Embodiment Construction

[0038] The inventors found that none of the existing bad packet detection schemes can effectively and efficiently detect whether a data service packet including a picture object and a video object is a bad packet.

[0039] The basic thinking of the present invention is: first respectively establish the sample sets corresponding to three types of bad objects (bad text objects, bad picture objects and bad video objects), the bad objects in the sample sets respectively correspond to a feature vector, and the elements in the feature vector The value is determined according to the discriminant rule corresponding to the element;

[0040] When detecting the received message, first extract the contained text object, picture object or video object from the received message; for each extracted object, determine the extracted object according to the discrimination rule corresponding to the category to which the object belongs , and then determine the probability that the extracted object...

Abstract

The invention discloses a bad message detection method and a bad message detection device, which are used for solving the problem that whether relevant messages of mobile service such as multimedia, mobile internet and the like are bad messages or not cannot be detected in the prior art. The method comprises the steps of: respectively building a set of at least two kinds of bad objects, wherein each object in the set respectively corresponds to a feature vector and the feature vector is determined according to a preset discrimination rule corresponding to the objects of a class; extracting objects from the obtained message; aiming at each extracted object, determining the feature vector of the object on the basis of the discrimination rule corresponding to each object class; determining the probability that the object is a bad object according to the feature vectors of the bad objects in the bad object set of the class of the object and the determined feature vector of the object; and determining the probability that the message is a bad message according to the determined probability that the object which is extracted from the message is the bad object.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for detecting bad messages, a method for establishing bad object sets and a device for detecting bad messages. Background technique [0002] With the rapid development of mobile communication technology, especially the 3G network and 3G mobile terminal technology that can support high-speed data services in recent years, MMS services and mobile Internet services have gradually become widely used after traditional voice services and short message services. mobile business. [0003] The MMS service enables messages sent between different users to contain not only text content, but also picture content. Mobile Internet services enable people to access the Internet anytime and anywhere, obtain the latest information, watch pictures, videos, etc. The common point between MMS and mobile Internet services is that the messages exchanged between different mobile co...
