Description

一种定位方法的选择、控制方法及装置
本申请要求在2014年3月13日提交中国专利局、申请号为201410093063.6、发明名称为“一种定位方法的选择、控制方法及装置”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
本申请涉及通信技术领域，尤其涉及一种定位方法的选择、控制方法及装置。
背景技术
如果用户设备(User Equipment，UE)具有全球卫星导航(Global Navigation Satellite System，GNSS)功能，例如全球定位系统(Global Positioning System，GPS)，可以直接利用GPS获得UE当前的位置，这种称为standalone GNSS定位。
由于GNSS成本高以及室内场景下GNSS信号衰落比较大，现有技术提出了基于蜂窝网络信号或者蜂窝网的辅助，获得UE的位置的方法，即定位服务(Location Service，LCS)。
LTE LCS控制面定位流程如图1所示，包括步骤：
1.移动管理实体(Mobile Management Entity，MME)收到定位服务请求，该服务请求可以是UE通过非接入层(Non Access Stratum，NAS)消息向MME发起的请求，也可以是演进分组核心(Evolved Packet Core，EPC)中的一些实体(如网关移动位置中心(Gateway Mobile Location Center，GMLC))或MME内部发起定位服务请求。
2.MME将定位服务请求发给演进的服务移动位置中心(Evolved Serving Mobile Location Center，E-SMLC)，E-SMLC根据该定位请求中携带的服务质量(Quality of Service，QoS)，例如定位的精度和时延等信息，选择合适的定位方法。
3a.E-SMLC通过LTE定位协议A(LTE Positioning Protocol Annex，LPPa)，可能触发演进基站(evolved Node B，eNB)相关的定位过程，例如获取定位所需的辅助数据、或者定位所需的测量；
3b.E-SMLC通过LTE定位协议(LTE Positioning Protocol，LPP)可能触发UE相关的定位过程，例如获取位置估计、传输定位所需的辅助数据、或者获取定位所需的测量；
4.E-SMLC给MME发送定位服务响应，当中包括了一些所需的结果，例如UE的位置、定位成功或失败的指示等；
5MME将定位服务响应返回给目标实体。
下面介绍一下控制面定位所支持的定位方法。
当前LTE LCS控制面定位所支持的定位方法有：
一、基于小区标识(Cell ID)，通过已知的服务小区地理信息，结合其他测量信息，计算出UE的位置，例如时间提前量(Time Advance，TA)+到达角(Angle of Arrival，AOA)方法；
二、UE同时监听多个基站的导频信号，获得基站间信号到达的时间差，通过两个以上的双曲线方程确定UE的位置，例如观测到达时间差(Observed Time Difference of Arrival，OTDOA)、上行到达时间差(Uplink Time Difference Of Arrival，UTDOA)方法；
三、网络辅助的全球卫星导航系统定位方法(A-GNSS)。其中，全球卫星导航系统包括GPS、Galileo以及其他可能的定位系统。A-GNSS方法将UE的工作简化，由网络侧的定位计算中心与UE相互配合完成定位工作。例如网络侧可以根据UE的初步位置，估计出该位置上空的卫星运行情况，例如星历(ephemeris)、历书(almanac)和差分校准信息等，并发送给UE。UE可以将其作为先验知识进行优化搜索和定位过程，从而起到减少搜索时间、降低搜索信号电平需求等效果，提高了定位性能。
