请参见图1，为本公开适用的一种可能的通信系统10的结构图。
如图1所示，通信系统10包括终端设备101、网络侧设备102以及位置管理功能设备103，下面分别进行说明：
1、终端设备(terminal device，TD)101：简称为终端，是一种具有无线收发功能的设备，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的终端，移动台(mobile station，MS)，终端(terminal)，用户设备(user equipment，UE)，软终端等等。终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。例如，手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(selfdriving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。

可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的定位方法和装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种定位方法的流程图。
如图2所示，该方法应用于网络侧设备，可以包括但不限于如下步骤：
S1：接收位置管理功能LMF设备发送的激活或者去激活上行定位参考信号的指令。
在上行定位技术中，网络侧设备为终端设备配置的上行定位参考信号，在上行定位参考信号为非周期性或者半持续的信号的情况下，为了对终端设备进行定位，还需要激活或者去激活上行定位参考信号。
具体的，在终端设备处于RRC连接态的情况下，网络侧设备可以通过发送媒体接入控制MAC(medium access control，MAC)消息或者下行控制信息DCI(downlink control information，DCI)消息，以使终端设备激活或者去激活上行定位参考信号。其中，在上行定位参考信号为非周期性的信号的情况下，网络侧设备可以通过发送DCI消息，使终端设备激活或者去激活上行定位参考信号；在上行定位参考信号为半持续的信号的情况下，网络侧设备可以通过发送MAC消息，使终端设备激活或者去激活上行定位参考信号。
S2：根据激活或者去激活上行定位参考信号的指令，向处于无线资源控制RRC非连接态的终端设备发送激活命令或者去激活命令。
其中，RRC非连接态具体包括RRC空闲态(RRC idle)/RRC非激活态(RRC inactive)。
本公开实施例中，网络侧设备接收LMF设备发送的激活或者去激活上行定位参考信号的指令，根据激活或者去激活上行定位参考信号的指令，向处于无线资源控制RRC非连接态的终端设备发送激活命令或者去激活命令。
具体的，在终端设备处于RRC非连接态的情况下，本公开实施例中网络侧设备能够将激活命令或者去激活命令发送至终端设备，从而终端设备可以激活或者去激活上行定位参考信号，以实现对终端设备进行定位。
通过实施本公开实施例，网络侧设备接收到LMF设备发送的激活或者去激活上行定位参考信号的指令之后，根据激活或者去激活上行定位参考信号的指令，向处于RRC非连接态的终端设备发送激活命令或者去激活命令，从而处于RRC非连接态的终端设备能够接收网络侧设备发送的激活命令或者去激活命令，以激活或者去激活上行定位参考信号，实现对终端设备进行定位。
请参见图3，图3是本公开实施例提供的另一种定位方法的流程图。
如图3所示，该方法应用于网络侧设备，可以包括但不限于如下步骤：
S1A：接收位置管理功能LMF设备发送的激活或者去激活上行定位参考信号的指令。
其中，S1A与上述实施例中S1存在相同或相近的技术效果，对S1A的具体实施方式的描述，可以参见上述实施例中S1的具体实施方式的描述，此处不再赘述。
S2A：根据激活或者去激活上行定位参考信号的指令，触发终端设备进入RRC连接态后，向终端设备发送激活命令或者去激活命令。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发送上行定位参考信号激活或去激活命令。
基于此，本公开实施例中，在终端设备处于RRC非连接态的情况下，网络侧设备触发终端设备进入RRC连接态，向终端设备发送激活命令或者去激活命令，此时，终端设备能够接收到激活命令或者去激活命令，从而实现激活或者去激活上行定位参考信号，以对终端设备进行定位。
