- the request can also carry preferred QoS class. It should be noted that if NWDAF If the consumer carries this information, it can be directly mapped to the QoS class of LCS in step 2. If it does not carry it, it needs to be mapped in step 2.
- Step 2 After receiving the above request, the NWDAF network element sends a message requesting positioning information to the LCS server.
- the message contains: positioning accuracy, QoS type and other information.
- the LCS server implements positioning accuracy requirements and QoS requirements during the positioning process with the target MS, which is the accuracy in LCS QoS, including horizontal accuracy (Horizontal accuracy), vertical accuracy (Vertical accuracy), and QoS types. .
- Step 4 The positioning accuracy and LCS QoS achieved during the positioning process are reported to the LCS server through LCS signaling in this step.
- Step 5 The LCS server reports the achieved positioning accuracy and QoS class to the NWDAF network element.
- the positioning delay, user privacy verification and other information can be provided to the NWDAF network element.
- Step 6 After receiving the implemented positioning accuracy and QoS class, if the requirements in step 1 can be met, then the NWDAF network element will reversely map this information to the implemented granularity and result credibility. The NWDAF network element will calculate the statistical results or This information is reported to the NWDAF consumer in the prediction message.
- the implemented positioning accuracy is mapped to the implemented granularity indication, and the reverse mapping is performed according to step 2;
- the type of QoS implemented is one of the calculation factors for the credibility of the result.
- the method of considering the credibility of the result is as follows:
- the NWDAF network element checks whether the implemented QoS class is consistent with the requirement. When other factors are consistent, if the implemented QoS class meets the requirements, the credibility of the result will be higher than if it is not implemented or does not meet the requirements;
