技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法、通信装置及通信系统。
背景技术
目前，新无线(new radio，NR)系统采用共享信道传输，时频资源在终端之间是动态共享的，基站通过调度特性实现上下行链路的时频资源的分配，除了能保证系统吞吐率和用户资源公平外，还可以提升系统容量和网络性能。调度特性包括如下基本功能：优先级计算、调制编码方案(Modulation and Coding Scheme，MCS)选择、资源分配等。
传统的上行调度，终端周期性地发送用于请求时频资源的调度请求(Scheduling Request，SR)，根据协议，发送调度请求的周期可能比较大，比如最大可高达80毫秒(ms)。因此，在最坏的情况下，终端如果有上行数据发送，需要等待较长时间才能发送调度请求，导致增加上行时延。
如何降低终端请求获得上行调度的时频资源的时延，目前还没有很好的方法。

本申请实施例中的接入网设备可以是无线接入网设备，为便于说明，在本申请的实施例中，以基站作为接入网设备的一个举例进行描述。
传统工业场景下的通信技术，通常通过有线进行连接。在有线连接的工业现场网中，有以下两种类型的通信消息定义于现有的工业通信协议中：
1)非周期消息：业务服务器与工业终端等之间进行的、用于组态(configure)、维护等用途的非实时消息，通常为L3消息；其中，工业终端包括工业控制器(如可编程逻辑控制器(Programmable Logic Controller，PLC))、工业设备(如输入/输出(Input/Output Device，I/O)设备)等；
2)周期消息：PLC与PLC、或PLC与I/O设备之间发送的与生产业务强相关的实时消息或准实时消息，通常为L2消息；其中，周期消息通常采用“周期性”的总线传递机制。
随着5G工业互联网技术的不断发展，目前工业现场网中的工业终端的通信正在从基于有线的通信向基于无线的通信方式转换。其中，工业终端本身不在3GPP定义的范围内，也即工业终端不能直接与3GPP网络进行通信。目前，工业终端一般是通过客户端设备(Customer Premise Equipment，CPE)接入到3GPP网络，这里的CPE可以是图2(a)或图2(b)中所示的UE，即3GPP网络中的终端。
图3为工业现场网中的工业终端接入5G网络示意图。5G局域网(local area network，LAN)为大量的工业终端提供数据接入，并提供具有严格的质量保证的传输服务，如时延、可靠性等要符合工业标准。以工业终端包括PLC和I/O设备为例，通常，一个CPE下挂 一个PLC，但对于I/O设备则可能出现一个CPE下挂多个IO的情况。工业场景中，PLC和I/O设备间是通过固定的周期性消息进行实时业务通信，其通信关系在组态时就已经确定。由于业务和功能的不同，不同业务消息的周期可能并不一致，即使是挂于同一CPE下的两个I/O设备，也有可能执行具有不同通信周期的业务。示例性地，图3中的设备之间的通信周期如表1所示。
表1
通信双方 通信周期(单位：毫秒)
PLC 1与PLC 2 1
PLC 2与I/O设备1 2
PLC 2与I/O设备2 4
PLC 2与I/O设备3 8
需要说明的是，工业终端可以不具备3GPP通信能力，工业终端可以通过3GPP网络中的终端，使用3GPP网络进行通信。或者，为未来通信中，当工业终端具备3GPP通信能力时，则该工业终端可以看做是3GPP网络中的终端，如可以是图2(a)或图2(b)中的UE。
为了降低上行时延，本申请实施例引入上行预调度功能，具体的，不论终端是否向基站发送调度请求，基站都会每隔一段时间，通过预调度参数集主动调度一次终端，为终端分配合适的时频资源，用于终端发送和接收数据，该方式可以减少终端获得上行调度的时频资源的时延。
本申请实施例中，每个预调度参数集中包含以下三种参数：
1)预调度最小间隔周期(MinPreallocationPeriod)：可以用X表示，指的是主动进行预调度的最小时间间隔。
