Abstract: This application discloses an information transmission method in a communication system. According to the method, a master base station sends a request message to a secondary base station for requesting to transfer one or more flows from the master base station to the secondary base station for transmission to a terminal device. The request message carries one or both of identification information of each flow, and information of a data radio bearer (DRB) associated with each flow. The master base station receives a response message from the secondary base station, indicating whether each of the one or more flows is admitted or rejected by the secondary base station. Based on the identification information of the flows, DRBs are mapped to the flows. QoS management of information transmission is more refined, and requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

Abstract: A RAN server, a wireless communications system, and a terminal attach method are provided. The RAN server configured to centrally manage base stations of a plurality of wireless communications standards is introduced, and the RAN server is used as a central node to implement a unified interface to a core network. A base station that is of any wireless communications standard and that is managed by the RAN server may independently provide a data transmission service to a terminal, so that the wireless communications system provided in this application basically does not cause an additional latency. In addition, a TAI unrelated to a wireless communications standard of a base station is carried in an attach request message, an attach accept message, and an attach complete message that are exchanged in a terminal attach process.

Abstract: A communication method, apparatus and storage medium are provided to resolve conflicts between different configurations of a terminal device. A first communication apparatus receives a first message from a network device. The first message includes first configuration information. The first communication apparatus receives or sends a discovery message and performs measurement based on the first configuration information by receiving or sending the discovery message. The measurement is measurement on signal quality of a sidelink between the first communication apparatus and a second communication apparatus. The first communication apparatus sends measurement information of the measurement to the network device.

Abstract: The present disclosure relates to communication methods and network devices. In one example method, a first network device receives a first message sent by a second network device, where the first message is used to notify whether the first network device configures a default data radio bearer (DRB), and the first network device and the second network device are network devices that provide a multi-connectivity service for a same terminal device. The first network device determines, based on the first message, whether to configure the default DRB.
