Problems solved by technology

[0004] The access point of the telecommunication network number detection system is located between the TSS (Tandem Soft Switch) of the toll office. According to the principle of mobile calling, in the SIP / BICC call signaling between the toll offices, the called number is The temporarily assigned MSRN / TLDN number cannot directly identify the specific user from this number, and cannot realize the harmful fraudulent number detection function associated with the calling and called numbers

Embodiment Construction

[0019] Such as figure 1 As shown, the overall mobile call process is as follows:

[0020] (1) After the mobile user accesses the current VMSC of the end office through the power-on and location update process, the HLR records the current VMSC of the user. When the calling party calls the mobile user, use the mobile phone number MSISDN / MDN to initiate the call. From the calling end office VMSC or the calling gateway office GMSC, query the HLR for the called end office VMSC according to the MSISDN / MDN number. Among them, the G / W network operates through the SRI of the MAP protocol. C network, operated by LocReq of MAP.

[0021] (2) The HLR applies to the VMSC for a temporary dynamic roaming number according to the VMSC registered by the user. Among them, the G / W network applies for the MSRN number through the RPN operation of the MAP protocol. The C network applies for a TLDN number through the RoutReq operation of the MAP protocol.

[0022] (3) After the calling end offic...

Abstract

The invention discloses a method for acquiring a real called number in mobile network calling, and provides a solution scheme of C / D port parallel connection and Nc port serial connection. The methodcomprises the following steps: introducing a MAP protocol analytic processing mechanism, resolving a MSRN / TLDN number application procedure, and dynamically acquiring a mapping relation between a MSISDN / MDN number and a MSRN / TLDN number for the use of the calling processing. The method disclosed by the invention has the advantages that a C / D port traffic parallel connection and the Nc port serialconnection combined processing way is used for realizing the real-time dynamic acquisition of the MSRN / TLDN number and the MSISDN / MDN number; the processing can be performed according to the real called number MSISDN / MDN when the Nc port signaling is resolved from the function, the obvious operability and practical significance are provided; the C / D port traffic in parallel connection way is freefrom any influenced on the C / D port service from the affection influence, and the influence on the existing network is reduced to the lowest.

Description

technical field [0001] The invention relates to the field of telecommunication network security and real-time online detection of fraudulent numbers, in particular to a method for obtaining a real called number in a mobile network call. Background technique [0002] With the development of communication technology, mobile network communication has become the current mainstream. Compared with the traditional fixed network communication, the mobile network has the convenience of mobile roaming. At the same time, since the access point of the mobile user is not fixed, the mobile call flow needs to dynamically address the called party according to the user's access point. [0003] For this reason, the concept of temporary dynamic roaming number has been introduced in mobile communication. This number is called MSRN number in G / W network and TLDN number in C network. MSRN / TLDN is allocated and maintained in the VMSC of the end office, and each VMSC reserves a specific number s...
