为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，第五代(5th generation，5G)移动通信系统应运而生，5G移动通信系统也可以称为新空口(new radio，NR)系统。例如5G移动通信系统中定义了三大类应用场景：增强型移动宽带(enhanced mobile broadband，eMBB)场景、高可靠低时延通信(ultrareliable and low latencycommunications，URLLC)场景以及海量机器类通信(massive machine type communications，mMTC)场景。
上述不同类型的应用场景下，终端设备对移动通信系统的需求也不同，在eMBB场景和URLLC场景下的终端设备可以称为“传统(legacy)终端设备”，在mMTC场景下的终端设备可以是降低能力(reduced capbility，REDCAP)终端设备，由于REDCAP终端设备的自身能力受限，REDCAP终端设备进行节能优化，以降低REDCAP终端设备的功耗。
在目前的NR系统中，终端设备具有如下三种状态：空闲态(idle state)、非激活态(inactive state)、和连接态(connected state)。当终端设备处于非激活态或空闲态时，终端设备会周期性的接收网络设备发送的寻呼消息。具体的，当处于非激活态或空闲态的终端设备有下行业务产生的时候，网络设备通过发送寻呼消息告知终端设备有下行业务。网络设备会在多个寻呼周期发送寻呼消息，其中每个寻呼周期会出现一个寻呼机会(paging occasion，PO)。网络设备可以在PO内发送寻呼消息，相应地，终端设备在PO处检测(detect)是否有寻呼消息。这一过程中，终端设备监听用于调度寻呼消息的下行控制信息(downlink control information，DCI)，终端设备在接收到DCI后，根据DCI接收寻呼消息，如果终端设备在寻呼消息中检测到自己的标识，则会发起随机接入流程，以转入连接态。如果终端设备在寻呼消息中没有检测到自己的标识，确定该终端设备没有被寻呼。
然而，上述寻呼方案存在功耗浪费的问题。
发明内容
本申请实施例提供了一种通信方法和通信装置，提供一种降低终端设备的功耗的可能。
第一方面，本申请实施例提供一种通信方法。该方法可以由终端设备执行，也可以由终端设备中的芯片执行。此处以第一终端设备执行为例进行描述。第一终端设备在第一寻呼机会PO接收下行控制信息，所述下行控制信息用于指示至少一个终端设备组是否接收所述下行控制信息调度的寻呼消息，和/或所述下行控制信息用于指示至少一个终端设备组是否监听所述第一PO之后的N个第二PO，其中，所述N为正整数；第一终端设备根据所述 下行控制信息确定是否接收所述寻呼消息，和/或根据所述下行控制信息确定是否监听所述N个第二PO。
相应的，第二方面，本申请实施例还提供一种可以由网络设备执行或者由网络设备中的芯片执行的通信方法。此处以网络设备执行为例进行描述。
网络设备确定至少一个终端设备组是否接收下行控制信息调度的寻呼消息,和/或，确定至少一个终端设备组是否监听第一寻呼机会PO之后的N个第二PO，所述N为正整数；网络设备在所述第一PO发送所述下行控制信息，所述下行控制信息用于指示至少一个终端设备组是否接收所述寻呼消息；和/或所述下行控制信息用于指示至少一个终端设备组是否监听所述N个第二PO。
可以理解的，上述方法中的A和/或B可以有三种方案：
第一种方案中，仅执行A，上述方案均执行“和/或”前面的方案；
第二种方案中，仅执行B，上述方案均执行“和/或”后面的方案；
第三种方案中，执行A和B，上述方案中与A和B对应的方案均被执行。
上述方案中，由于下行控制信息可以指示至少一个终端设备组是否接收下行控制信息调度的寻呼消息，即对于同一个终端设备组，可以都接收寻呼消息，或者都不接收寻呼消息，因此对于一个终端设备而言，如果该终端设备能够根据接收到的针对该终端设备组的下行控制信息就可以确定该终端设备是否接收寻呼消息，对于没有被寻呼的终端设备，就可以不接收寻呼消息，因此，上述方案可以节约终端设备接收寻呼消息所用的功耗。因此，上述方案能够提供一种降低终端设备的功耗的可能。例如，上述方案能够降低下行控制信息所指示的不接收该下行控制信息指示的不接收寻呼消息的终端设备的功耗。
上述方案中，由于下行控制信息可以指示至少一个终端设备组是否监听N个第二PO，即对于同一个终端设备组，可以都监听N个PO，或者都不监听N个PO，因此对于一个终端设备而言，确定该终端设备对应的终端设备组，结合接收到的针对该终端设备组的下行控制信息就可以确定该终端设备是否监听N个PO，当终端设备确定不监听N个PO时，上述方案可以节约终端设备监听N个PO的功耗。从而上述方案能够提供一种降低终端设备的功耗的可能。例如，上述方案能够降低下行控制信息所指示的不监听N个第二PO的终端设备的功耗。

在本申请的上述方案中，当下行控制信息中有K个第一比特时，每个第一比特用于指示K个终端设备组中的一个终端设备组是否接收下行控制信息调度的寻呼消息，因此第一终端设备解析下行控制信息中的K个第一比特中与第一终端设备组对应的第一比特，就可以确定该第一终端设备是否接收寻呼消息。例如，第一终端设备组对应于K个第一比特中的第1个第一比特，则第一终端设备解析下行控制信息中的第1个第一比特，就可以确定该第一终端设备是否接收寻呼消息。

在一种可能的实现方式中，所述K个终端设备组中的每个终端设备组对应的第一比特在所述K个第一比特中的位置是预先配置的。在本申请的上述方案中，预先配置每个终端设备组对应的第一比特在K个第一比特中的位置，因此通过解析K个第一比特中的一个第一比特的取值，就可以根据该第一比特与终端设备组的对应关系确定出该终端设备组是否需要接收寻呼消息。

具体实施方式
下面结合附图，对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
本申请实施例的技术方案可以应用于各种数据处理的通信系统，例如码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它系统等。术语“系统”可以和“网络”相互替换。CDMA系统可以实现例如通用无线陆地接入(universal terrestrial radio access，UTRA)，CDMA2000等无线技术。UTRA可以包括宽带CDMA(wideband CDMA，WCDMA)技术和其它CDMA变形的技术。CDMA2000可以覆盖过渡标准(interim standard，IS)2000(IS-2000)，IS-95和IS-856标准。TDMA系统可以实现例如全球移动通信系统(global system for mobile communications，GSM)等无线技术。OFDMA系统可以实现诸如演进通用无线陆地接入(evolved UTRA，E-UTRA)、超级移动宽带(ultra mobile broadband，UMB)、IEEE 802.11(Wi-Fi)，IEEE 802.16(WiMAX)，IEEE 802.20，Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在长期演进(long term evolution，LTE)和基于LTE 演进的各种版本是使用E-UTRA的UMTS的新版本。第五代(5thgeneration，5G)通信系统、新空口(new radio，NR)是正在研究当中的下一代通信系统。此外，所述通信系统还可以适用于面向未来的通信技术，都适用本申请实施例提供的技术方案。本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
图1示出了本申请实施例的一种可能的无线接入网(radio access network，RAN)的结构示意图。所述RAN可以为2G网络的无线接入网络(即所述RAN包括基站和基站控制器)，或可以为3G网络的无线接入系统(即所述RAN包括节点B(NodeB，NB)和无线网络控制器(radio network controller，RNC))，或可以为4G网络的无线接入系统(即所述RAN包括演进节点B(evolved NodeB，eNB))，或可以为5G网络的无线接入系统。当然，本申请实施例的RAN还可以是上述系统中的无线接入系统。
所述RAN包括一个或多个网络设备。所述网络设备可以是任意一种具有无线收发功能的设备，或，设置于具体无线收发功能的设备内的芯片。所述网络设备包括但不限于：接入网设备，例如基站(base station，BS)，节点B、eNB、第五代通信系统中的基站gNodeB或gNB、未来通信系统中的基站或接入网设备、WiFi系统中的接入节点、无线中继节点、或无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，或中继站等。基站可以支持上述提及的一种或者多种技术的网络，或者未来演进网络。基站可以包含一个或多个共站或非共站的传输接收点(transmission receiving point，TRP)。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)或者分布单元(distributed unit，DU)等。网络设备还可以是服务器，提供接入功能的可穿戴设备或车载设备等。以下以网络设备为基站为例进行说明。
