发明内容Contents of the invention
本申请提供一种定位方法、装置、存储介质及芯片***,用于对处于RRC空闲态的终端设备进行定位。This application provides a positioning method, device, storage medium and chip system for positioning terminal equipment in RRC idle state.
第一方面,本申请实施例提供一种定位方法,该方法可以由终端设备执行,也可以由终端设备内部的单元、模块或芯片执行,本申请中以该终端设备侧的方法由终端设备为例进行介绍。该方法包括:In the first aspect, embodiments of the present application provide a positioning method, which can be executed by a terminal device or by a unit, module or chip inside the terminal device. In this application, the method on the terminal device side is performed by the terminal device. Examples are introduced. The method includes:
处于RRC空闲态的终端设备向核心网网元发送第一信息,第一信息用于请求定位服务,第一信息包括第一资源指示信息,第一资源指示信息用于确定目标参考信号资源。处于RRC空闲态的终端设备接收来自核心网网元的第二信息,第二信息是基于第一资源指示信息得到的。处于RRC空闲态的终端设备基于第二信息得到目标参考信号资源。处于RRC空闲态的终端设备根据目标参考信号资源发送参考信号,参考信号用于确定终端设备的位置。The terminal device in the RRC idle state sends first information to the core network element. The first information is used to request positioning services. The first information includes first resource indication information. The first resource indication information is used to determine target reference signal resources. The terminal device in the RRC idle state receives second information from the core network element, where the second information is obtained based on the first resource indication information. The terminal device in the RRC idle state obtains the target reference signal resource based on the second information. The terminal device in the RRC idle state sends a reference signal according to the target reference signal resource, and the reference signal is used to determine the location of the terminal device.
由于处于RRC空闲态的终端设备可以与移动性管理网元建立NAS接口上的安全,但是不会与接入网设备建立空口上的连接和空口安全,因此接入网设备并不会知道终端设备当前所处的位置,也不清楚适合终端设备使用的参考信号资源有哪些。由于终端设备可以向核心网网元发送用于请求定位服务的第一信息,第一信息包括第一资源指示信息,又由于终端设备可以从核心网网网元接收第二信息,第二信息基于第一资源指示信息得到,且
终端设备可以根据第二信息确定出目标参考信号资源,从而处于RRC空闲态的终端设备可以根据该目标参考信号资源发送参考信号,以便实现对处于RRC空闲态的终端设备的定位。且该过程中终端设备不会与接入网设备建立空口上的连接和空口安全,可以一直处于RRC空闲态,无需进入RRC连接态,也无需进入RRC非激活态,从而可以降低终端设备的功耗,也可以降低对终端设备进行定位的时延。Since the terminal device in the RRC idle state can establish security on the NAS interface with the mobility management network element, it will not establish air interface connection and air interface security with the access network device, so the access network device will not know about the terminal device. At the current location, it is not clear what reference signal resources are suitable for terminal equipment. Because the terminal device can send the first information for requesting the positioning service to the core network element, the first information includes the first resource indication information, and because the terminal device can receive the second information from the core network element, the second information is based on The first resource indication information is obtained, and The terminal device can determine the target reference signal resource according to the second information, so that the terminal device in the RRC idle state can send the reference signal according to the target reference signal resource to achieve positioning of the terminal device in the RRC idle state. And during this process, the terminal device will not establish an air interface connection and air interface security with the access network device. It can always be in the RRC idle state without entering the RRC connected state or the RRC inactive state, which can reduce the performance of the terminal device. It consumes less energy and can also reduce the delay in locating the terminal device.
在一种可能的实施方式中,第二信息包括第一时长的信息。这种情况下,处于RRC空闲态的终端设备可以在第一时长之后,根据目标参考信号资源发送参考信号。如此,接入网设备可以配置终端设备发送参考信号的时间,从而可以增加对终端设备的可控性。In a possible implementation, the second information includes information of the first duration. In this case, the terminal device in the RRC idle state may send the reference signal according to the target reference signal resource after the first duration. In this way, the access network device can configure the time at which the terminal device sends the reference signal, thereby increasing the controllability of the terminal device.
