Authentication and communication method of mobile terminal without card, server and mobile terminal without card

Abstract

The invention discloses a card-free mobile terminal authentication and communication method. The physical object of the traditional SIM (Subscriber Identity Module) card is integrated in an integrated circuit of a card-free mobile terminal, and the card-free mobile terminal stores the subscriber identity information of at least one telephone number in a readable manner. The authentication and communication method comprises the following steps of: authenticating the authentication information sent by the card-free mobile terminal actively and corresponding to the telephone number; and communicating and interacting with the telephone number corresponding to the authentication information after the authentication is passed. The invention also provides a server and a card-free mobile terminal accordingly. Therefore, the card-free mobile terminal can realize communication without SIM card, and the subscriber identity information of more than one telephone number can be stored to realize one machine with more numbers. The subscriber can also modify the authentication information corresponding to the telephone number, so that the operation of the subscriber is more convenient.

Description

technical field [0001] The invention relates to the communication field, in particular to an authentication and communication method of a cardless mobile terminal, a server and a cardless mobile terminal. Background technique [0002] Existing mobile terminals all include a SIM (Subscriber Identity Module, Subscriber Identity Card). The SIM card includes subscriber identity information of the mobile terminal, encrypted information and other user identification information. The server can identify the identity of the mobile terminal through the SIM card. The physical body of the SIM card usually consists of a central processing unit CPU (Central Processing Unit, central processing unit), working memory RAM (Random Access Memory, random access memory), program memory ROM (Read-Only Memory, read-only memory), data The memory EEPRoM (Electrically Erasable Programmable Read-Only Memory, Electrically Erasable Programmable Read-Only Memory) and the serial communication unit are com...

AI Technical Summary

Problems solved by technology

If a mobile terminal wants to realize simultaneous networking standby of multiple SIM cards, it is necessary to design multiple antennas, multiple communication modules and multiple SIM card holders on the circuit board of the mobile terminal, which not only makes the structural design of the mobile terminal quite complicated , and increases the form factor and cost of the mobile terminal

[0004] In addition, when the existing mobile terminal needs to change the phone number, the corresponding SIM card must be replaced, which not only increases the equipment cost of number replacement, but also brings inconvenience to the user's operation of changing numbers.

[0005] In summary, the existing mobile terminal technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
