为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
1、5G网络系统架构:
在5G网络系统架构图如图2所示。其中,UE通过Uu接口与AN进行接入层连接,交互接入层消息及无线数据传输,UE通过N1口与AMF进行非接入层(NAS)连接,交互NAS消息。AMF是核心网中的移动性管理功能,SMF是核心网中的会话管理功能,AMF在对UE进行移动性管理之外,还负责将从会话管理相关消息在UE和SMF之间的转发。PCF是核心网中的策略管理功能,负责制定对UE的移动性管理、会话管理、计费等相关的策略。UPF是核心网中的用户面功能,通过N6接口与外部数据网络进行数据传输,通过N3接口与AN进行数据传输。UE通过Uu口接入5G网络后,在SMF的控制下建立PDU会话进行数据传输。
2、电子标签:
无线射频识别(RFID,Radio Frequency Identification)系统中,读写器是将电子标签中的信息读出,或将信息写入电子标签的装置,在RFID系统工作时,读写器在一个区域内发送射频能量形成电磁场,区域的大小取决于发射功率。读写器覆盖区域内的电子标签被触发,发送存储在其中的数据,或根据读写器的指令修改存储在其中的数据。读写器通过无线射频方式与电子标签进行非接触双向数据通信,对电子标签进行读写,从而达到识别目标和数据交换的目的。电子标签一般对电量消耗较少,甚至不需要连接电源或电池,例如无源的电子标签可以通过接受读写器传输来的微波信号,以及通过电磁感应线圈获取能量来对自身短暂供电,从而完成信息交换。RFID传输范围较短,可以应用于物品的本地管理和通信,例如仓库内的物品管理、档案管理、门卡管理、高速公路电子缴费等。
第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)网络中也考虑设计新型的电子标签,称为无源物联网(Passive IoT标签或者Ambient IoT标签,不同于RFID,这种电子标签可以使用3GPP网络的频率资源进行通信。本发明中的电子标签包括并不限于RFID标签、无源物联网设备(Passive IoT,Passive Internet of Things)标签、基于环境能量的物联网设备(Ambient IoT)标签。
电子标签可以应用在多种场景,例如用仓储物流,物品查找等,这些场景下,均需要获得电子标签的位置。而当电子标签引入3GPP网络后,可以利用3GPP网络对电子标签进行远程定位,从而帮助第三方准确的得知电子标签的位置。如何利用3GPP网络对电子标签定位,是目前还未解决的问题。
图3是本申请实施例的一个应用场景示意图,电子标签通过间接(Indirect)模式与网络进行连接,间接模式架构如图3所示。电子标签通过一个终端再连接到基站,电子标签的数据通过终端、基站、核心网和对应的服务器进行交互。终端可以增加电子标签的读写器功能,终端可以将自身所能收集的电子标签信息发送给核心网,核心网中具备存储功能的网元,或者是一个专门的网元,来保存UE标识和电子标签标识的关联关系。
本申请实施例提出一种定位方法,可以用于对电子标签进行定位,图4是根据本申请实施例的一种定位方法400的示意性流程图,该方法可以应用于图1-3中任一所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S410:终端设备根据电子标签的第一定位请求,获取电子标签的位置。
终端设备根据第一定位请求获取电子标签的位置,可以实现移动网络(如5G网络)对电子标签的定位。
终端设备可以从第一网络设备接收第一定位请求,该第一定位请求可以携带电子标签的标识(ID)、还可以携带该终端设备的ID。其中,电子标签的标识(ID)可以记为Tag ID,终端设备的ID可以记为UE ID。电子标签的位置也可以称为电子标签的位置信息(Tag的位置信息)、Tag ID的位置或Tag ID的位置信息等。
终端设备具有电子标签的读写器功能,因此能够对与其存在连接关系的电子标签进行读写操作、并确定与其存在连接关系的电子标签的位置;又由于第一定位请求中携带电子标签的标识,因此终端设备可以根据该电子标签的标识,确定该电子标签的位置。
