Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
Fig. 1 is a schematic flow diagram of a base station energy saving method according to an embodiment of the present invention, where an execution main body of the method may be a base station control system, and more specifically, may be a control host used as the base station control system, as shown in fig. 1, the base station energy saving method includes:
step 101: detecting communication traffic of a base station;
specifically, the base station control system detects a real-time Resource occupation situation of a Physical Resource Block (PRB).
The physical resource block is a minimum unit for scheduling resources corresponding to a user in a communication system, and for Time Division-Long Term Evolution (TD-LTE) and Frequency Division duplex (FDD-LTE) of a fourth generation (4G) mobile communication technology, the physical resource block corresponds to 12 continuous subcarriers (subcarrier width 15KHZ) in a Frequency domain and a resource of one slot (half a subframe, 0.5ms) in a Time domain;
a communication service may occupy one or several physical resource blocks.
Here, the communication service may be a voice service or a data service;
for example, a voice service, that is, a user makes a call through a mobile terminal to perform a voice call, generally occupies one physical resource block, and if the service is a data service, it may occupy multiple physical resource blocks;
the communication traffic of the base station can be clearly known by detecting the real-time resource occupation condition of the physical resource block.
Step 102: determining a communication time period to be allocated according to the communication traffic, and allocating the communication traffic to the communication time period according to the communication time period to be allocated;
specifically, when the communication traffic is smaller than the set traffic threshold, the communication time period to be allocated is the communication time period in which the control data is located;
otherwise, the base station control system determines the number of the communication time periods to be allocated according to the communication traffic and the energy-saving allocation amount of the set communication time periods.
In the uplink or downlink channel of the base station, in order to accommodate more services, the time is subdivided into a plurality of communication time periods, each communication time period can accommodate different services, or one service, or one part of one service, so that the whole channel can accommodate more services;
for TD-LTE and FDD-LTE of 4G mobile communication technology, the communication time period is one of the time domains, and each communication time period is arranged in time sequence.
Further, the unit of the communication time period is one symbol, the symbol is one time unit, and the relationship between the symbol and the subframe and the time slot is as follows:
1 subframe is 1 ms;
1 subframe 2 slot 14 symbol.
In the communication time interval, besides the service data of the communication service, there is also control data for controlling the communication service, according to the communication protocol, the control data is distributed on the specific communication time interval in the time domain, that is, the communication time interval of the control data, and the communication time interval of the control data, the power amplifier can not be closed, and the communication time interval of the control data, besides the idle frequency domain capable of containing the control data, also can contain the service data;
therefore, when the base station control system detects that the communication traffic is smaller than the set traffic threshold, the communication traffic can be allocated to the communication time period in which the control data is positioned, namely, the symbol in which the subframe control symbol is positioned, so that the power amplifier can be closed in other communication time periods, and the energy consumption is reduced;
the setting of the traffic threshold is determined according to the energy-saving allocation amount of the communication time period, namely the number of the communication time periods in which the control data is positioned is multiplied by the energy-saving allocation amount to be the numerical value of the traffic threshold.
The energy-saving allocation amount of the communication time period is an allocation amount of the lowest energy consumption, and if the energy-saving allocation amount exceeds the allocation amount, the energy consumption increased by the power amplifier is larger than the energy consumption increased by the power amplifier corresponding to a newly opened communication time period.
And if the base station control system detects that the communication traffic is greater than or equal to the set traffic threshold, determining the number of the communication time periods to be distributed according to the communication traffic.
Specifically, the number of the communication time periods to be allocated is determined according to the energy-saving allocation amount and the communication traffic of the communication time periods, that is, the communication traffic is divided by the energy-saving allocation amount of the communication time periods to determine the number of the communication time periods to be allocated;
after determining the number of the communication time periods to be allocated, the base station control system allocates the communication traffic to the communication time periods, specifically, the communication traffic may be equally allocated to the communication time periods;
when the determined number of the communication time periods to be allocated comprises the communication time period in which the control data is positioned, the communication time period in which the control data is positioned and the determined other communication time periods are uniformly and evenly allocated, and the actual communication traffic amount allocated to each communication time period is equal to the energy-saving allocation amount in value, so that the energy consumption of the whole base station can be reduced to the greatest extent.
Step 103: and according to the communication traffic allocated to the communication time period, the power amplifier is switched on or off in the communication time period.
