S304: and executing data service switching processing according to the detection results of the first data link quality and the second data link quality.

In this embodiment of the present application, the performing data service switching processing according to the detection result of the first data link quality and the second data link quality includes two cases:

in the first case: and when the first data link quality and the second data link quality are determined to be successfully detected, if the first data link quality and the second data link quality meet a second switching condition, switching to a state of executing data service through the second subscriber identity module card.

In this embodiment of the present application, the first data link quality and the second data link quality satisfy a second handover condition, including:

the first RTT (Round-Trip Time ) is greater than or equal to the second Round-Trip Time RTT;

the first RTT is used to indicate the quality of the first data link, and the first RTT is generated according to first test information and first feedback information, that is, the first RTT is a time interval length between a time when the terminal sends the first test information and a time when the terminal receives the first feedback information; the second RTT is used to indicate the quality of the second data link, and the second RTT is generated according to second test information and second feedback information, that is, the second RTT is a time interval length between a time when the terminal sends the first test information and a time when the terminal receives the second feedback information.

In the first case, before performing the switching to the state of performing the data service by the second subscriber identity card, the designation information may be introduced, and in combination with the designation information and the second preset condition, it may be determined whether to perform the switching to the state of performing the data service by the second subscriber identity card.

Wherein, the said appointed information is used for appointing to carry out the data service through the said first subscriber identity identification card. The designation information may be sent by the user to the terminal, such as: the user manually inputs the designated information on the terminal screen, such as: the user operation terminal is used for appointing a key for executing the data service through the first user identification card so as to send appointed information to the terminal; the designation information may also be sent to the terminal by the first data network or the second data network.

In a first case, when it is determined that the first data link quality and the second data link quality are successfully detected and the first data link quality and the second data link quality satisfy the second handover condition, if the specific information is not received, the terminal switches to a state where the data service is performed through the second subscriber identity card.

In a first case, that is, when it is determined that the first data link quality and the second data link quality are successfully detected and the first data link quality and the second data link quality satisfy the second handover condition, if the specific information is received, the state of performing the data service by the second subscriber identity card is switched according to the data link quality threshold.

In this embodiment of the present application, the switching to the state of executing the data service by using the second subscriber identity module card according to the data link quality threshold includes:

and if the second RTT is less than the data link quality threshold and the first RTT is greater than or equal to the data link quality threshold, switching to a state of executing data service through the second subscriber identity module card.

Wherein the data link quality threshold may be an RTT threshold. The RTT threshold may be set by a user on the terminal, or set when the terminal leaves a factory or the system is initialized, or may be set in other manners, which is not described herein.

In the embodiment of the present application, when it is determined that the first data link quality and the second data link quality are successfully detected, and the first data link quality and the second data link quality satisfy the second handover condition, and when the specific information is received, if the second RTT is less than or equal to the first RTT and less than the RTT threshold, or if the RTT threshold is less than or equal to the second RTT and less than the first RTT, the terminal does not perform handover to a state where the data service is executed by the second subscriber identity card, and is still in a state where the data service is executed by the first subscriber identity card.

In the second case: and if the second data link quality is successfully detected and the first data link quality is not detected, switching to a state of executing the data service through the second subscriber identity module card.

In this embodiment of the present application, if it is determined that the second data link quality is successfully detected and the first data link quality is not detected, the first signal quality threshold is updated, so that the updated first signal quality threshold is greater than the first signal quality threshold before updating.

If the first data link quality is not detected, it is known that the first data link quality has become poor, the first signal quality threshold is increased, and the data service switching process can be performed in a subsequent earlier trigger.

Specifically, first candidate quality thresholds of different grades may be preset, and the higher the grade is, the larger the first candidate quality threshold is, for example: setting first alternative quality thresholds of six levels of-85 dBm, -83dBm, -81dBm, -79dBm, -77dBm and-75 dBm, and the levels are sequentially increased; determining one of the first candidate quality thresholds as an initial first signal quality threshold, such as: determining-85 dBm as an initial first signal quality threshold; if it is determined that the second data link quality is successfully detected and the first data link quality is not detected, the first signal quality threshold may be updated to a higher level first alternative quality threshold, such as: updating the first signal quality threshold to-81 dBm with two levels higher; the number of levels for updating the up-regulation first signal quality threshold each time may be set in advance by the user equipment, or automatically by the terminal system according to the first data network, which is not described herein.

In this embodiment of the present application, when it is determined that the first data link quality and the second data link quality are successfully detected, if the first RTT is less than a data link quality threshold, the first signal quality threshold is updated, so that the updated first signal quality threshold is less than a first signal quality threshold before updating.

