具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。

扩展现实(Extended Reality，XR)是指通过计算机技术和可穿戴设备产生的一个真实与虚拟组合的、可人机交互的环境。
XR业务的特点是交互性、实时性，业务中的数据传输以下行视频为主，即到达用户终端设备的下行视频数据。当用户的动作、位置等信息经由上行链路传输至XR服务器后，XR服务器根据该信息生成视频帧，视频帧经过编码、压缩等处理后，经由下行链路发送至终端设备，再由终端设备向用户展示。
上述过程中，上行链路传输的用户动作、位置等信息由传感器等设备进行周期采样，数据具有周期性；下行链路传输的视频帧也具有周期性，以每秒60个视频帧为例，视频编码器每16.67ms会生成一个视频帧的对应的数据包，由于IP网络的最大数据包限制，通常一个视频帧被分成数十个至上百个IP数据包。对底层传输网络，即5G网络，体现为每16.67ms到达一个数据突发burst，一个burst包含多个数据包。
从接入网设备的角度而言，其无法识别上行数据包与下行数据包之间的关系，所以，接入网设备对上行传输和下行传输的传输时延、传输速率等信息分别进行统计，并优化。但是，从用户的角度而言，感受到的不是上行传输的时延，也不是下行传输的时延，而是上行传输时延、XR服务器处理时延、下行传输时延三者的总和。也就是说，用户只会感受到自己的动作变化后，经过多长时延，收到接入网设备的反馈信息。这三者中，XR服务器处理时延与传输网络无关，上行传输时延与下行传输时延与传输数据的接入网设备相关。如果接入网设备能对“上行传输时延+下行传输时延”统一进行优化，可以提高用户感受。
例如，图1为XR交互式业务的流程示意图，如图1所示，XR交互式业务中所涉及的对象包括传感器(Sensor)、XR客户端(XR Client)、终端设备、接入网设备(如基站gNB)、用户面功能(User Plane Function，UPF)单元以及XR服务器(XR Server)，其中，传感器、XR客户端、终端设备在物理形态上可以是一体或者分体，三者共享同一时钟。
参考图1，在实现XR业务的过程中，传感器定期生成用户的动作、位置等信息，XR Client定期向XR服务器传输包含用户动作、位置等信息的Pose数据包。其中，传感器生成信息的周期与XR Client传输信息的周期可以不同。通常，传感器生成信息的周期较短，如每秒1000次，而XR Client传输信息的周期较长，如每秒50次，也就是说，XR Client可以只选择一部分信息传输至XR服务器，即上述例子中，传感器每20次生成的信息中，可以只有一次生成的信息被XR Client选择传输至XR服务器。
例如，XR Client选择传感器在T1时刻采集的信息，将T1这一时戳信息包 含在Pose数据包中，依次经由终端设备、基站和UPF，传输至XR服务器，XR服务器读出Pose信息后，根据Pose信息生成对应的下行视频帧信息，将Pose数据包与下行视频帧一同打包成为下行数据，并进行初步处理，如渲染、加密、压缩等，再依次经由UPF、基站和终端设备传输至XR Client。XR Client在T2时刻收到下行数据包，经过解压缩、解密等处理，确定该下行视频帧是根据T1时刻的Pose数据生成的，再根据当前的时刻T2，对视频帧进行进一步渲染等处理，最终向用户呈现。
在图1所示的XR业务过程中，基站参与XR客户端、终端设备以及XR服务器之间的数据传输，但是只有XR Client和XR服务器知道XR业务数据的时间节点信息，即图1中的时刻T1和T2，而基站不知道这些信息。
因此，在XR客户端、终端设备的数量较多的情况下，基站可能出现调度不合理的情况，从而导致用户所感受到的时延较大，从而降低用户体验。
本申请提供的调度优化方法，旨在解决现有技术的如上技术问题。
本申请方案的主要构思为：终端设备在参与业务数据传输的过程中，可以将业务数据传输的往返时延上报给接入网设备，接入网设备在接收到终端设备上报的往返时延后，可以根据往返时延进行业务数据传输的调度优化，从而可以减少用户在业务过程中所感受到的时延，提高用户体验。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
