本申请要求在2022年06月27日提交中国专利局、申请号为202210742647.6、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在移动通信系统(例如，第5代(the 5th generation，5G)通信系统)中，接入网(access network，AN)设备可根据固定周期的业务流特征，提供相应调度资源。例如，对于时间敏感通信中的业务，会话管理功能(session management function，SMF)可为AN设备提供时间敏感通信辅助信息(time sensitive communication assistant information，TSCAI)，AN设备根据TSCAI中的周期、到达时间等信息确定如何调度资源。
然而，垂直行业中业务流的传输周期可能是不固定的，如何为不固定周期的业务流确定无线资源，从而实现高效传输，是需要解决的技术问题。
发明内容
本申请提供一种通信方法及装置，用以为不固定周期的业务流确定资源。
第一方面，本申请实施例提供了一种通信方法。该方法包括：
AN设备在向第一通信设备发送AN设备的能力信息之后，可接收至少一个信息。其中，该能力信息可指示AN设备调度资源的最大时长。该至少一个信息中的任一信息包含用于指示时间范围的信息，该时间范围属于第一时间间隔的取值范围，且该时间范围对应的时长小于或等于该最大时长；第一时间间隔为第一业务流的每两个相邻数据突发之间的传输间隔。AN设备可根据该至少一个信息，确定用于传输第一业务流的数据突发的第一资源。
通过该方法，AN设备可向第一通信设备发送AN设备的能力信息，该能力信息可指示AN设备调度资源的最大时长；这样，第一通信设备可据此确定用于辅助调度的时间范围，AN设备根据该时间范围为不固定周期的业务流确定资源，可提高资源调度的效率。
在一种可能的设计中，AN设备的能力信息包括以下至少一项：
AN设备调度资源的最大时长；
AN设备的上下行配置信息，以及用于指示使用该上下行配置信息的资源对应的时长的信息。
通过该设计，AN设备可灵活指示AN设备调度资源的最大时长。
在一种可能的设计中，当第一时间间隔的取值范围对应的时长小于或等于AN设备调度资源的最大时长时，该至少一个信息包含的时间范围为该取值范围。此时，至少一个信 息可包括以下至少一项：
用于指示第一时间间隔的上限和下限的信息；
用于指示参考时长的信息，以及用于指示取值范围相对于参考时长的偏移的信息。
通过该设计，当第一时间间隔的取值范围对应的时长小于或等于AN设备调度资源的最大时长时，第一AN设备可调度与该取值范围对应的时域上连续的资源；此时，第一通信设备生成一个信息即可，从而可节省信令开销。
在一种可能的设计中，第一信息为至少一个信息中的任一信息，第一信息所指示的时间范围为第一时间范围，AN设备可根据第一时间范围和AN设备的上下行配置信息，确定用于传输第一业务流的数据突发的第一资源。其中，第一资源包括：至少一个第一传输资源；任一第一传输资源的时长与第一时间范围对应的时长相等，每两个相邻第一传输资源的中间资源之间的时间间隔为第一时间范围的中间值。
通过该设计，AN设备在调度资源时，不但考虑业务流的周期，还考虑上下行配置，从而可以合理的为第一业务流确定资源，提高资源调度的效率。
在一种可能的设计中，当未成功根据至少一个信息确定第一资源时，AN设备向会话管理网元发送第一指示；其中，该第一指示用于指示未成功根据至少一个信息确定第一资源。AN设备在接收来自会话管理网元的用于指示第二时间间隔的信息后，可根据第二时间间隔，确定用于传输第一业务流的数据突发的第二资源。
可选的，在向会话管理网元发送第一指示之前，AN设备可接收来自会话管理网元的第二指示。其中，第二指示用于指示AN设备在未成功根据至少一个信息确定第一资源时发送第一指示。
通过该设计，AN设备可向会话管理网元发送第一指示，该第一指示用于指示未成功根据至少一个信息确定第一资源，以便核心网设备对第一业务流进行整流，将第一业务流调整为在空口中按照固定周期传输的业务流；然后AN设备可根据固定周期确定资源，从而可实现不固定周期业务流的传输。
在一种可能的设计中，第二信息为至少一个信息中的任一信息，第一资源包括根据第二信息调度的至少一个第二传输资源。AN设备可在确定通过至少一个第二传输资源发送第一业务流的数据突发的时间偏移值后，向会话管理网元发送用于指示时间偏移值的信息。其中，时间偏移值用于表示第二通信设备能够根据至少一个第二传输资源发送第一业务流的数据突发的时刻与准备发送第一业务流的数据突发的时刻之间的差值。
通过该设计，AN设备可向会话管理网元发送用于指示时间偏移值的信息，以便核心网设备据此对第一业务流的传输进行优化。例如，若时间偏移值较大，导致第一业务流的数据突发的传输时延较大，则核心网设备可重新生成至少一个信息，以便AN设备据此重新确定用于传输第一业务流的数据突发的资源，从而有可能减小该时间偏移值，进而可能减小第一业务流的数据突发的传输时延。
第二方面，本申请实施例提供了一种通信方法。该方法包括：
第一通信设备接收AN设备的能力信息；其中，该能力信息用于指示AN设备调度资源的最大时长。第一通信设备接收来自应用功能网元的用于指示第一时间间隔的取值范围的信息。其中，第一时间间隔为第一业务流的每两个相邻数据突发之间的传输间隔。用于指示第一时间间隔的取值范围的信息可包括：用于指示第一时间间隔的上限和下限的信息； 和/或，用于指示参考时长的信息，以及用于指示取值范围相对于参考时长的偏移的信息。然后，第一通信设备可在根据第一时间间隔的取值范围和AN设备的能力信息，生成至少一个信息后，向AN设备发送至少一个信息。其中，该至少一个信息中的任一信息用于指示属于该取值范围内的时间范围，该时间范围对应的时长小于或等于AN设备调度资源的最大时长。
通过该方法，对于不固定周期的业务流，第一通信设备可根据不固定周期的取值范围和AN设备的能力信息，生成至少一个信息，该至少一个信息中的任一信息可指示属于该取值范围内的时间范围，该时间范围对应的时长小于或等于AN设备调度资源的最大时长。由于该至少一个信息中的任一信息指示的时间范围小于或等于该最大时长，AN设备具有调度与该时间范围对应的资源的能力；因此，AN设备可根据该至少一个信息中的时间范围为不固定周期的业务流确定资源，从而提高资源调度的效率。
在一种可能的设计中，AN设备的能力信息包括以下至少一项：
AN设备调度资源的最大时长；
AN设备的上下行配置信息，以及用于指示使用该上下行配置信息的资源对应的时长的信息。
通过该设计，AN设备可灵活指示AN设备调度资源的最大时长。
在一种可能的设计中，当第一时间间隔的取值范围对应的时长小于或等于AN设备调度资源的最大时长时，至少一个信息中包含的时间范围为该取值范围。
通过该设计，当第一时间间隔的取值范围对应的时长小于或等于AN设备调度资源的最大时长时，第一AN设备可调度与该取值范围对应的时域上连续的资源；此时，第一通信设备生成一个信息即可，从而可节省信令开销。
在一种可能的设计中，在向AN设备发送至少一个信息之后，第一通信设备可接收用于指示时间偏移值的信息。其中，时间偏移值用于表示第二通信设备能够发送第一业务流的数据突发的时刻与准备发送第一业务流的数据突发的时刻之间的差值。当该时间偏移值大于或等于第一阈值时，第一通信设备可重新生成至少一个信息。
通过该设计，当通过AN设备调度的资源来传输第一业务流的数据突发时，若时间偏移值较大，导致第一业务流的数据突发的传输时延较大，则可重新生成至少一个信息，以便AN设备据此重新确定用于传输第一业务流的数据突发的资源，从而有可能减小该时间偏移值，进而可能减小第一业务流的数据突发的传输时延。
第三方面，本申请实施例提供了一种通信方法。该方法包括：
应用功能网元向第一通信设备发送用于指示第一时间间隔的取值范围的信息。其中，第一时间间隔为第一业务流的每两个相邻数据突发之间的传输间隔。用于指示第一时间间隔的取值范围的信息包括：用于指示第一时间间隔的上限和下限的信息；和/或，用于指示参考时长的信息，以及用于指示取值范围相对于参考时长的偏移的信息。应用功能网元在接收到用于指示期望传输第一业务流的数据突发的时间的信息之后，可根据期望传输第一业务流的数据突发的时间，发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发。
通过该方法，应用功能网元可根据期望传输第一业务流的数据突发的时间，发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发，使得第一业务 流的每个数据突发到达空口的时刻都属于期望传输第一业务流的数据突发的时间，从而减小第一业务流的数据突发的传输时延。
