Abstract: Embodiments of the present invention relate to a method for obtaining radio capability information of a terminal, a core network entity, a base station, and a terminal. When a first terminal changes from a first communication path for the first terminal to directly access a network to a second communication path for the first terminal to access the network by using a second terminal, the first terminal receives a first message that is sent by a base station to obtain radio capability information of the first terminal; and then sends the radio capability information of the first terminal to the base station, where the radio capability information includes information about a manner of connection between the first terminal and the second terminal and identification information of the second terminal.
