All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application discloses an energy-saving control method based on wireless communication traffic and a wireless network system, which can realize energy conservation and consumption reduction under the condition of not reducing coverage and traffic. The following detailed description is made with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a power saving control method based on wireless communication traffic according to a first embodiment of the present disclosure. Therein, the wireless communication traffic based power saving control method described in fig. 1 is described from the perspective of a wireless network system (also referred to as an MSS system). In the energy-saving control method based on wireless communication traffic depicted in fig. 1, the involved cells may also be understood as base stations (e.g. 5G base stations) or radio frequency units (e.g. 5G radio frequency units). As shown in fig. 1, the method for controlling power saving based on wireless communication traffic may include the steps of:
101. and the wireless network management system searches for the target cell with the current traffic volume lower than the preset minimum threshold value.
In some embodiments, the wireless network management system may search, as the target cell, a cell in which the number of user connections in the current cell is lower than a preset average connection threshold rrc1 (e.g., rrc1 ═ 5), the throughput of the current cell is lower than a preset cell throughput threshold thr1 (e.g., thr1 ═ 100M), the PRB utilization of the current cell is lower than a preset cell PRB utilization threshold PRB1 (e.g., PRB1 ═ 10%), and the number of idle users in the current cell is lower than a preset number of idle users in the cell through traffic statistics. When the current cell user connection number of the target cell is lower than a preset cell average connection number threshold rrc1 (for example, rrc1 is 5), the current cell throughput is lower than a preset cell throughput threshold thr1 (for example, thr1 is 100M), and the current cell PRB utilization is lower than a preset cell PRB utilization threshold PRB1 (for example, PRB1 is 10%), it is indicated that the target cell is a low-traffic cell, and even if the target cell does not work in the current time period, the target cell still does not have a great influence on the system traffic, and power-off energy-saving control can be performed on the target cell.
102. And the wireless network management system searches a plurality of strong coverage adjacent cells of the target cell.
In some embodiments, the wireless network management system may analyze the MR measurement report of the target cell to obtain an average signal level value of the target cell, calculate a signal level difference between the average signal level value of the target cell and the monitored average signal level value of each neighboring cell of the target cell, and determine whether the signal level difference is lower than a preset level difference threshold, if so, use the neighboring cell as a strong coverage neighboring cell of the target cell, thereby obtaining a plurality of strong coverage neighboring cells of the target cell.
If the signal level difference between the calculated average signal level value of the target cell and the monitored average signal level value of each neighboring cell of the target cell is lower than a preset level difference threshold value, it indicates that in the coverage area of the neighboring cell of the target cell, the target cell (belonging to a low traffic cell) will not have a great influence on the coverage of the target area even after being turned off.
103. And the wireless network management system searches a certain strong-coverage adjacent cell with moderate service quantity from the plurality of strong-coverage adjacent cells to be used as a target adjacent cell.
In some embodiments, the wireless network management system may find, from the plurality of strong-coverage neighbors, a strong-coverage neighbor whose current neighbor user connection number is between a preset neighbor average connection number threshold upper limit value rrc2 (e.g., rrc2 ═ 30) and a preset neighbor average connection number threshold lower limit value rrc3 (e.g., rrc3 ═ 6), whose current neighbor throughput is between a preset neighbor throughput threshold upper limit value thr2 (e.g., thr2 ═ 20G) and a preset neighbor throughput threshold lower limit value thr3 (e.g., thr3 ═ 300M), and whose current neighbor PRB utilization is between a preset neighbor PRB utilization threshold upper limit value PRB2 (e.g., PRB2 ═ 80%) and a preset neighbor PRB utilization threshold PRB3 (e.g., PRB3 ═ 25%), as the target neighbor.
The embodiment of the application can find out the strong coverage neighbor cell with proper service volume (the service volume is not high or low, the service volume is too high, congestion can occur in a short time, the strong coverage neighbor cell cannot be used as the target neighbor cell, the service volume is too low, the strong coverage neighbor cell can be a low service cell, and if the strong coverage neighbor cell is locked, coverage of the cell can be influenced) as the target neighbor cell which can be switched to.
