图1是根据本申请实施例的通信方法100的示意性流程图。如图1所示，该通信方法100包括110、120、130和140。
在110中，发送端在发送包中加入时间指示信息，其中，该时间指示信息用于接收端获取该发送端到该接收端的时延。
可选地，该发送包为分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层包，无线链路控制(Radio Link Control，RLC)层包或媒体接入控制(Media Access Control，MAC)层包。
可选地，该发送包为数据包或为专用时延探测包。
在120中，该发送端向该接收端发送该发送包。
可选地，发送端确定需要获取从该发送端到该接收端的时延对应业务的服务质量(Quality of Service，QoS)，按照对应的服务质量QoS，该发送端向该接收端发送该发送包。
在130中，接收端接收发送端发送的发送包，其中，该发送包包括时间指示信息。
其中，接收端在解析时间标识信息时，是在发送端添加时间标识信息的相同层进行，例如，如果发送端在MAC层加入时间标识信息，则接收端在MAC层解析时间标识信息。
在140中，根据该时间指示信息，该接收端确定从该发送端到该接收端的时延。
可选地，在本申请实施例中，发送端可以通过多条路径发送该发送包，接收端接收该发送端通过多个路径发送的该发送包，确定该多个路径中的每个路径的时延。其中，发送包可以在该发送包中包含对应路径的路径信息，或者，发送包经过的中间节点在包中加入路径的路径信息。
可选地，在本申请实施例中，发送端发送的发送包中包括的时间指示信息可以包括该发送端处理该发送包的开始时间点，则接收端可以根据处理该发送包的结束时间点和该开始时间点之差，来确定从发送端到接收端的时延。其中，发送端处理该发送包的开始时间点是指得到该包的时间点或开始生成该包的时间点；接收端处理该发送包的结束时间点可以是指解析完该包的时间点。
可选地，上述开始时间点和结束时间点可以是绝对时间，例如，世界统一时间(Coordinated Universal Time，UTC)、北斗和GPS对应的绝对时间，则可以直接将结束时间点和开始时间点之差作为从发送端到接收端的时延。
上述开始时间点和结束时间点可以不是绝对时间，例如，可以是通信系统定义的时间，例如，由子帧或时隙表征的时间，则需要根据发送端与接收端的同步时间偏差，以及根据结束时间点和开始时间点之差，来确定从发送端到接收端的时延。
其中，发送端和接收端的同步时间偏差可以根据发送端到接收端的任意两个节点之间的同步时间偏差来计算。其中，中间节点的上一节点与该中间节点不同步时，该节点可以确定与上一节点的同步时间偏差，并在发送包中记录该同步时间偏差。
例如，发送端到接收端需要经过节点1和节点2，则节点1在接收到发送包之后，可以获取发送端与节点1的同步时间偏差，并记录在发送包中；节点2在接收到发送包之后，可以获取节点1与节点2之间的同步时间偏差，并记录在发送包中，其中，节点1和节点2之间的同步时间偏差可以与之前的同步时间偏差累加记录在发送包中，即将节点1和节点2之间的同步时间偏差与之前的同步时间偏差相加，并将记录的同步时间偏差更改为相加后的同步时间偏差，或者，节点1和节点2之间的同步时间偏差可以单独记录在一个信息字段中；接收端在接收到该发送包之后，可以获取节点2与接收端之间的同步时间偏差，并根据发送包的记录获取发送端与节点2的同步时间偏差，从而可以获取发送端与接收端之间的同步时间偏差。
可选地，发送端可以将处理该发送包的处理时延加入到发送包中，中间节点接收到发送包之后，可以将处理时延以及与上一节点之间的传输时延加入到发送包中，其中，中间节点可以将处理时延和传输时延单独记录在发送包中的不同信息字段中；或者，中间节点可以将本节点得到的处理时延和传输时延之和记录在信息字段中，但是不与其他节点记录的时间相累加；或者，中间节点可以将处理时延与其他节点得到处理时延累加记录在一个信息字段中，以及将传输时延与其他节点得到传输时延记录在另一个信息字段中；或者，中间节点将传输时延与处理时延之和与发送包记录的处理时延和传输时延之和相累加，并更新记录。发送端接收到发送包之后，可以根据发送包中的时间指示信息的指示来得到发送端与接收端之间的时延。
为了便于理解，以下以举例几种实现方式方法描述几种时间指示信息的记录方式。
在一种实现方式中，该时间指示信息包括该发送端处理该发送包的处理时延，以及包括从发送端到该接收端之间的任意中间节点处理该发送包的处理时延，以及包括任意中间节点获取的与上一节点之间的传输时延，其中，不同节点处理该发送包的处理时延承载在该发送包的不同信息字段中，不同节点获取的传输时延承载在该发送包的不同信息字段中，同一节点的处理时延和传输时延承载在该发送包的不同信息字段中。在这种情况下，接收端确定接收端处理该发送包的处理时延以及接收端与该接收端的上一节点的传输时延；根据该发送端处理该发送包的处理时延，任意中间节点处理该发送包的处理时延，任意中间节点获取的与其上一节点的传输时延，接收端处理该发送包的处理时延，接收端与该接收端的上一节点的传输时延五者之和，确定从该发送端到该接收端的时延。
