Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the method of the present application are provided.

Fig. 3 is a flowchart of an embodiment of an antenna switching method provided by the present application. The method of the embodiment is applied to the mobile terminal, and once the method is triggered by a user, the flow in the embodiment is automatically operated through the terminal, wherein each step can be sequentially performed according to the sequence as in the flow chart when the method is operated, or a plurality of steps can be simultaneously performed according to the actual situation, and the method is not limited herein. When the antenna switching mode provided by the application is implemented, the antenna switching mode can be realized by the following steps:

step S310, determining the current application scene of the mobile terminal;

step S320, obtaining a scene main antenna corresponding to the current application scene;

step S330, obtaining a current antenna used by the mobile terminal;

And step S340, when the current antenna is different from the main scene antenna, controlling to switch the current antenna used by the mobile terminal into the main scene antenna.

Through the embodiment, the technical problem of the best signal receiving capability can be maintained in any scene, the corresponding main antenna in different application scenes can be dynamically adjusted and updated according to the use habit of a user, and the communication signals received by the main antenna are utilized, so that the signal quality received by the mobile terminal is improved, and the communication experience of the user is improved.

The above-described scheme will be specifically described below.

In step S310, a current application scenario of the mobile terminal is determined. The application scenario may refer to a physical environment in which the mobile terminal is located, for example, a conference room, a home, a mall, etc., and the application environment may refer to a service function in which the mobile terminal is currently running or used, for example, a communication service, a internet access service, or a near field communication service, etc.

Specifically, step S310 may be implemented as follows:

step S3101, determining each scene parameter corresponding to each application scene acquired by the mobile terminal;

step S3102, current parameter values of all scene parameters are obtained in real time or at regular time;

In step S3103, when there is a change between the current parameter value of the specific application scene and the parameter value of the previous time of the specific application scene, the specific application scene is determined to be the current application scene.

In step S3101, the application scene is determined according to specific scene factors, where in this embodiment, the application scene includes but is not limited to: geographic location, call state, service data state, network access technology, working frequency band and working frequency point. In other embodiments, the scenario factors of the application scenario may also be determined according to user definition. And reading each scene parameter item corresponding to each application scene, which is stored in the memory in advance.

In step S3102, in the present embodiment, the detection frequency may be preset, and the current parameter value corresponding to each scene parameter item may be triggered and acquired every specific time interval. In other embodiments, the current parameter value corresponding to each scene parameter item may be detected in real time. In an alternative embodiment, the current parameter values corresponding to the scene parameter items may also be obtained according to the triggering of the operation of the user.

In step S3103, the parameter value at the previous time may be a time point adjacent to the current detection time point, for example, if the current parameter value is obtained according to the operation trigger of the user, the previous time point is the time point of the previous user input trigger operation. The change threshold is predetermined, in this embodiment, a uniform change threshold is used, and in other embodiments, a corresponding change threshold is determined according to different scene factors. By the method, the scene factors which effectively change can be accurately determined, and the current application scene of the mobile terminal can be accurately determined. Further, in order to prevent confusion in determining a subsequent determined scene main antenna caused by existence of effectively changed scene factors, the priority corresponding to each application scene is predetermined, and the method further includes: when the current parameter value of at least two specific application scenes and the parameter value at the previous moment change, acquiring priorities corresponding to the at least two specific application scenes respectively; and determining the specific application scene with high priority as the current application scene.

Through the embodiment, the current application scene of the mobile terminal can be effectively and rapidly determined, and the occurrence of misjudgment can be effectively reduced in a mode of setting the priority, so that the computing efficiency and the user experience are improved.

In step S320, a scene main antenna corresponding to the current application scene is acquired. The mobile terminal is configured with at least two antennas, the received signal quality of different antennas in the same application scene is not the same, and if the corresponding service function is realized by using the signal received by the antenna with poor received signal quality, the operation experience of the user can be influenced. And recording the antenna with the best received signal quality in different application scenes in the history use process of the mobile terminal, and taking the antenna as a main antenna in the application scenes. In this embodiment, the corresponding relation between the application scene and the scene main antenna may be determined by a preset manner. In other embodiments, the scene main antenna corresponding to the application scene may be dynamically adjusted by an autonomous learning manner.

