Description

一种寻呼方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种寻呼方法及装置。
背景技术
终端设备在特定时间段内唤醒接收寻呼(paging)下行控制信息(downlink control information，DCI)，paging DCI用于通知终端设备获取更新的系统信息或指示存在终端设备的寻呼调度信息。终端设备解析paging DCI，然后根据paging DCI的指示，终端设备获取更新的系统信息或者去paging DCI指示的物理下行共享信道(physical downlink shared channel，PDSCH)资源上读取paging消息内容等。
现有技术中对于不同类型的终端设备，采用相同的寻呼配置信息，但是不同类型的终端设备的能力不同，如不同类型的终端设备寻呼概率不同，就会导致寻呼概率较低的终端设备被频繁唤醒导致高能耗，又如不同类型的终端设备所需的系统信息不同，终端设备需要读取系统信息块类型1(System information block type 1，SIB1)中特定字段才能确定更新的系统信息是否为自身所需要，对于需要系统信息较少的终端设备来说，这些终端设备就需要频繁读取SIB1来判断自身所需要的系统信息是否发生了更新，因此频繁读取也会导致高能耗的问题。综上，对于不同类型的终端设备采用相同的寻呼配置信息，可能会导致高能耗的问题出现。

本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中。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设备为例，描述本申请实施例提供的技术方案。
另外，在本申请实施例中，终端设备还分为不同类型的终端设备，例如包括第一类型终端设备和第二类型终端设备。其中第一类型终端设备和第二类型终端设备的能力可以不同，如第一类型终端设备和第二类型终端设备的能力不同体现为以下的一种或多种：最大传输带宽、传输速率、可靠性、时延容忍度、天线数量、续航时间、终端尺寸、终端的硬件能力或终端的成本复杂度等。示例性的，在本申请实施例中第一类型终端设备可以为非降低性能UE(如NR legacy UE)，第二类型终端设备可以为降低性能UE(reduced capability UE)，降低性能UE也可以称为NR-light UE。或者，第一类型终端设备和第二类型终端设备可以分别为两种不同的降低性能UE(reduced capability UE)。可以理解的是，终端设备还可以包括第三类型终端设备，第四网络类型终端设备等等，更多类型的终端设备也可以采用本申请实施例提供的思想实现寻呼过程。

RRC连接态(或，也可以简称为连接态。在本文中，“连接态”和“RRC连接态”，是同一概念，两种称呼可以互换)：终端设备与网络建立了RRC连接，可以进行数据传输。
RRC空闲态(或，也可以简称为空闲态。在本文中，“空闲态”和“RRC空闲态”，是同一概念，两种称呼可以互换)：终端设备没有与网络建立RRC连接，基站没有存储该终端设备的上下文。如果终端设备需要从RRC空闲态进入RRC连接态，则需要发起RRC连接建立过程。
RRC非激活态(或，也可以简称为非激活态。在本文中，“去活动态”、“去激活态”、“非激活态”、“RRC非激活态”和“RRC去激活态”，是同一概念，这几种称呼可以互换)：终端设备之前进入了RRC连接态，然后基站释放了RRC连接，但是基站保存了该终端设备的上下文。如果该终端设备需要从RRC非激活态再次进入RRC连接态，则需要发起RRC连接恢复过程(或者称为RRC连接重建立过程)。RRC恢复过程相对于RRC建立过程来说，时延更短，信令开销更小。但是基站需要保存终端设备的上下文，会占用基站的存储开销。

为便于理解本申请实施例，接下来对本请的应用场景进行介绍。
先简单对寻呼(paging)进行介绍：长期演进(long term evolution，LTE)或NR中，paging用于向处于空闲(IDLE)态或未激活(INACTIVE)态的终端设备发送呼叫请求。
在NR系统中，基站对于处于RRC空闲态、休眠态、或RRC非激活态的终端设备，可以发送寻呼消息(paging消息)，以对这些终端设备发起寻呼并进行数据传输。通常，当基站需要寻呼终端设备时，将在一个或多个PO中发送paging DCI，指示承载寻呼消息的资源，该paging DCI承载于通过寻呼用的无线网络临时标识(paging-radio network temporary identity，P-RNTI)加扰的物理下行控制信道(physical downlink control channel，PDCCH)。其中，PO是由周期性的寻呼搜索空间(Search Space)和控制资源集(control resource set，CORESET)构成的。paging DCI为DCI format 1_0。
终端设备将在一个寻呼周期中的一个或多个PO中接收/检测/侦听paging DCI。paging DCI指示终端设备读取物理下行共享信道(physical downlink shared channel，PDSCH)资源上的paging消息内容。终端设备可以在paging DCI指示的PDSCH资源上读取paging消息内容，从而接收到寻呼消息，并判断基站是否对自己发起了寻呼。其中，终端设备需要检测的PO是根据终端设备的ID经过预定义的规则计算确定的。
例如，终端设备在一个非连续接收(discontinuous reception，DRX)周期中所检测的PO所在的寻呼帧(paging frame，PF)的系统帧号(system frame number，SFN)，以及该SFN对应的PF内的PO的索引等，可以通过下面的公式确定：
PF的SFN满足：
Figure PCTCN2020074648-appb-000001
在该SFN中的PO的索引i s满足：
Figure PCTCN2020074648-appb-000002
在如上公式中，SFN表示寻呼帧的系统帧号，PF_offset表示PF的偏移量，T表示DRX周期，N表示一个DRX周期内包括的PF的总数量，N s表示一个PF中包含的PO数，mod表示取模运算，UE_ID表示根据终端设备的ID得到的量，floor(x)表示对x向下取整。其中，PF offset、T、N、N s等均是基站配置的，而UE_ID则是根据终端设备的ID决定的。例如，UE_ID可以是终端设备的5G短临时移动用户标识(5G-short-temporary mobile subscriber identity，5G-S-TMSI)的后10位。一个PF可能包含一个或多个PO。
