Description

定位测量上报方法及装置、存储介质、第三网元

具体实施方式
如前所述，在现有技术中，已经形成了丰富的解决方案，既包括基于无线接入网的定位技术，也包括独立于无线接入网的定位技术。
具体地，业界提出的解决方案大致有如下3类：
(1)基于无线接入网(Radio Access Technology，RAT)的定位技术，又具体包括多种方法，例如增强小区标识定位法(Enhanced Cell ID，E-CID)、下行到达时间观测差定位法(Observed Time Difference of Arrival，OTDOA)、上行到达时间观测差定位法(Uplink Time Difference of Arrival，UTDOA)、E-CID+OTDOA、OTDOA+UTDOA等。
(2)独立于无线接入网的定位技术，又具体包括多种方法，例如辅助全球导航卫星系统定位(network-Assisted GNSS methods，A-GNSS)、基于蓝牙(Bluetooth)的定位、基于WiFi的定位、基于定位传感器的惯性测量单元(IMU,Inertial Measurement Unit)定位、A-GNSS+IMU、A-GNSS+WiFi等。
(3)基于RAT和独立RAT的混合定位技术，又具体包括A-GNSS+OTDOA、A-GNSS+UTDOA等多种方法。
基于无线接入网的定位技术，如果要实现对UE的定位，可以由核心网网元定位服务器参与，所述定位服务器可以是通过测量和其他定位信息来管理UE定位的一个物理或逻辑实体，如位置管理功能(Location Management Function，LMF)或者安全用户面定位(Secure User Plane Location)定位平台(Location Platform)，或者E-SMLC。为完成UE定位，定位服务器可能会向UE提供一些辅助数据。定位服务器可能会计算(UE辅助的)或者确认(UE主导的)最终的定位结果。
进一步地，定位方法根据做最终计算定位结果的位置不同，可以分为UE-assisted，UE-based两种。
UE-assisted定位，由UE向定位服务器(LMF)提供测量结果， 在OTDOA场景下即RSTD测量结果，定位服务器负责计算定位结果。
UE-based定位，UE不仅负责定位相关的测量，还负责定位结果的计算。
NRPPa(The NR Positioning Protocol A)是负责在基站和定位服务器间传输信息的协议，负责收集基站处数据，如每秒请求数(Request Per Second，RPS)的配置信息；传输辅助信息，传输定位的测量信息等等。NR定位协议A(NR Positioning Protocol A，NRPPa)协议对网络协议(Action Message Format，AMF)是透明的，AMF基于路由(Routing)ID透传NRPPa协议数据单元(Protocol Data Unit，PDUs)。
在3GPP#112e次会议中，同意支持在RRC非连接态(RRC_Inactive)下的定位功能。为了支持RRC_Inactive下的定位，对于用户终端-辅助(UE-assisted)定位方法而言，UE需要向核心网网元定位服务器(LMF)提供定位的测量数据。对于基于用户终端(UE-based)定位方法而言，如果有需要，UE需要将定位估计结果上报给网络。
因此，RRC_Inactive下定位需要UE支持在RRC_Inactive下，向网络上报定位测估结果/估计结果给网络。目前NR(New Radio)中还不支持该功能。在正在进行的R17的小数据包的传输(Small data transmission，SDT)课题中，正在研究在RRC_Inactive下支持小数据包的传输。定位中可以使用该课题的解决方案传输定位数据。
另外，后续标准中还可能支持在RRC空闲态(RRC_Idle)下支持定位功能，为了支持RRC_Idle态下的定位，对于用户终端辅助的定位方法而言，UE需要向核心网网元LMF提供定位的测量数据。对于基于用户终端的定位方法，如果有需要，用户需要将定位估计结果上报给网络。
然而在现有技术中，UE如果需要传输数据给网络只有处于连接 态才可以，如果UE在RRC_IDLE或RRC_Inactive态，需要转入连接态来传输数据。
小数据传输课题研究的就是UE保留在Inactive态或者Idle传输上行、下行数据报的传输方法，包括但不限于小数据传输(Small data transmission，SDT)和早期数据传输(Early data transmission，EDT)方法。其中，SDT课题的解决方案分两种，一种是基于随机接入信道(Random Access Channel，RACH)的解决方案，即RACH-based的解决方案，一种是基于免调度的解决方案，即Configured grant-based的解决方案。RACH-based解决方案在2-step/4-step RACH中的信息(Massage，MSG)A/3中将小数据包发送给网络，而不需要转入连接态。在小数据传输中，是否支持小数据传输是网络每数据无线承载(data radio bearer，DRB)配置的。但在具体实施时还会配置一个第一数据阈值，即如果当前需要传输的数据量小于第一数据阈值时，UE使用SDT/EDT传输数据，如果当前需要传输的数据量大于等于第一数据阈值时，UE转到连接态传输。设置该第一数据阈值的目的是保证正常数据传输仍然需要转到连接态来进行，而对于小数据传输可以保留在RRC_Inactive态或者RRC_Idle态进行。
本发明的发明人经过研究发现，小包传输的数据量一般在几十到300byte之间，然而，定位数据，特别是定位测量结果的数据量一般都大于300byte，所以，如果定位的第一数据阈值和上述正常SDT/EDT的第一数据阈值一样的话，对于定位数据而言，可能大部分数据传输都需要转到连接态进行。那进行SDT/EDT传输就没有太大增益。
在本发明实施例中，通过设置第三网元确定传输SDT/EDT的第一数据阈值或者对第一网元的待上报的定位测估结果的数据量进行估计以得到估计值，可以使得第三网元更加了解第一网元的情况，进而在直接或间接发送信息至所述第一网元后，使得第一网元根据收到的信息进行定位测量并上报定位测估结果，有效摆脱现有的正常SDT/EDT的第一数据阈值的限制，提高基于SDT/EDT的定位测量上 报效率。

