Embodiment 1

FIG. 1 is a schematic flowchart of a method for synchronizing a terminal capability information according to an embodiment of the present invention. As shown in FIG. 1, the method includes:

Step 101: The server acquires terminal capability change information.

Here, the server acquiring the terminal capability change information may be the server receiving the terminal capability change information reported by the terminal; or the server may detect that the terminal network capability changes, and obtain the terminal network capability change information; or the server receiving the communication system reporting The terminal capability change information obtains the terminal network capability change information.

The server detects that the terminal network capability changes to: detect a communication link between the server and the terminal, and determine that the terminal network capability changes when the communication link changes.

Here, the terminal reporting the terminal capability change information includes: when the terminal capability is changed, the terminal determines whether the terminal capability change information needs to be reported to the server according to the preset constraint conditions, and reports the terminal capability change information when determining that the report needs to be reported.

Here, the constraint conditions include, but are not limited to, one or more of a service type, a terminal capability and a service association degree, a type of a terminal, a level of a terminal, a security level of the terminal, and a level of the terminal user.

Here, the terminal determines whether the terminal capability change information needs to be reported to the server according to the preset constraint conditions, specifically: the terminal determines, according to the preset service constraint condition, whether the terminal and the current service meet the constraint condition, and satisfies the service condition. When the constraint is met, it is determined that the terminal capability information is reported to the server.

Here, the terminal capability information includes terminal local capability information and terminal network capability information. Correspondingly, the terminal capability change information includes: terminal local capability change information (information indicating terminal local capability change) and terminal network capability change information (representing terminal) The information of the network capability change), the terminal local capability change flag bit and the terminal network capability change flag bit may be set in the terminal capability change information;

The terminal local capability changes, including but not limited to one or more of the following: 1) The user switches the operating system;

2) The user adds hot plug devices, accessories and peripherals to the terminal;

3) The user unloads the hot-swappable device, accessories and peripherals from the terminal;

4) The user installs or uninstalls the application software and the driver on the terminal;

5) When the business or application running on the terminal is closed;

6) The user of the terminal has changed.

The terminal network capability changes, including but not limited to one or more of the following:

1) The terminal increases the network access path;

2) The terminal reduces the network access path;

3) The network access mode of the terminal changes.

Here, the server and the terminal communicate through a communication link, and the server may be a server in a traditional sense or a virtual server using a cloud computing technology; the terminal is a device having a user interface and communication capability, including a mobile phone, a game machine, The main function of the desktop computer, the notebook computer, the television, the music player and the server is to directly interact with the user and present the service to the user, and the user interface can be an input/output interface.

Here, the terminal local capability and the terminal network capability change may be learned by the terminal self-test. When the terminal initiates a service to the server, the terminal runs a self-test program provided by the server, and the self-test program may preset a constraint condition, and The terminal capability is monitored, and the local capability information collection of the terminal is completed, and the terminal capability change information is generated and reported to the server when the preset constraint condition is met.

Step 102: The server determines the terminal capability information that needs to be reported by the terminal according to the preset constraint conditions, and sends a request message to the terminal, requesting terminal capability information that needs to be reported;

The identifier of the software may be a software unique number, and the service level includes a security level and a copyright protection level. , run priority.

The service software is software that has a unique identifier and can perform a specific function, and the identifier can be a name and a version number.

The requirement of the service to run the carrier capability is that the running of the service requires the most basic hardware and software resources of the running carrier. The terminal list is a summary of related information of each terminal, including a terminal type, a model of the terminal, a terminal manufacturer, a terminal unique identifier, a terminal level, and a terminal capability, and the terminal list is to follow a specific format, and the format is determined by the service provider. The server manufacturer, the terminal manufacturer, and the like parties agree in advance that the terminal level includes a security level and an operation priority. Here, the adjustment of the current service running policy requires obtaining the current service carrying capacity requirement and the service level information through the service list, and performing the policy according to the terminal capability information reported by the terminal and other capability information of the terminal in the terminal list. Adjust the operation.

The operation of the service adjustment by the server includes performing a service division between the server and the terminal according to the change of the local capability of the terminal, and adjusting the service communication manner according to the change of the network capability of the terminal.

Here, when the service adjustment requires the user to confirm, the service negotiation may be performed with the user, and after the user confirms the adjustment, the service adjustment is performed. For example: When the terminal leaves the Wi-Fi network coverage, the user can be notified to choose whether to switch to the cellular network to continue the service, and switch the network when the user confirms to continue the service.
