Description

监听寻呼消息、唤醒信号、切换覆盖模式的方法及装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种监听寻呼消息或唤醒信号的方法、对终端设备的寻呼或唤醒方法、覆盖模式的切换方法及装置。
背景技术
终端设备能够在蜂窝通信网络(或无线通信网络)中进行无线的通信，该通信可以经由包括在该蜂窝通信网络之内的一个或更多核心网络(core network，CN)以及无线电接入网络(radio access network,RAN)而执行。终端设备可以是例如用户设备(user equipment，UE)、移动终端或无线终端、移动电话、诸如例如膝上型计算机的计算机、个人数字助理或平板计算机，或者能在蜂窝通信网络中通信的任何其他无线电网络单元。终端设备可还被称作机器类型通信(Machine Type Communication，MTC)终端设备、蜂窝物联网(internet of things，IoT)装置的IoT终端设备。蜂窝通信网络被划分为小区区域的地理区域，其中每个小区区域由诸如基站的接入节点所服务。小区可以理解是地理区域，其中无线电覆盖由在基站站点的基站所提供，处于基站站点的一个基站可服务一个或若干小区。不同基站或同一基站的不同副天线的无线电覆盖区域通常会有重叠部分，因此，终端设备在同一位置可能同时接收到多个小区的信号。在空闲态下，终端设备根据小区选择标准(比如驻留小区的小区选择S准则)选择合适的小区进行驻留，之后可以监听驻留小区的寻呼消息。寻呼消息可以由核心网网元，比如4G网络架构中的移动性管理实体(mobility management entity，MME)，在接收到下行数据通知时触发，也可以由接入节点，比如基站，在系统消息变更时触发。当有上行数据发送请求时，或者在监听到驻留小区对自身的寻呼时，UE可以向驻留小区的基站发起随机接入请求。在本申请的上下文中，表述“上行数据”可以指从终端设备到基站的待传输数据，表述“下行数据”可以指从基站到终端设备的待传输数据。
每个基站可以支持一个或若干无线通信技术，其中，长期演进(long term evolution，LTE)作为第四代(the fourth generation，4G)无线通信技术获得广泛的关注。图1为LTE系统的结构示意图，参考图1，LTE的无线电接入网络包括接入节点——演进节点B(evolved node B，eNB)，图1以三个接入节点eNB1、eNB2和eNB3为例，LTE的无线电接入网络还包括核心网网元，图1以MME4和服务网关(serving gateway，S-GW)5为例。终端设备6通过eNB1、eNB2或eNB3和S-GW5连接至外部网络。eNB1、eNB2和eNB3与终端设备6通过无线电信道连接，S-GW5是提供数据承载的设备，并在MME4的控制下产生或者移除数据承载，MME4管理终端设备6的各种控制功能以及移动性管理功能，并与eNB1、eNB2和eNB3连接。已经引进支持各种终端类型的技术用于LTE系统中，其中的一项技术支持MTC终端设备，MTC终端设备要求支持深度无线电覆盖(也可称为增强覆盖或扩展覆盖或覆盖增强或覆盖扩展)。MTC终端设备的示例是自动化工业中的传感器、电表和追踪装置等，深度无线电覆盖的区域的示例可以是公寓地下室。扩展覆盖(Coverage enhancement，CE)基于重复的传送方案,除了用于带宽减少低复杂度(Bandwidth reduced and Low complexity,BL)的终端设备，比如MTC终端设备，扩展覆盖还可以用于非BL终端设备，比如non-BL UE等。