其中，所述第一网元的请求例如可以是第一网元发出的定位请求信息。
在步骤S22的具体实施中，第三网元可以确定第一网元定位测量的一个或多个用于指示测量精度的精度参数。
进一步地，所述用于指示测量精度的精度参数可以包括以下一项或多项：定位测量的分辨率、测量的参考信号的信号数量。
具体地，所述定位测量的分辨率可以是NR-实时动态码相位差分技术(Real Time Differential，RTD)的分辨率，通过改变NR-RTD的分辨率，可以改变测量到的数据量的大小。
通过挑选出合适的测量的参考信号的信号数量，例如减少或增大测量的参考信号的数量，可以改变测量到的数据量的大小。

以TDOA定位方法为例，第三网元可以配置上报的测量对象可以包括所在位置分散的比较均匀的TRP的测量结果，如在第一网元周边预设范围内，例如可以为选择测试范围内，分布密度过大或过小 的不予采用，而是采用分布密度位于预设密度范围内的TRP，即较为均匀分布的TRP的测量结果。
第三网元可以配置上报的测量对象还可以包括RSRP值大于预设RSRP阈值的参考信号，通过设置预设RSRP阈值，可以避免对信号强度过小的RSRP参考信号的测量结果进行上报。
在本发明实施例中，采用第二种具体实施方式，所述定位指示信息包括测量对象指示信息，确定定位指示信息包括：根据所述第一数据阈值确定第一网元定位测量的一个或多个测量对象；采用所述一个或多个测量对象配置所述测量对象指示信息。可以使得第三网元能够根据已确定的第一数据阈值对第一网元的测量对象进行客制化配置，例如在第一数据阈值较小时减少测量对象，从而有利于第一网元在测估过程中调整测量对象后，得到的测估结果更加符合第一数据阈值。