图1中的多个网络设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端设备1-6进行通信，也可以通过中继站与终端设备1-6进行通信。终端设备1-6可以支持与不同技术的多个基站进行通信。例如，终端设备可以支持与支持LTE网络的基站通信，也可以支持与支持5G网络的基站通信，还可以支持与LTE网络的基站以及5G网络的基站的双连接。
网络设备又可以称为RAN节点。一些RAN节点的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved NodeB，eNB)、无线网络控制器(radio network controller，RNC)、节点B(NodeB，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home evolved NodeB，或home NodeB，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。在一种网络结构中，RAN节点可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点。
终端设备1-6，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、或终端等，是一种向用户提供语音和/或数据连 通性的设备，或，设置于该设备内的芯片。例如，终端设备可以为具有无线连接功能的手持式设备、或车载设备等。又如，终端设备可以为手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。本申请实施例提供的终端设备还可以是低复杂度终端设备和/或处于覆盖增强A模式下的终端设备。
如图1所示，本申请实施例的通信系统包括基站和UE1～UE6。在该通信系统中，基站发送系统信息、RAR消息和寻呼消息中的一种或多种给UE1～UE6中的一个或多个UE。
在本申请实施例的通信系统还可以是包括UE4～UE6，而不包括UE1～UE3和基站，在该通信系统中，UE5可以实现基站的功能，UE5可以发送系统信息、控制信息和寻呼消息中的一种或多种给UE4和UE6中的一个或多个UE。
上述寻呼方案中，一个PO对应的终端设备都接收寻呼消息，检测寻呼消息是否携带终端设备的标识，并根据终端设备的标识的检测结果才能确定是否被寻呼。因此，上述方案中，终端设备无法在检测寻呼消息中的终端设备标识之前确定是否被寻呼。可见，无论终端设备在该PO内是否被寻呼，均检测寻呼消息，而对于那些没有被寻呼的终端设备而言，该检测存在功耗浪费的问题。尤其是对应有续航能力要求较高的终端设备，比如REDCAP用于可穿戴终端设备时需要维持数天的续航时间，采用上述寻呼方案时会造成功耗浪费的问题更为明显。
需要说明的是，本申请实施例并不仅限于应用到REDCAP的终端设备，而是对于REDCAP的终端设备效果更为显著，而普通的终端设备同样可以采用本申请实施例提供的方案，同样在一定程度上提供了减少终端设备的功耗浪费的可能。
本申请实施例提供一种下行控制信息，该下行控制信息用于指示至少一个终端设备组是否接收寻呼消息，或者，该下行控制信息用于指示至少一个终端设备组是否监听所述第一PO之后的N个第二PO，或者，该下行控制信息用于指示至少一个终端设备组是否接收寻呼消息以及指示该至少一个终端设备组是否监听所述第一PO之后的N个第二PO。其中，N为正整数。
进一步的，本实施例的下行控制信息中包括至少一个字段组,该至少一个字段组指示至少一个终端设备组是否接收寻呼消息，或者，该至少一个字段组指示至少一个终端设备组是否监听第一PO之后的N个第二PO，或者，该至少一个字段组指示至少一个终端设备组是否接收寻呼消息以及指示该至少一个终端设备组是否监听所述第一PO之后的N个第二PO。
例如，至少一个终端设备组为K个终端设备组，本申请实施例的下行控制信息中包括K个字段组，K个字段组与K个终端设备组一一对应。K为正整数，即K可以为等于1或大于1的整数。因此，与终端设备组对应的字段组用于指示该终端设备组是否接收寻呼消息，和/或与终端设备组对应的字段组用于指示是否监听所述第一PO之后的N个第二PO。
可选的，一种实施例中，该下行控制信息用于指示至少一个终端设备组是否接收寻呼消息。该实施例中的下行控制信息可以包括：K个第一比特，至少一个终端设备组为K个终端设备组，K为正整数，K个第一比特与K个终端设备组一一对应，K个第一比特中的每个第一比特用于指示K个终端设备组中的一个终端设备组是否接收下行控制信息调度的寻呼消息。
可以理解的，上述K个字段组中每个字段组包括K个第一比特中的一个。
第一比特可以是下行控制信息中的其中一个比特或多个比特。本实施例不限定第一比特在下行控制信息中的位置。
可选的，K个终端设备组中的每个终端设备组对应的第一比特在K个第一比特中的位置是预先设置的。其中，本实施例中的预先设置可以是预先定义的，或者可以是网络设备为终端设备预先配置的。
例如，每个终端设备组对应的第一比特中在K个第一比特中的位置可以是在终端设备和网络设备预先定义的。
又如，每个终端设备组对应的第一比特中在K个第一比特中的位置可以是网络设备通过信令通知给终端设备的。具体地，该信令可以是系统消息，或无线资源控制(radio resource control,RRC)信令，或媒体接入控制(media access control,MAC)控制元素(control element，CE)或下行控制信息(downlink control information，DCI)。
这样，当下行控制信息中有K个第一比特时，每个第一比特用于指示K个终端设备组中的一个终端设备组是否接收下行控制信息调度的寻呼消息，因此第一终端设备解析下行控制信息中的K个第一比特中与第一终端设备组对应的第一比特，就可以确定该第一终端设备是否接收寻呼消息。例如，第一终端设备组对应于K个第一比特中的第1个第一比特，则第一终端设备解析下行控制信息中的第1个第一比特，就可以确定该第一终端设备是否接收寻呼消息。又例如，对于三个终端设备组，例如分别为第一终端设备组，第二终端设备组，第三终端设备组，三个终端设备组分别对应的第一比特在K个第一比特中的位置是预先定义的，比如第一终端设备组对应于K个第一比特中的第1个第一比特，第二终端设备组对应于K个第一比特中的第2个第一比特，第三终端设备组对应于K个第一比特中的第3个第一比特。由于第一终端设备组对应于K个第一比特中的第1个第一比特，因此第一终端设备解析下行控制信息中的第1个第一比特，就可以确定属于第一终端设备组的第一终端设备是否接收寻呼消息。
可选的，又一种实施例中，该下行控制信息用于指示至少一个终端设备组是否监听所述第一PO之后的N个第二PO。该实施例中的下行控制信息可以包括：K个第二比特，至少一个终端设备组为K个终端设备组，所述K为正整数，K个第二比特与K个终端设备组一一对应，K个第二比特中的每个第二比特用于指示K个终端设备组中的一个终端设备组是否监听所述第一PO之后的N个第二PO。
可以理解的，上述K个字段组中每个字段组包括K个第二比特中的一个。
第二比特可以是下行控制信息中的其中一个比特或多个比特。本实施例不限定第二比特在下行控制信息中的位置。
可选的，K个终端设备组中的每个终端设备组对应的第二比特在K个第二比特中的位 置是预先设置的。其中，本实施例中的预先设置可以是预先定义的，或者可以是网络设备为终端设备预先配置的。
例如，每个终端设备组对应的第二比特中在K个第二比特中的位置可以是在终端设备和网络设备预先定义的。
又如，每个终端设备组对应的第二比特中在K个第二比特中的位置可以是网络设备通过信令通知给终端设备的。具体地，该信令可以是系统消息，或RRC信令，或MACCE或DCI。
这样，下行控制信息中有K个第二比特时，每个第二比特用于指示K个终端设备组中的一个终端设备组是否监听N个第二PO，因此第一终端设备解析下行控制信息中的K个第二比特中与第一终端设备组对应的第二比特，就可以确定该第一终端设备是否监听N个第二PO。例如，第一终端设备组对应于K个第二比特中的第1个第二比特，则第一终端设备解析下行控制信息中的第1个第二比特，就可以确定该第一终端设备是否监听N个第二PO。又例如，对于三个终端设备组，记为第一终端设备组，第二终端设备组，第三终端设备组，三个终端设备组对应的第一比特在K个第一比特中的位置是预先定义的，比如第一终端设备组对应于K个第一比特中的第1个第一比特，第二终端设备组对应于K个第一比特中的第2个第一比特，第三终端设备组对应于K个第一比特中的第3个第一比特。由于第一终端设备组对应于K个第一比特中的第1个第一比特，因此第一终端设备解析下行控制信息中的第1个第一比特，就可以确定属于第一终端设备组的第一终端设备是否监听N个第二PO。