支持扩展覆盖的发送端，比如终端设备或基站，在扩展覆盖下，可以经由扩展覆盖信道重复多次发送 数据，支持扩展覆盖的接收端，比如基站或终端设备，可以合并多次接收的数据，从而实现提高数据接收成功率的目的。相对于扩展覆盖，原始无线电通信系统(如LTE系统)所支持的覆盖称为正常覆盖(normal coverage，NC)。图2为蜂窝通信系统中支持扩展覆盖的终端设备在小区内的覆盖模式分布示意图，终端设备在区域A内处于正常覆盖，在环形区域B内处于扩展覆盖。本申请中，正常覆盖和扩展覆盖可以统称为覆盖模式，正常覆盖和扩展覆盖也可称为正常覆盖模式和扩展覆盖模式。本申请中，正常覆盖还可以理解为在整个系统带宽上进行数据通信，扩展覆盖可以理解为在部分或全部系统带宽上进行数据通信，例如，在6个物理资源块(Physical Radio Block,PRB)上进行数据通信或在1.4MHz上进行数据通信。
现有技术中，终端设备通过判断小区选择S准则选择驻留的小区，并进一步的确定其在驻留小区所处的覆盖模式，之后可以选择相应的覆盖模式进行数据发送和接收。当终端设备满足正常覆盖的小区选择S准则时，终端设备一定满足扩展覆盖的小区选择S准则，因此，利用小区选择S准则确定终端设备所处的覆盖模式时，若终端设备确定其满足正常覆盖的小区选择S准则，则终端设备确定其处于正常覆盖；若终端设备确定其不满足正常覆盖的小区选择S准则，但是满足扩展覆盖的小区选择S准则，则终端设备确定其处于扩展覆盖。基于图1的结构示意图，终端设备6在空闲态可以根据小区选择S准则进行小区选择，假设选择eNB1的小区进行驻留，并根据小区选择S准则选择相应的覆盖模式，之后可以在相应的覆盖模式下接收eNB1发送的系统消息和寻呼消息，在MME4接收到下行数据通知时，MME4向eNB1发送寻呼消息，eNB1根据该MME4发送的寻呼消息发起对终端设备6的寻呼，终端设备6可以在接收到对自身设备的寻呼消息后向eNB1发起随机接入请求。现有技术中，扩展覆盖可以支持唤醒信号(wake up signal，WUS)，若终端设备6选择扩展覆盖，那么终端设备可以根据扩展覆盖下的系统消息监听扩展覆盖下的唤醒信号，若接收到唤醒信号，则开始监听扩展覆盖下的寻呼消息。
在空闲态，终端设备在正常覆盖下会在整个系统带宽上接收系统消息和寻呼消息，而在扩展覆盖下，终端设备会在较窄的带宽下接收系统消息和寻呼消息。由于终端设备在较宽的带宽下监听系统消息和寻呼消息的功耗更高，并且终端设备监听唤醒信号的功耗小于监听寻呼消息的功耗，因此终端设备工作在正常覆盖的功耗通常大于扩展覆盖的功耗。随着网络设备的性能和覆盖率的提高，可预期的是，无线电通信系统中大部分终端设备或者终端设备在大部分时间内将处于正常覆盖下，因此，终端设备在空闲态下的功耗普遍较高，不利于延长终端设备的续航时长。

具体实施方式
本申请实施例提供了一种监听寻呼消息或唤醒信号的方法、对终端设备的寻呼或唤醒方法、覆盖模式的切换方法及装置。下面结合附图，对本申请的实施例进行描述。
本申请中出现的术语“和/或”，可以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的情况，其中A，B可以是单数或者复数。另外，本申请中字符“/”，一般表示前后关联对象是一种“或”的关系。本申请中，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“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。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
