Embodiment 1

[0028] refer to figure 2 , shows a flow chart of a T card detection method in Embodiment 1 of the present invention, which may specifically include the following steps:

[0029] S201. Acquire a diagnostic signal sent by the SIM card subsystem, where the diagnostic signal is sent when the SIM card subsystem does not receive a card reading response.

[0030] In the embodiment of the present 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 continuously online, real-time information exchange will be performed between the SIM card and the SIM card subsystem. When the SIM card is disconnected, the SIM card system will send a card reading request to the SIM card. If no card reading response is received, the T card subsystem will receive the corresponding diagnostic signal at this time.

[0031] S202. Detect the T card according to the diagnosis signal.

[0032] In the embodiment of the p...

Embodiment 2

[0037] refer to image 3 , shows a flow chart of a T card detection method according to Embodiment 2 of the present invention, specifically comprising the following steps:

[0038] S301. Determine, by the SIM card subsystem, whether information interaction between the SIM card subsystem and the SIM card fails at a first time interval. If not, go to step S302; if not, go to step S303.

[0039] In the embodiment of the present invention, before obtaining the diagnostic signal sent by the SIM card subsystem, the SIM card subsystem will determine whether the real-time information interaction between the SIM card subsystem and the SIM card is still valid according to the first time interval of interaction every 28 seconds.

[0040] In order to describe the embodiment of the present invention more clearly, in combination with Figure 4 Describe in detail. For the working SIM card, when the card needs to be pulled out, under normal circumstances, the card tray triggers the interru...

Embodiment 3

[0060] refer to Figure 5 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0061] The mobile terminal 400 includes: a signal acquisition module 401 , a T card detection module 402 and a display module 403 .

[0062] A signal acquisition module 401, configured to acquire a diagnostic signal sent by the SIM card subsystem, wherein the diagnostic signal is sent when the SIM card subsystem does not receive a card reading response;

[0063] T card detection module 402, for detecting the T card according to the diagnostic signal;

[0064] The display module 403 is configured to determine to display that the T card exists or to display that the T card is removed according to the detection result of the T card.

[0065] refer to Image 6 , shows a structural block diagram of another mobile terminal according to Embodiment 3 of the present invention.

[0066] exist Figure 5 Optionally, the T-card detection module 402 ma...

Abstract

The embodiment of the invention provides a T card detection method and a mobile terminal, and relates to the technical field of mobile terminals. According to the embodiment of the invention, a diagnosis signal sent by an SIM card sub-system is obtained, wherein the diagnosis signal is sent when the SIM card sub-system does not receive card reading response; the T card is detected according to thediagnosis signal; and, according to a detection result on the T card, the fact that the T card exists is determined; or, the fact that the T card is removed is displayed. Thereby, presence or absenceinformation of the T card can be displayed more accurately; and thus, the use experience of users is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a T card detection method and a mobile terminal. Background technique [0002] With the development of mobile terminal technology, a T-Flash card (also known as microSD), as a storage device, is widely used in terminal devices such as mobile phones. However, the T card holder, the intermediate connection device between the T card and the mobile phone, takes up a lot of space, which seriously affects the layout of the PCB (Printed Circuit Board, printed circuit board) motherboard of the mobile phone. Therefore, the industry generally distinguishes the T card holder from the SIM card holder Integrated together, the design shares the same card holder, so that the SIM card (Subscriber Identification Module, user identification card) and the T card are combined into one, forming a structural form such as one for three, three for two.
