Realization method, device, sim server and terminal of virtual sim card

Abstract

The present invention provides a virtual SIM card implementation method, device, SIM server and terminal. The method includes: receiving a request message for applying for a virtual SIM sent by a terminal; allocating SIM information according to the request message, where the SIM information includes an international mobile subscriber identity code; performing network registration according to the SIM information; User parameters allocated by the network side device, the user parameters include a temporary mobile subscriber identity code and a key; the user parameters and the international mobile subscriber identity code are sent to the terminal. In the present invention, after the SIM information is allocated by the SIM server, the SIM server can directly perform network registration, obtain the temporary mobile user identification code and key allocated by the network, and then the terminal can directly use the temporary mobile user identification code and key for subsequent registration, A new authentication process can be avoided, thereby reducing the dependence on the data path in the virtual SIM card registration process, and improving the virtual SIM card registration success rate.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, a device, a SIM server and a terminal for implementing a virtual SIM card. Background technique [0002] In the traditional SIM usage scenario, operators and users need to rely on the physical SIM card for identity authentication, payment, business processing and other related activities. In a mobile roaming scenario, using a physical SIM card to make calls, surf the Internet or perform other services will incur higher roaming charges. In response to this situation, some manufacturers have proposed virtual SIM card solutions. By cooperating with local operators, virtual SIM cards are dynamically allocated to enable users to 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. In this solution, when the terminal performs network reg...

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
