备为上述实施例中介绍的SMF，第三核心网设备为上述实施例中介绍的PCF。
另外，在本申请实施例中，既可以由第一核心网设备确定是否需要启动反向映射QoS参数机制，也可以由第三核心网设备确定是否需要启动反向映射QoS参数机制。下面，分别针对这两种情况进行介绍说明。
在一个示例中，如图7所示，上述步骤510包括如下几个步骤：
步骤51A，第三核心网设备向第一核心网设备发送PCC规则，PCC规则包括第一映射指示信息，第一映射指示信息用于指示是否启动反向映射QoS参数机制。
有关步骤51A的介绍说明，请参见上述步骤512的介绍说明，此处不多赘述。
步骤51C，第一核心网设备在第一映射指示信息用于指示启动反向映射QoS参数机制、PCC规则对应的配置处于中继状态、以及PCC规则所绑定的QFI能够等于系统QoS标识的情况下，向第二核心网设备发送第二映射指示信息以及PCC规则所绑定的QFI，第二映射指示信息用于指示启动反向映射QoS参数机制。
本申请实施例中，第一核心网设备在接收到PCC规则之后，确定是否启动反向映射QoS参数机制。由上述介绍说明可知，在PCC规则所绑定的QFI等于系统QoS标识的情况下，中继终端设备可以根据PCC规则所绑定的QFI来确定QoS参数。因此，第一核心网设备可以根据PCC规则所绑定的QFI是否能够等于系统QoS参数，来确定是否启动反向映射QoS参数机制。
此外，正如上述步骤514的介绍说明，由于本申请实施例是在中继通信过程中，向中继终端设备发送参数配置信息，因此，第一核心网设备还可以确定PCC规则对应的配置是否为中继状态。若PCC规则对应的配置处于非中继状态，则第一核心网设备无需为终端设备配置参数配置信息。可选地，PCC规则对应的配置包括以下至少一项：PCC规则对应的终端设备、PCC规则对应的PDU会话、PCC规则对应的SDF。
基于此，在第一核心网设备接收到的第一映射信息用于指示启动反向映射QoS参数机制、PCC规则对应的配置处于中继状态、PCC规则所绑定的QFI能够等于系统QoS标识这三个条件同时满足的情况下，第一核心网设备确定启动反向映射QoS参数机制，并向第二核心网设备发送第二映射指示信息以及PCC规则所绑定的QFI，以告知第二核心网设备启动反向映射QoS参数机制。此外，本申请实施例中，在上述三个条件不同时满足的情况下，第一核心网设备确定不启动反向映射QoS参数机制。
步骤51E，第二核心网设备向中继终端设备发送参数配置信息。
第二核心网设备接收到第二映射指示信息以及PCC规则所绑定的QFI，确定启动反向映射QoS参数机制时，根据PCC规则所绑定的QFI确定参数配置信息。可选地，第二核心网设备将PCC规则所绑定的QFI设置在下行数据包的包头中，也即，参数配置信息承载在下行数据包的包头中。从而，中继终端设备在接收到下行数据包之后，即可解析得到PCC规则所绑定的QFI。
正是由于PCC规则所绑定的QFI等于系统QoS标识这一条件能够成立，中继终端设备才可以依据PCC规则所绑定的QFI明确中继终端设备与远程终端设备之间的QoS参数，因此，第一核心网设备还需要将PCC规则所绑定的QFI设置为系统QoS标识。基于此，可选地，如图7所示，上述方法还包括：第一核心网设备在PCC规则对应的配置处于中继状态，且PCC规则所绑定的QFI能够等于系统QoS标识的情况下，将PCC规则所绑定的QFI设置为系统QoS标识。
在另一个示例中，如图7所示，上述步骤510包括如下几个步骤：
步骤51B，第三核心网设备在PCC规则对应的配置处于中继状态，且PCC规则所绑定的QFI能够等于系统QoS标识的情况下，向第一核心网设备发送PCC规则，PCC规则包括第一映射指示信息，第一映 射指示信息用于指示启动反向映射QoS参数机制。