Specifically, the base station control system turns on the power amplifier in the communication period allocated to the communication service, and turns off the power amplifier in the communication period not allocated to the communication service.
The power amplifier can be turned on or off in a short time corresponding to the communication time period to match the communication traffic of the corresponding communication time period, thereby achieving the effect of energy saving.
Further, the time unit of the communication time period is a symbol, so that the power amplifier can be turned on and off at a symbol level.
Turning on or off the power amplifier is performed according to whether or not the communication traffic is allocated to the communication period, the power amplifier is turned on in the communication period to which the communication traffic is allocated, and the power amplifier is turned off in the communication period to which the communication traffic is not allocated;
further, for the power amplifier that is turned on, in order to save more energy, the drain voltage value of the power amplifier may be adjusted according to the communication traffic allocated to the corresponding communication time period.
Therefore, the power amplifier is turned off in part of the communication time period, and the drain voltage value of the power amplifier can be adjusted when the power amplifier is turned on, so that the energy consumption of the power amplifier is further reduced.
The relation between the drain voltage value and the communication traffic is established according to the characteristics of the power amplifier and the energy consumption condition, and has a certain corresponding relation.
For clarity of description, the relationship between the drain voltage value and the traffic volume is illustrated, and generally, the traffic volume corresponds to different voltage values at different load gears, and the higher the traffic volume, the higher the voltage value.
For example: under the service volume of 20-40%, the corresponding voltage value is 18V; 40% -60% of the traffic corresponds to 24V, and 80% -100% of the traffic corresponds to 32V; in addition, it should be noted that if the traffic is high, the corresponding voltage is low, which may greatly affect the service performance; but the traffic is low, the voltage is high, the performance is not affected, and only energy is wasted.
By way of example only, the relationship between the specific drain voltage value and the traffic volume may be determined by multiple tests according to specific products, such as the type of the base station, the type of the signal, and the like, and may be further improved in use after the determination.
It should be noted that, in addition to the high traffic and low voltage conditions, the frequent adjustment of the drain voltage value may also cause a risk of poor traffic performance, because the time unit of the communication time period of the DTX technique is one symbol, and the time unit of the drain voltage adjustment is one minute, which is very different. In order to ensure the service performance, the communication traffic of the base station is detected, and the maximum traffic in a longer time unit, such as one minute or more, is detected, and a corresponding voltage value is set.
Therefore, in order to save energy, it is necessary to allocate the traffic to the communication time slot evenly, and to make the detected maximum traffic lower as much as possible, so that the voltage value is lower, that is, the traffic is allocated to the communication time slot, and the most preferable method is the average allocation.
Further, when the communication traffic is zero, directly turning on the power amplifier in the communication time period of the control data, adjusting the drain voltage value of the turned-on power amplifier, and turning off the power amplifier in the rest communication time periods;
according to the condition that the communication traffic is zero, a simple flow is set, other steps are not carried out, the power amplifier is directly started in the communication time period of the control data, and the power amplifier is stopped in the rest communication time periods.
Here, the base station control system adjusts the drain voltage value of the power amplifier only according to the data amount of the control data, and the adjusted drain voltage value is very low since there is no communication traffic, so that the power consumption of the power amplifier is very low.
Further, the flow of the method can be divided into the following three types according to the communication traffic, specifically see fig. 2 to 4:
fig. 2 is a detailed flowchart of a base station energy saving method according to an embodiment of the present invention, which is a detailed flowchart illustrating a specific application scenario in which a base station has no user access, and the flowchart includes:
step 201: starting an energy-saving mode, and starting an energy-saving control device in a base station control system;
step 202: the PRB is detected in real time, the real-time resource occupation condition of the PRB is detected through a base station control system, the communication traffic of the base station can be clearly known, and the application scene is that the base station has no user access, so the detected communication traffic is zero;
step 203: starting a power amplifier in a communication time period in which the control data is positioned, and closing the power amplifier in a communication time period in which the control data is not positioned;
because the communication traffic of the application scenario is zero, that is, only the control data is distributed in a specific communication time period, and the power amplifier cannot be turned off in the communication time period in which the control data is located;
therefore, the power amplifier is turned on in the communication time period where the control data is located, and the other power amplifiers are turned off in the communication time period where the control data is absent;
step 204: after the power amplifier is started, adjusting the drain voltage value of the power amplifier according to the data volume of the control data of the current communication time period;
in order to further reduce the power consumption, the drain voltage value of the power amplifier is adjusted according to the working load condition of the power amplifier; the lower the drain voltage value is, the lower the power amplifier energy consumption is;
therefore, the power amplifier is turned off in part of the communication time period, and the drain voltage value of the power amplifier can be adjusted when the power amplifier is turned on, so that the energy consumption of the power amplifier is further reduced;
the relation between the drain voltage value and the communication traffic is established according to the characteristics of the power amplifier and the energy consumption condition, and has a certain corresponding relation.
