COMMUNICATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/140333
Kind Code:
A1
Abstract:
One aspect relates to a communication control method in a mobile communication system that enables a first communication between first remote user equipment and second remote user equipment over a direct link, and a second communication between the first remote user equipment and the second remote user equipment over an indirect link via relay user equipment. The communication control method comprises a step of the first remote user equipment that has established a direct link with the second remote user equipment transmitting a multi-link split bearer establishment request message, including identification information of the relay user equipment, to the second remote user equipment via the direct link. Further, the communication control method comprises a step of the second remote user equipment, after establishing connection with the relay user equipment, transmitting a multi-link split bearer establishment acknowledgement response message including the identification information to the first remote user equipment via the direct link. Moreover, the communication control method comprises a step of the first remote user equipment establishing a connection with the relay user equipment.
