移动通信技术的更新换代,势必会给各行各业带来许多创新应用,移动宽带、多媒体、机器类通信(machine type communication,MTC)、工业控制、和智能交通系统(intelligent transportation system,ITS)将成为5G(5 generation)时代的主要用例。为了满足广泛变化的业务需求,5G网络将以灵活的方式构建。其中,一种潜在的方向是网络功能分离,即控制面(control plane,CP)和用户面(user plane,UP)功能分离,CP中的移动性管理(mobility management,MM)和会话管理(session management,SM)功能分离。
在5G的网络切片(network slice)中,网络切片技术是将一个物理网络切割成多个虚拟的端到端的网络,每个虚拟网络之间,包括虚拟网络内的设备、接入技术、传输路径和核心网,是逻辑独立的。每个网络切片由一个独立的网络功能或功能组合实例化构成,具备不同的功能特点,面向不同的需求和服务。网络切片的分离使得不同用户、用户组可以根据其不同应用场景和需求灵活、动态的定义和定制网络能力,而相互间不影响。
一般地,一个网络切片包括控制面功能(control plane function,CPF)实体和用户面功能(user plane function,UPF)实体。CPF实体主要完成用户设备(user equipment,UE)的接入鉴权、安全加密、位置注册等接入和移动性管理功能(access and mobility management function,AMF),以及用户面传输路径的建立、释放和更改等会话管理功能(session management function,SMF);UPF实体主要完成用户面数据的路由转发等功能。
而在5G网络架构下的临近通信5接口(prose communication 5,PC5)通信中,不管是对于网络设备为终端设备的PC5通信调度PC5通信资源的PC5通信模式(例如模式1,模式3),还是对于无需网络设备实时调度,由发送(Tx)终端设备在网络设备预配置的PC5通信资源中竞争PC5通信资源的PC5通信模式(例如,模式2,模式4),对于发送终端设备和接收(Rx)终端设备之间的PC5通信,当发送终端设备需要向接收终端设备发送数据时,不考虑接收终端设备的状态而直接通过PC5通信资源发送数据,因此接收终端设备需要持续在PC5接口上监听待接收的数据(或信号),这会导致接收终端设备过度耗电等问题。

另外,需要理解,在本申请实施例中,至少一个还可以描述为一个或多个,多个可以是两个、三个、四个或者更多个,本申请不做限制。在本申请实施例中,“/”可以表示前后关联的对象是一种“或”的关系,例如,A/B可以表示A或B;“和/或”可以用于描述关联对象存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况,其中A,B可以是单数或者复数。为了便于描述本申请实施例的技术方案,在本申请实施例中,可以采用“第一”、“第二”等字样对功能相同或相似的技术特征进行区分。该“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。在本申请实施例中,“示例性的”或者“例如”等词用于表示例子、例证或说明,被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念,便于理解。
本申请旨在解决在进行V2X业务的PC5通信时,由于发送终端设备总是发送待发送的数据,使得接收终端设备需要持续监听待接收的数据,导致接收终端设备过度耗电的问题。具体的,本申请在终端设备之间进行V2X业务的PC5通信时,引入DRX参数,使得接收终端设备可以周期性的进入睡眠状态,不在PC5接口上监听待接收的数据,需要监听的时候,则从睡眠状态中唤醒在PC5接口上监听待接收的数据,从而避免过度耗电。
对于DRX参数,本申请提出两种可能的协商方案,方案一:直接协商终端设备之间的V2X业务相关的DRX参数,再将该DRX参数通知给网络设备;方案二:先协商终端设备和网络设备之间的DRX参数,再基于终端设备和网络设备之间的DRX参数协商终端设备之间的V2X业务相关的DRX参数。其中,可选的,当使用不需要网络设备参与PC5接口资源调度的PC5通信模式时,两个终端之间直接协商终端设备之间的V2X业务相关的DRX参数,而不需要和网络设备通信,即不需要将该DRX参数通知给网络设备,也不需要基于终端设备和网络设备之间的DRX参数协商终端设备之间的V2X业务相关的DRX参数。
下面结合附图详细说明本申请实施例。
方案一:
图3为本申请实施例提供的一种通信方法流程示意图,该方法包括:
S301:第一终端设备根据第一V2X业务的传输要求,确定第一DRX参数。