图2为本申请实施例提供的调度优化方法的流程示意图，如图2所示，该方法主要包括以下步骤：
S201、终端设备获取与核心网设备进行数据传输的往返时延。
其中，往返时延(Round-Trip Time，RTT)表示从终端设备发送数据开始，到终端设备接收到来自核心网设备的反馈数据总共经历的时延。在XR业务中，RTT可以是指从终端设备将上行的包含用户动作、位置等信息的Pose数据包传输至核心网设备开始，到终端设备接收到核心网设备发送的下行视频帧数据的时延。
可以理解，本实施例的应用场景包括但不限于XR业务场景，也就是说，终端设备可以是被配置为针对某个特定的XR业务获取相应的RTT，以实现某个特定的XR业务调度优化；此外，终端设备也可以是被配置为针对所有的XR业务均 获取相应的RTT，以实现所有的XR业务的调度优化；另外，终端设备还可以是被配置为针对非XR业务获取相应的RTT，以实现非XR业务的调度优化。
在XR业务中，核心网设备可以是XR服务器。
S202、终端设备根据RTT，生成RTT信息。
可选的，终端设备可以在获取到数据传输过程中的RTT后，直接将RTT的数值作为RTT信息上报给接入网设备。
可选的，终端设备也可以是在获取到RTT后，先判断RTT是否满足预设条件，再确定是否生成上报给接入网设备的RTT信息，例如，若RTT不满足预设条件，则终端设备无需生成上报给接入网设备的RTT信息；若RTT满足预设条件，则终端设备生成上报给接入网设备的RTT信息。
S203、终端设备将RTT信息上报至接入网设备。
终端设备将RTT信息上报至接入网设备，对应的，接入网设备接收来自终端设备的RTT信息。
可选的，终端设备可以是周期性向接入网设备上报RTT信息，上报周期以及第一次上报时刻可以是由接入网设备进行配置；另外，终端设备也可以是非周期性向接入网设备上报RTT信息，即接入网设备可以配置多个终端设备上报RTT信息的不同时刻。
可选的，终端设备在上报RTT信息的时候，还可以上报推导出RTT信息的数据包的编号。例如，上行数据包的编号、下行数据包的编号。
S204、接入网设备根据RTT信息进行调度优化。
当接入网设备接收到来自终端设备的RTT信息后，根据该RTT信息，接入网设备可以知晓终端设备与核心网设备进行传输的时延信息，因此，接入网设备可以根据RTT信息进行调度优化，以减少终端设备与核心网设备进行传输的时延。
可选的，接入网设备根据RTT信息进行调度优化，包括：当确定RTT信息满足预设调度优化条件时，提高终端设备的调度优先级。例如，当接入网设备确定某个终端设备的RTT较大，通过提高该终端设备的调度优先级，可以起到降低终端设备的下行传输时延的目的。
本实施例提供一种调度优化方法，终端设备在参与业务数据传输的过程中，可以获取与核心网设备进行数据传输的RTT；根据RTT，生成RTT信息；将RTT信息上报给接入网设备，接入网设备在接收到终端设备上报的RTT信息后，可以根据RTT信息进行业务数据传输的调度优化，从而可以减少用户在业务过程 中所感受到的时延，提高用户体验。
在一些实施例中，对于终端设备在确定RTT满足预设条件后才生成需要上报至接入网设备的RTT信息的情况，RTT满足预设条件，包括以下任一项：
(1)RTT大于第一预设阈值，即当RTT的具体数值超出某个门限值时，终端设备才根据满足预设条件的RTT生成RTT信息；
(2)RTT小于第二预设阈值，即当RTT的具体数值低于某个门限值时，终端设备才根据满足预设条件的RTT生成RTT信息；
(3)RTT在第三预设范围内，即当RTT的具体数值位于某个门限值和另一个门限值之间的范围内时，终端设备才根据满足预设条件的RTT生成RTT信息；
(4)RTT平均值与前一次RTT平均值的差值大于第四预设阈值，即当终端设备获取的RTT平均值与前一次获取的RTT平均值的差值超出某个门限值时，终端设备才生成RTT信息；
其中，RTT平均值为最近一次获取的RTT与前N次获取的RTT的平均值，前一次RTT平均值为前N次获取的RTT的平均值，N为正整数。例如，终端设备一共获取了7次RTT，则RTT平均值为7次RTT的平均值，前一次RTT平均值为前6次RTT的平均值。
RTT的平均值可以采用普通平均或者加权平均计算得到。
