Method for realizing soft handoff based on carrier aggregation technology, base station, and terminal

摘要

A method for implementing soft handover based on a carrier aggregation technology, a base station and a terminal are disclosed. The method is applied in a scenario of complementary carrier coverage, and includes: a terminal and a base station simultaneously receiving and transmitting data through a plurality of cells corresponding to a plurality of member carriers by means of carrier aggregation, wherein one of the plurality of cells is a primary cell, and the rest are secondary cells; according to a measurement result of the terminal, the base station determining to switch one of the secondary cells to be the primary cell of the terminal, and marking the one of the secondary cells as a target secondary cell; and the base station maintaining a service connection between the terminal and the target secondary cell, and notifying the terminal to hand over a control signaling connection to the target secondary cell.
