Description

SIM card switching method and device

Technical Field

The present disclosure relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for switching an SIM card.

Background

A multi-card smart terminal (e.g., a dual-card mobile phone) supports multiple SIM (Subscriber Identity Module) cards inserted into the smart terminal to run on a cellular network at the same time, but a data traffic channel can only be established on one of the SIM cards, i.e., a user of the dual-card mobile phone cannot realize that 2 SIMs keep on-line at the same time.

The SIM card with data traffic is often referred to as the primary card and the SIM card without data traffic is the secondary card. In the related art, due to the limitation of hardware and protocol stack of the smart terminal, when the main card runs a high-speed network (e.g., 4G network), the secondary card can only be attached to a low-speed network (e.g., 2G, 3G network). With the change of network environment, the mobile network where the main card and the auxiliary card are located may be switched between a high-speed network and a low-speed network, and if the mobile network where the main card is located is reduced from the high-speed network to the low-speed network, the mobile internet access speed of the user will be greatly reduced. For example, a dual-card mobile phone includes a card a and a card B, where the network of the card a belongs to an operator a, and the network of the card B belongs to an operator B, where the card a is a primary card, the card B is a secondary card, and the card B is attached to a low-speed network. The user accesses the internet through the mobile network of the card a, if the card a operates on a high-speed network (e.g., a 4G network), the user can enjoy a faster mobile internet access speed, and if the card a is reduced from the high-speed network to a low-speed network, the mobile internet access speed of the user is greatly reduced.

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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a SIM card switching method according to an exemplary embodiment, where the method is used in a smart terminal supporting multiple SIM cards, where the smart terminal includes at least a first SIM card and a second SIM card, and the method may include the following steps.

In step S110, network information of a mobile network where the first SIM card is located is obtained, where a data traffic channel is established on the first SIM card.

In this embodiment, the data traffic channel is established based on the first SIM card, that is, the first SIM card is a master card.

In an exemplary embodiment of the present disclosure, the MODEM communication module in the smart terminal may acquire network information of a mobile network in which the first SIM card operates, and the MODEM communication module is responsible for mobile network protocol exchange and a specific data communication process, so that the MODEM communication module can acquire all network information of the mobile network in which the SIM card operates. The network information to which the present disclosure relates may include at least one of a network type of the mobile network, a transmission speed.

In step S120, determining whether the first SIM card is switched from a first network to a second network according to the network information, wherein a network speed of the second network is lower than a network speed of the first network; if yes, go to step S130; otherwise, the current flow is ended.

The first network, the second network and the third network do not refer to a certain network, but refer to a certain type of mobile network respectively. The Mobile network in the present disclosure does not refer to a network operated by a certain operator, but refers to a cellular network, such as TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), CDMA (Code Division Multiple Access), GSM (Global System for Mobile Communication), etc.

For example, if the first SIM card originally operates in a 4G mobile network and is later switched to a 3G mobile network, the first network is the 4G network and the second network is the 3G network.

In an exemplary embodiment of the present disclosure, the network information includes a network type, and then a current network type corresponding to the first SIM card is compared with a network type at a previous time, and if the current network type is lower than the network type at the previous time, it is determined that the first SIM card is switched from the first network to the second network. For example, if the network type of the mobile network currently operated by the first SIM card is 4G, and the network type of the mobile network operated at the last time is 3G, the first SIM card is considered to be switched from the first network to the second network.

In another exemplary embodiment of the present disclosure, the network information includes a transmission speed, a current transmission speed corresponding to the first SIM card is compared with a transmission speed at a previous time, and if the current transmission speed is lower than the transmission speed at the previous time and a difference between the current transmission speed and the transmission speed reaches a preset strength difference, it is determined that the first SIM card is switched from the first network to the second network. For example, if the current transmission speed of the first SIM card is in the range of the 3G network, and the transmission speed at the last time is in the range of the 4G network, the first SIM card is considered to be switched from the first network to the second network.

In step S130, determining whether a third network exists in the neighboring cell of the second SIM card, where a network speed of the third network is higher than a network speed of the second network; if yes, go to step S140; otherwise, the current flow is ended.

Network information of all neighbor cells of a mobile network where the secondary card is located is obtained, whether a third network with network speed meeting requirements exists in the neighbor cells is judged according to the network information, and the network speed of the third network is higher than that of the second network.

The operators of the mobile networks in which the second SIM card and the first SIM card are located should not be the same. If the operators of the mobile networks of the first SIM card and the second SIM card are the same, and the SIM card switching logic is not started.

In an exemplary embodiment of the disclosure, the MODEM communication module may be configured to acquire the network types of the second network and the neighbor cells of the second SIM card, and determine whether a third network with a network type higher than that of the second network exists in the neighbor cells of the second SIM card. For example, the neighbor cells of the second SIM card include a network with a network type of 4G, and the second network is a 3G network, and at this time, it is determined that a third network with a network speed meeting the requirement exists in the neighbor cells of the second SIM card.

