具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
在下文中的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
首先，对本公开的应用场景进行说明。本公开可以应用于5G网络，相比于4G(The 4th Generation Mobile Communication Technology，第四代移动通信技术)网络，5G的一个非常重要的特性是数据传输中的超低时延，因此时延这一指标在衡量网络性能上的重要性显著提升。
3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)给出了用户面空口时延的定义，以及URLLC业务及eMBB业务的时延需求，包括：对于URLLC，用户面的目标时延应为UL(Upload Link，上行链路)为0.5ms，DL(Download Link，下行链路)为0.5ms；对于eMBB，UL的用户平面延迟目标为4ms，DL为4ms。用户面空口时延可以认为是应用层数据包自发送端的SDAP层发出，到接收端的SDAP层成功接收所花费的时延。
但是，相关技术中没有在无线网络中针对不同的业务类型进行业务层面的时延优化，这样，在PDCP层的丢弃时间配置不合理的情况下，可能会导致传输资源的浪费或者部分数据包被过早丢弃的问题，从而使得数据传输的效率较低。
为了解决上述问题，本公开提供一种调度终端设备的方法、装置、介质、 网络设备、终端及计算机程序产品，网络设备可以根据终端设备发送的第一处理时延和第二处理时延，调整该终端设备的调度优先级，之后，可以对调度优先级最高的终端设备进行调度，这样，根据优先级调整量调整后的目标调度优先级更加准确，使得网络设备根据该目标调度优先级调度终端设备时，可以避免调度优先级较高的数据包没有被及时调度而被过早丢弃，或者等待传输调度优先级较低的数据包过程中造成传输资源的浪费，从而可以提高数据传输的效率。
下面结合具体实施例对本公开进行说明。

在本步骤中，该第一处理时延和该第二处理时延可以是该终端设备预先获取的，在该终端设备向该网络设备发送业务请求消息时，可以在该业务请求消息中携带该第一处理时延和该第二处理时延。
S102、针对多个终端设备中的每个终端设备，根据该第一处理时延和该第二处理时延，获取该终端设备对应的优先级调整量，并根据该优先级调整量调整该终端设备的调度优先级，得到调整后的目标调度优先级。
其中，该调度优先级可以表征网络设备调度终端设备的顺序，该网络设备在调度终端设备时，可以按照该调度优先级从高至低的顺序调度终端设备。
在本步骤中，在接收到该终端设备发送的该第一处理时延和该第二处理 时延后，可以根据该第一处理时延和该第二处理时延获取该终端设备对应的优先级调整量。由于向该网络设备发送业务请求消息的终端设备可能有多个，因此，在获取每个终端设备对应的优先级调整量后，可以根据该优先级调整量调整所有终端设备的调度优先级，得到调整后的目标调度优先级。
S103、调度多个终端设备中，目标调度优先级最高的终端设备。
在本步骤中，在得到多个终端设备调整后的目标调度优先级后，可以调度该多个终端设备中目标调度优先级最高的终端设备。
采用上述方法，网络设备可以根据终端设备发送的第一处理时延和第二处理时延，调整该终端设备的调度优先级，之后，可以对调度优先级最高的终端设备进行调度，这样，根据优先级调整量调整后的目标调度优先级更加准确，使得网络设备根据该目标调度优先级调度终端设备时，可以避免调度优先级较高的数据包没有被及时调度而被过早丢弃，或者等待传输调度优先级较低的数据包过程中造成传输资源的浪费，从而可以提高数据传输的效率。
图2是本公开实施例提供的第二种调度终端设备的方法的流程图，该方法应用于终端设备。如图2所示，该方法包括：
S201、确定第一处理时延和第二处理时延。
