技术领域
本申请涉及定位技术领域，尤其涉及一种定位过程中的通信方法及通信装置。
背景技术
终端设备需要执行定位测量时，可向接入网设备请求定位参考信号(positioning reference signal，PRS)相应的测量配置。接入网设备响应终端设备的请求，向终端设备发送与请求相应的测量配置，以用于终端设备进行定位测量。为了降低定位时延，目前提出接入网设备可预配置定位参考信号的测量信息。针对网络中存在预配置定位参考信号的测量信息的情况，终端设备如何执行定位测量流程，还没有相应的方案。
发明内容
本申请提供一种通信方法及通信装置，用于针对预配置定位参考信号的测量信息的情况，提供终端设备执行定位测量的流程。
第一方面，提供了一种通信方法可由第一通信装置执行，第一通信装置可以是终端设备，或者该第一通信装置为能够支持终端设备实现该方法所需的功能的通信装置，例如芯片系统。应理解，芯片系统可设置在终端设备中。下面以第一通信装置为终端设备为例进行描述。该方法包括：
终端设备确定满足第一条件和/或第二条件，发送请求消息。其中，第一条件为预配置的测量信息可用，且预配置的测量信息中的至少一套测量信息满足终端设备的测量需求。测量信息为定位参考信号的测量信息，包括MG的配置信息和/或PPW的配置信息。预配置的测量信息可用，也可以理解为，预配置了测量信息。第二条件为预配置的测量信息被允许通过媒体接入控制(media access control，MAC)控制单元(control element，CE)信令请求激活。也可以理解为，第二条件为接入网设备允许终端设备通过MAC CE信令请求激活预配置的测量信息。请求消息可用于请求激活预配置的测量信息中的至少一套测量信息，或者，请求消息用于请求定位参考信号的测量信息。也可以理解为，终端设备发送请求消息之前，可判断是否满足第一条件和/或第二条件。当终端设备确定满足第一条件和/或第二条件，发送请求消息。
例如，终端设备确定满足第一条件，请求消息可用于请求激活预配置的测量信息中的至少一套测量信息，或者，请求消息可用于请求预配置的测量信息中的至少一套测量信息。又例如，终端设备确定满足第二条件，请求消息可用于请求激活预配置的测量信息中的至少一套测量信息，或者，请求消息可用于请求定位参考信号的测量信息。又例如，终端设 备确定满足第一条件和第二条件，请求消息可用于请求激活预配置的测量信息中的至少一套测量信息。应理解，“预配置”指的是接入网设备提前将定位参考信号相关的测量信息发送给终端设备或定位管理设备。终端设备或定位管理设备可以根据需求向接入网设备请求激活预配置的测量信息或请求去激活测量信息。相应的，接入网设备响应终端设备或定位管理设备的请求，可通过信令或消息进行激活。或者，终端设备或定位管理设备可以根据需求向接入网设备请求去激活已经配置的或者已经激活成功的测量信息，相应的，接入网设备响应终端设备或定位管理设备的请求，可通过信令或消息进行去激活。
在本申请实施例中，第一条件和/或第二条件可以认为是终端设备向接入网设备请求激活预配置的测量信息或请求测量信息的触发条件。终端设备确定满足第一条件和/或第二条件，才向接入网设备请求激活预配置的测量信息或请求测量信息，从而，可以避免在不满足触发条件发送请求消息，可以提高获取测量信息的成功率，并提高测量性能。
第二方面，提供了一种通信方法可由第一通信装置执行，第一通信装置可以是终端设备，或者该第一通信装置为能够支持终端设备实现该方法所需的功能的通信装置，例如芯片系统。应理解，芯片系统可设置在终端设备中。下面以第一通信装置为终端设备为例进行描述。该方法包括：
终端设备确定满足第三条件，发送请求消息。请求消息用于请求定位参考信号的测量信息。测量信息包括PPW配置信息，或者，测量信息包括MG配置信息和PPW配置信息。其中，第三条件为定位参考信号的测量信息未被配置，或者，第三条件为定位参考信号的测量信息不满足终端设备的测量需求。也可以理解为，第三条件为网络未配置或未激活定位参考信号的测量信息，或者，网络配置或激活的定位参考信号的测量信息不满足终端设备的测量需求。也可以理解为，终端设备发送请求消息之前，可判断是否满足第三条件。当终端设备确定满足第三条件，发送请求消息。
在本申请实施例中，第三条件可以认为是终端设备向接入网设备请求测量信息的触发条件。终端设备确定满足第三条件，才向接入网设备请求测量信息，从而，可以避免在不满足触发条件向接入网设备请求测量信息，可以提高获取测量信息的成功率，并提高测量性能。
在可能的实现方式中，终端设备发送请求消息之前，可判断是否满足第一条件和/或第二条件，或者，判断是否满足第三条件。也可以理解为，第一条件和/或第二条件为条件A，第三条件为条件B，终端设备发送请求消息之前，可判断是否满足条件A或条件B。
第三方面，提供了一种通信方法可由第一通信装置执行，第一通信装置可以是终端设备，或者该第一通信装置为能够支持终端设备实现该方法所需的功能的通信装置，例如芯片系统。应理解，芯片系统可设置在终端设备中。下面以第一通信装置为终端设备为例进行描述。该方法包括：
终端设备确定满足第四条件和/或第五条件，发送请求消息。该请求消息用于请求去激活至少一套测量信息，例如，该请求消息用于请求去激活已配置的测量信息中的至少一套测量信息，或者，该请求消息用于请求去激活已经激活的测量信息中的至少一套测量信息。所述测量信息为定位参考信号的测量信息，包括MG配置信息和/或PPW配置信息。其中，第四条件为接收到停止或结束执行测量的消息，或者，不再需要测量信息，也可以理解为，第四条件为不再需要已经配置的测量信息或已经激活的测量信息。第五条件为当前存在激活的测量信息，或者，测量信息被允许请求去激活，也可以理解为，第五条件为允许终端 设备请求去激活已经配置或已经激活成功的测量信息。应理解，终端设备不使用已经“去激活”成功的测量信息。也可以理解为，终端设备发送请求消息之前，可判断是否满足第四条件和/或第五条件。当终端设备确定满足第四条件，即终端设备不需要已配置或已激活的测量信息，从而，终端设备请求去激活某些测量信息，可释放网络资源，提高资源利用率，并且降低终端的测量复杂度。当终端设备确定第五条件，终端设备可发送去激活请求，以降低定位时延；终端设备确定不满足第五条件，终端设备可发送去激活请求。
在本申请实施例中，第四条件和/或第五条件可以认为是终端设备发送去激活请求的触发条件。终端设备确定满足第四条件和/或第五条件，才发送请求去激活测量信息。从而，可以避免在不满足触发条件向接入网设备发起去激活请求，可以提高去激活请求成功率，并避免网络资源的浪费。
在第一方面或第二方面可能的实现方式中，终端设备确定定位参考信号的测量信息可用或已配置了定位参考信号的测量信息，且定位参考信号的测量信息满足终端设备的测量需求，终端设备执行定位测量。也就是，终端设备确定不满足第三条件，终端设备执行定位测量。终端设备在执行定位测量之前，可判断是否满足第三条件，如果满足第三条件，则向接入网设备请求定位参考信号的测量信息；如果不满足第三条件，则可执行定位测量，无需请求定位参考信号的测量信息，从而降低定位时延。
在第一方面或第二方面可能的实现方式中，所述测量信息包括MG配置信息和PPW配置信息，终端设备可基于MG配置信息执行定位测量，且不基于PPW配置信息执行定位测量。也可以理解为，基于MG配置信息执行定位测量的优先级高于基于PPW配置信息执行定位测量的优先级。从而在网络配置或激活MG配置信息和PPW配置信息的情况下，终端设备优先使用MG配置信息。可以理解的是，如果接入网设备配置了或者激活了MG配置信息，说明接入网设备已经完成相关资源调度和配置等操作。如此，终端设备使用MG的配置信息执行定位测量，即采用测量间隙进行测量，无需考虑定位参考信号和其它参考信号以及数据之间的测量优先级顺序，可以降低终端设备的处理复杂度。
在可能的实现方式中，所述测量信息包括MG配置信息和PPW配置信息，终端设备可基于PPW配置信息执行定位测量，且不基于MG配置信息执行定位测量。这样终端设备在执行定位测量时，在PPW的时长内，终端设备也可以测量或处理除定位参考信号之外的其它参考信号和数据，从而可以降低定位对通信的影响。
在第一方面或第二方面可能的实现方式中，终端设备确定满足第三条件，且不满足第一条件，向接入网设备发送请求消息。该请求消息用于请求定位参考信号的测量信息，也可以理解为，该请求消息用于请求网络配置定位参考信号的测量信息。当终端设备确定满足第三条件，不满足第一条件，也就是，网络没有预配置测量信息的情况下，终端设备确定网络还未配置测量信息或未激活预配置的测量信息，或者终端设备确定网络配置或激活的测量信息不满足测量需求的情况下，终端设备可请求网络配置测量信息。
