本申请涉及通信领域，特别是涉及一种DRX周期长度调整方法、装置、设备以及存储介质。

多媒体广播多播服务(Multimedia Broadcast Multicast Service，MBMS)是一种通过共享网络资源从一个数据源向多个用户设备传送数据的技术，采用MBMS业务能有效地利用网络资源，实现较高速率多媒体广播业务和组播业务。随着通信网络的演进，在新空口(new radio，NR)中逐渐引入组播和广播业务，例如车联网、工业互联网等业务中均需要引入多播业务支持多终端的接入。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
首先为方便理解本申请实施描述的技术方案，对本申请实施例涉及的术语进行解释说明：
(1)单播
单播可以一个发送端和一个接收端之间进行的通信。例如，可以是终端设备与接入网设备之间进行的点对点通信。
(2)多播
区别于单播通信，多播可以是一个发送端和多个接收端之间进行的通信。多播可以包括组播和广播。例如，基站可以通过广播方式发送系统消息，或，通过组播方式向用户设备(user equipment，UE)群组发送下行消息。
(3)DRX周期
参考图1，DRX周期包括“On Duration”和“Opportunity for DRX”。在“On Duration”内，UE处于唤醒状态，可以监听PDCCH。在“Opportunity for DRX”内，UE为了省电进入休眠状态，不进行PDCCH的监听。可以理解的是，“Opportunity for DRX”时间越长，UE的功率消耗就越低。
根据“Opportunity for DRX”的时长可以将DRX周期分为长DRX周期(long DRX cycle)和短DRX周期(short DRX cycle)。其中，长DRX周期包括的“Opportunity for DRX”长于短DRX周期包括的“Opportunity for DRX”。
本申请实施例所述的方法适用于图2所示的通信系统。图2给出了本申请提供的技术方案所适用的一种通信系统的示意图，该通信系统可以包括一个或多个接入网设备100(图1仅示出了1个)以及一个或多个终端设备200。图2仅为示意图，并不构成对本申请提供的技术方案的适用场景的限定。
接入网设备100可以是传输接收节点(transmission reception point，TRP)、基站、中继站或接入点等。接入网设备100可以是5G通信系统中的接入网设备或未来演进网络中的接入网设备；还可以是可穿戴设备或车载设备等。另外还可以是：全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是长期演进(long term evolution，LTE)中的eNB(evolutional NB)或eNodeB(evolutional NodeB)。接入网设备100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。
终端设备200可以是用户设备(user equipment，UE)、接入终端、UE单元、UE站、移动站、移 动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。接入终端可以是蜂窝电话、无绳电话、会话发起协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端或未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端等。
在NR中定义了DRX相关的介质访问控制层控制元素(media Access Control control element，MAC CE)，可以称为DRX command MAC CE，通过MAC CE指示终端设备进行DRX周期长度切换。具体地，指示DRX周期长度切换的MAC CE包括DRX command MAC CE以及long DRX MAC CE。终端设备接收接入网设备发送的DRX command MAC CE后，可以从long DRX cycle切换为short DRX cycle。终端设备接收接入网设备发送的long DRX MAC CE后从short DRX cycle切换为long DRX cycle。