为了降低终端设备的功耗，本申请提供的一些实施例涉及寻呼消息或唤醒信号的监听或发送方法。本文中的实施例涉及蜂窝通信网络，蜂窝通信网络有时在本申请中称作无线通信网络，并可以是5G通信网络、通用移动通信系统(universal mobile telecommunications system，UMTS)网络、LTE网络、宽带码分多址(wideband code division multiple access，WCDMA)网络、全球移动通讯系统(global system for mobile communications，GSM)网络或任何其它无线通信网络或系统。
图3示意性示出终端设备所执行的监听寻呼消息或唤醒信号的方法的实施例。终端设备和驻留小区的基站支持正常覆盖和扩展覆盖，换言之，终端设备可以选择在正常覆盖或扩展覆盖进行数据传输。参考图3，本申请监听寻呼消息或唤醒信号方法的一个实施例包括：
101、终端设备向接入节点发送模式偏好信息；
小区中的部分终端设备可能不支持扩展覆盖，或者虽然支持扩展覆盖，但是由于满足正常覆盖的小区选择S准则，该部分终端设备仍然按照现有技术在正常覆盖下监听寻呼消息，接入节点需要向该部分终端设备发送正常覆盖下的寻呼消息。为了便于接入节点选择适当的覆盖模式对小区中的终端设备进行寻呼，支持扩展覆盖的终端设备可以向接入节点发送模式偏好信息，该模式偏好信息用于通知接入节点该终端设备在空闲态满足正常覆盖的小区选择S准则时选择扩展覆盖，便于接入节点根据该模式偏好信息在扩展覆盖下对该终端设备进行寻呼。
在本申请一种可能的实现方式中，模式偏好信息可以携带于无线资源控制(Radio Resource Control,RRC)消息中，可选的，无线资源管理消息可以为用户设备辅助信息(UE assistance information)消息。或者，在本申请一种可能的实现方式中，该模式偏好信息可以携带于非接入层(Non-Access Stratum,NAS)消息中，示例性的，非接入层消息可以为附着请求(attach request)消息、附着完成(attach complete)消息、跟踪区更新请求(tracking area update request)消息、跟踪区更新完成(tracking area update complete)消息、服务请求(service request)消息、扩展的服务请求(extended service request)消息和控制面服务请求(control plane service request)消息中的至少一种消息。在本申请一种可能的实现方式中，终端设备可以在连接态下向接入节点发送模式偏好信息。
102、终端设备确定其满足正常覆盖的小区选择S准则；
在空闲态，终端设备的主要操作包括小区选择/重选以及监听驻留小区的寻呼消息等。在确定驻留小区前，终端设备可以确定其在候选的驻留小区中是否满足正常覆盖的小区选择S准则。在本申请实施例中，终端设备可以确定其满足正常覆盖的小区选择S准则。
103、终端设备选择扩展覆盖；
现有技术中，若终端设备满足正常覆盖的小区选择S准则，则终端设备选择正常覆盖。和现有技术不同，在本申请实施例中，在空闲态，若终端设备满足正常覆盖的小区选择S准则，终端设备选择扩展覆盖。在本申请一种可能的实现方式中，若终端设备满足扩展覆盖的小区选择S准则，终端设备可以选择扩展覆盖。也就是说，只要终端设备满足扩展覆盖的小区选择S准则，无论其是否满足正常覆盖的小区选择S准则，终端设备可以选择扩展覆盖。
104、终端设备根据扩展覆盖的系统消息从接入节点监听扩展覆盖下的寻呼消息或唤醒信号；
