通信方法和通信装置Communication method and communication device

本申请要求于2022年12月30日提交中国国家知识产权局、申请号为202211721778.2、申请名称为“通信方法和通信装置”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。This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 30, 2022, with application number 202211721778.2 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference in this application.

技术领域Technical Field

本申请涉及通信领域，更具体地，涉及通信领域中的通信方法和通信装置。The present application relates to the field of communications, and more specifically, to a communication method and a communication device in the field of communications.

背景技术Background technique

当终端设备附着到移动网络时，无线接入网(radio access network，RAN)设备会根据终端设备的位置信息为终端设备选择合适的核心网。在非地面网络(non terrestrial network，NTN)***下，NTN***中所部属的小区非常大，小区可能部署在靠近国家边界的地方，也有可能会覆盖不同的国家，因此会导致不同国家的核心网有可能连接到NTN***的同一个RAN设备。在这种情况下，终端设备有可能连接到错误的核心网。另外，终端设备可能会恶意伪造其位置信息，以便尝试连接到不同的核心网。When a terminal device attaches to a mobile network, the radio access network (RAN) device selects the appropriate core network for the terminal device based on the terminal device's location information. In a non-terrestrial network (NTN) system, the cells deployed in the NTN system are very large. Cells may be deployed near national borders or cover different countries, so core networks in different countries may be connected to the same RAN device in the NTN system. In this case, the terminal device may connect to the wrong core network. In addition, the terminal device may maliciously forge its location information in order to try to connect to a different core network.

第三代合作伙伴计划(3rd generation partnership project，3GPP)定义了一种基于网络验证的终端设备位置确认功能。然而，核心网在对上报的终端设备的位置信息进行验证时，终端设备可能已经发生了移动，因此核心网对终端设备的定位结果可能与上报的终端设备的位置信息差别较大，从而降低网络侧对终端设备的位置信息进行验证的可靠性。The 3rd Generation Partnership Project (3GPP) defines a terminal device location confirmation function based on network verification. However, when the core network verifies the reported terminal device location information, the terminal device may have moved. Therefore, the core network's positioning result for the terminal device may be significantly different from the reported terminal device location information, thereby reducing the reliability of the network side's verification of the terminal device location information.

The present application does not limit the terminal device to UE, and the UE can also be replaced by other terminal devices.

图1中的(R)AN表示无线接入网(radio access network，RAN)设备。RAN设备是指将终端设备接入到无线网络的设备。包括：各类基站，例如演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、下一代基站(next generation NodeB，gNodeB或gNB)、或者，其他面向未来的通信***中的基站等，此外，当eNB连接5G核心网(5G Core network，5GC)时，LTE eNB也可以称为eLTE eNB，eLTE eNB也可以认为是NR***中的基站设备；接入网设备也可以是无线中继节点、无线回传节点等设备。基站可以是宏基站，也可以是微基站或室内站等。(R)AN in Figure 1 represents radio access network (RAN) equipment. RAN equipment refers to equipment that connects terminal equipment to the wireless network. It includes: various base stations, such as evolved NodeB (eNodeB), transmission reception point (TRP), next generation NodeB (gNodeB or gNB), or other base stations in future-oriented communication systems.

Base stations can be macro base stations, micro base stations or indoor stations.

在一种网络结构中，RAN设备可以被分为两部分，集中式单元(centralized unit，CU)与分布式单元(distributed unit，DU)，如图2所示。RAN设备将部分协议层的功能放在CU集中控制，剩余的协议层的功能分布在DU中，由CU集中控制DU。CU还可以进一步地分为控制面CU(control plane CU，CU-CP)和用户面CU(user plane CU，CU-UP)。CU-CP主要负责控制面功能，主要包含无线资源控制(radio resource control，RRC)层和控制面对应的分组数据汇聚协议(packet data convergence protocol，PDCP)层，控制面对应的PDCP层(即，PDCP-C)主要负责控制面数据的加密、完整性保护、数据传输等。CU-UP主要负责用户面功能，主要包含SDAP层和用户面对应的PDCP层(即，PDCP-U)，SDAP层主要负责将核心网的数据进行处理并将数据流映射到承载。用户面对应的PDCP层主要负责数据的加解密、完整性保护、头压缩、序列号维护、数据传输等。其中，CU-UP和CU-CP通过E1接口连接。CU-CP通过NG接口和核心网连接。CU-CP通过控制面的F1接口(即F1-C)和DU连接。CU-UP通过用户面的F1接口(即F1-U)和DU连接。另外地。上述PDCP-C也可以放在CU-UP中。In a network structure, RAN equipment can be divided into two parts, centralized unit (CU) and distributed unit (DU), as shown in Figure 2. RAN equipment puts some protocol layer functions in CU for centralized control, and the remaining protocol layer functions are distributed in DU, which is centrally controlled by CU. CU can be further divided into control plane CU (control plane CU, CU-CP) and user plane CU (user plane CU, CU-UP). CU-CP is mainly responsible for control plane functions, mainly including radio resource control (RRC) layer and packet data convergence protocol (PDCP) layer corresponding to the control plane. The PDCP layer corresponding to the control plane (i.e., PDCP-C) is mainly responsible for encryption, integrity protection, data transmission, etc. of control plane data. CU-UP is mainly responsible for user plane functions, mainly including SDAP layer and PDCP layer corresponding to the user plane (i.e., PDCP-U). The SDAP layer is mainly responsible for processing the data of the core network and mapping the data flow to the bearer. The PDCP layer corresponding to the user plane is mainly responsible for data encryption and decryption, integrity protection, header compression, sequence number maintenance, data transmission, etc. Among them, CU-UP and CU-CP are connected through the E1 interface. CU-CP is connected to the core network through the NG interface. CU-CP is connected to DU through the F1 interface (ie F1-C) of the control plane. CU-UP is connected to DU through the F1 interface (ie F1-U) of the user plane. In addition. The above-mentioned PDCP-C can also be placed in CU-UP.

为了实现对UE的准确定位，可以采用不同的定位方法。下文以上行到达时间差(uplink time difference of arrival，UL-TDOA)定位方法、下行到达时间差(downlink time difference of arrival，UL-TDOA)定位方法以及多占往返时延(multi round trip time，Multi-RTT)定位方法为例，介绍定位原理。In order to achieve accurate positioning of the UE, different positioning methods can be used. The following article introduces the positioning principle by taking the uplink time difference of arrival (UL-TDOA) positioning method, the downlink time difference of arrival (UL-TDOA) positioning method and the multi-round trip time (Multi-RTT) positioning method as examples.

图4示出了采用UL-TDOA定位方法时的原理图。假设gNodeB间完全同步，UE向多个gNodeB发送定位探测参考信号(sounding reference signal，SRS)，相应地，多个gNodeB接收UE发送的上行SRS。示例性地，UE测量到的与gNodeB1、gNodeB2和gNodeB3之间的传输时延分别为t1、t2和t3。基于电磁波的传播速度和任意两个gNodeB(例如，gNodeB1和gNodeB2)接收UE发送SRS的时间差可以获得gNodeB1和gNodeB2到UE的距离差，则UE位于以gNodeB1和gNodeB2为焦点的一条双曲线上，如图4中的双曲线1。其中，gNodeB1和gNodeB2接收UE发送SRS的时间差为t2-t1＝a。另外地，基于电磁波的传播速度和任意两个gNodeB(例如，gNodeB1和gNodeB3)接收UE发送SRS的时间差可以获得gNodeB1和gNodeB3到UE的距离差，则UE也位于以gNodeB1和gNodeB3为焦点的一条双曲线上，如图4中的双曲线2。其中，gNodeB1和gNodeB3接收UE发送SRS的时间差为t3-t1＝b。双曲线1和双曲线2的交点即为UE的位置。FIG4 shows a schematic diagram of the UL-TDOA positioning method. Assuming that the gNodeBs are completely synchronized, the UE sends a sounding reference signal (SRS) to multiple gNodeBs, and correspondingly, multiple gNodeBs receive the uplink SRS sent by the UE. Exemplarily, the transmission delays measured by the UE with gNodeB1, gNodeB2, and gNodeB3 are t1, t2, and t3, respectively. Based on the propagation speed of electromagnetic waves and the time difference between any two gNodeBs (e.g., gNodeB1 and gNodeB2) receiving the SRS sent by the UE, the distance difference between gNodeB1 and gNodeB2 and the UE can be obtained. The UE is located on a hyperbola with gNodeB1 and gNodeB2 as the focus, as shown in hyperbola 1 in FIG4. Among them, the time difference between gNodeB1 and gNodeB2 receiving the SRS sent by the UE is t2-t1=a. In addition, based on the propagation speed of electromagnetic waves and the time difference between any two gNodeBs (e.g., gNodeB1 and gNodeB3) receiving the SRS sent by the UE, the distance difference between gNodeB1 and gNodeB3 and the UE can be obtained, and the UE is also located on a hyperbola with gNodeB1 and gNodeB3 as the focus, as shown in hyperbola 2 in Figure 4. Among them, the time difference between gNodeB1 and gNodeB3 receiving the SRS sent by the UE is t3-t1=b. The intersection of hyperbola 1 and hyperbola 2 is the location of the UE.

