Abstract: This application provides a data transmission method and apparatus. The method includes: A core network element receives a first message sent by a first terminal device. The first message is used to request to establish a first PDU session. The core network element determines, based on group information corresponding to the first terminal device, that the first terminal device needs to perform local routing. The group information includes a group identifier ID and a group member list. The core network element obtains binding information. The binding information includes the group ID and session information of the first PDU session, and the session information includes one or more of a session ID, a TEID, and a QFIs of the first PDU session. The core network element sends the binding information to a first access network node. This can implement IAB based local routing, and shorten a transmission latency.

Abstract: Embodiments of this application provide a data transmission method and a data transmission apparatus. The method includes: obtaining, by an access management network element, information about a connection status of a terminal device in a first network; and processing, by the access management network element, a data transmission procedure of the terminal device in a second network based on the information about the connection status of the terminal device in the first network. When the terminal device needs to transmit data through both the two networks, the method in the embodiments of this application can avoid a problem that the terminal device overuses a resource in either of the networks.

Abstract: Example authentication methods and apparatus are described. One example method includes receiving access authentication information by an access network element from a terminal device. The access network element generates a first message based on the access authentication information, where the first message includes the access authentication information. The access network element sends the first message to an access management network element, and receives a first response message from the access management network element in response to the first message. The first response message includes response information of the access authentication information. The access network element sends the response information of the access authentication information to the terminal device based on the first response message.