在LTE系统中，PDCCH在频域上占据整个频段，网络设备通过通知终端设备PDCCH占据的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号数，终端设备就能够确定PDCCH的Search Space。在NR系统中，网络设备将PDCCH在频域上占据的频段和PDCCH在时域上占据的OFDM符号数等信息封装在CORESET中，将PDCCH起始OFDM符号编号以及PDCCH监测周期等信息封装在Search Space中，终端设备能够CORESET和Search Space确定PDCCH对应的频域资源和时域资源，从而成功解码PDCCH。在NR系统中系统的带宽较大，这样，如果PDCCH不会占据整个带宽，能够节约浪费资源，避免盲检复杂度过大。
Paging DCI可以用于指示终端设备获取更新的系统信息(System Information，SI)。终端设备根据paging DCI的指示，可以将终端设备需要的且发生改变的系统信息进行更新。当网络设备修改了某些系统信息时，网络设备会先在一个变更周期内通知终端设备系统信息将发生变化，但不发送更新后的系统信息。然后网络设备在相邻的下一个变更周期，发送更新后的系统信息，终端设备在该变更周期内获取到发生改变的系统信息。如图2所示，不同的块代表不同的系统信息，例如填充有竖条纹的块为系统信息1，未填充条纹的块为 系统信息2，填充横条纹的块为系统信息3，在系统变更周期n中，终端设备接收到的系统变更指示，但是此时的系统信息仍然是更新前的系统信息即为系统信息1，终端设备会从下一个系统变更周期(即系统变更周期n+1)开始接收新的系统信息，在接下来的系统变更周期n+1中，网络设备广播新的系统信息如系统信息3，系统信息2在该过程中没有发生变化。对于同一服务小区里的不同终端设备来说，不同终端设备对应的寻呼时刻并不相同。为了保证所有的终端设备能够同时读取到更新后的系统信息，所有的终端设备从统一的指定时刻读取系统信息，即从下一变更周期的开始去接收新的系统信息，终端设备在接收到更新的系统信息之前，会一直使用更新前的旧的系统信息。
在NR系统中，网络设备通知终端设备系统信息发生变化采用以下两种方式。方式1中，网络设备可以通过Short Message来通知处于RRC_IDLE态、RRC_INACTIVE态和RRC_CONNECTED态的终端设备SI发生了变化。Short Message中包含了一个systemInfoModification字段(通知MSI/SIB2/SIB3/SIB4/SIB5的变更)和一个etwsAndCmasIndication字段(通知SIB6/SIB7/SIB8的变更)。如果终端设备接收到的Short Message消息包含systemInfoModification字段或etwsAndCmasIndication字段，则表示SI将在下一个变更周期发生变化。方式2中，网络设备通过SIB1中的SI-SchedulingInfo->SchedulingInf->sib-MappingInfo包含的valueTag字段，指示SI是否发生了变化，valueTag的取值范围在0～31之间。终端设备可以使用valueTag字段检验之前保存的SI是否有效。如果valueTag的值发生了变化，终端设备认为其所保存的SI无效，需要重新读取更新后的SI。如果valueTag的值未没有发生变化，终端设备认为其所保存的SI依然有效。另外，终端设备中保存的SI存在设定时长的有效期，如有效期为3个小时，终端设备从接收到SI开始判断3个小时内valueTag的值是否发生了变化，如果3个小时内valueTag的值未发生变化，则终端设备在3个小时内保存的SI有效。一般的，除MIB和SIB1外，其余的SIB都有自己对应的valueTag。
Paging DCI还可以用于指示通知终端设备读取paging消息内容。终端设备可以根据Paging DCI指示的PDSCH资源的时频位置，在该时频位置上获取paging信息内容。
现有技术中对于不同类型的终端设备，采用相同的寻呼配置信息。但是不同类型的终端设备的能力不同，如不同类型的终端设备寻呼概率不同，就会导致寻呼概率较低的终端设备被频繁唤醒导致高能耗，又如不同类型的终端设备所需的系统信息不同，终端设备需要读取SIB1中特定字段才能确定更新的系统信息是否为自身所需要，对于需要系统信息较少的终端设备来说，这些终端设备就需要频繁读取SIB1来判断自身所需要的系统信息是否发生了更新，因此频繁读取也会导致高能耗的问题。综上，对于不同类型的终端设备采用相同的寻呼配置信息，可能会导致高能耗的问题出现。
鉴于此，为了降低寻呼过程中的能耗，本申请提出一种寻呼方法来为不同类型的终端设备设置对应的寻呼配置信息，以保证不同类型的终端设备采用对应的寻呼配置信息参与寻呼过程，避免终端设备被频繁唤醒及频繁读取SIB1信息，从而实现寻呼过程中的节能。
在该方法中，根据不同类型的终端设备的能力不同，在寻呼过程中，网络设备为不同类型的终端设备发送对应的寻呼配置信息，第一类型终端设备根据对应的第一寻呼配置信息，接收对应的paging DCI，第二类型终端设备根据对应的第二寻呼配置信息，接收对应的paging DCI。由于通过该方法，网络设备针对不同类型的终端设备单独进行寻呼配置和单独进行paging DCI的指示，因此终端设备根据对应的寻呼配置信息，在接收到paging DCI 的指示时，再执行获取系统信息或读取paging消息内容等步骤，从而避免终端设备被频繁唤醒及频繁读取SIB1信息，降低寻呼过程中的能耗，达到节能的目的。
本申请涉及两种类型的终端设备，本文将这两种类型的终端设备称为第一类型终端设备和第二类型终端设备。第一类型终端设备和第二类型终端设备的能力不同。具体的，两种类型终端设备可以具备下述一项或者多项区别特征：

(5)支持的载波聚合能力不同，例如，第一类型终端设备可以支持载波聚合，而第二类型终端设备不支持载波聚合；又例如，两类终端设备都可以支持载波聚合，但是第一类型终端设备同时支持的载波聚合的最大个数大于第二类型终端设备同时支持的载波聚合的最大个数，例如第一类型终端设备可以最多同时支持5个载波或者32个载波的聚合，而第二类型终端设备最多同时支持2个载波的聚合。