104. And the wireless network management system forcibly switches all the users residing in the target cell to the target adjacent cell and locks the target cell to enable the target cell to suspend providing service.
In this embodiment, the wireless network management system may switch the active and inactive user forced command residing below the target cell to the target neighboring cell (if there are multiple target neighboring cells, the active and inactive user residing below the target cell may be allocated to the multiple target neighboring cells according to the traffic proportion), and then lock the target cell, so that the target cell suspends providing services.
As an alternative implementation, after the wireless network management system performs step 104, it may perform traffic statistics on the target neighboring cell, and after the traffic statistics on the target neighboring cell is completed, it is found that the traffic of the target neighboring cell within a specified time (for example, 10 minutes) does not continuously exceed the upper limit of the traffic threshold, and then the wireless network management system performs step 105.
In other embodiments, the wireless network management system may also perform power control on the target cell first, gradually reduce the pilot power of the target cell, and then switch the active and inactive user forced commands residing below the target cell to the target neighboring cell to be forced to switch to the target neighboring cell, so that the traffic volume is more smoothly transitioned between different cells.
105. And the wireless network management system disconnects the direct current air switch accessed by the target cell so as to realize power-off and energy-saving of the target cell.
In some embodiments, the wireless network management system may perform remote control through the moving-ring monitoring system to disconnect the dc air switch accessed by the target cell, so as to achieve power-off and energy-saving of the target cell (this operation is achieved if an intelligent air switch that is remotely controlled by the moving-ring monitoring system is installed at the end of the switching power supply dc power distribution unit of the target cell).
In some special scenes, the traffic volume of the target cell (such as places such as closing at night, shopping malls, libraries, stadiums and the like) is very low or even 0, and the target cell can be controlled in an energy-saving manner through the on-off of a timed alternating current power supply.
It can be seen that implementing the method described in fig. 1 can achieve energy saving and consumption reduction without reducing coverage and traffic.
Referring to fig. 2, fig. 2 is a flowchart illustrating a power saving control method based on wireless communication traffic according to a second embodiment of the disclosure. The energy-saving control method based on wireless communication traffic depicted in fig. 2 is described from the perspective of a wireless network management system (also referred to as MSS system) and a wireless network management system. In the energy-saving control method based on wireless communication traffic depicted in fig. 2, the involved cells can also be understood as base stations (e.g. 5G base stations) or radio frequency units (e.g. 5G radio frequency units). As shown in fig. 2, the method for controlling power saving based on wireless communication traffic may include the steps of:
201. and the wireless network management system searches for the target cell with the current traffic volume lower than the preset minimum threshold value.
In some embodiments, the wireless network management system may search, as the target cell, a cell in which the number of user connections in the current cell is lower than a preset average connection threshold rrc1 (e.g., rrc1 ═ 5), the throughput of the current cell is lower than a preset cell throughput threshold thr1 (e.g., thr1 ═ 100M), the PRB utilization of the current cell is lower than a preset cell PRB utilization threshold PRB1 (e.g., PRB1 ═ 10%), and the number of idle users in the current cell is lower than a preset number of idle users in the cell through traffic statistics. When the current cell user connection number of the target cell is lower than a preset cell average connection number threshold rrc1 (for example, rrc1 is 5), the current cell throughput is lower than a preset cell throughput threshold thr1 (for example, thr1 is 100M), and the current cell PRB utilization is lower than a preset cell PRB utilization threshold PRB1 (for example, PRB1 is 10%), it is indicated that the target cell is a low-traffic cell, and even if the target cell does not work in the current time period, the target cell still does not have a great influence on the system traffic, and power-off energy-saving control can be performed on the target cell.
202. And the wireless network management system searches a plurality of strong coverage adjacent cells of the target cell.
