具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开实施例范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的,本文在表征大小关系时,所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说,可以理解:术语“大于”也涵盖了“大于等于”的含义,“小于”也涵盖了“小于等于”的含义;术语“高于”涵盖了“高于等于”的含义,“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种位置相关信息上报方法的示意流程图。本实施例所示的位置相关信息上报方法可以由终端执行,所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与基站通信,所述基站包括但不限于4G、5G、6G等通信系统中的基站。
如图1所示,所述位置相关信息上报方法可以包括以下步骤:
在步骤S101中,降低所述终端的位置相关信息的精度;
在步骤S102中,将降低精度后的位置相关信息上报至基站。
在一个实施例中,终端和基站可以通过地面网络通信,也可以通过非地面网络(Non-Terrestrial Networks,NTN)通信。本公开的技术方案可以适用于终端与基站在地面网络通信的场景,也可以适用于终端与基站在非地面网络通信的场景。以下主要 针对终端与基站在非地面网络通信的场景下对本公开技术方案进行示例性说明。
在非地面网络中,终端可以通过卫星与基站通信,例如基站将信号传输至卫星,卫星将信号传输至终端,其中卫星的工作模式主要包括两种,一种是透传模式,另一种是再生模式。
由于卫星在高空运动,其覆盖范围较大,覆盖范围甚至可以跨越几个国家,而不同国家的核心网可以有所不同,例如核心网中的接入移动管理功能AMF(Access and Mobility Management Function)不同,那么针对卫星覆盖范围内的终端,就需要根据终端的位置为终端选择合适的核心网接入。针对这种情况,对于终端的位置要求精度一般不高,2千米的精度即可。
当然,除了这种情况,本公开对于其他要求位置的精度不高的情况也适用,甚至一些实施例可以不考虑网络侧对于位置的精度要求。
根据本公开的实施例,终端可以确定自身的位置相关信息,并降低位置相关信息的精度,进而将降低精度后的位置相关信息上报至基站,有利于避免基站等网络侧设备获取到精度过高的位置相关信息而导致终端使用者的隐私泄露。
在一个实施例中,所述位置相关信息包括以下至少之一:
位置坐标信息、定时提前量TA(Timing Advance)。
其中,所述TA可以是终端预补偿的上行TA。在非地面网络中,网络侧难以确定终端的上行TA,所以难以由网络补偿上行TA,可以由终端自身对于上行TA进行预补偿。
在一个实施例中,终端上报位置相关信息的触发事件包括以下至少之一:
定时提前量上报TA report、最小化路测MDT(Minimization of Drive-Test)、自组织网络SON(Self Organization Network,也可以称作自优化网络)、基站指示上报位置相关信息。
其中,终端在进行MDT的情况下,可以在连接态将位置相关信息携带在测量报告中发送至基站;终端在进行SON的情况下,可以在连接态将位置相关信息携带在测量报告中发送至基站;终端在预补偿TA的情况下,可以将位置相关信息发送至基站;终端在接收到基站指示,确定需要上报位置相关信息是,也可以将位置相关信息发送至基站。
针对触发事件为MDT或者SON这两种情况,基站可以在连接重配置消息中携带测量配置,在测量配置的上报配置信息元素IE中可以携带有事件触发配置和/或周期性报告配置,可以在事件触发配置或周期性报告配置中携带指示,以指示终端上报位置相关信息。终端则可以基于事件触发配置中配置的事件上报位置相关信息,或者基于周期性报告配置中配置的周期上报位置相关信息。
其中,触发配置和/或周期性报告配置中的指示例如可以携带在以下至少一个IE中:
include CommonLocationInfo-r16 IE;
include BT-Meas-r16 IE;
include WLAN-Meas-r16 IE;
include Sensor-Meas-r16 IE。
在一个实施例中,所述方法还包括:在根据所述基站的指示确定需要上报未降低精度的位置相关信息时,将未降低精度的位置相关信息上报至所述基站。
