Description

一种通信方法以及相关装置
本申请要求于2021年06月25日提交中国国家知识产权局、申请号为202110713686.9、发明名称为“一种通信方法以及相关装置”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
本申请涉及通信技术领域,尤其涉及一种通信方法以及相关装置。
背景技术
在移动通信系统中,来自第五代移动通信技术(5G)核心网的寻呼称作5GC寻呼(paging)。处于空闲态(RRC_IDLE状态)的用户设备(user equipment,UE)有下行数据到达时,5GC触发寻呼该UE,用户设备也称为终端设备或者终端。最终的寻呼消息都由网络设备(例如:下一代节点(Next Generation Node B,gNB))通过空口下发给UE。寻呼流程指的是网络设备周期性的向UE发送寻呼消息,通知UE执行相应的操作或者更新相关的参数,UE处于空闲态(RRC_IDLE)或者非激活态(RRC-INACTIVE)或者连接态(RRC_CONNECTED)下的时候都可以接收寻呼消息。
现有的终端在空闲态或者非激活态仍需要周期性监听寻呼以及测量等操作,对于超低功耗要求的终端(如可穿戴设备),存在耗电量较大的问题。为了解决这个问题,5G技术中还引入了唤醒信号(wake up signal,WUS)技术。在WUS技术中,首先,终端设备与网络设备协商监听WUS的时间。其次,终端设备在每个非连续接收(Discontinuous Reception,DRX)周期对应的寻呼机会(paging occasion,PO)前监听WUS,该WUS指示终端在接下来的PO中被寻呼。监听到该WUS的终端,在该WUS后的一个或多个PO中监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)并接收寻呼消息。
然而,WUS技术中终端仍然需要开启监听功能,才能成功监听到WUS。因此仍然存储功耗较大的问题。
发明内容
本申请实施例提供了一种通信方法。通过引入低功耗的第一状态,节省了终端设备的功耗。通过多种方式可以唤醒处于第一状态的终端设备,以保证终端设备的业务正常运行。相较于现有的WUS技术,终端设备减少了监听PDCCH的时间,进一步降低终端设备的功耗。终端设备还可以通过低功耗收发电路监听唤醒信息,进一步降低终端设备的功耗。

在另一种可能的实现方式中,第一状态与正常的空闲态并列,第一状态、空闲态和连接态共同组成了终端设备的状态。终端设备的状态可以分为第一状态、连接态和空闲态。其中该空闲态即现有协议定义的空闲态。需要说明的是,该终端设备的状态指的是终端设备与AMF之间信令的连接状态。
在另一种可能的实现方式中,第一状态与正常的非激活状态并列,第一状态、非激活状态、空闲态和连接态共同组成了终端设备的状态,非激活状态也称为非激活态。非激活状态为的“正常的非激活状态”,该第一状态也可以称为瞌睡状态或睡眠状态。需要说明的是,该终端设备的第一状态指的是终端设备与接入网设备之间信令的连接状态。
本申请实施例中,通过引入低功耗的第一状态,节省了终端设备的功耗。通过多种方式可以唤醒处于第一状态的终端设备,以保证终端设备的业务正常运行。相较于现有的WUS技术,终端设备减少了监听PDCCH的时间,进一步降低终端设备的功耗。终端设备还可以通过低功耗收发电路监听唤醒信息,进一步降低终端设备的功耗。

在一种可能的实现方式中,在第一状态中,不执行同频测量、异频测量、小区测量和/或小区重选。通过限制处于第一状态的终端设备的行为,进一步降低终端设备的功耗。
在一种可能的实现方式中,在第一状态中,终端设备类似处于关机状态。在第一状态中,终端设备维持与核心网设备的注册和空口配置,该空口配置包括但不限于优先级配置。在第一状态中,终端设备不执行同频测量、异频测量、小区测量和/或小区重选等空闲态行为。通过限制处于第一状态的终端设备的行为,进一步降低终端设备的功耗。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如,第一信息和第二信息仅仅是为了区分不同的信息,并不对其先后顺序进行限定。本领域技术人员可以理解“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。

