Description
Technical field
The present invention relates to a kind of method switched between field of communication technology more particularly to base station for realizing user equipment (UE) and
Device.
Background technique
It is traditional with macro base station with the deployment of numerous local nodes such as more and more Home eNodeB, Microcell, relaying
Based on the network architecture network architecture that will gradually develop into more type of base station and coexist, and the network for providing more levels covers
Lid.It is a kind of that more evolution are realized by non-ideal link in order to improve the correlated performance under the polymorphic type base station co-existin networks framework
Cooperation/polymerization network architecture is suggested between type base station (evolved NodeB, eNB).Under this architecture, user equipment (User
Equipment, UE) a part of radio bearer (Radio Bearer, RB) manage in master base station (Master eNB, MeNB)
In main plot group (Master Cell Group, MCG), this part RB includes control plane carrying (Signaling Radio
Bearer, SRB) and user plane bearer (Data Radio Bearer, DRB), and main plot (Primary Cell, PCell) has
Physical uplink control channel (Physical Uplink Control Channel, PUCCH).And other the one of same UE
Part is carried on the secondary cell group (Secondary Cell Group, SCG) of prothetic group station (Secondary eNB, SeNB) management
On, and a major-minor cell (Primary Secondary Cell, PSCell) has PUCCH.Since same UE is same under the framework
When in two eNB have a connection, therefore be referred to as dual link (Dual Connectivity, DC) UE.
Macrocell between UE carry out base station handover operation when, if switching target macrocell support dual link behaviour
Make, for target SCG be closed user group (Closed Subscriber Group, CSG) cell or other there may be physics
Cell (Small Cell) situation of layer cell identifiers (physical cell identity, PCI) conflict, current mechanism can
Can will lead to CSG cell accessed caused by UE or the PCI conflict of not permission can not correct selection target node etc., thus shadow
Ring performance of handoffs.
Doubly-linked connection technology is described below.
In a kind of possible multitiered network overlay environment shown in Fig. 1, nonideal number is used between MeNB and SeNB
According to/signaling interface --- Xn interface, UE may be simultaneously operated under MeNB and SeNB.When the UE for being connected to MeNB enters SeNB institute
When the coverage area of corresponding cell, MeNB can consider according to signal strength or load balancing etc., shift the part or complete of UE
Data/the signaling in portion is to SeNB, to obtain the service of SeNB offer.To realize that UE can use the money of MeNB and SeNB simultaneously
It polymerize (inter-eNB polymerization) resource between source and base station.Under the scene, multiple RB of UE can respectively by SCG cell and
MCG cell carries respectively.The RB for being wherein separated to SeNB may include DRB and/or SRB.
Wherein, the signaling of the SCG addition carried out in the dual link operating process carried out when (inter-eNB) switches between base station
Process is as shown in Figure 2.
In conclusion when realizing the handover operation between the base station that macrocell carries out UE according to the prior art, if switching
Target SCG be CSG cell or other there may be PCI conflict Small Cell, then target eNB carry out dual link judgement when,
It may occur be the correct selection target node of the UE caused by CSG cell has accessed the not UE of permission or conflicted as PCI
The problems such as, to influence performance of handoffs.