在一个实施例中,终端除了向基站上报降低精度后的位置相关信息,也可以将降低精度前的位置相关信息上报给基站,还可以即上报降低精度后的位置相关信,又上报降低精度前的位置相关信息,具体可以根据基站的指示确定,例如基站指示需要上报未降低精度的位置相关信息时,那么可以将未降低精度的位置相关信息上报至所述基站。其中,可以在事件触发配置或周期性报告配置中携带指示,指示需要上报未降低精度的位置相关信息。
也就是说,终端既可以向基站上报降低精度前的位置相关信息,也可以向基站上报降低精度后的位置相关信息,为了使基站确定接收到的位置相关信息是否被降低过精度,终端上报位置相关信息后,还可以指示上报的所述位置相关信息是否被降低过精度。
其中,基站也可以根据终端的签约信息,判断上报未降低精度的位置信息是否有终端同意user consent,若终端同意上报未降低精度的位置信息,基站才会根据需要指示终端上报未降低精度的位置相关信息,若终端不同意上报未降低精度的位置信息,基站不回指示终端上报未降低精度的位置相关信息。
关于如何降低位置相关的精度,以下通过几个实施例进行示例性说明。在一个 实施例中,降低所述终端的位置相关信息的精度的方式包括以下至少之一:
将所述位置相关信息中预设位的数值设置为指定值;
将所述位置相关信息中预设位的数值设置为随机值;
将所述位置相关信息中预设位的数值加上、或减去、或乘以、或除以随机值;
忽略所述位置相关信息中预设位的数值。
需要说明的是,预设位可以是位置相关信息中的一位或多位,可以是连续的多位或者不连续的多位,以下主要在预设位为位置相关信息最低的几位的情况下,对本公开进行示例性描述。例如预设位为位置相关信息最低的两位。
在一个实施例中,可以通过将位置相关信息中预设位的数值设置为指定值,例如置零,来实现降低精度。例如位置相关信息是位置坐标信息,通过经纬度表示,经度和维度精确到小数点后两位,那么可以将小数点后两位置零来降低位置相关信息的精度;例如位置相关信息是TA,通过毫秒级时间表示,时间精确到小数点后两位,那么可以将小数点后两位置零来降低位置相关信息的精度。
在一个实施例中,可以通过将位置相关信息中预设位的数值设置为随机值,来实现降低精度。例如位置相关信息是位置坐标信息,通过经纬度表示,经度和维度精确到小数点后两位,那么可以将小数点后两位设置为随机值来降低位置相关信息的精度;例如位置相关信息是TA,通过毫秒级时间表示,时间精确到小数点后两位,那么可以将小数点后两位设置为随机值来降低位置相关信息的精度。
在一个实施例中,可以通过将位置相关信息中预设位的数值加上、或减去、或乘以、或除以随机值,来实现降低精度。例如位置相关信息是位置坐标信息,通过经纬度表示,经度和维度精确到小数点后两位,那么可以将小数点后两位加上一个随机值来降低位置相关信息的精度;例如位置相关信息是TA,通过毫秒级时间表示,时间精确到小数点后两位,那么可以将小数点后两位减去一个随机值来降低位置相关信息的精度。
在一个实施例中,可以通过忽略位置相关信息中预设位的数值,来实现降低精度。例如位置相关信息是位置坐标信息,通过经纬度表示,经度和维度精确到小数点后两位,那么忽略后两位(也即仅保留整数值)降低位置相关信息的精度;例如位置相关信息是TA,通过毫秒级时间表示,时间精确到小数点后两位,那么忽略后两位(也即仅保留整数值)降低位置相关信息的精度
需要说明的是,在位置相关信息为TA的情况下,由于TA的数量级一般很小,例如在毫秒级,如果调整精度的幅度较大,可能会严重影响TA的准确度,所以对于TA而言,主要可以采用幅度较小的降低精度方式,例如将位置相关信息中预设位的数值加上、或减去随机值的方式。
在一个实施例中,所述位置相关信息为位置坐标信息时,所述降低精度后的位置相关信息携带在信息元素IE中发送至所述基站,所述信息元素包括以下至少之一:
位置坐标信息元素locationCoordinate IE;
蓝牙日志测量结果表格信息元素LogMeasResultListBT IE;
无线局域网日志测量结果表格信息元素LogMeasResultWLAN IE;
传感器位置信息信息元素Sensor-LocationInfo IE。
图2是根据本公开的实施例示出的另一种位置相关信息上报方法的示意流程图。如图2所示,所述信息元素为所述位置坐标信息元素时,所述降低所述终端的位置相关信息的精度的步骤包括:
在步骤S201中,通过调整所述位置坐标信息元素中的uncertainty字段降低所述位置相关信息的精度。
在locationCoordinate IE中,uncertainty字段可以表示一个椭圆形的范围,位置相关信息位于该范围内,但是并不是具体确定的,该范围越小,那么位置相关信息的精度越高,该范围越大,那么位置相关信息的精度越低。
因此,可以通过调整uncertainty字段来改变上述范围,进而实现对位置相关信息精度的调整。
其中,还可以将uncertainty字段设置为一个与基站约定的特殊值,从而上报locationCoordinate IE后,基站根据uncertainty字段为特殊值,即可确定位置相关信息的精度经过调整。
图3是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图3所示,所述信息元素包括蓝牙日志测量结果表格信息元素和/或无线局域网日志测量结果表格信息元素,所述降低所述终端的位置相关信息的精度的步骤包括:
在步骤S301中,通过调整所述蓝牙日志测量结果表格信息元素和/或无线局域网日志测量结果表格信息元素中的接收信号强度指示字段,降低所述位置相关信息的 精度。
在LogMeasResultListBT IE或者LogMeasResultWLAN IE中,位置相关信息可以根据接收信号强度指示RSSI(Received Signal Strength Indication)字段确定,因此,可以通过调整RSSI字段来降低所述位置相关信息的精度。
其中,RSSI字段的单位可以是dB,因此,对于RSSI字段的调整,除了可以采用将位置相关信息中预设位的数值加上、或减去随机值的方式,还可以采用将位置相关信息中预设位的数值乘以、或除以随机值的方式。
图4是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图4所示,所述信息元素为所述传感器位置信息信息元素时,所述降低所述终端的位置相关信息的精度的步骤包括:
在步骤S401中,通过调整所述传感器位置信息信息元素中的大气压字段降低所述位置相关信息的精度。
在Sensor-LocationInfo IE中,位置相关信息可以根据大气压字段确定,例如可以用于确定位置相关信息中垂直于水平面方向上的位置相关信息,因此,可以通过调整大气压字段来降低所述位置相关信息的精度。
图5是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图5所示,所述方法还包括:
在步骤S501中,指示上报位置相关信息的目的,其中,所述目的包括以下至少之一:定时提前量上报TA report、最小化路测MDT、自组织网络SON。
在一个实施例中,终端在上报降低精度后的位置相关信息后,还可以指示上报位置相关信息的目的,从而使得基站确定终端上报位置相关信息的目的,以便根据终端上报的精度后的位置相关信进行适当地操作。
图6是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图6所示,所述降低所述终端的位置相关信息的精度的步骤包括:
在步骤S601中,根据所述基站指示的精度降低要求,降低所述位置相关信息的精度。
在一个实施例中,基站可以向终端指示精度降低要求,指示需要将精度降低到何种程度,例如可以将精度降低到2千米,那么终端可以根据该精度降低要求来降低 位置相关信息的精度,确保上报的降低精度后的位置相关信息能够满足基站需要。
在一个实施例中,所述将降低精度后的位置相关信息上报至基站包括:
在满足触发条件的情况下,上报所述降低精度后的位置相关信息。
其中,触发条件可以是协议约定的,或者是基站与终端约定的,或者是基站配置给终端的,终端在上报位置相关信息时,可以先判断是否满足触发条件,在满足触发条件的情况下才上报位置相关信息。
例如在基站配置的情况下,基站可以在NR(New Radio,新空口)报告配置ReportConfigNR IE的触发事件配置EventTriggerConfig中携带触发条件。
在一个实施例中,所述位置相关信息为位置坐标信息时,所述触发条件包括位置偏移阈值;
其中,在当前位置坐标信息到前一次上报位置相关信息时的位置之间的距离大于所述位置偏移阈值offset时,确定满足所述触发条件。
终端在需要上报降低精度后的位置相关信息时,可以先确定前一次上报位置相关信息时终端的位置,例如称作P0,以及终端的当前位置,例如称作P1,进而计算P0和P1之间的距离P01,在P01大于offset的情况下,可以确定满足触发条件,进而上报降低精度后的位置相关信息。