图5示出了采用DL-TDOA定位方法时的原理图。多个gNodeB向UE发送定位参考信号(positioning reference signal，PRS)，相应地，UE接收多个gNodeB发送的下行PRS。示例性地，UE测量到的与gNodeB1、gNodeB2和gNodeB3之间的传输时延分别为t4、t5和t6。基于电磁波的传播速度和UE接收的任意两个gNodeB(例如，gNodeB1和gNodeB2)发送PRS的时间差可以获得gNodeB1和gNodeB2到UE的距离差，则UE位于以gNodeB1和gNodeB2为焦点的一条双曲线上，如图5中的双曲线3。其中，UE接收gNodeB1和gNodeB2发送PRS的时间差为t5-t4＝c。另外地，基于电磁波的传播速度和UE接收任意两个gNodeB(例如，gNodeB1和gNodeB3)发送PRS的时间差可以获得gNodeB1和gNodeB3到UE的距离差，则UE也位于以gNodeB1和gNodeB3为焦点的一条双曲线上，如图5中的双曲线4。其中，gNodeB1和gNodeB3接收UE发送SRS的时间差为t6-t4＝d。双曲线3和双曲线4的交点即为UE的位置。FIG5 shows a schematic diagram of the DL-TDOA positioning method. Multiple gNodeBs send positioning reference signals (PRS) to the UE, and accordingly, the UE receives downlink PRSs sent by multiple gNodeBs. Exemplarily, the transmission delays measured by the UE with gNodeB1, gNodeB2, and gNodeB3 are t4, t5, and t6, respectively. Based on the propagation speed of electromagnetic waves and the time difference between any two gNodeBs (e.g., gNodeB1 and gNodeB2) receiving the PRSs sent by the UE, the distance difference between gNodeB1 and gNodeB2 and the UE can be obtained. The UE is located on a hyperbola with gNodeB1 and gNodeB2 as the focus, as shown in hyperbola 3 in FIG5. Among them, the time difference between the UE receiving the PRSs sent by gNodeB1 and gNodeB2 is t5-t4=c. In addition, based on the propagation speed of electromagnetic waves and the time difference when the UE receives the PRS sent by any two gNodeBs (for example, gNodeB1 and gNodeB3), the distance difference between gNodeB1 and gNodeB3 and the UE can be obtained, and the UE is also located on a hyperbola with gNodeB1 and gNodeB3 as the focus, as shown in hyperbola 4 in Figure 5. Among them, the time difference between gNodeB1 and gNodeB3 receiving the SRS sent by the UE is t6-t4=d. The intersection of hyperbola 3 and hyperbola 4 is the position of the UE.

基于上述TDOA的定位方法，需要参与UE定位的多个gNodeB的时间是同步的，同步精度越高定位性能越好。Based on the above TDOA positioning method, the time of multiple gNodeBs participating in UE positioning needs to be synchronized. The higher the synchronization accuracy, the better the positioning performance.

图6示出了采用Multi-RTT定位方法时的原理图。FIG6 shows a schematic diagram of a Multi-RTT positioning method.

多个gNodeB与UE之间互发参考信号。Multiple gNodeBs and UEs send reference signals to each other.

具体地，UE向gNodeB1发送SRS1，gNodeB1在接收到SRS1后向UE发送PRS1。UE在接收到该PRS1后，计算发送SRS1和接收PRS1之间的时差1。gNodeB1计算接收到SRS1和发送PRS1之间的时差2。UE和gNodeB1之间的距离d1＝飞行时间×光速。其中，飞行时间(time of flight，TOF)＝(时差1-时差2)/2。则UE位于以gNodeB1为圆心、d1为半径的球面1上。Specifically, the UE sends SRS1 to gNodeB1, and gNodeB1 sends PRS1 to the UE after receiving SRS1. After receiving the PRS1, the UE calculates the time difference 1 between sending SRS1 and receiving PRS1. gNodeB1 calculates the time difference 2 between receiving SRS1 and sending PRS1. The distance d1 between the UE and gNodeB1 = flight time × speed of light. Among them, the flight time (TOF) = (time difference 1-time difference 2)/2. Then the UE is located on the sphere 1 with gNodeB1 as the center and d1 as the radius.

可选地，上述具体的Multi-RTT定位方法测量了一个往返的时间戳，也可以通过测量多个往返的时间戳来计算更加精确的UE和gNodeB1之间的距离，本申请对此不作限定。 Optionally, the above-mentioned specific Multi-RTT positioning method measures a round-trip timestamp, and can also calculate a more accurate distance between the UE and gNodeB1 by measuring multiple round-trip timestamps, which is not limited in the present application.

类似地，通过上述方法分别计算出UE和gNodeB2之间的距离d2、UE和gNodeB3之间的距离d3，得到以gNodeB2为圆心、d2为半径的球面2，以及以gNodeB3为圆心、d3为半径的球面3。最终UE位于球面1、球面2、球面3的交点上，如图6所示。Similarly, the distance d2 between the UE and gNodeB2 and the distance d3 between the UE and gNodeB3 are calculated by the above method, and sphere 2 with gNodeB2 as the center and d2 as the radius and sphere 3 with gNodeB3 as the center and d3 as the radius are obtained. Finally, the UE is located at the intersection of spheres 1, 2, and 3, as shown in Figure 6.

Multi-RTT定位方法不要求多个gNodeB之间同步，可以解决多个gNodeB与UE、多个gNodeB之间不同步导致定位精度低的问题。The Multi-RTT positioning method does not require synchronization between multiple gNodeBs, and can solve the problem of low positioning accuracy caused by asynchrony between multiple gNodeBs and UEs, and between multiple gNodeBs.

非地面网络(non terrestrial network，NTN)通信，具有覆盖范围广、通信距离远、可靠性高、灵活性大、吞吐高等优点，NTN通信不受地理环境、气候条件和自然灾害的影响，已经被广泛应用于航空通信、海事通信、军事通信等领域。一方面，NTN可以为地面网络难以覆盖的区域(例如，海洋、森林、沙漠或偏远地区等)提供通信服务；另一方面，NTN可以增强5G通信的可靠性，例如，可以为火车、飞机等高速移动场景下的用户提供更稳定的通信服务；再一方面，NTN还可以提供更多的数据传输资源，支持更多数量的连接。因此，将NTN引入到未来的通信***中(例如，5G通信***)能极大地提高用户体验。本申请中以下描述以卫星通信作为NTN通信为例进行描述，也可以扩展到其它非地面网络，例如，高空平台(high altitude platform station，HAPS)网络。Non-terrestrial network (NTN) communication has the advantages of wide coverage, long communication distance, high reliability, high flexibility, and high throughput. NTN communication is not affected by geographical environment, climatic conditions and natural disasters, and has been widely used in aviation communication, maritime communication, military communication and other fields. On the one hand, NTN can provide communication services for areas that are difficult to cover by terrestrial networks (for example, oceans, forests, deserts or remote areas); on the other hand, NTN can enhance the reliability of 5G communication, for example, it can provide more stable communication services for users in high-speed mobile scenarios such as trains and airplanes; on the other hand, NTN can also provide more data transmission resources and support a larger number of connections. Therefore, introducing NTN into future communication systems (for example, 5G communication systems) can greatly improve user experience. The following description in this application takes satellite communication as an example of NTN communication, and can also be extended to other non-terrestrial networks, for example, high altitude platform station (HAPS) networks.

通常来说，卫星的轨道越高，该卫星的覆盖面积越大，但是通信的时延也越长。根据卫星的轨道高度，卫星可以分为：(1)低地球轨道(low earth orbit，LEO)卫星，LEO卫星的轨道高度大约为160公里(km)～2000km；(2)中地球轨道(middle earth orbit，MEO)卫星，MEO卫星的轨道高度大约为2000km～35786km；(3)静止地球轨道(geostationary earth orbit，GEO)，GEO卫星的轨道高度大约为35786km。其中，LEO卫星和MEO卫星统称为非静止轨道(non geostationary satellite Orbit，NGSO)卫星，运行在此轨道上的卫星相对地面高速移动。GEO卫星为同步地球卫星轨道，运行在此轨道上的卫星相对地面是静止的。NGSO卫星的通信时延相比GEO卫星的通信时延较低，因此很多卫星通信提供商选择NGSO卫星作为通信卫星。Generally speaking, the higher the satellite's orbit, the larger the satellite's coverage area, but the longer the communication delay. According to the satellite's orbital altitude, satellites can be divided into: (1) low earth orbit (LEO) satellites, the orbital altitude of LEO satellites is about 160 kilometers (km) to 2000km; (2) medium earth orbit (MEO) satellites, the orbital altitude of MEO satellites is about 2000km to 35786km; (3) geostationary earth orbit (GEO), the orbital altitude of GEO satellites is about 35786km. Among them, LEO satellites and MEO satellites are collectively referred to as non-geostationary satellite orbit (NGSO) satellites, and satellites operating in this orbit move at high speed relative to the ground. GEO satellites are synchronous earth satellite orbits, and satellites operating in this orbit are stationary relative to the ground. The communication delay of NGSO satellites is lower than that of GEO satellites, so many satellite communication providers choose NGSO satellites as communication satellites.