Fig. 3 is a detailed flowchart of a base station energy saving method according to an embodiment of the present invention, where a specific application scenario is that a base station has a small number of users to access, that is, a communication traffic of the base station is smaller than a set traffic threshold, and the flowchart includes:
step 301: starting an energy-saving mode, and starting an energy-saving control device in a base station control system;
step 302: PRB is detected in real time, and the communication traffic of the base station can be clearly known by detecting the real-time resource occupation condition of the PRB through a base station control system;
step 303: evenly distributing the communication traffic to communication time units in which the control data are positioned;
because the communication traffic is less than the set traffic threshold, the communication time period to be allocated is the communication time period in which the control data is located;
these communication traffic volumes can be equally allocated to the communication time period in which the control data is located, i.e., the symbol in which the subframe control symbol is located;
step 304: starting a power amplifier in a communication time unit where the control data is positioned, and stopping the power amplifier in other communication time units;
turning on or off the power amplifier is performed according to whether or not the communication traffic is allocated to the communication period, the power amplifier is turned on in the communication period to which the communication traffic is allocated, and the power amplifier is turned off in the communication period to which the communication traffic is not allocated;
because the application scenario is that a base station has a small number of users to access, communication traffic is distributed in a communication time period of the control data, a power amplifier is started in a communication time unit of the control data, and the power amplifier is closed in other communication time units.
Step 305: after the power amplifier is started, adjusting the drain voltage value of the power amplifier according to the communication traffic of the current communication time period;
for the power amplifier which is turned on, in order to save more energy, the drain voltage value of the power amplifier can be adjusted according to the communication traffic which is distributed to the corresponding communication time period; the lower the drain voltage value is, the lower the power amplifier energy consumption is;
therefore, the power amplifier is turned off in part of the communication time period, and the drain voltage value of the power amplifier can be adjusted when the power amplifier is turned on, so that the energy consumption of the power amplifier is further reduced;
the relation between the drain voltage value and the communication traffic is established according to the characteristics of the power amplifier and the energy consumption condition, and has a certain corresponding relation.
Fig. 4 is a detailed flowchart of a base station energy saving method according to an embodiment of the present invention, where a specific application scenario is that a base station has a large number of users to access or runs at full load, that is, a communication traffic of the base station is greater than or equal to a set traffic threshold, and the flowchart includes:
step 401: starting an energy-saving mode, and starting an energy-saving control device in a base station control system;
step 402: PRB is detected in real time, and the communication traffic of the base station can be clearly known by detecting the real-time resource occupation condition of the PRB through a base station control system;
step 403: determining a communication time period to be allocated;
because the application scenario is that a base station has a large number of users to access or runs at full load, when the base station control system detects that the communication traffic is greater than the set traffic threshold, the number of communication time periods to be allocated needs to be determined according to the communication traffic;
step 404: evenly allocating communication traffic to the communication time periods;
after the number of the communication time periods to be allocated is determined, the communication traffic is allocated to the communication time periods evenly, so that the energy consumption of the whole base station can be reduced to the maximum extent;
step 405: turning on or off the power amplifier in each communication time period;
turning on or off the power amplifier is performed according to whether or not the communication traffic is allocated to the communication period, the power amplifier is turned on in the communication period to which the communication traffic is allocated, and the power amplifier is turned off in the communication period to which the communication traffic is not allocated;
step 406: after the power amplifier is started, adjusting the drain voltage value of the power amplifier according to the communication traffic of the current communication time period;
for the power amplifier which is turned on, in order to save more energy, the drain voltage value of the power amplifier can be adjusted according to the communication traffic which is distributed to the corresponding communication time period;
therefore, the power amplifier is turned off in part of the communication time period, and the drain voltage value of the power amplifier can be adjusted when the power amplifier is turned on, so that the energy consumption of the power amplifier is further reduced;
the relation between the drain voltage value and the communication traffic is established according to the characteristics of the power amplifier and the energy consumption condition, and has a certain corresponding relation.