在一种可能的实现方式中，接入节点广播的系统消息一般携带有其发送的相应覆盖模式下的寻呼消息或唤醒信号的配置信息，也就是说，终端设备选择扩展覆盖后，需要先行接收扩展覆盖的系统消息，之后根据扩展覆盖的系统消息从驻留小区的接入节点监听寻呼消息或唤醒信号。在一种可能的实现方式中，终端设备在接收系统消息后，会对其进行存储，因此，若终端设备接收过扩展覆盖的系统消息，且未接收到扩展覆盖的系统消息发生改变的通知，则终端设备在选择扩展覆盖后，可以不执行接收扩展覆盖的系统消息的步骤，而是直接根据存储的扩展覆盖的系统消息从接入节点监听寻呼消息或唤醒信号。
在本申请一种可能的实现方式中，扩展覆盖的系统消息包括带宽减少(Bandwidth reduced,BR)版本(即窄带)上的系统消息。
在本申请一种可能的实现方式中，扩展覆盖的寻呼消息或唤醒信号包括发送于窄带上的寻呼消息或唤醒信号。
由于终端设备更多的处于正常覆盖，因此，终端设备在空闲态选择扩展覆盖，和现有技术相比，本申请实施例有利于减少终端设备在正常覆盖下的较大带宽上收发数据引起的高功耗，延长终端设备的续航时长。并且，终端设备通过向接入节点发送模式偏好信息，能够使得接入节点在扩展覆盖下寻呼该终端设备，降低接入节点寻呼终端设备的复杂度，提高寻呼效率。
接入节点接收到核心网网元发送的对终端设备的寻呼消息时，接入节点可以选择一种覆盖模式向该终端设备发送寻呼消息，若寻呼失败，可以选择其他覆盖模式向该终端设备发送寻呼消息，但是，接入节点对终端设备的寻呼时延会加长。为了减少接入节点对终端设备的寻呼时延，本申请还提供一种对终端设备的寻呼或唤醒方法，图4为本申请对终端设备的寻呼或唤醒方法的一个实施例示意图，参考图4，本申请对终端设备的寻呼或唤醒方法一个实施例包括：
201、接入节点接收终端设备发送的模式偏好信息；
若终端设备向接入节点发送模式偏好信息，该模式偏好信息用于通知该终端设备在满足正常覆盖的小区选择S准则时选择扩展覆盖，接入节点可以接收到终端设备发送的该模式偏好信息。
202、接入节点根据模式偏好信息向终端设备发送扩展覆盖下的寻呼消息或唤醒信号；
接入节点在接收到终端设备发送的模式偏好信息后，可以根据模式偏好信息在扩展覆盖下向终端设备发送寻呼消息或唤醒信号。
在图4对应的实施例中，发送模式偏好信息的终端设备在空闲态倾向于在扩展覆盖下监听寻呼消息或唤醒信号，因此，若接入节点接收到该终端设备发送的模式偏好信息，当接收到核心网网元发送的对该终端设备的寻呼消息时，接入节点按照该终端设备的模式偏好信息在扩展覆盖下向终端设备发送寻呼消息或唤醒信号，有利于减少接入节点对终端设备的寻呼时延。
由于终端设备的移动性以及接入节点发射信号的波动性，终端设备的驻留小区会发生变化，因此，在本申请监听寻呼消息或唤醒信号的方法一些实施例中，终端设备可以向每个驻留小区的接入节点均执行至少一次步骤101。或者，为了减少终端设备执行步骤101的次数，在一些实施例中，本申请对终端设备的寻呼或唤醒方法还可以包括如下步骤：
203、接入节点将模式偏好信息发送至核心网网元；
接入节点在接收到终端设备发送的模式偏好信息后，可以将接收到的模式偏好信息发送至核心网网元，比如MME。
204、接入节点接收核心网网元发送的寻呼消息和模式偏好信息；
在一种可能的实现方式中，当核心网网元，比如MME，接收到对该终端设备的下行数据通知时，可以将对该终端设备的寻呼消息和该终端设备的模式偏好信息发送给该终端设备注册的跟踪区(tracking area，TA)内的所有接入节点，比如eNB。一种可能的实现方式中，核心网网元可以将模式偏好信息携带于寻呼消息。由于终端设备的驻留小区可能发生变化，因此接收到核心网网元发送的模式偏好信息的接入节点可能与接收到终端设备发送的模式偏好信息的接入节点不同。
