Document Type and Number:
WIPO Patent Application WO/2022/054383
Kind Code:
A1
Abstract:
[Problem] As the number of data radio bearers increases, the number of DL USER DATA messages also increases, as a result of which a large amount of communication bandwidth in the transmission path is consumed. [Solution] A first message requesting notification of a data transmission status in a plurality of data radio bearers, among first bearers indicating a data radio bearer established with a second communication device, is generated, and the first message is transmitted to the second communication device.
