WCDMA系统向GSM系统间切换采用 3A 还是 3C 事件?
我要回答
问题答案
同频测量事件1X:
1A:一个主导频进入报告范围, 相对门限增加事件。
1B:一个主导频信道离开报告范围, 相对门限删除事件。
1C:一个不在Active set 里的主导频信道的导频信号强度超过一个在Active set里的主导频信道的导频信号强度, 替换事件。
1D:最好小区发生变化;
1E:一个主导频信道的导频信号强度超过绝对门限值
1F:一个主导频信道的导频信号强度低于绝对门限值
异频测量事件2X:
2b:当前使用频率低于绝对门限, 非使用频率质量高于另一绝对门限。
2c:非使用频率质量高于绝对门限。
2d:使用频率质量低于某一绝对门限,用于启动压缩模式。
2f:当前使用频率质量高于某一绝对门限,用于停止压缩模式。
异系统测量3X:
3a:当前使用频率质量低于某一绝对门限,GSM小区质量高于另一个绝对门限。
3c:Gsm小区质量高于一个绝对门限。
话务量测量事件用4X:
Reporting event 4 A: Transport Channel Traffic Volume becomes larger than an absolute threshold
Reporting event 4 B: Transport Channel Traffic Volume becomes smaller than an absolute threshold
质量测量用5X:
Reporting event 5A: A predefined number of bad CRCs is exceeded
内部测量6X:
Reporting event 6A: The UE Tx power becomes larger than an absolute threshold
Reporting event 6B: The UE Tx power becomes less than an absolute threshold
Reporting event 6C: The UE Tx power reaches its minimum
Reporting event 6D: The UE Tx power reaches its maximum
Reporting event 6E: The UE RSSI reaches the UE's dynamic receiver range
6g:ue下行接受时间和上行发射时间间隔小于绝对门限。
6f:ue下行接受时间和上行发射时间间隔大于绝对门限。
UE位置测量7X:
Reporting Event 7a: The UE position changes more than an absolute threshold
Reporting Event 7b: SFN-SFN measurement changes more than an absolute threshold
Reporting Event 7c: GPS time and SFN time have drifted apart more than an absolute threshold

这个都可以的,你想3A就3A,想3C就3C
不过目前采用的都是3A
其实如果你仔细想,城区用3A,边缘区域用3C,可能效果比较好!
