Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The communication link determining method provided by the present application can be applied to the application environment shown in fig. 1, and is particularly applied to a communication link determining system. The communication link determination system includes a terminal 102 and a server 104, wherein the terminal 102 communicates with the server 104 through a network. The server 104 executes a communication link determination method, specifically, obtains a communication link set; analyzing reflection plane information of candidate communication links in the communication link set based on the number of the communication links in the communication link set to obtain possible reflection plane information corresponding to each candidate communication link; processing the possible information of each reflection plane to obtain at least one possible information combination of the reflection planes corresponding to the communication link set; processing the possible information combination of the reflecting planes according to the constraint conditions of the reflecting planes to obtain the possible information combination of the target reflecting planes; and determining each target communication link in the communication link set by using each target reflection plane possible information in the target reflection plane possible information combination. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
The communication link determination method of the present invention is described below in conjunction with fig. 2-7.
In one embodiment, as shown in fig. 2, a communication link determining method is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
step 202, a set of communication links is obtained.
Specifically, the communication link refers to a link formed between two communication devices, which is capable of communication. For example, if there are device i, device j, and device k within communication range, there are 3 communication links, i.e., the communication link between device i and device j, the communication link between device i and device k, and the communication link between device j and device k.
Specifically, the server may obtain the communication link set according to any one device in the communication range as the transmission device. For example, in a cellular network with multiple D2D (Device to Device Communication), a base station is used as a Communication transmitting Device, terminals in the cellular network are used as receiving devices, and the number of Communication links is determined according to the number of terminals to obtain a Communication link set.
And 204, analyzing the reflection plane information of the candidate communication links in the communication link set based on the number of the communication links in the communication link set to obtain possible reflection plane information corresponding to each candidate communication link.
Wherein the reflection plane information refers to information using a reflection plane on the communication link. For example, the reflection plane information includes information of which reflection plane is not used on the communication link or used on the communication link and which reflection plane is used, and the like.
Specifically, after the server acquires the communication link set, based on the number of links in the communication link set, the possible information of the reflection plane corresponding to each candidate communication link may be obtained.
In one embodiment, the server may obtain the reflection plane possibility information corresponding to each candidate communication link according to an exponential relationship between the number of links in the communication link set and the reflection plane possibility. For example, if the number of links in the communication link set is 10, and the reflection plane probability of each communication link is 2, the total possible information count of the reflection plane corresponding to each candidate communication link is 2 according to the exponential relationship between the number of links and the reflection plane probability10And (4) seed preparation.
And step 206, processing the possible information of each reflection plane to obtain at least one possible information combination of the reflection planes corresponding to the communication link set.
Specifically, after obtaining the possible information of the reflection plane corresponding to each candidate communication link, the server may freely combine the possible information of the reflection plane to obtain at least one possible information combination of the reflection plane. For example, one of the possible information combinations for the reflection plane is { { communication link 1, without reflection plane }, { communication link 2, with reflection plane a }, … … { communication link 10, with reflection plane Z } }.
And step 208, processing the possible information combination of the reflecting planes according to the constraint conditions of the reflecting planes to obtain the possible information combination of the target reflecting planes.
The reflecting plane constraint condition means that possible information combinations of the reflecting planes can meet certain constraint conditions. For example, the reflecting plane constraint is to cause the average transmission rate of the communication links in the possible information combinations of the reflecting plane to reach the transmission rate threshold. The transmission rate threshold value is a critical value of the transmission rate, and the transmission rate is considered to be the transmission rate meeting the condition when the transmission rate is larger than the critical value; the transmission rate is equal to or less than the transmission rate considered as the transmission rate not satisfying the condition.
Specifically, after obtaining the possible information combination of the reflection plane, the server continuously adjusts the possible information of the reflection plane of each communication link in the possible information combination of the reflection plane until the constraint condition of the reflection plane is satisfied.
And step 210, determining each target communication link in the communication link set by using each target reflection plane possible information in the target reflection plane possible information combination.
Specifically, after obtaining the possible information combination of the target reflection planes, the server determines each target communication link by using the possible information of the target reflection planes in the possible information combination of the target reflection planes. For example, the target reflection plane may be combined with information { [ communication link 1, using reflection plane a ], [ communication link 2, using reflection plane B ], … … [ communication link 10, not using reflection plane ] }; { [ communication link 1, without use of a reflection plane ], [ communication link 2, with use of a reflection plane a ], … … [ communication link 10, without use of a reflection plane ] }; … … { [ communication link 1, without use of a reflection plane ], [ communication link 2, with reflection plane a ] } … … [ communication link 10, without use of a reflection plane ] } }, the respective communication links 1 are arranged according to the reflection plane possible information in the combination, resulting in a target communication link. For example, a reflection plane is used on the communication link 1 and the reflection plane used is a.