接入节点通过将终端设备发送的模式偏好信息发送给核心网网元，由核心网网元将其模式偏好信息通知给该终端设备的各个可能驻留的小区的接入节点，这样终端设备仅执行一次步骤101便可以将其模式偏好信息通知给各个可能驻留的小区的接入节点，有利于降低终端设备的功耗，同时可以避免接入节点保存模式偏好信息。
本申请上述各个实施例有利于实现终端设备对空闲态下覆盖模式的主动选择。在一些实施例中，本申请对终端设备的寻呼或唤醒方法还可以包括如下步骤：
205、接入节点向终端设备发送偏好准许信息；
接入节点可以向终端设备发送偏好准许信息，偏好准许信息用于指示准许终端设备在满足正常覆盖的小区选择S准则时选择扩展覆盖。在本申请一种可能的实现方式中，偏好准许信可以携带于系统消息(system information)、无线资源控制连接设置(RRC connection setup)消息、无线资源控制连接恢复(RRC connection resume)消息、无线资源控制连接重配置(RRC connection reconfiguration)消息、无线资源控制连接重建立(RRC connection Reestablishment)消息、切换命令(Hand over command)中至少一项消息中。
在本申请一些实施例中，本申请监听寻呼消息或唤醒信号的方法还可以包括如下步骤：
105、终端设备接收接入节点发送的偏好准许信息；
若接入节点向终端设备发送偏好准许信息，偏好准许信息用于指示准许终端设备在满足正常覆盖的小区选择S准则时选择扩展覆盖，终端设备可以接收接入节点发送的该偏好准许信息。在本申请一种可能的实现方式中，偏好准许信可以携带于系统消息、无线资源控制连接设置消息、无线资源控制连接恢复消息、无线资源控制连接重配置消息、无线资源控制连接重建立消息、切换命令中至少一项消息中。
在一些实施例中，接入节点可以根据接收到的终端设备的模式偏好信息向终端设备发送偏好准许信息。
在一些实施例中，向接入节点发送过模式偏好信息的终端设备，需要在接收到接入节点发送的偏好准许信息后，方能在满足正常覆盖的小区选择S准则时选择扩展覆盖。
或者，在一些实施例中，终端设备可以在接收到接入节点的偏好准许信息之后，开始执行图1对应的实施例。
图5为本申请数据传输方法一个实施例示意图，该数据传输方法中接入节点执行的各个步骤对应于本申请对终端设备的唤醒方法另一个实施例，终端设备执行的各个步骤对应于本 申请监听唤醒信号的方法另一个实施例。在图5对应的实施例中，接入节点支持唤醒信号，参考图5，本申请数据传输方法一个实施例可以包括如下步骤：
101a、终端设备向接入节点发送模式偏好信息；
203a、接入节点将模式偏好信息发送至核心网网元；
205a、接入节点向终端设备发送偏好准许信息；
102a、终端设备确定满足正常覆盖的小区选择S准则；
103a、终端设备选择扩展覆盖；
104a、终端设备根据扩展覆盖的系统消息从接入节点监听扩展覆盖下的唤醒信号；
204a、接入节点接收核心网网元发送的寻呼消息和模式偏好信息；
202a、接入节点根据模式偏好信息向终端设备发送扩展覆盖下的唤醒信号。
图5对应的实施例中的各个步骤可以参考前述对应步骤的描述，此处不再赘述。比如，步骤101a可以参考前述对步骤101的相关描述，步骤203a可以参考前述对步骤203的相关描述。
和现有技术相比，通过上述实施例，终端设备能够以更小的功耗接收寻呼消息或唤醒信号。在一些实施例中，当终端设备有上行数据需要发送时，或者，当终端设备监听到扩展模式下的寻呼消息或唤醒信号时，若终端设备仍然满足正常覆盖的小区选择S准则，终端设备一般需要进行覆盖模式的切换，以在正常覆盖下与接入节点进行数据传输。