为便于理解本申请实施例提供的通信方法,下面将对本申请实施例提供的通信方法的系统架构和应用场景进行说明。可理解的,本申请实施例描述的系统架构和应用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。
图1为本申请的实施例应用的通信系统1000的架构示意图。如图1所示,该通信系统包括无线接入网100和核心网200,可选地,通信系统1000还可以包括互联网300。其中,无线接入网100可以包括至少一个接入网设备(如图1中的110a和110b),还可以包括至少一个终端(如图1中的120a-120j)。终端通过无线的方式与接入网设备相连,接入网设备通过无线或有线方式与核心网连接。核心网设备与接入网设备可以是独立的不同的物理设备,也可以是将核心网设备的功能与接入网设备的逻辑功能集成在同一个物理设备上,还可以是一个物理设备上集成了部分核心网设备的功能和部分的接入网设备的功能。终端和终端之间以及接入网设备和接入网设备之间可以通过有线或无线的方式相互连接。图1只是示意图,该通信系统中还可以包括其它网络设备,如还可以包括无线中继设备和无线回传设备,在图1中未画出。

终端还可以称为终端设备、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等,其可以是用户侧的一种用于接收或发射信号的实体,如手机。终端设备可以是用户设备(user equipment,UE),其中,UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地,UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。终端可以广泛应用于各种场景,例如,设备到设备(device-to-device,D2D)、车物(vehicle to everything,V2X)通信、机器类通信(machine-type communication,MTC)、物联网(internet of things,IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请实施例中,用于实现终端的功能的装置可以是终端;也可以是能够支持终端实现该功能的装置,例如芯片系统、或通信模块、或调制解调器等,该装置可以被安装在终端中。本申请实施例中,芯片系统可以由芯片构成,也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中,以用于实现终端的功能的装置是终端,以终端是UE为例,描述本申请实施例提供的技术方案。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。

基站和终端的角色可以是相对的,例如,图1中的直升机或无人机120i可以被配置成 移动基站,对于那些通过120i接入到无线接入网100的终端120j来说,终端120i是基站;但对于基站110a来说,120i是终端,即110a与120i之间是通过无线空口协议进行通信的。当然,110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的,此时,相对于110a来说,120i也是基站。因此,基站和终端都可以统一称为通信装置,图1中的110a、110b以及120a-120j可以称为具有它们各自相对应的功能的通信装置,例如具有基站功能的通信装置、或者具有终端功能的通信装置。
基站和终端之间、基站和基站之间、终端和终端之间可以通过授权频谱进行通信,也可以通过免授权频谱进行通信,也可以同时通过授权频谱和免授权频谱进行通信;可以通过6千兆赫(gigahertz,GHz)以下的频谱进行通信,也可以通过6GHz以上的频谱进行通信,还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。

上述内容简要阐述了本申请实施例的系统架构和可能的应用场景,为更好地理解本申请实施例的技术方案。下面对本申请实施例涉及的一些背景技术进行介绍。
1、通信状态:
对于终端设备在通信系统中的三种状态:根据终端设备与核心网的连接状态可以将终端设备所处的状态分为空闲态(idle)、非激活态(inactive)和连接态(connected)。其中,终端设备处于连接态时,终端设备可以通过基站动态调度与基站进行通信,传输数据。终端设备处于空闲态时,若终端设备需要传输数据,则终端设备需要先进行随机接入,与基站建立RRC连接之后才可以进行数据传输,或在随机接入过程中的消息3(message 3,Msg3)中传输上行信息。终端设备处于非激活态时,终端设备与核心网侧都保留了终端设备处于连接态时RRC消息的上下文。若终端设备需要传输数据,则终端设备可以根据保留的RRC消息的上下文更快的接入连接态,从而实现数据传输。
2、寻呼:
寻呼(Paging)是指网络设备在寻找终端,例如当网络设备有下行信息需要发送时,网络设备会向终端发送Paging信息,该Paging信息中携带有终端的标识。如果终端检测自身的标识在上述Paging信息中,则终端会向网络设备发送请求以接入网络中。处于空闲(idle)状态的终端会在特定的时频资源上监听下行控制信息(downlink control information,DCI),若终端监听到有Paging信息下发,则终端根据DCI中的指示接收Paging信息。其中,上述监听Paging信息对应的DCI使用的特定的时域资源称之为寻呼机会(paging occasion,PO),寻呼机会也称之为寻呼时刻。在PO上检测DCI的时刻通常称之为物理下行控制信道(physical downlink control channel,PDCCH)检测时刻,在PO上检测DCI也称为监听PDCCH。
3、唤醒信号(wake up signal,WUS)。
现有的唤醒信号流程,请参阅图5,图5为本申请实施例中提出的一种唤醒信号流程示意图。唤醒信号的流程,包括:
501、终端设备上报WUS能力。
终端设备上报自身支持的WUS能力。该WUS能力包括但不限于唤醒时间,唤醒时间指的是终端设备唤醒后监听唤醒信号的时间。
502、接入网设备向终端设备发送WUS配置信息。
该WUS配置信息包括但不限于:
(1)WUS的最大持续时间信息,其用于指示唤醒信号WUS的最大持续发送时间;
(2)PO数,其用于指示关联到一个WUS的PO个数;
(3)UE组数,其用于指示关联到一个WUS的UE的分组个数,或用于指示关联一个PO的UE的分组个数;
(4)频率位置信息,用于指示发送WUS的频率位置;
(5)时间位置信息,用于指示发送WUS的时间位置;在一种可能的实施方式中,时间位置信息可以用于指示发送WUS相对于PO的时间位置,如发送WUS的结束时刻与所关联第一个PO的时间。
503、终端设备基于WUS能力和WUS配置信息,接收WUS。
终端设备基于自身的WUS能力和来自接入网设备的WUS配置信息,接收WUS。
504、当终端设备接收WUS之后,终端设备监听PDCCH以及接收寻呼消息。
当终端设备接收到来自接入网设备的WUS之后,终端设备监听PDCCH以及接收寻呼消息。当终端设备未接收到来自接入网设备的WUS,则终端设备不监听PDCCH。
在上述WUS流程中,终端设备需要在每个DRX周期的相应PO中监听是否有寻呼消息或者系统消息变化通知。因此,在每个PO之前引入WUS,该WUS指示终端设备是否在接下来的一个或多个PO中被寻呼。只有接收到WUS的终端设备才是被寻呼的终端设备,被寻呼的终端设备在PO内监听PDCCH以及接收寻呼消息。
而监听WUS的流程与监听寻呼消息对应的PDCCH相比,仅是在监听的重复次数或者监听时长上减少了一部分,功耗上并没有大幅减小。基于此,本申请提出一种通信方法,应用于终端设备、接入网设备和/或核心网设备。下面结合附图进行说明。
请参阅图6,图6为本申请实施例提出的一种通信方法的流程示意图。本申请实施例提出的一种通信方法包括:
601、终端设备接收来自接入网设备的第一信息。
接入网设备向终端设备发送第一信息,终端设备根据第一信息进入第一状态。
可选地,第一信息中可以包含重定向的指示信息,以及重定向指示的小区或者频点是否支持终端在第一状态。
可选地,第一信息中包括支持配置第一状态的小区或者频点信息。
可选地,该第一信息还可以包括寻呼概率,则该第一信息指示相同寻呼概率的终端设备进入第一状态。示例性的,当第一信息包括的寻呼概率为0.75,则接收到该第一信息的终端设备中寻呼概率为0.75的终端设备进入第一状态。又一种示例中,当第一信息包括的寻呼概率为(0.75-1],则接收到该第一信息的终端设备中寻呼概率在(0.75-1]区间内的终端设备进入第一状态。
可选地,第一信息可以携带在RRC释放消息中或者第一信息为RRC连接释放消息。
