Description

Data acquisition method and terminal equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a data acquisition method and a terminal device.

Background

With the rapid development of the terminal market, the product updating speed is faster and faster, more and more terminal software problems are exposed, and the requirements of users on solving the software problems are higher and higher. Currently, terminals may address terminal software issues for users through online upgrade (OTA) techniques (e.g., HOTA upgrades).

Taking HOTA as an example, during HOTA upgrades, the communication interface (Qualcommmessage interface, QMI) of the modem may need to be restarted. After the HOTA upgrade of the terminal is completed and the terminal is restarted, QMI may not be restored, so that the terminal cannot acquire the data of the subscriber identity module (subscriber identity module, SIM) card from the modem through QMI, that is, there is no data of the SIM card available to activate the cellular data service, thereby causing the user to be unable to normally use the cellular data for surfing.

Disclosure of Invention

The application provides a data acquisition method and terminal equipment, which are beneficial to improving the probability of acquiring the data of a SIM card, thereby being beneficial to solving the problem that the cellular data service cannot be activated after HOTA upgrading.

In a first aspect, the present application provides a data acquisition method, applied to a terminal device, where the method includes: after the system upgrading of the terminal equipment is finished and restarted, requesting to acquire data of a Subscriber Identity Module (SIM) card, wherein the data of the SIM card are used for activating cellular data service; in case that the data of the SIM card is not acquired, the acquisition of the data of the SIM card is re-requested before restarting the terminal device again.

In general, the terminal device may involve a restart of QMI during a system upgrade (e.g., HOTA upgrade). After the system upgrade of the terminal device is completed and restarted, QMI may not be completely restored, at which time there is a case that the acquisition fails if the terminal device acquires data of the SIM through the QMI request. After the data of the SIM card is failed to be acquired, the terminal equipment cannot activate the cellular data service, so that the user cannot use the cellular data to surf the internet.

Based on the technical scheme of the application, after the system upgrade is completed and restarted, if the data of the SIM card is not acquired, the terminal equipment can actively acquire the data of the SIM card before the user manually restarts the terminal equipment or before the terminal equipment automatically restarts the terminal equipment. Therefore, the method is favorable for re-acquiring the data of the SIM card under the condition that the user is not felt, improves the probability of acquiring the data of the SIM card, and solves the problem that the cellular data service cannot be activated after the HOTA is upgraded.

With reference to the first aspect, in certain implementations of the first aspect, the terminal device includes a radio interface layer (radio interface layer, RIL). Re-requesting the data of the SIM card, including: re-requesting to acquire the data of the SIM card through the RIL; or, based on the power-on and power-off operation of the SIM card, re-requesting to acquire the data of the SIM card.

The application provides two methods for re-acquiring the data of the SIM card. In the first method, the RIL requests the data of the SIM card from the modem again through QMI in case the data of the SIM card is not acquired. In the second method, the RIL instructs the SIM card to perform a power-on and power-off operation if no data of the SIM card is acquired. The data of the SIM card is re-requested from the modem through QMI based on the power-on and power-off operation of the SIM card.

The two modes can increase the times of re-acquiring the data of the SIM card, are simple in implementation mode, are beneficial to solving the abnormal problem in the process of activating the cellular data service without participation of the user, and improve the use experience of the user.

With reference to the first aspect, in certain implementations of the first aspect, the terminal device includes a RIL. Re-requesting the data of the SIM card, including: re-requesting to acquire the data of the SIM card through the RIL; in the case where the data of the SIM card is not acquired through the RIL, the acquisition of the data of the SIM card is re-requested based on the power-on and power-off operation of the SIM card.

In the application, the terminal equipment combines two methods for acquiring the data of the SIM card, firstly carries out the first method and then carries out the second method. The first method is simpler and more convenient, and the user does not feel the method. The two methods are combined and implemented, so that the probability of automatically acquiring the data of the SIM card is increased, and the problem that the cellular data service cannot be activated after the system is upgraded is solved.