现有技术中，若终端设备在第一覆盖模式下有上行数据需要发送或者接收到寻呼消息或唤醒信号，但是需要切换至第二覆盖模式下与接入节点在连接态进行数据传输，则终端设备需要在和接入节点建立通信连接之后进行覆盖模式的切换，具体的，参考图6，现有技术中覆盖模式的切换方法可以包括如下步骤：
301、在空闲态，当终端设备有上行数据需要发送时，或者，当终端设备监听到第一覆盖模式下的寻呼消息或唤醒信号时，终端设备根据第一覆盖模式下的系统消息向接入节点发起连接建立请求；
当第一覆盖模式为扩展覆盖时，若接入节点支持唤醒信号，那么终端设备可以监听扩展覆盖下的唤醒信号，之后监听扩展覆盖下的寻呼消息，在接收到扩展覆盖下的寻呼消息后，终端设备可以根据扩展覆盖下的系统消息向接入节点发起连接建立请求。
302、若终端设备与接入节点建立通信连接，则终端设备接收接入节点发送的在第一覆盖模式下的模式切换指令；
303、终端设备由当前的第一覆盖模式切换为第二覆盖模式。
第一覆盖模式与第二覆盖模式不同，比如，第一覆盖模式可以为扩展覆盖，第二覆盖模式为正常覆盖，或者，第一覆盖模式可以为正常覆盖，第二覆盖模式为扩展覆盖。
通过图6对应的覆盖模式的切换过程不难看出，现有技术需要利用专用模式切换指令在连接态来实现覆盖模式的切换，浪费信道资源。为了节约信道资源，本申请提供一种覆盖模式的切换方法，参考图7，本申请覆盖模式的切换方法一个实施例包括：
401、当终端设备有上行数据需要发送时，或者，当终端设备监听到第一覆盖模式下的寻呼消息或唤醒信号时，终端设备由当前的第一覆盖模式切换为第二覆盖模式；
在空闲态，终端设备在完成小区选择/重选，并选择驻留小区的覆盖模式后，可以在所选 的覆盖模式下监听驻留小区的寻呼消息或唤醒信号，为了便于描述，将终端设备在空闲态选择的覆盖模式称作第一覆盖模式。当终端设备有上行数据需要发送时，或者，当终端设备监听到第一覆盖模式下的寻呼消息或唤醒信号时，终端设备可以由当前的第一覆盖模式切换为第二覆盖模式。第一覆盖模式与第二覆盖模式不同，比如，第一覆盖模式可以为扩展覆盖，第二覆盖模式为正常覆盖，或者，第一覆盖模式可以为正常覆盖，第二覆盖模式为扩展覆盖。
在一种可能的实现方式中，寻呼消息或唤醒信号中携带有模式切换指示，该模式切换指示用于指示该终端设备在接收到寻呼消息或唤醒信号时将覆盖模式设置为第二覆盖模式，或者指示终端设备在接收到寻呼消息或唤醒信号时进行覆盖模式的切换，在第二覆盖模式下发起连接建立请求。终端设备在接收到寻呼消息或唤醒信号时，可以根据其携带的模式切换指示，由当前的第一覆盖模式切换为第二覆盖模式。
402、终端设备根据第二覆盖模式下的系统消息，在第二覆盖模式下向接入节点发起连接建立请求。
接入节点广播的系统消息一般携带有其发送的相应覆盖模式下的寻呼消息或唤醒信号的配置信息。在一种可能的实现方式中，终端设备切换至第二覆盖模式后，需要先行接收第二覆盖模式的系统消息，之后根据第二覆盖模式的系统消息，在第二覆盖模式下向接入节点发起连接建立请求。在一种可能的实现方式中，终端设备在接收到系统消息后，会对其进行存储，因此，若终端设备接收过第二覆盖模式的系统消息，且未接收到第二覆盖模式的系统消息发生改变的通知，则终端设备在切换至第二覆盖模式后，可以不执行接收第二覆盖模式的系统消息的步骤，而是直接根据存储的第二覆盖模式的系统消息，在第二覆盖模式下向接入节点发起连接建立请求，接入节点可以在第二覆盖模式下接收到终端设备发送的连接建立请求。
和现有技术相比，本申请提供的覆盖模式的切换方法，可以节省使用专用信令来切换覆盖模式的信令开销，有利于节约接入节点与终端设备间的信令，进而节约信道资源。