随着智能手机的普及，室内定位的商机逐渐体现，但同时面临着挑战，例如当前使用广泛的GPS定位，由于无法接收到卫星信号，无法进行成功的室内定位；使用蜂窝网信号进行室内定位，由于室内NLOS环境，也导致定位精度降低。因此，LTE控制面定位中，可能在已有的几种定位方法基础上，再引入其他方式的定位，例如：
基于wlan信号的定位。当前运营商通过部署wlan，实现蜂窝网业务的分流，因此可以利用已部署的wlan，实现更精确的室内定位；
利用伪卫星(Pseudo-Satellite或Pseudolite，缩写为PL)定位，由于室内定位需求，在一些室内布设于地面上发射某种定位信号的发射器，通常都是发射类似于GPS的信号，这样UE可以通过接收伪卫星信号，进行室内定位。
综上所述，LTE控制面定位支持多种定位方法，且后续随着技术的演进，所支持的定位方法可能会越来越多。UE移动过程中，周围环境不断发生变化，导致UE所能使用的合适的定位方法也发生变化。比如从室外移动到商场室内，商场内部除了蜂窝基站外，还有wlan用于分流，此时UE在室外所使用的A-GNSS定位方法不可用，而需要使用wlan进行定位；或者，UE从一个只有蜂窝基站部署的室内环境移动到部署了伪卫星的室内环境，为了获得更精确的室内定位结果，UE需要由使用蜂窝基站定位转换到伪卫星的定位方法。控制面定位时，UE如何实现无缝的定位转换，当前还没有可实现的方式。

具体实施方式
本申请实施例提供了一种定位方法的选择、控制方法及装置，用以实现UE对定位方法的选择，从而可以实现无缝的定位转换。
当前定位方法多种多样，在UE的移动过程中，由于环境发生变化，例如室外移动到室内，由wifi部署的室内移动到只有基站部署的室内等，UE所能使用的定位方法发生变化。本申请实施例提供一种方法，用于实现控制面定位架构下无缝的定位转换。主要通过定位服务器向UE发送定位方法之间转换的辅助数据；UE根据所收到的定位方法之间转换的辅助数据，选择合适的定位方法并将相应的定位测量结果发送给网络侧，供网络侧计算出满足QoS要求的UE位置信息。
其中，所述辅助数据包括：UE当前支持的每种定位方法所对应的优先级和/或定位条件；
其中，所述优先级为用于指示UE进行定位方法选择时的优先级，所述定位条件为用 于指示UE判断按照优先级选择的定位方法是否满足对应的定位条件，当满足定位条件时确定选择该定位方法，否则继续按照优先级选择另一定位方法。
所述的定位条件包括定位门限，例如：对于OTDOA定位方法，定位条件包括预设定位门限为3，则UE使用OTDOA方法进行定位且获得三个定位测量结果时，可认为满足OTDOA方法对应的定位条件。
所述的定位条件还可以包括其他参数，例如：对于wlan定位方法，定位条件包括预设定位门限为2，以及所监听的wlan对应的SSID为预设的特定SSID，则UE监听到2个广播特定SSID的wlan信号，可认为满足wlan定位方法对应的定位条件。
其中，定位服务器向UE发送的定位方法之间转换的辅助数据是根据定位服务请求确定的。较佳地，定位服务器根据定位服务请求，确定用于指示UE选择定位方法的辅助数据(即定位方法之间转换的辅助数据)，包括：
定位服务器根据定位服务请求中所携带的QoS参数、当前UE的服务小区或者位置信息，以及UE和网络侧的定位能力，确定用于指示UE选择定位方法的辅助数据。
较佳地，定位服务器当收到位置更新消息时，根据UE服务小区的更新，以及之前对UE的定位结果，决定是否更新所述辅助数据并发送给所述UE。
当所述辅助数据包括UE当前支持的每种定位方法所对应的优先级和定位条件时，UE根据所述辅助数据进行定位方法的选择，包括：
UE按照优先级由高到低顺序选择定位方法，并判断该选择的定位方法是否满足该定位方法所对应的定位条件，如果是，则采用所选择的定位方法进行定位测量并上报测量结果，否则，按照优先级由高到低顺序依次选择定位方法并判断该选择的定位方法是否满足该定位方法所对应的定位条件，直到所选择的定位方法满足对应的定位条件，并采用最终选择的定位方法进行定位测量并上报测量结果。