With reference to the first aspect, in certain implementations of the first aspect, the terminal device includes a RIL. Re-requesting the data of the SIM card, including: re-requesting to acquire data of the SIM card based on the power-on and power-off operation of the SIM card; in the case that the data of the SIM card is not acquired based on the power-on and power-off operation of the SIM card, the data of the SIM card is re-requested to be acquired through the RIL.

In the application, the terminal equipment combines two methods for acquiring the data of the SIM card, firstly implements the second method and then implements the first method. Thus, the probability of acquiring the data of the SIM card is improved, and the problem that the cellular data service cannot be activated after the system is upgraded is solved.

With reference to the first aspect, in certain implementation manners of the first aspect, the re-requesting, by the RIL, to obtain data of the SIM card includes: before the RIL sends the error report instruction, the data of the SIM card is re-requested to be acquired through the RIL, and the error report instruction is used for indicating that the data of the SIM card is not acquired.

In the present application, if QMI is not restored, then RIL returns an error instruction to RIL after sending a request to acquire data of SIM card to modem through QMI, indicating failure to acquire data of SIM card. After the RIL receives the error report instruction, the RIL sends the error report instruction to the call service. Before the RIL receives the error report instruction to the RIL sends the error report instruction to the call service, the RIL may re-request to acquire the data of the SIM card. This is advantageous in order to avoid additional delays to the flow of activating the cellular data service.

With reference to the first aspect, in some implementations of the first aspect, the number of times of re-requesting to acquire data of the SIM card by the RIL does not exceed a preset threshold. This is advantageous in order to avoid that excessive number of retries have an impact on the normal flow of activating the cellular data service.

With reference to the first aspect, in certain implementations of the first aspect, the terminal device further includes a call service. Based on the power-on and power-off operation of the SIM card, re-requesting to acquire the data of the SIM card comprises the following steps: re-requesting the RIL for obtaining the data of the SIM card through a call service based on the powering-on and powering-off operation of the SIM card; and re-requesting to acquire the data of the SIM card through the RIL.

In the application, the power-on and power-off operation of the SIM card triggers the call service to send a request for acquiring the data of the SIM card to the RIL again, and then the RIL can send the request for acquiring the data of the SIM card to the modem through the QMI again based on the request, so that the retry frequency is increased, and the probability of acquiring the data of the SIM card is improved.

The 2D graphics engine is a drawing engine for 2D drawing.

The modems of different manufacturers of android platforms are quite different, and the problem to be solved by RIL is to adapt to modems of different manufacturers. In the android platform, the RIL is located between the application framework layer and the modem, and includes two parts, RIL Daemon (RILD) and Vendor RIL. Wherein the RILD initializes the Vendor RIL, manages all communications from the telephony service, and dispatches them to the Vendor RIL as a requested command (solicited commands). The Vendor RIL manages all communications with the radio hardware and is distributed to the RILD via unsolicited commands (un solicited commands).

HOTA upgrade is an online upgrade solution, can be applied to an android system, and can solve the problem of terminal software. However, through big data statistics, various software problems exist in the HOTA upgrading process, for example, most users encounter the problem that the data traffic cannot be normally used for surfing the internet after the HOTA upgrading.

Fig. 3 is a schematic flow chart of a method 300 of activating cellular data services. In general, the terminal device may involve updating a software configuration (modem software configuration, MBN) file of the modem during the HOTA upgrade, and after the HOTA upgrade is completed, the terminal device may restart, after which the terminal device may perform the steps of the method 300 to activate the cellular data service. The MBN file is an integrated package file containing a set of embedded file system (embedded file system, EFS), non-volatile storage (NV) parameters that are customized by a particular operator. Each operator will have a specific MBN file contained in the modem's code.

The method 300 involves internal interactions of the terminal device, and in particular interactions between the SIM card, the call service, the RIL, and the modem. The method 300 includes steps S301 to S306, which are as follows:

S301, the SIM card sends a broadcast message to the call service, where the broadcast message is used to indicate that the SIM card has been switched from a card-less state (absent) to an online (present) state. Accordingly, the call service receives the broadcast message.

