Fig. 1 is an application scenario diagram of a method for eliminating a SIM card firmware miscwitch in one embodiment. As shown in fig. 1, the application environment includes an electronic device 120 and a base station 140, and a communication connection is established between the electronic device 120 and the base station 140. The electronic equipment detects whether the IMSI of the access network in the SIM card is switched or not through a firmware switching service; if the IMSI of the access network is switched, judging whether the access state of the SIM card and the electronic equipment is changed or not through the firmware switching service; if the access state of the SIM card and the electronic equipment is not changed, the SIM card firmware switching flow is not triggered by the firmware switching service control. It is to be understood that the electronic device 140 may not be limited to various mobile phones, computers, portable devices, etc.
FIG. 2 is a flow chart of a method for eliminating a SIM card firmware miscorrection in one embodiment. The method for eliminating the miscwitch of the SIM card firmware in this embodiment is described by taking the electronic device in fig. 1 as an example. As shown in fig. 2, the method for eliminating the miscwitch of the SIM card firmware includes steps 220 to 260. Wherein,
step 220, detecting whether the IMSI of the access network in the SIM card is switched or not through the firmware switching service;
specifically, with the continuous development of network technologies, to meet the international roaming requirement of users, some operators have introduced one-card-multiple-number service, i.e. one SIM card corresponds to multiple IMSIs. The roaming IMSI list is preset in the SIM card, and the SIM card can judge whether to switch the IMSI according to the current position information of the electronic equipment, thereby completing the startup network selection flow.
However, for a SIM card with one card and multiple numbers, when roaming internationally, especially when the current network is unstable, frequent switching of the SIM card between different operator networks, i.e. frequent switching of the IMSI of the access network in the SIM card, will occur. If the default in the electronic device is that the IMSI of the access network in the SIM card is switched, it is considered that the SIM card is switched (for the electronic device supporting dual-card dual-standby or multi-card multi-standby), and the SIM card firmware switching process is triggered. Therefore, an unexpected SIM card firmware miscwitch event occurs, which seriously affects the stability of the system. In general, a type of SIM card corresponds to a firmware, for example, when a SIM1 belonging to a first operator accesses a network, the firmware corresponding to the first operator needs to be used; when the SIM2 belonging to the second operator accesses the network, firmware corresponding to the second operator needs to be used. Therefore, when the SIM card of the access network is switched, it is also required to switch to the firmware corresponding to the SIM card of the current access network.
Therefore, the application provides a method for eliminating the false switching of the SIM card firmware, and the electronic equipment detects whether the IMSI of the access network in the SIM card is switched or not through the firmware switching service. Among other things, firmware (FW) handover service (FW switch service) may be used to detect if a handover of IMSI of an access network in a SIM card occurs. Here, the access network refers to that the electronic device establishes a network connection with the base station through the SIM card.
Step 240, if the IMSI of the access network is switched, determining, by the firmware switching service, whether the access states of the SIM card and the electronic device are changed;
if the electronic equipment detects that the IMSI of the access network in the SIM card is not switched through the firmware switching service, the process of switching the firmware of the SIM card is not triggered at all. If the electronic device detects that the IMSI of the access network in the SIM card is switched through the firmware switching service, the access states of the SIM card and the electronic device may be changed at this time. Therefore, it is further required to determine whether the access state of the SIM card and the electronic device is changed by determining whether the access state of the SIM card and the electronic device is changed through the firmware switching service. Here, the firmware switching service may obtain the change information of the access states of the SIM card and the electronic device, so as to determine whether the access states of the SIM card and the electronic device are changed.
Step 260, if the access states of the SIM card and the electronic device are unchanged, the firmware switching process of the SIM card is not triggered by the firmware switching service control.
If the access state of the SIM card and the electronic equipment is not changed, the IMSI of the access network is switched, but the IMSI is switched only in the SIM card, and the access state of the SIM card and the electronic equipment is not really changed. I.e. the SIM card is still connected to the electronic device at this time, and then the firmware switching process of the SIM card is not triggered by the firmware switching service control. The method and the device avoid frequent misoperation of the SIM card firmware when the IMSI of the access network in the SIM card is only switched and the access state of the SIM card is not changed, thereby improving the stability of the system.