其中,所述传输要求包括服务要求和/或消息模式(message pattern)。
在本申请实施例中,消息模式也可以称为业务模式(pattern),可以是指发送V2X消息的发送频率或发送周期。其中第一终端设备可以对第一终端设备进行的所有V2X业务均使用同一消息模式,也可以对第一终端设备进行的不同V2X业务使用相同或不同的消息模式。作为一种示例:第一终端设备进行任一V2X业务使用的消息模式可以均为100ms,也即第一终端设备对于任一V2X业务的V2X消息的发送周期可以均为100ms。
V2X业务的服务要求,可以是指V2X业务对应的数据包传输时延要求,如时延不超过50ms等,为了方便描述,在本申请后续描述中也可将数据包传输时延要求简称为时延要求,不再另行说明。在一种可能的实施中,V2X业务的服务要求还可以为传输V2X业务的一个或多个PC5 QoS流的QoS参数,所述QoS参数信息包括时延要求。V2X业务可能通过一个PC5 QoS流传输,也可能通过多个PC5 QoS流传输,在本申请实施例中,V2X业务的服务要求可以为传输V2X业务的一个或多个PC5 QoS流对应的一个QoS参数,也可以是传输V2X业务的一个或多个PC5 QoS流中每个PC5 QoS流的QoS参数。作为一种示例:第一V2X业务通过第一PC5 QoS流和第二PC5 QoS流传输,第一PC5 QoS流的QoS参数中包括时延不超过80ms,第二PC5 QoS流的QoS参数中包括时延不超过50ms,第一V2X业务的服务要求可以为时延不超过50ms,即一个QoS参数;也可以为第一PC5 QoS流的QoS参数(包括时延不超过80ms)和第二PC5 QoS流的QoS参数(包括时延不超过50ms)。
对于第一DRX参数的确定,需要第一DRX参数能够满足第一V2X业务的消息模式和/或服务要求。如果只考虑服务要求,假设第一V2X业务的消息模式的服务要求为时延不超过50ms,如果设置第一DRX参数为60ms,每个DRX周期中的醒来时间为5ms,由于60ms大于50ms,则当V2X消息触发后,V2X消息可能在DRX周期的非醒来时间内产生,则导致最差情况下(刚好进入睡眠态后,产生了V2X消息),V2X消息需要等55ms(DRX参数60ms减去每个DRX周期中的醒来时间5ms)之后才发出去,则满足不了时延不超过50ms的要求。作为一种示例:第一终端设备的第一V2X业务的服务要求为时延不超过50ms,则第一DRX参数可以设置为30ms,醒来时间5ms,此时最差情况下(刚好进入睡眠态后,产生了V2X消息),依旧可以获取25ms(服务要求50ms减去(第一DRX周期30ms减去5ms))的时间来传递V2X消息,从而可以较容易在服务要求50ms内发送到第二终端设备。
如果还考虑第一V2X业务的消息模式,例如,假设第一V2X业务的消息模式为100ms的发送周期、服务要求为时延不超过50ms,如果设置第一DRX参数为60ms,每个DRX周期中的醒来时间为5ms,由于睡眠时间为55ms(DRX参数60ms减去每个DRX周期中的醒来时间5ms),大于服务要求50ms,则当V2X消息触发后,最差情况下(刚好进入睡眠态后,产生了V2X消息),需要等55ms(DRX参数60ms减去每个DRX周期中的醒来时间5ms)之后才发出去,则满足不了时延不超过50ms的要求,所以应该至少设置一个小于服务要求的值,例如30ms。则假如第一DRX参数为30ms,小于100ms的发送周期,此时,终端相当于在0ms、30ms、60ms、90ms、120ms、150ms、180ms、210ms、240ms、270ms、300ms等时刻醒来,而V2X消息可能在0ms、100ms、200ms、300ms处生成,则第一条V2X消息的时刻刚好与DRX醒来时刻重叠(0ms),第二条V2X消息需要等20ms(120ms-100ms)才能被发送,第三条V2X消息需要等10ms(210ms-200ms)才能被发送, 第四条消息的时刻刚好与DRX醒来时刻重叠(300ms),再往后会以300ms最小公倍数循环。因此,最差情况是等20ms发送出去,由于服务要求为时延不超过50ms,相当于依旧可以获得30ms(时延50ms减去等待时间20ms)时间来传递V2X消息,从而可以较容易在服务要求50ms内发送到目标第二终端。
在一种可能的实施中,当第一V2X业务的服务要求包括用于传输第一V2X业务的多个PC5 QoS流的QoS参数时,第一终端设备确定的第一DRX参数可以包含用于传输第一V2X业务的每个PC5 QoS流对应的DRX参数。
以传输第一V2X业务的PC5 QoS流为第一PC5 QoS流和第二PC5 QoS流为例,第一PC5 QoS流的QoS参数(包括时延不超过80ms),第一V2X业务的消息模式为100ms的发送周期,则第一终端设备可以将第一PC5 QoS流对应的DRX参数确定为70ms或60ms等;第二PC5 QoS流的QoS参数(包括时延不超过50ms),第一V2X业务的消息模式为100ms的发送周期,则第一终端设备可以将第二PC5 QoS流对应的DRX参数确定为40ms或30ms等。
