Description

管理QoS的方法、中继终端、PCF网元、SMF网元及远程终端 技术领域
本申请涉及通信技术领域，尤其涉及一种管理QoS的方法、中继终端、PCF网元、SMF网元及远程终端。
背景技术
设备到设备(Device-to-Device，简称D2D)通信允许用户设备(User Equipment，简称UE)之间直接进行通信，有效的提高频谱资源的利用率。当UE处于网络覆盖之外或其与无线接入网络(Radio Access Network，简称RAN)间通信信号不好时，远程终端(例如，Remote UE)可以通过中继终端(例如，Relay UE)进行辅助，例如，通过远程终端与中继终端间的通信，以及中继终端与网络侧设备的之间通信，以实现远程终端与网络侧设备之间的通信。
在***移动通信技术(the 4th generation mobile communication technology，4G)***的非直接通信中，远程终端和中继终端之间数据传输的服务质量(Quality of Service，QoS)处理是基于数据包优先级(ProSe Per-Packet Priority，PPPP)和数据包可靠度(ProSe Per-Packet Reliability，PPPR)进行的，中继终端和网络侧设备之间数据传输的QoS处理是基于承载(bear)进行的。在第五代移动通信技术(the 5th generation mobile communication technology，5G)***的非直接通信中，远程终端和中继终端之间数据传输(可以称之为第一段数据传输)，以及中继终端和网络侧设备之间数据传输(可以称之为第二段数据传输)都是基于QoS流(flow)粒度进行QoS管理的，且第一段数据传输与第二段数据传输的QoS管理是分别独立进行的，二者之前可能会存在一些QoS参数(如传输速率相关的QoS参数)不匹配，无法满足远程终端到网络侧业务传输的需求。
发明内容
本申请实施例所要解决的技术问题在于，提供一种管理QoS的方法、中继终端、PCF网元、SMF网元及远程终端，以合理的管理远程终端到网络侧的QoS，保障远程终端到网络侧的业务传输需求。
第一方面，本申请的实施例提供了一种管理服务质量的方法，可包括：
中继终端从网络设备获取QoS信息，所述QoS信息包括第一QoS信息和/或第二QoS信息，所述第一QoS信息用于在远程终端与所述中继终端之间传输所述远程终端的数据，所述第二QoS信息用于在所述中继终端与用户面功能UPF网元之间传输所述远程终端的数据；
所述中继终端根据所述QoS信息，向所述远程终端发送所述第一QoS信息。
由于第一QoS信息用于传输远程终端的数据，且存在第二QoS信息时，第二QoS信息也用于传输该远程终端的数据。二者在一些QoS参数上具备相互映射的关系，因此第一QoS信息和第二QoS信息也就具备了相互关联的关系，二者在传输速率和传输时延上均考虑到了远程终端到网络侧进行中继传输的业务传输需求，因此可以为远程终端提供端到端的QoS传输保障。例如，从时延角度考虑，按照现有机制传输，远程终端到中继终端和中继终端 到网络侧两段的时延可能大于远程终端的业务时延需求，这时候可以通过本申请中相互关联的第一QoS信息和第二QoS信息的配合来控制端对端的传输时延；从速率角度考虑，如果远程终端到中继终端和中继终端到网络侧两段的速率不一致，会导致在中继终端处数据丢包，因此在本申请中，可以通过将第一QoS信息和第一QoS信息中的速率参数保持一致来控制丢包率。从而充分满足远程终端到UPF网元的中继传输需求。
在一种可能的实现方式中，所述QoS信息包括所述第二QoS信息，且所述QoS信息不包括所述第一QoS信息，所述中继终端根据所述QoS信息，向所述远程终端发送所述第一QoS信息，包括：
所述中继终端根据所述第二QoS信息确定所述第一QoS信息，并向所述远程终端发送所述第一QoS信息。
当中继终端只接收到第二QoS信息时，可以根据第二QoS信息中的QoS参数来生成第一QoS信息，并使得二者在一些QoS参数上具备映射关系，从而使得远程终端到中继终端，以及中继终端到网络侧的QoS管理能够相互关联，确保远程终端的中继传输需求。
在一种可能的实现方式中，所述中继终端获取QoS信息，包括：
所述中继终端接收来自会话管理功能SMF网元或PCF网元的所述QoS信息。
在一种可能的实现方式中，所述方法还包括：
所述中继终端接收来自所述远程终端的中继通信指示信息，所述中继通信指示信息用于指示所述远程终端进行中继通信；
当网络侧的设备接收到中继通信指示信息时，便可以获知到此次传输为中继传输。因此，中继通信指示信息可以直接指示该PDU会话为远程终端的中继传输服务。
