示例性地，UE1和UE2通过PC5通信链路交互视频业务时，UE1和UE2分别根据从应用层获得的应用层业务标识确定传输时延为200ms。需要说明的是，这里所指的传输时延为视频业务的业务数据从UE1与到UE2，或者，视频业务的业务数据从UE2到UE1的传输时延。
在图1所示的场景中，当两个具有prose能力的UE由于距离较远或其他某些原因，无法通过PC5接口建立直接通信时，可以通过另一个具有prose能力的UE进行通信的中转，该用于通信中转的UE即作为中继节点。如图2所示，UE-R可通过PC5接口与UE1进行直接通信，UE-R还可通过PC5接口与UE2进行直接通信，即UE1和UE2可通过UE-R进行业务交互。
若UE1请求进行UE1与UE2之间的业务交互，UE1可通过UE-R与UE2进行业务交互。在现有技术中，由于进行业务交互的两个终端设备各自根据业务确定业务数据在交互过程中的QoS参数。如上述图2所示的场景中，UE1和UE2各自根据业务确定业务数据传输对应的QoS参数，即UE1根据业务确定业务数据在UE1和UE-R之间交互的第一QoS参数，UE2根据业务确定业务数据在UE2和UE-R之间交互的第二QoS参数。
例如，UE1和UE2交互一种端到端传输时延为200毫秒(ms)的视频业务，UE1根据业务确定UE1与UE-R之间传输时延为200ms，UE2和UE-R根据业务确定PC5接口上的传输时延也是200ms，则该业务的实际传输时延为UE1到UE-R之间的传输时延与UE-R到UE2之间的传输时延之和，即该业务的实际传输时延为400ms，这造成UE1与UE2之间传输的业务数据的数据传输质量无法得到保证。
因此，本申请实施例提供一种QoS控制方法，通过源UE根据应用的触发向目标UE发送请求信息，其中请求信息包括业务数据在源UE和目标UE之间传输的QoS信息。中继UE收到源UE向目标UE发起的请求信息，可以获得业务数据在源UE和中继UE之间传输的QoS信息，以及业务数据在中继UE和目标UE之间传输的QoS信息，从而保证了源UE通过中继UE与目标UE进行业务交互的数 据传输质量。
在介绍本实施例提供的QoS控制方法之前，首先对本申请实施例涉及的实施环境进行介绍。
本申请实施例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、LTE FDD(Frequency Division Duplex，频分双工)系统、LTE TDD(Time Division Duplex，时分双工)系统、LTE-A(Advanced long term evolution，先进的长期演进)系统、NR(New Radio，新无线)系统、NR系统的演进系统、LTE-U(LTE-Based Access To Unlicensed Spectrum，非授权频段上的LTE)系统、NR-U(NR-Based Access To Unlicensed Spectrum，非授权频段上的NR)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、WLAN(Wireless Local Area Networks，无线局域网)、WiFi(Wireless Fidelity，无线保真)、下一代通信系统或其他通信系统等。

下面对本申请实施例提供的QoS控制方法进行详细介绍，本申请提供的QoS控制方法包括以下内容中的至少部分内容。
图4为本申请一实施例提供的QoS控制方法的流程图。如图4所示，本实施例的方法包括：
S101、第二终端设备向第一终端设备发送第一信息。
首先，需要说明的是，第一终端设备、第二终端设备以及第三终端设备均具备prose能力，第二终端设备与第三终端设备之间无法建立直接通信链路，因此，第二终端设备与第三终端设备之间的通信需要第一终端设备进行中转，也就是说，第二终端设备与第三终端设备之间的业务交互需要通过第一终端设备进行中转。