NR引入多播业务后，多播和单播是相互独立的。终端设备可以根据DRX command MAC CE和long DRX MAC CE来识别终端业务的接收使用long DRX cycle还是short DRX cycle，但是，无法识别DRX command MAC CE和long DRX MAC CE是用于多播业务的接收还是单播业务的接收，使得终端设备的行为出现混乱，无法正确进行DRX周期长度切换。
基于此，本申请实施例提供一种DRX周期长度调整方法，能够区分MAC CE是用于多播业务的接收还是单播业务的接收，实现多播业务和单播业务针对DRX command MAC CE的隔离配置，避免终端设备的行为出现混乱，指示终端进行DRX周期长度切换。如图3所示，该方法包括以下步骤：
301、终端设备接收接入网设备发送的MAC层控制信息；
其中，MAC层控制信息可以是与DRX相关的MAC层控制信息，例如，可以是DRX command MAC CE或者long DRX command MAC CE。
具体实现中，终端设备接收MAC sub PDU，MAC sub PDU包括消息头(subheader)和载荷(payload)。Subheader中包含逻辑信道标识，payload中包含MAC层控制信息，Subheader中的逻辑信道标识可以指示payload中包含的MAC层控制信息的类型。例如，消息头中的逻辑信道标识可以指示payload中包含的是DRX command MAC CE还是long DRX command MAC CE。其中，逻辑信道标识可以是logic channel Identity document，简称LCID。也就是说，终端设备通过接收MAC sub PDU可以获取上述MAC层控制信息。
示例性的，当Subheader中的逻辑信道标识为“1”，表明MAC sub协议数据单元(protocol data unit，PDU)的payload中包含的是DRX command MAC CE。当Subheader中的逻辑信道标识为“0”，表明MAC sub PDU的payload中包含的是long DRX command MAC CE。
302、终端设备确定MAC层控制信息适用的终端业务，终端业务包括多播业务或单播业务；
本申请实施例中，对单播业务和多播业务进行隔离配置，终端设备接收MAC层控制信息后，可以确定MAC层控制信息适用的是多播业务还是单播业务，以便根据MAC层控制信息对相应业务的接收进行DRX周期长度切换。通过确定MAC层控制信息使用的终端业务，可以正确进行DRX周期长度切换，避免UE行为混乱导致的切换错误。
其中，多播业务可以包括组播和广播，单播业务可以是终端设备与接入网设备之间的点对点通信业务。
具体实现中，终端设备可以根据MAC层控制信息中携带的内容来确定MAC层控制信息适用的是多播业务还是单播业务，或者，可以根据MAC层控制信息对应的消息头中携带的内容确定MAC层控制信息适用的是多播业务还是单播业务，也可以根据上述消息头的接收资源来确定MAC层控制信息适用的是多播业务还是单播业务。其中，MAC层控制信息对应的消息头即承载该MAC层控制信息的payload对应的subheader。
一种可能的实现方式中，MAC层控制信息中携带的内容可以是MAC层控制信息中指定字段，例如，预留字段、复用已有字段等。消息头中携带的内容可以是消息头中指定字段，例如，预留字段、复用已有字段等。消息头的接收资源可以是承载该消息头的物理下行数据信道(physical downlink shared channel，PDSCH)，或者，也可以是PDSCH的加扰标识。其中，加扰标识可以是无线网络临时标识(radio network temporary identifier，RNTI)。
303、终端设备对MAC层控制信息适用的终端业务的接收进行DRX周期长度调整。
具体实现中，终端设备可以确定上述MAC层控制信息指示的DRX周期，例如，确定MAC层控制信息指示的是long DRX cycle还是short DRX cycle。也就是说确定步骤301接收到的MAC CE(MAC层控制信息)是DRX command MAC CE还是long DRX command MAC CE。
