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: This application provides a communication method and apparatus. Before a source terminal establishes a unicast connection to a first target terminal, the source terminal allocates a first identifier to the first target terminal based on a request of a relay terminal, where a bit length of the first identifier is less than or equal to 8 bits. The source terminal sends first data to the first target terminal, where the first identifier is configured in the first data. The relay terminal forwards the first data to the first target terminal for the source terminal based on the first identifier. In the foregoing solutions, the source terminal may send a message to a specific target terminal based on the first identifier and the bit length of the first identifier is less than or equal to 8 bits.
