Problems solved by technology

For the black and white lists of spammers on the server side, the static black and white list technology has exposed many shortcomings: lack of flexibility; black and white lists are difficult to establish and maintain
The technical solution of updating the black and white lists based on user reports also has many shortcomings: for example, there is a risk that the call recipient may maliciously report the call originator, and there is also a lack of remedial mechanisms for normal users who are misjudged

Embodiment 1

[0025] Embodiment 1 of the present invention provides a call filtering device, which implements dynamic updating of black and white lists by quantifying reputation values ​​of abnormal call behavior patterns of calling parties.

[0026] image 3 It is a specific functional block diagram of the call filtering device in Embodiment 1 of the present invention, such as image 3 As shown, a call filtering device 10 according to Embodiment 1 of the present invention includes: a call detection unit 11 , a reputation value calculation unit 12 , a black and white list determination unit 13 , a call filter unit 14 , and an initial reputation value setting unit 15 . The functions of each unit and the working process of the filtering device 10 in the embodiment of the present invention will be described in detail below.

[0027] see image 3 , an initial reputation value setting unit 15, configured to set an initial reputation value for the calling party. Optionally, when a preset upper...

Embodiment 2

[0038] Embodiment 2 of the present invention detects the calling behavior pattern of the caller within the preset number of calls, and performs reputation value quantification and dynamic adjustment of the reputation value increase or decrease for its normal or abnormal call behavior (the higher the reputation value, the more the caller The more normal the call behavior of the caller, the lower the reputation value, indicating that the calling party is likely to be a spam call), and then match the current reputation value of the calling party with the reputation value threshold range of the black and white list to realize the dynamic update of the black and white list. In this way, the call filtering of spam calls is realized according to the information of the black and white lists.

Embodiment 3

[0074] Embodiment 3 of the present invention calculates the multi-conditional probability by detecting multiple abnormal calling behaviors that occur simultaneously within the preset number of calls of the calling party, and then calculates the reduced reputation value of the calling party according to the multi-conditional probability to generate the calling party The current reputation value is matched with the threshold range of the reputation value to realize the dynamic update of the black and white lists, and finally the call filtering is performed according to the information of the black and white lists.

Abstract

The embodiments of the present invention provide a call filtering method and device, which realizes call filtering through dynamic management of black and white lists. The device comprises: a call detection unit for detecting the call behavior pattern of the calling party; a reputation value calculation unit for generating the current reputation value of the calling party according to the call behavior pattern of the calling party; a black and white list determination unit for When the generated reputation value is greater than a threshold, the calling party is recorded in the whitelist; or when the generated reputation value is less than a threshold, the calling party is recorded in the blacklist; the call filtering unit is used for The call is filtered according to the blacklist or whitelist information determined by the black and white list determining unit. The device and method of the present invention can improve the detection efficiency and accuracy of spam calls, and at the same time can realize automatic update of black and white lists.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a call filtering method and device. Background technique [0002] With the rapid development of VoIP, the low-cost characteristics of VoIP calls have caused a flood of spam calls. Spam calls are defined as a large number of call requests that normal users do not want to receive or have nothing to do with the user. The purpose is to establish multimedia communication with the called user, and to advertise to the user through multimedia information such as text, audio or video. Activities such as sales promotion or fraud, in order to benefit spammers to obtain considerable commercial profits from it. [0003] In order to curb the pervasiveness and raging of spam calls on VoIP, a solution in the prior art is: a static black and white list technology is used to filter spam calls on both the mobile communication terminal and the communication server. For example, install junk...
