Description

A virtual SIM card switching method and device

technical field

The invention relates to the field of electronic technology, in particular to a virtual SIM card switching method and device.

Background technique

At present, most of the communication functions of mobile terminals need to rely on the physical SIM (Subscriber Identity Module) card. The SIM card is unique, that is, a SIM card corresponds to a communication number. Communication records are relied on for operations such as registration and encryption. With the development of social life and mobile communication services, people are no longer satisfied with only having a communication number (ie a SIM card) for communication. Usually, when the communication quality of the network of the operator to which a SIM card belongs is not good (such as weak signal strength), the user generally performs communication services by changing another SIM card belonging to a different operator. However, the ensuing problem is that current mobile terminals usually support physical SIM cards. When users encounter poor network communication quality of SIM cards, they need to manually replace SIM cards, even mobile phones that support virtual SIM cards. The terminal also requires the user to input a switching instruction before the mobile terminal can switch accordingly, which reduces the convenience of use and poor user experience.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flow diagram of a virtual SIM card switching method, the method flow can be implemented by a virtual SIM card switching device, the virtual SIM card switching device can be a user terminal or a software program running on a user terminal, the described The user terminal may include a mobile phone, a notebook computer, a tablet computer, a vehicle-mounted computer, a POS (Point Of Sales, point of sale) machine, and the like. As shown in the figure, the method at least includes:

Step S101 , detecting whether the communication service quality corresponding to the activated virtual SIM card meets the demand threshold of the currently used communication service.

Specifically, the activated virtual SIM card is a network-resident virtual SIM card or a virtual SIM card being used by a user. Communication service quality can be an index to measure the quality of the communication service currently used by the communication network, and can include multiple measurement parameters such as network signal strength, bit error rate, transmission speed or/and transmission delay. In different scenarios or different terminal devices, one of the measurement parameters can be used to characterize the communication service quality, and multiple or more can be used to calculate the normalized communication service quality, for example, only the network signal can be used The quality of the communication service can be represented by the strength of the intensity, and a normalized value can also be calculated through multiple measurement parameters such as the signal strength of the network, the bit error rate, the transmission speed or/and the transmission delay.

The communication service can be one or more of the communication forms that can be realized by the terminal using the virtual SIM card, such as making or answering calls, live video broadcasting, web browsing, and sending and receiving short messages. That is live video. The demand threshold of the communication service is the threshold value of the communication service quality required by the terminal to complete the corresponding communication task, that is, if the communication service quality corresponding to the virtual SIM card is lower than the communication service demand threshold , is unable to complete the current communication tasks well.

It should be noted that the communication service quality and the measurement standard of the communication service demand threshold are corresponding, that is to say, if the communication service quality is characterized by the parameter of signal strength, then the communication service demand threshold is also the predetermined A set signal strength value, if the quality of communication service is a normalized value expressed by multiple measurement parameters such as signal strength, bit error rate, transmission speed or/and transmission delay, then the demand threshold of communication services is also a predetermined value. A normalized representation value set by multiple measurement parameters such as signal strength, bit error rate, transmission speed or/and transmission delay.

In this embodiment, the terminal can obtain the communication service currently used by the user and the demand threshold corresponding to the communication service, and at the same time obtain the communication service quality corresponding to the virtual SIM card in the activated state, and then detect the service quality corresponding to the virtual SIM card in the activated state. Whether the communication service quality meets the demand threshold corresponding to the currently used communication service.

For example, the user is using the activated virtual SIM card in the terminal to make a call. Assume that the demand threshold of the call service is a signal strength of -80dBm, and the communication service quality corresponding to the activated virtual SIM card obtained by the terminal at this time is The signal strength of -50dBm, -50dBm is greater than -80dBm, indicating that the communication service quality corresponding to the activated virtual SIM card here can meet the demand threshold of the current communication service, which can enable the user to complete the call well.