602、终端设备进入第一状态。
当终端设备接收到第一信息后,终端设备可以直接进入第一状态,终端设备也可以等待一段时间后进入第一状态。该等待的时间由第一状态的计时器的时长确定。定时器可以是接入网设备配置给终端;也可以是核心网设备配置给终端的,例如:核心网设备通过接入网设备向终端设备配置该定时器。示例性的,当第一状态的计时器的时长为5秒。则终端设备在接收第一信息之后,开启第一状态的计时器。在第一状态的计时器开启5秒后,终端设备进入第一状态。
下面介绍本申请实施例提出的第一状态。第一状态是一种终端设备的状态。
在一种可能的实现方式中,在第一状态中,终端设备类似处于关机状态。在第一状态中,终端设备维持与核心网设备的注册和空口配置,该空口配置包括但不限于优先级配置。在第一状态中,终端设备不执行同频测量、异频测量、小区测量和/或小区重选等空闲态行为。通过限制处于第一状态的终端设备的行为,进一步降低终端设备的功耗。
在另一种可能的实现方式中,在第一状态中,终端设备类似处于关机状态。在第一状态中,终端设备维持与核心网设备的注册和空口配置,该空口配置包括但不限于优先级配置。在第一状态中,终端设备执行放松的同频测量、放松的异频测量、放松的小区测量和/ 或放松的小区重选等空闲态行为。该放松的同频测量/异频测量/小区测量含义为:相较于现有协议定义的空闲态或非激活态中的同频测量/异频测量/小区测量,该放松的同频测量/异频测量/小区测量的测量周期较长,例如进行测量的DRX周期的数量较大。该放松的小区重选含义为:相较于现有协议定义的空闲态或非激活态中的小区重选,该放松的小区重选中触发小区重选或者触发测量小区的阈值较低。通过限制处于第一状态的终端设备的行为,进一步降低终端设备的功耗。
在第一状态中,终端设备不接收来自接入网设备的以下一项或多项信息:寻呼消息、同步消息或者系统消息或者参考信号。在第一状态中,终端设备接收唤醒信息,该唤醒信息包括但不限于唤醒信号(wake up signal),唤醒指示(wake up indicator),或者其它指示。可选地,终端设备中的低功耗收发电路用于接收上述唤醒信息。可选地,在第一状态中,终端设备不接收除唤醒信息以外的其它下行数据。
在一种可能的实现方式中,第一状态是空闲态的一个子集。为了便于理解,请参阅图8,图8为本申请实施例提出的第一状态的一种示意图。第一状态与现有协议定义的空闲态共同组成了空闲态,本申请实施例中将现有协议定义的空闲态称为正常的空闲态。具体的,终端设备的状态可以分为连接态和空闲态,其中,空闲态包括第一状态和正常的空闲态。需要说明的是,该终端设备的状态指的是终端设备与AMF之间信令的连接状态。该正常的空闲态也可以称为苏醒状态(awake state),该第一状态也可以称为瞌睡状态(doze state)。
在另一种可能的实现方式中,第一状态与正常的空闲态并列,第一状态、空闲态和连接态共同组成了终端设备的状态。为了便于理解,请参阅图9,图9为本申请实施例提出的第一状态的又一种示意图。终端设备的状态可以分为第一状态、连接态和空闲态。其中该空闲态即现有协议定义的空闲态,也就是图8中的“正常的空闲态”。需要说明的是,该终端设备的状态指的是终端设备与AMF之间信令的连接状态。
在另一种可能的实现方式中,第一状态与正常的非激活状态并列,第一状态、非激活状态、空闲态和连接态共同组成了终端设备的状态,非激活状态也称为非激活态。非激活状态为的“正常的非激活状态”,该第一状态也可以称为瞌睡状态或睡眠状态。需要说明的是,该终端设备的第一状态指的是终端设备与接入网设备之间信令的连接状态。
603、终端设备在第一状态中接收来自接入网设备的唤醒信息。
可选地,当接入网设备向终端设备发送唤醒信息后,终端设备可以向接入网设备发送反馈信息。该反馈信息可以包括唤醒信息的部分或全部信息。该反馈信息指示终端设备成功接收唤醒信息。
接入网设备收到来自终端设备的反馈信息后,接入网设备继续执行后续流程,例如:向终端设备发送寻呼消息或者向终端设备发送下行数据。当接入网设备向终端设备发送唤醒信息后,在一段时间内,接入网设备未收到来自终端设备的反馈信息,则接入网设备确认此次唤醒终端设备失败(即指示终端设备离开第一状态失败)。接入网设备提升该唤醒信息的功率后,向终端设备发送该提升功率的唤醒信息。或者,接入网设备重复发送该唤醒信息,例如:接入网设备重复5次发送该唤醒信息。或者,接入网设备降低调制与编码策略(Modulation and Coding Scheme,MCS)的调制阶数后,向终端设备发送该唤醒信息。