在一种可能的实施方式中,第一资源指示信息包括以下内容中的至少一项:终端设备的位置对应的小区的信息;终端设备对接收到的信号进行无线资源管理(radio resource management,RRM)测量的结果;终端设备对接收到的定位参考信号(positioning reference signal,PRS)测量的结果;终端设备的位置信息;或,第一参考信号资源的信息。接入网设备并不会知道终端设备当前所处的位置,因此也不清楚适合终端设备使用的参考信号资源有哪些,通过上述实施方式,接入网设备可以根据处于RRC空闲态的终端设备的位置对应的小区的信息、RRM测量的结果、PRS测量的结果、位置信息或第一参考信号资源的信息中的至少一项确定出终端设备适用的参考信号资源,继而可以从终端设备适用的参考信号资源中为处于RRC空闲态的终端设备分配参考信号资源。In a possible implementation, the first resource indication information includes at least one of the following: information about the cell corresponding to the location of the terminal device; radio resource management (RRM) performed by the terminal device on the received signal. ) measurement results; the measurement results of the positioning reference signal (PRS) received by the terminal device; the location information of the terminal device; or the information of the first reference signal resource. The access network equipment does not know the current location of the terminal equipment, so it does not know what reference signal resources are suitable for the terminal equipment. Through the above implementation, the access network equipment can be based on the terminal equipment in the RRC idle state. At least one of the information of the cell corresponding to the location, the result of RRM measurement, the result of PRS measurement, the location information or the information of the first reference signal resource determines the reference signal resource applicable to the terminal equipment, and then the reference signal resource applicable to the terminal equipment can be determined. In the signal resources, reference signal resources are allocated to the terminal equipment in the RRC idle state.
在一种可能的实施方式中,处于RRC空闲态的终端设备发送第一信息之前,处于RRC空闲态的终端设备在预设的触发终端设备请求定位服务的事件被满足的情况下,接收来自接入网设备的***消息,***消息包括参考信号配置信息,目标参考信号资源为参考信号配置信息中的资源。在预设的触发终端设备请求定位服务的事件未被满足的情况下,处于RRC空闲态的终端设备可以不接收***消息,从而可以降低终端设备的功耗。In a possible implementation, before the terminal device in the RRC idle state sends the first information, the terminal device in the RRC idle state receives an incoming call when a preset event that triggers the terminal device to request positioning service is met. System messages of network access equipment. The system messages include reference signal configuration information. The target reference signal resources are the resources in the reference signal configuration information. When the preset event that triggers the terminal device to request positioning services is not met, the terminal device in the RRC idle state may not receive system messages, thereby reducing the power consumption of the terminal device.
在一种可能的实施方式中,处于RRC空闲态的终端设备接收来自接入网设备的***消息之后,处于RRC空闲态的终端设备发送第一信息之前,终端设备根据对接收到的信号的测量结果,从***消息包括的参考信号配置信息中确定第一资源指示信息中的第一参考信号资源的信息。参考信号配置信息中可以预先配置信号的测量结果和参考信号资源的关联关系,终端设备可以从该关联关系中查找出信号的测量结果对应的参考信号资源,继而从该对应的参考信号资源中确定出第一参考信号资源,如此,终端设备可以从自己可以用的参考信号资源中找出自己想要的第一参考信号资源,继而可以将该第一参考信号资源发送给核心网设备,以使核心网设备将第一参考信号资源发送给接入网设备,以便接入网设备考虑是否将第一参考信号资源分配给该终端设备。In a possible implementation, after the terminal device in the RRC idle state receives the system message from the access network device and before the terminal device in the RRC idle state sends the first information, the terminal device measures the received signal according to As a result, the information of the first reference signal resource in the first resource indication information is determined from the reference signal configuration information included in the system message. The reference signal configuration information can be pre-configured with an association between the signal measurement results and the reference signal resources. The terminal device can find out the reference signal resources corresponding to the signal measurement results from the association, and then determine the reference signal resources from the corresponding reference signal resources. In this way, the terminal device can find out the first reference signal resource it wants from the reference signal resources available to it, and then can send the first reference signal resource to the core network device so that The core network device sends the first reference signal resource to the access network device, so that the access network device considers whether to allocate the first reference signal resource to the terminal device.
