Handover method and apparatus

A method of a base station, the method comprising:

• transmitting, to a terminal, measurement configuration information including measurement report event configuration information;
• transmitting measurement prediction configuration information to the terminal;
• receiving, from the terminal, a measurement prediction report including measurement prediction results generated based on the measurement prediction configuration information;
• and
• transmitting a handover command to the terminal based on the measurement prediction results.

A terminal comprising at least one processor, wherein the at least one processor causes the terminal to perform:

• receiving measurement configuration information from a base station;
• receiving measurement prediction configuration information from the base station;
• receiving measurement prediction report event configuration information from the base station;
• performing measurement on a serving cell and neighboring cells based on the measurement configuration information to generate measurement results;
• performing measurement prediction on the serving cell and the neighboring cells based on the measurement prediction configuration information to generate measurement prediction results;
• determining whether a measurement prediction report is required based on the measurement prediction results according to the measurement prediction report event configuration information;
• and
• transmitting, to the base station, a measurement prediction report including the measurement prediction results based on whether the measurement prediction report is required.
