It should be understood that the specific embodiments described herein are intended to be illustrative of the application and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing an example of the present application.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The embodiments will be described in detail below with reference to the accompanying drawings.
With the advancement of wireless communication technology, wireless networks have achieved a transition from circuit transmission to packet transmission, and the times of 4G and 5G have been entered from 2G and 3G. Most voice users gradually transit to 4G VOLTE voice from original 2G and 3G voice exchanged by the circuit domain, and then use 5G VONR voice.
The VONR technology, that is, the voice technology carried by 5G, can make the voice on waiting time shorter, and obtain higher quality and more natural voice-video call effect, and the VONR voice is an end-to-end voice scheme constructed on the 5G network under the all-IP condition, and compared with the existing voice call, the voice quality can be improved by about 40%.
Because VONR voice adopts a high resolution coding and decoding technology and a 5G network has no dedicated traffic channel, it cannot be directly applied to downlink closed loop power control. Meanwhile, due to the high quality requirement of voice service on a link, a semi-static scheduling-like mode is adopted in resource allocation, so that the special service channel benefit is obtained by the VONR connection, and the downlink closed-loop power control can be applied.
The VONR technology brings high-quality voice experience and increases interference to other links, so that the downlink transmission power of the links needs to be controlled by an efficient means, however, two methods for power control in the related art include two methods, namely a fixed power allocation method, wherein the fixed power allocation method is used for equally allocating the total transmission power to each RB; the other is a rule dynamic adjustment method, which is to dynamically adjust the downlink power according to the target carrier-to-interference ratio and the actual carrier-to-interference ratio.
The above-mentioned transmitting power determining method does not consider the problem of service degradation caused by the failure of the cell in the current network, so that the transmitting power cannot be accurately controlled.
Specifically, in order to solve the problems in the prior art, embodiments of the present application provide a method, an apparatus, a device, a storage medium, and a program product for determining a transmission power of a voice link. The following first describes a method for determining the transmit power of a voice link provided in an embodiment of the present application.
Fig. 1 is a flow chart of a method for determining a transmit power of a voice link according to an embodiment of the present application. The method comprises the following steps:
S110, acquiring fault information of a first cell, wherein the first cell is a resident cell of the electronic equipment.
In this embodiment, the failure information of the first cell, that is, the failure information in the cell that may affect the link quality, may be relevant information of a feeder line failure in the cell, may be relevant information of a standing wave ratio failure, or may be other failure information that may affect the voice link. When a cell experiences faults, the sensing condition of the VONR user on the VONR voice can be influenced, so that the transmitting power of a voice link needs to be correspondingly improved to ensure the sensing of the VONR user on the VONR voice.
S120, determining the target quality of the voice link according to the distance coefficient from the base station corresponding to the voice link to the electronic equipment and the fault information.
In this embodiment, the target quality is set by the user, and when the link quality is higher than the target quality, the noise floor caused by the voice link can be reduced by reducing the transmitting power of the voice link; when the link quality is lower than the target quality, the perception of the VONR voice by the user can be improved by improving the transmitting power of the voice link.
In this embodiment, the fault information of the cell and the distance from the base station to the electronic device in the cell all affect the target quality. When the cell has fault information, the target quality can be properly improved so as to counteract the influence of the fault on the voice link.
The distance coefficient is determined by the distance from the base station to the electronic device, and in general, the further the electronic device is from the base station, the more unstable the voice link connecting the electronic device and the base station is, and the more susceptible to various types of fading, so that the corresponding distance coefficient can be determined according to the distance between the electronic device and the base station, and the target quality determination process can be incorporated.
S130, determining the transmitting power of the voice link according to the target quality and the link quality of the voice link.
In this embodiment, after determining the target quality of the voice link of the electronic device, the target quality and the current link quality of the voice link may be compared, and the transmit power of the voice link may be determined according to the comparison result. For example, when the link quality is greater than the target quality and the link quality and the target quality differ greatly, the transmit power may be reduced by 3 steps; when the link quality is larger than the target quality and the difference between the link quality and the target quality is smaller, the transmitting power of 1 step length can be reduced; when the link quality is smaller than the target quality and the link quality and the target quality differ greatly, the transmitting power of 3 steps can be increased; when the link quality is less than the target quality and the link quality and the target quality differ less, the transmission power may be increased by 1 step.
