Description

一种定位方法及电子设备
本申请要求于2014年09月25日提交中国专利局、申请号为201410499303.2，发明名称为“一种定位方法及电子设备”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。
技术领域
本发明涉及通信技术领域，尤其涉及一种定位方法及电子设备。
背景技术
定位服务已经发展为人们日常生活中一项重要的公共服务，其核心技术在于定位技术。
当前主流的定位技术有：使用定位卫星进行定位的全球定位系统(Global Position System，GPS)技术、通过获取待定位终端所在的小区识别码(CELL ID)来确定其所在的位置的CELL ID定位技术、使用无线保真(Wireless Fidelity，WIFI)或蓝牙等有源信号设备来进行定位的定位技术。
另外，还有地磁定位技术，地磁定位技术的理论依据为：地球上任意地点的地磁场强度均不相同，且地磁场强度与经纬度一一对应，因此只要测量出待定位终端所处位置的地磁场强度，就可以实现定位。
然而，GPS技术和使用有源信号设备的定位技术，对信号源依赖大，在信号不佳或不稳定时，会出现间断，不能提供持续稳定的定位服务。CELL ID定位技术虽稳定，但定位精度低，只能提供小区范围的定位精度。另外，由于地磁信息会受地表形态的干扰，可能会出现多个地点的地磁信息相近或相等的情况，故地磁定位技术的定位准确度较低。
也就是说，现有的定位技术存在定位稳定性、定位精度和定位准确度不能兼顾的技术问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在介绍本发明实施例之前，先介绍本发明实施例中定位方法所对应的系统，如图1所示，图1为一种用于实施本发明定位方法的系统，该系统包括：定位服务器、待定位终端和附近的多个终端(例如：第一终端、第二终端、以及第三终端等等，图1中只示意出两个终端)，其中，所述系统，具体可以是基于 UMTS的通信系统，也可以是基于全球移动通信(Global System For Mobile Communication，GSM)的通信系统、还可以是基于长期演进系统(Long Term Evolution，LTE)的通信系统，还可以是基于码分多址(Code Division Multiple Access，CDMA)的通信系统，还可以是基于时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)等，在本申请中不作限制。
实施例一
本实施例提供一种定位方法，如图2所示，该定位方法包括：
步骤S201，获取待定位终端的小区识别码；
步骤S202，根据所述待定位终端的小区识别码，确定出所述待定位终端的至少一个邻近终端，所述至少一个邻近终端中每个邻近终端的小区识别码与所述待定位终端的小区识别码相同；
步骤S203，获取所述至少一个邻近终端中每个邻近终端所处位置的地磁信息和所述待定位终端所处位置的地磁信息，以生成所述待定位终端的地磁信息组；
步骤S204，根据所述待定位终端的地磁信息组，获取所述待定位终端所处的地理位置信息。
在具体实施过程中，本实施例提供的定位方法可以应用于手机、平板电脑或智能手表等终端；也可以应用于定位服务器，在本实施例中不作限制。
在具体实施过程中，根据获取地理位置信息的方式不同，本实施例提供的定位方法可以分为初次定位和二次定位两种情况，下面以所述定位方法应用于待定位终端为例，分别进行说明：
先介绍初次定位。
即在实测的地磁信息图中确定出与待定位终端的地磁信息组匹配的区域，再根据大地坐标系获取地理位置信息，具体实现步骤如下：
首先，执行步骤S201，获取待定位终端的CELL ID。
