首先，服务小区主频不需要定义为测量频点。在通话过程服务小区通过测量报告对服务小区及邻区的信号电平及质量进行测量。
serving cells BCCH in active list
这个为手机在通话状态下的测量频率表，在通话过程中对邻区的测量，用于切换。
serving cells BCCH in idle list
这个为手机在空闲模式时的测量频率表，用于在空闲模式时的小区测量，对小区重选起作用。

active 和 idle 不知道的话就看书吧

serving cells BCCH in active list
serving cells BCCH in idle list

这两个选项可都是服务小区的BCCH啊~如果在CNA中勾选这两个选项的话，则在双BA表中就会添加服务小区的BCCH，否则不添加……

平常说的那些邻区六强测量是通过测量频点来进行测量的这个都晓得

只是服务小区的信号强度和质量的测量是通过什么方式来进行测量的？

假设在active list 中添加了BCCH ，邻区同主频，不同BSIC，是否能发生切换？

不明白的东西要顶起~

这么说吧，在一个测量报告里面，首先就有服务小区的信号电平和质量测量，还有包括邻区的测量。所以呢测量报告里面就包含了服务小区和邻区 信号电平和质量的测量。

这个是可以发生切换的，但是前提是在当前服务小区的状态下质量较好，能够正常解出邻区的BCCH/BSIC。但是，邻区间同主频一般会造成好大的干扰，一般不建议邻区间存在同BCCH的情况。

8楼的兄弟，我觉得不太可能切换，因为切换的话目标小区信号强度比服务小区高，他们同频的话那C/I就是负的了，质量是不可能好的，BSIC肯定解不出来

IDLE，必须加测量频点。ACTIVE不需要加，这是协议规范。
4Engineering Guidelines

4.1The Active Mode BA List

The active mode BA list should correspond to the defined neighbors. The BCCH carrier of serving cell should not be in the active mode list. A short active mode BA list gives better handover performance than a long list. If a long active mode list is used there will be less samples taken from each cell, thus resulting in decreased measurement accuracy. It could also be the case that the MSs spends time decoding the BSIC of an irrelevant cell. Furthermore, if this is not successful it will spend extra time trying to decode the BSIC of this cell and waits longer time before it re-decodes the BSICs of the other cells. Thus, this increases the risk that they are no longer valid. The active mode list should, in the normal case, not exceed 15 frequencies.

4.2The Idle Mode BA List

The idle mode BA list should normally correspond to all the BCCH carriers used. Serving cell should be included in the idle mode BA list. When an MS is switched on, the MS scans the latest received BA list. If the MS has moved, it could be the case that the MS measures a very weak signal from one of the cells in the old list, and camps on it. If this list is very short and does not contain the cells which are the best ones in the current location of the MS, the MS will continue to camp on the "wrong" cell. To set up a call under these circumstances is not favorable. This situation can be avoided if the idle mode list contains more frequencies. Many frequencies in the idle mode list means that less samples are taken per frequency than what would have been the case if the list was short. The decreased accuracy for the idle mode measurements that this gives rise to is not considered a problem.

4.3Changing the BA Lists

Changing the list with the default method takes longer time than with the immediate method. Using the immediate updating method the new list is received by the MS within a few seconds, whereas it takes 30 seconds per cell when the default method is used. It is recommended to use the default method when changing the active mode measurement list. Otherwise the measurement reports may be interpreted incorrectly for a short time. Updating of the idle mode list can always be performed using the immediate updating method.

在IDLE下加服务小区的BCCH，主要是为了驻留在当前小区的MS，在关机开机后，读取保存的BA LIST中的BCCH时，可以读到当前小区的BCCH，可以方便选择当前小区。不然就要选到别的地方去，如果MS不移动的话，还要重选或者切换回来，大面积如此的话，增加不必要的网络负担并且容易引起异常事件。

什么是测量频点啊？2G配完邻区后，是不是可以在Mapinfo里个TCH，加的这个TCH频点是不是测量频点？

受教了，一直没看到协议的！