- step 2 If the preferred QoS class is not provided in step 1, then according to the mapping relationship between the preferred analysis accuracy and the QoS class in step 2, compare the implemented QoS class with the mapped QoS class. When other factors are consistent, if the QoS class implemented meets the requirements, the credibility of the result will be higher than if the QoS class is not implemented or does not meet the requirements.
- the NWDAF network element determines the QoS, delay information, privacy verification and other information replied by the LCS server, and reports the relevant reasons to the NWDAF consumer.
- the reasons here include: link Long delays, user privacy verification failure, etc.
- the prerequisite for the NWDAF network element to send a request to the LCS server and the LCS server to send a request to the Target MS is that the user's privacy verification or the user's willingness check has passed.

下面先对与本申请相关的背景技术进行简要说明如下。
1、定位服务(LoCation Service,LCS)
LCS是核心网中由AMF和位置管理功能(Location Management Function,LMF)等网元负责执行并提供的。LCS消息在UE和LCS客户端(client)或者应用功能(Application Function,AF)之间交互,一个比较典型的流程就是终端终止定位请求(Mobile Terminated Location Request,MT-LR)。
MT-LR流程由外部第三方应用(LCS client)或者由AF经由NEF网元发起,经由网关移动定位中心(Gateway Mobile Location Centre,GMLC)、AMF、LMF等网元,最终获取到UE的位置信息。
其中LCS流程中,使用LCS服务质量(Quality of Service,QoS)参数集来表示整个LCS服务的水平,LCS QoS包括:
LCS QoS class(QoS类别);
精度(Accuracy,包括水平和垂直定位精度);
时延信息(Latency)。
2、网络数据分析功能(Network Data Analytics Function,NWDAF)
NWDAF是一种网络数据分析功能网元,支持搜集网元或者终端相关数据,提供统计和预测等信息。NWDAF可以从AMF、SMF等网元或者操作维护管理(Operation Administration and Maintenance,OAM)采集数据。现在流程中NWDAF获取终端的位置
信息是通过AMF搜集,终端位置信息是粗粒度,跟踪区(TrackingArea,TA)或者小区(cell)级别,即NWDAF能从AMF知道终端目前在哪个小区或者TA下。
如果NWDAF用户(consumer)向NWDAF发起服务请求,请求NWDAF统计相关的信息或者给出预测,那么NWDAF会根据请求消息中的参数去向不同的网元搜集信息,在NWDAF进行统计和分析之后,返回结果给NWDAF consumer。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的信息传输方法及网元进行详细地说明。

步骤24,所述第一核心网网元接收所述第一网元发送的终端的定位信息;