In an embodiment, as shown in fig. 2, the voice link includes a power control intelligent module, where the power control intelligent module can measure the current link quality of the voice link, obtain a set target quality, generate a corresponding power control command based on the link quality and the target quality and combine with fault information existing in the cell, and perform closed-loop dynamic adjustment on the downlink transmission power of the voice link.
The transmitting power of the voice link in the next stage is determined by acquiring the fault information of the cell and determining the target quality reached by the expected voice link according to the fault content of the fault information, and then comparing the existing link quality with the target quality.
As an alternative embodiment, in order to ensure accuracy of the target quality, S120 may include:
s210, determining a fault adjustment coefficient corresponding to the fault information;
s220, determining a first sum value of the fault adjustment coefficient and a preset value;
and S230, determining the product of the first sum value, the distance coefficient and the cell parameter setting value as the target quality.
In this embodiment, the fault information includes a fault content and a fault adjustment coefficient, where the fault adjustment coefficient characterizes an adjustment degree of the target quality, and since different fault contents have different influences on the voice link, the fault adjustment coefficients corresponding to the different fault contents are different, and the fault adjustment coefficient of the target quality can be determined according to the fault content.
For example, when the fault content is standing wave ratio fault, the target quality can be improved by 10%, the fault adjustment coefficient corresponding to the fault information is 10%, when the fault content is standing wave ratio exceeding limit, the target quality can be improved by 20%, the fault adjustment coefficient corresponding to the fault information is 20%, and when the fault content is other faults possibly affecting the voice link, the target quality can be improved by 10%, and the fault adjustment coefficient corresponding to the fault information is 10%.
After determining the fault adjustment coefficient corresponding to the fault information, a first sum of the fault adjustment coefficient and a preset value may be determined, and a product of the first sum, the distance coefficient, and the cell parameter setting value may be determined as the target quality. The cell parameter setting value can be set in advance according to the specific conditions of the cell, such as the environment and the azimuth of the cell.
In one embodiment, the target mass is calculated by:
γ tar ＝γ s *(1+h)*d i
wherein i represents the ith electricitySub-device, gamma tar For the target mass gamma s Setting a value d for a cell parameter i In the above embodiment, the preset value is 1, and in other embodiments, the preset value may be other constants.
According to the method and the device, the accuracy of the target quality can be ensured by taking the fault information existing in the cell, the distance of the voice link and the specific condition of the cell as the reference factors of the target quality.
As an alternative embodiment, in order to ensure accuracy of the distance coefficient, before S120, the method may further include:
s310, acquiring the minimum timing advance of the electronic equipment and a first timing advance, wherein the first timing advance is the timing advance of the electronic equipment in the t-1 th period;
s320, determining the distance coefficient according to the first timing advance and the minimum timing advance.
In this embodiment, the timing advance is a command sent by the base station to the electronic device of the user to adjust the uplink transmission power of the electronic device, and in general, the farther the electronic device is from the base station, the larger the corresponding timing advance is, so the distance coefficient of the electronic device can be determined according to the timing advance.
In addition, in this embodiment, the transmit power of the voice link to be determined is adjusted once per period, where the transmit power of the voice link is the transmit power of the voice link in the t-th period, and t is an integer greater than 1.
Due to the performance limitation of the electronic equipment, the electronic equipment has the determined maximum timing advance and the determined minimum timing advance, the minimum timing advance of the electronic equipment can be obtained, the first timing advance of the electronic equipment in the t-1 period is obtained, and then the distance coefficient is determined according to the minimum timing advance and the first timing advance.
The distance coefficient may be determined by: first, the minimum timing advance Ta of the electronic equipment is obtained min And maximum timing advanceTa max And then determining a calculation coefficient of a distance coefficient according to the minimum timing advance and the maximum timing advance, wherein the determination formula of the calculation coefficient is as follows:
v＝(b-a)/(Ta max -Ta min )
wherein v is a calculation coefficient, b and a are constants set in advance, b is greater than a, ta max For maximum timing advance, ta min Is the minimum timing advance.
Based on the constants a and b, a section [ a, b ] can be generated, and the distance coefficient of the electronic equipment can be mapped onto the section to obtain the distance coefficient of the electronic equipment, wherein a specific calculation formula is as follows:
d i ＝a+v*(Ta i -Ta min )
Wherein d i For the distance coefficient from the base station to the ith electronic equipment, a is a constant set in advance, ta min For minimum timing advance, ta i The first timing advance of the t-1 th period is calculated as v.
The distance between the base station of the 5GVONR voice and the electronic equipment is difficult to directly measure, and the embodiment measures the timing advance of the electronic equipment and accurately determines the distance coefficient between the electronic equipment and the base station according to the timing advance.
As an alternative embodiment, in order to accurately and clearly determine the transmit power of the voice link, S130 may include:
s410, determining a plurality of rewards values according to the target quality and a preset rewards function;
s420, determining the link quality corresponding to the maximum rewarding value in the plurality of rewarding values as the first link quality;
s430, determining a first transmitting power according to the first link quality;
s440, determining the first transmitting power as the transmitting power of the voice link under the condition that the first transmitting power is smaller than or equal to the maximum transmitting power of the voice link;
And S450, determining the maximum transmission power as the transmission power of the voice link under the condition that the first transmission power is larger than the maximum transmission power.
In this embodiment, since the transmit power of the voice link is controlled to control the link quality, so that the link quality is closer to the target quality, the transmit power of the network is reduced as much as possible on the basis of ensuring the voice quality, and interference to other voice links in the same base station is reduced. In view of the above, a reward function may be set, where the reward function is a function of link quality, and when different link qualities are input into the reward function, a higher output reward value indicates that the link quality corresponding to the reward value meets the expectations of the user.
For example, if the link quality varies in units of a period and different transmission powers are obtained in the t-1 th period by performing different transmission power control, a plurality of different link qualities in the t-1 th period can be further obtained, and a plurality of bonus values in the t-1 th period can be obtained by inputting the plurality of link qualities into the bonus function, respectively. And determining a maximum reward value among the plurality of reward values, determining the link quality corresponding to the maximum reward value as a first link quality, and determining a first transmission power corresponding to the first link quality.
Since the first transmission power is the transmission power most conforming to the user's expectation in the t-th period, the first transmission power and the maximum transmission power of the voice link can be compared, the first transmission power is determined to be the transmission power of the voice link when the first transmission power is less than or equal to the maximum transmission power of the voice link, and the maximum transmission power is determined to be the transmission power of the voice link when the first transmission power is greater than the maximum transmission power.
According to the method and the device, the degree of link quality matching with the expected degree of the user is quantized by setting the reward function, and the actual transmitting power of the voice link is determined based on the transmitting power corresponding to the link quality which is most consistent with the expected state of the user, so that the transmitting power of the voice link can be accurately and clearly determined.
As an alternative embodiment, in order to ensure the comprehensiveness of the prize value calculation, S410 may include:
s510, at least one power transmitting state of the voice link in the t-1 period is acquired;
s520, at least one power control command of the voice link in the t-1 period is acquired;
s530, executing each power control command in the at least one power control command in each power transmission state in the at least one power transmission state to obtain a plurality of link qualities of the voice link in a t-th period;
S540, determining the rewarding value corresponding to each link quality in the multiple link qualities of the voice link in the t-1 period according to the target quality, the link quality of the voice link in the t-1 period and the rewarding function.
In this embodiment, the voice link may have different power transmission states in different periods, where the power transmission states are states of power variation, and the power transmission states include at least a constant transmission power, an increase in transmission power, and a decrease in transmission power, and the power control intelligent module may detect all the power transmission states in which the voice link may be in.
In addition, under the condition that the voice link is in a certain power transmitting state, the power control intelligent module can send different power control commands to the voice link so as to change the transmitting power of the voice link in different modes, and further obtain different link quality, wherein the power control commands can be used for not adjusting the transmitting power, increasing the transmitting power by any step length or reducing the transmitting power by any step length.
Taking the t-1 th period as an example, in the t-1 th period, the power control intelligent module can collect at least one power transmission state possibly existing in the wireless environment of the voice link, can select at least one power control command possibly executed in the t-1 th period, can select the power transmission state from the at least one power transmission state respectively, can select the power control command from the at least one power control command respectively, and can obtain all possible link qualities of the voice link in the t period by combining the selected power transmission state and the power control command arbitrarily.
The link quality of the t-1 th period and the set target quality can be obtained, and the link quality of the t-1 th period, the target quality and all possible link qualities of the t period are input into a reward function to determine the reward value corresponding to each link quality in the link qualities of the t period.
In this embodiment, a reinforcement learning model may be constructed, and each power emission state and each power control command may be respectively combined by the reinforcement learning model, and the prize value corresponding to each combination may be determined. The reinforcement learning model may determine the prize values for each combination by a greedy algorithm.
In addition, the period of sending the power control command in this embodiment may be one voice frame, or may be 1/2 voice frames or even shorter, and the shorter the sending period of the power control, the higher the power control frequency.
In an embodiment, as shown in fig. 3, a power control intelligent module included in the semantic link may interact with a wireless environment, the power control behavior is a set of power control commands, the power control commands may be selected from the power control behaviors, after the selected power control commands are executed, the wireless environment may generate a new state, and the power control intelligent module may acquire feedback of the new state.
According to the method, through obtaining various power transmission states and various possible power control commands of the voice link, the power transmission states and the power control commands can be combined respectively, each group of power transmission states and the power control commands can obtain link quality, each link quality corresponds to one rewarding value, the rewarding value corresponding to each possible condition of the voice link can be determined through the method, and the comprehensiveness of rewarding value calculation is guaranteed.
As an alternative embodiment, in order to improve accuracy of the transmit power determination, S430 may include:
s610, acquiring the interference signal strength of the voice link in the t-1 period;
s620, determining a first sum value of the link quality of the voice link in the t-1 period and the interference signal strength as a second transmitting power of the voice link in the t-1 period;
s630, determining a first power control command corresponding to the first link quality;
and S640, determining the first transmitting power according to the second transmitting power and the first power control command.
In this embodiment, the link quality is actually the downlink signal-to-noise ratio of the voice link, that is, the ratio of the strength of the received useful signal to the strength of the received interference signal, after the link quality is obtained, the interference signal strength of the voice link may also be obtained, and the first sum of the link quality and the interference signal strength may be determined as the transmit power. The interference signal strength of the voice link can be predicted according to the environment of the cell, and the interference signal strength can be measured in real time.
In an embodiment, after determining the first link quality of the voice link in the t-1 th period, a power control command to achieve the first link quality may be determined according to the first link quality, a first sum of the link quality in the t-1 th period and the interference signal strength in the t-1 th period may be determined as a second transmission power of the voice link in the t-1 th period, and then the first transmission power may be determined according to the second transmission power and the first power control command.
For example, the calculation formula of the second transmission power of the t-1 th period may be:
P T [t-1]＝γ [t-1] +I [t-1]
wherein t-1 represents the t-1 th period, P T [t-1]Representing the second transmit power, gamma, of the t-1 th period voice link [t-1] Representing the link quality of the t-1 st period voice link, I [t-1] The interference signal strength of the t-1 th period is indicated.
After the second transmit power is obtained, the first transmit power may be further calculated therefrom as follows:
P T [t]＝P T [t-1]+c(t)
wherein P is T [t-1]Representing the second transmit power, P, of the t-1 th period voice link T [t]For the first transmit power, c (t) is a power control command corresponding to the first link quality, and t represents the t-th period.
By the calculation mode, the link state of the last period can be determined according to the signal interference condition and the signal to noise ratio, and the first transmitting power can be determined according to the link state of the last period and the power control command, so that the accuracy of transmitting power determination is improved.
As an alternative embodiment, the above-mentioned reward function may include:
s710, in the case that the absolute value of the second difference value between the first link quality and the target quality is smaller than a first threshold value, the reward value is a first reward value;
s720, in the case that the absolute value of the second difference value between the first link quality and the target quality is larger than a second threshold value, the rewarding value is a second rewarding value;
s730, where the absolute value of the second difference between the first link quality and the target quality is greater than a first threshold and less than a second threshold, the prize value is a third prize value, where the first prize value is greater than the second prize value and the second prize value is greater than the third prize value.
In this embodiment, the reward function may be determined based on the target quality, the link quality in the t-1 th period, and the link quality in the t-1 th period. Specifically, the reward function may be as follows:
wherein, sigma and rho are preset thresholds according to actual demands, sigma is a first threshold, the first threshold can be set between 1 and 2, rho is a second threshold, the second threshold can be set between 5 and 10, ra is a median value of rewarding values, and gamma is a median value of rewarding values tar Is the target quality; gamma ray [t] For the link quality of the t-th period, gamma [t-1] Link quality, r, for the t-1 th period t Is a prize value.
According to the reward function, it can be known that the reward value is the largest under the condition that the link quality of the t-th period is smaller than the target quality; in the case that the link quality of the t-th period is greater than the second threshold from the target quality, the reward value is minimum; in the case where the link quality of the t-th cycle is equal to or less than the second threshold value and equal to or greater than the first threshold value from the target quality, the bonus value may be further determined based on a comparison of the link quality of the t-th cycle and the link quality of the t-1 th cycle.