In the method for determining the communication link, a communication link set is obtained; analyzing the reflection plane information of the candidate communication links in the communication link set based on the number of the communication links in the communication link set to obtain possible reflection plane information corresponding to each candidate communication link; processing the possible information of each reflection plane to obtain at least one possible information combination of the reflection planes corresponding to the communication link set; processing the possible information combination of the reflecting planes according to the constraint conditions of the reflecting planes to obtain the possible information combination of the target reflecting planes; and determining each target communication link in the communication link set by using each target reflection plane possible information in the target reflection plane possible information combination. The target communication links in the communication link set can be quickly determined through the target reflection plane possible information, and therefore the communication link determination efficiency is improved.
In one embodiment, as shown in fig. 3, the reflecting plane constraint includes that the transmission rate statistic corresponding to the possible information combination of the target reflecting plane reaches the transmission rate threshold; processing the possible information combination of the reflecting planes according to the constraint condition of the reflecting planes to obtain the possible information combination of the target reflecting planes, wherein the possible information combination of the target reflecting planes comprises the following steps:
step 302, a communication link corresponding to each candidate reflecting plane possible information in the reflecting plane possible information combination is obtained.
Specifically, the server analyzes possible information of each candidate reflection plane in the acquired possible information combination of the reflection planes, and obtains a communication link corresponding to the possible information of each candidate reflection plane according to a one-to-one correspondence relationship between the possible information of the reflection planes and the communication link. For example, the candidate reflection plane may be "using reflection plane a" and correspond to communication link 1. Likewise, individual communication links may be obtained.
Step 304, the transmission rate of each communication link is counted to obtain a transmission rate statistic value.
Specifically, after determining the communication link, the server performs statistics on the transmission rate of the communication link in the possible information of each candidate reflection plane to obtain a transmission rate statistic value. For example, the candidate reflection plane possible information is { [ communication link 1, using reflection plane a ], [ communication link 2, using reflection plane B ], … … [ communication link 10, not using reflection plane ] }, the transmission rate of each of 10 communication links in the candidate reflection plane possible information is calculated, the transmission rate of each communication link is obtained, and the average value of the transmission rates of the communication links is calculated, so as to obtain a transmission rate statistic.
And step 306, adjusting the possible information combination of the reflecting planes to obtain the possible information combination of the middle reflecting plane.
Specifically, the server may adjust possible information of each reflection plane in the possible information combinations of the reflection planes to obtain a possible information combination of the middle reflection plane.
In one embodiment, the reflection plane information corresponding to the preset number of communication links in the first reflection plane possible information in the reflection plane possible information combination may be exchanged with the reflection plane information corresponding to the preset number of communication links in the last reflection plane possible information, the reflection plane information corresponding to the preset number of communication links in the second reflection plane possible information may be exchanged with the reflection plane information corresponding to the preset number of communication links in the penultimate reflection plane possible information, and so on, to obtain a new reflection plane possible information combination, which is used as the middle reflection plane possible information combination. For example, the reflection planes may be combined into { [ communication link 1, using reflection plane a ], [ communication link 2, using reflection plane B ], … … [ communication link 10, not using reflection plane ] }; { [ communication link 1, without use of a reflection plane ], [ communication link 2, with use of a reflection plane a ], … … [ communication link 10, without use of a reflection plane ] }; … … { [ communication link 1, not using reflection plane ], [ communication link 2, using reflection plane a ], … … [ communication link 10, not using reflection plane ] } }, the intermediate reflection planes after adjustment may be combined into { [ communication link 1, not using reflection plane ], [ communication link 2, using reflection plane a ], … … [ communication link 10, not using reflection plane ] }; { [ communication link 1, without use of a reflection plane ], [ communication link 2, with use of a reflection plane a ], … … [ communication link 10, without use of a reflection plane ] }; … … { [ communication Link 1, use reflection plane A ], [ communication Link 2, use reflection plane B ], … … [ communication Link 10, not use reflection plane ] }.
And 308, executing a step of acquiring communication links corresponding to the possible information of each candidate reflecting plane in the possible information combination of the reflecting planes by using the possible information combination of the middle reflecting plane until the transmission rate statistic value reaches a transmission rate threshold value.