在具体实施过程中，待定位终端可以是在接收到用户打开定位应用，并进 行定位触发操作后，触发获取待定位终端的CELL ID；也可以是接收到其余设备发送的定位指令后，触发获取待定位终端的CELL ID，在本实施例中不作限制。
具体来讲，对于获取待定位终端的CELL ID的方式，以待定位终端安装安卓操作系统为例，待定位终端可以调用CellLocation接口来与服务器、基站或无线网络控制器(Radio Network Controller，RNC)通信，进而获取CELL ID。
在通过步骤S201，获取待定位终端的CELL ID后，进入步骤S202，根据所述待定位终端的CELL ID，确定出所述待定位终端的至少一个邻近终端，所述至少一个邻近终端中每个邻近终端的CELL ID与所述待定位终端的CELL ID相同。
在具体实施过程中，确定所述至少一个邻近终端的方式，至少可以分为以下两种：根据CELL ID来确定，根据CELL ID和上下文信息确定，下面分别进行说明：
第一种，根据CELL ID来确定。
即确定CELL ID与所述待定位终端的CELL ID相同的终端为所述至少一个邻近终端。
在具体实施过程中，待定位终端可以与服务器通信来确定出CELL ID与所述待定位终端的CELL ID相同的终端。
具体来讲，即待定位终端将自身的CELL ID发送至服务器。服务器从存储单元中查询出包含该CELL ID的上下文列表，或服务器与该CELL ID对应的基站通信获取该CELL ID对应终端的上下文列表。从而确定出所述至少一个邻近终端。
例如：当待定位终端Ma的CELL ID为c1982时，所述上下文列表可以如表1所示：
终端标识 CELL ID 蓝牙标识 Wifi标识
Mb c1982 {b1,b2,b3} 01
Mc c1982 {b1,a1,a4} 02
Md c1982 {b1,a2,a5} 01
Me c1982 {c1,c2,c3} 03
表1
表1中确定出的待定位终端Ma的所述至少一个邻近终端包括：Mb、Mc、Md和Me。
具体来讲，确定CELL ID与所述待定位终端的CELL ID相同的终端为所述至少一个邻近终端，由于不需要对其余数据进行分析处理，能快速确定出邻近终端，提高定位效率。
进一步，由于在定位过程中，不需要依赖WIFI或蓝牙等间断性可用的信号源，避免了间断性定位失败的情况，提高了定位可靠性。
第二种，根据CELL ID和上下文信息确定。
在具体实施过程中，可以先根据CELL ID来确定预邻近终端集合，再分析上下文信息，从预邻近终端集合中确定出邻近终端；也可以先根据上下文信息来确定预邻近终端集合，再根据CELL ID，从预邻近终端集合中确定出邻近终端。
对于先根据CELL ID来确定预邻近终端集合，再分析上下文信息确定出邻近终端的情况，具体实施步骤可以为：
根据所述待定位终端的CELL ID，确定出至少一个预邻近终端，所述至少一个预邻近终端包括CELL ID与所述待定位终端的CELL ID相同的预邻近终端；
获取所述至少一个预邻近终端中每个预邻近终端的上下文信息，和所述待定位终端的上下文信息；
从所述至少一个预邻近终端中，确定出上下文信息与所述待定位终端的上下文信息匹配的预邻近终端，组成所述待定位终端的至少一个邻近终端。
在具体实施过程中，确定出至少一个预邻近终端和获取上下文信息的方法， 与上述第一种情况中，根据CELL ID来确定邻近终端和获取邻近终端上下文信息的方法相同，在此不再累述。
在本申请实施例中，所述上下文信息可以为WIFI标识、蓝牙标识和GPS参数中的一种或多种的组合。
在具体实施过程中，当所述上下文信息为WIFI标识和/或蓝牙标识时，所述确定出上下文信息与所述待定位终端的上下文信息匹配的预邻近终端，具体为确定出上下文信息与所述待定位终端的上下文信息相同的预邻近终端。
当所述上下文信息为GPS参数时，所述确定出上下文信息与所述待定位终端的上下文信息匹配的预邻近终端，具体为确定出上下文信息与所述待定位终端的上下文信息的匹配度高与预设值的预邻近终端。
