| 技术特征描述及公开性判断结果 | 对比文件原文引用 | 公开性论述 |
| 技术特征A《直接公开》 | [0030] In the example of FIG. 2A, process 200 begins at process block 201, where the location server determines an estimated position of the mobile device. | 对比文件明确公开了位置服务器确定移动装置的估计位置,该步骤在对比文件中的作用是进行位置估计以开始辅助数据生成过程,与目标专利中确定估计位置以用于后续小区选择的作用相同。 |
| 技术特征B《直接公开》 | [0031] Now having the estimated position of the mobile device within the mobile network, process 200 proceeds to process block 202 where a first set of candidate cells are determined. | 对比文件明确公开了基于移动装置的估计位置确定第一组候选小区。该步骤在对比文件中的作用是生成初始候选集,与目标专利中基于估计位置筛选候选小区的作用相同。 |
| 技术特征C《直接公开》 | [0042] In one aspect, all non-impacted candidate cells will have their threshold sensitivity set at first fixed level (e.g., -124dBm). | 对比文件明确公开了对于未受影响(即以不同频率发射定位信号)的候选小区,将其阈值灵敏度(即预期干扰相关的参数)设置为第一固定电平(如-124dBm)。这对应于目标专利中“设置为默认电平”的技术特征,作用均是设定非干扰小区的基准干扰水平。 |
| 技术特征D《直接公开》 | [0042] Impacted cells (those having the same positioning signal transmit frequency as the serving sector or any other known candidate cells) will have their threshold sensitivity set according to one of the above-mentioned three categories of interference estimates. | 对比文件明确公开了对于受影响小区(即以与服务小区相同频率发射定位信号的候选小区),其阈值灵敏度根据干扰估计类别来设置。这直接对应于目标专利中估计相同频率候选小区的预期干扰的技术特征,作用均是评估同频干扰。 |
| 技术特征E《直接公开》 | [0041] As with position estimation, interference estimation depends upon how much is known at the beginning of the process. For example, to the extent appropriate data are available, the interference estimates will fall into one of the following three categories: Category 1, where the serving power levels of the serving cell are unknown; Category 2, where the serving power levels of the serving cell are known, but the serving power levels of other active cells are unknown; and Category 3, wherein the serving power levels of the serving cell and of other active cells are known. | 对比文件明确公开了干扰估计取决于已知信息,并具体列出了三个类别,其中第一个类别的条件就是服务小区的服务功率电平未知,第二个和第三个类别的条件包含了服务小区的功率电平已知。这直接公开了“确定服务小区的服务功率电平是否已知”这一判断步骤,该步骤在对比文件中的作用是选择不同的干扰估计算法路径,与目标专利中的作用相同。 |
| 技术特征F《直接公开》 | [0043] FIG. 2D is a flowchart illustrating a process 232' of estimating an expected interference for positioning signals from impacted cell in a wireless communications system... [0044] If not, then process 232' proceeds to process block 234. Process block 234 is representative of a Category 1 interference estimate, where, for impacted cells, the threshold sensitivity at multiple serving power levels is estimated. The serving power levels used may be those nominally associated with the locations within the serving cell that are used for this analysis. | 对比文件图2D及相应描述明确公开了在决策块233判断服务小区功率电平未知时(Category 1),执行过程块234,即在多个与服务小区内不同位置相关联的服务功率电平下,估计受影响小区(候选小区)的阈值灵敏度(即预期干扰)。这直接公开了技术特征F,其作用是在服务功率未知时进行多场景干扰估计。 |
| 技术特征G《直接公开》 | [0045] If however, in decision block 233, it is determined that the serving power levels of the serving cell are indeed known, then process 232' proceeds to decision block 235... [0045] In process block 236 the threshold sensitivity on those candidate cells with the same positioning signal transmit frequency as the serving cell are estimated. In one example, the interference sets the threshold sensitivity at 30 dB below the serving power level... | 对比文件图2D及相应描述明确公开了在服务小区功率电平已知的情况下(对应Category 2),对于具有相同定位信号发射频率的候选小区,将其阈值灵敏度(即预期干扰)设置为低于服务功率电平一个值(例如30dB)。这直接公开了技术特征G,其作用是基于已知服务功率设定同频干扰水平。 |