在一种可能的实施方式中,第二信息包括第二资源指示信息,第二资源指示信息是根据第一资源指示信息确定的。处于RRC空闲态的终端设备根据第二资源指示信息确定目标参考信号资源。由于第二信息包括第二资源指示信息,即接入网设备基于第一资源指示信息确定出第二资源指示信息,因此终端设备可以根据第二资源指示信息确定出接入网设备为终端设备分配的目标参考信号资源。In a possible implementation, the second information includes second resource indication information, and the second resource indication information is determined based on the first resource indication information. The terminal equipment in the RRC idle state determines the target reference signal resource according to the second resource indication information. Since the second information includes the second resource indication information, that is, the access network device determines the second resource indication information based on the first resource indication information, the terminal device can determine, based on the second resource indication information, that the access network device allocates the resource to the terminal device. target reference signal resources.
第二资源指示信息包括目标参考信号资源或一个或多个小区信息。当第二资源指示信息包括一个或多个小区信息,处于RRC空闲态的终端设备可以从参考信号配置信息中查找出第一资源指示信息中包括的小区信息所关联的参考信号资源,并将该参考信号资源确定为目标参考信号资源。
The second resource indication information includes target reference signal resources or one or more cell information. When the second resource indication information includes one or more cell information, the terminal device in the RRC idle state can find the reference signal resource associated with the cell information included in the first resource indication information from the reference signal configuration information, and use the The reference signal resource is determined as the target reference signal resource.
一种可能的实施方式中,接入网设备允许基于第一资源指示信息得到目标参考信号资源,这种情况下,当处于RRC空闲态的终端设备基于第二信息,确定接入网设备允许基于第一资源指示信息得到目标参考信号资源,则终端设备根据第一资源指示信息确定目标参考信号资源。比如,在第一资源指示信息包括第一参考信号资源的信息的情况下,终端设备确定第一参考信号资源为目标参考信号资源。In a possible implementation, the access network device is allowed to obtain target reference signal resources based on the first resource indication information. In this case, when the terminal device in the RRC idle state determines that the access network device is allowed to obtain the target reference signal resource based on the second information. After obtaining the target reference signal resource from the first resource indication information, the terminal device determines the target reference signal resource according to the first resource indication information. For example, in the case where the first resource indication information includes information about the first reference signal resource, the terminal device determines that the first reference signal resource is the target reference signal resource.
当接入网设备允许基于第一资源指示信息得到目标参考信号资源的情况下,第二信息中可以包括第一资源指示信息,也可以不包括第一资源指示信息。比如,处于RRC空闲态的终端设备在确定第二信息中未包括用于指示参考信号资源的信息情况下,确定接入网设备允许基于第一资源指示信息得到参考信号资源。可以看出,当接入网设备允许基于第一资源指示信息得到目标参考信号资源的情况下,接入网设备发送的第二信息中可以不包括用于指示参考信号资源的信息,如此,可以减少第二信息所承载的数据量,节省资源,加快数据传输速度。When the access network device allows the target reference signal resource to be obtained based on the first resource indication information, the second information may or may not include the first resource indication information. For example, when the terminal device in the RRC idle state determines that the second information does not include information indicating reference signal resources, it determines that the access network device allows the reference signal resources to be obtained based on the first resource indication information. It can be seen that when the access network device allows the target reference signal resource to be obtained based on the first resource indication information, the second information sent by the access network device may not include information for indicating the reference signal resource. In this way, it may Reduce the amount of data carried by the second information, save resources, and speed up data transmission.
在一种可能的实施方式中,第一信息包括用于请求定位服务的信息。如此,核心网设备可以根据用于请求定位服务的信息确定终端设备需要请求定位服务。In a possible implementation, the first information includes information used to request positioning services. In this way, the core network device can determine that the terminal device needs to request the positioning service based on the information used to request the positioning service.
在一种可能的实施方式中,第一信息承载于NAS消息中的控制面服务请求消息,用于请求定位服务的信息包括:控制面服务请求消息中用于指示控制面服务类型为定位服务类型的信息。如此,可以更好的与现有技术兼容。In a possible implementation, the first information is carried in a control plane service request message in the NAS message, and the information used to request the positioning service includes: the control plane service request message is used to indicate that the control plane service type is a positioning service type. Information. In this way, it can be better compatible with existing technologies.