Specifically, the histories of the scene main antennas used in each application scene are counted, and the scene main antenna corresponding to the current application scene is determined according to the histories of the scene main antennas. The history record is recorded for the used main antenna of the scene in different application scenes, because the signal quality received in the same application scene is not the best of the signal quality received in all antennas even though the antennas are the same.

According to the embodiment, the history records of the main antennas corresponding to the application scene are counted, and the main antenna which is likely to receive the signal with the best quality in the current application scene is calculated according to the history records through a preset algorithm. And along with the continuous increase and perfection of data in the history record, the calculation precision can be higher, so that the corresponding accuracy of the application scene and the scene main antenna is continuously improved, and the mobile terminal can be ensured to receive signals with the best quality in different application scenes to the greatest extent.

Further, the step of counting the history of the scene main antenna used in each application scene may include the steps of:

step S3201, obtaining at least two signal qualities received by the at least two antennas in a specific application scene;

step S3202, comparing the strength relation of the at least two signal qualities;

step S3203, determining that the antenna with strong received signal quality is a scene main antenna corresponding to the application scene, and establishing a history record of the scene main antenna corresponding to the application scene.

Specifically, as described in the text, the mobile terminal is configured with at least two antennas, and after determining the current application scenario of the mobile terminal, the mobile terminal triggers and reads signal instructions received by different antennas. In the scheme of the statistics history record, the specific application scenario may be that the mobile terminal automatically determines the current application scenario according to the foregoing manner, or may provide the current application scenario to the user to select an operation interface, and receive a corresponding operation instruction through the operation interface to determine the application scenario for the statistics history record. In this embodiment, the process of counting the main antennas of the scene used in each application scene may be running in the background, that is, without affecting the selection of the main antennas of the current application scene. The signal quality can be determined by related parameters such as signal strength, signal attenuation, signal fluctuation, amplitude and the like, and the method is not particularly limited. After the signal quality of each antenna in the current application scene is obtained, the signal quality intensity received by each antenna is further judged. And determining the antenna with strong signal quality as the scene main antenna corresponding to the current application scene, and establishing a history record of the current application scene corresponding to the determined scene main antenna. In a specific recording process, different identifications of different antennas are preset, and corresponding records of the application scene and the identifications of the scene main antennas are established in a history record.

In other embodiments, the history of the scene main antenna used in each application scene is also counted, and the record information generated in the following case is included: when the signal quality received by the scene main antenna corresponding to the changed application scene is weaker than the signal quality of the main antenna currently working (namely, the scene main antenna corresponding to the scene before the change), a history record of the scene main antenna corresponding to the changed application scene is established by taking the main antenna currently working as the scene main antenna corresponding to the changed application scene. More specific steps will be described below.

Further, the step of determining the scene main antenna corresponding to the current application scene according to the history record of the scene main antenna includes:

step S3204, a K+1 dimension vector is established according to the scene information and the scene main antenna identification;

step S3205, a vector set formed by N K+1-dimensional vectors is established according to the history record of the scene main antenna;

step S3206, determining a current K-dimensional vector of a current application scene;

step S3207, obtaining a K+1-dimensional vector with the shortest distance between the current K-dimensional vector and the vector set according to a proximity algorithm;

Step S3208, determining the scene main antenna corresponding to the shortest k+1 dimension vector as the scene main antenna corresponding to the current application scene.

According to the embodiment, each time the application scene is changed, the scene main antenna which is most likely to be the corresponding scene of the current application scene can be obtained dynamically according to the history record formed by the history corresponding relation between the application scene and the scene main antenna, and further the working signal is received through the scene main antenna, so that the technical effect of keeping the best signal receiving capability in any scene is achieved.

Specifically, regarding step S3204, the scenario information and the scenario main antenna are subjected to vectorization processing, in this embodiment, the scenario information is determined by M scenario factors, and the K-dimensional vector is obtained by vectorizing the factors constituting the scenario, where K may be the same as M or different from M, and specifically depends on the calculation requirement. And adding the identification corresponding to the scene main antenna selected at the moment to obtain the k+1-dimensional vector.

