As shown in fig. 2, the method steps include:
s1101, obtaining SIM card abnormal information sent by the modem, and judging whether the SIM card is in an abnormal card dropping state.
The modem is an important tool for interaction between the CPU or the terminal and the SIM card, and after the modem can acquire the information of the SIM card, a logic channel is established between the terminal and a network, networking data are transmitted, a communication mode is adjusted, and the like. The CPU is electrically connected with the modem directly or indirectly, so that the CPU can control or instruct the modem to monitor the working state of the SIM card or perform other operations. When the modem monitors that the working state of the SIM card is abnormal, the modem sends the abnormal information of the SIM card to the CPU at the first time, and the CPU obtains the abnormal information of the SIM card sent by the modem.
Optionally, due to a missing SIM card (for example, the SIM card is not installed in the terminal), a failure of the SIM card (for example, the SIM card cannot normally operate due to interference), or a failure of the modem (for example, a part of functions in the modem has a problem and cannot identify the SIM card), the modem may detect that the SIM card is in an abnormal state and send out abnormal information of the SIM card, so that after receiving the abnormal information of the SIM card, the CPU needs to determine whether the SIM card is in an abnormal card dropping state. The abnormal card dropping state refers to that the SIM card exists or works before the modem monitors that the SIM card is in the abnormal state and sends out abnormal information of the SIM card, namely, the SIM card is not in a missing state, and at the moment, the CPU determines that the SIM card is in the abnormal card dropping state.
The method for judging whether the SIM card is in the abnormal card dropping state may be that whether the SIM card is in the missing state is judged according to historical cache data of the SIM card in a preset time period, or a level state of each pin in the SIM card is detected, whether the SIM card is in the missing state is judged, or an SIM card switch is arranged in the card slot, after the SIM card enters the card slot, the SIM card switch is triggered, and then whether the SIM card is in the missing state can be judged by detecting the state of the SIM card switch, and only if the SIM card is determined not to be in the missing state, the CPU determines that the SIM card is in the abnormal card dropping state.
And S1102, if the SIM card is in an abnormal card dropping state, acquiring a card slot position corresponding to the abnormal SIM card.
When the SIM card is in the abnormal card dropping state, it is stated that the case that the SIM card is in the abnormal card dropping state due to the missing SIM card is eliminated, and therefore, the reason that the SIM card is in the abnormal card dropping state may be a SIM card failure (for example, the SIM card cannot normally operate due to interference) or a modem failure (for example, a part of functions in the modem fails to identify the SIM card). For example, when the SIM card is affected by interference and cannot work normally, for a terminal with multiple SIM cards, generally only a single SIM card is abnormal, the modem will detect that the SIM card is abnormal and send abnormal information of the SIM card, thereby causing the CPU to determine that the SIM card is in an abnormal card drop state, and when a part of functions in the modem is in trouble and cannot identify the SIM card, the modem will detect that all the SIM cards are abnormal and send abnormal information of the SIM card, thereby causing the CPU to determine that the SIM card is in an abnormal card drop state.
Because the SIM card corresponds to the card slot and the card slot position one by one, the number of the card slot positions is calculated by obtaining the card slot position corresponding to the abnormal SIM card, and whether the abnormal card dropping state of the SIM card is caused by the SIM card fault or the modem fault can be judged according to the number of the card slot positions. The mode of acquiring the slot position corresponding to the abnormal SIM card may be that the slot is numbered in advance, the slot number corresponding to the abnormal SIM card is obtained according to the abnormal information of the SIM card, and the slot number is used as the slot position corresponding to the abnormal SIM card; the card slot position corresponding to the abnormal SIM card can be judged according to the card slot identification carried in the abnormal SIM card information, and the mode of obtaining the card slot position corresponding to the abnormal SIM card is not limited in the application.
And S1103, if the number of the slot positions corresponding to the abnormal SIM cards is N and N is less than M, controlling the modem to execute a card detection process on the abnormal SIM cards in the N slot positions.
Optionally, if the number of the slot positions is N, and N is a positive integer smaller than M, it indicates that all the SIM cards are not abnormal, and it may be determined by the CPU that the SIM card is in an abnormal card drop state due to a SIM card failure (for example, the SIM card cannot normally operate due to interference). In general, when the SIM card cannot normally operate due to interference, it may be caused by internal timing or data confusion, and does not involve a structural or other substantial fault, so that the abnormal SIM card can be made to operate again by performing a card detection procedure on the SIM card.