For another example, the user is answering the phone with the activated virtual SIM card while browsing the web, assuming that the demand threshold for the call service is a normalized value of 0.2, and the demand threshold for web browsing is a normalized value of 0.6, and at this time the terminal The obtained communication service quality corresponding to the activated virtual SIM card is a normalized value of 0.5, then the communication service quality corresponding to the activated virtual SIM card here can meet the current call service, but cannot meet the current use The web browsing service, that is, the quality of communication service corresponding to the activated virtual SIM card does not meet the demand threshold of the currently used communication service.

Step S102, if the communication service quality corresponding to the activated virtual SIM card does not meet the requirement threshold of the currently used communication service, then detect the communication service quality corresponding to all downloaded virtual SIM cards.

Specifically, since the virtual SIM card is not a physical SIM card, as long as it is downloaded to the terminal, the terminal can obtain the registration information therein. The registration information includes the International Mobile Subscriber Identification Number (IMSI: International Mobile Subscriber Identification Number). According to IMSI, the mobile The communication network can uniquely identify the country to which the virtual SIM card belongs, the mobile communication network, and the mobile communication number bound to it, that is, the bound mobile user.

In this embodiment, the user may have multiple downloaded virtual SIM cards, that is, virtual SIM cards that have been authorized for use, which is equivalent to purchasing multiple physical SIM cards. Therefore, if it is detected in step S101 that the communication service quality corresponding to the activated virtual SIM card does not meet the demand threshold of the currently used communication service, then the terminal can provide communication services corresponding to other virtual SIM cards that have been downloaded in the terminal. Quality is tested.

During the specific detection process, according to the number of different SIM card chips existing in the terminal, the detection methods are also different. If there is only a single SIM card chip in the terminal, then the SIM card chip must be loaded with the currently active virtual SIM card, and in order to detect the communication service quality of other downloaded virtual SIM cards, the terminal needs to load it into the The SIM card chip can only be detected when it resides in the network for a short time. Therefore, it is necessary to log out the activated virtual SIM card first, and then load other downloaded virtual SIM cards in sequence for detection.

In this embodiment, the terminal may also have at least two SIM card chips, the first SIM card chip is used to load the activated virtual SIM card, and the other SIM card can be used to sequentially load other downloaded virtual SIM cards The quality of communication service is tested. In the specific detection process, the terminal can receive the signal of the nearby base station by staying on the network for a short time, so as to detect the signal strength. The terminal can also use the downloaded virtual SIM card to send a test message to the network server, and then determine the communication service quality according to the response of the network server, for example, determine the bit error rate, transmission speed or/and transmission time according to the message replied by the network server. Wait.

Step S103, if the communication service quality corresponding to at least one of the downloaded virtual SIM cards satisfies the demand threshold of the currently used communication service, then determine one of the virtual SIM cards in the at least one virtual SIM card card as the target virtual SIM card.

Specifically, through the communication service quality corresponding to all the downloaded virtual SIM cards detected in step S102, the terminal can obtain the virtual SIM card whose communication service quality can meet the demand threshold of the currently used communication service.

It should be noted that here, there may be one or more virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service. When the communication service quality corresponding to only one virtual SIM card in all downloaded virtual SIM cards meets the demand threshold of the currently used communication service, the terminal can directly determine that the virtual SIM card is the target virtual SIM card; when all the downloaded virtual SIM cards When there are multiple virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service in the virtual SIM card, the terminal can randomly select one of the virtual SIM cards as the target virtual SIM card, or according to certain preset rules, such as selecting The target virtual SIM card is determined by downloading the one with the earliest date, the highest usage rate, or the best communication service quality, etc.

Step S104, deregistering the activated virtual SIM card, and activating the target virtual SIM card to perform the communication service.

Specifically, after the terminal determines the target virtual SIM card whose communication service quality meets the demand threshold of the currently used communication service, it can cancel the activated virtual SIM card and activate the target virtual SIM card to perform the currently used communication service .

