本申请基于申请号为202110677352.0、申请日为2021年06月18日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种信号状态显示方法、终端及可读存储介质。
背景技术
当前5G网络发展迅速，基于NSA(Non-Standalone，非独立组网)架构的5G网络由于成本优势和架构简单等原因已经开始商用。NSA架构采用双连接方案，即终端可以同时接入LTE(Long Term Evolution，长期演进)核心网+NR(New Radio，新空口)接入网。在终端具体接入NR接入网的过程中，主要表现在终端先接入到具备NR重配能力的LTE小区，然后LTE小区通过RRC(Radio Resource Control，无线资源控制)重配消息为终端加上NR接入网的连接。
终端在双连接过程中，根据LTE小区的RRC重配消息测量5G信号，当能测量到5G信号时，终端发起5G网络注册并显示5G信号图标，否则显示4G信号图标。上述过程中，终端在接入阶段能够显示当前接入4G信号还是5G信号，但是显示时间不够长久，例如终端接入了5G网络，如果没有持续的业务，终端所在的LTE制式处于闲置状态，网络会下发RRC Release消息释放网络资源，从而导致5G制式也处于去激活状态，不能实时检测5G信号，无法判断终端的当前区域是否还处于5G信号覆盖区域，只能显示4G信号，显然并不符合实际情况。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本公开，并不用于限定本公开。
随着5G网络的发展，对于5G的网络架构，3GPP提出了多个组网架构选项，这些组网架构选项分为独立组网(Standalone，SA)和非独立组网(Non-Standalone，NSA)，其中，NSA的组网架构的5G网络由于成本优势和架构简单等原因已经开始商用。NSA架构采用双连接方案，即LTE核心网+NR接入网，用户终端(User Equipment，UE)同时接入到LTE网络和5G网络。当然，NSA架构的组网也有好几种，其中应用最为广泛的组网架构中，UE的控制面走LTE核心网，用户面走NR接入网，本公开实施例以上述这种应用最为广泛的NSA组网架构为基础进行说明。
UE在双连接过程中，主要表现在UE首先接入到具备将UE重配到NR接入网能力的LTE小区，该LTE小区通过RRC重配将NR接入网加到UE的连接中。一般来说，为了方便区分这种具备重配到NR接入网能力的LTE小区称为锚点小区，对应的不具备重配到NR接入网能力的LTE小区，则称为非锚点小区，而这种能将UE从锚点小区重配到NR接入网的能力，叫做ENDC(Dual Connectivity of E-UTRA with NR)能力。可以理解的是，锚点小区并非协议标准中提供的名词，协议中对于NSA组网下的双连接技术，要求LTE小区提供一个锚点，为当前具备5G接入能力的UE提供接入到NR接入网的支撑点，该点一般是设定LTE小区中的某个频点，通过该锚点频点，UE根据频点转换接入到到NR接入网。
在ENDC接入过程中，UE需要根据LTE小区的RRC重配信息测量5G信号，当UE能测量到5G信号时，UE才发起5G注册，显示5G网络对应的信号状态；当UE测量不到5G信号时，就代表UE周围没有5G信号，只能停留在锚点小区，处于LTE接入状态，显示LTE网络对应的信号状态。
当UE接入NR接入网后如果没有持续的业务，网络下发RRC Release释放网络资源，UE将会进入空闲态(idle)，此时5G连接也随之释放，此时即使UE还处于5G网络的覆盖范围内，UE上也只能显示LTE网络对应的信号状态，显然无法为用户准确表示5G覆盖范围。
基于此，本公开实施例提供了一种信号状态显示方法、终端及可读存储介质，针对UE处于空闲态无法准确表示当前网络覆盖情况的问题，提供了两种空闲态下的测量手段，通过测量结果来确定当前的网络覆盖情况并持续显示对应的信号状态，防止UE重新进入空闲态后再次更改所显示的信号状态。
参照图1，本公开实施例提供了一种信号状态显示方法，应用于UE，UE双连接到第一制式网络和第二制式网络，第一制式网络为UE提供接入第二制式网络的锚点频点，信号状态显示方法包括但不限于以下步骤S100、步骤S200、步骤S300和步骤S400。
步骤S100，在UE处于空闲态的情况下，监测UE在当前小区的第一制式网络的信号变化值。
步骤S200，当信号变化值大于预设信号阈值，触发接入请求以使UE与第一制式网络建立连接。
步骤S300，当通过第一制式网络的锚点频点接入第二制式网络，更新当前信号状态为第二制式网络对应的信号状态。
