Description

一种通信方法和装置
本申请要求于2020年05月29日提交国家知识产权局、申请号为202010478665.9、申请名称为“一种通信方法和装置”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
本申请涉及通信领域，尤其涉及一种通信方法和装置。
背景技术
大规模机器类型通信(massive machine type communications，mMTC)是第五代(5 th generation，5G)移动通信系统的重要应用场景之一，主要面向基于蜂窝网络的各类物联网(internet of things，IoT)业务。mMTC应用场景的主要特征是大规模海量物联网终端的连接需求，例如每平方公里可达到100万连接。此外，mMTC应用场景还具有低数据量(例如，数十个字节的小数据包传输)、低功耗(例如，物联网终端电池寿命可达10年)、深覆盖(支持各类弱覆盖场景，如地下车库、电梯井等)和低复杂度(降低终端和网络成本)等特征。
在mMTC场景下，终端设备可直接通过长期演进(long term evolution，LTE)或5G等无线接入技术接入到网络，也可以先连接到一个中继(Relay)节点(例如可以是手机、传感器等)，再通过中继节点接入到网络。通过中继节点接入网络的优势之一是省电，由于中继节点通常距离终端设备较近，通过近距离通信可以降低终端设备功耗；优势之二是覆盖扩展，当终端设备所处区域网络覆盖不好或无网络覆盖时，可将相邻设备作为中继节点接入网络。
但是，当终端设备通过中继节点连接到网络后，终端设备与中继节点之间需要长期保持侧行链路(Sidelink)连接，通信能耗大。

具体实施方式
为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
DRX周期(DRX cycle)：如图1所示，DRX cycle可以由“启动持续时间”和“DRX机会”组成。其中，启动持续时间可以称为On Duration，DRX机会可以称为Opportunity for DRX。在On Duration起始时刻(或者DRX Cycle起始时刻)，可以启动DRX开启持续时间定时器(drx-onDurationTimer，也可以称为onDurationTimer)，drx-onDurationTimer的时长为On Duration的时长，终端设备可以在drx-onDurationTimer运行期间内处于唤醒状态，即监测物理下行控制信道(physical downlink control channel，PDCCH)。当drx-onDurationTimer超时则表示“on Duration”时间结束，此时终端设备可以进入“Opportunity for DRX”时间，在“Opportunity for DRX”期间内，终端设备处于休眠期(睡眠状态)，不接收PDCCH以减少功耗。但是，若终端设备在drx-onDurationTimer运行期间内接收到调度初传(new transmission)的PDCCH，由于终端设备很可能在接下来的时间内继续被基站调度，因此终端设备可以启动(或重启)非激活定时器(drx-InactivityTimer)。终端设备可以在drx-InactivityTimer运行期间继续监测PDCCH直到drx-InactivityTimer超时。总的来说，在drx-onDurationTimer和/或drx-InactivityTimer运行期间，可以认为终端设备处于激活期(active time)，即需要监测PDCCH。也就是说，当DRX周期被配置时，UE可以在激活期(Active time)内醒来监测PDCCH；否则，UE不需要监测PDCCH，即UE可以休眠，UE在“休眠期”的功耗低于在DRX“激活期”的功耗。
目前，第三代合作伙伴计划(3rd generation partnership project，3GPP)协议定义了终端设备在初始注册或位置移动更新注册过程中通过注册请求信息与核心网进行DRX协商 的主要方案与流程：1、在初始注册或者移动性注册更新过程中，终端设备可以将其请求的DRX参数携带在注册请求信息中通过非接入层(non access stratum，NAS)信令告知AMF。2、AMF可以根据终端设备请求的DRX参数与运营商策略进行DRX参数决策，通常可以直接接受终端设备请求的DRX参数。3、AMF可以在注册接受信息中将决策的DRX参数告知终端设备。
上述过程说明了终端设备如何进行独立的Uu DRX参数确定。当终端设备通过中继节点连接到网络后，终端设备与中继节点之间需要长期保持侧行链路(Sidelink)连接，通信能耗大。为了节约终端设备与中继节点的通信能耗，可以借鉴Uu DRX机制，在Sidelink通信中引入Sidelink DRX节能方案。
并且，当终端设备通过中继节点连接到网络后，即当终端设备(例如，Remote UE)选择中继节点(例如，Relay UE)之后，两UE之间会存在一定的绑定关系，再进行独立的Uu DRX参数确定将会带来丢失寻呼的后果。例如，当Remote UE不在覆盖范围内时，Remote UE需要通过Relay UE进行数据通信，而当Relay UE进入休眠态后，无法接收到网络侧对Remote UE的寻呼信息，从而造成Remote UE寻呼丢失，影响Remote UE的网络通信服务。