可以理解的是，本公开实施例中网络侧设备触发终端设备进入RRC连接态后，网络侧设备可以通过发送MAC消息或者DCI消息，以使终端设备激活或者去激活上行定位参考信号。其中，在上行定位 参考信号为非周期性的信号的情况下，网络侧设备可以通过发送DCI消息，使终端设备激活或者去激活上行定位参考信号；在上行定位参考信号为半持续的信号的情况下，网络侧设备可以通过发送MAC消息，使终端设备激活或者去激活上行定位参考信号。
示例性实施例中，本公开实施例中向处于无线资源控制RRC非连接态的终端设备发送激活命令或者去激活命令，还包括：在终端设备不存在正在进行的上行SDT的情况下，网络侧设备触发终端设备进入RRC连接态后，向终端设备发送激活命令或者去激活命令。
其中，在终端设备不存在正在进行的上行SDT的情况下，网络侧设备不能直接向终端设备发送激活或去激活命令，因此网络侧设备需触发终端设备进入RRC连接态后，向终端设备发送激活命令或者去激活命令，具体的发送激活命令或者去激活命令方式可以参见上述网络侧设备触发终端设备进入RRC连接态后，向终端设备发送激活命令或者去激活命令的方式的相关论述，此处不再赘述。
在一些实施例中，本公开实施例中在网络侧设备触发终端设备进入RRC连接态后，向处于无线资源控制RRC非连接态的终端设备发送激活命令或者去激活命令之后，控制终端设备处于RRC非连接态。
可以理解的是，终端设备处于RRC非连接态，可以减少终端设备的功耗，本公开实施例中在网络侧设备触发终端设备进入RRC连接态向终端设备发送激活命令或者去激活命令之后，控制终端设备处于RRC非连接态，能够减少终端设备的功耗，进一步节省能源。
请参见图4，图4是本公开实施例提供的又一种定位方法的流程图。
如图4所示，该方法应用于网络侧设备，可以包括但不限于如下步骤：
S1B：接收位置管理功能LMF设备发送的激活或者去激活上行定位参考信号的指令。
其中，S1B与上述实施例中S1存在相同或相近的技术效果，对S1B的具体实施方式的描述，可以参见上述实施例中S1的具体实施方式的描述，此处不再赘述。
S2B：根据激活或者去激活上行定位参考信号的指令，在终端设备存在正在进行的上行小数据发送SDT的情况下，向终端设备发送激活命令或者去激活命令。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发送上行定位参考信号激活或去激活命令。但是，在终端设备存在正在进行的上行SDT(small data transmission，SDT)的情况下，终端设备能够发生上行数据，此时，网络设备也能够直接给终端设备发送下行的数据，例如：终端设备能够接受到网络侧设备向终端设备发送的MAC消息或者DCI消息。
基于此，在上行定位参考信号为非周期性或者半持续的信号的情况下，网络侧设备可以直接通过DCI或MAC消息向RRC非连接态终端设备发送激活或去激活命令，使终端设备激活或者去激活上行定位参考信号。
本公开实施例中，在终端设备存在正在进行的上行SDT的情况下，向终端设备发送激活命令或者去激活命令，如：MAC消息或者DCI消息，从而终端设备能够激活或者去激活上行定位参考信号，以实现对终端设备进行定位，并且，在终端设备存在正在进行的上行SDT的情况下，直接向处于RRC非连接态的终端设备发送激活命令或者去激活命令，不需要网络侧设备向终端设备发送进入RRC连接态的相关的指令之后，在终端设备处于RRC连接态之后，再发送激活命令或者去激活命令，能够进一步降低时延，实现快速激活或者去激活上行定位参考信号。
请参见图5，图5是本公开实施例提供的又一种定位方法的流程图。
如图5所示，该方法应用于网络侧设备，可以包括但不限于如下步骤：
S1C：接收位置管理功能LMF设备发送的激活或者去激活上行定位参考信号的指令。
其中，S1C与上述实施例中S1存在相同或相近的技术效果，对S1C的具体实施方式的描述，可以参见上述实施例中S1的具体实施方式的描述，此处不再赘述。
S2C：根据激活或者去激活上行定位参考信号的指令，向终端设备发送寻呼消息，在终端设备随机接入的过程中，向终端设备发送激活命令或者去激活命令。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发送上行定位参考信号激活或去激活命令。