需要说明的是，由于目前只有扩展覆盖可能支持唤醒信号，因此，步骤401中，若终端设备监听到第一覆盖模式下的唤醒信号，那么表明第一覆盖模式为扩展覆盖，并且，由于终端设备在第一覆盖模式下监听到唤醒信号之后会切换为第二覆盖模式，因此，终端设备可以在第二覆盖模式下监听寻呼消息，当监听到第二覆盖模式下的寻呼消息时，终端设备可以触发步骤402。步骤401中，若终端设备监听到第一覆盖模式下的寻呼消息，那么可能包括以下两种情况：1)终端设备未监听到唤醒信号，比如第一覆盖模式为正常覆盖，或者，虽然第一覆盖模式为扩展覆盖，但是接入节点不支持唤醒信号；2)终端设备已经在第一覆盖模式下监听到唤醒信号，第一覆盖模式为扩展覆盖，在监听到唤醒信号后，终端设备继续在第一覆盖模式下监听寻呼消息。
本申请还提供接入节点侧的一种覆盖模式的切换方法，参考图8，本申请覆盖模式的切换方法另一个实施例可以包括如下步骤：
501、接入节点向终端设备发送第一覆盖模式下的寻呼消息或唤醒信号；
接入节点接收到核心网网无发送的对终端设备的寻呼消息时，可以在第一覆盖模式下向该终端设备发送寻呼消息或唤醒信号。在一种可能的实现方式中，寻呼消息或唤醒信号中携带有模式切换指示，该模式切换指示用于指示该终端设备在接收到寻呼消息或唤醒信号时将 覆盖模式设置为第二覆盖模式，或者指示终端设备在接收到寻呼消息或唤醒信号时进行覆盖模式的切换，在第二覆盖模式下发起连接建立请求。
在本申请一些实施例中，接入节点可以根据终端设备的网络状况或待传输的下行数据的类型来决定是否在寻呼消息或唤醒信号中加入模式切换指示。示例性的，若待传输的下行数据的数据量较大，或者对传输时延的要求较高，那么接入节点可以在寻呼消息或唤醒信号中加入模式切换指示。在一种可能的实现方式中，待传输的下行数据的类型可以为核心网网元发送给接入节点的。
502、接入节点接收该终端设备发送的第二覆盖模式下的连接建立请求。
接入节点在第一覆盖模式下向该终端设备发送寻呼消息或唤醒信号之后，可以在第二覆盖模式下接收该终端设备发送的连接建立请求。
本申请接入节点侧的覆盖模式的切换方法一些实施例还可以包括如下步骤：
503、接入节点广播第一覆盖模式下的包括模式切换准许指示的系统消息；
接入节点广播的第一覆盖模式的系统消息中可以携带模式切换准许指示，用于指示准许在本小区驻留的终端设备在空闲态有上行数据需要发送或者监听到第一覆盖模式下的寻呼消息或唤醒信号时，由第一覆盖模式切换为第二覆盖模式。
本申请终端设备侧的覆盖模式的切换方法一些实施例中，若终端设备接收到的第一覆盖模式的系统消息携带有模式切换准许指示，在空闲态，当终端设备有上行数据需要发送时，或者，当终端设备监听到第一覆盖模式下的寻呼消息或唤醒信号时，终端设备可以根据模式切换准许指示由当前的第一覆盖模式切换为第二覆盖模式。或者，本申请终端设备侧的覆盖模式的切换方法一些实施例中，在空闲态，当终端设备有上行数据需要发送时，或者，当终端设备监听到第一覆盖模式下的寻呼消息或唤醒信号时，终端设备可以判断自身设备是否满足第二覆盖模式的小区选择S准则，若终端设备满足第二覆盖模式的小区选择S准则，则终端设备可以执行由当前的第一覆盖模式切换为第二覆盖模式的步骤。或者，在本申请一些实施例中，在空闲态，当终端设备有上行数据需要发送时，或者，当终端设备监听到第一覆盖模式下的寻呼消息或唤醒信号时，若终端设备接收到的第一覆盖模式的系统消息携带有模式切换准许指示，并且终端设备满足第二覆盖模式的小区选择S准则，那么终端设备可以由当前的第一覆盖模式切换为第二覆盖模式。
若接入节点需要修改广播的系统消息，接入节点一般在寻呼消息中加入系统消息的修改通知，以通知驻留在本小区的终端设备系统消息发生改变，终端设备在接收到携带有修改通知的寻呼消息后，可以接收改变后的系统消息，以根据改变后的系统消息向接入节点发起连接建立请求。现有技术中，修改通知携带于与发生改变的系统消息相同的覆盖模式下的寻呼消息中，也就是说，第一覆盖模式下的系统消息的修改通知携带于第一覆盖模式的寻呼消息中，第二覆盖模式下的系统消息的修改通知携带于第二覆盖模式的寻呼消息中。