第一信息也可以承载于NAS消息容器中的NAS消息中的LCS消息中,LCS消息比如可以包括事件报告消息,事件报告消息中可以包括触发终端设备请求定位服务的事件的信息。触发终端设备请求定位服务的事件的信息可以视为第一信息中用于请求定位服务的信息。The first information may also be carried in an LCS message in a NAS message in a NAS message container. For example, the LCS message may include an event report message, and the event report message may include information about an event that triggers the terminal device to request positioning service. The information of the event that triggers the terminal device to request the positioning service may be regarded as the information in the first information used to request the positioning service.
在一种可能的实施方式中,核心网网元为移动性管理网元的情况下,处于RRC空闲态的终端设备接收来自核心网网元的第二信息之前,处于RRC空闲态的终端设备向核心网网元发送用于为终端设备提供定位服务的位置管理功能网元的标识。如此,核心网设备可以根据位置管理功能网元的标识确定出位置管理功能网元,从而可以节省查找位置管理功能网元所花费的时间,进而可以降低终端设备定位的时延。In a possible implementation, when the core network element is a mobility management network element, before the terminal device in the RRC idle state receives the second information from the core network element, the terminal device in the RRC idle state sends a message to the mobility management network element. The core network element sends the identity of the location management function network element used to provide positioning services for the terminal device. In this way, the core network equipment can determine the location management function network element according to the identity of the location management function network element, thereby saving the time spent in searching for the location management function network element, thereby reducing the terminal device positioning delay.
在一种可能的实施方式中,核心网网元为移动性管理网元。第一信息和第二信息满足以下内容中的一项:第一信息承载于四步随机接入过程中的消息三中的非接入网层(non-access stratum,NAS)消息容器,第二信息承载于四步随机接入过程中的消息四中的NAS消息容器;第一信息承载于二步随机接入过程中的消息A中的NAS消息容器,第二信息承载于二步随机接入过程中的消息B中的NAS消息容器;第一信息承载于授予小配置数据传输(configured grant small data transmission,CG-SDT)中的NAS消息容器,第二信息承载于CG-SDT的响应消息中的NAS消息容器;第一信息承载于预先配置上行链路资源(pre-configured uplink resource,PUR)中的NAS消息容器,第二信息承载于PUR的响应消息中的NAS消息容器;或,第一信息承载于早期数据传输(early data transmission,EDT)中的NAS消息容器,第二信息承载于EDT的响应消息中的NAS消息容器。如此可以兼容现有技术。In a possible implementation manner, the core network element is a mobility management network element.

由于处于RRC空闲态的终端设备可以与移动性管理网元建立NAS接口上的安全,但是不会与接入网设备建立空口上的连接和空口安全,因此接入网设备并不会知道终端设备当前所处的位置,也不清楚适合终端设备使用的参考信号资源有哪些。而终端设备向位置管理功能网元发送(比如可以通过移动性管理网元向位置管理功能网元发送)的第一信息可以包括第一资源指示信息,第一资源指示信息用于确定目标参考信号资源。如此,位置管理功能网元可以将第一资源指示信息转给接入网设备,以便接入网设备为处于RRC空闲态的终端设备确定目标参考信号资源,从而终端设备根据该目标参考信号资源发送参考信号,以便实现对处于RRC空闲态的终端设备的定位。且该过程中终端设备不会与接入网设备建立空口上的连接和空口安全,可以一直处于RRC空闲态,无需进入RRC连接态,也无需进入RRC非激活态,从而可以降低终端设备的功耗,也可以降低对终端设备进行定位的时延,降低终端设备的成本。Since the terminal device in the RRC idle state can establish security on the NAS interface with the mobility management network element, it will not establish air interface connection and air interface security with the access network device, so the access network device will not know about the terminal device.

由于第二信息包括第二资源指示信息,即接入网设备基于第一资源指示信息确定出第二资源指示信息,因此终端设备可以根据第二资源指示信息确定出接入网设备为终端设备分配的目标参考信号资源。Since the second information includes the second resource indication information, that is, the access network device determines the second resource indication information based on the first resource indication information, the terminal device can determine, based on the second resource indication information, that the access network device allocates the resource to the terminal device. target reference signal resources.

