技术领域
本申请涉及无线终端技术领域，尤其涉及一种位置信息获取方法及电子设备。
背景技术
目前电子设备如手机等，可提供位置服务接口，该接口可供第三方应用程序(application，APP)请求并获取电子设备的地理位置信息。
然而，目前电子设备提供的位置服务的数据获取、结果计算和结果提供，均未被安全运行环境保护，存在被恶意修改的风险。例如，当手机被恶意攻击时，位置服务的数据获取、结果计算或结果提供过程可能被恶意修改，从而提供虚假的地理位置信息。又例如，安卓系统提供的模拟(mock)测试接口，可用于修改电子设备地理位置信息，使得地理位置信息的可靠性降低。另外，当手机被劫持时，或者当手机的开发者选项的“选择模拟位置信息应用”打开时，某些第三方APP可通过该位置服务接口向其他第三方APP提供手机的虚假地理位置信息。
因此目前电子设备提供的位置服务存在安全隐患。

具体实施方式
下面对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
为了提高电子设备提供的位置服务的可靠性，本申请实施例提供了一种位置信息获取方法。
示例性的，如图1所示为一种可能的电子设备101的硬件结构示意图。该电子设备101可用于执行本申请实施例提供的位置信息获取方法。
电子设备101又可称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。例如，具有无线连接功能的手持式设备、车载设备或车载设备等。电子设备101还可包括但不限于搭载

安卓、微软
Figure PCTCN2020109852-appb-000002
或者其它操作系统的便携式电子设备。上述便携式电子设备也可以是诸如具有触敏表面(例如触控面板)的膝上型计算机(laptop)等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。应理解，在本申请中，可以将终端称为终端设备、终端装置或电子设备等等。
应理解，如图1所示的电子设备101的硬件结构仅是一个示例。并且，电子设备101可 以具有比图中所示出的更多的或者更少的部件，可以组合两个或更多的部件，或者可以具有不同的部件配置。图中所示出的各种部件可以在包括一个或多个信号处理和/或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。
如图1所示，电子设备101包括处理器110、内部存储器121、外部存储器接口122、天线1、移动通信模块131、天线2、无线通信模块132、音频模块140、扬声器140A、受话器140B、麦克风140C、耳机接口140D、显示屏151、用户标识模块(subscriber identification module，SIM)卡接口152、摄像头153、按键154、传感器模块160、通用串行总线(universal serial bus，USB)接口170、充电管理模块180、电源管理模块181和电池182。在另一些实施例中，电子设备101还可以包括马达、指示器等。
其中，处理器110可以包括一个或多个处理单元。例如：处理器110可以包括应用处理器(application processor，AP)、调制解调处理器、图形处理器(graphics processing unit，GPU)、图像信号处理器(image signal processor，ISP)、控制器、视频编解码器、数字信号处理器(digital signal processor，DSP)、基带处理器、和/或神经网络处理器(neural-network processing unit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
在一些实施例中，处理器110中还可以设置存储器，用于存储指令和数据。示例的，处理器110中的存储器可以为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从该存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
内部存储器121可以用于存储计算机可执行程序代码，可执行程序代码包括指令。处理器110通过运行存储在内部存储器121的指令，从而执行电子设备101的各种功能应用以及数据处理。内部存储器121可以包括存储程序区和存储数据区。其中，存储程序区可存储操作系统，至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等。存储数据区可存储电子设备101使用过程中所创建的数据(比如音频数据、电话本等)等。此外，内部存储器121可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、通用闪存存储器(universal flash storage，UFS)等。
