Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In order to solve the problem of how to determine whether to switch from one wireless access point to another wireless access point if the terminal is in a situation of location movement and the like after the mobile terminal initially selects one wireless access point to access in an environment with a plurality of wireless access points, an embodiment of the present disclosure first provides a wireless access point switching method, as shown in fig. 1, the method may include the following steps:
in step S110, a preset application currently running in the mobile terminal is monitored.
The mobile terminal can be a smart phone, a tablet computer, a smart watch and other devices, taking the smart phone which is most commonly used by a user as an example, with the continuous development of the technology, the screen size, the storage space and the like of the smart phone are also larger and larger, and the design of the mobile terminal is more in line with the requirements of the user. At present, a smart phone of a user can be provided with a plurality of applications, and can run the plurality of applications simultaneously, the user can display an interface of the application which needs to be operated on a screen, other running applications run in the background, and the application which needs to be operated can be switched to the screen to be operated continuously according to the needs of the user.
Therefore, it is necessary to detect which application or applications are currently running on the smartphone. Because some application programs can be normally used under the condition that the smart phone is not connected with the network, some application programs can be normally used only by means of networking, and different application programs can be normally used only by means of networking, the network rates required by normal operation can be different. It is necessary to monitor whether some applications are running, such as applications with high usage frequency and/or applications with high network transmission rate.
In step S120, a desired network transmission rate of a preset application currently running is calculated.
When it is monitored that the application programs which are frequently used and require a large network transmission rate are running, the average network transmission rate required by each application program in the application programs in normal running needs to be calculated. The average network transmission rate required by the application program during normal operation may be an average network transmission rate in a certain period of time when the application program is normally used before, such as an average network transmission rate in the last 24 hours, or an average network transmission rate required from the beginning of the application program being used on the mobile terminal to the last time, and the average network transmission rate is taken as the desired network transmission rate.
The calculation of the expected network transmission rate needs to inquire the history record of the application program networking and the like, and the network transmission rate required by the re-operation can be obtained as the expected network transmission rate through a large amount of data statistics and by combining machine learning and the like.
After the expected network transmission rate of each preset application program in the currently running preset application programs is calculated, the expected network transmission rates of each preset application program are added to obtain the expected network transmission rate of the mobile terminal.
In step S130, an actual network transmission rate generated by a current wireless access point to which the mobile terminal is connected is detected.
After the mobile terminal is connected to a wireless access point, the actual network transmission rate generated by the current wireless access point to which the mobile terminal is connected is obtained because the preset application program currently running on the mobile terminal needs to send and receive data. The network transmission rate may include an uplink network transmission rate and a downlink network transmission rate.
The actual network transmission rate generated by the current wireless access point to which the mobile terminal is connected may be the network transmission rate at the current moment, or may be an average network transmission rate in a period from a certain moment to the current moment.
In step S140, it is determined whether the actual network transmission rate is less than the desired network transmission rate.
When the actual network transmission rate is less than the desired network transmission rate, an instruction request for switching from the current wireless access point to another wireless access point is issued to the mobile terminal in step S150.
If the actual network transmission rate of the mobile terminal is less than the expected network transmission rate, it indicates that the actual network transmission rate of the mobile terminal is likely not to meet the network transmission rate required by the currently running preset application program, and it is likely that the preset application program cannot normally receive and transmit data, so that an instruction request for switching from the current wireless access point to another wireless access point needs to be sent to the terminal, so that the mobile terminal can intervene in the other wireless access points to meet the requirement for realizing the network transmission rate.
The wireless access point switching method provided by the embodiment of the disclosure obtains expected network transmission rates required by the application programs in normal operation by monitoring the preset application programs currently operated by the mobile terminal, and when the expected network transmission rate is greater than the actual network transmission rate generated by the connection of the current mobile terminal to the wireless access point, the actual network transmission rate of the current access point is proved to be not meet the requirement of the network transmission rate of the current application program in normal operation, and at this time, a request can be sent to the mobile terminal in time, so that the mobile terminal can be switched to other wireless access points, and the influence on the normal operation of the preset application programs in the terminal due to the verse network transmission rate of the current wireless access point can be avoided as much as possible.