在一种可能的设计中，应用功能网元可根据期望传输第一业务流的数据突发的时间，以及第一业务流中每两个相邻数据突发之间的传输间隔，发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发。通过该设计，应用功能网元在发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发时，不但考虑期望传输第一业务流的数据突发的时间，还考虑第一业务流中每两个相邻数据突发之间的传输间隔，从而可尽量降低第一业务流中每个数据突发的传输时延。
在一种可能的设计中，期望传输第一业务流的数据突发的时间包括：期望传输第一业务流的数据突发的至少一个时间范围，或期望传输第一业务流的数据突发的至少一个时刻。该设计提供了多种期望传输第一业务流的数据突发的时间的表现形式，可应用于不同的场景，实现较为简单。

通过本申请实施例提供的方案，AN设备可向第一通信设备发送AN设备的能力信息，该能力信息可用于指示AN设备调度资源的最大时长。第一通信设备可根据第一业务流的不固定周期的取值范围(即本申请中第一时间间隔的取值范围)和最大时长之间的关系，判断是否需要对第一业务流的周期范围进行拆分。当不固定周期的取值范围对应的时长大于最大时长时，第一通信设备将不固定周期的取值范围拆分成多个时间范围，每个时间范围对应的时长小于或等于最大时长。然后，第一通信设备可向AN设备发送用于辅助调度的至少一个信息，每个信息包含一个时间范围。AN设备根据该至少一个信息为第一业务流调度资源。通过该方案，对于不固定周期的业务流，第一通信设备可根据不固定周期的取值范围和AN设备的能力信息，生成至少一个信息，该至少一个信息中的任一信息可指示属于该取值范围内的时间范围，该时间范围对应的时长小于或等于最大时长；由于该至少一个信息中的任一信息指示的时间范围小于或等于最大时长，AN设备具有调度与该时间范围对应的资源的能力，因此，AN设备可根据该至少一个信息中的时间范围为不固定周期的业务流确定资源，可提高资源调度的效率。

为便于理解本申请方案，下面对相关背景技术进行介绍说明。
一、空口调度机制
1、传统的上行调度原理：当需要发送上行数据时，终端设备在物理上行控制信道(physical uplink control channel，PUCCH)上发送调度请求(scheduling request，SR)。AN 设备在接收到SR之后，可向终端设备发送上行授权。终端设备可在上行授权指示的位置(即上行授权所指示的时频资源)发送上行数据。
在传统的上行调度流程中，终端设备只能根据配置周期性发送SR；根据协议，SR的发送周期最大可达80毫秒(ms)。因此，通过该流程进行上行数据传输，时延可能较大。
2、上行预调度原理：
为了降低上行时延，引入了上行预调度功能。在上行预调度流程中，AN设备可对终端设备进行主动授权；也就是说，AN设备可为终端设备预先配置上行资源，而不需要等待接收到来自终端设备的SR之后再进行上行授权。在上行预调度流程下，即使终端设备不需要发送上行数据，AN设备也会主动给终端设备进行主动授权，因此，可能会造成上行资源的浪费；并且，AN设备可能为多个终端设备预配置相同的上行资源，从而会引入上行干扰。
3、智能预配置原理：
为了避免上行资源的浪费和上行干扰，引入了智能预调度功能。该功能可由下行业务触发。具体的，在AN设备向终端设备发送下行数据之后，考虑到终端设备会对该下行数据进行相应的反馈，从而产生上行数据，AN设备可在发送下行数据之后的一定时间内主动给终端进行上行授权，分配上行资源。
4、上行免调度(grant free，也称为免授权调度)原理：
对于物理上行共享信道(physical uplink shared channel，PUSCH)，第三代合作伙伴计划(3rd generation partnership project，3GPP)协议(例如，版本15(release 15，R15)协议)支持免授权调度。AN设备可以周期性的为终端设备分配免授权上行资源；这样，当终端设备需要发送上行数据时，可通过免授权上行资源发送上行数据，从而可减少上行数据的传输时延。具体的，AN设备可以向终端设备发送用于配置上行免调度资源的第一无线资源控制(radio resource control，RRC)信令；然后，AN设备可通过向终端设备发送第二RRC信令或下行控制信息(downlink control information，DCI)来激活配置的上行免调度资源。在上行免调度资源被激活后，终端设备可在上行免调度资源上直接发送上行数据，而无需先向AN设备发送SR或缓冲状态报告(buffer status report，BSR)，且在收到AN设备发送的上行授权之后，才能发送上行数据，从而可以达到缩短时延的目的。
5、下行调度基本流程：
AN设备根据终端设备上报的信道状态，结合UE能力等信息，为终端设备分配下行资源，并通过物理下行控制信道(physical downlink control channel，PDCCH)向终端设备发送用于指示分配的下行资源的调度信息。AN设备可在分配给终端设备的下行资源上向终端设备发送下行数据；终端设备根据从PDCCH信道接收到的调度信息确定分配的下行资源，在该下行资源上接收下行数据并进行解调。
6、下行半持续调度原理：
AN设备可向终端设备发送用于配置周期性的下行资源的第三RRC信令，并通过向终端设备发送使用配置调度无线网络临时标识(radio network temporary identifier，RNTI)(configured scheduling RNTI，CS-RNTI)标识的PDCCH来激活该周期性的下行资源。其中，该CS-RNTI标识的PDCCH上可承载调度该周期性的下行资源所需的信息，并指示该下行资源可以根据无线连接控制(radio resource control，RRC)(例如，第三RRC信令)所定义的周期性来进行复用。另外，所配置的下行资源也可以由CS-RNTI标识的PDCCH 来进行去激活，也就是说，AN设备可通过向终端设备发送使用CS-RNTI标识的PDCCH来去激活该周期性的下行资源。
二、空口调度流程
1、应用于图1C所示架构中的空口调度流程。该流程包括步骤A1-A6。
A1：AF通过NEF向TSCTSF发送业务流的特征信息。
其中，业务流可为TSC流。业务流的特征信息可包括以下至少一项：该业务流的数据突发的传输周期，该业务流的传输方向(即该业务流的流方向)，以及该业务流的突发到达时间。其中，每个数据突发可包括一个或多个业务数据包。传输周期为该业务流的每两个相邻数据突发之间的时间间隔。
A2：TSCTSF根据业务流的特征信息，生成TSCAC。其中，TSCAC包含上述特征信息。TSCAC的具体内容可参见表1。
表1
A3：TSCTSF通过PCF向SMF发送TSCAC。该TSCAC可用于IP类型或以太网类型的PDU会话。
可选的，PCF在接收到TSCAC后，可将其作为策略控制和计费(Policy Control and Charging，PCC)规则的一部分转发给SMF。
A4：SMF将包含TSCAC的PCC规则与QoS流绑定，并根据TSCAC为该QoS流推导TSCAI。其中，TSCAI包含上述传输周期。TSCAI的具体内容可参见表2。
表2
A5：SMF将推导的TSCAI发送给AN设备。
A6：AN设备根据TSCAI调度资源。
其中，AN设备可根据TSCAI进行上行免授权调度或下行半持续调度。AN设备调度的资源可包括多个传输资源，该多个传输资源中每两个相邻传输资源之间的间隔为TACAI中的周期。
2、应用于图1B所示的架构中的空口调度流程。该流程包括步骤B1-B5。
B1：TSN AF根据业务流的特征信息，生成TSCAC。其中，TSCAC包含业务流的特征信息中的传输周期。TSCAC的具体内容可参见表1。
B2：TSN AF通过PCF向SMF发送TSCAC。
可选的，PCF在接收到TSCAC后，可将其作为PCC规则的一部分转发给SMF。
B3：SMF将包含TSCAC的PCC规则与QoS流绑定，并根据TSCAC为该QoS流推导TSCAI。
其中，TSCAI包含上述传输周期。TSCAI的具体内容可参见表2。
B4：SMF将推导的TSCAI发送给AN设备。
B5：AN设备根据TSCAI调度资源。
B5的具体内容可参考A6，此处不再赘述。
