本发明实施例提供了一种定位方法、装置和***、定位信号确定方法及
终端，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
在本例中，提出了一种定位方法和定位信号确定方法，其中，定位信号是携带有时间参数的信号，并对计算到达时间差(TDOA)方式进行了改进，从而可以误差率较小地确定终端的位置。
上述终端可以是移动终端，例如：手机、平板电脑等存在智能模块的终端设备，也可以是便携式的设备，例如：智能手表等都可以作为终端。
如图1所示，在本例中，提供了一种定位方法，可以包括以下步骤：
步骤101：获取待定位终端的定位信号，其中，所述定位信号包括：时间参数；
上述时间参数可以是平均到达时间差，相对于当前的通过达到时间差进行定位的方式，通过平均达到时间差进行定位的方式精度更高。
上述平均达到时间差可以按照以下方式确定，如图2所示：
S1:终端向基站发出获取到达时间差的触发指令；
S2：终端接收多个基站返回的到达时间差；
S3：终端通过多个基站返回的到达时间差，确定平均到达时间差，并将所述平均到达时间差作为定位信号，可选地，终端可以对多个基站按照3个基站为一组的方式进行组合；从组合结果中，确定出两个到达时间差最小的一组基站所对应的两个到达时间差；将确定出的两个到达时间差作为所述平均到达时间差。
即，终端可以判断接收到信息的基站的数量，并将每个基站的时间测量值TDOA值进行保存，考虑到每个TDOA估值精度相差很大，因此如果直接基于某个基站的TDOA值进行定位，会产生较大的定位误差，因此，在本例中，可以对N个基站进行排列组合，从N个基站中找出3个基站，将计算出的最小的两个TDOA值，赋值到平均到达时间差。
其中，TDOA(到达时间差)是通过检测信号到达两个基站的时间差，而不是到达的绝对时间来确定移动台的位置，降低了时间同步要求。采用三个不同的基站，将其中一个基站为作为标准基站，分别计算检测信号达到标
准基站和两个非标准基站的时间差，可以测到两个TDOA，移动站位于两个TDOA决定的双曲线的交点上。
在确定了定位信号(例如：平均到达时间差)之后，可以通过将定位信号代入预设公式的方式计算得到待定位终端的位置，也可以是预置了一张定位信号列表数据库，在确定了定位信号之后，可以直接根据定位信号，在预设的定位信号列表数据库中进行查询，将查询结果作为待定位终端的位置。
考虑到有时候终端并未支持所有类型的数据，有些数据类型基站侧是支持的，而终端侧是不支持的，为了解决该问题，终端可以告知基站自身所支持的数据类型，这样在基站向终端返回数据的时候，就选择终端侧可以支持的数据类型返回即可，从而避免数据不兼容的问题。在一个实施方式中，终端在向基站发出获取到达时间差的触发指令之后，接收多个基站返回的到达时间差之前，可以向基站发送类型指示信息，其中，类型指示信息用于指示终端支持的数据类型；终端接收基站返回的类型确认信息；相应的，终端接收多个基站返回的到达时间差是所述多个基站按照与所述类型指示信息中所指示的数据类型返回的。
例如，基站支持的数据类型为：类型1、类型2、类型3、类型4和类型5，而终端仅支持类型1和类型2，那么在上述这种数据交互之后，基站就知道终端是仅支持类型1和类型2的，基站在向终端返回数据的时候，也就可以向终端返回类型1的数据，或者返回类型2的数据。
步骤102：根据所述定位信号对所述待定位终端进行定位。
即，终端在确定出定位信号之后，可以将定位信号发送至定位装置，以使得定位装置可以根据该定位信号确定出终端的位置。
在具体实现的时候，定位装置可以是内置在所述终端中的，也可以是与终端分开设置的，例如可以外接在终端上，或者是通过蓝牙或者无线的方式与终端相连，设置在基站上的，本申请对定位装置的设置位置不作限定。
本发明实施例中还提供了一种定位***，如下面的实施例所述。由于定位***解决问题的原理与定位方法相似，因此定位***的实施可以参见定位方法的实施，重复之处不再赘述。以下所使用的，术语“单元”或者“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较

其中，上述的时间参数可以包括：平均到达时间差值。
在一个实施方式中，确定模块303可以包括：组合单元，设置为对所述多个基站按照3个基站为一组的方式进行组合；选择单元，设置为从组合结果中，确定出两个到达时间差最小的一组基站所对应的两个到达时间差；确定单元，设置为将确定出的两个到达时间差作为所述平均到达时间差。
在一个实施方式中，上述终端中还可以包括：第二发送模块，设置为在向基站发出获取到达时间差的触发指令之后，接收多个基站返回的到达时间差之前，向基站发送类型指示信息，其中，所述类型指示信息用于指示所述终端支持的数据类型；第二接收模块，设置为接收所述基站返回的类型确认信息；其中，接收的多个基站返回的到达时间差是所述多个基站按照与所述类型指示信息中所指示的数据类型返回的。

