Description

Terminal selection method, device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a terminal selection method, apparatus, and storage medium.

Background

At present, when a target terminal similar to a first terminal is selected from a large number of second terminals, the adopted method generally performs rough selection according to the experience of an analyst, and has no more accurate selection standard and no more accurate data support, so that the similar target terminal cannot be accurately selected.

For example, when evaluating the cost of a new user of a Content Delivery Network (CDN) in a CDN Network system, the cost of an old user similar to the cost of the new user is also typically used for evaluation. Selecting similar users similar to the new user from the old users is also a terminal selection method, the new user is equivalent to a first terminal, the old user is equivalent to a second terminal, and the similar users are equivalent to target terminals. For example, to evaluate a new user of a short video class, an old user of a short video of the same class is selected and evaluated according to the cost condition of the old user, but the cost of the user of the same class may be different due to different busy and idle time periods or different source returning conditions, and therefore the selected result is not accurate.

In another embodiment, the terminal device may also retrieve the first data transmission parameter information and the second data transmission parameter information from the server through a network link.

The above example of fig. 1 is only an example of a system architecture for implementing the embodiment of the present invention, and the embodiment of the present invention is not limited to the system architecture shown in fig. 1, and various embodiments of the present invention are proposed based on the system architecture.

The following are detailed below. The numbers in the following examples are not intended to limit the order of preference of the examples.

The present embodiment will be described from the perspective of a terminal selection device, which may be integrated in a terminal device, such as a mobile phone, a tablet Computer, a notebook Computer, or a Personal Computer (PC).

As shown in fig. 2, a terminal selection method is provided, which may be executed by a processor of a terminal device, and the specific flow of the terminal selection method is as follows:

101. and determining the parameter type of the parameter information to be acquired.

The parameter type may be divided according to actual requirements, for example, the parameter information to be acquired may be divided into a first parameter type and a second parameter type based on a hierarchy of servers participating in data transmission, where the parameter information of the first parameter type may include data transmission parameter information between the first terminal or the second terminal and a first hierarchy server in a network, and the parameter information of the second parameter type includes data transmission parameter information between the first terminal or the second terminal and the first hierarchy server in the network, and data transmission parameter information between the first hierarchy server in the network and a second hierarchy server in the network.

For example, the parameter type may be determined by obtaining in advance the data transmission amount between the first terminal and the first-tier server in the network, and the data transmission amount between the first-tier server and the second-tier server.

For example, in an embodiment, the step of determining the parameter type of the parameter information to be acquired includes:

acquiring a first data transmission quantity between the first terminal and a first hierarchical server in a network;

The first data transmission amount may be the number of bytes of data transmitted between the first terminal and the first tier server within a certain preset time period, and correspondingly, the second data transmission amount is the number of bytes of data transmitted between the first terminal and the second tier server within the same preset time period.

In an embodiment, the parameter type may be determined according to a magnitude relationship between the ratio and a certain preset value. For example, if the ratio is greater than a predetermined value, the parameter type is the first parameter type, and if the ratio is less than the predetermined value, the parameter type is the second parameter type. For example, if the ratio of the first data transmission amount to the second data transmission amount is greater than a certain preset value, the data transmission between the first tier server and the second tier server may be ignored, and only the data transmission parameter information between the first terminal and the first tier server is acquired as the first data transmission parameter information. For another example, in another embodiment, the terminal device may obtain the parameter type selected by the user according to the parameter type selection box.

For example, a "parameter type" selection box is set on an interface for acquiring parameter information by the terminal device. The selection box has two options which are respectively a first parameter type and a second parameter type, the user can click the corresponding options, and the terminal equipment can acquire the parameter types selected by the user.

102. And acquiring first data transmission parameter information between the first terminal and a server in the network within a first preset time period according to the parameter type.

The first terminal may be a terminal accessing a server in the network, a terminal acquiring a service of the server in the network, or the like.

The first data transmission parameter information refers to information that can represent a data transmission state between the first terminal and a server in the network, and may include, for example, a data transmission rate, a data transmission amount, and the like. .

In an embodiment, the data transmission information further includes time information, for example, the first data transmission parameter information may include an acquisition time within a first preset time period, and a data transmission parameter corresponding to the acquisition time.