| 技术特征H《直接公开》 | [0034] Next, in process block 204, a subset of candidate cells are selected based, at least, on the estimated expected interferences. | 对比文件明确公开了基于估计的预期干扰从第一组候选小区中选择子组。该步骤在对比文件中的作用是筛选出受干扰影响较小的最佳候选小区,与目标专利中的作用完全相同。 |
| 技术特征I《直接公开》 | [0034] ... the cells with the highest score are added to the assistance data (e.g., process block 205)... | 对比文件明确公开了将具有最高分数的小区添加到辅助数据中,即产生识别所选小区子组的辅助数据。该步骤在对比文件中的作用是生成最终供移动设备使用的辅助数据,与目标专利中的作用相同。 |
| 技术特征J《直接公开》 | [0034] ... and sent to the mobile device (e.g., process block 206) for use in positioning signal measurements. | 对比文件明确公开了将所产生的辅助数据发送到移动装置。该步骤在对比文件中的作用是完成辅助数据的下发,与目标专利中的作用相同。 |
| 技术特征K《隐含公开》 | [0036] FIG. 2C is a flowchart illustrating a process 212' of determining an estimated position of a mobile device in a wireless communications system depending on the information available to the location server. [0037] ... process 212' may begin at decision block 213 where it is determined whether serving power levels of the serving cell are known. If not, then process 212' proceeds to process block 214. Process block 214 is representative of a Category 1 initial position estimate, where the initial position is set to the geographic center of the serving cell. | 对比文件公开了在一种具体实施方式中(Category 1,服务功率电平未知),将移动装置的初始估计位置设置为服务小区的中心。虽然目标专利权利要求中该特征未限定“在服务功率电平未知的条件下”,但本领域技术人员能够从对比文件公开的该具体方案中,毫无疑义地得出“确定服务小区”以及“将估计位置设置为服务小区中心”是确定估计位置的一种可行且具体的实现方式。因此,该技术特征被对比文件隐含公开。 |
| 技术特征L《隐含公开》 | 同上 | 同上。将估计位置设置为服务小区的中心是技术特征K的必然组成部分和结果,因此同样被隐含公开。 |
| 技术特征M《直接公开》 | [0038] If however, in decision block 213, it is determined that the serving power levels of the serving cell are indeed known, then process 212' proceeds to decision block 215... [0038] In process block 216 the estimated maximum antenna range (e.g., Maximum Antenna Range (MAR)) of the serving base station is scaled according to the known relative power of the serving cell. | 对比文件明确公开了在服务小区功率电平已知的情况下(对应Category 2),根据服务小区的已知相对功率来缩放服务基站的最大天线范围(MAR)。这直接公开了技术特征M,其作用是利用已知功率信息更精确地估计基站覆盖范围。 |
| 技术特征N《直接公开》 | [0038] Using this scaled down MAR, process block 217 then sets the estimated position of the mobile device to the center of the serving cell. | 对比文件在公开了缩放MAR之后,紧接着公开了基于该缩放后的MAR将移动装置的估计位置设置为服务小区的中心。这直接公开了技术特征N,其作用是基于调整后的覆盖范围信息确定位置估计。 |
| 技术特征O《直接公开》 | [0039] If both the power levels of the serving cell are known and the power levels of other active cells in the system are known, then decision block 215 advances to process block 218, which represents a Category 3 initial position estimate. In process block 218, the location server performs a Mixed Cell Sector (MCS) solution using the known relative power levels of the serving cell and other active cells. | 对比文件明确公开了在服务小区和其他活动小区的功率电平均已知的情况下(Category 3),位置服务器使用服务小区和其他活动小区的已知相对功率电平执行混合小区扇区(MCS)解决方案来确定估计位置。这直接公开了基于多个小区中每一基站的已知相对功率电平来确定估计位置的技术特征,其作用是实现更精确的位置初始估计。 |
| 技术特征P《直接公开》 | [0031] In one aspect, creating the first set of candidate cells includes determining whether a distance between the estimated position of the mobile device and a cell's base station is within a threshold distance. If the distance is within the threshold distance and if the estimated position of the mobile device is within a maximum antenna range (MAR) of the respective base station then the candidate cell is added to the first set. | 对比文件明确公开了确定候选小区的方法:判断估计位置与基站距离是否在阈值内,以及估计位置是否在相应基站的最大天线范围(MAR)内。这完全覆盖了技术特征P的内容,其作用是基于地理和覆盖范围进行初步筛选。 |
| 技术特征Q《直接公开》 | 同上 | 对比文件明确公开了如果上述两个条件都满足,则将相应小区添加到第一组候选小区。这直接公开了技术特征Q,其作用是构建候选集。 |
| 技术特征R《直接公开》 | [0047] Returning now to FIG. 2B, now with the estimated expected interferences, process 210 proceeds to process block 242 where link analysis is performed. In one embodiment, analysis is performed at multiple (e.g., five) different locations within the serving cell rather than just at the cell center. The expected power for each candidate cell is determined at each of these locations. The signal margin is determined by taking the difference between expected power and the threshold sensitivity for each candidate cell, determined above. | 对比文件明确公开了基于估计的预期干扰(通过阈值灵敏度THRESHOLD_i体现),在服务小区内的多个位置(两个或多于两个)执行链路分析,估计每个候选小区的链路余量(信号余量SM_i)。并且,阈值灵敏度本身是基于干扰估计设置的,而干扰至少部分由第一组中其他候选小区发射定位信号产生(参见[0032]关于同频干扰的描述)。因此,该技术特征被直接公开,其作用是评估候选信号在干扰环境下的强度余量。 |
| 技术特征S《直接公开》 | [0050] Process 210 may then estimate the probability of availability of a candidate cell's positioning signal, by converting the estimated signal margin to a probability. In one embodiment, the probability of candidate cell's positioning signal availability is determined, by default, from the Gaussian CDF function, as stored in a look-up table. | 对比文件明确公开了响应于估计的链路余量(信号余量SM_i),通过将其转换为概率值(P_i),来估计每个候选小区定位信号可用性的概率。这直接公开了技术特征S,其作用是将信号强度量化为可用性概率。 |
| 技术特征T《直接公开》 | [0051] Ambiguities occur when the location server and mobile device cannot distinguish between signals from two different cell antennas using the same PCI. The location server then estimates the potential for this ambiguity (e.g., process block 262) on each candidate cell's PCI... | 对比文件明确公开了位置服务器基于每个候选小区的PCI来估计不明确性(ambiguity)的可能性。这直接公开了技术特征T,其作用是评估因PCI混淆导致测量不可用的风险。 |
| 技术特征U《直接公开》 | [0053] The probability score, P_i, formed with the signal margin from the link analysis is then scaled to get a final measurement availability estimate: A_i = P_i * f_i. In one embodiment the availability estimate A_i is used to score the candidate cells, as in process block 272. | 对比文件明确公开了基于可用性的估计概率(P_i)和不明确性的估计概率(通过影响因子f_i体现,f_i量化了受不明确性影响的服务覆盖区域部分),计算最终可用性估计(A_i),并用该估计对候选小区进行评分。这直接公开了技术特征U,其作用是为每个候选小区计算综合评分。 |
| 技术特征V《直接公开》 | [0053] The candidate cells with the highest score (e.g., A_i) may then be added to the assistance data and sent to the mobile device (e.g., process block 292) for use in positioning signal measurements. | 对比文件明确公开了将来自第一组的具有最高分数(A_i)的那些候选小区添加到辅助数据(即小区子组)中。这直接公开了技术特征V,其作用是根据评分结果选择最优小区子集。 |
