In the system, a plurality of intervals can be preset for each link quality auxiliary parameter, each interval corresponds to one score, and the score corresponding to each interval can be flexibly set by a person skilled in the art. Taking the RSRQ as an example of the link quality auxiliary parameter, after the RSRQ of the link is monitored, comparing the RSRQ value with a plurality of intervals preset for the RSRQ in the system, determining the interval to which the monitored RSRQ value belongs, and determining the score corresponding to the interval as a correction value. Similarly, another correction value may be determined based on the monitored RSSI. And under the condition that the link quality auxiliary parameters simultaneously comprise RSRQ and RSSI, correcting the first score corresponding to the link according to the two correction values to obtain a second score corresponding to the link.
And secondly, correcting the first score corresponding to the link by taking the score corresponding to the interval as a correction value to obtain a second score corresponding to the link.

In an optional embodiment, before monitoring the reference signal received power of the link with each cell and the link quality auxiliary parameter, the following steps may be further included:
the method comprises the following steps: and receiving a second input of the user in the network setting interface.
Network setup interface schematic as shown in fig. 2, a second input may turn on the operation of the optimized network switch, for example: the manual sliding as shown in fig. 2 optimizes the sliding operation of the network switch.
Step two: and responding to the second input, and displaying a network optimization mode option.

Step four: and determining a target network optimization mode in response to the third input.
And after the target network optimization mode is determined, the system is switched to a corresponding target network optimization mode.
In this optional embodiment, the user may flexibly set a network optimization mode according to actual needs to meet personalized needs of the user.
In an optional embodiment, the step of determining the target cell to be handed over according to the second score corresponding to each link includes the following substeps:
the first substep: and under the condition of being set to a manual optimization network mode, displaying the first identification of each cell, the second identification of the link corresponding to the cell and the second score corresponding to the link, and the corresponding relation among the first identification, the second identification and the second score.
In the case of being set to the manual optimization network mode, the second scores corresponding to the cells may be displayed in a list form, an exemplary display manner is as shown in the first interface diagram shown in fig. 3, the total number of the searched cells is 3, the first identifier of the cell is represented by its corresponding base station identifier, such as cell1, cell2, and cell3, and the second identifier of the link corresponding to the cell may be represented as Sore _ Link11、Sore_Link21 and Sore _ Link31, Link Sore _ Link11、Sore_Link21 and Sore _ LinkThe second scores of 31 correspond to scores of 81, 80 and 83, respectively. The three cells are sorted in the cell list according to the sequence of the second scores from high to low, so that the user can conveniently check the three cells.
And a second substep: a first user input of a target cell identity is received.
The first input is used to select a target cell, and as shown in fig. 3, the first input may be a touch operation on a column corresponding to the target cell in the cell list.
In the third step: and in response to the first input, determining the cell corresponding to the target cell identification as the target cell.
After a user manually selects a target cell, the system is switched to the target cell; when the network provided by the target cell does not meet the requirement of the user, the user can return to the interface again to reselect the target cell. The network provided by the target cell may not meet the user requirement due to inaccurate evaluation of the second score corresponding to the link or occurrence of an emergency in the target cell.
The optional way of manually selecting the target cell is to finally select the target cell to meet the actual requirements of the user.
Optionally, in an embodiment, after the first score corresponding to each link is corrected according to the link quality auxiliary parameter corresponding to each link to obtain the second score corresponding to each link, the method may further include the following steps:
the method comprises the following steps: for each cell, a historical service score for the cell is obtained.
The historical service score for an individual cell may be generated as follows: under the condition that each electronic device is accessed into the cell to carry out network communication, each electronic device uploads communication parameters of the cell to a cloud end; the cloud carries out scoring for the cell according to the received communication parameters of the cell, and generates a historical service score of the cell, wherein the communication parameters comprise: outage probability and maximum transmission rate of a cell.
One feasible way is that, in the historical use process, when the electronic equipment is accessed into a certain cell for network communication, the electronic equipment records and automatically uploads the communication parameters of the accessed cell to the cloud, the cloud counts the feedback of the communication parameters of the cell by each electronic equipment, and the counted feedback of the communication parameters is used for scoring the cell to generate the historical service score of the cell.
The cloud end is at preset time intervals or according to fixed times such as 8 morning each day: 00 issues a list of historical service scores for each cell that can connect to the electronic device. Therefore, when the electronic device corrects the second score of the link corresponding to the cell in the cell switching process, the electronic device may obtain the corresponding historical service score from the received historical service score list of each cell. Specifically, the electronic device may search whether the historical service score list includes the historical service score of the searched cell, and if so, obtain a corresponding historical service score, for example, the historical service score of the cell m may be recorded as Sore _ Cm; if not, the historical service score of the search cell may be marked as 0.
The cloud end updates the historical service score of the cell regularly, for example, the cutoff probability of the cell A is counted to be large on Saturday, and then the historical service score of the time period is reduced; correspondingly, when the electronic device is in the same time period, after the historical service score of the cell a in the time period is obtained and the second score of the link corresponding to the cell a is corrected, the probability that the electronic device is switched from the current service cell to the cell a is small.
Step two: and correcting the second score corresponding to the link between the cells according to the historical service score to obtain a third score corresponding to the link.
One possible correction is to determine the sum of the historical service score and the second score as a third score corresponding to the link. Of course, the method is not limited to the above summation correction method, and a person skilled in the art may flexibly set a method for correcting the second score corresponding to the link according to the historical service score, which is not specifically limited in the embodiment of the present application.