Therefore, when the number of the card slot positions calculated by the CPU is N, a first reset instruction is sent to the modem, wherein the first reset instruction carries card slot numbers or card slot identifications corresponding to the N abnormal SIM cards. And after receiving the first reset instruction, the modem identifies the card slot number or the card slot identification after the first reset instruction, and executes card detection flow processing on the abnormal SIM card in the card slot position corresponding to the card slot number or the card slot identification. The process of executing the card detection on the SIM card may be to power on the abnormal SIM card, that is, to provide a reset level to a reset pin in the abnormal SIM card, and then sequentially reconfigure the SIM card according to preset configuration data, so as to implement the process of executing the card detection on the abnormal SIM card in the card slot position by the modem. After the SIM card is subjected to the card detection process, the abnormal SIM card can recover to work normally. After N SIM cards are abnormal, the card detection process is only executed on the N abnormal SIM cards, the use of other normal SIM cards is not influenced, and the use efficiency of the SIM cards is improved.
S1104, if the number of the slot positions corresponding to the abnormal SIM card is N and N is equal to M, executing a reset process on the modem.
Optionally, if the number of the slot positions is M, which represents that all the SIM cards in the terminal have a fault, it indicates that the CPU determines that the SIM card is in an abnormal card drop state due to a modem fault (for example, a part of functions in the modem have a problem and cannot identify the SIM card). Generally, when a part of functions in the modem are in trouble and the SIM card cannot be identified, the configuration in the modem may be wrong, and no structural or other substantial failure is involved, so that the modem can be made to work again by performing a reset procedure on the modem
Therefore, when the number of the card slot positions is calculated to be M by the CPU, a second reset instruction is sent to the modem. And after receiving the second reset instruction, the modem executes a reset process according to the second reset instruction and preset configuration data so as to reset the modem. After the modem executes the reset process, the modem can recover normal operation, and can identify and interact with the SIM card.
In the embodiment of the application, firstly, SIM card abnormal information sent by a modem is obtained, and whether the SIM card is in an abnormal card dropping state is judged; then judging whether the SIM card is in an abnormal card dropping state or not, and acquiring a card slot position corresponding to the abnormal SIM card; if the number of the card slot positions corresponding to the abnormal SIM card is N and N is less than M, the problem of the SIM card is shown, and the modem is controlled to execute a card detection process on the abnormal SIM card in the N card slot positions, so that the normal work of the SIM card can be recovered; or if the number of the card slot positions corresponding to the abnormal SIM card is N and N is equal to M, the problem of the modem is described, the normal work of the SIM card can be recovered by executing a reset process on the modem, and the quick processing of the abnormal SIM card falling is realized. When all the abnormal SIM cards are abnormal, the card detection process is only executed on the abnormal SIM cards, the use of other normal SIM cards is not influenced, and the use efficiency of the SIM cards is improved.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating an abnormal card dropping processing method according to another embodiment of the present application.
As shown in fig. 3, the method steps include:
s201, sending a monitoring instruction to the modem, wherein the monitoring instruction is used for indicating the modem to monitor the state of the SIM card, and when the modem monitors that the SIM card does not respond or communication time is out, determining that the SIM card is an abnormal SIM card and sending abnormal information of the SIM card.
Optionally, in order to implement real-time monitoring on the SIM card, so that the CPU can obtain the abnormal information of the SIM card in the first time after the SIM card is abnormal, the CPU sends a monitoring instruction to the modem when the terminal is restarted or the SIM card is reinserted, where the monitoring instruction is used to instruct the modem to monitor the state of the SIM card.
When the modem monitors that one or more SIM cards are abnormal, for example, the modem sends data to the SIM cards, but the SIM cards continuously do not return data, the modem judges that the SIM cards do not respond; or after the modem sends data to the SIM card, the modem receives the data returned by the SIM card after a long time, the communication timeout of the SIM card is judged, and the modem determines that the abnormal SIM card is the abnormal SIM card. And acquiring the card slot number of the abnormal SIM card according to the card slot number preset for each card slot, or acquiring the identifier of the abnormal SIM card according to the card slot identifier preset for each card slot, and generating the abnormal information of the SIM card, so that the abnormal information of the SIM card can carry the reason of the abnormal SIM card and the corresponding card slot number or card slot identifier, and the modem sends the abnormal information of the SIM card to the CPU.
S202, obtaining abnormal information of the SIM card sent by the modem, and obtaining historical cache data of the SIM card in a preset time period.
Because the SIM card is missing (the SIM card is not installed in the terminal or the SIM card is in poor contact with the card slot), the SIM card fails (for example, the SIM card cannot normally work due to interference) or the modem fails (the SIM card cannot be identified due to a problem in part of functions in the modem), the modem may send out abnormal information of the SIM card when monitoring that the SIM card is in an abnormal state, and therefore, after receiving the abnormal information of the SIM card, the CPU needs to determine whether the SIM card is in an abnormal card dropping state. The abnormal card dropping state refers to that the SIM card exists or works before the modem monitors that the SIM card is in the abnormal state and sends out abnormal information of the SIM card, namely, the SIM card is not in a missing state, and at the moment, the CPU determines that the SIM card is in the abnormal card dropping state.
