COMMUNICATION METHOD AND RELATED APPARATUS

A communication method and a related apparatus provide for differences between internal resources of a base station to support different slice service capabilities on a RAN side. In the communication method, when a first distributed unit (DU) sets up a connection to a first central unit (CU) but the first CU does not support a first slice, and a second CU supports the first slice, the first DU may establish a connection to the second CU based on transport layer information of the second CU and an identifier or a name of the second CU, or the second CU may update the connection between the first CU and the first DU to a connection between the second CU and the first DU. A difference between internal resources of a base station can be more fully utilized to support different slice service capabilities on a RAN side and improve flexibility and coverage of providing a slice service for user equipment.
