Fig. 2 shows a flow diagram of a power coordination method according to another embodiment of the invention.
As shown in fig. 2, a flow of a power coordination method according to another embodiment of the present invention includes:
Whether downlink transmission power scheduling needs to be carried out on each cell in the cluster can be detected in a circulating mode, the circulating preset detection period can be any period automatically set according to the historical communication condition or the communication importance level of the cluster, and can be 15 min. And a plurality of base stations form a cluster, and one power coordination device can coordinate the power of a single cluster or coordinate the power of a plurality of clusters simultaneously. The PRB refers to a resource which is a time slot (half a subframe, 0.5ms) in the time domain, and the higher the utilization rate of the downlink PRB of the cell is, which indicates that the more the communication behavior of the cell is, the more busy the cell is, the more the downlink transmission power is required. And uniformly adjusting the downlink transmitting power of the cells under different base stations through the power coordination equipment.
In the same predetermined detection period, the detection can be performed at predetermined time intervals, the total amount of detection is a preset first predetermined number of times, the predetermined time intervals and the first predetermined number of times can be any size automatically set according to the historical communication conditions or the communication importance levels of the cluster, the predetermined time intervals include but are not limited to 5min, and the first predetermined number of times include but are not limited to 3 times.
The second predetermined number of times may be any size automatically set according to the historical communication situation or the communication importance level of the cluster, including but not limited to 3 times, and the first predetermined threshold is the lowest downlink PRB utilization rate that has reached the power coordination requirement.
If the utilization rate of the downlink PRB of any cell in the designated cluster is greater than or equal to a first preset threshold value in 3 times of detection of 5 min/time, the number of PRBs of the cell is insufficient, the actual downlink transmission power can not meet the actual communication requirement, and at the moment, a power scheduling mode needs to be started for each cell in the cluster so as to further distribute reasonable downlink transmission power for each cell.
And step 208, obtaining the user equipment communication information from the base station.
Wherein the user equipment communication information comprises: RSRP (Reference Signal Receiving Power) measurement information, MCS (Modulation and Coding Scheme) measurement information, Resource Block (RB) utilization, and user rate. The RSRP in the LTE network may represent the wireless signal strength, which is an average value of signal powers received on all resource particles carrying reference signals, and may determine the actual transmit power of a cell under the base station through RS information, while the MCS measurement information represents a physical transmission rate, and may determine the total amount of resources actually required to be transmitted in the time domain of each cell under the base station, that is, the actual load amount of each cell, through the RSRP measurement information, the MCS measurement information, the utilization rate of the cell RB, and the user rate.
The actual load capacity of each cell is in direct proportion to the required downlink transmission power, so that the proportion of the actual load capacity of each cell to the total load capacity in the designated cluster can be calculated, and under the condition of ideal power distribution, the proportion is equivalent to the proportion of the downlink transmission power configured by each cell to the total downlink transmission power, therefore, the downlink transmission power with the proportion can be configured for each cell in the total downlink transmission power, and the downlink transmission power can be used as final cell power scheduling information, so that the downlink transmission power of each cell can be adapted to the actual communication requirement of the cell.
Finally, the cell power scheduling information is sent to the base station, and the base station configures downlink transmission power for each cell supported by the base station according to the actual downlink transmission power required by each cell under the base station indicated in the cell power scheduling information, that is, the power coordination device performs power repartitioning, and the base station is the main body that allocates different powers for each cell according to the repartitioning result.
Through the technical scheme, the downlink transmitting power of each cell can be reasonably adjusted and redistributed in the time domain aiming at the downlink channel according to the actual communication requirement of the user equipment in each cell, the actual communication requirement can be adapted to the maximum extent, the interference among the cells is reduced, the channel quality and the network performance are improved, and the user internet experience is improved.
In the embodiment shown in fig. 1 and 2, optionally, the method further includes: and under the power scheduling mode, responding to the fact that the utilization rate of the downlink PRBs of all the cells in the designated cluster is smaller than a second preset threshold value, and exiting the power scheduling mode.
That is to say, the second predetermined threshold is the lowest downlink PRB utilization ratio exceeding the actual communication capability of the cell, and if the downlink PRB utilization ratios of all the cells in the designated cluster are all lower than the second predetermined threshold, it indicates that all the cells in the designated cluster are not overloaded for communication and all have reasonable downlink transmission power, so power coordination is not required, and the power scheduling mode can be exited.
Wherein the ratio of the second predetermined threshold value to the first predetermined threshold value is a predetermined percentage, and the predetermined percentage is less than 1. The predetermined percentage may be set to any value that meets the actual communication needs, and may optionally be 0.9.
Further, in another implementation manner of the present invention, in response to that, in the detection of the downlink PRB utilization rates of all the cells in the designated cluster for a third predetermined number of times, the number of times that is smaller than the second predetermined threshold reaches a fourth predetermined number of times, the power scheduling mode is exited.
That is, to ensure that the power scheduling mode is indeed exited under the condition that all cells are not overloaded for communication, the downlink PRB utilization rates of all cells in the designated cluster may be detected for a third predetermined number of times, and if the downlink PRB utilization rates of all cells in the designated cluster for a fourth predetermined number of times are all smaller than a second predetermined threshold value in the third predetermined number of times, it is considered that all cells in the designated cluster are at a relatively stable and reasonable downlink transmission power level, the power scheduling mode may be exited.
The third preset time and the fourth preset time can be set according to actual communication requirements, the third preset time can be selected to be 3 times, and the fourth preset time can be selected to be 3 times.
Fig. 3 shows a flow chart of a power coordination method according to yet another embodiment of the invention.
As shown in fig. 3, the flow of the power coordination method according to still another embodiment of the present invention includes:
In order to obtain the communication information of the user equipment, a user equipment monitoring instruction can be sent to the base station in the appointed cluster, so that the base station can measure the communication information of the user equipment in a cell supported by the base station according to the user equipment monitoring instruction, and then the measured communication information of the user equipment is sent to the power coordination equipment.
The power coordination equipment can calculate the actual load capacity of each cell according to the communication information of the user equipment in each cell, and further can obtain the matched downlink transmitting power according to the actual load capacity of each cell.
Finally, the cell power scheduling information is sent to the base station, and the base station configures downlink transmission power for each cell supported by the base station according to the actual downlink transmission power required by each cell under the base station indicated in the cell power scheduling information, that is, the power coordination device performs power repartitioning, and the base station is the main body that allocates different powers for each cell according to the repartitioning result.
Through the technical scheme, the downlink transmitting power of each cell can be reasonably adjusted and redistributed in the time domain aiming at the downlink channel according to the actual communication requirement of the user equipment in each cell, so that the actual communication requirement can be adapted to the maximum extent, the interference among the cells is reduced, the channel quality and the network performance are improved, and the user internet experience is improved.