其中，该第一处理时延可以包括数据包在终端侧的SDAP层的处理时延，该第二处理时延可以包括数据包从该终端侧的RLC层到PHY层的处理时延。
在本步骤中，在该终端设备向网络设备发送业务请求消息之前，可以预先确定该第一处理时延和该第二处理时延。其中，在确定该第一处理时延时，可以在数据包到达终端侧的SDAP层时开始计时，在完成该SDAP层的处理时结束计时，该计时时间段即为该第一处理时延，该第一处理时延可以表征该终端设备的处理能力。在确定该第一处理时延后，可以获取预先存储的该第二处理时延，该第二处理时延可以是预先配置的、在通信协议规定的时延范围内的时延，该第二处理时延可以预先存储在网管设备中，也可以预先存 储在该终端设备中，本公开对此不作限定。
S202、向网络设备发送该第一处理时延和该第二处理时延。
在本步骤中，在确定该第一处理时延和该第二处理时延后，可以在向该网络设备发送业务请求消息时，发送该第一处理时延和该第二处理时延。该网络设备在接收到该终端设备发送的该第一处理时延和该第二处理时延后，针对该多个终端设备中的每个终端设备，根据该第一处理时延和该第二处理时延，获取该终端设备对应的优先级调整量，并根据该优先级调整量调整该终端设备的调度优先级，得到调整后的目标调度优先级，并调度该多个终端设备中，目标调度优先级最高的终端设备。
采用上述方法，终端设备可以先确定数据包在终端侧的SDAP层的第一处理时延，以及数据包从该终端侧的RLC层到PHY层的第二处理时延，并向该网络设备发送该第一处理时延和该第二处理时延，该网络设备可以根据该终端设备发送的该第一处理时延和该第二处理时延，调整该终端设备的调度优先级，之后，可以对调度优先级最高的终端设备进行调度，这样，根据优先级调整量调整后的目标调度优先级更加准确，使得网络设备根据该目标调度优先级调度终端设备时，可以避免调度优先级较高的数据包没有被及时调度而被过早丢弃，或者等待传输调度优先级较低的数据包过程中造成传输资源的浪费，从而可以提高数据传输的效率。
图3是本公开实施例提供的第三种调度终端设备的方法的流程图。如图3所示，该方法包括：
S301、终端设备确定第一处理时延和第二处理时延。
其中，该第一处理时延可以包括数据包在终端侧的SDAP层的处理时延，该第二处理时延可以包括数据包从该终端侧的RLC层到PHY层的处理时延。图4是本公开实施例提供的一种数据传输示意图，如图4所示，左侧为终端侧对应的SPAD层至PHY层，右侧为网络侧对应的SPAD层至PHY层，终 端设备向网络设备发送数据包时，该数据包由终端侧的SPAD传输至PHY层，在PHY层处理完成后，将该数据包传输至网络侧的PHY层，通过网络侧的PHY层至SPAD层完成该数据包的处理。其中，t1为该第一处理时延，t3为该第二处理时延。
S302、终端设备向网络设备发送该第一处理时延和该第二处理时延。
S303、网络设备在接收到该终端设备发送的该第一处理时延和该第二处理时延后，根据该第一处理时延和该第二处理时延，获取该网络设备为该终端设备配置的PDCP层的传输丢弃时间阈值。
在本步骤中，网络设备在接收到该终端设备发送的该第一处理时延和该第二处理时延后，可以先获取该网络设备为该终端设备配置的PDCP层的传输丢弃时间阈值。其中，可以通过步骤S1～S4获取该传输丢弃时间阈值：
S1、获取数据传输时延，以及预先设置的第三处理时延。
其中，该数据传输时延可以包括该终端设备与该网络设备之间的传输时延，该数据传输时延与该终端设备和该网络设备之间的距离相关，该终端设备与该网络设备之间的距离越大，该数据传输时延越大，该终端设备与该网络设备之间的距离越小，该数据传输时延越小；该第三处理时延可以包括数据包从网络侧的PHY层到SDAP层的处理时延。如图4所示，t4为该数据传输时延，t5为该第三处理时延。