通过1和2中的流程，SMF可为AN设备提供TSCAI。该TSCAI与QoS流对应，可用于提供辅助信息来描述QoS流的特征。其中，该QoS流的传输方向可为下行方向和/或上行方向。这样，AN设备可根据TSCAI中的周期参数，通过配置授权、半静态调度或动态授权更有效地为具有固定周期的业务流调度资源。
3、不固定周期(或称为周期可变)的业务流。
目前，有些业务流(例如，TSC流)的传输周期并不是固定的。例如，在垂直领域的如下场景中，业务流的传输周期可能是不固定的，即业务流的每两个相邻数据突发之间的传输间隔(Transfer interval)可能是不固定的：
(1)移动机器人(例如，用于视频操作遥控器的移动机器人)；
(2)用于远程控制装配机器人或铣床的移动控制面板(传输周期为4～8ms)；
(3)用于移动起重机、移动泵或固定门式起重机的远程控制的移动控制面板；
(4)工厂资产管理；
(5)用于闭环控制的过程自动化。
其中，场景(1)-(4)中，业务流的每两个相邻数据突发之间的传输间隔可能存在±25％的偏离；场景(5)中，业务流的每两个相邻数据突发之间的传输间隔可能存在±5％的偏离。
需要说明的是，上述TSC流具有周期在一定范围内波动的特点，但上述场景属于3GPP定义的周期性确定性通信。
如何为不固定周期的业务流确定调度资源，是本申请要解决的问题。
下面结合附图对本申请提供的方案进行说明。
本申请实施例提供了一种通信方法，该方法可应用于图1A-图1C所示的通信系统中。下面参阅图2所示的流程图，以会话管理网元为SMF，应用功能网元为AF为例，对该方法的流程进行具体说明。
S201：AN设备向第一通信设备发送AN设备的能力信息。其中，能力信息可用于指示AN设备调度资源的最大时长；换句话说，该能力信息可用于指示AN设备能够调度的时域上连续的资源的最大时长。相应的，第一通信设备接收来自AN设备的AN设备的能力信息。
其中，第一通信设备可为SMF、TSCTSF或TSN AF。当第一通信设备为TSCTSF或TSN AF时，AN设备可通过SMF向TSCTSF或TSN AF发送AN设备的能力信息。可选 的，SMF可在解析来自AN设备的AN设备的能力信息后，向第一通信设备发送AN设备的能力信息；也可以直接透传AN设备的能力信息。
可选的，该最大时长可包括：AN设备调度的连续上行资源的最大时长，和/或AN设备调度的连续下行资源的最大时长。
AN设备调度的连续上行资源可为AN设备在主小区调度的连续上行资源，也可以为AN设备在所有小区调度的连续上行资源。例如，当AN设备调度的连续上行资源为AN设备在所有小区调度的连续上行资源时，若AN设备在主小区调度的上行资源为时隙1和时隙2对应的资源，AN设备在辅小区调度的上行资源为时隙3和时隙6对应的资源，则AN设备调度的连续上行资源为时隙1-时隙3对应的资源。
AN设备调度的连续下行资源可为AN设备在主小区调度的连续下行资源，也可以为AN设备在所有小区调度的连续下行资源。例如，当AN设备调度的连续下行资源为AN设备在所有小区调度的连续下行资源时，若AN设备在主小区调度的下行资源为时隙7和时隙8对应的资源，AN设备在辅小区调度的下行资源为时隙4和时隙9对应的资源，则AN设备调度的连续下行资源为时隙7-时隙9对应的资源。
可选的，AN设备的能力信息包括以下至少一项：
1、AN设备调度资源的最大时长。
在一些可能的方式中，该能力信息可直接指示AN设备调度的连续资源的最大时长。例如，该能力信息为：上行1毫秒(ms)，表示AN设备调度的连续上行资源的最大时长为1ms。又例如，该能力信息为：下行2ms，表示AN设备调度的连续下行资源的最大时长为2ms。
在另一些可能的方式中，该能力信息还可间接指示AN设备调度的连续资源的最大时长。例如，该能力信息的第一字段的取值为第一值时，表示AN设备调度的连续上行资源的最大时长为1ms。又例如，该能力信息的第二字段的取值为第二值时，表示AN设备调度的连续下行资源的最大时长为2ms。
2、AN设备的上下行配置信息以及用于指示使用该上下行配置信息的资源对应的时长的信息。
在一些可能的方式中，该上下行配置信息可直接指示AN设备的上下行配置。例如，该上下行配置信息为：UUDDDUUDDD，其中，U代表上行时隙，D代表下行时隙；使用该上下行配置信息的无线帧对应的时长为10ms，此处以子载波间隔(sub-carrier space，SCS)＝30千赫兹(KHz)为例，1个无线帧＝20时隙，即每个时隙为0.5ms；这样，AN设备调度的连续上行资源的最大时长为1ms，AN设备调度的连续下行资源的最大时长为1.5ms。也可以以其他SCS为例，相应每个时隙时长不同，可能为1ms，0.5ms，0.25ms，0.125ms等，不一一列举。
在另一些可能的方式中，该上下行配置信息可间接指示AN设备的上下行配置。例如，当上下行配置信息为第三值时，对应的上下行配置为UUDDDUUDDD。
此外，用于指示使用该上下行配置信息的资源对应的时长的信息可直接指示该时长，也可以间接指示该时长，本申请对此不作限定。
在S201中，AN设备的能力信息可以承载在现有的消息(例如，注册请求)中，也可以承载在新的消息中，本申请对此不作限定。
S202：AF向第一通信设备发送用于指示第一时间间隔的取值范围的信息。相应的， 第一通信设备接收来自AF的用于指示第一时间间隔的取值范围的信息。
当第一通信设备为TSCTSF或TSN AF时，AF可直接向TSCTSF或TSN AF发送用于指示第一时间间隔的取值范围的信息，也可以通过NEF向TSCTSF或TSN AF发送用于指示第一时间间隔的取值范围的信息。当第一通信设备为SMF时，AF可通过TSCTSF或TSN AF向SMF发送用于指示第一时间间隔的取值范围的信息。其中，用于指示第一时间间隔的取值范围的信息可承载在现有的消息(例如，QoS和TSC辅助创建消息(Ntsctsf_QoSandTSCAssistance_Create)、PCF策略授权更新请求和会话管理(session management，SM)策略控制更新等中至少一项)中，也可以承载在新的消息中，本申请对此不作限定。
其中，第一时间间隔为第一业务流的每两个相邻数据突发之间的传输间隔；换句话说，第一时间间隔为第一业务流的传输周期。这样，第一时间间隔的取值范围即为第一业务流的传输周期的取值范围；也就是说，第一业务流的传输周期为不固定周期或可变周期。另外，第一业务流可为TSC流。
可选的，用于指示第一时间间隔的取值范围的信息可包括以下至少一项：
1、用于指示第一时间间隔的上限和下限的信息。例如，第一时间间隔的上限为5ms，第一时间间隔的下限为3ms，表示第一时间间隔的取值范围为3ms-5ms。
2、用于指示参考时长的信息，以及用于指示取值范围相对于参考时长的偏移的信息。其中，取值范围相对于参考时长的偏移可以为绝对值，也可以为相对值。例如，参考时长为4ms，取值范围相对于参考时长的偏移为±1ms，表示第一时间间隔的取值范围为3ms-5ms。又例如，参考时长为4ms，取值范围相对于参考时长的偏移为±25％，表示第一时间间隔的取值范围为3ms-5ms。
通过该方法，可以灵活指示第一时间间隔的取值范围，即第一业务流的周期范围。
可选的，在S202中，AF还可向第一通信设备发送用于指示第一业务流的传输方向的信息，从而指示第一业务流的传输方向是上行方向还是下行方向。其中，用于指示第一业务流的传输方向的信息和用于指示第一时间间隔的取值范围的信息可以携带在相同的消息中，也可以携带在不同的消息中。
此外，本申请对S201和S202的执行顺序不做限定。
S203：第一通信设备根据第一时间间隔的取值范围和AN设备的能力信息，生成至少一个信息。其中，该能力信息用于指示AN设备调度资源的最大时长，具体内容可参考S201；至少一个信息中的任一信息可用于指示属于第一时间间隔的取值范围内的时间范围，该时间范围对应的时长小于或等于AN设备调度资源的最大时长。
其中，至少一个信息可为至少一个TSCAC，该时间范围为TSCAC中周期参数指示的范围；或者，至少一个信息可为至少一个TSCAI，该时间范围为TSCAI中周期参数指示的范围。
在一些可能的方式中，当第一时间间隔的取值范围对应的时长小于或等于AN设备调度资源的最大时长时，该时间范围为第一时间间隔的取值范围。例如，第一时间间隔的取值范围为3ms-5ms，该取值范围对应的时长为2ms；若最大时长为2ms，则至少一个信息为一个信息，该一个信息指示的时间范围为3ms-5ms。应理解，当第一时间间隔的取值范围对应的时长小于或等于最大时长时，第一AN设备可调度与该取值范围对应的时域上连续的资源；此时，第一通信设备生成一个信息即可，从而可节省信令开销。
