Description

系统信息传输方法、设备及系统
本申请要求于2020年04月14日提交国家知识产权局、申请号为202010291741.5、申请名称为“系统信息传输方法、设备及系统”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，尤其涉及系统信息传输方法、设备及系统。
背景技术
在移动通信网络中，网络对终端设备的寻呼通常分为两类，一类用于通知终端设备进行随机接入，使终端设备进入无线资源控制(radio resource control，RRC)连接态，以便后续进行数据通信；另一类用于通过短消息通知终端设备接收系统信息(system information，SI)。
目前，终端设备确定接收系统信息时，首先接收系统信息块(system information block，SIB)1，之后从SIB1中获取下行控制信息(downlink control information，DCI)的调度信息，再根据该DCI的调度信息获取DCI，最后根据该DCI接收系统信息。
然而，使用上述方案接收系统信息的时延较长，特别地，在终端设备接收SIB1失败时，需要等待下一个周期重新接收SIB1，直到SIB1接收成功后再根据DCI接收系统信息，进一步增加了系统信息的接收时延。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术或名词的简要介绍如下。
第一、无线资源控制(radio resource control，RRC)状态。
以新空口(new radio，NR)系统为例，在NR中，终端设备的RRC状态包括如下三种状态：RRC连接态(RRC_CONNECTED)、RRC去活动态(RRC_INACTIVE)和RRC空闲态(RRC_IDLE)，三种状态的转换如图1所示。
其中，当终端设备处于RRC连接态时，终端设备与接入网设备以及核心网设备都已经建立了连接，当有数据到达网络时可以直接传输到终端设备；当终端设备处于RRC去活动态时，终端设备和接入网设备以及核心网设备之间建立过链路，但是终端设备和接入网设备之间的链路被释放了，此时，终端设备和接入网设备保存有终端设备的上下文，当有数据需要传输时，接入网设备可以快速地恢复链路；当终端设备处于RRC空闲态时，终端设备与接入网设备以及核心网设备之间都没有建立过链路，当有数据需要传输时，需要先建立终端设备到接入网设备以及核心网设备的链路。
可以理解的是，上述RRC状态仅为一种举例，不应对本申请构成任何限定。本申请也并不排除在未来的协议中定义其他可能的命名来替代现有命名，但具有相同或相似的特性，或者也有可能出现其他的状态。
第二、网络对终端设备的寻呼。
在移动通信网络(例如长期演进(longterm evolution，LTE)或NR)中，网络对终端设备的寻呼通常分为两类，一类用于通过寻呼(Paging)消息通知处于RRC空闲态的终端设备进行随机接入，从而使得该终端设备进入RRC连接态，以便后续进行数据通信；另一类用于通过短消息通知终端设备接收系统信息。
由此，本申请实施例中，寻呼(Paging)消息指用于向处于RRC空闲态的终端设备发送呼叫请求，通知该终端设备进行随机接入的消息；短消息指用于通知终端设备接收系统信息的消息。
本申请实施例中，系统信息包括承载在SIB6、SIB7、或SIB8上的公共安全告警信息，或者包括承载在除SIB6、SIB7和SIB8之外的其他SIB上的信息。
可以理解的是，“接收系统信息”也可以理解为“接收承载该系统信息的SIB”，二者可以相互替换。
其中，公共安全告警信息包括地震海啸告警系统(earthquake and tsunami warning system，ETWS)信息和/或商业移动警示服务(commercial mobile alert service，CMAS)信息。ETWS包括承载在SIB6上的ETWS主(primary)信息和/或承载在SIB7上的ETWS辅(secondary)信息；CMAS通过SIB8承载。
第三、短消息和寻呼消息的调度。
现有的标准协议中，通过寻呼DCI(即paging DCI)指示该DCI中是否包括短消息，以及该DCI中是否包括寻呼消息的调度信息。
其中，该寻呼DCI中包括的部分字段如下：
短消息指示(short messages indicator)字段：大小为2比特(bit)，内容定义见下表1。其中，状态“00”预留，不使用，即短消息指示为“00”时，该状态无效。