在一种可能的实施中,在第一终端设备的应用层触发第一V2X业务时,如产生第一V2X业务需要发送的V2X消息时,可以由第一终端设备的V2X层(layer)获取第一V2X业务的传输要求(服务要求和/或消息模式),并发送给第一终端设备的接入层(access stratum,AS),由第一终端设备的接入层根据第一V2X业务的传输要求,确定所述第一DRX参数。在一种可能的实施中,第一终端设备的V2X层还可以向第一终端设备的接入层发送DRX指示信息,指示第一终端设备的接入层为第一终端设备获取DRX参数。其中,第一终端设备获取第一V2X业务对应的第一DRX参数的流程可以参见上述实施,重复之处不再进行赘述。
作为一种示例,第一终端设备的V2X层获取第一V2X业务的服务要求(如传输第一V2X业务的PC5 QoS流的QoS的参数),包括:
第一终端设备上配置了以下策略/参数信息:V2X业务类型(例如供应商服务标识符(provider service identifier,PSID)或应用标识符(intelligent transport system-application identifier,ITS-AID))和/或V2X业务类型的V2X应用要求(例如优先级要求、可靠性要求、延迟要求、范围要求等),与PC5 QoS参数(即5G QoS标识(5G QoS identifier,PC5 5QI),也作PQI)和/或其他参数,如最大流比特率(maximum flow bit rate,MFBR)/保证的流比特率(guaranteed flow bit rate,GFBR)等)之间的映射关系,终端设备可以根据应用层触发的V2X业务的业务类型和/或V2X业务类型的V2X应用要求,以及终端设备上保存的上述映射关系,得到相应的PC5 QoS参数。
另外,在确定第一V2X业务的第一DRX参数时,第一终端设备还可以考虑一个或多个自身正在进行的第三V2X业务的传输要求(所述传输要求可以为服务要求和/或消息模式,也可以为具体的DRX参数),根据第一V2X业务的传输要求和一个或多个第三V2X业务的传输要求,确定第一DRX参数。其中第一终端设备正在进行的第三V2X业务可以是第一终端设备与其它终端设备(非第二终端设备)单播PC5通信的V2X业务、第一终端设备正在进行的组播PC5通信的V2X业务,第一终端设备正在进行的广播PC5通信的V2X业务中的一项或多项。
S302:所述第一终端设备向第二终端设备发送所述第一DRX参数,所述第二终端设备接收所述第一DRX参数。
其中,所述第一DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第一V2X业务的PC5通信。
第一终端设备可以将第一DRX参数携带在第一消息中,通过向第二终端设备发送携带有第一DRX参数的第一消息,将第一DRX参数发送给第二终端设备。作为一种示例,所述第一消息可以为直接通信请求(direct communication request)消息或链路修改请求(link modification request)消息或专门协商PC5 DRX参数的消息,如PC5 DRX协商请求(PC5 DRX negotiation request)消息。
示例的:如果第一终端设备和第二终端设备之间未建立有单播连接(unicast connection),则第一终端设备和第二终端设备进行单播连接的建立,此时第一终端设备可以向第二终端设备发送携带有第一DRX参数的直接通信请求消息,向第二终端设备发送第一DRX参数;如果第一终端设备和第二终端设备之间建立有单播连接,第一终端设备可以向第二终端发送携带有第一DRX参数的链路修改请求消息,向第二终端设备发送第一DRX参数。
在一种可能的实施中,第一终端设备向第二终端设备发送的第一消息中,还可以携带有第一V2X业务的传输要求或第一V2X业务的标识信息,以便第二终端设备对第一V2X业务的传输要求的获知,用于确定与第一终端设备进行第一V2X业务PC5通信的DRX参数。
S303A:所述第二终端设备向所述第一终端设备发送确认消息,所述第一终端设备接收所述确定消息,所述确认消息用于指示所述第二终端设备接受所述第一DRX参数。
S303B:所述第二终端设备向所述第一终端设备发送第二消息,所述第一终端设备接收所述第二消息,所述第二消息包括第二DRX参数。
其中,所述第二DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第一V2X业务的PC5通信。
需要理解的是,S303A和S303B互斥,即如果执行S303A则不执行S303B,如果执行S303B则不执行S303A。