可选的，当采用加权平均算法计算RTT平均值时，RTT的获取时间越接近当前时刻，RTT对应的权重越大。例如，最近获取的RTT对应的权重为a，之前获取的RTT对应的权重为b，则权重a和b的大小关系可以是a>b，比如a具体可以设定为0.7，b具体可以设定为0.3等。
(5)RTT平均值大于第五预设阈值，即当RTT平均值超出某个门限值时，终端设备才生成RTT信息；
(6)RTT平均值小于第六预设阈值，即当RTT平均值低于某个门限值时，终端设备才生成RTT信息；
(7)RTT平均值在第七预设范围内，即当RTT平均值位于某个门限值和另一个门限值之间的范围内时，终端设备才生成RTT信息。
(8)RTT与前一次RTT的差值大于第八预设阈值，即当终端设备最近一次获取的RTT与前一次获取的RTT的差值超出某个门限值时，终端设备才生成RTT信息。
可以理解，在上述各预设条件中，上述多个预设阈值和预设范围可以是由接入网设备进行配置。
在一些实施例中，生成RTT信息，具体包括：
在预设时间段内，生成RTT信息，即获取到RTT的时刻处于预设时间段内时，生成RTT信息。
其中，预设时间段可以是由接入网设备进行配置。具体的，终端设备可以是在接入网设备配置的预设时间段内，周期性生成RTT信息并上报或者条件性生成RTT信息并上报，而在预设时间段以外的时间，即使终端设备获取到RTT，终端设备也可以不生成RTT信息。
其中，预设时间段例如可以是某一个具体的时间范围，例如上午八点到九点、下午五点到六点等；预设时间段也可以通过无线帧标识来表示，例如采用系统帧号(System Frame Number，SFN)表示，比如当从SFN＝200到SFN＝300的时间段。
可选的，也可以在预设时间段外，生成RTT信息，即终端设备在获取到RTT的时刻处于预设时间段以外时，生成RTT信息并上报至接入网设备，即接入网设备配置终端设备在某一个预设时间段内，无需上报RTT信息，而在预设时间段以外的时间，终端设备周期性生成RTT信息并上报或者条件性生成RTT信息并上报。
在一些实施例中，终端设备生成RTT信息，具体包括：在接收到来自接入网设备的上报请求时，生成RTT信息并上报至接入网设备。
具体的，终端设备也可以被配置为只针对接入网设备的上报请求生成需要上报至接入网设备的RTT信息，即接入网设备向终端设备发送一次上报请求，终端设备则生成RTT信息并向接入网设备上报一次RTT信息。若终端设备未接收到接入网设备的上报请求，则可以不生成RTT信息。
在一些实施例中，终端设备上报至接入网设备的RTT信息包括以下至少一项：
(1)单次数据传输的RTT数值，即终端设备最近一次获取的RTT的具体值；
(2)目标时间段内RTT的平均值，即终端设备在目标时间段内获取的RTT的平均值，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
可选的，RTT平均值可以采用普通平均或者加权平均计算得到，当采用加权平均算法计算RTT平均值时，RTT的获取时间越接近当前时刻，RTT对应的权重越大。
(3)目标时间段内RTT大于第一预设阈值的次数，即终端设备在目标时间段内获取的RTT超出某个门限值的统计次数，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
(4)目标时间段内RTT大于第一预设阈值的次数与RTT总次数的比值，即终端设备在目标时间段内获取的RTT超出某个门限值的统计次数与获取RTT的总统计次数的比值，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
(5)目标时间段内RTT小于第二预设阈值的次数，即终端设备在目标时间段内获取的RTT低于某个门限值的统计次数，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
(6)终端设备在目标时间段内获取的RTT小于第二预设阈值的次数与获取RTT的总次数的比值，即终端设备在目标时间段内获取的RTT低于某个门限值的统计次数与获取RTT的总统计次数的比值，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
(7)目标时间段内RTT在第三预设范围内的次数，即终端设备在目标时间段内获取的RTT位于某个门限值和另一个门限值之间的范围内的统计次数，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