表1
bitfield 短消息指示
00 预留，不使用
01 DCI包括寻呼消息的调度信息，且该DCI不包括短消息。
10 DCI不包括寻呼消息的调度信息，且该DCI包括短消息。
11 DCI包括寻呼消息的调度信息，且该DCI还包括短消息。
短消息内容(short message)字段：大小为8bits，内容定义见下表2。如果上述短消息指示字段指示该DCI中包括寻呼消息的调度信息，不包括短消息，则该字段无效(reserved)。
需要说明的是，本申请实施例中，字段无效指该字段/状态不承载信息，或者终端设备或网络设备不解析该字段，在此统一说明，下述实施例不再赘述。
表2
Figure PCTCN2021086032-appb-000001
其中，BCCH表示广播控制信道(broadcast control channel，BCCH)。
该短消息内容字段的第1个比特的取值为“1”时，指示承载在BCCH的系统信息有修改，也可以理解为：指示除SIB6、SIB7和SIB8之外的其他SIB有更新，但是该比特不能指示更新的SIB具体为哪些SIB；该短消息内容字段的第2个比特的取值为“1”时，指示有ETWS和/或CMAS信息，也可以理解为：指示SIB6、SIB7和SIB8中的一项或多项有更新，同样，该比特不能指示SIB6、SIB7、SIB8中更新的SIB具体为哪些SIB。
频域资源指示字段：大小根据频域资源最大数确定，例如，其大小可以满足公式：
Figure PCTCN2021086032-appb-000002
其中，
Figure PCTCN2021086032-appb-000003
为频域最大资源数，或为可分配的频域资源数。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息，则该字段无效。
时域资源指示字段：大小为4bits。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息，则该字段无效。
调制编码方案指示字段：大小为5bits。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息，则该字段无效。
传输块缩放因子字段：大小为2bits。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息，则该字段无效。
预留比特：大小为6bits。
第四、寻呼时机。
终端设备可以周期地接收上述寻呼DCI，该周期即为寻呼周期。终端设备具体接收该DCI的时刻称为寻呼时机(paging occasion，PO)，由网络设备确定并向终端设备配置。
示例性的，如图2所示，一个寻呼周期内，可以包括多个寻呼帧(paging frame，PF)，每个寻呼帧包括多个PO，其中，一个PO对应一个或多个终端设备，即在一个PO中传输的寻呼DCI所调度的寻呼消息中可以承载多个终端设备的寻呼信息。
第五、现有公共安全告警信息的接收流程。
如图3a所示，现有协议规定的公共安全告警信息的接收流程可以包括如下步骤：
S301、终端设备接收寻呼DCI。
其中，终端设备可以根据网络设备的配置确定PO，并在该PO上检测物理下行控制信道(physical downlink control channel，PDCCH)，当检测到PDCCH时，解析该PDDCH上承载的寻呼DCI。
终端设备可以确定该DCI中的短消息指示字段是否指示该寻呼DCI包括短消息，当确定该寻呼DCI中包括短消息(例如，该短消息指示字段的值为“10”或“11”)时，再确定该寻呼DCI中的短消息内容字段是否指示有ETWS和/或CMAS信息，当确定该短消息指示有ETWS和/或CMAS信息(例如，该短消息内容字段的第2个比特的值为“1”)时，执行下述步骤S302。
S302、终端设备获取系统信息调度信息(SI scheduling information，SI-SchedulingInfo)。
其中，终端设备可以接收来自网络设备的SIB1，再从SIB1中获取该SI-SchedulingInfo，并执行下述步骤S303。
该SI-SchedulingInfo中包括的部分元素如下：
调度信息列表(schedulingInfoList)：定义一个或多个DCI的调度信息，该一个或多个DCI中的每个DCI调度一个系统消息(SI-message)，每个系统消息可以包括1个或多个SIB。即调度信息列表中包括一个或多个DCI的调度信息(SchedulingInfo)。