In some embodiments, the wireless network management system may analyze the MR measurement report of the target cell to obtain an average signal level value of the target cell, calculate a signal level difference between the average signal level value of the target cell and the monitored average signal level value of each neighboring cell of the target cell, and determine whether the signal level difference is lower than a preset level difference threshold, if so, use the neighboring cell as a strong coverage neighboring cell of the target cell, thereby obtaining a plurality of strong coverage neighboring cells of the target cell.
If the signal level difference between the calculated average signal level value of the target cell and the monitored average signal level value of each neighboring cell of the target cell is lower than a preset level difference threshold value, it indicates that in the coverage area of the neighboring cell of the target cell, the target cell (belonging to a low traffic cell) will not have a great influence on the coverage of the target area even after being turned off.
203. And the wireless network management system searches a certain strong-coverage adjacent cell with moderate service quantity from the plurality of strong-coverage adjacent cells to be used as a target adjacent cell.
In some embodiments, the wireless network management system may find, from the plurality of strong-coverage neighbors, a strong-coverage neighbor whose current neighbor user connection number is between a preset neighbor average connection number threshold upper limit value rrc2 (e.g., rrc2 ═ 30) and a preset neighbor average connection number threshold lower limit value rrc3 (e.g., rrc3 ═ 6), whose current neighbor throughput is between a preset neighbor throughput threshold upper limit value thr2 (e.g., thr2 ═ 20G) and a preset neighbor throughput threshold lower limit value thr3 (e.g., thr3 ═ 300M), and whose current neighbor PRB utilization is between a preset neighbor PRB utilization threshold upper limit value PRB2 (e.g., PRB2 ═ 80%) and a preset neighbor PRB utilization threshold PRB3 (e.g., PRB3 ═ 25%), as the target neighbor.
The embodiment of the application can find out the strong coverage neighbor cell with proper service volume (the service volume is not high or low, the service volume is too high, congestion can occur in a short time, the strong coverage neighbor cell cannot be used as the target neighbor cell, the service volume is too low, the strong coverage neighbor cell can be a low service cell, and if the strong coverage neighbor cell is locked, coverage of the cell can be influenced) as the target neighbor cell which can be switched to.
204. And the wireless network management system forcibly switches all the users residing in the target cell to the target adjacent cell and locks the target cell to enable the target cell to suspend providing service.
In this embodiment, the wireless network management system may switch the active and inactive user forced command residing below the target cell to the target neighboring cell (if there are multiple target neighboring cells, the active and inactive user residing below the target cell may be allocated to the multiple target neighboring cells according to the traffic proportion), and then lock the target cell, so that the target cell suspends providing services.
As an alternative implementation, after the wireless network management system performs step 104, it may perform traffic statistics on the target neighboring cell, and after the traffic statistics on the target neighboring cell is completed, it is found that the traffic of the target neighboring cell within a specified time (for example, 10 minutes) does not continuously exceed the upper limit of the traffic threshold, and then the wireless network management system performs step 205 again.
In other embodiments, the wireless network management system may also perform power control on the target cell first, gradually reduce the pilot power of the target cell, and then switch the active and inactive user forced commands residing below the target cell to the target neighboring cell to be forced to switch to the target neighboring cell, so that the traffic volume is more smoothly transitioned between different cells.
205. And the wireless network management system remotely disconnects the direct current air switch accessed by the target cell through the dynamic loop monitoring system so as to realize power-off and energy-saving of the target cell.
In some embodiments, if an intelligent idle switch which is connected to a dynamic loop monitoring system and can be remotely controlled is installed at a switching power supply direct current power distribution unit end of the target cell, the wireless network system remotely disconnects the direct current idle switch connected to the target cell through the dynamic loop monitoring system so as to realize power-off energy saving of the target cell.
206. The wireless network management system monitors whether the target adjacent cell meets any one or more specified conditions in a specified condition set, and if the target adjacent cell meets any one or more specified conditions, the direct current air switch accessed by the target cell is switched on to realize power supply to the target cell; and unlocking the target cell to enable the target cell to provide services again.
