The single-card multimode module comprises a SIM card holder 110, a first network component 120 and a second network component 130, wherein the SIM card holder 110 is used for inserting a SIM card; the first network component 120 is connected to the SIM card holder 110, and is configured to determine, in an awake mode, whether the SIM card is a narrowband internet of things card: if the SIM card is a narrowband internet of things card, the first network component 120 registers a narrowband internet of things network, and if the SIM card is not a narrowband internet of things card, the first network component 120 enters a sleep mode; the second network component 130 is connected to the first network component 120, and is configured to enter a working mode and transmit the working mode to the SIM card holder 110 when the first network component 120 enters a sleep mode, and determine whether the type of the SIM card is a preset type, if so, the second network component 130 registers a network corresponding to the preset type, and if not, the second network component 130 exits the working mode. The second network component 130 is transmitted to the SIM card holder 110 through the first network component 120, and performs single-card multimode switching when the first network component 120 enters the sleep mode, so that switching between multiple network modes can be accurately and efficiently implemented, and user experience is improved.
The embodiment of the application also provides a single-card multimode switching method which is applied to the single-card multimode module, as shown in fig. 3, and comprises the following steps:
step 302, controlling a first network component, and judging whether the SIM card inserted in the SIM card seat is a narrow-band Internet of things card or not in an awake mode; if the SIM card is a narrowband Internet of things card, the first network component registers a narrowband Internet of things network; if the SIM card is not a narrowband Internet of things card, the first network component enters a sleep mode;
after the first network component is electrified, the power-on can be performed by pressing a power-on button. After the power-on, the first network component enters an awakening mode, in the awakening mode, the first network component inquires whether the public network supports the NB network or not and judges whether the SIM card is a narrow-band Internet of things card, if the SIM card is the NB card, the first network component normally performs network injection operation, and the second network component is in a power-off state. If the SIM card used is a non-NB card, the first network component enters a sleep mode.
Step 304, when the first network component enters the sleep mode, the second network component is controlled to enter the working mode and is transmitted to the SIM card holder, and whether the type of the SIM card is a preset type is judged, if yes, the second network component registers the network corresponding to the preset type, and if not, the second network component exits the working mode.
When the first network component enters the sleep mode, the first network component sends a trigger signal to the second network component so that the second network component enters the working mode. The second network component is transmitted to the SIM card seat after entering the working mode. Transparent transmission, i.e. pass-through, refers to the fact that in communication, no matter what the traffic content is transmitted, it is only responsible for transmitting the content of the transmission from the source address to the destination address without any change to the traffic data content. The second network component is transmitted to the SIM card holder, and judges whether the type of the SIM card inserted in the SIM card holder is a preset type, where the preset type refers to a network system that is preset to be supportable by the second network component, and the network system is a network type, for example, may be a network system of a mobile phone, such as: CDMA, GSM, WCDMA, 3G, 4GTD LTE, etc.
In one embodiment, as shown in fig. 4, the single-card multimode switching method further includes:
step 402, when the second network component exits the working mode, the first network component is controlled to switch from the sleep mode to the wake mode, and whether the SIM card is a narrowband Internet of things card is judged again,
step 404, if the SIM card is a narrowband internet of things card, the first network component registers a narrowband internet of things network,
step 406, if the SIM card is not a narrowband internet of things card, the first network component feeds back a registration network failure signal to the SIM card holder and enters a standby mode.
When the first network component is started and does not detect the SIM card supporting the narrowband Internet of things, the first network component enters a dormant mode, the single-card multimode module is switched to the second network component, and if the second network component fails to detect the SIM card of the preset type, the second network component cannot register to the network, and then the second network component is shut down. When the second network component exits the working mode, the first network component is awakened, enters the awakening mode and resumes normal operation, and the second network component is in a shutdown state. After the first network component enters the wake-up mode again, whether the SIM card is a narrowband internet of things card or not can be judged again, if the SIM card is a narrowband internet of things card, the first judgment is wrong, and the first network component registers the narrowband internet of things. If the SIM card is not the narrow-band Internet of things card, the first network component feeds back a registration network failure signal to the SIM card seat and enters a standby mode, wherein the registration network failure signal is used for identifying a network system of the SIM card which is not supported by the first network component and the second network component.
It should be understood that, although the steps in the flowcharts of fig. 3 and 4 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 3 and 4 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the sub-steps or stages are performed necessarily occur in sequence, but may be performed alternately or alternately with at least a portion of the other steps or sub-steps of other steps.
A single-card multimode switching method controls a first network component to judge whether the SIM card is a narrowband Internet of things card or not in an awakening mode: if the SIM card is a narrowband Internet of things card, the first network component registers a narrowband Internet of things network, and if the SIM card is not the narrowband Internet of things card, the first network component enters a sleep mode; and controlling a second network component to enter a working mode and pass through to the SIM card seat when the first network component enters a sleep mode, judging whether the type of the SIM card is a preset type, if so, registering a network corresponding to the preset type by the second network component, and if not, exiting the working mode by the second network component. The second network component is transmitted to the SIM card seat through the first network component, and single-card multimode switching is performed when the first network component enters the sleep mode, so that switching of a plurality of network modes can be accurately and efficiently realized, and user experience is improved.
