At least one SIM card holder is usually disposed inside the current mobile phone for placing the SIM card. In the current mobile phone, if the external SIM card or the internal SIM card needs to be switched, the replacement needs to be performed manually, which is troublesome to operate. Therefore, the prior art cannot realize the automatic switching of the SIM cards.
In order to solve the problems, the technical idea of the invention is to configure the switching circuit on the terminal, and the terminal can correspondingly control the switching circuit to be connected with an external SIM card or an internal SIM card in the terminal by detecting a hot plug event or a hot plug event based on a determined event, so as to realize the automatic switching of the external SIM card and the internal SIM card, effectively improve the service capability of the terminal and meet the user requirements.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a scene schematic diagram of a SIM card switching control method according to an embodiment of the present invention, where an execution main body in the method according to the embodiment may be a terminal, and specifically may be a baseband processor modem on the terminal, where the modem may include units such as a digital signal processor DSP, a microcontroller MCU, and a memory. In order to realize the automatic switching of the SIM card, a switching circuit is arranged, wherein the switching circuit can be a GPIO switching circuit, the GPIO switching circuit is welded on the modem, a pin of the GPIO can be connected with the SIM card, and the modem can control the switching of the SIM connected with the switching circuit. The SIM card connected with the switching circuit can be powered on.
The terminal supports placing an external SIM card and configuring the internal SIM card, can be a single-card terminal (namely a modem with only one USIM interface) or a dual-card terminal, and for the single-card terminal, when the terminal is started by default, the external SIM card is electrified and initialized; for a dual-card terminal, when the terminal is powered on by default, the external SIM1 card (the SIM card placed in the main card slot) is powered on for initialization.
For example, taking a single-card terminal as an example, referring to fig. 1, hot plug detection for an external SIM card may be detected by a GPIO, and if a hot plug or hot plug event occurs in the single-card terminal, the GPIO switching circuit may be controlled to connect with a corresponding SIM card. For example, in a hot plug event, for example, the modem in fig. 1 is connected to the external SIM card, the external SIM card is powered on, and an initialization operation is performed, so as to complete network registration, thereby performing related services, implementing automatic switching between the external SIM card and the internal SIM card, effectively improving the service capability of the terminal, and meeting the user requirements.
For a dual-card terminal, a hot plug event exists, which may be similar to the steps executed by a single-card terminal, and is not described herein again.
Fig. 2 is a schematic flowchart of a SIM card switching control method according to an embodiment of the present invention. The SIM card switching control method is applied to a terminal, the terminal supports placing an external SIM card and configuring an internal SIM card, and for the convenience of understanding, the SIM card switching control method is explained in detail by taking a single-card terminal as an example. The SIM card switching control method may include:
s101, determining that the detected target event is a hot plug event or a hot plug event of the external SIM card.
In this embodiment, the terminal may detect, by the switching circuit, whether the target event is a hot plug event or a hot plug event of the external SIM card, where the hot plug event may be a hot plug into the external SIM card, and the hot plug event may be a hot plug out of the external SIM card.
Before detecting whether the target event is a hot plug event or a hot plug event of the external SIM card, the terminal may receive the target event, that is, the external SIM card hot plug event, through a Universal Subscriber Identity Module (USIM) in the terminal, which may specifically be implemented by the following steps:
step a1, receiving a target event through a global subscriber identity module in the terminal, where the target event is used to indicate a hot plug event of the external SIM card.
Step a2, if the SIM card switching function in the terminal is triggered to be enabled, determining to execute the operation of detecting that the target event is a hot-plug event or a hot-plug event of the external SIM card.
In this embodiment, the USIM module receives an external SIM card hot plug event, and reports the external SIM card hot plug event to the modem, and the modem starts to process the external SIM card hot plug event, and first determines whether the SIM card switching function is macro-closed, and if the macro-closed, the SIM switching is implemented in at least three scenarios:
and in a scene 11, if the USIM module receives a hot-plug event of the external SIM card under the condition of a card, executing an operation of activating the internal SIM card, and executing related work such as powering off the external SIM card.
And in the scene 12, if the USIM module receives the external SIM card hot plug event under the condition of no external SIM card, the USIM module executes the operation of activating the external SIM card to complete the related work of power-on initialization of the external SIM card.
Scene 13, and other cases are ended without executing the switching operation.
If the macro is not closed, the SIM card switching function in the terminal is triggered to enable, and the operation that the detection target event is the hot plug event or the hot plug event of the external SIM card is started to be executed, so that the specific detection of the target event is realized.
S102, if the target event is a hot plug event, controlling a switching circuit in the terminal to be connected with the external SIM card, so that the external SIM card is electrified to work.
