Abstract: A method includes receiving a first parameter set that is for establishing a relay radio link control RLC bearer and that is sent by a first terminal; and further receiving a first configuration message sent by a network device, where the first configuration message includes a second parameter set corresponding to the relay RLC bearer. The relay device establishes, based on the first parameter set received from the first terminal and the second parameter set obtained from the network device, a relay RLC bearer corresponding to a first link, where the first link is a link between the relay device and a second terminal.

Abstract: Embodiments of this application disclose a communication method and a related apparatus, so that remote UE can communicate with a network via relay UE that resumes or establishes a radio resource control RRC connection, to ensure communication quality of the remote UE. The method includes: A first access network device receives a first message sent by first UE, where the first message includes a first identifier of second UE, and the first identifier is an identifier of the second UE in an RRC inactive state or an RRC idle state. The first access network device pages the second UE based on the first message. The first access network device sends a second message to the first UE, where the second message indicates the first UE to perform path switching, the second message includes a second identifier of the second UE.

Abstract: This application discloses a communication method, including: a terminal obtains a current flight parameter, and determines a target conditional handover configuration from a candidate conditional handover configuration group based on the current flight parameter, where the target conditional handover configuration is used to determine a second cell that the terminal expects to access. In this process, because the candidate conditional handover configuration group generated by the access network device to which a first cell belongs corresponds to the flight-related parameter, the terminal obtains the target conditional handover configuration in the candidate conditional handover configuration group based on a matching result between the current flight parameter and the flight-related parameter. In this way, accuracy of obtaining the target conditional handover configuration is improved, and efficiency of handover to the second cell is improved.

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.