第一定位请求中携带UE ID,因此接收到第一定位请求的终端设备可以根据其中的UE ID与自身的ID进行比较,以确定该第一定位请求是否是发送给自己的第一定位请求,避免消息传输等过程出现错误导致对电子标签定位的误操作。例如,如果第一定位请求中携带的UE ID与终端设备自身的ID一致,则说明该第一定位请求是发送给该终端设备的第一定位请求,终端设备可以根据该第一定位请求确定电子标签的位置;如果第一定位请求中携带的UE ID与终端设备自身的ID不一致,则说明该第一定位请 求不是发送给该终端设备的第一定位请求,则终端设备不进行电子标签的定位。
在一些实施方式中,第一网络设备可以为定位管理功能(LMF,Location Management Function)、网关移动定位中心(GMLC,Gateway Mobile Location Center)、AMF、或其它网元。
图5是根据本申请实施例的一种定位方法500的示意性流程图,图5示出了终端设备与第一网络设备的消息交互过程、以及终端设备和第一网络设备获取电子标签位置的相关流程。包括:
S510:终端设备从第一网络设备接收第一定位请求,该第一定位请求中可以携带Tag ID和/或UE ID。
S520:终端设备根据电子标签的标识,确定电子标签的位置(如电子标签的绝对位置和/或电子标签相对于终端设备的相对位置)。
具体地,终端设备可以根据Tag ID,确定电子标签的绝对位置;
或者,终端设备可以根据Tag ID,确定电子标签的相对位置;再利用电子标签的相对位置和终端设备的绝对位置,确定电子标签的绝对位置。终端设备可以触发定位流程来获取终端设备的绝对位置,例如终端设备触发基于Uu口的定位、或者其它定位方式,获取终端设备的绝对位置。
电子标签的相对位置或绝对位置可以由终端设备确定。例如,终端设备向电子标签发送信号,并接收电子标签返回的信号,根据发送信号和接收信号的相位差等信息,终端设备能够确定出该电子标签的相对位置。又如,终端设备可以联合附近的一个或多个其它终端设备,分别向电子标签发送信号、并计算该电子标签相对于各个终端设备的相对位置,根据计算出的多个相对位置确定该电子标签的绝对位置。
电子标签的绝对位置也可以称为电子标签的准确位置、Tag ID的绝对位置、或Tag ID的准确位置等。电子标签的相对位置也可以称为电子标签相对于终端设备的相对位置、Tag ID的相对位置、或Tag ID相对于终端设备的相对位置等。
S530:终端设备向第一网络设备发送电子标签的第一定位响应,该第一定位响应携带电子标签的位置。具体地,该第一定位响应可以携带电子标签的绝对位置和/或电子标签相对于终端设备的相对位置。在一些实施方式中,该第一定位响应中还可以携带Tag ID和/或UE ID。
具体地,如果S520中终端设备确定出的是电子标签的绝对位置,则第一定位响应中携带电子标签的绝对位置;
或者,如果S520中终端设备确定出的是电子标签的相对位置,则第一定位响应中携带电子标签的相对位置。
S540:第一网络设备根据电子标签的第一定位响应,获取电子标签的位置。
具体地,如果第一定位响应中携带电子标签的绝对位置,则第一网络设备可以直接从第一定位响应中获取电子标签的绝对位置;
或者,如果第一定位响应中携带电子标签的相对位置,则第一网络设备可以利用该相对位置以及终端设备的绝对位置,确定电子标签的绝对位置。
在确定或获取到电子标签的位置之后,第一网络设备可以向核心网其他网元发送电子标签的位置。核心网获取到电子标签的位置之后,可以将该位置提供给第三方应用(如AF),从而实现将电子标签的准确位置开放给第三方。
本申请实施例中,电子标签可以为RFID标签、无源物联网设备(Passive IoT)标签、或基于环境能量的物联网设备(Ambient IoT)标签等。
由图5所示的实施例可见,在电子标签的定位至少存在两种方式,第一种方式是由终端设备确定电子标签的绝对位置,第二种方式是由第一网络设备确定电子标签的绝对位置。