所述中继终端根据所述中继通信指示信息，向SMF网元发送所述远程终端的第一标识信息。
第一标识信息可以是远程终端的IP地址或ID，当网络侧的设备接收到中继终端上报的非中继终端的标识，或者接收到中继终端上报的两个终端的标识时，便可以获知到此次传输为中继传输。因此，远程终端的第一标识信息可以用于隐含指示该PDU会话为远程终端的中继传输服务。
在一种可能的实现方式中，还包括：
所述中继终端向SMF网元发送所述远程终端的第二标识信息。

此外，上述***架构还可以包括应用功能(application function，简称AF)网元100。
其中，AF网元100，主要用于向5G网络提供业务QoS策略需求和路由策略需求等。
具体地，以上行传输为例，在图1所示的架构中，远程终端10可以通过中继终端20接入到网络(例如，RAN设备30)，实现远程终端与网络之前进行非直接通信。远程终端10的数据传输可以经过两段路径：远程终端10到中继终端20，和中继终端20到UPF网元70。远程终端10到中继终端20的数据传输QoS处理可以基于PC5 QoS模型，中继终端20 到UPF网元70的数据传输QoS处理可以基于5G QoS模型。
其中，5G QoS模型可以指的是5G***中的基于QoS流(flow)来管理和配置QoS的模型，5G QoS模型支持保障比特速率(guaranteed bit rate，简称GBR)的QoS流(GBR QoS Flow)和非保障比特速率的QoS流(Non-GBR QoS Flow)，5G QoS模型还支持反射QoS。
QoS流是PDU会话中的QoS区分粒度。在5G***中，QoS流可以通过服务质量流的标识(qos flow identity,简称QFI)来标识，PDU会话中具有相同QFI的用户面数据可以获得相同的转发处理(如相同的调度、相同的准入门限等)。
QoS流的内容可以包括：
为RAN配置的QoS配置文件(QoS Profile)，该配置文件可以是SMF网元通过AMF网元提供给RAN设备，或者预先设置在RAN设备上，不予限制。
为终端设备配置的QoS规则(rule)，该规则可以是SMF网元在PDU会话建立或修改的过程中提供给该终端设备的，或该终端设备通过反射QoS机制推导出来的。
一个QoS流的资源类型为GBR QoS flow还是Non-GBR QoS flow，具体可以根据QoS配置文件来确定。例如，GBR QoS流的QoS配置文件通常包含以下QoS参数：5G QoS指示符(5G QoS identifier,简称5QI)、分配保持优先级(allocation and retention priority,简称ARP)、保证流比特速率(guaranteed flow bit rate,简称GFBR)和最大流比特速率(maximum flow bit rate,简称MFBR)。而Non-GBR QoS流的QoS配置文件通常不包含GFBR和MFBR。
可选的，QoS配置文件包含QoS通知控制(QoS notification control,简称QNC)；根据配置文件是否包含QNC将GBR QoS flow分为需要QNC的GRB QoS flow和不需要QNC的GBR QoS flow。
对于Non-GBR QoS flow，对应的QoS配置文件通常包含以下QoS参数：5QI、ARP；可选的包含反射QoS属性(reflective QoS attribute，简称RQA)。
5G QoS流模型中相关的QoS参数的相关定义如下：
5QI：用于索引到5G QoS特征值；5QI分为标准化的5QI、预配置的5QI和动态分配的5QI。对于标准化的5QI，与一组标准化的5G QoS特征值一一对应；对于预配置的5QI，对应的5G QoS特征值预配置在无线接入网设备；对于动态分配的5QI，对应的5G QoS特征值包含在QoS配置文件中发送给RAN。
5G QoS特征值：可以包括以下一项或多项：资源类型(resource type，简称RT)，例如，GBR或Non-GBR，优先级级别(priority level)，数据包时延预算(packet delay budget)，数据包错误概率(packet error rate)，最大数据突发量(maximum data burst volume)，或平均窗口(averaging window)。其中，平均窗口可以用于计算GBR对应的速率；数据包时延预算可以指的是数据包从UE到UPF的时延。
ARP：包含优先等级、抢占能力和被抢占能力；
RQA：用于指示当前QoS flow传输的业务是否使用反射QoS；
