Description of drawings
Fig. 1 is the structural representation of terminal of the present invention;
Fig. 2 is the method flow diagram that terminal of the present invention is filtered suspicious call.
Embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, terminal proposed by the invention comprises three modules,
Call processing module: this module major function is the call function of processing terminal, also is used to calculate and write down the ring duration of missed call, and this ring duration is sent to the detection processing module of suspicious call.
The detection processing module of suspicious call: this module is used for detecting according to the ring duration suspicious call of missed call, and it is carried out filtration treatment.For the missed call that is present in the phone directory, this module can not detect and filtration treatment it.
This module comprises detection module, suspicious missed call processing module again, and detection module wherein is used to set normal call minimum ring time, and the ring duration is judged to be suspicious call less than the missed call of normal call minimum ring time; Suspicious missed call processing module is used for described suspicious call is not presented at the missed call tabulation of terminal, perhaps generates in order to the information to the user prompt suspicious call.
The user presents module: this module is used to show needs the information that presents to the user, and this module need be supported the information after suspicious call detects the processing module tissue treatment.
Be example with the WCDMA calling below, specify the flow process that suspicious call is handled of terminal of the present invention, as shown in Figure 2:
201, after called subscriber place MSC had received the setup requests of caller, the call processing module of called user terminal was handled this setup requests.Finally, called user terminal sends ALERTING (ring) message to described MSC, shows oneself ring, is waiting for called subscriber's off-hook.
202, the called subscriber as yet not before the off-hook, described called subscriber place MSC has promptly received the call release request that Calling Side is sent.Described immediately MSC has begun to call out the release flow process, and after terminal called was received DISCONNECT (call out and discharge) request, the call processing module of called user terminal was handled this call release request.
203, the call processing module of called user terminal calculates the ring duration.A kind of computational methods are that terminal is sent ALERTING message to receiving that time span between the DISCONNECT request is as ring duration T.This is the computational methods that the present invention recommends, and can also use on the user terminal actual chime playout length as ring time in addition.More than two kinds of computational methods generally have the regular hour gap, but error should be little.
204, after the call processing module of called user terminal calculates ring duration T, its other information with missed call are sent into suspicious call detect the processing module processing.
205, suspicious call detects ring duration that processing module judges missed call whether less than predefined normal call minimum ring time, if, judge that then this missed call is a suspicious call, present strategy according to suspicious missed call and organize generation need present to user's information; Otherwise, judge that this missed call is non-suspicious missed call, present strategy according to the normal missed call that pre-establishes and organize the information of presenting to the user that generates.General common strategy can for:
A) T does not list the missed call tabulation of terminal in less than the missed call of normal call minimum ring time.
B), all it is listed in and show its corresponding T value in the missed call tabulation and in each bar missed call no matter the length of T and whether less than normal call minimum ring time.
C) T lists the missed call tabulation of terminal in less than the missed call of normal call minimum ring time, but need to show length ring time, and have information (as using prompt text or using special color or the like) to be shown to the user to show that this missed call is too short ring time, be suspicious call.
D) it is also conceivable that with the phone directory stored on the terminal and combine, if the missed call number is present in the phone directory, then no matter ring time length, all do normal demonstration, for non-existent number in the phone directory again according to distinguishing ring time.
206, suspicious call detects processing module and the information that is generated is sent to the user presents module.
207, the user presents module and receives that suspicious call detects the processing that presents of the laggard line correlation of missed call relevant information that need that processing module sends present.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
