COMMUNICATION METHOD AND RELATED DEVICE

Embodiments of this application provide a communication method and a related device. In the method, a control plane entity CP sends a first message to a user plane steering function entity USF. The first message includes end user information, and indicates the USF to schedule an end user based on the end user information. Then, the CP determines, based on an identifier of a target UP carried in a first request message sent by the USF, to schedule the end user to the target UP. In other words, a scheduling policy of the end user is determined via the USF. Then, the CP further processes a connection between the end user and the target UP based on the identifier of the target UP, so that the scheduling policy of the end user is determined in a BNG device via the USF. This reduces processing load of the control plane entity CP, and improves communication performance.