基于此，本公开实施例中，向终端设备发送寻呼消息，在终端设备随机接入的过程中，向终端设备发送激活或者去激活命令，使终端设备激活或者去激活上行定位参考信号，以实现对终端设备进行定位。在此过程中，不需要在终端设备处于RRC连接态之后，再发送激活命令或者去激活命令，能够进一步降低时延，实现快速激活或者去激活上行定位参考信号。
示例性实施例中，本公开实施例中，在终端设备的随机接入过程中，网络侧设备可以通过MSG2或者MSG4(随机接入消息2/随机接入消息4)给终端设备发送激活命令或者去激活命令，或者网络侧设备可以通过MSGB(随机接入消息B)给终端设备发送激活命令或者去激活命令。
其中，在2步随机接入过程，本公开实施例中，网络侧设备通过MSGB(随机接入消息B)给终端设备发送激活命令或者去激活命令；在4步随机接入过程，本公开实施例中，网络侧设备通过MSG2或者MSG4(随机接入消息2/随机接入消息4)给终端设备发送激活命令或者去激活命令。
示例性实施例中，向处于无线资源控制RRC非连接态的终端设备发送激活命令或者去激活命令，还包括：在终端设备不存在正在进行的上行SDT的情况下，向终端设备发送寻呼消息，在终端设备随机接入的过程中，向终端设备发送激活命令或者去激活命令。
其中，在终端设备不存在正在进行的上行SDT的情况下，网络侧设备不能直接向终端设备发送激活或去激活上行定位参考信号的命令，因此向终端设备发送寻呼消息，在终端设备随机接入的过程中，网络侧设备向终端设备发送激活命令或者去激活命令。网络侧设备向终端设备发送激活命令或者去激活命令的具体方式，可以参见上述网络侧设备向终端设备发送寻呼消息，在终端设备随机接入的过程中，向终端设备发送激活命令或者去激活命令的方式的相关论述，此处不再赘述。
在一些实施例中，本公开实施例中在网络侧设备向终端设备发送寻呼消息，在终端设备随机接入的过程中，向终端设备发送激活命令或者去激活命令之后，控制终端设备处于RRC非连接态。
可以理解的是，终端设备处于RRC非连接态，可以减少终端设备的功耗，本公开实施例中在网络侧设备向终端设备发送寻呼消息，在终端设备随机接入的过程中，向终端设备发送激活命令或者去激活命令之后，控制终端设备处于RRC非连接态，能够减少终端设备的功耗，进一步节省能源。
在一些实施例中，在接收LMF设备发送的激活或者去激活上行定位参考信号的指令之前，还包括：接收LMF设备发送的指示消息；根据指示消息，为终端设备配置上行定位参考信号，其中，上行定位参考信号为非周期性或半持续的信号。
本公开实施例中，LMF设备通过新定义的新无线定位协议A(new radio positioning protocol A，NRPPa)消息向网络侧设备发送指示消息，指示消息可以为定位信息请求消息，该指示消息指示或请求网络侧设备为终端设备配置上行定位参考信号，示例性的，指示信息包含在定位信息请求(POSITIONING INFORMATION REQUEST)消息中。
其中，网络侧设备为终端设备配置的上行定位参考信号为非周期性或半持续的信号，从而，在对终端设备进行定位时，使用上行定位参考信号，需要对上行定位参考信号进行激活或去激活，之后，本公开实施例中接收LMF设备发送的激活或者去激活上行定位参考信号的指令。
在一些实施例中，指示消息，包括预设时长；其中，预设时长为网络测设备成功为终端设备配置上行定位参考信号所需的最长时间。
其中，预设时长包含在定位信息请求(POSITIONING INFORMATION REQUEST)消息中。
本公开实施例中，LMF设备发送的指示消息中包括预设时长，以实现对网络侧设备为终端设备配置上行定位参考信号所需的时间进行限定，进而在网络侧设备为终端设备配置上行定位参考信号使用的时间超出该预设时长时，可以执行相应的操作，以实现某些功能。
在一些实施例中，网络侧设备在预设时长内未能成功为终端设备配置上行定位参考信号，向LMF设备发送第一错误指示消息。

如图7所示，该定位方法应用于终端设备，可以包括但不限于如下步骤：
S111：在终端设备处于RRC非连接态的情况下，接收网络侧设备发送的激活命令或者去激活命令。
其中，RRC非连接态具体包括RRC空闲态(RRC idle)/RRC非激活态(RRC inactive)。
在上行定位技术中，网络侧设备为终端设备配置的上行定位参考信号，在上行定位参考信号为非周期性或者半持续的信号的情况下，为了对终端设备进行定位，还需要激活或者去激活上行定位参考信号。
