Embodiment Construction

[0034] Usually, for such harassing calls as "the phone only rings once", it can be easily identified by judging the length of the ringing time. But the user may not be there when the mobile phone receives an incoming call, so when the user sees that his mobile phone has a missed call from a stranger, he cannot judge the length of the ringing time, and cannot confirm whether the incoming call is a harassing call or a call that has something to do. If the mobile phone can display the ringing time of the incoming call, it will help the user to make a correct judgment on whether the incoming call is such a nuisance call.

[0035] In the prior art, a caller display function can be realized, that is, the caller number and caller time can be displayed for the terminal. However, in the prior art, there is no solution capable of displaying the ringing time, so that when the terminal receives an incoming call but the user is not present, it cannot provide an effective reference for the ...

Abstract

The embodiment of the invention provides a method for identifying an illegal incoming call, which is used in a mobile terminal and is characterized by comprising the following steps: recording a first time as T1 when a calling party and a called party establish a communication channel; recording a second time as T2 when the called party has no response and the calling party cuts the communication channel; calculating the difference between the T1 and the T2, and obtaining a time interval delta t to be compared; comparing the time interval delta t to be compared with preset time interval value to produce a comparison value; and according to the comparison value, judging whether an incoming call of the calling party is the illegal incoming call. The method can effectively identify whether the incoming call is the illegal incoming call according to the ringing time of the incoming call, prevent a user from calling back and reduce the loss of the user through a mode of displaying a prompting message of a harassing call to the user or directly shielding incoming call number.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for identifying illegal incoming calls. Background technique [0002] At present, the development of mobile communication has become very popular, bringing great convenience to people's daily life. But at the same time, some malicious acts using the communication network are becoming more and more rampant, seriously destroying the harmony of the communication environment. [0003] For example, after "spam text messages" and "fraud phone calls", illegal calls that "only ring once" began to "attack" mobile phone users on a large scale. If you call back, you will pay several times or even dozens of times higher than the normal communication fee, which will bring great economic losses to the harassed person. Therefore, it is necessary to take necessary measures to minimize this adverse effect on the user. Inconvenience. [0004] However, there is...