本申请实施例提供一种通信方法，可以基于第一终端设备(例如，Remote UE)与第二终端设备(例如，Relay UE)的Uu DRX参数进行Sidelink DRX参数配置。具体的，第一终端设备向接入和移动管理功能网元发送第一类型的DRX参数(Uu DRX参数)后，接入和移动管理功能网元可以根据第一类型的DRX参数确定第二类型的DRX参数(Sidelink DRX参数)并发送给第一终端设备。其中，第一类型的DRX参数用于第一终端设备与网络设备(接入网设备)之间的通信以及第二终端设备与网络设备之间的通信，第二类型的DRX参数用于第一终端设备与第二终端设备之间的通信。这样，第一终端设备与第二终端设备通信时，可以根据第二类型的DRX参数进入休眠态，从而可以降低第一终端设备和第二终端设备的通信能耗。
本申请实施例提供的通信方法和装置可以应用于5G移动通信系统。本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统。其中，通信系统可以是未来演进的公用陆地移动通信网络(public land mobile network，PLMN)网络、设备到设备(device to device，D2D)网络、机器到机器(machine to machine，M2M)网络、物联网(internet of things，IoT)网络或者其他网络，本申请不做限定。
如图2所示，本申请实施例所涉及的网络架构可以是第五代系统(5th generation system，5GS)，该5GS包括接入和移动管理功能(access and mobility management function，AMF)网元、会话管理功能(session management function，SMF)网元、用户面功能(user plane function，UPF)网元、统一数据管理(unified data management，UDM)网元、策略控制功能(policy control function，PCF)网元、鉴权服务器功能(authentication server function，AUSF)网元、网络开放功能(network exposure function，NEF)网元以及一些未示出的网元，如网络功能存储功能(network function repository function，NRF)网元等。上述5GS中的网元也可以称为5G核心网网元。
其中，AMF负责接入与移动性管理功能，其可以接收终端设备的非接入层(non-access stratum，NAS)信令(包括会话会话管理(session management，SM)信令)和接入网设备的 相关信令，完成用户的注册流程和SM信令的转发以及移动性管理。
SMF负责会话管理功能，完成与PDU会话相关的建立、释放、更新等流程。
PCF负责用户策略管理，既包括移动性相关策略，也包括PDU会话相关策略，如服务质量(quality of service，QoS)策略、计费策略等。

为了便于理解，以下结合附图对本申请实施例提供的通信方法进行具体介绍。
如图5所示，本申请实施例提供一种通信方法，包括：
501、第一终端设备向接入和移动管理功能网元发送第一信息。
第一信息包括第一类型的DRX参数，第一类型的DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信。其中，网络设备可以是指接入网设备。也就是说，第一类型的DRX参数适用于Uu口的通信，因此也可以将第一类型的DRX参数称为Uu DRX参数。第一类型的DRX参数可以表征第一终端设备与网络设备通信时的节能需求，以及第二终端设备与网络设备通信时的节能需求。第一类型的DRX参数可以包括DRX周期时长、DRX休眠期时长、DRX激活期时长或寻呼时间窗口中的至少一个。
在一种可能的设计中，第一类型的DRX参数包括第一终端设备的第一DRX参数和第二终端设备的第二DRX参数。其中，第一DRX参数用于第一终端设备与网络设备之间的通信，第一DRX参数可以是第一终端设备在初始注册、位置移动更新注册过程中通过注册请求信息与核心网设备(例如，AMF)协商(即通过一条或多条信令交互)得到的。第 二DRX参数用于第二终端设备与网络设备之间的通信，第二DRX参数可以是第二终端设备在初始注册、位置移动更新注册过程中通过注册请求信息与核心网设备协商得到的。
在本申请实施例中，第一终端设备与第二终端设备之间完成中继选择与发现流程后，可以通过侧行链路获取对方的DRX参数。例如，第一终端设备可以通过侧行链路向第二终端设备发送第一终端设备的第一DRX参数，以便第二终端设备获取第一终端设备的DRX参数(即第一DRX参数)。或者，第一终端设备可以接收第二终端设备通过侧行链路发送的第二终端设备的第二DRX参数，即第一终端设备可以获取第二终端设备的DRX参数(即第二DRX参数)。而后，在第一终端设备或第二终端设备的最近一次注册过程中(初始注册或者移动性更新注册)，第一终端设备或第二终端设备可以将两者的DRX参数(第一DRX参数和第二DRX参数)携带在注册请求信息中通过NAS信令发送给AMF。可选的，注册请求信息中还可以携带第一终端设备和/或第二终端设备的身份标识信息。