In general, the card status of a SIM card may include a presence status (present), a card-off status (error), and a card-free status (absent). When the card state is in the on-line state, the terminal device can normally communicate through the SIM card. When the contact between the SIM card and the metal contact of the mobile phone is poor or the battery is loose, the state of the SIM card can be a card-falling state or a card-free state, and the SIM card is not available.

S302, the call service sends a request for acquiring the data of the SIM card to the RIL. Accordingly, the RIL receives the request to acquire the data of the SIM card.

The data of the SIM card comprises the following types:

(1) Fixedly stored data, which is written by the SIM card center before the terminal device is sold, includes an international mobile subscriber identity (international mobile subscriber identification number, IMSI), an authentication Key (KI), authentication and encryption algorithms, etc. The data of the part of the SIM card is important application data when the SIM card is started and the SIM card is added into an operator network.

Where IMSI is an identification number that is used to distinguish between unnecessary subscribers in a cellular network and is not repeated in all cellular networks. After the call service obtains the IMSI, the call service can analyze the information such as the card number, APN and the like of the SIM card according to the IMSI. The APN is a parameter which needs to be configured when the terminal equipment surfs the internet and is used for identifying the accessed service. The APNs of the same service for different operators are different, e.g. access to internet services, with APN for operator a being cmnet and APN for operator B being 3gnet.

After the call service acquires the APN, the call service can activate the cellular data service according to the APN, namely, establish the connection of the data service with the network side, so that uplink and downlink cellular data can be transmitted.

(2) SIM card dynamic data about the network, such as location area identification codes (location area identification, LAI), public telephone network codes to prohibit access, etc. The data of the part of the SIM card is dynamic application data of the SIM card when the operator network updates the position information.

(3) SIM card related service codes such as personal identification number (personal identification number, PIN), PIN Unlock Key (PUK), billing rate, etc.

(4) The telephone directory is provided as a modifiable memory module to the user for storing telephone numbers entered by the user at any time.

S303, RIL sends request for obtaining data of SIM card to modem through QMI. Accordingly, the modem receives the request to acquire the data of the SIM card.

It should be understood that QMI is an interface provided by baseband chip vendors for application layer to underlying modems to communicate. The call service access modem needs to pass RIL, which needs to read the data of the SIM card from the modem through QMI.

S304, the modem sends an error report instruction (error 38) to the RIL, wherein the error report instruction is used for indicating that the data of the SIM card is not acquired. Accordingly, the RIL receives the error-reporting instruction.

S305, RIL sends error report instruction to call service. Accordingly, the call service receives the error report instruction.

S306, the call service updates the card status of the SIM card to a loaded status.

It should be understood that although the call service does not acquire the data of the SIM card and cannot activate the cellular service data according to the APN in the data of the SIM card, the call service still continues to update the card status of the SIM card to the loading completion status. In the loading completion state, the call service can normally provide services such as call, access network and the like, but no cellular data is available after the access network.

In S304, the RIL receives the error report instruction from the modem, and indicates that the data of the SIM card is not acquired, which is because, in the HOTA upgrade process, if there is a protocol-related update in the upgrade process, the terminal device updates the relevant configuration of the MBN file, and because the MBN file is a software configuration file of the modem, the modem also needs to be restarted when updating the MBN file, and the interface of the modem also needs to be restarted, and the interface of the modem includes QMI. After the HOTA upgrade is restarted, if the QMI is not restored to normal at this time, the RIL cannot acquire the data of the SIM card through the QMI, which may also be understood as that the data of the SIM card read by the RIL is empty. Thus, the call service cannot normally load the data of the SIM card, the APN is empty, and the cellular data service cannot be activated, so that the problem that the user cannot use the cellular network to surf the internet is caused.

Fig. 4 is a schematic diagram of an icon of a cellular data service according to an embodiment of the present application.

As shown by a in fig. 4, is a schematic icon of a failure of activation of the cellular data service, and b in fig. 4 is a schematic icon of a successful activation of the cellular data service. Comparing the icons identified by the boxes in fig. 4, it can be seen that in the case of a failure in activation of the cellular data service, the status bar of the mobile phone does not indicate a flag for transmission of uplink and downlink data services. And in case of successful activation of the cellular data service, the status bar of the mobile phone displays a flag indicating transmission of the uplink and downlink data service.

