Embodiment

The present invention is further illustrated below in conjunction with the drawings and specific embodiments:

Analyzing the characteristics of above-mentioned fraud phone can find: when undesirable person's phone group dials, be call release after terminal called ring just.This is to dial the efficient cry in order to improve on the one hand, also is on the one hand to prevent that ring time is long and answered by the user, causes the undesirable person to lose telephone expenses.This shows, the weak point of establishing a capital comparison ring time one of this type of fraud phone, and common normal telephone generally is impossible such.Thereby the present invention judges according to length ring time of Inbound Calls whether Inbound Calls is the fraud phone, and then advise called subscriber.

System for prompting proposed by the invention comprises detection processing module, the suspicious call notification module of call processing module, suspicious call.

Above-mentioned call processing module is positioned at core network switches, is used to calculate and write down the ring duration of missed call; The detection processing module of suspicious call is positioned at core network switches, be used to set normal call minimum ring time, the ring duration is judged to be suspicious call less than the missed call of normal call minimum ring time, and the telephone number and the ring duration of this suspicious call sent to the suspicious call notification module; The suspicious call notification module is positioned at short message service center, is used for reminding to called user terminal by short message or multimedia message that described missed call is a suspicious call, comprises the telephone number and the ring duration of suspicious call in the notification message.

The detailed process that said system realizes the suspicious call prompting function is as shown in Figure 1:

101, normal call of definition minimum ring time on the mobile communication core network switches.

102, behind the dialed terminal bell, calculate and write down the ring duration of missed call, after calling out release, core network switches discharges flow processing by normal call.

103, core network switches judge called terminal ringing to time that caller discharges whether less than described normal call minimum ring time, if, then described called subscriber is notified, can adopt short message, multimedia message, means such as delivery email are notified, carry rear subscriber number and called terminal ringing and initiate the time span of release to caller, be used to remind the user that this missed call is very short ring time, may call out, judge follow-up how the processing voluntarily by the user for fraud; If not, then do not notify to the called subscriber.