需要说明的是,因现有的定位服务只能提供粗粒度的定位服务,粗粒度的定位信息可以理解为定位精度为国家/地区精度以及TA或者cell精度的定位信息,而本申请中通过在NWDAF用户发送的定位服务请求中携带带有梯度的定位粒度,以此针对定位粒度进行定位信息的获取,以此保证能获取相应定位粒度的定位信息,保证第一核心网网元能够获取更精准的定位信息。
需要说明的是,本申请实施例的定位信息包括:
A11、终端的地理位置信息;
需要说明的是,该地理位置信息可以分为绝对位置坐标和相对位置坐标。

A22、民用场所(Civil location);
需要说明的是,该Civil location用于区域监管要求的紧急服务场景。
A23、时延;
需要说明的是,该时延指的是定位服务的时延信息。
A24、QoS种类;
需要说明的是,这里的QoS种类通常指的是感兴趣的QoS种类(即preferred QoS class),该QoS种类分为高级别QoS、中等级别QoS和低级别QoS。
需要说明的是,该高级别QoS指的是确定性QoS,即需要严格按照请求的定位信息的粒度进行统计和预测;该中等级别QoS指的是多重QoS,即优先执行请求的粒度,如果无法满足,则需满足次粒度要求;该低级别QoS指的是尽力而为QoS,即尽力实现定位流程,精度可以不作为强制要求。
A25、定位信息的生存周期(age of location)。
可选地,所述定位信息还可以包括:位置环境指示信息。
可选地,该位置环境指示信息,用于指示以下至少一项:
终端位于地面;
终端位于地下;

可选地,所述第一核心网网元根据所述定位服务请求,确定定位精度的方式,包括:
所述第一核心网网元将所述定位粒度指示信息所指示的定位粒度进行映射,获取定位精度。
例如,定位服务请求中的定位粒度指示的是定位范围大小,比如,定位服务请求中携带的定位粒度为10km,或者可以为100-1000m。
可选地,本申请实施例中提供的一种可选地映射方式为:
0表示需要的定位信息对应国家/地区精度(>10km);

需要说明的是,本申请实施例中将定位精度为国家/地区精度以及TA或者cell精度的定位信息看作为粗粒度定位信息,将小于TA或者cell精度的定位信息看作为细粒度定位信息。
需要说明的是,上述的映射方式是用不同的比特取值表示映射得到的不同的定位精度。
可选地,第二核心网网元还可以提供一个精度要求。然后由第一核心网网元根据实际情况来确定一个数值给第一网元。具体可以采用如下实施方式中的一种:
实施方式一、第二核心网网元希望获取终端精度在100m左右,即第二核心网网元告知第一核心网网元精度是[80m-120m],第一核心网网元根据自身情况或者上一次LCS反馈的QoS执行情况来判断当前这个请求,精度要求定为80m比较合适,所以给第一网元请求的精度信息里面标为80m。
实施方式二、第二核心网网元直接提供终端的精度为80m,是一个确切的数值,那么第一核心网网元直接转发这一精度信息到第一网元的请求中。
需要说明的是,此种映射方式是利用不用的定位精度的取值来表示映射得到的定位精度。
可选地,所述第一核心网网元根据所述定位服务请求,确定QoS种类的方式,包括以下一项:
A31、所述第一核心网网元获取所述定位服务请求中携带的QoS种类;
需要说的是,此种情况下是第二核心网网元在发送的定位服务请求中携带QoS种类,第一核心网网元直接获取该QoS种类即可。
A32、所述第一核心网网元对所述定位服务请求中携带的感兴趣的分析准确性信息进行映射,获取QoS种类;
需要说明的是,此种情况下,第二核心网网元在发送的定位服务请求中并未直接携带QoS种类,而是携带的感兴趣的分析准确性信息,此时第一核心网网元需要对该感兴趣的分析准确性信息进行映射,获取QoS种类。
需要说明的是,感兴趣的分析准确性信息(preferred分析准确性)可以是高中低几个梯度,在进行映射时,第一核心网网元是将准确性的几种梯度映射为QoS种类(QoS class)。可选地,映射方式的一种实现为:
当感兴趣的分析准确性信息为准确性要求较高的梯度时,应当映射为高级别QoS;
当感兴趣的分析准确性信息为准确性要求中等的梯度时,应当映射为中等级别QoS;
当感兴趣的分析准确性信息为准确性要求较低的梯度时,应当映射为低级别QoS。
可选地,所述终端定位服务请求中包括终端的标识,或终端的组标识。
需要说明的是,如果第二核心网网元向第一核心网网元请求某一位置附近所有终端的位置情况,或者直接提供了一个终端组(UE group)的组标识,那么第二核心网网元就需要获取一组终端的定位信息。
其中,所述终端的组标识的获取方式包括以下一项:
B11、所述第一核心网网元获取所述定位服务请求中携带的终端的组标识;
需要说明的是,如果第一核心网网元提供的是一个UE group的组标识,则第一核心网网元无需执行映射的过程。
