Each CAP message collection device 1 is usingd without signaling point code working method serial connection or is connected across on the mobile switching centre/mobile network gateway exchange and the signaling link between Signaling System Number 7 net 3 as Service Switching Point, or to be connected in series or to be connected across on the signaling link between service control point and Signaling System Number 7 net 3 without signalling coding working method; Each CAP message collection device 1 respectively acquisition stream, through each CAP signaling message of place signaling link separately, and is transferred to each signaling message APU 2;
Every signaling message APU 2 is provided with a calling frequency in advance, it is the number of times that in the unit interval, prepaid user calls out, this unit interval can arrange, such as being arranged to 15 minutes, 30 minutes, 1 hour etc., thereby this calling frequency is various, such as 500 times/hour, 300 times/30 minutes, 180 times/15 minutes etc.; Every signaling message APU 2 receives each CAP signaling message, from these CAP signaling messages, sort out each initialization detect-message, and these initialization detect-message are decoded and obtained each calling number, add up the calling frequency of each calling number, using the calling number that surpasses described predefined calling frequency as black list user, and black list user is reported to centralized management system 4 in real time or periodically;
Centralized management system 4 pipes off the black list user of reception, and provides blacklist sync cap to harassing call control system, for entering follow-up interception, provides interception foundation, thereby reduces the complaint of user to harassing call.
Further, centralized management system 4 also connects respectively each CAP message collection device 1, thereby the running status of each CAP message collection device 1 and each signaling message APU 2 is carried out to real-time tracking and control, can manage concentratedly whole system.
Between each CAP message collection device 1 and each signaling message APU 2, by data network, be connected, between each signaling message APU 2, form mutually load sharing pattern, or adopt active-standby mode to carry out work; When certain CAP message collection device 1 and one or more signaling message APU 2 chain rupture, can automatically collected CAP signaling message be forwarded to and be connected in normal signaling message APU 2, guarantee that the CAP signaling message gathering is not lost.In Fig. 1, SS7 refers to Signaling System 7.
Refer to Fig. 2, the present invention's two the detection pre-payment harassing call user's based on the described system of one of the present invention method, comprises the following steps:
Step S1, each CAP message collection device 1 gathers the CAP signaling message of flowing through on the signaling link at place separately, and these CAP signaling messages are transferred to signaling message APU 2;
Step S2, each CAP signaling message of 2 pairs of receptions of signaling message APU sorts, and identifies every initialization detect-message in CAP signaling message;
Step S3,2 pairs of each initialization detect-message of signaling message APU (mainly refer to: CAMEL application protocol) decode, according to decoded result, sort out entrained calling number in every initialization detect-message according to protocol specification;
Step S4, signaling message APU 2 is arranged according to time order and function order each calling number obtaining in step S3 on time shaft, according to the window size arranging, the opposite direction that time point extended to the time arbitrarily on time shaft, determine the window time period, add up the number of times that same calling number falls into the window time period, using the calling number that surpasses predefined maximum times as black list user; Wherein, the window size of setting refers to the unit interval arranging; Predefined maximum times refers to predefined calling frequency;
Step S5, signaling message APU 2 by the black list user who obtains or in real time, or periodically reports centralized management system 4; Then, centralized management system 4 enters step S6, and CAP message collection device 1 and signaling message APU 2, from step S1, continue to detect;
Step S6, centralized management system 4 pipes off the black list user of reception, real-time update storage.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
