Description

一种解决测量冲突的方法及装置 本申请要求于 2012 年 6 月 1 日提交中国专利局、 申请号为 201210179116.7 , 发明名称为 "一种解决测量冲突的方法及装置" 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
本发明涉及通信技术领域, 尤其涉及一种解决测量冲突的方法及装 置。
背景技术
在 LTE R9 ( Long Term Evolution Release 9th, 长期演进第 9版) 中, UE( User Equipment,用户设备)从网络侧下发的 0TD0A( Observation Time Difference of Arrival, 参考信号时间差) 辅助数据消息所携带的 信息中获取釆集含有多个小区 PRS ( Position Reference Signal, 定位 参考信号)的接收信号的起始时刻和长度, 其中, 该接收信号的起始时刻 和长度构成 RSTD ( Reference Signal Time Difference, 参考信号时间 差 )同频测量观察窗。 若该 RSTD同频测量观察窗只包含与该 UE的服务小 区处于同一频率层的小区的 PRS信号, 则可称为 RSTD同频测量观察窗。 该 UE在 RSTD同频测量观察窗内测量与该 UE的服务小区处于同一频率层 的各个小区的 PRS对应的 RSTD, 并将测量结果上报到网络侧, 网络侧根 据该测量结果进行定位计算, 来估计该 UE 当前所在位置。 这种定位方法 称为 RSTD同频测量。
同时, 网络侧为了对 UE进行移动性管理, UE通常还需要进行异频测 量,包括对和服务小区处于不同频率层的邻居小区参考信号接收功率进行 测量以及对与该 UE所在小区处于不同频层的各个小区的 PRS对应的 RSTD 进行测量等。 此时, 网络侧会通过调度周期性测量间隙 GAP来满足 UE进 行异频测量的需求。 GAP结构与 RSTD 同频测量观察窗类似, 也具有起始 时刻和长度, 从而形成异频测量观察窗。 此时, 就会有在进行 RSTD同频测量的同时, UE还要进行异频测量这 样的情况出现。 当 RSTD同频测量观察窗与异频测量观察窗在时间上发生 重叠时,由于 UE射频不能在重叠区域不能同时工作在两个频点接收信号, 就会造成测量冲突, 导致 RSTD同频测量和异频测量中存在一种测量不能 正常进行。

