Embodiment 1

[0044] This embodiment provides a content compression method, which is suitable for deployment in such as figure 2 On the service gateway in the scenario shown, refer to figure 2 , wherein the Cache system entity can be connected to multiple service gateways for interaction and linkage to complete the compression function; the service gateway can be connected to the Cache system entity, and can also be directly connected to content sources on the Internet to directly obtain data content.

[0045] Such as image 3 As shown, the method includes:

[0046] Step 101, the service gateway receives a user access request sent by a user terminal, and the user access request is specifically an HTTP GET request.

[0047] Step 102, the service gateway searches for corresponding compression level decision information according to the received user access request.

[0048] Since user subscription information, service QoS requirements, user location information, time information, etc. ca...

Embodiment 2

[0065] This implementation specifically provides a content compression method, such as Figure 5 (Indicates that the Cache system entity finds the requested data content) or 6 (Indicates that the Cache system entity does not find the requested data content), the method includes:

[0066] Step 300, the user terminal sends a user access request to the service gateway;

[0067] Step 301, the service gateway searches for the user's service QoS level, user level and other compression level decision information stored locally according to the user identification in the received user access request;

[0068] Step 302, the service gateway determines the compression level of the user access request according to the compression level decision information and preset decision rules;

[0069] In this embodiment, the specific form of the decision rule preset on the service gateway may be a decision table, as shown in Table 1 below

[0070]

[0071] Table I

[0072] Specifically, with ...

Embodiment 3

[0087]This embodiment provides a content compression device, which may be a content compression device on a service gateway, or may be a service gateway, so as to facilitate the realization of the method of the service gateway in the above-mentioned embodiment 1 or 2. Such as Figure 7 As shown, it includes: a receiving module 40 , a searching module 41 , a determining module 42 , an inserting module 43 , and a sending module 44 .

[0088] The receiving module 40 is used to receive the user access request sent by the user terminal; the search module 41 is used to find the corresponding compression level decision information according to the received user access request; the determination module 42 is used to determine the compression level decision information according to the preset The decision rule determines the compression level of the user access request; the insertion module 43 is used to insert the compression level into the user access request; the sending module 44 i...

Abstract

The invention discloses a method, a device and a system for compressing content, relates to the technical field of communication, and solves the technical problems that in the prior art, the compression device has high pressure, and all data content can be only compressed according to a single standard. The method comprises the following steps: a service gateway looks up the corresponding compression grade decision information according to the received user access request, determines the compression grade of the user access request according to the compression grade decision information and the preset decision rule, inserts the compression grade in the user access request and transmits the user access request to a cache system entity; the cache system entity intercepts the user access request transmitted by the service gateway, and looks up whether the data content corresponding to the user access request is stored; if finding out the corresponding data content, the cache system entity resolves the compression grade in the user access request, compresses the found data content according to the compression grade, and returns the compressed data content to the service gateway. The method, the device and the system for compressing content are mainly used for compressing the content.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a content compression method, device and system. Background technique [0002] The rapid development of data services has led to a substantial increase in the data traffic carried by the mobile network, which in turn leads to a sudden increase in the transmission pressure of the mobile communication network. In order to alleviate the pressure on the bearer network, it is necessary to properly compress the content (including text, pictures, videos, etc.) transmitted by a specific user when using a specific data service. [0003] Currently existing compression technologies include content compression and protocol optimization. Among them, content compression is divided into three categories according to the compression objects: (1) Text compression: mainly to reduce redundant information (such as redundant symbols and notes), etc.; (2) Image compression: including c...