2)预调度最大用户数量(PreschUeNumUpperLimit)：可以用Y表示，指的是一个时间单元中最多可以预调度的用户数量，其中，时间单元可以是符号、时隙、帧或秒等；
3)调度数据总量(PreallocationSize)：可以用Z表示，指的是预调度用户的可被调度的数据总量。
图4为本申请实施例提供的一种通信方法示意图，该方法包括以下步骤：
步骤401，AF确定第一预调度参数集和第一预调度参数集中的每个预调度参数集对应的5QI，该第一预调度参数集包括多个设备群组分别对应的预调度参数集。
这里的AF比如可以是工业现场使能服务(Industrial Field Enable Service，IFES)设备。在具体实现中，IFES可以部署于UPF，或者是与UPF共同部署于移动边缘计算(Mobile Edge Compute，MEC)设备上。
作为一种实现方法，这里的设备群组指的是由3GPP网络中的终端构成的群组，因此一个设备群组中包含一个或多个3GPP网络中的终端。
作为另一种实现方法，这里的设备群组指的是由工业终端构成的群组，因此一个设备群组中包含一个或多个工业终端，这里的工业终端不具备3GPP网络通信能力，但可以通过3GPP网络的终端使用3GPP网络进行通信。
以设备群组中包含工业终端为例，结合图3的示例。在5G LAN组建完成后，CPE(如 3GPP网络的终端)上线，创建以太类型或IP类型的PDU会话。然后业务服务器对工业终端(如PLC、I/O设备)进行组态，得到现场网的拓扑信息，以及还设置工业终端中的业务消息的周期。其中，现场网的拓扑信息用于表示多个工业终端与CPE之间的连接关系。AF可以从业务服务器中获取到现场网组态信息，其中，现场网组态信息包含现场网的拓扑信息和工业终端中的业务消息的周期。这里的工业终端比如可以是图3中的PLC 1、PLC 2、I/O设备1、I/O设备2或I/O设备3。AF获取到组态信息后，可以将多个工业终端划分为多个设备群组，其中，每个设备群组中包含一个或多个工业终端，然后AF为每个设备群组确定一个预调度参数集。确定的一个或多个预调度参数集构成第一预调度参数集。其中，一个预调度参数集对应一个周期，不同的预调度参数集对应不同的周期。
具体的，AF可以根据现场网中的工业终端的业务消息的周期，对现场网中的工业终端进行分组，得到多个设备群组。其中，同一个设备群组内的工业终端的业务消息的周期相同，不同设备群组内的工业终端的业务消息的周期不同。需要说明的是，如果一个工业终端中包含周期不同的多个业务消息，则该工业终端可以被划分到多个设备群组中。
示例性地，现场网中有8个工业终端，分别为工业终端1至工业终端8。按照工业终端中的业务消息的周期，将该8个工业终端分组如下：
设备群组1：{工业终端1、工业终端2、工业终端3}；
设备群组2：{工业终端1、工业终端4、工业终端5、工业终端6}；
设备群组3：{工业终端2、工业终端7、工业终端8}；
其中，设备群组1对应的业务消息的周期为1ms，也即设备群组1的工业终端中都有周期为1ms的业务消息；设备群组2对应的业务的周期为2ms，也即设备群组2的工业终端中都有周期为2ms的业务消息；设备群组3对应的业务的周期为4ms，也即设备群组3的工业终端中都有周期为4ms的业务消息。需要说明的是，工业终端1中既包含周期为1ms的业务消息，也包含周期为2ms的业务消息，因此工业终端1既属于设备群组1，也属于设备群组2。同样的，工业终端2中既包含周期为1ms的业务消息，也包含周期为4ms的业务消息，因此工业终端1既属于设备群组1，也属于设备群组3。
在得到多个设备群组之后，可以根据每个设备群组确定一个预调度参数集。以多个设备群组中的任意一个设备群组为例(以下称为第一设备群组)，AF可以根据第一设备群组对应的业务消息的周期，确定第一设备群组对应的预调度参数集中的预调度最小间隔周期，根据第一设备群组内的设备数量，确定第一设备群组对应的预调度参数集中的预调度最大用户数量，以及根据第一设备群组的数据总量，确定第一设备群组对应的预调度参数集中的调度数据总量。