The three working flows depend on communication traffic, namely determined after the base station control system detects the real-time resource occupation condition of the PRB, the three working flows are flexibly and quickly switched, and the energy consumption of the base station is greatly reduced.
Fig. 5 is a schematic diagram of an energy saving device of a second base station according to an embodiment of the present invention, and as shown in fig. 5, the energy saving device of the base station includes: a detection module 51, an assignment module 52 and an adjustment module 53; wherein the content of the first and second substances,
the detecting module 51 is configured to detect a communication traffic of a base station;
the allocating module 52 is configured to determine a communication time period to be allocated according to the communication traffic, and allocate the communication traffic to the communication time period according to the communication time period to be allocated;
the adjusting module 53 is configured to turn on or turn off the power amplifier in the communication time period according to the communication traffic allocated to the communication time period.
For clarity of description, the following will respectively describe each module in detail:
the detecting module 51 is configured to detect a communication traffic of a base station;
specifically, the detecting module 51 detects a real-time resource occupation condition of the physical resource block.
The physical resource block is the minimum unit for scheduling resources corresponding to users in a communication system, and for TD-LTE and FDD-LTE of 4G mobile communication technology, the physical resource block corresponds to 12 continuous subcarriers (subcarrier width 15KHZ) in a frequency domain and resources of one time slot (half subframe, 0.5ms) in a time domain;
a communication service may occupy one or several physical resource blocks.
Here, the communication service may be a voice service or a data service;
for example, a voice service, that is, a user makes a call through a mobile terminal to perform a voice call, generally occupies one physical resource block, and if the service is a data service, it may occupy multiple physical resource blocks;
the communication traffic of the base station can be clearly known by detecting the real-time resource occupation condition of the physical resource block.
The allocating module 52 is configured to determine a communication time period to be allocated according to the communication traffic, and allocate the communication traffic to the communication time period according to the communication time period to be allocated;
specifically, when the communication traffic is smaller than the set traffic threshold, the communication time period to be allocated is the communication time period in which the control data is located;
otherwise, the allocating module 52 determines the number of the communication time periods to be allocated according to the communication traffic and the energy-saving allocation amount of the set communication time period.
In the uplink or downlink channel of the base station, in order to accommodate more services, the time is subdivided into a plurality of communication time periods, each communication time period can accommodate different services, or one service, or one part of one service, so that the whole channel can accommodate more services;
for TD-LTE and FDD-LTE of 4G mobile communication technology, the communication time period is one of the time domains, and each communication time period is arranged in time sequence.
Further, the unit of the communication time period is one symbol, the symbol is one time unit, and the relationship between the symbol and the subframe and the time slot is as follows:
1 subframe is 1 ms;
1 subframe 2 slot 14 symbol.
In the communication time interval, besides the service data of the communication service, there is also control data for controlling the communication service, according to the communication protocol, the control data is distributed on the specific communication time interval in the time domain, that is, the communication time interval of the control data, and the communication time interval of the control data, the power amplifier can not be closed, and the communication time interval of the control data, besides the idle frequency domain capable of containing the control data, also can contain the service data;
therefore, when the detection module 51 detects that the communication traffic is smaller than the set traffic threshold, the communication traffic can be allocated to the communication time period in which the control data is located, that is, the symbol in which the subframe control symbol is located, so that the power amplifier can be turned off in other communication time periods, thereby reducing energy consumption;
the setting of the traffic threshold is determined according to the energy-saving allocation amount of the communication time period, namely the number of the communication time periods in which the control data is positioned is multiplied by the energy-saving allocation amount to be the numerical value of the traffic threshold.
The energy-saving allocation amount of the communication time period is an allocation amount of the lowest energy consumption, and if the energy-saving allocation amount exceeds the allocation amount, the energy consumption increased by the power amplifier is larger than the energy consumption increased by the power amplifier corresponding to a newly opened communication time period.
If the detection module 51 detects that the communication traffic is greater than or equal to the set traffic threshold, the number of communication time periods to be allocated is determined according to the communication traffic.