In the embodiment of the application, because in the electronic device, the SIM card firmware may need to be switched only when the SIM card switch occurs. However, if the default in the electronic device is that the IMSI of the access network in the SIM card is switched, the SIM card is considered to be switched, and the SIM card firmware switching process is triggered. Therefore, in the traditional method, if the IMSI of the access network is switched for one-card multi-number SIM card, the SIM card firmware switching flow is triggered, so that the SIM card firmware is frequently switched by mistake, and the stability of the system is reduced. After detecting that the IMSI of the access network in the SIM card is switched, the step of judging whether the access state of the SIM card is changed or not is added, so that when the access state of the SIM card is not changed, the SIM card firmware switching flow is controlled not to be triggered. When the access state of the SIM card is not changed, the frequent misoperation of the SIM card firmware is avoided, so that the stability of the system is improved.
In one embodiment, as shown in fig. 3, after determining whether the access state of the SIM card and the electronic device is changed by the firmware switching service, the method includes:
step 270, if the access states of the SIM card and the electronic device change, determining whether the SIM card accessed to the network after the switching can share the same SIM card firmware with the SIM card before the switching;
step 280, if not, triggering the SIM card firmware switching process through the firmware switching service.
Specifically, in the electronic device, the SIM card firmware needs to be switched only when the SIM card is switched and the switched SIM card and the SIM card before the switching cannot be used for one SIM card firmware. Therefore, after judging that the access states of the SIM card and the electronic equipment are changed, the step of judging whether the SIM card of the access network after switching can share the same SIM card firmware with the SIM card before switching is added, and if not, the SIM card firmware switching flow is triggered by the firmware switching service. Because some SIM cards belonging to different operators can share the same SIM card firmware, while some operators cannot share the same SIM card firmware.
In the embodiment of the present application, after detecting that the IMSI of the access network in the SIM card is switched, a step of determining whether the access state of the SIM card is changed is added, if the access state of the SIM card and the electronic device is changed, a step of determining whether the SIM card of the access network after the switching can share the same SIM card firmware with the SIM card before the switching is added, and if not, the SIM card firmware switching process is triggered by the firmware switching service. Therefore, the SIM card firmware is ensured to be switched only when the SIM card is switched and the switched SIM card and the SIM card before the switching cannot be used for the same SIM card firmware. The operation of frequently carrying out error switching on the SIM card firmware is avoided, so that the stability of the system is improved.
In one embodiment, as shown in fig. 4, determining, by the firmware switching service, whether the access state of the SIM card and the electronic device is changed includes:
step 420, reading ICCID of SIM card in access state with the electronic device through firmware switching service;
step 440, judging whether the ICCID of the SIM card currently in an access state with the electronic equipment is consistent with the original ICCID prestored on the electronic equipment;
step 460, if the access states of the SIM card and the electronic device are consistent, the access states of the SIM card and the electronic device are unchanged;
if the access states of the SIM card and the electronic device are inconsistent, step 480.
Wherein each SIM card has a unique ICCID (Integrate circuit card identity, integrated circuit card identification code) that is cured in the SIM card, by means of which a different SIM card can be identified. And storing the ICCID of the SIM card which is currently in an access state with the electronic equipment in the electronic equipment as an original ICCID, and periodically updating the original ICCID.
Therefore, whether the IMSI of the access network in the SIM card is switched or not can be detected through the firmware switching service, and if the IMSI of the access network is switched, the ICCID of the SIM card which is in an access state with the electronic equipment currently is read through the firmware switching service. Judging whether the ICCID of the SIM card in the access state with the electronic equipment is consistent with the original ICCID stored in the electronic equipment.
If the access states of the SIM card and the electronic equipment are not changed, the SIM card firmware switching flow is not triggered through the firmware switching service control.
