信息传输方法及装置
相关申请的交叉引用
本申请要求在2019年11月25日提交中国专利局、申请号为201911168857.3、申请名称为“信息传输方法及装置”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，尤其涉及信息传输方法及装置。
背景技术
图1和图2以下行(Down Link，DL)观察到达时差(Observed Time Difference Of Arrival，OTDOA)定位为例，示出了目前方案中的常见的流程示意图，包括下面11个步骤：
步骤1、在用户终端(User Equipment，UE)建立与基站的连接之后，UE处于无线资源控制连接(Radio Resource Control Connected，RRC_CONNECTED)状态。
步骤2、定位服务器(Location Management Function，LMF)向UE发送“请求定位能力”消息，请求UE通知LMF该UE所能支持的定位功能。
步骤3、UE发送“提供定位能力”消息来响应LMF，“提供定位能力”消息上报UE支持OTDOA的定位能力。
步骤4、当需要下行定位辅助数据时，UE向LMF发送“请求定位辅助数据”消息，该消息用于请求LMF提供OTDOA辅助数据。
步骤5、LMF向基站发送“OTDOA信息请求”消息，该消息用于请求基站提供下行定位辅助数据，例如下行链路(Down Link，DL)定位参考信号(Positioning Reference Signal，PRS)配置数据。
步骤6、基站向LMF发送“OTDOA信息响应”消息，向LMF提供所请求 的下行定位辅助数据，包括PRS配置数据。
步骤7、LMF在“提供定位辅助数据”消息中提供UE所请求的定位辅助数据，其中，携带DL PRS配置数据。
步骤8、基站向UE发送DL PRS信号。
步骤9、UE利用定位辅助数据(例如：PRS配置数据)来测量下行信号以获得定位测量值，例如：参考信号的到达时间差(Reference Signal Time Difference，RSTD)，参考信号的接收功率(Reference Signal Received Power，RSRP)。
步骤10、UE向LMF发送“提供定位信息”消息，其中包括测量DL PRS所获得的定位测量值，例如：RSTD、RSRP。
步骤11、LMF根据PRS配置信息、各基站的发送天线的位置，以及UE上报的定位测量值来确定UE的位置。
其中，目前第三代合作伙伴计划(Third Generation partnership project，3GPP)协议中，步骤5中LMF向基站发送的“OTDOA信息请求”消息中只是触发基站向定位服务器提供所请求的下行定位辅助数据，并没有包含建议的下行定位参考信号的配置信息。
综上所述，图2的步骤5中LMF向基站发送的请求消息中只是触发基站向LMF提供所请求的下行定位辅助数据。在基站收到LMF请求消息后，各基站自主确定DL PRS信号的配置。目前的方法存在如下问题：相邻基站可能在相同的时间和频率资源上发送DL PRS，造成相邻基站DL PRS信号相互干扰，导致下行定位测量值性能下降；各基站不能根据UE的定位性能需求来优化配置DL PRS信号。

所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
本申请实施例提供了一种计算设备，该计算设备具体可以为桌面计算机、便携式计算机、智能手机、平板电脑、个人数字助理(Personal Digital Assistant，PDA)等。该计算设备可以包括中央处理器(Center Processing Unit，CPU)、存储器、输入/输出设备等，输入设备可以包括键盘、鼠标、触摸屏等，输出设备可以包括显示设备，如液晶显示器(Liquid Crystal Display，LCD)、阴极射线管(Cathode Ray Tube，CRT)等。

处理器通过调用存储器存储的程序指令，处理器用于按照获得的程序指令执行本申请实施例提供的任一所述方法。
本申请实施例提供了一种计算机存储介质，用于储存为上述本申请实施例提供的装置所用的计算机程序指令，其包含用于执行上述本申请实施例提供的任一方法的程序。
所述计算机存储介质可以是计算机能够存取的任何可用介质或数据存储设备，包括但不限于磁性存储器(例如软盘、硬盘、磁带、磁光盘(Magneto-Optical，MO)等)、光学存储器(例如光盘(Compact Disk，CD)、数字通用光盘(Digital Versatile Disc，DVD)、蓝光光碟(Blu-ray Disc，BD)、高清通用光盘(High-Definition Versatile Disc，HVD)等)、以及半导体存储器(例如ROM、可擦除可编程只读存储(Erasable Programmable Read-Only Memory，EPROM)、带电可擦可编程只读存储器(Electrically Erasable Programmable read only memory，EEPROM)、非易失性存储器(NAND FLASH)、固态硬盘((Solid State Disk，简称SSD)SSD))等。

综上所述，本申请实施例提出了一种LMF协调的定位方案，解决了现有方案可能存在的如下问题：
第一，没有在各个基站之间进行协商DL PRS的配置信息。相邻基站可能在相同的时间和频率资源上的发送DL PRS，造成相邻基站DL PRS信号相互干扰，导致下行定位测量值性能下降；
第二，不能支持各基站根据UE的定位性能需求来优化配置DL PRS信号。例如，可能在有的时候基站配置的DL PRS时间和频率资源不足(如：DL PRS带宽过小、时频域资源密度过低等)，不能满足UE的定位性能需求；而有的时候基站配置的DL PRS时间和频率资源过于浪费，由于资源浪费而对无线系统通信造成不利影响。
本领域内的技术人员应明白，本申请的实施例可提供为方法、系统、或计算机程序产品。因此，本申请可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本申请可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器和光学存储器等)上实施的计算机程序产品的形式。
本申请是参照根据本申请实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的 装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