第二终端设备向第一终端设备发送第一信息，相应地，第一终端设备接收第二终端设备发送的第一信息。可选地，第二终端设备可以通过广播的形式发送第一信息，或者，也可以在第二终端设备与第一终端设备建立的通信链路上发送，则第一终端设备可以通过监听广播的形式，或者，直接在第一终端设备与第二终端设备建立的通信链路上接收该第一信息。其中，该第一信息用于请求进行第二终端设备与第三终端设备之间的业务交互。可选地，上述业务包括但不限于为视频业务、文本传输业务、图像传输业务、音频传输业务等等。

例如，第一信息包括视频业务交互在第二终端设备与第三终端设备之间的端到端传输时延为200ms；若预设或标准化如下表1所示的PQI映射表，则第一信息可以包括PQI的值，通过PQI的值指示端到端传输时延。其中，PQI(PC5 5QI)表示PC5 5G QoS标识。
表1
PQI 业务的优先级 时延 误码率
95 2 200ms 10 -2
58 4 100ms 10 -2
57 5 25ms 10 -2
另一种可能的实现方式中，第一信息包括业务交互在第二终端设备与第三终端设备之间的端到端QoS信息以及第一QoS信息，其中，第一QoS信息为业务交互在第一终端设备与第二终端设备之间的QoS信息。其中，第一QoS信息包括但不限于业务的业务数据从第二终端设备到第一终端设备，或者，业务的业务数据从第一终端设备到第二终端设备的传输时延、带宽、误码率、业务的优先级等QoS参数。
可选地，该端到端QoS信息可以为端到端QoS信息的标识，或者端到端QoS参数的取值，或者QoS参数的取值范围。第一QoS信息可以为第一QoS信息的标识，或者第一QoS参数的取值，或者QoS参数的取值范围。
例如，第一信息包括视频业务交互在第二终端设备与第三终端设备之间的端到端传输时延，以及视频业务交互在第二终端设备与第一终端设备之间的传输时延，如端到端传输时延为200ms以及第二终端设备与第一终端设备之间的传输时延100ms。若预设或标准化如上表1所示的PQI映射表，则第一信息可以包括两个PQI的值，通过两个PQI的值分别指示端到端传输时延以及视频业务交互在第二终端设备与第一终端设备之间的传输时延。
另一种可能的实现方式中，第一信息包括第一QoS信息以及第二QoS信息，其中，第一QoS信息为业务交互在第一终端设备与第二终端设备之间的QoS信息，第二QoS信息为业务交互在第一终端设备与第三终端设备之间的QoS信息。其中，第二QoS信息包括但不限于业务交互在第二终端设备与第一终端设备之间的传输时延、带宽、误码率、业务的优先级等QoS参数，以及业务交互在第一终端设备与第三终端设备之间的传输时延、带宽、误码率、业务的优先级等QoS参数。
另一种可能的实现方式中，第一信息包括业务交互在第二终端设备与第一终端设备之间的第一QoS信息，以及业务交互在第三终端设备与第一终端设备之间的第二QoS信息；其中，第一QoS信息包括但不限于业务的业务数据从第二终端设备到第一终端设备，或者，业务的业务数据从第一终端设备到第二终端设备的传输时延、带宽、误码率等QoS参数。其中，第二QoS信息包括但不限于业务的业务数据从第三终端设备到第一终端设备，或者，业务的业务数据从第一终端设备到第三终端设备的传输时延、带宽、误码率、业务的优先级等QoS参数。

例如，视频业务交互在第二终端设备与第三终端设备之间的端到端传输时延需求为200ms，视频业务交互在第二终端设备与第一终端设备之间的传输时延需求为100ms，视频业务交互在第一终端设备与第三终端设备之间的传输时延需求为100ms，则第一信息可以包括第一QoS信息为100ms，以及第二QoS信息为100ms。若预设或标准化如上表1所示的PQI映射表，则第一信息可以包括两个PQI的值，通过两个PQI的值分别指示视频业务交互在第二终端设备与第一终端设备之间的传输时延以及视频业务交互在第一终端设备与第三终端设备之间的传输时延。