Specifically, the server continuously adjusts the possible information combination of the reflection planes until the corresponding communication of the possible information of each candidate reflection plane in the possible information combination of the reflection planesAnd the transmission rate statistic corresponding to the signal link reaches the transmission rate threshold. For example, the 1 st possible information of the reflection plane in the possible information combination of the reflection planes is [ communication link 1, using reflection plane a][ communication Link 2, using reflection plane B]… … [ communication Link 10, without the use of reflective planes]Then, the transmission rate statistic is calculated for the corresponding 10 communication links in the possible information of the reflecting plane, and when the calculated transmission rate statistic reaches the transmission rate threshold, the adjustment of the possible information combination of the reflecting plane is finished. For example, the transmission rate of the communication link 1 is represented as R1, the transmission rate of the communication link 2 is represented as R2 … …, the transmission rate of the communication link 10 is represented as R10, and the transmission rate statistic is represented as R10
Then the transmission rate statistic
Expressed as the formula:
in this embodiment, the possible information combination of the reflection plane and the calculation of the transmission rate statistic value can be adjusted by obtaining the communication links corresponding to the possible information of each candidate reflection plane in the possible information combination of the reflection plane, counting the transmission rate of each communication link to obtain a transmission rate statistic value, adjusting the possible information combination of the reflection plane to obtain a possible information combination of an intermediate reflection plane, and performing the step of obtaining the communication links corresponding to the possible information of each candidate reflection plane in the possible information combination of the reflection plane by using the possible information combination of the intermediate reflection plane until the transmission rate statistic value reaches the transmission rate threshold value.
In an embodiment, as shown in fig. 4, the constraint condition of the reflection plane includes that the adjustment times corresponding to the possible information combination of the target reflection plane reaches a time threshold, and the processing the possible information combination of the reflection plane according to the constraint condition of the reflection plane to obtain the possible information combination of the target reflection plane includes:
step 402, adjusting each piece of possible information of the reflection planes in the possible information combination of the reflection planes to obtain the adjustment times.
Specifically, the server obtains the number of times of adjustment by obtaining the use condition of each communication link to the reflection plane in each piece of possible information of the reflection plane in the possible information combination of the reflection plane and adjusting the use condition of each communication link to the reflection plane.
In one embodiment, assuming that the possible reflection plane information sets are { reflection plane possible information 1, reflection plane possible information 2 … … reflection plane possible information 40}, and each of the possible reflection plane information sets includes the reflection plane usage of 10 communication links, when the adjustment number is 1, the reflection plane usage of the first 5 communication links in the reflection plane possible information 1 and the reflection plane usage of the first 5 communication links in the reflection plane possible information 40 are adjusted; when the number of times of adjustment is 2, adjusting the use condition of the reflection plane of the first 5 communication links in the reflection plane possibility information 2 and the use condition of the reflection plane of the first 5 communication links in the reflection plane possibility information 39; and repeating the steps in the same order, and repeating the steps until the transmission rate statistic value of 10 communication links corresponding to the possible information of each reflection plane reaches the transmission rate threshold value, and finishing the adjustment to obtain the adjustment times.
In step 404, if the adjustment times reach the time threshold, it is determined that the current possible information combination of the reflection planes is the possible information combination of the target reflection planes.
Specifically, after the server obtains the adjustment times, if the adjustment times reach a time threshold, the server determines the possible information combination of the current reflection plane, which needs to be obtained after the last adjustment, as the possible information combination of the target reflection plane.
In this embodiment, the adjustment times are obtained by adjusting each piece of possible information of the reflection planes in the possible information combinations of the reflection planes, and if the adjustment times reach the time threshold, it is determined that the current possible information combination of the reflection planes is the possible information combination of the target reflection planes, so that the purpose of accurately obtaining the possible information combination of the target reflection planes according to the adjustment times as the limiting condition can be achieved.
In an embodiment, as shown in fig. 5, analyzing reflection plane information of candidate communication links in the communication link set based on the number of communication links in the communication link set, and obtaining possible reflection plane information corresponding to each candidate communication link includes:
step 502, obtaining possible conditions of reflection plane information; this possibility includes the use of a reflective plane and the non-use of a reflective plane.
Specifically, the server may obtain the possible situation of the reflection plane information through the value of the communication link selection variable, and when the value of the communication link selection variable is 1, it indicates that the reflection plane is used in the communication link; when the value of the communication link selection variable is 0, it indicates that no reflection plane is used in the communication link.
And step 504, obtaining possible information of the reflection plane corresponding to each candidate communication link according to the exponential relation between the number of the communication links and the possible situation.
Specifically, after the server obtains the possible situations of the reflection plane information, the possible situations are taken as the base number, and the number of the communication links is taken as the index number, so that the reflection plane possible information corresponding to each candidate communication link is obtained. For example, the possible situations are 2, and assuming that the number of communication links is 10, the total number of possible information of the reflection plane corresponding to each candidate communication link is 210And (4) respectively.