在第一方面或第二方面可能的实现方式中，所述测量信息包括MG配置信息和PPW配置信息，请求消息可请求PPW配置信息，而不请求MG配置信息。也可以理解为，PPW配置信息的请求优先级高于MG配置信息的请求优先级。应理解，基于PPW配置信息测量是不基于测量间隙MG进行测量，在PPW的时长内，终端设备也可以测量或处理除定位参考信号之外的其它参考信号和数据，对通信数据传输的影响较小。通过本申请实施例提供的方法，即优先请求PPW的配置信息，可以降低对通信数据传输的影响。
在可能的实现方式中，所述测量信息包括MG配置信息和PPW配置信息，请求消息可请求MG配置信息，而不请求PPW配置信息。通过本申请实施例提供的方法，即优先请求MG配置信息，可以优先保证定位测量性能，降低终端设备的处理复杂度。
在第一方面或第二方面可能的实现方式中，终端设备确定满足第一条件和第三条件，向接入网设备发送请求消息。该请求消息用于请求激活预配置的定位参考信号的测量信息。当终端设备确定满足第一条件和第三条件的情况下，可认为请求网络激活预配置的测量信息的优先级高于请求网络配置测量信息的优先级。即在网络预配置了测量信息的情况下，终端设备确定网络还未配置测量信息或未激活预配置的测量信息，或者终端设备确定网络配置或激活的测量信息不满足测量需求的情况下，终端设备可优先请求激活网络配置测量信息。
进一步地，如果终端设备确定满足第二条件，终端设备可基于MAC CE信令请求激活预配置的测量信息，以降低定位时延；终端设备确定不满足第二条件，终端设备可基于RRC信令请求激活预配置的测量信息。
在第一方面或第二方面可能的实现方式中，所述测量信息包括MG的配置信息和PPW的配置信息，请求消息可请求激活预配置的PPW配置信息，而不请求激活预配置的MG配置信息。也可以理解为，预配置的PPW配置信息的请求激活优先级高于预配置的MG配置信息的请求激活优先级。优先请求激活预配置的PPW配置信息，优先使用PPW的配置信息，可降低对通信数据传输的影响。
在第一方面或第二方面可能的实现方式中，所述预配置的测量信息包括预配置的MG配置信息和预配置的PPW配置信息，请求消息可请求激活预配置的MG配置信息，而不请求激活预配置的PPW配置信息，以优先保证定位测量性能，降低终端设备的处理复杂度。
在第一方面至第三方面的任一方面的可能的实现方式中，终端设备在发送请求消息时，可启动第一定时器终端设备。或者，终端设备在发送请求消息之后，可启动第一定时器。在终端设备发送请求消息后的一段时间内(例如第一定时器工作期间)，终端设备无需再次发送请求消息，从而可避免频繁地发送请求消息，降低终端设备的能耗。
在可能的实现方式中，终端设备在接收到响应消息时或在接收到响应消息之后，停止第一定时器。该响应消息为请求消息的响应消息。例如，所述响应消息为配置测量信息的消息，或者，所述响应消息为激活预配置测量信息的消息。可以理解的是，如果终端设备接收到响应消息，就能获取测量信息，从而无需继续等待定时器，可停止定时器。
在可能的实现方式中，第一定时器包括如下的一项或多项参数：第一定时时长，请求消息的最大发送次数，或测量信息的最多请求套数。第一定时器的参数可以是预定义的，或者由网络预配置或配置。第一定时时长，可以理解为，第一定时器从启动(start)到到期(expire)之间的时长。请求消息的最大发送次数，可以理解为，允许终端设备发送请求消息的最大次数。类似的，测量信息的最多请求套数，可以理解为，允许终端设备请求测量信息的最多套数。终端设备在不同时刻发送的请求消息所请求的测量信息可以不相同。例如，终端设备在第一时刻发送第一请求消息，该第一请求消息请求第一测量信息，终端设备在第二时刻发送第二请求消息，该第二请求消息请求第二测量信息。第一测量信息和第二测量信息可以不同。
可选地，当第一定时器启动之后，累计终端设备发送请求消息的次数；可选地，当第 一定时器启动之后，累计终端设备请求的测量信息的套数；可选地，当第一定时器启动之后，累计终端设备发送请求消息的次数，并累计终端设备请求的测量信息的套数。
值得注意的是，第一定时器“结束”和第一定时器“停止”的条件或情况是不同的。当累计终端设备发送请求消息的次数达到所述请求消息的最大发送次数，第一定时器结束。当累计终端设备请求的测量信息的套数达到所述测量信息的最多请求套数，第一定时器结束。当累计终端设备发送请求消息的次数达到所述请求消息的最大发送次数，并且累计终端设备请求的测量信息的套数达到所述测量信息的最多请求套数，第一定时器结束。当第一定时器的持续时间达到第一定时时长，第一定时器停止。在终端设备接收到响应消息时或在接收到响应消息之后，第一定时器结束。此时，终端设备可判断网络是否配置了测量信息或激活了测量信息，或者判断网络配置或激活的测量信息是否满足测量需求，进而基于判断结果确定是否发送请求消息。
在第一方面至第三方面的任一方面可能的实现方式中，在预设时长内没有接收到所述响应消息，终端设备可发送失败消息。该失败消息可指示获取测量信息失败或定位测量失败。通过该方法可明确告知网络终端设备没有获取到测量信息或定位结果。可选地，后续网络可以为终端设备重新配置测量信息，以尽量提高终端设备获取测量信息的成功率。可选地，该失败消息可指示获取测量信息失败的原因，为网络重新配置测量信息提供参考。
在第一方面至第三方面的任一方面的可能的实现方式中，终端设备在发送请求消息之前，可以启动第二定时器。通过第二定时器给接入网设备预留一定的时间配置测量信息或者激活预配置的测量信息。这样，在终端设备确定需要执行定位测量后的一段时间内(例如第二定时器工作期间)，如果网络设备配置了测量信息或者激活了预配置的测量信息，则终端设备无需发送请求消息。通过该方案，可避免终端设备发送不必要的请求消息或过早发送请求消息，能够有效降低定位时延。
在可能的实现方式中，终端设备在接收到响应消息时或在接收到响应消息之后，停止第二定时器。该响应消息可为网络配置测量信息的消息，或者，该响应消息为网络激活预配置的测量信息的消息。
在可能的实现方式中，第二定时器的参数可以是预定义的，或者由网络设备预配置或配置，例如，可预定义或预配置或配置第二定时器的最长持续时长，即第二定时时长。

具体实施方式
为方便理解本申请各个实施例提供的技术方案，首先对本申请实施例涉及的部分技术术语进行解释说明。
1)(无线)接入网设备(radio access network，(R)AN)，也可以称为接入设备，(R)AN能够管理无线资源，为用户设备提供接入服务，完成用户设备数据在用户设备和核心网之间的转发，(R)AN也可以理解为网络中的基站。
示例性的，本申请实施例中的接入网设备可以是用于与用户设备通信的任意一种具有无线收发功能的通信设备。该接入网设备，例如包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(home evolved NodeB，HeNB，或home Node B，HNB)、基带单元(baseBand unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如NR系统中的下一代节点B(next generation node B，gNB)，或传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或分布式单元(distributed unit，DU)等。在基于5G核心网的定位架构中，gNB/ng-eNB可以为目标用户设备提供测量信息，并将此信息传达给定位管理设备。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、MAC层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。RRC层的信息由CU生成，最终会经过DU的PHY层封装变成PHY层信息，或者，由PHY层的信息转变而来。因而，在这种架构下，高层信令如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，接入网设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的接入网设备，也可以将CU划分为核心网(core network，CN)中的接入网设备，接入网设备可以是下一代无线接入网(next-generation radio access network，NG-RAN)本申请对此不做限定。