在另一些可能的方式中，当第一时间间隔的取值范围对应的时长大于AN设备调度资源的最大时长时，至少一个信息所指示的时间范围的并集为第一时间间隔的取值范围。例如，第一时间间隔的取值范围为3ms-5ms，该取值范围对应的时长为2ms；若最大时长为1ms，则至少一个信息可包含信息1和信息2，信息1指示的时间范围为3ms-4ms；信息2指示的时间范围为4ms-5ms。通过该方法，当第一时间间隔的取值范围对应的时长大于最大时长时，第一通信设备可将第一时间间隔的取值范围拆成多个时间范围，并针对每个时间范围生成一个与AN设备的调度能力相适应的信息，从而得到多个信息，使得AN设备可根据该多个信息成功调度资源。
可选的，第一通信设备在生成至少一个信息时还可考虑第一业务流的传输方向，根据第一业务流的传输方向、第一时间间隔的取值范围和与该传输方向对应的最大时长，生成至少一个信息。
在一些可能的方式中，当第一时间间隔的取值范围对应的时长小于或等于第一业务流的传输方向对应的AN设备调度资源的最大时长时，该时间范围为第一时间间隔的取值范围。例如，第一业务流的传输方向为下行方向；第一时间间隔的取值范围为3ms-5ms，该取值范围对应的时长为2ms；AN设备在下行方向的最大时长为2ms。此时，至少一个信息可为一个信息，该一个信息指示的时间范围为3ms-5ms。
在另一些可能的方式中，当第一时间间隔的取值范围对应的时长大于第一业务流的传输方向对应的AN设备调度资源的最大时长时，至少一个信息所指示的时间范围的并集为第一时间间隔的取值范围。例如，第一业务流的传输方向为上行方向；第一时间间隔的取值范围为3ms-5ms，该取值范围对应的时长为2ms；AN设备在上行方向的最大时长为1ms，则至少一个信息可包含信息1和信息2，信息1指示的时间范围为3ms-4ms；信息2指示的时间范围为4ms-5ms。
S204：第一通信设备向AN设备发送上述至少一个信息。相应的，AN设备接收来自第一通信设备的该至少一个信息。
当第一通信设备为TSCTSF或TSN AF时，TSCTSF或TSN AF可通过SMF向AN设备发送上述至少一个信息。示例性的，TSCTSF或TSN AF可通过以下方式之一来向通过SMF向AN设备发送上述至少一个信息。
在一些可能的方式中，TSCTSF或TSN AF向SMF发送上述至少一个信息，SMF将接收到的至少一个信息转发给AN设备。
在另一些可能的方式中，TSCTSF或TSN AF向SMF发送上述至少一个信息之后，SMF获取与上述至少一个信息一一对应的一个或多个信息，该一个或多个信息中的任一信息所指示的时间范围与上述至少一个信息中对应的信息所指示的时间范围相同。例如，上述至少一个信息为至少一个TSCAC；该一个或多个信息为一个或多个TSCAI；任一TSCAI所指示的时间范围与对应的TSCAC所指示的时间范围相同。
其中，第一通信设备可通过现有的消息(例如，PCF策略授权更新请求和SM策略控制更新和/或会话修改流程中的消息)向AN设备发送上述至少一个信息，也可以通过新的消息向AN设备发送上述至少一个信息。
当第一通信设备为SMF时，SMF可通过现有的消息(例如，会话修改流程中的消息)向AN设备发送上述至少一个信息，也可以通过新的消息向AN设备发送上述至少一个信息。
S205：AN设备根据该至少一个信息，确定用于传输第一业务流的数据突发的第一资源。
下面以该至少一个信息为第一信息为例，对S205进行说明。
第一信息为该至少一个信息中的任一信息，第一信息所指示的时间范围为第一时间范围。第一资源包括：至少一个第一传输资源；任一第一传输资源的时长与第一时间范围对应的时长相等，每两个相邻第一传输资源的中间资源之间的时间间隔为第一时间范围的中间值。也就是说，AN设备可调度与时间范围对应的时间窗内的资源作为第一资源。例如，第一信息所指示的时间范围为3ms-5ms，AN设备确定的第一资源可包括：3ms-5ms处的资源、(3+4*n)ms-(5+4*n)ms处的资源。其中，n为正整数。
可选的，以第一信息为例，AN设备还可根据第一时间范围和AN设备的上下行配置信息，确定用于传输第一业务流的数据突发的第一资源。例如，第一信息所指示的时间范围为2ms-3ms，AN设备的上下行配置为UUDDDUUDDD，第一业务流的传输方向为上行，AN设备确定的第一资源可包括：0ms-1ms处的上行资源、(0+2.5*o)ms-(1+2.5*o)ms处的上行资源。其中，o为正整数。又例如，第一信息所指示的时间范围为2ms-3ms，AN设备的上下行配置为UUDDDUUDDD，第一业务流的传输方向为下行，AN设备确定的第一资源可包括：1ms-2ms处的下行资源、(1+2.5*m)ms-(2+2.5*m)ms处的下行资源。其中，m为正整数。通过该方法，AN设备在调度资源时，不但考虑业务流的周期，还考虑上下行配置，从而可以合理的为第一业务流确定资源，提高资源调度的效率。
此外，以第一信息为例，AN设备还可根据第一时间范围和第一业务流的数据突发的到达时间，确定用于传输第一业务流的数据突发的第一资源。例如，第一业务流的数据突发到达第二通信设备的时刻为x ms，第一时间范围占用的时长为2ms，第一资源包括：x ms-(x+2)ms处的资源、(x+T*p)ms-(x+T*p)ms处的资源。其中，T为第一时间范围的平均值，例如，第一时间范围为3ms-5ms时，T为4；p为正整数，x为非负数。通过该方法，AN设备在调度资源时，不但考虑业务流的周期，数据突发的到达时间，从而可以降低数据突发的传输时延。
可选的，若在S205中AN设备未成功根据至少一个信息确定第一资源，该方法还包括步骤C1-C4：
C1：AN设备可向SMF发送第一指示，第一指示用于指示未成功根据至少一个信息确定第一资源。
其中，第一指示可以是消息，也可以是消息中的信元。具体地，当第一指示为信元时，第一指示可以复用现有消息中的信元，也可以是现有消息中的新的信元。例如，所述信元可以为第四字段，当该字段取值为第四值时，可以指示未成功根据至少一个信息确定第一资源。
可选的，在步骤C1之前，SMF可向AN设备发送第二指示，相应的，AN设备可接收来自SMF的第二指示。其中，第二指示可用于指示AN设备在未成功根据至少一个信息确定第一资源时发送第一指示。
其中，第二指示可以是消息，也可以是消息中的信元。具体地，当第二指示为信元时，第二指示可以复用现有消息中的信元，也可以是现有消息中的新的信元。例如，所述信元可以为第五字段，当该字段取值为第五值时，可以指示AN设备在未成功根据至少一个信 息确定第一资源时发送第一指示。
其中，SMF可自己生成第二指示，也可以从其他设备(例如，TSCTSF或TSN AF)获取第二指示。
C2：SMF对第一业务流进行整流，将第一业务流的每两个相邻数据突发的传输间隔调整为固定的时间间隔(即第二时间间隔)。
其中，第二时间间隔可为第一时间间隔的取值范围中的一个值，例如，第一时间间隔的取值范围的上限，第一时间间隔的取值范围的下限，第一时间间隔的取值范围的平均值，或第一时间间隔的取值范围的参考时长等。
可选的，当第一业务流的传输方向为下行方向时，SMF可指示UPF按照第二时间间隔传输第一业务流的数据突发。当第一业务流的传输方向为上行方向时，SMF可指示终端设备或输入输出(input output，IO)设备按照第二时间间隔传输第一业务流的数据突发。这样，第一业务流的数据突发到达空口(例如，UE的出口或AN设备的入口)时，可变为周期固定的业务流。
C3：SMF向AN设备发送用于指示第二时间间隔的信息；相应的，AN设备接收来自SMF的用于指示第二时间间隔的信息。
其中，用于指示第二时间间隔的信息可承载在现有的消息(例如，会话修改流程中的消息)中，也可以承载在新的消息中。
C4：AN设备根据第二时间间隔，确定用于传输第一业务流的数据突发的第二资源。
可选的，第二资源包括多个第三传输资源，每两个相邻第三传输资源之间的间隔为第二时间间隔。
可选的，在步骤C2中，也可以由TSCTSF或TSN AF来对第一业务流进行整流，即将第一业务流的每两个相邻数据突发的传输间隔调整为固定的时间间隔(即第二时间间隔)。此时，在步骤C2之前，SMF可将第一指示发送至TSCTSF或TSN AF；在步骤C3中，TSCTSF或TSN AF可通过SMF向AN设备发送用于指示第二时间间隔的信息。
通过该方法，当AN设备未成功根据至少一个信息确定第一资源时，SMF、TSCTSF或TSN AF可对第一业务流进行整流，将第一业务流调整为在空口中按照固定周期传输的业务流；然后AN设备可根据固定周期确定资源，从而可实现不固定周期业务流的传输。
