Description

T card detection method and mobile terminal

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a T card detection method and a mobile terminal.

Background

With the development of mobile terminal technology, a T-Flash card (also called microSD) is widely used in terminal devices such as mobile phones as a storage device. However, the T-card seat of the intermediate connector for communication between the T-card and the mobile phone occupies a large space, which seriously affects the layout of a PCB (Printed Circuit Board) motherboard of the mobile phone, so the industry generally integrates the T-card seat and the SIM-card seat together, designs to share the same card seat, and integrates the SIM-card (subscriber identity Module) and the T-card into one, which becomes a structural form of one-to-three, three-to-three, and the like.

Because the T-card and the SIM card are plug-in peripheral configuration components that can be replaced by the user, the system needs to detect whether the card is inserted in the mobile phone, and starts working when detecting that the card is present, and stops working when the card is absent.

At present, a detection mechanism for detecting whether a card exists is shown in fig. 1, because the T card and the SIM card have different working mechanisms, and T card detection consumes very much power, the T card does not perform polling detection in the industry, and only relies on data of an interrupt pin as a basis for determining whether the T card exists, however, when an interrupt is not triggered due to a mechanical fault, the T card cannot obtain a signal prompt of the interrupt pin, so that a problem that the T card still displays a working state (shown by a dotted line in fig. 1) occurs.

Therefore, in the conventional T card detection scheme, if a failure occurs during card pulling to cause a failure in triggering interruption, the T card is already pulled out, but the system still falsely displays the problem of the T card, so that the T card is inconvenient to use by a user, and the user experience is very poor.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 2, a flowchart of a T card detection method according to a first embodiment of the present invention is shown, which may specifically include the following steps:

s201, obtaining a diagnosis signal sent by the SIM card subsystem, wherein the diagnosis signal is sent when the SIM card subsystem does not receive a card reading response.

In the embodiment of the invention, the diagnostic signal from the SIM card subsystem is acquired through the T card subsystem. In order to ensure that the SIM card is held on line continuously, real-time information interaction can be carried out between the SIM card and the SIM card clip system. When the SIM card is disconnected, the SIM card system sends a card reading request to the SIM card, and if the card reading response is not received, the T card subsystem receives a corresponding diagnosis signal.

S202, detecting the T card according to the diagnosis signal.

In the embodiment of the invention, the T card subsystem can know that the SIM card system can not read the data in the SIM card according to the received diagnosis signal, so that the T card subsystem is triggered to detect the T card according to the diagnosis signal.

S203, determining to display the existence of the T card or display the removal of the T card according to the detection result of the T card.

In the embodiment of the invention, after the T card is detected by the T card subsystem, a corresponding detection result is generated, and different detection results correspond to the information of the existence of different T cards. According to the detection result, the T-card subsystem can judge whether the T-card is removed or not and correspondingly display that the T-card exists or that the T-card is removed.

In the embodiment of the invention, the diagnosis signal of the SIM card is sent to the T card subsystem, so that the misinformation caused by mechanical faults is avoided, the accuracy and reliability of the display information of the T card are ensured, and the use experience effect of a user is improved.

Example two

Referring to fig. 3, a flowchart of a T card detection method according to a second embodiment of the present invention is shown, which specifically includes the following steps:

s301, determining whether information interaction between the SIM card subsystem and the SIM card is invalid or not through the SIM card subsystem according to a first time interval. If not, go to step S302; if it is invalid, the process proceeds to step S303.

In the embodiment of the invention, before the diagnostic signal sent by the SIM card subsystem is acquired, the SIM card subsystem determines whether the real-time information interaction between the SIM card subsystem and the SIM card is still effective according to the first time interval of once interaction every 28 seconds.

