A method and a related apparatus for interactive cloud radio access network C-RAN user data in the edge region. In some of the possible embodiments of the present invention, determining at least one collaboration site of at least one adjacent C-RAN aiming to C-RAN users in the edge region; interaction controlling data with collaboration site of the adjacent C-RAN; based on the controlled data, establishing a data interactive channel for interacting a first data with the collaboration site of the adjacent C-RAN; and interacting the first data through the data interactive channel and the collaboration site of the adjacent C-RAN, to enable the collaboration site of the adjacent C-RAN and the users in the edge region to interacting a second data based on the controlled data. Based on the above innovative mechanisms, a C-RAN primary site through the establishment of data interactive channel with the adjacent C-RAN collaboration site performs coupled cooperation, such that adjacent C-RAN collaboration site can perform data interaction with users in the edge region, contributing to users in the edge region to get better gain, and improving system performance.