可选的，第二信息为上述一个或多个信息中的任一信息，第一资源包括根据第二信息调度的至少一个第二传输资源；上述方法还包括：
D1：AN设备确定通过至少一个第二传输资源发送第一业务流的数据突发的时间偏移值。
其中，时间偏移值可表示第二通信设备能够根据至少一个第二传输资源发送第一业务流的数据突发的时刻与准备发送第一业务流的数据突发的时刻之间的差值。当第一业务流的传输方向为上行方向时，第二通信设备可为终端设备；当第一业务流的传输方向为下行方向时，第二通信设备可为AN设备。准备发送第一业务流的数据突发的时刻可为第二通信设备生成第一业务流的数据突发或接收到第一业务流的数据突发的时刻；其中，接收到第一业务流的数据突发的时刻可为：接收到第一业务流的第一个数据突发的时刻，或接收到第一业务流的最后一个数据突发的时刻，或接收到第一业务流的一个数据突发(例如，第一个数据突发或最后一个数据突发)的第一个数据包的时刻，或接收到第一业务流的一 个数据突发(例如，第一个数据突发或最后一个数据突发)的最后一个数据包的时刻。AN设备可自己测量接收到第一业务流的数据突发的时刻，也可以通过来自AF的参数(例如，突发达到时间(butst arrival time，BAT))确定接收到第一业务流的数据突发的时刻。第二通信设备能够根据至少一个第二传输资源发送第一业务流的数据突发的时刻可为：在准备发送第一业务流的数据突发的时刻之后，且距离准备发送第一业务流的数据突发的时刻最近的第二传输资源对应的时刻或时间窗。这样，时间偏移值可为一个值，也可以为一个时间窗。
例如，第二通信设备接收到第一业务流的数据突发的时刻为5ms，第一资源包括：3ms-4ms处的上行资源、(3+T*p)ms-(4+T*p)ms处的上行资源；当T＝3时，第二通信设备能够发送第一业务流的数据突发的时刻为6ms，时间偏移值为6-5＝1ms。
又例如，第二通信设备接收到第一业务流的数据突发的时刻为5ms，第一资源包括：3ms-4ms处的上行资源、(3+T*p)ms-(4+T*p)ms处的上行资源；当T＝3时，第二通信设备能够发送第一业务流的数据突发的时刻为6ms-7ms，时间偏移值为1ms-2ms。
可选的，本申请对步骤D1和AN设备确定第一资源之间的顺序不作限定。AN设备可在确定第一资源之后执行步骤D1；AN设备也可在确定第一资源之前执行步骤D1。
D2：AN设备向SMF发送用于指示时间偏移值的信息。
其中，用于指示时间偏移值的信息可以携带在现有的消息(例如，会话修改流程中的消息，示例性的，会话修改流程中的N2消息和PDU会话更新会话管理上下文(PDU session update SM context))中，也可以携带在新的消息中。
D3：SMF可将用于指示时间偏移值的信息发送至TSCTSF或TSN AF，当时间偏移值大于或等于第一阈值时，TSCTSF或TSN AF可重新生成至少一个信息，即重新执行S203。
其中，SMF可通过现有的消息(例如，会话修改流程中的消息)向TSCTSF或TSN AF发送用于指示时间偏移值的信息，也可通过新的消息向TSCTSF或TSN AF发送用于指示时间偏移值的信息。
第一阈值可以是预先设定的，也可以是TSCTSF或TSN AF从其他设备(例如，AF)获取的。
通过该方法，当通过AN设备调度的资源来传输第一业务流的数据突发时，若时间偏移值较大，导致第一业务流的数据突发的传输时延较大，则可重新生成至少一个信息，以便AN设备据此重新确定用于传输第一业务流的数据突发的资源，从而有可能减小该时间偏移值，进而可能减小第一业务流的数据突发的传输时延。
可选的，在S205之后，上述方法还包括：
E1：AN设备向AF发送用于指示期望传输第一业务流的数据突发的时间的信息。相应的，AF接收用于指示期望传输第一业务流的数据突发的时间的信息。
其中，期望传输第一业务流的数据突发的时间可包括以下至少一项：
1、期望传输第一业务流的数据突发的至少一个时间范围：该至少一个时间范围可以为第一资源对应的时间范围。例如，第一资源包括：3ms-4ms处的上行资源、(3+T*p)ms-(4+T*p)ms处的上行资源，该至少一个时间范围可包括：3ms-4ms、(3+T*p)ms-(4+T*p)ms。
2、期望传输第一业务流的数据突发的至少一个时刻：该至少一个时刻可以为第一资 源对应的时间范围内的时刻。例如，第一资源包括：3ms-4ms处的上行资源、(3+T*p)ms-(4+T*p)ms处的上行资源，该至少一个时刻可包括：3ms、(3+T*p)ms。
可选的，期望传输第一业务流的数据突发的时间可以为绝对时间，也可以为相对于参考时刻的相对时间，本申请对此不作限定。
此外，AN设备可依次通过控制面网元(例如，第一通信设备)向AF发送用于指示期望传输第一业务流的数据突发的时间的信息，也可通过用户面网元向AF发送用于指示期望传输第一业务流的数据突发的时间的信息。控制面网元和/或用户面网元可直接转发用于指示期望传输第一业务流的数据突发的时间的信息；也可以对用于指示期望传输第一业务流的数据突发的时间的信息进行处理之后，在转发处理后的信息，例如，当移动通信系统和AF不属于同一个时间系统时，控制面网元(例如，SMF)或用户面网元可将用于指示期望传输第一业务流的数据突发的时间的信息从移动通信系统的时间转换成AF的时间后，向AF发送转换后的时间。
用于指示期望传输第一业务流的数据突发的时间的信息可携带在现有的消息(例如，PDU会话过程中的消息)中，也可以携带在新的消息中，本申请对此不作限定。
E2：AF根据期望传输第一业务流的数据突发的时间，发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发。其中，第三通信设备可为IO设备。
当第一业务流的传输方向为下行方向时，AF可根据AF与AN设备之间的传输时延，以及根据期望传输第一业务流的数据突发的时间发送第一业务流的数据突发。例如，AF与AN设备之间的传输时延为2ms，期望传输第一业务流的数据突发的时间包括：4ms-6ms、(4+T*p)ms-(6+T*p)ms，AF可在2ms-4ms之间发送第一业务流的数据突发；这样，第一业务流的数据突发可在4ms-6ms到达AN设备，从而可在期望传输第一业务流的数据突发的时间内传输第一业务流的数据突发，减小第一业务流的数据突发的传输时延。
当第一业务流的传输方向为上行方向时，AF可根据AF与第三通信设备之间的传输时延，第三通信设备与终端设备之间的传输时延，以及期望传输第一业务流的数据突发的时间，指示第三通信设备发送第一业务流的数据突发。例如，当AF与第三通信设备之间的传输时延为3ms，第三通信设备与终端设备之间的传输时延为1ms，期望传输第一业务流的数据突发的时间包括：3ms-4ms、(3+T*p)ms-(4+T*p)ms，AF可在2ms-3ms之间指示第三通信设备发送第一业务流的数据突发；这样，当T＝3时，第一业务流的数据突发可在6ms-7ms之间到达终端设备，从而可在期望传输第一业务流的数据突发的时间内传输第一业务流的数据突发，减小第一业务流的数据突发的传输时延。
可选的，步骤E2还包括：
AF根据期望传输第一业务流的数据突发的时间，以及第一业务流中每两个相邻数据突发之间的传输间隔，发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发，使得第一业务流的每个数据突发到达空口的时刻都属于期望传输第一业务流的数据突发的时间。
例如，第一业务流的传输方向为下行方向，AF与AN设备之间的传输时延为2ms，期望传输第一业务流的数据突发的时间包括：4ms-6ms、(4+T*p)ms-(6+T*p)ms，第一业务流的相邻数据突发之间的时间间隔依次为：2ms，4ms，2ms，4ms，2ms，4ms；当T＝3时，AF可在4ms、6ms、10ms、12ms、16ms等时刻发送第一业务流的数据突发，这样，第一业务流的数据突发可在6ms、8ms、12ms、14ms、18ms到达AN设备，从而可在期望传输 第一业务流的数据突发的时间内传输第一业务流的数据突发，减小第一业务流的数据突发的传输时延。
又例如，第一业务流的传输方向为上行方向，AF与第三通信设备之间的传输时延为3ms，第三通信设备与终端设备之间的传输时延为1ms，期望传输第一业务流的数据突发的时间包括：3ms-4ms、(3+T*p)ms-(4+T*p)ms；当T＝3时，AF可在0ms、2.5ms、6ms、8.5ms、12ms指示第三通信设备发送第一业务流的数据突发；这样，第一业务流的数据突发可在4ms、6.5ms、10ms、12.5ms、16ms到达终端设备，从而可在期望传输第一业务流的数据突发的时间内传输第一业务流的数据突发，减小第一业务流的数据突发的传输时延。