具体的，在终端设备处于RRC连接态的情况下，网络侧设备可以通过发送MAC消息或者DCI消息，以使终端设备激活或者去激活上行定位参考信号。其中，在上行定位参考信号为非周期性的信号的情况下，网络侧设备可以通过发送DCI消息，使终端设备激活或者去激活上行定位参考信号；在上行定位参考信号为半持续的信号的情况下，网络侧设备可以通过发送MAC消息，使终端设备激活或者去激活上行定位参考信号。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发送上行定位参考信号激活或去激活命令。但是，在本公开实施例中，终端设备处于RRC非连接态的情况下，能够接收到激活命令或者去激活命令。
S112：根据激活命令或者去激活命令，激活或者去激活上行定位参考信号。
本公开实施例中在终端设备处于RRC非连接态的情况下，接收网络侧设备发送的激活命令或者去激活命令，从而终端设备可以根据根据激活命令或者去激活命令，激活或者去激活上行定位参考信号，以实现对终端设备进行定位。

请参见图8，图8是本公开实施例提供的又一种定位方法的流程图。

S111A：在终端设备处于RRC非连接态的情况下，接收网络侧设备发送的触发终端设备进入RRC连接态的指令，终端设备进入RRC连接态，接收网络侧设备发送的激活命令或者去激活命令。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发 送上行定位参考信号激活或去激活命令。基于此，本公开实施例中，在终端设备处于RRC非连接态的情况下，终端设备接收网络侧设备发送的触发终端设备进入RRC连接态的指令，终端设备进入RRC连接态，接收网络侧设备发送的激活命令或者去激活命令，此时，终端设备能够接收到激活命令或者去激活命令，从而实现激活或者去激活上行定位参考信号，以对终端设备进行定位。
可以理解的是，本公开实施例中终端设备接收网络侧设备发送的触发终端设备进入RRC连接态的指令之后，进入RRC连接态后，网络侧设备可以通过发送MAC消息或者DCI消息，以使终端设备激活或者去激活上行定位参考信号。其中，在上行定位参考信号为非周期性的信号的情况下，终端设备接收网络侧设备发送的DCI消息，激活或者去激活上行定位参考信号；在上行定位参考信号为半持续的信号的情况下，终端设备接收网络侧设备发送的MAC消息，激活或者去激活上行定位参考信号。

其中，S112A与上述实施例中S112存在相同或相近的技术效果，对S112A的具体实施方式的描述，可以参见上述实施例中S112的具体实施方式的描述，此处不再赘述。
请参见图9，图9是本公开实施例提供的又一种定位方法的流程图。

S111B：在终端设备处于RRC非连接态的情况下，在终端设备存在正在进行的上行小数据发送SDT的情况下，接收网络侧设备发送的激活命令或者去激活命令。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发送上行定位参考信号激活或去激活命令。但是，在终端设备存在正在进行的上行SDT的情况下，终端设备能够发生上行数据，此时，网络设备也能够直接给终端设备发送下行的数据，例如：终端设备能够接收网络侧设备发送的MAC消息或者DCI消息。
基于此，终端设备可以接收网络侧设备发送的DCI消息或者MAC消息，激活或者去激活上行定位参考信号。
本公开实施例中，在终端设备存在正在进行的上行SDT的情况下，接收网络侧设备发送的激活命令或者去激活命令，如：MAC消息或者DCI消息，从而终端设备能够激活或者去激活上行定位参考信号，以实现对终端设备进行定位，并且，在终端设备存在正在进行的上行SDT的情况下，直接在终端设备处于RRC非连接态的情况下，接收网络侧设备发送的激活命令或者去激活命令，不需要在接收到网络侧设备发送的触发终端设备进入RRC连接态的相关的指令之后，切换到RRC连接态，再激活或者去激活上行定位参考信号，能够进一步降低时延，实现快速激活或者去激活上行定位参考信号。
S112B：根据激活命令或者去激活命令，激活或者去激活上行定位参考信号。
其中，S112B与上述实施例中S112存在相同或相近的技术效果，对S112B的具体实施方式的描述，可以参见上述实施例中S112的具体实施方式的描述，此处不再赘述。
