Abstract: Methods and apparatus for user transfer in a Cloud-radio access network(C-RAN) are disclosed. In an embodiment, a method includes in response to a request for migrating a user from a first user equipment (UE) virtualized network function component (VNFC) to a second UE VNFC, receiving at the second UE VNFC, dynamic context information of packet data convergence protocol (PDCP) layer and radio link control (RLC) layer for data transmission of the user from the first UE VNFC. The method further includes continuing process of the data transmission of the user at the second UE VNFC based on the dynamic context information.
