Abstract: Embodiments of the present disclosure provide a method for accessing an inter-RAT cell and a related device, and the method includes: sending, by a base station, a first message to a terminal, where the first message is used to instruct the terminal to access an inter-RAT cell, and an LTE cell and the inter-RAT cell are different cells. Beneficial effects are as follows: The first message is sent to the terminal, so that the terminal directly accesses the inter-RAT cell without a need to access the base station. In this way, the terminal does not need to perform a handover procedure, thereby reducing a delay in an access process, effectively ensuring that the terminal can successfully access the inter-RAT cell, and effectively ensuring that a radio access technology new RAT service can be performed between the terminal and a base station of the inter-RAT cell.

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.
