Background
The existing method for saving energy at the base station side comprises the following steps: in rural areas, mountainous areas, shopping malls and office areas, when the network load is reduced, the base station side mostly adopts the following energy-saving means: and shutting off the multi-layer network carrier and shutting off the channel. The switching off of the multi-layer network carrier means that when the network has a pilot frequency multi-layer network architecture, the base station equipment with a lower frequency band is generally used as a bottom layer coverage network, and when energy-saving working deployment is performed, the carrier with a higher frequency band is switched off; closing channels means that if a Long Term Evolution (LTE) network employs multiple input multiple output (mimo), that is, there are at least 2 or more transmit/receive channels, when traffic load becomes smaller, partial channels may be considered to be closed, and power consumption may be reduced to achieve the purpose of saving energy.
The existing energy-saving measures of the base station have obvious defects: 1) the user perception cannot be guaranteed because the basic covering layer cannot be positioned; 2) the time interval for starting the energy-saving measure is fixedly set, for example, 0-6 days per day, the user requirement in the time interval is assumed to be less artificially, but 0-6 days per day is only the time interval with less traffic under the whole network condition, and the service requirement in the time interval is not necessarily the minimum for a base station or a cell in a local area; 3) the real-time service load of cells with different frequency bands in a multi-layer network is not considered, only the shutdown of a certain layer of network is considered, and the implementation efficiency is not high.
Therefore, how to perform base station energy saving more specifically is a technical problem that needs to be solved urgently by those skilled in the art.

In order to solve the prior art problems, embodiments of the present application provide a base station energy saving method and apparatus, an electronic device, and a computer storage medium. First, a method for saving energy of a base station provided in an embodiment of the present application is described below.
Fig. 1 shows a flowchart of a base station energy saving method according to an embodiment of the present application. As shown in fig. 1, the method for saving energy of a base station includes:

And S104, under the condition that the utilization rate of the physical resource block is determined to be lower than a preset first physical resource block utilization rate threshold, executing user migration operation from the capacity layer cell list to the basic covering layer cell list.
In one embodiment, in a case that it is determined that the physical resource block utilization rate is lower than a preset first physical resource block utilization rate threshold, performing a user migration operation from the capacity layer cell list to the base overlay layer cell list, including:
setting a timer under the condition that the utilization rate of the physical resource block is lower than a first physical resource block utilization rate threshold;
and executing the user migration operation within the period of the timer.
In one embodiment, after performing the user migration operation of the capacity layer cell list to the base overlay layer cell list, the method further comprises:
and executing cell starting operation of the capacity layer cell list under the condition that the physical resource block utilization rate is determined to be higher than a preset second physical resource block utilization rate threshold.
The following describes the above technical solution with a specific scene embodiment.
The method comprises the following steps: collecting MR sampling points of a Long Term Evolution (LTE) network, checking RSRP values of a source cell and an adjacent cell of each sampling point by big data, obtaining cells meeting the requirement of ensuring the basic coverage of a user through calculation, and defining the cells as a basic coverage layer list C1, and defining the cells which are co-located in the same sector in a C1 list as a capacity layer C2;
step 101, collecting an LTE network MR sampling point, mainly collecting Reference Signal Received Power (RSRP) of the MR sampling point, RSRP of a source cell and RSRP of an adjacent cell;
reference Signal Received Power (RSRP), defined as the linear average of the power (W) of the Resource Elements (REs) carrying cell-specific reference signals over the frequency band considered for measurement, is the main indicator reflecting the serving cell coverage. The measurement data represents the number of samples of the reference signal received power of the User Equipment (UE) according to the interval statistics, which meet the value range in the statistic period of the network element management system (OMC-R) of the wireless access network.
The reference signal received power of the LTE serving cell, which reflects the magnitude of the reference signal received power of the serving cell received by the UE, is a main index reflecting the coverage of the serving cell, and represents an original measurement value of the received reference signal power of the LTE serving cell (i.e., a measurement value in a measurement report reported by the Uu port).
The reference signal received power of the LTE neighbor cell reflects the magnitude of the neighbor reference signal received power of a defined neighbor relation and an undefined neighbor relation in a certain serving cell by the UE, and is the main reference for deciding handover.
Step 102, checking the RSRP value of a source cell and an adjacent cell of each sampling point through big data, and calculating to obtain a cell which meets the requirement of ensuring the basic coverage of a user;
in order to facilitate calculation and achieve the purpose of obtaining a basic covering layer closer, MR sampling points with RSRP lower than-100 dBm can be screened, the difference value of the RSRP of a source cell and the RSRP of an adjacent cell is calculated, the source cell is set to be s1, the first adjacent cell is n1, the difference values between s1 and n1 are respectively calculated, and then the average value is calculated;
Average RSRP(s1,n1)＝∑(s1-n1)
the decision average is "positive", i.e. greater than 0, i.e. decision s1 is the base coverage cell in (s1, n 1);
traversing all MR sampling points;
step 103, uniformly defining the calculated basic coverage cells as a basic coverage list C1, and defining the cells co-sited in the same sector in the C1 list as a capacity layer C2.
Step two, obtaining the adjacent cells of each cell in the C1 list through a cell list C1 of a basic covering layer, and judging the real-time loads of the cells and the adjacent cells in the C1 list by acquiring Physical Resource Block (PRB) load statistical data;
step three: setting a PRB utilization rate low threshold T1 configured for a user and ensuring a service rate, starting a C2 cell to transfer the user to a C1 cell when the PRB utilization rate of the cell in a list of C1 and C2 is judged to be lower than T1 at the same time, and turning off the C2 cell after a certain time delay is met;
and step four, setting a PRB utilization rate high threshold T2 configured for the user to ensure the service rate, starting the C2 cell and closing the energy-saving measure when judging that the PRB utilization rate of the cell in the C1 list exceeds T2.
Step 401, setting a PRB utilization rate threshold T2 configured for a user to guarantee a service rate, and implementing step 402 when a cell load of a basic cover layer C1 list becomes large and exceeds a T2 threshold;
step 402, start the C2 cell and turn off the energy saving feature.
Compared with the prior art, the embodiment of the application has the following beneficial effects:
1. the defined basic coverage layer can guarantee the basic coverage requirements of users, and the basic coverage layer is calculated in a big data mode, so that the basic coverage layer is prevented from being defined according to a frequency band mode, and the method is more accurate;
2. by means of the pilot frequency cell message assistance mode of the X2 port, the pilot frequency cell load is judged in real time, the real-time service requirement of a user can be judged, and the user use perception is guaranteed;
3. the PRB threshold setting based on the service rate avoids the mode of judging the energy-saving measures to be turned on or off in a fixed time period, the energy-saving efficiency is higher, and the user perception is guaranteed.