可选的，又一种实施例中，该下行控制信息用于指示至少一个终端设备组是否接收寻呼消息以及指示该至少一个终端设备组是否监听所述第一PO之后的N个第二PO。该实施例中的下行控制信息可以包括：K个第一比特和K个第二比特，K个第一比特和K个第二比特与K个终端设备组一一对应。K个第一比特和K个第二比特的实现方式可以参照上文的描述。
可以理解的，上述K个字段组中每个字段组包括K个第一比特中的一个以及K个第二比特中的一个。
本实施例中，K个第一比特可以位于K个第二比特之前；或者，K个第一比特可以位于K个第二比特之后；或者，K个终端设备组中的每个终端设备组对应的第一比特和第二比特是相邻的，即K个字段组中的第一比特和第二比特是相邻的，为一个字段组，多个终端设备组对应的字段组组成K个字段组。
需要说明的是，本实施例中的第一比特是为了说明用于指示终端设备组是否接收下行控制信息调度的寻呼消息的信息可以是通过比特的形式实现。而本发明实施例并不限定对于指示至少一个终端设备组中的一个终端设备组的第一比特包含的比特个数，例如，可以是每个终端设备组对应1个比特，也可以是每个终端设备组对应大于1的比特数，本实施例均将其称为第一比特，可以理解的是本实施例中的第一比特又可以理解为是第一比特组。类似的，第二比特也可以理解为是第二比特组，即第一比特和第二比特都可以由一个或多个比特来实现。
本实施例中，下行控制信息中指示是否接收寻呼消息，如果该下行控制消息指示一个终端设备组不接收寻呼消息，属于该终端设备组的终端设备在接收该下行控制信息后可以 不接收该下行控制信息调度的寻呼消息，甚至可以关闭终端设备的接收电路或降低接收电压进入睡眠状态，从而终端设备因不接收寻呼消息可以实现节省功耗的目的。例如下行控制信息中指示是否监听N个第二PO，如果该下行控制消息指示一个终端设备组不监听N个第二PO，属于该终端设备组的终端设备在接收该下行控制信息后可以不监听该N个第二PO，甚至可以关闭终端设备的接收电路或降低接收电压进入睡眠状态，从而终端设备因不监听该N个第二PO可以实现节省功耗的目的。类似地，下行控制信息中指示是否接收寻呼消息以及是否监听N个第二P0,如果该下行控制消息指示一个终端设备组不接收寻呼消息，和/或，指示该终端设备组不监听该N个第二P0，属于该终端设备组的终端设备在接收该下行控制信息后可以不接收该下行控制信息调度的寻呼消息，和/或，属于该终端设备组的终端设备在接收该下行控制信息后可以不监听该N个第二PO，甚至可以关闭终端设备的接收电路或降低接收电压进入睡眠状态，从而节省接收该寻呼消息，和/或，监听该N个第二PO的功耗。此外，下行控制消息中按照一个终端设备组的方式进行指示，相比于按照单个终端设备的方式可以降低信令开销，同时可以保证下行控制消息的接收性能。每个终端设备组对应的第一比特中在K个第一比特中的位置，和/或，每个终端设备组对应的第二比特中在K个第二比特中的位置预先定义或者由网络设备通过信令通知给终端设备，可以保证终端设备和网络设备按照相同的方式解析下行控制信息，避免因对下行控制信息的解析方式不一致导致的功耗增加或者无法及时接收寻呼消息的问题，其中预先定义的方式可以节省网络设备信令开销，由网络设备信令通知的方式实现更灵活，可以提高网络设备调度的灵活性。
进一步的，本实施例还提供了一种终端设备组的确定方法。
在本申请的一些实施例中，至少一个终端设备组是与非连续接收周期、寻呼概率、业务特征、或终端设备的标识中的一个或者多个关联的。
其中，至少一个终端设备组可以与上述参数中的一个相关联。例如，至少一个终端设备组与非连续接收周期相关联。或者，至少一个终端设备组与寻呼概率相关联。或者，至少一个终端设备组可以与上述参数中的任意两个相关联。例如，至少一个终端设备组与业务特征和终端设备的标识。或者，至少一个终端设备组可以与上述参数中任意三个相关联。例如，至少一个终端设备组与非连续接收周期、寻呼概率以及业务特征相关联。或者，至少一个终端设备组可以与上述四个参数都相关联。具体可以根据应用场景确定至少一个终端设备组与上述参数中的哪种参数有关，或者可以根据预定义的规则确定至少一个终端设备组。该预定义的规则与上述参数中的一个或者多个相关。
其中，非连续接收(discontinuous reception，DRX)周期是指终端设备的DRX周期，对于不同的终端设备可以配置不同的DRX周期。DRX周期可以是网络设备发送给终端设备的，例如网络设备向终端设备发送DRX周期指示信息，终端设备根据该DRX周期指示信息确定终端设备的DRX周期。例如，终端设备的DRX周期为RRC信令配置的DRX周期，和/或，NAS信令配置的DRX周期，以及系统消息广播的缺省(default)DRX周期中的最小值，其中NAS信令是由核心网设备发送给终端设备的，RRC信令是由网络设备发送给终端设备的，上述DRX周期指示信息可以由RRC信令承载。需要说明的是，对于DRX周期通过核心网设备发送给终端设备的情况，核心网设备也会向网络设备发送该终端设备的DRX周期， 因此对于这种情况，网络设备也可以获取终端设备的DRX周期。
寻呼概率指终端设备被寻呼的概率，寻呼概率可以是网络设备发送给终端设备的，网络设备可以为不同的终端设备配置不同的寻呼概率。寻呼概率也可以是核心网设备发送给终端设备的，核心网设备可以为不同的终端设备配置不同的寻呼概率。需要说明的是，对于寻呼概率通过核心网设备发送给终端设备的情况，核心网设备也会向网络设备发送该终端设备的寻呼概率，因此对于这种情况，网络设备也可以获取终端设备的寻呼概率。
业务特征是指终端设备的业务具有的特征，例如一种类型的终端设备可能存在上行业务流量大于下行业务流量的特征，另一种类型的终端设备可能存在下行业务流量大于上行业务流量的特征。
终端设备的标识具有多种实现方式，例如终端设备的标识可以是核心网设备为终端设备分配的临时标识，例如终端设备的标识可以是5G-S-临时移动订阅标识符(5G S-temporary mobile subscription identifier,5G-S-TMSI)。也可以是其他类型的终端设备的标识,此处仅作举例，不用于对本申请实施例的限定。需要说明的是，对于终端设备的标识通过核心网设备发送给终端设备的情况，核心网设备也会向网络设备发送该终端设备的标识，因此对于这种情况，网络设备也可以获取终端设备的标识。
接下来进一步介绍至少一个终端设备组与DRX周期、寻呼概率、业务特征、或终端设备的标识中的一个或者多个参数的关联关系。
一种实施方式中，至少一个终端设备组与DRX周期相关联，至少两个终端设备组分别对应不同的DRX周期。
进一步的，具有相同的非连续接收周期的终端设备可以属于同一个终端设备组，具有不同的非连续接收周期的终端设备可以属于不同的终端设备组。
例如，网络设备可以向第一终端设备发送第一非连续接收周期，第一终端设备接收第一非连续接收周期，网络设备和第一终端设备均能够根据第一非连续接收周期确定第一终端设备所属的第一终端设备组，其中，至少两个终端设备组分别对应不同的非连续接收周期。本申请实施例中，网络设备可以采用非连续接收周期作为终端设备的分组依据，此处只是一种可行的实现方式。
本实施例中，并不限定具有不同DRX周期的终端设备均在不同的终端设备组，可以是至少两个终端设备组对应不同的DRX周期。例如，当网络设备配置的DRX周期有三种，而终端设备组有两个，则可以将两个DRX周期对应到同一个终端设备组。例如，网络设备和终端设备可以根据DRX周期以及某一阈值确定具有第一DRX周期的终端设备属于第一终端设备组，网络设备和终端设备可以根据DRX周期以及某一阈值确定具有第二DRX周期的终端设备属于第一终端设备组，网络设备和终端设备可以根据DRX周期以及某一阈值确定具有第三DRX周期的终端设备属于第二终端设备组。
因此，在本申请的一些实施例的方法还可以包括：
网络设备向第一终端设备发送非连续接收周期指示信息，第一终端设备接收该非连续接收周期指示信息，其中，非连续接收周期指示信息用于确定第一非连续接收周期。该步骤可以是在发送下行控制信息之前执行。
网络设备根据非连续接收周期指示信息指示的第一非连续接收周期确定第一终端设备 所属的第一终端设备组，而且，第一终端设备也能够根据该非连续接收周期指示信息确定的第一非连续接收周期确定第一终端设备所属的第一终端设备组。
一种实施方式中，至少一个终端设备组与寻呼概率相关联。至少两个终端设备组分别对应不同的寻呼概率。或者，寻呼概率区间由寻呼概率门限划分，至少一个终端设备组与寻呼概率区间相关联，至少两个终端设备组分别对应不同的寻呼概率区间，或者，至少一个终端设备组与寻呼概率门限相关联，至少两个终端设备组分别对应不同的寻呼概率门限。例如，寻呼概率门限为寻呼区间的端点。一个示例中，寻呼概率门限为0.5，则第一寻呼概率区间为大于0、且小于0.5的区间，该第一寻呼概率区间关联第一终端设备组，第二寻呼概率区间为大于或等于0.5、且小于1的区间，该第二寻呼概率区间关联第二终端设备组。