以上述示例为例，设备群组1、设备群组2、设备群组3分别对应预调度参数集1、预调度参数集2、预调度参数集3，如下所示：
预调度参数集1：X＝1ms，Y＝3，Z＝100；
预调度参数集2：X＝2ms，Y＝4，Z＝200；
预调度参数集3：X＝4ms，Y＝3，Z＝400。
具体的，由于设备群组1中的工业终端均包含周期为1ms的业务消息，因此设备群组1对应的预调度参数集1中的预调度最小间隔周期X取值为1ms。由于设备群组1中包含3个工业终端，因此设备群组1对应的预调度参数集1中的预调度最大用户数量Y取值为3。由于设备群组1的3个工业终端的数据总量为100，因此设备群组1对应的预调度参数 集1中的调度数据总量Z取值为100。同样的，可以得到预调度参数集2和预调度参数集3。该预调度参数集1、预调度参数集2和预调度参数集3可以统称为第一预调度参数集。
进一步的，AF还可以为每个设备群组分配一个5QI。比如，AF可以根据第一设备群组的QoS需求信息确定第一设备群组对应的5QI，其中，第一设备群组是多个设备群组中的任意一个设备群组。其中，一个5QI是一组QoS参数的索引，因此，一个5QI指示了一组QoS参数。其中，一组QoS参数比如包括资源类型(Resource Type)、优先等级(Priority Level)、分组数据包时延预算(Packet Delay Budget，PDB)、分组包错误率(Packet Error Rate，PER)、默认最大数据突发量(Default Maximum Data Burst Volume，Default MDBV)、默认平均窗(Default Averaging Window)中的一个或多个。
多个设备群组中的每个设备群组对应一个预调度参数集，每个设备群组对应一个5QI，因此每个预调度参数集对应一个5QI。
以上述示例为例，比如分配的5QI如下所示：
设备群组1，对应预调度参数集1，对应5QI 1；
设备群组2，对应预调度参数集2，对应5QI 2；
设备群组3，对应预调度参数集3，对应5QI 3。
步骤402，AF向基站发送第一预调度参数集和第一预调度参数集中的每个预调度参数集对应的5QI。相应地，基站接收第一预调度参数集和第一预调度参数集中的每个预调度参数集对应的5QI。
以上述示例为例，AF向基站发送的第一预调度参数集和第一预调度参数集中的每个预调度参数集对应的5QI包括以下信息：
预调度参数集1，以及预调度参数集1对应的5QI 1；
预调度参数集2，以及预调度参数集2对应的5QI 2；
预调度参数集3，以及预调度参数集2对应的5QI 3。
作为一种实现方法，AF可以通过5G核心网，向基站发送第一预调度参数集，以及第一预调度参数集中的每个预调度参数集对应的5QI。比如，AF经由NEF、PCF以及SMF等网元，向基站发送第一预调度参数集，以及第一预调度参数集中的每个预调度参数集对应的5QI。
作为另一种实现方法，AF也可以通过基站对应的网管设备，向基站发送第一预调度参数集，以及第一预调度参数集中的每个预调度参数集对应的5QI。比如，AF通过基站的操作、管理和维护(operation，administration and management，OAM)系统开放的应用编程接口(Application programming interface，API)，向基站发送第一预调度参数集，以及第一预调度参数集中的每个预调度参数集对应的5QI。
步骤403，基站接收来自终端的目标业务的数据包，该数据包中包含QFI。
这里的终端指的是3GPP网络中的终端。目标业务的数据包中的QFI是由该终端添加到数据包的包头的。
如果上述设备群组是由非3GPP网络中的终端(如工业终端)构成，则该设备群组内的工业终端是通过该3GPP网络中的终端(也称为CPE)进行目标业务的数据包的收发。这里的目标业务指的是工业终端中的业务。
