Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
Fig. 1 is a flowchart illustrating a multi-layer network shutdown energy-saving method according to an embodiment of the present invention, where the method is performed by a multi-layer network shutdown energy-saving device. The multi-layer network turn-off energy-saving device can be a computer device, a terminal device and the like. The multi-layer network of the embodiment of the invention refers to a plurality of network layers of a cell, and the network layers at least comprise an overlay layer and a capacity layer of the cell. As shown in fig. 1, the method comprises the steps of:
step 110: and acquiring the traffic information and the position information of each cell in a preset time period.
The method comprises the steps of obtaining the service volume of each cell from a network management platform in real time. After the service volume of each cell is obtained, the cells are preliminarily classified according to the service volume of each cell, and the low-service-volume cell is determined according to the service volume and the service volume threshold. In the embodiment of the present invention, a specific numerical value of the traffic threshold is not specifically limited, for example, the traffic threshold may be 200, and a cell in which the number of current network users is lower than 200 is determined as a low traffic cell.
Step 120: and determining the same-coverage sector cluster of each cell according to the position information.
After the location information of each cell is obtained, the physical station corresponding to each cell may be determined according to the location information.
The location information includes longitude and latitude of cells, and the specific method for determining the physical station corresponding to each cell includes:
the minimum longitude and latitude of the cell longitude and latitude of the same physical station number (physical cell number) is used as the base station longitude and latitude. Specifically, the longitude and the latitude of the cell of the same physical station number are summed to obtain the sum of the longitude and the latitude. And determining the longitude and latitude of the cell with the minimum sum of the longitude and latitude in the same physical station number as the longitude and latitude of the base station. And when the longitude and latitude of the cell with the minimum sum of the at least two longitudes and latitudes exist, determining the longitude and latitude of the cell with the minimum sum of the at least two longitudes and latitudes, and using the longitude and latitude of the cell with the minimum sum of the at least two longitudes and latitudes as the longitude and latitude of the base station.
Because the physical station number is fixed and the central longitude and latitude corresponding to the physical station number is fixed, each time a circle is drawn by taking a first preset distance as a radius according to the central longitude and latitude, the stations in the circle are counted as a physical station, a single logical station can only be assigned to one physical station and cannot be repeatedly calculated, and therefore the physical station to which each cell belongs is determined. I.e. which cells are under the same physical station is determined in the manner described above. Wherein, the first preset distance may be 50 cm.
After the physical station to which each cell belongs is determined, judging the same-coverage sector of the whole network base station, and specifically determining the same-coverage sector cluster of each cell through the minimum included angle iterative aggregation under the physical station. The method comprises the following steps:
the cells under the same physical station are ordered sequentially according to azimuth angles, specifically, the ordering may be from small to large, starting from 0 degrees, for example: A. b, C, D, E, F, G, H, I;
sequentially solving azimuth angle difference values between the azimuth angles of all the cells, such as A-I, B-A, C-B, D-C, I-H;
combining the two cells with the minimum azimuth difference value into a sector; specifically, from 0 degree, the azimuth angle difference is the smallest, and the two cell azimuth angles are averaged ((a + B)/2), and combined into sector a, and the azimuth angle average corresponding to sector a is determined. And a decimal point is reserved in the calculation process, and no rounding operation is performed.
And sequencing the sectors serving as new cells and the rest cells according to azimuth angles, and performing the step of calculating the azimuth angle difference value of each cell and combining the two cells with the minimum azimuth angle difference value into one sector until the azimuth angle difference value between the cells is greater than a first preset difference value, so as to obtain the same-coverage sector cluster of each cell. The first preset difference may be 30 degrees.
After all aggregated cells are aggregated into sectors, each sector is named (e.g., according to physical station number-1, 2, sequential reference number), and the mean azimuth (rounded up by the virtual azimuth) of each sector is presented in an output detail table. All cells can only belong to one physical sector and can not be repeatedly calculated.
Step 130: and determining the user service quality of the same covered sector cluster corresponding to each cell.
In the embodiment of the present invention, on the premise of the QoS factor, after the network layer of a certain cell is closed, if the user QoS is affected, the network layer corresponding to the cell cannot be closed.
Specifically, the method comprises the following steps:
calculating the receiving power of the first user for receiving the f-layer frequency band signals from each base station:
in the embodiment of the present invention, it is assumed that the first user k is located in an overlapping coverage area of N' base stations (i.e., a same coverage sector cluster), and the type of the overlapping coverage area where the first user is located is determined by combining background data and the position of the first user, so as to determine whether the first user is a local station multi-layer network cell or an adjacent station multi-layer network cell. The received signal vector y for the first user kn,f,kCan be expressed as:
wherein h isn,f,k∈C1×MIs the channel vector, σ, of the first user k2Is Gaussian white noise, xk∈CM×1Precoded signal for a first user k, xl∈CM×1Is the pre-coded signal of the first user l.
Under the condition of considering large-scale fading, determining a channel vector of a first user k in the same-coverage sector cluster according to the received power:
wherein h isn,f,k∈C1×MIs the channel vector for the first user k,
and receiving the received power of the f-layer frequency band signal from the n-th base station for the first user k.
