Description

用于定位的通信方法以及通信装置
本申请要求于2021年5月21日提交中国国家知识产权局，申请号为202110559090.8，发明名称为“用于定位的通信方法以及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种通信方法以及通信装置。
背景技术
定位功能是5G新空口(new radio，NR)的一项重要功能。目前，位置管理功能(location management function，LMF)设备会获取终端设备所在的小区的位置信息进行定位。如何提升定位性能，是个值得考虑的问题。
发明内容
本申请实施例提供了一种通信方法和通信装置，以期提升定位性能。
本申请实施例第一方面提供一种通信方法，方法包括：
定位设备向接入网设备发送请求。该请求用于请求接入网设备的小区类型的信息。然后，定位设备接收来自接入网设备的小区类型的信息。小区类型包括：室内小区、或室外小区。或者，小区类型包括以下任一种：宏站小区、微小区、或灯站小区。
由上述方案可知，定位设备从接入网设备获取小区类型的信息。这样定位设备可以参考小区类型的信息为终端设备选择更为适用的定位方法。从而提升定位精度，提高定位性能。例如，定位方法包括基于无线接入技术的定位方法、全球导航卫星系统(global navigation satellite system，GNSS)定位方法等。接入网设备的小区处于室内，也可能处于室外。接入网设备通过室内小区或室外小区告知定位设备接入网设备的每个小区的类型。宏站通常部署在室外，小站、微站和灯站通常部署在室内。因此接入网设备通过宏站小区、微小区、或灯站小区以间接告知定位设备该小区属于室外小区还是属于室外小区。
例如，室内的GNSS信号非常弱，因此GNSS定位方法对处于室内的终端设备并不能适用。若定位设备确定终端设备处于室内，定位设备可以为终端设备选择基于无线接入技术的定位方法。例如，GNSS定位方法更适用于室外场景。终端设备处于室外，基站的间隔距离比较大，而GNSS信号比较强。那么定位设备可以为终端设备选择GNSS定位方法。
一种可能的实现方式中，定位设备向接入网设备发送请求，包括：定位设备通过传输接收点(transmission reception point，TRP)信息请求消息向接入网设备发送请求。定位设备接收来自接入网设备的小区类型的信息，包括：定位设备通过TRP信息响应消息接收来自接入网设备的小区类型的信息。
在该可能的实现方式中，定位设备通过TRP信息请求来请求和获取接入网设备的小区类型的信息。这样无需定义新的消息，节省消息资源，提升了方案的实用性。并且，TRP信息可以包括小区的信息，这样有利于接入网设备解析定位设备的请求。并且定位设备可 以结合TRP信息确定小区类型的信息是哪个小区的类型的信息。定位设备无需通过其他指示信令或指示字段指示具体请求哪个小区或哪些小区的类型的信息。接入网设备也无需通过其他指示指令或指示字段指示具体提供的哪个小区或哪些小区的类型的信息。从而节省信令开销或比特开销。
另一种可能的实现方式中，TRP信息请求消息包括TRP信息类型项。请求用于请求小区类型的信息，包括：通过TRP信息类型项请求小区类型的信息。
在该可能的实现方式中，TRP信息类型项用于列举定位设备请求的TRP信息。因此，定位设备可以通过TRP信息类型项向接入网设备请求小区类型的信息。这样无需重新定义新的信元，TRP信息请求消息的信元较为简洁。定位设备通过TRP信息请求消息中的TRP信息类型项请求小区类型的信息，即提供了一种具体的请求方式。并且，TRP信息类型项中列举的是定位设备请求的TRP信息，TRP信息包括小区的信息。定位设备通过TRP信息类型项向接入网设备请求小区类型的信息。定位设备无需通过其他指示字段或指示指令指示具体请求的是哪个小区或哪些小区的类型的信息。从而节省信令开销或比特开销。
另一种可能的实现方式中，TRP信息响应消息包括TRP信息，接入网设备的小区类型的信息承载于TRP信息。
在该可能的实现方式中，接入网设备通过TRP信息响应消息中的TRP信息向定位设备发送小区类型的信息。这样无需定义新的信元，TRP信息响应消息的信元较为简洁。接入网设备通过TRP信息响应消息中的TRP信息携带小区类型的信息，即提供了一种具体的携带方式。并且，TRP信息中列举的是接入网设备向定位设备提供的TRP信息，TRP信息包括小区的信息。因此，小区类型的信息放置在TRP信息中。这样有利于定位设备解析小区类型的信息。接入网设备无需通过其他指示字段或指示指令指示具体提供的是哪个小区或哪些小区的类型的信息。从而节省信令开销或比特开销。
另一种可能的实现方式中，在小区类型包括以下任一种：宏站小区、微小区、或灯站小区的情况下，请求还用于请求接入网设备的小区的室内或室外信息。
在该可能的实现方式中，定位设备可以进一步向接入网设备请求小区的室内或室外信息。这样定位设备结合小区的室内或室外信息和小区类型的信息可以更准确地确定终端设备的室内或室外情况，从而为终端设备选择更为适用的定位方法。提高定位精度，提升定位性能。