可选地,接入网设备可以根据终端设备上报的第二信息,确定在当前的PO中是否有充足的时间唤醒终端设备(即向终端设备发送唤醒信息,并指示终端设备离开第一状态)。若时间充足,则接入网设备在当前PO中重新发送唤醒信息。若时间不充足,则接入网设备在下一个PO或者其它PO中向终端设备发送该唤醒信息。
关于该唤醒信息,该唤醒信息可以包括终端设备的标识,和/或终端设备的组标识。该唤醒信息包括的终端设备的标识指示对应的终端设备离开第一状态。
可选地,该唤醒信息包括的终端设备的组标识指示对应的一组终端设备离开第一状态或进入正常的空闲态或非激活态或连接态。
可选地,唤醒信息中包含一些配置信息,收到该信息的终端根据自身情况判断是否需要离开第一状态。即不是收到唤醒信息立刻离开该状态。
可选地,该唤醒信息包括的终端设备的组标识指示对应的一组终端设备可能可以离开第一状态,该组终端设备中具体的某个终端设备是否离开第一状态还需要根据来自接入网设备的寻呼消息的指示。例如:当唤醒信息包括终端设备的组标识时,接收到该唤醒信息的终端设备首先判断自身是否属于该组标识对应的分组。若属于,则终端设备监听寻呼消息,当该寻呼消息包括该终端设备的标识,则终端设备发起接入网络流程;当该寻呼消息不包括该终端设备的标识,则终端设备继续保持第一状态。
604、终端设备离开第一状态。
终端设备可以根据多种条件离开第一状态,下面分别进行说明:
在第一状态中,当终端设备接收来自接入网设备的唤醒信息后,终端设备根据该唤醒信息离开第一状态。该指示终端设备离开第一状态的唤醒信息可以是某一类特殊的唤醒信息,例如唤醒指示。
在第一状态中,当终端设备的第一状态的计时器超时,且终端设备未接收到来自接入网设备的唤醒信息,终端设备离开第一状态。
在第一状态中,当终端设备在连续N次寻呼机会(或N个寻呼周期内)中未收到来自接入网设备的唤醒信息时,终端设备离开第一状态,N为正整数。
离开第一状态后,终端设备可以直接接入网络。例如:当唤醒信息包括该终端设备的标识时,终端设备根据该终端设备的标识直接接入网络。当唤醒信息包括该终端设备的组标识时,终端设备根据该终端设备的组标识直接接入网络。
离开第一状态后,终端设备也可以接收来自接入网设备的寻呼消息,并发起接入网络的流程。例如:当唤醒信息包括终端设备的组标识时,接收到该唤醒信息的终端设备首先判断自身是否属于该组标识对应的分组。若属于,则终端设备监听寻呼消息,当该寻呼消息包括该终端设备的标识,则终端设备发起接入网络流程;当该寻呼消息不包括该终端设备的标识,则终端设备继续保持第一状态。
本申请实施例中,通过引入低功耗的第一状态,节省了终端设备的功耗。通过多种方式可以唤醒处于第一状态的终端设备,以保证终端设备的业务正常运行。相较于现有的WUS技术,终端设备减少了监听PDCCH的时间,进一步降低终端设备的功耗。终端设备还可以通过低功耗收发电路监听唤醒信息,进一步降低终端设备的功耗。
结合前述图6所示实施例,请参阅图7,图7为本申请实施例提出的一种通信方法的又一种流程示意图。本申请实施例提出的一种通信方法包括:

702a、终端设备向接入网设备发送第一请求消息。
步骤702a-702b中,终端设备向核心网设备发送第一请求消息。具体的,终端设备通过接入网设备向核心网设备发送第一请求消息。终端设备可以请求网络侧配置第一状态,避免终端设备与网络侧之间因为不兼容的问题而导致终端设备无法进入第一状态。或者终端设备因为移动至不支持第一状态的区域范围导致的无法离开第一状态。
下面对步骤702a进行描述:终端设备向接入网设备发送第一请求消息,该第一请求消息用于请求配置第一状态。该第一请求消息包括以下一项或多项信息:请求配置第一状态的计时器的时长,或者请求配置N次寻呼机会(或N个寻呼周期),N为正整数,N指示终端设备的最大连续寻呼机会。

核心网设备收到来自终端设备的第一请求消息之后,核心网设备为终端设备进行配置。具体的,核心网设备通过接入网设备向终端设备发送第一配置信息,该第一配置信息用于配置终端设备的第一状态。
第一配置信息包括以下一项或多项信息:第一状态的计时器的时长,终端设备的组标识,终端设备的标识,或者N次寻呼机会(或N个寻呼周期)。具体的,向该终端设备的标识对应的终端设备配置第一状态。例如:当第一配置信息包括的终端设备的标识为“UE1”时,第一配置信息向终端设备的标识“UE1”对应的终端设备(例如终端设备1)配置第一状态。