And correspondingly, the system determines the target cell to be switched according to the third scores corresponding to the links.
In the automatic network optimization mode, the system can automatically select the cell corresponding to the link with the highest third score as the target cell, and switch from the current serving cell to the target cell. In the manual network optimization mode, aiming at each cell, the system displays the corresponding relation of the first identifier of the cell, the second identifier of the link, the historical service score, the second score and the third score, and a user can flexibly select a target cell according to actual requirements.
An exemplary display manner is as shown in a second interface schematic diagram shown in fig. 4, where the total number of searched cells is 3, the first identifier of a cell is represented by corresponding base station identifiers such as cell1, cell2, and cell3, and the second identifier of a link corresponding to the cell can be represented as Sore _ Link11、Sore_Link21. And Sore _ Link31, the second scores corresponding to the three links are 81, 80 and 82, the historical service scores corresponding to the cell1, the cell2 and the cell3 are 1, -2 and 3, the third scores corresponding to the cell1, the cell2 and the cell3 are 82, 78 and 85, the three cells are sorted in the cell list according to the sequence of the third scores from high to low, and the user can conveniently view the three cells. As shown in fig. 4, the user may perform a first input on the row corresponding to the target cell in the cell list to select the target cell.
In the optional embodiment, the cells are scored by combining the RSRP, the link quality auxiliary parameters and the history conditions of the provided network of each cell, the obtained score is more accurate and reliable, and the cells with poor networks can be prevented from being switched to.
In an optional embodiment, after the second score corresponding to the link is corrected according to the historical service score to obtain a third score corresponding to the link, the method may further include the following steps:
the method comprises the following steps: for each cell, a type to which the cell belongs is determined.
Wherein the types of the cells include: the system comprises a service cell and adjacent cells, wherein the service cell is a cell where the electronic equipment is located currently, namely a cell corresponding to a currently connected network, and the adjacent cells are detected cells which can be switched by the electronic equipment.
The information of the serving cell and the adjacent cell has asymmetry, and the serving cell and the adjacent cell can monitor different parameters and can additionally monitor parameters such as signal to interference plus noise ratio and bandwidth of a link. Therefore, in this optional embodiment, it is necessary to determine the type of the cell, and correct the third fractional value of the serving cell in combination with the parameters, such as the signal to interference plus noise ratio and the bandwidth, of the link that can be additionally monitored.
Step two: and monitoring a preset parameter of a link between the cell and the serving cell under the condition that the cell is the serving cell.
Wherein the preset parameter comprises at least one of the following parameters: signal to interference plus noise ratio and bandwidth.
Step three: and correcting the third score corresponding to the link between the serving cells according to the preset parameters to obtain a fourth score corresponding to the link.
And scoring the serving cell based on the preset parameters of the serving cell to obtain the characteristic correction value of the serving cell. When the third score of the serving cell is corrected according to the serving cell characteristic correction value, the scored serving cell characteristic correction value and the third score may be summed to obtain a fourth score. Of course, the rule for correcting the third partition value based on the serving cell characteristic correction value may be set by a person skilled in the art according to actual needs, and this optional embodiment is not particularly limited thereto.
The serving cell is scored based on the preset parameters of the serving cell, and the manner of obtaining the serving cell characteristic correction value may be as follows:
in the system, a plurality of intervals can be preset for each preset parameter, each interval corresponds to one score, and the score corresponding to each interval can be flexibly set by a person skilled in the art. Taking the preset parameter of the signal to interference plus noise ratio as an example, after the signal to interference plus noise ratio of the link is monitored, the signal to interference plus noise ratio is compared with a plurality of intervals preset for the signal to interference plus noise ratio in the system, the interval to which the monitored signal to interference plus noise ratio belongs is determined, and the score corresponding to the interval is determined as the serving cell characteristic correction value. Similarly, the serving cell characteristic correction value corresponding to the bandwidth may be determined by referring to the above method. And under the condition that the preset parameters simultaneously comprise the signal-to-interference-plus-noise ratio and the bandwidth, correcting the third score corresponding to the link according to the two serving cell characteristic correction values to obtain a fourth score corresponding to the link.
Step four: and under the condition that the cell is the adjacent cell, determining the third score corresponding to the link between the adjacent cells as the fourth score corresponding to the link.
Correspondingly, the system determines the target cell to be switched according to the fourth scores corresponding to the links.
An exemplary display manner is as shown in a third interface schematic diagram shown in fig. 5, where the total number of searched cells is 3, the first identifier of a cell is represented by corresponding base station identifiers such as cell1, cell2, and cell3, and the second identifier of a link corresponding to the cell can be represented as Sore _ Link11、Sore_Link21 and Sore _ Link31, the second scores corresponding to the three links are 81, 80 and 82, the historical service scores corresponding to the cell1, the cell2 and the cell3 are 1, -2 and 3, respectively, the cell3 is a serving cell, the serving cell characteristic correction value Sore _ S is-5, after the second scores corresponding to the links corresponding to the cells are corrected through the historical service scores and the serving cell characteristic correction values, the fourth scores corresponding to the cells 1, the cell2 and the cell3 are 82, 78 and 80, respectively, and the three cells are sorted in the cell list according to the sequence of the third scores from high to low, so that the user can conveniently check the three cells. As shown in fig. 5, the user may perform a first input on the row corresponding to the target cell in the cell list to select the target cell.
