3GPP测量事件

事件	定义	38.331与36.331定义差异	备注
A1	Serving becomes better than threshold	38.331与36.331定义一样	服务小区质量好于门限。
A2	Serving becomes worse than threshold	38.331与36.331定义一样	服务小区质量差于门限
A3	Neighbour becomes offset better than SpCell	SpCell(38.331) PCell/PSCell(36.331)	SpCell即Special Cell，是PCell和PSCell的合称。邻小区质量比SpCell质量好一定offset
A4	Neighbour becomes better than threshold	38.331与36.331定义一样	邻小区质量好于门限
A5	SpCell becomes worse than threshold1 and neighbour becomes better than threshold2	SpCell(38.331) PCell/PSCell(36.331)	服务小区质量差于门限1同时邻小区质量好于门限2
A6	Neighbour becomes offset better than SCell	38.331与36.331定义一样	邻小区质量比SCell质量好一定offset
B1	Inter RAT neighbour becomes better than threshold	38.331与36.331定义一样	异系统邻区质量好于门限
B2	PCell becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2	38.331与36.331定义一样	PCell质量差于门限1同时异系统小区质量好于门限2。B2的效果类似于A2+B1。
L1	Interference becomes higher than threshold	38.331定义	干扰高于门限
