Abstract

The invention relates to the field of wireless communication and discloses a wireless terminal and a registration and authentication method thereof, which can ensure multiple telephone numbers in the same SIM (Subscriber Identity Module) or USIM (Universal User Identity Module) card stand by at the same time. In the invention, the wireless terminal comprises one SIM or USIM card which consists of at least two sub-cards, and each sub-card corresponds to one telephone number and comprises an IMSI (International Mobile Subscriber Identity) and a secret key. The method comprises the following steps of: acquiring the IMSI in the current sub-card; initiating network registration by using the acquired IMSI; when an authentication request from the network is received, carrying out authentication treatment by using the secret key in the current sub-card, and sending an authentication result to the network; and after the current sub-card authentication is successful, switching the other sub-card in the SIM or USIM card to be the current sub-card, and repeating the steps.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the registration and authentication technology of a wireless terminal with one card and multiple numbers. Background technique [0002] With the development of mobile communication technology, mobile phones have become one of people's daily necessities.