B12、所述第一核心网网元将所述定位服务请求中携带的位置指示进行映射,获取终端的组标识。
需要说明的是,如果第二核心网网元提供的是某一个位置,第一核心网网元在收到后,第一核心网网元根据内部静态配置的列表或者是从其他核心网网元中获取到的映射信息,获取得到组标识。可选地,第一核心网网元可以一次向第五核心网网元申请多个终端的定位信息,即当第一网元为第五核心网网元的情况下,第一核心网网元发送的终端定位服务请求中可以携带终端的组标识,进一步地,第五核心网网元在收到终端的组标识之后,需要将这个组标识映射为一个UE list;在这之后,第五核心网网元针对这个UE list,在定位流程中分别获取每一个UE的定位信息。而当第一网元为第三核心网网元或第四核心网网元的情况下,即使第一核心网网元在获知需要获取一组终端的定位信息的情况下,也需要针对每个终端分别向第三核心网网元或第四核心网网元发送终端定位服务请求,即第一核心网网元一次只能请求一个终端的定位信息。
还需要说明的是,当所述第一网元为第五核心网网元时,所述第五核心网网元判断所述终端定位服务请求中请求的为一组终端的定位信息的情况下,可选地,在获取到每一个终端的定位信息后,分别发送给第一核心网网元,也就是说,GMLC网元在每搜集一次终端的定位信息,便会将该定位信息发送给NWDAF网元。可选地,在获取到一组终端中的所有终端的定位信息后,将所述一组终端的定位信息发送给第一核心网网元,也就是说,此时GMLC网元支持存储信息的功能,GMLC网元在获取到每个终端的定位信息后,先将定位信息进行存储,等获取到该组终端中的所有终端的定位信息后,再一同发送给NWDAF网元。
可选地,在所述第一网元为第四核心网网元的情况下,所述第四核心网网元的获取方式,包括:
所述第一核心网网元获取终端的第二网元的地址;
所述第一核心网网元在确定所述第二网元能够为终端提供服务的情况下,将所述第二网元确定为第四核心网网元,在确定所述第二网元不能够为终端提供服务的情况下,获取所述第二网元提供的第四核心网网元的地址。
需要说明的是,此种情况下,是根据终端标识(单个UE的标识或者UE group的组标识)来获取到LMF地址。如图3所示,具体实现流程为:
步骤1、NWDAF网元内部预设一个配置表,能够静态的查询到UE的LMF1的地址,LMF1提供后续的定位服务;
步骤2、NWDAF网元通过配置表查到了LMF1地址,如果LMF1判断当前无法给该终端提供定位服务,LMF1会告知NWDAF网元去修改本地静态配置,并将LMF2的地址告诉NWDAF网元。NWDAF网元修改静态配置之后,向LMF2发起终端定位服务请求。
步骤3、如果NWDAF网元没有预配置该信息,那么NWDAF网元会向其他核心网网元(该核心网网元包括但不限于:AMF、UDM、NRF等,该网元负责LMF地址的更新维护)查询某UE ID对应的当前LMF地址。
可选地,在所述第一网元为第三核心网网元的情况下,所述第三核心网网元的获取方式,包括:
所述第一核心网网元在确定至少一个终端的信息能够被所述第一核心网网元搜集和使用的情况下,从第六核心网网元获取至少一个第三核心网网元的地址;
其中,所述至少一个第三核心网网元为所述至少一个终端提供服务。
需要说明的是,本申请实施例中的第六核心网网元指的是UDM网元。当NWDAF网元需要统计终端的粗粒度和细粒度的定位信息时,会先向UDM网元检查用户意愿,查看该终端的信息能否被NWDAF网元搜集和使用;如果可以被收集和使用,则NWDAF网元向UDM网元获取终端当前所在的AMF地址。需要说明的是,NWDAF网元可以一次向UDM网元请求多个终端所在的AMF地址,因不同的终端可能对应不同的AMF网元,则UDM网元返回的是多个AMF地址;NWDAF网元也可以一次只向UDM网元请求一个终端所在的AMF地址,则UDM网元返回的是一个AMF地址。
需要说明的是,第一核心网网元可以不区分定位精度的类型,而将所有的定位精度的请求都发送给第一网元,可选地,第一核心网网元也可以只将某一类型的定位精度的请求发送给第一网元,具体地,所述第一核心网网元向第一网元发送终端定位服务请求的进一步可选地实现方式为:
所述第一核心网网元判断所述定位精度的类型;
所述第一核心网网元在所述定位精度的类型为第一精度类型的情况下,则向第一网元发送终端定位服务请求;
其中,所述第一网元为第四核心网网元或第五核心网网元。
需要说明的是,该第一精度类型指的是细粒度的精度类型,也就是说,此种情况下,第一核心网网元可以只向第四核心网网元或第五核心网网元请求细粒度的定位信息,而粗粒度的定位信息可以依据现有流程从AMF网元获取。
可选地,第一核心网网元在获取到终端的定位信息之后,在确定若获取的至少一个终端的定位信息的定位精度小于或等于所述第二核心网网元请求的定位精度,则获取至少一个终端的定位信息的实现的粒度和结果可信度;