The inter-user interference is eliminated by Zero-Forcing (ZF) precoding, i.e.:
xk＝vksk
wherein v iskIs the precoding vector, s, of user kkA signal is transmitted for the user. For vkUsing joint channel hkPerforming precoding to calculate a precoding vector vkFirst, it is necessary to channel hkCarrying out normalization processing, namely:
gk＝hk/||hk||
vk＝gk'*inv(gk*gk')
wherein, | | hkI is the solving vector hkEuclidean norm of gkIs' gkThe transposing of (1).
Therefore, the channel vector h of the first user k is known to the transmitting endn,f,kReceiving the signal toQuantity yn,f,kAnd transmit signal vector xkBy the above formula, the channel vector h for the first user k can be determinedn,f,kPrecoding vector v of the first userkAnd noise. Thus, the signal-to-noise ratio SINR is calculated from the channel vector, the precoding vector and the noise of the first usern,f,kThe formula is as follows:
and when the signal-to-noise ratio is greater than or equal to the signal-to-noise ratio threshold value, determining that the base station meets the service quality of the first user. Namely: when the cell satisfies the condition SINRk≥SINRl,
Then, the cell is determined to be the serving cell. In the embodiment of the invention, the signal-to-noise ratio threshold SINRlTypically 10 dB.
Step 140: and determining a plurality of turn-off cells and a plurality of service cells according to the user service quality and the service volume information in a preset time period.
Determining each low traffic cell according to the fineness of the traffic, determining whether the low traffic cell is a serving base station according to the service quality of a user, that is, when a network layer corresponding to the low traffic cell is closed, the service quality of the low traffic cell is greatly influenced, that is, when the current signal-to-noise ratio corresponding to the user in the low traffic cell is less than the signal-to-noise ratio threshold, the low traffic cell should not be closed, and determining that the low traffic cell is the serving cell. Namely, the serving base station is determined from the same-coverage sector cluster, and the rest cells are the cells which can be switched off, so that the cell cluster which can be switched off and the serving cell cluster are obtained.
Step 150: traversing the multiple turn-off cells and the multiple service cells according to an energy loss objective function, and determining a target turn-off cell, a turn-off network layer of the target turn-off cell and a target service cell when the energy loss objective function is minimum; wherein the energy loss objective function characterizes a relationship between the energy loss and the turn-off or turn-on of each cell.
Wherein the energy loss objective function is:
wherein, Ptx-maxFor maximum transmitting power, t is any time point in a preset time period gamma, PBSFor accumulated base station energy loss, P, over a preset time period ΓBS,tFor the energy loss of the base station at the t-th time slot, Pt,fWhich represents the transmit power of the t-th slot of the base station on frequency band f. The energy loss objective function represents the relation between the energy loss and the turn-off or turn-on of each cell.
Therefore, according to the energy loss objective function and the constraint condition, the target shutdown cell, the shutdown network layer of the target shutdown cell, and the target serving cell that minimize the energy loss objective function are determined from each of the shutdown cells and the plurality of serving cells.
In the embodiment of the present invention, before step 150, a step of determining a networking architecture is further included. The existing networking architecture is divided into two networking architectures, namely, Non-standard Networking (NSA) and independent networking (SA). Because the 5G network should have a binding relationship with the FDD1800 under the NSA architecture, it is necessary to determine whether the 5G network needs to be turned on before turning off the network layer, and if the 5G network needs to be turned on, the anchor network, such as the FDD1800 network, cannot be turned off. That is, when it is determined that the networking architecture of each cell is the NSA architecture, it is determined whether 5G needs to be turned on, and if yes, the anchor point network of the NSA architecture cannot be determined as the turn-off network layer.
Step 160: and closing the shutdown network layer corresponding to the target shutdown cell.
After a target shutdown cell, a shutdown network layer of the target shutdown cell and a target serving cell are determined, the target serving cell is set as the serving cell in the preset time period, and the shutdown network layer of the target shutdown cell is closed, so that the energy consumption is minimized while the service quality is ensured, and the purpose of energy conservation is achieved.
In this embodiment of the present invention, after the network layer corresponding to the target shutdown cell is closed, the method further includes:
acquiring the current traffic of the same-coverage sector cluster corresponding to the target turn-off cell;
and when the current traffic of the same-coverage sector cluster is larger than a first threshold value, awakening the target shutdown cell.
By the method, the cell traffic can be monitored in real time, when the current traffic of the same coverage sector cluster is overlarge, the target turn-off cell is awakened, the serving cell and the turn-off cell are determined again according to the steps, and the target turn-off cell is dynamically adjusted, so that the purposes of balancing the traffic, the service quality and the energy consumption and dynamically saving energy in real time are achieved.
The method comprises the steps that a plurality of cells capable of being turned off are determined by obtaining service volume information of preset time periods of all the cells and user service quality of a same covered sector cluster; and traversing the multiple turn-off cells according to the energy loss target function, and determining the target turn-off cell and the turn-off network layer of the target turn-off cell when the energy loss target function is minimum, so that the beneficial effects of dynamically turning off the network layer and realizing real-time dynamic energy saving are achieved.