请参阅图1，图1为本申请实施例通信系统的一个示意图。通信系统包括接入网设备 和核心网设备。接入网设备部署在无线接入网中，接入网设备为终端设备提供无线通信功能。核心网设备负责终端设备的接入网络的接入控制、注册管理、业务管理、移动性管理等。
接入网设备可以包括下一代节点B(next Generation Node B，gNB)102。终端设备101与gNB102连接。上述图1仅仅示出了该通信系统包括gNB102的示例。而实际应用中，该通信系统还可以包括更多接入网设备，或者，该通信系统只包括一个接入网设备，具体本申请不做限定。接入网设备与核心网设备之间可以互相通信。终端设备可以与接入网设备之间互相通信。接入网设备还可以通过接入网设备与核心网设备互相通信。
核心网设备可以包括移动性管理设备103和定位设备104。移动性管理设备103用于对终端设备101的移动性进行管理。定位设备用于对终端设备101的位置进行定位处理和管理。

目前，定位设备从AMF设备接收定位请求。定位请求包括终端设备的标识。定位设备获取终端设备的能力信息。然后，定位设备根据定位请求包括的信息和终端设备的能力信息为终端设备选择相应的定位方法。例如，基于无线接入技术的定位方法、GNSS定位方法。定位设备通过选择的定位方法对终端设备进行定位，从而实现对终端设备的定位。
下面结合具体实施例介绍本申请的技术方案。
图2为本申请实施例通信方法的一个实施例示意图。请参阅图2，通信方法包括：
201、定位设备向接入网设备发送请求，请求用于请求接入网设备的小区类型(cell type)的信息。相应的，接入网设备接收来自定位设备的请求。
下面介绍接入网设备的小区类型的两种可能的实现方式。对于其他实现方式本申请仍适用，下述两种可能的实现方式并不属于对本申请的限定。
实现方式1：接入网设备的小区类型包括：室内小区或室外小区。
具体的，接入网设备的小区可能处于室内，也可能处于室外。接入网设备可以通过室内小区或室外小区告知定位设备接入网设备的小区类型。
实现方式2：接入网设备的小区类型包括以下任一种：宏站小区(macro cell)、微小区(micro cell)、或灯站小区(lampsite cell)。
宏站的发射功率较大，信号覆盖范围较大。宏站一般部署于室外。因此,宏站小区通常为室外小区。
相对宏站来说，小站或微站的发射功率较小，信号覆盖范围较小。小站通常部署于楼宇或密集区域。小站或微站的小区可以称为微小区。因此，微小区通常为室内小区。
灯站通常部署于室内，主要用于室内信号覆盖。因此，灯站小区通常为室内小区。
由此可知，宏站通常部署在室外，小站、微站和灯站通常部署在室内。接入网设备可以通过实现方式2告知定位设备接入网设备的每个小区的类型。例如，接入网设备向定位设备上报小区1为宏站小区。由于宏站通常部署在室外，因此定位设备可以确定小区1为室外小区。
再例如，接入网设备向定位设备上报小区2为灯站小区。由于灯站通常部署在室内，因此定位设备可以确定小区2为室内小区。
可选的，在实现方式2中，该请求还可以用于请求接入网设备的小区的室内或室外信息。
其中，接入网设备的小区的室内或室外信息包括：小区处于室内的信息，或者，小区处于室外的信息。
例如，接入网设备的小区包括小区1和小区2。小区1为室外小区，小区2为室内小区。因此，接入网设备的小区的室内或室外信息包括：小区1处于室内的信息和小区2处于室外的信息。
202、接入网设备向定位设备发送小区类型的信息。相应的，定位设备接收来自接入网 设备的小区类型的信息。
在请求还用于请求小区的室内或室外信息的情况下，上述步骤202中接入网设备还向定位设备发送小区的室内或室外信息。相应的，定位设备接收来自接入网设备的小区的室内或室外信息。
那么，接入网设备可以通过TRP信息响应消息或其他消息向定位设备发送小区的类型和小区的室内或室外信息，具体本申请不做限定。
可选的，上述图2所示的实施例还可以包括步骤203和步骤204。
203、定位设备根据小区类型的信息为终端设备选择相应的定位方法。
例如，终端设备所在的小区是该接入网设备的小区。定位设备可以根据接入网设备的小区类型的信息确定终端设备所在的小区的类型。然后，定位设备根据终端设备所在的小区的类型为终端设备选择对应的定位方法。
在一些实施方式中，定位方法包括以下至少一种：基于无线接入技术的定位方法、GNSS定位方法、或其他定位方法。
可选的，基于无线接入技术的定位方法包括以下至少一种：上行定位方法、下行定位方法、或单站定位方法。
上行定位方法包括上行到达时间差(uplink time difference of arrival，UL-TDOA)定位方法、和/或上行到达角(uplink time angle of arrival，UL-AOA)定位方法。