所述第一核心网网元将至少一个终端的所述定位信息、所述实现的粒度和所述定位信
息的结果可信度发送给所述第二核心网网元。
可选地,所述第一核心网网元获取定位信息的实现的粒度的方式,包括:
将所述定位信息的定位精度映射为实现的粒度。
可选地,所述第一核心网网元获取定位信息的结果可信度的方式,包括:
基于所述定位信息的实现的QoS种类,确定定位信息的结果可信度。
需要说明的是,此处实现的是第一核心网网元在获取到终端的定位信息后,需要进行定位信息的定位精度的反映射,将其映射为实现的粒度,具体的,该实现的粒度可以理解第一网元在进行定位信息获取时,实际执行的定位精度对应的定位粒度。
还需要说明的是,第一核心网网元在向第二核心网网元返回终端的定位信息时,还需要将定位信息的结果可信度发送给第二核心网网元,以使得第二核心网网元根据该结果可信度来最终确定是否使用该定位信息。
下面对本申请实施例的具体应用进行详细说明如下。
首先,先对本申请实施例所涉及的各个网元所发送的信息进行说明如下。
如图4所示,图4中的Target MS表示目标终端,可以是一个UE,也可以是一组UE;LCS server可以是LMF网元、AMF网元或者GMLC网元;NWDAF网元是核心网网元,负责智能化统计和预测等功能;NWDAF consumer是NWDAF的消费者,可以是AMF、SMF、AF等。这里还需要说明的是,QoS class和LCS QoS class不能完全等价,存在映射关系。
具体的流程包括:
Step 1、NWDAF consumer向NWDAF网元发起服务请求,携带请求的参数,其中包含:
C11、Analytics ID(服务的特定标识);
C12、目标终端(可以是单个终端ID(SUCI、GPSI等),也可以是一组终端);
C13、Analytics filter(分析过滤器)(包含Area of Interest(兴趣区域)和Visited Area(s)of Interest(感兴趣的访问区域));
C14、分析时间(指示NWDAF统计或者预测的时间间隔);
C15、感兴趣Preferred结果的排列顺序(按照升序还是降序);
C16、Notification(通知)的关联ID与Notification的目标地址;
C17、preferred分析准确性(可以是高中低几个梯度)。
可选地,该请求中还可以携带目标终端的最大数量。
可选地,该请求中还可以携带定位粒度指示信息(即preferred定位信息的粒度),该定位粒度指示信息是带有梯度的指示信息,即用于指示多种梯度的定位粒度中的一种或多种,梯度包含定位精度从国家/地区范围到分米范围。粒度指示是一种类似index类型的标识方法,表示具体的定位精度数值。
可选地,该请求中还可以携带preferred QoS class,需要说明的是,如果NWDAF
consumer携带了该信息,则在step 2中可以直接对应到LCS的QoS class中,如果没有携带,则需要在step 2中进行映射。
Step 2、NWDAF网元在收到上述请求之后,将请求定位信息的消息发给LCS server。消息中包含:定位精度,QoS种类等信息。
Step 3、LCS server在与target MS进行定位过程中执行定位精度要求以及QoS要求,也就是LCS QoS中的精度(accuracy),包含水平精度(Horizontal accuracy)和垂直精度(Vertical accuracy)、以及QoS种类。
Step 4、定位过程中实现的定位精度以及LCS QoS在这一步通过LCS信令上报给LCS server。
Step 5、LCS server将实现的定位精度和QoS class上报给NWDAF网元,可选地,可以将定位时延、用户隐私验证等信息提供给NWDAF网元。
Step 6、收到实现的定位精度和QoS class之后,如果可以满足step 1中的要求,那么NWDAF网元将这些信息反向映射为实现的粒度和结果可信度,NWDAF网元在统计结果或者预测消息里将这些信息报给NWDAF consumer。
可选地,实现的定位精度映射为实现的粒度指示,根据step 2中进行反向映射;
实现的QoS种类作为结果可信度的计算因素之一,结果可信度的考虑方法如下:
D1、如果step 1中提供了preferred QoS class,那么NWDAF网元检验实现的QoS class和要求的是否一致。其他因素一致的情况下,如果实现的QoS class满足要求,那么结果可信度要比没有实现或者没有满足要求的结果可信度更高;
D2、如果step 1中没有提供preferred QoS class,那么根据step 2中将preferred分析准确性与QoS class的映射关系,将实现的QoS class与映射之后的QoS class进行对比。其他因素一致的情况下,如果实现的QoS class满足要求,那么结果可信度要比没有实现或者没有满足要求的结果可信度更高。