As shown in b of fig. 4, the status bar of the mobile phone displays an icon of the cellular data service, that is, a flag indicating the transmission of the uplink and downlink data services.

Currently, when a user finds that cellular data cannot be used for surfing the internet after the user restarts the HOTA upgrade at the terminal device, the user can restart the terminal device to solve the problem. However, this method requires manual operation by the user, which affects the user experience.

In view of this, an embodiment of the present application provides a data acquisition method, in which a terminal device performs HOTA upgrade, and after updating an MBN file and restarting, the terminal device may add a retry mechanism in the process of acquiring data of a SIM card, and retry to acquire the data of the SIM card. Thus, the probability of acquiring the data of the SIM card is increased, and the success rate of activating the cellular data service is improved. In addition, the method does not need manual operation of a user, and the terminal equipment can automatically trigger a retry mechanism, so that the use experience of the user is improved.

The retry mechanism of the embodiment of the application comprises a scheme one: RIL retry protocol. In the first scheme, after the terminal device performs HOTA upgrade, updates the MBN file and restarts, the RIL sends a request for acquiring the data of the SIM card to the modem through QMI after receiving the request for acquiring the data of the SIM card sent by the call service. If the RIL does not acquire the data of the SIM card, the RIL initiates a re-query and sends a request for acquiring the data of the SIM card to the modem through the QMI.

The terminal device of the embodiment of the application can be a mobile phone or a tablet and other devices supporting a cellular board (a SIM card can be inserted).

Fig. 5 is a schematic flow chart of a data acquisition method 500 according to an embodiment of the present application. After the HOTA upgrade of the terminal device is completed and restarted, the terminal device may perform the steps of method 500. The steps of method 500 may be interactively performed by a SIM card, a call service, RIL, and a modem of the terminal device. The terminal device may have a structure as shown in fig. 1 and/or fig. 2, but embodiments of the present application are not limited thereto.

The method 500 includes S501 to S509, which specifically include the following steps:

s501, the SIM card sends a first broadcast message to the call service, where the first broadcast message is used to indicate that the SIM card has been switched from a card-less state to an on-line state. Accordingly, the call service receives the first broadcast message.

S502, the call service sends a request for acquiring the data of the SIM card to the RIL. Accordingly, the RIL receives the request to acquire the data of the SIM card.

The request for acquiring the data of the SIM card in this step is illustratively a get_imsi message. The description of the data of the SIM card may be referred to in the description of S302, and will not be repeated here.

S503, the RIL sends a request to acquire data of the SIM card to the modem through QMI. Accordingly, the modem receives the request to acquire the data of the SIM card.

The request for acquiring data of the SIM card in this step is illustratively a qcril_ uim _request_get_imsi message.

S504, the modem sends an error report instruction (error 38) to the RIL, wherein the error report instruction is used for indicating that the data of the SIM card is not acquired. Accordingly, the RIL receives the error-reporting instruction.

In this step, if the QMI interface does not return to normal after updating the MBN file and restarting the MBN file in the process of performing the HOTA upgrade, when the RIL requests the modem to acquire the data of the SIM card through the QMI, the modem returns an error report instruction to the RIL, indicating that the data of the SIM card cannot be acquired.

S505, RIL starts the retry mechanism to inquire the data of the SIM card again.

It should be noted that, after the RIL receives the error reporting instruction, a preset time period exists before the RIL sends the error reporting instruction to the call service, that is, the RIL will send the error reporting instruction to the call service after the RIL receives the error reporting instruction.

Optionally, the RIL may retry querying the data of the SIM card within the preset period of time, which is in favor of avoiding extra delay to the flow of activating the cellular data service, and reducing the impact to providing the normal service after the call service.

If the QMI returns to normal during the period from when the RIL receives the error report instruction to when the RIL transmits the error report instruction to the call service, the RIL may re-query the data of the SIM card through the QMI, and S506 is performed.

Optionally, the number of RIL re-requests to acquire the data of the SIM card does not exceed a preset threshold, which may be preconfigured by the developer.