具体的，在本申请中，两种类型的终端设备中的第二类型终端设备可以为降低性能(reduced capability)终端设备、第一类型终端设备可以为非降低性能终端设备，或者，第一类型终端设备可以为与第二类型终端设备不同的降低性能终端设备，或者为兼具降低性能与非降低性能功能的终端设备(例如，NR Release 15，和/或NR Release 16的终端设备，也可以是未来无线通信系统中演进的终端设备，不限于LTE终端设备、以及NR终端设备)，其中，降低性能终端设备可以对应如上区别特征描述中能力较低的终端设备；或者，两种类型的终端设备可以同为降低性能终端设备，但是两种终端设备之间存在如上区别特征，例如，两种类型的终端设备同为降低性能终端设备，一种终端设备在一个载波上的数据传输带宽最大可以为20MHz，另外一种终端设备在一个载波上的数据传输带宽最大为10MHz。此外，降低性能(NR reduced capability，NR REDCAP)终端设备也可以称为NR-light终端设备。需要说明的是，以上对于两种类型终端设备的说明仅为可能的应用，本申请实施例提供的通信方法可以适用于两种不同能力的终端设备，针对不同能力的终端设备发送不同的寻呼配置信息，以区分两种终端设备接收寻呼的时间和频率，为终端设备减少不必要的能耗。
可选的，终端设备的能力包括但不限于以下一种或多种：最大传输带宽、传输速率、可靠性、时延容忍度、天线数量、续航时间、终端尺寸、终端的硬件能力或终端的成本复杂度等。可以理解的是不同类型终端设备除具备上述一项或者多项区别特征，在本申请中不同类型的终端设备在终端设备具体的上述一种或多种能力上，也可以存在区别。其中最大传输带宽指终端设备(或者终端设备所在通信线路)在单位时间段内能够最大传输的数据量，最大传输带宽能够标识终端设备(或者终端设备所在通信线路)的数据传输能力。传输速率指单位时间内传输的数据量大小，传输速率用于衡量通信系统传输能力。可靠性可以通过终端设备的业务质量和/或错误率等指标来表征。时延容忍度指终端设备在通信过程中能够接收的最大时延。天线数量是终端设备上设置的天线的数量。续航时间一般与终端设备的电池容量和/或终端设备参与的业务有关。终端尺寸指终端的机身尺寸。终端的硬件能力可以包括终端的网络能力等。终端设备的成本复杂度可以为终端设备在生产时的制作工艺的复杂度以及所花费的成本等。
本申请实施例提供了一种寻呼方法，该方法可以应用于如图1所示的通信系统中。下面参考图3，详细说明寻呼方法的具体过程。如图3所示，该过程包括：
S301：网络设备发送第一寻呼配置信息，所述第一寻呼配置信息对应于第一类型终端设备，所述第一类型终端设备接收所述第一寻呼配置信息。
所述网络设备可以为核心网设备和/或接入网设备，例如所述网络设备可以为基站。
示例性的，第一类型终端设备可以为非降低性能终端设备(如NR legacy UE)，也可以为和第二类型终端设备不同的降低性能终端设备。在本申请实施例中NR legacy UE可以理解为现有类型的终端设备。
一种可能的实现方式中，所述第一寻呼配置信息中包括但不限于以下一种或多种：所述第一类型终端设备检测PDCCH的时机，所述第一类型终端设备对应的无线传输资源，用于指示后续PO后有paging DCI通知所述第一类型终端设备获取更新的系统信息或指示存在所述第一类型终端设备的寻呼调度信息的信息。
第一类型终端设备根据第一寻呼配置信息接收寻呼消息。具体的，若所述第一寻呼配置信息包括所述第一类型终端设备检测PDCCH的时机，所述第一类型终端设备可以在该时机检测PDCCH，从而检测到paging DCI。若所述第一寻呼配置信息包括所述第一类型终端设备对应的无线传输资源，所述第一类型终端设备可以在对应的时频资源上检测paging DCI。所述第一类型终端设备会接收指示信息，且该指示信息用于指示后续PO有paging DCI通知所述第一类型终端设备获取更新的系统信息，所述第一类型终端设备可以监听后续的一个或多个PO，以获取到paging DCI，进而根据paging DCI的指示，获取更新的系统信息。所述第一类型终端设备会接收指示信息，且该指示信息用于指示后续PO有paging DCI指示存在所述第一类型终端设备的寻呼调度信息，所述第一类型终端设备可以在监听后续的一个或多个PO，以获取到paging DCI等，进而根据paging DCI的指示，在对应的PDSCH资源上读取paging消息内容(paging message)。
在S301之前，所述第一类型终端设备还可以向网络设备上报与paging相关的能力信息，和/或上报所述第一类型终端设备的第一类型。所述网络设备根据所述第一类型终端设备与paging相关的能力信息，和/或所述第一类型，可以确定所述第一类型终端设备对应的所述第一寻呼配置信息。例如，所述第一类型终端设备在向网络设备的注册过程中，上报与paging相关的能力信息，和/或上报所述第一类型终端设备的第一类型。
S302：所述网络设备发送第二寻呼配置信息，所述第二寻呼配置信息对应于第二类型终端设备，所述第二类型终端设备接收所述第二寻呼配置信息。
示例性的，第二类型终端设备可以为降低性能终端设备(reduced capability UE)，在本申请实施例中降低性能终端设备也称为NR-light UE，第二类型终端设备可以理解为新增类型的终端设备。
在S302之前，所述第二类型终端设备还可以向网络设备上报具备的paging能力信息，和/或上报所述第二类型终端设备的第二类型，paging能力信息能够用于确定终端设备的类型。所述网络设备根据所述第二类型终端设备具备的paging能力信息，和/或所述第二类型，可以确定所述第二类型终端设备对应的所述第二寻呼配置信息。例如所述第二类型终端设备在向网络设备的注册过程中，上报具备的paging能力信息，和/或上报所述第二类型终端设备的第二类型。
可以理解的是，第一寻呼配置信息和第二寻呼配置信息可以分别承载于两条不同的消息中下发给第一类型终端设备和第二类型终端设备，或者第一寻呼配置信息和第二寻呼配置信息可以承载于一条消息中下发给第一类型终端设备和第二类型终端设备。例如若第一寻呼配置信息和第二寻呼配置信息分别承载于两条不同的消息中，网络设备将承载第一寻呼配置信息的第一消息中发送给第一类型终端设备，第一类型终端设备接收并保存第一寻呼配置信息；网络设备将承载第二寻呼配置信息的第二消息中发送给第二类型终端设备，第二类型终端设备接收并保存第二寻呼配置信息。其中第一消息和第二消息为不同的消息，第一消息和第二消息可以为现有的消息，也可以为新增的消息。当第一寻呼配置信息和第二寻呼配置信息分别承载于不同的消息时，S301或S302为可选的步骤，且S301和S302之间 没有依赖关系，对于第一类型终端设备仅需要接收第一寻呼配置信息，对于第二类型终端设备仅需要接收第二寻呼配置信息。又如若第一寻呼配置信息和第二寻呼配置信息承载于一条消息中，在第三消息中承载有第一寻呼配置信息和第二寻呼配置信息，网络设备将第三消息发送给第一类型终端设备和第二类型终端设备，第一类型终端设备接收第三消息，在第三消息中识别第一寻呼配置信息，并保存第一寻呼配置信息，第二类型终端设备接收第三消息，在第三消息中识别第二寻呼配置信息，并保存第二寻呼配置信息，其中第三消息可以为现有的消息，也可以为新增的消息。