对于NGSO卫星，根据卫星的波束是否随卫星移动，进一步地可以分为地球移动小区(earth moving cell)和地球固定小区(earth fixed cell)。对于地球移动小区，卫星所服务的小区相对地面是移动的，卫星的波束指向跟随卫星移动；对于地球固定小区，卫星所服务的小区在一定时间内相对地面是固定的，卫星天线可以利用波束赋形能力在一定时间内将波束指向固定在地面的某一片区域。For NGSO satellites, they can be further divided into earth moving cells and earth fixed cells according to whether the satellite beam moves with the satellite. For earth moving cells, the cell served by the satellite is moving relative to the ground, and the satellite beam is directed to follow the satellite movement; for earth fixed cells, the cell served by the satellite is fixed relative to the ground within a certain period of time, and the satellite antenna can use the beamforming capability to point the beam to a certain area fixed on the ground within a certain period of time.

上述NTN通信有两种典型的传输类型：第一种是透明转发，第二种是非透明转发，非透明转发也可以称为再生(regenerative)形式。The above-mentioned NTN communication has two typical transmission types: the first is transparent forwarding, and the second is non-transparent forwarding, which can also be called regenerative form.

图7示出了卫星采用透明转发的网络架构的示意图。卫星转发地面网络设备(例如，RAN设备)的小区的信息。卫星对于信号来说可以认为是透明的。信号在卫星上进行频率的转换、信号的放大等过程。FIG7 is a schematic diagram of a network architecture in which a satellite adopts transparent forwarding. The satellite forwards the cell information of the ground network equipment (e.g., RAN equipment). The satellite can be considered transparent to the signal. The signal undergoes frequency conversion, signal amplification, and other processes on the satellite.

卫星采用透明转发方式时，DN与UE之间的下行数据传输分别经过DN、5G核心网设备(例如，可以是UPF)、RAN设备(例如，可以是gNodeB)、NTN网关(NTN gateway)、卫星、UE；DN与UE之间的上行数据传输分别经过UE、卫星、NTN网关(NTN gateway)、RAN设备(例如，可以是gNodeB)、5G核心网设备(例如，可以是UPF)、DN。When the satellite adopts transparent forwarding mode, the downlink data transmission between DN and UE passes through DN, 5G core network equipment (for example, it can be UPF), RAN equipment (for example, it can be gNodeB), NTN gateway (NTN gateway), satellite, and UE respectively; the uplink data transmission between DN and UE passes through UE, satellite, NTN gateway (NTN gateway), RAN equipment (for example, it can be gNodeB), 5G core network equipment (for example, it can be UPF), and DN respectively.

图8示出了卫星采用非透明转发的网络架构的示意图。当卫星采用非透明转发的方式时，卫星又可以分为不具有星间链路(inter satellite link，ISL)的卫星以及具有ISL的卫星。具有ISL的卫星之间可以用接口Xn交互数据。FIG8 is a schematic diagram of a network architecture in which satellites use non-transparent forwarding. When satellites use non-transparent forwarding, satellites can be divided into satellites without inter-satellite links (ISL) and satellites with ISL. Satellites with ISL can exchange data using interface Xn.

卫星采用非透明转发方式时，DN与UE之间的下行数据传输分别经过DN、5G核心网设备(例如，可以是UPF)、NTN网关(NTN gateway)、卫星、UE；DN与UE之间的上行数据传输分别经过UE、卫星、NTN网关(NTN gateway)、5G核心网设备(例如，可以是UPF)、DN。When the satellite adopts a non-transparent forwarding mode, the downlink data transmission between DN and UE passes through DN, 5G core network equipment (for example, it can be UPF), NTN gateway (NTN gateway), satellite, and UE respectively; the uplink data transmission between DN and UE passes through UE, satellite, NTN gateway (NTN gateway), 5G core network equipment (for example, it can be UPF), and DN respectively.

当UE附着到移动网络时，RAN设备会根据UE的位置信息为UE选择合适的核心网。在NTN通信***下，NTN***中所部署的小区非常大，小区可能部署在靠近国家边界的地方，也有可能会覆盖不同的国家，因此会导致不同国家的核心网有可能连接到NTN***的同一个RAN设备。在这种情况下，UE有可能连接到错误的核心网。另外，UE可能会恶意伪造其位置信息，以便尝试连接到不同的核心网。When a UE attaches to a mobile network, the RAN device selects a suitable core network for the UE based on the UE's location information. In the NTN communication system, the cells deployed in the NTN system are very large. Cells may be deployed near national borders or cover different countries, so core networks in different countries may be connected to the same RAN device in the NTN system. In this case, the UE may be connected to the wrong core network. In addition, the UE may maliciously forge its location information in order to try to connect to a different core network.

UE的位置信息可以通过GNSS定位获取并由UE上报给RAN设备，但是RAN设备仅依赖UE报告的基于GNSS的位置信息是不可靠的。主要是因为UE上报的位置信息可能被用户或第三方恶意修改而不可信，或者，GNSS信号受到干扰，导致UE的位置信息不可靠等。The location information of the UE can be obtained through GNSS positioning and reported by the UE to the RAN equipment. However, the RAN equipment is unreliable if it only relies on the GNSS-based location information reported by the UE. This is mainly because the location information reported by the UE may be maliciously modified by the user or a third party and is unreliable, or the GNSS signal is interfered with, resulting in unreliable UE location information.

因此，可以采用基于网络验证的UE位置确认功能。网络侧使用UE的服务小区标识验证UE上报的位置信息是否可靠，网络侧使用UE的服务小区标识确认的UE的位置精度与小区的大小一致。小区越大，网络侧使用UE的服务小区标识确认的UE的位置精度越低；小区越小，网络侧使用UE的服务小区标识确认的UE的位置精度越高。这种方法在地面网络有效，但是NTN中的小区半径一般为几十到几百公里，远大于地面网络中的小区规模。因此，基于UE的服务小区标识验证UE上报的位置信息是否可靠的方法无法得到所需要的验证精度。Therefore, the UE location confirmation function based on network verification can be used. The network side uses the UE's serving cell identifier to verify whether the location information reported by the UE is reliable. The location accuracy of the UE confirmed by the network side using the UE's serving cell identifier is consistent with the size of the cell. The larger the cell, The smaller the cell, the higher the accuracy of the UE's location confirmed by the network side using the UE's service cell identifier. This method is effective in ground networks, but the cell radius in NTN is generally tens to hundreds of kilometers, which is much larger than the cell scale in ground networks. Therefore, the method of verifying whether the location information reported by the UE is reliable based on the UE's service cell identifier cannot obtain the required verification accuracy.

另外，也可以通过网络侧对UE的定位结果来验证UE上报的位置信息是否可靠。具体地，如果网络侧对UE的定位结果与UE上报的位置信息的位置差距小于门限，例如5km～10km，可以认为网络侧对UE的位置验证通过，否则不通过。其中，网络侧对UE的定位方法本申请不作限定。In addition, the reliability of the location information reported by the UE can also be verified by the positioning result of the UE on the network side. Specifically, if the location difference between the positioning result of the UE on the network side and the location information reported by the UE is less than a threshold, such as 5km to 10km, it can be considered that the location verification of the UE on the network side is passed, otherwise it is not passed. Among them, the positioning method of the UE on the network side is not limited in this application.

当UE处于单星覆盖时，该单星为上述的NGSO卫星，相对地面高速移动。测量UE与同一卫星在不同时刻的距离，如图9所示。此处以上述Multi-RTT定位方法举例进行说明，但是本申请的定位方法并不限定于此。When the UE is in single-satellite coverage, the single satellite is the NGSO satellite mentioned above, which moves at high speed relative to the ground. The distance between the UE and the same satellite at different times is measured, as shown in Figure 9. The above-mentioned Multi-RTT positioning method is used as an example for illustration, but the positioning method of the present application is not limited thereto.

假如UE静止，卫星沿着图9所示的方向移动。测量UE与同一卫星在不同时刻的距离，可以等效为多星的场景。在第一时刻测量卫星与UE之间的距离，在第二时刻测量卫星与UE之间的距离，第三时刻测量卫星与UE之间的距离，根据上述Multi-RTT定位方法确定UE的位置。网络侧在确定UE的定位结果后会对UE上报的位置信息进行验证。Assume that the UE is stationary and the satellite moves in the direction shown in Figure 9. Measuring the distance between the UE and the same satellite at different times can be equivalent to a multi-satellite scenario. The distance between the satellite and the UE is measured at the first moment, the distance between the satellite and the UE is measured at the second moment, and the distance between the satellite and the UE is measured at the third moment. The position of the UE is determined according to the above Multi-RTT positioning method. After determining the positioning result of the UE, the network side will verify the location information reported by the UE.

然而，网络侧在触发验证时，当上报的UE的位置信息对应的时间与网络侧对UE进行定位的时间的时间间隔比较大时，可能会导致上报的UE的位置信息无效，从而降低网络侧对UE的位置信息进行验证的可靠性。However, when the network side triggers verification, if the time interval between the time corresponding to the reported UE location information and the time when the network side locates the UE is relatively large, the reported UE location information may become invalid, thereby reducing the reliability of the network side's verification of the UE location information.