The method for acquiring the first data transmission parameter information may be various, for example, the first data transmission parameter information may be acquired according to a parameter information acquisition instruction. For example, the parameter information obtaining instruction may carry a first preset time period, a terminal device number, a parameter type, and the like set by the user, and the terminal device may analyze the parameter obtaining instruction and obtain corresponding first data transmission parameter information according to the first preset time period, the terminal device number, and the parameter type.

In order to facilitate triggering the command, a command interface may be provided, wherein the representation form of the command interface may be various, for example, the form of an input box, a selection box, an icon, a button, and the like.

In an embodiment, a selection frame of "start time", "end time", and "first terminal number" and a confirmation button may be set on a setting interface for acquiring parameter information, and a user selects a start time point and an end time point in the selection frame, respectively, and inputs a number of a first terminal, at this time, the terminal may acquire a first preset time period and the number of the first terminal, and then when the user clicks the confirmation button, a parameter information acquisition instruction may be triggered, and at this time, the terminal may acquire parameter information of the first terminal in the first preset time period according to the parameter information acquisition instruction, the first preset time period, and the number of the first terminal.

The method for obtaining the first data transmission parameter information based on the parameter type may be various, for example, a parameter type setting selection box may be set on a page of the terminal device, and after the user determines an option in the selection box, the terminal device may obtain the corresponding parameter type, and obtain the first data transmission parameter information from a local storage or from a network side device based on the parameter type.

In an embodiment, to obtain more accurate data transmission similarity and further improve the accuracy of selecting a similar target terminal, different sub-data transmission parameter information may be obtained according to different parameter types as the first data transmission parameter information, and specifically, in an embodiment, the step of obtaining the first data transmission parameter information between the first terminal and a server in the network within a first preset time period according to the parameter types includes:

when the parameter type is a second parameter type, acquiring first subdata transmission parameter information between the first terminal and a first level server in the network and second subdata transmission parameter information between the first level server and a second level server in the network;

The first sub-data transmission parameter information refers to information representing a data transmission state between the first terminal and a first hierarchical server in the network, for example, the first sub-data transmission parameter information may include an acquisition time within a first preset time period and a data transmission parameter corresponding to the acquisition time, and the data transmission parameter may be a data transmission rate.

Accordingly, the second sub-data transmission parameter information is information indicating a data transmission status between the first hierarchical server and the second hierarchical server in the network in response to the request of the first terminal.

103. And acquiring second data transmission parameter information between a second terminal and a server in the network within a second preset time period according to the parameter type, wherein the length of the second preset time period is greater than that of the first preset time period.

Wherein, the second terminal refers to the content of the service or product provided by the network. For example, the second terminal may be a terminal that accesses a server in the network, a terminal that obtains a service of the server in the network, or the like.

The second data transmission parameter information refers to information that may represent a data transmission state between the second terminal and a server in the network, for example, the second data transmission parameter information may include an acquisition time within a second preset time period and a data transmission parameter corresponding to the acquisition time, and the data transmission parameter may be a data transmission rate. And the second preset time period is a set of acquisition times of the second data transmission parameters. That is, the data transmission parameters occurring within the second preset time period are collected as the second data transmission parameters.

In an embodiment, in order to calculate the similarity, the second preset time period includes one or more unit time periods having the same time interval as the first preset time period, and the number of the acquisition time included in each unit time period and the number of the data transmission parameters corresponding to the acquisition time are the same.

In an embodiment, to avoid the similarity calculation difference due to the different busy/idle times, the unit time period may be selected according to the busy/idle time period, for example, one day may be selected as the unit time period.

In an embodiment, acquiring, according to the parameter type, second data transmission parameter information between the second terminal and a server in the network within a second preset time period includes:

when the parameter type is the first parameter type, acquiring third subdata transmission information between the second terminal and a first-level server in the network as second data transmission parameter information;

when the parameter type is a second parameter type, acquiring third subdata transmission parameter information between the second terminal and a first hierarchical server in the network and fourth subdata transmission parameter information between the first hierarchical server and a second hierarchical server in the network;

and obtaining second data transmission parameter information based on the third sub-data transmission parameter information and the fourth sub-data transmission parameter information.

The third sub-data transmission parameter information is information representing a data transmission state between the second terminal and the first hierarchical server in the network, for example, the second sub-data transmission parameter information may include an acquisition time within a first preset time period and a data transmission parameter corresponding to the acquisition time, and the data transmission parameter may be a data transmission rate.

Accordingly, the fourth sub-data transmission parameter information is information indicating a data transmission status between the first tier server and the second tier server in the network in response to the request of the second terminal.

104. Acquiring data transmission similarity between the first terminal and the second terminal based on the first data transmission parameter information and the second data transmission parameter information;

the data transmission similarity is a parameter for measuring the similarity between the data transmission state between the first terminal and the server and the data transmission state between the second terminal and the server.

The first data parameter information comprises a first data transmission parameter and acquisition time corresponding to the first data transmission parameter; the second data parameter information comprises a second data transmission parameter and acquisition time corresponding to the second data transmission parameter;

in an embodiment, acquiring data transmission similarity between the first terminal and the second terminal based on the first data transmission information and the second data transmission parameter information includes:

selecting second data transmission parameter information to be combined from the second data transmission information according to the selection reference time;

combining the second data transmission parameter information to be combined to obtain second combined data transmission parameter information;

and acquiring the data transmission similarity between the first terminal and the second terminal according to the first combined data transmission parameter information and the second combined data transmission parameter information.

And selecting the reference time as the acquisition time of the data transmission parameters to be selected. According to the number of the parameters to be selected and the first preset time period, the selection reference time can be determined, and then the data transmission parameters are selected according to the reference time.

Before using the terminal selection system, the number of parameters corresponding to the parameter types needs to be predefined.

For example, the first parameter type may be predefined to correspond to m parameters, and the second parameter type may correspond to 2m parameters, for example, m parameters may be selected from the first sub data transmission parameter information, and m parameters may be selected from the second sub data transmission parameter information.

In an embodiment, the terminal selection system stores a mapping relationship between the parameter type and the parameter number, and after the parameter type is determined, the corresponding parameter number can be obtained.

In an embodiment, the data transmission parameters acquired at the selection reference time may be selected from the first data transmission parameter information as first data transmission parameters to be combined, and the first data transmission parameters to be combined are sorted and combined according to the acquisition time sequence as first combined data transmission parameter information.

Similarly, the data transmission parameters acquired at the selection reference time are selected from the second data transmission parameter information to serve as second data transmission parameters to be combined, and the second data transmission parameters are sequenced according to the acquisition time sequence and serve as second combined data transmission parameter information.

Therefore, when a target terminal similar to the data transmission of the first terminal is selected, the first data transmission parameter and the second data transmission parameter can be compared and calculated in a one-to-one correspondence mode according to the reference time, the obtained data transmission similarity is obtained according to the reference time, the situation that the data transmission states are different due to different busy and idle times is avoided, and the data transmission similarity degree of the first terminal and the second terminal can be judged more accurately.

In an embodiment, acquiring the data transmission similarity between the first terminal and the second terminal according to the first combined data transmission parameter information and the second combined data transmission parameter information includes:

For example, the comparison object is the first data transmission parameter to be combined and the second data transmission parameter to be combined, and the magnitude comparison result may be classified into magnitude similarity and magnitude dissimilarity.

In an embodiment, whether the magnitude is similar or not may be determined by comparing the value ranges of the data transmission parameters, for example, if the difference between the magnitude of the first to-be-combined data transmission parameter and the magnitude of the second to-be-combined data transmission parameter is small, the magnitude comparison result is that the magnitudes are similar. On the contrary, if the magnitude difference between the value range of the first to-be-combined data transmission parameter and the value range of the second to-be-combined data transmission parameter is large, the magnitude comparison result is that the magnitudes are dissimilar.

In an embodiment, the minimum value, the maximum value and the mode of the first data transmission parameter to be combined and the minimum value, the maximum value and the average value of the second data transmission parameter to be combined may be obtained, and the difference between the minimum value, the difference between the maximum values and the difference between the average values of the two values are correspondingly calculated.

In an embodiment, the terminal may obtain the similarity metric function through the function setting instruction, and obtain the data transmission similarity of the first combined transmission parameter information and the second combined data transmission parameter information according to the similarity metric function. For example, the function setting instruction carries a similarity measurement function set by the user, and the terminal device analyzes the function setting instruction to obtain the similarity measurement function.

For example, a "function type" selection box and a confirmation button are set on the function obtaining interface, the selection box has three options which are an euclidean distance function, a cosine distance function and a custom function, and a user can click the corresponding options to select the similarity measurement function and click the confirmation button to trigger the function setting instruction button.

In an embodiment, a user-defined function is selected, and after a confirmation button is clicked, a function editing page can be entered, and the function editing function can be used as a user-defined similarity measurement function on the function editing page, and the data transmission similarity of the first combined transmission parameter information and the second combined data transmission parameter information is obtained through the user-defined similarity measurement function.

In an embodiment, an interface of the terminal device is provided with a "first terminal number" input box, a "first preset time period" selection box, a "second preset time period" selection box and a confirmation button, and after a user inputs the first terminal number on the interface of the terminal device and selects the first preset time period and the second preset time period, the terminal device may obtain corresponding information, and then click the confirmation button, which may trigger a target terminal selection instruction.

202. And the terminal equipment determines the parameter type of the parameter information to be acquired according to the target terminal selection instruction.

In an embodiment, a parameter type selection box may be set on an interface for acquiring parameter information by a terminal device, a user may select a first parameter type or a second parameter type in the selection box, and the terminal device acquires the parameter type selected by the user.

After the user determines the contents of all the selection boxes and the input boxes and triggers the target terminal selection instruction, the terminal device can acquire corresponding data transmission parameter information according to the target terminal selection instruction.

In an embodiment, the terminal device is further provided with a function type selection box, as shown in fig. 4a, when a similar user of a new user of some content distribution network is selected, an appid input box, a start time selection box, an end time selection box, a data source month selection box, a comparison data type selection box, a distance algorithm selection box and a submit button may be set on the interface of the terminal device. The number of the new user can be input into the appid input box, and the first preset time is determined according to the starting time selection box and the ending time selection box and serves as a parameter acquisition time set of the new user. A second preset time may be determined in the data source month selection box as the set of parameter acquisition times for the old user.

Wherein comparing the data types comprises selecting a comparison OC bandwidth or selecting an edge and a comparison intermediate source bandwidth. In some content distribution networks, the content in the origin server is cached in the edge, and when the user uses the network, the user generally only needs to send a request to the edge server, and the edge server can respond. If the edge server does not have the information needed by the user or the source server is updated, the edge server sends a request to the source server and can respond to the request of the user. When the comparison OC bandwidth is selected, only the data transmission status between the new user and the edge server needs to be compared with the data transmission status between the old user and the edge server. When comparing the edge and intermediate source bandwidths is chosen, it is also necessary to compare the data transmission status between the edge server and the intermediate source server in response to the requests of the new user and the old user.

The distance algorithm is a similarity measurement function, and the distance algorithm selection box is a function type selection box. The distance algorithm comprises two choices of trend similarity and magnitude similarity, the selection trends are similar, and the terminal equipment calculates the data transmission similarity by adopting an Euclidean distance formula; and if the selected magnitudes are similar, the terminal equipment calculates the data transmission similarity by adopting a cosine distance formula.

Wherein the new user refers to a user of the first terminal and the old user refers to a user of the second terminal. Bandwidth data is a data transmission parameter. The terminal device may calculate the data transmission similarity using the test bandwidth data in the first preset time period and the bandwidth data in the second preset time period.

In another embodiment, the terminal device does not set the parameter type selection box on the page, and the terminal device may obtain a first data transmission amount between the first terminal and a first tier server in the network and a second data transmission amount between the first tier server in the network and a second tier server in the network. And obtaining the ratio of the two, and then obtaining the parameter type according to the ratio of the two.

For example, if the ratio of the first data transmission amount to the second data transmission amount is greater than a predetermined value, the parameter type is the first parameter type. If the ratio is smaller than the preset value, the parameter type is a second parameter type.

After the parameter type, the first preset time period, the second preset time period and the first terminal number are determined, corresponding data transmission parameter information can be obtained according to the parameter type, the first preset time period, the second preset time period and the first terminal number.