进一步的，寻呼概率在相同的寻呼概率区间的终端设备可以属于同一个终端设备组，寻呼概率在不同的寻呼概率区间的终端设备可以属于不同的终端设备组。或者，具有相同寻呼概率的终端设备属于同一个终端设备组，具有不同的寻呼概率的终端设备可以属于不同的终端设备组。
例如，网络设备和第一终端设备能够根据第一寻呼概率门限确定寻呼概率区间，并根据该第一终端设备对应的第一寻呼概率和寻呼概率区间确定第一终端设备所属的第一终端设备组，其中，至少两个终端设备组分别对应不同的寻呼概率。可以理解的是，网络设备和第一终端设备还可以直接比较寻呼概率门限和第一寻呼概率确定第一终端设备所属的第一终端设备组，而不确定寻呼概率区间。本申请实施例中，网络设备可以采用寻呼概率区间作为终端设备的分组依据，此处只是一种可行的实现方式，不作为对本申请实施例的限定。
本实施例中，网络设备进一步可以向第一终端设备发送该第一寻呼概率。
可选的，网络设备可以向第一终端设备发送寻呼概率门限指示信息，寻呼概率门限指示信息用于指示寻呼概率门限，则第一终端设备接收寻呼概率门限指示信息，解析该寻呼概率门限指示信息确定网络设备指示的寻呼概率门限。该步骤可以是在发送下行控制信息之前执行。
例如，网络设备可以向第一终端设备发送一个或多个寻呼概率门限，第一终端设备接收该一个或多个寻呼概率门限，即，寻呼概率区间或寻呼概率门限可以是网络设备为终端设备配置的。或者，寻呼概率门限或寻呼概率门限也可以是预先设置在第一终端设备和网络设备中的，即，寻呼概率门限或寻呼概率门限可以是预定义的。
又如，网络设备可以向第一终端设备发送第一寻呼概率门限，第一终端设备接收该第一寻呼概率门限；网络设备和第一终端设备能够根据该第一终端设备对应的第一寻呼概率确定第一终端设备所属的第一终端设备组，其中，不同终端设备组对应不同的寻呼概率。本申请实施例中，网络设备可以采用寻呼概率作为终端设备的分组依据，此处只是一种可行的实现方式，不作为对本申请实施例的限定。类似的，本实施方式中并不限定具有不同寻呼概率的终端设备均在不同的终端设备组，可以是至少两个终端设备组对应不同的寻呼概率。例如，当网络设备配置的寻呼概率有三种，而终端设备组有两个，则可以将两个寻呼概率对应到同一个终端设备组。
又一种实施方式中，至少一个终端设备组与业务特征或终端设备类别相关联。至少两个终端设备组对应不同的业务特征。或者，至少两个终端设备组对应不同的终端设备类别。
网络设备和第一终端设备能够根据业务特征确定第一终端设备所属的第一终端设备组；或者，
网络设备和第一终端设备均能够根据终端设备类别与终端设备组之间的对应关系确定第一终端设备所属的第一终端设备组。
进一步的，具有相同的业务特征的终端设备为同一个终端设备组，具有不同的业务特征的终端设备为不同的终端设备组，网络设备根据业务特征确定第一终端设备所属的第一终端设备组，另外，第一终端设备根据业务特征确定第一终端设备所属的第一终端设备组，本申请实施例中，网络设备可以采用业务特征作为终端设备的分组依据，此处只是一种可行的实现方式，不作为对本申请实施例的限定。可选的，不同的业务特征可以是上行业务触发类型和下行业务触发类型。
进一步地，具有相同的终端设备类别的终端设备为同一个终端设备组，具有不同的终端设备类别的终端设备为不同的终端设备组，网络设备根据终端设备类别确定第一终端设备所属的第一终端设备组，其中，不同的终端设备类别可以对应不同的业务特征，例如类型1的终端设备可能存在上行业务流量大于下行业务流量的特征，类型2的终端设备可能存在下行业务流量大于上行业务流量的特征。或者不同的终端设备类别可以对应不同的终端类型，比如REDCAP终端设备，非REDCAP终端设备，另外，第一终端设备根据终端设备类别确定第一终端设备所属的第一终端设备组，
本申请实施例中，网络设备可以采用终端设备类别作为终端设备的分组依据，此处只是一种可行的实现方式，不作为对本申请实施例的限定。
在本申请的另一些实施例中，网络设备和第一终端设备根据终端设备类别与终端设备组之间的对应关系确定第一终端设备所属的第一终端设备组。具体的，可以预先设置终端设备类别与终端设备组之间的对应关系，从而可以根据终端设备所属的类别进行终端设备的分组。
又一种实施方式中，至少一个终端设备组与终端设备的标识关联。
网络设备和第一终端设备均能够根据第一终端设备的标识确定第一终端设备所属的第一终端设备组。
具体的，基于第一终端设备的标识，可以确定第一终端设备所属的第一终端设备组，例如第一终端设备的标识为ID1，则第一终端设备所属的第一终端设备组为终端设备组1，第一终端设备的标识为ID2，则第一终端设备所属的第一终端设备组为终端设备组2。
例如，终端设备的标识和终端设备组之间存在对应关系，根据该对应关系即可确定终端设备所属的终端设备组。一种示例中，该对应关系可以是一种运算关系。例如通过对终端设备的标识进行取模运算得到的值确定终端设备所属的终端设备组。当然，还可以是其他的运算关系，此处不做限定。另一种示例中，还可以是根据终端设备的标识中的某一位数确定终端设备所属的终端设备组。例如，第一终端设备的标识的最后一位是1，则确定该第一终端设备为终端设备组1，第一终端设备的标识的最后一位是3，则确定该第一终端设备为终端设备组3。
可选的，网络设备或第一终端设备可以根据第一终端设备的标识和终端设备组的个数之间的对应关系确定第一终端设备所属的第一终端设备组。
具体的，例如终端设备组的个数为M，第一终端设备的标识和终端设备组的个数之间的对应关系可以是网络设备为终端设备预先配置的或者是终端设备和网络设备中预先定义的。这样，可以根据第一终端设备的标识和终端设备组的个数之间的对应关系确定第一终端设备所属的第一终端设备组。
进一步的，在本申请的一些实施例中，第一终端设备的标识和终端设备组的个数满足如下关系：
(UE_ID)mod K＝m1，其中，UE_ID表示第一终端设备的标识，K为终端设备组的个数，mod表示取模运算，m1为UE_ID对K取模后的余数，m1对应于第一终端设备所属的第一终端设备组的编号；
或者，
floor(UE_ID/(N*Ns))mod K＝m2，其中，UE_ID表示第一终端设备的标识，K为终端设备组的个数，N为一个非连续接收周期中寻呼帧的个数，Ns为一个寻呼帧内的寻呼机会的个数，floor表示下取整运算，mod表示取模运算，m2对应于第一终端设备所属的第一终端设备组的编号。
其中，上述(UE_ID)mod K＝m1，或者floor(UE_ID/(N*Ns))mod K＝m2，只是一种可行的实现方式，基于上述等式，本申请实施例还可以采用其他的计算方式，例如不采用取余计算，而采用相除计算，或者在采用上述等式的基础上进行适当变形，只要能够配置不同终端设备的标识与终端设备组的个数之间的对应关系即可以作为针对不同终端设备的分组方式，此处不做限定。
此外，第一终端设备和网络设备还可以进一步确定至少一个终端设备组的个数。其中，该至少一个终端设备组的个数可以是预先定义的。或者，至少一个终端设备组的个数也可以是网络设备通过信令通知给终端设备，这种情况下，网络设备可以根据终端设备的分布情况或者信道状况或者业务特性等灵活配置至少一个终端设备组的个数。具体地，该信令可以是系统消息，或RRC信令，或MACCE或DCI。其中预先定义的方式可以节省网络设备信令开销，由网络设备信令通知的方式实现更灵活，可以提高网络设备调度的灵活性。
此外，上述终端设备组的确定方式中的各个实施方式可以结合使用。例如，网络设备或者终端设备可以先根据终端设备的DRX周期确定终端设备所属第一集合，然后根据终端设备的标识确定该终端设备属于第一集合中的第一终端设备组等。例如，网络设备或终端设备可以先根据终端设备的寻呼概率确定终端设备所属第一集合，然后根据终端设备的标识确定该终端设备属于第一集合中的第一终端设备组等。
下文将结合上述实施例提供的下行控制信息以及终端设备组的划分方式进一步介绍本发明实施例提供的通信方法和通信装置。需要说明的是，下面各个实施例中用到的相同的定义可以参照上述实施例中的描述，后续实施例不再前述的定义进行赘述。
本申请实施例提出一种通信方法，适用于终端设备的寻呼场景。请参阅图2，本申请实施例提供的通信方法主要包括如下步骤。
201、网络设备确定至少一个终端设备组是否接收下行控制信息调度的寻呼消息。
本发明实施例中并不限定终端设备组包括的终端设备的个数，而且，至少一个终端设备组包括的终端设备的个数可以相同，也可以不相同。
本步骤中，网络设备确定第一下行控制信息中与第一终端设备组对应的字段组,字段组指示至少一个终端设备组是否接收寻呼消息。