本申请实施例中，用于实现接入网设备的功能的装置可以是接入网设备，也可以是能够支持接入网设备实现该功能的装置，例如芯片系统，该装置可以被安装在接入网设备中。在本申请实施例提供的技术方案中，以用于实现接入网设备的功能的装置是接入网设备为例进行描述。
2)终端设备，也可以称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。例如，所述终端设备可以包括具有无线连接功能的手持式设备、车载设备等。目前，所述终端设备可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)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，或智慧家庭(smart home)中的无线终端等。
作为示例而非限定，在本申请的实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。终端设备还可以包括中继(relay)，例如，终端设备可以是客户终端设备(customer premise equipment，CPE)，CPE可接收来自网络设备的信号，并将该信号转发给其他终端设备。或者理解为，能够与基站进行数据通信的都可以看作终端设备。如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
另外，本申请实施例中，终端设备可以是指用于实现终端设备的功能的装置，也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中。例如终端设备也可以是车辆探测器。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端设备的功能的装置是终端设备为例进行描述。
3)定位管理设备，也称为位置管理网元，主要负责定位管理。例如，定位管理设备 如接收其他网元(如接入与移动性管理网元)的定位请求，并对用户的定位数据进行收集，通过定位计算后获得用户位置。位置管理网元还可以对基站或定位管理单元进行管理和配置，实现定位参考信号的配置等。本申请实施例对定位管理设备的名称不作限定，例如，定位管理设备也可以称为定位设备、位置服务器、定位服务中心或定位处理中心等。本申请实施例涉及的定位管理设备可为位置管理功能(location management function，LMF)或者位置管理组件(location management component，LMC)，或者可以是位于接入网设备中的本地位置管理功能(local location management function，LLMF)，或者其它具有类似功能的网元等。为了方便描述，下述实施例均以定位管理设备为LMF为例进行介绍。
在基于5G核心网的定位架构中，LMF网元的作用可以是负责支持有关目标UE的不同类型的位置服务，包括对UE的定位和向UE传递辅助数据，其控制面和用户面分别是演进服务移动定位中心(evolved serving mobile location centre，E-SMLC)和服务定位协议(service location protocol，SLP)。LMF网元可以与ng-eNB/gNB和UE进行如下的信息交互：
与下一代演进型基站(next generation evolved nodeB，ng-eNB)/gNB之间通过NR定位协议A(NR positioning protocol A，NRPPa)消息进行信息交互，例如获取PRS、探测参考信号(sounding reference signal，SRS)配置信息、小区定时、小区位置信息等；
与UE之间通过LTE定位协议(LTE positioning protocol，LPP)消息进行UE能力信息传递、辅助信息传递、测量信息传递等。
4)定位方法，根据定位参考信号(positioning reference signal，PRS)的来源，定位方法分为以下三类：下行定位方法、上行定位方法以及上下行联合定位方法。需要说明的是，这里上行和下行是相对而言的，如果网络设备到终端设备的传输方向为下行(本文以此为例)，那么终端设备到网络设备的传输方向为上行。相反，如果网络设备到终端设备的传输方向为上行，那么终端设备到网络设备的传输方向为下行。
下行定位方法，终端设备对网络侧发送的下行定位参考信号(downlink positioning reference signal，DL-PRS)进行测量。终端设备根据测量结果估计终端设备的位置，实现下行定位。
上行定位方法，网络设备对终端设备发送的上行定位参考信号(uplink positioning reference signal，UL-PRS)进行测量。网络设备根据测量结果估计终端设备的位置，实现上行定位。上行定位参考信号可以是SRS，或者其他可用于上行测量的参考信号。本申请实施例对此并不进行限定。例如，SRS可以为用于多输入多输出(multiple-input multiple-out-put，MIMO)的上行参考信号(MIMO-SRS)。SRS也可以为专用于定位的上行定位参考信号(pos-SRS)。
上下行联合定位方法，网络设备对来自终端设备的上行定位信号进行测量，以及终端设备对来自网络设备下行定位参考信号进行测量。基于网络设备的测量结果和终端设备的测量结果估计终端设备的位置。
5)定位参考信号(positioning reference signal，PRS)的测量配置信息，包括MG的配置信息和PPW的配置信息。本文中PPW的配置信息也称为测量处理窗配置信息。
可以理解的是，如果终端设备只有一套射频通路，那么不支持在服务小区上收发信号的同时在异频领区上接收信号。换句话说，如果终端设备使用一个射频模块来执行测量、收发信号，那么终端设备不支持同时工作在两个异频频点。这种情况下，终端设备需要采 用间隙(gap)测量的方式测量异频频点上所接收的信号。终端设备在gap内停止服务小区上的信号收发，将射频通路调整至异频频点上，接收异频邻区的信号。gap时间结束后，射频通路切换到当前小区频点。
gap可以由网络设备配置，也就是网络设备可以配置MG。MG的配置参数包括如下的一项或多项：测量间隔重复周期(measurement gap repetition period，MGRP)、测量偏移(gapOffset)、测量长度(measurement gap length，MGL)，或测量定时提前(measurement gap timing advance，MGTA)。其中，MGRP用于配置gap的周期，例如为4ms、20ms、80ms或160ms。gapOffset用于配置gap的起始位置。从周期内的起始子帧开始，测量偏移的取值集合为{0,1,…,MGRP-1}。例如，MGRP＝160ms，测量偏移有160个取值。又例如，MGRP＝20ms，测量偏移的取值集合为{0,1,…,19}。MGL用于配置gap的长度，例如，MGL可为1.5ms、3ms、3.5ms、4ms、5.5ms或6ms。如果配置MGTA，测量gap在gap子帧出现之前开始测量MGTA ms，即测量gap从时间间隙ms提前到最新子帧出现之前结束。MGTA为0.25ms或0.5ms。
如上所示，终端设备在gap内会停止服务小区上的信号收发，为此，引入PPW，即基于无gap进行PRS的测量。这样终端设备可以不用中止测量服务基站发送的PRS，以提高定位性能。在PPW内，可以根据终端设备的能力确定PRS和其它信号及通信数据的优先级，例如终端设备可以优先处理PRS。接入网设备可配置PPW，PPW的配置参数可包括如下的一项或多项：起始位置(例如起始时隙)、周期、长度、所关联的小区(cell)和子载波间隔(sub-carrier space，SCS)，或者是否支持其他参数(例如优先级、频段，或者分量载波(component carrier，CC)。
6)“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示44.前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这十多个些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一条件和第二条件，只是为了区分不同的条件，而并不是表示这两种条件的优先级、发送顺序或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些技术术语，下面介绍本申请实施例相关的内容。