或者，当所述辅助数据包括UE当前支持的每种定位方法所对应的优先级和定位条件时，UE根据所述辅助数据进行定位方法的选择，包括：
UE判断上次选择的定位方法是否仍然满足对应的定位条件；
如果是，则继续采用上次选择的定位方法进行定位测量并上报测量结果，并且，UE判断是否存在优先级比上次选择的定位方法的优先级高、并且满足对应的定位条件的定位方法，若存在则利用该定位方法进行定位测量并上报测量结果；
如果上次选择的定位方法不满足对应的定位条件和/或不存在优先级比上次选择的定位方法的优先级高、并且满足对应的定位条件的定位方法，判断是否存在优先级小于或等于上次选择的定位方法的优先级、并且满足对应的定位条件的定位方法，若存在则利用该定位方法进行定位测量并上报测量结果。
下面给出几个具体实施例的举例说明。
实施例1：定位服务器设置辅助数据。
如图2所示，MME收到UE或GMLC或MME内部发起的定位服务请求，向E-SMLC发送定位服务请求(当前LTE定位的已有过程)；
E-SMLC根据定位服务请求中所携带的定位QoS参数(如定位精度、响应时间等)、当前UE的服务小区或者位置信息，结合UE和网络侧的定位能力,确定UE当前可能使用的定位方法、及其相应的优先级、定位条件等，并通过LPP消息发送给UE。
例如，E-SMLC接收到定位服务请求，当前包含的定位精度要求为100米，根据当前UE的服务小区或者位置信息，E-SMLC可以确定UE周围可能有wlan覆盖，且处于室内，因此E-SMLC再结合UE和网络侧的定位能力，生成用于指示UE选择定位方法的辅助数据，包括：
wlan定位方法，优先级3，定位门限为2，即UE监听到两个的wlan信号即可认为定位条件满足，或者定位条件中进一步包括所监听的wlan对应的特定SSID，即当UE监听到两个广播该特定SSID的wlan信号即可认为定位条件满足；
OTDOA定位方法，优先级2，定位门限为3，即UE使用OTDOA定位且获得三个定位测量结果可认为定位条件满足；
RF定位方法，优先级1，无定位条件，即只要获得RF结果，无论是蜂窝网还是wlan，即认为满足定位条件。
需要说明的是，优先级高低按照数字排序决定，优先级0为最低优先级，另外，所提供的定位方法可能只是UE所支持的定位方法和网络侧所支持的定位方法的一个子集，并不用提供所有当前所能支持的定位方法的优先级。对于未能提供优先级的定位方法，且需要依赖于LTE控制面定位，则UE可认为该定位方法优先级最低，为0；对于不需要依赖于LTE控制面定位的方法，例如独立GPS(standalone GPS)定位，其使用的优先级与LTE控制面定位中的优先级不属于本申请的范围，具体可取决于UE实现。
随着UE的移动，UE进入到另外一个服务小区，此时由UE触发位置更新，并通过LPP消息发送给E-SMLC，该消息中携带当前的服务小区。E-SMLC根据服务小区的更新，以及之前对UE的定位结果，决定是否需要更新用于指示UE选择定位方法的辅助数据。例如E-SMLC根据服务小区更新，判断当前UE可能进入到室外，那么E-SMLC可以生成新的用于指示UE选择定位方法的辅助数据并发送给UE，该辅助数据包括：
wlan定位方法，优先级3，定位门限为2；
GPS定位方法，优先级2，定位门限3(即UE搜索到3颗GPS信号即可认为满足定位门限)；
OTDOA定位方法，优先级1，定位门限为3；
RF定位方法，优先级0，定位门限无。
另外，位置更新也可能由MME通知给E-SMLC，例如，每次发生切换后，如果MME获得更新的UE服务小区，则触发位置更新消息，通知给E-SMLC，从而触发E-SMLC判断是否需要更新用于指示UE选择定位方法的辅助数据。
实施例2：UE按照优先级由高到低顺序尝试选择定位方法。
UE处于一个商场室内，该商场内运营商部署了蜂窝网和wlan网络，室外及商场部分地区还可能搜索到GPS信号。
