And adopting the standby network access parameters to carry out network access.

In the embodiment of the disclosure, when the number of continuous failures of the access parameter of the main network reaches the threshold, the access is performed by adopting the access parameter of the standby network, and the access success of the access by adopting the access parameter of the standby network can be ensured because the access parameter of the standby network is backed up when the access is successful last time. Therefore, the problem that the terminal cannot acquire the IP address and register to the network management system after the network access parameters are modified into the error parameters and becomes an out-of-management state can be avoided. Meanwhile, the scheme does not need to be manually participated, a large amount of human resources are saved, the efficiency is high, and customer complaints are avoided.

Optionally, the acquiring the standby network access parameter stored in the terminal includes:

and reading the standby network access parameters from a database based on the network access parameter switching request.

In the implementation mode, the data is read from the database in a data request mode, namely, the data in the database is read in a packaging interface mode, so that the smooth completion of the data reading is ensured.

Optionally, the generating the network access parameter switching request includes:

Acquiring a count value of a network access counting module in the terminal, wherein the count value is used for indicating the continuous failure times;

and when the count value reaches the threshold value, generating the network access parameter switching request through the network module.

In the implementation manner, the switching of the active and standby parameters is realized by acquiring the continuous failure times when the active access network parameters are adopted to access, so that an access parameter switching request can be generated when the continuous failure times reach a threshold value.

Optionally, the reading the standby network access parameter from the database based on the network access parameter switching request includes:

In the implementation manner, the parameter source identifier is adopted to mark the source of the network access parameter, so that the source of the currently used network access parameter can be determined according to the identifier, and the identifier can be modified when the network access parameter needs to be switched, so that the terminal can determine the source of the modified network access parameter based on the identifier.

Optionally, the method further comprises:

and recording the continuous failure times of network access by adopting the main network access parameters.

In this implementation, by recording the number of consecutive failures when the primary access network parameter is used for access, switching between the primary and secondary parameters can be performed when the number of consecutive failures reaches a threshold.

and counting the number of continuous failures through a network access counting module in the terminal, wherein the network access counting module accumulates the count value based on the network access state notification indicating the access failure generated by the network module.

In this implementation, the network access status notification is generated indicating access failures, i.e. the count of consecutive failures is incremented by one. For network access using a single transport protocol, the count of consecutive failures is incremented by one for each access failure. For the access mode of dual stack switching, when the number of dual stack switching cycles reaches the switching threshold, the count of continuous failures is increased by one, so that the number of failures is increased after multiple attempts, the accuracy of the failure count is ensured, and meanwhile, the situation that the information is sent too frequently due to the fact that the counting module is informed of the counting after each failure is avoided.

Optionally, the method further comprises:

when the number of continuous failures of network access by using the main network access parameter is larger than a threshold value, reporting log information to a network management system in a network, wherein the log information is used for indicating the failure of the access by adopting the main network access parameter.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In order to facilitate understanding of the technical solution provided in the embodiments of the present application, an application scenario of the present application is first introduced.

Fig. 1 is a schematic diagram of an application scenario provided in an embodiment of the present application. Referring to fig. 1, in this scenario there are included a Set Top Box (STB) 11, an optical network terminal (Optical network terminal, ONT) 12 (i.e. optical cat), a Router 13, a mobile terminal 14, an optical line terminal (Optical line terminal, OLT) 15, a broadband access server (Broadband Remote Access Server, BRAS) 16, an ethernet bearer internet protocol (Internet Protocol over Ethernet, IPOE) server 17, an authentication server 18 and a Core Router (CR) 19.

The set-top box 11 may be a television set-top box, and is configured to provide a television signal to a television; the optical network terminal 12 is an operator provided data terminal, which on the one hand can provide television signals to the set-top box 11 and on the other hand can provide network signals to the router 13, so that the router 13 can provide network signals to the mobile terminal 14; the optical line terminal 15, the broadband access server 16 and the core router 19 are devices in the operator line for transmitting the aforementioned television signal and network signal; the ethernet bearer internet protocol server 17 is configured to implement access of an ethernet bearer internet protocol of the set top box 11; the authentication server 18 is used for authenticating the set-top box 11 during the access of the set-top box 11.

