为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
本公开提供的物联网设备定位和感知方法、网元、系统及电子设备,旨在解决现有技术的如上技术问题。
下面通过对几个示例性实施方式的描述,对本公开实施例的技术方案以及本公开的技术方案产生的技术效果进行说明。需要指出的是,下述实施方式之间可以相互参考、借鉴或结合,对于不同实施方式中相同的术语、相似的特征以及相似的实施步骤等,不再重复描述。
本公开实施例中提供了一种物联网设备定位和感知方法,由应用功能(Application function,AF),如图1所示,该方法包括:
步骤S101、AF向网络开放功能(Network Exposure Function,NEF)发送订阅位置请求,订阅位置请求用于请求订阅IoT设备的位置。
应当理解的是,AF和NEF均为网元;其中,AF类似于一个应用服务器,其与核心网中的控制面网络功能交互,并提供一种或多种业务服务。本公开的AF可以在触发提供与IoT设备的定位相关的业务服务时,发送订阅位置请求。
在一些实施例中,IoT设备的位置可以为地理坐标、室内空间坐标,等。
在一些实施例中,订阅位置请求可以为Nnef_EventExposure_Subscribe请求。
在一些实施例中,订阅位置请求包括IoT设备的标识信息以及参考感知信息,参考感知信息用于指示与IoT设备并置的参考物体的物理信息。
IoT设备的标识信息用于标识IoT设备。例如,IoT设备的标识信息为通用公共订阅标识符(Generic public subscription Identifier,GPSI)、用户永久标识符(Subscription Permanent Identifier,SUPI)等可用于定位的标识符。
在一些实施例中,IoT设备的标识信息为GPSI和SUPI中的至少一种。
本公开实施例的IoT设备可以为智能家居的硬件设备,可以包括移动终端、家用电器以及传感器设备等。例如,IoT设备可以是智能手机、智能音箱、智能冰箱、智能电视、智能灯、智能插座、空气净化器、加湿器、智能油烟机、智能台灯、智能门锁、智能插线板、智能电磁炉、智能摄像头等。IoT设备还可以是烟雾传感器、人体感应器、温度传感器、湿度传感器、门窗感应器、空气质量传感器等。
本公开实施例中IoT设备与参考物体的并置关系,可以是IoT设备位于参考物体的表面,也可以是IoT设备全部位于参考物体的内部,还可以是IoT设备的一部分位于参考物体的内部。
本公开通过在AF中预先存储参考感知信息,相当于建立了IoT设备与参考物体间的对应关系,也即提供IoT设备的位置不会被视为不合理地提供了参考物体的位置。
在一些实施例中,当IoT设备每次更新并置的参考物体后,接入核心网时,都需要向AF上报更新许可信息以及更新后的参考感知信息,可以理解的是,更新后的参考感知信息于指示与IoT设备并置的更新后的参考物体的物理信息。
更新许可信息用于指示已获得更新后的参考物体的所有者的知情和同意。例如,当IoT设备为车载定位器时,该智能行车记录仪首次安装于一辆汽车时,IoT设备需要向AF上报的更新许可信息用于指示以获得该 辆汽车的所有者的知情和同意,参考感知信息可以用于指示该辆汽车的物理信息,例如形状、尺寸等。若后续该智能行车记录仪重新安装于另一辆汽车时,IoT设备需要向AF上报新的更新许可信息,新的更新许可信息用于指示以获得该另一辆汽车的所有者的知情和同意。
通过在订阅位置请求中包括参考感知信息,为后续获得实际感知信息(用于指示与IoT设备并置的实际物体的物理信息),并通过比对实际感知信息与参考感知信息是否一致,来判断参考物体和实际物体是否为同一物体,进而判断是否可以向AF提供IoT设备的位置。本公开实施例可有效避免现有技术中由于在请求订阅IoT设备时仅提供IoT设备的标识信息,导致的无法有效判断在提供IoT设备的位置时是否不合理地提供了与IoT设备并置的实际物体的位置的缺陷。
应当理解的是,本公开实施例中的“一致”,可以指完全一致,也可以是在相似度超过预设阈值的情况下,即视为一致,本公开实施例对于阈值的具体大小不作具体的限定。
在一些实施例中,本公开实施例的物理信息可以是外形或尺寸中的至少一种。
在一些实施例中,确定感知信息的方法的理论依据为:
在短距离无线通信过程中,发射器发射的无线信号通常不会沿直线路径达到接收器;接收器接收到的无线信号是经由环境中各个物体反射、衍射和散射形成的。以室内场景为例,其中,接收器接收到的无线信号是经由室内的家居、人体和其他障碍物的反射、衍射和散射形成的多路信号的叠加,这种现象称为多径效应。具体地说,在短距离无线通信过程中,物理空间中的物体影响了无线信号的传输,环境中的物体(如,家具、墙壁)都可以对无线信号进行“调制”,使得无线信号成为周期性或时变性的信号,对这种周期性或时变性的信号进行分析,可以得到环境中物体的感知信息。
本公开实施例的物联网设备定位和感知方法,不仅在向网络开放功能NEF发送的订阅位置请求中包括IoT设备的标识信息,还进一步包括参考 感知信息,参考感知信息用于指示与IoT设备并置的参考物体的物理信息,相当于建立了IoT设备和参考物体间的对应关系,后续在获得IoT设备的位置时,通过比对实际感知信息与参考感知信息是否一致,来判断参考物体和实际物体是否为同一物体,进而判断是否可以向AF提供IoT设备的位置。本公开实施例可有效避免现有技术中由于在请求订阅IoT设备时仅提供IoT设备的标识信息,导致的无法有效判断在提供IoT设备的位置时,是否不合理地提供了与IoT设备并置的实际物体的位置的缺陷,保证IoT设备的定位信息不被滥用(应当理解的是,当实际感知信息与参考感知信息不一致时,可视为IoT设备的定位信息会被滥用)奠定了基础。
在上述各实施例的基础上,作为一种可选实施例,由应用功能AF执行的物联网设备定位和感知方法还包括:
步骤S201、获得NEF发送的位置通知或者暴露订阅响应。
在一些实施例中,当确定参考感知信息与实际感知信息一致时,说明实际物体就是参考物体,即与IoT设备并置的物体并没有发生改变,因此向AF提供IoT设备的位置,属于合理地提供与IoT设备并置的实际物体的位置,即AF可以获得位置通知。位置通知可以包括IoT设备的位置。
相应地,当确定参考感知信息与实际感知信息不一致时,说明感知到实际物体不是参考物体,与IoT设备并置的物体发生了改变,因此向AF提供IoT设备的位置将属于不合理地提供并置的实际物体的位置,AF可以获得暴露订阅响应。暴露订阅响应包括订阅失败消息,订阅失败消息用于指示订阅IoT设备的位置失败。
在一些实施例中,位置通知可以为Nnef EventExposure Notify消息。
在一些实施例中,暴露订阅响应为Nnef EventExposure Subscribe消息。
在一些实施例中,AF在获得暴露订阅响应后,由于没有获得IoT设备的位置,因此会停止与IoT设备定位相关的业务服务。
在一些实施例中,AF在获得位置通知后,由于获得了IoT设备的位置,因此会开始与IoT设备定位相关的业务服务。
本领域内技术人员可以理解,步骤S201既可以单独被执行,也可以结合步骤S101一起被执行,还可以结合本公开的其他任何一些实施例的步骤一起被执行。
订阅失败消息包括以下至少一种:

标识信息在指示订阅IoT设备的位置失败时,可以记录“拒绝提供IoT设备的位置”的信息,或者记录“提供IoT设备的位置出现故障”的信息,本公开不作具体限定。
订阅IoT设备的位置失败的原因,可以是IoT设备的位置存在被不合理使用的风险、IoT设备并置的物体存在异常变化,等,本公开不作具体限定。

步骤S302、授权AF使用位置业务(Location Service,LCS)服务;
步骤S303、向网关移动定位中心(Gateway Mobile Location Center,GMLC)发送提供定位请求。应当理解的是,GMLC是一种网元。
应当理解的是,若NEF拒绝授权AF使用LCS服务,则NEF不会向GMLC发送提供定位请求,进而导致物联网设备定位和感知流程的终止。
本公开实施例的提供定位请求用于请求获得IoT设备的位置,提供定位请求包括IoT设备的标识信息以及参考感知信息。通过将IoT设备的标识信息和参考感知信息发送至GMLC,以使得GMLC进一步获得实际感知信息,并将实际感知信息与参考感知信息进行比对,并根据比对结果确定是否向AF提供IoT设备的位置,为保证IoT设备的定位信息不被滥用奠定了基础。

在一些实施例中,定位感知信息响应可以为Namf_Location_ProvidePositioningSensingInfo Response消息。
本公开实施例的GMLC获得定位感知信息响应,将定位感知信息响应中包括的实际感知信息与预先获取的参考感知信息进行比对,具体地,可以计算实际感知信息和参考感知信息间的相似度,若确定相似度大于预设阈值,则确定比对结果为一致,若确定相似度不大于预设阈值,则确定比对结果为不一致;还可以直接比对实际感知信息和参考感知信息是否完全一致,若完全一致,则确定比对结果为一致,若确定不完全一致,则确定比对结果为不一致。
在确定比对结果后,既可以生成参考感知信息,参考感知信息的信息内容与比对结果相关,当比对结果为一致,提供定位响应包括IoT设备的位置;当比对结果为不一致,提供定位响应包括订阅失败消息,订阅失败消息用于指示订阅IoT设备的位置失败。
