It should be understood that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the present invention shown in FIG. 1 provides a method for restoring a terminal configuration, including: Step 101: Sending configuration information of a recovery terminal configuration to a terminal, where the setting information includes a level or/and a policy for restoring the terminal configuration. The level or/and policy is used to indicate the extent to which the terminal resumes configuration.

The terminal configuration is restored, that is, the configuration information of the terminal is restored to the level or/and the state indicated by the policy. The setting information is transmitted through a management channel between the terminal and the terminal management system. The management channel is at least one, to complete data transmission between the terminal and the terminal management system, where The uplink and downlink data transmission between the terminal and the terminal management system may use the same management channel or different management channels, which is not limited herein.

Wherein, before step 101, the following steps may be further included:

Presetting the level or/and policy of the recovery terminal configuration; determining a level or/and a policy of the recovery terminal configuration from the level or/and policy, adding the determined level or/and policy to the setting Information.

The sending of the setting information in the step 101 may be performed by an entity that manages the configuration information of the terminal, such as the terminal management system. In the embodiment of the present invention, the terminal management system is taken as an example.

After the terminal management system sends the setting information to the terminal, the terminal management system waits for the terminal to return the response information; the terminal receives the setting information, and after the configuration is restored according to the setting information, sends a response message to the terminal management system to notify the terminal management system. The configuration has been completed and the terminal management system can be configured for the service.

The terminal management system receives the message that the terminal responds to; configures the service of the terminal according to the configuration template of the service to be delivered, so that the service function is provided.

According to the technical solution provided by the embodiment of the present invention, the terminal management system may preset a level or a policy for restoring the terminal configuration according to the configuration requirement, or set a policy for restoring the terminal configuration while setting a level for restoring the terminal configuration, so that The terminal management system may enable the terminal to manage the terminal according to the level or/and policy of the recovery terminal configuration, and control the degree of the configuration of the recovery terminal. When the terminal needs to be configured, the terminal may restore the terminal to the desired or desired location of the terminal management system. The required state, reducing the number of configuration of the terminal.

The recovery terminal configuration can be performed in three ways. The first method is to restore the terminal configuration according to the level of the recovery terminal configuration. Correspondingly, the setting information of the recovery terminal configuration includes: restoring the level of the terminal configuration; Recovering the terminal configuration according to the policy of the recovery terminal configuration, correspondingly, the setting information includes a policy for restoring the terminal configuration; the third manner is to combine the first two modes according to the level of the recovery terminal configuration and the recovery. The policy of the terminal is configured to restore the terminal configuration. Correspondingly, the setting information includes a level and a policy for restoring the terminal configuration. Next, the technical solution of the method provided by the embodiment of the present invention will be described in detail in the form of an embodiment in combination with the above three ways of restoring the terminal configuration.

Embodiment 1 The terminal configuration is restored according to the level of the recovery terminal configuration.

In the first embodiment, the degree of recovery of the terminal configuration is controlled by restoring the level of the terminal configuration. The setting information of the configuration of the recovery terminal can be transmitted by using the ResetCPEByLevel method. The format of the ResetCPEByLevel method is as shown in Table 1. The parameter iLevel identifies the level of the recovery terminal configuration.

Table 1: Format of the ResetCPEByLevel method

The number of recovery levels configured by the terminal can be specifically set according to the actual application environment, which is not limited herein. For example, it can be divided into the following three types:

At the first level, the recovery terminal is configured to a manageable state. In other words, it is only necessary to retain the information of the terminal configuration to the extent that the terminal management system can manage it. When the terminal is restored to the level, the terminal is a clean terminal for the terminal management system, and the terminal management system can configure the terminal without concern for the pre-configured state of the terminal. The pre-configured state of the terminal mentioned here is Refers to the existing configuration information before the terminal management system configures the terminal;

The second level restores the terminal configuration to the last correct configuration state. That is to say, when the terminal cannot be used due to some misconfiguration error, the configuration information of the terminal can be restored to the state before the error, so that the terminal is available, and the terminal can be restored again. The original configuration information of the terminal can ensure that the terminal can restore the existing service capability. The third level restores the configuration of the terminal to the factory configuration state. That is, the terminal is completely restored, and its configuration state is the same as the factory configuration state. The operation process of the method is shown in FIG. 2, and the specific steps include:

Step 201: The terminal sends the information: that is, when the terminal goes online, the terminal sends the information to the terminal management system, and informs the terminal management system that the terminal is online.