例如：同样请参考表1，以所述上下文信息为蓝牙标识为例，当待定位终端Ma的CELL ID为c1982，蓝牙标识为b1时，表1中确定出的待定位终端Ma的所述至少一个邻近终端包括：Mb、Mc和Md，不包括Me。
以所述上下文信息为WIFI标识为例，当待定位终端Ma的CELL ID为c1982，WIFI标识为01时，表1中确定出的待定位终端Ma的所述至少一个邻近终端包括：Mb和Md，不包括Mc和Me。
对于先根据上下文信息确定预邻近终端集合，再根据CELL ID来确定邻近终端的情况，具体实施步骤可以为：
根据所述待定位终端的上下文信息，确定出上下文信息与所述待定位终端的上下文信息匹配的至少一个预邻近终端；
从所述至少一个预邻近终端中，确定出CELL ID与所述待定位终端的CELL ID相同的预邻近终端，组成所述待定位终端的至少一个邻近终端。
例如：
以所述上下文信息为蓝牙标识为例，待定位终端扫描获取附近的蓝牙设备的蓝牙标识，确认扫描到的蓝牙设备为所述至少一个预邻近终端，并向扫描到的蓝牙设备发送蓝牙连接请求，以建立蓝牙通信连接；再发送请求以获取扫描到的蓝牙设备的CELL ID，确定出CELL ID与所述待定位终端的CELL ID相同 的设备为邻近终端。
以所述上下文信息为GPS参数为例，待定位终端将自身的GPS参数发送至服务器，服务器确定出GPS参数与待定位终端的GPS参数表示的位置接近的终端作为所述至少一个预邻近终端，并将所述至少一个预邻近终端的CELL ID发送至待定位终端，以确定出CELL ID与所述待定位终端的CELL ID相同的设备为邻近终端。
具体来讲，结合CELL ID和上下文信息来确定所述至少一个邻近终端，能进一步缩小邻近终端的范围，提高确定出的邻近终端的准确度，提高定位精度。
在通过步骤S202确定出所述至少一个邻近终端后，进入步骤S203，即获取所述至少一个邻近终端中每个邻近终端所处位置的地磁信息和所述待定位终端所处位置的地磁信息，以生成所述待定位终端的地磁信息组。
具体来讲，地磁信息可以包括与水平面平行的X方向分量值、与水平面平行Y方向分量值、与水平面垂直的Z方向垂直分量值和地磁精度值，其中，X方向分量值表示沿X方向的地磁强度，Y方向分量值表示沿Y方向的地磁强度，垂直分量值表示沿Z方向的地磁强度，地磁精度值表示各方向分量值的测量精度。
例如，地磁信息可以为{x,y,z,acc}，其中，x为X方向分量值，y为Y方向分量值，z为垂直分量值，acc为地磁精度值。
在具体实施过程中，所述待定位终端所处位置的地磁信息可以通过设置在所述待定位终端上的地磁感应器感应获得。
在具体实施过程中，所述至少一个邻近终端中每个邻近终端所处位置的地磁信息可以由待定位终端通过WIFI连接或蓝牙连接与所述至少一个邻近终端直接通信获得，也可以由待定位终端通过服务器与所述至少一个邻近终端通信获得，在本实施例中不作限制。
在本申请实施例中，为了进一步缩小待定位终端的地磁信息组的范围，提高定位精度，可以根据地磁信息中的垂直分量值，进一步缩小用于定位的邻近终端的垂直分布范围，具体步骤包括：
获取所述至少一个邻近终端中每个邻近终端所处位置的地磁信息和所述待定位终端所处位置的地磁信息，组成预地磁信息组；
从所述预地磁信息组中，确定出垂直分量值与所述待定位终端所处位置的地磁信息的垂直分量值的差值小于预设阈值的地磁信息，组成所述待定位终端的地磁信息组。
具体来讲，根据地磁信息的垂直分量值，筛选出与待定位终端基本处于同一水平面的邻近终端的地磁信息，组成地磁信息组，进一步缩小了定位范围，提高了定位精度。
在通过步骤S203，生成所述待定位终端的地磁信息组后，执行步骤S204，即根据所述待定位终端的地磁信息组，获取所述待定位终端所处的地理位置信息。