系统信息窗长(si-WindowLength)：定义系统消息检测窗长，其取值例如可以为{s5，s10，s20，s40，s80，s160，s320，s640，s1280}中的一个，s代表子帧，时间单位可以为1毫秒，例如s5表示5毫秒。
DCI的调度信息中包括的部分信元如下：
si-BroadcastStatus：表示系统消息是否为广播消息；
si-Periodicity：表示调度系统消息的DCI的广播周期，取值例如可以为{rf8，rf16，rf32，rf64，rf128，rf256，rf512}中的一个，rf代表无线帧，时间单位可以为10毫秒，例如rf8表示80ms；
sib-MappingInfo：表示该DCI调度的系统消息中包括的SIB。
示例性的，以共广播7个SIB，分别为SIB2、SIB3、SIB4、SIB5、SIB6和SIB7 为例，则该SI-SchedulingInfo可以如下：
Figure PCTCN2021086032-appb-000004
相应的，在该情况下，DCI1和DCI2的检测示意图可以如图3b所示，终端设备可以根据该SI-SchedulingInfo在每个周期的时间窗1内检测DCI1，在时间窗2内检测DCI2。
S303、终端设备根据SI-SchedulingInfo，接收调度公共安全告警信息的DCI。
即终端设备根据SI-SchedulingInfo中的配置信息，接收DCI。
S304、终端设备根据调度公共安全告警信息的DCI，接收公共安全告警信息。
例如，终端设备在该DCI调度的时频资源上接收公共安全告警信息。
至此，公共安全告警信息的接收流程结束。除SIB6、SIB7和SIB8之外的SIB的接收流程与图3a所示的流程类似，在此不予赘述。
第六、寻呼消息的结构。
以NR系统为例，寻呼消息中可以包括寻呼记录列表(pagingRecordList)，在该pagingRecordList中可以包括一个或多个寻呼记录(pagingRecord)，每个pagingRecord中可以包括终端设备标识(ue-Identity)信元和接入类型(accessType)信元。
示例性的，pagingRecord的结构可以如下所示：
Figure PCTCN2021086032-appb-000005
其中，“...”表示pagingRecord可扩展，即pagingRecord中除ue-Identity和accessType外，还可以包括其他信元。
示例性的，ue-Identity的结构可以如下所示：
Figure PCTCN2021086032-appb-000006
Figure PCTCN2021086032-appb-000007
其中，TMSI表示临时移动用户识别码(temporary mobile subscriber identity)，I表示RRC去活动态(RRC_INACTIVE)，RNTI表示无线网络临时标识(radio network temporary identifier)。“...”表示ue-Identity可扩展，即ue-Identity中除ng-5G-S-TMSI和fullI-RNTI外，还可以包括其他信元。
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。其中，在本申请的描述中，除非另有说明，“/”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；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，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。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，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。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。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“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。确切而言，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。