Step 202: The terminal management system responds to the reporting information of the terminal: after receiving the reporting information, the terminal management system confirms that the terminal is online, returns a response message to the terminal, and informs the terminal that the terminal management system knows that the terminal is online.

Step 203: The terminal management system sends a ResetCPEByLevel (1) method: After responding to the terminal information, the terminal management system sends a ResetCPEByLevel (1) method to the terminal regardless of the state of the existing configuration of the terminal.

Through the delivery of the ResetCPEByLevel (1) method, the terminal can be restored to a manageable state under the control of the terminal management system, so that the configuration information of all terminals can be the same regardless of the original configuration information. The terminal management system does not need to care about the original configuration information of each terminal. For a service, the terminal management system can use only one configuration template corresponding thereto, and all the online terminals can be configured through the configuration template, so that the online terminal With this business function, the number of configurations is reduced, and the working efficiency of the terminal management system is improved.

Step 204: The terminal resumes the configuration, and the management channel is reserved. After receiving the ResetCPEByLevel (1) method sent by the terminal management system, the terminal recovers according to the level of the recovery terminal configuration indicated in the ResetCPEByLevel (1) method. The terminal is configured to a manageable state, and a management channel (management PVC) is reserved for the terminal management system.

Referring to the description of step 101, at least one management channel exists between the terminal and the terminal management system. When the configuration of the terminal is restored in this step, for example, when the configuration of the terminal is restored according to the second level or the third level, A parameter corresponding to the management channel may be deleted under the control of the terminal management system. At this time, the management channel between the terminal and the terminal management system is unavailable, and communication between the subsequent terminal and the terminal management system cannot be performed. The reserved management channel described in this step is intended to emphasize that in the terminal recovery configuration, at least one management channel must be reserved between the terminal and the terminal management system, so that the terminal management system can perform other configuration operations on the terminal. Provide communication guarantee for the terminal to accept terminal management system management and configure business functions.

Step 205: The terminal sends a response message to the terminal management system: After the terminal reserves a management channel for the terminal management system, the terminal sends a response message to the terminal management system.

The response message is used to inform the terminal management system that the terminal has returned to a manageable state and can be managed by the terminal management system.

Step 206: The terminal management system receives the response message, and performs service configuration: after receiving the response message, the terminal management system learns that the terminal is ready, and can start to send a service operation, so the terminal management system receives the response message. Then, according to the configuration template of a certain service, according to the configuration template, the configuration process of the service is started, and the service function configuration of the terminal is completed, that is, the terminal is configured, so that the terminal has the service function.

The above operation step is that the terminal management system performs the first level restoration configuration on the terminal, and completes the service function configuration on the terminal.

It should be noted that the operation process of performing other levels of restoration configuration on the terminal is the same as the recovery operation of the first level described above. The application scenario of the third-level recovery configuration of the terminal (that is, the method of calling the ResetCPEByLevel (3)) is the same as the above-mentioned first level, that is, the terminal management system can recover the existing configuration information of the terminal without worrying about the terminal; The second-level recovery configuration (and the call to the ResetCPEByLevel (2) method) is mainly used to make a fault in the service configuration of the terminal. For example, if a terminal has access to the Internet, if the user needs to activate the IPTV service, the IPTV is sent in the terminal management system. If there is an error during the service, you can call the ResetCPEByLevel ( 2 ) method to restore the terminal to the Internet-enabled state, and then you can configure the terminal for other configurations.

In addition, if the terminal has a certain service function before the terminal is restored, and the terminal management system wants the terminal to retain the configuration information corresponding to the service when the configuration is restored, the terminal management system needs to correspond to the service. The configuration template is sent to the terminal as a parameter, and the terminal is notified that all configuration items of the service are retained according to the configuration template corresponding to the service when the configuration is restored. In Embodiment 1, the terminal management system sets the level of the recovery configuration for the terminal, indicates the degree of recovery configuration required by the terminal, and controls the terminal to restore the configuration to the desired state of the terminal management system (such as the manageable state, the last correct configuration state). , factory configuration status, etc., greatly improving the flexibility of configuration, while maintaining the manageability of the terminal management system to the terminal; and, the terminal management system controls the terminal to restore the configuration to the desired state of the terminal management system, so that the terminal can be retained If the parameters are successfully configured, the configuration parameters are not required to be completely restored, and the configuration parameters are re-issued, thereby reducing the number of times the terminal management system configures the terminal and improving the working efficiency of the terminal management system.