在本申请实施例中，获取所述待定位终端所处的地理位置信息的方式可以为，发送所述待定位终端的地磁信息组至定位服务器；再接收所述定位服务器基于所述待定位终端的地磁信息组，返回的所述待定位终端所处的地理位置信息。
具体来讲，定位服务器返回的所述待定位终端所处的地理位置信息，可以是定位服务器先在实测的地磁信息图中确定出与待定位终端的地磁信息组匹配的区域，再根据大地坐标系获取该区域的大地坐标和地理位置信息。
在具体实施过程中，为了提高后续进行定位的效率，定位服务器在确定出待定位终端的地理位置信息后，可以将待定位终端的小区标识码、地磁信息组、大地坐标和地理位置信息对应存储，以供后续定位过程中使用。
具体来讲，在初次定位时，先通过稳定性高的CELL ID定位技术，确定出小区识别码与待定位终端的目标小区识别码相同的邻近终端，再根据邻近终端所处位置的地磁信息和待定位终端所处位置的目标地磁信息生成地磁信息组，来通过地磁定位技术定位出地理位置信息，不仅延续了CELL ID定位技术的稳定性，还通过分级定位提高了定位精度。
在介绍了初次定位后，接下来，介绍二次定位。
二次定位即通过之前定位过程中预存的地理位置信息来进行快速定位，下面同样以所述定位方法应用于待定位终端为例，来详细介绍二次定位的具体实现步骤：
二次定位同样包括初次定位中的步骤S201、步骤S202、步骤S203和步骤S204，其中，步骤S204中根据所述待定位终端的地磁信息组，获取所述待定位终端所处的地理位置信息，如图3所示，包括：
步骤S301，发送所述待定位终端的小区识别码至定位服务器；
步骤S302，接收所述定位服务器返回的与所述待定位终端的小区识别码对应的位置信息集合，所述位置信息集合包括至少一个地磁信息组和与所述至少一个地磁信息组对应的至少一个地理位置信息；
步骤S303，从所述至少一个地磁信息组中确定出与所述待定位终端的地磁信息组匹配的匹配地磁信息组；
步骤S304，确定所述至少一个地理位置信息中，与所述匹配地磁信息组对应的地理位置信息为所述待定位终端所处的地理位置信息。
在具体实施过程中，所述匹配地磁信息组可以为与所述待定位终端的地磁信息组相同的地磁信息组，也可以为与所述待定位终端的地磁信息组的匹配度高于阈值的地磁信息组，在本实施例中不作限制。
例如，当待定位终端Ma的CELL ID为c1982，地磁信息组为{x0′,y0′,z0′,acc0′},{x1′,y1′,z1′,acc1′},{x2′,y2′,z2′,acc2′}时：
待定位终端将CELL ID发送至定位服务器。
定位服务器接收到CELL ID后，解析出CELL ID为c1982，并从存储单元中读取出与c1982对应存储的所有地磁信息组，及对应的地理位置信息，组成位置信息集合，并将所述位置信息集合发送至待定位终端，所述位置信息集合如表2所示：
Figure PCTCN2015086938-appb-000001
Figure PCTCN2015086938-appb-000002
表2
接下来，待定位终端从接收到的地磁信息组中确定出与所述待定位终端的地磁信息组匹配的匹配地磁信息组。
以所述地磁信息组为根据地磁信息的垂直分量值，筛选出的与待定位终端基本处于同一水平面的邻近终端的地磁信息组成的地磁信息组为例，具体匹配方式如下：
用待定位终端的地磁信息组中的X方向分量值、Y方向分量值分别乘以地磁精度值获得权重精度后的待定位终端的地磁信息组：
{x0′*acc0′,y0′*acc0′,z0′},{x1′*acc1′,y1′*acc1′,z1′*acc1′},{x2′*acc2′,y2′*acc2′,z2′}
同样用位置信息集合中的每个地磁信息组的X方向分量值、Y方向分量值分别乘以对应的地磁精度值，获得权重精度后的位置信息集合的地磁信息组如下：
对表2中第一组权重精度后的地磁信息组：
{x0*acc0,y0*acc0,z0}，{x1*acc1,y1*acc1,z1},{x2*acc2,y2*acc2,z2}，{x3*acc3,y3*acc3,z3}