但是，若终端设备在监听到第一覆盖模式的寻呼消息时，切换为第二覆盖模式，并根据第二覆盖模式下的系统消息在第二覆盖模式下向接入节点发起连接建立请求，那么，按照现有技术提供的系统消息改变的通知方法，终端设备在监听到第一覆盖模式的寻呼消息时，将无法及时获知第二覆盖模式下的系统消息发生改变，因此也无法根据改变后的第二覆盖模式下的系统消息在第二覆盖模式下向接入节点发起连接建立请求。
为了使得终端设备在监听到第一覆盖模式的寻呼消息时，能够及时获取改变后的第二覆盖模式下的系统消息，以根据改变后的第二覆盖模式下的系统消息在第二覆盖模式下向接入节点发起连接建立请求，在本申请接入节点侧的覆盖模式的切换方法一些实施例中，若第二覆盖模式下的系统消息发生改变，接入节点可以向终端设备发送第一覆盖模式下的携带第一修改通知的寻呼消息，第一修改通知用于通知终端设备第二覆盖模式下的系统消息发生改变。本申请终端设备侧的覆盖模式的切换方法一些实施例还可以包括如下步骤：
403、终端设备根据第一修改通知接收改变后的第二覆盖模式下的系统消息；
当终端设备监听到第一覆盖模式下的寻呼消息时，若该寻呼消息中携带第一修改通知，第一修改通知用于通知第二覆盖模式下的系统消息发生改变，那么终端设备可以根据该第一修改通知接收改变后的第二覆盖模式下的系统消息，比如，终端设备可以在第二覆盖模式下向接入节点发起连接建立请求之前接收改变后的第二覆盖模式下的系统消息。
在本申请一些实施例中，若步骤401中终端设备监听到第一覆盖模式下的唤醒信号，本申请覆盖模式的切换方法还可以包括如下步骤：
404、终端设备接收第二覆盖模式下的寻呼消息；
若接入节点支持唤醒信号，那么终端设备在驻留小区选择第一覆盖模式之后，终端设备可以监听第一覆盖模式下的唤醒信号，当终端设备监听到第一覆盖模式下的唤醒信号时，终端设备可以由当前的第一覆盖模式切换第二覆盖模式，并接收第二覆盖模式下的寻呼消息。
若终端设备在监听到第一覆盖模式的唤醒信号后，切换为第二覆盖模式，并根据第二覆盖模式下的系统消息监听第二覆盖模式的寻呼消息，那么，按照现有技术提供的系统消息改变的通知方法，终端设备在监听到第二覆盖模式的寻呼消息时，将无法及时获知第一覆盖模式下的系统消息发生改变，因此之后也无法根据改变后的第一覆盖模式下的系统消息监听第一覆盖模式下的唤醒信号。为了使得终端设备在监听到第二覆盖模式的寻呼消息时，能够及时获取改变后的第一覆盖模式下的系统消息，以根据改变后的第一覆盖模式下的系统消息监听第一覆盖模式下的唤醒信号，本申请覆盖模式的切换方法一些实施例还可以包括如下步骤：
405、终端设备根据寻呼消息中的第二修改通知接收改变后的第一覆盖模式下的系统消息。
若第二覆盖模式下的寻呼消息携带第二修改通知，第二修改通知用于指示第一覆盖模式下的系统消息发生改变，则终端设备可以根据第二修改通知接收改变后的第一覆盖模式下的系统消息，比如，可以在下一次监听第一覆盖模式下的唤醒信号之前执行步骤405。
在本申请覆盖模式的切换方法一些实施例中，第一覆盖模式为扩展覆盖，第二覆盖模式为正常覆盖。本申请终端设备侧的覆盖模式的切换方法一些实施例还可以包括前述本申请监听寻呼消息或唤醒信号的方法任一实施例的步骤，本申请接入节点侧的覆盖模式的切换方法一些实施例还可以包括前述本申请对终端设备的寻呼或唤醒方法任一实施例的步骤，关于本申请监听寻呼消息或唤醒信号的方法和对终端设备的寻呼或唤醒方法的具体步骤以及步骤描述，可以参考前述相应实施例及其描述内容，此处不再赘述。