本申请实施例的技术方案可以应用于各种通信系统。例如该通信系统可以为长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)通信系统、NR系统、无线保真(wireless-fidelity，WiFi)系统，第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的通信系统以及未来演进的通信系统等，不予限制。术语“系统”可以和“网络”相互替换。5G通信系统是正在研究当中的下一代通信系统。其中，5G通信系统包括非独立组网(non-standalone，NSA)的5G移动通信系统，独立组网(standalone，SA)的5G移动通信系统。此外，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。上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，在此统一说明，以下不再赘述。
此外，本申请实施例描述的网络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。
本申请提供的技术方案适用于通信装置，例如网络设备和终端设备，为了表述方便，以下是以网络设备和终端设备为例进行说明，并不限定所述方案的执行主体。
如图4所示，为本申请实施例提供的一种通信系统10。该通信系统10包括至少一个网络设备30，以及与该网络设备30连接的一个或多个终端设备40。可选的，不同的终端设备40之间可以相互通信。
以图4所示的网络设备30与任一终端设备40通信为例，本申请实施例中，网络设备30向终端设备40发送第一信息和第一系统信息，该第一信息包括第一指示信息，该第一指示信息指示终端设备接收第一系统信息，相应的，终端设备40接收第一信息后，基于第一指示信息根据第二信息或第三信息或第四信息接收第一系统信息。其中，第二信息为第一信息包括的信息，第二信息包括用于第一系统信息传输的配置信息；第三信息为终端设备在接收第一信息之前获得的用于第一系统信息传输的配置信息；第四信息为第一信息调度的信息，第四信息包括用于第一系统信息传输的配置信息。
基于该方案，由于第一指示信息指示终端设备接收第一系统信息时，在该第一指示信息所属的第一信息中包括用于第一系统信息传输的配置信息，或者使用该第一信息调度包括用于第一系统信息传输的配置信息的信息，因此终端设备在确定接收第一系统信息时，可以直接根据该第一信息接收第一系统信息，或者可以根据之前获得的用于第一系统信息传输的配置信息接收第一系统信息，从而无需接收SIB1，再根据SIB1接收第一系统信息，进而降低第一系统信息的接收时延。
可选的，本申请实施例中的网络设备30是一种具有收发功能的设备，包括但不限于：LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，NR中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point，TRP)，3GPP后续演进的基站，WiFi系统中的接入节点，无线中继节点，无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，中继站，或，气球站，卫星站等。多个基站可以支持上述提及的同一种技术的网络，也可以支持上述提及的不同技术的网络。基站可以包含一个或多个共站或非共站的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)，和/或，分布单元(distributed unit，DU)。网络设备还可以是服务器，可穿戴设备，机器通信设备、或车载设备等。以下以网络设备为基站为例进行说明。基站可以与终端进行通信，也可以通过中继站与终端进行通信。终端可以与不同技术的多个基站进行通信，例如，终端可以与支持LTE网络的基站通信，也可以与支持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。

