Statistics shows that traditional macro base station (Macro eNB) single layer overlay network is no longer satisfied people to data industry
Business speed and capacity increasing need.Therefore, 3G (Third Generation) Moblie standardization body (3rd Generation
Partnership Project, 3GPP) mode of layering networking is introduced to solve the problems, such as this, i.e., by hot spot region, family
The small overlay environment such as front yard indoor environment, working environment lays the base station i.e. home base stations (Local eNB) of some low-power, including
The forms such as Home eNodeB (Femto)/micro-base station (Pico)/trunking (Relay), to obtain the effect of cell splitting, so that
Operator can provide more high data rate, more inexpensive business for user.

The NCT(Non-standalone NCT of dependent work), subsequent protocol is also possible to introduce new cell type, for example forbids sky
Not busy state UE(IDLE UE) it is resident, but the cell that permission connected state UE is switched in.
For the cell of Non-standalone NCT, neither permission IDLE UE is resident, and does not allow connected state UE mono-
Solely work, but for standalone cell, support that IDLE UE is resident and connected state UE works independently.Therefore it cuts
When changing, if Target cell is standalone NCT, UE can be directly switch to the Target cell by source base station, still
If it is Non-standalone, then UE directly cannot be switched to the cell.
To sum up, for supporting to carry isolated UE, if the UE moved in macro base station coverage area enters Local
The coverage area of eNB, then separated it is contemplated that enabling carrying, the carrying of UE is transferred to local node transmission as early as possible, with
Achieve the purpose that economize on electricity/reduction interference.Once but UE remove macro base station coverage area, in order to guarantee UE data transmission company
Continuous property, it should execute the switching between Marco eNB in time.But in current mechanism, Marco eNB is received in the measurement of UE
Report can not accurately judge initiate carrying separation or switching.
