The network authentication center then compares the generated first verification information with the second verification information sent by the called terminal to determine whether they are the same. If the first verification information is the same as the second verification information, it means that the authentication information stored in the calling terminal is The key and authentication algorithm are the same as the authentication key and authentication algorithm corresponding to the calling number stored in the network authentication center. Therefore, it shows that the calling number used by the calling terminal when requesting to communicate with the called terminal is reliable. , is not a number forged by criminals using the network and VoIP technology. At this time, a verification result indicating that the calling number verification is legal is returned to the called terminal, so that the called terminal communicates with the calling terminal according to the verification result. If the first verification information is different from the second verification information, it means that the authentication key and authentication algorithm stored in the calling terminal are the same as the authentication key and authentication algorithm corresponding to the calling number stored in the network authentication center Not the same, therefore, it means that the calling number used by the calling terminal to request for communication and interaction with the called terminal is unreliable, and may be a number forged by criminals using the network and VoIP technology. At this time, the calling number is returned to the called terminal. An invalid verification result is verified, so that the called terminal refuses to communicate with the calling terminal according to the verification result.

In the mobile phone number verification method provided in this embodiment, when the called terminal receives the communication interaction request initiated by the calling terminal through the calling number, it first judges whether the calling number is credible, and if it is credible, further according to the first verification information and Whether the second verification information is the same to verify whether the calling number is legal, wherein, the first verification information is that the network authentication center conducts a random sequence code according to the authentication key and the authentication algorithm stored locally and corresponding to the calling number.
