Description

一种定位方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种定位方法及装置。
背景技术
目前通信发展中，对定位业务的稳定性提出了较高的要求，如网络侧要在规定时间内向外部应用功能网元(application function，AF)或客户端(client)返回用户设备(user equipment，UE)定位结果、无论发生什么情况网络侧一定要向外部AF或client返回定位结果等等。
目前，定位业务的流程中，接入和移动性管理功能(access and mobility management function，AMF)在接收到位置请求(location request)后，根据location request里面的内容以及现有选择机制为location request选择一个合适的定位管理功能(location management function，LMF)，由该LMF对UE进行定位。但是LMF上资源有限，因此当进行更精准的定位业务时，可能因为某些原因，如LMF出现故障关闭(shut down)了，或者LMF同时使用多种定位算法导致增加额外的时间消耗从而增加整个定位业务的时延等，导致定位业务的稳定性得不到保证。

需要说明的是，图1所示的通信系统并不构成本申请实施例能够适用的通信系统的限定。图1所示的通信系统架构为5G系统架构，可选的，本申请实施例的方法还适用于未来的各种通信系统，例如6G或者其他通信网络等。
目前通信发展中，对定位业务的稳定性提出了较高的要求，如网络侧要在规定时间内向外部应用功能网元(application function，AF)或客户端(client)返回用户设备(user equipment，UE)定位结果、无论发生什么情况网络侧一定要向外部AF或client返回定位结果等等。
目前，定位业务的流程为：外部AF通过NEF或者GMLC向核心网发起位置请求(location request)，请求定位特定UE。GMLC或NEF收到location request之后，将location request发给AMF，AMF会根据location request里面的内容以及现有选择机制为location request选择一个合适的LMF，LMF是定位业务真正的执行主体，LMF收到location request之后，会选择合适的定位算法(positioning method)，positioning method代表一种定位计算方式或者算法，选定positioning method之后，LMF将让UE收集特定的测量数据(measurement data)，如UE和周围基站的信号强度等等。UE上报measurement data之后，LMF根据measurement data,再结合对应的positioning method算法计算出UE location information,最后将UE location information反馈给外部AF或client。
然而，现有流程中，核心网的AMF只会为一个location request选择一个LMF，这个选择是基于AMF选择的一个最优的LMF，但是每个LMF上同时会处理多个location requests，而且每个LMF上资源有限，所以有时候会导致某些location request处理不及时， 或者因其他原因，比如选择的这个LMF出现故障shut down了，会导致某个location request根本没有被成功处理，从而造成定位业务中断，进而外部AF或client收不到UE location响应，这样就会造成定位业务稳定性(响应确定性)得不到保证。
其次，现有流程中，被选择的LMF会根据location request选择合适的定位算法(positioning methods)，例如观测到达时间差(observed time difference of arrival，OTDOA)、辅助全球导航卫星系统(assisted-global navigation satellite system，A-GNSS)、蓝牙(Bluetooth)、无线保真(wireless-fidelity，WiFi)等，根据外部AF或client需求，被选择的LMF可能同时使用多种positioning methods。但是多一种positioning method就代表了额外的计算量，即代表了额外时间消耗，会增加整个业务的延迟(latency),这样就会降低业务稳定性(响应时间稳定性)。
基于此，本申请实施例提供一种定位方法及装置。其中，方法和装置是基于同一技术构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
应理解，本申请实施例中“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和b，a和c，b和c，或a、b和c，其中a、b、c可以是单个，也可以是多个。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。