本发明实施例中，网络设备可以对终端设备进行分组得到至少一个终端设备组。至少一个终端设备组可以是一个或多个，例如至少一个终端设备组的个数为K，K为正整数。本申请实施例中对于终端设备组的划分方式不做限定，具体的，可以参照上述实施例中的实施方式确定终端设备所属的终端设备组。例如可以根据终端设备的一种或多个属性进行分组。
此外，至少一个终端设备组可以是网络设备根据第一规则确定，而并不由网络设备对终端设备进行分组。
而对于某一终端设备(如第一终端设备)而言，该第一终端设备可以根据第一规则确定其所属的终端设备组。当然，该第一终端设备所属的终端设备组也可以是由网络设备通知给第一终端设备。
进一步的，该第一规则可以是预定义的，也可以是网络设备通知终端设备的。该第一规则可以是与终端设备的一种或多个属性相关。可以理解的是，该第一规则可以是上文中提供各个实施方式中的一种或多种。
本实施例中，网络设备可以以终端设备组为单位，确定该终端设备组是否接收寻呼消息。这样在一个终端设备组内的终端设备的寻呼是同步的，要么同时被寻呼，要么同时不被寻呼，更加有利于网络设备通过下行控制信息指示的方式实现终端设备节能的效果。此外，网络设备以终端设备组为单位的方式进行指示是否接收寻呼消息，相比于以单个终端设备的方式进行指示，可以降低网络设备发送下行控制信息的信令开销，同时可以保证下行控制消息的接收性能。
本申请实施例中，若至少一个终端设备组为一个终端设备组时，网络设备确定该终端设备组确定是否接收寻呼消息。若至少一个终端设备组为多个终端设备组时，网络设备分别确定每个终端设备组是否接收寻呼消息。例如至少一个终端设备组为终端设备组1和终端设备组2时，网络设备确定终端设备组1确定是否接收寻呼消息，还确定终端设备组2是否接收寻呼消息。
202、网络设备在第一寻呼机会(paging occasion，PO)发送下行控制信息(downlink control information，DCI)，下行控制信息用于指示至少一个终端设备组是否接收寻呼消息。
在NR移动通信系统中，PO是一组物理下行控制信道(physical downlink control channel,PDCCH)的监视时机(monitoring occasion)。一个PO可以包含多个时间片段(time slots)，例如，时间片段可以是子帧或正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。网络设备可以在PO中发送用于调度寻呼消息的DCI。另外，一个寻呼帧(paging frame，PF)是一个无线帧，可以包含一个或多个PO或PO的起点。终端设备在监听PO时，先确定PF的位置，然后再确定PF关联的PO的位置。需要说明的是，一个PF关联的PO可以从PF内开始，也可以从PF之后开始。
在本申请实施例中，网络设备确定第一PO，在第一PO通过下行控制信息向至少一个终端设备组指示是否接收寻呼消息。例如下行控制信息指示第一终端设备组接收寻呼消息，则该第一终端设备组内的终端设备都接收寻呼消息，又如下行控制指示第二终端设备组不接收寻呼消息，则该第二终端设备组内的终端设备都不接收寻呼消息。这里属于第二终端设备组的终端设备在接收该下行控制信息后可以不接收该下行控制信息调度的寻呼消息，甚至可以关闭属于第二终端设备组的终端设备接收电路或降低接收电压进入睡眠状态，从而可以节省属于第二终端设备组的终端设备接收该寻呼消息的功耗。
在本申请实施例中，下行控制信息用于指示至少一个终端设备组是否接收寻呼消息，其中，下行控制信息中可以包括指示字段，该指示字段可以用于指示至少一个终端设备组是否接收寻呼消息。例如指示字段可以是下行控制信息中的新增字段，或者该指示字段可以是下行控制信息中的原有功能字段，或者该指示字段可以是下行控制信息中的保留字段，具体实现方式不做限定。该下行控制信息可以参照上文提供的实施例。
203、第一终端设备在第一PO接收下行控制信息，下行控制信息用于指示至少一个终端设备组是否接收下行控制信息调度的寻呼消息。
其中，第一终端设备属于第一终端设备组，网络设备可以确定第一终端设备组是否接收寻呼消息。进一步的，第一终端设备可以根据上文提供的各个实施方式中的一个或多种确定第一终端设备所属的第一终端设备组。
进一步的，第一终端设备和网络设备确定第一终端设备所属的第一终端设备组的规则是相同的，该规则可以是预先定义的，也可以是网络设备为终端设备配置的。
第一终端设备可以确定该第一终端设备所属的第一终端设备组，第一终端设备可以通过下行控制信息确定第一终端设备是否接收寻呼消息。本步骤中的下行控制信息可以参照上文的描述，其具体指示方式也可以参照下文中的详细介绍。
204、第一终端设备根据下行控制信息确定是否接收寻呼消息。
例如网络设备指示第一终端设备组接收寻呼消息，第一终端设备属于第一终端设备组，因此第一终端设备确定该第一终端设备接收寻呼消息，进一步的，第一终端设备接收下行控制信息调度的寻呼消息。
又如网络设备指示第一终端设备不接收寻呼消息，第一终端设备属于第一终端设备组，因此第一终端设备确定不接收寻呼消息。若第一终端设备确定不接收寻呼消息，则第一终端设备不再去接收网络设备后续发送的寻呼消息，从而可以节省终端设备的能耗。
进一步的，步骤204中，第一终端设备确定第一终端设备所属的第一终端设备组，该第一终端设备根据下行控制信息中与第一终端设备组对应的字段组确定是否接收寻呼消息。例如，第一终端设备可以根据下行控制信息中与第一终端设备组对应的字段组或第一比特确定第一终端设备是否接收寻呼消息。第一终端设备能够根据网络设备的配置或者预先定义的规则确定第一终端设备组对应的字段组或第一比特在下行控制信息中的位置。本申请实施例还提出一种通信方法，适用于终端设备的寻呼场景中。上述实施例提供的下行控制信息以及终端设备组也可以应用于本实施例中，因此，相同的内容可以参照上文，不再赘述。此外，本实施中与上述图2对应的实施例相同的内容也可以参照上文的描述。参阅图3所示，本申请实施例提供的通信方法，主要包括如下步骤。
301、网络设备确定至少一个终端设备组是否监听第一PO之后的N个第二PO，N为正整数。
本实施例中，至少一个终端设备组的描述以及如何得到该至少一个终端设备组可以参照上文中的描述。
本申请实施例中,至少一个终端设备可以监听第一PO，网络设备可以确定至少一个终端设备是否监听后续的N个第二PO，其中，N为正整数。N个第二PO是指第一PO之后的PO，例如，N个第二PO可以是从第一PO的下一个PO开始的N个PO，或者是第一PO之后的一个或多个PO之后开始的N个PO，即第一PO和N个第二PO的起始PO之间可以间隔一个或多个PO。本申请实施例中第一PO和第二PO是根据PO所在的时域位置的不同而采用的命名方式，第一PO和第二PO的周期以及其他配置参数可以是相同的，也可以是不同的，本实施例并不限定第一PO和第二PO是否不同。可选地，所述第一PO和所述第二PO为终端设备根据该终端设备的DRX周期和该终端设备的标识确定的PO。
网络设备可以以终端设备组为单位，确定该终端设备组监听N个第二PO，即该终端设备组内的所有终端设备都监听N个第二PO，或者确定该终端设备组不监听N个第二PO，即该终端设备组内的所有终端设备都不监听N个第二PO。这样在一个终端设备组内的终端设备是否监听第二PO是同步的，要么同时监听第二PO，要么同时不监听第二PO，通过下行控制信息指示的方式实现终端设备节能的效果。此外，网络设备以终端设备组为单位的方式进行指示，相比于以终端设备的方式进行指示，可以降低下行控制信息的信令开销，同时可以保证下行控制消息的接收性能。
本申请实施例中，若存在一个终端设备组时，网络设备确定该终端设备组是否监听N个第二PO，若存在多个终端设备组时，网络设备分别对每个终端设备组确定是否监听N个第二PO。例如存在终端设备组1和终端设备组2时，网络设备对终端设备组1确定是否监听N个第二PO，还可以对终端设备组2确定是否监听N个第二PO。
在本申请的一些实施例中，N个第二PO为从第一PO的下一个PO开始的连续N个第二PO。
其中，第一PO的下一个PO即为第1个第二PO，从第1个第二PO直至第N个第二PO即为N个第二PO。
在本申请的一些实施例中，N＝1,N个第二PO为第一PO的下一个PO。
其中，N个第二PO既可以表示1个第二PO，也可以表示多个第二PO，具体可以结合应用场景确定第二PO的个数。N可以为预设值，也可以由网络设备配置。
而且，N个第二PO与第一PO的位置关系可以是预定义的，即网络设备和终端设备可以根据预定义的规则确定N个第二PO从哪里开始，例如，网络设备和终端设备可以根据预定义的规则确定N个第二PO为第一PO的下一个PO开始的N个PO。或者，N个第二PO与第一PO的位置关系可以是网络设备为终端设备配置的。例如，网络设备通过信令通知终端设备，N个第二PO与第一PO之间间隔2个PO,即N个第二PO为从第一PO之后的第三个PO开始的N个PO。