终端设备需要执行定位测量时，可向接入网设备请求相应的测量配置。或者，定位管理设备向接入网设备请求相应的测量配置。接入网设备响应终端设备或定位管理设备的请求，向终端设备发送与请求相应的测量配置，以用于终端设备进行定位测量。
例如，如果终端设备接收到定位管理设备发送的关于观察到达时间差(observed time difference of arrival，OTDOA)的系统间移动性控制(Inter-RAT)参考信号定时差(reference signal time difference，RSTD)测量或NR DL-PRS测量。终端设备确定需要测量MG来执 行定位测量。如果网络配置了MG的配置信息且该MG的配置信息满足终端设备的测量需求，那么终端设备可执行位置测量或目标E-UTRA系统的子帧和时隙时序获取过程。如果网络没有配置MG配置信息或者已经配置的MG配置信息不满足终端设备的测量需求，或者，终端设备需要获取目标E-UTRA系统的子帧和时隙时序时，终端设备可通过RRC信令向接入网设备发送位置测量指示(location measurement indication)，以请求MG配置信息。位置测量指示可指示终端设备将开始位置测量，或者终端设备将获取目标演进的通用移动通信系统(universal mobile telecommunications system，UMTS)陆地无线接入(eolved universal terrestrial radio access，E-UTRA)系统的子帧和时隙时序。该位置测量指示包括用于请求接入网设备MG配置信息。当终端设备根据获取的MG配置完成定位之后，终端设备可向接入网设备发送另一个位置测量指示，以指示终端设备已经完成位置测量或者完成目标E-UTRA系统的子帧和时隙时序获取过程。
为了降低定位时延，目前提出接入网设备可通过RRC信令预配置定位参考信号的测量信息。例如，可预配置MG配置信息和/或PPW配置信息。在预配置MG配置信息和PPW配置信息的情况下，终端设备沿用目前请求MG配置信息的流程显然不适用。即针对预配置定位参考信号的测量信息的情况，终端设备如何执行定位测量，还没有相应的方案。
鉴于此，提供本申请实施例的方案。针对预配置MG配置信息和PPW配置信息的情况，本申请实施例为终端设备执行定位测量提供了一种可行的方案。
本申请实施例提供的方案可以应用于各种通信系统，例如：LTE系统、5G系统，如新无线(new radio，NR)系统，或下一代的通信系统，如6G系统等。当然，本申请实施例的技术方案也可以应用于其它的通信系统，只要该通信系统存在对终端的定位需求即可。此外，所述通信系统还可以适用于面向未来的通信技术，本申请实施例描述的系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
图1为本申请实施例适用的一种通信系统的定位架构的示意图，如图1所示，涉及的网元/模块主要包括下一代无线接入网络(next generation radio access network，NG RAN)、终端设备和核心网三部分。其中，核心网包括LMF、接入和移动性管理功能(access and mobility management function，AMF)、SLP以及E-SMLC等。定位服务器即定位管理功能(location management function，LMF)连接到AMF，LMF和AMF之间通过NLs接口连接。LMF负责支持有关终端的不同类型的位置服务，包括对终端的定位和向终端传递辅助数据。AMF可以从第5代核心网络定位服务(5th generation core network location services，5GC LCS)实体接收与终端相关的位置服务请求，或者AMF本身也可代表特定终端启动一些位置服务，并将位置服务请求转发给LMF。得到终端返回的位置信息后，将相关位置信息返回给5GC LCS实体。
NG RAN可以包括下一代节点B(next generation node B，gNB)、下一代演进型基站(next generation evolved nodeB，ng-eNB)或者未来演进的网络节点等。gNB、ng-eNB之间通过Xn接口连接，LMF与ng-eNB/gNB通过NG-C接口连接。
应理解，上述图1是本申请实施例可适用的通信系统的一种示例性说明，并不对本申请适用的通信系统所包括网元的类型、数量、连接方式等进行具体限定。
例如，图2示出了本申请实施例适用的一种通信系统的网络架构，该通信系统包括核 心网、NG-RAN和终端。核心网包括LMF、AMF、安全用户平面定位(secure user plane location，SUPL)定位平台(SUPL location platform，SLP)以及E-SMLC等网元/模块，NG RAN包括gNB、ng-eNB等网元/模块，其中LMF、AMF、SLP、E-SMLC、gNB以及ng-eNB等网元/模块的具体功能、各个网元/模块之间的连接关系可以参见上文图2相关部分的介绍，这里不再赘述。
与图1不同的是，图2所示的网络架构中NG-RAN中增加了LMC，LMC的具体部署方式是设置在基站内部，如设置在gNB中或设置在ng-ENB中。在这种网络架构中，LMC作为是基站内部的一个功能，因此不需要引入新的接口。
图3示出了本申请实施例适用的另一种通信系统的网络架构，如图3所示，通信系统同样包括核心网、NG-RAN和终端。与图2不同的是，图3所示的网络架构中的LMC在NG-RAN中作为一个独立的逻辑节点，通过一个新接口与基站相连接，例如图3中，LMC通过接口Itf与gNB-CU相连。
图4示出了本申请实施例适用的再一种通信系统的网络架构，如图4所示，通信系统同样包括核心网、NG-RAN和终端，LMC在NG-RAN中作为一个独立的逻辑节点，与图3不同的是，LMC可以图4经过新接口同时与多个基站连接。图4以LMC与两个基站同时相连为例，在具体实施时LMC还可以与更多的基站相连。
上述图1-图4是本申请实施例可适用的通信系统的一种示例性说明，并不对本申请适用的通信系统所包括网元的类型、数量、连接方式等进行具体限定。且图1-图4中虚线示意的网元/模块不是不必可少的，是可选的，例如E-SMLC或SLP不是必不可少的；或者，虚线示意的网元/模块是另一种存在形式，例如gNB或ng-eNB在一些实施例中也称为TRP，终端设备在一些实施例称为安全用户平面定位(secure user plane location，SUPL)使能终端(SUPL enabled terminal，SET)。
本申请实施例提供的通信方法可应用于终端设备的定位。例如，上行定位、下行定位和上下行定位。需要说明的是，这里上行和下行是相对而言的，如果网络设备到终端设备的传输方向为下行(本文以此为例)，那么终端设备到网络设备的传输方向为上行；相反，如果网络设备到终端设备的传输方向为上行，那么终端设备到网络设备的传输方向为下行。
下面结合附图对本申请实施例提供的方案进行详细介绍。需要说明的是，在本申请的各个实施例对应的附图中，凡是用虚线表示的步骤均为可选的步骤。本申请实施例以定位参考信号的测量为例，但是并不限于定位参考信号，也就是，本申请实施例也可以适用于其他参考信号的测量。其他参考信号，例如包括同步信号和物理广播信道块(synchronization signal and PBCH block，SSB)。在上行定位中，“定位参考信号”也称为“上行参考信号”、“上行定位参考信号”等。在下行定位中，“定位参考信号”也称为“下行参考信号”、“下行定位参考信号”等。也可以理解为，“上行参考信号”、“上行定位参考信号”和“定位参考信号”都代表用于定位的上行参考信号。“下行参考信号”、“下行定位参考信号”和“定位参考信号”都代表用于定位的下行参考信号。在下文中不明确区分。
为方便描述，下文中将定位参考信号的测量信息简称为测量信息。也就说，本申请实施例中的测量信息均指定位参考信号的测量信息。相应的，预配置的定位参考信号的测量信息，可称为预配置的测量信息。预配置的测量信息，也可以称为预配置测量信息。网络可预配置一套测量信息，也可以预配置多套测量信息，即预配置的测量信息包括至少一套 测量信息。一套测量信息可包括一个或多个测量参数。例如，测量信息，例如包括MG配置信息和/或PPW配置信息，那么测量参数，例如包括MG/PPW的偏移量、开始时隙、持续时间、周期、MG的定时提前信息、PPW的小区和子载波间隔信息等，具体可参考前述技术术语5)中的相关内容，此处不再赘述。
