Description

一种小区测量方法及相关装置
本申请要求于2022年6月13日提交中国专利局、申请号为202210661942.9、申请名称为“一种小区测量方法及相关装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种小区测量方法及相关装置。
背景技术
一般的，处于空闲态或非激活态的终端设备在进行小区选择或小区重选时，需要通过小区测量，选择一个小区驻留。
目前，在终端设备处于空闲态或非激活态定位的场景下，通常采用上述小区选择或上述小区重选过程中的小区测量方法，来寻找合适的小区用于定位请求，以实现上行定位。
但是，上述小区测量方法测得的小区用于上行定位，定位精度较低。
因此，终端设备在空闲态或非激活态定位场景下的小区测量方法还有待改进。
发明内容
本申请实施例提供了一种小区测量方法及相关装置，对终端设备在空闲态或非激活态定位场景下的小区测量进行改进，使测得的小区用于上行定位的定位精度提高。
第一方面，本申请实施例提供了一种小区测量方法，该方法包括：
获取小区信息；
对所述小区信息指示的至少一个小区进行测量，得到测量结果；
基于所述测量结果，确定至少一个目标小区；
向第一网络设备发送定位请求，所述定位请求包括所述至少一个目标小区的信息。
本申请实施例中，提供了一种小区测量方法，终端设备获取小区信息，该小区信息包括但不限于小区标识、小区所在频点、小区的同步信号块SSB发送信息等，该小区标识具体可以是物理小区标识PCI，PCI是小区中基站发送参考信号中携带的小区标识，也可以是其他的小区标识，比如新空口小区全局标识符NCGI等。终端设备对小区信息指示的至少一个小区进行测量，得到测量结果，可理解，终端设备可以是对小区信息指示的部分小区进行测量，也可以是对小区信息指示的全部小区进行测量，得到测量结果，测量结果包括但不限于功率测量值RSRP、功率质量RSRQ、信号与干扰比值RSSI等。终端设备基于测量结果，确定至少一个目标小区，可理解，终端设备确定的目标小区可以是两个或两个以上，多个目标小区用于定位，有助于提高定位精度。终端设备向第一网络设备发送定位请求，该定位请求包括至少一个目标小区的信息，可理解，该定位请求可以是请求上行定位，也可以是请求低功耗高精度定位LPHAP。目前的空闲态或非激活态下的小区测量，只适用于小区选择或小区重选过程，并不适用于定位过程中的小区测量，也没有给出终端设备在定位场景下应该如何进行小区测量的技术内容，换言之，如果按照目前的空闲态或非激活态下的小区测量方法(即上述小区选择、小区重选过程中的小区测量方法)，测量得到的小区不适用于做上行定位，根据测量得到的小区进行定位请求，将大大影响定位精度。相比之下，本申请实施例给出了终端 设备在空闲态或非激活态定位场景下应该如何进行小区测量的技术内容，通过本申请实施例中的小区测量方法，可以得到符合定位要求的目标小区，根据测量得到的目标小区进行定位请求，可以提高定位精度。

下文示出的各个实施例可以适用于图1所示的通信系统，也可以适用于图2所示的通信系统，对此，下文不再赘述。
在详细介绍本申请的方法之前，首先对本申请涉及的一些概念作简单介绍。
1、无线资源控制(radio resource control，RRC)状态以及转换过程
请参阅图3，图3为本申请实施例提供的一种终端设备状态切换示意图。
如图3所示，为无线资源控制(radio resource control，RRC)状态以及状态之间的转换过程。新空口(new radio，NR)引入了一种新的RRC状态，即RRC_INACTIVE(无线资源控制-非激活态)，与RRC_CONNECTED(无线资源控制-连接态)和RRC_IDLE(无线资源控制-空闲态)的转换关系如图3所示。
RRC_INACTIVE(无线资源控制-非激活态)只能从RRC_CONNECTED(无线资源控制-连接态)通过RRC release(释放)消息转变，在UE从RRC_CONNECTED状态释放到RRC_INACTIVE时，基站会分配该UE一个标识I-RNTI(非激活态无线网络临时标识)，并且以此标识存储UE的上下文，此基站也叫做UE的上一个服务gNB(last serving gNB)，有时也被记为锚点gNB(anchor gNB)。