示例性的，终端设备可以根据MAC层控制信息对应的消息头中的逻辑信道标识确定MAC层控制信息是DRX相关的MAC CE，例如，根据消息头中的逻辑信道标识确定MAC层控制信息是DRX  command MAC CE还是long DRX command MAC CE。
本申请实施例提供的方法中，终端设备在接收接入网设备发送的MAC层控制信息后，可以确定MAC层控制信息适用的是多播业务还是单播业务，从而有区别性地对多播业务或单播业务的接收执行DRX周期长度切换操作，可以实现对多播业务和单播业务的隔离配置，避免终端设备盲目进行DRX周期长度切换，保证DRX周期长度切换与业务类型的准确匹配。
在本申请的另一实施例中，终端设备可以基于逻辑信道标识指示MAC层控制信息的类型，以便终端设备进行正确的DRX周期长度调整。示例性的，参考图4，前文所述的终端设备对终端业务的接收进行DRX周期长度调整的具体实现包括以下步骤：
401、根据MAC层控制信息对应的消息头确定逻辑信道标识；逻辑信道标识用于指示MAC层控制信息的类型；
具体实现中，终端设备可以解析MAC层控制信息对应的消息头获得逻辑信道标识，从而可以根据其中的逻辑信道标识确定MAC层控制信息的类型。其中，MAC层控制信息的类型包括：DRX相关的MAC CE、DRX command MAC CE或者long DRX command MAC CE。
示例性的，参考图5，终端设备接收MAC sub PDU，MAC sub PDU包括消息头和payload。消息头包括逻辑信道标识，payload包括MAC层控制信息。终端设备可以根据消息头中的逻辑信道标识确定MAC层控制信息的类型。
402、若逻辑信道标识为DRX相关的逻辑信道标识，则根据MAC层控制信息对终端业务的接收进行DRX周期长度调整。
具体实现中，终端设备识别逻辑信道标识为DRX相关的逻辑信道标识，则确定上述MAC层控制信息是DRX相关的MAC CE，用于指示终端设备进行DRX周期长度调整。基于此，终端设备则可以根据MAC层控制信息对MAC层控制信息适用的终端业务的接收进行DRX周期长度调整。
一种可能的实现方式中，终端设备支持的DRX周期可以分为long DRX cycle和short DRX cycle。
上述步骤402涉及的对终端业务进行DRX周期长度调整，包括：将MAC层控制信息适用的终端业务对应的DRX周期切换为MAC层控制信息指示的DRX周期。
例如，根据LCID确定MAC层控制信息指示的是long DRX cycle，若MAC层控制信息适用的是多播业务，则将多播业务的DRX周期切换为long DRX cycle，后续使用long DRX cycle进行多播业务的接收；若MAC层控制信息适用的是单播业务，则将单播业务对应的DRX周期切换为long DRX cycle，后续使用long DRX cycle进行单播业务的接收。
当根据LCID确定MAC层控制信息指示的是short DRX cycle，若MAC层控制信息适用的是多播业务，则将多播业务的DRX周期切换为short DRX cycle，后续使用short DRX cycle进行多播业务的接收；若MAC层控制信息适用的是单播业务，则将单播业务的DRX周期切换为short DRX cycle，后续使用short DRX cycle进行单播业务的接收。
在本申请的另一实施例中，逻辑信道标识不仅可以指示MAC层控制信息的类型，也可以指示终端业务的类型。终端设备可以根据逻辑信道标识确定MAC层控制信息适用的终端业务。
具体实现中，单播业务对应的逻辑信道标识与多播业务对应的逻辑信道标识不同。也就是说，为了区分单播业务、多播业务，给单播业务对应的MAC层控制信息、多播业务对应的MAC层控制信息定义了不同的逻辑信道标识。终端设备可以通过消息头中的逻辑信道标识识别payload中的MAC层控制信息适用的是单播业务还是多播业务。
示例性的，为多播业务定义了逻辑信道标识A和逻辑信道B，其中，逻辑信道标识A用于指示适用于多播业务的DRX command MAC CE，逻辑信道B用于指示适用于多播业务的long DRX command MAC CE。