可选的，CU可以由CU控制面(CU control plane，CU-CP)和CU用户面(CU user plane，CU-UP)组成，CU-CP和CU-UP可以理解为是对CU从逻辑功能的角度进行划分。其中，CU-CP和CU-UP可以根据无线网络的协议层划分，例如，RRC协议层和信令无线承载(signal radio bearer，SRB)对应的PDCP协议层的功能设置在CU-CP中，数据无线承载(data radio bearer，DRB)对应的PDCP协议层的功能设置在CU-UP中。此外，SDAP协议层的功能也可能设置在CU-UP中。

目前，在现有的系统信息接收流程中，终端设备在接收系统信息之前，需要接收SIB1以获取SI-SchedulingInfo，之后根据SI-SchedulingInfo接收系统信息的调度信息，再根据系统信息的调度信息接收系统信息，该流程增加了系统信息的接收时延。特别 地，如图7所示，当SIB1接收失败时，需要等待下一个周期重新接收SIB1，直到SIB1接收成功后再根据调度信息接收系统信息，进一步增加了系统信息的接收时延。

下面对本申请实施例中的第二信息、第三信息、以及第四信息进行展开说明。
对于第二信息：
可选的，在本申请实施例的不同实施场景下，第二信息包括的用于第一系统信息传输的配置信息也可能不同。
一种可能的实现方式中，第二信息包括的用于第一系统信息传输的配置信息为第一调度信息，第一调度信息为第一系统信息的调度信息。即第二信息包括第一系统信息的调度信息，该第一系统信息的调度信息调度时域资源和/或频域资源，第一系统信息在该时域资源和/或频域资源中传输。
也就是说，在该实现方式中，本申请实施例的终端设备的处理流程可以如图8c所 示：
S801、终端设备接收第一信息。
S803、根据类型指示信息和/或范围指示信息，确定接收第一系统信息。
其中，步骤S803为可选执行的步骤，步骤S801和步骤S803可参考图8a或图8b所示的实施例中的相关说明。

可选的，当第一信息包括的短消息指示信息的比特状态为第一状态，或短消息指示信息指示第一信息不包括寻呼消息的调度信息时，上述一项或多项信息可以复用第一信息中原本为寻呼消息的调度设计的字段。基于该方案，由于可以复用原本为寻呼消息的调度设计的字段，从而可以不改变现有DCI的格式，更好地实现后向兼容。
基于该可能的实现方式，由于在第一信息中承载第一系统信息的调度信息，因此可以使得终端设备直接根据该调度信息接收第一系统信息，无需接收SIB1，再根据SIB1接收第一系统信息，从而可以降低第一系统信息的接收时延。

其中，传输周期信息指示第一调度信息的传输周期，其时间单位例如可以为无线帧，即第一调度信息的传输周期可以为r个无线帧，r为正整数。时间窗的长度表示在第一调度信息的传输周期中检测第一调度信息时的时间范围，其时间单位例如可以为子帧，即时间窗的长度可以为s个子帧，s为正整数；时间窗的标识指示承载第一调度信息的时间窗。时域资源指示信息指示第一调度信息传输的起始时域资源位置、时域长度等。起始时域资源位置可以为第一调度信息开始传输的时隙、符号、子帧、帧、迷你时隙、子时隙等。
可以理解的是，上述时间窗的长度或周期的时间单位也可以是时隙、符号、子帧、迷你时隙、子时隙等，本申请实施例对此不做具体限定。
可选的，在该实现方式中，第一信息包括的短消息指示信息指示的内容不同，上述一项或多项信息在第一信息中所占用的字段也不同。示例性的，可能存在以下两种情况：
情况一、短消息指示信息指示第一信息包括短消息，且第一信息不包括寻呼消息的调度信息。
在该情况下，传输周期信息、时间窗指示信息、时域资源指示信息中的一项或多项可以复用第一信息中原本为寻呼消息的调度信息设计的字段，原本为寻呼消息的调度信息设计的字段可以包括频域资源指示字段、时域资源指示字段、调制编码方案指示字段、传输块缩放因子字段、或者预留比特中的一个或多个。或者说，在该情况下，第一信息中不包括为寻呼消息的调度信息设计的字段，包括指示用于第一系统信息传输的配置信息的字段。
在该用于第一系统信息传输的配置信息可以包括传输周期信息和/或时间窗指示信息时，第一信息可以包括周期字段、窗长字段、以及标识字段，用以分别指示传输 周期信息、时间窗的长度、以及时间窗的标识。
可选的，若周期字段、窗长字段、以及标识字段的大小均为3比特，示例性的，周期字段的内容定义可以如下表5所示，窗长字段的内容定义可以如下表6所示，标识字段的内容定义可以如下表7所示。

可以理解的是，该用于第一系统信息传输的配置信息包括其他信息时，例如时域资源指示信息时，第一信息中也可以相应的包括时域资源指示字段，具体实现可参见上述周期字段、窗长字段、以及标识字段的相关描述，在此不再赘述。
