Abstract: Embodiments of this application relate to a multipath data transmission processing method and a network device. A first network device receives a packet from a first host device, and determines a first connection identifier between the first network device and a second network device based on the packet. The first network device encapsulates the packet based on the first connection identifier. The first network device sends the encapsulated packet to the second network device through one of a plurality of subflows between the first network device and the second network device. According to the embodiments of this application, multipath data transmission is implemented, a data transmission rate is increased, and a host device does not perceive a plurality of paths. The embodiments of this application can be applied to any existing communications system.

Abstract: Embodiments disclose a communication method. The method includes: A first network element obtains a first authentication status of a target network slice of a first terminal device from a data management function network element, where the first authentication status indicates a first authentication result of the target network slice, or the first authentication status indicates that no authentication procedure has been performed on the target network slice. The first network element determines, based on the first authentication status, whether to perform a first authentication procedure on the target network slice. The embodiments of this application further provide a corresponding network element.

Abstract: This application provides a method for allocating an IP address, including: establishing, by a session management network element, a session for a terminal apparatus, where the session is used for transmitting a data packet via a control plane network element; allocating, by the session management network element, an IP address to the terminal apparatus; and sending, by the session management network element, the data packet to the terminal apparatus via a mobility management network element, where the data packet includes the IP address. In a case in which the terminal apparatus can obtain the IP address without establishing an additional connection channel, the terminal apparatus can obtain the IP address more flexibly, and occupation of excessive signaling resources can be avoided.