对表2中第二组权重精度后的地磁信息组：
{xa*acca,ya*acca,za}，{xb*accb,yb*accb,zb},{xc*accc,yc*accc,zc}
再根据权重精度后的地磁信息，分别计算每组地磁信息组的匹配度，具体如下：
表2中第一组地磁信息组与所述待定位终端的地磁信息组的匹配度
Figure PCTCN2015086938-appb-000003
Figure PCTCN2015086938-appb-000004
表2中第二组地磁信息组与所述待定位终端的地磁信息组的匹配度
Figure PCTCN2015086938-appb-000005
Figure PCTCN2015086938-appb-000006
假设P1等于0.8，P2等于0.72，因为P1大于P2，确认表2中匹配度较高的第一组地磁信息组为匹配地磁信息组，从而确定第一组地磁信息组对应的地理位置信息，即北京第一大道10号的第一面馆为所述待定位终端所处的地理位置信息。
在具体实施过程中，在二次定位时，也可以是待定位终端将地磁信息组发送给定位服务器，由定位服务器侧来进行匹配出匹配地磁信息组和确定匹配地磁信息组对应的地理位置信息，此时，待定位终端获取所述待定位终端所处的地理位置信息的具体步骤如下：
发送所述待定位终端的小区识别码和所述待定位终端的地磁信息组至定位服务器；
接收所述定位服务器返回的与所述待定位终端的地磁信息组匹配的匹配地磁信息组对应的地理位置信息；
确定所述匹配地磁信息组对应的地理位置信息为所述待定位终端所处的地理位置信息。
具体来讲，定位服务器侧匹配出匹配地磁信息组的方法与前述待定位终端匹配出匹配地磁信息组的方法相同，在此不再累述。
当然，所述定位方法也可以应用于定位服务器，当所述定位方法应用于定位服务器时，具体步骤如下：
首先，执行步骤S201获取待定位终端的CELL ID。
在具体实施过程中，定位服务器可以接收待定位终端发送的CELL ID及定位请求。
接下来，执行步骤S202，根据所述待定位终端的CELL ID，确定出所述待定位终端的至少一个邻近终端，所述至少一个邻近终端中每个邻近终端的CELL ID与所述待定位终端的CELL ID相同；
在具体实施过程中，定位服务器可以与所述待定位终端所处的小区基站通信来确定所述至少一个邻近终端，也可以从存储单元中读取预存的CELL ID与终端的对应关系来确定所述至少一个邻近终端。
再下来，执行步骤S203，获取所述至少一个邻近终端中每个邻近终端所处位置的地磁信息和所述待定位终端所处位置的地磁信息，以生成所述待定位终端的地磁信息组；
在具体实施过程中，定位服务器可以与所述至少一个邻近终端和所述待定位终端通信来获取地磁信息组，也可以通过所述待定位终端来与所述至少一个邻近终端通信获取地磁信息组。
然后，执行步骤S204，根据所述待定位终端的地磁信息组，获取所述待定位终端所处的地理位置信息。
在初次定位时，定位服务器可以先在实测的地磁信息图中确定出与待定位终端的地磁信息组匹配的区域，再根据大地坐标系获取该区域的大地坐标和地理位置信息。
在二次定位时，定位服务器可以从预存的位置信息集合中查找出与所述待定位终端的地磁信息组匹配的匹配地磁信息组，再确定所述匹配地磁信息组对应的地理位置信息为所述待定位终端所处的地理位置信息。
由于，所述定位方法应用于定位服务器时的定位原理与前述的所述定位方法应用于待定位终端时的定位原理基本相同，在此就不再累述。
在具体实施过程中，当上述初次定位或二次定位获得的地理位置信息不能满足用户的定位精度要求时，可以输出定位地图以供用户自行准确定位。即在通过步骤S204获取所述待定位终端所处的地理位置信息后：
获取所述待定位终端所处的地理位置信息的定位精度；
判断所述定位精度是否满足预设精度要求；
当所述定位精度不满足所述预设精度要求时，显示设定的定位地图；
