【摘要】：随着手机用户数量及短信业务的高速增长,尤其是网络端可以向手机发送短信之后,垃圾短信泛滥已成为困扰通信运营商和手机用户的一个重大问题。垃圾短信主要有欺诈信息、假中奖信息、广告信息、色情信息等几种。垃圾短信已经影响到手机用户的心情、生活和工作;对通信运营商,垃圾短信也严重影响到其服务质量的提高;欺诈类、非法广告等短信甚至已经违反法律法规。因此,迫切需要建立一个高效可靠的垃圾短信判定系统。本文主要进行网络端垃圾短信判定系统的设计和实现。首先研究垃圾短信的基本特征、传统的垃圾短信判定方法、网络端垃圾短信的特点;其次,根据网络端垃圾短信发送间隔时间短、量非常大、关键词可能用拼音或同音字代替或用符号进行分割等的特点,结合传统的过滤方法中的关键词过滤,采用字符过滤、汉字转拼音、字符串匹配、关键词加权求和、根据长度进行调整等技术,设计一个基于界面事件驱动的相对精确的高效垃圾短信判定系统;最后用Visual Studio 2008和SQL SERVER 2005实现该系统,并且进行调试和测试。该判定系统是供通信运营商使用的,应结合包含接收者号码、接收者的黑白名单、接收号码数量等对发送号码进行过滤等号码相关信息的客户端一起使用。本文最终实现了对运营商信息中心接收到的短信,统一滤去无效字符,并将有效字符转为拼音,进行关键词匹配并计算权值和,然后根据权值之和与短信初始长度计算每24小时内允许发送的次数。
[Abstract]:With the number of mobile phone users and the rapid growth of SMS business, especially after the network can send short messages to mobile phones, spam messaging has become a major problem for communication operators and mobile phone users. Spam messages are mainly fraud information, fake winning information, advertising information, pornographic information and so on. Spam messages have affected the mood, life and work of mobile phone users; for communication operators, spam messages have also seriously affected the improvement of their service quality; fraud, illegal advertising and other text messages have even violated laws and regulations. Therefore, there is an urgent need to establish an efficient and reliable spam SMS decision system. This paper mainly carries on the design and the realization of the network side spam short message judgment system. First of all, the basic characteristics of spam SMS, the traditional method of judging spam SMS, the characteristics of spam SMS on the network are studied. Secondly, according to the short interval time of sending spam SMS on the network, the quantity is very large. The key words may be replaced by pinyin or homonym or segmented by symbols, combined with the traditional filtering methods, such as keyword filtering, character filtering, Chinese character conversion to pinyin, string matching, keyword weighted summation, etc. According to the technology of length adjustment, a relatively accurate and efficient spam short message decision system based on interface event driven is designed. Finally, the system is implemented with Visual Studio 2008 and SQL SERVER 2005, and the system is debugged and tested. The decision system is for the use of communication operators, should be used together with the receiver number, the black and white list of recipients, the number of receiving numbers to filter the number of sending numbers and other information related to the use of the client. Finally, the text message received by the operator information center is realized, the invalid character is uniformly filtered out, the valid character is changed into pinyin, the key words are matched and the weight value and, Then the allowed number of times per 24 hours is calculated based on the sum of weights and the initial length of the message.