因此，本申请提供一种对UE的位置信息进行验证的方法。Therefore, the present application provides a method for verifying the location information of a UE.

在介绍本申请对UE的位置信息进行验证的方法之前，先介绍一下网络侧对UE进行定位的方法100，如图10所示。Before introducing the method for verifying the location information of the UE in the present application, a method 100 for positioning the UE on the network side is first introduced, as shown in FIG. 10 .

步骤S104，AMF发起位置服务请求，向LMF发送位置服务请求消息。Step S104: AMF initiates a location service request and sends a location service request message to LMF.

一种实施方式中，在步骤S104之前，步骤S100，5G核心网的其他实体(例如网关移动位置中心gateway mobile location centre，GMLC)发起位置服务请求，并将位置服务请求消息发送给AMF。即位置服务请求是5G核心网的其他实体发起的。In one implementation, before step S104, in step S100, other entities of the 5G core network (e.g., gateway mobile location centre, GMLC) initiate a location service request and send the location service request message to the AMF. That is, the location service request is initiated by other entities of the 5G core network.

具体地，LCS客户端可以向GMLC发送位置服务请求消息，由GMLC将该位置服务请求消息发送给AMF。LCS客户端(LCS client)也可以是LCS实体(LCS entities)。Specifically, the LCS client can send a location service request message to the GMLC, and the GMLC sends the location service request message to the AMF. The LCS client (LCS client) can also be an LCS entity (LCS entities).

另一种实施方式中，在步骤S104之前，步骤S102，UE发起位置服务请求，并通过非接入层(non access service，NAS)信令向AMF发送位置服务请求消息。即位置服务请求是UE发起的。In another implementation, before step S104, in step S102, the UE initiates a location service request and sends a location service request message to the AMF via non-access layer (NAS) signaling. That is, the location service request is initiated by the UE.

又一种实施方式中，在步骤S104之前，AMF也可以为了一些位置服务的需要自己确定要针对UE发起位置服务请求。即位置服务请求是AMF自己发起的。In another implementation, before step S104, the AMF may also determine to initiate a location service request for the UE for some location service needs, that is, the location service request is initiated by the AMF itself.

步骤S106，若LMF根据当前采用的定位方法判定需要RAN设备参与此次定位过程，则LMF与RAN设备交互定位相关的信息。Step S106: If the LMF determines that the RAN device needs to participate in the positioning process according to the currently used positioning method, the LMF exchanges positioning-related information with the RAN device.

示例性地，LMF可以指示RAN设备当前的定位方法、测量配置，并从RAN设备处获取定位测量参数的结果。Exemplarily, the LMF may indicate the current positioning method and measurement configuration of the RAN device, and obtain the results of the positioning measurement parameters from the RAN device.

具体地，不同的定位方法所需测量的定位测量参数可能是不同的。该定位测量参数包括参考信号的传输时间、信号强度、到达角、离开角等。Specifically, different positioning methods may require different positioning measurement parameters, including the transmission time, signal strength, arrival angle, departure angle, etc. of the reference signal.

可选地，步骤S108，若LMF根据当前采用的定位方法判定需要UE参与此次定位过程，则LMF通过NAS信令与UE交互定位相关的信息。Optionally, in step S108, if the LMF determines that the UE needs to participate in the positioning process according to the currently used positioning method, the LMF exchanges positioning-related information with the UE through NAS signaling.

例如LMF从UE侧获得位置信息、获取定位测量结果，UE从LMF侧获得定位辅助数据等。For example, the LMF obtains location information and positioning measurement results from the UE side, and the UE obtains positioning assistance data from the LMF side.

步骤S110，LMF根据获取到的定位测量的数据确定UE的定位结果。Step S110: LMF determines the positioning result of the UE according to the acquired positioning measurement data.

步骤S112，LMF通过位置服务请求反馈消息将所确定的上述UE的定位结果发送给AMF。Step S112, LMF sends the determined positioning result of the above UE to AMF through a location service request feedback message.

上述UE的定位结果可以是定位成功指示或定位失败指示，UE的定位位置等。The positioning result of the above UE may be a positioning success indication or a positioning failure indication, the positioning position of the UE, etc.

可选地，步骤S114，若上述位置服务请求是由5G核心网的其他实体发起的，则AMF向步骤S100中5G核心网的其他实体发送位置服务反馈消息，该消息中可以携带一些定位结果，例如UE的定位位置等。Optionally, in step S114, if the location service request is initiated by other entities in the 5G core network, the AMF sends a location service feedback message to other entities in the 5G core network in step S100, which may carry some positioning results, such as the positioning position of the UE.

可选地，步骤S116，若上述位置服务请求是由UE发起的，则AMF向UE发送位置服务反馈消息，该消息中可以携带一些定位结果，例如UE的定位位置等。 Optionally, in step S116, if the location service request is initiated by the UE, the AMF sends a location service feedback message to the UE, which may carry some positioning results, such as the UE's positioning location.

可以理解，以上描述的AMF以及LMF仅为执行定位方法的网元的举例，可以由其他网元具有定位功能的网元代替，本申请不做限定。It can be understood that the AMF and LMF described above are merely examples of network elements that execute the positioning method and can be replaced by other network elements with positioning functions, and this application does not limit this.

接下来，本申请介绍一种对终端设备的位置信息进行验证的方法200，如图11所示。Next, the present application introduces a method 200 for verifying the location information of a terminal device, as shown in FIG11 .

步骤S206，第一网元触发对终端设备的位置验证，第一网元从接入网设备获取终端设备的位置信息。Step S206: The first network element triggers location verification of the terminal device, and the first network element obtains location information of the terminal device from the access network device.

具体地，可以以第一网元触发验证的时刻作为参考时间，记为T0。以DT为时间段，那么上述第一时段可以为[T0-DT，T0+DT]。第一时段可以分为[T0-DT，T0]以及[T0，T0+DT]两个时间段。上述第一网元可以向接入网设备指示时间段DT的取值，或者，上述时间段DT的取值也可以是协议规定的默认值。Specifically, the moment when the first network element triggers the verification can be used as a reference time, denoted as T0. Taking DT as the time period, the first time period can be [T0-DT, T0+DT]. The first time period can be divided into two time periods: [T0-DT, T0] and [T0, T0+DT]. The first network element can indicate the value of the time period DT to the access network device, or the value of the time period DT can also be the default value specified by the protocol.

在一个实现方式中，第一网元还可以从接入网设备获取终端设备的位置信息对应的时间。该终端设备的位置信息对应的时间可以是该终端设备的位置的测量时间，或者，该终端设备的位置信息对应的时间可以是该终端设备的位置的获取时间。In one implementation, the first network element may also obtain the time corresponding to the location information of the terminal device from the access network device. The time corresponding to the location information of the terminal device may be the measurement time of the location of the terminal device, or the time corresponding to the location information of the terminal device may be the acquisition time of the location of the terminal device.

在一个实现方式中，第一网元还可以向接入网设备指示第一位置精度，该第一位置精度用于指示接入网设备上报的终端设备的位置信息满足第一位置精度的要求。In one implementation, the first network element may also indicate a first location accuracy to the access network device, where the first location accuracy is used to indicate that the location information of the terminal device reported by the access network device meets the first location accuracy requirement.

具体地，该第一位置精度可以是指终端设备的位置之间间隔的距离，例如以公里(km)为第一位置精度的单位，比如设置为2公里或3km，则接入网设备上报的终端位置信息可以指示间隔为2km或3km的终端设备位置；或者，该第一位置精度也可以是间隔距离的区间，比如设置为[2km,3km]，则接入网设备上报的终端位置信息可以指示间隔为2km至3km之间的终端设备位置。该第一位置精度可以根据实际需要由第一网元灵活设定。Specifically, the first location accuracy may refer to the distance between the locations of the terminal devices, for example, with kilometers (km) as the unit of the first location accuracy, for example, if it is set to 2 kilometers or 3km, the terminal location information reported by the access network device may indicate the terminal device locations with an interval of 2km or 3km; or, the first location accuracy may also be an interval of the interval distance, for example, if it is set to [2km, 3km], the terminal location information reported by the access network device may indicate the terminal device locations with an interval between 2km and 3km. The first location accuracy may be flexibly set by the first network element according to actual needs.

步骤S208，第一网元向第二网元发送第一信息，该第一信息用于请求第二网元对终端设备进行定位以获得第一定位结果。Step S208: The first network element sends first information to the second network element, where the first information is used to request the second network element to locate the terminal device to obtain a first positioning result.

具体地，该第二网元可以是LMF，也可以是其他具有定位功能的网元。Specifically, the second network element may be a LMF, or may be other network elements with a positioning function.

具体地，上述第一时段与上述第二网元对终端设备进行定位的时间的间隔小于第一阈值。其中，对终端设备进行定位的时间可以是某个时刻，也可以是某个时间段，也可以是某个时间段内的任意时刻，本申请对此不作限定。Specifically, the interval between the first time period and the time when the second network element locates the terminal device is less than the first threshold. The time for locating the terminal device can be a certain moment, a certain time period, or any moment within a certain time period, which is not limited in this application.