需要说明的是,前一次上报位置相关信息,可以是指前一次上报未降低精度的位置相关信息。当然,也可以根据需要进行设置,例如设置为前一次上报降低精度的位置相关信息或者上报未降低精度的位置相关信息。
在一个实施例中,所述位置相关信息为位置坐标信息时,所述触发条件包括位置偏移阈值offset和迟滞门限Hysteresis;
其中,在当前位置到前一次上报位置相关信息时的位置之间的距离与所述迟滞门限的差值大于所述位置偏移阈值时,确定满足所述触发条件;在当前位置到前一次上报位置相关信息时的位置之间的距离与所述迟滞门限之和小于所述位置偏移阈值时,确定不满足所述触发条件;或者
在当前位置到前一次上报位置相关信息时的位置之间的距离与所述迟滞门限之和小于所述位置偏移阈值时,确定满足所述触发条件;在当前位置到前一次上报位置相关信息时的位置之间的距离与所述迟滞门限的差值大于所述位置偏移阈值时,确 定不满足所述触发条件。
终端在需要上报降低精度后的位置相关信息时,可以先确定前一次上报位置相关信息时终端的位置,例如称作P0,以及终端的当前位置,例如称作P1,进而计算P0和P1之间的距离P01,然后基于P01和Hysteresis与offset之间的关系,确定是否满足触发条件。
例如,可以设置P01-Hysteresis>offset的情况为满足触发条件;
以及设置P01+Hysteresis<offset的情况为不满足触发条件。
或者可以设置P01+Hysteresis<offset的情况为满足触发条件;
以及设置P01-Hysteresis>offset的情况为不满足触发条件。
那么终端在确定满足触发条件的情况下,可以触发上报降低精度后的位置相关信息;而在确定不满足触发条件的情况下,则不必上报降低精度后的位置相关信息,如果当前正在上报(例如周期性上报)降低精度后的位置相关信息,可以停止上报降低精度后的位置相关信息。
在一个实施例中,针对所述触发条件,还可以设置生效时间,那么当终端确定满足触发条件,且当前处于生效时间内时,才触发上报降低精度后的位置相关信息,而若当前不处于生效时间内,则不必触发上报降低精度后的位置相关信息。
在一个实施例中,在位置相关信息为TA的情况下,终端上报TA的方式主要包括以下两种,一种是TA上报(TA report)的方式(上报内容可以是TA或者位置坐标信息),这种方式通过介质方为控制层控制元素(MAC CE)携带TA进行上报;另一种是上报用户设备位置(UE location)的方式(上报内容可以是TA或者位置坐标信息),这种方式通过无线资源控制(RRC)信令携带TA进行上报。以下主要针对这两种情况进行示例性说明。
图7是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图7所示,所述位置相关信息为定时提前量TA时,所述方法还包括:
在步骤S701中,在根据所述基站的指示确定通过定时提前量上报的方式上报定时提前量时,根据当前定时提前量和最近一次位置相关信息上报时的定时提前量之间的变化量,确定是否满足所述触发条件。
在一个实施例中,基站可以指示终端上报TA的方式,例如上报方式为TA上 报,终端可以确定最近一次位置相关信息上报时的定时提前量,例如称作TA0,以及当前定时提前量,例如称作TA1,进而计算TA0和TA1之间的变化量TA01,并根据TA01确定是否确定满足触发条件。
例如TA01大于TA阈值,则确定满足触发条件,才触发上报降低精度后的位置相关信息;例如TA01小于TA阈值,则确定不满足触发条件,那么不触发上报降低精度后的位置相关信息。
其中,最近一次位置相关信息上报,上报的可以是TA,也可以是位置坐标信息。
在一个实施例中,所述根据当前定时提前量TA和最近一次位置相关信息上报时的定时提前量TA之间的变化量,确定是否满足所述触发条件包括:
根据当前定时提前量和最近一次位置相关信息上报且上报内容为定时提前量时的定时提前量之间的变化量,确定是否满足所述触发条件。
也即可以设置终端确定最近一次位置相关信息上报时的定时提前量,具体可以是最近一次位置相关信息上报时,且上报的内容为TA时的TA。
图8是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图8所示,所述上报所述降低精度后的位置相关信息包括:
在步骤S801中,在根据所述基站的指示确定通过其他方式上报位置相关信息的情况下,在已触发通过TA上报的方式上报TA时,取消通过TA上报的方式上报TA。
在一个实施例中,基站在指示终端通过TA上报的方式上报TA的情况下,还可能也指示了终端通过其他方式上报位置相关信息,例如上报位置相关信息的目的为MDT或者SON,那么其他方式是指MDT或者SON过程中上报位置相关信息的方式上报位置相关信息。
在这种情况下,终端既需按照TA上报的方式上报TA,又需要按照其他方式上报位置相关信息,但是TA和位置相关信息对于网络侧的作用一般是相近的,所以一般情况下无需既按照TA上报的方式上报TA又按照其他方式上报位置相关信息。
因此,在本实施例中,在已触发通过TA上报的方式上报TA时,可以取消通过TA上报的方式上报TA,例如在携带TA的MAC CE尚未递交该下层时,或者尚未 放入MAC PDU(协议数据单元)时,可以执行取消动作。据此,可以避免重复上传作用相近的信息,有利于节约通信资源。
图9是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图9所示,所述位置相关信息为定时提前量TA时,所述方法还包括:
在步骤S901中,在根据所述基站的指示确定通过上报用户设备位置的方式上报定时提前量时,根据当前位置和最近一次上报位置相关信息时所述终端的位置之间的变化量,确定是否满足所述触发条件。
在一个实施例中,基站可以指示终端上报TA的方式,例如上报方式为TA上报,终端可以确定最近一次位置相关信息上报时终端的位置,例如L0,以及当前定位置,例如称作L1,进而计算L0和L1之间的变化量L01,并根据L01确定是否确定满足触发条件。
例如L01大于TA阈值,则确定满足触发条件,才触发上报降低精度后的位置相关信息;例如L01小于TA阈值,则确定不满足触发条件,那么不触发上报降低精度后的位置相关信息。
其中,最近一次位置相关信息上报,上报的可以是TA,也可以是位置坐标信息。
在一个实施例中,所述根据当前位置和最近一次上报位置相关信息时所述终端的位置之间的变化量,确定是否满足所述触发条件包括:
根据当前位置和最近一次位置相关信息上报且上报内容为位置坐标信息时所述终端的位置之间的变化量,确定是否满足所述触发条件。
也即可以设置终端确定最近一次位置相关信息上报时终端的位置,具体可以是最近一次位置相关信息上报时,且上报的内容为位置坐标时终端的位置。
图10是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图10所示,所述上报所述降低精度后的位置相关信息包括:
在步骤S1001中,在根据所述基站的指示通过其他方式上报位置相关信息的情况下,在已触发通过上报用户设备位置的方式上报TA的情况下,取消通过上报用户设备位置的方式上报TA,或者通过上报用户设备位置的方式上报TA且通过其他方式上报位置相关信息。
一个实施例中,基站在指示终端通过UE location上报的方式上报TA的情况下,还可能也指示了终端通过其他方式上报位置相关信息,例如上报位置相关信息的目的为MDT或者SON,那么其他方式是指MDT或者SON过程中上报位置相关信息的方式上报位置相关信息。
在这种情况下,终端既需要通过UE location上报的方式上报TA,又需要通过其他方式上报位置相关信息,但是TA和位置相关信息对于网络侧的作用一般是相近的,所以一般情况下无需既通过UE location上报的方式上报TA又通过其他方式上报位置相关信息。
因此,在本实施例中,在已触发通过其他方式上报位置相关信息,又触发通过UE location上报的方式上报TA时,可以尝试取消通过UE location上报的方式上报TA,据此,可以避免重复上传作用相近的信息,有利于节约通信资源。
但是由于通过UE location上报的方式上报TA,是将TA携带在RRC信令中上报,取消动作可能失败,所以也可以既通过其他方式上报位置相关信息,又通过UE location上报的方式上报TA。
在终端既通过其他方式上报位置相关信息,又通过UE location上报的方式上报TA的情况下,通过其他方式上报的位置相关信息可能也是TA,这可能会导致基站接收到两个TA,而导致难以区分两个TA的作用。因此,在这种情况下,终端可以指示通过UE location上报的方式上报TA的目的,和通过其他方式上报的位置相关信息的目的,例如TA report、UE location、MDT、SON等,以便基站可以针对接收到的两个信息进行适当的处理。另外还可以指示上报的哪个信息被降低了精度,哪个信息没有被降低精度。
