Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
First, an application scenario of the present disclosure will be explained. An APN is a parameter that must be configured when a terminal device accesses a network, and is used in a GPRS (General Packet Radio Service) backbone network to identify an external PDN (Packet data network, often referred to as the Internet) to be used. The APN includes an APN network identifier, which is an identifier that a user can connect to an external network through a GGSN/PGW (Gateway GPRS Support Node, GPRS Gateway Support Node/PDN Gateway, packet data network Gateway), and the identifier is allocated to an ISP (Internet Service Provider) or a company by a network operator, is consistent with a fixed Internet domain name, and is a mandatory component of the APN.
In addition, the APN determines which access method the terminal device accesses the network. At present, a configuration file is built in a terminal device, the configuration file configures APN information of each operator of each country, the terminal device matches the APN information in the configuration file according to the searched operator information, and configures APN parameters according to the matched APN information, thereby realizing network communication of the terminal device.
If the operator needs to change the APN configuration information during system upgrade, the terminal device also needs to synchronously perform system upgrade, and updates the APN parameter of the terminal device according to the APN configuration information after the operator upgrade, otherwise, the terminal device may not be able to access the operator network. However, an abnormal situation may occur when the operator upgrades the system, which causes that the terminal device cannot establish a data connection with the network device of the operator according to the updated APN parameter, so that the data service of the terminal device is unavailable, and user experience is affected.
In order to solve the above problems, the present disclosure provides a method, an apparatus, a storage medium, and a terminal device for establishing a data connection, where after the terminal device establishes a data connection abnormality with a network device according to a current APN parameter, a target APN parameter may be acquired again, and a data connection is established with the network device again through the target APN parameter, so that a problem that a data service of the terminal device is unavailable may be solved in a manner of modifying an APN parameter of the terminal device, and thus, user experience may be improved.
The present disclosure is described below with reference to specific examples.
Fig. 1 is a flowchart illustrating a method for establishing a data connection according to an exemplary embodiment, where the method is applied to a terminal device, as shown in fig. 1, and includes:
s101, acquiring a current APN parameter corresponding to the terminal equipment.
The current APN parameter may be an APN parameter configured in an operating system currently used by the terminal device, where the APN parameter is provided by an operator, and includes configuration information of an internal Network of the operator, and the APN parameter may include Carrier (name), MCC (Mobile Country Code), MNC (Mobile Network Code, Mobile Network number), APN, Proxy (address of a Proxy server), Port (Port number of the Proxy server), Mmsc (Multimedia Messaging Service Center), mmspy (address of a Multimedia message Proxy server), mmspy (Port number of the Multimedia message Proxy server), Protocol (APN Protocol), User (User), Password (Password), authentication type, and the like.
In this step, after the user opens the mobile network mode in the terminal device, or when the application installed in the terminal device needs to use the data service, the terminal device may obtain, according to a currently used SIM (Subscriber Identity Module) card, an MCC value and an MNC value corresponding to the terminal device, and obtain, according to the MCC value and the MNC value, a current APN parameter corresponding to the MCC value and the MNC value from an APN database preconfigured in the terminal device.
The APN database may include APN parameters corresponding to all operators around the world. Because there are many global operators, APN parameters of some operators may be lacking in an APN database configured in advance in the terminal device, or APN parameters may be updated by some operators when a system is upgraded, in this case, the terminal device needs to update the APN parameters in the terminal device according to the APN parameters of the lacking operators or updated APN parameters updated by the system of the operators, so that the APN parameters in the terminal device and the APN parameters of the operators keep synchronous. After the operating system of the terminal device is upgraded, the current APN parameter corresponding to the terminal device is the new APN parameter after the operating system of the terminal device is upgraded.
And S102, establishing data connection with the network equipment according to the current APN parameter.
In this step, after obtaining the current APN parameter, the terminal device may send a connection request instruction to the network device according to the current APN parameter, and the network device may return a connection result to the terminal device according to the connection request instruction, where if the connection result is successful, it indicates that the data connection between the terminal device and the network device is successful, and if the connection result is failure, it indicates that the data connection between the terminal device and the network device is failed.
Further, after the data connection between the terminal device and the network device is successfully established, it needs to be further determined whether the data path of the terminal device is capable of transmitting data, that is, whether the communication between the terminal device and the network device is normal, for example, the terminal device may ping a preset website, if the terminal device is capable of receiving a data packet returned by the ping, it indicates that the data path of the terminal device is capable of transmitting data, and if the terminal device is not capable of receiving the data packet returned by the ping, it indicates that the data path of the terminal device is incapable of transmitting data.
S103, under the condition that the data connection established according to the current APN parameter is abnormal, acquiring a target APN parameter.
The data connection abnormality may include that the data connection is failed to be established, or after the data connection is successfully established, the data path of the terminal device cannot transmit data.
In this step, when it is determined that the terminal device fails to establish the data connection according to the current APN parameter or a data path of the terminal device cannot transmit data, a target APN parameter pre-stored in the terminal device may be obtained, where the target APN parameter may be an APN parameter used when the terminal device establishes a normal data connection with the network device at any time. For example, when the terminal device establishes a data connection with the network device, if the data connection between the terminal device and the network device is normal, the APN parameter used for establishing the data connection may be stored in the terminal device as the target APN parameter. And under the condition that the data connection established by the terminal equipment according to the current APN parameter is abnormal, the stored target APN parameter can be acquired.
And S104, establishing data connection with the network equipment again according to the target APN parameter.
In this step, after the target APN parameter is obtained, referring to the manner of establishing the data connection with the network device according to the current APN parameter in step S102, the data connection with the network device may be re-established according to the target APN parameter, which is not described herein again.
By adopting the method, after the terminal equipment establishes data connection abnormity with the network equipment according to the current APN parameter, the target APN parameter can be obtained, and the data connection is reestablished with the network equipment through the target APN parameter, so that the data connection can be reestablished according to the target APN parameter under the condition that the data connection abnormity is established with the terminal equipment due to the error of the current APN parameter, the problem that the data service of the terminal equipment is unavailable is solved, and the user experience is improved.
Fig. 2 is a flowchart illustrating a second method of establishing a data connection according to an example embodiment, as shown in fig. 2, the method including:
s201, obtaining the current APN parameter corresponding to the terminal equipment.
The current APN parameter may be an APN parameter configured in an operating system currently used by the terminal device, where the APN parameter may include Carrier, MCC, MNC, APN, Proxy, Port, Mmsc, mmproxy, mmmsp, Protocol, User, Password, Authtype, and the like, and the APN parameter is merely an example, and is not limited in this disclosure.
It should be noted that the current APN parameter may be an APN parameter used by the terminal device to establish a data connection for the first time after the operating system is upgraded.
S202, establishing data connection with the network equipment according to the current APN parameter.
S203, if the data connection established according to the current APN parameter is abnormal, execute step S204 and step S206, or execute step S205 to step S205, and if the data connection established according to the current APN parameter is normal, execute step S207.
The data connection abnormality may include that the data connection is failed to be established, or after the data connection is successfully established, the data path of the terminal device cannot transmit data.
In this step, after the terminal device sends a connection instruction to the network device according to the current APN parameter, a connection result returned by the network device may be monitored by a data link management unit in the terminal device. If the connection result is connection success, it indicates that the data connection between the terminal device and the network device is established successfully, and if the connection result is connection failure, it indicates that the data connection between the terminal device and the network device is established failure.
It should be noted that, under the condition that the data connection of the terminal device is successfully established, due to the problems of an APN parameter error, an operator network abnormality, and the like, the data service of the terminal device may be unavailable, and the user may still be unable to surf the internet normally. Therefore, after the data connection between the terminal device and the network device is successfully established, it needs to be further determined whether the data path of the terminal device is capable of transmitting data, that is, whether the communication between the terminal device and the network device is normal.
S204, obtaining the effective APN parameter pre-stored in the target storage area of the terminal equipment, and taking the effective APN parameter as the target APN parameter.
The target storage area may be a storage area that is not updated when the terminal device upgrades the system, and the valid APN parameter may include an APN parameter used by the terminal device to establish a normal data connection with the network device for the last time.
In this step, the terminal device may obtain the valid APN parameter according to a preset path under the condition that the data connection established according to the current APN parameter is abnormal, because the terminal device may establish the data connection with the network device according to the valid APN parameter before the data connection is established this time, in consideration of a general condition, operations such as network upgrade of an operator may be compatible forward, that is, the updated APN parameter may also be compatible with an old APN parameter before the upgrade, therefore, under the condition that the terminal device establishes the data connection according to the current APN parameter is abnormal, the valid APN parameter may be obtained, and the data connection is attempted to be reestablished according to the valid APN parameter.
S205, obtaining a pre-stored historical APN parameter, and updating the current APN parameter according to the historical APN parameter to obtain the target APN parameter.
The historical APN parameters may include all APN parameters used by the operator and all APN parameters set by the terminal device. In the using process of the terminal, the historical APN parameter may be updated in real time, for example, after the terminal device updates and updates the current APN parameter through an operating system, the current APN parameter may be added to the historical APN parameter.
In this step, after obtaining the historical APN parameter, the current APN parameter may be adjusted according to the historical APN parameter by the parameter adjusting unit of the terminal device, so as to obtain the target APN parameter. Because the APN parameter includes multiple parameters, in a possible implementation manner, a first parameter to be adjusted may be determined from the current APN parameter according to a preset parameter adjustment sequence, a first target history parameter corresponding to the first parameter to be adjusted may be determined from the history APN parameter, and the first parameter to be adjusted may be updated through the first target history parameter to obtain the target APN parameter.
The preset parameter adjustment sequence may be determined according to the number of times of errors occurring in each parameter within a preset time period, and the APN parameters are arranged according to the sequence of the number of times of errors from high to low, where the preset time period may be 1 month or 1 year, and this disclosure does not limit this. For example, if the APN parameter with the largest number of errors is Protocol, the Protocol may be arranged at the first position of the preset parameter adjustment sequence, and if the APN parameter with the smallest number of errors is Proxy, the Proxy may be arranged at the last position of the preset parameter adjustment sequence. The above-mentioned manner for determining the preset parameter adjustment sequence is only an example, and the preset parameter adjustment sequence may also be determined in other manners, which is not limited in this disclosure.
For example, after the terminal device obtains the historical APN parameter, the preset parameter adjustment order may be obtained, the parameter to be adjusted arranged at the first position in the preset parameter adjustment order is determined from the current APN parameter as the first parameter to be adjusted, and then, the first target historical parameter corresponding to the first parameter to be adjusted may be determined from the historical APN parameter, and the first parameter to be adjusted is updated to the first target historical parameter. For example, if the Protocol arranged in the first position in the preset parameter adjustment sequence is a Protocol, the terminal device may first determine that the Protocol is a first parameter to be adjusted from the current APN parameter, use the Protocol in the historical APN parameter as a first target historical parameter, and then replace the Protocol in the current APN parameter with the Protocol in the historical APN parameter to obtain the target APN parameter.
In addition, the first parameter to be adjusted may also be adjusted according to a preset value of the first parameter to be adjusted, for example, the preset value of the Protocol in the APN parameter may be IPV4, IPV6, or IPV4V6, and in the case that the value of the Protocol in the current APN parameter is IPV4, the value of the Protocol may be modified to be IPV6 or IPV4V 6.
S206, establishing data connection with the network equipment again according to the target APN parameter.
In this step, after determining the target APN parameter, the data connection between the terminal device and the network device may be reestablished according to the target APN parameter by using the data connection management unit of the terminal device.
It should be noted that, because the APN parameters include a plurality of APN parameters, after the terminal device fails to establish a data connection with the network device according to the current APN parameter, an error parameter in the current APN parameter cannot be determined, so that after the first parameter to be adjusted is updated through the first target history parameter to obtain the target APN parameter, the data connection with the network device again according to the target APN parameter may also be abnormal.
In a possible implementation manner, in the case that the data connection re-established with the network device according to the target APN parameter is abnormal, the connection establishing step may be executed in a loop until the data connection established according to the target APN parameter is normal. Wherein the connection establishing step comprises:
determining a second parameter to be adjusted from the current APN parameter according to the preset parameter adjustment sequence, wherein the second parameter to be adjusted is a next parameter to be adjusted of the first parameter to be adjusted, determining a second target historical parameter corresponding to the second parameter to be adjusted from the historical APN parameter, updating the second parameter to be adjusted through the second target historical parameter to obtain a new target APN parameter, establishing data connection with the network equipment according to the new target APN parameter, and taking the updated second parameter to be adjusted as the new first parameter to be adjusted under the condition that the data connection established according to the new target APN parameter is abnormal.
For example, when the first parameter to be adjusted is updated by the first target history parameter to obtain the target APN parameter, and the data connection established between the current APN parameter and the network device is abnormal again according to the target APN parameter, the parameter to be adjusted arranged at the second position in the preset parameter adjustment sequence may be determined from the current APN parameter as the second parameter to be adjusted, and then the second target history parameter corresponding to the second parameter to be adjusted may be determined from the history APN parameter, and the second parameter to be adjusted is updated to the second target history parameter. For example, if the next highest ranked Proxy in the preset parameter adjustment sequence is a Proxy, the terminal device may first determine the Proxy as a second parameter to be adjusted from the current APN parameter, use the Proxy in the historical APN parameter as a second target historical parameter, then replace the Proxy in the current APN parameter with the Proxy in the historical APN parameter to obtain the target APN parameter, and finally, the terminal device may reestablish a data connection with the network device according to the target APN parameter. If the data connection reestablished by the terminal equipment at this time is still abnormal, the new target APN parameter can be continuously obtained according to the mode, and the data connection is reestablished with the network equipment according to the new target APN parameter.
S207, taking the current APN parameter as a new effective APN parameter.
In this step, under the condition that the terminal device establishes normal data connection with the network device according to the current APN parameter, the valid APN parameter can be obtained, the current APN parameter and the valid APN parameter are compared, and under the condition that the current APN parameter is different from the valid APN parameter, the current APN parameter is taken as a new valid APN parameter and stored in the terminal device.
By adopting the method, after the terminal equipment establishes data connection abnormity with the network equipment according to the current APN parameter, the effective APN parameter or the historical APN parameter can be obtained, and the data connection is established again with the network equipment according to the effective APN parameter or the historical APN parameter, so that the effective APN parameter or the historical APN parameter is the APN parameter used by the terminal equipment for establishing normal data connection with the network equipment, and the data connection can be established with the network equipment according to the effective APN parameter, thereby solving the problem that the data service of the terminal equipment is unavailable, and improving the user experience.
The embodiment shown in fig. 2 is that the terminal device reestablishes data connection with the network device according to the valid APN parameter or the historical APN parameter when the data connection between the terminal device and the network device is abnormal according to the current APN parameter, and in another possible implementation manner, the terminal device may reestablish data connection with the network device according to the valid APN parameter first when the data connection between the terminal device and the network device is abnormal according to the current APN parameter, and reestablish data connection with the network device according to the historical APN parameter when the data connection between the terminal device and the network device is abnormal according to the valid APN parameter. Fig. 3 is a flowchart illustrating a third method of establishing a data connection according to an example embodiment, as shown in fig. 3, the method including:
s301, acquiring the current APN parameter corresponding to the terminal equipment.
The current APN parameter may be an APN parameter configured in an operating system currently used by the terminal device, where the APN parameter may include Carrier, MCC, MNC, APN, Proxy, Port, Mmsc, mmproxy, mmmsp, Protocol, User, Password, Authtype, and the like, and the APN parameter is merely an example, and is not limited in this disclosure.
It should be noted that the current APN parameter may be an APN parameter used by the terminal device to establish a data connection for the first time after the operating system is upgraded.
S302, establishing data connection with the network equipment according to the current APN parameter.
And S303, executing the step S304 to the step S309 when the data connection established according to the current APN parameter is abnormal, and executing the step S310 when the data connection established according to the current APN parameter is normal.
S304, obtaining the effective APN parameter pre-stored in the target storage area of the terminal equipment, and taking the effective APN parameter as the target APN parameter.
The target storage area may be a storage area that is not updated when the terminal device upgrades the system, and the valid APN parameter may include an APN parameter used by the terminal device to establish a normal data connection with the network device for the last time.
S305, establishing data connection with the network equipment again according to the target APN parameter.
S306, under the condition that the data connection between the target APN parameter and the network equipment is abnormal again according to the target APN parameter, the target APN parameter is used as a new current APN parameter, and a pre-stored historical APN parameter is obtained.
S307, updating the new current APN parameter according to the historical APN parameter to obtain a new target APN parameter.