如图3所示，定位装置位于终端中，如图4所示，定位装置与终端分开设置，对于定位装置具体设置的位置可以根据实际需要设定，具体采用硬件方式还是软件方式设置都可以，本申请对此不做限定。
下面结合一具体实施例对上述定位方法和定位***进行说明，然而值得注意的是，该具体实施例仅是为了更好地说明本发明，并不构成对本发明的不当限定。
在本例中，提供了一种基于时间测量的GPS定位装置，可以包括如下几个模块：
1)获取模块，接收定位信号确认信息，其中，定位信号确认信息用于确定移动终端支持获取的定位信号的时间参数类型；
2)发送模块，向移动终端发送定位信号配置信息和定位信号确认信息，其中，定位信号配置信息用以表示对定位信号进行测量的时间参数类型，定位信号确认信息用以确认移动终端支持获取定位信号的时间参数类型的信息。
3)接收模块，接收移动终端发送的定位捕获信息，其中，定位捕获信息即TDOA值(对应上文中的定位信号)。
4)确定模块，根据定位捕获信息(即用于定位的时间参数)确定移动终端的位置信息。
在本例中，即通过捕获的时间参数作为定位信号进行终端定位，可以误差率较小地确定移动终端的位置，进而提高了对移动终端定位的精确度。

端，可以包括以下步骤：
步骤401：移动终端获取定位信号；
该定位信号可以是平均到达时间差，即平均TDOA。可选地，TDOA可以按照以下方式获得：将第一基站接收到的终端信号与第二个基站接收到的终端信号进行运算，从而可以得到TDOA值。上述的平均TDOA值可以按照以下方式计算得到：
S1：终端获取所在位置的基站信息，可选地，终端可以根据协议通过发送预设的指令获取基站信息；
S2：基站侧在接收到来自终端的信号之后，发起所有与终端有交互的基站的信号到达时间的测量；
S3：终端判断接收到信息的基站的数量，将每个基站的时间测量值TDOA值进行保存；
S4：由于每个TDOA估值精度相差很大，会产生较大的定位误差，因此可以对N个基站组合进行排序，找出最小的两个TDOA值对应的3个基站，将确定出的最小的两个TDOA值作为平均到达时间差；
通过该方式计算得到的信号传输的平均到达时间差，即，这个平均时间与所有确认信号的到达时间相关。
步骤402：终端将定位信号发送到GPS定位装置；
即将上述的平均TDOA发送至定位装置，以实现误差率较小地确定移动终端的位置的目的，有效提高了对移动终端定位的精确度。

步骤501：定位装置接收到定位信号；
该定位信号可以是终端计算出的平均TDOA，可选地，平均TDOA可以是根据多个网络节点载波上传输的信号确定的，例如：根据基站的一个或多个载波上传输的信号确定。
步骤502：根据定位信号确定移动终端的具***置。
可以按照以下两种方式，确定移动终端的位置：
方式1：根据定位信号，通过公式计算以获得移动终端的位置，从而确定移动终端的位置信息。
方式2：根据定位信号，通过对定位信号列表数据库的查询，获得移动终端的位置，从而确定移动终端的位置信息，其中，该定位信号列表可以是根据经验数据建立的列表，可以预置在定位装置中。
为了更清楚地说明本发明，在本例中，还提供了终端、基站和定位装置进行数据交互以建立连接的流程，该流程主要是为了说明三者之间在定位前的准备状态时候的数据信息交互，可以包括：
步骤1：定位装置向基站发送定位信号确认信息，其中，定位信号确认信息可以用于确认移动终端支持获取定位信号的时间参数类型；
步骤2：基站向移动终端发送定位信号确认信息，用于确认基站已收到定位信号确认信息；
步骤3：移动终端向基站发送定位信号支持信息，其中，定位信号支持信息用于指示移动终端所支持的获取定位信号的时间参数的类型，例如：数据类型1和数据类型2；
步骤4：基站向定位装置发送定位信号支持信息，即，基站将数据类型1和数据类型2发送至定位装置，表明已知晓终端所支持的数据类型；
步骤5：定位装置向基站发送定位信号配置信息，其中，定位信号配置信息用于告知基站定位信号进行测量的时间参数类型和定位信号的种类，其中，定位信号种类可以是基站的一个或多个载波上传输的定位信号，定位信号的时间参数类型可以是计算得到的平均TDOA值；
步骤6：基站向移动终端发送定位信号配置信息；
步骤7：移动终端根据定位信号配置信息，获取定位信号配置信息指示的定位信号信息；
步骤8：移动终端向基站发送定位信号信息，并接收基站的反馈，从而计算得到平均TDOA值，并将平均TDOA值发送至定位装置，以确定移动终端的位置。
通过计算平均TDOA值的方式确定移动终端的位置，从而可以误差率较小地确定移动终端的位置，有效提高了移动终端定位的精确度。上述的定位装置可以设置在移动终端中，也可以考虑将移动终端和定位装置分开设置，该定位装置也可以集成在基站中，也可以独立设置，该定位装置可以采用软件和/或硬件的方式来实现。
