Virtual SIM card implementation method and apparatus, SIM server and terminal

Abstract

The invention provides a virtual SIM card implementation method and apparatus, an SIM server and a terminal. The method comprises the following steps: receiving a virtual SIM application request message sent by the terminal; allocating SIM information according to the request message, wherein the SIM information comprises an international mobile subscriber identity; performing network registrationaccording to the SIM information; obtaining user parameters allocated by a network side device after the registration is successful, wherein the user parameters comprise a temporary mobile subscriberidentity and a key; and sending the user parameters and the international mobile subscriber identity to the terminal. By adoption of the virtual SIM card implementation method and apparatus providedby the invention, after the SIM server allocates the SIM information, the SIM server directly performs the network registration to obtain the temporary mobile subscriber identity and the key allocatedby the network, and the terminal directly uses the temporary mobile subscriber identity and the key to perform subsequent registration, so that a new authentication process can be avoided, thereby reducing the dependence on a data path in a virtual SIM card registration process and improving the virtual SIM card registration success rate.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for realizing a virtual SIM card, a SIM server and a terminal. Background technique [0002] In traditional SIM usage scenarios, operators and users need to rely on physical SIM cards for identity authentication, fee payment, and business handling. In the mobile roaming scenario, using a physical SIM card to make calls, surf the Internet, or perform other services will incur high roaming charges. In response to this situation, some manufacturers have proposed a virtual SIM card solution. By cooperating with local operators, they can dynamically allocate virtual SIM cards so that users can obtain local user services, thereby avoiding expensive roaming charges. [0003] The implementation of the existing virtual SIM card is usually a cloud SIM card solution. When the terminal registers with the network through the IMSI (International Mobile Subscriber Id...

Problems solved by technology

In this implementation method, an available data path is required for the interaction between the authentication request and the authentication result between the terminal and the SIM server during the registration process. For single-card or dual-card dual-standby mobile terminals, this data path can only rely on WIFI Network, when there is no WIFI available, cloud SIM authentication interaction cannot be performed