203. And the network equipment in the system acquires the first data transmission parameter information and the second data transmission parameter information according to the parameter types.

In an embodiment, the terminal device may obtain corresponding first data transmission parameter information from the local storage according to the parameter type.

For example, when the parameter type is the first parameter type, data transmission between the first tier server and the second tier server may be omitted, and only the first sub-data transmission parameter information is acquired as the first data transmission parameter information, and only the third sub-data transmission parameter information is acquired as the second data transmission parameter information, so that it is also relatively simple to calculate the similarity.

Accordingly, when the parameter type is the second parameter type, data transmission between the first tier server and the second tier server is not negligible. The first sub data transmission parameter information and the second sub data transmission parameter information must be obtained as the first data transmission parameter information. Likewise, third sub-data transmission parameter information and fourth sub-data transmission parameter information are acquired as second data transmission parameter information. When the data transmission similarity is obtained, the first sub-data transmission parameter information and the third sub-data transmission parameter information, and the second sub-data transmission parameter information and the fourth sub-data transmission parameter information must be correspondingly compared, so that the target terminal with the data transmission state similar to that of the first terminal can be obtained.

In one embodiment, for example, in some content distribution networks, the content in the source server is cached in the edge, and when the user uses the network, the user generally only needs to send a request to the edge server, and the edge server can respond, and at this time, only data transmission occurs between the user and the edge server, so that the first sub-data transmission parameter information is used as the first data transmission parameter information. If the edge server does not have information required by the user or the source server is updated, the edge server sends a request to the source server and can respond to the request of the user, and at the moment, data transmission occurs between the user and the edge server and between the edge server and the source server. Accordingly, the first data transmission parameter information includes first sub data transmission parameter information and second sub data transmission parameter information. The edge server is a first-level server, the source server is a second-level server, and the user is a user of the first terminal.

In another embodiment, the terminal device may also obtain the corresponding first data transmission parameter information from the server through the network link.

204. And the terminal equipment acquires the data transmission similarity between the first terminal and the second terminal based on the first data transmission parameter information and the second data transmission parameter information.

For example, after the terminal device obtains the first data transmission parameter information and the second data transmission parameter information, the data transmission similarity may be calculated according to a similarity measurement function.

Before calculating the data transmission similarity, the first data transmission parameter to be combined and the second data transmission parameter to be combined are selected according to the number of parameters corresponding to the parameter types.

For example, the parameter number corresponding to the parameter type may be predefined in the terminal device, the reference time may be selected according to the parameter number and the first preset time period, the first to-be-combined data transmission parameter may be selected from the first data transmission parameter information according to the reference time, and the second to-be-combined data transmission parameter may be selected from the second data transmission parameter information.

For example, the number of parameters corresponding to the first parameter type may be predefined as m; the number of the parameters corresponding to the second parameter type is 2m, and the parameters include m first sub data transmission parameters and m second sub data transmission parameters.

For example, a first parameter type may be predefined to include 288 data transmission parameters per unit time period, a second parameter type may correspond to 576 data transmission parameter information per unit time period, the unit time period is one day, the first preset time period is one day, and then the meaning of selecting the reference time is to collect the data transmission parameters every 5 minutes.

The data transmission parameters selected according to the selection reference time can better correspond to each other, because the acquisition time of the first data transmission parameters contained in the first data transmission parameter information is the same as the acquisition time of the second data transmission parameters contained in the second data transmission parameter information in position within the unit time period.

For example, the first data transmission parameter and the second data transmission parameter acquired at 0 point and 5 points of each day may be selected as the first data transmission parameter to be combined and the second data transmission parameter to be combined, respectively.

The data transmission similarity can be calculated by converting the data transmission parameters to be combined and the second data transmission parameters to be combined into a first eigenvector and a second eigenvector, and substituting the first eigenvector and the second eigenvector into a similarity measurement function.

The first eigenvector is a multidimensional vector formed by first data transmission parameters according to the acquisition time of the first data transmission parameters, and the second eigenvector is a multidimensional vector formed by second data transmission parameters according to the acquisition time of the second data transmission parameters.