QNC：用于指示RAN当GBR QoS flow的GFBR不能满足时是否通知网络；
GFBR：用于指示保证提供给GBR QoS flow的比特率；
MFBR：用于指示限制提供给GBR QoS flow的比特率，即提供给GBR QoS flow的最大 比特率。
在基于5G***的D2D通信中，使用基于QoS flow的PC5 QoS模型，与5G QoS模型相似。两个终端设备之间可以建立一个或者多个链路(link)，每个link中可以建立一个或者多个QoS flow。每个QoS flow可以由一个PC5 QoS流标识(PC5 QoS Flow Identifier,简称PFI)来标识，PFI在链路中可以唯一标识一个QoS flow。PC5 QoS支持GBR QoS flow和Non-GBR QoS flow。PC5 QoS模型中相关的PC5 QoS参数包括PQI、PC5流比特速率(PC5 Flow Bit Rate)和PC5链路聚合比特速率(PC5 Link Aggregated Bit Rates)。PQI是一种特殊的5QI，每一个PQI值与QoS特征值一一对应，QoS特征值中包含内容与5G QoS模型中相同。PC5流比特速率包括Guaranteed Flow Bit Rate(GFBR)和Maximum Flow Bit Rate(MFBR)。
本申请各实施例可以应用于远程终端进行中继传输的场景中，例如，图1所示架构中远程终端10通过中继终端20与网络侧进行通信。此外，在申请各实施例中，对远程终端的端到端数据传输的QoS管理可以包括：配置远程终端到中继终端的QoS参数和中继终端到UPF网元的QoS参数，由于两部分的QoS参数都基于为远程终端进行中继传输来进行配置，从而可以保障远程终端的业务传输需求。
下面结合图2-图9对本申请管理QoS的方法进行详细描述。
请参见图2，图2为本申请实施例提供的一种管理QoS的方法的流程示意图；可包括如下步骤：
S201、中继终端从网络设备获取QoS信息。
具体地，中继终端可以接收来自会话管理功能SMF网元或PCF网元的该QoS信息。
可选地，QoS信息包括第一QoS信息和/或第二QoS信息。
其中，第一QoS信息可以用于在远程终端与该中继终端之间传输该远程终端的数据。
其中，第二QoS信息可以用于在该中继终端与UPF网元之间传输该远程终端的数据。
示例性地，第一QoS信息中可以包含远程终端到中继终端的QoS参数，可称为PC5 QoS参数。具体地，PC5 QoS参数可包括应用于PC5接口的5G QoS特征值中的全部或部分参数，或者包括应用于PC5口的5G QoS特征值对应的5QI。例如，PC5 QoS参数可以包括PC5 5QI(PQI)和PC5链路聚合最大比特速率(PC5 Link Aggregated Maximum Bit Rates，简称PC5 Link-AMBR)。
示例性地，第二QoS信息中可以包含中继终端到UPF网元的QoS参数，可包括5G QoS特征值中的全部或部分参数。或者，第二QoS信息可以包括5QI、ARP、或会话聚合最大比特速率(Session-aggregate maximum bit rate,简称Session-AMBR)。
可选地，在步骤S201之前，上述方法还包括如下步骤：
中继终端接收来自远程终端的中继通信指示信息。
相应地，中继终端根据所述中继通信指示信息，向SMF网元发送所述远程终端的第一标识信息。第一标识信息用于作为远程终端的标识，可以是远程终端的ID或IP地址。
其中，所述中继通信指示信息可以用于指示所述远程终端进行中继通信。
可选地，中继终端可以利用PDU会话建立请求消息或PDU会话修改请求消息发送第一标识信息，如远程终端的ID或IP地址。SMF网元接收到第一标识信息之后，确定当前传 输为远程终端的中继传输。SMF网元将远程终端的第一标识信息发送给PCF网元。PCF网元可以根据第一标识信息获取到与第一标识信息绑定的相关信息，该相关信息可以包括中继传输模式下远程终端的QoS参数等，进而PCF网元可以根据这些相关信息生成QoS信息，然后再下发给中继终端。
此外，中继终端还可以发送远程终端的第二标识信息，第二标识信息同样用于作为远程终端的标识，用于与第一标识信息进行区分，二者不同。如第二标识信息可以是远程终端的IP地址(则此时第一标识信息可以是远程终端的ID)，SMF网元将远程终端的第一标识信息和第二标识信息发送给PCF网元。假设第一标识信息为远程终端的ID，第二标识信息为远程终端的IP地址，PCF网元可以根据该ID和IP地址获取到与该ID和IP地址绑定的相关信息，如中继传输模式下远程终端的QoS参数等，进而PCF网元可以根据这些相关信息生成QoS信息，然后再下发给中继终端。