The set-top box 11 may use IPOE, an ethernet bearer Point-to-Point protocol (PPPOE) or a dynamic host configuration protocol (Dynamic Host Configuration Protocol, DHCP) as a network access type to implement network access. For example, the network illustrated in fig. 1 may adopt an IPOE or a PPOE access manner, or may connect the set-top box 11 to the router 13 to implement DHCP access. Typically, the network access parameters of the set-top box are built in the set-top box, and the shipping process is uniformly configured. The network access parameters are related to customer networking, and are different in different networking modes, for example, the set top box is connected under an optical network terminal and a router, and the network access parameters are different.

The network access parameters of the set top box are stored locally in a file mode. The operator can remotely modify the network access parameters of the set top box through a network management system (Terminal Management System, TMS), and likewise, the user can locally log in the configuration page of the set top box to modify the network access parameters of the set top box. When the network access parameters are modified into error parameters, the error parameters can cover old parameter values and take effect, the set top box cannot acquire an IP address and register to a network management system, and the network access parameters become in a disconnection state, commonly called as brick change.

When the set top box cannot be used normally, a fault is reported through a service hot line (such as 10086), and the call center contacts a technician to output a technical recovery scheme after receiving the fault phenomenon, for example, remote guidance is used for modifying the configuration, or the set top box is maintained by going to the door. When the number of set top boxes is large and the number of reporting-impaired users is large, the scheme not only needs to waste a large amount of human resources, but also has low efficiency, uncontrollable recovery period and influence and easy initiation of large-area customer complaints.

Of course, other terminals similar to networking and having similar problems exist besides the set top box 11 in the application, for example, a discrete remote network element or a network element in the form of the internet of things, where the discrete remote network element may be an optical network device (Optical network terminal, ONT) or a router, and the network element in the form of the internet of things may be a vehicle-mounted terminal, intelligent furniture, intelligent screen, or the like.

Fig. 3 is a flowchart of a network access method provided in an embodiment of the present application. The method can be executed by the terminal in the application scenario, as shown in fig. 3, and comprises the following steps:

In the embodiment of the application, when the number of continuous failures of the access parameter of the main network reaches the threshold, the access is performed by adopting the access parameter of the standby network, and the access success of the access by adopting the access parameter of the standby network can be ensured because the access parameter of the standby network is backed up when the access is successful last time. Therefore, the problem that the terminal cannot acquire the IP address and register to the network management system after the network access parameters are modified into the error parameters and becomes an out-of-management state can be avoided. Meanwhile, the scheme does not need to be manually participated, a large amount of human resources are saved, the efficiency is high, and customer complaints are avoided.

Fig. 4 is a flowchart of a network access method provided in an embodiment of the present application. The method can be executed by the terminal in the application scenario, as shown in fig. 4, and comprises the following steps:

step S41: and acquiring the access parameters of the main network.

And when the terminal is started normally, reading the access parameters of the main network from the configuration file (setting.secure) of the terminal. The configuration file is physically stored in the terminal, for example under the iptv_data partition of the terminal. The active network access parameters in the configuration file may be modified by the user, TMS, etc.

Step S42: and adopting the main network access parameters to carry out network access. When the access with the active network access parameter is successful, step S43 is executed, and when the access with the active network access parameter is failed, step S44 is executed.

Step S43: and replacing the standby network access parameter by the main network access parameter.

In the embodiment of the present application, the network access parameters of the terminal are stored by using the database 4X. The database 4X stores two tables, a main data table and a standby data table, the main data table stores main network access parameters, the main network access parameters are the same as the main network access parameters in the configuration file, and the standby data table stores standby network access parameters. When the configuration file is modified, the active network access parameters in the active data table are synchronously modified so as to backup the active network access parameters in the configuration file.

Fig. 5 is a schematic structural diagram of a terminal provided in the present disclosure, referring to fig. 5, when network access is successful by using the primary network access parameter, a network access auxiliary module 4A of the terminal receives a network access status notification (which may be sent in a broadcast form) sent by a network module 4B, where the notification indicates that the access is successful. The network access auxiliary module 4A can write the primary network access parameter as a new standby network access parameter into the standby data table, so as to ensure the normal connection of the network when the network access parameter is switched to the standby network access parameter next time.

In this embodiment of the present application, the foregoing database 4X may be a light database, for example, an SQLite light database, where the SQLite light database has the characteristics of high flexibility, capability of storing a plurality of parameter values, convenient updating, and so on, and can well implement backup and read-write of network access parameters in this application.

In the embodiment of the disclosure, a software package (APK) may be built in the terminal, where the APK is configured to refresh the active network access parameter in the active data table to the standby data table when the active network access parameter is successfully accessed, so as to ensure dynamic refresh of the parameter.

In the embodiment of the disclosure, the active network access parameters and the configuration file can be modified by a user or a TMS system in real time, but the standby network access parameters cannot be modified, so that the accuracy and reliability of the standby network access parameters are maintained. And the triple insurance is formed by the mutual cooperation of the main network access parameter, the standby network access parameter and the configuration file, so that the continuous online of the terminal is ensured.

It should be noted that, in the initial state, the active network access parameters in the database 4X need to be read from the real-time network configuration of the terminal by the key parameter backup module 4C in the terminal, and then stored in the configuration file and the active network access parameters in the database 4X.

In the embodiment of the disclosure, the network access parameters include service parameters and service account information. Table 1 below shows by way of table an example of fields contained in the network access parameters in the present application:

In the embodiment of the present disclosure, the above threshold may be configured by a parameter in the terminal. For example, the parameter susist.hw.sys.net.bak.fail.max, which can be preset when leaving the factory, the value range [1,100], the default value is 5 times, and the parameter can be configured correspondingly according to the network requirement; the legal value is greater than 0 and less than or equal to 100, and the default value 5 is used when the illegal value does not exist or is not used.

The terminal is provided with a network access counting module 4D, and the network access counting module 4D counts by acquiring a network access status notification generated by the network module 4B in the terminal. When the terminal uses the main network access parameter to perform network access failure, generating a network access state notification indicating the access failure through a network module 4B in the terminal; and counting the number of continuous failures through a network access counting module in the terminal, wherein the network access counting module 4D accumulates a counting value based on the network access state notification indicating the access failure generated by the network module 4B, and the counting value is used for indicating the number of continuous failures. When the network access of the terminal is successful, generating a network access state notification indicating that the network access is successful through a network module 4B in the terminal; the network access counting module 4D resets the count value to 0 based on the network access status notification indicating that the access was successful generated by the network module 4B. That is, the count is performed when the notification indicates that the access has failed, and the count is cleared when the notification indicates that the access has succeeded. In addition to clearing the access success count, when the terminal is in standby, wakes up in standby, resumes factory setting, plugs network cables and the like, the continuous failure times are cleared.

In the embodiment of the present disclosure, the network access manner includes two modes of performing network access by using a single transmission protocol (i.e., single stack access) and performing network access alternately by using two transmission protocols (i.e., dual stack switching), for example, polling once "DHCP, PPPOE" or "PPPOE, DHCP" is a switching once. For the two connection modes, the counting mode is also different, and the network access counting module 4D may count in the following manner:

when a single transmission protocol is adopted for network access, each time of access failure generates a network access state notification indicating the access failure, and the count value of the network access counting module 4D is increased by one;

or when the two transmission protocols are adopted to alternately perform the network access, the network access state notification indicating the access failure is generated every time the number of periods (i.e. the switching times) for alternately performing the network access failure by adopting the two transmission protocols reaches the switching threshold value, and the count value of the network access counting module 4D is increased by one.

In the embodiment of the disclosure, when a single transmission protocol is adopted for network access, the switching flow is simpler, and only the switching is needed based on the threshold. When two transmission protocols are adopted to alternately perform network access, the switching threshold value needs to be considered besides the threshold value during switching, and the related parameters are as shown in the following table 2:

TABLE 2

The double stack_notify4failnum is used for controlling the time of failure to send the network access state notification indicating failure, and is only effective in the dual stack switching mode, and the first failure in the single stack access mode sends the network access state notification indicating failure.