步骤S400，持续显示更新后的信号状态，直到下一次更新信号状态。
相关技术下，当UE在LTE小区完成随机接入过程或者进行持续的业务，那么UE进入连接态，在连接态下，UE和LTE小区对应的基站之间已经建立了RRC连接，并保存有UE的RRC上下文，在连接态下的UE可执行捕获系统消息、测量和测量上报、与网络之间进行数据的接收和发送、监听控制信道等；当UE后续在该LTE小区驻留，并断开业务连接一段时间，网络则主动向UE发送RRC Release释放网络资源，处于空闲态的UE，在基站上并没有RCC的上下文而在移动管理实体(Mobility Management Entity，MME)中存在上下文，与基站之间不存在RCC连接。空闲态下的UE可执行接收系统信息广播、监听寻呼信道、小区重选等。
为方便表述，本公开实施例中以第一制式网络为LTE网络、第二制式网络为5G网络为例。为了准确表示5G网络的覆盖信号，UE在空闲态下对LTE网络的信号值的监测，当监测得到的信号变化值大于预设信号阈值，则认为UE已经移动了一段范围，有可能已经超出或者进入5G信号的覆盖范围内，因此，由UE向LTE网络发起接入请求，确定该LTE小区是锚点小区的前提下，UE尝试进行双连接。当成功连接到5G网络，则将UE当前显示的信号状态更新为5G网络对应的信号状态。由于发起了接入请求，此时UE已经从空闲态转换到连接态，为了避免之后UE从连接态切换到空闲态时将5G网络对应的信号状态自动改成LTE网络对应的信号状态，本公开实施例将持续显示5G网络对应的信号状态，直到下一次通过信号测量等方式来更新信号状态。可以理解的是，LTE网络对应的信号状态可 以是4G图标、LTE图标等，而5G网络对应的信号状态可以是5G图标、NR图标等，本公开不对图标的样式做限定。
通过上述方式，即使UE在后续从连接态切换到空闲态，只要LTE的信号变化值没有超过预设信号阈值，都可以认为UE还处于5G网络的覆盖范围内，从而为用户提供准确的5G信号覆盖提示。
可以理解的是，即使UE触发接入请求与锚点小区建立连接，但并不一定就能够通过锚点频点连接到5G网络，因为5G信号的覆盖范围往往比4G信号的覆盖范围要小，当UE处于LTE网络的覆盖范围内且不在NR接入网的覆盖范围内时，UE进行双连接的过程中无法测量到5G信号，那么UE也只能显示LTE网络对应的信号状态，即当通过第一制式网络的锚点频点接入第二制式网络失败，更新当前信号状态为第一制式网络对应的信号状态。
关于锚点小区的判断，目前通用的方法是根据LTE小区下发的SIB2消息中是否包含“upperLayerIndication-r15”字段来判断当前LTE小区是否是锚点小区。但该字段并不是协议规定网络必须广播的，有些设备商提供的网络就不显示这个字段，并且也不一定按照这个字段来指示锚点小区。因此为了判断当前LTE小区是否为锚点小区，本公开实施例提供了一种锚点小区的判断方法，具体可以通过以下步骤实现，参照图2：
步骤S501，接收第一制式网络下发的系统消息；
步骤S502，当系统消息中包含有NSA能力指示字段，根据NSA能力指示字段判断第一制式网络是否提供锚点频点；
步骤S503，当系统消息中不包含有NSA能力指示字段，根据是否接收到第一制式网络下发的测量事件或重配消息，确定判断第一制式网络是否提供锚点频点。
在当前常用协议标准下，LTE的系统消息包括MIB、SIB1、SIB2等等，SIB2消息通常包含用来判断某小区是否适合用于小区选择的参数，以及其他时域调度信息等，根据当前3GPP协议定义的upperLayerIndication-r15字段，以“true”值来表示当前LTE小区支持ENDC功能。当然，upperLayerIndication-r15字段并非强制规定，在按照其他协议的情况下，该upperLayerIndication-r15字段不存在，或者以其他字段表示，因此步骤S501和步骤S502概括性地说明通过LTE小区下发的系统消息中的NSA能力指示字段，UE能够知道当前LTE小区是锚点小区；如果系统消息中没有任何NSA能力指示字段，那么具备ENDC能力的LTE小区仍可以将UE重配到5G网络，当UE被重配到5G网络，显然需要对5G信号进行测量来确定信号强度；那么从这一过程入手，当UE接收到LTE小区的测量事件或重配消息，则表面该LTE小区是锚点小区。可以理解的是，LTE测量事件包括很多种，通常采用3GPP协议TS38.331中的B1事件。另一方面，在UE接收到RRC重配消息的时候， 也能表示当前LTE小区是锚点小区。