第二终端设备接收到第一终端设备发送的第一DRX参数后,第二终端设备可以直接接受第一终端设备提供的第一DRX参数,根据第一终端设备提供的第一DRX参数与第一终端设备进行第一V2X业务的PC5通信。则第二终端设备向第一终端设备返回(即发送)确认消息,用于指示第二终端设备接受第一DRX参数,即执行S303A。
在一种可能的实施中,第二终端设备接收到第一终端设备发送的第一DRX参数后,第二终端设备还可以根据自身的情况,如一个或多个第二终端设备正在进行的第四V2X业务的传输要求(所述传输要求可以为服务要求和/或消息模式,也可以为具体的DRX参数),对第一DRX参数进行调整,重新确定一个新的第二DRX参数,即执行S303B。
在另一种可能的实施中,第二终端设备接收到第一终端设备发送的第一DRX参数后,第二终端设备还可以再生成一个第二DRX参数,第一DRX参数和第二DRX参数分别适用于第一终端设备和第二终端设备,也即第一终端设备基于第一DRX参数醒来接收数据,第二终端设备基于第二DRX参数醒来接收数据,即执行S303B。
对于第二DRX参数,第二终端设备可以根据自身的情况,如一个或多个第二终端设备正在进行的第四V2X业务的传输要求生成,还可以根据自身的情况,以及第一DRX参数和/或第一V2X业务的传输要求生成,其中对于第一V2X业务的传输要求,第一终端设备可以将第一V2X业务的传输要求携带在第一消息中,同第一V2X参数一同发送给第二 终端设备,也可以在第一消息中携带第一V2X业务的标识信息,由第二终端设备根据第一V2X业务的标识信息,在第二终端设备已保存的各个V2X业务的传输要求中查找第一V2X业务的传输要求,或通过与其它设备(如网络设备等)交互获知第一V2X业务的传输要求。
另外,当进行S303B时,对于第一终端设备和第二终端设备是基于第二DRX参数进行第一V2X业务的PC5通信,还是基于第一DRX参数和第二DRX参数进行PC5通信,第二终端设备可以通过其它消息告知第一终端设备,也可以在第二消息中携带指示信息指示给第一终端设备,还可以与第一终端设备预先协商,本申请实施例对此不进行限定。
其中,第二终端设备正在进行的第四V2X业务可以是第二终端设备与其它终端设备(非第一终端设备)单播PC5通信的V2X业务、第二终端设备正在进行的组播PC5通信的V2X业务,第二终端设备正在进行的广播PC5通信的V2X业务中的一项或多项。
作为一种示例:第二终端设备与第三终端设备V2X业务PC5通信使用有第六DRX参数“25ms”,第二终端设备接收到第一终端设备发送的进行第一V2X业务PC5通信的第一DRX参数“30ms”后,由于25ms<30ms,第二终端设备可以确定与第一终端设备进行第一V2X业务PC5通信的第二DRX参数为25ms,与第六DRX参数相同,此时第二终端设备可以基于相同的DRX参数同时与第一终端设备和第三终端设备进行V2X业务的PC5通信,从而可以更好地进行节电。
在另一种可能的实施中,如果携带第一DRX参数的第一消息中,还携带有第一V2X业务的传输要求,第二终端设备在确定与第一终端设备进行第一V2X业务PC5通信的第二DRX参数时,还可以根据第一V2X业务的传输要求以及一个或多个第二终端设备正在进行的第四V2X业务的传输要求确定第二参数。示例的:第二终端设备与第三终端设备V2X业务PC5通信使用有第六DRX参数“25ms”,第二终端设备接收到第一终端设备发送的进行第一V2X业务PC5通信的第一DRX参数“30ms”、第一V2X业务的消息模式“100ms”、第一V2X业务的服务要求“50ms”后,确定25ms<30ms<50ms<100ms,第二终端设备可以确定第二DRX参数为25ms。
示例的,如果第一终端设备和第二终端设备之间未建立有单播连接,第二终端设备可以通过直接通信响应(direct communication response)消息,指示第二终端设备接受第一终端设备提供的第一DRX参数,或者在直接通信响应消息中携带第二DRX参数,指示第一终端设备采用第二DRX参数或新增适用于第二终端设备的第二DRX参数,与第二终端设备进行第一V2X业务的PC5通信。也即在本申请实施例中,第二消息和确定消息可为直接通信响应消息。
如果第一终端设备和第二终端设备之间建立有单播连接,第二终端设备可以通过链路修改响应(link modification response)消息,指示第二终端设备接受第一终端设备提供的第一DRX参数,或者在链路修改响应消息中携带第二DRX参数,指示第一终端设备采用第二DRX参数或新增适用于第二终端设备的第二DRX参数,与第二终端设备进行第一V2X业务的PC5通信。也即在本申请实施例中,第二消息和确定消息也可为链路修改响应消息。
S304:所述第一终端设备和所述第二终端设备根据所述第一DRX参数和/或所述第二DRX参数,进行所述第一V2X业务的PC5通信。
