Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

When the mobile phone performs the SIM card loading process, the APN creation process may be triggered when the SIM card information is not fully loaded, resulting in the failure of the APN creation and the mobile phone being unable to connect to the Internet. Based on this, embodiments of the present invention provide an APN creation method, device, and mobile terminal for a mobile terminal. The mobile terminal mentioned in the embodiments of the present invention may be a mobile phone, a tablet computer, a wearable terminal, or the like that is configured with a SIM card. For a mobile device, the following describes the embodiments of the present invention in detail.

Example 1:

Referring to the flowchart of a method for creating an APN of a mobile terminal shown in FIG. 1 , the method is described by taking the description from the framework working layer of the mobile terminal as an example, and includes the following steps:

Step S102, when the framework working layer of the mobile terminal receives the SIM card ready message, it starts the SIM card loading process.

The SIM card in this embodiment may be a telecommunication card, or may be a mobile card, a China Unicom card, or the like, which is not limited in this embodiment of the present invention.

The above-mentioned SIM card readiness message can be sent to the framework working layer by the modem of the mobile terminal, that is, when the modem (modem) of the mobile terminal identifies that the current SIM card has an update event, it sends the SIM card to the framework working layer of the mobile terminal. Card ready message (EVENT_SIM_READY message).

The above-mentioned update event of the SIM card may include at least one of the following: an update event triggered by re-insertion of the SIM card, an update event triggered by SIM card information update, and an update event generated when the mobile terminal is roaming.

Re-inserting the SIM card includes not only inserting and removing the SIM card in the off state, but also inserting and removing the SIM card in the on state (hot swapping). For the inserting and removing the SIM card in the off state, the update event triggered by the re-insertion of the SIM card may include: After the power is turned on, it is determined by detecting the update event that the SIM has a plug-in event in the power-off state, for example, by detecting a certain identifier of the update event.

The update event triggered by the SIM card information update usually includes the update event issued by the operator. For example, if the user subscribes to a new service (such as activating the 4G service), the operator will send the update event to the mobile terminal. According to the update event It can be determined that there is a SIM card information update.

The update event generated when the mobile terminal is roaming usually includes network switching (lease) during roaming, etc. In this scenario, an update event will also be generated. Based on the update event, it can be determined that the mobile terminal belongs to the roaming scenario. Status or information update, The SIM card information also needs to be reloaded.

After receiving the EVENT_SIM_READY message, the framework working layer will start the SIM card loading process.

Step S104 , when the framework working layer receives a notification event triggered by the loading process that the card record has been loaded, it registers the card record loading completion notification event for the loading process.

In this embodiment, when the framework working layer receives a card record loaded notification event (for example: EVENT_RECORDS_LOADED), the framework working layer does not directly trigger the APN creation process, but registers a card record loading completion notification event for the loading process ( For example: EVENT_SIM_RECORDS_LOADED), so that when all the SIM information is loaded in the loading process, EVENT_SIM_RECORDS_LOADED is fed back to the framework working layer to inform the framework working layer that the SIM information is all loaded.

Step S106, when the framework working layer receives the notification event of the loading completion of the card record triggered by the loading process, the APN creation process is triggered, so that the APN creation process uses the loaded SIM card information to create an APN.

When receiving EVENT_SIM_RECORDS_LOADED triggered by the loading process, the framework working layer can confirm that the loading process has loaded all the SIM information, thereby triggering the APN creation process and ensuring the integrity of the SIM card information used by the APN creation process.

In the above method of this embodiment, when the framework working layer starts the SIM card loading process and receives the notification event that the card record has been loaded, it no longer directly triggers the APN creation process, but registers a card record loading completion notification for the loading process. Event, the card record loading completion notification event will be sent to the framework working layer by the loading process when the SIM information is loaded, so that the framework working layer will trigger the APN creation process when it receives the card record loading completion notification event. Ensure that the SIM card information used in the APN creation process is the complete information of the SIM card, avoid the abnormal APN creation caused by incomplete loading of the SIM card information (such as IMSI, MCC or MNC), thereby improving the reliability of the mobile terminal's network access, The user experience of using the mobile terminal is improved.

Embodiment 2:

Based on the method for creating an APN of a mobile terminal provided in the first embodiment above, referring to the flowchart of another method for creating an APN of a mobile terminal shown in FIG. 2 , the method specifically includes the following steps:

Step S202, when the framework working layer of the mobile terminal receives the SIM card ready message, it starts the SIM card loading process.

Step S204, when the framework working layer receives the notification event triggered by the loading process that the card record has been loaded, it determines whether the SIM card record object exists; if so, executes step S206, and if not, ends the process.

Considering that the user may suddenly pull out the card during the loading process of the mobile phone, in order to improve the reliability of APN creation, when the framework working layer receives EVENT_RECORDS_LOADED, it can judge whether the SIM card exists by judging whether the SIM card record object (mSimRecords) exists. If it exists, when it is determined that mSimRecords exists, the subsequent process is performed. The recording object of the SIM card may include various information about the SIM, such as the identity of the SIM card, operator information, short message information, and the like.