另外可选的，第一寻呼配置信息包括第一类型终端设备对应的寻呼周期，第二寻呼配置信息包括第二类型终端设备对应的寻呼周期。第一类型终端设备对应的寻呼周期与第二类型终端设备对应的寻呼周期不同。例如，由于第二类型终端设备的业务特性，第二类型终端设备的寻呼概率低于第一类型终端设备的寻呼概率，因此第二类型终端设备的寻呼周期可以长于第一类型终端设备的寻呼周期，这样，相比于第一类型终端设备，第二类型终端设备的休眠时间较长，唤醒频率较低，从而进一步降低寻呼过程中的能耗。以第一寻呼配置信息和第二寻呼配置信息携带在一条消息中为例，第一类型终端设备可以根据接收到的两个寻呼周期，选取两个寻呼周期中较短的寻呼周期，确定为第一类型终端设备对应的寻呼周期，第二类型终端设备可以根据接收到的两个寻呼周期，选取两个寻呼周期中较长的寻呼周期，确定为第二类型终端设备对应的寻呼周期。
例如图4中所示，第一寻呼配置信息中包括的寻呼周期T为320毫秒(ms)，密度为T/4，即在每个寻呼周期(320ms)内，有8个系统帧可以作为PF，在640ms内，终端设备监听两个PF中的PO。第二寻呼配置信息中包括的寻呼周期T为640ms，密度为T/4，即在每个寻呼周期(640ms)内，有16个系统帧可以作为PF，在640ms内，终端设备监听一个PF中的PO。可见，图4中第一类型终端设备的寻呼周期小于第二类型终端设备的寻呼周期，若第一类型终端设备和第二类型终端设备的PF以相同的密度分布，第二类型终端设备监听PO的频率变低，因此第二类型终端设备的能耗也变低。一种可能的情况下，计算得到的PF和PO中网络设备有可能同时寻呼第一类型终端设备和第二类型终端设备，即可能在某个PO，第一类型终端设备和第二类型终端设备均可以监听到paging DCI。
网络设备为不同类型的终端设备配置对应的配置信息，可以使得终端设备在满足其自身对应的配置信息所指示的资源时，去接收寻呼消息，而在不满足其对应的配置信息所指示的资源时，不去接收寻呼消息，从而减少终端设备的能耗。
S303：所述网络设备根据所述第一寻呼配置信息，向所述第一类型终端设备发送paging DCI，所述第一类型终端设备接收paging DCI；和/或所述网络设备根据所述第二寻呼配置信息，向所述第二类型终端设备发送paging DCI，所述第二类型终端设备接收paging DCI。
寻呼过程包括核心网发起的寻呼过程(CN-paging)、接入网发起的寻呼过程(RAN-paging)或用于通知系统信息变更的寻呼过程中的一种或多种。
对于CN-paging，以网络设备为基站为例，在S303之前，基站还可以从核心网设备接收第四消息，第四消息用于通知基站接收paging DCI的终端设备的类型。若第四消息通知第一类型终端设备接收paging DCI，基站根据第一寻呼配置信息，向第一类型终端设备发送paging DCI。若第四消息通知第二类型终端设备接收paging DCI，基站根据第二寻呼配置信息，向第二类型终端设备发送paging DCI。
对于RAN-paging和用于通知系统信息变更的寻呼过程，以网络设备为基站为例，在 S303之前，基站可以确定接收paging DCI的终端设备的类型，若确定第一类型终端设备接收paging DCI，基站根据第一寻呼配置信息，向第一类型终端设备发送paging DCI，若确定第二类型终端设备接收paging DCI，基站根据第二寻呼配置信息，向第二类型终端设备发送paging DCI。
其中发送给第一类型终端设备的paging DCI用于通知第一类型终端设备获取更新的系统信息，或者指示存在第一类型终端设备的寻呼调度信息(即通知第一类型终端设备读取paging DCI指示的PDSCH资源上的paging消息内容)。其中，发送给第一类型终端设备的paging DCI包括PDSCH资源的位置，第一类型终端设备可以在对应的PDSCH资源的位置上读取paging消息内容。发送给第二类型终端设备的paging DCI用于通知第二类型终端设备获取更新的系统信息，或者指示存在第二类型终端设备的寻呼调度信息(即通知第二类型终端设备读取paging DCI指示的PDSCH资源上的paging消息内容)。其中，发送给第二类型终端设备的paging DCI包括PDSCH资源的位置，第二类型终端设备可以在对应的PDSCH资源的位置上读取paging消息内容。
在S303中，若发送给第一类型终端设备的paging DCI和第二类型终端设备的paging DCI不同，网络设备向第一类型终端设备和第二类型终端设备发送paging DCI的过程之间没有依赖关系。
在本申请实施例中主要以向第二类型终端设备发送paging DCI为例对寻呼过程进行说明。对于涉及到第一类型终端设备的寻呼过程，可以参见第二类型终端设备的寻呼过程，或采用现有技术中所示的寻呼过程，即本申请实施例中可以对现有的第一类型终端设备的寻呼过程和新增的第二类型终端的寻呼过程进行改进，也可以仅对新增的第二类型终端设备的寻呼过程进行改进。
示例性的，在本申请实施例中，可以通过以下几种实现方式向第二类型终端设备发送paging DCI。
方式一：网络设备可以预先将SIB划分为多个SIB组(group)，每个SIB组内包括一个或多个SIB，不同类型的终端设备可以对应不同的SIB组。进一步，网络设备还可以预先设置指示信息与SIB组的对应关系。其中，每个SIB组的划分信息和/或SIB组与终端设备的对应关系可以通过第一信息来指示，第一信息的定义详见后文的相关说明。这样，网络设备可以通过paging DCI中的指示信息来指示对应的SIB组是否变化，终端设备根据paging DCI中的指示信息确定自己对应的SIB是否发生变化，在有变化时，获取更新的系统信息，在没有变化时，无需重复获取系统信息，从而降低寻呼过程中的能耗。
可选的，网络设备可以是依据终端设备的类型划分SIB组，或者可以是根据业务需要划分SIB组。若根据终端设备的类型划分SIB组，网络设备可以划分第一类型终端设备对应的SIB组和第二类型终端设备对应的SIB组。第一类型终端设备对应的SIB组中包括第一类型终端设备需要的SIB，第二类型终端设备对应的SIB组中包括第二类型终端设备需要的SIB，例如第二类型终端设备对应的SIB组中可以包括SIB2，SIB3，SIB4或SIB5中的一种或多种。一种可能的实现方式中，由于第二类型终端设备的业务特性，相比于第一类型终端设备，第二类型终端设备需要的SIB更少，因此相比于第一类型终端设备对应的SIB组中包括的SIB，第二类型终端设备对应的SIB组中包括的SIB较少。每个类型的终端设备可以对应一个或多个SIB组。若根据业务需要划分SIB组，网络设备可以划分第一业务对应的SIB组，第二业务对应的SIB组和第三业务对应的SIB组。以几个典型的应用场景为例，不同应 用场景下的业务需求不同，例如包括工业无线传感器，视频监控和可穿戴设备，可穿戴设备对应的SIB组可以包括SIB6，SIB7或SIB8中的一种或多种，其中SIB6，SIB7或SIB8是与公共预警相关的系统信息。而对于工业无线传感器和视频监控的场景，可能需要SIB6，SIB7或SIB8等与公共预警相关的系统信息，也可能不需要SIB6，SIB7或SIB8等与公共预警相关的系统信息，因此可以依据不同的实际需求，来确定工业无线传感器和视频监控的场景是否需要SIB6，SIB7或SIB8等系统信息。