D3、如果无法满足在step 1中请求的粒度或者QoS要求,NWDAF网元判断LCS server回复的QoS、时延信息、隐私验证等信息,将相关原因报告给NWDAF consumer,这里的原因包括:链路时延较长、用户隐私验证失败等。
需要说明的是,NWDAF网元向LCS server发送请求,以及LCS server向Target MS发送请求的前提是用户的隐私验证或者用户意愿检查都通过。下面分别从不同的实现方式的角度对本申请实施例的具体实现流程进行说明如下。
首先需要说明的是,下文中的NWDAF、AMF、LMF、UDM、GMLC是为了描述简便,其均对应的是相应的网元。
具体应用情况一、NWDAF通过AMF获取UE的多种粒度的定位信息
需要说明的是,此种应用情况下的具体实现过程如图5所示,具体包括:
步骤501,NWDAF需要统计终端的定位信息(包括粗粒度和细粒度),会先向UDM检查用户意愿,查看该终端的信息能否被NWDAF搜集和使用。如果可以被收集使用,则
向UDM获取终端当前所在的AMF地址。
步骤502,NWDAF向AMF请求终端的定位信息,可以让AMF立即报告,也可以让终端基于事件报告(周期性、跨小区等);
需要说明的是,NWDAF发送的请求中还包括终端的标识(SUPI、GPSI等)、定位精度、定位的时间信息等内容。
步骤503,AMF收到请求之后判断当前的定位精度能否在AMF直接提供,如果判断可以满足NWDAF要求,则执行步骤504,如果无法满足,则执行步骤505-步骤509。
步骤504,AFM向NWDAF提供定位信息,包括步骤502中请求的内容,如果无法提供某些参数,则可选的,AMF提供相关的failure cause信息。
步骤505,AMF当前无法提供满足NWDAF粒度要求的定位信息,则寻找合适的LMF来发起定位流程获取,通过LMF选择流程找到合适的LMF。
步骤506,AMF向LMF请求定位信息,请求LMF提供满足精度要求的定位信息。
步骤507,根据AMF的要求,LMF发起定位流程,包括UE辅助(UE assisted)、UE为主(UE based)、网络辅助(Network assisted)等定位流程。在这一过程中,LMF可以获取到步骤506中要求的定位信息。

步骤509,AMF将收到的终端定位信息报告给NWDAF。
需要说明的是,NWDAF在向AMF请求终端的定位信息时需要逐个终端的进行请求,也就是说,NWDAF发送一次请求只能获取到一个终端的定位信息。
具体应用情况二、NWDAF通过GMLC向AMF获取细粒度的定位信息,从AMF获取粗粒度的定位信息
需要说明的是,此种应用情况下的具体实现过程如图6所示,具体包括:
步骤601,NWDAF判断需要统计的终端定位信息(包括粗粒度和细粒度),如果需要请求细粒度的定位信息,则执行步骤602-步骤610;如果请求粗粒度的定位信息,则执行步骤611-步骤612。
步骤602,NWDAF向GMLC请求终端的细粒度定位信息;
需要说明的是,如果是漫游场景下,NWDAF向主服务的GMLC(H-GMLC)发送请求,H-GMLC向拜访地的GMLC(V-GMLC)请求;如果是非漫游场景,NWDAF直接向H-GMLC发送请求。GMLC通过判断当前是否存有相关终端的定位信息,进一步判断能否满足NWDAF的要求,包括定位精度(accuracy)、时效性(maximum age of location)、时间戳(timestamp)等是否满足要求,如果能够满足,则执行步骤603;如果不能满足,则执行步骤604以及后续流程。
步骤603,GMLC验证当前存有的终端定位信息能够满足NWDAF的要求,GMLC直接返回符合要求的终端的定位信息。
步骤604,GMLC无法满足NWDAF的要求,通过与UDM的信令交互获取到当前终端的AMF地址,GMLC向AMF发起定位请求。
步骤605,AFM收到GMLC的请求之后,通过LMF选择流程来找到合适的LMF。
步骤606,AMF向LMF请求定位信息,请求LMF提供终端满足精度要求的定位信息。
步骤607,根据AMF的要求,LMF发起定位流程,包括UE辅助(UE assisted)、UE为主(UE based)、网络辅助(Network assisted)等定位流程。在这一过程中,LMF可以获取到步骤606中要求的定位信息。
步骤608,LMF将步骤607中所要求的定位信息回复给AMF。
步骤609,AMF将收到的终端定位信息报告给GMLC,如果无法提供某些参数,则可选的,AMF提供相关的failure cause信息。
步骤610,GMLC将终端定位信息报告给NWDAF。
