Embodiment Construction

[0032] The embodiment of this application provides a mobile phone number acquisition method, for example, the acquisition method can be applied to figure 1 As shown in the system architecture, the system architecture 100 includes a terminal 101, a mobile communication base station 102, a gateway device 103, a PS online billing system 104, a mobile phone number acquisition server 105, a national mobile phone number acquisition system 106, a firewall 107, and an Internet application server 108 Wait.

[0033] Multiple application programs run on the terminal 101, and each application program has its corresponding application program ID. The terminal 101 establishes a mobile Internet connection with the mobile communication base station 102 .

[0034] Gateway device 103 may include 2 / 3G gateway GSN (Gateway GPRS Support Node, GGSN), or 4G PDN gateway (PDN GateWay, P-GW) or 5G is responsible for the session management function (Session Management Function, SMF) of the control plan...

Abstract

The embodiment of the present application discloses a method and device for obtaining a mobile phone number, which relates to the field of communication technology, and solves the problem that current application programs or application servers cannot guarantee network security and user information security when obtaining a user's mobile phone number. The specific scheme is: receiving the ID of the application program and the first random number sent by the terminal; sending the second random number to the terminal according to the ID of the application program; receiving the first hash value sent by the terminal; according to the ID of the application program, the first random number The number and the second random number use a hash algorithm to generate a second hash value; if the first hash value and the second hash value are the same, the first server sends the first hash value or the second hash value, and the user private network The IP address and the user's mobile phone number are sent to the national mobile phone number acquisition system, so that the application server queries the national mobile phone number acquisition system according to the third hash value, and obtains the user's mobile phone number.

Description

technical field [0001] The embodiment of the present application relates to the field of communication technologies, and in particular to a method and device for obtaining a mobile phone number. Background technique [0002] At present, the number of mobile phone users and mobile Internet users in China is huge, and the number of public network IPv4 addresses owned by Chinese telecom operators is far from meeting the demand. Therefore, in actual networking, private network IPv4 addresses are allocated to users, and different provinces Or there is overlap and multiplexing of private network IPV4 addresses in prefectures and cities. When a mobile phone user accesses the mobile Internet, the packet gateway of the mobile communication network (for example, GGSN of the 3G network, P-GW of the 4G network, and SMF of the 5G network) will Private network protocol (Internet Protocol, IP) addresses are mapped to public network IP addresses through technologies such as network address ...