单播业务可以沿用当前DRX相关的MAC CE，例如，单播业务对应逻辑信道标识C和逻辑信道D，其中，逻辑信道标识C用于指示适用于单播业务的DRX command MAC CE，逻辑信道D用于指示适用于单播业务的long DRX command MAC CE。
需要说明的是，适用于多播业务的MAC CE可以称为MBS DRX command MAC CE或MBS Long DRX command MAC CE。
在一种可能的实现方式中，终端设备根据逻辑信道标识确定MAC层控制信息适用的业务类型后，可以基于上述MAC层控制信息对该类型的所有业务的接收进行DRX周期长度调整。
例如，网络设备可以为终端设备配置一个或多个多播业务，若MAC层控制信息适用的是多播业务，终端设备则可以对当前所配置的所有多播业务的接收进行DRX周期长度调整。
网络设备也可以为终端设备配置一个或多个单播业务，若MAC层控制信息适用的是单播业务，终 端设备则可以对当前所配置的所有单播业务的接收进行DRX周期长度调整。
本申请实施例提供的方法中，通过逻辑信道标识同时指示终端业务以及MAC层控制信息的类型，终端设备获取逻辑信道标识后不仅可以识别出MAC层控制信息的类型，还可以确定MAC层控制信息适用的类型，用较少的字段开销实现了对单播业务和多播业务的隔离配置，降低了终端设备的处理复杂度。
在本申请的另一实施例中，MAC层控制信息对应的消息头中携带指示终端业务的字段，终端设备可以根据消息头确定MAC层控制信息适用的是多播业务还是单播业务。示例性的，终端设备可以根据MAC层控制信息对应的消息头确定第一信息；第一信息用于指示该MAC层控制信息适用单播业务，或该MAC层控制信息适用多播业务；从而终端设备可以根据第一信息确定MAC层控制信息适用的终端业务。
示例性的，第一信息包含在MAC层控制信息对应的消息头中，终端设备可以从消息头中获取第一信息。可选的，第一信息在消息头的子头中。
在一种可能的实现方式中，第一信息可以是MAC层控制信息对应的消息头中特定字段上填充的信息。示例性的，参考图6，MAC层控制信息对应的消息头包括8比特，其中，前两个比特为预留字节R。本申请实施例可以使用消息头中的预留字节来指示终端业务。
例如，在消息头中的第二个预留字段填充第一信息T。当T＝0时，表示MAC层控制信息适用于单播业务；当T＝1时，表示MAC层控制信息。
需要说明的是，本申请实施例对第一信息所在的字段不作具体限定，第一信息可以是消息头中的一比特也可以是消息头中的多个比特。
在一种可能的实现方式中，终端设备根据第一信息确定MAC层控制信息适用的业务类型后，根据MAC层控制信息对该类型下所有业务的接收进行DRX周期长度调整。
本申请实施例提供的方法中，通过逻辑信道标识指示MAC层控制信息的类型，通过消息头中的特定字段来指示终端业务。终端设备获取逻辑信道标识后可以识别出MAC层控制信息的类型，还可以根据消息头中的特定字段确定MAC层控制信息适用的类型，用不同字段实现单播业务和多播业务的隔离配置，避免终端设备盲目进行DRX周期长度调整。
在本申请的另一实施例中，可以通过调度MAC层控制信息的无线网络临时标识来指示终端业务。示例性的，终端设备可以确定调度MAC层控制信息的无线网络临时标识，根据无线网络临时标识确定MAC层控制信息适用的终端业务。
其中，调度MAC层控制信息的无线网络临时标识用于加扰PDSCH，该PDSCH用于承载下行消息，该下行消息包括消息头和payload。其中，payload包含上述MAC层控制信息。
一种可能的实现方式中，接入网设备可以通过不同的无线网络临时标识加扰多播业务的调度信息和单播业务的调度信息。其中，用于加扰多播业务的调度信息的无线网络临时标识可以称为C-RNTI，用于加扰单播业务的调度信息的无线网络临时标识称为G-RNTI。
具体实现中，终端设备确定调度MAC层控制信息的无线网络临时标识后，若无线网络临时标识为多播业务专用的无线网络临时标识，则确定MAC层控制信息适用多播业务；若无线网络临时标识为单播业务专用的无线网络临时标识，则确定MAC层控制信息适用单播业务。