请参见图10，图10是本公开实施例提供的又一种定位方法的流程图。
如图10所示，该方法应用于终端设备，可以包括但不限于如下步骤：
S111C：在终端设备处于RRC非连接态的情况下，接收网络侧设备发送的寻呼消息，在随机接入 过程中接收网络侧设备发送的激活命令或者去激活命令。
可以理解的是，终端设备处于RRC非连接态时，一般情况下，网络侧设备不能直接给终端设备发送上行定位参考信号激活或去激活命令。
基于此，本公开实施例中，接收网络侧设备发送的寻呼消息，终端设备在随机接入过程中，接收网络侧设备发送的激活命令或者去激活命令，激活或者去激活上行定位参考信号，以实现对终端设备进行定位，在此过程中，不需要在终端设备处于RRC连接态之后，再发送激活命令或者去激活命令，能够进一步降低时延，实现快速激活或者去激活上行定位参考信号。
示例性实施例中，本公开实施例中，终端设备随机接入的过程中，可以接收网络侧设备通过MSG2或者MSG4(随机接入消息2/随机接入消息4)发送的激活命令或者去激活命令，或者可以接收网络侧设备通过MSGB(随机接入消息B)发送的激活命令或者去激活命令。
其中，在2步随机接入过程，本公开实施例中，终端设备可以接收网络侧设备通过MSGB(随机接入消息B)发送的激活命令或者去激活命令；在4步随机接入过程，本公开实施例中，终端设备可以接收网络侧设备通过MSG2或者MSG4(随机接入消息2/随机接入消息4)发送的激活命令或者去激活命令。

其中，在终端设备不存在正在进行的上行SDT的情况下，终端设备接收网络侧设备发送的寻呼消息，在随机接入过程中接收网络侧设备发送的激活命令或者去激活命令的具体方式，可以参见上述终端设备接收网络侧设备发送的寻呼消息，在随机接入过程中接收网络侧设备发送的激活命令或者去激活命令的方式的相关论述，此处不再赘述。
S112C：根据激活命令或者去激活命令，激活或者去激活上行定位参考信号。
其中，S112C与上述实施例中S112存在相同或相近的技术效果，对S112C的具体实施方式的描述，可以参见上述实施例中S112的具体实施方式的描述，此处不再赘述。
在一些实施例中，本公开实施例中提供的定位方法，还包括：接收LMF设备发送的定位能力请求消息；其中，定位能力请求消息用于至少请求获取终端设备的类型和/或移动状态。
可以理解的是，终端设备的上行定位参考信号是特定的，为终端设备所处的服务小区给终端设备配置的上行定位参考信号，例如网络侧设备可以使用RRC release消息给终端设备配置用于终端设备处于RRC非连接态时的上行定位参考信号，但是由于终端设备的移动，例如，终端设备移动超出服务小区的范围，此时，终端设备配置的上行定位参考信号会存在失效的问题，此时，网络侧设备不能通过给终端设备配置的上行定位参考信号对终端设备进行定位，即不适合使用上行定位方法对此类移动速度较快的终端设备进行定位。
另外，终端设备的类型也能反映出终端的移动状态，例如某种特定类型的终端设备，例如IIoT(industrial internet of things，工业物联网)终端设备，其移动速度小，移动范围受限，如果网络侧设备给其配置了用于RRC非连接态的上行定位参考信号，通常该上行定位参考信号不会失效，因此，这种类型的终端设备处于RRC非连接态时也适用上行定位方法。
需要说明的是，采用使用RRC release消息为终端设备配置上行定位参考信号的定位方法，还可以 与终端设备的其他条件相关，可以根据需要进行设置，本公开对此不作具体限制。
基于此，本公开实施例中终端设备接收LMF设备发送的定位能力请求信息，至少请求获取终端设备的类型和移动状态，以获取终端设备的类型和/或移动状态。
其中，定位能力请求消息为LPP要求能力(Request Capabilities)消息。
在一些实施例中，终端设备根据定位能力请求消息将终端设备的类型和/或移动状态发送至LMF设备。
本公开实施例中终端设备在接收到LMF设备发送到的定位能力请求消息之后，根据该定位能力请求消息，将终端设备的类型和/或移动状态发送至LMF设备，从而可以对终端设备处于RRC非连接态时是否适用于上行定位方法，在适用于上行定位方法的情况下，采用该方法对终端设备进行定位，以实现提高对终端设备定位的精确度。
本公开实施例中，终端设备向LMF设备发送到终端设备的类型和/或移动状态包含在LPP提供功能(Provide Capabilities)消息中。