In another exemplary embodiment of the present disclosure, the MODEM communication module may be configured to directly obtain the transmission speeds of the second network and the neighbor cells of the second SIM card, and then determine whether a third network with a transmission speed higher than that of the second network exists in the neighbor cells of the second SIM card. And when a network with the transmission speed higher than that of the second network exists in the neighbor cell of the second SIM card, the third network with the network speed meeting the requirement exists in the neighbor cell of the second SIM card.

In step S140, the second SIM card is switched to the third network, a data traffic channel established by the mobile network based on the second SIM card is enabled, and the data traffic channel established based on the first SIM card is closed.

And setting the second SIM card as a main card, starting a data flow channel established by the mobile network based on the second SIM card, and setting the second SIM card to preferentially use the network with higher transmission speed, namely the third network. Meanwhile, the first SIM card is defaulted as an auxiliary card, a data flow channel established based on the first SIM card is closed, and the first SIM card is attached to the low-speed network.

For example, the first SIM card is dropped from a 4G mobile network to a 3G mobile network, and a 4G mobile network exists in a neighboring cell of the second SIM card, at this time, the second SIM card is set as a primary card, and at the same time, the first SIM card is defaulted as a secondary card. And using a data traffic channel established by the mobile network based on the second SIM card, and configuring the first SIM card as a limited-use high-speed network. And meanwhile, closing a data traffic channel established by the mobile network based on the first SIM card.

The SIM card switching method provided in this embodiment obtains network information of a mobile network in which a first SIM card is located, where the first SIM card is a main card. When determining whether the first SIM card is switched from a first network with high transmission speed to a second network with low transmission speed according to the network information of the first SIM card, judging whether a third network with the transmission speed higher than that of the second network exists in a neighbor cell of the second SIM card (namely a secondary card); if a third network exists in the neighbor cell of the second SIM card, the second SIM card is switched to the third network of the neighbor cell, and a data flow channel of the second SIM card is started, and meanwhile, the data flow channel of the first SIM card is closed, so that the data flow can be switched among different networks with higher transmission speed, and a user can operate in a high-speed network environment as much as possible, and the mobile network speed of the user is improved.

Fig. 2 is a flowchart illustrating another SIM card switching method according to an exemplary embodiment, where the method is applied to a smart terminal, where the smart terminal includes at least a first SIM card and a second SIM card, and as shown in fig. 2, the method may further include step S210 based on fig. 1.

In step S120, determining whether the first SIM card is switched from a first network to a second network according to the network information, wherein a network speed of the second network is lower than a network speed of the first network; if yes, go to step S210; otherwise, the current flow is ended.

In step S210, counting an operation duration for switching the first SIM card to the second network, and determining whether the operation duration is not less than a first preset time threshold; if yes, step S130 is executed, otherwise, the current flow is ended.

And starting the timer after judging that the first SIM card is switched to the second network with lower transmission speed, and stopping the timer when detecting that the first SIM card is switched to the third network with higher transmission speed. If the timer reaches the first preset time threshold before receiving the stop timing signal, the SIM card switching logic is started, i.e. step S130 is executed.

The first preset time threshold may be set according to actual conditions, for example, 40 s. If the first preset time threshold is too long, the SIM card can not be switched timely, and the mobile internet speed of the user is influenced; if the first preset time threshold is too short, frequent switching of the SIM card may be caused, and resources of the intelligent terminal are occupied.

According to the SIM card switching method provided by the embodiment, when the first SIM card is switched to the second network with lower transmission speed and reaches the first preset time threshold, the SIM card switching logic is executed, so that the phenomena that the mobile network where the first SIM card is located is unstable and the SIM cards are frequently switched are avoided, the mobile internet speed of a user is relatively stable, the user can be enabled to seamlessly switch among different high-speed networks, and the overall mobile internet speed of the user is improved.

Fig. 3 is a flowchart illustrating a method of step S130 according to an exemplary embodiment, and step S130 in fig. 1 or fig. 2 may include the following steps:

in step S131, network information of a neighboring cell of the second SIM card is obtained according to a preset period, so as to obtain a cell list.

The MODEM communication module may acquire network information of a neighbor cell of a mobile network in which the second SIM card is located. The MODEM communication module may periodically acquire network information of neighbor cells of the second SIM card, and obtain a cell list including the network information of each neighbor cell. The network information may include a network type and a transmission speed.

The preset period can be set according to actual needs, for example, 5 min.

In step S132, the cell list is scanned, it is determined whether a mobile network with a network speed higher than that of the second network exists in the neighboring cells of the second SIM card, and when a mobile network with a network speed higher than that of the second network exists in the cell list, it is determined that the third network exists in the neighboring cells of the second SIM card.

And scanning a network information cell list of a neighbor cell containing a second SIM card, judging whether a mobile network with the network speed higher than that of the second network exists in the cell list, and if so, determining that the second SIM card meets the switching condition.

Network type determination may be utilized, for example, the network speed of a 4G mobile network is higher than that of a 3G, 2G mobile network; the network speed of the 3G mobile network is higher than that of the 2G mobile network. When a new generation mobile network is introduced in the future, the network speed of the new generation mobile network is higher than that of the 2G, 3G and 4G mobile networks.

The determination may also be directly made according to the obtained transmission speed of the mobile network, please refer to the related description above, which is not described herein again.
