Exemplary, first base station and the second base station can be respectively according to the first predetermined periods, every the first predetermined period Duration counts the RRC functional entity parameters of this base station.First base station and the second base station statistics RRC functional entity parameters mode with And first predetermined period duration, do not influence the embodiment of the present invention and realize effect, it is not limited in the embodiment of the present invention.

S403, first base station are according to the RRC functional entitys parameter of first base station and the RRC functional entity parameters of the second base station Determine the RRC anchor base stations of UE.

Optionally, first base station determines the RRC anchor point bases of UE according to the second predetermined period every the second predetermined period duration Stand.The RRC anchor base stations of UE are used for interacting for base station and UE progress RRC information, when there is downlink RRC information to need to be sent to UE When, downlink RRC information is sent to UE by the RRC anchor base stations of UE.When there is uplink RRC information to need to be sent to base station, UE Uplink RRC information is sent to the RRC anchor base stations of UE.

As shown in Fig. 4-1, first base station is according to the RRC functional entitys parameter of first base station and the RRC functions of the second base station The method that substance parameter determines the RRC anchor base stations of UE, can include S4031-S4034：

S4031, first base station send the first request message to the second base station.

Specifically, the first request message is used for the RRC functional entity parameters of the second base station of acquisition request；Wherein, the second base The RRC functional entitys parameter stood is used to characterize disposal ability and transmission performance of second base station for RRC information.

Optionally, first base station mark, the second Base Station Identification, the RRC of acquisition request can be carried in the first request message The cells such as functional entity parameter type.The reusable existing X2 interface message of first request message, such as RESOURCE STATUS REQUEST message, can also define new X2 interface message, and the embodiment of the present invention does not limit.

S4032, the second base station send the first response message to first base station.

Wherein, the RRC functional entity parameters of the second base station are carried in the first response message.

Optionally, the second Base Station Identification, first base station mark, the RRC of the second base station can be carried in the first response message The cells such as functional entity parameter value.The reusable existing X2 interface message of first response message, such as RESOURCE STATUS UPDATE message, can also define new X2 interface message, and the embodiment of the present invention does not limit.

S4033, first base station are joined according to the RRC functional entitys parameter of first base station and the RRC functional entitys of the second base station The RRC anchor base stations of the definite UE of number.

Specifically, first base station counts the RRC functional entity parameters of oneself, and the second base is obtained from the first response message The RRC functional entity parameters stood, according to the RRC functional entitys parameter of first base station and the RRC functional entity parameters of the second base station Determine the RRC anchor base stations of UE.

Optionally, RRC functional entitys parameter includes RRC process resources occupancy, wireless transmission resources occupancy and transmission Link-quality；The method for determining the RRC anchor base stations of UE is specially：

Calculate the RRC performance factor P of first base station and the second base station respectively according to P=α * H+ β * R+ γ * Q, wherein, α, β, γ is weight coefficient, and alpha+beta+γ=1, H are RRC process resource occupancies, and R is wireless transmission resources occupancy, and Q is transmission link Quality；
