Referring to fig. 1, a flowchart illustrating steps of a serving cell switching method provided in an embodiment of the present application is shown, where the serving cell switching method may be applied to an electronic device, and as shown in fig. 1, the serving cell switching method may specifically include the following steps:
step 101: and acquiring an initial neighbor cell having a neighbor relation with a target serving cell accessed by the main card under the condition that the electronic equipment is dual-pass electronic equipment and the main card is in a service state.
The embodiment of the application can be applied to a scene that when a main card of bi-pass electronic equipment is in a service state, performance measurement of a neighbor cell is carried out based on an auxiliary card so as to select a cell with optimal performance for the main card.
The bi-pass electronic equipment refers to equipment which supports dual-card service and can receive and transmit service data by both cards.
The service state refers to a state of service data processing.
The target serving cell refers to a cell to which the main card is currently accessed, for example, the serving cell may include a cell a, a cell b, and a cell c, and when the cell to which the main card in the current mobile phone is accessed is the cell b, the cell b is regarded as the target serving cell; and when the cell accessed by the main card in the current mobile phone is the cell c, the cell c is regarded as a target serving cell and the like.
The initial neighbor cell refers to a serving cell having a neighbor relation with the target serving cell.

It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation to the embodiments.
When the electronic device is a dual-channel electronic device and the main card is in a service state, an initial neighboring cell having a neighboring relationship with a target serving cell to which the main card is accessed may be obtained, specifically, a base station corresponding to the target serving cell records each serving cell and serving cells having a neighboring relationship with each serving cell, and after obtaining the target serving cell, the initial neighboring cell having a neighboring relationship with the target serving cell may be obtained by the base station.
After acquiring the initial neighbor cell having the neighbor cell relationship with the target serving cell accessed by the main card, step 102 is executed.
Step 102: and utilizing a secondary card to measure the cell signal quality of the initial neighbor cell, and deleting the neighbor cells which do not meet the preset signal quality condition in the initial neighbor cell to obtain the target neighbor cell.
The target neighbor cell refers to remaining neighbor cells after deleting neighbor cells whose signal quality does not satisfy the preset signal quality condition in the initial neighbor cell, for example, the initial neighbor cells include cell 1, cell 2, cell 3, cell 4, and cell 5, and after deleting cell 1 and cell 4 which do not satisfy the condition in these cells, the remaining initial neighbor cells are cell 2, cell 3, and cell 5, and then cell 2, cell 3, and cell 5 are regarded as the target neighbor cells.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation to the embodiments.
The preset signal quality condition refers to a cell signal quality condition preset by a service person for determining a neighboring cell, and in this example, the preset signal quality condition may be a signal quality threshold condition, such as a reference signal received power threshold or a reference signal received quality threshold.
After the initial neighbor cell having a neighbor relation with the target serving cell accessed by the main card is obtained, the secondary card can be used for measuring the cell signal quality of the initial neighbor cell, and the neighbor cells which do not meet the preset signal quality condition in the initial neighbor cell are deleted according to the measurement result, so that the target neighbor cell can be obtained.
After the target neighbor cell is acquired, step 103 is executed.

In this example, the data card scene information may be obtained from the data card scene information of the main card through an application program currently running on the electronic device, for example, when the electronic device is currently playing a live game, because the live game has a high requirement on delay, at this time, it may be determined that the data card scene information corresponding to the main card is delay-sensitive scene information; or, when the electronic device is currently playing a video, because a higher throughput is required when playing the video, smooth playing of the video is ensured, at this time, it may be determined that the data card scene information of the main card is throughput-sensitive scene information and the like.
After the target neighbor cell is obtained, an access neighbor cell meeting the access condition can be screened out from the target neighbor cell according to the data card scene information of the main card, at the moment, the main card can be controlled to be accessed to the access neighbor cell, and then the switching from the target service cell to the access neighbor cell by the main card is completed.
According to the embodiment of the application, when the main card is in the service state, the auxiliary card is used for monitoring and evaluating the quality of the adjacent cell, so that the service continuity of the data card is ensured, more comprehensive and perfect high-quality alternative cells can be provided for the data card, and the cell networking capability of the terminal in the service state is enhanced.
In this embodiment, the process of screening the target neighbor cell according to the preset signal quality condition may be described in detail with reference to the following specific implementation manner.
