Abstract
Embodiments of the present invention provide a communication method. The communication method includes: performing, by a terminal, a handover from a source base station to a target base station via an interface between the source base station and the target base station, obtaining, by the target base station, a first security capability, and sending, by the target base station, the first security capability to another base station, to establish dual connections. The source base station does not support the first security capability, and the target base station, the another base station, and a core-network network element support the first security capability. The target base station obtains the first security capability, so that the terminal can establish the dual connections to the target base station and the another base station.