例如，发送端到接收端需要经过节点1和节点2，发送端处理发送包的处理时延(例如1ms)记录在信息字段中，节点1接收到发送包，获取从接收端到节点1的传输时延0.5ms，以及获取处理该发送包的处理时延1ms，分别将0.5ms和1ms记录在不同的信息字段中；节点2接收到发送包，获取从节点1到节点2的传输时延0.6ms，以及获取处理该发送包的处理时延1.1ms，分别将该0.6ms和1.1ms记录在不同的信息字段中；接收端接收该发送包，获取从节点2到接收端的传输时延0.4ms和处理该发送包的处理时延1.2ms，并获取发送包中记录的1ms、1ms、0.5ms、0.6ms、1.1ms，将1ms、 1ms、0.5ms、0.6ms、1.1ms、0.4ms和1.2ms相加得到的时间值用于确定从发送端接收端的时延。
在一种实现方式中，该时间指示信息包括该发送端处理该发送包的处理时延，以及包括从发送端到该接收端的任意中间节点处理该发送包的处理时延与其与上一节点之间的传输时延之和；其中，不同节点处理该发送包的处理时延与获取的传输时延的之和承载在该发送包的不同信息字段中。在这种情况下，该接收端确定接收端处理该发送包的处理时延以及接收端与该接收端的上一节点的传输时延；根据该发送端处理该发送包的处理时延，从发送端到该接收端的上一节点的任意节点处理该发送包的处理时延与获取的与上一节点传输时延之和，接收端处理该发送包的处理时延，与接收端与该接收端的上一节点的传输时延四者之和，确定从该发送端到该接收端的时延。
例如，发送端到接收端需要经过节点1和节点2，发送端处理发送包的处理时延(例如1ms)记录在信息字段中，节点1接收到发送包，获取从接收端到节点1的传输时延0.5ms，以及获取处理该发送包的处理时延1ms，则将1.5ms记录在信息字段中；节点2接收到发送包，获取从节点1到节点2的传输时延0.6ms，以及获取处理该发送包的处理时延1.1ms，将1.7ms记录在与发送端不同的信息字段中；接收端接收该发送包，获取从节点2到接收端的传输时延0.4ms和处理该发送包的处理时延1.2ms，并获取发送包中记录的1ms、1.5ms和1.7ms，将1ms、1.5ms、1.7ms、0.4ms和1.2ms相加得到的时间值用于确定从发送端接收端的时延。
在一种实现方式中，该时间指示信息包括该发送端处理该发送包的处理时延、该发送端到该接收端之间的中间节点处理该发送包的处理时延和任意中间节点获取的与其上一节点的传输时延之和。该接收端确定该接收端处理该发送包的处理时延，以及从该接收端的上一节点到该接收端的传输时延；根据时间指示信息包括的该发送端处理该发送包的处理时延、该发送端到该接收端之间的中间节点处理该发送包的处理时延和任意中间节点获取的与其上一节点的传输时延之和，该接收端处理该发送包的处理时延，与从该接收端的上一节点到该接收端的传输时延三者之和，确定从该发送端到该接收端的时延。
例如，发送端到接收端需要经过节点1和节点2，发送端处理发送包的处理时延(例如1ms)记录在信息字段中，节点1接收到发送包，获取从接 收端到节点1的传输时延0.5ms，以及获取处理该发送包的处理时延1ms，则将发送端记录的1ms更新为2.5ms；节点2接收到发送包，获取从节点1到节点2的传输时延0.6ms，以及获取处理该发送包的处理时延1.1ms，则将节点1记录的2.5ms更新为4.2ms；接收端接收该发送包，获取从节点2到接收端的传输时延0.4ms和处理该发送包的处理时延1.2ms，并获取发送包中记录的14.2，将4.2、0.4ms和1.2ms相加得到的时间值用于确定从发送端接收端的时延。
如果各个节点获取的处理时延和/或传输时延不是通过绝对时间来得到的，则还需要获取发送端和接收端的同步时间偏差，其中，发送端和接收端的同步时间偏差可以根据发送端到接收端的任意两个节点之间的同步时间偏差来计算。其中，中间节点的上一节点与该中间节点不同步时，该节点可以确定与上一节点的同步时间偏差，并在发送包中记录该同步时间偏差。
其中，各个节点在发送包中记录与上一节点的同步时间偏差时，可以单独记录，也可以与处理时延和/或传输时延合并的方式记录。
可选地，该发送包还包括时延要求、接收端列表和反馈对象中的至少一种。
其中，在该发送包中包括时延要求时，接收端可以判断时延是否满足时延要求，并向反馈对象反馈从该发送端到该接收端的时延是否满足时延要求。
其中，在该发送包中不包括时延要求时，接收端可以直接向反馈对象从发送端到接收端的时延，或者根据其他方式获取的时延要求(例如，网络设备配置的时延要求)，接收端可以判断时延是否满足时延要求，并向反馈对象反馈从该发送端到该接收端的时延是否满足时延要求。
其中，时延的反馈对象可以是发送端也可以是第三方实体，比如网络设备。
可选地，该发送端接收第三方实体发送的配置信息，该配置信息用于指示该发送端向该接收端发送携带该时间指示信息的该发送包。
可选地，发送端通过Uu接口或终端直连接口向该接收端发送该发送包。