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,所描述的实施例仅仅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。
实施例 1
本发明实施例提供了一种解决测量冲突的方法,该方法由用户设备实 现, 该用户设备可以是服务器、 计算机、 手机、 笔记本或掌上电脑等。 如 图 1所示, 该方法包括: 101、 获取当前 RSTD ( Reference Signal Time Difference, 参考信 号时间差 ) 同频测量观察窗以及当前异频测量间隙 GAP。
其中, 所述获取当前参考信号时间差 RSTD同频测量观察窗可以通过 方法 A来实现, 方法 A具体包括:
根据下发的 otdoa辅助数据消息中 prs_conf igurationlndex字段和 服务小区当前系统帧号 SFN ( Symtem Frame Number ), 获得服务小区 PRS 子帧起始位置 PRS_subframe_start。
根据该 otdoa辅助数据消息中 numDL-Frames字段, 计算出本频率层 上各小区的最大子帧数。然后根据 otdoa辅助数据消息中的 expectedRSTD 字段和 expectedRSTD-Uncertainty字段计算出本频率层中数据开窗大小 max ( ( expectedRSTD-8192 ) *3+ ( expectedRSTD-Uncertainty ) *3)。
基于上述计算结果, 可以确定该 RSTD同频测量观察窗的起始位置、 终止位置和观察窗长度, 单位为 Ts = l/30.72M。
该 RSTD同频测量观察窗的起始位置为:
Otdoa.s tart = PRS.sub frame .start - max ( ( expectedRSTD-8192 ) * 3 + ( expectedRSTD-Uncertainty ) *3)。
该 RSTD同频测量观察窗的终止位置为:
0tdoa_end = PRS_subframe .start + max (numDL-Frames) * 30720 + max ( ( expectedRSTD-8192 ) *3 + ( expectedRSTD-Uncertainty ) *3)。
该 RSTD同频测量观察窗的程度为:
0 tdoa -Leng th=max (numDL-Frames) *30720+2*max
( ( expectedRSTD-8192 ) *3 + ( expectedRSTD-Uncertainty ) *3)。
其中 , 需要说明的是, 所述 prs-conf igurat ion Index 字段、 numDL-Frames字段、 expectedRSTD字段以及 expec tedRSTD-Uncer t a inty 字段均为 otdoa辅助数据消息中已有的字段,是现有技术中已定义好的字 段, 本实施例中在执行方法 A时直接使用这些字段。
当然, 获取当前 RSTD同频测量观察窗的实现方法并不局限于方法 A, 本发明实施例对此不进行限制。
其中,所述获取当前 GAP可以通过方法 B来实现,该方法 B具体包括: 通过异频测量消息中 Mea s GapConf i g 字段确定当前 GAP模式, 并通 过当前 GAP模式确定当前 GAP周期和子帧偏移。 其中, GAP有两种模式 0 模式和 1模式, 0模式是 40ms的周期, 子帧偏移可以配置 ( 0- 39 ), 1模 式是 80ms的周期, 子帧偏移可以配置 ( 0-79 )。
根据确定好的当前 GAP周期和子帧偏移,来确定当前 GAP的起始位置。 其中,每个 GAP的子帧编号从 0开始,子帧偏移表示与 0号子帧的偏移量。
并且, 由于 GAP长度为固定的 6ms , 所以当前 GAP可以根据确定好的 当前 GAP的起始位置和固定长度进行计算得到。
1 02、判断所述当前 RSTD同频测量观察窗与所述当前 GAP是否存在重 叠时间。
其中, 所述当前 RSTD同频测量观察窗与所述当前 GAP存在重叠时间 可以包括以下几种情况:
情况一: 当前 RSTD同频测量观察窗的起始位置落在当前 GAP中。 情况二: 当前 RSTD同频测量观察窗的终止位置落在当前 GAP中。 情况三: 当前 RSTD同频测量观察窗的起始位置和终止位置都落在当 前 GAP中
情况四: 当前 GAP的起始位置和终止位置都落在当前 RSTD同频测量 观察窗中。
1 03、若确定所述当前 RSTD同频测量观察窗与所述当前 GAP存在重叠 时间, 则按照配置策略进行 RSTD同频测量和 GAP异频测量。
其中, 所述按照配置策略进行 RSTD同频测量和 GAP异频测量具体可 以通过方法 1、 方法 2和方法 3中的任意一种方法实现, 具体为:
如图 2所示, 方法 1 包括:
A103 通过设置标志位禁止根据所述当前 GAP进行的异频测量。 其中, 标志位可以为一个硬件引脚, 设定为高电位表示禁止任何异频 测量, 低电位表示允许异频测量。 该标志位也可以为一个软件参数, 设定 为 1表示禁止任何异频测量, 0表示允许异频测量。 当然, 此处描述的标 志位设定方法只是一种举例, 本发明实施例对此不进行限制。
A1032 , 根据所述当前 RSTD同频测量观察窗进行同频测量。
其中, 所述根据所述当前 RSTD同频测量观察窗进行同频测量可以通 过现有技术实现, 本发明实施例在此不进行详细描述。
A1033、 在所述同频测量结束之后, 重设所述标志位, 以使得用户设 备能够进行在时间上处于所述当前 RSTD 同频测量观察窗之后的异频测 量。
其中,所述重设所述标志位这一动作与步骤 A1 031 中的设置标志位这 一动作为互为逆向操作, 举例来说, 若设置标志位的动作为将硬件引脚的 电平设置为高电位,则重设该标志位的动作为将硬件引脚的电平设置为低 电位。
在方法 1 中, 通过优先执行 RSTD同频测量, 放弃当前异频测量来保 证 RSTD同频测量的成功, 从而保证了对用户设备的成功定位。
如图 3所示, 方法 2包括:
B103 暂停根据当前 RSTD同频测量观察窗进行 RSTD同频测量。
B1032、根据所述当前 RSTD同频测量观察窗以及所述当前 GAP进行计 算, 生成第一同频测量状态指示信令, 并将所述第一同频测量状态指示信 令发送给基站,以使得所述基站在接收到所述第一同频测量状态指示信令 之后, 根据接收到的所述第一同频测量状态指示信令重新配置新的 GAP。 在未接收到所述基站发送的新的 GAP时, 执行步骤 B1 033 ; 在接收到所述 基站发送的新的 GAP时, 执行步骤 B 1 034。
其中,所述第一同频测量状态指示信令用于告知基站用户设备当前暂 停根据当前 RSTD同频测量观察窗进行 RSTD同频测量。
其中,所述第一同频测量状态指示信令用于告知基站用户设备当前暂 停根据当前 RSTD同频测量观察窗进行 RSTD同频测量,所述第一同频测量 状 态 指 示 信 令 可 以 通 过 重 用 现 有 技 术 中 提 供 的
InterFreqRSTDMea surement Ind ica t ion字段来实现。
具体方法为将 InterFreqRSTDMea surement Indication字段的名称重 新命名为 RSTDMeasurementlndication , 并将其中 包含的载频字段 carrierFreq字段、 GAP子帧偏移 measPRS_Of f set字段和 RSTD同频测量 状 态 指 示 字 段 rstdlndication 字 段 分 别 重 新 定 义 。 RSTDMeasurementlndication字段的具体定义内容如下表 1所示。
.1 RSTDMeasurementlndication 段描述

\ carrierFreq
\ The EARFCN value of the carrier received from upper layers for which the UE needs to \ perform the RSTD measurements.