由上述介绍说明可知，在PCC规则所绑定的QFI等于系统QoS标识的情况下，中继终端设备可以根据PCC规则所绑定的QFI来确定QoS参数。因此，第三核心网设备可以根据PCC规则所绑定的QFI是否能够等于系统QoS参数，来确定是否启动反向映射QoS参数机制。此外，正如上述步骤514的介绍说明，由于本申请实施例是在中继通信过程中，向中继终端设备发送参数配置信息，因此，第三核心网设备还可以确定PCC规则对应的配置是否为中继状态。若PCC规则对应的配置处于非中继状态，则第三核心网设备无需确定PCC规则所绑定的QFI是否能够等于系统QoS标识。可选地，PCC规则对应的配置包括以下至少一项：PCC规则对应的终端设备、PCC规则对应的PDU会话、PCC规则对应的SDF。
基于此，在第三核心网设备确定PCC规则对应的配置处于中继状态、PCC规则所绑定的QFI能够等于系统QoS标识这两个条件同时满足的情况下，第三核心网设备确定启动反向映射QoS参数机制，并向第一核心网设备发送第一映射指示信息，以告知第一核心网设备启动反向映射QoS参数机制。此外，本申请实施例中，在第三核心网设备确定PCC规则对应的配置处于中继状态，且PCC规则所绑定的QFI无法等于系统QoS标识的情况下，第一核心网设备确定不启动反向映射QoS参数机制。
步骤51D，第一核心网设备向第二核心网设备发送第二映射指示信息以及PCC规则所绑定的QFI，第二映射指示信息用于指示启动反向映射QoS参数机制。
第一核心网设备接收到第一映射指示信息，明确启动反向映射QoS参数机制的情况下，向第二核心网设备发送第二映射指示信息以及PCC规则所绑定的QFI，以告知第二核心网设备启动反向映射QoS参数机制。
步骤51F，第二核心网设备向中继终端设备发送参数配置信息。
有关步骤51F的介绍说明，请参见上述步骤51E的介绍说明，此处不多赘述。
由上述介绍说明可知，第一核心网设备还需要将PCC规则所绑定的QFI设置为系统QoS标识。本申请实施例中，既可以由第一核心网设备自行确定是否需要将PCC规则所绑定的QFI设置为系统QoS标识，也可以由第三核心网设备告知第一核心网设备是否需要将PCC规则所绑定的QFI设置为系统QoS标识。基于此，在一个示例中，如图7所示，上述方法还包括：第三核心网设备在PCC规则对应的配置处于中继状态，且PCC规则所绑定的QFI能够等于系统QoS标识的情况下，向第一核心网设备发送标识设置指示信息；第一核心网设备按照第一标识指示信息，将PCC规则所绑定的QFI设置为系统QoS标识。可选地，标识设置指示信息可以承载于PCC规则中，也可以独立于PCC规则，本申请实施例对此不作限定。在另一个示例中，如图7所示，上述方法还包括：第一核心网设备在PCC规则对应的配置处于中继状态的情况下，将PCC规则所绑定的QFI设置为系统QoS标识。
中继终端设备在明确了参数配置信息，即PCC规则所绑定的QFI之后，即可根据该QFI来确定中继终端设备与远程终端设备之间的QoS参数。基于此，如图7所示，上述方法还包括如下几个步骤：步骤532，中继终端设备基于参数配置信息，确定中继终端设备与网络设备之间的QoS参数。步骤534，中继终端设备基于中继终端设备与网络设备之间的QoS参数，确定中继终端设备与远程终端设备之间的QoS参数。
综上所述，本申请实施例提供的技术方案，通过在核心网启动反向映射QoS参数机制的过程中或之后，由核心网中的用户平面功能实体向中继终端设备发送参数配置信息，该参数配置信息包括QFI，且该QFI等于系统QoS标识。由于中继终端设备明确了系统QoS标识，也就明确了与网络设备之间的QoS参数，并进一步根据与网络设备之间的QoS参数明确与远程终端设备之间的QoS参数。从而，中继终端设备可以根据等于系统QoS标识的QFI，来确定与远程终端设备之间的QoS参数，有效保障了中继终端设备与远程终端设备之间的业务传输质量。
下面，以几个示例性实施例对本申请的技术方案进行介绍说明。假设第一核心网设备为SMF、第二核心网设备为UPF、第三核心网设备为PCF、系统QoS标识为5QI等。