当UE请求恢复之前挂起的RRC连接或者进行无线通知区(radio notification area，RNA)更新时，UE发送RRCResumeRequest消息给当前服务基站，RRCResumeRequest消息结构中包括恢复原因值，该恢复原因值用于指示该RRCResumeRequest消息请求恢复的恢复原因，该RRCResumeRequest消息结构中还包括I_RNTI标识，当前服务基站根据I_RNTI标识去last serving gNB取回UE的上下文。
具体流程可参阅图4，图4为本申请实施例提供的一种终端设备的RRC连接恢复流程示意图。下面对图4的各个步骤进行说明：
S401：UE发送RRC连接恢复请求RRCResumeRequst给gNB，该RRCResumeRequst包含了由last serving gNB为该UE分配的I-RNTI。
S402：gNB接收RRCResumeRequst，并根据I-RNTI中包含的gNB identity时，可以找到last serving gNB并请求其提供UE的上下文。
具体的，gNB向对应的last serving gNB发送上下文获取请求Retrieve UE context request消息。
S403：last serving gNB向gNB提供UE的上下文。
具体的，last serving gNB向gNB发送上下文获取响应Retrieve UE context response消息，该上下文获取响应消息包括UE的上下文。
S404/S405：gNB和UE完成RRC连接的恢复，在获得授权grant的情况下，可以发送用户数据。
S406：如果要求last serving gNB中缓存的下行(downlink，DL)用户数据无损，gNB需要提供转发地址。
S407/S408：gNB进行路径转换。
S409：gNB触发last serving gNB处UE的资源释放。
需要指出的是，在无法取回UE上下文时，gNB可以发送RRCSetup消息给UE，重新建 立RRC连接；或者gNB可以直接发送RRCReject消息给UE，用于拒绝UE的建立请求。
2、小区选择
终端设备在第一次接入网络时，例如终端设备在开机、退出无线资源控制(radio resource control，RRC)连接态(connected state)、进入网络覆盖区域、发生无线链路失败(radio link failure，RLF)的情况下，需要选择一个小区驻留或者RRC重建，这一过程称为小区选择(cell selection)。
示例性地，在小区选择过程中，终端设备可以在多个频率上进行小区搜索。例如，终端设备可以在每个频率上搜索信号强度最强的小区。若搜索到满足小区选择准则的小区，则选择该小区进行驻留。示例性地，上述多个频率可以为终端设备配置的移动网络中小区所在的频率点。例如，上述多个频率可以配置在SIM(subscriber identity module)卡中。
示例性地，上述小区选择准则包括S准则。上述S准则包括：S1>0且S2>0。
示例性地，上述S1可以记为Srxlev，表示小区的小区选择接收电平值。上述S2可以记为Squal，表示小区的小区选择质量值。上述S1和S2满足如下公式：
S1＝Q1-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp
S2＝Q2-(Qqualmin+Qqualminoffset)-Qoffsettemp
其中，Q1为小区的广播消息(例如SSB或SI)的参考信号接收功率(reference signal receiving power，RSRP)，Qrxlevmin表示小区驻留所需的最小RSRP，Qrxlevminoffset表示Qrxlevmin的偏移量，Pcompensation表示功率补偿值，Qoffsettemp表示临时的偏移量。Q2为小区的参考信号接收质量(reference signal receiving quality，RSRQ)，Qqualmin表示小区驻留所需的最小RSRQ，Qqualminoffset表示Qqualmin的偏移量。
示例性地，上述Q1和Q2可以由终端设备对接收到的小区的广播消息(例如SSB、SI)的信号强度进行测量得到。上述参数Qrxlevmin，Qrxlevminoffset，Qqualmin，Qqualminoffset，Pcompensation，Qoffsettemp可以包含在小区的系统信息中或者可以由小区系统信息中的参数推导得出。为了便于描述，本申请实施例中将Qrxlevmin，Qrxlevminoffset，Qqualmin，Qqualminoffset，Pcompensation，Qoffsettemp称为小区选择参数。