这里，获取该数据传输时延的方式包括多种，在一种可能的实现方式中，可以获取该网络设备为该终端设备配置的时间提前量，并根据该时间提前量确定该数据传输时延。其中，该网络设备可以通过相关技术的方式，根据该终端设备的位置计算得到该时间提前量，并将该时间提前量的二分之一作为该数据传输时延。
另外，该网络设备在接收到该终端设备发送的业务请求消息后，可以在网络侧的PHY层为该业务请求消息对应的数据包添加开始时间标签，在该 业务请求消息传输到该网络侧的SDAP层后再添加结束时间标签，该结束时间标签与该开始时间标签之间的时间间隔即为该第三处理时延。
需要说明的是，该网络设备在接收到该终端设备发送的业务请求消息后，也可以在该业务请求消息达到网络侧的PHY层时开始计时，在该网络侧的SDAP层完成该业务请求消息的处理后结束计时，该计时时间段即为该第三处理时延。
S2、获取该终端设备请求的业务连接在无线网络中的第四处理时延。
在一种可能的实现方式中，网络设备可以获取该终端设备请求的业务连接对应的时延需求，并获取核心网传输处理时延，将该时延需求与该核心网传输处理时延的差值，作为该第四处理时延。
其中，该业务连接对应的时延需求可以是在该终端设备发送的业务请求消息中携带的；也可以是该网络设备从核心网获取的，该时延需求可以是核心网根据该业务请求消息的类型确定的，不同的业务连接对应不同的时延需求，示例地，该网络设备可以从预先设置的业务质量配置中，获取该业务请求消息对应的时延需求。本公开还可以通过相关技术中的其它方式获取该终端设备请求的业务连接对应的时延需求，本公开对此不作限定。
进一步地，该网络设备在确定该终端设备请求的业务连接对应的时延需求后，可以向核心网发送时延获取请求，该时延获取请求用于获取该核心网处理该业务连接所需的核心网传输处理时延。之后，该网络设备可以获取该时延需求与该核心网传输处理时延之间的差值，将该差值作为该第四处理时延。
S3、获取该第一处理时延、该第二处理时延、该第三处理时延以及该数据传输时延的和值。
在该网络设备接收到该终端设备发送的该第一处理时延和该第二处理时延，并获取该第三处理时延和该第四处理时延后，可以获取该第一处理时 延、该第二处理时延、该第三处理时延以及该数据传输时延的和值。
S4、将该第四处理时延与该和值的差值，作为该传输丢弃时间阈值。
在该网络设备获取该第四处理时延，该第一处理时延、该第二处理时延、该第三处理时延以及该数据传输时延的和值后，可以获取第四处理时延与该和值的差值，并将该差值作为该传输丢弃时间阈值。
需要说明的是，该网络设备在获取该传输丢弃时间阈值后，可以向该终端设备发送该传输丢弃时间阈值，该终端设备在接收到该网络设备发送的该传输丢弃时间阈值后，可以确定待传输数据包在PDCP层的等待时间是否大于该传输丢弃时间阈值，并在确定该待传输数据包在该PDCP层的等待时间大于该传输丢弃时间阈值的情况下，丢弃该待传输数据包。
其中，该网络设备可以通过RRC(Radio Resource Control，无线资源控制)信令向该终端设备发送该传输丢弃时间阈值，也可以利用PDCCH(Physical Downlink Control Channel，物理下行控制信道)中的DCI(Downlink Control Information，下行控制信息)format x向该终端设备发送该传输丢弃时间阈值，还可以通过MAC CE向该终端设备发送该传输丢弃时间阈值，本公开对发送该传输丢弃时间阈值的方式不作限定。
该终端设备在接收到该网络设备发送的该传输丢弃时间阈值后，可以获取待传输数据包在PDCP层的传输等待时间，在该传输等待时间大于该传输丢弃时间的情况下，可以丢弃该待传输数据包。另外，该终端设备在丢弃该待传输数据包后，可以补充新的数据包作为待传输数据包。这样，可以根据业务连接的类型调整该传输丢弃时间阈值，避免因该传输丢弃时间阈值设置不合理，导致传输资源的浪费或者数据包被过早丢弃，从而可以提高数据传输的效率。