图11是根据本公开的实施例示出的又一种位置相关信息上报方法的示意流程图。如图11所示,所述方法还包括:
在步骤S1101中,在需要切换到目标基站时,向所述目标基站发送所述位置相关信息。
在一个实施例中,在终端确定需要切换基站时,可以确定需要切换到的目标基站,进而将位置相关信息上报给目标基站,以便目标基站及时确定终端的位置相关信息。
在一个实施例中,向所述目标基站发送所述位置相关信息包括:在切换到所述 目标基站过程中向所述目标基站发送所述位置相关信息。
终端可以在切换到目标基站的过程中将位置相关信息发送至目标基站,例如通过连接重配置完成消息携带位置相关信息发送至目标基站,以便目标基站能够尽早确定终端的位置相关信息。
在一个实施例中,所述向所述目标基站发送所述位置相关信息包括:在根据所述目标基站发送的重配置消息确定需要上报位置相关信息的情况下,在切换到所述目标基站过程中和/或切换到所述目标基站之后,向所述目标基站发送所述位置相关信息。
终端可以先根据目标基站发送的重配置消息确定是否需要上报位置相关信息,在确定需要上报位置相关信息的情况下,可以在切换到目标基站的过程中将位置相关信息发送至目标基站,例如通过连接重配置完成消息携带位置相关信息发送至目标基站,也可以在切换到目标基站后将位置相关信息发送至目标基站,例如通过触发测量上报,在将位置相关信息携带在测量报告中发送至目标基站。
而在确定不需要上报位置相关信息的情况下,可以不必将位置相关信息发送至目标基站。据此,可以避免不必要的位置相关信息上报,有利于避免通信资源浪费。
需要说明的是,上报给目标基站的位置相关信息,可以是降低精度后的位置相关信息,也可以是未降低精度的位置相关信息,具体可以根据需要进行设置。
在一个实施例中,基于以下至少一项确定是否在未存储可用available位置相关信息的情况下,获取位置相关信息降低精度后进行上报:
所述基站的指示;
上报所述位置相关信息的触发事件;
上报所述位置相关信息的目的;
所述终端所处状态;
所述位置相关信息需要降低到的精度。
在一个实施例中,终端在需要上报降低精度的位置相关信息时,首先需要存储有可用位置相关信息,也即available位置相关信息,例如终端中存储有位置相关信息,且位置相关信息并未失效,例如所存储的位置相关信息的获取时刻与当前时刻的时间差小于预设时长,那么可以确定终端存储有available位置相关信息。
但是,在某些情况下,终端中并未存储有available位置相关信息,在这种情况下,终端可以选择不上报降低精度后的位置相关信息,也可以选择获取位置相关信息,然后将获取到的位置相关信息降低精度后上报,而具体执行这两种操作中的哪种操作,可以根据所述基站的指示,也可以根据上报所述位置相关信息的触发事件确定,也可以根据上报所述位置相关信息的目的确定,也可以根据所述终端所处状态确定,也可以根据所述位置相关信息的精度确定。
例如根据基站的指示确定:
基站在指示终端上报位置相关信息时,如果明确指示终端上报available位置相关信息,那么终端在触发位置相关信息上报时,如果未存储available位置相关信息,可以不必获取位置相关信息,如果存储了available位置相关信息,则上报available位置相关信息;
如果仅指示终端上报位置相关信息,那么终端在触发位置相关信息上报时,如果未存储available位置相关信息,可以获取位置相关信息,然后将获取到的位置相关信息降低精度后上报,如果存储了available位置相关信息,则将存储的available位置相关信息降低精度后上报。
另外,如果基站并没有指示上报available位置相关信息,也没有指示上报位置相关信息,那么终端在触发位置相关信息上报时,如果未存储available位置相关信息,可以不必获取位置相关信息,如果存储了available位置相关信息,则上报available位置相关信息。
例如根据上报所述位置相关信息的触发事件确定:
基站可以为终端配置上报位置相关信息的触发事件,终端在触发位置相关信息上报时,可以先确定是否满足触发事件,满足触发事件才上报,不满足触发事件则不上报。
而在确定满足触发事件的情况下,如果终端并未存储available位置相关信息,那么可以根据触发事件确定是否获取位置相关信息。例如基站配置触发事件A需要终端上报available位置相关信息,触发事件B需要终端上报位置相关信息,那么当满足触发事件A时,终端如果未存储available位置相关信息,可以不必获取位置相关信息,如果存储了available位置相关信息,则上报available位置相关信息;当满足触发事件B时,如果未存储available位置相关信息,可以获取位置相关信息,然后将获取到的 位置相关信息降低精度后上报,如果存储了available位置相关信息,则将存储的available位置相关信息降低精度后上报。
例如根据上报所述位置相关信息的目的确定:
基站可以为终端配置上报位置相关信息的目的,例如TA report、SON、MDT、LCS(定位服务)等,终端在触发位置相关信息上报时,如果终端并未存储available位置相关信息,那么可以根据所述目的确定是否获取位置相关信息。
例如基站目的TA report需要终端上报available位置相关信息,目的MDT需要终端上报位置相关信息,那么当终端确定目的为TA report时,终端如果未存储available位置相关信息,可以不必获取位置相关信息,如果存储了available位置相关信息,则上报available位置相关信息;当终端确定目的为MDT时,如果未存储available位置相关信息,可以获取位置相关信息,然后将获取到的位置相关信息降低精度后上报,如果存储了available位置相关信息,则将存储的available位置相关信息降低精度后上报。
例如根据所述终端所处状态确定:
终端触发位置相关信息上报时,如果终端并未存储available位置相关信息,可以根据自身状态确定是否获取位置相关信息。
例如终端在处于初始随机接入状态、或者切换基站状态时,终端如果未存储available位置相关信息,可以获取位置相关信息,然后将获取到的位置相关信息降低精度后上报,如果存储了available位置相关信息,则将存储的available位置相关信息降低精度后上报。
另外,终端在处于连接态时,如果触发上报位置相关信息的触发事件为当前的位置相关信息与最近一次上报的位置相关信息之间的差异较大,例如大于预设值,终端如果未存储available位置相关信息,可以获取位置相关信息,然后将获取到的位置相关信息降低精度后上报,如果存储了available位置相关信息,则将存储的available位置相关信息降低精度后上报。
而终端在处于其他状态时,终端如果未存储available位置相关信息,可以不必获取位置相关信息,如果存储了available位置相关信息,则上报available位置相关信息。
例如根据所述位置相关信息的精度确定:
基站可以指示终端对于位置相关信息所需降低到的精度,终端也可以自主确定对于位置相关信息所需降低到的精度。终端触发位置相关信息上报时,如果终端并未存储available位置相关信息,可以根据对于位置相关信息所需降低到的精确定是否获取位置相关信息。对于这种情况,基站可以不必再指示终端是否上报available位置相关信息。
例如终端确定需要上报粗精度(例如精度低于预设精度)的情况下,终端如果未存储available位置相关信息,可以获取位置相关信息,然后将获取到的位置相关信息降低精度后上报,如果存储了available位置相关信息,则将存储的available位置相关信息降低精度后上报;例如终端确定需要上报高精度(例如精度高于预设精度)的情况下,终端如果未存储available位置相关信息,可以不必获取位置相关信息,如果存储了available位置相关信息,则上报available位置相关信息。
图12是根据本公开的实施例示出的一种位置相关信息接收方法的示意流程图。本实施例所示的位置相关信息接收方法可以由基站执行,所述基站可以与终端通信,所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置,所述基站包括但不限于4G、5G、6G等通信系统中的基站。
如图12所示,所述位置相关信息接收方法可以包括以下步骤:
在步骤S1201中,接收终端发送的降低精度后的位置相关信息。
在一个实施例中,终端和基站可以通过地面网络通信,也可以通过非地面网络通信。本公开的技术方案可以适用于终端与基站在地面网络通信的场景,也可以适用于终端与基站在非地面网络通信的场景。以下主要针对终端与基站在非地面网络通信的场景下对本公开技术方案进行示例性说明。
