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.

Abstract: The application discloses a method implemented by a first base station, including: obtaining, first receive power information, where the first receive power information is receive power information of receiving a signal transmitted by user equipment served by a second base station; determining, according to the first receive power information, a relationship between the user equipment and a coverage area of the first base station; and notifying the second base station of the relationship. Thus, when user equipment approaches a network covered by a first base station, a second base station may know a relationship between the user equipment and the coverage area of the first base station, so as to perform a network handover for the user equipment or establish a wireless connection between the user equipment and the first base station. The embodiments of the present invention further provide a corresponding base station.