示例性的，内部存储器121可分别提供用于可信执行环境(trusted execution environment，TEE)以及用于富执行环境(rich execution environment，REE)的相互独立的存储空间。REE，或者称之为普通执行环境，是指终端中不具备特定安全功能的运行环境。例如，安卓
Figure PCTCN2020109852-appb-000003
操作系统就是一种富执行环境。TEE，是与REE共同存在于终端中的运行环境。例如，TEE可认为是一个安全操作系统。
基于独立的存储空间，TEE(或称TEE中的应用程序)可以访问REE的内存，REE(或称REE中的应用程序)无法访问受硬件保护的TEE内存。相应地，处理器110可包括与TEE以及REE分别对应的处理器，分别用于执行TEE和REE中的指令(或称代码、程序)，例如，与TEE以及REE分别对应的处理器可分别执行TEE和REE中的指令，分别在TEE和REE中运行应用程序。其中，在TEE中的可执行指令被执行前，需经过验证(validate)，而REE中的可执行指令在执行前不需要被验证。另外，运行于REE中的应用程序，只能通过调用特定的接口，如特定的应用程序编程接口(application programming interface，API)，与TEE进行通信，并且这些REE须经过TEE的安全认证。目前，电子设备中广泛采用TEE与REE结合的允许方案，来增强电子设备整体运行环境的可靠性。
TEE可通过存储器以及处理器等硬件的支撑，具有安全能力并且能够满足一定的安全需求，可实现与REE相隔离的运行机制。由于TEE有自身的运行空间，定义了严格的保护措施，因此比REE的安全级别更高，能够保护TEE中的资产(如数据，软件等)免受攻击，抵抗特定类型的安全威胁。只有授权的安全应用才能在TEE中执行，同时它也保护了安全软件的资源和数据的机密性。相比REE，由于其隔离和权限控制等保护机制，TEE能够更好的保护数据和资源的安全性。
电子设备101中，TEE访问的软硬件资源与REE访问的软硬件资源是相互隔离的，电子设备101上的软硬件资源可以分别标识为这两种执行环境状态，标识为安全执行状态的软硬件资源只能由TEE执行环境所访问，标识为非安全执行状态的软硬件资源则可以被这两种执行环境所访问。从而TEE构造了一个与REE隔离的安全运行环境，可以为授权的可信软件提供安全的执行环境。
外部存储器接口122可以用于连接外部存储卡(例如，Micro SD卡)，实现扩展电子设备101的存储能力。外部存储卡通过外部存储器接口122与处理器110通信，实现数据存储功能。例如将音乐、视频等文件保存在外部存储卡中。
天线1和天线2用于发射和接收电磁波信号。电子设备101中的每个天线可用于覆盖单个或多个通信频带。不同的天线还可以复用，以提高天线的利用率。例如：可以将天线1复用为无线局域网的分集天线。在另外一些实施例中，天线可以和调谐开关结合使用。
移动通信模块131可以提供应用在电子设备101上的包括2G/3G/4G/5G等无线通信的解决方案。移动通信模块131可以包括至少一个滤波器、开关、功率放大器、低噪声放大器(low noise amplifier，LNA)等。移动通信模块131可以由天线1接收电磁波信号，并对接收的电磁波信号进行滤波、放大等处理，传送至调制解调处理器进行解调。移动通信模块131还可以对经调制解调处理器调制后的信号放大，经天线1转为电磁波辐射出去。在一些实施例中，移动通信模块131的至少部分功能模块可以被设置于处理器110中。在一些实施例中，移动通信模块131的至少部分功能模块可以与处理器110的至少部分模块被设置在同一个器件中。例如，移动通信模块131可以向电子设备200发送语音，也可以接收电子设备200发送的语音。
调制解调处理器可以包括调制器和解调器。其中，调制器用于将待发送的低频基带信号调制成中高频信号。解调器用于将接收的电磁波信号解调为低频基带信号。随后解调器将解调得到的低频基带信号传送至基带处理器处理。低频基带信号经基带处理器处理后，被传递给应用处理器。应用处理器通过音频设备(不限于扬声器140A、受话器140B等)输出声音信号，或通过显示屏151显示图像或视频。在一些实施例中，调制解调处理器可以是独立的器件。在另一些实施例中，调制解调处理器可以独立于处理器110，与移动通信模块131或其他功能模块设置在同一个器件中。
移动通信模块131还可包括基带芯片(modem)。基带芯片可用于提供电子设备101附近通信基站的标识，该标识可用于区分通信基站。例如，通信基站的标识可包括小区的标识(cell ID)，cell ID可用于标识小区所属的通信基站。通信基站的标识可作为一种网络定位信息，用于确定电子设备101的网络定位结果。以cell ID为例，基带芯片可提供能够检测到信号的小区的cell ID。