在非地面网络中,终端可以通过卫星与基站通信,例如基站将信号传输至卫星,卫星将信号传输至终端,其中卫星的工作模式主要包括两种,一种是透传模式,另一种是再生模式。
由于卫星在高空运动,其覆盖范围较大,覆盖范围甚至可以跨越几个国家,而不同国家的核心网可以有所不同,例如核心网中的接入移动管理功能AMF不同,那么针对卫星覆盖范围内的终端,就需要根据终端的位置为终端选择合适的核心网接入。针对这种情况,对于终端的位置要求精度一般不高,2千米的精度即可。
当然,除了这种情况,本公开对于其他要求位置的精度不高的情况也适用,甚 至一些实施例可以不考虑网络侧对于位置的精度要求。
根据本公开的实施例,终端可以确定自身的位置相关信息,并降低位置相关信息的精度,进而将降低精度后的位置相关信息上报至基站,有利于避免基站等网络侧设备获取到精度过高的位置相关信息而导致终端使用者的隐私泄露。
在一个实施例中,所述位置相关信息包括以下至少之一:
位置坐标信息、定时提前量TA(Timing Advance)。
其中,所述TA可以是终端预补偿的上行TA。在非地面网络中,网络侧难以确定终端的上行TA,所以难以由网络补偿上行TA,可以由终端自身对于上行TA进行预补偿。
在一个实施例中,所述位置相关信息为位置坐标信息时,在信息元素IE中获取所述降低精度后的位置相关信息,所述信息元素包括以下至少之一:
位置坐标信息元素locationCoordinate IE;
蓝牙日志测量结果表格信息元素LogMeasResultListBT IE;
无线局域网日志测量结果表格信息元素LogMeasResultWLAN IE;
传感器位置信息信息元素Sensor-LocationInfo IE。
图13是根据本公开的实施例示出的另一种位置相关信息接收方法的示意流程图。如图13所示,所述方法还包括:
在步骤S1301中,根据所述终端的指示确定所述终端上报位置相关信息的目的,其中,所述目的包括以下至少之一:定时提前量上报TA report、最小化路测MDT、自组织网络SON。
在一个实施例中,终端在上报降低精度后的位置相关信息后,还可以指示上报位置相关信息的目的,从而使得基站确定终端上报位置相关信息的目的,以便根据终端上报的精度后的位置相关信进行适当地操作。
图14是根据本公开的实施例示出的又一种位置相关信息接收方法的示意流程图。如图14所示,所述方法还包括:
在步骤S1401中,向所述终端发送精度降低要求。
在一个实施例中,基站可以向终端指示精度降低要求,指示需要将精度降低到 何种程度,例如可以将精度降低到2千米,那么终端可以根据该精度降低要求来降低位置相关信息的精度,确保上报的降低精度后的位置相关信息能够满足基站需要。
图15是根据本公开的实施例示出的又一种位置相关信息接收方法的示意流程图。如图15所示,所述方法还包括:
在步骤S1501中,接收所述终端发送的未降低精度的位置相关信息。
在一个实施例中,终端除了向基站上报降低精度后的位置相关信息,也可以将降低精度前的位置相关信息上报给基站,还可以即上报降低精度后的位置相关信,又上报降低精度前的位置相关信息,具体可以根据基站的指示确定,例如基站指示需要上报未降低精度的位置相关信息时,那么可以将未降低精度的位置相关信息上报至所述基站。其中,可以在事件触发配置或周期性报告配置中携带指示,指示需要上报未降低精度的位置相关信息。
也就是说,终端既可以向基站上报降低精度前的位置相关信息,也可以向基站上报降低精度后的位置相关信息,因此,终端上报位置相关信息后,还可以指示上报的位置相关信息是否被降低过精度,以便基站确定接收到的位置相关信息是否被降低过精度。
其中,基站也可以根据终端的签约信息,判断上报未降低精度的位置信息是否有终端同意user consent,若终端同意上报未降低精度的位置信息,基站才会根据需要指示终端上报未降低精度的位置相关信息,若终端不同意上报未降低精度的位置信息,基站不回指示终端上报未降低精度的位置相关信息。
图16是根据本公开的实施例示出的又一种位置相关信息接收方法的示意流程图。如图16所示,所述方法还包括:
在步骤S1601中,在所述终端需要切换到目标基站时,向所述目标基站发送所述位置相关信息。
在一个实施例中,在终端确定需要切换基站时,可以确定需要切换到的目标基站,进而将位置相关信息发送给目标基站,例如通过基站间接口发送,或者通过核心网发送,以便目标基站及时确定终端的位置相关信息。另外,还可以指示发送给目标基站的位置相关信息是降低过精度的,还是未降低过精度的。