具体地，第一标识信息可以是远程终端的ID,例如,订阅永久标识(Subscr iption Permanent Identifier,简称SUPI),设备永久标识(Permanent Equipment Identifier,简称PEI),5G全球唯一临时标识(5G Globally Unique Temporary Identifier,简称5G-GUTI)或者通用公共订阅标识(Generic Public Subscription Identifier,简称GPSI)。
S202、中继终端根据QoS信息，向远程终端发送第一QoS信息。
需要说明的是，由于在步骤S201中中继终端获取到的QoS信息可以只包括第一QoS信息，或者只包括第二QoS信息，也可以同时包括第一QoS信息和第二QoS信息，因此下面分情况说明。
情况1，当步骤S201中获取的QoS信息只包括第二QoS信息时，可以由中继终端根据第二QoS信息生成第一QoS信息并发送给远程终端。
其中，中继终端根据第二QoS信息生成第一QoS信息时，可通过如下方式实现。
方式一、第二QoS信息中包括5QI，中继终端根据5QI确定第一QoS信息中PQI。5QI与PQI的对应关系预先配置在中继终端，或中继终端在注册时通过控制面从PCF获取，或中继终端通过数据面从ProSe Function获取。
方式二、第二QoS信息中包括Session-AMBR，中继终端根据Session-AMBR确定第一QoS信息中PC5 Link-AMBR。PC5 Link-AMBR的数值可以与Session-AMBR相同。
情况2，当步骤S201中获取的QoS信息只包括第一QoS信息时，第二QoS信息可以由网络侧设备(如PCF网元或SMF网元)生成，再由网络侧设备发送给中继终端，或者也可以由中继终端根据第一QoS信息生成。
需要指出的是，中继终端根据第一QoS信息生成第二QoS信息的方式类似，此处不再赘述。
在本申请实施例中，由于第一QoS信息用于传输远程终端的数据，且存在第二QoS信息时，第二QoS信息也用于传输该远程终端的数据。二者在一些QoS参数上具备相互映射的关系，例如PQI和5QI具备映射关系，PC5 Link-AMBR的数值与Session-AMBR相同等，因此第一QoS信息和第二QoS信息具备相互关联的关系，二者在传输速率和传输时延上均考虑到了远程终端到网络侧进行中继传输的业务传输需求，因此可以为远程终端提供端到端的QoS传输保障。例如，从时延角度考虑，按照现有机制传输，远程终端到中继终端和 中继终端到网络侧两段的时延可能大于远程终端的业务时延需求，这时候可以通过本申请中相互关联的第一QoS信息和第二QoS信息的配合来控制端对端的传输时延；从速率角度考虑，如果远程终端到中继终端和中继终端到网络侧两段的速率不一致，会导致在中继终端处数据丢包，因此在本申请中，可以通过将第一QoS信息和第一QoS信息中的速率参数保持一致来控制丢包率。从而充分满足远程终端到UPF网元的中继传输需求。
请参照图3，图3为本申请实施例提供的另一种管理QoS的方法的流程示意图；可包括如下步骤。
S301、远程终端向中继终端发送连接建立请求。
可选地，当远程终端不能直接连接到网络或与网络间信号质量较差时，可以发起中继发现流程。在远程终端发现中继终端后，远程终端再向中继终端发送连接建立请求，通过该中继终端建立中继传输连接，从而实现与网络的通信连接。
可选地，连接建立请求中可以包含中继通信指示信息和远程终端的第一标识信息。所述中继终端通过连接建立请求可以接收来自所述远程终端的中继通信指示信息，所述中继通信指示信息可用于指示所述远程终端进行中继通信。
S302、中继终端向AMF网元发送PDU会话建立请求。
可选的，中继终端根据已有PDU会话能否满足远程终端会话需求，确定是否建立新的PDU会话，若建立新的PDU会话则发送PDU会话建立请求消息，若不建立新的PDU会话则发送PDU会话修改请求消息。
可选的，该PDU会话专门为中继传输服务。
其中，PDU会话建立请求中可以包括中继终端的标识和远程终端的第一标识信息。通过远程终端的第一标识信息隐含指示该PDU会话为远程终端的中继传输服务。
可选的，PDU会话建立请求还可以包括中继通信指示信息，该中继通信指示信息可以用于指示该PDU会话为远程终端的中继传输服务，或者，用于指示所述远程终端进行中继通信。
需要说明的是，中继终端与AMF网元之间可以通过NAS消息传输消息，RAN设备进行透传。因此，在图3中未示出RAN设备。