Further, after the terminal management system restores the configuration of the terminal, the configuration status of all the online terminals is in a unified state, avoiding the problem that the existing configuration information of the terminal or the factory configuration is inconsistent, and the terminal pre-configuration information or the factory configuration is solved. The management problems caused by the inconsistency reduce the number of configurations, improve the working efficiency of the terminal management system, and further increase the scope of application of the terminal.

Embodiment 2: Restore the terminal configuration according to the policy of the recovery terminal configuration.

In the second embodiment, the technical solution of the method is to control the degree of recovery of the terminal configuration by a policy of the recovery terminal configuration, and the setting information of the recovery terminal configuration may be implemented by using the ResetCPEByStrategy method, and the ResetCPEByStrategy method. The format is shown in Table 2.

Table 2: Format of the ResetCPEByStrategy method

The input parameter is used to identify the degree of recovery of the terminal configuration, that is, the policy of the recovery terminal configuration is carried by the input parameter; the input parameter may be an Xml (Extensible Markup Language) file, or a configuration template. The policy can be described as: recovery terminal Configuration information that needs to be retained at the time of setting, for example, configuration items that need to be reserved (such as configuration items when the IPTV service is activated), and/or configuration information that needs to be deleted when the terminal configuration is restored, and the like. When restoring the terminal configuration, the terminal selectively restores the configuration according to the policy, specifically, according to the information described by the Xml file or the configuration template.

The operation process of the method is shown in FIG. 3, and the specific steps include:

Step 301: The terminal sends the information: that is, when the terminal goes online, the terminal sends the information to the terminal management system to inform the terminal management system that the terminal is online.

Step 302: The terminal management system responds to the reporting information of the terminal: after receiving the reporting information, the terminal management system confirms that the terminal is online, returns a response message to the terminal, and informs the terminal that the terminal management system knows that the terminal is online.

Step 303: The terminal management system sends a ResetCPEByStrategy method: After responding to the reported information of the terminal, the terminal management system sends a ResetCPEByStrategy method to the terminal.

Through the delivery of the ResetCPEByStrategy method, the terminal can be restored to the state indicated by the ResetCPEByStrategy method under the control of the terminal management system. In this way, the configuration information of all terminals can be the same after being configured, and the terminal management system does not need to care again. The original configuration information of each terminal, for a service, the terminal management system can use only one configuration template corresponding thereto, so that all online terminals can be configured through the configuration template, so that the online terminal has the service function, and the number of services is reduced. The number of configurations increases the efficiency of the terminal management system. While restoring the terminal configuration, the terminal can selectively retain some configuration information of the terminal according to the input parameters of the ResetCPEByStrategy method (such as Xml files, configuration templates, etc.). Keep some business functions.

Step 304: The terminal resumes the configuration, and the management channel is reserved. After receiving the ResetCPEByStrategy method sent by the terminal management system, the terminal restores the terminal configuration to the state indicated by the ResetCPEByStrategy method according to the configuration information of the recovery terminal configuration indicated in the ResetCPEByStrategy method. After that, a management channel (management PVC) is reserved for the terminal management system.

Referring to the description of step 101, there is at least one between the terminal and the terminal management system. When the configuration of the terminal is restored in this step, for example, when the configuration of the terminal is restored according to the second level or the third level, a parameter corresponding to the management channel may be deleted under the control of the terminal management system. At this time, the management channel between the terminal and the terminal management system is unavailable, so that communication between the subsequent terminal and the terminal management system cannot be performed; the reserved management channel in this step is intended to emphasize that in the terminal recovery configuration, At least one management channel must be reserved between the terminal and the terminal management system, so that the terminal management system can perform service configuration operations on the terminal, and provide communication guarantee for the terminal to accept the service delivered by the terminal management system.

Step 305: The terminal sends a response message to the terminal management system: After the terminal reserves a management channel for the terminal management system, the terminal sends a response message to the terminal management system.