当接入网设备允许基于第一资源指示信息得到目标参考信号资源的情况下,第二信息中可以包括第一资源指示信息,也可以不包括第一资源指示信息。比如,位置管理功能网元在确定第二信息中未包括用于指示参考信号资源的信息情况下,确定接入网设备允许基于第一资源指示信息得到参考信号资源。可以看出,当接入网设备允许基于第一资源指示信息得到目标参考信号资源的情况下,接入网设备发送的第二信息中可以不包括用于指示参考信号资源的信息,如此,可以减少第二信息所承载的数据量,节省资源,加快数据传输速度。When the access network device allows the target reference signal resource to be obtained based on the first resource indication information, the second information may or may not include the first resource indication information. For example, when the location management function network element determines that the second information does not include information for indicating reference signal resources, it determines that the access network device allows the reference signal resources to be obtained based on the first resource indication information. It can be seen that when the access network device allows the target reference signal resource to be obtained based on the first resource indication information, the second information sent by the access network device may not include information for indicating the reference signal resource. In this way, it may Reduce the amount of data carried by the second information, save resources, and speed up data transmission.

The information of the first reference signal resource may include information that can indicate the first reference signal resource, such as an index and an identifier of the first reference signal resource.

In a possible implementation, before step 201, the terminal device in the RRC idle state can receive a system message from the access network device when a preset event that triggers the terminal device to request positioning services is met. System messages include reference signal configuration information. It can also be understood that the terminal device in the RRC idle state does not need to receive system messages. When the terminal device determines that the preset event that triggers the terminal device to request positioning services is met, the terminal device receives the system message, which can save more power consumption. .
触发终端设备请求定位服务的事件可以是预设的一个或多个事件。比如该事件可以包括:终端设备周期性请求定位服务,这种情况下,当周期时长到达后,终端设备可以确定该事件被满足。再比如,该事件可以包括:终端设备移出小区的覆盖范围则请求定位服务,这种情况下,当终端设备移出当前小区的覆盖范围,终端设备确定该事件被满足。The event that triggers the terminal device to request location services may be one or more preset events. For example, the event may include: the terminal device periodically requests positioning services. In this case, when the period duration is reached, the terminal device may determine that the event is satisfied. For another example, the event may include: the terminal device requests positioning service when it moves out of the coverage of the cell. In this case, when the terminal device moves out of the coverage of the current cell, the terminal device determines that the event is satisfied.

For example, the LMF may carry the second information in the LCS message, and send the LCS message carrying the second information to the terminal device through other network elements (such as AMF, access network equipment, etc.). For another example, the LMF can carry the second information in the LCS message and send the LCS message to the AMF. Then the AMF carries the second information in the NAS message and transmits it through other network elements (such as access network equipment, etc.) The NAS message carrying the second information is sent to the terminal device.

实施方式B1,第二信息包括第二资源指示信息,第二资源指示信息是根据第一资源指示信息确定的。In embodiment B1, the second information includes second resource indication information, and the second resource indication information is determined based on the first resource indication information.
在步骤205中,处于RRC空闲态的终端设备可以根据第二资源指示信息确定目标参考信号资源。In step 205, the terminal device in the RRC idle state may determine the target reference signal resource according to the second resource indication information.
比如,第二资源指示信息包括目标参考信号资源,则终端设备可以从第二信息中确定出目标参考信号资源。For example, if the second resource indication information includes the target reference signal resource, the terminal device can determine the target reference signal resource from the second information.