如果上述设备群组是由3GPP网络中的终端构成，则该设备群组内的终端可以直接通过3GPP网络进行目标业务的数据包的收发。这里的目标业务指的是3GPP网络的终端中 的业务。
步骤404，基站确定数据包中的QFI对应的第一5QI。
其中，基站上存储有QFI与5QI的对应关系。比如，在上述步骤401之后，AF可以向PCF发送策略授权请求，其中携带目标业务的业务流描述信息和QoS需求，该业务流描述信息可以包括IP五元组、虚拟局域网(virtual local area network，VLAN)标识等。然后PCF根据业务流描述信息生成包过滤器，该包过滤器可以是以太类型的包过滤器或IP类型的包过滤器。以及，PCF根据QoS需求，为该目标业务分配5QI。然后，PCF向SMF发送策略计费控制(Policy and Charging Control，PCC)规则，该PCC规则中包含包过滤器和QoS属性，该QoS属性中包含5QI。SMF收到PCC规则后，为该PCC规则分配QFI，以及生成QoS配置(QoS profile)、QoS规则(QoS rule)和包检测规则(Packet Detection Rule，PDR)。其中，QoS配置中包含PCC规则中的QoS属性，QoS规则中包含QFI和PCC规则中的包过滤器，PDR中包含QFI和PCC规则中的包过滤器。然后，SMF向基站发送QFI和QoS配置，向终端发送QoS规则，以及向UPF发送包检测规则。基站根据收到的QFI和QoS配置，可以确定QFI与5QI的对应关系，比如确定QFI 1对应5QI 1，QFI 2对应5QI 2，QFI 3对应5QI 3。
该步骤404中，基站确定目标业务的数据包中的QFI对应的是第一5QI。该第一5QI比如可以是5QI 1，5QI 2或5QI 3，等等。示例性地，比如基站确定目标业务的数据包中的QFI是QFI 1，则基站根据QFI 1与5QI 1的对应关系，确定QFI 1对应的5QI 1，该5QI 1即为第一5QI。
步骤405，基站从第二预调度参数集中确定第一5QI对应的预调度参数集。
其中，第二预调度参数集包括第一预调度参数集。
作为一种实现方法，第二预调度参数集与第一预调度参数集相同。也即基站是从第一预调度参数集中确定第一5QI对应的预调度参数集。以上述示例为例，假设第一5QI是5QI 1，则确定第一预调度参数集中与5QI 1对应的预调度参数集是预调度参数集1。假设第一5QI是5QI 2，则确定第一预调度参数集中与5QI 2对应的预调度参数集是预调度参数集2。
作为另一种实现方法，第二预调度参数集包括第一预调度参数集，以及还包括默认的预调度参数集。其中，默认的预调度参数集是预配置在基站上的，或者是通过协议预定义的。因此基站是从第一预调度参数集和默认的预调度参数集中的确定第一5QI对应的预调度参数集。作为示例，基站上预配置有默认的预调度参数集a，默认的预调度参数集b，默认的预调度参数集c，其中，默认的预调度参数集a，默认的预调度参数集b，默认的预调度参数集c分别对应5QI a，5QI b，5QI c。如果上述第一5QI是5QI 1，则基站确定的预调度参数集是预调度参数集1，如果上述第一5QI是5QI b，则基站确定的预调度参数集是默认的预调度参数集b。
作为另一种实现方法，第二预调度参数集包括第一预调度参数集，以及还包括第四预调度参数集。其中，第四预调度参数集是基站根据以下方法得到的：基站接收来自AF的第三预调度参数集，该第三预调度参数集中包括一个或多个预调度参数集；基站根据第三预调度参数集，更新基站上的默认的预调度参数集，得到第四预调度参数集。也即基站可以根据从AF收到的第三预调度参数集对本地的默认的预调度参数集进行更新，从而得到更新后的预调度参数集，即第四预调度参数集。后续，基站可以从第一预调度参数集和第四预调度参数集中，确定第一5QI对应的预调度参数集。其中，该第三预调度参数集可以 与上述第一预调度参数集相同或不同。