Description

移动终端定位测量处理方法及装置
技术领域
本发明实施例涉及终端定位技术, 尤其涉及一种移动终端定位测量处理 方法及装置。 背景技术
定位技术是为了确定终端的地理位置而采用的技术, 可以利用无线通信 网络的资源来直接或者间接地得到终端的位置信息。 在长期演进系统 (Long Term Evolution, 简称 LTE) 中采用的标准终端定位的方式有如: 网络辅助的 全球导航卫星系统 (Global Navigation Satellite System, 简称 GNSS ) 定位, 下行定位如观察到达时间差 (Observed Time Difference of Arrival, 简称 OTDOA) 定位方法, 上行到达时间差 (Uplink Time Difference of Arrival, 简 称 UTDOA) 定位方法等。
在 LTE中, OTDOA定位方法实现原理如下, 在网络侧定位服务器为基 站和终端指定定位参考信号(Positioning Reference Signal, 简称 PRS )的发送 和接收配置之后, 基站下行发送 PRS。 终端接收到来自多个基站的 PRS , 并 识别每个 PRS的首达径位置,可以得到不同基站之间的 PRS到达时间差 (即 参考信号到达时间差 (reference signal time difference, 简称 RSTD) ) , 并将 其上报至定位服务器。 定位服务器通过终端接收不同基站的参考信号到达时 间差, 可以映射成终端与不同基站之间的距离差, 通过双曲线模型数学计算, 定位服务器就可以得到终端的准确位置。
现有的 OTDOA中终端需要进行对于来自不同基站的 PRS的 RSTD测量, 如果当前终端的工作频点或者载波与 PRS的载波不一致, 则当终端需要测量 此载波上面的 PRS时, 就需要将终端的射频链进行调整。 图 1为现有技术中 定位测量时射频链调整示意图, 如图 1所示, 终端只具有一个射频链, 当终 端在频带 1上进行测量时, 射频链中心频点在频带 1的中心频点 1上, 射频 链覆盖频带 1, 当需要终端同时测量频带 1和频带 2的 PRS信号时, 就需要 将终端的射频链的中心频点从中心频点 1调整到中心频点 2, 并将射频链调 整到全部覆盖频带 1和频带 2。 如果定位测量是独立于移动性测量的测量行 为, 这就会造成双倍中断的情况, 例如, 如图 1所示, 终端定位测量完成之 后会将射频链调回频带 1的中心频点, 若此时终端又需要进行频带 2的移动 性测量, 又会将射频链进行调整, 带来二次中断。
现有技术对射频链的多次调整, 会对移动终端当前工作频点或者载波上 面的业务造成中断, 并且造成吞吐量减小。 发明内容

3300 * 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。
图 2为本发明移动终端定位测量处理方法实施例一的流程图, 本实施例 的执行主体为移动终端定位测量处理装置, 该装置可以通过软件和 /或硬件实 现。 如图 2所示, 本实施例的移动终端定位测量处理方法可以包括:
步骤 201、 接收移动终端的测量状态信息, 所述测量状态信息包括移动 终端当前使用的测量载波和 /或测量频点。
本实施例的执行主体可以是配置在定位服务器上的移动终端定位测量处 理装置, 也可以是定位服务器, 本实施例的方案可以应用于 LTE的 OTDOA 定位方法中。
例如, 定位服务器接收移动终端的测量状态信息, 所述测量状态信息可 以包括移动终端当前使用的测量载波和 /或测量频点, 在此之前定位服务器也 可以向基站或移动终端发起请求, 请求获取移动终端的测量状态信息, 测量 状态信息和测量状态信息的获取请求都可以通过 LTE 定位协议 A (LTE Positioning Protocol A, 简称 LPPa) 信令发送。
步骤 202、 根据测量状态信息为移动终端选择多个发送定位参考信号的 目标基站, 所述目标基站为应用移动终端当前使用的测量载波和 /或测量频点 发送定位参考信号的基站。
例如定位服务器根据测量状态信息获知移动终端当前使用的测量载波和 /或测量频点 f0、 fl以及 f2, 定位服务器会优先选择当前正在应用测量载波和 /或测量频点 f0、 fl 以及 f2的多个基站作为目标基站, 移动终端对各目标基 站发送的定位参考信号进行测量。此时移动终端的射频链覆盖 f0、 fl以及 f2, 不会造成对移动终端射频链的调整, 也就不会引起当前使用的测量载波和 /或 测量频点上数据传输的中断。
步骤 203、 将所选择的各目标基站的定位测量辅助信息下发给移动终端, 以供移动终端对各目标基站所发送的定位参考信号进行测量。
