In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.

Fig. 1 is a flow chart illustrating a speech verification method according to an embodiment of the present invention. The method is executed by a voice verification platform and comprises the following steps:

in step 110, the originating MSC (Mobile Switching Center) identity of the calling terminal is obtained. When the calling terminal accesses a client platform, such as an SP (Service Provider) platform, the client platform issues a verification number to the calling terminal and triggers a call to a voice verification platform, and the verification number signs a verification Service and activates an access number forwarded to the voice verification platform unconditionally. The voice verification platform obtains the originating MSC identification in the calling flow of the calling terminal.

In step 120, a serving MSC identifier when the calling terminal dials the authentication number, which is sent from an HLR (home location register) of the calling terminal, is received. After receiving the verification number issued by the customer platform, the calling terminal dials the verification number, and the voice verification platform sends a SEARCH message to the HLR of the calling terminal, and the HLR of the calling terminal returns the service MSC identifier of the calling terminal to the voice verification platform. The step is that the voice verification platform obtains the service MSC identification in the mobile management flow of the calling terminal.

In step 130, if the originating MSC identification is consistent with the serving MSC identification, the calling terminal is determined to be a legitimate terminal.

In the embodiment, the originating MSC identification of the calling terminal in the call flow is compared with the service MSC identification of the calling terminal in the mobile management flow, so that the double-flow detection is realized, and the efficiency of the truth checking terminal can be improved.

Fig. 2 is a flow chart illustrating a speech verification method according to another embodiment of the present invention. The method comprises the following steps:

at step 210, the voice verification platform assigns a plurality of C-net verification numbers to the customer platform. And the C network authentication number signs a voice authentication service, and activates an access number forwarded to a voice authentication platform unconditionally.

In step 220, when the calling terminal accesses the client platform, the client platform optionally issues a C-network authentication number to the calling terminal and triggers the call to the voice authentication platform.

In step 230, the voice authentication platform obtains the originating MSC identification of the calling terminal from the WIN signaling message. Wherein, the GT (number for identifying each switch) of the calling terminal can be obtained by SCCP (Skinny Call Control Protocol) layer, the SCCP layer belongs to the transmission layer, the MAP layer belongs to the application layer, and the WIN message of MAP is carried on the SCCP layer. The GT of the calling terminal represents the equipment sending the message in the SCCP layer, the MSC mark represents the equipment sending the message in the MAP layer, each MSC has GT and MSC marks, and both are only corresponding to the same MSC.

The voice authentication platform sends a SEARCH message to the HLR of the calling terminal in step 240.

In step 250, the HLR of the calling terminal returns the serving MSC id when the calling terminal dials the C-ip number.

In step 260, the voice verification platform determines whether the originating MSC identifier is consistent with the serving MSC identifier, if so, step 270 is executed, otherwise, step 290 is executed.

In step 270, the voice verification platform sends a verification record including the number of the calling terminal, the C-net verification number and the verification result to the client platform.

In step 280, the customer platform compares the number of the calling terminal and the C-network verification number sent by the voice verification platform with the number of the calling terminal and the C-network verification number stored in the customer platform, and if the numbers are consistent and the verification result is true, the customer platform confirms that the calling terminal is credible.

In step 290, the voice verification platform interrupts the call of the calling terminal and performs call interception.

In the embodiment, the dual-flow test is realized by comparing the originating MSC identifier of the calling terminal in the call flow with the service MSC identifier of the calling terminal in the mobile management flow, so that the efficiency and the accuracy of the true-checking terminal are improved, the false calling terminal can be intercepted in real time, and the full-network true-checking and false-distinguishing capability is formed. As can be seen from the experimental data in Table 1, compared with the signaling monitoring true detection method, the method has the advantages that the true and false discrimination rate is over 99 percent, the response time is short, and the true detection real-time rate is within 2 s.

Authenticity recognition rate	80％	99％
			Real time rate of truth examination	1-2 minutes	1-2s

TABLE 1

Fig. 3 is a flowchart illustrating a voice verification method according to another embodiment of the present invention. The specific Network flow diagram is shown in fig. 4, where 410 is a user to be verified, 420 is an MSC, 430 is a GMSC (Gateway Mobile Switching Center), 440 is an HLR, 450 is a voice verification platform, and 460 is a PLMN (Public Land Mobile Network).

Suppose that the customer platform provides a telephone number 189 x 0195 and requests the terminal of the calling number 189 x 2599 to dial 189 x 0195 for calling verification.

In step 310, when the terminal of the calling number 189 × 2599 dials 189 × 0195, the switch where the terminal of 189 × 2599 is sends a location request (LOCREQ) message to the HLR where 189 × 0195 belongs to perform MAP addressing to obtain the roaming number for connection.