AF生成第三预调度参数集的方法与生成第一预调度参数集的方法类似，不再赘述。以基站上的任意一个默认的预调度参数集为例，该默认的预调度参数集中包含第一预调度最大用户数量和第一调度数据总量；第三预调度参数集中的任意一个预调度参数集中包含第二预调度最大用户数量和第二调度数据总量，该默认的预调度参数集与该任意一个预调度参数集包含相同的预调度最小间隔周期，则基站可以根据第二预调度最大用户数量和第二调度数据总量，更新默认的预调度参数集中的第一预调度最大用户数量和第一调度数据总量，得到第四预调度参数集中的一个预调度参数集。下面结合具体示例说明。比如，基站上预配置有默认的预调度参数集a(X＝6ms，Y＝4，Z＝300)，对应5QI a，基站从AF收到第三预调度参数集，第三预调度参数集中包含预调度参数集4(X＝6ms，Y＝5，Z＝400)，则基站可以将默认的预调度参数集更新为默认的预调度参数集a'(X＝6ms，Y＝5，Z＝400)，该默认的预调度参数集a'对应5QI a。需要说明的是，作为另一种实现方法，如果AF还向基站发送预调度参数集4对应的5QI 4，则更新后的预调度参数集a'也可以由对应5QI a更新为对应5QI 4。
作为另一种实现方法，第二预调度参数集包括第一预调度参数集，以及还包括第五预调度参数集。其中，第五预调度参数集是基站从AF获取到的，AF生成第五预调度参数集的方法是：AF获取默认的预调度参数集，AF根据上述第一调度参数集，更新默认的预调度参数集，得到第五预调度参数。比如，AF获取的默认的预调度参数集中包含第一预调度最大用户数量和第一调度数据总量，第一预调度参数集中的任意一个预调度参数集中包含第三预调度最大用户数量和第三调度数据总量，该默认的预调度参数集与该任意一个预调度参数集包含相同的预调度最小间隔周期，则AF根据第三预调度最大用户数量和第三调度数据总量，更新默认的预调度参数集中的第一预调度最大用户数量和第一调度数据总量，得到第五预调度参数集中的一个预调度参数集。下面结合具体示例说明。比如，AF获取默认的预调度参数集a(X＝6ms，Y＝4，Z＝300)，对应5QI a，基站确定的第一预调度参数集中包含预调度参数集5(X＝6ms，Y＝8，Z＝600)，然后根据默认的预调度参数集a得到更新的默认的预调度参数集a”(X＝6ms，Y＝8，Z＝600)，该更新的默认的预调度参数集a”是第五预调度参数集中的一个预调度参数集。需要说明的是，AF在向基站发送第五预调度参数集的同时，还可以向基站发送第五预调度参数集中的每个预调度参数集对应的5QI。
步骤406，基站根据第一5QI对应的预调度参数集，对终端的上行资源进行预调度。
根据上述方案，由于为基站配置多个预调度参数集，则基站可以根据预调度参数集对终端的上行资源进行预调度，从而减少终端获得上行资源的时间，进而可以提升终端的通信效率。并且，由于是由AF为基站配置一个或多个预调度参数集，可以实现根据实际需要动态配置或调整预调度参数集，有利于准确为终端分配相应的资源。
需要说明的是，上述AF为基站配置的预调度参数集以及预调度参数集对应的5QI是可以动态调整的。比如，AF获取到现场网的组态信息发生变化，例如是增加或减少工业终端，则AF可以更新预调度参数集以及预调度参数集对应的5QI。再比如，AF获知现场网中的工业终端中新增或删除业务，或者是现场网中的工业终端的已有业务的周期发生变化，则AF也可以更新预调度参数集以及预调度参数集对应的5QI。下面结合前述的示例，来说明更新过程。
比如，更新前，AF确定的设备群组、预调度参数集以及5QI如下所示：
设备群组1：{工业终端1、工业终端2、工业终端3}；
设备群组2：{工业终端1、工业终端4、工业终端5、工业终端6}；
设备群组3：{工业终端2、工业终端7、工业终端8}；

预调度参数集2：X＝2ms，Y＝4，Z＝200；
预调度参数集3：X＝4ms，Y＝3，Z＝400。

新增工业终端9，且工业终端9中的业务消息的周期为4ms，则更新后的设备群组如下所示：