(8)目标时间段内RTT在第三预设范围内的次数与RTT总次数的比值，即终端设备在目标时间段内获取的RTT位于某个门限值和另一个门限值之间的范围内的统计次数与获取RTT的总统计次数的比值，其中，目标时间段可以是由接入网设备配置，目标时间段可以与上述的预设时间段相同，也可以是预设时间段之外的时间段。
可选的，对于接入网设备，其所执行的方法还包括：向终端设备发送配置信息，配置信息可以包括预设条件和预设时间段。
其中，预设条件用于指示终端设备上报RTT信息的条件，例如，预设条件可以是上述各个预设阈值和预设范围；预设时间段用于指示终端设备上报RTT信息的时间段，指示的时间段可以是目标时间段。
下面举例说明预设时间段与目标时间段之间的关系：
若接入网设备指示上报八点至二十点的RTT信息，则预设时间段与目标时间段均是八点至二十点；若接入网设备指示无需上报八点至二十点的RTT信息，则预设时间段为八点至二十点，目标时间段为零点至八点以及二十点至二十四点。
可选的，接入网设备还可以配置终端设备具体需要上报RTT信息的内容，终端设备根据内容生成RTT信息。
例如，接入网设备可以向终端设备发送进行统计预设时间段内RTT的次数，终端设备在完成该预设时间段的次数统计后，在向接入网设备上报相应的统计结果时，可以仅发送统计结果，即可以不发送相应的预设时间段，以减少信令开销。
可以理解，终端设备向接入网设备上报的RTT信息可以是包括以上任一项内容，也可以是包含上述多项内容，在此不做限定。
可选的，终端设备还可以向核心网设备上报RTT信息，上报的RTT信息可以是包括以上任一项内容，也可以是包含上述多项内容。
核心网设备可以是接入和移动管理功能(Access and Mobility Management Function,AMF)实体，也可以是核心网中的其他功能实体。
在一些实施例中，终端设备获取与核心网设备进行数据传输的RTT，包括：获取上行数据包的发送时刻，以及下行数据包的接收时刻；根据发送时刻以及接收时刻确定RTT。
可选的，终端设备根据发送时刻以及接收时刻确定RTT，包括：终端设备通过以下公式确定RTT：
RTT＝Td-Tu
其中，Tu表示上行数据包的发送时刻，Td表示下行数据包的接收时刻。
具体的，传感器、XR客户端、终端设备可以是合体设计或者分体设备，但是传感器、XR客户端、终端设备之间进行数据传输的时间极短，相比于5G网络的传输时延几乎可以忽略不计，因此，对于终端设备自身确定RTT的情况，XR客户端将获取上行的Pose数据包的时间通知终端设备，从而终端设备可以从XR客户端获取上行数据包发送时刻Tu；另外，当终端设备接收到核心网设备发送的下行数据包，终端设备也可以确定下行数据包接收时刻Td，进而可以根据Td和Tu确定RTT。
其中，由于下行数据包同时包含Pose数据包以及对应的下行视频帧，因此，终端设备可以根据下行数据包中的Pose数据包确定对应的上行数据包发送时刻 Tu，从而避免与其他数据包的发送时刻造成混淆。
在一些实施例中，终端设备获取与核心网设备进行数据传输的RTT，包括：终端设备接收来自业务客户端的RTT。
具体的，RTT也可以是由业务客户端(例如XR客户端)计算确定，并发送至终端设备。
以XR客户端为例，XR客户端可以直接获取Pose数据包对应的上行数据包发送时刻；另外，当下行数据包到达终端设备时，终端设备将下行数据包发送至XR客户端，从而，XR客户端也可以确定下行数据包接收时刻，进而可以确定RTT，并通知终端设备，还可以告知终端设备是根据哪一些数据包确定的RTT。
可选的，XR客户端通过以下公式确定RTT：
RTT＝Td-Tu
其中，Tu表示上行数据包发送时刻，Td表示下行数据包接收时刻。
其中，由于下行数据包同时包含Pose数据包以及对应的下行视频帧，因此，XR客户端可以根据下行数据包中的Pose数据包确定对应的上行数据包发送时刻，从而避免与其他数据包的发送时刻造成混淆。
应该理解的是，虽然上述实施例中的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。而且，图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