或者,向该终端设备的组标识对应的一个或多个终端设备配置第一状态。例如:当第一配置信息包括的终端设备的组标识为“group1”时,第一配置信息向组标识“group1”对应的终端设备(例如终端设备1、终端设备2和终端设备3)配置第一状态。
可选地,第一状态的计时器的时长可以与TAU计时器(timer)相同。
可选地,第一状态的计时器的时长也可以与实际业务相关。即可能等于业务到达周期。
示例性的,该第一配置信息可以携带在注册接收消息中,或者,该第一配置信息可以携带在跟踪区更新接收消息中,此处不作限制。
下面对本申请实施例涉及的终端设备的标识和终端设备的组标识进行说明,通过多种方式标识终端设备,提升了方案的实现灵活性。可以降低信令开销,降低唤醒终端设备的时延:
终端设备的标识可以是5G全球位移临时标识符(5G Globally Unique Temporary UE Identity,5G-GUTI),5G-GUTI包括全局唯一的AMF标识符(globally unique AMF identifier,GUAMI)和5G临时移动用户识别码(5G Temporary Mobile Subscriber Identity,5G-TMSI),其中,GUAMI指示为该终端设备提供服务的AMF。
该终端设备的标识还可以是5G-S-TMSI,5G-S-TMSI为5G-GUTI的缩短形式。5G-S-TMSI包括AMF所在集合的标识(AMF set ID)、AMF的指示(AMF pointer)和5G-TMSI。
该终端设备的标识还可以是接入网设备分配的无线网络临时标识(radio network temporary identifier,RNTI),例如是:完整的RNTI或者截断的RNTI,该截断的RNTI为完整的RNTI的一部分,例如是完整的RNTI的部分比特。示例性的,该终端设备的标识可以是完整的非激活态无线网络临时标识(full inactive-radio network temporary identifier,fullI-RNTI),该终端设备的标识也可以是fullI-RNTI的部分比特。
终端设备的组标识可以是核心网设备按照服务(service)分配的服务标识,同一服务的终端设备分配至同一组。
终端设备的组标识还可以是核心网设备按照会话(session)分配的会话标识,使用同一会话的终端设备分配至同一组。
终端设备的组标识还可以是核心网设备根据终端设备的寻呼概率分配的组标识,其中,相同寻呼概率范围内的终端设备分配至同一组。该寻呼概率范围指示终端设备被寻呼的概 率属于该范围区间。该寻呼概率可以由终端设备与核心网设备协商得到,为了便于理解,请参阅图10,图10为本申请实施例中一种寻呼概率的分组示意图。如图10所示,示例性的,寻呼概率为[0-0.25)的终端设备分配至分组1,寻呼概率为[0.25-0.5)的终端设备分配至分组2,寻呼概率为[0.5-0.75)的终端设备分配至分组3,寻呼概率为[0.75-1]的终端设备分配至分组4。
基于寻呼概率对终端设备进行分组的另一种实现方式如下:寻呼概率由终端设备与核心网设备协商得到后,核心网设备在发送寻呼消息时,携带该终端设备的寻呼概率。接入网设备在发送唤醒信号时,携带基于该寻呼概率确定的终端设备的组标识。具体的,接入网设备在通过广播的方式发送该终端设备的分组方式,比如指示寻呼概率为[0.25-0.5)为组1,寻呼概率为[0.75-1]为组2。接入网设备再发送唤醒信息时携带该组标识,终端设备通过接收广播的该终端设备的组标识,确定自身所在的分组。进而,当终端设备接收唤醒信号后,该唤醒信号中的组标识与自身所在的分组一致,则终端设备被唤醒。
在另一种可能的实现方式中,唤醒信息中直接携带终端被寻呼的概率,匹配寻呼概率值的终端被唤醒,即接收寻呼消息或者直接发起接入。在另一种可能的实现方式中,寻呼概率还可以是终端设备在单位时间内被寻呼的次数。例如,将一个小时内被寻呼次数小于20次的终端设备分配至分组1,将一个小时内被寻呼次数小于50次且大于或等于20次的终端设备分配至分组2,一个小时内被寻呼次数大于50次的终端设备分配至分组3。