情况一:如果第二终端设备接受第一终端设备发送的第一DRX参数,则第一终端设备和第二终端设备根据第一DRX参数进行所述第一V2X业务的PC5通信。
其中,对于第一V2X业务是由第二终端设备向第一终端设备单向传输的场景,第二终端设备根据第一DRX参数向第一终端设备发送第一V2X业务的数据,第一终端设备根据第一DRX参数接收第二终端设备发送的第一V2X业务的数据;对于第一V2X业务是由第二终端设备和第一终端设备双向传输的场景,第二终端设备根据第一DRX参数向第一终端设备发送第一V2X业务的数据、根据第一DRX参数接收第一终端设备发送的所述第一V2X业务的数据,第一终端设备同样根据第一DRX参数接收第二终端设备发送的第一V2X业务的数据、根据第一DRX参数向第二终端设备发送第一V2X业务的数据。
情况二:如果第二终端设备重新确定一个新的用于与第一终端设备之间进行第一V2X业务的PC5通信的第二DRX参数,则第一终端设备和第二终端设备根据第二DRX参数进行所述第一V2X业务的PC5通信。
其中,对于第一V2X业务是由第二终端设备向第一终端设备单向传输的场景,第二终端设备根据第二DRX参数向第一终端设备发送第一V2X业务的数据,第一终端设备根据第二DRX参数接收第二终端设备发送的第一V2X业务的数据;对于第一V2X业务是由第二终端设备和第一终端设备双向传输的场景,第二终端设备根据第二DRX参数向第一终端设备发送第一V2X业务的数据、根据第二DRX参数接收第一终端设备发送的所述第一V2X业务的数据,第一终端设备同样根据第二DRX参数接收第二终端设备发送的第一V2X业务的数据、根据第二DRX参数向第二终端设备发送第一V2X业务的数据。
情况三:如果第二终端设备接收到第一终端设备发送的第一DRX参数后,第二终端设备再生成一个第二DRX参数,则第一终端设备和第二终端设备根据第二DRX参数和第一DRX参数进行所述第一V2X业务的PC5通信。
此时第一终端设备和第二终端设备各自有一个醒来接收数据的DRX参数,第一终端设备第二终端设备可以进行双向传输。第二终端设备根据第二DRX参数接收第一终端设备发送的第一V2X业务的数据、根据第一DRX参数向第一终端设备发送第一V2X业务的数据,第一终端设备根据第一DRX参数接收第二终端设备发送的第一V2X业务的数据、根据第二DRX参数向第二终端设备发送第一V2X业务的数据。
需要理解的是,当第一DRX参数包括第一终端设备和第二终端设备之间的用于传输第一V2X业务的至少一个PC5 QoS流对应的DRX参数时,例如第一DRX参数包括第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数,对于上述情况一,则第一终端设备和第二终端设备基于第一PC5 QoS流对应的DRX参数,进行第一PC5 QoS流的PC5通信,第一终端设备和第二终端设备基于第二PC5 QoS流对应的DRX参数,进行第二PC5 QoS流的PC5通信。
对于上述情况二,则第二终端设备提供的第二DRX参数中包括第二终端设备新确定的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数,第一终端设备和第二终端设备基于第二终端设备新确定的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数,进行第一PC5 QoS流和第二PC5 QoS流的PC5通信。
对于上述情况三,在第二终端设备提供的第二DRX参数中包括适用于第二终端设备的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数,则第一终端设备基于第一DRX参数包括的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数接收第二终端设备发送的数据,基于第二DRX参数包括的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数向第二终端设备发送数据;第二终端设备 基于第一DRX参数包括的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数向第二终端设备发送数据,基于第二DRX参数包括的第一PC5 QoS流对应的DRX参数和第二PC5 QoS流对应的DRX参数接收第一终端设备发送的数据。
另外,可选的,当第一终端设备和第二终端设备进行第一V2X业务的PC5通信,属于网络设备为终端设备的PC5通信调度PC5通信资源的PC5通信模式(例如模式1,模式3)时,第一终端设备还可以向网络设备发送第二终端设备接受的第一DRX参数(上述情况一),或向网络设备发送第二终端设备重新确定的第二DRX参数(上述情况二),或向网络设备发送适用于第一终端设备的第一DRX参数和适用于第二网络设备的第二DRX参数(上述情况三),如通过无线资源控制(radio resource control,RRC)消息发送给网络设备,以便网络设备根据第一终端设备和第二终端设备进行的第一V2X业务PC5通信的DRX参数,为第一终端设备和第二终端设备的第一V2X业务调度PC5通信资源。
