What is the dynamic number?

The technical name of mobile phone dynamic code is mobile phone dynamic password. This is a one-time effective password security protection measure, which is widely used in the market.

The mobile phone dynamic password is a random password generated or received by using the mobile phone as the terminal. When the user logs into the application system, the generated or received password on the mobile phone is constantly changing, which greatly improves the security of user identity authentication or transaction, and is widely used in online banking, third-party payment, securities, telecommunications, e-government, enterprises and other fields.

for example, we pay online, which is basically the way we do it now.

if the applied dynamic number exceeds a certain period, the number will be invalid and cannot be used any more. Therefore, when the user dials again, the phone will prompt "The number you dialed has expired".

MSC-Server assigns a temporary number to its mobile phone users when they are called, which is used for the call connection. The number of digits is the same as that of the mobile phone number. Generally, each MGW uses a number sequence with the first 8 digits fixed, so that all MSRN of an MGW are 1.

it can also be considered as an inquiry number temporarily assigned to the mobile terminal, which is used to find the mobile terminal during the call. MSRN is assigned to every mobile terminal in a call, not only the roaming terminals between different MSCs, but also the roaming mobile terminals.

MSC set up and release the end-to-end connection, and handles the requirements of mobility and hand-over during the call, as well as billing and real-time prepaid account monitoring.
