The invention discloses a dual-connectivity secondary evolved node B adding method, a dual-connectivity secondary evolved node B adding device and the evolved node B; multiple candidate SeNB (secondary evolved nodes B) are optimally selected and added in a long-term evolution communication system. A master evolved node N obtains secondary cells of the candidate secondary evolved nodes B, secondary evolved node cell B load information and/or user equipment UE velocity information and secondary cell type of the secondary evolved node B, filters the secondary cells of the candidate secondary evolved nodes B and ranks the filtered the secondary cells of the secondary evolved nodes B on basis of priorities; the master evolved node B selects one or more secondary cells of the secondary evolved nodes B from the priority-ranked the secondary cells of the secondary evolved nodes B as target secondary evolved nodes B and transmits request messages to the one or more target secondary evolved nodes B to realize additions of subsequent secondary evolved nodes B. According to invention, the SeNB is optimally selected according to SeNB resource status information and/or UE velocity information, so that E-RAB (Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network Radio Access Bearer) can obtain the best service in the SeNB, thereby improving the user experience; meanwhile, the SeNB addition flow is performed to reduce SeNB addition time delays.

The invention discloses a cell switching method which comprises the steps that: a source base station reserves a dedicated random access resource for user equipment and configures the reserved dedicated random access resource for the user equipment; when the user equipment is switched a target base station, the target base station does not request a core network to convert a downlink GTP tunnel in a preset waiting time; when the user equipment needs to switch to the source base station back, the user equipment uses a stored dedicated random access preamble to initiate random access and carries out synchronization with the source base station, and switches back to the source base station; when the user equipment switches back to the source base station, the source base station removes the dedicated random access resource, carries out admission control and configures distributed wireless resource information to the user equipment. Through the cell switching method provided by the invention, the switching time delay can be reduced, the risk of UE dropping switching process can be reduced, and the signaling processing cost of the base station and the core network can be reduced.