S303、AMF网元向SMF网元发送PDU会话管理上下文请求。
其中，PDU会话管理上下文请求消息中可以包括中继终端的标识和远程终端的第一标识信息。当网络侧的设备接收到中继终端上报的非中继终端的标识，或者接收到中继终端上报的两个终端的标识时，便可以获知到此次传输为中继传输。因此，远程终端的第一标识信息可以用于隐含指示该PDU会话为远程终端的中继传输服务。
可选的，PDU会话管理上下文请求还可以包括中继通信指示信息，当网络侧的设备接收到中继通信指示信息时，便可以获知到此次传输为中继传输。因此，中继通信指示信息可以直接指示该PDU会话为远程终端的中继传输服务。
S304、SMF网元向PCF网元发送PDU会话策略关联请求。
在会话策略关联请求中同样可以携带远程终端的第一标识信息，或者中继通信指示信息。
其中，PCF网元是可以同时提供中继终端与UPF网元之间的通信，和PC5通信的QoS 参数授权的PCF网元。具体地，SMF网元可以在S304之前基于PCF网元的能力选择该PCF网元。
此外，SMF网元还可以为远程终端分配IP地址，并携带在PDU会话策略请求中，以方便PCF网元确定远程终端的第一标识信息与IP地址的关联关系。
S305、PCF网元生成QoS信息。
其中，该QoS信息可以包括第一QoS信息和/或第二QoS信息。第一QoS信息用于所述远程终端与所述中继终端之间传输所述远程终端的数据，第二QoS信息用于所述中继终端与用户面功能UPF网元之间传输所述远程终端的数据。
具体的，步骤S305中，PCF网元可以基于远程终端的第一标识信息或远程终端的第一标识信息和中继通信指示信息确定远程终端在中继传输通信模式下，进而确定远程终端在中继传输通信模式下的策略信息(policy info)。
其中，policy info可以是策略与计费控制(policy charging control，简称PCC)规则。Policy info可只包括第一QoS信息，用于所述远程终端与所述中继终端之间传输所述远程终端的数据，可以包括远程终端到中继终端之间的PC5通信对应的授权的QoS参数，或者可以只包括第二QoS信息，用于所述中继终端与用户面功能UPF网元之间传输所述远程终端的数据，可以包括中继终端到UPF网元之间的通信对应的授权的QoS参数，或者可以同时包括第一QoS信息和第二QoS信息。
可选的，PCF可以从UDR获取远程终端的签约信息，远程终端的签约信息中包括远程终端在中继传输通信模式下的QoS签约信息，
可选的，在步骤S304的第一种实现方式中，PCF网元可以根据远程终端的QoS签约信息生成第一QoS信息和/或第二QoS信息。远程终端的QoS签约信息可以是远程终端中继传输模式下的QoS签约信息，也可以是远程终端在直接通信模式下的QoS签约信息。直接通信模式为远程终端直接与网络通信。
具体地，QoS签约信息中可以包括每个数据网络名称(data network name，简称DNN)/单网络切片选择辅助信息(Single Network Slice Selection Assistance Information，简称S-NSSAI)对应的5QI、ARP、Session-AMBR和PC5通信对应的PQI、PC5 Link-AMBR。相应地，在S302，S303，S304中还包括DNN和S-NSSAI信息。PCF网元可以根据PDU会话的DNN和S-NSSAI信息，和该DNN/S-NSSAI对应的签约的5QI、ARP、Session-AMBR生成第一QoS信息。PCF网元可以根据PC5通信对应的签约的PQI、PC5 Link-AMBR生成第二QoS信息。
可选的，PCF还可以在信息交互时获取到中继终端的标识信息(对应于在步骤S302、S303和步骤S304中携带中继终端的标识信息)，此时PCF网元可以根据远程终端的QoS签约信息和中继终端的QoS签约信息，PCF网元生成第一QoS信息和/或第二QoS信息。远程终端的QoS签约信息可以是远程终端中继传输模式下的QoS签约信息，也可以是远程终端在直接通信模式下的QoS签约信息。
具体地，中继终端的QoS签约信息包括UE-AMBR，中继终端的UE-AMBR数值会影响到第一QoS信息中PC5 Link-AMBR和/或第二QoS信息中Session-AMBR，可以理解为第一QoS信息中PC5 Link-AMBR和/或第二QoS信息中Session-AMBR不应该超过中继终端的UE-AMBR。 PCF根据远程终端的Session-AMBR、PC5 Link-AMBR和中继终端的UE-AMBR确定第一QoS信息中PC5 Link-AMBR和/或第二QoS信息中Session-AMBR。