For a more clear description of the embodiments of the present invention, reference is made to fig. 4 for a detailed description. For the SIM card in work, when the SIM card needs to be pulled out, under the normal condition, the card support triggers the interrupt pin, the level of the interrupt pin is changed from low to high (or from high to low), and the system repeatedly reads data of about 2 seconds for the SIM card so as to judge that the SIM card is powered off. When the fault causes no trigger interrupt, step S401 is performed, and the SIM card first recognizes that the information interaction is invalid due to the card pulling action (because the SIM card always performs data interaction in real time, the card pulling causes the SIM card to be disconnected from the system, and the information interaction cannot be performed).

S302, if the information interaction between the SIM card subsystem and the SIM card is not invalid, no processing is carried out, and the normal communication between the SIM card subsystem and the SIM card is kept.

And S303, if the information interaction between the SIM card subsystem and the SIM card is invalid, sending a second card reading request to the SIM card through the SIM card subsystem according to a second time interval.

In the embodiment of the invention, if the real-time information interaction between the SIM card subsystem and the SIM card fails, the terminal operating system considers that the SIM card is disconnected, but cannot accurately judge whether the SIM card is still in the card slot, because the card is possibly pulled out and the interruption is not successfully triggered due to mechanical failure, or the card is not pulled out at all when the card is blocked and the interruption is not triggered. Therefore, the SIM card subsystem sends a second card reading request to the SIM card according to a second time interval of reading the card once in 1 second, and confirms whether the SIM card still exists according to whether a second response is received or not. Referring to fig. 4, when the SIM card real-time information interaction fails, step S402 is performed, the system performs the card searching again, the specific process of the card searching is as described in step S303, and step S304 is performed after the second card reading request is sent.

S304, if the number of times that the SIM card subsystem does not receive the second response reaches a set threshold, sending a diagnosis signal to the T card subsystem, and not sending the diagnosis signal until the SIM card subsystem receives the second response next time.

In the embodiment of the invention, when the SIM card subsystem does not receive the second response, the SIM card is considered to be pulled out, and in order to confirm whether the T card still exists, a diagnostic signal corresponding to the card reading failure result needs to be sent to the T card subsystem to detect the T card. If the diagnostic signal is not sent to the T-card system, the T-card presence may still be falsely indicated if the card holder has indeed been pulled out but the T-card system does not know this information. When the SIM card subsystem sends the second card reading request, a corresponding threshold may be set for the number of times of receiving the second response, and the threshold is determined according to the hardware parameters, performance, and the like of the terminal, which is not limited in the present invention. When the number of times that the SIM card subsystem does not receive the second response reaches the set threshold, the SIM card is considered to be actually absent, and the information indicated by the diagnosis signal at the moment is the information that the SIM card is absent. The diagnostic signal is not sent until the SIM card subsystem receives the second response next time, because for the T card subsystem, the diagnostic signal does not need to be continuously received, unnecessary power consumption is increased, and the T card needs to be detected as long as the SIM card does not exist after the diagnostic signal is received once. Thus, it can be ensured that the detection of the T-card is completed with lower power consumption.

With reference to fig. 4, the detection mechanism for the SIM card and the T card when they are inserted is as follows: when the terminal does not have the SIM card, after a user executes card inserting operation, the card support triggers an interrupt pin, the level of the interrupt pin is changed from high to low and reported to the system, and at the moment, for the T card, if the system can read the T card information and judges that the T card is electrified to work, the existence of the T card is displayed; if the system cannot read the T card information, judging that the T card is not electrified and is not effectively inserted, and displaying that the T card is removed; for the SIM card, the system carries out repeated polling on the interrupt pin for about 2 seconds, if the interrupt is pulled up all the time, namely, the high level state is kept, the SIM card is not electrified, and the SIM card is not effectively inserted; if the interruption is pulled down all the time, namely the original high level is changed into the low level, the power-on work of the SIM card is indicated, and further, if the system can not read the data of the SIM card in 960 milliseconds, the power-off work of the SIM card is indicated, and the SIM card does not work. For the SIM card in work, when the SIM card needs to be pulled out, under normal conditions, the card support triggers an interrupt pin, the level of the interrupt pin is changed from low to high, and the system carries out repeated data reading on the SIM card for about 2 seconds so as to judge that the SIM card is powered off;

