Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the method for controlling energy saving of a base station according to the embodiment of the present invention may include the following steps:
step 101: the method comprises the steps that base station energy-saving control equipment obtains load information of each cell in a cell set;
the set of cells is a set of all cells within the selected geographic area. The geographical area and time period for energy saving processing may be divided as desired. Generally, according to the regional characteristics, base station cells in different regions are loaded in time periods, such as base station cells in business districts and office building districts are loaded in daytime working time periods; in other time periods, the load is small, and energy-saving treatment can be performed. The base station energy-saving control equipment sends request information to each cell in the cell set within a time period in which energy-saving processing is required, and then each cell reports respective load information to the base station energy-saving control equipment according to the request information. The load information may be the number of current network users of the cell, the resource occupation ratio of the cell, and the like.
Step 102: the base station energy-saving control equipment determines the sequence of energy-saving operation of each cell according to the load information;
the base station energy-saving control device may rank the cells according to the load amount, and use a cell order of the load amount from small to large as an order of the energy-saving operation of the cells. For example, suppose that there are 8 cells in the cell set, and the order of the loads from small to large is: cell a, cell B, cell C, cell D, cell E, cell F, cell G, cell H.
Step 103: and the base station energy-saving control equipment indicates each cell to carry out energy-saving operation according to the sequence of carrying out energy-saving operation.
The base station energy-saving control device may sequentially send energy-saving operation instructions to the cells at predetermined time intervals according to the order of performing energy-saving operation to instruct the cells to perform energy-saving operation. If the time interval is 5 minutes, an energy-saving operation instruction can be sent to the cell a at 21 points, when the cell a receives the energy-saving operation instruction, energy-saving judgment is immediately carried out, and whether energy-saving operation is carried out or not is determined according to a judgment result; then, sending an energy-saving operation instruction to the cell B at point 21 and point zero 5, immediately judging energy saving when the cell B receives the energy-saving operation instruction, and determining whether to perform energy-saving operation according to a judgment result; and analogizing in sequence, immediately judging energy conservation until the cell H receives the energy conservation operation instruction, and determining whether to perform energy conservation operation according to a judgment result.
The base station energy saving control device may also send an energy saving operation instruction to each cell, where the energy saving operation instruction includes a time point of performing energy saving operation to instruct each cell to perform energy saving operation at a corresponding time point, where the time point corresponding to each cell is determined according to the order of performing energy saving operation. For example, the time point information carried in the energy saving operation instruction sent to the cell a is 21 points, the time point information carried in the energy saving operation instruction sent to the cell B is 21 points and zero 5 minutes, and so on, and the time point information carried in the energy saving operation instruction sent to the cell H is 21 points and 35 minutes. Thus, cell a will make an energy saving decision at point 21 and determine whether to perform energy saving operation according to the decision result, cell B will make an energy saving decision at point 21 and zero 5 and determine whether to perform energy saving operation according to the decision result, …, and cell H will make an energy saving decision at point 21 and 35 and determine whether to perform energy saving operation according to the decision result.
According to step 103, the cells in the cell set sequentially perform energy saving operations according to the sequence specified by the base station energy saving control device, and after the energy saving operation of a certain cell is successful, the cell is switched to the energy saving mode. And the cell in the energy-saving mode closes the temporarily unnecessary hardware resources, and finishes the energy-saving mode when the cell is switched when waiting for network wakeup or busy idle.
The cell may perform energy saving operation in various ways, and the transfer of the cell load to the neighboring cell is described as follows: the cell compares the load of the cell with the load of the neighboring cells, evaluates whether the neighboring cells can completely accept the load of the cell, if so, the cell transfers the load to the neighboring cells, and after the load of the cell is successfully and completely transferred, the cell enters an energy-saving mode; otherwise, the cell does not perform energy saving operation.
A specific implementation procedure of the base station energy saving control method according to the embodiment of the present invention is given below. Referring to fig. 2, the following steps may be included:
step 201, a network concentration point selects base station cells in an energy-saving processing area and requests load information from the cells;
step 202, reporting load information of the cell to a network concentration point by all cells in the region;
step 203, after the network concentration point collects the load information of all cells in the area, the network concentration point decides the order of the cells in the area to execute the energy-saving operation;
step 204, the network centralized point sends the instruction of energy-saving operation executed by each cell to each cell;
step 205, judging: if the current network has cells needing energy-saving processing, the step 206 is entered if the current network has cells needing energy-saving processing, otherwise, the process is ended;
step 206, the cell starts to make energy saving decision at the designated time point: if the current condition can meet the requirement of energy-saving operation, executing step 207, otherwise, not performing energy-saving operation;
step 207, the cell executes energy saving operation;
in step 208, the cell switches to the energy saving mode, and temporarily unnecessary hardware resources are turned off.
In the above embodiment, the order of performing energy saving operation by the cells is decided by a network concentration point (i.e., a base station control device), so that energy saving operation is not performed simultaneously by each cell, thereby avoiding ping-pong effect in energy saving processing. The network concentration point refers to a higher level network element or entity capable of operating a base station, for example, a Code Division Multiple Access (CDMA) network may be a Base Station Controller (BSC), a UMTS Radio Access Network (URAN) network may be a Radio Network Controller (RNC), and a flat architecture network may be a base station Operation Maintenance Module (OMMB), relative to the base station.

a load information obtaining module 31, configured to obtain load information of each cell in a cell set;
an operation sequence determining module 32, configured to determine, according to the load information, a sequence of performing energy-saving operation on each cell;
an energy saving operation indicating module 33, configured to indicate each cell to perform energy saving operation according to the sequence of performing energy saving operation.
The load information obtaining module 31 may obtain the load information of each cell according to the following manner:

sending request information to each cell in the cell set in the time period;
and receiving the respective load information reported by each cell according to the request information.
The operation sequence determining module 32 may determine the sequence of the energy-saving operations performed by the cells as follows:
and sequencing the cells according to the load capacity, and taking the cell sequence with the load capacity from small to large as the sequence of the energy-saving operation of the cells.