通过图2所示的方法，对于不固定周期的业务流，第一通信设备可根据不固定周期的取值范围和AN设备的能力信息，生成至少一个信息，该至少一个信息中的任一信息可指示属于该取值范围内的时间范围，该时间范围对应的时长小于或等于该能力信息指示的AN设备调度资源的最大时长；这样，AN设备可根据该至少一个信息中的时间范围，为不固定周期的业务流确定资源，从而提高资源调度的效率。

AN设备向TSCTSF发送用于AN设备的能力信息，该能力信息用于指示AN设备调度资源的最大时长。AF向TSCTSF发送第一业务流的特征信息，该特征信息可包括用于指示第一时间间隔(即第一业务流的传输周期)的取值范围的信息。TSCTSF根据第一时间间隔的取值范围和AN设备的能力信息，生成至少一个TSCAC，任一TSCAC包含属于该取值范围的时间范围；该时间范围对应的时长小于或等于AN设备调度资源的最大时长。然后，TSCTSF向SMF发送至少一个TSCAC。SMF在生成与至少一个TSCAC一一对应的至少一个TSCAI之后，向AN设备发送至少一个TSCAI。任一TSCAI包含属于该取值范围的时间范围。AN设备根据接收到的至少一个TSCAI确定用于传输第一业务流的数据突发的资源。
通过该方法，对于不固定周期的业务流，TSCTSF可根据不固定周期的取值范围和AN设备的能力信息，生成至少一个TSCAC，任一TSCAC可指示属于该取值范围内的时间范围，该时间范围对应的时长小于或等于最大时长；这样，AN设备可根据该至少一个TSCAC对应的TSCAI为不固定周期的业务流确定资源，从而提高资源调度的效率。

通过该方法，AF可根据期望传输第一业务流的数据突发的时间，发送第一业务流的数据突发，或者，指示第三通信设备发送第一业务流的数据突发，使得第一业务流的每个数据突发到达空口的时刻都属于期望传输第一业务流的数据突发的时间，从而减小第一业务流的数据突发的传输时延。
本申请实施例提供了一种通信方法，该方法可应用于图1A-图1C所示的通信系统中。该方法示出了图2或图3所示方法的一种可能的实现方式。下面参阅图5所示的流程图，以会话管理网元为SMF，应用功能网元为AF，第一通信设备为TSCTSF为例，对该方法的流程进行具体说明。
S501：AN设备向TSCTSF发送AN设备的能力信息，该能力信息用于指示AN设备调度资源的最大时长。
其中，AN设备可通过SMF向TSCTSF发送该能力信息，具体内容可参考S201，此处不再赘述。
S502：AF向TSCTSF发送第一业务流的特征信息。
其中，该特征信息可包括以下至少一项：用于指示第一时间间隔的取值范围的信息、用于指示第一业务流的传输方向的信息、用于指示AF具有调节第一业务流的数据突发的发送时刻的能力的信息(即AF适配能力指示)。
其中，第一时间间隔为第一业务流的每两个相邻数据突发之间的传输间隔，第一时间间隔的取值范围的具体内容可参考S202，此处不再赘述。
可选的，AF可通过NEF向TSCTSF发送该特征信息。例如，AF可向NEF发送带有QoS的AF会话消息(AF-SESSION with QoS)，NEF向TSCTSF发送QoS和TSC辅助创建消息(Ntsctsf_QoSandTSCAssistance_Create)，AF-SESSION with QoS和Ntsctsf_QoSandTSCAssistance_Create中均包含该特征信息。
S503：TSCTSF根据第一时间间隔的取值范围和AN设备的能力信息，生成至少一个TSCAC。生成的方式可参考S203，重复之处不再赘述。
其中，任一TSCAC可包含以下至少一项：属于取值范围内的时间范围、第一反馈指示和用于指示第一业务流的传输方向的信息。其中，第一反馈指示用于指示AN设备反馈是否成功根据与至少一个TSCAC一一对应的至少一个TSCAI确定第一资源，即用于指示AN设备反馈辅助调度的结果。
例如(下面称为示例1)，第一时间间隔的取值范围为3ms-5ms，第一业务流的传输方向为上行方向，AN设备调度的连续上行资源的最大时长为1ms。TSCTSF生成TSCAC1和TSCAC2，TSCAC1包含时间范围1：3ms-4ms，TSCAC2包含时间范围2：4ms-5ms。
又例如，第一时间间隔的取值范围为3ms-5ms，第一业务流的传输方向为下行方向，AN设备调度的连续下行资源的最大时长为2ms；TSCTSF生成TSCAC3，TSCAC3包含时间范围3：3ms-5ms。
此外，TSCTSF还可根据周期步长将第一时间间隔的取值范围划分成一个或多个时间范围，每个时间范围包含在一个TSCAC中。示例性的，TSCTSF可在确定小于或等于最大时长的周期步长后，将第一时间间隔的取值范围划分成一个或多个时间范围，每个时间范围所对应的时长小于或等于该周期步长。其中，该最大时长为能力信息指示的AN设备 调度资源的最大时长。例如，第一时间间隔的取值范围为3ms-5ms，第一业务流的传输方向为上行方向，AN设备调度的连续上行资源的最大时长为1ms。TSCTSF在确定周期补偿为0.5ms后，可生成TSCAC4-TSCAC7；其中，TSCAC4包含时间范围4：3ms-3.5ms，TSCAC5包含时间范围5：3.5ms-4ms，TSCAC6包含时间范围6：4ms-4.5ms，TSCAC7包含时间范围7：4.5ms-5ms。
S504：TSCTSF向SMF发送至少一个TSCAC。
其中，TSCTSF可通过PCF向SMF发送至少一个TSCAC。例如，TSCTSF向PCF发送PCF策略授权更新请求(Npcf_PolicyAuthorization Update request)，Npcf_PolicyAuthorization Update request中包含至少一个TSCAC；PCF将每个TSCAC包含在对应的PCC规则中，得到至少一个PCC规则，其中，至少一个PCC规则和至少一个TSCAC一一对应；然后，PCF向SMF发送SM策略控制更新通知(Npcf_SMPolicyControl Update request)，Npcf_SMPolicyControl Update request中包含至少一个PCC规则。
S505：SMF推导出至少一个TSCAI后，向AN设备发送至少一个TSCAI。
其中，SMF可通过如下方式推导出至少一个TSCAI：SMF将包含TSCAC的每个PCC规则绑定到对应的QoS流；这样，至少一个PCC规则与至少一个QoS流一一对应绑定，也就是说，至少一个TSCAC与至少一个QoS流一一对应。然后，SMF可根据至少一个TSCAC，推导与至少一个QoS流一一对应的至少一个TSCAI。
其中，任一TSCAI可包含以下至少一项：属于取值范围内的时间范围、第一反馈指示和用于指示第一业务流的传输方向的信息。
例如，在示例1的基础上，至少一个TSCAI包括TSCAI1和TSCAI2，TSCAI1包含：3ms-4ms的时间范围1，TSCAI2包含：4ms-5ms的时间范围2。
另外，SMF可通过AMF向AN设备发送至少一个TSCAI。例如，SMF可通过AMF向AN设备发送PDU会话修改请求(PUD session modification request)，PUD session modification request中包含至少一个TSCAI。
S506：AN设备根据至少一个TACAI中的每个TACAI，确定用于传输第一业务流的数据突发的第一资源。具体内容可参考S205，此处不再赘述。
S507：AN设备向SMF发送第二反馈指示，该第二反馈指示可用于指示AN设备是否成功根据至少一个TSCAI确定第一资源。
其中，AN设备可通过AMF向SMF发送第二反馈指示。例如，AN设备向AMF发送N2消息，AMF向SMF发送PDU session update SM context；其中，N2消息和PDU session update SM context中包含第二反馈指示。
S508：若第二反馈指示用于指示AN设备未成功根据至少一个TSCAI确定第一资源，SMF可对第一业务流进行整流，即将第一业务流的每两个相邻数据突发的传输间隔调整为固定的时间间隔(即第二时间间隔)。
S508的具体内容可参考步骤C2，此处不再赘述。
S509：SMF向AN设备发送更新的TSCAI。其中，更新的TSCAI包含第二时间间隔。
其中，SMF向AN设备发送更新的TSCAI的方式可参考S505，此处不再赘述。
