背景技术
目前，各家运营商都比较关注新空口承载语音业务(Voice over New Radio，简称VoNR)用户的体验，因此基站对于这类用户有一套保障策略。在生效保障策略时，需要先识别出用户为VoNR用户，通常的方法是等用户建立业务后，根据该用户是否携带的5QI1/5QI2承载来识别用户是否为VoNR用户。然而，一些保障策略在用户接入阶段就需要识别出该用户是否为VoNR用户。
在相关技术中，协议已经支持在非激活态(Inactive)用户的连接恢复(Resume)阶段，通过随机接入信息3(又称为MSG3)的无线资源控制连接恢复请求原因值可识别出主叫用户是否为VoNR用户。但是，对于被叫用户是否为VoNR用户无法进行识别，导致基站无法针对被叫用户来优选运行保障策略。

具体实施方式
为使本领域的技术人员更好地理解本申请的技术方案，下面结合附图对本申请提供的一种新空口承载语音业务用户识别方法、基站和计算机可读介质进行详细描述。
在下文中将参考附图更充分地描述示例实施例，但是所述示例实施例可以以不同形式来体现且不应当被解释为限于本文阐述的实施例。反之，提供这些实施例的目的在于使本申请透彻和完整，并将使本领域技术人员充分理解本申请的范围。
本文所使用的术语仅用于描述特定实施例，且不意欲限制本申请。如本文所使用的，单数形式“一个”和“该”也意欲包括复数形式，除非上下文另外清楚指出。还将理解的是，当本说明书中使用术语“包括”和/或“由……制成”时，指定存在特征、整体、步骤、操作、元件和/或组件，但不排除存在或添加一个或多个其他特征、整体、步骤、操作、元件、组件和/或其群组。
本申请的技术方案应用于VoNR业务中，能够对处于Inactive态的被叫用户是否为VoNR用户进行有效识别，以便于基站针对不同类型的用户端，采取不同的接纳或服务质量(Quality of Service，简称QoS)策略，从而能够在最大化利用运营商系统容量的同时，提升用户体验。
为便于本领域技术人员理解本申请的技术方案，下面对相关技术中主叫终端与被叫端建立语音通话过程进行详细描述。首先，主叫端发起随机接入，以与周围的一个基站恢复无线资源控制(Radio Resource Control， 简称RRC)连接，主叫端由非激活态(Inactive)切换为激活态(Active)。接着，与主叫端建立RRC连接的基站向被叫端当前所属基站发送针对新空口承载语音业务的寻呼信息，被叫端当前所属基站接收到该寻呼信息后触发无线接入网(Radio Access Network，简称RAN)寻呼流程，被叫端当前所属基站向被叫端发送RAN寻呼，被叫端响应该RAN寻呼触发RRC连接恢复流程；被叫端发起随机接入，以与周围的一个基站恢复RRC连接。此时，主叫端和被叫端之间可进行高清通话。
需要说明的是，下述实施例中的用户端均是指“被叫端”。
图1为本申请实施例提供的一种新空口承载语音业务用户识别方法的流程图，该方法的执行主体为基站，包括：
步骤S1、响应于接收到用户端发送的无线资源控制连接恢复请求，从无线资源控制连接恢复请求中提取出用户端的身份标识。
基站接收到用户端发送的无线资源控制连接恢复请求后，从该无线资源控制连接恢复请求中提取出用户端的身份标识。
在一些实施例中，身份标识为非激活态-无线网络临时标识(Inactive-Radio Network Temporary Identity，简称I-RNTI)。
在实际应用中，根据用户端的设备类型不同，发送的无线资源控制连接恢复请求可能为RRCResumeRequest或RRCResumeRequest1；其中RRCResumeRequest内的I-RNTI(也称为short I-RNTI)为24比特，RRCResumeRequest1内的I-RNTI为40比特。
步骤S2、查询预先配置的数据库中是否存储有用户端的身份标识。
其中，数据库中存储有若干个身份标识及其对应的存储写入时刻。
在步骤S2中，当查询出数据库中存储有用户端的身份标识时，则执行步骤S3；当查询出数据库中未存储有用户端的身份标识时，则执行步骤S6。
步骤S3、计算接收到无线资源控制连接恢复请求的接收时刻与数据库中用户端的身份标识所对应的存储写入时刻的时间差。
步骤S4、判断时间差是否小于预定义的有效时长阈值。
当判断出时间差小于有效时长阈值时，则执行步骤S5；当判断出时间差大于或等于有效时长阈值时，则执行步骤S6。
步骤S5、识别出用户端为新空口承载语音业务用户。
步骤S6、识别出用户端不为新空口承载语音业务用户。
图2为本申请实施例提供的另一种新空口承载语音业务用户识别方法的流程图，该方法的执行主体为基站，该方法不但包括上述步骤S1～步骤S6，还包括步骤S01和步骤S02，下面仅对步骤S01和步骤S02进行详细描述。
步骤S01、响应于新空口承载语音业务触发无线接入网寻呼流程，为无线接入网寻呼信息配置预定义标识。
基站在被触发RAN寻呼流程时，会检测该RAN寻呼流程是否是由VoNR业务相关信令所触发。具体地，当检测出该RAN寻呼流程是由5QI5(一种5G QoS标识符)的服务质量流(QoS Flow)的核心网数据达到所触发，或由核心网下发的数据连接(PDU Session)修改请求消息请求建立5QI1或5QI2的QoS Flow的信令所触发时，则确定出该RAN寻呼流程是由VoNR业务相关信令所触发，此时执行步骤S01；反之，则确定出该RAN寻呼流程不是由VoNR业务相关信令所触发.
步骤S02、将配置有预定义标识的无线接入网寻呼信息发送至同一基站内的分布单元以及其他相邻基站。
需要说明的是，被叫端所属基站在想其他相邻基站发送RAN寻呼信息的同时，也会向被叫端发送RAN寻呼，以供被叫端响应该RAN寻呼而触发RRC连接恢复流程。
本申请的技术方案对步骤S01～步骤S02与步骤S1～步骤S6的执行顺序不作限定。即步骤S01～步骤S02可以位于步骤S1～步骤S6之前执行，或之后执行，或两者同步执行。
在一些实施例中，预定义标识为预先设定的寻呼高优先级标识。具体地，可通过对协议进行设置以实现为RAN寻呼信息配置寻呼高优先级标识。
寻呼优先级(Paging Priority)是已有的3GPP38.473协议和3GPP38.423协议中的字段。其中，3GPP38.473协议为基站内集中单元向分布单元发送寻呼消息时的协议，3GPP38.423协议为两个基站之间发送RAN寻呼消息时的协议。通过对3GPP38.473协议和3GPP38.423协议中寻呼优先级的属性取值进行配置，以实现为RAN寻呼信息配置寻呼高优先级 标识。
在一些实施例中，3GPP38.473协议和3GPP38.423协议中关于Paging Priority字段部分的配置如下：
Figure PCTCN2020115394-appb-000001
在一些实施例中，预定义标识为预先设定的用户类型标识。具体地，可通过对协议进行设置以实现为RAN寻呼信息配置寻呼高优先级标识。
更具体地，在已有的3GPP38.473协议和3GPP38.423协议中的增加“User Type”信元，并配置相应属性取值。在一些实施例中，3GPP38.473协议和3GPP38.423协议中关于“User Type”字段部分的配置如下：
Figure PCTCN2020115394-appb-000002
需要说明的是，本申请的技术方案预定义标识的具体形式和内容不作限定。本申请中还可以采用其他方式来为RAN寻呼信息配置预定义标识，此处不再一一举例说明。
通过上述步骤S01和步骤S02可实现为无线接入网寻呼信息配置预定义标识，以供本基站以及相邻基站对被叫端的身份标识进行存储获取对被叫端的身份标识所对应的存储写入时刻进行更新。具体内容可参见后续实施例中描述。