步骤611,NWDAF判断当前需要粗粒度的定位信息,通过UDM获取当前终端的服务AMF地址,直接向AMF请求终端的定位信息。
步骤612,AMF将终端的定位信息报告给NWDAF,如果无法提供某些参数,则可选的,AMF提供相关的failure cause信息。
具体应用情况三、NWDAF均通过GMLC向LMF获取不同粒度的定位信息
需要说明的是,此种应用情况下的具体实现过程如图7所示,具体包括:
步骤701,NWDAF向GMLC请求终端的细粒度定位信息;
需要说明的是,如果是漫游场景下,NWDAF向H-GMLC发送请求,H-GMLC向V-GMLC请求;如果是非漫游场景,NWDAF直接向H-GMLC发送请求。GMLC通过判断当前是否存有相关终端的定位信息,进一步判断能否满足NWDAF的要求,包括定位精度(accuracy)、时效性(maximum age of location)、时间戳(timestamp)等的要求,如果能够满足,则执行步骤702;如果不能满足,则执行步骤703以及后续流程。
步骤702,GMLC验证当前存有的终端定位信息能够满足NWDAF的要求,GMLC直接返回符合要求的终端的定位信息。
步骤703,GMLC无法满足NWDAF的要求,通过与UDM的信令交互获取到当前终端的AMF地址,GMLC向AMF发起定位请求。
步骤704,AMF收到请求之后判断当前的定位精度能否在AMF直接提供,如果判断可以满足NWDAF粒度要求,则执行步骤705和步骤706,如果无法满足,则执行步骤707至步骤712。
步骤705,AMF向GMLC提供定位信息,满足步骤703中请求的内容和要求,如果无法提供某些参数,则可选的,AMF提供相关的failure cause信息。
步骤706,GMLC将终端定位信息报告给NWDAF。
步骤707,AMF当前无法提供满足NWDAF粒度要求的定位信息,则寻找合适的LMF
来发起定位流程获取,通过LMF选择流程找到合适的LMF。
步骤708,AMF向LMF请求定位信息,请求LMF提供满足精度要求的定位信息。
步骤709,根据AMF的要求,LMF发起定位流程,包括UE辅助(UE assisted)、UE为主(UE based)、网络辅助(Network assisted)等定位流程。在这一过程中,LMF可以获取到步骤708中要求的定位信息。
步骤710,LMF将步骤708中所要求的定位信息回复给AMF,如果某些参数无法提供或者无法满足,则可选地,LMF提供相关的failure cause信息。
步骤711,AMF将收到的终端定位信息报告给GMLC。
步骤712,GMLC将终端定位信息报告给NWDAF。
具体应用情况四、NWDAF直接向LMF获取细粒度的定位信息,通过AMF获取粗粒度的定位信息。
需要说明的是,此种应用情况下的具体实现过程如图8所示,具体包括:
步骤801,NWDAF判断请求粒度是从AMF还是从LMF获取。
步骤802,NWDAF通过UDM获取AMF地址,向AMF发送定位请求。
步骤803,AMF向NWDAF提供粗粒度的定位信息。
步骤804,NWDAF向LMF请求终端的定位信息。
步骤805,LMF判断请求的粒度是否可以直接提供。
步骤806,LMF向NWDAF提供本地存有符合要求的定位信息。
步骤807,LMF发起针对终端的定位流程。
步骤808,LMF向NWDAF回复符合要求的定位信息。
在这里引入NWDAF与LMF直接交互的接口。
在NWDAF进行判断,如果需要获取粗粒度的,则NWDAF向AMF发起,执行步骤802和步骤803;如果需要获取细粒度的定位信息,则NWDAF直接请求LMF发起定位流程,执行步骤804到步骤808。
步骤805中,如果LMF自身支持不同粒度定位信息的存储,并且存储的定位信息满足步骤804的要求,那么LMF在步骤806中直接提供,否则,LMF执行步骤807和步骤808。
具体应用情况五、NWDAF直接向LMF获取不同粒度的定位信息
需要说明的是,此种应用情况下的具体实现过程如图9所示,具体包括:
步骤901,NWDAF选择合适的LMF。

步骤904,LMF向NWDAF提供本地存有符合要求的定位信息。
步骤905,LMF发起针对终端的定位流程。
步骤906,LMF向NWDAF回复符合要求的定位信息。
在这里引入NWDAF与LMF直接交互的接口。
需要说明的是,此种应用情况下,完全由NWDAF与LMF的接口来替代定位信息获取的接口。NWDAF不做判断,直接将请求的精度信息请求给LMF,由LMF判断能否直接提供,若能够提供则直接返回定位信息给NWDAF,若不能提供,则执行步骤905和步骤906的过程。
需要说明的是,通过本申请实施例,NWDAF可以获取不同粒度的终端的定位信息,能够提高NWDAF的统计和预测服务水平。
