Description
Technical Field
The present invention relates to the field of communications network technologies, and in particular, to a power allocation method and apparatus.
background
In the deployment of a new generation mobile communication network, a broadband multimode base station is introduced in order to realize multi-mode services. The mode of transforming the traditional single-mode base station into the broadband multimode base station is as follows: first, baseband boards of different systems, for example, baseband boards of Global System for Mobile Communication (GSM) and Wideband Code Division Multiple Access (WCDMA) types, are inserted into the same baseband frame of a base station to form a Wideband multimode base station, and then fixed slots are allocated for different systems, for example, slots 1 to 5 are allocated for the WCDMA System, and slots 6 to 7 are allocated for the GSM System. After the single-mode base station is modified into the wideband multi-mode base station, the wideband multi-mode base station sets the power corresponding to each system to support the service of each system, for example, the total power of the wideband multi-mode base station is 200W, where the power corresponding to the GSM system is 100W, and the power corresponding to the WCDMA system is 100W.
Generally, the power of the wideband multimode base station is much larger than that of the single mode base station, and therefore, during the operation of the wideband multimode base station, the power consumption is too large, which causes the wideband multimode base station to generate more heat, and the power of the wideband multimode base station is rapidly reduced due to too large heat loss.
At present, when a broadband multimode base station normally works, power with a fixed size is respectively allocated to each system, and then if the total power of the broadband multimode base station is greatly reduced, the actual power corresponding to each system may not reach the power allocated to the broadband multimode base station by the broadband multimode base station.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In order to solve the problem that the total power of a broadband multimode base station is greatly reduced, which causes the deterioration of the communication quality of a terminal under each system, an embodiment of the present invention provides a power allocation method, as shown in fig. 1, the method includes:
step 101, the base station respectively obtains the traffic corresponding to each system and the number of terminals corresponding to each system in the target cell.
It can be understood that the broadband multimode base station may manage a plurality of cells, and the embodiment of the present invention only takes the example that the broadband multimode base station manages one cell to illustrate the method of power allocation. For example, the cell a managed by the wideband multimode base station supports four systems, namely GSM, WCDMA, Frequency Division duplex Long Term Evolution (FDD-LTE), and Time Division duplex Long Term Evolution (TDD-LTE).
Step 102, the base station calculates the traffic proportion corresponding to each system in the target cell respectively.
And the traffic proportion is the proportion of the traffic corresponding to each system in the target cell in the total traffic of the target cell.
After the calculation, the traffic proportions corresponding to the 4 systems in the cell a are assumed to be 0.05, 0.45, 0.25, and 0.25, that is, in the cell a, the traffic proportion corresponding to the terminal using the GSM system is 0.05, the traffic proportion corresponding to the terminal using the WCDMA system is 0.45, the traffic proportion corresponding to the terminal using the FDD-LTE system is 0.25, and the traffic proportion corresponding to the terminal using the TDD-LTE system is 0.25.
Step 103, the base station calculates the terminal ratio example corresponding to each system in the target cell.
And the ratio of the number of the terminals is the ratio of the number of the terminals corresponding to each system in the target cell to the total number of the terminals in the target cell.
For example, in cell a, the ratio of the number of terminals corresponding to each of the 4 systems is calculated to be 0.04, 0.46, 0.2, and 0.3.
and step 104, if the base station determines that the total power of the target cell is smaller than the power threshold, redistributing the power corresponding to each system according to the traffic proportion corresponding to each system in the target cell and the terminal ratio corresponding to each system.
it should be noted that the communication quality of the terminal in the target cell may be significantly degraded only when the total power of the target cell is less than the power threshold. For example, the total power of the target cell is 200W, when the total power of the target cell is reduced to 160W, the terminal in each standard can still perform normal communication, and when the total power of the target cell is less than 150W, it is likely that the terminal in some standards cannot perform normal communication, so 150W may be used as the power threshold. It can be understood that, in the embodiment of the present invention, when the communication quality of the terminal does not significantly decrease, the power corresponding to each system in the target cell is not adjusted, and the power corresponding to each system is reallocated only when the total power of the target cell is less than the power threshold, so as to optimize the communication quality of the terminal in each system.
the power distribution method provided by the embodiment of the invention obtains and calculates the traffic proportion and the terminal number proportion corresponding to each system in the cell, when the power of the multimode broadband base station is reduced, compared with the prior art that the communication quality of the terminal under each standard cannot be optimized, in the embodiment of the invention, the power corresponding to each system can be redistributed in a self-adaptive manner according to the traffic proportion and the terminal number proportion corresponding to each system, so that the broadband multimode base station can redistribute the power corresponding to each system more evenly, thereby avoiding distributing larger power to the system with small power requirement, the power waste caused by the method, and simultaneously, the method avoids distributing smaller power to the system with large power demand, therefore, the communication quality of the terminal under the system with high power requirement is ensured, and the communication quality of the terminal under each system can be optimized.
