阿朗的是4个激活集，至少天津是，有次路过用手机看了一眼

这个？没看懂！！！！

等待 高手的 回答啊 。。。

感觉还是模糊，

数据业务激活集一个噢！

激活集（active set）：指UE和小区建立RL连接的小区集。国内所见都是3个，韩国KT的是4个。


监视集（monitor set ）：不采用邻区合并算法的厂家，则是激活集最好小区的邻区；采用邻区合并算法的厂家，则是激活集小区邻区根据一定算法合并而成。两者的最大个数都是31个，均是RNC通过measurement control下发给UE。


检测集（detected set）：因为现在的网络配置里均要求UE上报detected set小区，只要某小区的CPICH Ec/Io大于等于-20dB同时SCH的Ec/Io大于等于-20dB，即可认为是一个detected cell。（这说法没错的，记得是我回答过的，忘了哪个3GPP协议了）。

如果wcdma中开启了DC功能，就是双载小区合并功能，激活集中就会有出现4个SC的现象，但是出现4个的时候一定有两个SC是一样的，这个在任何地方都是一样的，不管国内还是国外，也许个别国家的运营商特别一些。
至于监测集和检测集上面的回答都已经可以解释了，如果楼主还不太明白的话那就是有点儿太较真了，知道监测集和检测集里的小区是怎么回事就可以了，哪些小区作为邻区有用，哪些作为邻区没用，哪些小区是漏配的邻区，哪些是多余的邻区，知道这些就可以了。
我个人觉得是这样的，没有必要把定义背的一字不差，能明确区分就可以了。
希望对LZ有所帮助。

确实比较模糊的概念，楼主理解得不错，学习了

很专业

在网上搜索到的，在3Gpp网站不知道看那个文档。
Active SetMonitored SetDetected Set
The set of radio links simultaneously involved in the communication between a UE and a RBS is called active set. Up to three radio links can be included in the active set. In addition to measuring and evaluating the radio links (or cells) in the active set, the UE also continuously monitors and evaluates the signals from other surrounding cells.
The surrounding cells not part of the active set can either belong to the monitored set or the detected set. The monitored set are together with the active set the cells that the WCDMA RAN explicitly orders the UE to measure on, which normally are the defined neighbors to the cells in the active set (the abnormal case is described in the next paragraph). The detected set contains all cells that the UE detects that are not part of the active or monitored sets.

When the active set contains more than one cell, the monitored set will be a union of all defined neighbor relations for the cells in the active set. Since there is a limit of 32 intra-frequency cells in the active and the monitored sets, all the defined neighbors for all cells in the active set might not fit into the monitored Set. Those that do not are called unmonitored neighbors.

同样进来多了解了解！！

语音业务一般设置3个好像是因为rake接收机是3的原因吧，3收合并...多了能解调吗？希望专家批评指正，以上是个人理解。

很好的资料，谢谢楼主了