其中，第一终端设备可以为远程终端设备(例如，Remote UE)或中继终端设备(例如，Relay UE)。第二终端设备也可以为远程终端设备或中继终端设备。当第一终端设备为远程终端设备时，第二终端设备为中继终端设备；当第一终端设备为中继终端设备时，第二终端设备为远程终端设备。
可选的，若第一终端设备为Remote UE且不在网络覆盖范围内，则可以由第二终端设备(即Relay UE)负责信息上报(即将双方的DRX参数发送给AMF)。或者，若第二终端设备为Remote UE且不在网络覆盖范围内，则可以由第一终端设备(即Relay UE)负责信息上报。
在另一种可能的设计中，第一类型的DRX参数包括第三DRX参数，第三DRX参数是根据第一终端设备的第一DRX参数和第二终端设备的第二DRX参数确定的。示例性的，第一终端设备可以从第二终端设备接收第二终端设备的第二DRX参数，并根据第二终端设备的第二DRX参数和第一终端设备的第一DRX参数确定第三DRX参数。
在一些实施例中，第一终端设备可以在中继选择与发现过程中从第二终端设备接收第二终端设备的第二DRX参数，并根据第二终端设备的第二DRX参数和第一终端设备的第一DRX参数确定第三DRX参数。第三DRX参数可以为第一DRX参数或第二DRX参数，即第三DRX参数可以与第一DRX参数或第二DRX参数相同。其中，中继选择与发现过程可以包括两种模式(模式A和模式B)。下面以第一终端设备为Remote UE，第二终端设备为Relay UE为例，对模式A的中继发现与选择流程进行说明。
步骤1：Relay UE广播中继信息，该中继信息包括该Relay UE的DRX参数(第二DRX参数)。
步骤2：由于中继信息是广播的，可以有多个终端设备接收到该中继信息，该多个终端设备中需要进行中继且接受该中继信息的终端设备是Remote UE。具体的，Remote UE接收到Relay UE广播的中继信息后，可以将Relay UE的DRX参数(第二DRX参数)与自身的DRX参数(第一DRX参数)进行比较，若确定Relay UE的DRX参数可用/可接受(例如，确定两者的DRX参数相近，比如Relay UE的DRX参数用于指示DRX周期时长为10s，DRX休眠期时长为5s；自身的DRX参数用于指示DRX周期时长为10s，DRX休眠期时长为6s)，则确定第三DRX参数为第二DRX参数，同时Remote UE可以与Relay UE进行侧行链路通信。
下面以第一终端设备为Relay UE，第二终端设备为Remote UE为例，对模式B的中继发现与选择过程进行说明。
步骤1：Remote UE广播中继请求信息(solicitation信息)，该中继请求信息包括Remote UE的DRX参数(第二DRX参数)；
步骤2：由于中继请求信息是广播的，可以有多个终端设备接收到该中继请求信息，该多个终端设备中能够进行中继且接受该中继请求信息的终端设备可以是Relay UE。Relay UE接收到Remote UE广播的中继请求信息后，可以将Remote UE的DRX参数(第二DRX参数)与自身的DRX参数(第一DRX参数)进行比较，若确定Remote UE的DRX参数可用/可接受，则确定第三DRX参数为第二DRX参数，并可以向Remote UE回复响应信息。
在一种可能的情况中，能够进行中继且接受Remote UE广播的中继请求信息的终端设备可能有两个或两个以上，此时，该两个或两个以上的终端设备都可以向Remote UE回复响应信息，并可以将自身的DRX参数携带在响应信息中告知给Remote UE。Remote UE可以根据该两个或两个以上的终端设备的DRX参数和自身的DRX参数(第二DRX参数)，确定是否要选择相应的终端设备作为Relay UE。例如，Remote UE可以将与自身的DRX参数最为接近的一个终端设备作为Relay UE。由于Relay UE是能够进行中继且接受Remote UE广播的DRX参数的终端设备，且Remote UE可以接受Relay UE的DRX参数，因此第二终端设备可以确定第三DRX参数为Relay的DRX参数(第一DRX参数)或自身的DRX参数(第二DRX参数)。
在另一些实施例中，第一终端设备可以在完成中继选择与发现过程后，通过侧行链路从第二终端设备接收第二终端设备的第二DRX参数，并根据第二终端设备的第二DRX参数和第一终端设备的第一DRX参数确定第三DRX参数。第三DRX参数可以为第一DRX参数或第二DRX参数或折中的DRX参数(即综合考虑第一DRX参数或第二DRX参数以及第一终端设备和第二终端设备的业务情况(业务特性、节能需求)和签约信息等确定的DRX参数)。
而后，在第一终端设备或第二终端设备的最近一次注册过程中(初始注册或移动性更新注册)，第一终端设备或第二终端设备可以将第三DRX参数携带在注册请求信息中通过NAS信令发送给AMF。可选的，注册请求信息中还可以携带第一终端设备和/或第二终端设备的身份标识信息。