In order to further accurately determine whether the current actual network transmission rate meets the requirement of the preset application program currently running when the actual network transmission rate of the mobile terminal is less than the expected network transmission rate, as a refinement of the method of fig. 1, as shown in fig. 2, the method may further include the following steps:
when the actual network transmission rate is less than the expected network transmission rate, in step S210, timing is started to obtain a first timing duration.
The first timed period may be a period of time such as 5 minutes.
In step S220, a plurality of different types of data abnormal values generated by each preset application during data transmission are respectively calculated among all the preset applications currently running.
The different types of data abnormal values may be data abnormal values obtained according to data that the preset application program does not normally receive and/or transmit during data transmission.
In step S230, it is determined whether the first timed period is greater than the first set period.
When the first timed period is longer than the first set timed period, in step S240, the total data abnormal value of the same type of all the preset applications is calculated.
The total data outliers of the same type for all the preset applications may be the sum of the outliers for each application.
In step S250, it is determined whether the total data abnormal values of each type are each larger than the corresponding set threshold.
When the total data abnormal value of each type is respectively larger than the corresponding set threshold, in step S260, a step of issuing an instruction request for switching from the current wireless access point to another wireless access point to the mobile terminal is performed.
If the total data abnormal value of each type of the preset application program is respectively larger than the corresponding set threshold, it indicates that the current actual network transmission rate cannot meet the requirement of the network normally required by the currently running preset application program, and therefore, an instruction request for switching from the current wireless access point to another wireless access point needs to be sent to the mobile terminal.
In order to accurately and respectively calculate a plurality of different types of data abnormal values generated by each preset application program during the data transmission process, as a refinement of the method of fig. 2, as shown in fig. 3, the step S220 may further include the following steps:
wherein, aiming at each preset application program, the following steps are executed:
in step S221, the number of transmission timeout packets, the number of reception timeout packets, and the number of error packets generated by the preset application during the data transmission process are monitored.
The receiving overtime packet is a data packet which is not responded by the server within the waiting time of the application program, the sending overtime packet is a data packet which is not sent to the server by the application program within the default time, and the error packet is a data packet which is sent/received by the mobile terminal in error when the mobile terminal carries out data transmission with the server. The generation of the transmission timeout packet, the reception timeout packet and the error packet is probably caused by the low network transmission rate at the current time.
In step S222, a priority weighting factor of the preset application program in the preset monitoring list is obtained.
Before the process is performed, a preset monitoring list may be established, where the preset monitoring list may include application software that is frequently used and has a high use frequency and needs to be networked for normal use, and priority weighting coefficients of the application software may be set according to a network transmission rate required when the application software is normally used, for example: the higher the network transmission rate required by the application software in normal use, the larger the priority weighting factor, as an example, as shown in table 1.
TABLE 1
| Application software | Youke | Safari | … | High-speed rail manager | |
| Priority weight coefficient | 90 | 80 | 60 | … | 20 |
In step S223, the number of transmission timeout packets, the number of reception timeout packets, and the number of error packets are respectively calculated with the priority weighting coefficient.
And multiplying the number of the sending overtime packets, the number of the receiving overtime packets and the number of the error packets of the preset application program by the corresponding priority weighting coefficients respectively to obtain the sending overtime value, the receiving overtime value and the error packet value of each preset application program respectively.
Illustratively, for example, the number of transmission timeout packets, the number of reception timeout packets, and the number of error packets of the WeChat currently running in the mobile terminal are respectively 80, 70, and 60, and table 1 is looked up, the priority weighting coefficient of the WeChat is obtained by multiplying the number of WeChat packets, the number of reception timeout packets, and the number of error packets by 80 to obtain a transmission timeout value, a reception timeout value, and an error packet value, and the transmission timeout value, the reception timeout value, and the error packet value of the WeChat are 6400, 5600, and 4800, respectively.
In step S224, the transmission timeout value, the reception timeout value, and the error packet value of the preset application are determined, and the transmission timeout value, the reception timeout value, and the error packet value are taken as three types of data abnormal values.
In order to more accurately monitor the preset application currently running in the mobile terminal, as a refinement of the method of fig. 1, as shown in fig. 4, the step S110 may further include the following steps:
in step S111, all applications currently running in the mobile terminal are monitored.