Specifically, the number of the communication time periods to be allocated is determined according to the energy-saving allocation amount and the communication traffic of the communication time periods, that is, the communication traffic is divided by the energy-saving allocation amount of the communication time periods to determine the number of the communication time periods to be allocated;
after determining the number of the communication time periods to be allocated, the allocating module 52 allocates the communication traffic to the communication time periods, specifically, allocates the communication traffic to the communication time periods on an average basis;
when the determined number of the communication time periods to be allocated comprises the communication time period in which the control data is positioned, the communication time period in which the control data is positioned and the determined other communication time periods are uniformly and evenly allocated, and the actual communication traffic amount allocated to each communication time period is equal to the energy-saving allocation amount in value, so that the energy consumption of the whole base station can be reduced to the greatest extent.
The adjusting module 53 is configured to turn on or turn off the power amplifier in the communication time period according to the communication traffic allocated to the communication time period.
Specifically, the adjusting module 53 turns on the power amplifier in the communication period allocated to the communication traffic, and turns off the power amplifier in the communication period not allocated to the communication traffic.
The power amplifier can be turned on or off in a short time corresponding to the communication time period to match the communication traffic of the corresponding communication time period, thereby achieving the effect of energy saving.
Further, the time unit of the communication time period is a symbol, so that the power amplifier can be turned on and off at a symbol level.
Turning on or turning off the power amplifier is performed according to whether or not the communication traffic is allocated to the communication time period, the power amplifier is turned on in the communication time period in which the communication traffic is allocated, and the power amplifier is turned off in the communication time period in which the communication traffic is not allocated;
further, for the power amplifier that is turned on, in order to save more energy, the adjusting module 53 may be further configured to adjust the drain voltage value of the power amplifier according to the communication traffic allocated to the corresponding communication time period.
Therefore, the power amplifier is turned off in part of the communication time period, and the drain voltage value of the power amplifier can be adjusted when the power amplifier is turned on, so that the energy consumption of the power amplifier is further reduced.
The relation between the drain voltage value and the communication traffic is established according to the characteristics of the power amplifier and the energy consumption condition, and has a certain corresponding relation.
For clarity of description, the relationship between the drain voltage value and the traffic volume is illustrated, and generally, the traffic volume corresponds to different voltage values at different load gears, and the higher the traffic volume, the higher the voltage value.
For example: under the service volume of 20-40%, the corresponding voltage value is 18V; 40% -60% of the traffic corresponds to 24V, and 80% -100% of the traffic corresponds to 32V; in addition, it should be noted that if the traffic is high, the corresponding voltage is low, which may greatly affect the service performance; but the traffic is low, the voltage is high, the performance is not affected, and only energy is wasted.
By way of example only, the relationship between the specific drain voltage value and the traffic volume may be determined by multiple tests according to specific products, such as the type of the base station, the type of the signal, and the like, and may be further improved in use after the determination.
It should be noted that, in addition to the high traffic and low voltage conditions, the frequent adjustment of the drain voltage value may also cause a risk of poor traffic performance, because the time unit of the communication time period of the DTX technique is one symbol, and the time unit of the drain voltage adjustment is one minute, which is very different. In order to ensure the service performance, the communication traffic of the base station is detected, and the maximum traffic in a longer time unit, such as one minute or more, is detected, and a corresponding voltage value is set.
Therefore, in order to save energy, it is necessary to allocate the traffic to the communication time slot evenly, and to make the detected maximum traffic lower as much as possible, so that the voltage value is lower, that is, the traffic is allocated to the communication time slot, and the most preferable method is the average allocation.
Further, when the communication traffic is zero, directly turning on the power amplifier in the communication time period of the control data, adjusting the drain voltage value of the turned-on power amplifier, and turning off the power amplifier in the rest communication time periods;
according to the condition that the communication traffic is zero, a simple flow is set, other steps are not carried out, the power amplifier is directly started in the communication time period of the control data, and the power amplifier is stopped in the rest communication time periods.
Here, the adjusting module 53 adjusts the drain voltage value of the power amplifier only according to the data amount of the control data, and since there is no communication traffic, the adjusted drain voltage value is very low, and thus, the power consumption of the power amplifier is very low.
In practical applications, the detecting module 51, the allocating module 52 and the adjusting module 53 may be implemented by a Central Processing Unit (CPU), a microprocessor unit (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like located in the base station.