在S303之前，网络设备还可以发送第一信息，所述第一信息用于指示每个SIB组包含的SIB，所述第二类型终端设备接收第一信息，根据自身的使用需求确定自身对应的SIB组。可选的，所述第一信息还可以用于指示所述第二类型设备对应的SIB组，即第一信息直接指示终端设备的类型与SIB组的对应关系，所述第二类型终端设备根据接收到的第一信息，可以直接确定自身对应的SIB组。可选的，第一信息可以是通过第二寻呼配置信息传输的，也可以是通过新增的消息传输的，或者也可以是在paging DCI(如第一paging DCI)中包括第一信息，或者可以是在现有的其他系统信息中包括第一信息。
在执行S303时，网络设备发送第一paging DCI，所述第一paging DCI包括指示信息集合，所述指示信息集合包括至少一个指示信息，所述至少一个指示信息用于标识对应的SIB组是否变化，所述SIB组变化包括所述SIB组内任一SIB发生变化。示例性的，指示信息集合中的元素与SIB组集合中的元素一一对应，即每个指示信息用于指示一个对应的SIB组。第二类型终端设备接收到第一paging DCI可以判断自己对应的SIB组是否发生变化，SIB组变化包括SIB组内任一SIB发生变化。也就是说，如果第二类型终端设备对应的SIB组发生变化，则可以确定该第二类型终端设备需要的SIB发生了更新，第二类型终端设备需要获取更新后的系统信息。具体的，指示信息用于标识对应的SIB组变化，或者指示信息用于标识对应的SIB未发生变化。
指示信息集合和指示信息可以是复用已有字段(如冗余比特的字段)，可以是新增字段等。例如指示信息集合为Short Message或Short Message中的部分比特，指示信息集合中包括多个冗余比特，将冗余比特作为新增的指示信息的字段，如Short Message bits，不同的Short Message bits分别指示对应的SIB组是否发生变化，以指示对应的SIB组中是否有SIB发生变化。
可以理解的，在该方式中，该S303步骤的执行不依赖于第一信息的发送与否，网络设备可以和终端设备预先约定指示信息集合中每个指示信息的含义。这样，网络设备可以通过指示信息集合中的元素，直接指示终端设备对应的SIB组是否发生变化，从而指示终端设备是否去获取新的系统信息。例如，网络设备和终端设备约定使用Short Message中的一个比特，用于指示第二类型终端设备所需要的系统信息未发生更新(即相当于触发第二类型终端设备不需要系统信息)，或指示第二类型终端设备所需要的系统信息发生了更新(即相当于触发第二类型终端设备需要获取更新的系统信息)。或者，例如网络设备和终端设备约定使用Short Message中的一个比特,用于指示特定SIB是否发生变化，该SIB组事先约定包含SIB2，SIB3，SIB4或SIB5中的一种或多种，从而网络设备可以直接指示需要对应的SIB组中的SIB的终端设备获取新的系统信息。
方式二：在执行S303时，所述网络设备可以发送第二paging DCI，所述第二paging DCI对应于所述第二类型终端设备，所述第二paging DCI包括第二信息，所述第二信息用于通知所述第二类型终端设备获取更新的系统信息或指示存在所述第二类型终端设备的寻呼 调度信息，或者所述第二信息用于通知所述第二类型终端设备不获取更新的系统信息或指示不存在所述第二类型终端设备的寻呼调度信息。这样，如果接收到第二paging DCI，第二paging DCI对应于第二类型终端设备，且第二信息通知所述第二类型终端设备获取更新的系统信息或指示存在所述第二类型终端设备的寻呼调度信息，第二类型终端设备可以根据第二paging DCI中第二信息的指示，获取更新的系统信息或读取paging消息内容；如果第二信息指示所述第二类型终端设备不获取更新的系统信息，或指示不存在第二类型终端设备的寻呼调度信息，或者第二类型终端设备未接收到第二paging DCI，或者接收到的paging DCI并非对应于第二类型终端设备，第二类型终端设备无需执行获取系统信息或读取paging消息内容等步骤，从而降低寻呼过程中的能耗。
其中，第二paging DCI与第二类型终端设备的对应关系可以通过以下至少一种方式来指示：
1)网络设备可以通过隐式的方式来进行指示。如网络设备可以为不同类型的终端设备定义不同的paging DCI格式(format)，如定义第一类型终端设备对应的paging DCI的格式及定义第二类型终端设备对应的paging DCI的格式，和/或网络设备采用第一类型终端设备对应的P-RNTI加扰PDCCH，及采用第二类型终端设备对应的P-RNTI加扰PDCCH。这样，终端设备在接收到自身对应的paging DCI的格式时，才执行获取系统信息或读取paging消息内容等步骤，在没有接收到的自身对应的paging DCI的格式时，无需执行获取系统信息或读取paging消息内容等步骤，从而进一步降低寻呼过程中能耗。
又例如，网络设备通过加扰参数来指示第二paging DCI与第二类型终端设备的对应关系。具体的，所述第二paging DCI承载于第一PDCCH，第一PDCCH是通过第一P-RNTI加扰的，所述第一P-RNTI对应第二类型终端设备。对于第二类型终端设备来说，第二类型终端设备能够根据自身对应的第一P-RNTI成功解扰第一PDCCH，从而第二类型终端设备确定第一PDCCH承载的第二paging DCI为发送给第二类型终端设备的paging DCI。对于第一类型终端设备来说，第一类型终端设备无法根据自身对应的第二P-RNTI成功解扰第一PDCCH，第一类型终端设备确定第一PDCCH承载的第二paging DCI非发送给第一类型终端设备的paging DCI。对应的，发送给第一类型终端设备的paging DCI承载于第二PDCCH，第二PDCCH通过第二P-RNTI加扰，第二P-RNTI对应于第一类型终端设备。第二类型终端设备无法根据自身对应的第一P-RNTI成功解扰第二PDCCH，第二类型终端设备确定第二PDCCH承载的paging DCI非发送给第二类型终端设备的paging DCI，第二类型终端设备不执行获取系统信息或读取paging消息内容等步骤。其中第一PDCCH和第二PDCCH是否相同在此不进行限定。例如第一PDCCH和第二PDCCH相同时，承载于该第一PDCCH/第二PDCCH的paging DCI同时指示第一类型终端设备和第二类型终端设备。
又如，网络设备通过第二paging DCI的格式来指示与第二类型终端设备的对应关系。具体的，所述第二paging DCI的格式对应于所述第二类型终端设备。终端设备可以根据paging DCI的格式确定该paging DCI是否为发送给自己的paging DCI。第二类型终端设备可以根据第二paging DCI的格式，确定第二paging DCI为发送给第二类型终端设备的paging DCI，第一类型终端设备根据第二paging DCI的格式，可以确定第二paging DCI非发送给第一类型终端设备的paging DCI。其中，所述格式也可以理解为传输形式。
2)网络设备也可以通过显式的方式来进行指示，所述第二信息可以通过预留的字段来指示。例如采用paging DCI中的6个冗余比特来指示第二信息。
方式三：网络设备为不同类型的终端设备配置不同的无线传输资源，不同类型的终端设备只需在自己对应的无线传输资源上监听paging DCI，如果未监听到paging DCI，则无需执行获取系统信息或读取paging消息内容等步骤，从而降低寻呼过程中的能耗。
例如，所述第二寻呼配置信息还包括第三信息，所述第三信息用于指示终端设备对应的无线传输资源，所述无线传输资源包括时域资源、频域资源或码域资源中的一种或多种。第二寻呼配置信息中第三信息指示的终端设备对应的无线传输资源，即为第二类型终端设备对应的无线传输资源。
所述无线传输资源包括：Search Space和/或CORESET；和/或P-RNTI。
其中，不同类型的终端设备对应的无线传输资源不同，其中时域资源和频域资源不同包括：不同类型的终端设备对应的Search Space和/或CORESET不同，码域资源不同包括：不同类型的终端设备对应的P-RNTI不同。
在该方式中，所述网络设备根据所述第二类型终端设备对应的无线传输资源，发送第三paging DCI。对应的，所述第二类型终端设备根据对应的无线传输资源，接收第三paging DCI。
以图5为例对该方式三中时频资源不同进行说明，第一类型终端设备的paging DCI在浅色部分的时频资源发送，第二类型终端设备的paging DCI在深色部分的时频资源发送，其中CORESET1为第一类型终端设备使用的CORESET，SearchSpace1为第一类型终端设备使用的SearchSpace，CORESET2为第二类型终端设备使用的CORESET，SearchSpace2为第二类型终端设备使用的SearchSpace。A方式中第一类型终端设备和第二类型终端设备使用不同的CORESET和不同的SearchSpace，B方式中第一类型终端设备和第二类型终端设备使用相的CORESET和不同的SearchSpace，C方式中第一类型终端设备和第二类型终端设备使用不同的CORESET，对SearchSpace不做限制(图5中所示的第一类型终端设备和第二类型终端设备的SearchSpace相同)，D方式中第一类型终端设备和第二类型终端设备使用不同的CORESET，对SearchSpace不做限制(图5中所示的第一类型终端设备和第二类型终端设备的SearchSpace相同)。若使用A和C方式进行时频资源配置时，若paging DCI用于通知第一类型终端设备获取更新的系统信息或指示存在第一类型终端设备的寻呼调度信息时，第二类型终端设备不会监听到该paging DCI，不执行获取系统信息或读取paging消息内容等步骤，若paging DCI用于通知第二类型终端设备获取更新的系统信息或指示存在第二类型终端设备的寻呼调度信息时，第一类型终端设备不会监听到该paging DCI，不执行获取系统信息或读取paging消息内容等步骤。若使用B和D方式进行时频资源配置时，第一类型终端设备的paging DCI和第二类型终端设备的paging DCI在两个不同的时频资源上发送，若paging DCI用于通知第一类型终端设备获取更新的系统信息或指示存在第一类型终端设备的寻呼调度信息时，第二类型终端设备不会监听到该paging DCI，不执行获取系统信息或读取paging消息内容等步骤，若paging DCI用于通知第二类型终端设备获取更新的系统信息或指示存在第二类型终端设备的寻呼调度信息时，第一类型终端设备不会监听到该paging DCI，不执行获取系统信息或读取paging消息内容等步骤。实现了paging DCI的分开调度，从而达到节能的目的。
方式四：网络设备可以通知终端设备后续的一个或多个PO有paging DCI，所述pagingDCI用于通知终端设备获取更新的系统信息，或所述pagingDCI用于指示存在终端设备的寻呼调度信息。
可以理解的是，网络设备可以通过第四信息来指示终端设备确定是否接收后续PO中的paging DCI，以减少终端设备的能耗。例如，网络设备通过第四信息通知第一类型终端设备获取更新的系统信息或指示存在终端设备的寻呼调度信息，即网络设备通过第四信息通知第一类型终端设备后续一个或多个PO有paging DCI，所述paging DCI用于通知第一类型终端设备获取更新的系统信息，或者所述paging DCI指示存在第一类型终端设备的寻呼调度信息。第一类型终端确定后续PO中的paging DCI针对第一类型终端设备进行指示，第一类型终端设备监听对应的PO，而第二类型终端设备确定后续PO中的paging DCI不是针对第二类型终端设备进行指示，第二类型终端设备可以不监听对应的PO，从而降低寻呼过程中的能耗。同理又如，网络设备通过第四信息通知第二类型终端设备获取更新的系统信息或指示存在终端设备的寻呼调度信息，即网络设备通过第四信息通知第二类型终端设备后续一个或多个PO有paging DCI，所述paging DCI用于通知第二类型终端设备获取更新的系统信息，或者所述paging DCI指示存在第二类型终端设备的寻呼调度信息。第二类型终端确定后续PO中的paging DCI针对第二类型终端设备进行指示，第二类型终端设备监听对应的PO，而第一类型终端设备确定后续PO中的paging DCI不是针对第一类型终端设备进行指示，第一类型终端设备可以不监听对应的PO，从而降低寻呼过程中的能耗。
具体的，第四信息可以指示以下至少一个：
(1)在后续的PO有paging DCI用于通知第一类型终端设备和/或第二类型终端设备进行系统消息的更新。
(2)在后续的PO有paging DCI用于通知第一类型终端设备和/或第二类型终端设备读取paging消息内容。
终端设备在接收第四信息之后，可以根据第四信息判断后续PO中的paging DCI是否是对应类型的paging DCI，进一步，终端设备还可以判断paging DCI的发起原因是系统信息的更新还是paging消息的调度，进而，终端设备可以确定是否需要接收所述paging DCI，避免由于不必要的大量监听而消耗过多能量。例如，若第四信息指示后续PO中的paging DCI针对第一类型终端设备通知系统信息更新，则第一类型终端设备后续接收paging DCI并根据paging DCI中的指示获取更新的系统信息，若第四信息指示后续PO中的paging DCI针对第二类型终端设备通知系统信息更新，则第二类型终端设备后续接收paging DCI并根据paging DCI中的指示获取更新的系统信息，又或者，若第四信息指示后续PO中的paging DCI针对第一类型终端设备通知存在寻呼调度信息，则第一类型终端设备后续接收paging DCI并根据paging DCI的指示读取paging消息内容，若第四信息指示后续PO中的paging DCI针对第二类型终端设备通知存在寻呼调度信息，则第二类型终端设备后续接收pagingDCI并根据paging DCI的指示读取paging消息内容。若第一类型终端设备根据第四信息的指示，确定不需要进行系统信息更新且不需要读取paging消息内容，则第一类型终端设备不需要接收paging DCI，从而减少能量的消耗。若第二类型终端设备根据第四信息的指示，确定不需要进行系统信息更新且不需要读取paging消息内容，则第二类型终端设备不需要接收paging DCI，从而减少能量的消耗。第四信息还可以指示终端设备在后续的哪个或哪些PO上监听paging DCI，例如，网络设备发送第四信息，所述第四信息用于指示在第一PO有第四paging DCI，所述第四paging DCI通知所述第二类型终端设备获取更新的系统信息，或所述第四paging DCI指示存在所述第二类型终端设备的寻呼调度信息；和/或所述第四信息用于指示在第二PO有paging DCI，所述paging DCI通知第一类型终端设备获取更新的系统信息，或 所述paging DCI指示所述第一类型终端设备的寻呼调度信息。第一PO或第二PO可以为下一个变更周期内的PO，或者是后续变更周期内的PO。
具体而言，若第四信息指示在第一PO有第四paging DCI，第二类型终端设备在第一PO上，接收paging DCI。若第二类型终端设备未接收到第四信息，或接收到的第四信息未指示后续有paging DCI，第二类型终端设备不监听对应的PO，从而进一步降低寻呼过程中的能耗。
若所述第四信息用于指示在第二PO有paging DCI，所述paging DCI通知第一类型终端设备获取更新的系统信息，或所述paging DCI指示所述第一类型终端设备的寻呼调度信息，第一类型终端设备在第二PO上监听PDCCH，接收paging DCI。若第一类型终端设备未接收到第四信息，或接收到的第四信息未指示后续有paging DCI，第一类型终端设备不监听对应PO，从而进一步降低寻呼过程中的能耗。
可选的，网络设备还可以发送第五信息，第五信息可以用于指示所述第四信息对应的时频资源，和/或终端设备在哪个或哪些PO上监听paging DCI等与第四信息相关的一些信息。示例性的，终端设备可以在第五信息指示的时频资源的位置上，监听所述第四信息。可选的，第五信息可以携带在第二寻呼配置信息中，可以是携带在新增的消息中，或者可以是携带在现有的其他系统信息中。可以理解的，在该方式中，该发送第四信息步骤的执行不依赖于第五信息的发送与否，网络设备可以和终端设备预先约定第四信息对应的时域资源。
综述，在本申请实施例中，上述方式一至方式四均能够降低寻呼过程中的能耗，达到节能的目的。因此可以理解的是，上述方式一、方式二、方式三和方式四之间可以单独使用，也可以结合使用。并且根据上述实施例中的描述，可见上述几种方式在实现时并不依赖于图3所示的每个步骤，即图3中所示的S301，S302和S303，在实现上述几种方式的过程中为可选的步骤。
通过本申请实施例提供的方案，不同类型的终端设备的能力不同，在寻呼过程中，网络设备为不同类型的终端设备发送对应的寻呼配置信息，第一类型终端设备根据对应的第一寻呼配置信息接收对应的paging DCI，第二类型终端设备根据对应的第二寻呼配置信息，接收对应的paging DCI。由于通过该方法，网络设备针对不同类型的终端设备单独进行寻呼配置和单独进行paging DCI的指示，因此终端设备根据对应的寻呼配置信息，在接收到paging DCI的指示时，再执行获取系统信息或读取paging消息内容等步骤，从而避免终端设备被频繁唤醒及频繁读取SIB1信息，降低寻呼过程中的能耗，达到节能的目的。
下面以第一类型终端设备为NR legacy UE，第二类型终端设备为降低性能UE为例，对寻呼过程进行说明。
如图6所示将上述方式一和方式二结合应用到寻呼过程中，该过程包括以下步骤：
S601：终端设备向核心网设备进行注册，注册时终端设备上报具备的paging能力信息。
终端设备具备的paging能力信息能够用于确定该终端设备的类型，例如确定该终端设备为NR legacy UE或者为降低性能UE。
S602：基站广播寻呼配置信息，该寻呼配置信息包括NR legacy UE对应的第一寻呼配置信息，和降低性能UE对应的第二寻呼配置信息。终端设备接收寻呼配置信息。
该寻呼配置信息可以携带在SIB1中下发。
该寻呼配置信息包括用于计算paging DCI相关的参数，如PF和PO。
第二寻呼配置信息中包括的第二类型终端设备的寻呼周期与第一寻呼配置信息中包括的第一类型终端设备的寻呼周期不同，例如第二寻呼配置信息中的寻呼周期参数大于第一寻呼配置信息中的寻呼周期参数，若终端设备为NR legacy UE，终端设备选取寻呼周期较小的第一寻呼配置信息，若终端设备为降低性能UE，终端设备选取寻呼周期较大的第二寻呼配置信息。
如果预先定义了SIB分组，该寻呼配置信息还包括NR legacy UE对应的SIB组，以及降低性能UE对应的SIB组。例如，该寻呼配置信息包括多个SIB组，及每个SIB组内包含的SIB。终端设备根据自己的需要判断自身对应的一个或多个SIB组，具体的，NR legacy UE确定自身对应的一个或多个SIB组，以及降低性能E确定自身对应的一个或多个SIB组，其中NR legacy UE对应的SIB组和降低性能UE的对应的SIB组可以不同。
S603：核心网发起寻呼流程，核心网设备通知基站paging DCI发送的终端设备的类型，即发送给NR legacy UE还是发送给降低性能UE。
若接入网络发起寻呼流程或用于通知系统信息变更的寻呼过程，基站确定paging DCI发送的终端设备的类型，即发送给NR legacy UE还是发送给降低性能UE。
S604：基站根据终端设备的类型对应的寻呼配置信息，发送paging DCI。终端设备根据自身的类型对应的寻呼配置信息，接收paging DCI。
例如，NR legacy UE根据第一寻呼配置信息确定PF和PO，监听paging DCI。或者降低性能UE根据第二寻呼配置信息确定PF和PO，监听paging DCI。