下文中，请求消息用于请求测量信息，指的是请求网络配置测量信息。网络配置测量信息，可以是网络发送临时配置的测量信息，也可以是，网络指示激活预配置的测量信息，或者，网络指示去激活的测量信息。针对请求激活预配置测量信息的情况，请求消息可用于请求激活预配置的一套或多套测量信息，和/或，预配置的一个或多个测量参数。针对请求去激活测量信息的情况，请求消息可用于请求去激活一套或多套测量信息，和/或，一个或多个测量参数。
在下文的介绍过程中，以该方法应用于图1-图4中任一所示的通信系统为例。需要说明的是，本申请实施例只是以通过图1-图4的通信系统为例，并不限制于这种场景。另外，该方法涉及接入网设备和终端设备，还可能涉及定位管理设备等，在下文中，以定位管理设备是LMF网元为例，应理解，在未来通信如6G中，定位管理设备仍可以是LMF网元，或有其它的名称，本申请实施例不作限定。另外，接入网设备可以是当前为终端设备服务的接入网设备。该接入网设备可以是NG RAN中的设备，例如gNB、ng-eNB。或者，该接入网设备可以是LMC。如前文所述，如果LMC作为接入网设备内部的一个功能，那么该接入网设备为LMC所在的接入网设备。如果LMC的部署方案如图3或图4，即LMC作为一个独立的逻辑节点通过接口与一个网络设备或多个接入网设备连接，那么该接入网设备为与LMC连接的任意一个接入网设备。下文以本申请实施例提供的通信方法应用于下行定位为例。
终端设备需要执行定位测量时，可向接入网设备请求配置定位参考信号的测量信息。如果接入网设备预配置了定位参考信号的测量信息，终端设备也可以向接入网设备请求激活预配置的定位参考信号的测量信息。如果不再需要已配置的或已激活的测量信息，终端设备也可以向接入网设备发送去激活请求。
本申请实施例针对预配置MG配置信息和/或PPW配置信息的情况，为终端设备执行定位测量提供了一种可行的方案。例如，为终端设备向网络请求定位参考信号的测量信息设置了触发条件。即触发条件可以认为是触发终端设备向网络发送请求消息的条件。终端设备在确定满足触发条件时，才向网络请求定位参考信号的测量信息。也就是，终端设备在向网络请求定位参考信号的测量信息之前，可判断是否满足触发条件。如果满足触发条件，则向网络请求定位参考信号的测量信息，从而提高终端设备获取测量信息的成功率。需要说明的是，终端设备向网络请求定位参考信号的测量信息，可以是终端设备直接向接入网设备请求定位参考信号的测量信息，也可以通过定位管理设备向接入网设备请求定位参考信号的测量信息，对此，本申请实施例不作限制。下文以终端设备直接向接入网设备请求定位参考信号的测量信息为例。需要说明的是，本申请实施例以终端设备执行定位测量为例，但是本申请实施例也可以适用于其他用于执行定位测量的设备。
触发条件可包括第一条件、第二条件和第三条件中的至少一种条件。其中，第一条件为预配置的测量信息可用，且所预配置的测量信息中的至少一套测量信息满足终端设备的测量需求。预配置的测量信息可用，也可以理解为，预配置了测量信息。例如，接入网设 备预配置了可用的M套测量信息，这M套测量信息中的N套测量信息可用。第二条件为预配置的测量信息中的至少一套测量信息被允许通过MAC CE信令请求激活。也可以理解为，第二条件为接入网设备允许终端设备通过MAC CE信令请求激活预配置的测量信息。或者说，第二条件为预配置的测量信息中的至少一套测量被允许通过MAC CE信令激活。第三条件为测量信息未被配置，也可理解为，接入网设备未配置测量信息。或者，第三条件为测量信息不满足终端设备的测量需求，也可理解为，接入网设备配置的测量信息不满足测量终端设备的测量需求。例如，MG配置中的测量窗与PRS的发送窗口时机不匹配，可认为，接入网设备配置的测量信息不满足测量终端设备的测量需求。又例如，已经为无线资源管理(radio resource management，RRM)测量配置的MG不足以用于定位测量，也可认为，接入网设备配置的测量信息不满足测量终端设备的测量需求。又例如，MG的周期与PRS的周期没有对齐，也可认为，接入网设备配置的测量信息不满足测量终端设备的测量需求。此处仅列举了接入网设备配置的测量信息不满足测量终端设备的测量需求的几种情况，本申请实施例对不满足测量终端设备的测量需求的测量信息的具体配置不作限制。
终端设备确定满足触发条件，发送请求消息，以请求测量信息。例如，请求网络配置测量信息，或者，请求网络指示激活的测量信息，或者，请求网络激活预配置的测量信息。根据触发条件的不同，请求消息的功能也有所不同。下面以具体的示例进行说明。
示例1，触发条件为第一条件。
终端设备确定满足第一条件，向接入网设备发送请求消息。即接入网设备预配置了可用的测量信息，且预配置的测量信息满足终端设备的测量需求时，终端设备可发起请求消息。在一种可能的实现方式中，该请求消息可用于请求接入网设备激活预配置的测量信息，无需向接入网请求配置测量信息，从而可降低定位时延。在另一种可能的实现方式中，请求消息可用于请求预配置的测量信息中的至少一套测量信息，能够提高请求的成功率。终端设备在执行定位测量之前，可判断是否满足第一条件，如果满足第一条件，则向接入网设备请求激活预配置的测量信息。
例如，当接入网设备预配置了MG配置信息和PPW配置信息，终端设备可以向接入网设备请求激活预配置的MG配置信息中的至少一套MG配置信息，也可以向接入网设备请求激活预配置的PPW配置信息中的至少一套PPW配置信息。在本申请实施例中，终端设备可以按照预配置或配置的优先级顺序确定请求激活MG配置信息或请求激活PPW配置信息。
一种可能的优先级顺序为：PPW配置信息的请求激活优先级高于MG配置信息的请求激活优先级。也就是，终端设备请求激活PPW配置信息，不请求激活MG配置信息。由于基于PPW配置信息测量是无测量间隙的测量，在PPW的时长内，终端设备也可以测量或处理除定位参考信号之外的其它参考信号和数据，所以，优先请求激活PPW配置信息，可以降低定位对通信的影响。
另一种可能的优先级顺序为：MG配置信息的请求激活优先级高于PPW配置信息的请求激活优先级。也就是，终端设备请求激活MG配置信息，不请求激活PPW配置信息。由于基于MG配置信息的测量是采用测量间隙进行的测量，无需考虑定位参考信号和其它参考信号以及数据之间的测量优先级顺序，所以优先请求激活MG配置信息，可以降低终端设备的处理复杂度。
接入网设备响应于终端设备的请求消息，可向终端设备发送该请求消息的响应消息。 该响应消息可指示激活的测量信息。如果接入网设备为终端设备激活的测量信息包括MG配置信息和PPW配置信息，终端设备也可以按照预配置或配置的优先级顺序确定使用MG配置信息或PPW配置信息。
一种可能的优先级顺序为：MG配置信息的使用优先级高于PPW配置信息的请求优先级。也就是，终端设备可基于MG配置信息执行定位测量，且不基于PPW配置信息执行定位测量。可以理解的是，接入网设备配置了或者激活了MG配置信息，接入网设备已经完成相关资源调度和配置等操作。因此终端设备使用MG配置信息执行定位测量，可以降低终端设备的处理复杂度。
另一种可能的优先级顺序为：PPW配置信息的使用优先级高于MG配置信息的请求优先级。也就是，终端设备可基于PPW配置信息执行定位测量，且不基于MG配置信息执行定位测量，以降低定位对通信的影响。
示例2，触发条件为第二条件。
终端设备确定满足第二条件，向接入网设备发送请求消息，该请求消息可用于请求激活预配置的测量信息中的至少一套测量信息，或者，该请求消息用于请求测量信息。终端设备在执行定位测量之前，可以判断是否满足第二条件，以确定基于何种方式向终端设备发送请求消息。例如，终端设备确定满足第二条件，即接入网设备允许终端设备通过MAC CE信令发送请求消息，则终端设备通过MAC CE信令发送请求消息，例如请求激活预配置的测量信息中的至少一套测量信息，以尽量降低定位时延。相反，如果终端设备确定不满足第二条件，即接入网设备不允许终端设备通过MAC CE信令发送请求消息，则一种可能的实现方式是，终端设备可基于RRC信令发送请求消息，例如请求激活预配置的测量信息中的至少一套测量信息，或者，直接向网络请求配置测量信息。
例如，当终端设备既可以向接入网设备请求MG配置信息，又可以向接入网设备请求PPW配置信息时，终端设备可以按照预配置或配置的优先级顺序确定请求MG配置信息或PPW配置信息。