实施例一：
参阅图2所示，本申请实施例针对终端提供一种定位方法，该方法包括：
S201，AMF接收用于请求对终端设备进行定位的第一定位请求。
一种实现方式中，步骤S201可以通过如下方式实现：AF或者定位服务(location service，LCS)客户端(LCS Client)向GMLC发送用于请求对终端设备进行定位的第三定位请求，GMLC向AMF发送第一定位请求。
另一种实现方式中，步骤S202还可以通过如下方式实现：该终端设备向AMF发送第一定位请求。
示例性的，第一定位请求可以携带指示信息，该指示信息用于指示第一定位请求请求高可靠定位业务。AMF可以在第一定位请求中携带指示信息时可以执行本申请实施例一提供的定位方法。
指示信息可以命名为high reliability indicator，当然指示信息也可以命名为其他，如X，可以理解的，只要X可以实现本申请实施例一中指示信息的功能，可以将X理解为本申请实施例一中的指示信息。为了描述上的方面，下面统一将指示信息称为high reliability indicator 1。
在一些实施例中，若第一定位请求由终端设备向AMF发送的，AMF在接收到携带high reliability indicator 1的第一定位请求后可以确定该终端设备是否已订阅高可靠定位(high  reliability LCS)业务。若是，则可以执行步骤S202。若否，AMF可以选择一个LMF，并向该LMF发送第二定位请求。示例性的，AMF可以通过访问UDM确认该终端设备是否订阅了high reliability LCS业务。
在另一些实施例中，若第一定位请求由GMLC在接收到AF或者LCS Client发送的第三定位请求后向AMF发送的，第三定位请求也可以携带high reliability indicator 1。GMLC可以在接收到携带high reliability indicator 1的第三定位请求后可以确定该AF或者LCS Client是否已订阅高可靠定位业务。若是，则可以向AMF发送携带high reliability indicator 1的第一定位请求。若否，则可以向AMF发送不携带high reliability indicator 1的第一定位请求。示例性的，GMLC可以通过访问UDM确认该AF或者LCS Client是否订阅了high reliability LCS业务。
一种示例性说明中，第一定位请求可以通过一个信元来携带high reliability indicator 1。或者，第一定位请求也可以通过一个比特位来指示high reliability indicator 1，例如，当该比特位取值为1时表示第一定位请求用于请求高可靠定位业务，当该比特位取值为0时表示第一定位请求用于请求非高可靠定位业务。又例如，当该比特位取值为0时表示第一定位请求用于请求高可靠定位业务，当该比特位取值为1时表示第一定位请求用于请求非高可靠定位业务。

S206，AMF基于多个LMF反馈的位置信息确定定位结果。
一种可能的实施方式中，AMF可以在多个LMF反馈的位置信息中选择一个位置信息作为定位结果。例如，定位结果可以为多个LMF反馈的位置信息中最早反馈的位置信息。又如，定位结果也可以为多个LMF反馈的位置信息中精确度最高的位置信息。
另一种可能的实施方式中，AMF可以在多个LMF反馈的位置信息中选择至少一个位置信息，然后将该至少一个位置信息按照预设算法计算定位结果。例如，AMF可以选择最先接收的N个位置信息，然后将该N个位置信息按照预设算法计算定位结果。又例如，AMF可以选择单位时间内最先接收的N个位置信息，然后将该N个位置信息按照预设算法计算定位结果。又例如，AMF可以选择精度从高到低排序的前N个位置信息，然后将该N个位置信息按照预设算法计算定位结果。又例如，AMF可以选择单位时间内精度从高到低排序的前N个位置信息，然后将该N个位置信息按照预设算法计算定位结果。其中，N为小于或等于多个LMF中LMF数量的正整数，例如，以步骤S306确定了5个LMF为 例，N可以为小于或等于5的正整数。
又一种可能的实施方式中，AMF可以将多个LMF反馈的位置信息按照预设算法计算定位结果。
在一些实施例中，AMF还可以向GMLC发送该定位结果。GMLC可以根据该定位结果进行特殊业务计费，记录收费信息(record charging information)，如记录返回的次数等等。
若第一定位请求由GMLC在接收到AF或者LCS Client发送的第三定位请求后向AMF发送的，GMLC在对该定位结果进行特殊业务计费后，还可以向AF或者LCS Client发送响应信息。
若第一定位请求由终端设备向AMF发送的，GMLC在对该定位结果进行特殊业务计费后，还可以向AMF发送响应信息。AMF可以向终端设备反馈定位结果。

实施例二：
参阅图5所示，本申请实施例针对终端提供另一种定位方法，该方法包括：
S501，AMF向第一LMF发送用于请求对终端设备进行定位的第一定位请求。相应的，第一LMF接收AMF发送的第一定位请求。
一种可能的实现方式中，在步骤S501之前，AMF可以接收用于请求对终端设备进行定位的第三定位请求，AMF可以根据该第三定位请求选择第一LMF。