Optionally, a feasible manner of determining whether the SIM card is in the missing state is to obtain historical cache data of the SIM card in a preset time period after obtaining the SIM card abnormal information sent by the modem. The SIM card may be in a preset time period before the time point when the CPU obtains the abnormal information of the SIM card, or may be in a preset time period before the time point when the modem detects the abnormal time point of the SIM card, where the preset time period may be set according to actual needs, for example, the preset time period may be 0.1 second or 1 second. The historical cache data can be obtained by the CPU directly from the memory, or can be obtained by the CPU from the modem, where the source of the historical cache data is not limited herein.
S203, judging whether the SIM card is in a missing state in a preset time period according to historical cache data of the SIM card in the preset time period.
It can be understood that the historical cache data of the SIM card in the preset time period may include interaction data of the SIM card with the network or with other integrated chips such as the CPU in the past time period, so that it may be determined from the cache data whether the SIM card is in a working state in the past time period, that is, whether the SIM card is in a missing state. For example, if data interacted between the SIM card and the external network exists in the cache data, it may be determined that the SIM card is in a working state within a past period of time, and thus it is determined that the SIM card is not in a missing state.
And S204, if the SIM card is not in the missing state within the preset time period, determining that the SIM card is in the abnormal card dropping state.
Because the modem detects that the SIM card is abnormal, if the SIM card is not in the missing state within the preset time period, it may be determined that the SIM card is in the abnormal state and sends out the abnormal information of the SIM card due to the fact that the modem detects that the SIM card is in the abnormal state (for example, the SIM card cannot normally operate due to interference) or the modem fails (the SIM card cannot be identified due to the problem of partial functions in the modem), and at this time, it may be determined that the SIM card is in the abnormal card dropping state. If the SIM card is in the missing state within the preset time period, it indicates that the SIM card is in the non-abnormal card missing state, for example, the SIM card is not inserted into the terminal, and at this time, the CPU controls the modem to continue to perform the step of monitoring the SIM card.
S205, acquiring a card slot number corresponding to the abnormal SIM card according to the abnormal information of the SIM card.
Alternatively, after the CPU determines that the SIM card is in the abnormal card dropping state, it indicates that the case that the SIM card is in the abnormal card dropping state due to the SIM card missing reason has been eliminated, and therefore, the reason that the SIM card is in the abnormal card dropping state may be a SIM card failure (for example, the SIM card cannot operate normally due to interference) or a modem failure (for example, a part of functions in the modem fails to identify the SIM card). For example, when the SIM cards are affected by interference and cannot work normally, for a terminal with multiple SIM cards, generally only one or several SIM cards are abnormal, and not all SIM cards are abnormal at the same time, at this time, the modem will monitor the abnormality of the SIM cards and send abnormal information of the SIM cards, so as to cause the CPU to determine that the SIM cards are in an abnormal card dropping state, and when a problem occurs in part of functions of the modem and cannot identify the SIM cards, the modem will detect that all the SIM cards are abnormal, and send abnormal information of the SIM cards at this time, so as to cause the CPU to determine that the SIM cards are in the abnormal card dropping state.
Because the SIM card corresponds to the card slot and the card slot position one by one, the number of the card slot positions is calculated by obtaining the card slot position corresponding to the abnormal SIM card, and whether the abnormal card dropping state of the SIM card is caused by the SIM card fault or the modem fault can be judged according to the number of the card slot positions. For example, when two SIM cards can be accommodated in the terminal, the number of the card slot is two, that is, M is two, the card slot number corresponding to one SIM card is 1, and the card slot number corresponding to the other SIM card is 2. For example, one kind of SIM card exception information is: the MMGSDI _ CARD _ ERR _ NO _ ATR _ RCVD _ AFTER _ RESET _ CARD1, wherein the character NO _ ATR _ RCVD represents that the reason of the SIM CARD with the abnormality is NO response, and the character CARD1 represents that the CARD slot number of the SIM CARD with the abnormality is 1, and then the CPU determines that the CARD slot number corresponding to the SIM CARD with the abnormality is 1 according to the SIM CARD abnormality information.
And S206, taking the card slot number corresponding to the abnormal SIM card as the card slot position corresponding to the abnormal SIM card.
Optionally, after obtaining the card slot number corresponding to the abnormal SIM card, the card slot number corresponding to the abnormal SIM card may be used as the card slot position corresponding to the abnormal SIM card, for example, when the card slot number of the abnormal SIM card is 1, the card slot position corresponding to the abnormal SIM card is also 1.

Generally, when a part of functions in the modem are in trouble and the SIM card cannot be identified, the configuration in the modem may be wrong, and no structural or other substantial failure is involved, so that the modem can be made to work again by performing a reset procedure on the modem
Therefore, when the number of the card slot positions is calculated to be N by the CPU and N is equal to M, a second reset instruction is sent to the modem. And after receiving the second reset instruction, the modem executes a reset process according to the second reset instruction and preset configuration data so as to reset the modem. After the modem executes the reset process, the modem can recover normal operation, and can identify and interact with the SIM card.