S507-S509为可选步骤。例如，当任一TSCAC和任一TSCAI中包括第一反馈指示时，可执行S507-S509；当至少一个TSCAC和至少一个TSCAI均不包含第一反馈指示时，可不执行S507-S509。
可选的，在S508中，SMF可替换为TSCTSF。此时，在S508之前，SMF可向TSCTSF发送第二反馈指示，例如，SMF向PCF发送SM策略控制更新请求(Npcf_SMPolicyControl Update request)，PCF向TSCTSF发送PCF策略授权更新通知(Npcf PolicyAuthorization Update notify)；Npcf_SMPolicyControl Update request和Npcf PolicyAuthorization Update notify中包含第二反馈指示。在S508后，TSCTSF可向SMF发送更新的TSCAC(包含第二时间间隔)后，SMF生成与更新的TSCAC对应的更新的TSCAI(包含第二时间间隔)。
可选的，若在S506中，AN设备成功确定用于传输第一业务流的数据突发的第一资源，该方法还可包括：S510-S513，和/或S514-S516。
S510：AN设备确定根据第一资源发送第一业务流的数据突发的时间偏移值。确定的方式可参考步骤D1，此处不再赘述。
S511：AN设备向SMF发送用于指示时间偏移值的信息。
其中，S511的具体内容可参考步骤D2，重复之处不再赘述。
另外，AN设备向SMF发送用于指示时间偏移值的信息的方式可参考S507中发送第二反馈指示的方式，此处不再赘述。
此外，本申请对S511和S507的执行顺序不作限定；第二反馈指示和用于指示时间偏移值的信息可以携带在相同的消息中，也可以携带在不同的消息中。
S512：当时间偏移值大于或等于第一阈值时，SMF可重新生成至少一个TSCAI。其中，任一TSCAI可对应于一个QoS流。
例如，TSCAI1包含时间范围1：3ms-4ms，TSCAI2包含时间范围2：4ms-5ms。当根据TSCAI1调度的资源对应的时间偏移值大于或等于第一阈值时，SMF可重新生成TSCAI3、TSCAI4和TSCAI2；其中，TSCAI3包含时间范围3：3ms-3.5ms，TSCAI4包含时间范围4：3.5ms-4ms，TSCAI2包含时间范围2：4ms-5ms。
S513：SMF向AN设备发送重新生成的至少一个TSCAI。然后，AN设备可执行步骤S506。
可选的，在S512中，SMF可以替换为TSCTSF，TSCAI可替换为TSCAC。此时，在S512之前，SMF可向TSCTSF发送用于指示时间偏移值的信息，例如，SMF向PCF发送Npcf_SMPolicyControl Update request，PCF向TSCTSF发送Npcf PolicyAuthorization Update notify；Npcf_SMPolicyControl Update request和Npcf PolicyAuthorization Update notify中包含用于指示时间偏移值的信息。在S512之后，TSCTSF向SMF发送重新生成的至少一个TSCAC；SMF重新生成与重新生成的至少一个TSCAC一一对应的至少一个TSCAI。
S514：AN设备确定根据第一资源发送第一业务流的数据突发的时间偏移值或期望传输第一业务流的数据突发的时间(下面可简称为期望时间)。
其中，AN设备确定时间偏移值的方式可参考步骤D1；期望时间的具体内容可参考步骤E1，此处不再赘述。
S515：AN设备向AF发送第一时间信息。
其中，第一时间信息包含用于指示时间偏移值的信息或用于指示期望时间的信息。
其中，AN设备可向TSCTSF发送第一时间信息；然后，TSCTSF向AF发送第一时间信息。例如，AN设备通过与发送第二反馈指示相同的方式，向TSCTSF发送第一时间信息；然后，TSCTSF可直接向AF发送第一时间信息，也可通过NEF向AF发送第一时间信息。
可选的，当第一时间信息包含用于指示时间偏移值的信息时，AN设备还可向AF发送包指示信息。其中，包指示信息可用于指示时间偏移值针对的数据突发中的数据包，即用于指示通过数据突发中的哪个数据包来计算时间偏移值。包指示信息和用于指示时间偏移值的信息可携带在相同的消息中，也可以携带在不同的消息中。
S516：AF根据第一时间信息，发送第一业务流的数据突发。
其中，AF根据期望时间发送第一业务流的数据突发的具体内容可参考步骤E2，重复之处不再赘述。可选的，AF可从包指示信息所指示的数据突发开始，根据期望时间发送第一业务流的数据突发。
AF可根据时间偏移值调整第一业务流的数据突发的发送时刻，以便减小时间偏移值。例如，当时间偏移值大于第二阈值时，AF可将第一业务流的数据突发的发送时刻延后k个时间单元，其中k个时间单元小于时间偏移值，k为正整数。又例如，当时间偏移值小于第三阈值时，AF可不对第一业务流的数据突发的发送时刻进行调整。
可选的，AF还可根据时间偏移值和包指示信息调整第一业务流的数据突发的发送时刻。例如，当包指示信息指示通过数据突发中的第一个数据包来计算时间偏移值时，AF可根据时间偏移值调整第一业务流的数据突发的第一个数据包的发送时刻。又例如，当包指示信息指示通过数据突发中的最后一个数据包来计算时间偏移值时，AF可根据时间偏移值调整第一业务流的数据突发的最后一个数据包的发送时刻。
通过该方法，TSCTSF可根据AN设备的调度能力，确定是否要对不固定周期传输的业务流的特征信息进行调整；当不固定周期的取值范围超出AN设备的调度能力时，即不固定周期的取值范围对应的时长大于AN设备调度资源的最大时长时，TSCTSF可将该取值范围拆分为多个时间范围；这样，在进行授权调度和半静态调度时，AN设备可根据每个时间范围为不固定周期传输的业务流确定资源，从而可提高AN设备调度资源的效率，降低空口时延，提高网络传输效率。
另外，通过该方法，当AF指示该AF具有调节第一业务流的数据突发的发送时刻的能力，但不固定周期的取值范围超出AN设备的调度能力时，由TSCTSF等第一通信设备将该取值范围拆分为多个时间范围，并据此重新确定用于AN设备辅助调度的至少一个信息(例如，至少一个TSCAC)。这样，不需要AF调整第一业务流的数据突发的发送时刻，也可降低第一业务流的数据突发的空口时延，提高网络传输效率。
本申请实施例提供了另一种通信方法，该方法可应用于图1A-图1C所示的通信系统中。下面参阅图6所示的流程图，以会话管理网元为SMF，应用功能网元为AF，第一通信设备为TSCTSF为例，对该方法的流程进行具体说明。
S601：AF向TSCTSF发送第一业务流的特征信息。
S601的具体内容可参考S502，此处不再赘述。
S602：TSCTSF在确定TSCAC之后，向SMF发送TSCAC。
其中，该TSCAC可包含以下至少一项：特征信息中的第一时间间隔的取值范围、第一反馈指示和用于指示第一业务流的传输方向的信息。其中，第一时间间隔的取值范围的具体内容可参考S202；第一反馈指示用于指示AN设备反馈是否成功根据与TSCAC对应的TSCAI确定第一资源，即用于指示AN设备反馈辅助调度的结果。
另外，TSCTSF向SMF发送TSCAC的方式可参考S504，此处不再赘述。
S603：SMF推导出TSCAI后，通过PDU会话修改流程中的消息向AN设备发送TSCAI。
其中，该TSCAI可包含以下至少一项：第一时间间隔的取值范围、第一反馈指示和用于指示第一业务流的传输方向的信息。
另外，SMF推导出TSCAI的方式可参考S505，此处不再赘述。
S604：AN设备根据该TSCAI，确定用于传输第一业务流的数据突发的第一资源。
其中，S604的具体内容可参考S205，重复之处不再赘述。
可选的，AN设备还可根据TSCAI和第一业务流的数据突发的到达时间，确定用于传输第一业务流的数据突发的第一资源。例如，TSCAI中的周期参数包含：周期为Tms，偏移范围±1ms；第一业务流的第一数据突发的到达时间为t±1ms，即最早为t-1ms，最晚为t+1ms，则AN设备确定的第一资源可包括：[(t-1)～(t+1)]ms处的资源、[(t-1)+T*p～(t+1)+T*p]ms处的资源。其中，T为正数，p为正整数，t为正数。
其中，AN设备可通过如下方式之一获取第一业务流的数据突发的到达时间。
方式1：AN设备可从AF获取该第一业务流的数据突发的到达时间。例如，AF可通过S601-S603中的消息或信息向AN设备发送该第一业务流的数据突发的到达时间。
