Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

Example one

As shown in fig. 1, the method of network connection includes:

step 101: when detecting that a system of the terminal equipment is in a first state, generating a network connection instruction; the first state represents that a system of the terminal equipment is in an abnormal working state or a state incapable of being started;

step 102: controlling the wireless communication unit to establish connection with the network side based on the network connection indication;

step 103: and performing data interaction with the network side based on the connection established between the wireless communication unit and the network side.

Here, the execution subject of steps 101 to 103 may be a processor of the terminal device.

In practical application, step 101 specifically includes: and when detecting that the android system cannot be normally started and cannot be recovered, generating a network connection indication. That is, the first state is a state in which the android system cannot be normally started and is unrecoverable. For example, when a system partition is abnormal, the android system cannot be started normally, the recovery mode cannot be recovered, and the WLAN cannot be used at this time.

In practical application, the data interaction with the network side specifically includes: downloading recovery data from a network side, wherein the recovery data is used for recovering a system of the terminal equipment so as to enable the system of the terminal equipment to be in a second state, and the second state represents that the system of the terminal equipment is in a normal starting state; or, uploading the key data to the network side.

That is to say, the data of the terminal device is backed up on the network side in advance, and after the system is connected to the network side in an abnormal state, the system can be restored to a normal state by downloading the previously backed-up data from the network side, or the key data of the terminal device is uploaded to the network side, so that the loss of the key data is avoided.

In practical applications, the wireless communication unit may be a wireless local area network WLAN.

Further, the step 102 of controlling the wireless communication unit to establish a connection with the network side includes: calling a binary program of a Linux end to start a WLAN minimum subsystem and establish connection with a network side; wherein the WLAN minimal subsystem comprises WLAN firmware and a WLAN network.

Further, invoking a Linux binary program to start a WLAN minimum subsystem, including: starting a binary program required by loading WLAN firmware and a binary program required by a WLAN network; initiating scanning through a wpa _ cli scan command and acquiring a scanning result; and accessing the destination network according to the scanning result.

Illustratively, accessing the destination network according to the scanning result includes: displaying the scanning result on a display interface; acquiring a network selection indication based on the displayed scanning result; and accessing the destination network according to the network selection indication.

Example two

To further illustrate the object of the present invention, based on the first embodiment of the present invention, as shown in fig. 2, the network connection method specifically includes:

step 201: when detecting that the android system cannot be started normally and cannot be recovered, generating a network connection instruction;

step 202: and calling a binary program of a Linux end to start a WLAN minimum subsystem according to the network connection instruction, and establishing connection with a network side.

Step 203: and downloading recovery data from the network side or uploading key data to the network side.

Illustratively, step 201 may specifically include: and when detecting that the android system cannot be normally started and cannot be recovered when entering a recovery mode, generating a network connection indication. Here, the recovery mode may be an android mobile phone backup function, and refers to a mode that can modify data or a system inside an android, and in this mode, an existing system may be backed up or upgraded, or factory settings may be restored here. For example, when a system partition of a mobile phone is abnormal, the system cannot be started normally, the recovery mode is entered and cannot be recovered, and a network connection indication is generated.

In actual application, the recovery data at least comprises data required by normal startup of the android system; and recovering the normal start of the android system according to the recovery data. For example, when a system partition is corrupted, the recovery data is the partition data that was previously backed up. The key data can be any data which needs to be protected when the system is abnormal by the terminal equipment. Such as address book, pictures, videos, documents, applications, etc. data for the user.

In practice, the WLAN minimal subsystem may include WLAN firmware and a WLAN network; invoking a Linux binary program to start a WLAN minimum subsystem comprises: starting a binary program required by loading WLAN firmware and a binary program required by a WLAN network; initiating scanning through a wpa _ cli scan command and acquiring a scanning result; and accessing the destination network according to the scanning result. Here, the Linux-side binary program may include: a wlan driver, a wpa _ suppernant (wlan management service process), a wpa _ cli (client calling process), and the like.

Further, invoking the Linux binary program to start the WLAN minimum subsystem may specifically include the following steps:

step a: starting basic binary service required by loading WLAN firmware; here, the base binary executable service is typically below the vendor/bin, running this process directly. Such as starting Hwservice manager, tftp _ server &, starting cns-daemon-n-l &, starting netd & etc.