Step S206 , record the loading completion notification event for the loading process registration card, which is EVENT_SIM_RECORDS_LOADED in this embodiment.

Step S208, when the framework working layer receives the notification event of the loading completion of the card record triggered by the loading process, it triggers the APN creation process, so that the APN creation process uses the loaded SIM card information to create an APN.

In order to prevent the information in the loading process from occupying the storage space of the mobile terminal all the time, the above method is further optimized in this embodiment, and the following steps S210 and S212 are added.

In step S210, it is judged whether the recording object of the SIM card exists; if so, step S212 is executed; if not, the process ends.

When the above SIM card is always installed on the mobile terminal, the record object of the SIM card will exist, and when the SIM card is pulled out, the record object of the SIM card will not exist. Based on this, the information added during the loading process is cleared. Before, you can first check whether the recording object of the SIM card exists, and if it does not exist, you can directly end the process.

Step S212, delete the card record loading completion notification event, and clear the record object of the SIM card.

The deletion of the card record loading completion notification event is the opposite operation of registering the card record loading completion notification event for the loading process in step S206, which may also be referred to as deregistering the card record loading completion notification event.

In the above-mentioned method of this embodiment, the existence of the recording object of the SIM card is judged twice, and when it is judged for the first time that the recording object of the SIM card exists, the loading process is registered to record the loading completion notification event. The event will be sent to the framework working layer by the loading process when the SIM information is loaded, so that the framework working layer will trigger the APN creation process when it receives the notification event to ensure the reliability of the APN creation process execution. When it is judged for the second time that the record object of the SIM card exists, the card record upload notification event and the record object of the SIM card can be deleted, the storage space utilization rate of the mobile terminal is optimized, and the system operation performance of the mobile terminal is improved.

Embodiment three:

This embodiment provides a specific application scenario of the foregoing embodiments. Referring to FIG. 3 , a schematic diagram of a surfing process based on updating SIM card information is shown, wherein the framework working layer is represented by framework. The specific process is as follows:

Process 1: Blindly plug or unplug the SIM card or power on or update the card. That is, when the blind insertion and removal of the SIM card, power-on or card update is detected, a first signal (msg1) is sent to the next process to enter the next SIM card loading process. Specifically, when the user inserts the card and restarts the mobile phone, blindly inserts and unplugs the SIM card, updates the card information, or updates the international roaming of the mobile phone, the modem (modem) recognizes the SIM card, reports the EVENT_SIM_READY message to the framework, and the framework receives the EVENT_SIM_READY message, and enters process 2 to start the SIM card loading process.

Process 2: SIM card loading process, and then a second signal (msg2) is sent to the next process to enter the next card information notification process. Specifically, when the framework receives the EVENT_RECORDS_LOADED message, it enters process 3.

Process 3: the card information notification process, and then a third signal (msg3) is sent to the next process to enter the next APN creation process, that is, process 4.

Process 4: APN creation process, and then a fourth signal (msg4) is sent to the next process to enter the next data dialing process. In this process, the preferred APN can be obtained, and the preferred APN can be used for dialing, and the process 5 is entered.

Process 5: a data dialing process, and then a fourth signal (msg5) is sent to the next process to enter the next user Internet access process. At the end of the data dialing process, an IP address can be obtained and a data link can be established.

Process 6: The user goes online.

The above method simply describes the various processes that the mobile terminal goes through between monitoring that the user adopts the SIM card blind plugging or unplugging or booting or card updating, and the user goes online, and the above method adds a card information notification process between each process. , so as to ensure the normal execution of the APN creation process, thereby improving the reliability of the mobile terminal's network access, and improving the user experience of using the mobile terminal.

Based on the surfing process for updating SIM card information provided in FIG. 3 , the present embodiment further refines the card information notification process in process 3. Referring to the schematic diagram of a card information notification process shown in FIG. 4 , the process is specific include:

(1) Judge whether mSimRecords exists, if so, enter (2); if not, exit the card information notification module.

(2) mSimRecords registration notification EVENT_SIM_RECORDS_LOADED.

(3) onRecordsLoaded process; this process also creates APN.

(4) Determine whether mSimRecords exists, if so, enter (3); if not, exit the card information notification module.

(5) mSimRecords to register notification EVENT_SIM_RECORDS_LOADED.

(6) Clear mSimRecords, including clearing the mSimRecords object itself and the information loaded in the object.

In the card information notification process shown in Figure 4, when confirming the existence of mSimRecords (that is, the existence of the SIM card), mSimRecords needs to be registered once to notify EVENT_SIM_RECORDS_LOADED, so that after the SIM card information is completely loaded, the framework can receive the EVENT_SIM_RECORDS_LOADED event, determine The complete SIM card information such as MCC and MNC required in the APN creation process has been obtained, and then the APN creation process is triggered to ensure the normal creation of APNs and the normal establishment of data, and improve the reliability of mobile phone network access. Of course, deregistering to notify EVENT_SIM_RECORDS_LOADED and clearing mSimRecords can save the storage space of the mobile terminal and optimize the storage space utilization.