基于该可能的实现方式，由于在第一信息中承载第一调度信息的时域位置信息，在第一系统信息的调度信息过大而无法由第一信息承载的情况下，可以使得终端设备根据第一调度信息的时域位置信息逐步接收第一系统信息，从而降低第一系统信息的接收时延。
对于第三信息：
可选的，本申请实施例中，第三信息可以为第一调度信息，也可以为用于配置第一调度信息的时域位置的信息。其中，第一调度信息和用于配置第一调度信息的时域位置的信息可参考上述第二信息中的相关说明，在此不再赘述。
可选的，该第三信息可以是终端设备存储的上一次接收第一系统信息时使用的用于第一系统信息传输的配置信息；也可以是网络设备在发送第一信息前，向终端设备发送的用于第一系统信息本次传输的配置信息。
对于第四信息：
可选的，本申请实施例中，第一信息调度的第四信息可以为寻呼消息包括的信息，即第一信息包括寻呼消息的调度信息，该寻呼消息的调度信息调度的寻呼消息中包括第四信息，第四信息包括用于第一系统信息传输的配置信息。在该情况下，可以理解为第一信息包括的短消息指示信息指示第一信息包括寻呼消息的调度信息，也包括短消息。
可选的，在本申请实施例的不同实施场景下，第四信息包括的用于第一系统信息传输的配置信息也可能不同。
一种可能的实现方式中，第四信息包括的用于第一系统信息传输的配置信息为第一调度信息，第一调度信息为第一系统信息的调度信息。即第四信息包括第一系统信息的调度信息，该第一系统信息的调度信息调度时域资源和/或频域资源，第一系统信息在该时域资源和/或频域资源中传输。
也就是说，在该实现方式中，本申请实施例的终端设备的处理流程可以如图8e所示：
S801、终端设备接收第一信息。
S803、根据类型指示信息和/或范围指示信息，确定接收第一系统信息。
其中，步骤S803为可选执行的步骤，步骤S801和步骤S803可参考图8a或图8b所示的实施例中的相关说明。
其中，步骤S802可以包括如下步骤：
S8021c、终端设备根据第一信息获取第四信息。
可选的，终端设备接收第一信息后，可以根据第一信息包括的寻呼消息的调度信息，接收寻呼消息，再解析该寻呼消息，获取该寻呼消息中的第四信息。
S8022c、终端设备根据第四信息获取第一调度信息。
可选的，终端设备获取第四信息后，可以根据第一调度信息在第四信息中的位置，获取第四信息包括的第一调度信息。
S8023c、终端设备根据第一调度信息接收第一系统信息。
可选的，终端设备根据第一调度信息接收第一系统信息可以包括：终端设备在第一调度信息所调度的时域资源和/或频域资源上接收第一系统信息。
可选的，在该实现方式中，该用于第一系统信息传输的配置信息可以包括以下一项或多项：频域资源指示信息、时域资源指示信息、调制编码方式指示信息、传输块缩放因子信息、波束信息、功率信息、子载波间隔信息。
可选的，在该情况下，第四信息包括第一调度信息可以为：第四信息包括第一字段，该第一字段包括第一调度信息。示例性的，第四信息中可以包括特定结构体(例如pagingRecord)，该特定结构体中可以包括第一字段，并在该第一字段中包括第一调度信息。
可选的，第一字段可能存在如下两种情况：
情况一、该第一字段可以是终端设备标识字段。
当该结构体为pagingRecord时，即复用现有的终端设备标识字段传输第一调度信息。可以理解的是，此时该终端设备标识字段不用于指示系统中的某个终端设备。
在该实现方式中，可选的，若第一调度信息未占用终端设备标识字段的全部比特，该终端设备标识字段中还可以包括第三指示信息，该第三指示信息用于指示第一调度信息在终端设备标识字段中的位置，例如，该第三指示信息指示第一调度信息在该终端设备标识字段中的起始比特位置和/或第一调度信息的长度，或者，该第三指示信息指示第一调度信息位于该终端设备标识字段的高比特位或低比特位。
基于该方案，由于可以通过第三指示信息指示第一调度信息在终端设备标识字段中的位置，可以使得终端设备正确解析该终端设备标识字段，避免将该字段解析为某个终端设备的标识，导致该标识对应的终端设备将该字段所在的结构体中的信息解析为该终端设备的寻呼信息。
情况二、当该特定结构体为pagingRecord时，该第一字段可以为该特定结构体中除终端设备标识字段和接入类型字段之外的扩展字段。
此时，为了区分第一调度信息与寻呼信息，该特定结构体的终端设备标识字段指示的终端设备为系统中不存在的终端设备。
可以理解的是，在该实现方式中，第一字段还可以有其他名称，本申请实施例对此不做具体限定。示例性的，以该特定结构体为pagingRecord，第一字段的名称为SchedulingInfo为例，则该特定结构体的结构可以如下所示：