Step b: loading WLAN network related services; here, invoke insmod/sbin/qca _ cld3_ WLAN. ko to load the WLAN driver, launch wpa _ suppernant and launch wpa _ cli.

Step c: initiating scanning to obtain a scanning result;

step d: and accessing the destination network according to the scanning result.

In the prior art, the use of the WLAN system can only be realized after the system is completely started, and a scene that the system is abnormally started and cannot be recovered cannot be covered, that is, the use of the WLAN system cannot be realized when the system is abnormally started and cannot be recovered. The technical scheme provided by the embodiment of the invention can ensure that the last remedial measure is taken when the android system cannot be normally started and recovered, the WLAN minimum subsystem is started to access the network, and the recovery data is downloaded from the network side or the key data is uploaded to the network side, so that the system is ensured to be recovered to be normal or the key information is not lost.

EXAMPLE III

The technical solution of the first embodiment of the present invention is further described in detail with reference to an application embodiment. When the system partition is abnormal and the system cannot be started normally, the control terminal device establishes connection with the network side, downloads the specified image file from the network side, or uploads the key data to the network side. The image file contains the partition data which is backed up previously, and the image file is analyzed after being downloaded, so that the damaged partition data is restored to the state before backup, and the system is normally started.

As shown in fig. 3, the network connection method specifically includes:

step 301: and generating a network connection indication when detecting that the android system cannot be started normally.

Here, step 301 may be executed by a processor of the terminal device, where the processor is capable of detecting whether the android system is normally started, and executing a normal system operation when the android system is normally started; when the normal starting cannot be carried out, a network connection instruction is generated; the processor of the terminal executes the steps of starting the WLAN minimum subsystem, i.e. executing steps 302 to 310, in the embodiment of the present invention when the network connection indication is detected.

Step 302: and mounting the subarea.

In the embodiment of the invention, the example that the system cannot be normally started due to the damage of the system partition is taken as an example for illustration, wherein when the system partition is abnormal, the system cannot be normally started, and the partition is possibly unloaded, so that the system, the vendor and the persistence partition can be normally mounted through a mount command, and then a Linux-end binary program is called to start the WLAN minimum subsystem.

Step 303: the basic binary services required to load the WLAN firmware are started.

Here, the WLAN firmware may be a hardware component included in the WLAN minimal subsystem, and the underlying binary executable service is usually under the vendor/bin, and this process may be run directly. Such as starting Hwservice manager, tftp _ server &, starting cns-daemon-n-l &, starting netd & etc.

Step 304: loading WLAN network related services.

Here, the WLAN network may be a software part included in the WLAN minimum subsystem, for example, invoking insmod/sbin/qca _ cld3_ wlan.ko to load a WLAN driver, and launching a wpa _ supplicant (WLAN management service process) and a wpa _ cli (client invocation process).

Step 305: initiating scanning, acquiring a scanning result, judging whether the scanning result exists, and if so, executing step 306; if not, execution continues with step 305.

Specifically, scanning is initiated through a wpa _ cli scan command, and a scanning result is obtained, wherein the scanning result comprises at least one access network. For example, the scanning result includes network 1 to network N, where N is a positive integer.

Step 306: and acquiring a network connection instruction according to the scanning result to determine the connected destination network.

Illustratively, the scanning result is displayed on a display interface for a user to select, the user selects a connected destination network from the scanning result, a network connection instruction is generated according to the selection result of the user, and then the connected destination network is determined according to the generated network connection instruction. For example, a user selects a network 1 from a network 1 to a network N as a destination network, and a terminal acquires a network connection indication of an access network 1; and determining the network 1 as a destination network according to the network connection indication.

Step 307: calling wap _ cli binary to connect to the destination network.

Specifically, a wpa _ cli set _ network command is called to connect to the network.

Step 308: the dhcptools program is called to assign IP addresses.

Specifically, the dhcptools wlan0 is invoked to negotiate an IP address with the router.

Step 309: and calling the ndc command to set the local DNS, the subnet mask and the routing information.

Step 310: and normally accessing a target network to realize data downloading or uploading.

Here, the destination network is accessed normally, that is, the connection between the terminal device and the network side is established, and then the image file of the damaged partition can be downloaded from the network side, and the key data can be uploaded to the network side.

By adopting the technical scheme, when the android system is not normally started, a Linux binary program is called to start the WLAN minimum subsystem, connection is established with a network side, and data downloading or uploading is carried out, so that the method is very helpful for system recovery and key data backup.