示例性地，上述第一阈值可以根据终端设备的移动速度确定。例如，当终端设备的移动速度慢，第一阈值可以设定的大一些；当终端设备的移动速度快时，第一阈值可以设定的小一些。具体设定的数值根据实际需要由第一网元进行设定，本申请不作限定。Exemplarily, the first threshold value may be determined according to the moving speed of the terminal device. For example, when the moving speed of the terminal device is slow, the first threshold value may be set larger; when the moving speed of the terminal device is fast, the first threshold value may be set smaller. The specific set value is set by the first network element according to actual needs, and this application does not limit it.

在一个实现方式中，上述第一信息用于请求第二网元在第二时段内对终端设备进行定位以获得第一定位结果。其中，第二时段也可以称为第二时间范围。In one implementation, the first information is used to request the second network element to locate the terminal device within a second time period to obtain a first positioning result. The second time period may also be referred to as a second time range.

示例性地，上述第一时段的起始时刻与上述第二时段的起始时刻的时间间隔小于上述第一阈值，或者，上述第一时段的起始时刻与上述第二时段的结束时刻的时间间隔小于上述第一阈值，或者，上述第一时段的结束时刻与上述第二时段的起始时刻的时间间隔小于上述第一阈值，或者，上述第一时段的结束时刻与上述第二时段的结束时刻的时间间隔小于上述第一阈值。从以上示例可知，时间间隔可以采用不同的定义方式，对于不同的时间间隔的示例中，第一阈值的取值可以相同，也可以不同。Exemplarily, the time interval between the start time of the first time period and the start time of the second time period is less than the first threshold, or the time interval between the start time of the first time period and the end time of the second time period is less than the first threshold, or the time interval between the end time of the first time period and the start time of the second time period is less than the first threshold, or the end time of the first time period is less than the first threshold. The time interval between the end time of the second period and the end time of the second period is less than the first threshold. From the above examples, it can be seen that the time interval can be defined in different ways, and for examples of different time intervals, the value of the first threshold can be the same or different.

示例性地，如果上述第一时段的起始时刻与上述第二时段的起始时刻的时间间隔小于第一阈值X，上述第一时段的起始时刻与上述第二时段的结束时刻的时间间隔小于上述第一阈值Y，那么可以设定该X小于Y。在不同的应用时刻，该X与该Y也可以设定相同，或者也可以设定该X大于该Y。Exemplarily, if the time interval between the start time of the first time period and the start time of the second time period is less than the first threshold value X, and the time interval between the start time of the first time period and the end time of the second time period is less than the first threshold value Y, then X can be set to be less than Y. At different application times, X and Y can also be set to be the same, or X can also be set to be greater than Y.

终端设备在由单个卫星服务场景(简称单星场景)下，卫星相对地面高速移动，因此在对终端设备进行定位时可能会面临服务卫星的切换。该卫星可以认为是NTN设备的一例。When a terminal device is served by a single satellite (single satellite scenario for short), the satellite moves at high speed relative to the ground, so when positioning the terminal device, the serving satellite may be switched. This satellite can be considered as an example of NTN equipment.

在单星场景中，作为本申请的一个实现方式中，在步骤S208之后，所述方法还包括，步骤S210，接入网设备向第二网元发送第二信息，该第二信息用于辅助第二网元进行测量配置。In a single-satellite scenario, as an implementation of the present application, after step S208, the method further includes, in step S210, the access network device sends second information to the second network element, where the second information is used to assist the second network element in performing measurement configuration.

具体地，上述第二信息所包括的对终端设备进行定位的总时长、对终端设备进行测量的测量时间间隔是接入网设备预期的第二网元进行测量配置的参数。上述第二信息所包括的NTN设备的切换信息、切换前NTN设备的信息和切换后NTN设备的信息用于辅助第二网元进行测量配置，以尽量避免在NTN设备(例如，卫星)切换时进行测量。Specifically, the total duration of positioning the terminal device and the measurement time interval for measuring the terminal device included in the second information are parameters expected by the access network device for the second network element to perform measurement configuration. The switching information of the NTN device, the information of the NTN device before the switching, and the information of the NTN device after the switching included in the second information are used to assist the second network element in performing measurement configuration to avoid performing measurements when the NTN device (e.g., satellite) is switched as much as possible.

具体地，接入网设备根据上述第一配置信息、终端设备根据上述第二配置信息来对终端设备的位置进行测量。Specifically, the access network device measures the position of the terminal device according to the first configuration information, and the terminal device measures the position of the terminal device according to the second configuration information.

上述接入网设备和/或上述终端设备将测量的结果上报给第二网元。如果上述接入网设备与上述终端设备在测量的过程中发生了NTN设备(例如，卫星)的切换，可能会导致测量结果的不准确。因此，在一个实现方式中，在步骤S212与步骤S214之后，所述方法还包括步骤S216，接入网设备向第二网元发送第三信息，该第三信息用于辅助第二网元对测量结果进行修正。The access network device and/or the terminal device reports the measurement result to the second network element. If the NTN device (e.g., satellite) is switched between the access network device and the terminal device during the measurement, the measurement result may be inaccurate. Therefore, in one implementation, after step S212 and step S214, the method further includes step S216, where the access network device sends third information to the second network element, and the third information is used to assist the second network element in correcting the measurement result.

具体地，上述第三信息包括以下至少一项信息：Specifically, the third information includes at least one of the following information:

The switching information of the NTN device, the information of the NTN device before switching, and the information of the NTN device after switching included in the third information are used to assist the second network element in correcting the measurement result to obtain a more accurate first positioning result.

具体地，该第一定位结果可以是第二网元根据第一网元发送的第一信息指示而获取的，该获取的第一定位结果还可以根据接入网设备发送的第三信息进行修正，不做限定。Specifically, the first positioning result may be obtained by the second network element according to the first information indication sent by the first network element, and the obtained first positioning result may also be modified according to the third information sent by the access network device, without limitation.

步骤S220，第一网元根据该第一定位结果对上述终端设备的位置信息进行验证。Step S220: The first network element verifies the location information of the terminal device according to the first positioning result.

通过上述方案200，可以使得第一网元对接入网设备上报的终端设备的位置信息进行验证时终端设备的位置信息有效，提升第一网元对终端设备的位置信息进行验证的可靠性。另外，可以使得接入网设备上报的终端设备的位置信息满足第一网元的验证精度要求，避免接入网设备上报的终端设备的位置精度太低导致第一网元无法进行验证的问题。Through the above scheme 200, the location information of the terminal device reported by the access network device can be verified by the first network element, and the reliability of the first network element verifying the location information of the terminal device can be improved. The reported location information of the terminal device meets the verification accuracy requirement of the first network element, thereby avoiding the problem that the location accuracy of the terminal device reported by the access network device is too low, resulting in the first network element being unable to perform verification.

上述方法200是由第一网元触发的验证，还可以通过接入网设备来触发验证，如图12所述的方法300。The above method 200 is a verification triggered by the first network element, and verification can also be triggered by an access network device, such as method 300 shown in FIG. 12 .

The access network device instructs the first network element to verify the location information of the terminal device within the first time period by sending information of the first time. For example, the information of the first time period may include the start time and the end time of the first time period.

具体地，以接入网设备触发验证的时刻为参考时间，记为T1。上述第一时段可以标识为[T1，T2]。该T2时刻为第一网元对终端设备的位置信息进行验证的终止时刻。Specifically, the time when the access network device triggers the verification is taken as the reference time, which is recorded as T1. The first time period can be identified as [T1, T2]. The time T2 is the end time when the first network element verifies the location information of the terminal device.

在一个示例中，第一信息还可以包括终端设备的位置信息对应的时间。该终端设备的位置信息对应的时间可以是该终端设备的位置的测量时间，或者，该终端设备的位置信息对应的时间可以是该终端设备的位置的获取时间。In one example, the first information may also include the time corresponding to the location information of the terminal device.

上述接入网设备和/或上述终端设备将测量的结果上报给第二网元。如果上述接入网设备与上述终端设备在测量的过程中发生了NTN设备(例如，卫星)的切换，可能会导致测量结果的不准确。The access network device and/or the terminal device reports the measurement result to the second network element. If the NTN device (eg, satellite) is switched between the access network device and the terminal device during the measurement, the measurement result may be inaccurate.

It can be understood that the method 400 and the method 500 introduced below are based on the method 200 and the method 300, and the description of the communication method provided by the present application is based on the method 200 and the method 300. The embodiments can refer to each other, and the contents described in the aforementioned embodiments will not be repeated.

本申请介绍一种对UE的位置信息进行验证的方法400，如图13所示。 The present application introduces a method 400 for verifying the location information of a UE, as shown in FIG13 .

步骤S400，AMF触发对UE的位置信息的验证，向LMF发送位置确认请求消息，该位置确认请求消息用于请求LMF对UE进行定位。相应地，LMF接收AMF发送的该位置确认请求消息。Step S400, AMF triggers verification of the location information of the UE and sends a location confirmation request message to LMF, where the location confirmation request message is used to request LMF to locate the UE. Correspondingly, LMF receives the location confirmation request message sent by AMF.

