Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
First, an application scenario of the present disclosure will be described. An APN is a parameter that must be configured when a terminal device accesses the network, and is used in the GPRS (General Packet Radio Service ) backbone to identify an external PDN (Packet data network, packet data network, so-called Internet) to be used. The APN includes an APN network identity, which is an identity that a user can connect to an external network through a GGSN/PGW (Gateway GPRS Support Node, GPRS Gateway support node/PDN Gateway), which is assigned by the network operator to an ISP (Internet Service Provider ) or company, in correspondence with its fixed Internet domain name, is an optional component of the APN.
In addition, the APN determines which access mode the terminal device accesses the network. Currently, a configuration file is built in the terminal equipment, the configuration file configures APN information of each operator of each country, the terminal equipment matches APN information in the configuration file according to the searched operator information, and APN parameters are configured according to the matched APN information, so that network communication of the terminal equipment is realized.
If the operator needs to change the APN configuration information during system upgrading, the terminal equipment also needs to synchronously upgrade the system, and update the APN parameter of the terminal equipment according to the APN configuration information after the upgrade of the operator, otherwise, the terminal equipment may not be able to access the operator network. However, when the operator upgrades the system, an abnormal situation may occur, so that the terminal device cannot establish 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 the 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 with a network device according to a current APN parameter, the terminal device may reacquire a target APN parameter, and establish a data connection with the network device again through the target APN parameter, so that the problem that a data service of the terminal device is unavailable can be solved by modifying the APN parameter of the terminal device, thereby improving user experience.
The present disclosure is described below in connection with specific embodiments.
Fig. 1 is a flowchart illustrating a method for establishing a data connection according to an exemplary embodiment, and as shown in fig. 1, the method is applied to a terminal device, 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 Proxy), port (Port number of Proxy), msc (Multimedia Messaging Service Center, multimedia information service center), msproxy (address of multimedia message Proxy), msport (Port number of multimedia message Proxy), protocol (APN Protocol), user, password, authtype (identity authentication type), etc., which are just illustrative, and the present disclosure is not limited thereto.
In this step, after the user opens the mobile network mode in the terminal device, or when an application installed in the terminal device needs to use a 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 by the terminal device.
The APN database may include APN parameters corresponding to all operators worldwide. Because of the large number of global operators, an APN parameter of a part of operators may be absent in an APN database preconfigured in the terminal device, or an APN parameter may be updated by a part of operators during system upgrade, in this case, the terminal device needs to update the APN parameter in the terminal device according to the missing APN parameter of the operator or the APN parameter updated by the operator system upgrade, so that the APN parameter in the terminal device and the APN parameter of the operator remain synchronous. After the operating system of the terminal equipment is upgraded, the current APN parameter corresponding to the terminal equipment is the new APN parameter of the terminal equipment after the operating system is upgraded.
S102, establishing data connection with the network equipment according to the current APN parameter.
In this step, after the current APN parameter is obtained, 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, 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 failed, 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 established successfully, it needs to be further determined whether the data path of the terminal device can transmit 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 can receive the data packet returned by ping, it indicates that the data path of the terminal device can transmit data, and if the terminal device cannot receive the data packet returned by ping, it indicates that the data path of the terminal device cannot transmit data.
S103, under the condition that the data connection established according to the current APN parameter is abnormal, acquiring a target APN parameter.
The abnormal data connection may include a failure of establishing the data connection, or after the successful establishment of the data connection, the data path of the terminal device cannot transmit data.
In this step, when it is determined that the terminal device fails to establish a data connection according to the current APN parameter, or the data path of the terminal device cannot transmit data, a target APN parameter stored in the terminal device in advance 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 the current establishment of 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, acquiring the stored target APN parameter.
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, the data connection with the network device may be re-established according to the target APN parameter by referring to the manner of establishing the data connection with the network device according to the current APN parameter in step S102, which is not described herein.
By adopting the method, after the terminal equipment establishes data connection with the network equipment according to the current APN parameter, the target APN parameter can be acquired, and the data connection is established with the network equipment again through the target APN parameter, so that under the condition that the data connection is established with the terminal equipment due to the error of the current APN parameter, the data connection can be established again according to the target 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 flow chart illustrating a second method of establishing a data connection, as shown in fig. 2, according to an exemplary embodiment, the method comprising:
s201, 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, and the APN parameter may include Carrier, MCC, MNC, APN, proxy, port, mmsc, mmsproxy, mmsport, protocol, user, password, authtype, etc., which is only an example, and the disclosure is not limited thereto.
It should be noted that, the current APN parameter may be an APN parameter used by the terminal device for first establishing a data connection after upgrading the operating system.
S202, establishing data connection with the network equipment according to the current APN parameter.
Step 203, when the data connection established according to the current APN parameter is abnormal, step 204 and step 206 are executed, or step 205 to step 205 are executed, and when the data connection established according to the current APN parameter is normal, step 207 is executed.
The abnormal data connection may include a failure of establishing the data connection, or after the successful establishment of the data connection, 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, the connection result returned by the network device may be monitored by the data link management unit in the terminal device. And if the connection result is connection success, the data connection between the terminal equipment and the network equipment is successfully established, and if the connection result is connection failure, the data connection between the terminal equipment and the network equipment is failed.
It should be noted that, in the case that the data connection of the terminal device is successfully established, the data service of the terminal device may not be available due to the problems of an APN parameter error, an operator network abnormality, and the like, and the user may not be able to normally access the internet. Therefore, after the data connection between the terminal device and the network device is successfully established, it is further required to determine 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 an effective APN parameter pre-stored in a 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 the terminal device will not update when upgrading 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 last time.
In this step, under the condition that the data connection established according to the current APN parameter is abnormal, the terminal device may acquire the valid APN parameter according to a preset path, because the terminal device may establish data connection with the network device according to the valid APN parameter before the data connection is established, considering that operations such as network upgrade of an operator may be forward compatible under general circumstances, that is, the updated APN parameter may also be compatible with an old APN parameter before the upgrade, therefore, under the condition that the data connection is established according to the current APN parameter by the terminal device is abnormal, the valid APN parameter may be acquired, and an attempt is made to reestablish the data connection according to the valid APN parameter.
S205, acquiring 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 an operator and all APN parameters set by the terminal device. The historical APN parameter may be updated in real time during the use of the terminal, for example, after the terminal device updates the current APN parameter by an operating system upgrade, the current APN parameter may be added to the historical APN parameter.
In this step, after the historical APN parameter is obtained, the current APN parameter may be adjusted by the parameter adjustment unit of the terminal device according to the historical APN parameter to obtain the target APN parameter. Because the APN parameter includes a plurality of 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 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 may be updated through the first target historical parameter to obtain the target APN parameter.
The preset parameter adjustment sequence may be determined according to the number of errors occurring in each parameter in a preset time period, and the APN parameters are arranged according to the sequence of the number of errors from more to less, where the preset time period may be 1 month or 1 year, which is not limited in the disclosure. For example, if the number of errors in the APN parameter is the largest, the protocols may be arranged at the first bit of the preset parameter adjustment sequence, and if the number of errors in the APN parameter is the smallest, the protocols may be arranged at the last bit of the preset parameter adjustment sequence. The above manner of determining the preset parameter adjustment sequence is merely illustrative, and the preset parameter adjustment sequence may be determined by other manners, which is not limited in this disclosure.
For example, after the terminal device obtains the historical APN parameter, the preset parameter adjustment sequence may be obtained, a parameter to be adjusted arranged in a first position in the preset parameter adjustment sequence is determined from the current APN parameter and is used as the first parameter to be adjusted, and then a 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 first Protocol is arranged in the preset parameter adjustment sequence, the terminal device may determine that the Protocol is the first parameter to be adjusted from the current APN parameter, take the Protocol in the historical APN parameter as the 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 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 IPV4V6.
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 may be established with the network device again by the data connection management unit of the terminal device according to the target APN parameter.
It should be noted that, because the APN parameter includes 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 after the first parameter to be adjusted is updated through the first target history parameter, the data connection established with the network device according to the target APN parameter may be abnormal after the target APN parameter is obtained.
In one possible implementation, in the case of an abnormal data connection re-established with the network device according to the target APN parameter, the connection establishment step may be performed in a loop until the data connection established according to the target APN parameter is normal. The connection establishment step comprises the following steps:
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 the 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 with the network device is abnormal 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 to be used as the second parameter to be adjusted, and then, a 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 be the second target history parameter. For example, if the Proxy is arranged in the second order in the preset parameter adjustment sequence, the terminal device may determine that the Proxy is the second parameter to be adjusted from the current APN parameter, take the Proxy in the history APN parameter as the second target history parameter, then replace the Proxy in the current APN parameter with the Proxy in the history APN parameter to obtain the target APN parameter, and finally, the terminal device may reestablish the data connection with the network device according to the target APN parameter. If the data connection re-established by the terminal equipment is still abnormal, the new target APN parameter can be continuously acquired according to the mode, and the data connection is re-established 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, when the terminal device establishes a normal data connection with the network device according to the current APN parameter, the valid APN parameter may be obtained, the current APN parameter and the valid APN parameter are compared, and when the current APN parameter is different from the valid APN parameter, the current APN parameter is stored in the terminal device as a new valid APN parameter.
After the terminal equipment establishes data connection with the network equipment according to the current APN parameter, the method can acquire the effective APN parameter or the historical APN parameter, and establishes data connection with the network equipment again according to the effective APN parameter or the historical APN parameter.
In the embodiment shown in fig. 2, when the terminal device establishes a data connection with the network device according to the current APN parameter, the terminal device establishes a data connection with the network device again according to the valid APN parameter or the historical APN parameter. Fig. 3 is a flow chart illustrating a third method of establishing a data connection, as shown in fig. 3, according to an exemplary embodiment, the method comprising:
S301, 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, and the APN parameter may include Carrier, MCC, MNC, APN, proxy, port, mmsc, mmsproxy, mmsport, protocol, user, password, authtype, etc., which is only an example, and the disclosure is not limited thereto.
It should be noted that, the current APN parameter may be an APN parameter used by the terminal device for first establishing a data connection after upgrading the operating system.
S302, establishing data connection with the network equipment according to the current APN parameter.
Step 303, when the data connection established according to the current APN parameter is abnormal, steps S304 to S309 are executed, and when the data connection established according to the current APN parameter is normal, step S310 is executed.
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 the terminal device will not update when upgrading 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 last time.
S305, establishing data connection with the network equipment again according to the target APN parameter.
S306, under the condition of establishing data connection abnormality with the network equipment again according to the target APN parameter, taking the target APN parameter as a new current APN parameter, and acquiring a prestored historical APN parameter.
S307, updating the new current APN parameter according to the historical APN parameter to obtain a new target APN parameter.
S308, establishing data connection with the network equipment again according to the new target APN parameter.
S309, when the data connection is established with the network equipment according to the new target APN parameter, the new APN parameter is used as a new effective APN parameter.
S310, taking the current APN parameter as a new effective APN parameter.
It should be noted that, the specific implementation manner of step S301 to step S310 may refer to the specific implementation manner of the embodiment shown in fig. 1 and fig. 2, which is not described herein again.