参照图5，图5是本发明实施例中一种定位测量上报方法的第四种具体实施方式的流程图。所述定位测量上报方法的第四种具体实施方式可以用于第三网元，还可以包括步骤S51至步骤S54：
步骤S51：确定第一数据阈值；
步骤S52：对第一网元的待上报的定位测估结果的数据量进行估计以得到估计值；
步骤S53：比较所述估计值与所述第一数据阈值，并基于比较结果确定是否需要第一网元对待上报的定位测估结果进行分段或合并；
步骤S54：如果需要第一网元对待上报的定位测估结果进行分段，则在所述分段合并指示信息中指示对所述待上报的定位测估结果进行分割的分割信息；
步骤S55：如果需要第一网元对待上报的定位测估结果进行合并， 则在所述分段合并指示信息中指示需要对所述待上报的定位测估结果进行合并的合并信息；
步骤S56：向第一网元发送所述定位指示信息，以使得所述第一网元根据所述定位指示信息进行定位测量并上报。
其中，所述定位指示信息包括分段合并指示信息，所述分段合并指示信息用于指示第一网元是否对待上报的定位测估结果进行分段或合并。
有关步骤S51以及步骤S56的更多内容，可以参照前文以及步骤S21以及步骤S24的具体描述进行执行，此处不再赘述。
在步骤S52的具体实施中，第三网元可以采用适当的常规方式估算第一网元上报的数据量。例如可以根据其配置的定位指示信息进行估算，还可以根据该第一网元的测量数据上报历史数据进行估计。
在步骤S53的具体实施中，第三网元可以比较所述估计值与所述第一数据阈值，如果估计值大于甚至远大于第一数据阈值，则可以确定需要第一网元对待上报的定位测估结果进行分段，如果估计值小于甚至远小于第一数据阈值，则可以确定需要第一网元对待上报的多个定位测估结果进行合并。
在步骤S54的具体实施中，所述分割信息可以包括对所述待上报的定位测估结果分割为多少个PDU；所述分割信息可以包括对所述待上报的定位测估结果进行分割后的每个PDU的上限。
在本发明实施例中，通过设置分割信息包括PDU的数量，或者包括每个PDU的上限，可以实现准确分割。
在步骤S55的具体实施中，所述合并信息可以包括对所述待上报的定位测估结果中的多少个PDU进行合并上报；所述合并信息可以包括对所述待上报的定位测估结果中的多个PDU进行合并的每个PDU的上限。
在本发明实施例中，通过设置分割信息包括PDU的数量，或者包括每个PDU的上限，可以实现准确合并。
在本发明实施例中，采用第四种具体实施方式，所述定位指示信息包括分段合并指示信息，确定定位指示信息包括：对第一网元的待上报的定位测估结果的数据量进行估计以得到估计值；比较所述估计值与所述第一数据阈值，并基于比较结果确定是否需要第一网元对待上报的定位测估结果进行分段或合并。可以使得第三网元能够根据已确定的第一数据阈值对第一网元的数据包大小进行客制化配置，例如在第一数据阈值较小时将较大的数据包分割为较小的数据包，从而有利于第一网元调整数据包大小后，更加符合第一数据阈值。
进一步地，还可以根据对第一网元的待上报的定位测估结果的数据量进行估计以得到的估计值，实现定位测量上报。
参照图6，图6是本发明实施例中一种定位测量上报方法的第五种具体实施方式的流程图。所述定位测量上报方法的第五种具体实施方式可以用于第三网元，还可以包括步骤S61：
步骤S61：发送所述定位上报估计值至第二网元，以使所述第二网元确定所述第一网元的第二数据阈值，并将所述第二数据阈值发送至所述第一网元，以使得所述第一网元根据所述第二数据阈值进行定位测估结果的上报。
在步骤S61的具体实施中，第三网元将定位测量结果数据量的估计值(UE上报的定位测量数据量的推荐值)提供给第二网元。
进一步地，根据为所述第一网元的定位测量进行配置后的配置参数估算出的数据量；或者，根据所述第一网元的历史上报数据估算出的数据量。
具体地，该定位上报估计值可以是第三网元根据其配置估算出的值，也可以是第三网元根据第一网元的测量数据上报历史估计出的值。
需要指出的是，所述定位测量结果数据量的估计值是第三网元对单次测量上报的数据量大小的估计，仅对上报次数为单次进行限制，并不对数据包的数量进行限制，可能是一个数据包的大小也可能是多个数据包的大小。
进一步地，发送所述定位上报估计值至第二网元包括：所述定位上报估计值通过以下一种或多种消息传输：NRPPa消息、LPPa消息。
上述定位上报估计值可以通过NRPPa消息发送至第二网元，第二网元可以根据该信息，结合自身的负载状况等因素，确定SDT/EDT的门限值。第二网元后将该确定的阈值信息通过RRCRelease消息或者系统信息发送给第一网元。
如前所述，具体的NRPPa信息可以包含一种或多种适当的消息。
进一步地，在步骤S61之前，即对第一网元的待上报的定位测估结果的数据量进行估计以得到估计值之前，还可以包括：确定所述第一网元采用的定位方法为UE-assisted的定位方法。
具体地，图6示出的方法更适用于UE-assisted定位方法，即第三网元仅在定位方法是UE-assisted时，才会发送数据估计值信息给第二网元。这是因为在另一种UE-based定位方法中，第一信元只需要上报定位估计结果，数据量有限，不需要修改SDT/EDT的第一数据阈值。
在本发明实施例中，采用第五种具体实施方式，将所述估计值发送至第二网元，以使第二网元基于所述估计值与传输SDT/EDT的第一数据阈值确定实际供所述第一网元传输SDT/EDT的实际第一数据阈值，并将所述实际第一数据阈值发送至所述第一网元，可以使得第二网元能够根据接收到的估计值对第一网元实际传输SDT/EDT的第一数据阈值进行客制化配置，从而有利于第一网元的测估过程和测估结果更加符合第一数据阈值，有效避免由于现有的正常SDT/EDT的第一数据阈值的限制导致通信错漏，提高基于SDT/EDT的定位测量 上报效率。
在本发明实施例中，通过设置第三网元确定传输SDT/EDT的第一数据阈值或者对第一网元的待上报的定位测估结果的数据量进行估计以得到估计值，可以使得第三网元更加了解第一网元的情况，进而在直接或间接发送信息至所述第一网元后，使得第一网元根据收到的信息进行定位测量并上报定位测估结果，有效摆脱现有的正常SDT/EDT的第一数据阈值的限制，提高基于SDT/EDT的定位测量上报效率。
参照图7，图7是本发明实施例中一种定位测量上报装置的结构示意图。所述定位测量上报装置可以包括：
确定模块71，用于确定第一数据阈值或者确定定位上报估计值，所述第一数据阈值用于指示传输信息的数据量的上限，所述定位上报估计值是对第一网元的定位上报数据量的估计值；