示例性的，以上调制解调处理器可用于执行基带芯片的功能，或者，基带芯片也可是 独立于调制解调处理器的芯片。
无线通信模块132可以提供应用在电子设备101上的包括无线局域网(wireless local area networks，WLAN)(如WIFI网络)、蓝牙(bluetooth，BT)、全球导航卫星系统(global navigation satellite system，GNSS)、调频(frequency modulation，FM)、近距离无线通信技术(near field communication，NFC)、红外技术(infrared，IR)等无线通信的解决方案。无线通信模块132可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块132经由天线2接收电磁波信号，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块132还可以从处理器110接收待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。例如，无线通信模块132可以将电子设备101采集的用户1使用语言1的语音发送给翻译服务器，也可以将移动通信模块131接收到的电子设备200采集的用户2使用语言2的语音发送给翻译服务器，还可以接收翻译服务器发送的翻译结果。
无线通信模块132可包括无线保真(wireless fidelity，WIFI)网络芯片(或称WLAN网络芯片)。WIFI芯片用于支持终端设备101接入WIFI网络或其他WLAN网络。在本申请中，WIFI芯片还可用于提供WLAN网络的媒体访问控制地址(media access control address，MAC address)，MAC地址也可被称为局域网地址(local area network address，LAN address)，以太网地址(ethernet address)或物理地址(physical address)中的至少一个信息。以上信息可用于确定电子设备101的网络定位结果，如经纬度、高度、定位精度等信息。
以上无线通信技术可以包括全球移动通讯系统(global system for mobile communications，GSM)、通用分组无线服务(general packet radio service，GPRS)、码分多址接入(code division multiple access，CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分码分多址(time-division code division multiple access，TD-SCDMA)、长期演进(long term evolution，LTE)、BT、GNSS、WLAN、NFC、FM、和/或IR技术等。

以上星历服务器可用于提供卫星星历数据(或称星历)，卫星星历数据又可被称为两 行轨道数据(two-line orbital element，TLE)，可用于卫星芯片获取卫星定位结果。卫星星历可用于描述卫星的位置和移动速度的关系。电子设备101中的卫星芯片可根据卫星星历数据快速定位卫星，之后卫星芯片可通过定位的卫星确定卫星定位结果，以实现卫星定位结果的快速确定。具体来说，当进行GPS定位时，电子设备101可通过卫星星历数据快速定位GPS系统中的定位卫星，并根据定位卫星提供的数据确定电子设备101的卫星定位结果。
基于如图2所示架构，安全位置TA可获取电子设备101的位置信息，其中，电子设备101的位置信息可包括电子设备101的卫星定位结果和/或电子设备的网络定位结果。由于电子设备101的位置信息由部署于TEE中的安全位置TA获取，因此可提高获取的电子设备101的位置信息的可靠性。
本申请中，安全位置TA可根据业务方的定位业务请求获取电子设备101的位置信息，并向业务方提供电子设备101的位置信息。其中，业务方可通过多种方式向安全位置TA请求电子设备101的位置信息。
下面，对业务方请求安全位置TA获取电子设备101的位置信息的方式，以及相对应的安全位置TA向业务方发送电子设备101的位置信息的方式予以说明。

方式二、业务方通过TA调用安全位置TA。
例如，业务方包括部署于REE中的APP以及包括部署于TEE中的TA(以下称该TA为业务方TA)。在请求电子设备101的位置信息时，业务方可通过业务方TA调用安全位置TA，从而令安全位置TA获取电子设备101的位置信息。