示例性的，接入网设备可以通过PDCCH调度PDSCH，利用RNTI加扰PDCCH，PDSCH承载了MAC sub PDU。MAC sub PDU包括subheader以及MAC CE。当MAC CE适用于单播业务，利用C-RNTI加扰PDCCH；当MAC CE适用于多播业务，利用G-RNTI加扰PDCCH。其中，C-RNTI为调度单播业务专用的无线网络临时标识，G-RNTI为调度多播业务专用的无线网络临时标识。
本申请实施例提供的方法中，通过逻辑信道标识指示MAC层控制信息的类型，通过调度MAC层控制信息的无线网络临时标识来指示终端业务。终端设备获取逻辑信道标识后可以识别出MAC层控制信息的类型，还可以根据调度MAC层控制信息的无线网络临时标识确定MAC层控制信息适用的类型，通过无线网络临时标识隐含指示终端业务，实现单播业务和多播业务的隔离配置，避免终端设备盲目进行DRX周期长度调整的同时，也降低了字段开销。
在本申请的另一实施例中，消息头可以包含指示payload中的MAC层控制信息的长度的字段，可以通过消息头是否包含该字段来指示终端业务。示例性的，确定MAC层控制信息对应的消息头是否包括第二信息；第二信息用于指示MAC层控制信息的长度；根据MAC层控制信息对应的消息头是否包括第二信息，确定MAC层控制信息适用的终端业务。
若MAC层控制信息对应的消息头包括第二信息，表明MAC层控制信息的长度是可变的，可以在MAC层控制信息指示该MAC层控制信息具体适用哪些多播业务，则可以确定该MAC层控制信息适用多播业务；若MAC层控制信息对应的消息头不包括第二信息，表明该MAC层控制信息的长度不可变，该MAC层控制信息适用单播业务。
示例性的，参考图7，消息头包括预留字段R、字段F、LCID以及字段L。其中，预留字段R、字段F、LCID占用8个比特，字段L占用8个比特。字段F用于指示消息头是否携带字段L，字段L为本申请实施例所述的第二信息，用于指示MAC层控制信息的长度。
例如，字段F为“1”表征消息头携带字段L，字段F为“0”表征消息头未携带字段L。当消息头中包括字段L，终端设备确定消息头对应的MAC层控制信息适用于多播业务，当消息头中不包括字段L，终端设备确定消息头对应的MAC层控制信息适用于单播业务。
一种可能的实现方式中，终端设备可以基于字段F确定消息头中是否包括字段L，即通过消息头中的字段F判断消息头中是否包括上述第二信息。
本申请实施例提供的方法中，通过逻辑信道标识指示MAC层控制信息的类型，通过“消息头中是否包含指示MAC CE长度的字段”这一方式来指示终端业务。终端设备获取逻辑信道标识后可以识别出MAC层控制信息的类型，还可以根据“消息头中是否包含指示MAC CE长度的字段”确定MAC层控制信息适用的类型，通过这种方式隐含指示终端业务，实现单播业务和多播业务的隔离配置，避免终端设备盲目进行DRX周期长度调整的同时，也降低了字段开销。
在本申请的另一实施例中，若消息头中包含指示MAC CE长度的字段，表明MAC层控制信息长度可变，MAC层控制信息可以指示MAC层控制信息具体适用的多播业务。示例性的，若MAC层控制信息对应的消息头包括第二信息，则MAC层控制信息包括第三信息，第三信息用于指示对一个或多个多播业务的接收进行DRX周期长度调整。
终端设备根据“消息头中是否包含第二信息”确定MAC层控制信息适用于多播业务，还可以根据MAC层控制信息中的第三信息，确定MAC层控制信息具体适用于哪些多播业务。例如，确定第三信息指示的一个或多个多播业务为MAC层控制信息适用的终端业务。
本申请实施例中，第三信息的实现包括以下三种：
第一、第三信息包括无线网络标识，通过无线网络临时标识指示MAC层控制信息适用的多播业务。
具体实现中，第三信息包括的一个或多个无线网络临时标识，终端设备可以根据第三信息包括的一个或多个无线网络临时标识，确定一个或多个多播业务；进一步还可以确定一个或多个多播业务为MAC层控制信息适用的终端业务。
其中，上述一个或多个无线网络临时标识(RNTI)与多播业务一一对应，RNTI可以是网络侧调度多播业务专用的无线网络临时标识G-RNTI。RNTI与多播业务的对应关系可以由网络侧预先配置。