再比如,第二资源指示信息包括一个或多个小区的信息,比如第二资源指示信息包括一个或多个小区的标识、索引等信息。第二资源指示信息中的小区的信息可以为小区列表,为了区分,本申请实施例中将第二资源指示信息中的小区列表称为第二小区列表。这种情况下,终端设备可以根据第二信息包括的小区的信息(比如第二小区列表)确定目标参考信号资源。举个例子,参考信号配置信息中可以包括用于确定目标参考信号资源的信息(比如小区列表)与资源的关联关系,终端设备可以根据第二信息中的第二小区列表,从参考信号配置信息中查找出与第二小区列表关联的参考信号资源,并将该参考信号资源确定为目标参考信号资源。终端设备获取参考信号配置信息的方式可以参见前述内容,不再赘述。For another example, the second resource indication information includes information of one or more cells. For example, the second resource indication information includes information such as identifiers and indexes of one or more cells. The cell information in the second resource indication information may be a cell list. For distinction, in the embodiment of this application, the cell list in the second resource indication information is called the second cell list. In this case, the terminal device may determine the target reference signal resource according to the cell information (such as the second cell list) included in the second information. For example, the reference signal configuration information may include information used to determine the target reference signal resource (such as a cell list) and the association relationship between the resources. The terminal device may configure the information from the reference signal according to the second cell list in the second information. Find the reference signal resource associated with the second cell list, and determine the reference signal resource as the target reference signal resource.

处于RRC空闲态的终端设备可以基于第二信息,确定接入网设备是否允许基于第一资源指示信息得到目标参考信号资源。The terminal device in the RRC idle state may determine, based on the second information, whether the access network device allows the target reference signal resource to be obtained based on the first resource indication information.
当接入网设备允许基于第一资源指示信息得到目标参考信号资源的情况下,第二信息中可以包括第一资源指示信息,也可以不包括第一资源指示信息。第二信息可以隐式指示接入网设备允许基于第一资源指示信息得到目标参考信号资源。比如,处于RRC空闲态的终端设备在确定第二信息中未包括用于指示参考信号资源的信息情况下,确定接入网设备允许基于第一资源指示信息得到参考信号资源。也可以理解为:处于RRC空闲态的终端设备在确定第二信息中未包括参考信号资源的信息,也未包括用于确定参考信号资源的信息(比如小区的信息(第二小区列表))的情况下,确定接入网设备允许基于第一资源指示信息得到参考信号资源。When the access network device allows the target reference signal resource to be obtained based on the first resource indication information, the second information may or may not include the first resource indication information. The second information may implicitly instruct the access network device to allow the target reference signal resource to be obtained based on the first resource indication information. For example, when the terminal device in the RRC idle state determines that the second information does not include information indicating reference signal resources, it determines that the access network device allows the reference signal resources to be obtained based on the first resource indication information. It can also be understood that: the terminal equipment in the RRC idle state determines that the second information does not include information about the reference signal resources, nor does it include information used to determine the reference signal resources (such as cell information (second cell list)). In this case, it is determined that the access network device allows the reference signal resource to be obtained based on the first resource indication information.
又一种可能的实施方式中,第二信息中也可以携带用于指示接入网设备允许基于第一资源指示信息得到目标参考信号资源的信息。这种情况下,终端设备根据该用于指示接入网设备允许基于第一资源指示信息得到目标参考信号资源的信息,确定接入网设备允许基于第一资源指示信息得到目标参考信号资源。In another possible implementation, the second information may also carry information used to instruct the access network device to allow the target reference signal resource to be obtained based on the first resource indication information. In this case, the terminal device determines that the access network device allows the access network device to obtain the target reference signal resource based on the first resource indication information based on the information used to instruct the access network device to allow the target reference signal resource to be obtained based on the first resource indication information.
当第一资源指示信息包括第一参考信号资源的信息的情况下,终端设备确定第一参考信号资源为目标参考信号资源。When the first resource indication information includes information about the first reference signal resource, the terminal device determines the first reference signal resource as the target reference signal resource.
当第一资源指示信息包括其它用于确定目标参考信号资源的信息(比如上述信息A1、信息A2、信息A3或信息A4中的至少一项),参考信号配置信息中可以包括用于确定目标参考信号资源的信息与参考信号资源的关联关系,终端设备可以根据第一资源指示信息中的用于确定目标参考信号资源的信息,从参考信号配置信息中查找出与该用于确定目标参考信号资源的信息关联的参考信号资源,并将该参考信号资源确定为目标参考信号资源。When the first resource indication information includes other information used to determine the target reference signal resource (such as at least one of the above-mentioned information A1, information A2, information A3, or information A4), the reference signal configuration information may include information used to determine the target reference signal resource. Regarding the relationship between the signal resource information and the reference signal resource, the terminal device can find out from the reference signal configuration information the information used to determine the target reference signal resource according to the information used to determine the target reference signal resource in the first resource indication information. the reference signal resource associated with the information, and determine the reference signal resource as the target reference signal resource.