一种可能的优先级顺序为：PPW配置信息的请求优先级高于MG配置信息的请求优先级。也就是，终端设备请求PPW配置信息，不请求MG配置信息，以降低定位对通信的影响。
另一种可能的优先级顺序为：MG配置信息的请求优先级高于PPW配置信息的请求优先级。也就是，终端设备请求MG配置信息，不请求PPW配置信息，以降低终端设备的处理复杂度。
示例3，触发条件为第三条件，终端设备确定满足第三条件，向接入网设备发送请求消息。该请求消息可用于请求接入网设备配置测量信息。即终端设备确定接入网设备没有配置测量信息，或者接入网设备配置的测量信息或激活的测量信息不满足终端设备的测量需求，终端设备向接入网设备请求配置测量信息，以执行定位测量。
终端设备在执行定位测量之前，可判断是否满足第三条件，如果满足第三条件，则向接入网设备请求定位参考信号的测量信息。与示例2类似，当终端设备既可以向接入网设备请求MG配置信息，又可以向接入网设备请求PPW配置信息时，终端设备可以按照预配置或配置的优先级顺序确定请求MG配置信息或PPW配置信息。具体参考示例2的相关内容，此处不再赘述。
如果终端设备确定不满足第三条件，终端设备可执行定位测量。也就是，终端设备确 定接入网设备配置或激活了测量信息，且配置或激活的定位参考信号的测量信息满足终端设备的测量需求，终端设备可执行定位测量，无需请求定位参考信号的测量信息，从而降低定位时延。与示例1类似，如果接入网设备为终端设备配置了MG配置信息和PPW配置信息，终端设备可以按照预配置或配置的优先级顺序确定使用MG配置信息或PPW配置信息。具体可参考示例1的相关内容，这里不再赘述。
示例4，触发条件包括第一条件和第三条件。例如，终端设备确定满足第三条件，不满足第一条件，向接入网设备发送请求消息，该请求消息可用于请求配置测量信息。终端设备在执行定位测量之前，可判断是否满足第三条件，在确定满足第三条件的情况下，终端设备可继续判断是否满足第一条件。如果终端设备确定满足第一条件，终端设也可以发送请求消息，该请求消息可用于请求激活预配置的测量信息，或者，该请求消息也可以用于请求测量信息。即满足第一条件和第三条件也可以认为是一种触发条件。相反，如果终端设备确定不满足第一条件，则向接入网设备发送请求消息，以请求接入网设备配置测量信息。也就是，终端设备在如下的任一种情况，向接入网设备发送请求消息。
情况1，终端设备确定未配置测量信息，且，终端设备确定未预配置测量信息或预配置的测量信息不可用，则发送请求消息。
情况2，终端设备确定已配置的测量信息或激活的测量信息不满足终端设备的测量需求，且，终端设备确定未预配置测量信息或预配置的测量信息不可用，则向接入网设备发送请求消息。
情况3，终端设备确定未配置测量信息，且，终端设备确定预配置的所有测量信息都不满足终端设备的测量需求，则向接入网设备发送请求消息。
情况4，终端设备确定已配置的测量信息或激活的测量信息不满足终端设备的测量需求，且，终端设备确定预配置的所有测量信息都不满足终端设备的测量需求，则向接入网设备发送请求消息。
或者，终端设备在发送请求消息之前，可判断是否满足第一条件，在确定满足第一条件的基础上，可进一步判断是否满足第三条件，以判断是否需要发送请求消息。
或者，终端设备在发送请求消息之前，可同时判断是否满足第一条件和第三条件，以确定是否向接入网设备发送请求消息。
当终端设备既可以向接入网设备请求MG配置信息，又可以向接入网设备请求PPW配置信息时，终端设备可以按照预配置或配置的优先级顺序确定请求MG配置信息或PPW配置信息。具体参考示例2的相关内容，此处不再赘述。
示例5，触发条件为第一条件和第二条件。
例如，终端设备确定满足第一条件和第二条件，通过MAC CE信令发送请求消息，该请求消息用于请求激活预配置的测量信息。
终端设备在发送请求消息之前，可判断是否满足第一条件，在确定满足第一条件的基础上，可进一步判断是否满足第二条件，以确定是否向终端设备发送请求消息以及基于何种方式向终端设备发送请求消息。如果满足第二条件，即接入网设备允许终端设备通过MAC CE信令发送请求消息，则终端设备通过MAC CE信令发送请求消息，以尽量降低定位时延。相反，如果不满足第二条件，即接入网设备不允许终端设备通过MAC CE信令发送请求消息，则一种可能的实现方式是，终端设备可基于RRC信令发送请求消息。需要说明的是，满足第一条件，不满足第二条件，也可以认为是一种触发条件。即终端设备在 满足第一条件，不满足第二条件的触发下，基于RRC信令发送请求消息。
或者，终端设备在发送请求消息之前，终端设备可判断是否满足第二条件，在确定满足第二条件的基础上，可进一步判断是否满足第一条件，以确定通过MAC CE信令向接入网设备发送请求消息。
又或者，终端设备在发送请求消息之前，终端设备可同时判断是否满足第一条件和第二条件，以确定是否向接入网设备发送请求消息以及基于何种方式发送请求消息。
与示例1类似，当终端设备既可以向接入网设备请求激活MG的配置信息，又可以向接入网设备请求激活PPW的配置信息时，终端设备可以按照预配置或配置的优先级顺序确定请求激活MG的配置信息或请求激活PPW的配置信息。具体参考示例1的相关内容，此处不再赘述。
示例6，触发条件为第二条件和第三条件。
例如，终端设备确定满足第二条件和第三条件，通过MAC CE信令发送请求消息，该请求消息用于请求测量信息。
终端设备在发送请求消息之前，可判断是否满足第三条件，在确定满足第三条件的基础上，可进一步判断是否满足第二条件，以确定基于何种方式向终端设备发送请求消息。如果满足第二条件，即接入网设备允许终端设备通过MAC CE信令发送请求消息，则终端设备通过MAC CE信令发送请求消息，以尽量降低定位时延。相反，如果不满足第二条件，即接入网设备不允许终端设备通过MAC CE信令发送请求消息，则终端设备可基于RRC信令发送请求消息。需要说明的是，满足第三条件，不满足第二条件，也可以认为是一种触发条件。即终端设备在满足第三条件，不满足第二条件的触发下，基于RRC信令发送请求消息。
或者，终端设备在发送请求消息之前，可判断是否满足第二条件，在确定满足第二条件的基础上，可进一步判断是否满足第三条件，以确定通过MAC CE信令向接入网设备发送请求消息。
或者，终端设备在发送请求消息之前，可同时判断是否满足第一条件和第三条件，以确定是否向接入网设备发送请求消息以及基于何种方式发送请求消息。
与示例1类似，当终端设备既可以向接入网设备请求激活MG配置信息，又可以向接入网设备请求激活PPW配置信息时，终端设备可以按照预配置或配置的优先级顺序确定请求激活MG配置信息或请求激活PPW配置信息。具体参考示例1的相关内容，此处不再赘述。
示例7，触发条件为第一条件、第二条件和第三条件。
终端设备在确定满足第一条件、第二条件和第三条件，向接入网设备发送请求消息。该请求消息可用于请求激活接入网设备预配置测量信息。
终端设备在执行定位测量之前，可判断是否满足第三条件，确定满足第三条件，再判断是否满足第一条件。终端设备确定满足第一条件，再判断是否满足第二条件，以确定基于何种方式向终端设备发送请求消息。如果满足第二条件，即接入网设备允许终端设备通过MAC CE信令发送请求消息，则终端设备通过MAC CE信令发送请求消息，以尽量降低定位时延。相反，如果不满足第二条件，即接入网设备不允许终端设备通过MAC CE信令发送请求消息，则终端设备可基于RRC信令发送请求消息。
需要说明的是，满足第一条件和第三条件，不满足第二条件，也可以认为是一种触发 条件。即终端设备在满足第一条件和第三条件，不满足第二条件的触发下，基于RRC信令发送请求消息。且，本申请实施例对终端设备判断第一条件、第二条件和第三条件的先后顺序不作限制。
为了更好地理解本申请实施例提供的技术方案，下面介绍本申请实施例提供的通信方法的一个示例。请参考图5，为该方法的流程图。图5所示流程以需要执行定位测量的设备是终端设备为例。
S501、确定需要执行定位测量。
例如，终端设备接收到请求位置消息，例如LMF发送的LPP RequestLocationInformation消息，可确定需要执行定位测量。
S502、判断是否满足第三条件。
需要说明的是，触发条件可以不包括第三条件，因此，S502以虚线示意。
S503、确定满足第三条件，判断是否满足第一条件。
S504、确定不满足第三条件，则基于测量信息执行定位测量。
终端设备确定不满足第三条件，可基于MG的配置信息和/或PPW的配置信息执行定位测量。例如，如果接入网设备为终端设备配置了MG的配置信息和PPW的配置信息，终端设备可以按照预配置或配置的优先级顺序确定使用MG的配置信息或PPW的配置信息。具体可参考示例1的相关内容，这里不再赘述。