第一终端设备和第二终端设备确定进行第一V2X业务的PC5通信的第一DRX参数和/或第二DRX参数后,可以根据第一DRX参数和/或第二DRX参数,在需要监听的时候,周期性的从睡眠状态中唤醒在PC5接口上监听待接收的数据,不需要监听的时候进入睡眠状态,节约能耗。
方案二:
图4为本申请实施例提供的另一种通信方法流程示意图,该方法包括:
S401:对于网络设备调度PC5资源的PC5通信模式,第一终端设备接收来自网络设备的所述第一终端设备的第五DRX参数;或者,对于非网络设备调度PC5资源的PC5通信模式,第一终端设备本地配置第五DRX参数。
S402:所述第一终端设备根据所述第一V2X业务的传输要求,以及所述第一终端设备的第五DRX参数,确定第一DRX参数。
其中,所述传输要求包括服务要求和/或消息模式。
S403:所述第一终端设备向第二终端设备发送所述第一DRX参数,所述第二终端设备接收所述第一DRX参数。
S404A:所述第二终端设备向所述第一终端设备发送确认消息,所述第一终端设备接收所述确定消息,所述确认消息用于指示所述第二终端设备接受所述第一DRX参数。
S404B:所述第二终端设备向所述第一终端设备发送第二消息,所述第一终端设备接收所述第二消息,所述第二消息包括第二DRX参数。
其中,所述第二DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第一V2X业务的PC5通信。
需要理解的是,S404A和S404B互斥,即如果执行S404A则不执行S404B,如果执行S404B则不执行S404A。
S405:所述第一终端设备和所述第二终端设备根据所述第一DRX参数和/或所述第二DRX参数,进行所述第一V2X业务的PC5通信。
在方案二中,网络设备可以通过RRC消息等指示给第一终端设备一个基本DRX参数,即第五DRX参数,并可以基于第五DRX参数为第一终端设备调度PC5通信资源。第一终端设备需要基于网络设备调度的PC5通信资源与第二终端设备进行V2X业务的PC5通信,因此第一终端设备和第二终端设备在确定V2X业务对应的DRX参数时,需要考虑第五DRX参数,以获取相应的PC5通信资源。
或者,第一终端设备本地可以配置一个基本DRX参数,即第五DRX参数,并可以基于第五DRX参数为第一终端设备抢占PC5通信资源。第一终端设备需要基于抢占的PC5通信资源与第二终端设备进行V2X业务的PC5通信,因此第一终端设备和第二终端设备在确定V2X业务对应的DRX参数时,也需要考虑第五DRX参数,以获取相应的PC5通信资源。
在方案二中,第一终端设备确定第一DRX参数的方式和第二终端设备确定第二DRX参数的方式与方案一类似,不同之处在于第一终端设备确定第一DRX参数和第二终端设备确定第二DRX参数时,还需要考虑第五DRX参数。在一种可能的实施中,第一DRX参数和第二DRX参数为第五DRX参数的整数倍。具体的,第一终端设备确定第一DRX参数的方式和第二终端设备确定第二DRX参数的流程,以及如何基于确定的第一DRX参数和/或第二DRX进行第一V2X业务的PC5通信等流程,可以参照上述方案一中的实现,重复之处不再进行赘述。
另外,可选的,为了便于第二终端设备对第五DRX参数的获知,在第一终端设备向第二终端设备发送携带有第一DRX参数的第一消息中,还可以携带有所述第五DRX参数。
此外,对于网络设备调度PC5资源的PC5通信模式,因方案二是基于网络设备指示给第一终端设备的第五DRX参数,确定的进行第一V2X业务的第一DRX参数和/或第二DRX参数,第一终端设备可以不向网络设备上报进行第一V2X业务的第一DRX参数和/或第二DRX参数。
无论是上述方案一还是方案二,当第一终端设备和第二终端设备之间新增第二V2X业务时,第一终端设备均需要获取第二V2X业务的传输要求,并判断当前采用的第一DRX参数和/或第二DRX参数能否满足第二V2X业务的传输要求,如果第一终端设备和第二终端设备当前采用的第一DRX参数和/或第二DRX参数不能满足新增的第二V2X业务的传输要求,则需要发起对DRX参数的更新。在本申请实施例中,对DRX参数的更新有两种方式。方式一:对第一V2X业务对应的DRX参数进行更新,第一终端设备和第二终端设备的第一V2X业务和第二V2X业务基于更新后的DRX参数进行PC5通信;方式二:新增第二V2X业务的DRX参数,新增的第二V2X业务基于新增的DRX参数进行PC5通信。下面结合具体方式进行介绍。