The preset threshold is illustratively 2. If the RIL successfully queries the data of the SIM card upon the first re-query, the RIL stops the query and S506 is performed. If the RIL fails the first re-query, the modem returns an error-reporting instruction to the RIL. The RIL does not send an error report instruction to the call service after receiving the error report instruction, continues to perform the second re-query, and performs S506 when the re-query is successful in the second time. If the second inquiry also fails, the RIL sends an error report instruction to the call service.

S506, the modem sends the data of the SIM card to the RIL through QMI. Accordingly, the RIL receives the data of the SIM card.

S507, RIL sends SIM card data to the call service. Accordingly, the call service receives the data of the SIM card.

S508, the call service updates the state of the SIM card to be the loading completion state.

S509, the call service loads the data of the SIM card and activates the cellular data service. The data of the call service loading the SIM card may also be described as a card following operation performed by the call service, where the card following operation indicates that corresponding content is displayed on the user interface according to the data of the SIM card. For example, an APN acquired from data of a SIM card is displayed at an interface of a set-radio and a network-mobile network-APN of a mobile phone.

In this step, because the call service can obtain the data of the SIM card, the call service can analyze the APN according to the IMSI in the data of the SIM card, send a PDN data establishment request to the network side according to the APN, and after the connection establishment of the PDN data service is successful, the terminal device can transmit cellular data with the network side.

The above description of the solution for RIL retry in conjunction with fig. 5 uses the time from when the RIL receives the error report instruction to when the RIL sends the error report instruction to the call service to try to retrieve the data of the SIM card, which is beneficial to avoiding additional delay to the process of activating the cellular data service. The method is simple to realize, and improves the probability of acquiring the data of the SIM card, thereby being beneficial to solving the problem that the cellular data service cannot be activated after the HOTA is upgraded.

The retry mechanism of the embodiment of the application comprises a scheme II: RIL instructs the SIM card to power up and down. In the second scheme, after the terminal device performs HOTA upgrade, updates the MBN file and restarts, the RIL sends a request for acquiring the data of the SIM card to the modem through QMI after receiving the request for acquiring the data of the SIM card sent by the call service. If the RIL does not acquire the data of the SIM card, the RIL indicates the power-on and power-off operation of the SIM card so as to acquire the data of the SIM card again.

To avoid interference to the user caused by frequent power-on and power-off operations, the RIL typically instructs the SIM card to perform the power-on and power-off operation at most once.

Fig. 6 is a schematic flow chart of another data acquisition method 600 provided by an embodiment of the present application. After the end device system upgrade is completed and restarted, the end device may perform the steps of method 600. The steps of method 600 may be interactively performed by a SIM card, a call service, RIL, and a modem of the terminal device. The terminal device may have a structure as shown in fig. 1 and/or fig. 2, but embodiments of the present application are not limited thereto.

The method 600 includes S601 to S613, which specifically include the following steps:

s601, the SIM card sends a first broadcast message to the call service, wherein the first broadcast message is used for indicating that the SIM card is switched from a card-free state to an online state. Accordingly, the call service receives the first broadcast message.

It should be appreciated that the switching of the SIM card from the card-less state to the on-line state in this step is due to the completion of the HOTA upgrade of the terminal device and the restart. The restarting process of the terminal equipment involves starting up and then shutting down, the terminal equipment shuts down firstly, and the SIM card is in a card-free state after shutting down. And then the terminal equipment is started, and the card state of the SIM card is switched from the card-free state to the on-line state after the terminal equipment is started.

S602, the call service sends a request for acquiring the data of the SIM card to the RIL. Accordingly, the RIL receives the request to acquire the data of the SIM card.

S603, the RIL sends a request to acquire data of the SIM card to the modem through QMI. Accordingly, the modem receives the request to acquire the data of the SIM card.

S604, the modem sends an error report instruction to the RIL, wherein the error report instruction is used for indicating that the data of the SIM card is not acquired. Accordingly, the RIL receives the error-reporting instruction.

S601 to S604 are similar to S501 to S504, and are not repeated here.

