Method, equipment and system for handing over cell in communication system supporting carrier aggregation

An electronic device, comprising:

• circuitry including a processor and a memory, and configured to
• configure a terminal device on measurement;
• obtain a measurement report of the terminal device based on the configuration, the measurement report comprising measurement results of one or more measurement objects triggered based on a comparison of performance of the one or more measurement objects with performance of one or more serving carrier frequencies aggregated with a primary carrier frequency of the terminal device based on a carrier frequency of the measurement objects to be measured;
• determine one or more target carrier frequencies for the terminal device based on the measurement report;
• generate a request message for a target node, the request message comprising information of the one or more target carrier frequencies;
• and obtain a acknowledge message from the target node and generate a radio resource control message for reconfiguring radio resource control connection of the terminal device based on the acknowledge message, wherein the measurement report further comprises the measurement results of the one or more measurement objects based on a comparison of the performance of the measurement objects with performance of the primary carrier frequency of the terminal device which based on carrier frequency of the one or more measurement objects to be measured, and the one or more target carrier frequencies comprising a target primary carrier frequency to replace the primary carrier frequency for the terminal device.

A communication method, comprising:

• measuring performance of one or more measurement objects based on a configuration set by a serving node of the electronic device to obtain measurement results, the one or more measurement objects corresponding to one or more neighbour carrier frequencies;
• comparing the measurement results of the measurement objects with performance of one or more serving carrier frequency aggregated with a primary carrier frequency of the electronic device based on carrier frequencies of the measurement objects to be measured;
• comparing the measurement results of the measurement objects with performance of the primary carrier frequency of the electronic device based on carrier frequency of the measurement objects to be measured;
• and triggering a measurement report to the serving node of the measurement results based on the comparisons performed by the circuitry of the measurement results of the measurement objects with performance of one or more serving carrier frequency aggregated with the primary carrier frequency of the electronic device based on carrier frequencies of the measurement objects to be measured, and the measurement results of the measurement objects with performance of the primary carrier frequency of the electronic device based on carrier frequency of the measurement objects to be measured.