S102、第一终端设备根据第一信息，获取第二QoS信息。
具体地，第一终端设备接收第一信息后，可根据第一信息，获取业务交互在第一终端设备与第三终端设备之间的QoS信息，即第二QoS信息。
在一些情况下，第一信息包括端到端QoS信息，则第一终端设备先获取业务交互在第一终端设备与第二终端设备之间的QoS信息，即第一QoS信息；并根据端到端QoS信息以及第一QoS信息，获取第二QoS信息。第一终端设备通过上述方式能够获取第一QoS信息和第二QoS信息，该第一QoS信息和第二QoS信息共同满足上述端到端QoS信息。
可选地，第一终端设备获取第一QoS信息可通过下述方式实现：
一种可能的实现方式，第一终端设备可根据第一终端设备与第二终端设备之间的信号传输质量，获取第一QoS信息。示例性地，第一终端设备根据无线信号测量的相关信息，进行无线功率或者路径损耗等相关计算，获取所述第一QoS信息。其中，该无线信号测量的相关信息可以是接收到第一信息后进行无线信号测量获得的，也可以是第一终端设备与第二终端设备在建立通信链路时获得的相关测量结果，或者，也可以是第一终端设备与第二终端设备在上一次业务交互过程中，获取第一QoS信息时采用的无线信号测量的相关信息，本申请实施例对此不作限制，无线信号测量的相关信息只要能够反映第一终端设备与第二终端设备当前状态下进行第一信息请求的业务时的信号传输质量即可。
另一种可能的实现方式，第一终端设备根据第一信息携带的时间戳以及当前时刻，获取第一QoS信息。其中，第一信息携带的时间戳为第二终端设备发送第一信息的时刻，时间戳也可以称为时间标签、发送时刻等其他名称。即第一终端设备可通过对比第一信息携带的时间戳以及当前时刻，获取第一信息由第二终端设备传输至第一终端设备的时间长度，从而获取业务交互在第一终端设备与第二终端设备之间的QoS信息。
另一种可能的实现方式，第一信息包括第一QoS信息，如第一信息包括端到端QoS信息和第一QoS信息，则第一终端设备可直接从第一信息中获取第一QoS信息。
在另一些情况下，第一信息包括第一QoS信息和第二QoS信息，则第一终端设备可从第一信息中获取第一QoS信息和第二QoS信息。
需要说明的是，在上述几种可能的实现方式中，获取的第一QoS信息可以为QoS参数的取值，或者，也可以为QoS参数支持的取值范围，本申请实施例对此不作限制。
S103、第一终端设备向第三终端设备发送第二QoS信息。
第一终端设备向第三终端设备发送第二QoS信息，相应地，第三终端设备接收第一终端设备发送的第二QoS信息，从而获取业务交互在第一终端设备与第三终端设备之间的QoS信息。
需要说明的是，若第一QoS信息为QoS参数的取值范围，相应地，第二QoS信息也可以为QoS参数的取值范围。第一终端设备通过将第二QoS参数的取值范围发送至第三终端设备，第三终端设备可根据第二QoS参数的取值范围，确定第二QoS参数的取值。
本实施例中，第二终端设备向第一终端设备发送用于请求进行第二终端设备与第三终端设备之间的业务交互的第一信息；第一终端设备根据第一信息，获取业务交互在第一终端设备与第三终端设备之间的QoS信息，并向第三终端设备发送该第二QoS信息。通过上述方式，第一终端设备和第三终端设备能够获得业务交互在第一终端设备与第三终端设备之间的QoS信息，即第二QoS信息，该第二QoS信息能够满足端到端QoS信息，从而保证业务在第二终端设备与第三终端设备之间传输的数据传输质量。另外，第一终端设备能够获取业务交互在第一终端设备与第二终端设备之间的第一QoS信息，并通过第一QoS信息和第二QoS信息共同保证业务的业务数据在第二终端设备与第三终端设备之间传输的数据传输质量。