In this embodiment, there can be many situations for canceling the virtual SIM card in the activated state. It can be that the virtual SIM card in the activated state that was originally in use is erased in the SIM card chip, and loaded by the target virtual SIM card. In the SIM card chip, the target virtual SIM card is activated to use a new virtual SIM card as a user; in addition, canceling the activated virtual SIM card can also be to stop using the activated virtual SIM card in the currently used communication service card, the target virtual SIM card is activated to perform the currently used communication service, while other communication services can still be performed by the activated virtual SIM card.

It should be noted that, no matter which of the above situations, the deregistered virtual SIM card still exists in the storage space of the terminal together with other downloaded virtual SIM cards, and will not be deleted or invalidated. When the user switches the command or detects that the newly activated virtual SIM card cannot meet the demand threshold of the communication service, the canceled virtual SIM card can be reloaded into the SIM card chip for use.

For example, if there is only a single SIM card chip in the terminal, the terminal can erase the activated virtual SIM card in the SIM card chip and load the target virtual SIM card, so that the target virtual SIM card can be used as the virtual SIM card currently used by the user. Card, and then can perform the current communication service, such as re-dial, to achieve a better call experience.

For another example, if there are two SIM card chips in the terminal, and the currently used communication service is live video broadcasting, the terminal can stop the active virtual SIM card in the first SIM card chip from using the traffic service in the live video broadcasting, and Load the target virtual SIM card into the second SIM card chip, so that the traffic service in the target virtual SIM card can be used for live video broadcasting, but for other communication services, such as call services, the terminal can still use the activated first SIM card chip state of the virtual SIM card to perform.

In the embodiment of the present invention, when it is detected that the communication service quality corresponding to the virtual SIM card in the activated state does not meet the demand threshold of the currently used communication service, the communication service quality corresponding to all downloaded virtual SIM cards can be detected, and it can be based on the downloaded The quality of communication service of the virtual SIM card, intelligently select a target virtual SIM card whose communication service quality meets the demand threshold of the currently used communication service, and then cancel the activated virtual SIM card, and activate the target virtual SIM card to carry out communication services , so as to realize the intelligent switching of the virtual SIM card, thereby improving the convenience of use and improving the user experience.

Fig. 2 is a schematic flow chart of a virtual SIM card switching method in another embodiment of the present invention, the method comprising:

Step S201, detecting whether the communication service quality corresponding to the virtual SIM card in the activated state meets the demand threshold of the currently used communication service.

For a specific method, refer to step S101.

Step S202, if the communication service quality corresponding to the activated virtual SIM card does not meet the demand threshold of the currently used communication service, then detect the communication service quality corresponding to all downloaded virtual SIM cards.

For a specific method, refer to step 102.

Step S203, if the communication service quality corresponding to at least one of the downloaded virtual SIM cards meets the demand threshold of the currently used communication service, then determine that the communication service quality of the at least one virtual SIM card is the highest The optimal virtual SIM card is used as the target virtual SIM card.

Specifically, through the communication service quality corresponding to all the downloaded virtual SIM cards detected in step S202, the terminal can obtain the best communication service quality among the virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service. The virtual SIM card acts as the target virtual SIM card.

In an embodiment, there are multiple virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service, and among the virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service, the terminal The sorting may be performed according to the detection result in step S202, and the virtual SIM card with the best communication service quality may be selected as the target virtual SIM card.

For example, assuming that the demand threshold of the currently used communication service is 0.4, it is detected that among the downloaded virtual SIM cards, the communication service quality of three virtual SIM cards A, B, and C is greater than or equal to 0.4, and the communication service quality of A is respectively 0.5, B is 0.7, and C is 0.4. The terminal can determine that B is the virtual SIM card with the best communication service quality, and then it can determine that B is the target virtual SIM card.

Optionally, this step may also be: determining a virtual SIM card with the highest priority among the at least one virtual SIM card as the target virtual SIM card.

Specifically, the user can preset the priority of the virtual SIM card that he has downloaded. For example, the priority of the card 1 with a large recharge amount can be preset as 1, and the priority of the card 2 that is not commonly used is 2. Then the terminal After acquiring the priorities of the virtual SIM cards, it may be determined which virtual SIM card to acquire as the target virtual SIM card according to the order of the priorities. In the above example, the terminal may select card 1 with priority 1 as the target virtual SIM card.