The response message is used to inform the terminal management system that the terminal has recovered to the state indicated by the ResetCPEByStrategy method, and can accept the management of the terminal management system.

Step 306, the terminal management system receives the response message, and performs service configuration: the terminal management system receives the response message, that is, learns that the terminal is ready, and can start to deliver the service operation, so the terminal management system receives the response message. Then, according to the configuration template of a certain service, according to the configuration template, the configuration process of the service is started, and the service function configuration of the terminal is completed, that is, the terminal is configured, so that the terminal has the service function.

In the second embodiment, the terminal management system delivers a policy for restoring the configuration to the terminal in the manner of, for example, an Xml file, indicating the extent to which the terminal needs to restore the configuration, thereby selectively controlling the configuration items required for the terminal to be restored, thereby greatly improving the configuration. Flexibility, while maintaining the manageability of the terminal management system to the terminal; restoring the terminal to the desired level of the terminal management system, reducing the number of configurations and improving the configuration efficiency of the terminal management system.

Embodiment 3: Send, to the terminal, setting information of restoring the terminal configuration according to the level and policy. In Embodiment 3, the technical solution of the method is to control the degree of recovery of the terminal configuration by restoring the level of the terminal configuration and the policy of the recovery terminal configuration, and the setting information of the configuration of the recovery terminal may be sent through the ResetCPEForDiff described below. Method implementation, the format of the ResetCPEForDiff method is as shown in Table 3. There are two input parameters, and the int Level identifies the level of the recovery terminal configuration. Object oXmlFile identifies the description file of the basic configuration that needs to be preserved when restoring the terminal configuration. The terminal needs to retain the configuration items described in the configuration file Object oXmlFile while restoring the configuration according to the level of the recovery terminal configuration. For example, the level of the configuration of the recovery terminal is the first level, and the object oXmlFile describes the configuration item when the IPTV service is enabled. When the terminal restores the configuration, the terminal must retain the configuration item corresponding to the IPTV service and the configuration item of the manageable state, that is, the terminal. The IPTV service function and manageability function need to be reserved, and other configuration items can be selectively reserved or deleted.

Table 3: Format of the ResetCPEForDiff method

In Embodiment 3, the setting of the level is similar to that of Embodiment 1, and the policy is formulated similarly to Embodiment 2. The operation procedure of Embodiment 3 is similar to Embodiment 1 (or Embodiment 2), and is no longer Narration.

For a terminal that fails during the configuration process, if the configured configuration item can be retained during the recovery process, the terminal management system can reduce interaction with the terminal. If you upgrade according to a certain strategy, you can tell the terminal through the xml file that you need to keep those configuration items during recovery.

The number of interactions that the terminal management system interacts with the terminal during the management of the terminal will affect its performance. When the number of terminals reaches a certain value, if the interaction with the terminal can be minimized, the performance of the terminal management system can be greatly improved.

In the third embodiment, the terminal management system, in combination with the level and policy of the recovery terminal configuration, indicates the extent to which the terminal needs to restore the configuration, and can more effectively control the degree that the terminal restores to the terminal management system, thereby greatly increasing the configuration. Flexibility, while maintaining the manageability of the terminal management system to the terminal, and reducing the number of configurations, improving the configuration efficiency of the terminal management system.

The embodiment of the invention further provides a method for configuring a terminal, and a flowchart of the method is shown in FIG. 4, and the specific operation steps include: Step 401: Receive setting information of a recovery terminal configuration sent by the terminal management system, where the setting information includes a level or/and a policy for restoring the terminal configuration, where the level or/and the policy is used to indicate the degree of the terminal to restore the configuration.

Step 402: Restore the configuration according to the setting information of the recovery terminal configuration.

After the operation of restoring the terminal configuration is completed, at least one management channel is reserved between the terminal management system and the terminal, and the terminal sends a response message to the terminal management system through the management channel, where the response message is used to notify the terminal management system that the terminal has The configuration state of the terminal is restored to the state required by the terminal management system; the terminal management system receives the response message, starts the service configuration process, and then starts to deliver the service to the terminal, so that the terminal has the service function.

The embodiment of the terminal configuration method is similar to the related description in the embodiment of the recovery configuration method, and details are not described herein again.