在请求电子设备101的位置信息时，业务方applet可通过HCI请求(如通过HCI发送的请求消息)调用安全位置服务，触发安全位置服务调用安全位置TA，从而令安全位置 TA获取电子设备101的位置信息。其中，业务方applet在调用安全位置服务时，将业务方applet的AID发送至安全位置服务，并由安全位置服务将业务方applet的AID发送至安全位置TA。
在获取电子设备101的位置信息之后，安全位置TA可通过SE的应用程序编程接口(application programming interface，API)向业务方applet发送电子设备101的位置信息。其中，安全位置TA可通过SE API选择业务方applet的AID，从而将电子设备101的位置信息发送至业务方的applet。
以上SE是指具备防篡改、防硬件攻击能力的硬件单元。SE可具备独立的处理器，能够为在其中运行的applet(或称SE中的应用)或第三方业务提供安全的运行环境，并且能够保证存储在其中的资产的安全性和机密性。常见的安全单元有嵌入式安全单元(embedded secure element，eSE)，集成到手机系统级芯片(system on chip，SoC)之中的inSE，通用集成电路卡(universal integrated circuit card，UICC)等。SE中的applet可通过应用标识AID进行标识。applet可通过HCI调用REE中约定的APP。
采用以上方式一、方式二以及方式三或者方式一、方式二以及方式三的任意组合，能够令业务方请求从安全位置TA获取电子设备101的位置信息，因此可提高业务方获取电子设备101的位置信息的可靠性。
下面分别介绍安全位置TA根据业务方的定位业务请求获取电子设备101的卫星定位结果以及网络定位结果的过程。
如图3所示，安全位置TA根据业务方的定位业务请求获取电子设备101的卫星定位结果的过程可包括以下步骤：
步骤S101：安全位置TA通过TEE OS提供的TEE传感器接口，将电子设备101的卫星星历数据发送至智能传感集线器。其中，安全位置TA部署于TEE中。
卫星星历数据又可被称为两行轨道数据，是用于描述卫星的位置和移动速度的关系的数据。卫星星历数据可用于确定卫星的运行位置。卫星星历数据可由安全位置TA存储。
步骤S102：智能传感集线器将电子设备101的卫星星历数据发送至卫星芯片。
步骤S103：卫星芯片根据电子设备101的卫星星历数据获取电子设备101的卫星定位结果。在进行卫星定位计算时，卫星芯片可在电子设备101的卫星星历数据的协助下快速确定定位卫星的位置，并根据从定位卫星接收到的数据确定设备101的卫星定位结果。
示例性的，定位卫星包括但不限于基于GPS、BDS、GLONASS、伽利略或者QZSS等定位系统的定位卫星，本申请不予具体限定。
步骤S104：卫星芯片将电子设备101的卫星定位结果，通过智能传感集线器以及TEE传感器接口发送至安全位置TA。
采用以上流程，可由部署于电子设备的TEE中的安全位置TA获取电子设备的卫星定位结果，由于TEE中的TA能够避免受到恶意攻击和劫持，因此相对现有技术可以避免电子设备的卫星定位结果的获取过程中电子设备的卫星定位结果被修改，从而提高了获取的电子设备的位置信息的可靠性。
示例性的，如图4所示，安全位置TA可通过以下流程获取并存储卫星星历数据：
S201：部署于REE中的安全位置服务每隔设定时长(如24小时)，通知安全位置TA获取电子设备的卫星星历数据。
S202：安全位置TA通过TEE OS提供的TEE通信接口，向星历服务器发送第一请求， 第一请求可用于请求电子设备的卫星星历数据。示例性的，安全位置TA可通过TEE OS提供的TEE通信接口调用部署于REE中的通信协议服务，并借助通信协议服务通过TLS之下的低层通信协议从星历服务器获取卫星星历数据。
S203：星历服务器通过TEE通信接口将卫星星历数据传回安全位置TA。
S204：安全位置TA存储卫星星历数据。
采用以上流程，可由部署于电子设备的TEE中的安全位置TA获取电子设备的星历数据，由于TEE通信接口可以和星历服务器建立安全的通信通道，安全位置TA获得的星历数据不会在传输过程中被恶意修改或替换，是可信的。
如图5所示，安全位置TA根据业务方的定位业务请求获取电子设备101的网络定位结果的过程可包括以下步骤：
S301：安全位置TA通过TEE OS提供的TEE传感器接口，向智能传感集线器发送第二请求，第二请求可用于请求电子设备101的网络定位信息。在本申请中，电子设备101的网络定位信息可包括电子设备101周围环境的WIFI网络的MAC地址和/或周围的cell ID。
S302：智能传感集线器分别获取电子设备101的网络定位信息。智能传感集线器可分别从电子设备的低层获取电子设备101的网络定位信息。一种可能的实施方式是：智能传感集线器可从电子设备101的WIFI芯片获取WIFI芯片能够检测到的WIFI网络的MAC地址。和/或，智能传感集线器可从电子设备101的基带芯片获取基带芯片检测到的cell ID。