在图4所示实施例的基础上，在第一信息包括端到端QoS信息以及第一QoS信息的情况下，或者，第一信息包括第一QoS信息和第二QoS信息的情况下，第一终端向第三终端设备发送第二QoS信息后，第三终端设备确定无需更新第二QoS信息，此时，第一终端设备可根据第一信息，直接获取第一QoS信息，第二终端设备也可以获取第一QoS信息。则执行上述S101至S103，即可使第二终端设备、第一终端设备以及第三终端设备均能够获取相应的QoS信息，从而保证业务的业务数据通过第一终端设备，交互在第二终端设备与第三终端设备之间的数据传输质量。
在第一信息包括端到端QoS信息，但并未包括第一QoS信息的情况下，第一终端设备向第三终端设备发送第二QoS信息后，第三终端设备确定无需更新第二QoS信息，此时，第二终端设备无法确定第一QoS信息，因此，需要由第一终端设备向第二终端设备指示第一QoS信息。另外，若预先设定，无论第一信息包括哪些参数，均由第一终端设备分别向第二终端设备和第三终端设备指示第一QoS信息和第二QoS信息，则无论第二终端设备是否能够确定第一QoS信息，第一终端设备也需要向第二终端设备指示第一QoS信息。
因此，可选地，在图4所示实施例的基础上，还可以包括：
S104、第一终端设备向第二终端设备发送第一QoS信息。
本实施例中，通过第一终端设备获取第一QoS信息，并向第二终端设备指示第一QoS信息，以使第一终端设备能够获得业务交互在第一终端设备与第二终端设备之间的QoS信息，从而保证业务通过第一终端设备，交互在第二终端设备与第三终端设备之间的服务质量。
图5为本申请另一实施例提供的QoS控制方法的流程图。如图5所示，本实施例的方法包括：
S201、第二终端设备向第一终端设备发送第一信息，其中，第一信息包括端到端QoS信息。
S202、第一终端设备根据第一信息，获取第二QoS信息。
S203、第一终端设备向第三终端设备发送第二QoS信息。
本实施例中S201至S203可参照图4所示实施例中S101至S103类似，可参照图4所示实施例的详细描述，此处不再赘述。
在一些情况下，第一终端设备向第三终端设备发送第二QoS信息后，第三终端设备确定需要更新第二QoS信息，则需要重新确定第二QoS信息以及第一QoS信息。因此，在这样的情况下，S203之后，可执行S204至S207。
S204、第三终端设备重新确定第二QoS信息。
示例性地，第三终端设备可以根据预先配置的数据传输策略、第三终端设备的数据处理能力、数据传输能力、以及应用相关的配置信息等信息中的一项或多项，重新确定第二QoS信息。
示例性地，若第一终端设备向第三终端设备发送的是第二QoS参数的取值范围，则第三终端设备可根据第二QoS参数的取值范围，确定第二QoS参数的值，该过程即为重新确定第二QoS信息。
举例来说，第二终端设备与第三终端设备之间交互的视频业务的端到端传输时延为200ms，第一终端设备确定视频业务交互在第一终端设备与第二终端设备之间的第一传输时延为[100,175]ms的范围，则第一终端设备根据第一传输时延[100,175]ms的范围以及端到端传输时延为200ms，确定视频业务交互在第一终端设备与第三终端设备之间的第二传输时延为[25,100]ms，则第一终端设备向第三终端设备发送第二传输时延[25,100]ms的范围。第三终端设备根据第二传输时延[25,100]ms的范围，重新确定第二传输时延为100ms。
或者，若第三终端设备确定第一终端设备发送的第二QoS参数无法适用，则需要对第二QoS参数的值进行更新，重新确定第二QoS信息。举例来说，第二终端设备与第三终端设备之间交互的视频业务的端到端传输时延为200ms，第一终端设备确定视频业务交互在第一终端设备与第二终端设备之间的第一传输时延为100ms，则第一终端设备根据第一传输时延100ms以及端到端传输时延为200ms，确定视频业务交互在第一终端设备与第三终端设备之间的第二传输时延为100ms，则第一终端设备向第三终端设备发送第二传输时延100ms。第三终端设备确定第二传输时延100ms无法满足，则重新确定第二传输时延为120ms。