UL-TDOA定位方法包括：接入网设备测量终端设备发送的上行信号，得到多个上行相对到达时间(relative time of arrival，RTOA)。定位设备基于接入网设备上报的该多个RTOA确定终端设备的位置。
UL-AOA定位方法包括：接入网设备测量来自终端设备的上行信号，得到多个AOA。定位设备基于接入网设备上报的多个AOA确定终端设备的位置。
下行定位方法包括下行到达时间差(downlink time difference of arrival，DL-TDOA)定位方法，和/或下行离开角(downlink angle of departure，DL-AOD)定位方法。
DL-TDOA定位方法包括：终端设备测量多个接入网设备的下行参考信号，得到多个TDOA。终端设备根据多个TDOA确定终端设备的位置。或者，定位设备根据终端设备上报的多个TDOA确定终端设备的位置。
DL-AOD定位方法包括：终端设备测量多个接入网设备的下行参考信号，得到多个参考信号接收功率(reference signal receiving power，RSRP)。终端设备根据多个RSRP和多个接入网设备的配置信息确定终端设备的位置。或者，定位设备根据多个RSRP和多个接入网设备的配置信息确定终端设备的位置。
单站定位方法包括新空口增强的小区标识(new radio enhanced cell identification，NR E-CID)定位方法。
NR E-CID定位方法包括：接入网设备根据终端设备所在的小区的信息和/或终端设备对该小区的参考信号的测量量确定终端设备的位置。
GNSS定位方法包括基于终端设备测量GNSS信号得到的测量结果确定终端设备的位置。
例如，终端设备所在的小区为接入网设备的小区1。小区1为室外小区。由于基站的 间隔距离比较大，而GNSS信号较强。GNSS定位方法的定位精度优于基于无线接入技术的定位方法的定位精度，且GNSS定位时延更短。定位设备可以为终端设备选择GNSS定位方法。
例如，终端设备所在的小区为接入网设备的小区2。小区2为室内小区。由于室内的GNSS信号非常弱，因此GNSS定位方法对处于室内的终端设备并不能适用。因此，定位设备可以为终端设备选择基于无线接入技术的定位方法。而基于无线接入技术的定位方法包括的定位方法有多种，定位设备可以结合终端设备的能力信息等确定具体的定位方法。
定位设备接收来自接入网设备的小区类型的信息。这样，定位设备可以参考小区类型的信息为终端设备选择更为适用的定位方法，从而保证终端设备的定位精度。进一步地，终端设备在定位过程中可能会移动。例如，终端设备从室内移动到室外，或者从室外移动到室内，或者从GNSS信号弱的地方移动到GNSS信号强的地方。定位设备可以参考小区类型的信息及时为终端设备选择更为适用的定位方法。从而提高定位精度，提升定位性能。
例如，如果终端设备从室内移动到室外，定位设备在终端设备移动之前为终端设备选择的是基于无线接入技术的定位方法。定位设备可以参考小区类型的信息确定终端设备所在的小区为室外小区。由于室外的GNSS信号比较强，那么定位设备可以重新为终端设备选择GNSS定位方法。从而保证终端设备的高精度定位。
如果终端设备从室外移动到室内，定位设备在终端设备移动之前为终端设备选择的是GNSS定位方法。定位设备可以参考小区类型的信息确定终端设备所在的小区为室内小区。由于室内的GNSS信号非常弱，因此定位设备可以重新为终端设备选择基于无线接入技术的定位方法。从而保证终端设备的高精度定位。
由此可知，终端设备处于室内所适用的定位方法与终端设备处于室外所适用的定位方法不同。因此，定位设备可以获取小区类型的信息。这样，定位设备可以参考小区类型的信息为终端设备选择更为适用的定位方法。
在获取到小区类型的信息和小区的室内或室外信息的情况下，定位设备可以参考这些信息，并为终端设备选择相应的定位方法。
204、定位设备通过选择的定位方法对终端设备进行定位。
例如，定位设备参考小区类型的信息为终端设备选择GNSS定位方法。定位设备可以通过GNSS定位方法对终端设备进行定位。
例如，定位设备参考小区类型的信息为终端设备选择基于无线接入技术的定位方法。定位设备可以通过基于无线接入技术的定位方法对终端设备进行定位。
本申请实施例中，定位设备向接入网设备发送请求。该请求用于请求接入网设备的小区类型的信息。然后，定位设备接收来自接入网设备的小区类型的信息。由上述方案可知，定位设备从接入网设备获取小区类型的信息。这样定位设备可以参考小区类型的信息为终端设备选择更为适用的定位方法。从而提升定位精度，提高定位性能。例如，室内的GNSS信号非常弱，因此GNSS定位方法对处于室内的终端设备并不能适用。所以当定位设备确定终端设备处于室内时，定位设备可以优先为终端设备选择基于无线接入技术的定位方法。

