The cell enhancing that ground is wirelessly electrically accessed the UMTS Terrestrial Radio Access Network network (E-UTRAN) of (E-UTRA) and evolution will concentrate
The additional function of enhancing performance in the hot spot region using the indoor and outdoors of low power nodes.
For one of the potential solution of cell enhancing, dual link has been discussed.Dual link be used to refer to
Fixed UE consumption is by the operation of the radio resource provided from at least two different nexus that non-ideal backhaul is connected.This
Outside, each eNB involved in the dual link for UE can undertake different effects.These effects need not necessarily depend on eNB's
Power grade and it can change between UE.Dual link can be one of the potential solution for cell enhancing.
In existing 3GPP LTE network, SeNB(secondary eNB) adding procedure is by MeNB (Master eNB)
It initiates and be used to establish the connection with UE at SeNB, in order to which UE will be supplied to from the radio resource of SeNB.
This process be used at least add the first community (PSCell) of SCG.

Also targetedly differentiation is not carried out to different connection attributes to handle.
And in 5G environment, since the deployment of MeNB and SeNB are more complicated, switching of the mobile terminal between a variety of eNB
Also more complicated.For example, the connection established for the first time is often of less demanding in timeliness to the demand of dual link, and for switching
Requirement from the connection of other MeNB to timeliness is higher.Original design has been difficult to meet demand.It is badly in need of a kind of new add
Add the scheme of SeNB to adapt to new demand.
It requires to distribute a SeNB, entire assigning process again for the UE after MeNB in any UE connection in the prior art
Program is complicated, and delay is bigger, is easy the data transmission generation pause and transition in rhythm or melody sense so as to UE, influences data transmission quality.