示例性的，第三信息包括图8所示的RNTI列表。RNTI列表包括N个RNTI，分别为RNTI 1～RNTI n。其中，RNTI 1用于指示多播业务1、RNTI 2用于指示多播业务2……RNTI n用于指示多播业务n。终端设备可以根据MAC层控制信息中的RNTI列表确定MAC层控制信息适用的n个多播业务，终端设备可以根据该MAC层控制信息对这n个多播业务的接收进行DRX周期长度调整。
第二、第三信息包括索引号(index)，通过索引号指示MAC层控制信息适用的多播业务。
具体实现中，第三信息包括一个或多个索引号，该索引号可以是无线网络临时标识的索引号。终端设备可以根据第三信息包括的一个或多个索引号，确定一个或多个多播业务，确定上述一个或多个多播业务为MAC层控制信息适用的终端业务。
其中，上述一个或多个索引号与多播业务一一对应，索引号与多播业务的对应关系可以由网络侧预先配置。
一种可能的实现方式中，无线网络标识与多播业务存在对应关系，终端设备可以确定与上述一个或多个索引号关联的一个或多个无线网络临时标识，进一步根据无线网络标识与多播业务之间的对应关系，确定MAC层控制信息适用的多播业务。
示例性的，第三信息包括图9所示的index列表。index列表包括N个index，分别为index 1～index n。其中，index 1用于指示多播业务1、index 2用于指示多播业务2……index n用于指示多播业务n。终端设备可以根据MAC层控制信息中的index列表确定MAC层控制信息适用的n个多播业务，终端设备可以根据该MAC层控制信息对这n个多播业务的接收进行DRX周期长度调整。
第三、第三信息包括bitmap，通过bitmap指示MAC层控制信息适用的多播业务。
具体实现中，第三信息包括bitmap，bitmap的长度为N比特，N比特与N个多播业务一一对应。终端设备可以遍历N比特中的每一比特，根据比特的取值确定该比特对应的多播业务是否为MAC层控 制信息适用的多播业务。具体地，若该比特的取值为预设的有效值，则确定该比特对应的多播业务为MAC层控制信息适用的多播业务。
另一种实现方式中，N比特与N个索引号一一对应，索引号为无线网络临时标识的索引号，无线网络临时标识与多播业务存在对应关系。终端设备遍历N比特种的每一比特，若该比特的取值为有效值，则确定该比特对应的第一索引号，根据第一索引号确定第一无线网络临时标识，确定第一无线网络临时标识对应的多播业务为MAC层控制信息适用的多播业务。
另一种实现方式中，N比特与N个无线网络临时标识一一对应，终端设备遍历N比特种的每一比特，若该比特的取值为有效值，则确定该比特对应的第一无线网络临时标识，确定第一无线网络临时标识对应的多播业务为MAC层控制信息适用的多播业务。
示例性的，第三信息包括图10所示的bitmap。Bitmap包括N个比特，分别为M 1～M x。其中，M 1用于指示多播业务1、M 2用于指示多播业务2……M x用于指示多播业务x。终端设备可以根据MAC层控制信息中的N个比特确定MAC层控制信息适用的x个多播业务，终端设备可以根据该MAC层控制信息对这x个多播业务的接收进行DRX周期长度调整。
需要说明的是，N比特满足以下映射关系中的任意一种：N比特按照比特位从高到低的顺序依次对应N个多播业务、N比特按照比特位从低到高的顺序依次对应N个多播业务、N比特按照比特位从高到低的顺序依次对应N个从大到小排列的无线网络临时标识、N比特按照比特位从低到高的顺序依次对应N个从小到大排列的无线网络临时标识、N比特按照比特位从高到低的顺序依次对应N个从大到小排列的索引号以及N比特按照比特位从低到高的顺序依次对应N个从小到大排列的索引号。
本申请实施例对N个比特与多播业务的映射关系、N个比特与索引号的映射关系以及N个比特与无线网络临时标识的映射关系不作限制，任何通过N个比特指示MAC层控制信息具体适用的多播业务的方案均属于本申请实施例的保护范围。
在一种可能的实现方式中，上述三种实现方式中涉及的无线网络临时标识为多播业务专用的无线网络临时标识，即前文所述的G-RNTI。
上述第三信息的三种实现方式中，第三种实现方式的字段开销最低，通过较少的比特数量就可以实现具体多播业务的指示。
本申请实施例还提供一种DRX周期长度调整方法，适用于接入网设备，如图11所示，该方法包括以下步骤：
1101、接入网设备生成介质访问控制MAC层控制信息；