一种可能的实施方式中,第二信息包括第一时长的信息,在步骤206中,处于RRC空闲态的终端设备在第一时长之后,根据目标参考信号资源发送参考信号。本申请实施例中终端设备发送的参考信号可以为信道探测参考信号(sounding reference signal,SRS)。In a possible implementation, the second information includes information of the first duration. In step 206, the terminal device in the RRC idle state sends the reference signal according to the target reference signal resource after the first duration. In this embodiment of the present application, the reference signal sent by the terminal device may be a channel sounding reference signal (sounding reference signal, SRS).
由于处于RRC空闲态的终端设备可以与AMF建立NAS接口上的安全,但是不会与接入网设备建立空口上的连接和空口安全,空口安全指的是RRC层的加密和完整性保护。因此接入网设备并不会知道终端设备当前所处的位置,也不清楚适合终端设备使用的参考信号资源有哪些。而终端设备向LMF发送(比如可以通过AMF向LMF发送)的第一信息可以包括第一资源指示信息,第一资源指示信息用于确定目标参考信号资源。如此,LMF可以将第一资源指示信息转给接入网设备,以便接入网设备为处于RRC空闲态的终端设备确定目标参考信号资源,从而终端设备根据该目标参考信号资源发送参考信号,以便实现对处于RRC空闲态的终端设备的定位。且该过程中终端设备不会与接入网设备建立空口上的连接和空口安全,可以一直处于RRC空闲态,无需进入RRC连接态,也无需进入RRC非激活态,从而可以降低终端设备的功耗,也可以降低对终端设备进行定位的时延。另一方面,该方案可以实现对处于RRC空闲态的终端设备的定位服务,可以不必要求终端设备支持RRC非激活态,从而可以降低对终端设备的能力要求,继而可以降低终端设备的成本。Since the terminal device in the RRC idle state can establish security on the NAS interface with the AMF, it will not establish an air interface connection and air interface security with the access network device. Air interface security refers to the encryption and integrity protection of the RRC layer. Therefore, the access network equipment does not know the current location of the terminal equipment, nor does it know what reference signal resources are suitable for the terminal equipment to use. The first information sent by the terminal device to the LMF (for example, may be sent to the LMF through the AMF) may include first resource indication information, and the first resource indication information is used to determine the target reference signal resource. In this way, the LMF can transfer the first resource indication information to the access network device, so that the access network device determines the target reference signal resource for the terminal device in the RRC idle state, so that the terminal device sends the reference signal according to the target reference signal resource, so that Realize the positioning of terminal equipment in RRC idle state. And during this process, the terminal device will not establish an air interface connection and air interface security with the access network device. It can always be in the RRC idle state without entering the RRC connected state or the RRC inactive state, which can reduce the performance of the terminal device. It consumes less energy and can also reduce the delay in locating the terminal device. On the other hand, this solution can realize positioning services for terminal equipment in the RRC idle state without requiring the terminal equipment to support the RRC inactive state, thereby reducing the capability requirements for the terminal equipment and thereby reducing the cost of the terminal equipment.
值得说明的是,在上述步骤204之后,又一种可能的实施方式中,终端设备不再执行
步骤205和步骤206。第二信息包括第二时长的信息。处于RRC空闲态的终端设备在第二时长之后,向核心网网元发送用于请求定位服务的信息。在该实施例中,接入网设备可以通过第二信息指示终端设备不再进行此次定位服务,而是自接收到第二信息的时刻起始,第二时长之后重新请求定位服务,比如可以重新执行上述步骤201以便向LMF发送更新后的第一资源指示信息。It is worth noting that after the above step 204, in another possible implementation, the terminal device no longer executes Step 205 and step 206. The second information includes information of a second duration. After the second period of time, the terminal device in the RRC idle state sends information for requesting positioning services to the core network element. In this embodiment, the access network device can instruct the terminal device through the second information not to perform the positioning service this time, but to re-request the positioning service after the second time period starting from the time when the second information is received. For example, Execute the above step 201 again to send the updated first resource indication information to the LMF.
