Abstract
The present application discloses a method and an apparatus. In the present application, a radio access network RAN server receives a measurement report from a terminal, determines a target inter-RAT cell of the terminal based on the measurement report, and configures a resource for the terminal in the target inter-RAT cell. The configured resource is a resource to be used by the terminal to access the target inter-RAT cell. The RAN server sends a handover command to the terminal. The handover command is used to instruct the terminal to hand over to the target inter-RAT cell, and the handover command carries an identifier of the target inter-RAT cell and information about the configured resource. In this way, when handover is performed between inter-RAT cells, handover can be implemented without across core networks, thereby reducing signaling exchange between a source core network and a target core network.
