Description
本公开涉及通信领域,尤其涉及最小化路测MDT方法及装置、存储介质。
NPN(Non-Public Network,非公共网络)由R16(Release 16,版本16)引入并于R17(Release 17,版本17)进行了一系列增强,然而一直没有引入相关SON(Self-Organized Network,自组织网络)、MDT(Minimization of Drive-Tests,最小化路测)增强。考虑到由于相关技术方案已经比较稳定并且有很好的商业部署前景,因此在R18中引入针对NPN的SON、MDT增强。
目前协议中仅支持基于网络配置的PLMN(Public Land Mobile Network,公共陆地移动网络)相关信息执行logged(记录)MDT,不支持NPN场景下的logged MDT。

考虑到目前协议中仅支持基于网络配置的PLMN相关信息执行logged MDT,不支持NPN场景下的logged MDT。为了解决上述技术问题,本公开提供了以下MDT方法。
下面先从终端侧介绍一下本公开提供的MDT方法。
本公开实施例提供了一种最小化路测MDT方法,参照图1所示,图1 是根据一实施例示出的一种最小化路测MDT方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤101中,接收网络侧设备发送的非公共网络NPN相关信息;其中,所述NPN相关信息用于配置logged MDT。
在步骤102中,基于所述NPN相关信息,执行所述logged MDT。
在一个可能的实现方式中,终端可以基于NPN相关信息,执行所述logged MDT测量记录和所述logged MDT测量记录上报中的至少一项。
上述实施例中,可以由网络侧设备配置NPN相关信息,终端基于该NPN相关信息,在NPN场景下执行logged MDT。本公开支持NPN场景下的logged MDT,扩展了logged MDT的应用场景,可用性高。
在一些可选实施例中,参照图2所示,图2是根据一实施例示出的一种最小化路测MDT方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤201中,接收网络侧设备通过LoggedMeasurementConfiguration(记录测量配置)消息发送的所述NPN相关信息;其中,所述NPN相关信息用于配置logged MDT。
在步骤202中,基于所述NPN相关信息,执行所述logged MDT。
在一个可能的实现方式中,终端可以基于NPN相关信息,执行所述logged MDT测量记录和所述logged MDT测量记录上报中的至少一项。上述实施例中,可以由网络侧设备配置NPN相关信息,并通过LoggedMeasurementConfiguration消息发送给终端,终端基于该NPN相关信息,在NPN场景下执行logged MDT测量记录。本公开支持NPN场景下的logged MDT,扩展了logged MDT的应用场景,可用性高。
在一些可选实施例中,NPN相关信息包括以下至少一项:MDT NPN List(MDT NPN列表);logging area(记录区域);logging duration(记录持续时长)。
在一个可能的实现方式中,MDT NPN列表包括允许所述终端进行记 录和上报的NPN。
在一个可能的实现方式中,终端在记录区域内执行所述logged MDT测量。
在一个可能的实现方式中,记录持续时长用于指示所述终端执行所述logged MDT测量的持续时长。
上述实施例中,终端可以基于上述NPN相关信息,执行logged MDT测量记录,实现简便,可用性高。
在一个可能的实现方式中,MDT NPN列表可以适用于以下至少一项:基于管理的MDT;基于信令的MDT。
其中,基于管理的MDT是对应一组终端而言的,基于信令的MDT是针对单个终端而言的。
在一个可能的实现方式中,MDT NPN列表可以为以下至少一项:CAG(Closed Access Group,闭合接入组)标识列表;PNI-NPN(Public Network Integrated NPN,公共以及非公共集成网络)标识列表;NID(Network Identifier,网络标识)列表;SNPN(Stand-alone Non-Public Network,独立非公共网络)标识列表。
其中,PNI-NPN标识可以包括以下至少一项:PLMN标识;CAG标识。
其中,SNPN标识包括以下至少一项:PLMN标识;NID。
需要说明的是,网络侧设备在确定终端同意注册NPN中上报位置信息的情况下,可以将MDT NPN列表配置给所述终端。
在一个可能的实现方式中,记录区域可以包括所述MDT NPN列表中的NPN中的小区,如果网络侧设备未配置该记录区域,终端将记录MDT NPN列表中所有NPN中的小区的测量值。
在本公开实施例中,记录区域可以包括以下至少一项:小区列表;TA(Tracking Area,跟踪区)列表;LA(Location Area,位置区)列表;RA(Registration Area,注册区)列表。其中,小区列表可以包括NPN标识和小区标识。
需要说明的是,PLMN的小区列表可以通过global Cell ID(global Cell Identifier,全球小区标识)来指示,全球小区标识可以包括PLMN标识与cell ID(cell Identifier,小区标识)。对应NPN中的小区列表中的小区可以通过NPN标识和小区标识来指示。
一旦网络侧设备配置了记录区域,则终端仅在这些区域内执行测量记录。如果网络侧设备未配置记录区域,则终端只要确定注册NPN属于配置的NPN MDT列表,就执行测量。
具体地,记录区域包括小区列表的情况下,终端只在驻留在这些小区的时候执行测量。
记录区域包括TA列表、LA列表、RA列表中至少一项的情况下,终端只在驻留在属于预配置的TA、LA、RA的小区时执行测量。
如果网络侧设备未配置记录区域,终端只要确定注册NPN属于NPN MDT列表,就执行logged MDT测量。
可选地,终端可以基于SIB1中npn-IdentityList(NPN标识列表)的条目以及对应的小区标识、TAC(Tracking Area Code,跟踪区代码)来判断自身是否处于记录区域内。
在同一小区内存在多个运营商的情况下,npn-IdentityList中包括多个条目,终端可以基于npn-IdentityList中的第一个条目以及对应的小区标识、TAC来判断自身是否在记录区域内。
在同一小区内存在唯一运营商的情况下,npn-IdentityList中包括一个条目,终端可以基于npn-IdentityList中的唯一条目以及对应的小区标识、TAC来判断自身是否在记录区域内。
在一个可能的实现方式中,记录持续时长用于配置在指定时刻激活的定时器;其中,所述定时器的定时时长与所述记录持续时长相等。
在本公开实施例中,指定时刻激活是指终端收到网络侧设备发送的配置的时刻,将网络侧设备配置的值Logging duration(记录持续时长)作为该定时器的定时时长,并激活定时器。
在本公开实施例中,该定时器的运行不受终端状态变化或注册NPN变化的影响。其中,终端状态变化可以指终端在连接态、空闲态、非激活态之间进行状态切换。
需要说明的是,如果终端发生了RAT(Radio Access Type,无线接入类型)的改变,则该定时器可以停止并清除配置及测量记录,也可以继续运行。
其中,RAT的改变是指从LTE(Long Term Evolution,长期演进)系统切换到NR(New Radio,新空口)系统,或者从NR切换到LTE,本公开对此不作限定。具体实现方式在后续实施例中介绍,此处暂不介绍。
在一些可选实施例中,参照图3A所示,图3A是根据一实施例示出的一种最小化路测MDT方法流程图,可以用于终端,该方法可以包括以下步骤:

在一些可选实施例中,参照图5所示,图5是根据一实施例示出的一种最小化路测MDT方法流程图,可以用于终端,该方法可以包括以下步骤:

在另一个可能的实现方式中,可以通过协议约定在SNPN、PNI-NPN场景下是否需要停止定时器。终端基于协议约定的内容,确定是否停止定时器。
例如,协议约定在SNPN场景下需要停止定时器,PNI-NPN场景下无需停止定时器,则终端在确定处于SNPN场景下时,停止该定时器,在确定处于PNI-NPN场景下时确定不停止该定时器。