另外，若paging DCI发送给降低性能UE，基站使用降低性能UE对应的第一P-RNTI对承载paging DCI的第一PDCCH加扰，和/或采用降低性能UE对应的paging DCI的格式，和/或paging DCI中包括第二信息。例如第二信息通知降低性能UE获取更新的系统信息或指示存在降低性能UE的寻呼调度信息，或者第二信息通知降低性能UE不获取更新的系统信息或指示不存在降低性能UE的寻呼调度信息。又如，paging DCI包括Short Message，Short Message中Short Message bits指示降低性能UE对应的SIB发生了变化，从而指示降低性能UE获取更新的系统信息，或者Short Message bits指示降低性能UE对应的SIB未发生变化，从而指示降低性能UE不获取更新的系统信息。
S605：终端设备获取更新的系统信息或读取paging消息内容。
以终端设备为降低性能UE为例，若终端设备采用第一P-RNTI对第一PDCCH解扰成功，确定第一PDCCH承载的paging DCI针对降低性能UE发送，终端设备获取更新的系统信息或读取paging消息内容。和/或若终端设备确定接收到的paging DCI为降低性能UE对应的格式，终端确定paging DCI针对降低性能UE发送，终端设备获取更新的系统信息或读取paging消息内容。和/或若终端设备根据paging DCI中包括的第二信息，确定获取更新的系统信息或读取paging消息内容。和/或若终端设备根据paging DCI中Short Message bits指示降低性能UE对应的SIB发生了变化，终端设备获取更新的系统信息。这种情况下，NR legacy UE不执行获取更新的系统信息或读取paging消息内容等步骤，从而降低寻呼过程中的能耗。
一般的，终端设备在下一个变更周期接收更新的系统信息。
在图6中结合上述方式一和方式二对寻呼过程进行了说明，基站下发了两套寻呼配置信息，不同类型的终端设备可以根据自身的类型，选取使用其中一套对应的寻呼配置信息，并且基站在paging DCI中指示所述paging DCI是针对哪个类型的终端设备进行的发送，终端设备可以更早地确认后续的paging消息是否与自身的类型相关，从而选择性地接收后续的 paging消息，或者选择性地进行获取更新的系统信息或读取paging消息内容的动作，以减少终端设备执行不必要的步骤，从而达到节能的目的。并且图6中基站还为不同类型的终端设备设置了不同的寻呼周期，从而能够减少某一类型终端设备(如降低性能UE)的唤醒次数，从而进一步降低寻呼过程中的能耗。
如图7所示将上述方式三应用到寻呼过程中，该过程包括以下步骤：
S701的执行过程可以参见上述S601，在此不赘述。
S702：基站广播寻呼配置信息，该寻呼配置信息包括NR legacy UE对应的第一寻呼配置信息，和降低性能UE对应的第二寻呼配置信息。终端设备接收寻呼配置信息。
第一寻呼配置信息包括NR legacy UE对应的无线传输资源，第二寻呼配置信息包括降低性能UE对应的无线传输资源。
S703的执行过程可以参见上述S603，在此不赘述。
S704：基站根据终端设备的类型对应的无线传输资源，发送paging DCI。终端设备根据自身的类型对应的无线传输资源，接收paging DCI。
若paging DCI在终端设备的类型为NR legacy UE对应的无线传输资源上发送，终端设备为降低性能UE，终端设备在其对应的无线传输资源上不会接收到paging DCI，也就不会执行获取更新的系统信息或读取paging消息内容等步骤，从而降低寻呼过程中的能耗。
若paging DCI在终端设备的类型为降低性能UE对应的无线传输资源上发送，且终端设备为降低性能UE，终端设备才会执行S705。或者若paging DCI发送的终端设备的类型为NR legacy UE，且终端设备为NR legacy UE，终端设备才会执行S705。
S705的执行过程可以参见上述S605，在此不赘述。
在图7中采用上述方式三对寻呼过程进行了说明，基站下发了两套寻呼配置信息，不同寻呼配置信息指示的无线传输资源不同，也就是说基站为不同类型的终端设备配置了不同的Search Space和/或CORESET和/或P-RNTI，不同类型的终端设备可以根据自身的类型，选取使用其中一套对应的寻呼配置信息，确定对应的无线传输资源，终端设备仅在自身的类型对应的无线传输资源上监听paging DCI，而不会监听到其他类型终端设备的无线传输资源上的paging DCI，避免了终端设备执行不必要的后续步骤，从而达到节能的目的。
如图8所示将上述方式四应用到寻呼过程中，该过程包括以下步骤：
S801的执行过程可以参见上述S601，在此不赘述。
S802：基站广播寻呼配置信息，该寻呼配置信息中包括第五信息，第五信息用于指示第四信息对应的时频资源。
S803-S804的执行过程可以参见上述S603-S604，在此不赘述。
S805：基站发送第四信息，第四信息用于指示后续的PO有paging DCI通知NR legacy UE或降低性能UE获取更新的系统信息或指示存在NR legacy UE或降低性能UE的寻呼调度信息。
或者所述第四信息用于指示后续的PO有paging DCI通知NR legacy UE或降低性能UE不获取更新的系统信息或指示不存在NR legacy UE或降低性能UE的寻呼调度信息。
S806：终端设备根据第四信息，确定是否监听后续的PO。
例如，若第四信息用于指示后续的PO有paging DCI通知降低性能UE获取更新的系统信息或指示存在降低性能UE的寻呼调度信息，终端设备为降低性能UE，终端设备确定监听后续的PO，即监听基站发送的paging DCI；若终端设备为NR legacy UE，终端设备不监听 后续的PO。若第四信息用于指示后续的PO有paging DCI通知NR legacy UE获取更新的系统信息或指示存在NR legacy UE的寻呼调度信息，终端设备为NR legacy UE，终端设备确定监听后续的PO，即监听基站发送的paging DCI；若终端设备为降低性能UE，终端设备不监听后续的PO。
在图8中采用上述方式四对寻呼过程进行了说明，基站下发了第四信息对应的时频资源，基站在所述时频资源上发送第四信息，终端设备在所述时频资源上接收第四信息，第四信息指示后续PO上的paging DCI是针对哪个类型的终端设备进行的发送，终端设备可以更早地确认后续的paging消息是否与自身的类型相关，从而选择性地接收后续的paging消息，或者选择性地进行获取更新的系统信息或读取paging消息内容的动作，以减少终端设备执行不必要的步骤，从而达到节能的目的。