The terminal device can select the similarity metric function through magnitude comparison.

For example, when the equivalence levels are similar, the data transmission similarity can be obtained by calculating the euclidean distance, and when the equivalence levels are not similar, the data transmission similarity can be obtained by the included angle parameter.

The terminal device may determine whether the magnitudes are similar by comparing the minimum value, the maximum value, and the average value of the first data transmission parameter to be combined and the second data transmission parameter to be combined.

The terminal device may also select the similarity metric function by accepting a function setting instruction or a target terminal selection instruction.

In an embodiment, the terminal device may further calculate the similarity through a custom function, and details of the steps are not described again.

For example, in one embodiment, the Euclidean distance may be calculated using the following formula:

then, normalization processing needs to be performed on the euclidean distance to obtain data transmission similarity between the first combined transmission parameter information and the second combined data transmission parameter information, and in an embodiment, normalization processing may be performed by using the following formula:

the value range of d' obtained after normalization treatment is [0, 1 ]. Therefore, the terminal equipment can judge the similarity degree according to the data transmission similarity d obtained by calculation. Specifically, it may be predefined that the closer the data transmission similarity is to 1, the higher the similarity is, and the closer the data transmission similarity is to 0, the lower the similarity is. Thus, the terminal device can select the target terminal according to the data transmission similarity value.

For example, in one embodiment, the cosine of the included angle may be calculated by the following formula;

normalizing the cosine of the included angle to obtain the data transmission similarity of the first combined transmission parameter information and the second combined data transmission parameter information, wherein in an embodiment, the normalization can be performed by using the following formula:

d＝0.5+0.5×d′

the value range of d' obtained after normalization treatment is [0, 1 ]. Therefore, the terminal equipment can judge the similarity degree according to the data transmission similarity data. Specifically, it may be predefined that the closer the data transmission similarity is to 1, the higher the similarity is, and the closer the data transmission similarity is to 0, the lower the similarity is. Thus, the terminal device can select the target terminal according to the data transmission similarity value.

205. And the terminal equipment selects a target terminal similar to the data transmission of the first terminal from the second terminal based on the data transmission similarity.

And sequencing the calculated data transmission similarity from large to small, selecting a preset number of second terminals as target terminals, and outputting and displaying the target terminals on a display page of the terminal equipment.

For example, 5 second terminals with the highest data transmission similarity may be selected as the target terminal in the terminal device in a predefined manner.

The terminal selection system of the present invention may also select a second terminal that is least similar to the first terminal as the target terminal, for example, predefined and selected 10 second terminals with the lowest data transmission similarity in the terminal device as the target terminal.

In an embodiment, the terminal selection system may store a mapping relationship between the second terminal and its bandwidth trend graph. After the target terminal is determined, the terminal device can also output a number corresponding to the target terminal.

The output content may be presented in various forms, for example, the number of the target terminal, the data transmission parameter change information of the target terminal, and the data transmission similarity between the target terminal and the first terminal may be output. In an embodiment, the output pages shown in fig. 4b to 4g sequentially show the bandwidth trend graph and the similar results of the first terminal, where the similar results include the bandwidth trend graph, the number and the data transmission similarity between the bandwidth trend graph and the number of the plurality of target terminals and the first terminal, and the plurality of target terminals are sequentially arranged from large to small according to the data transmission similarity.

In an embodiment, the terminal device further generates a first data transmission rate variation trend graph and a second data transmission rate variation trend graph according to the first data transmission parameter information and the second data transmission parameter information, respectively.

For example, after the target terminal is determined, the number of the first terminal, the first data transmission rate variation trend graph, the number of the target terminal, the data transmission rate variation trend graph of the target terminal, and the data transmission similarity between the target terminal and the first terminal may be displayed on the display page of the terminal device.

As can be seen from the above, in the embodiment of the present invention, based on the instruction of the user, the data transmission parameter information between the first terminal and the server in the network, and the data transmission parameter information between the second terminal and the server in the network, the data transmission similarity is calculated, and then the target terminal similar to the data transmission of the first terminal is selected from the second terminal according to the data transmission similarity. Since the data transmission similarity is provided as data support, the terminal device can more accurately select the target terminal most similar to the first terminal.
