Step 201: Acquire feature information of the user terminal, where the feature information includes at least one of user information, user terminal information, and user bandwidth information. The user information includes at least a user identifier and a user status, and the user terminal information includes at least a terminal. Type, resolution, and player video format, the user bandwidth information includes the user bandwidth. It should be noted that the user identifier is used to identify the user terminal. For example, the user identifier 0001 corresponds to the user terminal 1, and the user status refers to the user terminal being connected. The state is still disconnected, etc.; the terminal type can know the resolution and player video format supported by the terminal type. The terminal type may be identified by a terminal identifier similar to 1, 2, etc. indicating the terminal type. For example, when the terminal identifier is 1, the terminal is identified as iphone.

Specifically, the content network function entity CN-FE of the CDN acquires a MBB (Mobi le Broadband) network entity GGSN (Gateway GPRS Support Node) or a PCRF (Poly icy and Charging Rule Function) Rule function) actively reporting the feature information of the user terminal;

Alternatively, the CN-FE sends a feature information request command to the GGSN or the PCRF, and receives a response message of the feature information request command returned by the GGSN or the PCRF, where the response message includes the feature information of the user terminal;

The GGSN reports the feature information of the user terminal to the CN-FE through the first preset interface, where the first preset interface can be manually configured, or can be an existing communication channel or a new communication channel; The device can report the feature information of the user terminal to the CN-FE. The second preset interface can be manually configured, or can be an existing communication channel or a new communication channel.

It should be noted that, before this step, the user terminal reports the user information and the user terminal information to the GGSN and the PCRF of the MBB network when accessing the MBB network for the packet data protocol PDP activation; and the GGSN and the PCRF perform policy decision interaction. During the process, user bandwidth information will be agreed upon.

Step 202: Receive an access request of the user terminal.

Specifically, the CN-FE receives an access request forwarded by the MBB network TCCF (Traffic Cache Control Function) function module sent by the user terminal; where the TCCF function module detects the access request sent by the user terminal, and according to The preset rule is used to determine whether to send the detected access request to the CN-FE. The preset rule includes a preset forwarding rule or a forwarding rule generated by dynamic detection. For example, the preset forwarding rule is: Access requests to the top ten websites are forwarded to the CN-FE, where the TCCF can be implemented in the GGSN, the straight DPI device, the bypass DPI device, or the standalone TCCF device; Step 203: Determine whether the content requested by the access request is saved, if yes, go to step 205, if not, go to step 204;

Step 204: Send the access request to the Internet source server, the Internet source server sends the content to be accessed by the access request to the CDN network entity, the CDN network entity saves the content requested by the access request, and performs step 205;

Step 205: Adjust and adapt the content to be accessed by the access request according to the acquired feature information, so as to conform to the setting of the user terminal;

Specifically, the access content of the user terminal is converted into content that matches the user information, the user terminal information, and the user bandwidth information; and at least includes one of the following methods:

1), when the feature information is user information, performing access control on the accessed content according to user information, so that it conforms to the state of the user terminal;

Specifically, the user terminal is controlled according to the user information, such as the user identifier and the user status; for example, the user identifier and the current user status of the user terminal corresponding to the user identifier are in a connected state, that is, the user is accessing the content, However, due to an abnormality in the network, the user terminal is disconnected and the access breakpoint of the user terminal is saved. When the user state becomes the connected state again, the access to the content can be continued from the saved breakpoint without having to start from the beginning.

2), when the feature information is user terminal information, adjusting an attribute of the accessed content according to the user terminal information to conform to the setting of the user terminal;

Specifically, the video format and resolution of the content to be accessed are automatically adapted according to the terminal type, the player video format, and the resolution in the user terminal information, so as to meet the user requirements; for example, the terminal type is iphone, then the user can know The iphone does not support the flash video format, and the flash video that is required to be accessed is converted into a playback format supported by the iPhone device, such as: avi format, and the access request is to access a flash video, then the flash needs to be accessed. The video is converted to the video in avi format and sent to the user terminal, so that the user terminal can successfully display the video; for example, the screen resolution supported by the user terminal is 480*320, and the resolution of the access screen required by the access request is 1624*. 768; The resolution of the picture requested to be accessed is adjusted to 480*320, and then the picture is sent to the user terminal, so that the user terminal can successfully display the picture;

3), when the feature information is user bandwidth information, adjusting, according to the user bandwidth information, the transmission rate of the accessed content to conform to the bandwidth condition of the user terminal.

Specifically, according to the user bandwidth information, adaptive processing is performed on the content to be accessed, such as comprehensive adjustment and transcoding of the frame size, frame frequency, and frame quality of the video content, adapting the user bandwidth, and according to the large file to be accessed. The user bandwidth determines the download speed, etc.; for example, the user bandwidth information is 500 Kbps, and the encoding content rate of the accessed content, such as the video content, is 2 Mbps, and the encoded code rate of the content to be accessed is transcoded to 500 Kbps and then sent to the user terminal to enable the user. The terminal better receives and displays the accessed content;

In addition, when the network bandwidth changes, such as when the network is congested or the event is switched from the 3G network to the 2G network, the PCRF sends a policy to change the user bandwidth. In this case, the GGSN or PCRF needs to send the user to the CN-FE. The bandwidth update information, CN-FE adaptively transcodes the Internet content according to the latest user bandwidth information, and achieves an adaptive process adjusted according to network changes.

Step 206: Send the content processed by the matching to the user terminal, so that the user terminal obtains the content that matches the format of the user.

The technical solution provided by the embodiment of the present invention has the beneficial effects that: by adjusting and adapting the access content according to the obtained feature information, and implementing the technical solution of transmitting the adjusted content to the user terminal, The returned access content matches the setting of the user terminal, so that the user terminal can normally display and play the accessed content, and improve the user experience.