Step S204, deregistering the activated virtual SIM card, and activating the target virtual SIM card to perform the communication service.

For a specific method, refer to step S104.

Optionally, the method may also include:

Determine the communication service quality of the virtual SIM card in the activated state according to the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the virtual SIM card in the activated state belongs;

or/and,

Determine the communication service quality of the downloaded virtual SIM card according to the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the downloaded virtual SIM card belongs.

Specifically, a preset weight coefficient may be obtained, and the signal strength, bit error rate, transmission speed, and transmission delay are weighted according to the weight coefficient to generate the communication service quality of the virtual SIM.

For example, according to the formula

result=A×a+B×b+C×c+D×d,

a+b+c+d=1

Calculate the communication service quality of virtual SIM, wherein, preferably, A is the normalized value of signal strength, B is the normalized value of bit error rate, C is the normalized value of transmission speed, D is the normalized value of transmission time delay normalized value. a, b, c, d are the corresponding weighting coefficients respectively. It can be assumed that a=0.4, b=0.2, c=0.1, d=0.3, so as to calculate the normalized value of the communication service quality.

Furthermore, in an optional embodiment, the communication service quality may be determined according to a unified normalized value of the communication service quality.

It should be noted that this method can be used to calculate the communication service quality of the activated virtual SIM card, and can also be used to calculate the communication service quality of the downloaded virtual SIM card. When the terminal calculates the communication service quality of the virtual SIM card in the activated state, it can obtain the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the virtual SIM card in the activated state belongs to calculate; When calculating the communication service quality of the downloaded virtual SIM card, the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the downloaded virtual SIM card belongs can be obtained for calculation.

Optionally, the method may also include:

Send a virtual SIM card download request to the cloud server.

Specifically, when there is no virtual SIM card other than the activated virtual SIM card in the terminal, or when the user has other virtual SIM cards that have not been downloaded but purchased, the terminal can send the virtual SIM card to the cloud server. A card download request to request the cloud server to send a virtual SIM card corresponding to the virtual SIM card download request.

receiving the virtual SIM card sent by the cloud server according to the virtual SIM card download request.

Specifically, the cloud server stores a large number of virtual SIM cards, and the user of the terminal can pass the verification of the cloud server according to the verification method obtained at the time of purchase, and then the cloud server can obtain the corresponding virtual SIM cards and send them to the terminal. After the terminal receives the virtual SIM card, it can further execute the methods in the foregoing embodiments.

In the embodiment of the present invention, when it is detected that the communication service quality corresponding to the virtual SIM card in the activated state does not meet the demand threshold of the currently used communication service, the communication service quality corresponding to all downloaded virtual SIM cards can be detected, and it can be based on the downloaded The quality of communication service of the virtual SIM card, intelligently select a target virtual SIM card whose communication service quality meets the demand threshold of the currently used communication service, and then cancel the activated virtual SIM card, and activate the target virtual SIM card to carry out communication services , so as to realize the intelligent switching of the virtual SIM card, thereby improving the convenience of use and improving the user experience.

Fig. 3 is the composition structural diagram of a kind of virtual SIM card switching device in the embodiment of the present invention, and this device comprises:

The demand detection module 310 is configured to detect whether the communication service quality corresponding to the activated virtual SIM card meets the demand threshold of the currently used communication service.

Specifically, the activated virtual SIM card is a network-resident virtual SIM card or a virtual SIM card being used by a user. Communication service quality can be an index to measure the quality of the communication service currently used by the communication network, and can include multiple measurement parameters such as network signal strength, bit error rate, transmission speed or/and transmission delay. In different scenarios or different terminal devices, one of the measurement parameters can be used to characterize the communication service quality, and multiple or more can be used to calculate the normalized communication service quality, for example, only the network signal can be used The quality of the communication service can be represented by the strength of the intensity, and a normalized value can also be calculated through multiple measurement parameters such as the signal strength of the network, the bit error rate, the transmission speed or/and the transmission delay.