示例性地，上述小区选择准则还包括网络归属准则。上述网络归属准则包括：小区所属的网络是终端设备的所选网络(selected network)、注册网络(registered network)或者等效网络(equivalent network)中的任一项。
示例性地，上述小区选择准则还包括小区可用准则。上述小区可用准则包括：小区没有被禁止(barred)或者被预留(reserved)，小区不在漫游禁止跟踪区(forbidden tracking areas for roaming)列表所包含的跟踪区之中。
需要说明的是，上述小区选择准则仅为示例，随着标准技术的演进，小区选择准则可能会发生变化，在该情况下，同样适用于本申请实施例提供的方法。因此，不应将上文所示的小区选择准则理解为对本申请实施的限定。
3、小区重选
处于RRC空闲态(idle state)和RRC非激活态(inactive state)的终端设备可以重新选择其他小区进行驻留，这一过程称为小区重选(cell re-selection)。在小区重选过程中，终端设备首先对服务小区的邻区进行测量，若测量到满足小区重选准则的邻区，则重选到该邻区。
示例性地，小区重选可以包括同频小区重选(intra-frequency cell reselection)和异频小区重选(inter-frequency cell reselection)。同频小区重选是指终端设备重选到与服务小区(serving cell)频率相同的邻区。异频小区重选是指终端设备重选到与服务小区频率不同的邻区。上述 服务小区是指终端设备当前驻留的小区。根据服务小区所在频率和邻区所在频率的优先级，异频小区重选又分为同优先级异频小区重选、低优先级异频小区重选、高优先级异频小区重选。同优先级异频小区重选表示重选到频率优先级等于服务小区的异频邻区，低优先级异频小区重选表示重选到频率优先级低于服务小区的异频邻区，高优先级异频小区重选表示重选到频率优先级高于服务小区的异频邻区。示例性地，上述频率的优先级由网络设备配置。
(1)同频小区重选
示例性地，在终端设备的服务小区的信号强度满足S1≤S1intra或者S2≤S2intra时，终端设备进行同频邻区测量。其中，S1和S2的计算公式可以参见前述小区选择中的相关描述，上述S1intra和S2intra分别为S1和S2的门限值，终端设备在服务小区的S1小于门限值S1intra或者服务小区的S2小于或等于门限值S2intra时，进行同频邻区测量，以便重选到同频邻区。示例性地，S1intra和S2intra可以包含在服务小区的系统信息中。终端设备接收服务小区广播的系统信息，从服务小区的系统信息中得到S1intra和S2intra。
示例性地，终端设备对服务小区的各个同频邻区进行测量。终端设备测量到一个同频邻区，即接收到该同频邻区的广播消息，例如SSB或SI。终端设备首先确定该同频邻区的信号强度是否满足S准则，S准则可以参见前述小区选择的相关描述。若该同频邻区满足上述S准则，则计算该同频邻区的R值。该同频邻区的R值满足如下公式：
R＝Qn-Qoffset-Qoffsettemp,n
其中，Qn为该同频邻区的广播消息(例如SSB或SI)的RSRP，Qoffset为该同频邻区相对服务小区的偏移量，Qoffsettemp,n为该同频邻区的偏移量。Qoffset和Qoffsettemp,n包含在服务小区的系统信息中。
示例性地，终端设备测量到满足上述S准则的至少一个同频邻区，并计算上述至少一个同频邻区的R值。若在规定时间间隔内，第一同频邻区的R值保持大于服务小区的R值，且第一同频邻区满足网络归属准则和小区可用准则，则终端设备确定重选到第一同频邻区。其中，上述第一同频邻区为上述至少一个同频邻区中R值最大的一个。示例性地，上述规定时间间隔可以是由协议规定的，或者由网络设备配置。
示例性地，上述服务小区的R值满足如下公式：
R＝Qs+Qhyst-Qoffsteeemp,s
其中，Qs为服务小区的广播消息(例如SSB、SI)的RSRP，Qhyst为服务小区的滞后量(hysteresis)，Qoffsettemp,s为服务小区的偏移量。示例性地，Qhyst和Qoffsettemp,s两个参数包含在服务小区的系统信息中，Qs可以通过对服务小区广播的SSB的信号强度进行测量得到。为了便于描述，本申请实施例中可以将上述Qoffset，Qoffsettemp,n，Qhyst，Qoffsettemp,s称为小区重选参数。