需要说明的是，本申请实施例对于第三终端设备重新确定第二QoS信息的具体实现方式并不限制。
S205、第三终端设备向第一终端设备发送第二信息，其中，第二信息包括第三终端设备重新确定的第二QoS信息。
相应地，第一终端设备接收第三终端设备发送的第二信息，从而获取第三终端设备重新确定的第二QoS信息。例如，第一终端设备可以通过广播的形式发送第二QoS信息，或者第一终端设备还可以在与第三终端设备已经建立的通信链路上发送第二QoS信息，但是本申请实施例并不限于通过上述两种方式发送第二QoS信息。
S206、第一终端设备根据第三终端设备重新确定的第二QoS信息，重新确定第一QoS信息。
S207、第一终端设备向第二终端设备发送第一QoS信息。
具体地，第三终端设备重新确定第二QoS信息，并向第一终端设备发送的重新确定的第二QoS信息；第一终端设备接收第三终端设备发送的重新确定的第二QoS信息，并根据重新确定的第二QoS信息，重新确定第一QoS信息；第一终端设备将重新确定的第一QoS信息发送至第二终端设备。
参照S204中的举例，若第一终端设备确定视频业务交互在第一终端设备与第二终端设备之间的第一传输时延为[100,175]ms的范围，视频业务交互在第一终端设备与第三终端设备之间的第二传输时延 为[25,100]ms，且第一终端设备接收第三终端设备返回的重新确定的第二传输时延为100ms，则第一终端设备可根据第三终端设备重新确定的第二传输时延为100ms，重新确定第一传输时延为100ms，并向第二终端设备发送重新确定的第一传输时延为100ms。
若第一终端设备确定视频业务交互在第一终端设备与第二终端设备之间的第一传输时延为100ms，视频业务交互在第一终端设备与第三终端设备之间的第二传输时延为100ms，第三终端设备重新确定第二传输时延为120ms，则第一终端设备根据第三终端设备重新确定的第二传输时延120ms，重新确定第一传输时延为80ms，并向第二终端设备发送重新确定的第一传输时延为80ms。
本实施例中，第三终端设备通过重新确定第二QoS信息，并将重新确定的第二QoS信息发送至第一终端设备，以使第一终端设备获得业务在第一终端设备与第三终端设备之间的QoS信息。另外，第一终端设备根据第三终端设备重新确定的第二QoS信息，重新确定第一QoS信息，并将重新确定的第一QoS信息发送至第二终端设备，以使第二终端设备获取重新确定的第一QoS信息。通过上述重新确定的第一QoS信息以及重新确定的第二QoS信息，从而保证业务交互在第二终端设备与第三终端设备之间能够满足端到端QoS要求，保证业务的服务质量。
下面根据第一信息包括端到端QoS信息，或者，端到端QoS信息和第一QoS信息，或者，第一QoS信息和第二QoS信息三种情况分别进行详细介绍。下述几个实施例中进行举例时，均以第二终端设备请求进行第二终端设备与第三终端设备之间的视频业务为例进行说明，该视频业务交互在第二终端设备与第三终端设备之间端到端QoS信息包括传输时延，且端到端传输时延为200ms。
图6为本申请另一实施例提供的QoS控制方法的流程图。本实施例中，第一信息包括端到端QoS信息。如图6所示，本实施例的方法包括：
S301、第二终端设备向第一终端设备发送直接通信建立或修改请求信息，直接通信建立或修改请求信息包括端到端QoS信息。
具体地，第二终端设备根据应用的触发，确定所发起的业务的端到端QoS信息，并发起目标为第三终端设备的PC5连接的直接通信建立或修改请求。本实施例中，直接通信建立或修改请求信息即为前述实施例中的第一信息，直接通信建立或修改请求信息包括端到端QoS信息。