In a specific implementation manner of the present application, the step 102 may include:
substep A1: and measuring the cell signal quality of the initial adjacent cell by using the secondary card to obtain a cell signal quality parameter corresponding to the initial adjacent cell.
In this embodiment, the cell Signal Quality parameter may include any one of Reference Signal Received Power (RSRP) and Reference Signal Receiving Quality (RSRQ), and specifically, may be selected according to a service requirement, which is not limited in this embodiment.
After the secondary card is used to measure the cell signal quality of the initial neighboring cell, the cell signal quality parameter corresponding to the initial neighboring cell can be obtained.
After obtaining the cell signal quality parameters corresponding to the initial neighbor cell, sub-step a2 is performed.
Substep A2: and determining a signal quality threshold according to the cell signal quality parameter of the target service cell.
The signal quality threshold is a threshold calculated according to a cell signal quality parameter of the target serving cell.
In this example, a cell signal quality parameter of the target serving cell may be obtained to determine the signal quality threshold, and specifically, the detailed description may be made in conjunction with the following specific implementation manner.

substep B1: acquiring a target cell signal quality parameter of the target serving cell;
substep B2: and generating the signal quality threshold according to the target cell signal quality parameter and the offset value.
In this embodiment, the target cell signal quality parameter refers to a signal quality parameter of the target serving cell.
The offset value refers to a value preset empirically by a service person.
In this example, first, a target cell signal quality parameter of the target serving cell may be obtained, and then, a signal quality threshold may be calculated by combining the target cell signal quality parameter and an offset value, for example, the cell signal quality parameter of the target serving cell is RSRPser, and the signal quality threshold may be calculated by using the offset value, that is, meaRSRP is RSRPser ± threhsrp, where the ramesrp is the signal quality threshold, the threhsrp is the offset value, and the threhsrp may be obtained by a service person according to experience, and a specific value of the threhsrp is not limited in this embodiment.
Of course, in this embodiment, the signal quality threshold may also be a threshold preset by a service person according to experience, and a specific value of the signal quality threshold may be determined according to a service requirement, which is not limited in this embodiment.
After determining the signal quality threshold based on the cell signal quality parameter of the target serving cell, sub-step a3 is performed.
Substep A3: and deleting the initial neighbor cell with the cell signal quality parameter less than or equal to the signal quality threshold value in the initial neighbor cell to obtain the target neighbor cell.
After obtaining the cell signal quality parameter and the signal quality threshold of the initial neighboring cell, the initial neighboring cell in which the cell signal quality parameter is less than or equal to the signal quality threshold in the initial neighboring cell may be deleted, and the remaining initial neighboring cells may be used as target neighboring cells, for example, the initial neighboring cell includes a cell a, a cell b, and a cell c, and the initial neighboring cell in which the cell signal quality parameter is less than or equal to the signal quality threshold in the initial neighboring cell is a cell c, at this time, the cell c in the initial neighboring cell may be deleted, and the remaining cell a and the cell b may be used as target neighboring cells.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation to the embodiments.
According to the embodiment of the application, the adjacent cell with poor signals in the initial adjacent cell can be deleted by setting the signal quality threshold, so that the calculated amount of a system can be reduced when the cell accessed by the main card is calculated subsequently, and the utilization rate of a system memory is improved.
In this embodiment, the process of acquiring the primary card access cell may be described in detail as follows in combination with the delay sensitive scenario information and the throughput sensitive scenario information.
In another specific implementation manner of the present application, the step 103 may include:
substep C1: and acquiring a first time delay corresponding to the target service cell under the condition that the data card scene information is time delay sensitive scene information.
In this embodiment, the delay-sensitive scene information refers to scene information that is sensitive to signal delay, such as a real-time game played by an electronic device, and at this time, a scene in which the main card is located may be regarded as the delay-sensitive scene information.
The first delay refers to the delay caused by the target serving cell providing service.
Under the condition that the data card scene information of the main card is the delay sensitive scene information, the first delay corresponding to the target service cell can be obtained.
Substep C2: and acquiring a second time delay corresponding to the target neighbor cell.
The second delay refers to the delay caused by the service provided by the target neighbor cell.
After the target neighboring cell is obtained, a second time delay corresponding to the target neighboring cell may be obtained.
After the first time delay and the second time delay are obtained, sub-step C3 is performed.
Substep C3: and acquiring a first adjacent cell of which the second time delay is lower than the first time delay in the target adjacent cell.