S303：智能传感集线器将WIFI网络的MAC地址和/或cell ID，通过TEE传感器接口传回安全位置TA。
S304：安全位置TA通过TEE OS提供的TEE通信接口向网络定位服务器发送电子设备101的网络定位信息。示例性的，安全位置TA可通过TEE通信接口调用部署于REE中的通信协议服务，借助通信协议服务的TLS之下的底层通信协议，将网络定位信息(如WIFI网络的MAC地址和cell ID)发送至网络定位服务器。
S305：网络定位服务器根据电子设备101的网络定位信息确定电子设备101的网络定位结果。
S306：网络定位服务器通过TEE通信接口将电子设备101的网络定位结果传回安全位置TA。
采用以上流程，可由部署于电子设备的TEE中的安全位置TA获取电子设备的网络定位结果，由于TEE通信接口可以和网络定位服务器建立安全的通信通道，安全位置TA上传的网络定位信息和获得的网络定位结果，不会在传输过程中被恶意修改或替换，是可信的。
应理解，安全位置TA可根据业务方的定位业务请求执行以上S101-S104和/或S301-S306所示步骤。
示例性的，S101-S104以及S301-S306所示步骤均可在安全位置TA接收到业务方的定位业务请求后执行。
该示例中，当S101-S104以及S301-S306所示步骤均执行时，安全位置TA可根据以下策略决定电子设备101的卫星定位结果和/或电子设备101的网络定位结果是否可用，以进一步提高电子设备101的卫星定位结果和/或电子设备101的网络定位结果的可靠性。
安全位置TA可根据级别设置卫星定位结果对应的超时时长(以下称为第一超时时长)和网络定位结果对应的超时时长(以下称为第二超时时长)，并根据第一超时时长及第二 超时时长决定电子设备101的卫星定位结果和/或电子设备101的网络定位结果是否可用。以上第一超时时长与第二超时时长可以相同或不同。
其中，第一超时时长可以从安全位置TA向智能传感集线器发送电子设备的卫星星历数据后(时)开始计时。第二超时时长可以从安全位置TA向智能传感集线器发送第二请求后开始计时。另外，第一超时时长和/或第二超时时长也可自安全位置TA接收到来自业务方的定位请求后(时)起算。
判断结果一：当第一超时时长到达但安全位置TA未接收到电子设备101的卫星定位结果，并且，第二超时时长到达但安全位置TA未接收到电子设备101的网络定位结果时，安全位置TA判断电子设备101的卫星定位结果和电子设备101的网络定位结果均不可用。此时安全位置TA判断提供位置服务失败。安全位置TA可向业务方发送失败响应。
判断结果二：当第一超时时长到达前，安全位置TA接收到了电子设备101的卫星定位结果，并且，第二超时时长到达但安全位置TA未接收到电子设备101的网络定位结果时，安全位置TA可将电子设备101的卫星定位结果作为电子设备101的位置信息。此时安全位置TA可向业务方发送电子设备101的卫星定位结果。
判断结果三：当第一超时时长到达但安全位置TA未接收到电子设备101的卫星定位结果，并且，在第二超时时长到达前，安全位置TA接收到了电子设备101的网络定位结果时，安全位置TA可将电子设备101的网络定位结果作为电子设备101的位置信息。此时安全位置TA可向业务方发送电子设备101的网络定位结果。
应理解，若在第一超时时长到达前，安全位置TA接收到了电子设备101的卫星定位结果，并且，在第二超时时长到达前，安全位置TA也接收到了电子设备101的网络定位结果，则安全位置TA可将电子设备101的卫星定位结果和/或电子设备101的网络定位结果发送至业务方。在一种具体的示例中，由于卫星定位的精度高于网络定位的精度，安全位置TA可仅向业务方发送电子设备101的卫星定位结果，实现更高精度的定位。
应理解，本申请中举例以上实施方式仅仅是举例说明。在实际使用中，业务方可以根据自身需要，请求仅获取电子设备101的卫星定位结果、或者请求仅获取电子设备101的网络定位结果，或者如上述实施例所举例的，请求同时获取电子设备101的卫星定位结果和网络定位结果。
另外，业务方还可以根据自身需要，请求优先获取电子设备101的卫星定位结果或网络定位结果，则电子设备101的安全位置TA可优先向业务方提供其请求优先获取的定位结果。如果安全位置TA无法获得该优先获取的定位结果，则安全位置TA可向业务方提供其他的定位结果。
另外应理解，安全位置TA可将电子设备101的卫星定位结果以及电子设备101的网络定位结果中先接收到的一个，作为电子设备101的位置信息发送至业务方，以实现更加快速的定位。在用户未开启电子设备101的卫星定位功能时，安全位置TA可将电子设备101的网络定位结果作为电子设备101的位置信息发送至业务方。