其中，第二终端设备可以广播的形式发送直接通信建立或修改请求信息，或者也可以是在第二终端设备已经与第一终端设备已经建立的通信链路上发送直接通信建立或修改请求信息，本申请实施例对此不作限制。
举例来说，对于预先配置或者标准化的PQI映射如上表1所示，则第二终端设备可以提供PQI＝95表示端到端传输时延为200ms的时延要求，当然具体QoS参数也可以不是PQI，而是直接表示为端到端传输时延200ms的时延要求或者其他可以进行映射的参数。
S302、第一终端设备获取第一QoS信息。
其中，第一终端设备获取的第一QoS信息可以为QoS参数的具体取值，也可以为QoS参数的取值范围，或者还可以是PQI值。
本实施例中，若直接通信建立或修改请求信息包括端到端QoS信息，则第一终端设备可通过无线测量的相关信息，获取第一QoS信息，或者，根据直接通信建立或修改请求信息携带的时间戳以及当前时刻，获取第一QoS信息。详细可参照图4所示实施例中第一信息包括端到端QoS信息的情况的详细描述，此处不再赘述。
S303、第一终端设备根据端到端QoS信息以及第一QoS信息，获取第二QoS信息。
S304、第一终端设备向第三终端设备发送第二QoS信息。
相应地，第三终端设备接收第一终端设备发送的第二QoS信息。例如，第一终端设备可以通过广播的形式发送第二QoS信息，或者第一终端设备还可以在与第三终端设备已经建立的通信链路上发送第二QoS信息，但是本申请实施例并不限于通过上述两种方式发送第二QoS信息。
本实施例中，第二终端设备向第一终端设备发送用于请求进行第二终端设备与第三终端设备之间的业务交互的直接通信建立或修改请求信息；第一终端设备根据直接通信建立或修改请求信息，获取业务交互在第一终端设备与第三终端设备之间的第二QoS信息，并向第三终端设备发送该第二QoS信息。通过上述方式，第一终端设备和第三终端设备能够获得业务交互在第一终端设备与第三终端设备之间的QoS信息，即第二QoS信息，该第二QoS信息能够满足端到端QoS信息，从而保证业务在第二终端设备与第三终端设备之间传输的数据传输质量。另外，第一终端设备能够获取业务交互在第一终端设备与第二终端设备之间的第一QoS信息，并通过第一QoS信息和第二QoS信息共同保证业务在第二终端设备与第三终端设备之间传输的数据传输质量。
可选地，在本实施例中，还可以包括步骤S304＇：
S304＇、第一终端设备向第三终端设备发送端到端QoS信息。
相应地，第三终端设备接收第一终端设备发送的端到端QoS信息。例如，第三终端设备确定需要重新确定第二QoS信息时，该端到端QoS信息可为第三终端设备提供相应的依据。
其中，S304和S304＇可以通过同一信息发送，也可以通过不同信息发送，且S304和S304＇的执行顺序不分先后。
S305、第一终端设备向第二终端设备发送第一QoS信息。
相应地，第二终端设备接收第一终端设备发送的第一QoS信息，从而获取业务交互在第一终端设备与第二终端设备之间的QoS信息。
需要说明的是，在一些情况下，S305与S303的执行顺序不分先后。
例如，第一终端设备向第三终端设备发送第二QoS信息后，若第三终端设备无需更新第二QoS信息，在这样的情况下，第一终端设备也无需对第一QoS信息进行更新，则第一终端设备获取第一QoS信息之后，可将第一QoS信息发送至第二终端设备，因此，S305与S303的执行顺序可不分先后。
举例来说，若视频业务交互在第二终端设备与第三终端设备之间的端到端传输时延为200ms；视频业务在交互在第二终端设备与第一终端设备之间的传输时延为100ms，即第一QoS信息为100ms；视频业务交互在第一终端设备与第三终端设备之间的传输时延为100ms，即第二QoS信息为100ms；第三终端设备接收第一终端设备发送的第二QoS信息后，确定无需对第二QoS信息进行更新，则第二终端设备、第一终端设备以及第三终端设备根据上述第一QoS信息以及第二QoS信息进行视频业务数据的传输，从而保证视频业务数据在第二终端设备与第三终端设备之间的数据传输质量。