示例性地，上述小区的R值可以表示小区的小区重选优先级。
(2)同优先级异频小区重选
示例性地，在服务小区的信号强度满足S1≤S1non-intra或者S2≤S2non-intra时，终端设备进行同优先级异频邻区测量。其中，S1和S2可以参见前述小区选择中的相关描述，上述S1non-intra和S2non-intra分别为S1和S2的门限值，终端设备在服务小区的S1小于门限值S1non-intra或者服务小区的S2小于或等于门限值S2non-intra时，进行同优先级异频邻区测量，以便重选到同优先级异频邻区。示例性地，S1non-intra和S2non-intra包含在服务小区的系统信息中。终端设备接收服务小区广播的系统信息，从该系统信息中得到S1non-intra和S2non-intra。
示例性地，终端设备对服务小区的各个同优先级异频邻区进行测量。若测量到的同优先级异频邻区满足S准则，则计算该同优先级异频邻区的R值。上述同优先级异频邻区的R值 的计算参见前述同频小区重选中同频邻区的R值的相关描述。
示例性地，终端设备测量到满足上述S准则的至少一个同优先级异频邻区，并计算上述至少一个同优先级异频邻区的R值。若在规定时间间隔内，第一同优先级异频邻区的R值保持大于服务小区的R值，且第一同优先级异频邻区满足网络归属准则和小区可用准则，则终端设备确定重选到第一同优先级异频邻区。其中，第一同优先级异频邻区为上述至少一个同优先级异频邻区中R值最大的一个。上述服务小区的R值的计算参见前述同频小区重选中服务小区的R值的相关描述。
(3)低优先级异频邻区重选
示例性地，在服务小区的信号强度满足S1≤S1non-intra或者S2≤S2non-intra时，终端设备进行低优先级异频邻区测量。其中，S1和S2可以参见前述小区选择中的相关描述，上述S1non-intra和S2non-intra分别为S1和S2的门限值，终端设备在服务小区的S1小于门限值S1non-intra或者服务小区的S2小于或等于门限值S2non-intra时，进行低优先级异频邻区测量，以便重选到低优先级异频邻区。示例性地，S1non-intra和S2non-intra包含在服务小区的系统信息中。终端设备接收服务小区广播的系统信息，从该系统信息中得到S1non-intra和S2non-intra。
示例性地，终端设备对第一低优先级异频邻区进行测量，上述第一低优先级异频邻区为服务小区的至少一个低优先级异频邻区中的任一个。在上述第一低优先级异频邻区满足S准则、网络归属准则、小区可用准则的情况下，若第一低优先级异频邻区满足低优先级异频邻区重选条件中的一项或多项，则终端设备确定重选到第一低优先级异频邻区。上述低优先级异频邻区重选条件包括如下条件：
条件一：服务小区的S1<Ths,low,p且第一低优先级异频邻区在规定时间间隔内保持S1>Thx,low,p；
条件二：服务小区的S2<Ths,low,q且第一低优先级异频邻区在规定时间间隔内保持S2>Thx,low,q。
其中，Ths,low,p，Thx,low,p，Ths,low,q，Thx,low,q表示的是门限值，这些参数包含在服务小区的系统信息中。在上述第一低优先级异频邻区满足上述低优先级异频邻区重选条件的中的任一项的情况下，终端设备确定重选到第一低优先级异频邻区。
应理解的是，上述低优先级异频邻区重选条件仅为示例，本申请实施例的低优先级异频邻区重选条件不限于上述两种示例，还可以包括随着技术的发展出现的新的其他低优先级异频邻区重选条件。因此，不应将上文所示的低优先级异频邻区重选条件理解为对本申请实施的限定。
(4)高优先级异频小区重选
终端设备对服务小区的高优先级异频邻区进行测量。示例性地，终端设备可以周期性地对高优先级异频邻区进行测量，以便重选到高优先级异频邻区。
示例性地，终端设备对第一高优先级异频邻区进行测量，第一高优先级异频邻区为服务小区的至少一个高优先级异频邻区中的任一个。在上述第一高优先级异频邻区满足S准则、网络归属准则、小区可用准则的情况下，若第一高优先级异频邻区满足高优先级异频邻区重选条件，则终端设备确定重选到第一高优先级异频邻区。上述高优先级异频邻区重选条件包括如下条件：
条件一：第一高优先级异频邻区在规定时间间隔内保持S1>Thx,high,p；