when no trigger interrupt occurs due to a mechanical failure, as in step S401, the SIM real-time information interaction fails (because the SIM card always performs data interaction in real time, and the SIM card is disconnected from the system due to card pulling, so that information interaction cannot be performed), and then as in step S402, the system searches for the card again. After the system finishes finding the card, if data is returned in step S403, a conclusion that the SIM card is powered off is obtained; it is also possible that if no data is returned as in step S404, not only the SIM card is not present, but also step S405 is executed, where a diagnostic signal sent by the SIM card subsystem is received by the T card subsystem. After the SIM card subsystem sends the diagnostic signal, step S304 is performed, and the process proceeds to step S305.

S305, obtaining a diagnosis signal sent by the SIM card subsystem, wherein the diagnosis signal is sent when the SIM card subsystem does not receive a card reading response.

In the embodiment of the invention, the diagnostic signal from the SIM card subsystem is acquired through the T card subsystem. In order to ensure that the SIM card is held on line continuously, real-time information interaction can be carried out between the SIM card and the SIM card clip system. When the SIM card is disconnected, the SIM card system sends a card reading request to the SIM card, and if the card reading response is not received, the T card subsystem receives a corresponding diagnosis signal. Step S306 is further performed according to the diagnosis signal.

S306, sending a first card reading request to the T card through the T card sub-system according to the diagnosis signal.

In the embodiment of the invention, the T card subsystem can know that the SIM card system can not read the data in the SIM card according to the received diagnosis signal, so that the T card subsystem is triggered to send a first card reading request to the T card according to the diagnosis signal to read the data of the T card so as to detect the T card.

With reference to fig. 4, after receiving the diagnostic signal, the T-card subsystem proceeds to step S306, and performs information interaction on the T-card, where the specific information interaction process is referred to as S306, and according to the result of the information interaction, the contents of step S307 or step S308 are respectively executed.

S307, if the T card subsystem receives a first response corresponding to the first card reading request, the T card is displayed to exist.

S308, if the T card sub-system does not receive the first response corresponding to the first card reading request, the T card is removed.

In the embodiment of the invention, after the T card system detects the T card, a corresponding detection result is generated, and according to the detection result, the T card system can judge whether the T card is removed and display correspondingly. And if the T card subsystem receives a first response corresponding to the first card reading request, the T card is considered to exist, response data can be returned, and at the moment, the existence of the T card is displayed. If the T-card subsystem does not receive the first response, the T-card is not considered to exist, and response data cannot be returned, and at the moment, the information that the T-card is removed is displayed.

Referring to fig. 4, in step S407, if the T card data is normal, it indicates that the T card reading by the T card subsystem is successful, and accordingly, in step S408, the system displays that the T card exists; in step S409, if no data is returned from the T-card, it indicates that the T-card reading by the T-card subsystem failed, and accordingly, in step S410, the system displays that the T-card is removed.

In the T card detection process, the SIM card system and the T card system are subsystems belonging to an operating system of the mobile terminal, and the SIM card system and the T card system are uniformly coordinated and managed by the operating system, so that when the information interaction of the SIM card fails, a corresponding diagnosis signal is transmitted to the T card system to detect the T card, the system resource is effectively saved, and the power consumption of the T card detection is further reduced.

In the embodiment of the invention, the diagnosis signal of the SIM card is sent to the T-card holder system, the diagnosis signal triggers the T-card holder system to read the card at one time instead of frequently detecting the SIM card by using a polling means, so that the T-card is detected with low power consumption, in addition, false alarm caused by mechanical failure is avoided, the accuracy and reliability of the T-card display information are ensured, and the use experience effect of a user is improved.