例如, 定位服务器将所选择的各目标基站的定位测量辅助信息发送给移 动终端, 定位测量辅助信息可以包括以下至少之一: 物理小区标识(Physical Cell Identifier, 简称 PCI) 、 测量频点、 PRS时域偏移、 和目标基站的定时, 以供移动终端对各目标基站所发送的定位参考信号进行测量。 移动终端根据 定位服务器发送的定位测量辅助信息对所指示的多个目标基站所发送的定位 参考信号进行测量,而对其他的基站所发送的定位参考信号可以不进行测量, 保证射频链不进行调整, 确保业务流畅。
定位测量辅助信息例如可以通过 LTE 定位协议 (LTE Positioning Protocol , 简称 LPP) 信令发送。
本实施例, 通过接收移动终端的测量状态信息, 所述测量状态信息包括 所述移动终端当前使用的测量载波和 /或测量频点, 并根据所述测量状态信息 为移动终端选择多个发送定位参考信号的目标基站, 所述目标基站为应用移 动终端当前使用的测量载波和 /或测量频点发送定位参考信号的基站, 将所选 择的各目标基站的定位测量辅助信息下发给移动终端, 以供移动终端对各目 标基站所发送的定位参考信号进行测量, 由于所选择的各目标基站为应用移 动终端当前使用的测量载波和 /或测量频点发送定位参考信号的基站, 移动终 端可以在当前使用的测量载波和 /或测量频点上进行测量, 无需调整到其他测 量载波和 /或测量频点上进行测量, 避免了对射频链的多次调整, 实现了移动 终端当前使用的测量载波和 /或测量频点上面的业务持续进行, 从而提高了吞 吐量。
下面采用几个具体的实施例, 对图 1所示方法实施例的技术方案进行详 细说明。
在本发明移动终端定位测量处理方法实施例二中, 在图 1所示方法实施 例的基础上, 所述测量状态信息还可以包括:
移动终端的射频能力信息和 /或当前射频链的空闲状态。
其中, 移动终端的射频能力信息可以是移动终端支持的射频链的个数, 当前射频链的空闲状态可以是移动终端支持的射频链的空闲状态。
优选地, 在本实施例中, 所述根据测量状态信息为移动终端选择多个发 送定位参考信号的目标基站, 还可以包括如下几种情况至少之一: 第一种情况:
若根据所述射频能力信息获知所述移动终端仅支持一个射频链, 则所选 择的所述目标基站为应用所述移动终端当前使用的测量载波和 /或测量频点 发送定位参考信号的基站。
例如定位服务器根据所述射频能力信息获知到移动终端只支持一个射频 链, 而且根据移动终端当前使用的测量载波和 /或测量频点获知到当前射频链 覆盖当前使用的测量频点, 因此定位服务器会优先选择在当前使用的测量频 点中的频点发送 PRS的基站作为目标基站, 以使移动终端对各目标基站发送 的 PRS进行测量。 又例如移动终端当前使用的测量频点所在的频带有频带 1 和频带 2, 当前移动终端只支持一个射频链, 因此定位服务器会优先选择在 频带 1和频带 2上的频点上发送 PRS的基站作为目标基站。 定位服务器将所 选择的各目标基站的定位测量辅助信息下发给移动终端, 移动终端对各目标 基站发送的 PRS进行测量, 这样就不会对原有频点上的数据传输造成中断。
第二种情况:
若根据所述射频能力信息获知所述移动终端支持两个射频链, 且根据所 述当前射频链的空闲状态获知其中一个射频链处于空闲状态, 则所选择的所 述目标基站为应用所述移动终端当前使用的测量载波和 /或测量频点, 以及应 用另一个测量载波和 /或测量频点发送定位参考信号的基站。
例如根据移动终端当前使用的测量载波和 /或测量频点获知到当前射频 链覆盖当前使用的测量频点, 移动终端目前使用的频带只有当前使用的测量 频点所在的频带 1, 但当前移动终端支持两个射频链, 也就是说有一个射频 链空闲, 因此定位服务器会优先选择在频带 1和除了频带 1的另一个任意频 带上的频点上发送 PRS的基站作为目标基站, 以使移动终端对各目标基站发 送的 PRS进行测量。 又例如移动终端当前使用的测量频点所在的频带有频带 1和频带 2, 当前移动终端支持两个射频链, 如果当前移动终端只用了一个射 频链来接收或传输或测量频带 1和频带 2上的信号, 那么另一个射频链状态 为空闲, 定位服务器可以根据这个射频链空闲的信息, 来选择在频带 1和 2 以及除了频带 1和 2的另一个任意频带上的频点发送 PRS的基站作为目标基 站, 以使移动终端对各目标基站发送的 PRS进行测量。
第三种情况: 若根据所述射频能力信息获知所述移动终端支持两个射频链, 且根据所 述当前射频链的空闲状态获知其中一个射频链处于空闲状态, 则所选择的所 述目标基站为应用所述移动终端当前使用的测量载波和 /或测量频点发送定 位参考信号的基站。