检测到所述定位地图上被触发确定一定位点的确定操作；
基于所述确定操作，获取所述定位点的精确地理位置信息，作为所述待定位终端所处的地理位置信息。
具体来讲，在定位精度不能满足预设精度要求时，才输出定位地图供用户自行定位，不仅能避免每次都需用户自行定位导致的操作步骤复杂，还能保证定位的精确度。
具体来讲，本申请提供的定位方法，先使用CELL ID来获取一个较大的定位范围，再使用待定位终端及其邻近终端所处位置的地磁信息来进行精确定位，一方面能够弥补WIFI、蓝牙等有源信号定位方法不稳定的缺陷，提高定位稳定性；另一方面弥补了CELL ID定位方法精度低的缺陷，提高了定位精度；再一方面使用待定位终端及其邻近终端所处位置的地磁信息来协同定位，避免了使用单一地磁信息定位存在的定位不准确的缺陷，提高了定位准确度，实现了兼顾定位稳定性、精确度和准确度的技术效果。
下面，以实施例一中的定位方法应用于待定位终端时，站在图1所示系统中的定位服务器的角度对上述方法进行介绍。
实施例二：
在本实施例中，将分初次定位和二次定位两种情况，从定位服务器侧对实施例一中提供的方法应用于待定位终端的情况进行描述。
对于初次定位，请参考图4，图4为本发明实施例中初次定位时定位服务器侧的处理流程图。
该定位方法包括：
步骤S401，接收待定位终端发送的地磁信息组，所述地磁信息组包括邻近终端所处位置的地磁信息和所述待定位终端所处位置的地磁信息，其中，所述邻近终端为小区识别码与所述待定位终端的小区识别码相同的终端；
步骤S402，根据所述地磁信息组，确定与所述地磁信息组对应的地理位置信息；
步骤S403，发送所述地理位置信息至所述待定位终端。
在具体实施过程中，所述待定位终端可以为手机、平板电脑或智能手表等终端，在本实施例中不作限制。
在具体实施过程中，步骤S402中根据所述地磁信息组，确定与所述地磁信息组对应的地理位置信息可以为：定位服务器先在实测的地磁信息图中确定出与待定位终端的地磁信息组匹配的区域，再根据大地坐标系获取该区域的大地坐标和地理位置信息。
对于二次定位，请参考图5，图5为本发明实施例中二次定位时定位服务器侧的处理流程图一。
该定位方法包括：
步骤S501，接收待定位终端发送的小区识别码；
步骤S502，根据所述小区识别码，从预存的地磁数据库中，确定与所述小区识别码对应的位置信息集合，所述位置信息集合包括至少一个地磁信息组和与所述至少一个地磁信息组对应的至少一个地理位置信息；
步骤S503，发送所述位置信息集合至所述待定位终端。
在具体实施过程中，所述待定位终端可以为手机、平板电脑或智能手表等终端，在本实施例中不作限制。
在具体实施过程中，步骤S502中根据所述CELL ID，从预存的地磁数据库中，确定与所述小区识别码对应的位置信息集合可以为：定位服务器接收到CELL ID后，解析出CELL ID的值，并从存储单元中读取出与该CELL ID的值对应存储的所有地磁信息组，及对应的地理位置信息，组成位置信息集合。
在具体实施过程中，在二次定位时，也可以是待定位终端将地磁信息组发送给定位服务器，由定位服务器侧来进行匹配出匹配地磁信息组和确定匹配地磁信息组对应的地理位置信息，请参考图6，图6为本发明实施例中二次定位时定位服务器侧的处理流程图二。
此时，定位服务器侧二次定位的具体步骤如下：

实施例三
在本实施例中，提供了一种定位方法，
在介绍本实施例之前，先介绍本实施例中定位方法所对应的系统，如图7所示，图7为一种用于实施本实施例提供的定位方法的系统，该系统包括：定 位服务器、待定位终端和至少一个有源信号设备。
如图8所示，该定位方法包括：
步骤S801，获取有源信号设备广播的所述有源信号设备所处位置的地磁信息和所述有源信号设备的设备标识；
步骤S802，当所述地磁信息符合预设条件时，发送所述设备标识至定位服务器；