Such as: determining-81 dBm as an initial first signal quality threshold, and updating the first signal quality threshold to-85 dBm of two lower levels if the first RTT is less than the initial data link quality threshold when the first data link quality and the second data link quality are successfully detected; the level of the first signal quality threshold adjusted downward in each update may be set in advance by the user equipment, or automatically by the terminal system according to the first data network, which is not described herein again.

When it is determined that the first data link quality and the second data link quality are successfully detected, if the first RTT is less than a data link quality threshold, updating the first signal quality threshold, where the three cases include:

the first condition is as follows: and when the first data link quality and the second data link quality are determined to be successfully detected, if the first RTT is less than the second RTT and the first RTT is less than the RTT threshold, updating the first signal quality threshold so that the updated first signal quality threshold is less than the first signal quality threshold before updating, and not executing data service switching processing.

The first RTT is less than the second RTT, and the first RTT is less than the RTT threshold, so that the quality of the first data link is relatively good, the quality of the first data link and the quality of the second data link can be prevented from being triggered and detected frequently according to the first signal quality subsequently by reducing the first signal quality threshold, and the time delay for increasing the unnecessary detection data link quality and the consumption of wireless resources are avoided.

Case two: when the first data link quality and the second data link quality are determined to be successfully detected, if the first RTT is greater than or equal to the second RTT, no specified information is received, and the first RTT is smaller than the RTT threshold, updating the first signal quality threshold to enable the updated first signal quality threshold to be smaller than the first signal quality threshold before updating, and executing switching to a state of executing data service through the second subscriber identity module card.

From the first RTT < the RTT threshold, it can be known that the first data link quality is relatively good, and the first signal quality threshold can be reduced, so that the first data link quality and the second data link quality are prevented from being frequently triggered and detected according to the first signal quality, and time delay and radio resource consumption which increase unnecessary data link quality are avoided.

Case three: and when the first data link quality and the second data link quality are determined to be successfully detected, if the first RTT is greater than or equal to the second RTT, the specified information is received, and the first RTT is less than the RTT threshold, updating the first signal quality threshold, so that the updated first signal quality threshold is less than the first signal quality threshold before updating, and the data service switching processing is not executed.

From the first RTT ≧ the second RTT, and the first RTT < the RTT threshold, it can be known that although the quality of the second data link is better than the quality of the first data link, the first data link can still better carry data traffic, and in the case of receiving the specific information, that is, in the case where the user wishes to remain in the state of executing data traffic through the first user id card for a long time, the data traffic switching may not be executed, and in order to avoid frequent subsequent detection of the quality of the data link, the first signal quality threshold may be lowered.

In this embodiment of the present application, if it is determined that the second data link quality is not detected, the second signal quality threshold is updated, so that the updated second signal quality threshold is greater than the second signal quality threshold before updating, and the data service switching process is not performed.

If the quality of the second data link is not detected, the quality of the second data link is considered to be poor, and the second signal quality threshold is improved, namely, the standard for triggering and detecting the quality of the data link according to the second signal quality is improved, so that the condition that the quality of the first data link and the quality of the second data link are triggered and detected frequently in the follow-up process is avoided, and the time delay and the consumption of wireless resources for unnecessarily detecting the quality of the data link are avoided.

Specifically, second candidate quality thresholds of different levels may be preset, and the higher the level is, the larger the second candidate quality threshold is, for example: setting second alternative quality thresholds of six levels of-85 dBm, -83dBm, -81dBm, -79dBm, -77dBm and-75 dBm, and the levels are sequentially increased; determining one of the second candidate quality thresholds as an initial second signal quality threshold, such as: determining-85 dBm as an initial second signal quality threshold; if the second data link quality is not detected, the second signal quality threshold may be updated to a second alternative quality threshold of higher level, such as: updating the initial second signal quality threshold to-81 dBm with two levels higher; the number of levels for updating and up-regulating the second signal quality threshold each time may be set in advance by the user equipment, or automatically by the terminal system according to the second data network, which is not described herein.

In this embodiment of the application, if the specific information is received, after the state of performing the data service by using the second subscriber identity module card is switched, step S305 is executed.

Specifically, if the specified information is received, after the state of performing the data service by using the second subscriber identity module card is switched, it is determined whether the second subscriber identity module card resides in a second data network; if the second subscriber identity module card resides in the second data network, step S305 is executed.

Wherein, the said appointed information is used for appointing to carry out the data service through the said first subscriber identity identification card. The designation information may be received before or after the terminal switches to a state in which the data service is performed through the second subscriber identity card.