The communication service can be one or more of the communication forms that can be realized by the terminal using the virtual SIM card, such as making or answering calls, live video broadcasting, web browsing, and sending and receiving short messages. That is live video. The demand threshold of the communication service is the threshold value of the communication service quality required by the terminal to complete the corresponding communication task, that is, if the communication service quality corresponding to the virtual SIM card is lower than the communication service demand threshold , is unable to complete the current communication tasks well.

It should be noted that the communication service quality and the measurement standard of the communication service demand threshold are corresponding, that is to say, if the communication service quality is characterized by the parameter of signal strength, then the communication service demand threshold is also the predetermined A set signal strength value, if the quality of communication service is a normalized value expressed by multiple measurement parameters such as signal strength, bit error rate, transmission speed or/and transmission delay, then the demand threshold of communication services is also a predetermined value. A normalized representation value set by multiple measurement parameters such as signal strength, bit error rate, transmission speed or/and transmission delay.

In this embodiment, the demand detection module 310 can obtain the communication service currently used by the user and the demand threshold corresponding to the communication service, and at the same time obtain the communication service quality corresponding to the virtual SIM card in the activated state, and then detect the virtual SIM card in the activated state. Whether the communication service quality corresponding to the card meets the demand threshold corresponding to the currently used communication service.

For example, the user is using the activated virtual SIM card in the terminal to make a call. Assume that the demand threshold of the call service is a signal strength of -80dBm. At this time, the communication corresponding to the activated virtual SIM card obtained by the demand detection module 310 The quality of service is a signal strength of -50dBm, and -50dBm is greater than -80dBm, indicating that the communication service quality corresponding to the activated virtual SIM card here can meet the demand threshold of the current communication service, which can enable the user to complete the call well.

For another example, the user is answering the phone with the activated virtual SIM card and browsing the web at the same time. Assume that the demand threshold for the call service is a normalized value of 0.2, and the demand threshold for web browsing is a normalized value of 0.6. At this time, the demand The communication service quality corresponding to the activated virtual SIM card acquired by the detection module 310 is a normalized value of 0.5, then the communication service quality corresponding to the activated virtual SIM card here can meet the current call service, but cannot meet The currently used web browsing service, that is, the quality of communication service corresponding to the activated virtual SIM card does not meet the demand threshold of the currently used communication service.

The quality detection module 320 is configured to detect the communication service quality corresponding to all downloaded virtual SIM cards if the communication service quality corresponding to the activated virtual SIM card does not meet the demand threshold of the currently used communication service.

Specifically, since the virtual SIM card is not a physical SIM card, as long as it is downloaded to the terminal, the terminal can obtain the registration information therein. The registration information includes the International Mobile Subscriber Identification Number (IMSI: International Mobile Subscriber Identification Number). According to IMSI, the mobile The communication network can uniquely identify the country to which the virtual SIM card belongs, the mobile communication network, and the mobile communication number bound to it, that is, the bound mobile user.

In this embodiment, the user may have multiple downloaded virtual SIM cards, that is, virtual SIM cards that have been authorized for use, which is equivalent to purchasing multiple physical SIM cards. Therefore, if it is detected in the demand detection module 310 that the communication service quality corresponding to the virtual SIM card in the activated state does not meet the demand threshold of the currently used communication service, the quality detection module 320 can check the quality of other virtual SIM cards that have been downloaded in the terminal. The communication service quality corresponding to the card is detected.

During the specific detection process, according to the number of different SIM card chips existing in the terminal, the detection methods are also different. If there is only a single SIM card chip in the terminal, then the SIM card chip must be loaded with the currently active virtual SIM card, and in order to detect the communication service quality of other downloaded virtual SIM cards, the terminal needs to load it into the The SIM card chip can be detected only when it resides in the network for a short period of time. Therefore, the quality detection module 320 needs to deregister the activated virtual SIM card first, and then load other downloaded virtual SIM cards in sequence for detection.