Similar to the description for S504, the RIL may instruct the SIM card to perform a power-on/power-off operation within a preset duration after receiving the error-reporting instruction. The preset time length is a time length corresponding to the time period from when the RIL receives the error reporting instruction to when the RIL sends the error reporting instruction to the call service. If the RIL successfully acquires the data of the SIM card within the preset time length, the RIL does not send an error reporting instruction to the call service.

S605, the RIL sends a power-on and power-off instruction to the SIM card, and instructs the SIM card to execute the power-on and power-off operation once. Correspondingly, the SIM card receives the power-on and power-off instruction.

S606, the SIM card executes power-on and power-off operation.

The SIM card executes power-on and power-off operations, and the method comprises the following steps: the SIM card firstly sets the card state as a card-free state, and the power-off operation is executed when the SIM card sets the card-free state; and then the SIM card sets the card state as an on-line state, and the on-line state is the power-on operation.

S607, the SIM card sends a second broadcast message to the call service, where the second broadcast message is used to indicate that the SIM card has been switched from the card-less state to the online state. Accordingly, the call service receives the second broadcast message.

S608, the call service sends a request to the RIL to acquire the data of the SIM card. Accordingly, the RIL receives the request to acquire the data of the SIM card.

S609, the RIL sends a request to acquire data of the SIM card to the modem through QMI. Accordingly, the modem receives the request to acquire the data of the SIM card.

In the process that the SIM card performs a power-on and power-off operation once, the call service issues a request for acquiring the SIM card to the RIL again and the RIL requests the modem to acquire the SIM card again through the QMI, if the QMI has been restored to normal, S610 is performed.

S610, the modem sends the data of the SIM card to the RIL through QMI. Accordingly, the RIL receives the data of the SIM card.

S611, RIL sends the data of SIM card to the call service. Accordingly, the call service receives the data of the SIM card.

S612, the call service updates the state of the SIM card to be the loading completion state.

S613, the call service loads the data of the SIM card and activates the cellular data service.

The scheme of controlling the SIM card to perform the power-on and power-off operation by the RIL is described above in connection with fig. 6, and the scheme utilizes the time from the RIL receiving the error-reporting instruction to the RIL sending the error-reporting instruction to the call service to reinitiate a request for obtaining the data of the SIM card through the power-on and power-off operation of the SIM card, without the need of manually restarting the terminal device by the user to perform the power-on and power-off operation of the SIM card, thereby being beneficial to reducing the user operation and improving the probability of obtaining the data of the SIM card, and being beneficial to solving the problem that the cellular data service cannot be activated after the HOTA is upgraded.

The first and second embodiments described above may be implemented alone or in combination.

Fig. 7 is a schematic flow chart of yet another data acquisition method 700 provided in an embodiment of the present application, after the HOTA upgrade of the terminal device is completed and restarted, the terminal device may perform the steps of the method 700. The steps of method 700 may be interactively performed by a SIM card, a call service, RIL, and a modem of the terminal device. The terminal device may have a structure as shown in fig. 1 and/or fig. 2, but embodiments of the present application are not limited thereto.

The method 700 includes S701 to S715. S701 to S705 are similar to S501 to S505, and will not be described here again. In S706, the RIL determines that the data of the SIM card is not queried, at which time the QMI may still not be restored, so the RIL still cannot acquire the data of the SIM card from the modem through the QMI. The RIL determines that the data of the SIM card is not queried, including: the RIL receives an error command from the modem to determine that the data of the SIM card was not queried. In this case, the RIL performs S707 to instruct the SIM card to perform a power-on and power-off operation once. S707 to S715 are similar to S605 to S613, and are not described here.

In the embodiment of the application, the terminal equipment combines the scheme I and the scheme II, and in the scene that the terminal equipment updates the MBN file and restarts in the HOTA upgrading process, if the RIL does not acquire the data of the SIM card, the RIL firstly acquires the data of the SIM card. If the data of the SIM card is not obtained yet, the RIL instructs the SIM card to perform a power-on and power-off operation, so that the call service sends a request for obtaining the data of the SIM card once again to the RIL, and the RIL obtains the data of the SIM card from the modem again through the QMI. In the method, the terminal equipment can automatically perform the power-on and power-off operation of the SIM card under the condition that the retry mechanism is not effective, and the user does not need to manually restart the terminal equipment, so that the user can acquire the data of the SIM card under the condition of no sense, and the recovery of the cellular data service is finished.