另外，第一信息可以是指示信息，该指示信息包括第一终端设备和/或第二终端设备的身份标识信息，用于指示接入和移动管理功能网元获取第一DRX参数和第二DRX参数，第一DRX参数和第二DRX参数可以分别存在于第一终端设备的上下文中和第二终端设备的上下文中，第一终端设备的上下文和第二终端设备的上下文可以存储在接入和移动管理功能网元上。
502、接入和移动管理功能网元从第一终端设备接收第一信息。
第一信息可以参考步骤501中的相关描述，在此不做赘述。
接入和移动管理功能网元接收到第一信息后，可以根据第一信息确定第二信息，第二信息包括第二类型的DRX参数，即接入和移动管理功能网元可以根据第一类型的DRX参数确定第二类型的DRX参数。其中，第二类型的DRX参数用于第一终端设备与第二终端 设备之间的通信，即第二类型的DRX参数适用于Sidelink的通信，因此第二类型的DRX参数也可以称为Sidelink DRX参数。第二类型的DRX参数可以表征第一终端设备与第二终端设备通信时的节能需求。第二类型的DRX参数包括DRX周期时长、DRX休眠期时长、DRX激活期时长或寻呼时间窗口中的至少一个。
可选的，接入和移动管理功能网元在根据第一类型的DRX参数确定第二类型的DRX参数时，还可以结合(或者考虑)第一终端设备以及第二终端设备的业务情况和签约信息等。第二类型的DRX参数可以与第一类型的DRX参数相近或一致。
当第一类型的DRX参数包括第一DRX参数和第二DRX参数时，接入和移动管理功能网元还可以根据第一DRX参数和第二DRX参数对第一终端设备和第二终端设备的Uu DRX参数进行决策(determine)，即重新确定第一终端设备和第二终端设备的Uu DRX参数，并将重新确定的Uu DRX参数携带在第二信息中发送给第一终端设备。
在一种可能的实现方式中，如果第一终端设备和第二终端设备都在网络覆盖范围内且无法联合配置两者的DRX参数(例如，两者的DRX参数差异过大，比如第一终端设备的第一DRX参数指示DRX周期时长为10s，DRX休眠期时长为5s；第二终端设备的第二DRX参数指示DRX周期时长为5s，DRX休眠期时长为1s)，接入和移动管理功能网元可以为第一终端设备和第二终端设备分别确定第四DRX参数和第五DRX参数，并将第四DRX参数和第五DRX参数携带在第二信息中发送给第一终端设备。其中，第四DRX参数用于第一终端设备与网络设备之间的通信；第五DRX参数用于第二终端设备与网络设备之间的通信。
接入和移动管理功能网元可以根据第一DRX参数和第二DRX参数确定第四DRX参数和第五DRX参数。可选的，接入和移动管理功能网元在确定第四DRX参数和第五DRX参数时，还可以结合(或者考虑)第一终端设备和第二终端设备的业务情况和签约信息等。
在一种可能的实现方式中，第四DRX参数与第五DRX参数指示的DRX周期时长可以相同，但第四DRX参数指示的DRX激活期与第五DRX参数指示的DRX激活期不相互重叠(例如，交替出现)，这样，第一终端设备和第二终端设备可以在不同时间进入激活态。无论哪个终端设备进入激活态，都可以同时监听网络侧对两个终端设备(第一终端设备和第二终端设备)的Uu寻呼信息。也就是说，第一终端设备进入激活态后，不仅可以监听网络侧对第一终端设备的Uu寻呼信息，还可以监听网络侧对第二终端设备的Uu寻呼信息；第二终端设备进入激活态后，不仅可以监听网络侧对第二终端设备的Uu寻呼信息，还可以监听网络侧对第一终端设备的Uu寻呼信息。这样，可以保持两个终端设备的寻呼信息的可达性，避免丢失寻呼信息，并且，两个终端设备的DRX参数做到了协同配置(交替进入激活态)，提升了节能效果。
示例性的，如图6a中的(a)所示，假设第一终端设备的第一DRX参数指示的DRX周期时长为10s，激活期时长为1s；如图6a中的(b)所示，第二终端设备的第二DRX参数指示的DRX周期时长为20s，激活期时长为2s；基于上述参数，如图6a中的(c)和(d)所示，可以设置第四DRX参数与第五DRX参数指示的DRX周期时长都为30s，如图6a中的(c)所示，第四DRX参数指示的激活期时长为1s，如图6a中的(d)所示，第五DRX参数指示的激活期时长为2s，且第四DRX参数指示的DRX激活期与第五DRX参数指示的DRX激活期不相互重叠。这样，增长了第一终端设备和第二终端设备的寻呼周期 时长，可以降低第一终端设备与第二终端设备的功耗，并且不会减少第一终端设备和第二终端设备被网络侧寻呼的时长(这是由于无论哪个终端设备进入激活态，都可以同时监听网络侧对两个终端设备(第一终端设备和第二终端设备)的Uu寻呼信息，对于第一终端设备和第二终端设备来说，在30s内仍有3s可获取网络侧的寻呼信息)，可以确保第一终端设备与第二终端设备的下行业务需求。
又例如，如图6b所示，假设第四DRX参数与第五DRX参数指示的DRX周期时长为10s，第四DRX参数指示的DRX激活期时长可以为5s且为DRX周期的前5s，第五DRX参数指示的DRX激活期时长可以为5s且为DRX周期的后5s。这样，第一终端设备可以在DRX周期的前5s进入激活态，第二终端设备可以在DRX周期的后5s进入激活态，即第一终端设备和第二终端设备可以交替进入激活态。这样，可以保持两个终端设备的寻呼信息的可达性，不会丢失寻呼信息，并且，两个终端设备的DRX参数做到了协同配置(交替进入激活态)，提升了节能效果。