In step 320, 189 × 0195 belongs to the HLR, and configures an intelligent network service trigger for 189 × 0195 in advance, and the HLR returns a logreq response to issue a trigger of 38 (Initial _ Termination), 39 (Called _ Routing _ Address _ Available), and 34 (Location) to indicate that the call is an intelligent network call.

In step 330, the calling switch (O-MSC) first sends an analysis request (ANLYZD) message based on number 38 trigger, triggering the intelligent network flow to the voice verification platform. This message carries the calling number 189 x 2599, 189 x 0195 and its MSC ID (identification).

In step 340, the voice authentication platform marks the calling number 189 x 2599, 189 x 0195, triggers the originating MSC ID of the service, and returns an anlyzd response indicating that the call is continuing.

In step 350, the originating switch (O-MSC) first sends a LOCREQ message to 189 x 0195 home HLR according to the trigger No. 34.

At step 360, the HLR finds 189 x 0195 signed unconditional forwarding with a forwarding number 02150 x 79. The HLR returns a logreq response, issues triggers No. 37 (Calling _ Routing _ Address _ Available), No. 40 (O _ Answer), and No. 41 (O _ Disconnect), and indicates that unconditional forwarding occurs for the call, and the forwarding number is 02150 × 79.

In step 370, the voice authentication platform sends a SERACH message to the 18918532599 home HLR asking for 189 x 0195 the serving MSC ID where the current registration is.

In step 380, the HLR transmits 18918532599 the cached serving MSC ID where the current registration is located to the verification platform via the search response, and the voice verification platform records the MSC ID.

In step 390, the voice verification platform compares the originating MSC ID and the serving MSC ID recorded twice, and if the two are identical, the calling number of the call is considered to be credible and is a real calling number; if the two are not consistent, the calling number of the call is considered to be false, and the call is called out through the number changing software.

In step 3100, the originating switch (O-MSC) first sends an ANLYZD message to the authentication platform based on number 37 triggers the intelligent network flow, which carries the originating number 189 x 2599 and the forward to connect number 02150 x 79.

In step 3110, if the calling number is determined to be false, the voice verification platform may intercept the call and return an anlyzd response to interrupt the call, and if the calling number is determined to be true, the voice verification platform puts the call through and returns an anlyzd response to continue the call.

In step 3120, the calling switch routes the call from the calling number 189 x 2599, the called connection number 02150 x 79, and the original called number 189 x 0195 to the client platform.

In step 3130, the client platform receives the call, extracts the calling number 189 × 2599 and the original called number 189 × 0195, and by comparison, it is known that 189 × 0195 is used for calling verification when the terminal originally sent to 189 × 2599, thereby verifying that the calling number 189 × 2599 is authentic and the terminal is authentic.

In this embodiment, the C network number is triggered to the voice verification platform as the call initiated by the calling party, the platform acquires the ID of the originating MSC of the calling terminal carried in the call flow according to the WIN signaling message, and based on the ID of the originating MSC, it can know which switch the call enters the C network. Meanwhile, the voice verification platform sends a SEARCH message to the HLR to acquire the ID of the service MSC registered by the calling terminal when the calling terminal dials the call. If the service MSC ID where the terminal registration is located is consistent with the MSC ID of the calling originating call, the calling number of the call is judged to be true, otherwise, the call is false, and the voice verification platform can also intercept the false calling in real time. In addition, the voice verification platform sends verification records (C network verification number, calling terminal number and verification result) to the client platform in real time, the client platform extracts the calling number and the original called number from the calling signaling, and compares the verification records with self-caching records and the verification records sent by the voice verification platform, if the three are consistent and the verification result is true, the calling terminal is credible; otherwise, the calling terminal is not trusted. The scheme in the embodiment can well meet the innovative requirements of verification code services provided by users in the e-commerce and internet industries.

In another embodiment of the invention, the invention can also verify whether the international call is a false call. For example, a domestic mobile subscriber roams abroad, the subscriber terminal is used as a calling terminal to dial another domestic mobile subscriber, a call enters a domestic network from an international office, and a TMSC (transit mobile switching center) at the location of the international office triggers a voice verification platform. From a routing perspective, the user roams out and the originating MSC is some two specific pairs of MSCs. From the location update procedure, the user roams abroad, and the serving MSC should be the foreign MSC pair. Corresponding to the C-G roaming of the chinese telecommunications, the serving MSC is an international GC gateway. The international GC gateway is responsible for converting GSM MAP messages into CDMA MAP messages so as to realize that telecommunication CDMA users use the dual-mode terminal dual-mode card to roam in an overseas GSM network.

If a telephone with a calling number 189 x 2599 calls a called number from the international office into the network, the serving MSC is a domestic MSC, say in south beige. The terminal is in China, but the calling number with the same name is beaten to the domestic network from abroad, which shows that the number-changing software is beaten by counterfeiting.