The above description in connection with fig. 7 is that the terminal device executes scheme one first and then executes scheme two if scheme one fails. The terminal device may execute the second scheme first, and execute the first scheme when the second scheme fails.

Fig. 8 is a schematic flow chart of yet another data acquisition method 800 provided by an embodiment of the present application, after the HOTA upgrade of the terminal device is completed and restarted, the terminal device may perform the steps of the method 800. The steps of method 800 may be interactively performed by a SIM card, a call service, RIL, and a modem of the terminal device. The terminal device may have a structure as shown in fig. 1 and/or fig. 2, but embodiments of the present application are not limited thereto.

The method 800 includes S801 to S815. S801 to S809 are similar to S601 to S609, and are not described here. In S810, the modem sends an error report instruction to the RIL, where the error report instruction is used to indicate that the data of the SIM card is not acquired. Accordingly, the RIL receives the error-reporting instruction. S811 to S815 are similar to S505 to S509 and will not be described here again.

In the embodiments described in fig. 5 to 8, whether the RIL described in the first scheme requests to acquire the data of the SIM card from the modem through QMI again, or the RIL described in the second scheme instructs the SIM card to perform the power-on/power-off operation, so that the call service issues a request to acquire the data of the SIM card again, both methods are to retry to acquire the data of the SIM card. In the first scheme, the call service sends a request for acquiring the data of the SIM card to the RIL once, and the RIL performs an operation of re-querying the data of the SIM card. In the second method, the call service re-sends a request for acquiring the data of the SIM card to the RIL based on the power-on and power-off operation executed by the SIM card, and the RIL re-inquires the data of the SIM card.

To sum up, fig. 9 is a schematic flowchart of yet another data acquisition method 900 according to an embodiment of the present application. The steps of method 900 may be performed by a terminal device, which may have a structure as shown in fig. 1 and/or fig. 2, but embodiments of the present application are not limited thereto. The method 900 includes S901 and S902, and the specific steps are as follows:

s901, after the system upgrade of the terminal equipment is completed and restarted, the data of the SIM card is requested to be acquired and used for activating the cellular data service.

In this step, the system upgrade is illustratively an HOTA upgrade. The terminal device will automatically restart after the HOTA upgrade is completed. After the terminal device is restarted, the terminal device will request to acquire the data of the SIM card, which can be used to activate the cellular data service.

Specifically, the terminal device may analyze an APN according to an IMSI in data of the SIM card, where the APN is used to establish data connection with a network side to transmit uplink and downlink cellular data.

S902, when the data of the SIM card is not acquired, the data of the SIM card is re-requested to be acquired before restarting the terminal device again.

In this step, restarting the terminal device again means that the user manually restarts the terminal device. According to the technical scheme provided by the embodiment of the application, before the terminal equipment is manually restarted to acquire the data of the SIM card, the data of the SIM card is automatically requested again, so that a user is free from abnormal sense in the process of activating the cellular data service, the operation of the user is reduced, and the use experience of the user is improved.

The terminal equipment comprises a call service, RIL and a modem.

See, for example, the description of scheme two above in conjunction with fig. 6, which is not repeated here.

In another possible implementation manner, the terminal device re-requests to acquire the data of the SIM card, including: re-requesting to acquire the data of the SIM card through the RIL; in the case where the data of the SIM card is not acquired through the RIL, the acquisition of the data of the SIM card is re-requested based on the power-on and power-off operation of the SIM card. The description of the first execution scheme and the second execution scheme in conjunction with fig. 7 is specifically referred to above, and will not be repeated here.

In yet another possible implementation manner, the terminal device re-requests to acquire the data of the SIM card, including: re-requesting to acquire data of the SIM card based on the power-on and power-off operation of the SIM card; in the case that the data of the SIM card is not acquired based on the power-on and power-off operation of the SIM card, the data of the SIM card is re-requested to be acquired through the RIL.
