Embodiment Construction

[0013] For the specific implementation of this program, please refer to figure 1 The schematic diagram shown. In the short message transmission path, a short message filtering computer is connected in series. As an example, the owner 13987654321 has asked the telecom operator to filter out all the short messages sent to him in advance. The short message filtering computer found that the phone number 13900000001 is in the Sending in groups, and one of the group sending short messages is sent to 13987654321, then the short message filtering computer will modify the received IP packet carrying the short message as follows: Change the recipient number of this short message to 90000000000 (assuming that this number is used to receive filtered short messages), and the source IP address and destination IP address of this IP packet remain unchanged, and the text of the short message also remains unchanged (IP and its upper layer protocol The checksum can be modified as required), aft...

Abstract

The method comprises: in the path of transmitting the short message, a short message filter is connected in series; for the short message not desired by user, the short message filter is replaced the receiving side number with other numbers and returns the short message to the transmission path in order to ensure the user not receive the short message so as to reach the aim of filtering out it; for other short message, a transparent forwarding is used. The short message filter can identifies if the number is from a group number's sending according to the frequency of short message with same contents sent from one number, and decides if the message is desired according to the preset white list and black list.

Description

technical field [0001] The invention relates to a short message filtering method, which is suitable for the short message communication network of the telecommunication operator. Background technique [0002] With the rapid development of mobile communication technology, the number of mobile terminals has reached hundreds of millions, and the traffic of short messages has also increased rapidly. Due to the proliferation of short messages, especially some criminals who use the convenience of short messages to spread some harmful information, a large number of mobile phone users are dissatisfied, but there is no effective way to stop useless, boring and harmful short messages The emergence of. Contents of the invention [0003] 1. Purpose of the invention: the purpose of the present invention is to provide a short message filtering method for the deficiencies in the prior art, so that telecom operators can help users effectively filter out short messages that they do not wa...