方式一:对进行第一V2X业务对应的DRX参数进行更新,第一终端设备和第二终端设备的第一V2X业务和第二V2X业务基于更新后的DRX参数进行PC5通信(即DRX参数是PC5单播粒度的DRX参数,多个V2X业务对应相同的DRX参数)。
参照图5所示的通信方法流程示意图,该方法包括:
S501:第一终端设备根据第二V2X业务的传输要求和第一V2X业务的传输要求,向所述第二终端设备发送第四DRX参数,所述第二终端设备接收所述第四DRX参数。
其中,所述第四DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第一V2X业务和所述第二V2X业务的PC5通信。
具体的,第四DRX参数需要满足第二V2X业务的传输要求和第一V2X业务的传输要求,当网络设备指示给第一终端设备第五DRX参数或第一终端设备本地配置第五DRX参数时,还需要考虑第五DRX参数,如需要为第五DRX参数的整倍数。关于第四DRX参数的确定,可以参照上述对第一DRX参数的确定流程,重复之处不再进行赘述。
作为一种示例,第一终端设备和第二终端设备在进行第一V2X业务的PC5通信时, 已建立有单播连接,第一终端设备可以通过向第二终端发送携带有第四DRX参数的链路修改请求消息,向第二终端设备发送第四DRX参数。在一种可能的实施中,第一终端设备还可以向第二终端设备发送第二V2X业务的传输要求,如在用于发送第四DRX参数的链路修改请求消息中携带第二V2X业务的传输要求,以便第二终端设备确定与第一终端设备进行第一V2X业务和第二V2X业务PC5通信的DRX参数。
S502A:所述第二终端设备向所述第一终端设备发送第二确认消息,所述第一终端设备接收所述第二确定消息,所述第二确认消息用于指示所述第二终端设备接受所述第四DRX参数。
S502B:所述第二终端设备向所述第一终端设备发送第七DRX参数,所述第一终端设备接收所述第七DRX参数。
其中,所述第七DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第一V2X业务和所述第二V2X业务的PC5通信。
需要理解的是,S502A和S502B互斥,即如果执行S502A则不执行S502B,如果执行S502B则不执行S502A。
如果第二终端设备接受第一终端设备提供的第四DRX参数,可以向第一终端设备返回第二确认消息,用于指示第二终端设备接受第四DRX参数。
在一种可能的实施中,第二终端设备接收到第一终端设备发送的第四DRX参数后,第二终端设备还可以根据自身的情况,如一个或多个第二终端设备正在进行的第四V2X业务的传输要求(所述传输要求可以为服务要求和/或消息模式,也可以为具体的DRX参数),对第四DRX参数进行调整,重新确定一个新的第七DRX参数;或者在第四DRX参数的基础上,再确定一个第七DRX参数。
其中,第二终端设备如何确定第七DRX参数的流程可以参照上述第二终端设备确定第二DRX参数的流程,重复之处不再进行赘述。
另外,需要理解的是,当网络设备指示给第一终端设备第五DRX参数或第一终端设备本地配置第五DRX参数时,第二终端设备确定第七DRX参数时,还需要考虑第五DRX参数,如需要为第五DRX参数的整倍数。
S503:所述第一终端设备和所述第二终端设备根据所述第四DRX参数和/或所述第七DRX参数,进行所述第一V2X业务和所述第二V2X业务的PC5通信。
在方式一中,第一终端设备和第二终端设备基于新确定的第四DRX参数和/或第七DRX参数,进行第一V2X业务和第二V2X业务的PC5通信。即第一终端设备和第二终端设备之间的多个V2X业务使用相同的DRX参数,DRX参数是PC5单播粒度的DRX参数。
方式二:新增第二V2X业务的DRX参数,新增的第二V2X业务基于新增的DRX参数进行PC5通信(V2X业务粒度的DRX参数,即每个V2X业务可以对应不同的DRX参数)。
参照图6所示的通信方法流程示意图,该方法包括:
S601:第一终端设备根据第二V2X业务的传输要求,向所述第二终端设备发送第三DRX参数,所述第二终端设备接收所述第三DRX参数。
所述第三DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第二V2X业务的PC5通信。
S602A:所述第二终端设备向所述第一终端设备发送第三确认消息,所述第一终端设备接收所述第三确定消息,所述第三确认消息用于指示所述第二终端设备接受所述第三DRX参数。
S602B:所述第二终端设备向所述第一终端设备发送第八DRX参数,所述第一终端设备接收所述第八DRX参数。
其中,所述第八DRX参数用于所述第一终端设备与所述第二终端设备之间进行所述第二V2X业务的PC5通信。
需要理解的是,S602A和S602B互斥,即如果执行S602A则不执行S602B,如果执行S602B则不执行S602A。