设备群组1：{工业终端1、工业终端2、工业终端3}；
设备群组2：{工业终端1、工业终端4、工业终端5、工业终端6}；
设备群组3：{工业终端2、工业终端7、工业终端8、工业终端9}；

预调度参数集3：X＝4ms，Y＝4，Z＝500。
以及，根据每个设备群组的QoS需求信息，分别为每个设备群组重新分配一个5QI。需要说明的是，如果某个设备群组没有发生变化，则也可以继续使用之前的5QI。

其中，设备群组1、设备群组2、设备群组3分别对应预调度参数1、预调度参数2、预调度参数3，如下所示：

预调度参数集2：X＝2ms，Y＝3，Z＝150；
预调度参数集3：X＝4ms，Y＝3，Z＝400。
以及，根据每个设备群组的QoS需求信息，分别为每个设备群组重新分配一个5QI。需要说明的是，如果某个设备群组没有发生变化，则也可以继续使用之前的5QI。

设备群组3：{工业终端2、工业终端7、工业终端8}；
其中，设备群组1、设备群组2、设备群组3分别对应预调度参数1、预调度参数2、预调度参数3，如下所示：
预调度参数集1：X＝1ms，Y＝2，Z＝50；
预调度参数集2：X＝2ms，Y＝5，Z＝250；
预调度参数集3：X＝4ms，Y＝3，Z＝400。
以及，根据每个设备群组的需求信息，分别为每个设备群组重新分配一个5QI。需要说明的是，如果某个设备群组没有发生变化，则也可以继续使用之前的5QI。

以及，根据每个设备群组的QoS需求信息，分别为每个设备群组重新分配一个5QI。需要说明的是，如果某个设备群组没有发生变化，则也可以继续使用之前的5QI。
后续，AF可以向基站配置更新后的预调度参数以及相应的5QI。
下面结合一个工业现场网的具体示例，对上述图4的实施例进行说明。图5为本申请实施例提供的一种通信方法，该方法包括以下步骤：
步骤501，AF获取现场网的组态信息。
AF比如可以是IFES设备。现场网组态信息包含现场网的拓扑信息和工业终端中的业务消息的周期，具体参考图4的实施例的描述。
步骤502，AF根据现场网的组态信息，对工业终端进行分组。
步骤503，AF为每个设备群组确定一个预调度参数集。
步骤504，AF为每个设备群组确定一个5QI。
步骤505，AF向基站发送第一预调度参数集和第一预调度参数集中的每个预调度参数集对应的5QI。相应地，基站接收第一预调度参数集和第一预调度参数集中的每个预调度参数集对应的5QI。
上述步骤501至步骤505的具体实现，可以参考上述步骤401至步骤402的描述。
步骤506，AF向PCF发送策略授权请求。相应地，PCF接收策略授权请求。
步骤507，PCF向SMF发送PCC规则。相应地，SMF接收PCC规则。
步骤508，SMF向基站发送QoS配置和QFI。相应地，基站接收QoS配置和QFI。
步骤509，SMF向UPF发送PDR。相应地，UPF接收PDR。
步骤510，SMF向终端发送QoS规则。相应地，终端接收QoS规则。
上述步骤506至步骤510的具体实现，可以参考上述步骤404中的描述。
在对UPF、基站以及终端做上述配置之后，针对工业终端的目标业务的上行数据流，后续工业终端向终端发送该上行数据流的上行数据包，终端根据QoS规则中的包过滤器对目标业务的上行数据包进行匹配，若匹配上了，则该上行数据包的包头添加QFI，然后将上行数据包发送给基站。基站在收到上行数据包后，可以根据上行数据包中的QFI，确定与该QFI对应的5QI，根据该5QI对该上行数据流的上行数据包执行QoS保障，以及基站还确定该5QI对应的预调度参数集，并根据该预调度参数集执行相应的上行预调度。
针对工业终端的目标业务的下行数据流，UPF收到该下行业务流的下行数据包后，根据PDR中的包过滤器对目标业务的下行数据包进行匹配，若匹配上了，则该下行数据包的包头添加QFI，然后将下行数据包发送给基站。基站在收到下行数据包后，可以根据下行数据包中的QFI，确定与该QFI对应的5QI，根据该5QI对该下行数据流的下行数据包执行QoS保障。
