A method and a terminal device for keeping a subscriber identity module card in a standby state, including receiving an enabling request to enable dual standby of a first subscriber identity module (SIM) card and a second SIM card in the terminal device, wherein the first SIM card is software-implemented, and wherein the second SIM card is hardware-implemented, accessing a first network for the first SIM card by invoking a third-party interface of an operating system of the terminal and using a data file associated with the first SIM card, and implementing a dual standby of the first SIM card and the second SIM card.

Method and terminal for keeping subscriber identity module card in standby state

Implementation and communication methods, an apparatus and a system of a virtual subscriber identity module (VSIM) are provided. The implementation method includes: receiving a VSIM application request sent by a terminal, where the VSIM application request carries an identifier of a VSIM desired by the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, so that the terminal installs the VSIM according to the VSIM installation information. According to the present application, a problem where an existing mobile operator network does not support the VSIM is effectively solved, and an effective and convenient operation scheme is provided for an existing domestic or international roaming service.

Implementation and communication methods, apparatus and system of virtual subscriber identity module

The present invention provides implementation and communication methods, an apparatus and a system of a virtual subscriber identity module. The implementation method includes: receiving a VSIM application request sent by a terminal, where the VSIM application request carries an identifier of a VSIM desired by the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, so that the terminal installs the VSIM according to the VSIM installation information. The embodiments of the present invention effectively solve a problem where an existing mobile operator network does not support the VSIM, and provide an effective and convenient operation scheme for an existing domestic or international roaming service.

The present disclosure provides implementation and communication methods, an apparatus and a system of a virtual subscriber identity module. The implementation method includes: receiving a VSIM application request sent by a terminal, where the VSIM application request carries an identifier of a VSIM desired by the terminal; obtaining corresponding VSIM installation information according to the identifier of the desired VSIM; and sending the VSIM installation information to the terminal, so that the terminal installs the VSIM according to the VSIM installation information. The embodiments of the present disclosure effectively solve a problem where an existing mobile operator network does not support the VSIM, and provide an effective and convenient operation scheme for an existing domestic or international roaming service.

A method and a terminal device for keeping a subscriber identity module card in a standby state, where the method for keeping a subscriber identity module card in a standby state includes receiving, by a terminal device, an enabling request, where the enabling request is used for requesting simultaneous standby of a first subscriber identity module card and a second subscriber identity module card; invoking a third-party invocation interface provided by an operating system of the terminal device; performing interaction with a subscriber identity module card control module, so as to complete a network access process of the first subscriber identity module card on the basis of a data file of the first subscriber identity module card; and keeping the first subscriber identity module card and the second subscriber identity module card in a standby state at the same time according to the enabling request.

The present invention discloses a method for implementing a SIM card function on a terminal, a terminal and a UICC. The method includes: downloading information for implementing the SIM card function; writing the information for implementing the SIM card function into a reserved storage space of the terminal; and after the SIM card is activated, authenticating an access identity of a terminal user by using the information for implementing the SIM card function. In the present invention, the information for implementing the SIM card function is downloaded to the terminal, so as to implement the SIM card function by means of software.