本申请实施例提出一种定位方法,可以用于对电子标签进行定位,图6是根据本申请实施例的一种定位方法600的示意性流程图,该方法可以应用于图1-3中任一所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S610:第一网络设备根据电子标签的第一定位响应,获取电子标签的位置。
例如,第一网络设备可以为LMF。
电子标签可以包括RFID标签、无源物联网设备(Passive IoT)标签、基于环境能量的物联网设备(Ambient IoT)标签中的至少之一。
在一些实施方式中,电子标签的第一定位响应可以携带电子标签相对于终端设备的相对位置和/或电子标签的绝对位置。
在第一定位响应携带电子标签相对于终端设备的相对位置的情况下,第一网络设备可以利用该相对位置以及终端设备的绝对位置,确定电子标签的绝对位置;
在第一定位响应携带电子标签的绝对位置的情况下,第一网络设备可以直接从第一定位响应中提取 该绝对位置。
在一些实施方式中,第一网络设备在接收第一定位响应之前,可以向终端设备发送电子标签的第一定位请求,该第一定位请求携带电子标签的标识和电子标签关联的终端设备的标识中的至少之一;之后,第一网络设备从该终端设备接收电子标签的第一定位响应,该第一定位响应可以携带电子标签的位置,还可以携带电子标签的标识和电子标签关联的终端设备的标识中的至少之一。
获取电子标签的位置之后,第一网络设备可以发送该电子标签的位置,从而将该电子标签的位置开放给第三方。
在一些实施方式中,在对电子标签进行定位之前,可以验证UE和/或电子标签的隐私,即验证电子标签和/或电子标签关联的终端设备是否允许将电子标签的位置信息开放给第三方。在验证通过的情况下,发起对电子标签的定位。通过这种方式,可以保证电子标签的安全;当第三方发起电子标签的定位请求时,只有在电子标签和/或电子标签关联的终端设备允许将电子标签的位置信息开放给第三方的情况下,才能够获取电子标签的位置并开放给第三方;并且,还可以由终端设备或核心网网元对电子标签的位置是否对第三方开放进行设置,例如,“电子标签和/或电子标签关联的终端设备是否允许将电子标签的位置信息开放给第三方”这一配置是可调整或修改的,该配置可以保存在UDM中,由终端设备或核心网网元在不同情况下进行调整或修改。
本申请实施例提出一种定位方法,图7是根据本申请实施例的一种定位方法700的示意性流程图,该方法可以应用于图1-3中任一所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S710:第二网络设备根据电子标签的第二定位请求,对电子标签和/或电子标签关联的终端设备进行验证。
例如,第二网络设备对电子标签和/或电子标签关联的终端设备是否允许将电子标签的位置信息开放给第三方进行验证。
在一些实施方式中,第二网络设备可以包括网关移动定位中心(GMLC,Gateway Mobile Location Center)、定位管理功能(LMF,Location Management Function)、AMF、或其它网元。
第二网络设备可以从第五网络设备接收电子标签的第二定位请求,第二定位请求可以携带电子标签的标识(Tag ID)。
例如,第五网络设备可以包括网络曝光功能(NEF,Network Exposure Function)或应用功能(AF,Application function)。如果第二网络设备从AF接收电子标签的第二定位请求,则第二网络设备还可以对AF的请求进行授权,即确定是否允许该AF请求位置信息。之前的实施例中,验证UE和/或电子标签的隐私,是直接对UE和/或电子标签进行隐私配置,对一个或多个UE和/或电子标签的隐私进行保护;在本实施例中,对AF的请求进行授权,是根据对AF的配置,实现对网络中涉及的UE和/或电子标签的隐私进行保护。例如,可以配置某个或某些AF允许请求电子标签的位置、配置某个或某些AF不允许请求电子标签的位置,根据该配置对AF的请求进行授权。当接收到来自AF的第二请求请求时,查找预先针对该AF的配置,如果预先配置该AF允许请求电子标签的位置,则对该AF的授权通过,之后进一步验证UE和/或电子标签的隐私、或者直接获取电子标签的位置;如果预先配置该AF不允许请求电子标签的位置,则对该AF的授权不通过,不需要获取电子标签的位置。