The first neighbor cell refers to a neighbor cell having a second delay lower than the first delay in the target neighbor cell.
After the first time delay corresponding to the target serving cell and the second time delay corresponding to the target neighboring cell are obtained, the neighboring cell with the second time delay lower than the first time delay may be screened from the target neighboring cell, and the neighboring cell with the second time delay lower than the first time delay obtained by screening is regarded as the first neighboring cell.
After the first neighbor cell is acquired, sub-step C4 is performed, or sub-step C5 is performed.
Substep C4: and taking the first neighbor cell as the access neighbor cell under the condition that the first neighbor cell is one neighbor cell.
Substep C5: and under the condition that the first adjacent cell is at least two adjacent cells, acquiring a first adjacent cell with the lowest time delay in the first adjacent cell, and taking the first adjacent cell with the lowest time delay as the access adjacent cell.
After the first neighboring cell is acquired, the number of acquired cells of the first neighboring cell may be determined, and in a case where the first neighboring cell is one neighboring cell, the first neighboring cell may be used as an access neighboring cell.
And when the first neighboring cell is at least two neighboring cells, the first neighboring cell with the lowest time delay in the first neighboring cell may be acquired, and the first neighboring cell with the lowest time delay is used as the access neighboring cell.
According to the embodiment of the application, under the condition that the main card is in the time delay sensitive scene information, the adjacent cell with the time delay lower than that of the target service cell can be obtained to serve as the access cell of the main card, so that the time delay of data processing can be reduced, and the performance of data processing is improved.
In this embodiment, the following detailed description may be performed on the process of acquiring the primary card access cell in combination with the throughput sensitive scenario information.
In another specific implementation manner of the present application, the step 103 may include:
substep D1: and under the condition that the data card scene information is throughput sensitive scene information, acquiring first throughput corresponding to the target service cell.
In the present embodiment, the throughput refers to the number of successfully transmitted data per unit time of the electronic device.
The throughput-sensitive scene information is scene information that has a high requirement on the amount of data transmitted per unit time, for example, when a user watches a video using an electronic device, the user needs high throughput, and in this case, a scene where the user watches the video is regarded as the throughput-sensitive scene information.
The first throughput refers to the amount of data that the electronic device can successfully transmit per unit time when the target serving cell provides service.
Under the condition that the data card scene is the throughput sensitive scene information, the first throughput corresponding to the target service cell can be obtained.
Substep D2: and acquiring a second throughput corresponding to the target neighbor cell.
The second throughput refers to the amount of data that the electronic device can successfully transmit per unit time when the target neighbor cell provides service.
After the target neighbor cell is acquired, a second throughput corresponding to the target neighbor cell may be acquired.
After the first throughput and the second throughput are obtained, sub-step D3 is performed.
Substep D3: and acquiring a second adjacent cell of which the second throughput is greater than the first throughput in the target adjacent cell.
The second neighbor cell refers to a neighbor cell of the target neighbor cell having a second throughput greater than the first throughput.
After the first throughput corresponding to the target serving cell and the second throughput corresponding to the target neighbor cell are obtained, a second neighbor cell with the second throughput greater than the first throughput may be screened from the target neighbor cell according to the first throughput and the second throughput.
After the second neighbor cell is acquired, sub-step D4 is performed, or sub-step D5 is performed.
Substep D4: and taking the second neighbor cell as the access neighbor cell under the condition that the second neighbor cell is one neighbor cell.
Substep D5: and under the condition that the second adjacent cell is at least two adjacent cells, acquiring the second adjacent cell with the maximum throughput in the second adjacent cell, and taking the second adjacent cell with the maximum throughput as the access adjacent cell.
After the second neighboring cell is obtained, the number of the second neighboring cells may be determined, and in a case that the second neighboring cell is one neighboring cell, the second neighboring cell may be regarded as an access neighboring cell corresponding to the primary card.
When the second neighboring cell is at least two neighboring cells, the second neighboring cell with the largest throughput in the second neighboring cells may be obtained, and the second neighboring cell with the largest throughput is used as the access neighboring cell.
According to the embodiment of the application, under the condition that the main card is in the throughput sensitive scene information, the adjacent cell with the throughput higher than that of the target service cell can be obtained to serve as the access cell of the main card, the service processing efficiency can be improved, and if the smoothness of watching videos by a user is improved, the user experience is further improved.
