摘要： Communication network techniques may use geographic information to reduce a number of neighboring cell measurements to be taken. Such techniques may be useful, for example, in cell reselection. Problem: a terminal makes measurements of cells in the NCL provided by its serving cell. The terminal may need to measure all cells in the NCL. If there are many cells in the NCL, (1) a given cell may be measured less frequently than is desirable; (2) measurements of a given cell by the terminal may be no longer accurate due to movement of the terminal; (3) measurements may be made for cells that are not realistic candidates for cell reselection or handover; or (4) too many measurements may cause excessive battery drain. These problems are exacerbated in the presence of multi-RATs or smaller cells (e.g. femto). Solution: a terminal receives a Neighbour Cell List (NCL) from its serving base station and may also receive or determine the locations of the neighboring cells in the NCL. The terminal generates a reduced NCL based on the neighboring cells' locations and its own location (including its moving direction). Only cells that are considered as "worthwhile" (e.g. because in the moving direction of the terminal) are then measured.

摘要翻译：通信网络技术可以使用地理信息来减少要采用的相邻小区测量的数量。这样的技术可能在例如细胞重选中是有用的。问题：终端对其服务小区提供的NCL中的小区进行测量。终端可能需要测量NCL中的所有单元。如果NCL中存在许多细胞，（1）给定的细胞可能被测量的频率低于期望值; （2）由于终端的移动，终端对给定小区的测量可能不再准确; （3）可以对不适合小区重选或切换候选的小区进行测量; 或（4）太多的测量可能导致电量过大。这些问题在多RAT或更小的单元（例如毫微微）的存在下更加恶化。解决方案：终端从其服务基站接收相邻小区列表（NCL），并且还可以接收或确定NCL中相邻小区的位置。终端基于相邻小区的位置和其自己的位置（包括其移动方向）生成缩减的NCL。只有被认为是“有价值的”的细胞（例如因为在终端的移动方向）被测量。