\ received from upper layers. The value of measPRS-Offset is obtained by mapping the
\ starting subframe of the PRS positioning occasion in the measured cell to the
\ corresponding subframe in the serving cell and is calculated as the serving cell's

值得说明的是,所述第一同频测量状态指示信令可以通过重新定义一 个 新 的 字 段 来 实 现 。 该 字 段 命 名 为
IntraFreqRSTDMea surement Indication, 其包含 GAP 子帧第一偏移字段 measPRS- Offsetl、 GAP子帧第二偏移字段 measPRS-Of f set2以及 RSTD同 频 测 量 ^ 态 指 示 字 段 rstd-IntraFreqlndication 。 IntraFreqRSTDMeasurement Indicat ion字段的具体定义内容如下表 3 所 示。
表 3 Int raFreqRSTDMea surement Ind i ca t ion字段描述

\ Indicates the smallest offset of the GAP in the serving cell frequency-for which the UE \ needs to perform the intra-frequency RSTD measurements. The PRS positioning
\ occasion information is received from upper layers. The value of measPRS-Offsetl is \ obtained by mapping the smallest subframe to avoiding the observation interval of the ί PRS positioning occasion in the measured cell to the corresponding subframe in the ί serving cell and is calculated as the serving cell's subframe number mod current GAP ί period ms.

表 3内容的中文译文为如表 4所示。
Figure imgf000010_0001
进一步, 值得说明的是, 在 RSTDMea surement Indicat ion 字段中的 measPRS-Of f set或者是 IntraFreqRSTDMeasurement Indicat ion字段中的 measPRS- Off sel和 measPRS- Of fset2 , 都是需要才艮据当前 RSTD同频测量 观察窗与所述当前 GAP进行计算得到的,具体的计算方法如下,具体包括: 当 mod (otdoa— end, Gap— Per iod)大于 mod (otdoa.start, Gap-Period) 时 , GAP 起 始 位 置 的 子 帧 偏 移 ValidOff set 可 以 在 [mod (otdoa.s tart, Gap-Period), mod (otdoa_end, Gap-Period) -GAP- len 表示范围内取值。
当 mod (otdoa- start, Gap-Period) - GAP.len 小于或等于 0 时, GAP 起 始 位 置 的 子 帧 偏 移 ValidOff set 可 以 在 [mod (otdoa -end, Gap-Per iod) -GAP- len, Gap-Per iod- mod (otdoa.start, Gap-Period) ] 表示范围内取值。
当不属于上述两种情况时, GAP起始位置的子帧偏移 ValidOff set可 以 在 [mod (otdoa -end, Gap-Per iod) -GAP- len, Gap-Period] &&[0, mod (otdoa— st art, Gap-Period) - GAP— len]表示范围内取值。
这些 ValidOff set的取值范围表示不会与当前 RSTD同频测量观察窗 存在重叠时间的 GAP的范围。
基于上述 ValidOff set的取值范围, RSTDMea surement Ind i cat ion字 段中的 measPRS- Offset可以设置为 ValidOff set的取值范围中的任意一 个 值 , 而 Int raFreqRSTDMea surement Ind ica t ion 字 段 中 的 measPRS-Offsel和 measPRS-Of f set2用于表示 ValidOffset 的取值范围 中的任意一个封闭的子区间的下限和上限。
进 一 步 值 得 说 明 的 是 , 用 户 设 备 可 以 将 所 述 RSTDMea surementlndi cat ion 字 段 和
Int raFreqRSTDMea surement Ind ica t ion字段承载在 RRC ( Radio Resource Control, 无线资源控制协议) 信令发送给基站。
B1033、 保持所述当前 GAP配置不变, 并根据所述当前 GAP进行异频 测量。
需要说明的是,上述步骤 B1033只能够在用户设备为接收到基站发送 的新的 GAP 时执行, 当接收到新的 GAP 时, 则需要停止执行上述步骤 B1033, 并开始执行上述步骤 B1034。
B1034、 获取后继 RSTD同频测量观察窗。 其中,所述后继 RSTD同频测量观察窗为与当前 RSTD同频测量周期相 邻的下一个 RSTD同频测量周期内的 RSTD同频测量观察窗。
需要说明的是, 所述获取后继 RSTD同频测量观察窗的方法与所述步 骤 1 01 中获取当前 RSTD同频测量观察窗的方法类似, 本发明实施例对此 不再详细描述。
B1035、判断所述新的 GAP与所述后继 RSTD同频测量观察窗是否存在 重叠时间。 若确定所述新的 GAP与所述后继 RSTD同频测量观察窗不存在 重叠时间, 则执行步骤 B1 036 ; 否则执行步骤 B1 031。
B1036、 将所述当前 GAP的配置替换为所述新的 GAP的配置。
B1037、 根据所述后继 RSTD同频测量观察窗进行 RSTD同频测量, 将 所述第一同频测量状态指示信令修改为第二同频测量状态指示信令,并将 所述第二同频测量状态指示信令发送给基站, 其中, 所述第二同频测量状 态指示信令用于告知基站用户设备允许 RSTD同频测量。
其中,所述第二同频测量状态指示信令的结构与所述第一同频测量状 态指示信令的结构相同。
其中,所述将所述第一同频测量状态指示信令修改为第二同频测量状 态指示信令可以通过将第一同频测量状态指示信令中的 RSTD同频测量状 态指示字段内容进行修改, 也就是说, 若预先定义 RSTD同频测量状态指 示字段内容为 1表示用户设备禁止 RSTD同频测量, RSTD同频测量状态指 示字段内容为 0表示用户设备允许 RSTD同频测量, 则可以将第一同频测 量状态指示信令中的 RSTD 同频测量状态指示字段内容从 1修改为 0。 当 然, RSTD 同频测量状态指示字段的定义不同, 设置方法也不同, 本发明 实施例对此不进行限制。 而其他字段则可以保持不变。
B1038 , 才艮据新的 GAP进行 GAP异频测量。
其中, 根据所述当前 RSTD同频测量观察窗进行同频测量和根据新的 GAP进行异频测量可以通过现有技术实现, 本发明实施例对此不再详细描 述。 在方法 1中 ,通过对 GAP重新进行配置,以保证当前 GAP与当前 RSTD 同频测量观察窗不存在重叠时间, 使得 RSTD同频测量和 GAP异频测量不 会产生资源冲突, 从而保证 RSTD同频测量和 GAP异频测量的成功。
如图 4所示, 方法 3包括:
C 103 保持所述当前 GAP配置不变。
C 1032、判断所述当前 RSTD同频测量观察窗以及所述当前 GAP的位置 关系。 当符合确定所述 RSTD同频测量观察窗的起始位置处于在所述当前 GAP内, 记为第一位置关系时, 则执行步骤 C 1 033 ; 当确定所述 RSTD同频 测量观察窗的结束位置处于在所述当前 GAP内, 记为第二位置关系时, 则 执行步骤 C 1 034。
C 1033、 将所述 RSTD同频测量观察窗的起始位置修改为所述当前 GAP 的结束位置, 并执行步骤 C 1 035。
C 1034、 将所述 RSTD同频测量观察窗的结束位置修改为所述当前 GAP 的起始位置, 并执行步骤 C 1 035。
C 1035、根据所述当前 GAP和修改后的 RSTD同频测量观察窗在时间上 的先后顺序, 依次进行各自对应的测量。
在方法 3中, 通过将 RSTD同频测量观察窗调整至与 GAP不存在重叠 时间, 为同频测量设置了明确的起始位置和终止位置, 从而避免了用户设 备因为要进行异频测量而在 RSTD同频测量观察窗的时间段内, 不能获取 明确的起始位置或终止位置为导致同频测量的不能开始或者是不能结束, 进而保证 RSTD同频测量的成功。
本发明实施例提供的解决测量冲突的方法, 通过判断所述当前 RSTD 同频测量观察窗与所述当前 GAP是否存在重叠时间, 并在当前 RSTD同频 测量观察窗与所述当前 GAP存在重叠时间时, 按照配置策略进行 RSTD同 频测量和 GAP异频测量, 解决了 RSTD同频测量与异频测量的测量冲突, 从一定程度上保证了 RSTD同频测量的成功。

203、判断 RSTD同频测量对应的 QoS要求的时延等级是否大于第一预 设门限。 若确定所述 RSTD同频测量对应的 QoS要求的时延等级大于第一 预设门限, 则执行步骤 204。 否则执行步骤 205。
其中, 第一预设门限可以根据 QoS中响应时间 Response Time子段来 定义, 响应时间是下面三种枚举类型, no delay, low delay 和 delay tolerant, 可以把门限定义为 low delay, no de lay的时延等级高, delay tolerant时延等级低。
204、 执行实施例 1 中阐述的方法 1。

若确定所述比值等于或小于第三预设门限,则确定所述用户设备在在 所述当前 GAP中非重叠时间内所述用户设备不能够完成异频测量。
其中, 所述第三预设门限, 可以取如 4, 8, 16等整数。 206、 执行实施例 1 中阐述的方法 2。
207、判断所述当前 RSTD同频测量观察窗中非重叠时间内有效子帧数 是否大于第二预设门限。 若确定所述当前 RSTD同频测量观察窗中非重叠 长度内有效子帧数大于所述第二预设门限, 则执行步骤 206。 否则, 执行 步骤 208。