It should be noted that, when the total power of the target cell is smaller than the power threshold, the power corresponding to each system needs to be reallocated, and based on this, as shown in fig. 2, in another implementation manner provided in the embodiment of the present invention, step 104, reallocating the power corresponding to each system according to the traffic proportion corresponding to each system in the target cell and the terminal ratio proportion corresponding to each system respectively includes:
step 201, the base station determines that the traffic proportion in the target cell is the maximum, and the mode that the terminal number proportion is greater than or equal to the terminal number proportion threshold is the dominant mode; and determining that the traffic proportion is smaller than a traffic proportion threshold value, the mode in which the terminal number proportion is smaller than the terminal number proportion threshold value is a disadvantaged mode, and the modes except the dominant mode and the disadvantaged mode are intermediate modes.
Assuming that the preset traffic proportion threshold is 0.4 and the terminal ratio proportion threshold is 0.05, in combination with the above example, in the target cell, the traffic proportion corresponding to WCDMA is the largest, and the number of terminals communicating through WCDMA is 0.46> the terminal ratio proportion threshold is 0.05, then WCDMA is taken as the dominant mode.
it should be noted that, in the embodiment of the present invention, in order to avoid that an illegal terminal sends a large amount of data in a traffic attack manner, occupies a large amount of resources such as bandwidth of a communication network, and causes a bad influence on the communication network, when a traffic proportion corresponding to the system a is the largest, a terminal ratio example that the system a is used to send data needs to be determined, if the terminal ratio example that the system a is used to send data is smaller than a terminal ratio example threshold, it is indicated that a terminal that the system a is used to send data is an illegal terminal, and correspondingly, the system a is an illegal system.
it can be understood that, when an illegal system exists in the target cell, the traffic proportions corresponding to each system can be sorted according to the sequence of the traffic proportions from large to small, and then the system with the largest traffic proportion after the illegal system in the traffic proportion sorting is selected as the dominant system. For example, there are the following 5 systems, and the 5 systems are arranged in order of the traffic proportion from large to small: system A, system B, system C, system D, system E. If the system A is an illegal system, judging whether the terminal ratio number corresponding to the system B is smaller than a terminal ratio number threshold, if the terminal ratio number corresponding to the system B is smaller than the terminal ratio number threshold, the system B is also used as the illegal system, further judging whether the terminal ratio number of the system C is smaller than the terminal ratio number threshold, and if the terminal ratio number corresponding to the system C is larger than or equal to the terminal ratio threshold, the system C is used as a dominant system.
As shown in the above example, if the traffic proportion 0.05 corresponding to GSM is less than the traffic proportion threshold 0.4, and the terminal ratio case 0.04 corresponding to GSM is less than the terminal ratio case threshold 0.05, then GSM is used as the disadvantaged system
it can be understood that, after determining the dominant and the subordinate, FDD-LTE and TDD-LTE other than the dominant and the subordinate are used as intermediate systems.
Step 202, the base station calculates the original configuration power corresponding to the dominant mode and the pre-configuration power corresponding to the dominant mode.
the original configuration power is the configuration power corresponding to each system before the critical moment, the pre-configuration power is the configuration power corresponding to each system after the critical moment, and the critical moment is the moment when the total power of the target cell is determined to be smaller than the power threshold.
The original configuration power corresponding to the dominant mode is the pre-configuration power corresponding to the dominant mode, Pbef is the sum of the original configuration power corresponding to each mode in the target cell, and servi is the traffic corresponding to the mode i and the sum of the traffic corresponding to each mode in the target cell.
First, for example, in conjunction with the critical time in the embodiment of the present invention, when the wideband multimode base station is operating stably and normally, the total power of the target cell is maintained at 200W, and the terminals in the target cell can all communicate normally. Then, at the time a, the total power of the target cell suddenly drops to 100W, and at this time, the broadband multimode base station detects that the total power (100W) of the target cell is smaller than the power threshold (150W), and then the broadband multimode base station regards the time a as a critical time.