If the access states of the SIM card and the electronic equipment are inconsistent, the access states of the SIM card and the electronic equipment are changed. Judging whether the SIM card accessed to the network after switching can share the same SIM card firmware with the SIM card before switching; if not, triggering the SIM card firmware switching flow through the firmware switching service.
In the embodiment of the application, the ICCID of the SIM card currently in an access state with the electronic equipment is read through the firmware switching service, and whether the ICCID of the SIM card currently in the access state with the electronic equipment is consistent with the original ICCID prestored on the electronic equipment or not is judged; to determine whether the access state of the SIM card and the electronic device is changed. Therefore, whether the access state of the SIM card and the electronic equipment is changed can be accurately judged by comparing ICCIDs. Furthermore, when the access state of the SIM card is not changed, frequent misoperation of the SIM card firmware is avoided, and therefore stability of the system is improved.
In one embodiment, a method for eliminating a miscwitch of SIM card firmware is provided, further including:
When the electronic equipment is started, acquiring the ICCID of a SIM card which is currently in an access state with the electronic equipment as an original ICCID;
after the firmware connected to the SIM card is switched by the firmware switching service control, the original ICCID is updated based on the ICCID of the SIM card currently in an access state with the electronic device.
Specifically, when the electronic device is plugged with the SIM card and is powered on, the electronic device reads the ICCID of the SIM card currently in an access state with the electronic device and stores the ICCID as an original ICCID. And when the access states of the SIM card and the electronic equipment are changed and the fact that the SIM card of the access network after switching cannot share the same SIM card firmware with the SIM card before switching is judged, triggering the SIM card firmware switching flow through the firmware switching service. After the firmware connected to the SIM card is switched by the firmware switching service control, the original ICCID is updated based on the ICCID of the SIM card currently in an access state with the electronic device. In this way, regular updates of the original ICCID stored in the electronic device can be guaranteed.
In the embodiment of the application, when the electronic equipment is started, the ICCID of the SIM card which is in an access state with the electronic equipment at present is obtained as the original ICCID. After the firmware connected to the SIM card is switched by the firmware switching service control, the original ICCID is updated based on the ICCID of the SIM card currently in an access state with the electronic device. In this way, regular updates of the original ICCID stored in the electronic device can be guaranteed. And whether the access states of the SIM card and the electronic equipment are changed can be accurately judged by comparing ICCIDs. Furthermore, when the access state of the SIM card is not changed, frequent misoperation of the SIM card firmware is avoided, and therefore stability of the system is improved.
In one embodiment, as shown in fig. 5, determining, by the firmware switching service, whether the access state of the SIM card and the electronic device is changed includes:
step 520, reading the current SIM card up signal or SIM card down signal through the firmware switching service;
step 540, judging whether the current SIM card power-on signal or SIM card power-off signal is consistent with the original SIM card power-on signal or SIM card power-off signal stored in the electronic equipment in advance;
step 560, if the access states of the SIM card and the electronic equipment are not changed;
if the access states of the SIM card and the electronic device are inconsistent, step 580 is performed.
Specifically, when judging whether the access state of the SIM card and the electronic equipment is changed or not through the firmware switching service, the current SIM card power-on signal or the current SIM card power-off signal can be read through the firmware switching service; and judging whether the current SIM card upper electric signal or the current SIM card lower electric signal is consistent with the original SIM card upper electric signal or the SIM card lower electric signal stored in the electronic equipment.
The electronic equipment can detect whether the SIM card is powered on or powered off, and generates an SIM card power-on signal when the SIM card is powered on, wherein the SIM card power-on signal comprises an identification of the SIM card. And generating an SIM card down signal when the SIM is powered up, wherein the SIM card down signal comprises the identification of the SIM card. And the SIM card up signal and the SIM card down signal may be stored in the electronic device so that the firmware switching service may read the signals.
Therefore, the currently generated SIM card up-signal or SIM card down-signal is read through the firmware switching service; judging whether the current generated SIM card upper electric signal or SIM card lower electric signal is consistent with the original SIM card upper electric signal or SIM card lower electric signal stored in the electronic equipment in advance; and further judging whether the access state of the SIM card and the electronic equipment is changed.