可选地，本实施例中，第一终端设备或第一终端设备组支持扩展非连续接收(extended discontinuous reception,eDRX)时，N个第二PO位于同一个寻呼时间窗(paging time  window,PTW)内。第一PO和N个第二PO可以位于同一个PTW内。第一PO和N个第二PO也可以位于不同的PTW内，例如，N个第二PO所在的PTW为第一PO所在的PTW的下一个PTW。
302、网络设备在第一PO发送下行控制信息，下行控制信息用于指示至少一个终端设备组是否监听N个第二PO。
在本申请实施例中，网络设备确定第一PO，该第一PO可以用于发送下行控制信息，网络设备通过下行控制信息向至少一个终端设备组指示是否监听N个第二PO。例如下行控制信息指示第一终端设备组监听N个第二PO，则该终端设备组内的终端设备都监听N个第二PO，又如下行控制指示第二终端设备组不监听N个第二PO，则第二终端设备组内的终端设备都不监听N个第二PO，因此可以实现终端设备节能的效果。
在本申请实施例中，下行控制信息用于指示至少一个终端设备组是否监听N个第二PO，其中，下行控制信息中可以包括指示字段，该指示字段可以用于指示至少一个终端设备组是否监听N个第二PO。例如指示字段可以是下行控制信息中的新增字段，或者该指示字段可以是下行控制信息中的原有功能字段，或者该指示字段可以是下行控制信息中的保留字段，具体实现方式可以参照上文中的描述。
303、第一终端设备在第一寻呼机会PO接收下行控制信息，下行控制信息用于指示至少一个终端设备组是否监听第一PO之后的N个第二PO，其中，N为正整数。
其中，第一终端设备属于第一终端设备组，网络设备针对第一终端设备组可以确定是否监听N个第二PO，第一终端设备在确定该第一终端设备所属的第一终端设备组之后，第一终端设备接收网络设备针对第一终端设备的下行控制信息，通过下行控制信息确定第一终端设备组是否监听N个第二PO。
304、第一终端设备根据下行控制信息确定是否监听N个第二PO。
本步骤中，第一终端设备可以确定第一终端设备所属的第一终端设备组。
这样，第一终端设备可以根据下行控制信息中与第一终端设备组对应的字段组确定是否监听N个第二PO。其中，下行控制信息中与第一终端设备组对应的字段组用于指示第一终端设备组是否监听N个第二PO。网络设备可以根据该第一终端设备组是否监听N个第二PO来配置下行控制信息中与第一终端设备组对应的字段组，例如该字段组的取值为1指示第一终端设备组监听N个第二PO，该字段组的取值为0指示第一终端设备组不监听N个第二PO。
本实施例中，网络设备指示第一终端设备组监听N个第二PO，则第一终端设备属于第一终端设备组，因此第一终端设备确定监听N个第二PO。又如网络设备指示第一终端设备不监听N个第二PO，则第一终端设备属于第一终端设备组，因此第一终端设备确定不监听N个第二PO。若第一终端设备不监听N个第二PO，则第一终端设备可以不再去监听网络设备后续发送的N个第二PO，从而可以节省终端设备的能耗。
此外，本申请实施例提供的通信方法还可以是上述图2和图3的结合。
例如，步骤301中，网络设备确定至少一个终端设备组是否接收下行控制信息调度的寻呼消息，以及确定该至少一个终端设备组是否监听第一寻呼机会PO之后的N个第二PO。
例如，网络设备确定第一下行控制信息中与第一终端设备组对应的字段组,字段组指示至少一个终端设备组是否接收寻呼消息以及是否监听N个第二PO。
这样，上述实施例中的下行控制信息指示至少一个终端设备组是否接收下行控制信息调度的寻呼消息以及指示该至少一个终端设备组是否监听第一寻呼机会PO之后的N个第二PO。
此外，在步骤304中，第一终端设备可以根据下行控制信息确定是否接收该下行控制信息调度的寻呼消息，以及确定是否监听第一寻呼机会PO之后的N个第二PO。
与上述两个实施例相比，下行控制信息中指示是否接收寻呼消息以及下行控制信息中指示是否监听N个第二P0,如果该下行控制消息指示一个终端设备组不接收寻呼消息，和/或，该下行控制信息指示该终端设备组不监听该N个第二P0，属于该终端设备组的终端设备在接收该下行控制信息后可以不接收该下行控制信息调度的寻呼消息，和/或，属于该终端设备组的终端设备在接收该下行控制信息后可以不监听该N个第二PO，甚至可以关闭该终端设备组的终端设备的接收电路或降低接收电压进入睡眠状态，从而节省终端设备接收该寻呼消息，和/或，监听该N个第二PO的功耗。
为便于更好的理解和实施本申请实施例的上述方案，下面举例相应的应用场景来进行具体说明。
请参阅如图1所示，本申请实施例提供的通信系统可以包括基站和终端设备，其中，基站是网络侧的一种用来发送或接收信号的实体。基站在不同的通信模式下可能有不同的名称，详见前述的举例说明。终端设备可以有多种类型，如终端设备是机器类通信的用户设备。下面实施例中终端设备用UE为例进行说明。
接下来以三个具体的实施例进行详细的举例说明。
实施例一
本实施例包括的步骤如下：
步骤11：基站向UE发送DCI，DCI中指示该UE所属的UE组是否接收后续的寻呼消息。
步骤12：UE接收基站发送的DCI，根据DCI指示确定该UE所属的UE组是否接收后续的寻呼消息。
在上述步骤11和步骤12中，该DCI包含寻呼消息的调度信息时，该DCI包含上述指示该UE所属的UE组是否接收后续的寻呼消息。
例如用于，调度寻呼消息的DCI和携带短消息的DCI都采用的都是DCI format 1_0，并且DCI format 1_0的冗余校验(cyclic redundancy check，CRC)是通过寻呼无线网络临时标识(paging-radio network tempory identity，P-RNTI)加扰。短消息中携带系统消息变更指示。所以UE在PO处监听的DCI可能有3种情况，第一种情况是该DCI只包括寻呼消息的调度信息，第二种情况是该DCI中只包括短消息，第三种情况是该DCI中包括寻呼消息的调度信息和短消息。为了区分这三种情况，DCI中包括短消息指示字段(short message indicator)来进行指示，具体如下表1所示。
表1
Figure PCTCN2021101972-appb-000001
如果DCI中只包括短消息，UE接收到该DCI后不涉及寻呼消息的接收，因此也就不指示是否接收后续的寻呼消息。该DCI包含寻呼消息的调度信息时，该DCI还指示是否接收寻呼消息，即在DCI包括寻呼消息的调度信息时，该DCI还用于指示终端设备组是否接收寻呼消息。
DCI的具体指示方式有多种，接下来进行举例说明。
一种可实现方式中，DCI中指示各个UE组是否接收后续的寻呼消息。此时DCI中包括K1个比特，比特位置和UE组之间的映射关系可以是预设的，比如K1比特中的最低比特位对应组标识最小的UE组，K1个比特中的最高比特位对应组标识最大的UE组，每个比特位的值为第一值时表示该比特位对应的UE组接收DCI调度的寻呼消息，每个比特位的值为第二值时表示该比特位对应的UE组不接收DCI调度的寻呼消息，例如第一值为1，第二值为0，或者第一值为0，第二值为1。如图4所示，UE1的UE_Id为A，UE2的UE_Id为B，基站在一个DRX周期内的一个PO内可以发送DCI，该DCI有两个比特，即K1＝2，其中一个比特为0，指示UE1所属的UE组不接收DCI调度的寻呼消息，另一个比特为1，指示UE2所属的UE组接收DCI调度的寻呼消息。对于UE1所属的UE组来说，通过DCI提前通知UE1所属的UE组，后续的寻呼消息中不携带该UE组的标识，因此，UE1所属的UE组不接收寻呼消息，从而可以节省UE1接收寻呼消息所需的功耗。
一个实施方式中，DCI中包括的K1个比特可以是通过DCI中的新增字段或者新增比特进行指示，也可以利用已有DCI格式中的冗余字段或者部分字段的冗余状态来指示各个UE组是否接收后续的寻呼消息。例如在NR系统中用于，寻呼消息的DCI的格式为DCI format1-0，CRC通过P-RNTI加扰，该DCI中主要包括短消息指示(short message indicator)域、短消息(short messages)域以及其他比特域。其中，其他比特域中包括未被使用的比特，也包括已经被使用的比特。本申请实施例中可以使用短消息指示域、短消息域和DCI中高比特位的预留比特来指示各个UE组是否接收后续的寻呼消息。
接下来针对上述步骤11和步骤12中UE的分组方式进行详细说明。
例如，UE可以根据以下参数中的至少一项确定该UE对应的UE组：DRX周期(cycle)、寻呼概率、上下行业务触发类型和UE标识。
1、DRX周期，例如相同DRX周期的UE为一个UE组。
UE的DRX周期由网络设备配置，对于核心网寻呼(CN paging)，网络设备通过非接入层(non-access stratum,NAS)信令将DRX周期通知给UE，对于无线接入网寻呼(RAN paging)，网络设备通过无线资源控制(radio resource control，RRC)消息将DRX周期通知给UE，例如，可以通过RRC释放消息将DRX周期通知给UE。
一个实施方式中，UE和网络设备可以根据DRX周期的值确定UE所属的UE组，例如NR系统中的DRX周期包括{rf32,rf64,rf128,rf256},rf表示无线帧，UE的DRX周期的值为32rf，则该UE对应的UE组为组1，依次类推。其中，rf32是协议中DRX周期的配置值，例如，rf32可以为字符串。当配置值为rf32的时候，表示DRX周期为32rf，即32个无线帧(radio frame)。
其中，在NR系统中，CN Paging用于在跟踪区(tracking area)中寻呼处于RRC_非激活(inactive)或者RRC_空闲(idle)状态的终端设备。在NR系统中，RAN Paging用于在无线接入网通知区(RAN-based Notification Area，RNA)中寻呼处于RRC离线状态的UE。
2、寻呼概率，例如相同寻呼概率的UE为一个UE组。
对于CN paging，核心网通过NAS通知UE寻呼概率P，基站广播寻呼概率门限，UE根据寻呼概率和寻呼概率门限确定该UE所属的UE组。
对于RAN paging，通过RRC消息，比如RRC释放消息通知UE寻呼概率P，基站广播寻呼概率门限，UE根据寻呼概率和概率门限确定该UE所属的UE组。
UE所属的UE组的示例说明如下，假设基站广播3个寻呼概率门限：th1,th2,th3，则可以通过寻呼概率门限将所有的UE分为4个UE组，其中，P<th1的UE为UE组1，th1≤P<th2的UE为UE组2，th2≤P<th3的UE为组3，P≥th3的UE为组4。
3、上下行业务触发类型，例如相同的上下行业务触发类型的UE为一个UE组。
本申请实施例中，根据终端设备的类型确定终端设备的业务特征，例如业务特征可以包括上下行业务触发类型。
例如，终端设备的类型有多种，例如终端设备可以是传感器类型的终端设备，主要业务类型为上行业务触发类型，被下行寻呼的概率较低，比如水表，烟感报警器等。因此，可以根据水表的业务特征和烟感报警器的业务特征将该水表和烟感报警器的终端设备划分至同一类别的终端设备组，且该类别的终端设备组中的终端设备会被寻呼的概率较低。又如，终端设备可以是手机或者电脑时，业务特征包括上行触发和下行寻呼，即会被寻呼的概率较高，因此，可以根据手机的业务特征和电脑的业务特征将该手机和电脑划分为同一类别的终端设备组，且该类别中的终端设备组会被寻呼的概率较高。
具体地，对于CN paging，核心网设备可以通过NAS信令向UE发送该UE所属的UE组。其中，核心网设备是一种承担终端移动性管理的设备，包括各种通信制式中的核心网设备，例如包括但不限于：4G网络中的移动性管理实体(mobility management entity，MME)、5G网络中的接入管理功能实体(access management function，AMF)等。核心网设备可以是物理实体，也可以是逻辑功能实体，还可以是设置于物理实体内的芯片。
对于RAN paging，通过RRC消息，比如RRC释放消息通知UE所属的UE组。
UE所属的UE组的示例说明如下，业务特征为上行业务触发类型的UE属于一个UE组， 业务特征为下行业务触发类型的UE属于一个UE组。
4、UE标识。
基于终端设备的设备标识(例如UE_ID)将至少一个终端设备划分为M个分组，更具体地，通过对终端设备的UE_ID进行取模计算，例如，(UE_ID)mod K＝m，或者floor(UE_ID/(N*Ns))mod K＝m，其中，M为分组的个数，m为(UE_ID)对K取模后的余数，即m为分组对应的编号,N为一个DRX周期中寻呼帧(paging frame，PF)的个数，Ns为一个寻呼帧内的PO的个数，N和Ns可以由网络设备配置。对于NR系统，UE_ID可以为(5G-S-TMSI)mod 1024。例如，m＝1，表示该终端设备属于第一终端设备组，m＝2，该终端设备表示第二终端设备组。
需要说明的是，这里对于UE_ID的具体实现形式不做限定，不局限于本实施例中列举的5G-S-TMSI，NR系统的后续演进或者未来系统中可以采用其它形式，此处不做限定。
可以理解的是，本申请实施例中可以使用UE的多个参数确定该UE对应的终端设备组。如下表2所示，根据DRX周期和UE标识确定分组，例如可以先根据DRX周期分为4个集合，然后将每个集合再根据UE_ID分为2个UE组，将UE一共划分成了8个UE组。
表2
Figure PCTCN2021101972-appb-000002
其中，/表示相处运算，*表示相乘运算，floor表示下取整运算，mod表示取模运算。
需要说明的是，DCI还可以用于指示是否监听后续的寻呼消息，例如可以针对单个UE进行指示，但是考虑到DCI的开销，本申请实施例中可以确定UE所属的UE组，然后按照UE组指示是否监听后续的寻呼消息。例如，划分到同一个终端设备组内的UE的业务特征相似，每个组内UE数越少越好，或者说UE的分组数越多越好。
综上说明可知，本申请实施例中，可以将多个参数结合起来确定UE所属的UE组，可以使得每个组内UE的业务相似，且多个组内UE数量相近，结合本实施例提供的DCI的指示方式，使得UE更易于达到节能的目的。
如下表3所示，也可以根据寻呼概率和UE标识确定UE所属的UE组，可以先根据寻呼概率分为4个集合(set)，根据寻呼概率划分的集合数满足寻呼概率的门限数+1，总的UE组数由网络设备配置，每个集合内的UE组数由总的UE组数和集合数确定，比如，每个集合内的UE组数满足总的UE组数/集合数。然后根据UE标识和该集合的组数确定在该集合 内的组索引，比如，该集合内的组索引满足如下关系：pg＝floor(UE_ID/(N*Ns))mod Np，N为一个DRX周期中PF的个数，Ns为一个PF内的PO的个数，Np为该集合内的UE组数，N，Ns和Np可以由网络设备配置，pg为该集合内的组索引，根据上式确定的pg的取值为0,1,2,…,Np-1中的一个值,对于NR系统，UE_ID可以为5G-S-TMSImod 1024；最后根据该集合内的组索引和该集合的索引确定该UE所属的UE组。下表为一个具体的示例，该示例中网络设备配置了3个寻呼概率门限，按照寻呼概率分为4个集合，总的UE组数为8,每个集合内的UE组数为8/4＝2，即对于集合1至集合4,Np＝2。

其中，/表示相处运算，*表示相乘运算，＜表示小于，≤表示小于或等于，＞表示大于，floor表示下取整运算，mod表示取模运算。
需要说明的是，上述表格中用到的相同的参数可以参照上述实施例中的描述。下述为根据寻呼概率和UE标识确定分组UE所属的UE组的另一个示例，根据寻呼概率划分的集合数满足寻呼概率的门限数+1，每个集合内的UE组数由网络设备配置，每个集合内的UE组数可以相同，也可以不同。网络设备或者UE根据UE的寻呼概率和寻呼概率门限确定UE所属的集合；然后根据UE标识和该集合的组数确定在该集合内的组索引，比如，该集合内的组索引满足如下关系：pg＝floor(UE_ID/(N*Ns))mod Np，pg表示集合内的组索引,N为一个DRX周期中PF的个数，Ns为一个PF内的PO的个数，Np为该集合内的UE组数，N，Ns和Np可以由网络设备配置，根据上式确定的pg的取值为0,1,2,…,Np-1中的一个值,对于NR系统，UE_ID可以为5G-S-TMSImod 1024；最后根据该集合内的组索引和该集合的索引确定该UE所属的UE组。下表4为一个具体的示例，该示例中网络设备配置了3个寻呼概率门限，按照寻呼概率分为4个集合，集合1配置的组数为2组，即对于集合1，Np＝2，集合2配置的组数为3组，对于集合2，Np＝3，集合3配置的组数为4组，对于集合3，Np＝4，集合4配置的组数为5组，对于集合4，Np＝5。

其中，/表示相处运算，*表示相乘运算，＜表示小于，≤表示小于或等于，＞表示大于，floor表示下取整运算，mod表示取模运算。
需要说明的是，上述表格中用到的相同的参数可以参照上述实施例中的描述。
通过前述的举例说明可知，本实施例中网络设备通过确定UE所在的UE组，DCI中指示各个UE组是否接收后续的寻呼消息，可以避免终端设备在接收寻呼信息后才确定自己没有被寻呼，降低该终端设备接收寻呼消息的功耗。
网络设备通过在DCI中指示各个UE组是否接收后续的寻呼消息。具体网络设备和UE可以根据以下参数至少一项确定该UE对应的UE组：DRX周期，寻呼概率，上下行业务触发类型，UE标识。本实施例中在确定UE所属的UE组时考虑到终端设备的业务特征，例如终端设备的DRX周期，终端设备的寻呼概率，终端设备业务触发类型等。例如，终端设备的业务触发类型相似，寻呼概率相等或者接近，或者DRX周期相同，这样在一个分组的终端设备的寻呼比较同步，要么同时被寻呼，要么同时不被寻呼，更加有利于终端设备实现节能目的。否则，如果一个UE组内既有被寻呼的UE，也有未被寻呼的UE，极端情况下，出现只有一个UE被寻呼而大多数UE没有寻呼的情况，难以通过DCI指示的方式达到节能目的。
实施例二
本实施例包括的步骤如下：
步骤21、基站向UE发送DCI，DCI中指示该UE所属的UE组是否接收后续的寻呼消息，和该UE所属的UE组是否监听后续的N个PO。
