s101: and performing radio frequency fingerprint acquisition.

Here, the terminal starts the acquisition of the radio frequency fingerprint, so that the corresponding radio frequency fingerprint can be acquired. In practical application, the acquisition of the radio frequency fingerprint can be started after the terminal enters the corresponding area, so that the radio frequency fingerprint information corresponding to the area where the terminal is located can be acquired, for example, when the terminal enters a subway station or enters a bus station, the terminal performs the acquisition of the radio frequency fingerprint information, and in the process of performing the acquisition of the radio frequency fingerprint, the terminal periodically acquires the corresponding radio frequency fingerprint, so that the power consumption of the terminal can be reduced. In practical application, for radio frequency fingerprint acquisition, the terminal can acquire corresponding characteristics according to table 1.

TABLE 1

In one embodiment, the performing radio frequency fingerprinting includes:

Here, in practical application, for some users, there is a requirement for user recommendation of the same train, and for other users, there is no need to perform user recommendation of the same train, so that the user determines whether to enable the function of obtaining the user recommendation information according to the radio frequency fingerprint information by changing the open state or the closed state of the first function on the first terminal, thereby being capable of meeting the personalized requirement of the user and performing corresponding custom setting. When the first function of the first terminal is in an open state, the fact that the user needs to acquire the user recommendation information of the same train is indicated, then the radio frequency fingerprint is collected, and corresponding user recommendation information is generated for the user.

In the above embodiment, when the first function of the first terminal is in an open state, the radio frequency fingerprint acquisition is performed; the first function representation has the function of obtaining the user recommendation information based on the radio frequency fingerprint information, and can meet the requirements of different users for recommendation, so that the user information recommendation can be realized more accurately.

S102: uploading the acquired first radio frequency fingerprint information of the first set reference point to a server; the first set reference point is one of a plurality of set reference points arranged on at least one set traffic route.

Here, the terminal uploads the acquired first radio frequency fingerprint information to the server in real time, and the first radio frequency fingerprint acquired by the terminal is a radio frequency fingerprint located at one position on a set traffic route and can correspond to a set reference point arranged on the traffic route. In practical applications, a plurality of set reference points may be disposed on a set traffic route, for example, for a subway traffic route, the disposed set reference points may include a subway station hall, a subway station platform, and a track interval between two adjacent subway stations, generally, a set reference point may be disposed at a middle position of each subway station platform, each subway station hall may be disposed with one or more set reference points according to the size of the station hall and the wireless environment in the station hall, and a plurality of set reference points may be disposed between two adjacent subway stations according to the track length and the wireless environment in the track, wherein, for the same area, the principle of disposing the set reference points is that there is a significant difference according to the radio frequency fingerprint characteristics between the reference points, for example, different set reference points may be disposed according to the difference of physical IDs of the cells, therefore, the corresponding set reference point can be determined according to the radio frequency fingerprint characteristics. In practical applications, there may be multiple subway lines in one subway station, as shown in fig. 2, fig. 2 shows a partial perspective view of the subway station, wherein, in fig. 2, a subway line 1 and a subway line 2 are intersected at a subway station X, the uppermost layer is a subway station hall of the subway station X, the subway line 1 is located at the middle layer of the subway station X, the subway line 2 is located at the lowermost layer of the subway station X, assuming that the total number of up-down lines of the whole subway line 1 and the whole subway line 2 is 3 platforms, the platform of the subway line 1 at the subway station X is an a platform, the platform of the subway line 2 at the subway station X is a B platform, triangles located on the subway line 1 and the subway line 2 are marked as set reference points for layout, 3 set reference points are distributed in a subway station hall of a subway station X, and 1 set reference point is distributed on each of a platform A and a platform B.

S103: receiving second information returned by the server based on the matching result of the first radio frequency fingerprint information and the plurality of set reference points; the second information represents user information corresponding to a terminal of which the first terminal is located in the same train traveling on the set traffic route.

The terminal uploads the acquired first radio frequency fingerprint information to the server and then can receive second information returned by the server, wherein the second information is generated by matching the first radio frequency fingerprint information reported by the server with a plurality of set reference points arranged on a traffic route, in practical application, one traffic route can be divided into different areas according to different set reference points arranged on the traffic route, the first radio frequency fingerprint information acquired by the terminal is matched with the plurality of set reference points, and the set reference points corresponding to the first radio frequency fingerprint information can be determined mainly by matching the characteristics of the first radio frequency fingerprint information with the characteristics of the radio frequency fingerprint information corresponding to the set reference points. In practical application, when the set reference point corresponding to the first radio frequency fingerprint acquired by the first terminal is located on the track area, it may be determined that the first terminal is currently located on the train traveling on the set traffic route, and thus the determined user information located at the set reference point may be sent to the first terminal, so that the first terminal may obtain the user information of the same train also located on the same set traffic route.