All applications currently running in the mobile terminal include an application running in the foreground of the mobile terminal and an application running in the background of the mobile terminal.
In step S112, the identification of each application program is acquired.
Since each application has a unique identification to distinguish other applications, the identification may be the name of the application, code, or the like.
In step S113, it is determined whether a corresponding identifier exists in the preset monitoring list for each identifier of the application.
According to the obtained identification marks of each running application program, comparing the identification marks with the identification marks in a preset monitoring list one by one, and determining whether the preset monitoring list contains the identification marks of the applications.
The preset monitoring list comprises identification marks of preset application programs.
When the corresponding identification exists in the preset monitoring list, in step S114, the application program having the corresponding identification in the preset monitoring list is determined as the preset application program.
In order to accurately calculate the expected network transmission rate of the preset application currently running, as a refinement of the method of fig. 1, as shown in fig. 5, step S120 may include the steps of:
in step S121, the historical network transmission rate of the preset application program is acquired.
The historical network transmission rate of the preset application program may be the historical network transmission rate of the preset application program in a certain period of time, or may be all the historical network transmission rates of the preset application program.
According to practical situations, if the preset application is used for a long time and is used frequently, the historical network transmission rate of the preset application may be large, and the historical network transmission rate of the latest representative period of time may be selected.
In step S122, an average network transmission rate of the currently running preset application program in the preset time period is calculated according to the historical network transmission rate.
For example, the average network transmission rate of a preset application over the last 24 hours may be calculated.
In step S123, the average network transmission rate is determined to be the desired network transmission rate.
As a further optimization of the method of fig. 1, as shown in fig. 6, in order to solve the problem that after the mobile terminal connects to another wireless access point from the current wireless access point, when the mobile terminal detects that a newly accessed wireless access point reconnects to the previous wireless access point due to the condition not being met in the above step, the mobile terminal is caused to switch back and forth between the wireless access points that do not meet the condition, the power consumption of the mobile terminal is increased, and the network connection of the mobile terminal is unstable, the method may further include the following steps:
in step S610, it is detected whether the mobile terminal is handed over to another wireless access point.
The method and the device can monitor the wireless access point currently accessed by the mobile terminal in real time, for example, the name of the wireless access point currently accessed by the mobile terminal is obtained, and when the name of the wireless access point accessed by the mobile terminal is monitored to be changed, the change of the wireless access point accessed by the mobile terminal can be confirmed.
When it is detected that the mobile terminal is handed over to another wireless access point, in step S620, the last wireless access point is added to the prohibited access list, and timing is started to obtain a second timing duration.
Therefore, in order to prevent the problem that the mobile terminal is switched back and forth between two wireless access points when the mobile terminal is switched from one wireless access point to another wireless access point and then detects that another wireless access point does not meet the requirement, the mobile terminal is switched to the previous wireless access point, and the previous wireless access point is added into the access prohibition list, and the access to the previous wireless access point is prohibited for a period of time.
In step S630, it is determined whether the second timed period is greater than the second set period.
The second set time period may be preset, for example, 2 hours.
When the second timer duration is longer than the second set timer duration, in step S640, the last wireless access point is removed from the prohibited access list.
The wireless access point switching method provided by the embodiment of the disclosure obtains expected network transmission rates required by the application programs in normal operation by monitoring the preset application programs currently operated by the mobile terminal, and when the expected network transmission rate is greater than the actual network transmission rate generated by the connection of the current mobile terminal to the wireless access point, the actual network transmission rate of the current access point is proved to be not meet the requirement of the network transmission rate of the current application program in normal operation, and at this time, a request can be sent to the mobile terminal in time, so that the mobile terminal can be switched to other wireless access points, and the influence on the normal operation of the preset application programs in the terminal due to the verse network transmission rate of the current wireless access point can be avoided as much as possible.
And when the expected network transmission rate is less than the actual network transmission rate generated by the connection of the current mobile terminal to the wireless access point, in order to further accurately judge whether the current wireless access point meets the actual network rate requirement of the mobile terminal, whether abnormal values such as a transmission timeout value, a reception timeout value, a packet error value and the like of a preset application program which is currently running meet conditions is also detected, and then whether the mobile terminal needs to switch the wireless access point is judged according to the conditions.