In the embodiment of the application, whether the access state of the SIM card and the electronic equipment is changed can be accurately judged by comparing the currently generated SIM card upper electric signal or the currently generated SIM card lower electric signal with the original SIM card upper electric signal or the SIM card lower electric signal stored in the electronic equipment. Furthermore, when the access state of the SIM card is not changed, frequent misoperation of the SIM card firmware is avoided, and therefore stability of the system is improved.
In one embodiment, a method for eliminating a false switch of the SIM card firmware is provided, and the method further comprises the following steps of;
when the electronic equipment is started, acquiring the current SIM card upper electric signal or the current SIM card lower electric signal as the original SIM card upper electric signal or the original SIM card lower electric signal;
after the firmware connected with the SIM card is switched through the firmware switching service control, the original SIM card power-on signal or the SIM card power-off signal is updated according to the SIM card which is in an access state with the electronic equipment currently.
Specifically, when the electronic device inserts the SIM card and starts up, the electronic device reads the current generated SIM card up signal or SIM card down signal as the original SIM card up signal or SIM card down signal. And when the access states of the SIM card and the electronic equipment are changed and the fact that the SIM card of the access network after switching cannot share the same SIM card firmware with the SIM card before switching is judged, triggering the SIM card firmware switching flow through the firmware switching service. After the firmware connected with the SIM card is switched through the firmware switching service control, the original SIM card power-on signal or the SIM card power-off signal is updated according to the SIM card which is in an access state with the electronic equipment currently. Therefore, the original SIM card up-signal or SIM card down-signal stored in the electronic equipment can be updated regularly.
In the embodiment of the application, when the electronic device is started, the current SIM card upper electric signal or the current SIM card lower electric signal is obtained as the original SIM card upper electric signal or the original SIM card lower electric signal. After the firmware connected with the SIM card is switched through the firmware switching service control, the original SIM card power-on signal or the SIM card power-off signal is updated according to the SIM card which is in an access state with the electronic equipment currently. Therefore, the original SIM card up-signal or SIM card down-signal stored in the electronic equipment can be updated regularly. Therefore, whether the access state of the SIM card and the electronic equipment is changed can be accurately judged by comparing the current generated SIM card upper electric signal or the SIM card lower electric signal with the original SIM card upper electric signal or the SIM card lower electric signal stored in the electronic equipment. Furthermore, when the access state of the SIM card is not changed, frequent misoperation of the SIM card firmware is avoided, and therefore stability of the system is improved.
In one embodiment, as shown in fig. 6, step 220 of detecting, by the firmware switching service, whether the IMSI of the access network in the SIM card is switched, includes:
step 222, obtaining MCC or MNC corresponding to IMSI of the access network from the SIM card through the firmware switching service;
step 224, determining whether the MCC or MNC corresponding to the IMSI of the access network is consistent with the MCC or MNC corresponding to the IMSI of the access network at a time before the interval of the preset time period;
step 226, if the IMSI of the access network in the SIM card is detected to be not switched;
step 228, if the IMSIs in the access network in the SIM card are not consistent, it is detected that the IMSIs in the access network in the SIM card are switched.
Specifically, each SIM card has an IMSI identity therein, where the IMSI identity stores information such as country, operator, etc. to which the SIM card belongs. IMSI (International Mobile SubscriberIdentity ), which is a key to identify mobile subscribers, has a total length of not more than 15 digits, and uses digits of 0 to 9. IMSI consists of mcc+mnc+msin. MCC (Mobile Country Code) is the code number of the country to which the mobile phone number belongs, and occupies 3 places. The resources of MCC are uniformly allocated and managed by the international electrotechnical union, and chinese MCC is specified as 460. With MCC it is possible to distinguish from which country the user comes, so international roaming can be achieved. MNC (Mobile Network Code, mobile network number) for identifying the mobile network to which the mobile client belongs.