可以理解的是，锚点小区的判断过程不但可以应用于空闲态的UE，在UE随机接入LTE网络的过程中，也可以通过上述步骤S501至步骤S503来判断锚点小区。
上述步骤S100和步骤S200实际表示了，显示第二制式网络对应的信号状态的依据是UE当前是否还在5G信号覆盖区域，因此根据UE测量到的LTE信号变化值的大小来判断终端移动的范围。具体来说，参照图3，步骤S100中对信号变化值的监测可以通过以下步骤实现：
步骤S110，根据预设监测时间间隔先后获取UE在当前小区的第一制式网络下的第一信号强度和第二信号强度；
步骤S120，根据第一信号强度和第二信号强度确定信号变化值。
UE在空闲态状态下，可以持续测量LTE信号的信号强度，一般来说，UE固定在一个位置附近不移动的情况下，测量得到的LTE信号强度不会大幅度变化，当UE移动超过一定范围的时候，测量得到的LTE信号强度才可能发生大幅度变化，那么这个变化幅度超过预设信号阈值，才触发接入请求。在这过程中，UE以预设时间间隔先后测量得到第一信号强度和第二信号强度，从而根据第一信号强度和第二信号强度计算得到信号变化值。值得注意的是，对于UE缓慢移动而使得LTE信号强度缓慢变化的情况，UE可以考虑在多个连续时间间隔之间测量的前后两个信号值，来计算得到信号变化值。
在一些情况下，UE移动使得UE脱离了当前的LTE小区，那么在判断信号变化值之前，还需要判断UE是否还处于同一个LTE小区，因此上述步骤S110中获取第一信号值和第二信号值后，参照图4，具体还要做以下步骤的判断：
步骤S111，确定第一信号强度对应的第一小区标识号和第二信号强度对应的第二小区标识号；
步骤S112，当第一小区标识号和第二小区标识号不相同，向第二小区标识号对应的小区发送随机接入请求。
通常来说，通过LTE小区的小区ID来判断UE是否还处于同一个LTE小区，当LTE小区的小区ID发生变化，则表明UE已经移动出前一个LTE小区而进入到后一个LTE小区。从前后两次信号测量结果来看，两次信号强度测量都可以确定UE当前处于哪个LTE小区，一旦前后两次测量得到的小区ID不相同，则需要重新判断后一个LTE小区是否为锚点小区，再执行后续的双连接过程。
参照图5，上述步骤S200中触发接入请求可以通过以下步骤实现：
步骤S210，向当前小区发送接入请求，接入请求为数据业务请求或随机接入请求；
步骤S220，触发与第一制式网络的无线资源控制RRC连接。
当UE监测信号变化值超过预设信号阈值，此时UE触发一个业务，与第一制式网络建立RRC连接，在建立RRC连接之后才可以通过第一制式网络尝试连接到第二制式网络。可以理解的是，触发建立RRC连接的方式有多种，例如，UE可以自生成一个数据业务来触发RRC连接，也可以是触发随机接入业务来触发RRC连接。
除了上述通过信号强度的变化值来测量5G信号覆盖范围，还可以通过基站侧定期发送寻呼消息来测量5G信号覆盖范围。
参照图6，本公开实施例还提供了一种信号状态显示方法，应用于UE，UE双连接到第一制式网络和第二制式网络，第一制式网络为UE提供接入第二制式网络的锚点频点，信号状态显示方法包括但不限于以下步骤S600、步骤S700、步骤S800和步骤S900。
步骤S600，在UE处于空闲态的情况下，接收周期性发送的寻呼消息；
步骤S700，当接收到寻呼消息，触发接入请求以使UE与第一制式网络建立连接；
步骤S800，当通过第一制式网络的锚点频点接入第二制式网络，更新当前信号状态为第二制式网络对应的信号状态；
步骤S900，持续显示更新后的信号状态，直到下一次更新信号状态。
在本实施例中，基站侧定期发送寻呼消息来触发UE的接入请求。当UE处于空闲态并接收到基站发送的该寻呼消息，UE自动触发接入请求来连接到第一制式网络，如果通过该第一制式网络成功重配到第二制式网络，则可以更新当前信号状态为第二制式网络对应的信号状态。信号显示过程与上一实施例的方式相同，在此不再展开说明。
同样地，当通过第一制式网络的锚点频点接入第二制式网络失败，更新当前信号状态为第一制式网络对应的信号状态。
可以理解的是，UE在接收到寻呼消息之后，发起接入请求之前，仍然需要判断UE是否还处于当前的LTE小区，具体可以通过以下步骤实现，参照图7：
步骤S710，确定接收寻呼消息前后UE所在小区的第三小区标识号和第四小区标识号；
步骤S720，当第三小区标识号和第四小区标识号不相同，向第四小区标识号对应的小区发送随机接入请求。
采用寻呼消息来触发接入请求的方案下，UE测量LTE小区的小区ID，当接收到寻呼消息，则确定接收寻呼消息前后的两个小区ID，从而确定LTE小区是否发生了变化。如果测量得到的LTE小区的小区ID发生了变化，则UE需要重新接入到后一个LTE小区，因此触发发起随机接入过程。