In the above embodiment, the radio frequency fingerprint acquisition is performed; uploading the acquired first radio frequency fingerprint information of the first set reference point to a server; the first set reference point is one of a plurality of set reference points arranged on at least one set traffic route; receiving second information returned by the server based on the matching result of the first radio frequency fingerprint information and the plurality of set reference points; the second information represents user information corresponding to a terminal of the first terminal, wherein the terminal is located in the same train running on the set traffic route, the user information of the same train running on the same traffic route as the terminal can be pushed to the terminal through the radio frequency fingerprint information collected by the terminal and the reference points pre-arranged on the traffic route, the user recommendation information can be accurately generated, and the precision of the user recommendation information is improved.

In an embodiment, the method further comprises:

Here, since the user recommended for the first terminal is a user located on the same train as the first terminal, the first radio frequency fingerprint information collected by the first terminal should be collected when the terminal is located in the area where the set traffic route is located, and when the first terminal leaves the area where the set traffic route is located, it indicates that the first terminal does not need to take the train or leave the train. In practical applications, for most set traffic routes, when the first terminal enters or leaves a station, the gate needs to be passed, so that whether the first terminal enters or leaves the area range of the set traffic route can be determined by determining whether the first terminal passes the gate. For example, card swiping information corresponding to a travel application or Near Field Communication (NFC) on the first terminal may be detected, and the first terminal may be clearly determined to enter or leave the area range where the set transportation route is located through the card swiping information. In practical applications, the location information of the first terminal may also be used to determine, for example, when the current location information of the first terminal indicates that the first terminal is located at a station on a set traffic route, the radio frequency fingerprint acquisition may be triggered to be performed, and when the current location information of the first terminal indicates that the first terminal leaves a station on a set traffic route, the radio frequency fingerprint acquisition may be stopped to be performed.

In the above embodiment, when it is detected that the first terminal enters the area range where the at least one set traffic route is located, the radio frequency fingerprint acquisition is triggered to be executed; and/or stopping executing the radio frequency fingerprint collection when detecting that the first terminal leaves the area range of the at least one set traffic route, and deducing whether the terminal has the requirement recommended by the users in the same train or not by judging whether the terminal is located in the area range of the set traffic route, so as to trigger or suspend the collection of the radio frequency fingerprint, thereby saving the energy consumption of the terminal and providing high-precision user recommendation information for the terminal.

The embodiment of the application also provides another user recommendation method, and fig. 3 is a flow diagram of the user recommendation method of the embodiment of the application. As shown in fig. 3, the method includes:

s301: receiving first radio frequency fingerprint information acquired by each terminal in a plurality of terminals; each piece of received first radio frequency fingerprint information corresponds to a set reference point; wherein, a plurality of set reference points are arranged on at least one set traffic route.

Here, the server receives first radio frequency fingerprint information collected by a plurality of terminals, wherein the first radio frequency fingerprint information is collected by the terminals on a set traffic route, and in practical application, in order to determine users on the same train, set reference points are usually arranged on different areas on the set traffic route, so that different trains can be distinguished, and therefore, the first radio frequency fingerprint information collected by the terminals can correspond to one set reference point arranged on the set traffic route.

S302: clustering the received plurality of first radio frequency fingerprint information to generate at least one first set; each first set of the at least one first set is composed of first radio frequency fingerprint information with a first similarity larger than a set value.

Here, the received plurality of first radio frequency fingerprint information are clustered, where the clustering is to group similar data in the plurality of data into one group, so that the plurality of data can be divided into different groups, thereby improving the processing efficiency of the data, and here, the first radio frequency fingerprint information with the first similarity greater than a set threshold is divided into one set, so that the received plurality of first radio frequency fingerprint information are divided into at least one first set. In practical application, because the radio frequency fingerprint information corresponding to the same area or the similar place is similar or consistent, the first radio frequency fingerprint information collected by the same first set reference point can be processed uniformly according to the first similarity of the first radio frequency fingerprint information. In practical application, a K-means algorithm or a PAM algorithm can be adopted to perform clustering processing on the received plurality of pieces of first radio frequency fingerprint information.

In an embodiment, as shown in fig. 4, the clustering the received plurality of first radio frequency fingerprint information to generate at least one first set includes:

s401: screening the received radio frequency fingerprint information according to a set condition to generate at least one screening result; the screening result represents first radio frequency fingerprints collected by set reference points distributed on the same set traffic route.

Here, the server can receive first radio frequency fingerprint information reported by different terminals, where the first radio frequency fingerprint information reported by the terminals is collected on different set traffic routes, and the server needs to determine users on the same train, so that in the process of directly clustering all the first radio frequency fingerprint information in a plurality of first radio frequency fingerprint information received by the server, the data amount to be processed is huge, and in practical application, for a set traffic route, users on the same platform are likely to become users on the same train, therefore, in practical application, the received first radio frequency fingerprint information can be screened, where the first radio frequency fingerprint information obtained by collecting set reference points on the same set traffic route from the received first radio frequency fingerprint information, furthermore, the first radio frequency fingerprint information acquired by the set reference points of the same platform on the same set traffic route can be further screened. As shown in fig. 5, fig. 5 shows a schematic diagram of one screening result. In fig. 5, a subway station 1 includes two subway lines, which are a line 1 and a line 2, a platform a is used in the uplink and downlink directions of the line 1, a platform B is used in the uplink and downlink directions of the line 2, and a train 1 and a train 2 are located on a line track between the subway station 2 and the subway station 1, where the train 1 is closer to the subway station 1 and the train 2 is closer to the subway station 2, so that first radio frequency fingerprint information acquired by a terminal on the train 1, first radio frequency fingerprint information acquired by a terminal on the platform a, first radio frequency fingerprint information acquired by a terminal on the platform B, and first radio frequency fingerprint information acquired by a terminal in a station hall of the subway station 1 are determined as a screening result, and the first radio frequency fingerprint information acquired by a terminal on the train 2 can be classified as a screening result corresponding to the subway station 2. In practical application, different situations such as leaving a subway station, leaving a train, entering a train and the like can occur to a corresponding terminal in a screening result, and the situations lead to changes of users on the same train, so that the user changes on the same train can be further accurately obtained through the screening result. In practical application, when the received first radio frequency fingerprint information is screened, the screening is determined based on a position corresponding to the first radio frequency fingerprint information reported last time by the terminal, for example, according to an area determined after the first radio frequency fingerprint information reported last time by the terminal is subjected to cluster analysis, the terminal located at the same site is determined as a corresponding screening result, even if users on a train change, the users located at the same site also change, and therefore the users located on the same train can be determined in the first radio frequency fingerprint information within a limited range. In practical application, when the terminal enters the area where the set traffic route is located for the first time, the first radio frequency fingerprint information acquired when the terminal enters the area where the set traffic route is located can be matched with the second radio frequency fingerprint information corresponding to the set reference points arranged on different traffic routes, so that the corresponding first radio frequency fingerprint information is distributed to the corresponding screening results, and in addition, the screening results corresponding to the first radio frequency fingerprint information acquired by the terminal can be determined through the positioning information of the terminal.

S402: and clustering a plurality of pieces of first radio frequency fingerprint information of each screening result in the at least one screening result to generate at least one first set.

Here, since the screening result is to extract the first radio frequency fingerprint belonging to the same station from the plurality of first radio frequency fingerprints received by the server, and in practical application, the user of the same train on the same set traffic route is also included in the screening result, clustering the plurality of first radio frequency fingerprint information of each screening result in at least one screening result, and classifying different first radio frequency fingerprint information in the same station again, thereby determining the first radio frequency fingerprint information in the same area in the same station, and facilitating improvement of data processing efficiency.

In the above embodiment, the received multiple pieces of first radio frequency fingerprint information are screened according to the set conditions to generate at least one screening result; the screening result represents first radio frequency fingerprints collected by set reference points distributed on the same set traffic route; and clustering the plurality of first radio frequency fingerprint information of each screening result in the at least one screening result to generate at least one first set, and further limiting the determined range of users in the same train, so that the data volume in the data processing process is reduced, the data processing efficiency is improved, and the accuracy of user recommendation information can be improved.

S303: and estimating the area of each first set in the at least one first set based on second radio frequency fingerprint information corresponding to each set reference point in the plurality of set reference points.

The server can obtain and store second radio frequency fingerprint information corresponding to each set reference point in the multiple set reference points, and can estimate the area where each first set is located according to the second radio frequency fingerprint information corresponding to each set reference point. In practical application, because the first radio frequency fingerprint information in the same first set has similarity, it indicates that the areas corresponding to the first radio frequency fingerprint information in the first set are also very similar, so that the area where the determined first set is located can be regarded as the position information corresponding to each first radio frequency fingerprint information in the first set, and the position of the corresponding terminal can be determined.

S304: determining the at least one second set based on the area of each first set in the at least one first set; the second set characterizes the first set that matches in area the same train traveling on the set traffic route.

Here, the server needs to acquire the user information on the same train on the set traffic route, and can determine the terminal of the same train on the set traffic route through the area where the first set is located, thereby determining the second set. In practical applications, since a user on a running train does not change, the first set in the same area between two stations can be determined as the second set, for example, as shown in fig. 6, fig. 6 is a schematic diagram illustrating the determination of the second set, a set reference point 1 and a set reference point 2 are arranged between a station a and a station B, the first set in which the area of the first set is located at the set reference point 1 is determined as the second set, and the first set in which the area of the first set is located at the set reference point 2 is determined as the second set, so that the terminal of the same train running on the set traffic route can be determined according to the area of each first set.

S305: sending second information to each terminal corresponding to each second set; and the second information represents the user information corresponding to other terminals in the second set.

Here, each terminal in the second set is located at a terminal of the same train that travels on the set traffic route, the server is capable of collecting user information corresponding to each terminal in the second set, for example, a user name of each terminal in the second set may be determined, the server sends the collected user information to each terminal in the second set, and in practical applications, recommendation information that each terminal needs to obtain should be user information corresponding to other terminals except the terminal, so when the server sends the second information to each terminal in the second set, the server sends the user information corresponding to other terminals in the second set to the corresponding terminal, so that each terminal can obtain recommendation information of other users in the same train.

In the above embodiment, first radio frequency fingerprint information collected by each of a plurality of terminals is received; each piece of received first radio frequency fingerprint information corresponds to a set reference point; wherein, a plurality of set reference points are arranged on at least one set traffic route; clustering the received plurality of first radio frequency fingerprint information to generate at least one first set; each first set in the at least one first set consists of first radio frequency fingerprint information with first similarity larger than a set value; estimating the area of each first set in the at least one first set based on second radio frequency fingerprint information corresponding to each set reference point in the plurality of set reference points; determining the at least one second set based on the area of each first set in the at least one first set; the second set characterizes a first set that matches, in area, the area of the same train traveling on a set traffic route; sending second information to each terminal corresponding to each second set; the second information represents the user information corresponding to other terminals in the second set, and the server performs cluster analysis on the radio frequency fingerprint information, so that the data processing amount is reduced, the data processing efficiency is improved, the user information of the same train can be determined and recommended according to the radio frequency fingerprint information, and accurate user information recommendation can be performed.

In an embodiment, as shown in fig. 7, when the region where each first set in the at least one first set is located is estimated based on the second radio frequency fingerprint information corresponding to each set reference point in the plurality of set reference points, the method includes:

s701: determining a second similarity of second radio frequency fingerprint information corresponding to the first set and each set reference point based on third radio frequency fingerprint information corresponding to the first set; the third radio frequency fingerprint information is the radio frequency fingerprint information corresponding to the central position of the first set.

Here, since the similarity between the first rf fingerprint information in the same first set is very high, in order to reduce the data amount in the data processing process, the location estimation may be performed based on one first rf fingerprint information in the first set, so that the area where the first set is located may be obtained, and it is not necessary to determine the area where the first set is located after performing the location estimation on each first fingerprint information in the first set, so that the data amount required to be processed may be greatly reduced, and in order to more accurately determine the area where the first set is located, the first rf fingerprint information selected for data processing needs to satisfy a certain condition. In practical application, for a cluster obtained by cluster analysis, data at the center of the cluster is usually selected as a representative object of the cluster, in this embodiment, radio frequency fingerprint information corresponding to the center position of the first set is used as third radio frequency fingerprint information, where the third radio frequency fingerprint information is the representative object of the first set, and in practical application, the third radio frequency fingerprint information may be radio frequency fingerprint information closest to the average radio frequency fingerprint information characteristic in the first set, and the radio frequency fingerprint information located in the same region has high similarity or even can be completely consistent, so that similarity calculation is performed on the third radio frequency fingerprint information and second radio frequency fingerprint information corresponding to a set reference point, and the second similarity is determined, which is favorable for determining the region where the first set is located.

S702: and determining the area where the first set is located according to the corresponding position information of the set reference point with the highest second similarity.

Here, the position of the first set may be estimated according to a difference of the second similarity, for example, the lower the second similarity is, the lower the probability that the first set is located in the area where the corresponding set reference point is located is, the higher the second similarity is, the higher the probability that the first set is located in the area where the corresponding set reference point is located is, and in practical application, the position information of the corresponding set reference point when the second similarity is the highest is determined as the area where the first set is located. For example, the second similarity of the third radio frequency fingerprint information to the station of site X is lower than the second similarity of the third radio frequency fingerprint information to the station hall of site X, and it may be determined that the area in which the first set is located is the station hall area of site X.

In the above embodiment, based on the third rf fingerprint information corresponding to the first set, the second similarity of the second rf fingerprint information corresponding to each set reference point is determined; the third radio frequency fingerprint information is the radio frequency fingerprint characteristics corresponding to the central position of the first set; according to the corresponding position information of the set reference point with the highest second similarity, the area where the first set is located is determined, so that the data volume required to be processed in the process of determining the position corresponding to the radio frequency fingerprint can be reduced, the data processing efficiency is improved, users located on the same train can be accurately determined, and high-precision user recommendation information is provided.