步骤22、UE接收基站发送的DCI，根据DCI指示确定该UE所属的UE组是否接收后续的寻呼消息，和该UE所属的UE组是否监听后续的N个PO。
接下来针对步骤21和步骤22中UE的分组方式进行详细说明，该DCI包含寻呼调度时包含上述指示。
其中，N由网络设备配置或者网络设备与终端设备共同确定。
DCI的具体指示方式如下：DCI中指示各个UE组是否接收后续的寻呼消息，和该UE所属的UE组是否监听后续的N个PO。此时DCI中包括K2个比特。
实现方式1-1：K2满足t1+t2，t2等于t1，t1为K2个比特中位于低比特位的t1个比特，t2为K2个比特中位于高比特位的t2个比特，或者，t1为K2个比特中位于高比特位的t1个比特，t2为K2个比特中位于低比特位的t2个比特。t1个比特和UE组之间的映射关系可以是预设的，t2个比特和UE组之间的映射关系可以是预设的，例如，t1个比特中每个比特位的值为第一值时表示该比特位对应的UE组接收DCI调度的寻呼消息，t1个比特中每个比特位的值为第二值时表示该比特位对应的UE组不接收DCI调度的寻呼消息。例如第一值为1，第二值为0，或者第一值为0，第二值为1。
类似地，t2个比特和UE组之间的映射关系可以是预设的，比如t2个比特每个比特位的值为第一值时表示该比特位对应的UE组监听DCI后续的N个PO，t2个比特中每个比特位的值为第二值时表示该比特位对应的UE组不监听DCI后续的N个PO。例如第一值为1，第二值为0，或者第一值为0，第二值为1。
例如图5所示，UE1的UE_ID为A，UE2的UE_ID为B，UE3的UE_ID为C，在一个RDX周期内，在一个PO内可以发送DCI。K2＝6,t1＝t2＝3，该DCI有六个比特，从左至右的六个比特取值分别为010001，第1个比特为0，指示UE1所属的UE组不接收DCI调度的寻呼消息，第2个比特为1，指示UE2所属的UE组接收DCI调度的寻呼消息，第3个比特为0，指示UE3所属的UE组不接收DCI调度的寻呼消息，第4个比特为0，指示UE1所属的UE组不监听DCI后续的一个PO，第5个比特为0，指示UE2所属的UE组不监听DCI后续的一个PO，第6个比特为1，指示UE3所属的UE组监听DCI后续的一个PO。例如，对于UE1和UE3分别所属的UE组来说，通过DCI提前通知后续的寻呼消息中不携带该UE组的标识，可以节省接收寻呼消息的功耗，此外对于UE1和UE2分别所属的UE组，通过DCI提前通知不监听DCI之后的一个PO，可以节省监听DCI之后的一个PO的功耗。
实现方式1-2：K2满足t1+t2，t2可以小于t1，t1个比特用于指示UE组是否接收DCI调度的寻呼消息，t2个比特用于指示不接收DCI调度的寻呼消息的UE组，是否监听DCI之后的N个PO。相比于实现方式1-1，好处是可以节省信令开销。如图6所示，t1＝3,t2＝2。该DCI有五个比特，从左至右的五个比特取值分别为01001，第1个比特为0，指示UE1所属的UE组不接收DCI调度的寻呼消息，第2个比特为1，指示UE2所属的UE组接收DCI调度的寻呼消息，第3个比特为0，指示UE3所属的UE组不接收DCI调度的寻呼消息，第4个比特为0，指示UE1所属的UE组不监听DCI后续的一个PO，第5个比特为1，指示UE3所属的UE组监听DCI后续的一个PO。
实现方式2，K2满足2*t3，每2个比特和UE组之间的映射关系可以是预设的，比如每2个比特中低比特位的值为第一值时表示该比特位对应的UE组接收DCI调度的寻呼消息，每2个比特中低比特位的值为第二值时表示该比特位对应的UE组不接收DCI调度的寻呼消息。例如，第一值为1，第二值为0，或者第一值为0，第二值为1。每2个比特中高比特 位的值为第一值时表示该比特位对应的UE组监听DCI后续的N个PO，每2个比特中高比特位的值为第二值时表示该比特位对应的UE组监听DCI后续的N个PO。如图7所示，K2＝6,t3＝3，该DCI有六个比特，从左至右的六个比特取值分别为001001，第1个比特为0，指示UE1所属的UE组不接收DCI调度的寻呼消息，第2个比特为0，指示UE1所属的UE组不监听DCI后续的一个PO，第3个比特为1，指示UE2所属的UE组接收DCI调度的寻呼消息，第4个比特为0，指示UE2所属的UE组不监听DCI后续的一个PO，第5个比特为0，指示UE3所属的UE组不接收DCI调度的寻呼消息，第6个比特为1，指示UE3所属的UE组监听DCI后续的一个PO。对于UE1和UE3分别所属的UE组来说，通过DCI提前通知后续的寻呼消息中不携带该UE组的标识，可以节省接收寻呼消息的功耗，此外对于UE1和UE2分别所属的UE组，通过DCI提前通知不监听DCI之后的一个PO，可以节省监听DCI之后的一个PO的功耗。
需要说明的是，实施例二和实施例一中都可以是通过新增字段或者新增比特进行指示，也可以利用已有DCI格式中的冗余字段或者部分字段的冗余状态来指示各个UE组是否接收后续的寻呼消息。
UE具体的分组方式和实施例一相同，这里不在赘述。
通过前述举例说明可知，本实施例中网络设备通过确定UE所在的UE组，DCI中指示各个UE组是否接收后续的寻呼消息，可以避免终端设备在接收了寻呼信息后才确定自己没有被寻呼，降低终端设备接收寻呼消息的功耗。同时DCI中指示各个UE组是否监听DCI之后的后续N个PO，可以避免终端设备在监听了PO之后才确定自己没有被寻呼，降低该终端设备监听N个PO的功耗。
网络设备通过确定UE所在的UE组，DCI中指示各个UE组是否接收后续的寻呼消息。UE可以根据以下参数至少一项确定该UE对应的UE组：DRX周期，寻呼概率，上下行业务触发类型，UE标识。本实施例中在确定UE所属的UE组时考虑到终端设备的业务特征，例如终端设备的DRX周期，终端设备的寻呼概率，终端设备业务触发类型等，终端设备业务触发类型相似，寻呼概率相等或者接近，或者DRX周期相同，这样在一个分组的终端寻呼比较同步，要么同时被寻呼，要么同时不被寻呼，更加有利于网络实现节能目的。否则，如果一个UE组内既有被寻呼的UE，也有未被寻呼的UE，极端情况下，出现只有一个UE被寻呼而大多数UE没有寻呼的情况，网络设备难以通过DCI指示的方式达到节能目的。
实施例三
本实施例包括的步骤如下：
步骤31、基站向UE发送DCI，DCI中指示该UE所属的UE组是否监听后续的N个PO。
步骤32、UE接收基站发送的DCI，根据DCI指示确定该UE所属的UE组是否监听后续的N个PO。
接下来针对步骤31和步骤32中UE的分组方式进行详细说明，该DCI包含寻呼调度时包含上述指示。
其中，N由网络设备配置或者网络设备与终端设备共同确定。
DCI的具体指示方式如下：DCI中指示各个UE组是否监听后续的N个PO。
如图8所示，此时DCI中包括K3个比特，比特位置和UE组之间的映射关系可以是预 设的，比如K3比特中的最低比特位对应组标识最小的UE组，多个比特中的最高比特位对应组标识最大的UE组，每个比特位的值为第一值时表示该比特位对应的UE组监听DCI之后的N个PO，每个比特位的值为第二值时表示该比特位对应的UE组不监听DCI之后的N个PO。第一值为1，第二值为0，或者第一值为0，第二值为1。如图8所示，K3＝3,第1个比特为0，指示UE1所属的UE组不监听DCI后续的一个PO，第5个比特为0，指示UE2所属的UE组不监听DCI后续的一个PO，第6个比特为1，指示UE3所属的UE组监听DCI后续的一个PO。对于UE1和UE2分别所属的UE组来说，通过DCI提前通知不监听DCI之后的一个PO，可以节省监听DCI之后的一个PO的功耗。
实施例三和实施例一都可以是通过新增字段或者新增比特进行指示，也可以利用已有DCI格式中冗余字段或者部分字段的冗余状态来指示各个UE组是否接收后续的寻呼消息。
UE具体的分组方式和实施例一相同，这里不在赘述。
本实施例中网络设备通过确定UE所在的UE组，DCI中指示各个UE组是否监听DCI之后的后续N个PO，可以避免部分终端设备在监听了PO之后才确定自己没有被寻呼，降低该部分终端设备监听N个PO的功耗。
通过前述的举例说明可知，网络设备通过确定UE所在的UE组，DCI中指示各个UE组是否接收后续的寻呼消息。UE可以根据以下参数至少一项确定该UE对应的UE组：DRX周期，寻呼概率，上下行业务触发类型，UE标识。本实施例中在确定UE所属的UE组时考虑到终端设备的业务特征，例如终端设备的DRX周期，终端设备的寻呼概率，终端设备业务触发类型等，终端设备业务触发类型相似，寻呼概率相等或者接近，或者DRX周期相同，这样在一个分组的终端寻呼比较同步，要么同时被寻呼，要么同时不被寻呼，更加有利于网络实现节能目的。否则，如果一个UE组内既有被寻呼的UE，也有未被寻呼的UE，极端情况下，出现只有一个UE被寻呼而大多数UE没有寻呼的情况，网络设备难以通过DCI指示的方式达到节能目的。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