在另一种可能的实现方式中,该终端设备的组标识可以是位图(bitmap)的形式实现,例如:唤醒信息中的组标识为一串比特串,其中,该比特串的第一个比特位指示分组1,该比特串的第二个比特位指示分组2,以此类推。当比特位为1时,指示该分组的终端设备被唤醒;当比特位为0时,指示该分组的终端设备没有被唤醒。第一个比特表示分组1,第二个比特表示分组2,以此类推。
示例性的,该第一配置信息可以是注册接受消息,或者TAU更新接收消息,等其它NAS消息,此处不作限制。
703b、接入网设备向终端设备发送第一配置信息。
接入网设备接收来自核心网设备的第一配置信息后,向终端设备转发该第一配置信息。可选地,接入网设备不识别该第一配置信息,将该第一配置信息转发给终端设备。
704a、终端设备向接入网设备发送第二信息。
当终端设备与接入网设备的无线资源控制(Radio Resource Control,RRC)连接建立后,终端设备向接入网设备发送第二信息。该第二信息可以称为终端设备支持的能力信息。该第二信息指示以下一项或多项信息:
终端设备是否支持配置第一状态,或者终端设备接收来自接入网设备的唤醒信息后的处理时延,或者终端设备从接收来自接入网设备的唤醒信息后到接收来自接入网设备的寻呼消息的最小时间。
一种可能的实现方式中,终端设备包括低功耗收发电路,该低功耗收发电路用于接收唤醒信息。则上述终端设备接收来自接入网设备的唤醒信息后的处理时延指的是该低功耗收发电路接收该唤醒信息、处理该唤醒信息,以及向终端设备的主电路发送激活命令的时 间。
终端设备从接收来自接入网设备的唤醒信息后到接收来自接入网设备的寻呼消息的最小时间,指的是终端设备接收该唤醒信息后至接收寻呼消息之间,处理该唤醒信息最小需要的时间。
该第二信息还可以包括以下一项或多项信息:
终端设备是否支持接收唤醒信息,终端设备是否支持根据唤醒信息离开第一状态,终端设备中低功耗收发电路向终端设备的主电路发送激活命令需要的最小处理时间,终端设备是否支持按照组标识配置第一状态(即终端设备是否支持按照分组配置第一状态),或者,终端设备的寻呼概率范围,其中,该寻呼概率范围指示终端设备被寻呼的概率属于该范围区间。
示例性的,终端设备接收来自接入网设备的唤醒信息后的处理时延可以是20毫秒(ms),40ms,240ms,1000ms,或者2000ms。
该第二信息可以携带在终端设备能力信息(UECapabilityInformation)中。
终端设备可以向网络侧上报自身的能力信息(即第二信息),避免终端设备与网络侧之间因为不兼容的问题而导致终端设备无法进入第一状态。
704b、接入网设备向核心网设备转发第二信息。接入网设备接收来自终端设备的第二信息后,向核心网设备转发该第二信息。
705、接入网设备向终端设备发送第一信息。
接入网设备向终端设备发送第一信息,终端设备根据第一信息进入第一状态。
该第一信息可以指示某个终端设备进入第一状态,第一信息也可以指示某个组的终端设备进入第一状态。第一信息还可以指示重定向小区中的终端设备进入第一状态。第一信息还可以指示某一个或多个小区的终端设备进入第一状态。
可选地,该第一信息还可以包括寻呼概率,则该第一信息指示相同寻呼概率的终端设备进入第一状态。示例性的,当第一信息包括的寻呼概率为0.75,则接收到该第一信息的终端设备中寻呼概率为0.75的终端设备进入第一状态。又一种示例中,当第一信息包括的寻呼概率为(0.75-1],则接收到该第一信息的终端设备中寻呼概率在(0.75-1]区间内的终端设备进入第一状态。
可选地,第一信息可以携带在RRC释放消息中。
706、终端设备进入第一状态。
步骤706与前述步骤602类似,此处不作赘述。

707、核心网设备向接入网设备发送寻呼消息。
当核心网设备有下行数据时,该下行数据的目的地为处于第一状态的终端设备。核心网设备向接入网设备发送寻呼消息。
可选地,寻呼消息中包括第一指示信息,该第一指示信息指示接入网设备采用唤醒信 息指示终端设备离开第一状态。即寻呼消息中包括一个显式的指示信息,该显式的指示信息称为第一指示信息。接入网设备收到寻呼消息后,根据该第一指示信息向终端设备发送唤醒信息,该唤醒信息指示终端设备离开第一状态。
可选地,核心网设备向接入网设备发送的寻呼消息中包括唤醒信息的配置信息。该唤醒信息的配置信息包括以下一项或多项:终端设备的标识,组标识,是否基于终端设备的分组唤醒终端设备,唤醒信息的发送速率、DRX周期、或者扩展非连续接收eDRX周期。该唤醒信息的配置信息用于配置该接入网设备如何使用唤醒信息指示终端设备离开第一状态。
