Step S106, remote radio unit (RRU) reports baseband pool with the receive logic ID that receives, and baseband pool compares receive logic ID and acquisition logic ID, determines whether remote RF unit access according to comparative result.

The authentication information of remote radio unit (RRU) can comprise production firm's information and the sequence number that is stored in advance in the remote radio unit (RRU).

Sequence number can be equipment beacon information or original production information.

Step S102 can comprise: baseband pool compares the production firm's information and the sequence number of the production firm's information in the authentication information of radio frequency unit and sequence number and permission access, if comparative result unanimity then allow remote radio unit (RRU) to insert, otherwise the refusal remote radio unit (RRU) inserts.

Baseband pool can obtain this acquisition logic ID by the physical logic mapping table of remote radio unit (RRU).

Baseband pool can calculate the acquisition logic ID according to physical address information.

Step S106 can comprise: remote radio unit (RRU) is stored receiving logic ID after receiving receive logic ID.

Step S106 can also comprise: if receive logic ID is different with the acquisition logic ID, then baseband pool initialization remote radio unit (RRU) or refusal remote radio unit (RRU) insert.

By technique scheme, realized managing different RRU, prevent that unauthorized RRU from inserting, control diverse location RRU for the RRU that has authorized by logic ID and insert, solve the problem that the RRU physical location change causes in the running.

Other features and advantages of the present invention will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the present invention.Purpose of the present invention and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.