S505、确定满足第三条件，但不满足第一条件，发送请求消息，该请求消息用于请求测量信息。
S506、确定满足第三条件和第一条件，判断是否满足第二条件。
S507、确定满足第三条件、第一条件和第二条件，基于MAC CE信令发送请求消息，该请求消息用于请求激活预配置的测量信息。
S508、确定满足第三条件和第一条件，但不满足第二条件，基于RRC信令发送请求消息，该请求消息用于请求激活预配置的测量信息。
需要说明的是，图5以触发条件为第一条件和第二条件为例。因此，在图5中，S505至S507均以实线示意。应理解，终端设备也可以不执行S505至S507中的一个或多个步骤。
图5仅示例了第一条件、第二条件和第三条件的一种判断顺序，本申请实施例对第一条件、第二条件和第三条件的判断顺序不作限制，且对判断第一条件、第二条件和第三条件中的哪些条件不作限制。例如，终端设备可判断第一条件、第二条件和第三条件中的一个或多个条件。举例来说，终端设备可先判断是否满足第二条件(即S506)，再判断是否满足第一条件(即S503)。或者，如果终端设备不执行S502和S504，终端设备在执行S501之后，可判断是否满足第一条件(即S503)，若终端设备确定不满足第一条件，则执行S505。或者，如果终端设备不执行S502和S504，终端设备在执行S501之后，可判断是否满足第一条件，在确定满足第一条件执行S506-S508。又例如，如果终端设备不执行S502和S504，终端设备在执行S501之后，可判断是否满足第二条件(即S506)，进而执行S507或S508。
本申请实施例，终端设备确定满足触发条件，才向接入网设备请求激活预配置的测量信息，从而，可以避免在不满足触发条件向接入网设备请求激活预配置的测量信息，可以提高获取测量信息的成功率。且在MG的配置信息和PPW的配置信息同时存在时，优先使用MG的配置信息执行定位测量，可以降低终端设备的处理复杂度。在同时配置MG的 配置信息和PPW的配置信息时，优先请求PPW的配置信息；在同时预配置MG的配置信息和PPW的配置信息时，优先请求激活PPW的配置信息，从而降低对通信数据传输的影响。
以上以请求消息用于请求测量信息，或者请求消息用于请求激活预配置的测量信息为例。在可能的实现方式中，终端设备发送的请求消息也可能用于请求去激活已经配置或已经激活的测量信息。应理解，终端设备不使用“去激活”成功的测量信息。例如，终端设备不再需要已配置或已激活的测量信息，例如定位测量结束或部分已配置或已激活的测量信息已经足够满足测量需求，终端设备可发起去激活请求。这样可释放网络资源，提高资源利用率，并且降低终端的测量复杂度。
为此，本申请实施例也可以设置终端设备请求去激活已经配置或已经激活的测量信息的触发条件，终端设备确定满足触发条件，才发送去激活请求。从而，可以避免在不满足触发条件向接入网设备请求测量信息，可以提高去激活测量信息的成功率，并避免网络资源的浪费。
例如，终端设备确定满足第四条件和/或第五条件，发送请求消息。该请求消息用于请求去激活至少一套测量信息，例如，该请求消息用于请求去激活已配置的测量信息中的至少一套测量信息，或者，该请求消息用于请求去激活已经激活的测量信息中的至少一套测量信息。
第四条件为不再需要测量信息。也可以理解为，第四条件为不再需要已经配置的测量信息或已经激活的测量信息。例如，终端设备接收到停止或结束执行测量的消息，也认为不再需要测量信息。从这个角度来说，也可以将接收到停止或结束执行测量的消息作为第四条件。当终端设备确定满足第四条件，即终端设备不需要已配置或已激活的测量信息，从而，终端设备请求去激活某些测量信息，可释放网络资源，提高资源利用率，并且降低终端的测量复杂度。
第五条件为当前存在激活的测量信息。应理解，当前存在激活的测量信息，指的是，预配置了测量信息，且网络激活了预配置的一套或多套测量信息。例如通过MAC CE信令或RRC信令激活了预配置的一套或多套测量信息。或者，第五条件也可为测量信息被允许请求去激活。如果测量信息被允许请求去激活，那么也可以认为，存在已激活的测量信息或已配置的测量信息。可选地，第五条件为测量信息被允许通过MAC CE信令请求去激活。也可以理解为，第五条件为允许终端设备通过MAC CE信令请求去激活已经配置或已经激活成功的测量信息，或者，第五条件为终端设备通过MAC CE信令请求去激活测量。当终端设备确定第五条件，终端设备可基于MAC CE信令发送去激活请求，以降低定位时延；终端设备确定不满足第五条件，终端设备可基于RRC信令发送去激活请求。可选地，第五条件为测量信息被允许通过RRC信令请求去激活。也可以理解为，第五条件为允许终端设备通过RRC信令请求去激活已经配置或已经激活成功的测量信息，或者，第五条件为终端设备通过RRC信令请求去激活测量。可选地，当激活的测量信息由MAC CE信令激活，相应地，该测量信息被允许通过MAC CE信令去激活。可选地，当激活的测量信息由RRC信令激活，相应地，该测量信息被允许通过RRC信令去激活。
终端设备发起请求消息之前，可以判断是否满足第四条件。如果满足第四条件发送请求消息，则终端设备可发送请求消息。或者，终端设备确定满足第四条件之后，可进一步判断是否满足第五条件，以确定基于何种方式向终端设备发送请求消息。如果满足第五条 件，则终端设备可通过MAC CE信令发送请求消息，以尽量降低定位时延。相反，如果不满足第五条件，则终端设备可基于RRC信令发送请求消息。
或者，终端设备发起请求消息之前，可以判断是否满足第五条件，在确定满足第五条件之后，可进一步判断是否满足第四条件，以确定是否通过MAC CE信令发送请求消息。
或者，终端设备在发送请求消息之前，可同时判断是否满足第四条件和第五条件，以确定是否发送请求消息以及基于何种方式发送请求消息。
由于接入网设备确定测量配置信息和发送测量信息需要一定的时间，因此，终端设备在发送请求消息之后的一段时间内，可先等待网络的响应消息，在等待期间不用再次发送请求消息，避免终端设备频繁地发起请求，以尽量降低终端设备的能耗。
在可能的实现方式中，终端设备在确定需要发送请求消息时，可以启动(或重新启动)第一定时器。或者，终端设备确定需要发送请求消息之后，可以启动(或重新启动)第一定时器。为方便描述，下文以终端设备启动第一定时器。如无特殊说明，终端设备启动第一定时器，可替换为，终端设备重新启动第一定时器。例如，终端设备在执行S503或S506之后，启动第一定时器。又或者，终端设备在发送请求消息时，可以启动第一定时器。或者，终端设备在发送请求消息之后，可以启动第一定时器。例如，终端设备在执行S505或S507或S508之后，启动第一定时器。这样在终端设备发送请求消息后的一段时长内(例如第一定时器工作期间)，终端设备无需再次发送请求消息，从而可避免频繁地发送请求消息，降低终端设备的能耗。
第一定时器的参数可以是预定义的，或者，第一定时器的参数可以是网络预配置的，或者，第一定时器的参数也可以是网络配置的。例如，第一定时器的参数可以是接入网设备或定位管理设备配置或预配置的。接入网设备可基于RRC信令配置第一定时器的参数，定位管理设备可基于LPP消息配置第一定时器的参数。第一定时器的参数可包括：第一定时时长，请求消息的最大发送次数，或测量信息的最多请求套数等一项或多项。第一定时时长，可以理解为，第一定时器从启动到到期之间的时长。请求消息的最大发送次数，可以理解为，允许终端设备发送请求消息的最大次数。类似的，测量信息的最多请求套数，可以理解为，允许终端设备请求测量信息的最多套数。
终端设备在不同时刻发送的请求消息所请求的测量信息可以相同。例如，终端设备在第一时刻发送第一请求消息，该第一请求消息可用于请求第一测量信息，终端设备在第二时刻发送第二请求消息，该第二请求消息可用于请求第二测量信息，其中，第一测量信息和第二测量信息可以相同。也就说，请求消息的最大发送次数和测量信息的最多请求套数可以不同。当然，终端设备在不同时刻发送的请求消息所请求的测量信息也可以不相同，例如，终端设备在第一时刻发送第一请求消息，该第一请求消息可用于请求第一测量信息，终端设备在第二时刻发送第二请求消息，该第二请求消息可用于请求第二测量信息，其中，第一测量信息和第二测量信息不同。也可以认为，终端设备在后一时刻所请求的测量信息，也可以是先前已经请求配置过的或者先前请求激活过的，也可以是先前未请求配置过或未请求激活过的。