可选的，在步骤S304的第一种实现方式中，PCF网元根据远程终端的签约信息和远程终端的业务信息及业务需求，生成第一QoS信息和/或第二QoS信息。
具体地，PCF网元可以在信息交互(例如，在步骤S301、S302、S303和步骤S304中携带业务信息)时，获取到远程终端的业务信息(例如，可包括但不限于业务类型如语音业务、数据业务、视频业务等)和业务需求(如时延需求、速率需求等)。
例如，远程终端的QoS签约信息中包括DNN/S-NSSAI对应的签约的5QI和PC5通信对应的签约的PQI，业务需求可以为具体的传输时延需求，PCF根据5QI和/或PQI中数据包时延预算(packet delay budget)数值和业务传输时延需求，确定第一QoS信息中PQI和/或第二QoS信息中5QI。
再例如，远程终端的QoS签约信息中包括Subscribed GBR(理解为所有GBR QoS流的最大聚合比特速率)，业务需求可以为具体的传输速率需求，PCF根据Subscribed GBR和业务传输速率需求，确定第一QoS信息中与业务对应的GFBR和/或第二QoS信息中与业务对应的GFBR。进一步，PCF根据Subscribed GBR和已有GBR QoS流对应的GFBR以及业务传输速率需求，确定第一QoS信息中与业务对应的GFBR和/或第二QoS信息中与业务对应的GFBR，已确保所有GBR QoS流的GFBR之和小于Subscribed GBR。
可选的，在步骤S305第三种实现方式中，PCF网元根据所述远程终端的签约信息，所述中继终端的签约信息以及所述远程终端的业务信息，生成第一QoS信息和/或第二QoS信息。
具体地，PCF可以获取到中继终端的标识信息和所述远程终端的业务信息，PCF网元根据所述远程终端的签约信息，所述中继终端的签约信息以及所述远程终端的业务信息，生成第一QoS信息和/或第二QoS信息。
例如，远程终端的QoS签约信息中包括DNN/S-NSSAI对应的签约的5QI和PC5通信对应的签约的PQI，中继终端的QoS签约信息中包括DNN/S-NSSAI对应的签约的5QI和PC5通信对应的签约的PQI，业务需求可以为具体的传输时延需求，PCF根据5QI和/或PQI中数据包时延预算(packet delay budget)数值和业务传输时延需求，确定第一QoS信息中PQI和/或第二QoS信息中5QI，所确定后的PQI和/或5QI应该与中继终端的QoS签约信息中包括DNN/S-NSSAI对应的签约的5QI和PC5通信对应的签约的PQI相符。
再例如，远程终端的QoS签约信息中包括Subscribed GBR，中继终端的QoS签约信息中也包括Subscribed GBR，业务需求可以为具体的传输速率需求，PCF根据远程终端的Subscribed GBR和中继终端的Subscribed GBR以及业务传输速率需求，确定第一QoS信息中与业务对应的GFBR和/或第二QoS信息中与业务对应的GFBR，所确定后的GFBR应该同时小于远程终端的QoS签约信息中Subscribed GBR和中继终端的QoS签约信息中Subscribed GBR。
S306、PCF网元向SMF网元发送PDU会话策略关联请求响应。
其中，PDU会话策略关联请求响应携带QoS信息。
S307、SMF网元向AMF网元发送PDU会话上下文请求响应。
其中，PDU会话上下文请求响应携带QoS信息。
S308、AMF网元向中继终端发送PDU会话建立请求响应。
其中，PDU会话建立请求响应携带QoS信息。该QoS信息中可以包括第一QoS信息和/或第二QoS信息。
需要说明的是，当该QoS信息只包括第一QoS信息时，第二QoS信息可以由网络侧设备(如SMF网元或PCF网元)另外单独发送给中继终端，或者也可以由中继终端或远程终端生成。当该QoS信息只包括第二QoS信息时，可以由中继终端根据第二QoS信息生成第一QoS信息并发送给远程终端。
S309、中继终端根据生成的QoS信息，存储第一QoS信息。
可选地，当中继终端接收到的QoS信息中包含第一QoS信息时，直接进行存储，当中继终端接收到的QoS信息中不包含第一QoS信息时，则由中继终端根据第二QoS信息生成第一QoS信息并进行存储。
S310、中继终端向远程终端发送连接建立请求响应。
其中，连接建立请求响应携带第一QoS信息。
通过上述流程，便可以使得远程终端获取到符合自身业务传输需求的QoS信息，且中继终端与网络侧的UPF网元之间进行业务传输的第二QoS信息与第一QoS信息相关联，从而可以确保远程终端到UPF网元的端对端业务传输的QoS保障。