一种实施方式中，AMF是由于收到5G核心网的其他实体的位置服务请求或位置信息的验证请求而触发对UE的位置信息的验证；In one implementation, the AMF triggers verification of the UE's location information due to receiving a location service request or a location information verification request from other entities in the 5G core network;

另一种实施方式中，AMF为了一些位置服务的需要而自己确定要触发对UE的位置信息的验证；In another implementation, the AMF determines on its own to trigger verification of the UE's location information for some location services;

另一种实施方式中，AMF从RAN设备收到了指示RAN设备从UE侧收到了UE上报的位置之后(例如AMF从RAN设备收到了RAN设备根据UE上报的位置而确定的跟踪区域码(tracking area code，TAC)之后，或者AMF从RAN设备收到了RAN设备根据UE上报的位置而确定的映射的小区标识)，AMF确定需要触发对UE的位置信息的验证。由于对UE的位置信息的验证主要是验证UE上报的位置，AMF只有在确定RAN设备从UE收到了UE上报的位置之后才触发验证，这样可以减少AMF触发验证的次数，减少验证带来的开销。In another implementation, after the AMF receives from the RAN device an indication that the RAN device has received the location reported by the UE from the UE side (for example, after the AMF receives from the RAN device a tracking area code (TAC) determined by the RAN device based on the location reported by the UE, or the AMF receives from the RAN device a mapped cell identifier determined by the RAN device based on the location reported by the UE), the AMF determines that it is necessary to trigger verification of the location information of the UE. Since verification of the location information of the UE is mainly to verify the location reported by the UE, the AMF triggers verification only after determining that the RAN device has received the location reported by the UE from the UE, which can reduce the number of times the AMF triggers verification and reduce the overhead caused by verification.

步骤S402，AMF向RAN设备发送位置请求消息，该位置请求消息用于请求RAN设备上报UE的位置信息。Step S402: The AMF sends a location request message to the RAN device, where the location request message is used to request the RAN device to report the location information of the UE.

可选地，上述位置请求消息包括AMF对上报的UE位置精度的要求，即上述第一位置精度的一例。Optionally, the location request message includes the AMF's requirement for the reported UE location accuracy, which is an example of the first location accuracy.

示例性地，RAN设备可以向AMF上报UE的位置，或者，RAN设备可以向AMF上报满足位置精度要求的小区标识(例如可以为RAN设备根据UE上报的位置而确定的映射的小区标识)，以便AMF根据小区标识获取UE的位置。Exemplarily, the RAN device may report the location of the UE to the AMF, or the RAN device may report a cell identifier that meets the location accuracy requirements to the AMF (for example, a mapped cell identifier determined by the RAN device based on the location reported by the UE), so that the AMF obtains the location of the UE based on the cell identifier.

具体地，上述UE的位置信息可以是已知的位置信息，例如，UE的位置信息可以是预先配置的地理位置坐标信息(geographic coordinate point，GCP)，也可以是运营商配置的位置信息(例如TAC信息，或映射的小区标识)，还可以是通过定位方法测量或计算或估计的位置信息，例如，可以是通过以下一种或多种定位方法测量或计算或估计的位置信息：Specifically, the location information of the UE may be known location information, for example, the location information of the UE may be pre-configured geographic coordinate point (GCP), or may be location information configured by an operator (for example, TAC information, or a mapped cell identifier), or may be location information measured, calculated, or estimated by a positioning method, for example, may be location information measured, calculated, or estimated by one or more of the following positioning methods:

全球导航卫星***(global navigation satellite system，GNSS)、动态实时差分(real-time kinematic，RTK)、雷达(light detection and ranging，LIDAR)、观察达到时间差(observed time difference of arrival，OTDOA)、UL-TDOA、DL-TDOA、上行到达角度(uplink angle of arrival，UL-AoA)、下行到达角度(downlink angle of arrival，DL-AoA)、下行偏离角度(downlink angle of departure，DL-AoD)、Multi-RTT、TDOA、增强型小区标识(enhanced cell identification，ECID)、基于WLAN的定位方法、基于蓝牙的定位方法、地面信标***(terrestrial beacon system，TBS)的定位方法、基于传感器的定位方法等。Global navigation satellite system (GNSS), real-time kinematic (RTK), light detection and ranging (LIDAR), observed time difference of arrival (OTDOA), UL-TDOA, DL-TDOA, uplink angle of arrival (UL-AoA), downlink angle of arrival (DL-AoA), downlink angle of departure (DL-AoD), Multi-RTT, TDOA, enhanced cell identification (ECID), WLAN-based positioning method, Bluetooth-based positioning method, terrestrial beacon system (TBS) positioning method, sensor-based positioning method, etc.

具体地，上述位置请求消息还可以指示第一时段。也就是说，AMF请求RAN设备上报的位置信息是UE在第一时段内获取的。Specifically, the location request message may also indicate the first time period. That is, the location information reported by the AMF requesting the RAN device is obtained by the UE within the first time period.

具体地，可以以AMF触发验证的时刻为参考时间，记为T0。以DT为时间段，那么上述第一时段可以为[T0-DT，T0+DT]。另一种实施方式中，第一时段可以分为[T0-DT，T0]以及[T0，T0+DT]两个时间段。上述位置请求消息可以指示时间段DT的取值。可选地，上述时间段DT的取值也可以是协议规定的默认值。Specifically, the moment when the AMF triggers the verification can be used as the reference time, denoted as T0. Taking DT as the time period, the first time period can be [T0-DT, T0+DT]. In another implementation, the first time period can be divided into two time periods: [T0-DT, T0] and [T0, T0+DT]. The location request message can indicate the value of the time period DT. Optionally, the value of the time period DT can also be the default value specified by the protocol.

关于第一时段的介绍还可以参考前述方法200中的相关内容。For the introduction of the first period, please refer to the relevant content in the aforementioned method 200.

可选地，所述方法还包括步骤S404，若是RAN设备在收到AMF发送的位置请求消息时不存在满足[T0-DT，T0]时间段的UE的位置信息，则RAN设备向UE发送位置请求消息，该位置请求消息指示UE上报最新的位置信息，并在步骤S406接收UE发送的最新的位置信息。这种情况下，RAN设备向AMF上报最新的UE的位置信息的时刻在[T0，T0+DT]时间范围内。Optionally, the method further includes step S404, if the RAN device does not have the UE location information that satisfies the [T0-DT, T0] time period when receiving the location request message sent by the AMF, the RAN device sends a location request message to the UE, the location request message instructs the UE to report the latest location information, and receives the latest location information sent by the UE in step S406. In this case, the time when the RAN device reports the latest UE location information to the AMF is within the [T0, T0+DT] time range.

步骤S408，若是RAN设备在收到AMF发送的位置请求消息时存在满足[T0-DT，T0]时间段的UE的位置信息，则RAN设备在位置请求反馈消息中上报[T0-DT，T0]时间范围内的UE的位置信息。Step S408: If the RAN device has the location information of the UE that satisfies the time period [T0-DT, T0] when receiving the location request message sent by the AMF, the RAN device reports the location information of the UE within the time range [T0-DT, T0] in the location request feedback message.

可选地，RAN设备在上报UE的位置信息时还可以携带UE的该位置信息的测量时间。Optionally, when reporting the location information of the UE, the RAN device may also carry the measurement time of the location information of the UE.

可选地，上述第一时段也可以是协议规定的默认值。Optionally, the first time period may also be a default value specified by the protocol.

可选地，当RAN设备无法获得符合要求的UE的位置信息时，RAN设备可以向AMF发送UE的位置信息不可用的指示信息，AMF释放该UE。RAN设备无法获得符合要求的UE的位置信息的情况可以是：UE没有上报最新的位置信息，或者，UE无法获得最新的位置信息等。Optionally, when the RAN device cannot obtain the location information of the UE that meets the requirements, the RAN device may send an indication message that the location information of the UE is unavailable to the AMF, and the AMF releases the UE. The situation where the RAN device cannot obtain the location information of the UE that meets the requirements may be: the UE does not report the latest location information, or the UE cannot obtain the latest location information, etc.

可选地，AMF在向RAN设备发送上述位置请求消息时启动定时器，若定时器超过T0+DT时刻还未接收到UE的位置信息，AMF确认位置验证失败，可选地，AMF可以保存该UE的验证失败原因为未获得UE的位置信息。可选地，AMF释放该UE。 Optionally, the AMF starts a timer when sending the above location request message to the RAN device. If the timer exceeds T0+DT and the UE's location information has not been received, the AMF confirms that the location verification has failed. Optionally, the AMF can save the verification failure reason of the UE as the failure to obtain the UE's location information. Optionally, the AMF releases the UE.