在另一些情况下，第一终端设备向第三终端设备发送第二QoS信息后，第三终端设备确定需要更新第二QoS信息，则会向第一终端设备发送反馈信息，以向第一终端设备发送第三终端设备重新确定的第二QoS信息。因此，在这样的情况下，第一终端设备获取第三终端设备返回的重新确定的第二QoS信息，并根据重新确定的第二QoS信息，重新确定第一QoS信息。因此，可选地，S305之前，还包括：
S3051、第三终端设备重新确定第二QoS信息。
示例性地，第三终端设备可以根据预先配置的数据传输策略、第三终端设备的数据处理能力、数据传输能力、以及应用相关的配置信息等信息中的一项或多项，重新确定第二QoS信息。
需要说明的是，本申请实施例对于第三终端设备重新确定第二QoS信息的具体实现方式并不限制。
S3052、第三终端设备向第一终端设备发送第二信息，第二信息包括第三终端设备重新确定的第二QoS信息。
S3053、第一终端设备根据第二信息，重新确定第一QoS信息。

则相应地，在第三终端设备未向第一终端设备发送重新确定的端到端QoS信息的情况下，第一终端设备可根据原先的端到端QoS信息以及重新确定的第二QoS信息，重新确定第一QoS信息；若第三终端设备向第一终端设备发送重新确定的端到端QoS信息的情况下，第一终端设备可根据第三终端设备发送的重新确定的端到端QoS信息以及重新确定的第二QoS信息，重新确定第一QoS信息。

需要说明的是，在本实施例中，第二终端设备也可通过向第一终端设备发送一组PQI值，以分别表示端到端QoS信息和第一QoS信息。举例来说，第二终端设备向第一终端设备发送PQI＝[95，58]，以分别指示端到端传输时延为200ms，以及第一传输时延为100ms。当然，第二终端设备也可以直接表示端到端传输时延为200ms以及第一传输时延为100ms，或者其他可映射的参数。

具体地，第一终端设备可根据直接通信建立或修改请求信息，直接获取第一QoS信息。本实施例与图6所示实施例的区别在于：第一终端设备接收直接通信建立或修改请求信息后，可通过直接通信建立或修改请求信息直接获取第一QoS信息，无需根据无线信号测量的相关信息或者直接通信建立或修改请求信息携带的时间戳进行计算，从而提高第一终端设备的处理效率。
S403、第一终端设备根据端到端QoS信息以及第一QoS信息，获取第二QoS信息。
S404、第一终端设备向第三终端设备发送第二QoS信息。

在另一些情况下，若预先设置以第一终端设备指示的第一QoS信息为数据传输的QoS信息，则需要执行S405。且S405与S403的执行顺序可以不分先后。
例如，第一终端设备向第三终端设备发送第二QoS信息后，若第三终端设备无需更新第二QoS信息，在这样的情况下，第一终端设备也无需对第一QoS信息进行更新，则第一终端设备获取第一QoS信息之后，可将第一QoS信息发送至第二终端设备，因此，S405与S403的执行顺序可不分先后。
举例来说，若视频业务交互在第二终端设备与第三终端设备之间的端到端传输时延为200ms；视频业务在交互在第二终端设备与第一终端设备之间的传输时延为100ms，即第一QoS信息为100ms；视频业务交互在第一终端设备与第三终端设备之间的传输时延为100ms，即第二QoS信息为100ms；第三终端设备接收第一终端设备发送的第二QoS信息后，确定无需对第二QoS信息进行更新，则第二终端设备、第一终端设备以及第三终端设备根据上述第一QoS信息以及第二QoS信息进行视频业务数据的传输，从而保证视频业务数据在第二终端设备与第三终端设备之间的数据传输质量。