可选地，在步骤S306之后，SMF网元还可以根据第一QoS信息生成第一QoS流信息，根据第二QoS信息生成第二QoS流信息。第一QoS流信息用于承载远程终端与中继终端之间所述远程终端的数据，所述第二QoS流信息用于承载所述中继终端与用户面功能UPF网元之间所述远程终端的数据。可选地，第一QoS流信息可以包括QFI、GFBR、MFBR、流规则(QoS rule)。第二QoS流信息可以包括PFI、GFBR、MFBR、流规则。
具体地，SMF网元根据第一QoS信息确定是否有已有QoS流与第一QoS信息相对应，可以判断第一QoS信息中PQI与已有QoS流的PQI是否相同。若相同，将第一QoS信息与已有QoS流相关联，更新该QoS流信息(如GFBR和MFBR)，生成第一QoS流信息；若不能对应，建立新QoS流，生成第一QoS流信息。根据第二QoS信息生成第二QoS流信息类似，此处不再赘述。
SMF网元可以将生成的QoS流信息下发给中继终端。
可选地，在步骤S305中，PCF也可以生成一个整体的用于远程终端到UPF网元之间传输所述远程终端的数据的QoS信息，此时SMF网元可以根据该QoS信息生成第一QoS流信息和/或第二QoS流信息。
与QoS信息下发类似，下发的QoS流信息同样可以包括第一QoS流信息和/或第二QoS流信息，当只包括第一QoS流信息时，第二流QoS信息可以由网络侧设备如SMF网元或PCF网元另外单独发送给中继终端，或者也可以由中继终端或远程终端生成。当只包括第二QoS流信息时，可以由中继终端根据第二QoS流信息生成第一QoS流信息并发送给远程终端。
可选地，中继终端根据第二QoS流信息生成第一QoS流信息，可通过如下方式进行：
方式一、第二QoS流信息中包括QFI，中继终端根据第二QoS流信息中的QFI确定第一QoS流信息中的PFI。例如，QFI的数值可以与PFI的数值相同。例如，QFI和PFI的数 值可以都为50，或者，二者的数值也可以不同，但二者具备映射关系，该映射关系可以由中继终端进行保存。
方式二、第二QoS流信息中包括GFBR，中继终端根据第二QoS流信息中的GFBR确定第一QoS流信息中的GFBR。第一QoS流信息和第二QoS流信息中GFBR的数值相同。例如二者的数值均为10Mb/s。
方式三、第二QoS流信息中包括MFBR，中继终端根据第二QoS流信息中的MFBR确定第一QoS流信息中的MFBR。例如，第一QoS流信息和第二QoS流信息中MFBR的数值相同。例如，二者的数据均为20Mb/s。
方式四、第二QoS流信息中包括流规则，中继终端根据第二QoS流信息中的流规则确定第一QoS流信息中流规则。在流规则中示出了IP地址，端口号等于流标识的映射关系，例如，第一QoS流信息和第二QoS流信息中流规则相同。二者的流规则中都包括远程终端的ip，相同的端口号如端口2，数值相同的流标识如均为50的QFI和PFI。
需要说明的是，当第二QoS流信息包括多个参数(例如，QFI、MFBR、GFBR等的各种组合)时，中继终端根据第二QoS流信息生成第一QoS流信息可以包括该多个参数对应的方式，不予限制。
中继终端还可以存储第一QoS流信息，并向远程终端下发第一QoS流信息。
以上为本申请实施例在PDU会话建立过程中的具体实现方式，对于已有的PDU会话，则可以通过PDU会话修改的流程来管理已有的QoS信息。
此时，在步骤S301中连接建立请求将变为连接修改请求，S302中的PDU会话建立请求将变为PDU会话修改请求，步骤S304中的PDU会话策略关联请求变为PDU会话策略关联修改请求。可选的，在步骤S302-S303的两个请求消息中可以包括PDU会话相关标识信息(如PDU会话修改请求中包括PDU session ID，PDU会话策略关联修改请求包括SM Policy Association ID)，此时，可以不用携带远程终端的第一标识信息，也可以不用携带中继终端的标识信息，因为PDU会话建立完成后SMF和PCF已知PDU session ID/SM Policy Association ID对应的远程终端的第一标识信息和中继终端的标识信息。其余步骤基本与S305-S310的描述相同，此处不再赘述。
通过该实施例的实现方式，可以由网络侧确定远程终端到中继终端以及中继终端到UPF网元的两段相关联的QoS信息，为远程终端的端对端业务提供良好的QoS管理和业务传输保障。
请参照图4，为本申请实施例提供的又一种管理QoS的方法的流程示意图，在该实施例中，可以由应用功能AF网元根据远程终端请求的业务来触发PCF网元生成相应的QoS信息。可选地，远程终端的IP地址可以由中继终端为其分配，也可以由SMF网元为其分配，下面以中继终端为远程终端分配IP地址为例进行描述说明。