In the embodiment of the present disclosure, processing logic when network access fails is as follows:

switching parameter source identification; the source of the switching parameters is switched every susist. Hw. Sys. Bak. Fail. Max times for a continuous failure

The processing logic of the conditions of successful network access or standby, standby awakening, factory setting recovery, network cable plugging and unplugging and the like is as follows:

mcontinuouslyfailcount=0; count of number of consecutive failures of/reset

mdoublestackrunnum=0; count of number of times of double stack of// reset

Since there are two access modes of single stack access and dual stack switching, there are several cases of the following table 3 when switching:

TABLE 3 Table 3

The dual stack switching procedure is described below by way of example. The scenario in this example is: the main network access parameter is double stack switching, the standby network access parameter is single stack access, and the related parameters are configured as follows:

double stack_retry_max=10// maximum number of swizzles, the maximum number of swizzles for dual stack is 10

persist. Hw. Sys. Bak. Fail. Max=5// threshold, switching primary and backup parameters with 5 consecutive failures

ethparam.source.switch.limit=10// switching threshold, primary and backup parameters are switched up to 10 times

The network access status notification indicating failure is sent by the 1 st failure when the doublestack_notify4 failnum=1// switch threshold is 1

Fig. 6 is a schematic diagram of a counting scheme of a terminal provided in the present disclosure, referring to fig. 6, in step S4a, dual stack switching access is performed by using a primary network access parameter, and when the number of continuous failures reaches 5, a primary-standby switching action is triggered; in step S4b, adopting the standby network access parameter to carry out single stack access, and triggering the primary-standby switching action when the continuous failure times reach 5 times; in step S4c, the dual stack switching access is performed by using the main network access parameter, and when the number of continuous failures reaches 5, the limit that the maximum number of dual stack switching is 10 is reached, and the connection is stopped.

Step S45: and acquiring standby network access parameters stored in the terminal.

In an embodiment of the present disclosure, this step may include: generating a network access parameter switching request;

the standby network access parameters are read from the database 4X based on the network access parameter switching request.

Here, generating the network access parameter switching request may include: acquiring a count value of a network access counting module 4D in the terminal; when the count value reaches the threshold value, a network access parameter switching request is generated by the network module 4B.

Illustratively, a network access parameter switching request is sent to a network access assistance module 4A by a network module 4B in the terminal, the network access assistance module 4A being configured to manage the database 4X; and acquiring the standby network access parameters read out from the database 4X by the network access auxiliary module 4A.

Illustratively, the network access assistance module 4A encapsulates the read-write operations of the network access parameters into a unified interface. The network module 4B obtains network access parameters through the interface instead, if the number of continuous failures counted by the network access counting module 4D reaches a threshold value, the network module 4B sends a network access parameter switching request, where the network access parameter switching request may be a broadcast message "android.net.data.network_backup_change", and notifies the network access auxiliary module 4A to switch the primary and secondary data sources. When the network access auxiliary module 4A receives the network access parameter switching request, data source switching is performed and the read network access parameter is returned to the network module 4B through the interface.

If the primary network access parameter is currently used, switching to the use of the standby network access parameter;

if the standby network access parameter is currently used, switching to using the active network access parameter.

Here, reading, by the network access assistance module 4A, the standby network access parameter from the database 4X may include:

changing the parameter source identification;

and reading the network access parameters corresponding to the modified parameter source identifiers from the database 4X to obtain the standby network access parameters.

In the embodiment of the present disclosure, the network access auxiliary module 4A may determine the network access parameters to be read according to the parameter source flag in the terminal. The parameter source flag sys.hw.net.eth.param.source is used for identifying whether the parameters used for the network connection are read from the standby network access parameters or the active network access parameters, and the range of the parameter source flag is 0 and 1. If the value is 0 or does not exist, the use of the 'active network access parameter' is indicated; a value of 1 indicates the use of a "standby network access parameter".

The network access auxiliary module 4A reads corresponding data according to the parameter source mark:

if the identification is that the access parameter of the active network is used, the data in the configuration file can be read according to the step S41; of course, the access parameters of the main network in the database can also be read;

and if the identification is that the standby network access parameter is used, reading the standby network access parameter.

The parameter source mark is only recorded in the memory, and the main network access parameter is preferentially used for network connection after the system is restarted, so that the main network access parameter meets the intention of an operator only when the main network access parameter and the standby network access parameter are available.

In addition, after the network is successfully counted, the continuous failure count needs to be cleared, but the parameter source identifier needs to be reserved so as to be used as a reference in the next network access. Similarly, under the conditions of standby wakeup, network cable plugging and the like, the parameter source identification is kept unchanged, and the parameter source identification before continuous use is carried out.

When the network access fails, when the number of continuous failures is larger than a threshold value, modifying the mark of the parameter source so as to use the parameter of the new source when the network access is next time, namely realizing switching:

If the primary network access parameter is currently used, modifying the identification as the use standby network access parameter;

if the standby network access parameter is currently used, the active network access parameter identified as being used is modified.

Optionally, the method may further include:

After receiving the network access parameter switching request, the network access auxiliary module judges whether the network access auxiliary module is the first switching after power-up/restarting, if so, the network access auxiliary module reports log information to the TMS, and if not, no additional processing is needed.

The log information may be sent via a broadcast message, for example:

reporting 10024 error CODEs through broadcasting message android.intent.action.error_code_report, and carrying error CODE information by using info field, wherein the error CODE information is as follows:

{"ErrorCodeValue":"10024",

"ErrorSource" 1",// means first hand-off

"ErrorDesc":"Network last-access to use backup network parameters"}

"ErrorDesc" enable standby network Access parameter "

Step S46: and adopting the standby network access parameters to carry out network access. When the access with the standby network access parameter is successful, step S47 is performed. When the access using the standby network access parameter fails, step S48 is performed.

In the access process, the user may change the networking scheme, for example, change the terminal from being connected to the optical network terminal to being connected to the router, so that although the network access parameter is adopted when the last access is successful, the access failure is caused by the change of the networking scheme when the standby network access parameter is adopted.

Step S47: and writing the standby network access parameters into a main data table to serve as the main network access parameters.

When the standby network access parameter is successfully accessed, the network access auxiliary module 4A of the terminal receives a network access status notification sent by the network module 4B, the notification indicates that the access is successful, and at this time, the network access auxiliary module 4A can write the standby network access parameter into the main data table and the configuration file in the database.

Step S48: and recording the continuous failure times of network access by adopting the standby network access parameters. When the number of consecutive failures is greater than the threshold value, step S41 is performed.

When the adoption of the standby network access parameter fails, the standby network access parameter can be switched to the main network access parameter, and multiple attempts are made to avoid unsuccessful access under the condition that the network access parameter is correct.

Optionally, the method may further include: and stopping network access when the primary and standby switching times reach a switching threshold value.

In the embodiment of the present disclosure, the switching threshold ethparameter. The switching threshold value range [1,10000] is 10 by default, and the configuration item does not exist or the value is not a default value for rules.

When receiving a network access parameter switching request, the network access auxiliary module 4A judges whether the switching times reach a switching threshold value;

if not, continuing accumulating and switching the data sources; if the threshold has been reached, the data source is not switched. The count is the same as the continuous failure times, and is reset when the terminal is restarted, wakes up in a standby mode, plugs in and plugs out the network cable and is accessed successfully, and other conditions are continuously accumulated.

According to the method and the device, the continuous failure times of network access are counted, and when the times reach the threshold value, the network access parameters used are switched seamlessly, so that the continuous online of the terminal is ensured.

The network access parameter backup and switching scheme adopted in the embodiment of the disclosure can be selected to be started or not started in the terminal.

For example, whether to turn on the function is determined by setting values of the following parameters of the terminal: the value range of the parameter is [0,1], wherein, the value of 0 or unset value indicates that the function is not started; a value of 1 indicates that the function is turned on.

The terminal comprises a setup module 4E which provides a User Interface (UI) for the User, through which the User can make data modifications and queries.

In general, in the user interface, all the active network access parameters are displayed, and after the parameter source identifier is introduced, there may be a problem that the network access parameters displayed in the user interface are not matched with the network access parameters used by the network module 4B.

Although the general user does not care what parameters are used by the current network module 4B to access the network, only the terminal needs to access the network. It is necessary for maintenance personnel to know which parameters the terminal is currently using to access the network in order to discover problems in advance or locate problems that have occurred. Thus, we add the network access parameter information option to the [ more ] menu of the user interface, including the current network access parameter source-enabled standby network access parameters in table 4 below.

TABLE 4 Table 4

The network access parameter information options can be displayed by default and can be closed as required.

When the parameter source identifier sys.hw.net.eth.parameter source takes a value of 1, the current network access parameter source is a standby network access parameter, and the "enabled standby network access parameter" is displayed; and the value is not existed or is 0, and the active network access parameter is enabled. The user may click on this option to enter the details page to view the relevant network access parameter information.

The decision of which data to display is based on the current network access mode (DHCP/IpoE/PPPoE/Static), the ethernet_mode field in the network access parameters indicates which access mode the network is currently using. Table 5 below shows the parameters in three modes IpoE/PPPoE/Static.

Considering the above [ more ], the information of the current network access parameter source is only used in the process of maintaining, observing and positioning the network problem, the parameter source identifier is stored by adopting a system attribute, and the user interface cannot know the change of the system attribute value in real time, so that the user interface cannot be updated in real time. The method and the device can be used for refreshing the parameter source identification by reentering after returning to the upper page.

TABLE 5

Fig. 7 is a flowchart of a network access method provided in an embodiment of the present application. The method can be executed by the terminal in the application scenario, as shown in fig. 7, and includes the following steps:

step S51: and receiving a one-key rollback instruction sent by the network management system.

And the terminal is internally provided with a device.X_00E0FC.ParameterRestore function, and when the terminal receives an instruction device.X_00E0FC.ParameterRestore=network.ConnectType issued by a network management system (TMS), the terminal executes a one-key rollback function.

The one-touch back instruction may indicate that the parameter before the modification needs to be returned after the modification.

Step S52: at least one modified parameter is determined from the standby network access parameters.

The terminal recognizes the device. X_00e0fc.parameterrestore instruction through the middleware configuration management module, and then performs the following operations:

inquiring whether the recovery parameter HwParmName (the parameter can be any parameter in network access parameters) to be recovered has a backup field HwParmName_bak, if not, ending the operation, and returning to failure; if so, the parameter HwParmOldValue is obtained and step S53 is performed.

Here, the standby network access parameters stored in the terminal may be stored in the manner of the previous step S43.

Step S53: and adopting the parameters obtained from the standby network access parameters to carry out network access.

Updating the HwParmOldValue into a parameter field HwParmName, and recovering the parameter field state in the database after completion:

HwParmName_bak: this field stores the value HwParmOldValue before modification;

HwParmName: the value stored in this field is the same as the backup field HwParmOldValue.

Meanwhile, the method may further include: and refreshing the main data table in the terminal by adopting the standby network access parameters to perform reverse writing, so that the follow-up acquisition of the parameters from the main data table can be ensured to be online.

Fig. 8 is a schematic diagram illustrating a process of adopting a one-key rollback function, as shown in fig. 8, when an operator modifies a network access parameter of a terminal through a network management system and if an error parameter is modified due to misoperation, and a failure that cannot be logged in is caused, one-key rollback can be implemented through the steps to refresh the parameter, so that the terminal is recovered to be normal, and the terminal is prevented from being offline due to misoperation.

After this step, steps S45-S47 may also be continued.

In addition to performing the one-key fallback in the manner of steps S51-S52, the method may also perform the one-key fallback in the following manner: directly modifying network access parameters through issuing parameters SetParameterValues (parameter names, parameter values), and supporting parameters of issuing one-key rollbacks are as follows in table 6:
