Under this framework, subscriber equipment (User Equipment, UE) a part of radio bearer (Radio Bearer, RB) at dominant base (Master eNB, MeNB) main plot group (the Master Cell Group of management, MCG) on, this part RB comprises that chain of command carrying (is Signaling Radio Bearer (Signaling Radio Bearer, SRB)) and user plane bearer (be Data Radio Bearer (Data Radio Bearer, DRB)), and the main plot of this UE (Primary Cell, PCell) there is Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH).And the auxiliary cell set (Secondary Cell Group, SCG) of other a part of radio bearer of this UE (Secondary eNB, SeNB) management at prothetic group station is upper, and in this SCG, have a special cell(particular cell) there is PUCCH.Because UE under this framework has connection at two eNB simultaneously, be therefore known as dual link (Dual Connectivity, DC).
Figure 1 shows that a kind of possible multitiered network covering scene, wherein, adopt nonideal data/signaling interface Xn interface between MeNB and SeNB, UE may be simultaneously operated under MeNB and SeNB.In the time being connected to the UE of MeNB and entering the coverage of the corresponding community of SeNB, MeNB can be according to the consideration such as signal strength signal intensity or load balancing, shift part or all of data/signaling of UE to SeNB so that UE obtains the service that SeNB provides, thereby realize UE and can use simultaneously the resource of MeNB and SeNB, and (inter-eNB) polymerization between base station.Under this scene, multiple RB of UE can be respectively by the little area carrier in SCGZhong community and MCG.The RB that is wherein separated to SeNB can comprise DRB and/or SRB.
In existing protocol, eNB mainly contains following two kinds of modes for the detection of Radio Link Failure (Radio Link Failure, RLF):
Mode one, eNB report based on UE the information that RLF is relevant, judge whether the UE under certain community RLF occurs.
Under which, in the time that UE detects that following any one situation occurs, think and Radio Link Failure (RLF) detected, and at the follow-up eNB that reports:
1) timer T310 is overtime;
2) random access failure of receiving MAC layer is indicated;
3) maximum retransmission that reaches of receiving rlc layer is indicated.
Now, if the safety of Access Layer does not also activate, UE will discharge RRC and connect, and enter RRC_IDLE state; Otherwise UE initiates RRC connection reconstruction process.
Mode two, eNB realize (as according to certain timer expiry, or according to the maximum retransmission of certain packet etc.) based on self, judge whether the UE under certain community RLF occurs.
For the UE of carrier aggregation, only support at present the wireless link monitoring of UE on PCell, and do not support UE at non-PCell(as SCell) on the monitoring of wireless link, make in the time there is radio link problem on the community of UE at non-PCell, UE is current can not detect this problem fast, therefore, UE still can proceed the transmitting-receiving of wireless signal in the community that radio link problem occurs, and disturbs and extra UE power consumption thereby cause.