步骤S03、响应于接收到配置有预定义标识的无线接入网寻呼信息，从无线接入网寻呼信息中提取出被叫端的身份标识。
步骤S04、根据被叫端的身份标识和当前时间戳对数据库进行更新。
其中，当前时间戳作为被叫端的身份标识所对应的存储写入时刻。
通过上述步骤S03和步骤S04可实现对用于识别用户是否为VoNR用户的数据库进行更新。
图4为本申请实施例中步骤S04的一种可选实现流程图，如图4所示，该步骤S04包括：
步骤S041、判断数据库中是否存储有被叫端的身份标识。
其中，当判断出数据库中未存储有被叫端的身份标识时，则执行步骤S042；当判断出数据库中存储有被叫端的身份标识时，则执行步骤S043。
步骤S042、将被叫端的身份标识和当前时间戳写入至数据库中。
步骤S043、将数据库中先前存储的与被叫端的身份标识相对应存储写入时刻修改为当前时间戳。
基于上述步骤S041和步骤S043可完成对数据库的更新。
图5为本申请实施例提供的再一种新空口承载语音业务用户识别方法的流程图，该方法的执行主体为基站，该方法不但包括上述步骤S1～步骤S6，还包括步骤S1a和步骤S1b，下面仅对步骤S1a和步骤S1b进行详细描述。其中，步骤S1a位于步骤S2之前执行。
步骤S1a、从无线资源控制连接恢复请求中提取出恢复请求原因值。
步骤S1b、根据恢复请求原因值识别判断无线资源控制连接恢复请求是否由用户端基于无线接入网寻呼所触发的连接恢复流程所发出的请求。
在步骤S1b具体包括：检测恢复请求原因值(Resume Cause)是否为高优先级接入(High Priority Access)、被叫接入(MT-Acces)、移动位置业务优先级接入(MPS-Priority Access)中的一者。
当Resume Cause为High Priority Access、MPS-Priority Access、MPS-Priority Access中的一者时，则判断出RRC Resume Request是由用户端基于RAN寻呼所触发的连接恢复流程所发出的请求；否则，判断出RRC  Resume Request不是由用户端基于RAN寻呼所触发的连接恢复流程所发出的请求。
需要说明的是，本申请的技术方案对步骤S1和步骤S1a的执行顺序不作限定，即步骤S1可以位于步骤S1a之前执行、之后执行或两者同步执行。
在步骤S1b中，当判断出RRC Resume Request是由用户端基于RAN寻呼所触发的连接恢复流程所发出的请求时，则后续执行步骤S2；当判断出RRC Resume Request不是由用户端基于RAN寻呼所触发的连接恢复流程所发出的请求时，则后续执行步骤S6。

步骤S2、基站接收到用户端发送的无线资源控制连接恢复请求后，从该无线资源控制连接恢复请求中提取出用户端的身份标识。
步骤S3、计算接收到无线资源控制连接恢复请求的接收时刻与数据库中用户端的身份标识所对应的存储写入时刻的时间差。