S304、网络设备获取数据包在终端侧的PDCP层的传输等待时延。
其中，该传输等待时延可以包括数据包在该PDCP层调度排队时产生的 时延。
在本步骤中，由于终端侧的PDCP层在处理完数据包后，将该数据包继续传输至终端侧的RLC层，以此类推，在终端侧处理完毕后，将该数据包传输至该网络设备，因此，该网络设备可以根据两次调度该终端设备的时间间隔，确定该传输等待时延，如图4所示，t2为该传输等待时延。
在一种可能的实现方式中，该网络设备可以获取接收到该第一处理时延的第一时刻，并获取上一次调度该终端设备的第二时刻，将该第一时刻和该第二时刻的时间间隔，作为该传输等待时延。其中，上一次调度该终端设备的第二时刻包括该终端设备上一次有数据包被该网络设备调度的时刻。该网络设备在接收到该终端设备发送的该第一处理时延后，可以记录当前时间，该当前时间即为该第一时刻，之后，可以获取上一次调度该终端设备的第二时刻，并将该第一时刻和该第二时刻的时间间隔作为该传输等待时延。
S305、网络设备根据该传输丢弃时间阈值和该传输等待时延，确定优先级调整量。
在本步骤中，该网络设备在获取该传输丢弃时间阈值和该传输等待时延后，可以按照公式(1)计算该优先级调整量：
P k＝∑T i/T k   (1)
其中，P k为第k个终端设备对应的优先级调整量，∑T i为多个终端设备对应的时延紧迫性表征的权值之和，T k为第k个终端设备对应的时延紧迫性表征的权值。
示例地，若终端设备包括10个，以该网络设备获取第3个终端设备对应的优先级调整量为例，则该网络设备可以先获取第1个终端设备对应的时延紧迫性表征的权值T 1，第2个终端设备对应的时延紧迫性表征的权值T 2，第3个终端设备对应的时延紧迫性表征的权值T 3，以此类推，获取第10个终端设备对应的时延紧迫性表征的权值T 10，之后，可以按照公式(1)计算 得到该第3个终端设备对应的优先级调整量P 3。其中，该时延紧迫性表示时延即将到期的紧迫性，示例地，距离时延到期时间越短，则时延紧迫性表征的权值越大，距离时延到期时间越长，则时延紧迫性表征的权值越小。
另外，可以按照公式(2)计算第k个终端设备对应的时延紧迫性表征的权值：
Figure PCTCN2021106345-appb-000001
其中，T k为第k个终端设备对应的时延紧迫性表征的权值，
Figure PCTCN2021106345-appb-000002
为第k个终端设备对应的传输等待时延，
Figure PCTCN2021106345-appb-000003
为第k个终端设备对应的传输丢弃时间阈值。
S306、网络设备根据该优先级调整量调整该终端设备的调度优先级，得到调整后的目标调度优先级。
在本步骤中，该网络设备在获取该多个终端设备中每个终端设备对应的优先级调整量后，可以将该优先级调整量作为该调度优先级的加权值，通过该加权值对该终端设备的调度优先级进行调整，得到调整后的目标调度优先级。示例地，在计算该终端设备的调度优先级时，可以将该优先级调整量叠加在调度优先级的计算公式中，这样，可以根据该终端设备的时延紧迫性对该终端设备的调度优先级进行调整，使得网络设备可以优先调度时延即将到期的终端设备，从而可以避免传输资源的浪费。
S307、网络设备调度多个终端设备中，目标调度优先级最高的终端设备。
采用上述方法，网络设备获取的传输丢弃时间阈值与该终端设备所请求的业务连接相关联，使得该网络设备可以结合业务层需求调整终端侧的PDCP层的传输丢弃时间阈值，避免传输资源的浪费或者数据包被过早丢弃。进一步地，该网络设备可以根据该传输丢弃时间阈值和该传输等待时延，确定优先级调整量，根据该优先级调整量调整该终端设备的调度优先级，得到调整后的目标调度优先级，并调度多个终端设备中，目标调度优先级最高的 终端设备。这样，该网络设备可以优先调度时延敏感的业务，使得时延敏感的业务能够更快地传输，从而可以提高数据传输的效率。