GNSS测量量的可用度可以通过多种实现方式表示，下面介绍两种可能的实现方式。
方式1、GNSS测量量的可用度通过数值表示。若该数值较大，表示GNSS测量量的可用度较高，GNSS测量量的准确性较高。若数值较小，表示GNSS测量量的可用度较低，GNSS测量量的准确性较低。
方式2、GNSS测量量的可用度通过比值表示。若比值较大，表示GNSS测量量的可用度较高，GNSS测量量的准确性较高。若比值较小，表示GNSS测量量的可用度较低，GNSS测量量的准确性较低。
另一种可能的实现方式中，GNSS测量量用于表示终端设备测量得到的GNSS测量量的是否可用。例如，GNSS测量量不可用，那么代表该GNSS测量量的准确性较低。GNSS测量量可用，那么代表该GNSS测量量的准确性较高。例如，GNSS测量量的可用度通过“1”或“0”表示。当GNSS测量的可用度通过“1”表示时，表示该GNSS测量量可用，GNSS测量量的准确性较高。当GNSS测量量的可用度通过“0”表示时，表示GNSS测量量不可用，GNSS测量量的准确性较低。
一种可能的实现方式中，GNSS定位位置的可信度表示终端设备确定得到的GNSS定位位置的可信程度。例如，当GNSS定位位置的可信度越高，代表GNSS定位位置的准确性越高。当GNSS定位位置的可信度越低，代表GNSS定位位置的准确性越低。

可见卫星数量是指从终端设备的角度，终端设备能够接收到的卫星信号对应的卫星数量。通常终端设备的可见卫星数量至少为4个，以实现对终端设备的精准定位。例如，终端设备能够接收到四个卫星分别对应的卫星信号，那么可见卫星数量为4。
902、终端设备向定位设备发送回复消息。相应的，定位设备接收来自终端设备的回复消息。
其中，回复消息包括GNSS测量结果或位置信息。回复消息还包括第二信息。关于第二信息包括的内容请参阅前述步骤901中的相关介绍，这里不再赘述。

例如，第二信息包括终端设备处于室内的信息。定位设备确定终端设备处于室内。由于室内GNSS信号比较弱，因此定位设备可以为终端设备选择基于无线接入技术的定位方法。
例如，第二信息包括终端设备处于室外的信息。定位设备确定终端设备处于室外。GNSS信号质量较好，因此定位设备可以保持采用GNSS定位方法对终端设备进行定位。
例如，第二信息包括GNSS测量量的可用度较高，定位设备可以保持采用GNSS定位方法对终端设备进行定位。
例如，第二信息包括可见卫星数量大于4，定位设备可以保持采用GNSS定位方法对终端设备进行定位。

需要说明的是，定位设备可以通过隐式方式或显式方式请求第二信息。
例如，定位设备通过请求位置信息消息的GNSS请求位置信息显式请求第二信息。
例如，定位设备向终端设备发送请求位置信息消息。终端设备接收到请求位置信息消息之后，终端设备可以向定位设备反馈第二信息。也就是请求位置信息消息作为定位设备请求第二信息的一种具体形式。定位设备通过请求位置信息消息向终端设备隐式请求第二信息。
