Method and device for enabling subordination base station to provide service

The invention discloses a method and device for enabling a subordination base station to provide service. The method comprises: information sent by a terminal may be received by the subordination base station, wherein the subordination base station or other network elements related with the subordination base station determines whether to allow the subordination base station to provide service to the terminal according to the receiving situation of the information; a reference signal may be sent also by the subordination base station; and the terminal, after receiving the reference signal, gives a feedback about information and/or location information obtained based on the reference signal to the subordination base station or the other network elements related with the subordination base station. By using the method and device provided by the invention, the coverage scope of the terminal in the subordination base station can be discovered in a rapid and high-efficient manner.
