Abstract: Embodiments of this application provide a duplication mode communication processing method in a central unit-distributed unit (CU-DU) architecture. In a possible implementation, in a process of establishing a user plane tunnel between a CU and a DU by exchanging information about uplink tunnel endpoints and information about downlink tunnel endpoints, the DU provides an identity of a primary path to the CU, thereby implementing a duplication mode of a data radio bearer.

Abstract: This application provides a network access method, an access device, and a terminal device. The access device is connected to at least two different types of core networks. When the terminal device is to connect to a core network, the terminal device sends, to the access device, a first message used to indicate a type of the terminal device. The access device determines the type of the terminal device based on the first message, and determines, based on the type of the terminal device, a target core network to be connected by the terminal device, so that the access device accurately connects the terminal device to the target core network.

Abstract: This application provide example mobility management methods, access network control devices, and communications systems. One example method includes receiving, by an access network control device, a location area request message of user equipment (UE) through a first station, where the UE is located in a cell managed by the first station. The access network control device can configure at least one location area identity list for the UE based on the location area request message, where the location area identity list includes at least one location area identity, and the location area identity is used to identify a location area. The access network control device can then send the at least one location area identity list to the UE through the first station.

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.
