TD中后台参数有哪些
拜托哪位大哥帮小弟一下,急需后台一些2/3G切换参数。我记得有RAT频率质量门限,异RAT频率质量门限,小区个性偏移,迟滞量,请问还有哪些呢?顺带告诉我一下3A 3B 3C还有别的哪些都是什么意思。谢谢大哥。
1A:一个主导频进入报告范围
事件1B:一个主导频信道离开报告范围
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
事件1D:最好小区发生变化
事件1E:一个主导频信道的导频信号强度超过绝对门限值
事件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用2X来标识。
Event 2a: Change of best frequency. 最优频率的改变
2B事件:当前使用使用频率质量低于绝对门限,非使用频率质量高于另一绝对门限。
2C事件:非使用频率质量高于一个绝对门限 。
2D事件:当前使用频率质量低于某一绝对门限,用于启动压缩模式。
Event 2e: The estimated quality of a non-used frequency is below a certain threshold
2F事件:当前使用频率质量高于某一绝对门限,用于停止压缩模式。
异系统测量事件用3X标识。
3A事件:当前使用频率质量低于一个绝对门限,而GSM小区质量高于另一个绝对门限
Event 3b: The estimated quality of other system is below a certain threshold
3C事件:GSM小区质量高于一个绝对门限
Event 3d: Change of best cell in other system
话务量测量事件用4X标识。
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标识(As FDD Mode,It's Measurement of Downlink transport channel BLER)
Reporting event 5A: A predefined number of bad CRCs is exceeded
UE内部测量
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 value
Reporting event 6D: The UE Tx power reaches its maximum value
Reporting event 6E: The UE RSSI reaches the UE's dynamic receiver range
6F事件:当UE的下行接收时间和上行发射时间间隔大于绝对门限
6G事件:当UE的下行接收时间和上行发射时间间隔小于绝对门限
UE位置测量
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
异系统切换涉及:1.CS/PS非H/H业务当前使用RSCP质量门限(比如-90dBm),迟滞(比如4,其实为4/2=2),当TD服务小区电平小于-90-2=-92dBm时,才是触发3A事件的必要条件之一;2.异系统切换判决质量门限(比如-85dBm),指的是当GSM信号电平大于该值时,才触发3A条件之一;3.延迟触发时间(比如说1280ms);以上条件同时满足才能触发异系统的切换。
