Fig. 4 shows a kind of schematic flow sheet of controlling little base station operating state that the embodiment of the invention one provides, and particularly, as shown in Figure 4, controls the process of little base station operating state, mainly may further comprise the steps:

Step 401, obtain the downstream signal between terminal communication module corresponding to little base station each macro base station adjacent with little base station, and determine the quality information of each downstream signal.

In this step 401, be used for obtaining downstream signal, and determine that the equipment of the quality information of downstream signal can be for being arranged on the terminal communication module in the little base station, also can be for being arranged on the terminal communication module outside the little base station; The downstream signal that the downstream signal that obtains sends for each macro base station adjacent with little base station, this downstream signal can be sent to for each macro base station the downstream signal of each terminal in the little base station coverage area, also can be sent to for each macro base station the downstream signal of designated terminal in this zone, perhaps, that each macro base station is sent to the downstream signal that this little base station needs this little base station to transmit, in the practical application, the terminal communication module can be obtained above-mentioned downstream signal, the quality information of the downstream signal that sends with each macro base station of determining to occur in the little base station coverage area is namely determined the quality information of the downstream signal between terminal communication module each macro base station adjacent with little base station.In addition, the terminal communication module corresponding with little base station, in the practical application, can be for being arranged on the terminal communication module in the little base station, also can for be arranged on outside the little base station and with the terminal communication module of distance in setting range of little base station.The terminal communication module that occurs in this programme can arrange the terminal communication module that arranges in arbitrary mode of terminal communication modular manner for above-mentioned two kinds.

Step 402, the quality information of the downstream signal determined is reported to equipment of the core network.

In this step 402, be used for reporting the equipment of quality information of downstream signal the same to equipment of the core network, can be for being arranged on the terminal communication module in the little base station, also can be for being arranged on the terminal communication module outside the little base station.

Step 403, send upward signal to adjacent with little base station each macro base station.

In this step 403, the same step 401 and step 402, the equipment that sends upward signal to adjacent with little base station each macro base station can be for being arranged on the terminal communication module in the little base station, also can be for being arranged on the terminal communication module outside the little base station.In the practical application, can preserve the information of each adjacent macro base station in the little base station, for example, with the sign of each adjacent macro base station respectively corresponding other information relevant with each macro base station be kept at this locality, call for the terminal communication module, perhaps, directly with the sign of each macro base station respectively corresponding other information relevant with each macro base station be kept in the terminal communication module, so, the information of the macro base station that the terminal communication module can be directly preserved according to this locality sends upward signal to the macro base station of correspondence, further, can be according to the information of each macro base station of preserving, the macro base station of the downstream signal that sends and receives in the step 401 is identified.

Step 404, macro base station receive upward signal, and determine the quality information of the upward signal of reception.

Step 405, macro base station are sent to equipment of the core network with the quality information of upward signal.

So far, macro base station and terminal communication module have been finished the operation of carrying out in the process of the little base station of control operating state, wherein step 401 to step 402 and step 403 to the order of step 405 execution can be carried out flexibly according to actual conditions, for example, execution in step 401 to the process of step 402 execution in step 403 to step 405, perhaps, after execution in step 403 again execution in step 401 to step 402, this execution in step 401 to the process of step 402 simultaneously execution in step 404 to step 405, perhaps, according to actual needs, adopt other execution sequence, or step 401 to step 402 and step 403 to step 405 carried out according to setting means separately respectively.The executive mode of step 401 to step 402 and step 403 to step 405 can arrange according to actual needs flexibly, exemplifies no longer one by one herein.

The quality information of the downstream signal between step 406, equipment of the core network receiving terminal communication module each macro base station adjacent with little base station, and the quality information of upward signal.

In this step 406, the time of the time of the quality information of equipment of the core network reception downstream signal and the quality information of reception upward signal is the time that receives in the reality, the counterpart terminal communication module reports the time of the quality information of time of quality information of downstream signal and macro base station reporting uplink signal by macro base station respectively, therefore, equipment of the core network might not be the quality information of the downstream signal that receives simultaneously and the quality information of upward signal.In addition, corresponding step 402, the quality information of the downstream signal that equipment of the core network receives is the quality information of the downstream signal that reports of terminal communication module, corresponding step 405, the quality information of the upward signal that the quality information of the upward signal that equipment of the core network receives reports for each macro base station adjacent with little base station.In the practical application, can preserve the corresponding relation of little base station and adjacent each macro base station in the equipment of the core network, so that equipment of the core network can be according to the corresponding relation of preserving, after the quality information of the quality information of the upward signal that receives and downstream signal is processed, send indication information to corresponding little base station.

After the condition that downlink signal quality between step 407, equipment of the core network at least one macro base station in determining terminal communication module each macro base station adjacent with little base station and the little base station of the satisfied control of quality of uplink signal stop to serve, indicate little base station to stop to provide service to each terminal of overlay area.