其中，MAC层控制信息可以是与DRX相关的MAC层控制信息，例如，可以是DRX command MAC CE或者long DRX command MAC CE。
接入网设备可以生成MAC层的PDU，该PDU包括消息头(subheader)和载荷(payload)。Subheader中包含逻辑信道标识，payload中包含MAC层控制信息，Subheader中的逻辑信道标识可以指示payload中包含的MAC层控制信息的类型。例如，逻辑信道标识可以指示payload中包含的是DRX command MAC CE还是long DRX command MAC CE。其中，逻辑信道标识可以是logic channel Identity document，简称LCID。
1102、接入网设备向终端设备发送MAC层控制信息，MAC层控制信息用于对MAC层控制信息适用的终端业务的接收进行非连续接收DRX周期长度调整；终端业务包括多播业务或单播业务。
具体实现中，接入网设备发送MAC sub PDU，MAC sub PDU包括MAC层控制信息。通过MAC层控制信息指示终端设备在进行DRX周期长度调整时区分业务类型，而不是盲目进行DRX周期长度调整，针对多播业务和单播业务的DRX周期长度调整进行隔离配置。
其中，多播业务可以包括组播和广播，单播业务可以是终端设备与接入网设备之间的点对点通信业务。
具体实现中，通过MAC层控制信息中携带的内容来指示MAC层控制信息适用的是多播业务还是单播业务，或者，可以根据MAC层控制信息对应的消息头中携带的内容指示MAC层控制信息适用的是多播业务还是单播业务，也可以根据上述消息头的接收资源来指示MAC层控制信息适用的是多播业务还是单播业务。其中，MAC层控制信息对应的消息头即承载该MAC层控制信息的payload对应的subheader。
一种可能的实现方式中，MAC层控制信息中携带的内容可以是MAC层控制信息中指定字段，例如，预留字段、复用已有字段等。消息头中携带的内容可以是消息头中指定字段，例如，预留字段、复用已有字段等。消息头的接收资源可以是承载该消息头的物理下行数据信道(physical downlink shared channel，PDSCH)，或者，也可以是PDSCH的加扰标识。其中，加扰标识可以是无线网络临时标识 (radio network temporary identifier，RNTI)。
需要说明的是，MAC层控制信息可以是DRX command MAC CE或者long DRX command MAC CE。其中，若MAC层控制信息为DRX command MAC CE，用于指示终端设备将该DRX command MAC CE适用的终端业务的DRX切换为该DRX command MAC CE。若MAC层控制信息为long DRX command MAC CE，用于指示终端设备将该long DRX command MAC CE适用的终端业务的DRX切换为该long DRX command MAC CE。
本申请实施例提供的方法中，接入网设备可以通过MAC层控制信息的方式指示终端设备在接收MAC层控制信息后，对MAC层控制信息适用的终端业务进行DRX周期长度调整。从而有区别性地对多播业务或单播业务的接收执行DRX周期长度切换操作，可以实现对多播业务和单播业务的隔离配置，避免终端设备盲目进行DRX周期长度切换，保证DRX周期长度切换与业务类型的准确匹配。
在本申请的另一实施例中，MAC层控制信息对应的消息头包括逻辑信息标识，逻辑信道标识用于MAC层控制信息的类型。其中，MAC层控制信息的类型包括：DRX相关的MAC CE、DRX command MAC CE或者long DRX command MAC CE。
在本申请的另一实施例中，逻辑信道标识还用于指示MAC层控制信息适用的终端业务。单播业务对应的逻辑信道标识与多播业务对应的逻辑信道标识不同。也就是说，为了区分单播业务、多播业务，给单播业务对应的MAC层控制信息、多播业务对应的MAC层控制信息定义了不同的逻辑信道标识。接入网设备可以通过消息头中的逻辑信道标识指示payload中的MAC层控制信息适用的是单播业务还是多播业务。