Regarding step S3205, by adopting the vectorization processing as in step 3204 for each history record, a vector set composed of a plurality of k+1-dimensional vectors corresponding to a plurality of history records is obtained, which is also equivalent to a sample data set, for calculating a scene main antenna corresponding to the current application scene based on the sample data set.

Regarding steps S3206 to S3208, after determining the current application scenario, the current K-dimensional vector is obtained by vectorizing the scenario factors corresponding to the application scenario. The distance between the current K-dimensional vector and each vector in the vector set formed by the history is calculated by adopting a proximity algorithm, wherein the calculation principle of the proximity algorithm is that if most of K nearest neighbor samples in a feature space belong to a certain class, the samples also belong to the class and have the characteristics of the samples on the class. The method only determines the category to which the sample to be classified belongs according to the category of one or more samples which are nearest to each other in determining the classification decision. In this embodiment, the distribution situation of each k+1-dimensional vector is learned in advance in the vector set, and the k+1-dimensional vector nearest to the current K-dimensional vector is obtained through the proximity algorithm, so that the situation of the application scene corresponding to the current K-dimensional vector is considered to be closest to the situation of the application scene corresponding to the k+1-dimensional vector nearest to the current K-dimensional vector, and further, the scene main antenna corresponding to the shortest k+1-dimensional vector is determined to be the scene main antenna corresponding to the current application scene.

In step S330, a current antenna used by the mobile terminal is acquired.

The current antenna is a scene main antenna determined by the application scene corresponding to the current antenna before the scene change.

In step S340, when the current antenna is different from the main scene antenna, the current antenna used by the mobile terminal is controlled to be switched to the main scene antenna.

Specifically, by comparing the identification of the current antenna with the identification of the main antenna of the scene, it is determined whether or not the antennas are the same. Because the same scene main antenna exists in different application scenes, if the identification of the current antenna is determined to be the same as the identification of the scene main antenna, the processor does not need to control the antenna switching operation once, and the occurrence of signal interruption is further reduced.

Further, as described above, since the application scenario and the corresponding scenario main antenna are not performed by fixing the corresponding setting mode, but the corresponding scenario main antenna is obtained by dynamically calculating the history record each time, this means that the scenario main antenna calculated each time is not the antenna with the best signal instruction in the current application scenario, in order to increase the number of samples of the history record, and the current application scenario may use the signal with the best quality, in this embodiment, after the scenario main antenna is obtained by calculating, the method further includes the following steps:

Step S3401, obtaining second signal quality received by the main scene line day in the current application scene;

step S3402, when the second signal quality is higher than the first signal quality, establishing a history record of the current application scene corresponding to the scene main antenna;

step S3403, when the first signal quality is higher than the second signal quality, establishing a history of the main scene antenna taking the current antenna as the current application scene.

Specifically, a first signal quality acquired by a current antenna (namely, a scene main antenna determined by an application scene corresponding to a scene change), and a second signal quality received by the scene main antenna calculated by a proximity algorithm are acquired, and an antenna identifier corresponding to a signal with the best received signal quality in the current application scene is determined by comparing the first signal quality with the second signal quality.

The above steps may occur after step S340, i.e., the system has already controlled to complete the switching of the antennas, or may occur before step S340, i.e., the system determines only the scene main antenna corresponding to the current application scene. Therefore, in this embodiment, when it is determined that the second signal quality is higher than the first signal quality, it is determined to control switching of the current antenna used by the mobile terminal to the scene main antenna, and a history record corresponding to the current application scene to the scene main antenna is created. In other embodiments, when it is determined that the second signal quality is higher than the first signal quality, only the history record of establishing a current application scenario corresponding to the scenario main antenna is triggered. When the first signal quality is higher than the second signal quality, it is stated that the calculated scene main antenna is not the optimal antenna of the application scene at this time, in this embodiment, the antenna operating in the application scene is controlled to be switched from the scene main antenna back to the current antenna, and a history of the scene main antenna using the current antenna as the current application scene is established.

Through the embodiment, the current application scene and the identification of the scene main antenna are stored in the history record every time, so that the history record is gradually enriched along with the increase of the use time of a user, and the accuracy of selecting the scene main antenna is improved.