可选的，第二信息还可以包括指示信息，指示信息用于指示第一终端设备是否根据第四DRX参数进行寻呼监听。以第一终端设备为Remote UE，第二终端设备为Relay UE为例，当Remote UE的Uu DRX周期(即第四DRX参数指示的DRX周期)较大而Relay UE的Uu DRX周期(即第五DRX参数指示的DRX周期)较小，此时指示信息可以指示Remote UE不根据第四DRX参数进行寻呼监听，由Relay UE负责监听网络设备对两者的寻呼信息，即由Relay UE代替Remote UE监听寻呼信息。这样，当Remote UE处于网络覆盖范围外时，可以通过Relay UE获取网络设备对自身的寻呼信息，避免造成Remote UE的寻呼丢失。
在另一种可能的实现方式中，如果可以联合配置两者的DRX参数(例如，两者的DRX参数差异不大，比如第一终端设备的第一DRX参数用于指示DRX周期时长为10s，DRX休眠期时长为5s；第二终端设备的第二DRX参数用于指示DRX周期时长为12s，DRX休眠期时长为6s)，接入和移动管理功能网元可以为第一终端设备和第二终端设备确定一个共同的DRX参数，即第六DRX参数。第六DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信。第六DRX参数可以是根据第一DRX参数和第二DRX参数确定的。
在一种可能的实现方式中，当Remote UE不在覆盖范围内时，可以通过Relay UE与网络侧进行通信，即由Relay UE代替Remote UE接收网络侧对Remote UE的寻呼信息，如果Relay UE的Uu DRX过长，网络侧可能无法及时寻呼到Relay UE，导致难以保障Remote UE的业务需求。因此，可以设置第六DRX参数为第一DRX参数和第二DRX参数中周期较小(短)的一个。这样，可以避免Remote UE的寻呼丢失，能够保障Remote UE的业务需求。
503、接入和移动管理功能网元向第一终端设备发送第二信息。
示例性的，接入和移动管理功能网元可以向第一终端设备发送注册接受信息，注册接受信息中包含第二信息，第二信息可以参考步骤502的相关描述，在此不做赘述。
504、第一终端设备从接入和移动管理功能网元接收第二信息。
示例性的，第一终端设备可以接收接入和移动管理功能网元发送的注册接受信息，注册接受信息中包含第二信息，第二信息可以参考步骤502的相关描述，在此不做赘述。
505、第一终端设备通过侧行链路向第二终端设备发送第二类型的DRX参数。
第一终端设备与第二终端设备通信时，可以根据第二类型的DRX参数进入休眠态，不需要一直保持Sidelink通信接口，从而可以降低通信能耗。
第一终端设备与第二终端设备还可以通过侧行链路交换对方的无线网络临时标识(radio network temporary identity，RNTI)，RNTI例如可以是寻呼RNTI(paging-RNTI，P-RNTI)或者是临时移动用户识别码(temporary mobile subscriber identity,TMSI)，例如S-TMSI，以便进行后续的下行寻呼。当第一终端设备进入激活态时，不仅可以监听网络侧对自身的寻呼，而且可以根据第二终端设备的RNTI为第二终端设备监听寻呼信息(即确定网络侧是否发送了携带第二终端设备的RNTI的寻呼消息)，避免第二终端设备的寻呼丢失，能够保障第二终端设备的业务需求。或者，当第二终端设备进入激活态时，不仅可以监听网络侧对自身的寻呼，而且可以根据第一终端设备的RNTI为第一终端设备监听寻呼信息，避免第一终端设备的寻呼丢失，能够保障第一终端设备的业务需求。同时，第一终端设备与第二终端设备还可以通过侧行链路完成定时器(例如，drx-onDurationTimer)的同步。
在一种可能的实现方式中，第一终端设备还可以通过侧行链路向第二终端设备发送第四DRX参数与第五DRX参数。若第四DRX参数与第五DRX参数指示的DRX周期时长相同，但第四DRX参数指示的DRX激活期与第五DRX参数指示的DRX激活期不相互重叠，则第一终端设备和第二终端设备可以在不同时间进入激活态。无论哪个终端设备进入激活态，都可以同时监听网络侧对两个终端设备(第一终端设备和第二终端设备)的Uu寻呼信息。示例性的，如果第一终端设备在第四DRX参数指示的激活态期间监听到网络侧对第二终端设备的寻呼信息，可以通过服务请求(service request)流程获取对应的下行数据(MT data)，并可以根据第二类型的DRX参数，在对应的Sidelink激活态期间通过Sidelink通信寻呼第二终端设备；第二终端设备接收到第一终端设备的Sidelink寻呼后，可以与第一终端设备建立通信链路并接收第一终端设备从网络侧获取的下行数据。类似的，如果第二终端设备在第五DRX参数指示的激活态期间监听到网络侧对第一终端设备的寻呼信息，可以通过service request流程获取对应的下行数据，并可以根据第二类型的DRX参数在对应的Sidelink激活态期间通过Sidelink通信寻呼第一终端设备；Relay接收到第二终端设备的Sidelink寻呼后，可以与第二终端设备建立通信链路并接收第二终端设备从网络侧获取的下行数据。
基于本申请提供的方法，第一终端设备可以向接入和移动管理功能网元发送第一类型的DRX参数后，接入和移动管理功能网元可以根据第一类型的DRX参数确定第二类型的DRX参数并发送给第一终端设备。其中，第一类型的DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信，第二类型的DRX参数用于第一终端设备与第二终端设备之间的通信。这样，第一终端设备与第二终端设备通信时，可以根据第二类型的DRX参数进入休眠态，从而可以降低通信能耗。
如图7所示，本申请实施例提供一种通信方法，包括：
701、第一终端设备与第二终端设备确定第一类型的DRX参数。
其中，第一终端设备可以为远程终端设备(例如，Remote UE)或中继终端设备(例如，Relay UE)。第二终端设备也可以为远程终端设备或中继终端设备。当第一终端设备为 远程终端设备时，第二终端设备为中继终端设备；当第一终端设备为中继终端设备时，第二终端设备为远程终端设备。
第一类型的DRX参数包括第三DRX参数，第三DRX参数可以是根据第一终端设备的第一DRX参数和第二终端设备的第二DRX参数确定的。示例性的，第一终端设备可以从第二终端设备接收第二终端设备的第二DRX参数，并根据第二终端设备的第二DRX参数和第一终端设备的第一DRX参数确定第三DRX参数。
在一些实施例中，第一终端设备可以在中继选择与发现过程中从第二终端设备接收第二终端设备的第二DRX参数，并根据第二终端设备的第二DRX参数和第一终端设备的第一DRX参数确定第三DRX参数。第三DRX参数可以为第一DRX参数或第二DRX参数，即第三DRX参数可以与第一DRX参数或第二DRX参数相同。其中，中继选择与发现过程可以包括两种模式(模式A和模式B)。具体过程可以参考步骤501的相关说明，在此不做赘述。
在另一些实施例中，第一终端设备可以在完成中继选择与发现过程后，通过侧行链路从第二终端设备接收第二终端设备的第二DRX参数，并根据第二终端设备的第二DRX参数和第一终端设备的第一DRX参数确定第三DRX参数。第三DRX参数可以为第一DRX参数或第二DRX参数或折中的DRX参数(即综合考虑第一DRX参数或第二DRX参数以及第一终端设备和第二终端设备的业务情况和签约信息等确定的DRX参数)。
可选的，第一终端设备与第二终端设备还可以重新确定第一终端设备和第二终端设备的Uu DRX参数，例如可以为第一终端设备和第二终端设备分别确定第四DRX参数和第五DRX参数。示例性的，第四DRX参数与第五DRX参数指示的DRX周期时长可以相同，但第四DRX参数指示的DRX激活期与第五DRX参数指示的DRX激活期可以不相互重叠，这样，第一终端设备和第二终端设备可以在不同时间进入激活态。无论哪个终端设备进入激活态，都可以同时监听网络侧对两个终端设备(第一终端设备和第二终端设备)的Uu寻呼信息。也就是说，第一终端设备进入激活态后，不仅可以监听网络侧对第一终端设备的Uu寻呼信息，还可以监听网络侧对第二终端设备的Uu寻呼信息；第二终端设备进入激活态后，不仅可以监听网络侧对第二终端设备的Uu寻呼信息，还可以监听网络侧对第一终端设备的Uu寻呼信息。这样，可以保持两个终端设备的寻呼信息的可达性，避免丢失寻呼信息，并且，两个终端设备的DRX参数做到了协同配置(交替进入激活态)，提升了节能效果。
702、第一终端设备与第二终端设备确定第二类型的DRX参数。
第一终端设备与第二终端设备可以根据第一类型的DRX参数确定第二类型的DRX参数，并且可以结合(或者考虑)第一终端设备以及第二终端设备的业务情况和签约信息等确定第二类型的DRX参数。第二类型的DRX参数可以与第一类型的DRX参数相近或一致。
基于本申请提供的方法，第一终端设备与第二终端设备可以根据第一类型的DRX参数确定第二类型的DRX参数。其中，第一类型的DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信，第二类型的DRX参数用于第一终端设备与第二终端设备之间的通信。这样，第一终端设备与第二终端设备通信时，可以根据第二类型的DRX参数进入休眠态，从而可以降低通信能耗。
如图8所示，本申请实施例提供一种通信方法，包括：
801、第一终端设备或接入和移动管理功能网元向接入网设备发送第一信息。
第一信息包括第一类型的DRX参数，第一类型的DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信。其中，网络设备可以是指接入网设备。也就是说，第一类型的DRX参数适用于Uu口的通信，因此也可以将第一类型的DRX参数称为Uu DRX参数。第一类型的DRX参数可以表征第一终端设备与网络设备通信时的节能需求，以及第二终端设备与网络设备通信时的节能需求。第一类型的DRX参数可以包括DRX周期时长、DRX休眠期时长、DRX激活期时长或寻呼时间窗口中的至少一个。
在一种可能的设计中，第一类型的DRX参数包括第一终端设备的第一DRX参数和第二终端设备的第二DRX参数。其中，第一DRX参数用于第一终端设备与网络设备之间的通信，第一DRX参数可以是第一终端设备在初始注册、位置移动更新注册过程中通过注册请求信息与核心网设备(例如，AMF)协商(即通过一条或多条信令交互)，并在寻呼过程中发送至接入网设备，由接入网设备确定的。第二DRX参数用于第二终端设备与网络设备之间的通信，第二DRX参数可以是第二终端设备在初始注册、位置移动更新注册过程中通过注册请求信息与核心网设备协商后，在寻呼过程中发送至接入网设备，由接入网设备确定的。
具体的，对于DRX参数，UE在注册过程中与AMF协商得到后，由AMF发往接入网设备侧，接入网设备根据其寻呼DRX配置与上述协商结果确定得到UE的第一DRX参数，其中寻呼DRX配置会在接入网设备的广播消息中，UE可以根据与AMF协商的DRX结果与广播信息中DRX参数自行确定第一DRX参数；若该DRX指的是扩展DRX参数，那么UE将会在注册过程中与AMF协商后，将结果发往接入网设备，由接入网设备自行进行确定该UE的第一DRX参数，并告知UE侧。
在本申请实施例中，第一终端设备与第二终端设备之间完成中继选择与发现流程后，可以通过侧行链路获取对方的DRX参数。具体参照前面501中的描述。
而后，在第一终端设备或第二终端设备的最近一次注册过程中(初始注册或移动性更新注册)，第一终端设备或第二终端设备可以将第三DRX参数携带在RRC(无线资源控制，Radio Resource Control)消息发送给RAN。可选的，注册请求信息中还可以携带第一终端设备和/或第二终端设备的身份标识信息。
另外，第一信息可以是指示信息，该指示信息包括第一终端设备和/或第二终端设备的身份标识信息，用于指示接入网设备根据身份标识获取第一DRX参数和第二DRX参数，第一DRX参数和第二DRX参数可以分别存在于第一终端设备的上下文中和第二终端设备的上下文中，第一终端设备的上下文和第二终端设备的上下文可以存储在接入网设备上。
802、接入网设备接收第一信息。
接入网设备可以从第一终端设备接收第一信息。或者，接入网设备可以从接入和移动管理功能网元接收第一信息。
第一信息可以参考步骤801中的相关描述，在此不做赘述。
接入网设备接收到第一信息后，可以根据第一信息确定第二信息，第二信息包括第二类型的DRX参数，即接入网设备可以根据第一类型的DRX参数确定第二类型的DRX参 数。其中，第二类型的DRX参数用于第一终端设备与第二终端设备之间的通信，即第二类型的DRX参数适用于Sidelink的通信，因此第二类型的DRX参数也可以称为Sidelink DRX参数。第二类型的DRX参数可以表征第一终端设备与第二终端设备通信时的节能需求。第二类型的DRX参数包括DRX周期时长、DRX休眠期时长、DRX激活期时长或寻呼时间窗口中的至少一个。
可选的，接入网设备在根据第一类型的DRX参数确定第二类型的DRX参数时，还可以结合(或者考虑)第一终端设备以及第二终端设备的业务情况等。第二类型的DRX参数可以与第一类型的DRX参数相近或一致。
当第一类型的DRX参数包括第一DRX参数和第二DRX参数时，接入网设备还可以根据第一DRX参数和第二DRX参数对第一终端设备和第二终端设备的Uu DRX参数进行决策(determine)，即重新确定第一终端设备和第二终端设备的Uu DRX参数，并将重新确定的Uu DRX参数携带在第二信息中发送给第一终端设备。
在一种可能的实现方式中，如果第一终端设备和第二终端设备都在网络覆盖范围内且无法联合配置两者的DRX参数(例如，两者的DRX参数差异过大，比如第一终端设备的第一DRX参数指示DRX周期时长为10s，DRX休眠期时长为5s；第二终端设备的第二DRX参数指示DRX周期时长为5s，DRX休眠期时长为1s)，接入网设备可以为第一终端设备和第二终端设备分别确定第四DRX参数和第五DRX参数，并将第四DRX参数和第五DRX参数携带在第二信息中发送给第一终端设备。其中，第四DRX参数用于第一终端设备与网络设备之间的通信；第五DRX参数用于第二终端设备与网络设备之间的通信。
接入网设备可以根据第一DRX参数和第二DRX参数确定第四DRX参数和第五DRX参数。可选的，接入网设备在确定第四DRX参数和第五DRX参数时，还可以结合(或者考虑)第一终端设备和第二终端设备的业务情况等。
在一种可能的实现方式中，第四DRX参数与第五DRX参数指示的DRX周期时长可以相同，但第四DRX参数指示的DRX激活期与第五DRX参数指示的DRX激活期不相互重叠(例如，交替出现)，这样，第一终端设备和第二终端设备可以在不同时间进入激活态。无论哪个终端设备进入激活态，都可以同时监听网络侧对两个终端设备(第一终端设备和第二终端设备)的Uu寻呼信息。也就是说，第一终端设备进入激活态后，不仅可以监听网络侧对第一终端设备的Uu寻呼信息，还可以监听网络侧对第二终端设备的Uu寻呼信息；第二终端设备进入激活态后，不仅可以监听网络侧对第二终端设备的Uu寻呼信息，还可以监听网络侧对第一终端设备的Uu寻呼信息。这样，可以保持两个终端设备的寻呼信息的可达性，避免丢失寻呼信息，并且，两个终端设备的DRX参数做到了协同配置(交替进入激活态)，提升了节能效果。
可选的，第二信息还可以包括指示信息，指示信息用于指示第一终端设备是否根据第四DRX参数进行寻呼监听。以第一终端设备为Remote UE，第二终端设备为Relay UE为例，当Remote UE的Uu DRX周期(即第四DRX参数指示的DRX周期)较大而Relay UE的Uu DRX周期(即第五DRX参数指示的DRX周期)较小，此时指示信息可以指示Remote UE不根据第四DRX参数进行寻呼监听，由Relay UE负责监听网络设备对两者的寻呼信息，即由Relay UE代替Remote UE监听寻呼信息。这样，当Remote UE处于网络覆盖范围外时，可以通过Relay UE获取网络设备对自身的寻呼信息，避免造成Remote UE的寻 呼丢失。
在另一种可能的实现方式中，如果可以联合配置两者的DRX参数(例如，两者的DRX参数差异不大，比如第一终端设备的第一DRX参数用于指示DRX周期时长为10s，DRX休眠期时长为5s；第二终端设备的第二DRX参数用于指示DRX周期时长为12s，DRX休眠期时长为6s)，接入网设备可以为第一终端设备和第二终端设备确定一个共同的DRX参数，即第六DRX参数。第六DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信。第六DRX参数可以是根据第一DRX参数和第二DRX参数确定的。
在一种可能的实现方式中，当Remote UE不在覆盖范围内时，可以通过Relay UE与网络侧进行通信，即由Relay UE代替Remote UE接收网络侧对Remote UE的寻呼信息，如果Relay UE的Uu DRX过长，网络侧可能无法及时寻呼到Relay UE，导致难以保障Remote UE的业务需求。因此，可以设置第六DRX参数为第一DRX参数和第二DRX参数中周期较小(短)的一个。这样，可以避免Remote UE的寻呼丢失，能够保障Remote UE的业务需求。
803、接入网设备向第一终端设备发送第二信息。
示例性的，接入网设备可以向第一终端设备发送RRC消息，RRC消息中包含第二信息。
804、第一终端设备从接入网设备接收第二信息。
示例性的，第一终端设备可以接收接入网设备发送的RRC消息，RRC消息中包含第二信息。
805、第一终端设备通过侧行链路向第二终端设备发送第二类型的DRX参数。
第一终端设备与第二终端设备通信时，可以根据第二类型的DRX参数进入休眠态，不需要一直保持Sidelink通信接口，从而可以降低通信能耗。
第一终端设备与第二终端设备还可以通过侧行链路交换对方的RNTI，RNTI例如可以是P-RNTI或者是非活跃态RNTI(Inactive-RNTI)亦或者是TMSI(如S-TMSI)，以便进行后续的下行寻呼。当第一终端设备进入激活态时，不仅可以监听网络侧对自身的寻呼，而且可以根据第二终端设备的RNTI为第二终端设备监听寻呼信息(即确定网络侧是否发送了携带第二终端设备的RNTI的寻呼消息)，避免第二终端设备的寻呼丢失，能够保障第二终端设备的业务需求。或者，当第二终端设备进入激活态时，不仅可以监听网络侧对自身的寻呼，而且可以根据第一终端设备的RNTI为第一终端设备监听寻呼信息，避免第一终端设备的寻呼丢失，能够保障第一终端设备的业务需求。同时，第一终端设备与第二终端设备还可以通过侧行链路完成定时器(例如，drx-onDurationTimer)的同步。
在一种可能的实现方式中，第一终端设备还可以通过侧行链路向第二终端设备发送第四DRX参数与第五DRX参数。若第四DRX参数与第五DRX参数指示的DRX周期时长相同，但第四DRX参数指示的DRX激活期与第五DRX参数指示的DRX激活期不相互重叠，则第一终端设备和第二终端设备可以在不同时间进入激活态。无论哪个终端设备进入激活态，都可以同时监听网络侧对两个终端设备(第一终端设备和第二终端设备)的Uu寻呼信息。示例性的，如果第一终端设备在第四DRX参数指示的激活态期间监听到网络侧对第二终端设备的寻呼信息，可以通过服务请求(service request)流程获取对应的下行 数据(MT data)，并可以根据第二类型的DRX参数，在对应的Sidelink激活态期间通过Sidelink通信寻呼第二终端设备；第二终端设备接收到第一终端设备的Sidelink寻呼后，可以与第一终端设备建立通信链路并接收第一终端设备从网络侧获取的下行数据。类似的，如果第二终端设备在第五DRX参数指示的激活态期间监听到网络侧对第一终端设备的寻呼信息，可以通过service request流程获取对应的下行数据，并可以根据第二类型的DRX参数在对应的Sidelink激活态期间通过Sidelink通信寻呼第一终端设备；Relay接收到第二终端设备的Sidelink寻呼后，可以与第二终端设备建立通信链路并接收第二终端设备从网络侧获取的下行数据。
基于本申请提供的方法，第一终端设备可以向接入网设备发送第一类型的DRX参数后，接入网设备可以根据第一类型的DRX参数确定第二类型的DRX参数并发送给第一终端设备。其中，第一类型的DRX参数用于第一终端设备与网络设备之间的通信以及第二终端设备与网络设备之间的通信，第二类型的DRX参数用于第一终端设备与第二终端设备之间的通信。这样，第一终端设备与第二终端设备通信时，可以根据第二类型的DRX参数进入休眠态，从而可以降低通信能耗。