方式2：AN设备可从用于发送第一业务流的数据突发的第二通信设备获取第一业务流的数据突发的到达时间。第二通信设备的具体内容可参考步骤D1，此处不再赘述。
S605：AN设备向SMF发送第二反馈指示，该第二反馈指示可用于指示AN设备是否成功根据TSCAI确定第一资源。
S606：若第二反馈指示用于指示AN设备未成功根据TSCAI确定第一资源，SMF可对第一业务流进行整流，即将第一业务流的每两个相邻数据突发的传输间隔调整为固定的时间间隔(即第二时间间隔)。
S607：SMF向AN设备发送更新的TSCAI。其中，更新的TSCAI包含第二时间间隔。
S605-S607的具体内容可参考S507-S509，此处不再赘述。
可选的，在S606中，SMF可替换为TSCTSF。此时，在S606之前，SMF可向TSCTSF发送第二反馈指示，例如，SMF向PCF发送SM策略控制更新请求(Npcf_SMPolicyControl Update request)，PCF向TSCTSF发送PCF策略授权更新通知(Npcf PolicyAuthorization Update notify)，Npcf_SMPolicyControl Update request和Npcf PolicyAuthorization Update notify中包含第二反馈指示。在S606后，TSCTSF向SMF发送更新的TSCAC(包含第二时间间隔)后，SMF生成与更新的TSCAC对应的更新的TSCAI。
可选的，若在S604中，AN设备成功确定用于传输第一业务流的数据突发的第一资源，该方法还可包括：S608-S611。
S608：AN设备确定根据第一资源发送第一业务流的数据突发的时间偏移值或期望传输第一业务流的数据突发的时间(下面可简称为期望时间)。
S609：AN设备向AF发送第一时间信息。
其中，第一时间信息包含用于指示时间偏移值的信息或用于指示期望时间的信息。
S610：AF根据第一时间信息，发送第一业务流的数据突发。
S608-S610的具体内容可参考S514-S516，此处不再赘述。
S611：AF在更新第一业务流的特征信息之后，可向TSCTSF发送更新的特征信息，即重新执行S602及后续步骤，以便AN设备进行辅助调度。
通过该方法，AF可提供包含不固定周期的业务流的特征信息，AN设备根据不固定周 期进行调度(例如，进行下行半静态调度或上行免授权调度)，为第一业务流确定与不固定周期对应的时间窗内的资源，从而可减小不固定周期业务流的数据突发的传输时延。
并且，AN设备可将时间偏移值或期望时间反馈给AF，以便AF据此调整业务流的数据突发的发送时刻，从而降低不固定周期业务流的数据突发的传输时延。
此外，当AN设备无法根据不固定周期进行调度时，AN设备可向控制面网元(例如，SMF或TSCTSF)发送第二反馈指示；然后，TSCTSF可对业务流进行整流，将其变为周期固定的业务流，并向AN设备提供包含固定周期的参数，以便AN设备进行辅助调度，从而可提高网络传输效率。
本申请实施例提供了又一种通信方法，该方法可应用于图1A-图1C所示的通信系统中。下面参阅图7所示的流程图，以会话管理网元为SMF，应用功能网元为AF，第一通信设备为TSCTSF为例，对该方法的流程进行具体说明。
S701：AF向TSCTSF发送第一业务流的特征信息。
其中，该特征信息可包括以下至少一项：用于指示第三时间间隔的取值范围的信息、第一业务流的第一数据突发的到达时间和用于指示第一业务流的传输方向的信息。
其中，第三时间间隔为第一业务流的第一数据突发和第二数据突发之间的传输间隔。第一数据突发和第二数据突发可以是相邻的数据突发，也可以不是相邻的数据突发。用于指示第三时间间隔的取值范围的信息可包括以下至少一项：
1、用于指示第三时间间隔的上限和下限的信息。例如，第三时间间隔的上限为5ms，第三时间间隔的下限为3ms，表示第三时间间隔的取值范围为3ms-5ms。
2、用于指示参考时长的信息，以及用于指示第三时间间隔的取值范围相对于参考时长的偏移的信息。其中，第三时间间隔的取值范围相对于参考时长的偏移可以为绝对值，也可以为相对值。例如，参考时长为4ms，第三时间间隔的取值范围相对于参考时长的偏移为±1ms，表示第三时间间隔的取值范围为3ms-5ms。又例如，参考时长为4ms，第三时间间隔的取值范围相对于参考时长的偏移为±25％，表示第三时间间隔的取值范围为3ms-5ms。
另外，第一业务流的第一数据突发的到达时间可以为第一数据突发的BAT，用于指示第一数据突发达到第二通信设备的时刻。当第一业务流的传输方向为上行方向时，第二通信设备可为UE；当第一业务流的传输方向为下行方向时，第二通信设备可为AN设备。用于指示第一业务流的传输方向可直接或间接指示第一业务流的传输方向为上行方向或下行方向。
可选的，AF向TSCTSF发送第一业务流的特征信息的方式可参考S502，此处不再赘述。
S702：TSCTSF在确定TSCAC之后，向SMF发送TSCAC。
其中，该TSCAC包含以下至少一项：特征信息中的第三时间间隔的取值范围、第一业务流的第一数据突发的到达时间、第一反馈指示和用于指示第一业务流的传输方向的信息。第一反馈指示的具体内容可参考S602，此处不再赘述。
另外，TSCTSF向SMF发送TSCAC的方式可参考S504，此处不再赘述。
S703：SMF推导出TSCAI后，通过PDU会话修改流程中的消息向AN设备发送TSCAI。
其中，该TSCAI包含以下至少一项：第三时间间隔的取值范围、第一业务流的第一数 据突发的到达时间、第一反馈指示和用于指示第一业务流的传输方向的信息。
另外，SMF推导出TSCAI的方式可参考S505，此处不再赘述。
S704：AN设备根据该TSCAI，确定用于传输第一业务流的第二数据突发的第一资源。
其中，AN设备可根据第三时间间隔的取值范围和第一业务流的第一数据突发的到达时间，确定第二数据突发到达第二通信设备可能的时间范围(即时间窗)，并为第二数据突发预留与该时间窗对应的资源。例如，第一业务流的第一数据突发的到达时间为T0ms，第三时间间隔的取值范围为3ms-5ms(假设周期为4ms，下限为3ms，上限为5ms)；此时，第一资源可包括(T0+3)ms-(T0+5)ms处的资源，其中，T0为正数。
可选的，在确定用于传输第二数据突发的第一资源时，AN设备还可考虑上下行配置。AN设备可根据第三时间间隔的取值范围和第一业务流的第一数据突发的到达时间，确定第二数据突发到达第二通信设备可能的时间范围(即时间窗)，并为第二数据突发预留该时间窗内与第一业务流的传输方向一致的资源。例如，第一业务流的第一数据突发的到达时间为3ms，第三时间间隔的取值范围为3ms-5ms，第一业务流的传输方向为下行方向，上下行配置信息指示：7ms-9ms处的资源为下行资源；此时，第一资源可包括7ms-9ms处的资源。
S705：AN设备向SMF发送第二反馈指示，该第二反馈指示可用于指示AN设备是否成功根据TSCAI确定第一资源。
S706：若第二反馈指示用于指示AN设备未成功根据TSCAI确定第一资源，SMF可对第一业务流进行整流，将第一数据突发和第二数据突发之间的传输间隔调整为固定的时间间隔(即第四时间间隔)。
其中，第四时间间隔可为第三时间间隔的取值范围中的一个值，例如，第三时间间隔的取值范围的上限，第三时间间隔的取值范围的下限，第三时间间隔的取值范围的平均值，或第三时间间隔的取值范围的参考时长等。
S707：SMF向AN设备发送更新的TSCAI。其中，更新的TSCAI包含第四时间间隔。
S705-S707的具体内容可参考S507-S509，此处不再赘述。
可选的，在S706中，SMF可替换为TSCTSF。此时，在S706之前，SMF可向TSCTSF发送第二反馈指示，例如，SMF向PCF发送SM策略控制更新请求(Npcf_SMPolicyControl Update request)，PCF向TSCTSF发送PCF策略授权更新通知(Npcf PolicyAuthorization Update notify)，Npcf_SMPolicyControl Update request和Npcf PolicyAuthorization Update notify中包含第二反馈指示。在S706后，TSCTSF向SMF发送更新的TSCAC(包含第四时间间隔)后，SMF可生成与该更新的TSCAC对应的更新的TSCAI。
通过该方法，AN设备可根据两个数据突发之间的传输间隔的取值范围，以及其中一个数据突发的到达时间，确定另一个数据突发的到达时间，从而可动态的为另一个数据突发确定与该数据突发的到达时间匹配的资源，进而降低该数据突发在空口的传输时间。