步骤S803,接收所述定位服务器基于所述设备标识和预存的设备标识与地理位置信息的对应关系，返回的与所述设备标识对应的地理位置信息。
在具体实施过程中，本实施例提供的定位方法可以应用于手机、平板电脑或智能手表等待定位终端，在本实施例中不作限制。
在具体实施过程中，所述有源信号设备可以为使用蓝牙技术进行广播的蓝牙设备，也可以为使用WIFI技术进行广播的WIFI设备，在本实施例中不作限制。
下面对本实施例提供的方法进行说明：
首先，执行步骤S801获取有源信号设备广播的所述有源信号设备所处位置的地磁信息和所述有源信号设备的设备标识。
具体来讲，待定位终端在接收到定位请求后，通过WIFI或蓝牙搜索接收周边有源信号设备广播的信令；并对接收到的信令进行解析，获取所述有源信号设备的地磁信息和所述有源信号设备的设备标识。
接下来，执行步骤步骤S802，即当所述地磁信息符合预设条件时，发送所述设备标识至定位服务器；
在具体实施过程中，所述地磁信息符合预设条件，至少可以有所述地磁信息符合区域限制和所述地磁信息与历史地磁信息匹配两种，下面分别进行说明：
第一种，所述地磁信息符合区域限制。
即所述当所述地磁信息符合预设条件时，发送所述设备标识至定位服务器，具体为：
判断所述地磁信息中的分量值是否处于预设数值范围；
当所述地磁信息中的分量值是否处于预设数值范围时，发送所述设备标识至定位服务器。
具体来讲，即先判断所述地磁信息中的X方向分量值、Y方向分量值、Z方向分量值和地磁精度值中的任意一个或多个均处于预设数值范围，从而确定该地磁信息在大地坐标系中所对应的区域是否在一个预设的区域内。
当确定该地磁信息在大地坐标系中所对应的区域在一个预设的区域内时，再发送所述设备标识至定位服务器。
在具体实施过程中，所述预设的区域可以为：根据CELL ID等定位技术确定的初始区域。
具体来讲，在地磁信息中的分量值是否处于预设数值范围时，才将设备标识发送至定位服务器来进行定位，能保证用于定位地磁信息符合一定的定位精度要求，提高定位精度。
第二种，所述地磁信息与历史地磁信息匹配。
即所述当所述地磁信息符合预设条件时，发送所述设备标识至定位服务器，具体为：
判断所述地磁信息是否与预存的与所述设备标识对应的历史地磁信息匹配；
当所述地磁信息与所述历史地磁信息匹配时，发送所述设备标识至定位服务器。
在具体实施过程中，判断所述地磁信息是否与所述历史地磁信息匹配的方法可以为：判断所述地磁信息与所述历史地磁信息的匹配度是否大于预设阈值。
具体的匹配度的计算方法可以与实施例一提供的匹配度的计算方法相同，在此不再累述。
具体来讲，在所述地磁信息与所述历史地磁信息匹配时，才将设备标识发送至定位服务器来进行定位，筛除位置发生较大变动的有源信号设备发送的地磁信息，能保证用于定位地磁信息符合一定的准确度要求，提高定位准确度。
下面站在图7所示系统中的有源信号设备的角度对上述方法进行介绍。

在具体实施过程中，所述有源信号设备所处位置的地磁信息可以通过设置在所述有源信号设备上的地磁感应器感应获得。
下面，结合图7从有源信号设备、待定位终端和定位服务器的交互的角度来说明实施例三和实施例四中定位方法的详细步骤:
有源信号设备调用地磁传感器获取地磁数据；
有源信号设备以时间戳和地磁数据进行成对存储；
有源信号设备广播当前获取的地磁数据、设备信息设备ID、信令强度等；
待定位终端收到定位请求后，获取接收到有源信号设备广播的信令；
待定位终端定位解析信令消息，分别对消息中的每个设备的地磁记录进行状态识别，依次根据XYZ轴的地磁值识别出地磁数据发生较大变化的设备标识和地磁数据变化在允许的范围内的设备标识；并设置识别状态后的设备标识集为查询位置设备标识集；
待定位终端发送所述查询位置设备标识集至定位服务器，请求查询位置；
定位服务器设置地磁数据发生较大变化的设备标识为失效，获取地磁数据变化在允许的范围内的设备标识对应的位置信息；
定位服务器返回所述位置信息到位置查询单元；