同理，上述接入请求也可以通过不同的方式触发RRC连接，参照图8，具体如下步骤：
步骤S730，向当前小区发送接入请求，接入请求为数据业务请求或随机接入请求；
步骤S740，触发与第一制式网络的无线资源控制RRC连接。
通过上述两个实施例，针对在NSA架构下，双连接的用户终端上两种网络制式的信号状态显示不准确的问题，提供了在用户终端空闲态下无法监测网络信号状态的解决办法，当用户终端从连接态转换到空闲态，或者当前处于空闲态(与当前网络断开连接)下，对第一制式网络的信号进行监测，或者接收第一制式网络定期发送的寻呼消息，自动触发接入请求，从而用户终端可以尝试进行双连接，当成功通过LTE网络连接到5G网络，则用户终端持续显示5G网络对应的信号状态，当连接5G网络失败，则用户终端持续显示LTE网络对应的信号状态，此信号状态持续显示到下一次更新；通过这一方式，解决了用户终端处于空闲态下，即使用户终端位于5G网络的覆盖范围却无法显示5G网络对应的信号状态的问题，从而能够更加准确地判断5G覆盖区域。
下面以实际三个示例对本公开实施例的信号状态显示方法进行说明：
示例一
本示例提供了一种在NSA网络中UE显示5G信号状态的终端装置，如图9所示，终端装置200包括：
锚点小区判断模块201，根据UE所注册的LTE小区是否下发NR重配消息或者NR测量事件信息，判断当前LTE小区是否是锚点小区；
LTE信号监测模块202，该模块只在锚点小区运行，当UE在锚点小区中LTE信号变化值超过预设信号阈值时，发送消息给业务触发模块204，同时该模块还监测LTE小区的小区ID是否发生了变化，如果LTE小区的小区ID发生变化，则需要通知锚点小区判断模块201判断变化后的小区是否是锚点小区；
寻呼信息接收模块203，该模块只在锚点小区运行，当接收到LTE网络发送的寻呼消息时，发送消息给业务触发模块204；
业务触发模块204，根据LTE信号监测模块202或者寻呼信息接收模块203发来的消息，触发一次业务，使UE发起RRC Connect Request，进而执行NR信号测量以及尝试接入NR接入网；
5G区域判断模块205，根据业务触发模块204执行过程中测量的NR信号以及接入NR接入网的成功与否，判断当前位置是否是5G信号的覆盖区域；
5G显示判断模块206，根据5G区域判断模块上报的结果以及5G显示需求，判断当前是否在UE上显示5G；有些UE的信号显示需求是要求终端只要进入锚点小区就显示5G图标，有些UE的信号显示需求会要求UE必须进入5G信号覆盖区域才能显示5G图标；
显示模块207，根据5G显示判断模块206的信息上报，更新显示当前的制式信息(5G或者4G)，该显示状态一直保持到“5G显示判断模块206”下次信息上报，也就是说当前显示的制式信息(5G或者4G)是“5G显示判断模块206”上一次判断的结果，在两次判断结果时间间隔之内，显示模块207不更新显示的制式信息(4G或者5G)。
示例二
本示例提供了一种应用示例一装置200的信号状态的显示方法，其方法流程参照图10所示，包括以下步骤：
步骤S301：开始流程；
步骤S302：UE开机接入LTE小区；
步骤S303：UE在该小区中判断网络是否下发了NR测量事件(比如3GPP协议中TS38.331中的B1事件)消息或者NR重配消息。该步骤由装置200中的锚点小区判断模块201来执行；
步骤S304：当步骤S303判断该小区下发了NR重配信息或者NR测量事件时，判断当前小区是锚点小区；
步骤S305：在锚点小区尝试接入5G是否成功。该步骤由装置200中的5G区域判断模块205来执行；
步骤S306：当接入5G成功时，则更新制式图标显示为5G。该步骤由装置200中的5G显示判断模块206和显示模块207执行；

本公开实施例提供的信号状态显示方法，至少具有如下有益效果：本公开实施例针对在NSA架构下，双连接的用户终端上两种网络制式的信号状态显示不准确的问题，提供了在用户终端空闲态下无法监测网络信号状态的解决办法，当用户终端从连接态转换到空闲态，或者当前处于空闲态(与当前网络断开连接)下，对第一制式网络的信号进行监测， 或者接收第一制式网络定期发送的寻呼消息，自动触发接入请求，从而用户终端可以尝试进行双连接，当成功通过LTE网络连接到5G网络，则用户终端持续显示5G网络对应的信号状态，当连接5G网络失败，则用户终端持续显示LTE网络对应的信号状态，此信号状态持续显示到下一次更新；通过这一方式，解决了用户终端处于空闲态下，即使用户终端位于5G网络的覆盖范围却无法显示5G网络对应的信号状态的问题，从而能够更加准确地判断5G覆盖区域。