可选的，步骤S402～S408在步骤S400之前或之后执行，本申请不限定。例如针对步骤S402～S408在步骤S400之前，AMF向RAN设备发送位置请求消息，该位置请求消息用于请求RAN设备上报UE的位置信息。进一步的，该位置请求消息请求RAN设备从UE获得UE的位置之后，RAN设备向AMF上报UE的位置信息。进一步的，该位置请求消息还携带指示信息，指示RAN设备获得UE的位置变化超过一定门限之后，RAN设备向AMF上报UE的最新的位置信息。Optionally, steps S402 to S408 are performed before or after step S400, which is not limited by the present application. For example, for steps S402 to S408, before step S400, the AMF sends a location request message to the RAN device, and the location request message is used to request the RAN device to report the location information of the UE. Furthermore, after the location request message requests the RAN device to obtain the location of the UE from the UE, the RAN device reports the location information of the UE to the AMF. Furthermore, the location request message also carries indication information, indicating that after the RAN device obtains the location change of the UE exceeding a certain threshold, the RAN device reports the latest location information of the UE to the AMF.

其中，步骤S402～S408为可选的。Among them, steps S402 to S408 are optional.

步骤S410，LMF收到上述AMF发送的位置确认请求消息后执行对UE的定位，获得UE的定位结果。Step S410: After receiving the location confirmation request message sent by the AMF, the LMF performs positioning on the UE and obtains the positioning result of the UE.

具体地，LMF对UE进行定位的方法可以参照上述图10所述的方法100，此处不再赘述。LMF对UE进行定位的方法也可以采用其他方法，本申请并不限定。Specifically, the method for LMF to locate the UE may refer to the method 100 shown in FIG. 10 above, which will not be described in detail here. The method for LMF to locate the UE may also adopt other methods, which are not limited in this application.

可选地，AMF给LMF发送上述位置确认请求消息后启动定时器，如果定时器超时还未获得定位结果则判定UE位置验证失败。可选地，AMF可以保存该UE的验证失败原因为未获得UE的定位结果。可选地，AMF释放该UE。Optionally, the AMF starts a timer after sending the above-mentioned location confirmation request message to the LMF. If the positioning result is not obtained before the timer times out, it is determined that the UE location verification has failed. Optionally, the AMF can save the verification failure reason of the UE as the failure to obtain the positioning result of the UE. Optionally, the AMF releases the UE.

可选地，LMF在收到上述位置确认请求消息后启动定时器，如果定时器超时还未获得定位结果则发送指示信息给AMF，指示信息指示定位失败；AMF收到指示信息后判定UE位置验证失败。可选地，AMF可以保存该UE的验证失败原因为未获得UE的定位结果。可选地，AMF释放该UE。步骤S412，LMF将计算得到的UE的定位结果发送给AMF。Optionally, after receiving the above-mentioned location confirmation request message, LMF starts a timer. If the positioning result is not obtained before the timer times out, an indication message is sent to AMF, and the indication message indicates that the positioning fails. After receiving the indication message, AMF determines that the UE location verification has failed. Optionally, AMF can save the verification failure reason of the UE as the failure to obtain the positioning result of the UE. Optionally, AMF releases the UE. In step S412, LMF sends the calculated positioning result of the UE to AMF.

步骤S414，AMF根据LMF发送的UE的定位结果对RAN设备发送的UE的位置信息进行验证。示例性地，可以当RAN设备发送的UE的位置与LMF发送的UE的位置的距离小于阈值#A时，认为对UE的位置信息验证通过，否则不通过。其中，该阈值#A可以根据实际需要灵活设定，本申请对此不作限定。Step S414, AMF verifies the location information of the UE sent by the RAN device according to the positioning result of the UE sent by the LMF. Exemplarily, when the distance between the location of the UE sent by the RAN device and the location of the UE sent by the LMF is less than the threshold #A, it is considered that the location information of the UE is verified, otherwise it is not verified. Among them, the threshold #A can be flexibly set according to actual needs, and this application does not limit this.

可选地，步骤S412也可以是AMF将UE的位置信息发送给LMF，LMF根据UE的定位结果对UE的位置信息进行验证，并将验证结果返回给AMF。Optionally, step S412 may also be that the AMF sends the UE's location information to the LMF, and the LMF verifies the UE's location information based on the UE's positioning result and returns the verification result to the AMF.

对于位置验证失败的UE，AMF判断该UE不可信，AMF会触发UE去注册；对于连续多次位置验证都通过的UE，AMF认为该UE可信，并标记该UE可信。AMF可以在标记该UE可信后指示RAN设备该UE可信，或者AMF可以在UE从RRC空闲态(RRC_IDLE)或RRC非激活态(RRC_IN ACTIVE)进入RRC连接态(RRC_CONNECTED)时通知该UE接入的RAN设备该UE可信。UE上报位置信息可信的标记可以保存在AMF中，当该UE后续请求接入网络时，可以认为该UE仍然是可信的，直接允许其接入网络。For UEs that fail location verification, AMF determines that the UE is untrustworthy and triggers the UE to deregister. For UEs that pass location verification multiple times in a row, AMF considers the UE to be trustworthy and marks the UE as trustworthy. AMF can indicate to the RAN device that the UE is trustworthy after marking the UE as trustworthy, or AMF can notify the RAN device to which the UE is connected that the UE is trustworthy when the UE enters the RRC connected state (RRC_CONNECTED) from the RRC idle state (RRC_IDLE) or the RRC inactive state (RRC_IN ACTIVE). The mark that the UE reports location information as trustworthy can be saved in the AMF. When the UE subsequently requests to access the network, it can be considered that the UE is still trustworthy and is directly allowed to access the network.

通过上述方法400，可以使得对RAN设备上报的UE的位置信息进行验证时RAN设备上报的UE的位置信息有效，提升网络侧对UE的位置信息进行验证的可靠性。另外，可以使得RAN设备上报的UE的位置信息满足网络侧的验证精度要求，避免RAN设备上报的UE的位置精度太低导致的网络侧无法进行验证的问题。Through the above method 400, the location information of the UE reported by the RAN device can be made valid when the location information of the UE reported by the RAN device is verified, thereby improving the reliability of the network side's verification of the location information of the UE. In addition, the location information of the UE reported by the RAN device can meet the verification accuracy requirements of the network side, thereby avoiding the problem that the network side cannot perform verification due to the low location accuracy of the UE reported by the RAN device.

上述方法400是由AMF触发的验证，还可以通过RAN设备来触发验证，如图14所述的方法500。The above method 400 is a verification triggered by AMF, and verification can also be triggered by a RAN device, such as method 500 shown in Figure 14.

步骤S500，RAN设备触发对UE上报的位置信息的验证。Step S500: The RAN device triggers verification of location information reported by the UE.

若RAN设备处存在UE的位置信息，则RAN设备可以将UE的位置信息发送给AMF；可选地，若RAN设备处不存在UE的位置信息，步骤S500包括RAN设备向UE发送位置请求消息，该位置请求消息用于请求UE上报自身的位置信息。If the UE location information exists at the RAN device, the RAN device may send the UE location information to the AMF; optionally, if the UE location information does not exist at the RAN device, step S500 includes the RAN device sending a location request message to the UE, where the location request message is used to request the UE to report its own location information.

可选地，步骤S502，UE根据RAN设备发送的位置请求消息上报自身的位置信息。Optionally, in step S502, the UE reports its own location information according to a location request message sent by the RAN device.

步骤S504，RAN设备向AMF发送信息#1。Step S504, the RAN device sends information #1 to the AMF.

具体地，上述信息#1包括UE的位置信息、第二时段或者UE的位置信息对应的时间信息(例如，UE的位置信息的测量时间或基站获取UE的位置信息的时间)。Specifically, the above information #1 includes the location information of the UE, the second time period, or time information corresponding to the location information of the UE (for example, the measurement time of the location information of the UE or the time when the base station obtains the location information of the UE).

当上述信息#1包括第二时段时，RAN设备请求AMF在第二时段内对UE的位置信息进行验证。示例地，可以以RAN设备触发验证的时刻为参考时间，记为T1。第二时段可以为[T1，T2]。该T2时刻为AMF对UE的位置信息进行验证的最晚时刻。When the above information #1 includes the second time period, the RAN device requests the AMF to verify the location information of the UE within the second time period. For example, the time when the RAN device triggers the verification can be used as the reference time, recorded as T1. The second time period can be [T1, T2]. The T2 moment is the latest moment when the AMF verifies the location information of the UE.

当上述信息#1包括UE的位置信息对应的时间信息时，则AMF对以该时间信息中的时间为起点之后的一段时间DT内对UE的位置信息进行验证。该时间段DT的取值可以由AMF决定或协议中规定。When the above information #1 includes the time information corresponding to the location information of the UE, the AMF verifies the location information of the UE within a period of time DT starting from the time in the time information. The value of the time period DT can be determined by the AMF or specified in the protocol.

步骤S506，AMF向LMF发送位置确认请求消息，该位置确认请求消息用于请求LMF对UE进行定位。相应地，LMF接收AMF发送的该位置确认请求消息。Step S506: AMF sends a location confirmation request message to LMF, where the location confirmation request message is used to request LMF to locate the UE. Correspondingly, LMF receives the location confirmation request message sent by AMF.

步骤S508，LMF收到上述AMF发送的位置确认请求消息后执行对UE的定位，获得UE的定位结果。 Step S508: After receiving the location confirmation request message sent by the AMF, the LMF performs positioning on the UE and obtains the positioning result of the UE.