It should be noted that before calculating the reconfiguration power corresponding to the dominant system, in order to avoid using the terminal of the illegal system to maliciously attack the communication network, the power corresponding to the illegal system needs to be adjusted to 0.
Combining the above example of steps, assuming that the power threshold is 150W, if the wideband multimode base station is in a normal and stable working state, the total power of the target cell is maintained at 200W, and after the original configured power corresponding to the dominant WCDMA is, the total power of the target cell is suddenly decreased to 100W, the time when the total power of the target cell is suddenly decreased to 100W is taken as a critical time, and at the critical time, the total power of the target cell is 100W, the pre-configured power corresponding to the dominant WCDMA is taken as a critical time
Step 203, if the base station determines that the original configuration power corresponding to the dominant mode is smaller than the total power of the target cell at the critical moment, determining the reconfiguration power corresponding to the dominant mode according to the original configuration power corresponding to the dominant mode and the preconfigured power corresponding to the dominant mode. The reconfiguration power corresponding to the dominant system is Psup, i is Pbef, i is k1+ Paft, i is k2, k1 and k2 are power adjustment coefficients, and k1+ k2 is 1.
With reference to the example in step 202, before the critical time, the original configured power required to be allocated to the dominant mode according to the traffic proportion is 90W to ensure the communication quality of the terminal using the dominant mode, and after the critical time, the preconfigured power required to be allocated to the dominant mode according to the traffic proportion is 45W. In order to allocate more reasonable reconfiguration power for the dominant standard in the target cell, in the embodiment of the present invention, power adjustment parameters k1 and k2 are provided. By adjusting k1 and k2, the reconfigured power corresponding to the dominant standard can be infinitely close to the original configured power corresponding to the dominant standard, or the reconfigured power corresponding to the dominant standard can be infinitely close to the pre-allocated power corresponding to the dominant standard, or the power value corresponding to the dominant standard can be adjusted to any power value between the original configured power and the pre-allocated power.
In combination with the above example, assuming that k1 is 0.8 and k2 is 0.2, before the critical time, the original configured power 90W corresponding to the WCDMA system < the total power 100W of the target cell at the critical time. Therefore, the reconfiguration power corresponding to the dominant WCDMA system is determined to be Psup, i is 90W 0.8+45W 0.2 is 81W.
Step 204, the base station adjusts the reconfiguration power corresponding to the disadvantaged system to 0.
As an achievable way, after the critical time, the reconfiguration power corresponding to the disadvantaged system may be adjusted to 0, so as to allocate the power corresponding to the disadvantaged system to another system with a larger traffic volume for use, thereby improving the communication quality of the terminal in the system with a larger traffic volume ratio.
step 205, the base station calculates the remaining power, where the remaining power is the difference between the total power of the target cell at the critical moment and the reconfiguration power corresponding to the dominant mode.
Combining the above examples, the remaining power is 100W-81W-19W.
And step 206, the base station respectively adjusts the reconfiguration power corresponding to each intermediate system according to the traffic proportion and the residual power.
The reconfiguration power corresponding to each intermediate system is Pleft as the residual power, servj is the traffic corresponding to the intermediate system j, and is the sum of the traffic corresponding to each intermediate system in the target cell.
By combining the above example, for the intermediate systems TD-LTE and FDD-LTE, the reconfiguration power corresponding to the intermediate system TD-LTE is obtained as
the reconfiguration power corresponding to the intermediate FDD-LTE is
the method for power distribution provided in the embodiment of the present invention first determines the type of each system according to the traffic proportion and the terminal ratio proportion corresponding to each system in a target cell, then calculates the original configuration power Pbef, i corresponding to the dominant system and the preconfigured power Paft, i corresponding to the dominant system, if the original configuration power corresponding to the dominant system is smaller than the preconfigured power corresponding to the dominant system, the power distributed to the dominant system is Psup, i is Pbef, i is k1+ Paft, i is k2, so as to ensure that sufficient power is distributed to the dominant system, and adjusts the power corresponding to the dominant system to 0, so that the power corresponding to the dominant system is distributed to other systems with large traffic proportion, and finally calculates the remaining power, and distributes the remaining power to the intermediate system according to the traffic proportion. Therefore, in the embodiment of the present invention, after the types of each system are determined according to the traffic proportion and the terminal ratio, more power can be allocated to the system with the larger traffic proportion, and less power can be allocated to the system with the smaller traffic, so that the power allocated to each system is more balanced, and the communication quality of the terminal in each system is optimized.
it should be noted that, when the original configuration power corresponding to the dominant mode is greater than the total power of the target cell at the critical time, it is indicated that the broadband multimode base station cannot allocate a sufficiently large power to the dominant mode, and at this time, power should be allocated to the dominant mode and other modes except the dominant mode according to a traffic proportion, based on this, in another implementation manner provided in the embodiment of the present invention, as shown in fig. 3, after step 202, calculating the original configuration power corresponding to the dominant mode and the preconfigured power corresponding to the dominant mode, step 301 may also be performed.
step 301, if the original configuration power corresponding to the dominant standard is greater than the total power of the target cell at the critical moment, the base station readjusts the power corresponding to each standard in the target cell according to the traffic proportion, where the power corresponding to each standard is the total power of the target cell at the critical moment, and servk is the traffic corresponding to the standard k and is the traffic proportion corresponding to the standard k.
assuming that the total power of the wideband multimode base station is maintained at 200W before the critical time, and the traffic proportions corresponding to the four systems of GSM, WCDMA, TDD-LTE and FDD-LTE in the cell a are 0.05, 0.6, 0.2 and 0.15, respectively, then the power of the wideband multimode base station suddenly decreases after the original configuration power corresponding to the dominant system WCDMA is, resulting in a total power of the target cell at the critical time of 100W. Because the original configuration power (120W) corresponding to the dominant standard is greater than the total power of the target cell at the critical moment by 100W, the power of each standard is obtained according to the traffic proportion as follows:
The power corresponding to the dominant standard WCDMA is the power corresponding to the inferior standard GSM is the power corresponding to the intermediate standard TDD-LTE is the power corresponding to the intermediate standard FDD-LTE
According to the power distribution method provided by the embodiment of the invention, when the original configuration power corresponding to the dominant standard is larger than the total power of the target cell at the critical moment, the power corresponding to each standard is readjusted according to the traffic proportion, so that each standard obtains the power required by each standard, and therefore, the communication quality of the terminal under each standard can be optimized.
It should be noted that, in order to make the power adjustment more accurate, the traffic proportion and the terminal number proportion corresponding to each system should be re-determined according to the communication status of the terminal under each system, and the power corresponding to each system should be re-allocated according to the re-determined traffic proportion, based on this, in another implementation manner provided in the embodiment of the present invention, as shown in fig. 4, after the power corresponding to each system is re-allocated in step 104 according to the traffic proportion corresponding to each system in the target cell and the terminal number proportion corresponding to each system, step 401 to step 402 may also be executed.
step 401, in a preset period, the base station re-determines the traffic proportion corresponding to each system and the terminal number proportion corresponding to each system in the target cell.
it should be noted that, for the cell a, before the power adjustment procedure is executed, the traffic volume ratios corresponding to the four systems, i.e., GSM, WCDMA, FDD-LTE, and TDD-LTE, are 0.05, 0.45, 0.25, and 0.25, respectively. After the first power adjustment process, in a preset period, the communication status of the terminal in each system changes, for example, the traffic proportion of the terminal using the WCDMA system for communication increases, and the number of terminals using the WCDMA system for communication also increases, and at this time, the wideband multimode base station needs to re-determine the traffic proportion corresponding to each system and the number of terminals corresponding to each system. For example, the broadband multimode base station determines the traffic volume ratios corresponding to the four systems of GSM, WCDMA, FDD-LTE and TDD-LTE to be 0.05, 0.65, 0.15 and 0.15, respectively, and the terminal number ratios corresponding to the four systems are 0.04, 0.56, 0.1 and 0.3.
Step 402, the base station redistributes the power corresponding to each system according to the traffic proportion corresponding to each system in the redetermined target cell and the terminal ratio proportion corresponding to each system in the redetermined target cell.
It can be understood that, after the traffic proportion corresponding to each system and the terminal proportion corresponding to each system are re-determined, the broadband multimode base station may execute the power allocation procedure corresponding to steps 201 to 206, or execute the power allocation procedure corresponding to step 301, so as to re-allocate the power corresponding to each system, and optimize the communication quality of the terminal in each system.
according to the power distribution method provided by the embodiment of the invention, in a preset period, the broadband multimode base station can re-determine the traffic proportion corresponding to each system and the terminal number proportion corresponding to each system according to the communication condition of the terminal, and then re-distribute the power of each system according to the re-determined traffic proportion corresponding to each system and the terminal number proportion corresponding to each system, so that the accuracy of the power distribution method is ensured.