以第二网络设备是GMLC为例,针对第二网络设备的验证过程,至少可以存在以下两种方式:
方式一,GMLC与第三网络设备进行交互,对电子标签进行验证。
第三网络设备可以为统一数据管理功能(UDM,Unified Data Management)。UDM中可以预先保存多个电子标签的隐私信息。
例如,GMLC对Tag 1进行验证,通过与UMD交互,如果GMLC查询到UDM中保存有“Tag 1允许将位置信息开放给第三方”的信息,则GMLC对Tag 1的验证通过。
在电子标签允许将位置信息开放给第三方的情况下,GMLC可以从第四网络设备获取该电子标签关联的终端设备的信息;根据该电子标签关联的终端设备的信息,GMLC可以发送(如向AMF发送)该电子标签的第三定位请求,用于请求电子标签的位置信息。电子标签的第三定位请求可以携带电子标签的标识和该电子标签关联的终端设备的标识中的至少之一。其中,第四网络设备可以为网络功能(NF,Network Function),该NF可以存储终端设备和电子标签的关联关系。
在电子标签不允许将位置信息开放给第三方的情况下,GMLC可以向第五网络设备(如NEF或AF)返回拒绝定位请求的消息。
方式二,GMLC与第三网络设备进行交互,对电子标签关联的终端设备进行验证。
GMLC收到携带Tag ID的第二定位请求之后,为了对该Tag关联的终端设备进行验证,首先需要确定该Tag关联的终端设备。例如,第二网络设备可以从第四网络设备获取该电子标签关联的终端设备的信息。
确定Tag关联的终端设备之后,GMLC可以与第三网络设备(如UMD)交互,对电子标签关联的终端设备进行验证。UDM中可以预先保存多个UE及其关联的电子标签的隐私信息。例如,GMLC对Tag 1关联的UE 1进行验证,通过与UMD交互,如果GMLC查询到UDM中保存有“UE 1允许将关联的Tag 1的位置信息开放给第三方”的信息,则GMLC对UE 1的验证通过。
在UE 1允许将关联的Tag 1的位置信息开放给第三方的情况下,GMLC可以发送(如向AMF发送)该电子标签的第三定位请求,用于请求电子标签的位置信息。电子标签的第三定位请求可以携带电子标签的标识和该电子标签关联的终端设备的标识中的至少之一。
在UE 1不允许将关联的Tag 1的位置信息开放给第三方的情况下,GMLC可以向第五网络设备(如NEF或AF)返回拒绝定位请求的消息。
上述方式一能够实现对电子标签隐私的统一管理,UDM等网元中可以预先保存多个电子标签的隐私配置。上述方式二能够使得UE可以管理与自身关联的电子标签的隐私,UE可以预先与UMD等网元交互,允许将自身关联的某个或某些电子标签的位置开放给第三方。
在上述方式一和方式二中,第四网络设备可以为网络功能(NF),该NF可以存储终端设备和电子标签的关联关系。GMLC可以向NF发送查询请求,该查询请求携带电子标签的标识(Tag ID);GMLC从NF接收查询响应,该查询响应携带电子标签关联的终端设备的标识(UE ID)。进一步地,该查询响应还可以携带电子标签的标识(Tag ID)。

如果允许开放该电子标签的位置信息,则第二网络设备可以进一步传递电子标签的定位请求,如发送电子标签的第三定位请求。该第三定位请求中可以携带电子标签的标识和/或终端设备的标识。
当定位请求传递到第一网络设备后,第一网络设备可以将定位请求传递至终端设备,由终端设备确定电子标签的相对位置或绝对位置;如,第一网络设备可以向终端设备发送电子标签的第一定位请求,该第一定位请求中可以携带电子标签的标识和/或终端设备的标识。其中,第一网络设备可以为LMF、AMF或其他网元。
在接收到终端设备反馈的第一定位响应(该第一定位响应中携带电子标签的绝对位置和/或相对位置)后,第一网络设备可以直接获取第一定位响应中携带的电子标签的绝对位置;或者,第一网络设备可以获取第一定位响应中携带的电子标签的相对位置,并确定终端设备的绝对位置,利用该相对位置和终端设备的绝对位置,第一网络设备可以确定电子标签的绝对位置。
上述示例中,在确定电子标签的位置之前,首先对电子标签或电子标签关联的终端设备进行验证,在验证通过的情况下,允许获取电子标签的位置,从而保护电子标签的隐私,提高信息安全性。