The quality detection module 320 can also use the downloaded virtual SIM card to send a test message to the network server, and then determine the communication service quality according to the response of the network server, for example, determine the bit error rate, transmission speed or/or and transmission delay, etc.

The target determination module 330 is configured to determine that the communication service quality corresponding to at least one virtual SIM card in the downloaded virtual SIM card meets the demand threshold of the currently used communication service, then determine the One of the virtual SIM cards in the target virtual SIM card.

Specifically, through the communication service quality corresponding to all downloaded virtual SIM cards detected in the quality detection module 320, the target determination module 330 can obtain the virtual SIM card whose communication service quality can meet the demand threshold of the currently used communication service.

It should be noted that here, there may be one or more virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service. When all the virtual SIM cards that have been downloaded only have the corresponding communication service quality of a virtual SIM card to meet the demand threshold of the communication service currently used, then the target determination module 330 can directly determine that the virtual SIM card is the target virtual SIM card; when all When there are multiple virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service in the downloaded virtual SIM cards, the target determination module 330 can randomly select one of the virtual SIM cards as the target virtual SIM card, or according to a certain Preset rules, such as selecting the one with the earliest download date, the highest usage rate, or the best communication service quality, etc., to determine the target virtual SIM card.

The target determination module 330 is used for:

Determining a virtual SIM card with the best communication service quality among the at least one virtual SIM card as the target virtual SIM card.

Specifically, through the communication service quality corresponding to all downloaded virtual SIM cards detected in the quality detection module 320, the target determination module 330 can obtain the communication service quality in the virtual SIM card whose communication service quality can meet the demand threshold of the currently used communication service. The virtual SIM card with the best service quality is used as the target virtual SIM card.

In an embodiment, there are multiple virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service, and among the virtual SIM cards whose communication service quality can meet the demand threshold of the currently used communication service, the terminal The sorting can be performed according to the detection results of the quality detection module 320, and the virtual SIM card with the best communication service quality can be selected as the target virtual SIM card.

For example, assuming that the demand threshold of the currently used communication service is 0.4, it is detected that among the downloaded virtual SIM cards, the communication service quality of three virtual SIM cards A, B, and C is greater than or equal to 0.4, and the communication service quality of A is respectively 0.5, B is 0.7, and C is 0.4. The target determination module 330 may determine that B is the virtual SIM card with the best communication service quality, and then determine B as the target virtual SIM card.

The target determination module 330 is used for:

Determining a virtual SIM card with the highest priority among the at least one virtual SIM card as the target virtual SIM card.

Specifically, the user can preset the priority of the virtual SIM card that he has downloaded. For example, the priority of card 1 with a large recharge amount can be preset as 1, and the priority of card 2 that is not commonly used is 2. Then the target After acquiring the priorities of the virtual SIM cards, the determining module 330 may determine which virtual SIM card to acquire as the target virtual SIM card according to the sequence of priorities. In the above example, the target determining module 330 may select card 1 with priority 1 as the target virtual SIM card.

The deactivation activation module 340 is configured to deregister the activated virtual SIM card, and activate the target virtual SIM card to perform the communication service.

Specifically, after the target determination module 330 determines that the communication service quality meets the target virtual SIM card whose communication service quality meets the demand threshold of the currently used communication service, the cancellation activation module 340 can cancel the virtual SIM card in the activated state, and activate the target virtual SIM card To carry out the current communication service.

In this embodiment, there can be many situations for canceling the virtual SIM card in the activated state. It can be that the virtual SIM card in the activated state that was originally in use is erased in the SIM card chip, and loaded by the target virtual SIM card. In the SIM card chip, the target virtual SIM card is activated to use a new virtual SIM card as a user; in addition, canceling the activated virtual SIM card can also be to stop using the activated virtual SIM card in the currently used communication service card, the target virtual SIM card is activated to perform the currently used communication service, while other communication services can still be performed by the activated virtual SIM card.

It should be noted that, no matter which of the above situations, the deregistered virtual SIM card still exists in the storage space of the terminal together with other downloaded virtual SIM cards, and will not be deleted or invalidated. When the user switches the command or detects that the newly activated virtual SIM card cannot meet the demand threshold of the communication service, the canceled virtual SIM card can be reloaded into the SIM card chip for use.

For example, if there is only a single SIM card chip in the terminal, the deactivation activation module 340 can erase the activated virtual SIM card in the SIM card chip and load the target virtual SIM card, so that the target virtual SIM card can be used as the user The virtual SIM card, and then can perform the current communication service, such as redialing, to achieve a better call experience.

For another example, if there are two SIM card chips in the terminal, and the currently used communication service is live video broadcasting, the deactivation activation module 340 can stop the virtual SIM card in the activated state in the first SIM card chip from using the traffic service in the live video broadcasting status, and load the target virtual SIM card into the second SIM card chip, so as to use the traffic service in the target virtual SIM card for live video broadcasting, but for other communication services, such as call services, the first SIM card chip can still be used Activated virtual SIM card to execute.

Optionally, the device further includes: a quality determination module 350, configured to determine the The communication service quality of the virtual SIM card in the activated state;

or/and,

It is used for determining the communication service quality of the downloaded virtual SIM card according to the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the downloaded virtual SIM card belongs.

Specifically, the quality determination module 350 can obtain a preset weight coefficient, and weight the signal strength, bit error rate, transmission speed, and transmission delay according to the weight coefficient to generate the communication service quality of the virtual SIM.

For example, according to the formula

result=A×a+B×b+C×c+D×d,

a+b+c+d=1

Calculate the communication service quality of virtual SIM, wherein, preferably, A is the normalized value of signal strength, B is the normalized value of bit error rate, C is the normalized value of transmission speed, D is the normalized value of transmission time delay normalized value. a, b, c, d are the corresponding weighting coefficients respectively. It can be assumed that a=0.4, b=0.2, c=0.1, d=0.3, so as to calculate the normalized value of the communication service quality.

Furthermore, in an optional embodiment, the quality determining module 350 may determine the communication service quality according to a unified normalized value of the communication service quality.

It should be noted that this method can be used to calculate the communication service quality of the activated virtual SIM card, and can also be used to calculate the communication service quality of the downloaded virtual SIM card. When the terminal calculates the communication service quality of the virtual SIM card in the activated state, it can obtain the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the virtual SIM card in the activated state belongs to calculate; When calculating the communication service quality of the downloaded virtual SIM card, the signal strength, bit error rate, transmission speed or/and transmission delay of the communication network to which the downloaded virtual SIM card belongs can be obtained for calculation.

Optionally, the device further includes: a request module 360, configured to send a virtual SIM card download request to the cloud server.

Specifically, when there is no virtual SIM card other than the activated virtual SIM card in the terminal, or when the user has other virtual SIM cards that have not been downloaded but have been purchased, the request module 360 can send a message to the cloud server. The virtual SIM card download request is to request the cloud server to send the virtual SIM card corresponding to the virtual SIM card download request.

Optionally, the device further includes: a receiving module 370, configured to receive the virtual SIM card sent by the cloud server according to the virtual SIM card download request.

Specifically, the cloud server stores a large number of virtual SIM cards, and the user of the terminal can pass the verification of the cloud server according to the verification method obtained at the time of purchase, and then the cloud server can obtain the corresponding virtual SIM cards and send them to the terminal. After the receiving module 370 receives the virtual SIM card, it can further execute the methods in the above-mentioned embodiments.

In the embodiment of the present invention, when it is detected that the communication service quality corresponding to the virtual SIM card in the activated state does not meet the demand threshold of the currently used communication service, the communication service quality corresponding to all downloaded virtual SIM cards can be detected, and it can be based on the downloaded The quality of communication service of the virtual SIM card, intelligently select a target virtual SIM card whose communication service quality meets the demand threshold of the currently used communication service, and then cancel the activated virtual SIM card, and activate the target virtual SIM card to carry out communication services , so as to realize the intelligent switching of the virtual SIM card, thereby improving the convenience of use and improving the user experience.
