Detailed ways

In order to solve the following problems in the prior art: downloading resources from a third-party server needs to occupy a certain bandwidth, and with the increase of intelligent terminals, more and more bandwidth will be occupied, which will cause the shortage of spectrum resources available to operators; the present invention A data sending method, device and data gateway are provided, and the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The first embodiment of the present invention provides a data sending method, the flow of the method is shown in Figure 1, including steps S102 to S108:

S102, when receiving the data from the third-party server, extract feature information from the data, wherein the data from the third-party server is data returned according to the request of the user equipment;

S104, judging whether there is a feature value whose matching degree with the feature information reaches a preset matching degree in the preset feature value database;

S106, if there is a feature value whose matching degree reaches a preset matching degree, send the original data corresponding to the feature value to the user equipment;

S108. In the case that there is no feature value whose matching degree reaches a preset matching degree, send the data from the third-party server to the user equipment.

The embodiment of the present invention extracts feature information from data from a third-party server, and matches the extracted feature information with feature values in a preset feature value database to determine whether there is a feature value with a matching degree reaching a preset matching degree , if there is, it means that the data gateway stores data that needs to be sent to the user device, and then directly extracts the original data corresponding to the feature value from the local and sends it to the user device, if not, then sends the data from the third-party server to the user device , the process data gateway performs a matching operation. Once the data required by the user equipment exists locally, it can be directly sent to the user equipment without occupying bandwidth and downloaded from the third-party server, which solves the following problems in the prior art: from the third-party server The upload and download resources need to occupy a certain amount of bandwidth. With the increase of smart terminals, more and more bandwidth will be occupied, which will cause the shortage of available spectrum resources for operators.

During the implementation process, the type of data can also be judged. If the user acquires text data or picture data, the bandwidth occupied by the download is small; if the user acquires audio data or video data, the bandwidth occupied by the download will be larger, therefore, it is also possible to first determine whether the data is audio data and/or video data; if the data is audio data and/or video data, extract feature information from the data; if the data is not audio data and/or video data, the data is sent to the user equipment. This process can optimize the processing process of the data gateway and reduce the processing load of the data gateway.

When extracting feature information from data, sample data may be collected from the data according to predetermined sample collection rules, and feature information may be extracted from the sample data. By collecting feature information in this way, sample data of feature information can be recorded, and when there are multiple feature values, it is convenient to accurately determine the data to be sent.

When there are multiple eigenvalues, match the sample data with the original data corresponding to each eigenvalue; among the obtained multiple matching degrees, send the original data corresponding to the eigenvalue with the highest matching degree to the user equipment. This process is a secondary matching process, which can increase the accuracy of the system. If the user's traffic is not considered, the original data with the top two or three matching degrees can also be sent to the user device. Of course, since this situation requires more traffic on the user device, the Requires prior permission from the user's device.

For the preset eigenvalue database, the construction process is as follows: each data stored locally is separated according to the predetermined separation rules to obtain the separated data; the eigenvalues of each separated data are extracted; the eigenvalues and The identity identification number corresponding to the feature value is hashed, and the processed result is saved to complete the construction of the preset feature value database.

After the data from the third-party server is sent to the user equipment, since the data from the third-party server has been downloaded, the data can be saved locally and added to the preset feature value database according to the data, so that Next time other user equipments want to acquire the same data, they can acquire it from the data gateway.