In this embodiment, the possible information of the reflection plane corresponding to each candidate communication link is obtained by obtaining the possible situation of the information of the reflection plane and according to the exponential relationship between the number of the communication links and the possible situation, so that the purpose of accurately obtaining the possible information of the reflection plane can be achieved.
In one embodiment, as shown in fig. 6, the communication link determining method further includes:
step 602, obtaining transmission rates of each candidate communication link in the communication range.
The communication range refers to a range in which the communication device can communicate.
Specifically, the server is connected with the monitoring device, and receives a monitoring signal sent by the monitoring device of the communication signal, where the monitoring signal includes a transmission rate, so as to obtain the transmission rate of each candidate communication link in the communication range.
Step 604, processing each transmission rate to obtain a statistical transmission rate.
The statistical transmission rate is a transmission rate capable of representing the overall situation of the transmission rate. Specifically, after acquiring the transmission rates of the candidate communication links, the server may use an average transmission rate of the transmission rates as a statistical transmission rate or may use a median transmission rate of the transmission rates as the statistical transmission rate.
And 606, processing the statistical transmission rate by using the transmission rate constraint condition to obtain the target transmission rate.
The transmission rate constraint condition is a condition that enables the transmission rate to reach the target transmission rate.
Specifically, after the server obtains the statistical transmission rate, the server processes the statistical transmission rate corresponding to each candidate communication link according to the transmission rate constraint condition until the statistical transmission rate corresponding to at least one of the candidate communication links reaches the transmission rate threshold, and the statistical transmission rate corresponding to the last adjustment of each candidate communication link is taken as the target transmission rate.
Step 608, based on the target transmission rate, performs the step of obtaining the set of communication links.
Specifically, after obtaining the target transmission rate, the server takes the last adjustment of the corresponding statistical transmission rate of each candidate communication link as the target transmission rate, and executes the steps to obtain the communication link set according to the corresponding relationship between the target transmission rate and the communication link identifier. For example, taking 5 communication links in the communication range as an example, the communication link identifier is identified in a digital form, { { communication link 1 with a target transmission rate of 144kb/s }, { communication link 2 with a target transmission rate of 128kb/s }, { communication link 3 with a target transmission rate of 105kb/s }, { communication link 4 with a target transmission rate of 130kb/s }, { communication link 5 with a target transmission rate of 100kb/s } }, and assuming that the transmission rate threshold is 120kb/s, the step is executed to obtain the set of communication links, which is { communication link 1, communication link 2, and communication link 4 }.
In this embodiment, the transmission rate of each candidate communication link in the communication range is obtained, each transmission rate is processed to obtain a statistical transmission rate, the statistical transmission rate is processed by using a transmission rate constraint condition to obtain a target transmission rate, and the step is executed to obtain the communication link set based on the target transmission rate, so that the communication link set in the communication range can be screened by the transmission rate, and the screening efficiency of the communication links is improved.
In one embodiment, the processing the statistical transmission rate using the transmission rate constraint condition to obtain the target transmission rate comprises: and adjusting the statistical transmission rate in the direction of increasing the transmission rate by taking the current statistical transmission rate as an initial condition until the statistical transmission rate reaches a transmission rate threshold value, so as to obtain the target transmission rate.
Specifically, after the server obtains the statistical transmission rate, the statistical transmission rate is combined with the transmitting power and the like to be used as elements in the four-tuple of the Markov decision process,
defining the state space as S ═ Sd,Sa,SIIn which S isdRepresenting the sum of the distances from the transmitting device to the reflecting plane and from the reflecting plane to the receiving device, SaIndicating the angle of reflection for communication using the plane of reflection. SIInformation indicating characteristics of the transceiving equipment, such as transmission power, transmission rate, or whether there is an occlusion, etc. Defining an action space representation as a ═ ab,AwIn which AbIndicating whether or not a reflecting plane is selected for communication, AwIndicating which plane of reflection is selected for communication. Defining a reward function as representing the signal-to-noise ratio of the communication link, for statistical transmission rate to transmission rate increaseAnd adjusting the direction until the transmission rate threshold is reached, and taking the statistical transmission rate corresponding to the last adjustment as the target transmission rate.
In this embodiment, the target transmission rate is obtained by adjusting the statistical transmission rate in the direction of increasing the transmission rate with the current statistical transmission rate as an initial condition until the transmission rate reaches the transmission rate threshold, so as to achieve the purpose of improving the efficiency of obtaining the target transmission rate.
In one embodiment, as shown in fig. 7, the obtaining of the transmission rate includes:
