Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that the terms "first" and "second" and the like in the description and the claims of the present application are used for distinguishing between different objects and not for describing a particular sequential order. The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.

The following describes an application scenario according to the present application. In the process of updating the APN, the terminal equipment needs to acquire APN information to be determined in an APN configuration file from a server; then obtaining the current APN information of the current configuration of the terminal equipment, which is included in the APN database in the terminal equipment; then comparing the APN information to be determined with the current APN information; if the APN information to be determined is different from the current APN information, the APN information to be determined is updated to the APN database. It follows that in the prior art an update of an APN can be performed between a server and an APN database. However, if the APN database is abnormal (for example, when the user returns to factory setting of the terminal device, all data in the APN database is deleted, or when the user modifies data in the APN database, part of data in the APN database is in a lost state), the terminal device cannot perform normal communication. At this time, the user needs to perform wireless communication connection to the terminal device, and in the case of wireless communication connection, perform APN configuration to the terminal device. The wireless communication connection may be a wireless fidelity connection (wireless fidelity, wiFi), a bluetooth connection, a hotspot connection, or the like. It can be seen that when the APN database in the terminal device is abnormal, the APN configuration process is complicated.

It may be appreciated that the information types of the APN information to be determined and the current APN information are the same, and/or the APN information to be determined and the current APN information may include at least one information, respectively. For example, the information types of both the APN information to be determined and the current APN information are operator names.

It should be noted that, the terminal device according to the embodiments of the present application may include a mobile phone, a wearable device (for example, but not limited to, a watch (such as a watch, a wrist, etc.) supported by a wrist, a footlet (such as a shoe, a sock, or other products worn on a leg), a Glass (such as glasses, a helmet, a headband, etc.) supported by a head, and various non-mainstream product forms such as a smart garment, a schoolbag, a crutch, an accessory, etc.), a personal digital assistant (personal digital assistant, a PDA), a portable multimedia player (personal media player, a PMP) device, a notebook (note pad), a wireless broadband (wireless broadband, wibro) terminal, a tablet (personal computer, PC), a smart PC, a point of sale (POS), a vehicle-mounted computer, etc., which is not particularly limited.

In order to solve the above-mentioned problem, the present application may store an APN configuration file (i.e., corresponding to the first APN configuration file in the present application) used when the terminal device configures the APN last time before the communication connection is abnormal in the first non-erasable storage space. In this way, when the terminal equipment is in abnormal communication connection, the version numbers of the first APN configuration file and the second APN configuration file stored by the terminal equipment when leaving the factory can be compared, so that the terminal equipment is reset according to the comparison result of the version numbers. Therefore, under the condition that the version number of the first APN is larger than the version number of the second APN, the APN is reset to the terminal equipment according to the first APN configuration file, and the complicated process of carrying out APN updating according to the first APN configuration file after carrying out APN resetting according to the second APN configuration file in the prior art is avoided.

The present application will be described in detail with reference to specific examples.

Fig. 1 is a schematic diagram of an APN resetting method according to an embodiment of the present application, where the method may be applied to a terminal device, as shown in fig. 1, and the method may include:

101. under the condition that the terminal equipment is in abnormal communication connection, acquiring a first APN version number corresponding to a first APN configuration file and a second APN version number corresponding to a second APN configuration file; the first APN configuration file is an APN configuration file used when the terminal equipment is in the last time of configuring an APN before communication connection abnormality, the first APN configuration file is stored in a first non-erasable storage space, and the second APN configuration file is an APN configuration file pre-stored when the terminal equipment leaves a factory.

Wherein the first APN profile and the second APN profile may be extensible markup language (extensible markup language, xml) files. It should be appreciated that the extensible markup language is a subset of the standard generic markup language.

In an alternative embodiment of the present application, determining that the terminal device is in abnormal communication connection may include: and under the condition that the terminal equipment meets the first condition, determining that the terminal equipment is in the abnormal communication connection.

Wherein the first condition may include at least one of:

(1) Detecting a factory setting restoring instruction carried out on the terminal equipment;

(2) Detecting a change instruction of second APN information in a third APN configuration file included in the currently configured APN;

(3) No response message to the communication request message is detected within a preset time period, and the starting time of the preset time period may be the time of transmitting the communication request message; the method comprises the steps of,

(4) A communication failure message is detected.

It will be appreciated that for (1), in the case where the terminal device performs the factory reset, the terminal device clears the information stored in the storage space other than the non-erasable storage space. In the related art, since the APN configuration information is stored in the other storage space, after the terminal device performs the factory reset, the terminal device does not store the second APN configuration file any more, and thus the APN reset cannot be performed based on the second APN configuration file. In the application, the second APN configuration file is stored in the first non-erasable storage space, so that the terminal equipment cannot clear the second APN configuration file under the condition of detecting the command of restoring the factory setting, and therefore, the terminal equipment can reset the APN according to the second APN configuration file.

For (2), considering that when the user changes the APN of the terminal equipment, the probability of changing errors is higher, so that the APN part function cannot be used, and normal communication connection cannot be performed. Therefore, the application can reset the APN of the terminal equipment when detecting the change instruction of the currently configured APN. It is to be appreciated that the second APN information can include APN parameters such as an access point name (e.g., cmwap, etc.), an agent, an access point name type (e.g., default, etc.), and so forth.

Regarding (3) and (4), in consideration of the fact that the terminal device performs a communication operation when the communication connection is normal, the communication operation may include, for example, an information access operation (e.g., an operation of browsing a web page, an information upload operation, an information download operation, etc.), an information transmission operation (e.g., a transmission operation of a short message, a multimedia message, etc.), or a call operation (e.g., a voice call operation, etc.), etc. Thus, if the terminal device cannot perform the communication operation, it can be determined that the terminal device is in abnormal communication connection. For example, if the communication operation includes an information sending operation or a call operation, the terminal device generates a communication failure message and displays the communication failure message to the user in a case that the communication operation cannot be performed; if the communication operation includes an information access operation, the terminal device does not detect a response message regarding the communication request message within a preset period of time in a case where the information access operation cannot be performed. The first condition described above is merely an exemplary one, and the present application is not particularly limited thereto.

In an alternative embodiment of the present application, the terminal device may obtain first storage path information of the first non-erasable storage space, and second storage path information of a second non-erasable storage space, where the second non-erasable storage space is used to store the second APN configuration file. Thus, the obtaining the first APN version number corresponding to the first APN configuration file and the second APN version number corresponding to the second APN configuration file in this step may include: acquiring a first APN version number corresponding to the first APN configuration file according to the first storage path information; and acquiring a second APN version number corresponding to the second APN configuration file according to the second storage path information.

Wherein the first APN version number and the second APN version number may be pre-stored by, but not limited to:

In an embodiment, when a first version number field is set in a first APN configuration file, the obtaining, according to the first storage path information, a first APN version number corresponding to the first APN configuration file may include: and acquiring a first APN configuration file according to the first storage path information, and reading a first APN version number from a first version number field of the first APN configuration file.

In another embodiment, when the first version number field is set in the first APN configuration file, the obtaining, according to the first storage path information, the first APN version number corresponding to the first APN configuration file may include: and under the condition that the first file corresponding to the specified file identifier exists in the first non-erasable storage space according to the first storage path information, determining the first file corresponding to the specified file identifier as the first APN configuration file, and acquiring a first APN version number indicated by a first version number field in the first APN configuration file.

It should be understood that, because the APN configuration file is generally provided with a corresponding designated file identifier, the present application can determine whether the first file of the designated file identifier exists in the first non-erasable storage space indicated by the first storage path information through the designated file identifier, if not, it is determined that the first APN configuration file is not stored in the terminal device, and at this time, the step of comparing the first APN version number with the second APN version number is not required, and the APN is directly reset to the terminal device according to the second APN configuration file.

Likewise, in an embodiment, when the second version number field is set in the second APN configuration file, the obtaining, according to the second storage path information, the first APN version number corresponding to the second APN configuration file may include: and acquiring a second APN configuration file according to the second storage path information, and reading a second APN version number from a second version number field of the second APN configuration file.

In another embodiment, when the second version number field is set in the second APN configuration file, the obtaining, according to the second storage path information, the second APN version number corresponding to the second APN configuration file may include: and under the condition that the third file corresponding to the specified file identifier exists in the second non-erasable storage space according to the second storage path information, determining the third file corresponding to the specified file identifier as the second APN configuration file, and acquiring a second APN version number indicated by a second version number field in the second APN configuration file.

It should be noted that, the first version number field and the second version number field may be the same field or may be different fields. For example, the first version number field may be a fifth field in the first APN profile, and the second version number field may be an eighth field in the second APN profile, which are merely exemplary, and the present application is not limited thereto.

Mode two, the first APN configuration file has a corresponding first version number file, the second APN configuration file has a corresponding second version number file, the first version number file is used for storing a first APN version number corresponding to the first APN configuration file, and the second version number file is used for storing a second APN version number corresponding to the second APN configuration file.

In an embodiment, when the first APN configuration file has the corresponding first version number file, the obtaining, according to the first storage path information, the first APN version number corresponding to the first APN configuration file may include: acquiring a first APN configuration file according to the first storage path information, acquiring a first version number file corresponding to the first APN configuration file, and reading a first APN version number from the first version number file. Or, the mapping relation between the first storage path information and the first APN version number is stored in the first version number file, so that the terminal device can obtain the first APN version number corresponding to the first storage path information from the first version number file.

In another embodiment, when the first APN configuration file has the corresponding first version number file, the obtaining, according to the first storage path information, the first APN version number corresponding to the first APN configuration file may include: and under the condition that the second file corresponding to the specified file identifier exists in the first non-erasable storage space according to the first storage path information, determining the second file corresponding to the specified file identifier as the first APN configuration file, acquiring a first version number file corresponding to the first APN configuration file, and acquiring a first APN version number from the first version number file.

Or, the second version number file stores a mapping relationship between the second storage path information and the second APN version number, so the terminal device may obtain the second APN version number corresponding to the second storage path information from the second version number file.

In another embodiment, when the second APN configuration file has the corresponding second version number file, the obtaining, according to the second storage path information, the second APN version number corresponding to the second APN configuration file may include: and under the condition that the fourth file corresponding to the specified file identifier exists in the second non-erasable storage space according to the second storage path information, determining the fourth file corresponding to the specified file identifier as the second APN configuration file, acquiring a second version number file corresponding to the second APN configuration file, and acquiring a second APN version number from the second version number file.

It should be noted that the first version number file and the second version number file may be the same file, and the version number mapping relationship is stored in the same file. The version number mapping relation comprises a mapping relation between an APN version number and storage path information. Exemplary version number mappings include: a mapping relationship between the first APN version number and the first storage path information, and a mapping relationship between the second APN version number and the second storage path information. The above examples are illustrative only, and the application is not limited thereto.

102. And under the condition that the version number of the first APN is larger than the version number of the second APN, resetting the APN of the terminal equipment according to the first APN configuration file.

In the embodiment of the application, under the condition that the version number of the first APN is larger than the version number of the second APN, first APN information is acquired from the first APN configuration file; and importing the first APN information into an APN database to reset the APN.

Alternatively, the terminal device may delete the APN database in case it is determined that the terminal device is in a communication connection abnormality. In this way, this step may reconstruct the APN database so as to import the first APN information into the reconstructed APN database for APN reset.

In an alternative embodiment, in the case where the first APN version number is smaller than the second APN version number, the reset of the APN may be performed by, but is not limited to, the following:

in the first mode, the terminal device may reset the APN of the terminal device according to the second APN configuration file.

Mode two, terminal equipment demonstrates the APN and selects the interface, APN selects the interface to include: first information corresponding to a first APN (namely an APN corresponding to a first APN configuration file) and a selection control corresponding to the first APN; second information corresponding to a second APN (namely an APN corresponding to a second APN configuration file), and a selection control corresponding to the second APN. Wherein the first information may include, but is not limited to, at least one of: the method comprises the steps of identifying a first APN, a first APN version number and first APN key information in a first APN configuration file; the second information may include, but is not limited to, at least one of: the identification of the second APN, the second APN version number and second APN key information in the second APN configuration file. The terminal equipment receives the selection operation of the user on the selection control corresponding to the target APN, and responds to the selection operation, and the terminal equipment is reset according to the APN configuration file corresponding to the target APN. The target APN includes a first APN or a second APN. For example, as shown in fig. 2, the APN selection interface may include an identification of a first APN, a first port, a first proxy, a first access point name type, and the like, and the second information may include an identification of a second APN, a second port, a second proxy, a second access point name type, and the like. The above examples are illustrative only, and the application is not limited thereto.

Since the user cannot perceive whether the terminal device is reset with the first APN profile or with the second APN profile. Therefore, in an alternative embodiment of the present application, if the terminal device completes the APN reset through the first APN configuration file, the terminal device may display the first APN identifier corresponding to the first APN configuration file. Thus, the user can know the APN condition of the terminal equipment in time.

In an alternative embodiment of the present application, in order to improve autonomous selectivity of a user, when a version number of a first APN is greater than a version number of a second APN, a prompting message is output, where the prompting message is used to prompt the user whether to reset an APN by using first APN configuration information corresponding to the version number of the first APN. And executing the step of resetting the APN to the terminal equipment according to the first APN configuration file under the condition that the user is detected to determine to use the first APN configuration information to reset the APN. And executing the step of resetting the APN according to the second APN configuration file when the user is detected to confirm that the APN is not reset by using the first APN configuration information. The output hint message is shown in fig. 3, for example.

By adopting the method, the APN configuration file (namely, the APN configuration file is equivalent to the first APN configuration file in the application) used when the terminal equipment is configured with the APN last time before communication connection abnormality can be stored in the first non-erasable storage space. In this way, when the terminal equipment is in abnormal communication connection, the version numbers of the first APN configuration file and the second APN configuration file stored by the terminal equipment when leaving the factory can be compared, so that the terminal equipment is reset according to the comparison result of the version numbers. Therefore, under the condition that the version number of the first APN is larger than the version number of the second APN, the APN is reset to the terminal equipment according to the first APN configuration file, and the complicated process of carrying out APN updating according to the first APN configuration file after carrying out APN resetting according to the second APN configuration file in the prior art is avoided.

Referring to fig. 1, as shown in fig. 4, the method may further include:

103. and under the condition that an APN updating instruction is detected, acquiring the first APN configuration file from a server.

In an alternative embodiment of the present application, the terminal device may generate an APN update instruction in response to an APN update operation input by a user. Illustratively, the APN update operation may include at least one of a touch update operation, a voice update operation, a gesture update operation, and the like. The APN update operation may be an operation of updating first APN information (for example, information of an APN identifier, an agent, a port, etc.) included in the first APN configuration file.

In another optional embodiment of the present application, the server stores in advance a third APN version number corresponding to an APN currently configured by the terminal device, and when detecting the first APN configuration file, determines whether the first APN version number corresponding to the first APN configuration file is greater than the third APN version number, and if so, sends an APN update message to the terminal device; if the APN is smaller than the APN, the terminal equipment does not need to be updated. In this way, the terminal device generates an APN update instruction in the case of detecting a confirmation update operation with respect to an APN update message.

Further, the different APNs have corresponding user whitelists and/or user blacklists, for example, the user blacklists and the user blacklists comprise mobile phone numbers. The user blacklist cannot access the corresponding APN, and the user whitelist can access the corresponding APN. In this way, when the server detects the first APN configuration file, the server may acquire the mobile phone number of the terminal device, determine whether the mobile phone number is in a blacklist corresponding to the first APN (i.e., the APN corresponding to the first APN configuration file), and if not, execute the step of determining whether the version number of the first APN corresponding to the first APN configuration file is greater than the version number of the third APN; if yes, the terminal equipment does not need to update the APN.

104. And if the version number of the first APN corresponding to the first APN configuration file is larger than the version number of the third APN corresponding to the APN currently configured by the terminal equipment, storing the first APN configuration file into the first non-erasable storage space.

In an alternative embodiment, the terminal device may remove the APN configuration file corresponding to the third APN configuration file currently configured from the first non-erasable storage space, and store the first APN configuration file in the first non-erasable storage space, so as to update the APN of the terminal device according to the first APN configuration file in the first non-erasable storage space. Optionally, the terminal device may parse the first APN configuration file to obtain first APN information; and replacing partial information in the APN database corresponding to the first APN information, or deleting the APN database by the terminal equipment, and reconstructing the APN database so as to import the first APN information into the reconstructed APN database to reset the APN.

For ease of understanding, this embodiment is described by taking an example in which an APN profile obtained from a server includes a first APN profile. Step 103 may be performed before step 101.

Of course, step 103 may be replaced by: and under the condition that the APN updating instruction is detected, acquiring a fourth APN configuration file from the server. In this way, if this step is performed before step 101, the APN in the terminal device is updated multiple times, so that the first APN configuration file is used when the APN is configured last time before the terminal device is in abnormal communication connection. If the step is executed after step 102, if the fourth APN version number corresponding to the fourth APN configuration file is greater than the third APN version number corresponding to the APN currently configured by the terminal device, the third APN configuration file corresponding to the APN currently configured is removed from the first non-erasable storage space, and the fourth APN configuration file is stored in the first non-erasable storage space, so that the terminal device is updated according to the fourth APN configuration file in the first non-erasable storage space.

By adopting the method, the application can store the latest version of APN configuration file (namely the second APN configuration file equivalent to the application) into the first non-erasable storage space in the APN updating process of the terminal equipment. In this way, when the terminal equipment is in abnormal communication connection, the version numbers of the first APN configuration file and the second APN configuration file stored by the terminal equipment when leaving the factory can be compared, so that the terminal equipment is reset according to the comparison result of the version numbers. Therefore, under the condition that the version number of the first APN is larger than the version number of the second APN, the APN is reset to the terminal equipment according to the first APN configuration file, and the complicated process of carrying out APN updating according to the first APN configuration file after carrying out APN resetting according to the second APN configuration file in the prior art is avoided.