在本申请的另一实施例中，MAC层控制信息对应的消息头中携带指示终端业务的字段，终端设备可以根据消息头确定MAC层控制信息适用的是多播业务还是单播业务。示例性的，MAC层控制信息对应的消息头包括第一信息；第一信息用于指示MAC层控制信息适用于单播业务，或MAC层控制信息适用于多播业务。
在本申请的另一实施例中，可以通过调度MAC层控制信息的无线网络临时标识来指示终端业务。示例性的，MAC层控制信息承载于下行数据信道，下行数据信道的无线网络临时标识用于指示MAC层控制信息适用的终端业务。
具体实现中，下行数据信道的无线网络临时标识为多播业务专用的无线网络临时标识或单播业务专用的无线网络临时标识；其中，多播业务专用的无线网络临时标识用于指示MAC层控制信息适用多播业务，单播业务专用的无线网络临时标识用于指示MAC层控制信息适用单播业务。
也就是说，若调度MAC层控制信息的无线网络临时标识为多播业务专用的无线网络临时标识，则MAC层控制信息适用于多播业务；若调度MAC层控制信息的无线网络临时标识为单播业务专用的无线网络临时标识，则MAC层控制信息适用于单播业务。
例如，接入网设备可以通过PDCCH调度PDSCH，利用RNTI加扰PDCCH，PDSCH承载了MAC sub PDU。MAC sub PDU包括subheader以及MAC CE。当MAC CE适用于单播业务，利用C-RNTI加扰PDCCH；当MAC CE适用于多播业务，利用G-RNTI加扰PDCCH。其中，C-RNTI为调度单播业务专用的无线网络临时标识，G-RNTI为调度多播业务专用的无线网络临时标识
在本申请的另一实施例中，消息头可以包含指示payload中的MAC层控制信息的长度的字段，可以通过消息头是否包含该字段来指示终端业务。示例性的，若MAC层控制信息对应的消息头包括第二信息，表征MAC层控制信息适用多播业务；若MAC层控制信息对应的消息头不包括第二信息，表征MAC层控制信息适用单播业务；其中，第二信息用于指示MAC层控制信息的长度。
在本申请的另一实施例中，若MAC层控制信息对应的消息头包括第二信息，MAC层控制信息还包括第三信息，第三信息用于指示对一个或多个多播业务的接收进行DRX周期长度调整。
一种可能的实现方式中，第三信息包括一个或多个无线网络临时标识，MAC层控制信息适用于一个或多个无线网络临时标识对应的一个或多个多播业务。
另一种可能的实现方式中，第三信息包括一个或多个索引号，MAC层控制信息适用于一个或多个索引号对应的一个或多个多播业务，或，MAC层控制信息适用于一个或多个索引号关联的一个或多个无线网络临时标识对应的多播业务。
需要说明的是，上述一个或多个索引号与多播业务一一对应，或者，一个或多个索引号关联的一个或多个无线网络临时标识与多播业务一一对应。
在本申请实施例中，第三信息还可以为N比特，N比特中每一比特的取值用于指示比特对应的多播业务是否为MAC层控制信息适用的多播业务。
需要说明的是，N比特满足以下映射关系中的任意一种：N比特按照比特位从高到低的顺序依次对应N个多播业务、N比特按照比特位从低到高的顺序依次对应N个多播业务、N比特按照比特位从高到低的顺序依次对应N个从大到小排列的无线网络临时标识、N比特按照比特位从低到高的顺序依次对应N个从小到大排列的无线网络临时标识、N比特按照比特位从高到低的顺序依次对应N个从大到小排列的索引号以及N比特按照比特位从低到高的顺序依次对应N个从小到大排列的索引号。
可选的，上述第三信息的各种实现方式中涉及的无线网络临时标识为多播业务专用的无线网络临时标识，即前文所述的G-RNTI。
本申请实施例还提供一种DRX周期长度调整方法，适用于图2所示系统中的终端设备和接入网设备。如图12所示，该方法包括以下步骤：
1201、接入网设备向终端设备发送MAC层控制信息；
1202、终端设备确定MAC层控制信息适用的终端业务；
具体地，根据MAC层控制信息中的字段确定MAC层控制信息适用的终端业务，或者，根据MAC层控制信息对应的消息头中的字段确定MAC层控制信息适用的终端业务，或者，根据调度MAC层控制信息的无线网络临时标识确定MAC层控制信息适用的终端业务。
1203、终端设备根据MAC层控制信息对MAC层控制信息适用的终端业务的接收进行DRX周期长度调整，基于调整后的DRX周期长度进行下行业务的接收。