具体地，上述LMF的定位时间与UE的位置信息的测量时间或UE的位置信息的获取时间的间隔尽量短，时间间隔过长时UE可能发生移动，导致LMF对UE的定位结果与RAN设备上报的UE的位置信息差别太大。以及上述LMF的定位时间尽量避开卫星切换的时刻或临近卫星切换的时刻，避免卫星切换导致的测量结果不可用的情况发生。Specifically, the interval between the positioning time of the LMF and the measurement time of the UE's location information or the acquisition time of the UE's location information is as short as possible. If the time interval is too long, the UE may move, resulting in a large difference between the LMF's positioning result of the UE and the UE's location information reported by the RAN device. And the positioning time of the LMF should avoid the moment of satellite switching or the moment close to satellite switching as much as possible to avoid the situation where the measurement result is unavailable due to satellite switching.

步骤S510，LMF将计算得到的UE的定位结果发送给AMF。Step S510: LMF sends the calculated UE positioning result to AMF.

步骤S512，AMF根据LMF发送的UE的定位结果对RAN设备发送的UE的位置信息进行验证。示例性地，可以当RAN设备发送的UE的位置与LMF发送的UE的位置的距离小于阈值#B时，认为对UE的位置信息验证通过，否则不通过。其中，该阈值#B可以根据实际需要灵活设定，本申请对此不作限定。Step S512, AMF verifies the location information of the UE sent by the RAN device according to the positioning result of the UE sent by the LMF. Exemplarily, when the distance between the location of the UE sent by the RAN device and the location of the UE sent by the LMF is less than the threshold #B, it is considered that the location information of the UE is verified, otherwise it is not verified. Among them, the threshold #B can be flexibly set according to actual needs, and this application does not limit this.

可选地，步骤S512也可以是AMF将UE的位置信息发送给LMF，LMF根据UE的定位结果对UE的位置信息进行验证，并将验证结果返回给AMF。Optionally, step S512 may also be that the AMF sends the UE's location information to the LMF, and the LMF verifies the UE's location information based on the UE's positioning result and returns the verification result to the AMF.

通过上述方法500，可以使得AMF在对RAN设备上报的UE的位置信息进行验证时在限定的时间范围内执行验证，确保RAN设备上报的UE的位置信息有效，提升网络侧对UE的位置信息进行验证的可靠性。Through the above method 500, the AMF can perform verification within a limited time range when verifying the UE location information reported by the RAN device, thereby ensuring that the UE location information reported by the RAN device is valid and improving the reliability of the network side's verification of the UE location information.

如前所述，基于图9所示的多次测量的定位算法精度依赖于RTT的估计精度以及RTT的测量时间间隔，RTT的测量时间间隔越长，解算误差越小，定位精度越高。然而，过长的测量时间间隔会导致较长的验证时延。本申请提供一种方法600，既可以提升卫星定位精度，又可以满足UE位置的验证时延，如图15所示的方法600。方法600可以适用于上述方法200、上述方法300、上述方法400、上述方法500中LMF执行UE的定位测量的过程。As mentioned above, the accuracy of the positioning algorithm based on multiple measurements shown in Figure 9 depends on the estimation accuracy of RTT and the measurement time interval of RTT. The longer the measurement time interval of RTT, the smaller the solution error and the higher the positioning accuracy. However, too long a measurement time interval will result in a longer verification delay. The present application provides a method 600 that can both improve satellite positioning accuracy and meet the verification delay of UE location, as shown in method 600 in Figure 15. Method 600 can be applicable to the process of LMF performing UE positioning measurement in the above method 200, the above method 300, the above method 400, and the above method 500.

示例性地，下文以Multi-RTT定位方法为例描述方法600，但是适用于本申请技术方案的其它定位方法也在本申请的保护范围之内。Exemplarily, the method 600 is described below by taking the Multi-RTT positioning method as an example, but other positioning methods applicable to the technical solution of the present application are also within the protection scope of the present application.

步骤S600，RAN设备向LMF发送信息#2。该信息#2用于辅助LMF确定参考信号的配置信息。Step S600: The RAN device sends information #2 to the LMF. The information #2 is used to assist the LMF in determining configuration information of the reference signal.

示例性的，RAN设备向LMF发送信息#2时，RAN设备先将信息#2发送给AMF，AMF转发给LMF。Exemplarily, when the RAN device sends information #2 to the LMF, the RAN device first sends information #2 to the AMF, and the AMF forwards it to the LMF.

具体地，上述信息#2包括以下至少一种信息：Specifically, the above information #2 includes at least one of the following information:

RAN设备预期的UE位置的测量总时长、RAN设备预期的测量时间间隔、卫星状态信息、第四时刻等。其中，RAN设备预期的UE位置的测量总时长也可以是UE位置的验证总时长，RAN设备预期的UE位置的验证总时长与卫星的信息、验证精度要求等相关；RAN设备预期的测量时间间隔与卫星的移动速度、卫星的轨道高度以及UE位置的测量精度等相关；卫星的状态信息包括卫星切换的时刻、切换前后卫星的位置、切换前后卫星的移动速度等信息；上述第四时刻是为了给LMF提供定位参考时机，使定位能够在单星的服务周期内完成，避开卫星切换。或者，上述第四时刻是为了让LMF在临近卫星切换的时间不进行测量。The total measurement duration of the UE position expected by the RAN device, the measurement time interval expected by the RAN device, the satellite status information, the fourth moment, etc. Among them, the total measurement duration of the UE position expected by the RAN device can also be the total verification duration of the UE position. The total verification duration of the UE position expected by the RAN device is related to the satellite information, verification accuracy requirements, etc.; the measurement time interval expected by the RAN device is related to the moving speed of the satellite, the orbital height of the satellite, and the measurement accuracy of the UE position; the satellite status information includes the time of satellite switching, the position of the satellite before and after the switching, the moving speed of the satellite before and after the switching, etc.; the fourth moment is to provide LMF with a positioning reference opportunity so that positioning can be completed within the service cycle of a single satellite to avoid satellite switching. Alternatively, the fourth moment is to prevent LMF from performing measurements near the time of satellite switching.

具体地，上述卫星可以认为是NTN设备。Specifically, the above-mentioned satellites can be considered as NTN devices.

可选地，上述信息#2也可以是操作维护管理(operation administration and maintenance，OAM)提供给LMF的。Optionally, the above information #2 can also be provided to LMF by operation administration and maintenance (OAM).

RAN设备预期也可以称为RAN设备希望或RAN设备推荐。步骤S602，LMF根据上述信息#2确定参考信号的配置信息。可选的，LMF可以根据上述信息#2确定定位算法。RAN device expectation may also be referred to as RAN device hope or RAN device recommendation. Step S602, LMF determines configuration information of the reference signal according to the above information #2. Optionally, LMF may determine a positioning algorithm according to the above information #2.

具体地的，上述参考信号的配置信息包括以下至少一项：Specifically, the configuration information of the reference signal includes at least one of the following:

参考信号发送或接收的时刻、参考信号发送或接收的周期或参考信号发送或接收的时间间隔等。The time when the reference signal is sent or received, the period when the reference signal is sent or received, or the time interval when the reference signal is sent or received, etc.

步骤S604，LMF将RAN设备发送或接收的参考信号的配置信息发送给RAN设备。Step S604: The LMF sends the configuration information of the reference signal sent or received by the RAN device to the RAN device.

步骤S606，LMF将UE发送或接收的参考信号的配置信息发送给UE。Step S606: LMF sends the configuration information of the reference signal sent or received by the UE to the UE.

示例性的，LMF通过RAN设备向UE发送UE发送或接收的参考信号的配置信息。Exemplarily, the LMF sends configuration information of a reference signal sent or received by the UE to the UE through a RAN device.

其中，步骤S604和S606可能并不是同时存在，可能只存在其中一个步骤。Among them, steps S604 and S606 may not exist at the same time, and only one of the steps may exist.

步骤S608，LMF从RAN设备或/和UE获得测量结果，根据测量结果获得UE的定位结果。Step S608: LMF obtains measurement results from the RAN device and/or the UE, and obtains the positioning result of the UE according to the measurement results.

方法600的其它步骤可以参照上述方法400和方法500的其它步骤，此处不再赘述。The other steps of method 600 may refer to the other steps of the above-mentioned method 400 and method 500, and will not be described in detail here.

通过上述方法600，不仅可以提升卫星对UE的定位精度，而且可以满足UE位置的验证时延。Through the above method 600, not only the positioning accuracy of the satellite for the UE can be improved, but also the verification delay of the UE position can be met.

LEO卫星对UE进行定位过程中，单个卫星与UE的连接时间有限，在定位过程中有可能发生卫星切换。如果当前定位测量时发送参考信号的卫星和接收参考信号的卫星不是同一颗卫星，那么可能会导致当前定位测量的结果不可用。本申请提供一种解决卫星切换过程中测量结果不可用问题的方法700，如图16所示。During the LEO satellite positioning process, the connection time between a single satellite and the UE is limited, and satellite switching may occur during the positioning process.