在另一种可能的实现方式中,核心网设备有下行数据时,核心网设备向接入网设备发送第一指示信息。此时,核心网设备通过第一指示信息指示接入网设备采用唤醒信息指示终端设备离开第一状态。即核心网设备不通过寻呼消息指示接入网设备采用唤醒信息指示终端设备离开第一状态。该寻呼消息与第一指示信息相互独立。
在另一种可能的实现方式中,接入网设备指示终端设备进入第一状态。第一状态可以为非激活状态的一个子集。核心网设备并不知道终端设备进入第一状态。当核心网设备向终端设备发送下行数据时,接入网设备接收该下行数据。接入网设备接收该下行数据后,接入网设备判断终端设备是否处于第一状态。若接入网设备判断终端设备处于第一状态,则接入网设备向终端设备发送唤醒信息,指示终端设备离开第一状态。
708、接入网设备向终端设备发送唤醒信息。

可选地,当接入网设备向终端设备发送唤醒信息后,终端设备可以向接入网设备发送反馈信息。该反馈信息可以包括唤醒信息的部分或全部信息。该反馈信息指示终端设备成功接收唤醒信息。
接入网设备收到来自终端设备的反馈信息后,接入网设备继续执行后续流程,例如:向终端设备发送寻呼消息或者向终端设备发送下行数据。当接入网设备向终端设备发送唤醒信息后,在一段时间内,接入网设备未收到来自终端设备的反馈信息,则接入网设备确认此次唤醒终端设备失败(即指示终端设备离开第一状态失败)。接入网设备提升该唤醒信息的功率后,向终端设备发送该提升功率的唤醒信息。或者,接入网设备重复发送该唤醒信息,例如:接入网设备重复5次发送该唤醒信息。或者,接入网设备降低调制与编码策略(Modulation and Coding Scheme,MCS)的调制阶数后,向终端设备发送该唤醒信息。
可选地,接入网设备可以根据终端设备上报的第二信息,确定在当前的PO中是否有充足的时间唤醒终端设备(即向终端设备发送唤醒信息,并指示终端设备离开第一状态)。若时间充足,则接入网设备在当前PO中重新发送唤醒信息。若时间不充足,则接入网设备在下一个PO或者其它PO中向终端设备发送该唤醒信息。
关于该唤醒信息,该唤醒信息可以包括终端设备的标识,和/或终端设备的组标识。该唤醒信息包括的终端设备的标识指示对应的终端设备离开第一状态。
可选地,该唤醒信息包括的终端设备的组标识指示对应的一组终端设备离开第一状态。
可选地,该唤醒信息包括的终端设备的组标识指示对应的一组终端设备可以离开第一 状态,该组终端设备中具体的某个终端设备是否离开第一状态还需要根据来自接入网设备的寻呼消息的指示。例如:当唤醒信息包括终端设备的组标识时,接收到该唤醒信息的终端设备首先判断自身是否属于该组标识对应的分组。若属于,则终端设备监听寻呼消息,当该寻呼消息包括该终端设备的标识,则终端设备发起接入网络流程;当该寻呼消息不包括该终端设备的标识,则终端设备继续保持第一状态。
709、终端设备离开第一状态。
终端设备可以根据多种条件离开第一状态,下面分别进行说明:
在第一状态中,当终端设备接收来自接入网设备的唤醒信息后,终端设备根据该唤醒信息离开第一状态。该指示终端设备离开第一状态的唤醒信息可以是某一类特殊的唤醒信息,例如唤醒指示。
在第一状态中,当终端设备的第一状态的计时器超时,且终端设备未接收到来自接入网设备的唤醒信息,终端设备离开第一状态。
在第一状态中,当终端设备在连续N次寻呼机会内(N个寻呼周期)未收到来自接入网设备的唤醒信息时,终端设备离开第一状态。
离开第一状态后,终端设备可以直接接入网络。例如:当唤醒信息包括该终端设备的标识时,终端设备根据该终端设备的标识直接接入网络。
离开第一状态后,终端设备也可以接收来自接入网设备的寻呼消息,并发起接入网络的流程。例如:当唤醒信息包括终端设备的组标识时,接收到该唤醒信息的终端设备首先判断自身是否属于该组标识对应的分组。若属于,则终端设备监听寻呼消息,当该寻呼消息包括该终端设备的标识,则终端设备发起接入网络流程;当该寻呼消息不包括该终端设备的标识,则终端设备继续保持第一状态。
本申请实施例中,通过引入低功耗的第一状态,节省了终端设备的功耗。通过多种方式可以唤醒处于第一状态的终端设备,以保证终端设备的业务正常运行。相较于现有的WUS技术,终端设备减少了监听PDCCH的时间,进一步降低终端设备的功耗。终端设备还可以通过低功耗收发电路监听唤醒信息,进一步降低终端设备的功耗。
