1. A method for acquiring a Radio Access Technology (RAT) of a serving cell where a relay device is located, comprising:
receiving RAT indication information from the relay device, wherein the RAT indication information indicates RAT information of the serving cell where the relay device is located;
determining, based on the RAT indication information, a RAT type adopted by a base station to which the serving cell belongs; and
communicating with the base station using the RAT appropriate to the RAT type adopted by the base station;
wherein said determining, based on the RAT indication information, the RAT type adopted by the base station to which the serving cell belongs:
comparing system information of the base station with various types of preset standard system information to obtain a comparison result, and determining the RAT type of the serving cell based on the comparison result; and
determining the RAT type adopted by the base station based on the RAT type of the serving cell.