终端设备确定需要发送请求消息时或确定需要发送请求消息之后，可以累计终端设备发送请求消息的次数。或者，终端设备确定需要发送请求消息时或确定需要发送请求消息之后，也可以累计终端设备请求的测量信息的套数。或者，终端设备确定需要发送请求消息时或确定需要发送请求消息之后，既可以累计终端设备发送请求消息的次数，又可以累 计终端设备请求的测量信息的套数。当累计终端设备发送请求消息的次数达到所述请求消息的最大发送次数，第一定时器结束。或者累计终端设备请求的测量信息的套数达到所述测量信息的最多请求套数，第一定时器结束。当累计终端设备发送请求消息的次数达到所述请求消息的最大发送次数，并且累计终端设备请求的测量信息的套数达到所述测量信息的最多请求套数，第一定时器结束。当第一定时器的持续时间达到第一定时时长(也可以认为第一定时器超时)，第一定时器停止。终端设备启动第一定时器之后，终端设备接收到请求消息的响应消息，例如接入网设备重新配置测量信息的消息，或者接入网设备激活预配置的测量信息的消息，就能获取测量信息，从而无需继续等待定时器，可结束第一定时器。因此，在终端设备接收到响应消息时或在接收到响应消息之后，第一定时器结束。应理解，第一定时器从启动到结束之间的最长时长不超过第一定时器从启动到到期之间的最长时长，即第一定时时长。
也可以认为，累计终端设备发送请求消息的次数达到所述请求消息的最大发送次数是第一定时器的一种结束条件，例如称为第一结束条件。类似的，累计终端设备请求的测量信息的套数达到所述测量信息的最多请求套数称为第二结束条件。累计终端设备发送请求消息的次数达到所述请求消息的最大发送次数，以及累计终端设备请求的测量信息的套数达到所述测量信息的最多请求套数称为第三结束条件。第一定时器超时，称为第四结束条件。终端设备接收到响应消息时或在接收到响应消息之后称为第五结束条件。
请参见图6，为本申请实施例提供的第一定时器的工作流程示意图。应理解，图6以第一定时器的结束条件包括第一结束条件和第二结束条件为例。图6涉及到第一定时器的两个变量，即第一变量(ActiMG_TransCOUNTER)和第二变量(ActiMG_ReqCOUNTER)，其中，第一变量用于指示终端设备发送请求消息的次数，第二变量用于指示终端设备请求的测量信息的套数。终端设备发送一次请求消息，第一变量加1；终端设备请求的测量信息与之前已经请求的测量信息不同，第二变量加1。第一变量和第二变量的初始值为0。
S601、发送请求消息。可选地，第一变量加1。
S602、判断请求消息是否重复请求测量信息。也就是，判断请求消息请求的测量信息是否与之前请求的测量信息相同。
S603、确定请求消息不是重复请求测量信息，第二变量加1。需要说明的是，S603之后，继续执行S604，即判断是否满足第一结束条件和/或第二结束条件。
S604、确定请求消息重复请求测量信息，判断是否满足第一结束条件和/或第二结束条件。
S605、确定满足第一结束条件和/或第二结束条件，停止运行。
如果不满足第一结束条件和/或第二结束条件，继续执行S601。
相应的，请参见图7，为本申请实施例提供的使用第一定时器的流程图。图7以第一定时器的结束条件不包括第四结束条件为例。
S701、发送请求消息。
以终端设备发送请求消息为例，S701可以是图5中的S507。
S702、启动第一定时器。
应理解，第一定时器被启动之后，第一定时器可执行图6所示的流程。
S703、判断第一定时器是否结束。
以终端设备需要发送请求消息为例，在第一定时器超时之前，如果终端设备接收到请 求消息的响应消息，终端设备可确定第一定时器结束。第一定时器执行图6所示的流程，如果第一定时器确定满足第一结束条件和/或第二结束条件，可通知终端设备，第一定时器结束。
S704、确定第一定时器未结束，继续等待。
S705、确定第一定时器结束，且未接收到请求消息的响应消息，通过RRC信令发送请求消息。应理解，图7以第一定时器的结束条件不包括第四结束条件为例。如果第一定时器的结束条件包括第四结束条件，那么第一定时器停止之后，继续执行S701。
在第一定时器结束之后，终端设备还没有接收到请求消息的响应消息，可以认为，接入网设备没有激活终端设备请求激活的预配置测量信息。这种情况下，终端设备可通过RRC信令向接入网设备请求测量信息。例如，终端设备可判断接入网设备是否激活了测量信息，或者判断接入网设备配置或激活的测量信息是否满足测量需求。终端设备确定接入网设备没有激活测量信息，或者终端设备确定接入网设备激活或配置的测量信息不满足测量需求，可向接入网设备再次发送请求消息。
如果在预设时长内没有接收到响应消息，可以认为，终端设备没有获取到测量信息，也就是终端设备获取测量信息失败。此时，终端设备可发送失败消息，该失败消息指示基于获取测量信息失败。失败消息指示基于获取测量信息失败，也可以理解为，该失败消息指示定位测量失败，或者，指示无法提供测量结果或者定位结果。这样接入网设备可以明确终端设备定位失败，从而后续可以为终端设备重新配置测量信息，以尽量提高终端设备获取测量信息的成功率。可选地，该失败消息可指示定位测量失败的原因，为网络重新配置测量信息提供参考。
其中，预设时长可以是预配置的，也可以是接入网设备配置的，或者该预设时长也可以通过定时器的方式实现，对此，本申请实施例不作限制。
由于接入网设备确定测量信息和发送测量信息需要一定的时间，终端设备按照例如图5所示的流程判断是否需要发送请求消息的过程中，或者终端设备发送请求消息之后的一段时间内，接入网设备可能已经向终端设备配置了测量信息，或者发送了激活预配置的测量信息的指示。这种情况下，终端设备如果还是基于触发条件判断是否向接入网设备发送请求消息，会造成发送不必要的请求消息，或者提前发送请求消息，引入定时时延。
为此，终端设备在发送请求消息之前，可以启动第二定时器。也可以理解为，通过第二定时器给接入网设备预留一定的时间配置测量信息或者激活预配置的测量信息。这样终端设备在第二定时器超时之前，如果网络配置了测量信息或者激活了预配置的测量信息，终端设备无需发送请求消息，从而降低定位时延。可以理解的是，终端设备在接收到响应消息时，或终端设备在接收到请求消息的响应消息之后，停止第二定时器。
第二定时器的参数可以是预定义的，也可以是网络预配置或配置的。例如，例如，第二定时器的参数可以是接入网设备或定位管理设备预配置或配置的。接入网设备可基于RRC信令配置第二定时器的参数，定位管理设备可基于LPP消息配置第二定时器的参数。例如，第二定时器的参数包括第二定时器的第二定时时长，也就是，第二定时器从启动到到期之间的时长。
可选地，终端设备在执行S501之后，可以启动第二定时器。或者，终端设备在执行S507或S508之前的任意时刻都可以启动第二定时器。例如，终端设备可以在执行S502或S503或S506之前，启动第二定时器。对于终端设备而言，在发送请求消息之前，启动 第二定时器。如果第二定时器没有超时，那么终端设备继续等待。如果第二定时器超时，那么终端设备发送请求消息。以图5为例，终端设备在执行S501之后，在执行S502之前，启动第二定时器，当第二定时器超时，终端设备可执行S502，以及S502之后的步骤。如果终端设备在执行S503之前，启动第二定时器，当第二定时器超时，终端设备可执行S503，以及S503之后的步骤。如果终端设备在执行S506之前，启动第二定时器，当第二定时器超时，终端设备可执行S506，以及S506之后的步骤。
需要说明的是，终端设备启动第一定时器的方案，与前述终端设备确定满足触发条件发送请求消息的方案，可以是独立的。也就是说，在可能的实现方式中，终端设备无需判断是否满足触发条件，只要终端设备发送请求消息，就启动第一定时器。在可能的实现方式中，终端设备只判断是否满足触发条件，无需启动第一定时器。
类似的，终端设备启动第二定时器的方案，与前述终端设备确定满足触发条件发送请求消息的方案，可以是独立的。也就是说，在可能的实现方式中，终端设备无需判断是否满足触发条件，只要终端设备确定发送请求消息，就启动第二定时器。终端设备发送请求消息时或发送请求消息之后，启动第一定时器的方案，与终端设备发送请求消息之前，启动第二定时器的方案，也可以是独立的。
当然，终端设备启动第一定时器的方案与终端设备启动第二定时器的方案，可以互相结合。需要说明的是，本申请实施例以终端设备启动第一定时器、第二定时器为例，本申请实施例对启动第一定时器和第二定时器的执行主体不作限制。本申请实施例以终端设备执行定位测量为例，终端设备向接入网设备发送请求消息为例。本申请实施例对执行定位测量的设备不作限制，且对该设备向谁发送请求消息也不作限制。例如，可以向LMF发送请求消息。