例如根据移动终端当前使用的测量载波和 /或测量频点获知到当前射频 链覆盖当前使用的测量频点, 移动终端目前使用的频带只有当前使用的测量 频点所在的频带 1, 但当前移动终端支持两个射频链, 也就是说有一个射频 链空闲, 因此定位服务器可以优先选择在频带 1上的频点发送 PRS的基站作 为目标基站, 以使移动终端对各目标基站发送的 PRS进行测量。 又例如移动 终端当前使用的测量频点所在的频带有频带 1和频带 2, 当前移动终端支持 两个射频链, 如果当前移动终端只用了一个射频链来接收或传输或测量频带 1和频带 2上的信号, 那么另一个射频链状态为空闲, 定位服务器可以根据 这个射频链空闲的信息, 来选择在频带 1和 2上的频点发送 PRS的基站作为 目标基站, 以使移动终端对各目标基站发送的 PRS进行测量。
第四种情况:
若根据所述射频能力信息获知所述移动终端支持两个射频链, 且根据所 述当前射频链的空闲状态获知其中一个射频链处于空闲状态, 则所选择的所 述目标基站为应用除了移动终端当前使用的测量载波和 /或测量频点之外的 一个测量载波和 /或测量频点发送定位参考信号的基站。
例如根据移动终端当前使用的测量载波和 /或测量频点获知到当前射频 链覆盖当前使用的测量频点, 移动终端目前使用的频带只有当前使用的测量 频点所在的频带 1, 但当前移动终端支持两个射频链, 也就是说有一个射频 链空闲, 因此定位服务器可以优先选择在除了频带 1 的任一个频带上的频点 上发送 PRS的基站作为目标基站,以使移动终端对各目标基站发送的 PRS进 行测量。 又例如移动终端当前使用的测量频点所在的频带有频带 1和频带 2, 当前移动终端支持两个射频链, 如果当前移动终端只用了一个射频链来接收 或传输或测量频带 1和频带 2上的信号, 那么另一个射频链状态为空闲, 定 位服务器可以根据这个射频链空闲的信息, 来选择除了频带 1和 2的任一个 频带上的频点发送 PRS的基站作为目标基站, 以使移动终端对各目标基站发 送的 PRS进行测量。 第五种情况:
若根据所述射频能力信息获知所述移动终端支持两个射频链, 且根据所 述当前射频链的空闲状态获知其中没有射频链处于空闲状态, 则所选择的所 述目标基站为应用所述移动终端当前使用的测量载波和 /或测量频点发送定 位参考信号的基站。
例如移动终端当前使用的测量频点所在的频带有频带 1和频带 2, 当前 移动终端支持两个射频链, 如果频带 1 已经用了一个射频链, 频带 2也用了 一个射频链, 那么射频链状态为非空闲状态, 定位服务器可以根据射频链非 空闲状态的信息, 来选择在频带 1和频带 2上的频点发送 PRS的基站作为目 标基站, 以使移动终端对各目标基站发送的 PRS进行测量。
优选地, 在本实施例中, 所述测量状态信息还可以包括: 移动性测量的 定时和 /或测量的无线接入技术 (Radio Access Technology, 简称 RAT) ; 所述移动性测量的定时用于优先选择与所述移动性测量的定时一致的基 站作为目标基站;
所述 RAT用于优先选择同样 RAT的基站作为目标基站。
定位服务器会优先选择与移动终端定时一致的上述目标基站中的基站, 定位服务器也会优先选择与移动终端所支持的 RAT —致的上述目标基站中 的基站。
本实施例中, 根据移动终端的射频能力信息和 /或当前射频链的空闲状态 和 /或移动性测量的定时和 /或测量的 RAT, 为移动终端选择多个发送定位参 考信号的更合适的目标基站, 避免了对射频链的多次调整, 实现了移动终端 当前使用的测量载波和 /或测量频点上面的业务持续进行, 从而提高了吞吐 图 3为本发明移动终端定位测量处理方法实施例三的流程图, 图 4为本 发明移动终端定位测量处理方法实施例三的信令流程图, 在图 2所示方法实 施例的基础上, 如图 3、 4所示, 本实施例的移动终端定位测量处理方法可以 包括:
步骤 301、 向移动终端的服务基站发送测量状态信息请求; 或
向移动终端发送测量状态信息请求。
例如, 定位服务器可以向移动终端的服务基站发送测量状态信息请求, 也可以直接向移动终端发送测量状态信息请求, 测量状态信息请求可以通过
LPPa或 LPP信令发送。
步骤 302、 接收来自于移动终端的服务基站发送的测量状态信息; 或 接收来自于移动终端直接发送的测量状态信息。
如果在步骤 301 中, 向移动终端的服务基站发送测量状态信息请求, 则 定位服务器可以接收移动终端的服务基站发送的测量状态信息, 如果在步骤 301 中, 向移动终端发送测量状态信息请求, 则定位服务器可以接收移动终 端直接发送给定位服务器的测量状态信息, 上述测量状态信息包括移动终端 当前使用的测量载波和 /或测量频点, 可以通过 LPPa或 LPP信令发送。
步骤 303、 根据测量状态信息为移动终端选择多个发送定位参考信号的 目标基站, 目标基站为应用移动终端当前使用的测量载波和 /或测量频点发送 定位参考信号的基站。
与图 2所示方法实施例的实现原理类似, 此处不再赘述。