步骤一：UE从E-SMLC处接收到请求位置信息消息，当中携带此次定位上报的类型为周期性上报，上报间隔为10s，上报次数无穷，同时，该消息中还携带用于指示UE选择定位方法的辅助数据，该辅助数据包括：
Wlan定位条件，优先级3，定位门限为1，定位门限中进一步包括所监听的wlan对应的SSID为CMCC，即UE监听到1个广播特定SSID的wlan信号即可认为满足定位条件；
GPS定位条件，优先级为2，定位门限为3，即UE需要接收到3个GPS信号则认为满足GPS定位方法的定位条件；
OTDOA定位条件，优先级1，定位门限为3，即UE使用OTDOA定位方法且获得三个定位测量结果可认为满足定位条件；
RF定位条件，优先级1，定位门限无，即只要获得RF结果，无论是蜂窝网还是wlan，即认为满足定位条件。
其中，请求位置信息消息可以但不仅限于是LPP消息。
步骤二：UE根据收到的请求位置信息消息，开始按照定位方法的优先级级别，由高到低的顺序不断尝试不同的定位方法，由于未检测到广播CMCC的wlan信号以及GPS信号，UE开始尝试OTDOA定位。UE按照现有的定位流程，获得OTDOA所需的辅助数据及测量间隔(gap)，完成定位测量，并将定位测量结果上报给E-SMLC。
步骤三：周期性定位定时器超时后，UE再次启动定位测量。此时UE仍然是按照定位方法的优先级级别，由高到低的顺序不断尝试不同的定位方法，而此时UE搜索到广播CMCC的wlan信号，则满足wlan的定位门限，UE选择wlan定位，并将wlan定位测量结果上报给E-SMLC，供其进行UE位置计算。
由于是周期性定位，UE不停的重复步骤三的过程，直到E-SMLC停止定位为止。
实施例3、UE同时尝试上次定位方法及高优先级定位方法。
UE处于一个商场室内，该商场内运营商部署了蜂窝网、wlan网络和用于室内定位的伪卫星定位。
步骤一：UE从E-SMLC处接收到请求位置信息消息，当中携带此次定位上报的类型为周期性上报，上报间隔为10s(现有控制面定位过程)，上报次数无穷，同时，该消息中还携带用于指示UE选择定位方法的辅助数据，包括：
伪卫星定位方法，优先级为2，定位门限为3，即UE需要接收到3个伪GPS信号则认为满足定位条件；
Wlan定位方法，优先级2，定位门限为2，定位门限中进一步包括所监听的wlan对应的SSID为CMCC，即UE监听到2个广播特定SSID的wlan信号即可认为满足定位条件；
OTDOA定位方法，优先级1，定位门限为3，即UE使用OTDOA定位方法且获得三个定位测量结果可认为满足定位条件；
RF定位方法，优先级0，定位门限无，即只要UE获得RF结果，无论是蜂窝网还是wlan，即认为满足定位条件。
步骤二：UE根据收到的请求位置信息消息，开始尝试定位；由于没有上次定位方法，则可认为上次定位优先级为最低，开始按照定位方法的优先级的级别由高到低的顺序，不断尝试不同的定位方法，由于未检测到3个伪GPS信号，则UE尝试wlan定位，此时UE监听到2个广播CMCC的wlan信号，认为满足wlan定位方法的定位条件，则将wlan定位测量结果上报给E-SMLC，供其进行UE位置计算；
步骤三：周期性定位定时器超时后，UE再次启动定位测量。由于上次定位方法为wlan定位，则UE尝试wlan定位方法，此时UE搜索到2个广播CMCC的wlan信号，满足wlan定位方法对应的定位条件，则UE将wlan定位测量结果发送给网络侧；并且，UE尝试比wlan优先级高的其他定位方法，即伪GPS信号定位，此时如果UE搜索到3个伪GPS信号，满足伪GPS定位方法对应的定位条件，则UE将获得的伪GPS定位测量结果发送给网络侧，供网络侧计算出更合适的UE位置信息；
如果wlan定位和伪GPS定位均不满足相应的定位条件，则UE按照优先级由高到低的顺序，尝试OTDOA定位和RF定位。
由于是周期性定位，UE不停的重复步骤三的过程，直到E-SMLC停止定位为止。