In this embodiment, if the detected target event is a hot plug event, the modem controls the switching circuit to connect with the external SIM card, the external SIM card is powered on and initializes the external SIM card, and the terminal may register a network and perform related services only by using information related to the external SIM card.
S103, if the target event is a hot plug event, controlling a switching circuit to be connected with the built-in SIM card, so that the built-in SIM card is electrified to work.
In this embodiment, if the detected target event is a hot plug event, the modem controls the switching circuit to connect with the built-in SIM card, the built-in SIM card is powered on and initializes the built-in SIM card, and the terminal may register a network and perform related services only by using the related information of the built-in SIM card.
Specifically, the single-card terminal can alternately use the internal SIM card or the external SIM card, so as to meet the needs of the industry users, for example, the needs of the 5G industry users.
Therefore, for a Modem (2G/3G/4G/5G) (namely a single-card terminal) with only one USIM interface, aiming at the requirement of connecting two SIM cards for alternate use (namely, when an external SIM card is pulled out, the internal SIM card is automatically switched to the internal SIM card, the internal SIM card is powered on to work, and when the external SIM card is inserted in a hot mode, the external SIM card is automatically switched to the external SIM card and powered on to work), the single-card terminal can realize the user requirement and complete the automatic switching of the SIM cards by the SIM card switching control method.
The SIM card switching control method provided in this embodiment is applied to a terminal, where the terminal supports placing an external SIM card and configuring an internal SIM card; firstly, determining that a detected target event is a hot plug event or a hot plug event of the external SIM card; if the target event is a hot plug event, controlling a switching circuit to be connected with the external SIM card so that the external SIM card is electrified to work; if the target event is a hot-plug event, controlling the switching circuit to be connected with the built-in SIM card to electrify the built-in SIM card to work, and correspondingly controlling the switching circuit to be connected with the external SIM card and the built-in SIM card by the terminal based on the target event to realize the automatic switching of the external SIM card and the built-in SIM card, thereby effectively improving the service capability of the terminal and meeting the user requirements.
In a possible design, the present embodiment provides a detailed description of S101 on the basis of the above embodiments. The switching circuit is a GPIO switching circuit, and the GPIO switching circuit is used for being connected with the external SIM card or the internal SIM card. The determining that the detected target event is a hot-plug event or a hot-plug event of the external SIM card may be implemented by:
and b1, judging whether the external SIM card is pulled out when the terminal is in the card state by detecting the current state of the GPIO switching circuit.
Step b2, if the external SIM card is pulled out when the terminal is in the card state, determining that the operation is a hot pull event.
Step b3, if the external SIM card is not pulled out when the terminal is in the card-containing state, judging whether the external SIM card is inserted when the terminal is in the card-free state.
Step b4, if the external SIM card inserting operation exists when the terminal is in the no-card state, determining that the operation is a hot inserting event.
In this embodiment, the current state of the GPIO switching circuit is detected, for example, whether a pin of the GPIO is a high level or a low level, for example, the high level indicates that the external SIM card is pulled out under the condition of a card being present, and the low level indicates that the external SIM card is inserted under the condition of no card being present; or, the low level indicates that the external SIM card is pulled out in the case of a card being present, and the high level indicates that the external SIM card is inserted in the case of no card being present. The specific level state represents which kind of scene can be configured in advance, and no specific limitation is made here, and only by means of different level states, the external SIM card existing in the card-existing state is pulled out, and the external SIM card existing in the card-absent state is inserted and distinguished.
If a scene of the external SIM card pulling operation exists under the condition of card existence, determining that the external SIM card pulling operation is a hot pulling event; if the external SIM card is inserted into the external SIM card in the situation of no card, determining that the external SIM card is a hot insertion event; in other scenarios, the hot plug process may be directly ended, and the automatic switching and initialization operations of the SIM card may not be performed.
In a possible design, the present embodiment provides a detailed description of S102 on the basis of the above embodiments. The control switching circuit is connected with the external SIM card, so that the external SIM card is electrified to work, and the control switching circuit can be realized by the following steps:
and c1, controlling the GPIO switching circuit to be connected with the external SIM card, so that the external SIM card is powered on.
And c2, triggering the initialization operation of the external SIM card, and executing the operation of electrifying the external SIM card.
In this embodiment, the modem switches the GPIO to the external SIM card, that is, the external SIM card is powered on to operate, and then the modem triggers an initialization procedure of the external SIM card, so that the external SIM card completes initialization, and then the terminal can register a network by using relevant information of the external SIM card and perform relevant services.