Figure PCTCN2021086032-appb-000008
可选的，在该情况下，第四信息还可以包括第四指示信息，该第四指示信息用于指示第四信息中包括第一调度信息。基于该方案，可以指示终端设备根据第四信息中的第一调度信息接收第一系统信息，而无需按照现有的流程接收SIB1后，再根据SIB1接收公共安全告警信息。
基于该可能的实现方式，由于在第一信息调度的寻呼消息包括的第四信息中包括第一调度信息，使得第一信息可以调度寻呼消息，并在寻呼消息中传输第一系统信息的调度信息，从而终端设备可以根据寻呼消息中的第一调度信息接收第一系统信息，进而降低第一系统信息的接收时延。
另一种可能的实现方式中，第四信息包括的用于第一系统信息传输的配置信息，用于配置第一调度信息的时域位置。
也就是说，终端设备可以根据用于第一系统信息传输的配置信息，接收第一调度信息，并根据第一调度信息接收第一系统信息，即在第一调度信息调度的时域资源和/或频域资源上接收第一系统信息。即在该实现方式中，本申请实施例的终端设备的处理流程可以如图8f所示：
S801、终端设备接收第一信息。
S803、根据类型指示信息和/或范围指示信息，确定接收第一系统信息。
其中，步骤S803为可选执行的步骤，步骤S801和步骤S803可参考图8a或图8b所示的实施例中的相关说明。
其中，步骤S802可以包括如下步骤：
S8021d、终端设备根据第一信息获取第四信息。
S8022d、终端设备根据第四信息获取第一调度信息的时域位置信息。
可选的，终端设备获取第四信息后，可以根据第一调度信息的时域位置信息在第四信息中的位置，获取第四信息包括的第一调度信息的时域位置信息。
S8023d、终端设备根据第一调度信息的时域位置信息获取第一调度信息。
可选的，终端设备根据第一调度信息的时域位置信息获取第一调度信息，可以包括：终端设备在第一调度信息的时域位置信息所指示的时域位置上接收第一调度信息。
S8024d、终端设备根据第一调度信息接收第一系统信息。
可选的，终端设备根据第一调度信息接收第一系统信息可以包括：终端设备在第一调度信息所调度的时域资源和/或频域资源上接收第一系统信息。
可选的，该用于第一系统信息传输的配置信息可以包括以下一项或多项：传输周期信息、时间窗指示信息、或时域资源指示信息，该时间窗指示信息可以指示时间窗的长度和/或时间窗的标识。
可选的，在该情况下，第四信息包括用于第一系统信息传输的配置信息的方式可以参见上一种可能的实现方式中的第四信息包括第一调度信息的方式，在此不再赘述。
可选的，在本申请实施例的一种实施场景下，第一信息调度的第四信息可以包括第一系统信息，即第一信息包括寻呼消息的调度信息，该寻呼消息的调度信息调度的寻呼消息中包括第四信息，第四信息包括第一系统信息。在该情况下，可以理解为第一信息包括的短消息指示信息指示第一信息包括寻呼消息的调度信息，也包括短消息。
可选的，在该场景下，可以在第四信息中包括特定的结构体(例如pagingRecord)，在该特定的结构体中包括第一系统信息。
可选的，在该场景下，第四信息还可以包括第五指示信息，该第五指示信息用于指示该寻呼消息中包括第一系统信息。基于该方案，可以指示终端设备在寻呼消息中接收第一系统信息，而无需按照现有的流程接收SIB1后，再根据SIB1接收第一系统信息。
可选的，在该场景下，第一信息还可以包括第六指示信息，该第六指示信息用于指示第一系统信息在寻呼消息中的位置。基于该方案，可以使得终端设备根据该第六指示信息快速接收寻呼消息中的第一系统信息，无需遍历该寻呼消息中的各个结构体，进一步减少第一系统信息的接收时延。示例性的，该第六指示信息例如可以为第一系统信息所在的结构体(例如pagingRecord)在寻呼消息中的标识。
基于该可能的实现方式，由于在寻呼消息中承载第一调度信息的时域位置信息，在第一系统信息的调度信息过大而无法由寻呼消息承载的情况下，可以使得终端设备根据寻呼消息包括的第一调度信息的时域位置信息逐步接收第一系统信息，从而降低第一系统信息的接收时延。
综上，本申请实施例可以提供六种接收第一系统信息的方式，该六种方式可以组 成第一系统信息的接收方式集合：
方式一、根据第二信息包括的第一调度信息接收第一系统信息；
方式二、根据第二信息包括的用于配置第一调度信息的时域位置的信息接收第一系统信息；
方式三、根据第四信息包括的第一调度信息接收第一系统信息；
方式四、根据第四信息包括的用于配置第一调度信息的时域位置的信息接收第一系统信息；