S603:所述第一终端设备和所述第二终端设备根据所述第一DRX参数和/或所述第二DRX参数,进行所述第一V2X业务的PC5通信;根据所述第三DRX参数和/或所述第八DRX参数,进行所述第二V2X业务的PC5通信。
具体的,当新增第二V2X业务时,第一终端设备和第二终端设备协商进行第二V2X业务对应的DRX参数(第三DRX参数和/或第八DRX参数)的流程可以参照上述对第一V2X业务对应的DRX参数(第一DRX参数和/或第二DRX参数)的确定流程,重复之处不再进行赘述。另外,需要理解的是,当网络设备指示给第一终端设备第五DRX参数或第一终端设备本地配置第五DRX参数时,还需要考虑第五DRX参数,例如,为第一终端设备确定的第三DRX参数,或第二终端设备确定的第八DRX参数,需要为第五DRX参数的整倍数。
与方式一不同的是,当新增第二V2X业务时,如果现有DRX参数不能满足第二V2X业务的传输要求时,第一终端设备和第二终端设备重新协商DRX参数,用于新增第二V2X业务的PC5通信。第一终端设备和第二终端设备之间的每个V2X业务可以使用不同的DRX参数,DRX参数可以是V2X业务粒度的。
另外,需要理解的是,在本申请实施例中,对于进行V2X业务PC5通信的DRX参数可以由第一终端设备和第二终端设备的V2X层协商及确定,也可以由第一终端设备和第二终端设备的接入层协商及确定。当采用方案一时,如果是由第一终端设备和第二终端设备的V2X层协商及确定,需要将确定的DRX参数指示给第一终端设备的接入层,以便第一终端设备在DRX周期醒来向网络设备请求PC5通信资源或本地抢占PC5通信资源;如果是网络设备调度PC5通信资源的模式,则还需要由第一终端设备的接入层上报给网络设备,以便网络设备为第一终端设备调度PC5通信资源。当采用方案二时,如果是由第一终端设备和第二终端设备的V2X层协商及确定,第一终端设备的接入层获得网络设备指示给第一终端设备一个基本DRX参数(如第五DRX参数)或第一终端设备本地配置第五DRX参数后,需要将该基本DRX参数上报给第一终端设备的V2X层,以便基于该基本DRX参数与第二终端设备协商进行V2X业务PC5通信的DRX参数。
此外,如果进行V2X业务PC5通信的DRX参数是由第一终端设备和第二终端设备的V2X层协商及确定,第二终端设备还需将确定的DRX参数发给第二终端设备的接入层,以便第二终端设备在DRX周期醒来在PC5接口上监听V2X业务的待接收数据,以达到节能效果。
上述主要是从第一终端设备和第二终端设备之间进行V2X业务的单播PC5通信的角度进行描述的,对于第一终端设备进行V2X业务的组播PC5通信或广播PC5通信,在第 一终端设备确定V2X业务的DRX参数,并通过组播或广播发送给一个或多个第二终端设备后,所述一个或多个第二终端设备可以直接基于第一终端设备发送的DRX参数与第一终端设备进行V2X业务的PC5通信。
作为一种示例,第一终端设备确定第一V2X业务(组播或广播业务)的第一DRX参数后,通过广播或组播消息发送给一个或多个第二终端设备后,所述一个或多个第二终端设备可以根据第一DRX参数向第一终端设备发送第一V2X业务的数据,第一终端设备可以根据第一DRX参数接收所述一个或多个第二终端设备发送的第一V2X业务的数据。其中,对于第一V2X业务的第一DRX参数确定,可以参照上述方案一或方案二中的实施,重复之处不再赘述。
作为另一种示例,当第一终端设备正在进行一个或多个V2X业务时,第一终端设备还可以根据正在进行的一个或多个V2X业务(包括单播V2X业务、组播V2X业务和广播V2X业务)的传输要求以及第一V2X业务(组播或广播业务)的传输要求,确定一个满足所述一个或多个V2X业务以及第一V2X业务的传输要求的DRX参数,作为第一V2X业务的第一DRX参数,并通过组播或广播发送给一个或多个第二终端设备,所述一个或多个第二终端设备可以根据第一DRX参数向第一终端设备发送第一V2X业务的数据,第一终端设备可以根据第一DRX参数接收所述一个或多个第二终端设备发送的第一V2X业务的数据。
在另一种可能的实施中,对于第一终端设备进行V2X业务的组播PC5通信或广播PC5通信,包括发送和/或接收组播PC5通信业务或广播PC5通信业务,对于第一终端设备确定V2X业务的DRX参数和其它需要进行V2X业务的组播PC5通信或广播PC5通信的终端设备确定V2X业务的DRX参数,各个终端设备可以采用相同的DRX参数生成策略,为特定V2X业务生成的DRX参数,由于所有终端设备的特定V2X业务的传输要求都相同,因此各个终端设备为特定V2X业务生成的DRX参数也一样,因此第一终端设备可以无需通过组播或广播将自己的DRX参数发送给其它终端设备。即第一终端设备可以直接基于第一终端设备生成的DRX参数与其它终端设备进行V2X业务的PC5通信,包括为其感兴趣的V2X业务发送和/或接收组播PC5通信业务或广播PC5通信业务。