S401、远程终端向中继终端发送连接建立请求。
S402、中继终端根据连接建立请求建立PDU会话，为远程终端分配IP地址。
中继终端在建立PDU会话时，可以确定为该PDU会话服务的SMF网元和PCF网元。且中继终端可以从SMF网元获取为其分配的IP地址，并为远程终端分配IP地址。可选的，中继终端根据SMF网元分配的IP地址确定远程终端的IP地址。
S403、中继终端向AMF网元发送PDU会话修改请求。
其中，PDU会话修改请求携带远程终端的第二标识信息。其中，第二标识信息包括远程终端的IP地址，进一步还可以包括远程终端的ID。ID的相关介绍可参见图2中步骤S202之前的描述。
示例性地，当S403中中继终端为远程终端分配IP地址时，中继终端发起PDU会话修改流程，上报远程终端的第二标识信息。
S404、AMF网元向SMF网元发送PDU会话管理上下文请求。
其中，该PDU会话管理上下文请求携带远程终端的第二标识信息。
其中，第二标识信息可以用于作为远程终端的标识，与第一标识信息不同。如第二标识信息可以是远程终端的IP地址，此时第一标识信息可以是远程终端的ID。
S405、SMF网元向PCF网元发送PDU会话策略关联请求。
其中，PDU会话策略关联请求可以用于向PCF网元请求该PDU会话对应的QoS策略。
其中，PDU会话策略关联请求携带远程终端的第二标识信息。
示例性地，当PCF网元获取到第二标识信息中远程终端的IP地址之后，可以请求绑定支持功能(Binding Support Function，简称BSF)网元绑定PCF网元与远程终端IP地址的映射关系，PCF也可以记录远程终端当前为中继传输状态。
需要说明的，步骤S403、S404、S405中的各个请求消息主要用于上报远程终端的IP地址，每个请求消息均有对应的响应消息，如与S403中PDU会话修改请求对应的“PDU会话修改请求响应”，与S404中PDU会话管理上下文请求对应的“PDU会话管理上下文请求响应”，与S405中PDU会话策略关联请求响应对应的“PDU会话策略关联请求响应”。这些响应消息可用于向发起请求消息的设备进行反馈，告知发起请求消息的设备已收到该请求消息以及其中携带的IP地址。
此外，在步骤S402之后，同样有对S401中的连接建立响应对应的“连接建立请求响应”。上述响应消息作为远程终端到PCF网元的信息交互的一部分，主要用于对相应请求消息的确认回复，与触发PCF网元生成QoS信息的关联不大，因此在图4中并未示出。
S406、AF网元向PCF网元发送策略授权请求。
AF网元可以获取到远程终端的IP地址，具体可以通过远程终端和应用服务器通过应用层实现。AF网元向BSF网元获取远程终端的IP地址对应的PCF网元。AF网元根据远程终端请求的业务向相应的PCF发送策略授权请求，触发PCF网元来生成相应的QoS信息。
S407、PCF网元生成QoS信息。
S408、PCF网元向SMF网元发送PDU会话策略关联修改请求。
其中，PDU会话策略修改请求可以携带生成的QoS信息。
S409、SMF网元向AMF网元发送PDU会话上下文更新请求。
其中，PDU会话上下文更新请求可以携带生成的QoS信息。

可选的，当中继终端接收到授权信息之后，可以根据其中包括的授权指示或已授权的第六QoS信息判断在步骤S502中的第三QoS信息是否需要修改，如果不需要修改则将第三QoS信息作为供远程终端使用的第七QoS信息发送给远程终端；如果需要修改，例如第六QoS信息中限制的传输速率小于第三QoS信息中的传输速率，此时则可以对第三QoS信息进行更新，然后将更新后得到的第七QoS信息发送给远程终端。
需要说明的是，中继终端生成第三QoS信息时基于提前从网络侧PCF网元获取的PC5QoS参数，PCF网元在生成包含已授权的第六QoS信息时可以结合中继终端的PC5 QoS参数进行统筹考虑，在这种情况下默认已生成的第三QoS信息不需要修改，这样步骤S510可以省略。直接执行步骤S511。
S511、中继终端向远程终端发送连接建立请求响应。

可选地，若连接建立请求中还包括远程终端请求的业务信息，则中继终端还可以基于该业务信息和PC5 QoS参数生成第四QoS信息。
可选地，中继终端基于自己获取到的信息(如PC5 QoS参数和/或业务信息)来对远程终端生成的第三QoS信息进行可用性评估，例如，远程终端的第三QoS信息中PC5 LINK AMBR大于中继终端能支持的PC5 LINK AMBR，则中继终端将自己支持的PC5 LINK AMBR信息发送给远程终端。