方式五、根据终端设备在接收第一信息前获取的第三信息接收第一系统信息；
方式六、根据SIB1接收第一系统信息。
可选的，在该场景下，上述步骤S801中第一指示信息的比特状态为第一状态时，可以指示终端设备采用第一方式接收第一系统信息，相应的，步骤S802中，终端设备采用第一方式接收第一系统信息；第一指示信息的比特状态为第二状态时，可以指示终端设备采用第二方式接收第一系统信息，相应的，步骤S802中，终端设备采用第二方式接收第一系统信息。
可选的，第二指示信息的比特为第一状态时，可以指示终端设备采用第一方式接收第一系统信息，相应的，步骤S802中，终端设备采用第一方式接收第一系统信息；第二指示信息的比特状态为第二状态时，可以指示终端设备采用第二方式接收第一系统信息，相应的，步骤S802中，终端设备采用第二方式接收第一系统信息。
其中，第一方式为上述六种方式中的一种方式，第二方式为上述六种方式中与第一方式不同的方式。
本申请实施例还提供一种系统信息传输方法，该方法包括：
步骤1、网络设备向终端设备发送第一信息，相应的，终端设备接收来自网络设备的第一信息。
可选的，终端设备可以根据第一信息确定接收第一系统信息。
步骤2、网络设备向终端设备发送第一系统信息。相应的，终端设备接收来自网络设备的第一系统信息。
可选的，第一信息包括第一指示信息。
一种可能的实现方式中，第一指示信息能用于指示终端设备接收SIB1、终端设备无需接收SIB1中的一种或多种。例如，第一指示信息的比特状态为第一状态时，指示终端设备接收SIB1时，相应的，终端设备可以基于第一指示信息的指示接收SIB1，再根据SIB1接收第一系统信息；第一指示信息的比特状态为第二状态时，指示终端设备无需接收SIB1，相应的，终端设备根据上述第三信息接收第一系统信息。
可选的，指示终端设备接收SIB1，也可以理解为：指示终端设备监测承载SIB1的物理下行控制信道(physical down link control channel，PDCCH)；指示终端设备无需接收SIB1，也可以理解为：指示终端设备无需监测(monitor)承载SIB1的PDCCH。即第一指示信息能用于指示终端设备监测承载SIB1的PDCCH、终端设备无需监测承载SIB1的PDCCH中的一种或多种。
基于该方案，终端设备可以根据第一指示信息确定是否需要接收SIB1或监测承载SIB1的调度信息，可以降低终端设备接收SIB1的频度，从而节省终端设备的功耗开 销，在无需接收SIB1时降低终端设备接收第一系统信息的时延。
另一种可能的实现方式中，第一指示信息能用于指示第一信息包括第一系统信息传输相关的配置信息、第一信息不包括第一系统信息传输相关的配置信息中的一种或多种。例如，第一指示信息的比特状态为第一状态时，指示第一信息包括第一系统信息传输相关的配置信息，相应的，终端设备根据上述第二信息或第四信息接收第一系统信息；第一指示信息的比特状态为第二状态时，指示第一信息不包括第一系统信息传输相关的配置信息，相应的，终端设备根据上述第三信息接收第一系统信息。
又一种可能的实现方式中，第一指示信息能用于指示用于第一系统信息传输的配置信息有更新、用于第一系统信息传输的配置信息未更新中的一种或多种。例如，第一指示信息的比特状态为第一状态时，指示用于第一系统信息传输的配置信息有更新，相应的，终端设备根据上述第二信息或第四信息接收第一系统信息；第一指示信息的比特状态为第二状态时，指示用于第一系统信息传输的配置信息未更新，相应的，终端设备根据上述第三信息接收第一系统信息。
再一种可能的实现方式中，第一指示信息能用于指示终端设备接收SIB1、第一信息包括第一系统信息传输相关的配置信息、第一系统信息传输的配置信息未更新中的一种或多种。例如，第一指示信息的比特状态为第一状态时，指示用于第一系统信息传输的配置信息在SIB1中更新，相应的，终端设备接收SIB1，再根据SIB1接收第一系统信息；第一指示信息的比特状态为第二状态时，指示用于第一系统信息传输的配置信息在第一信息包括的第二信息中更新，或在第一信息调度的第四信息中更新，相应的，终端设备根据上述第二信息或第四信息接收第一系统信息；第一指示信息的比特状态为第三状态时，指示用于第一系统信息传输的配置信息未更新，相应的，终端设备根据上述第三信息接收第一系统信息。
基于该方案，终端设备可以根据第一指示信息确定根据第二信息或第三信息或第四信息接收第一系统信息，可以降低终端设备接收第一系统信息的时延。
