Method and apparatus for authenticating a virtual subscriber identity module

An apparatus for authenticating a virtual subscriber identity module (VSIM), comprising:

• a processor, configured to establish a first connection with a mobile communication network according to a removable subscriber identity module (RSIM) in a terminal;
• acquire, via the first connection, VSIM information sent by a VSIM server, the VSIM information comprising a subscriber identification code of the VSIM;
• disable the first connection;
• initiate a registration request to a network side according to the VSIM information;
• acquire an authentication request for authentication for the VSIM, the authentication request carrying an authentication parameter to request for authentication for the VSIM;
• and establish a second connection with the mobile communication network according to the RSIM;
• and
• a transmitter, configured to send an uplink synchronous frame of the VSIM via the second connection;
• and send the authentication parameter to the VSIM server, such that the VSIM server determines an authentication response parameter according to the authentication parameter;
• wherein the processor is further configured to acquire the authentication response parameter sent by the VSIM server;
• and perform authentication according to the authentication response parameter.

An apparatus, comprising a processor coupled with a non-transitory storage medium storing executable instructions;

• wherein the executable instructions, when executed by the processor, cause the processor to:
• establish a first connection with a mobile communication network according to a removable subscriber identity module (RSIM) in a terminal;
• acquire VSIM information sent by a VSIM server via the first connection, the VSIM information comprising a subscriber identification number of the VSIM;
• disable the first connection;
• initiate a registration request to a network side according to the VSIM information;
• acquire an authentication request for authentication for the VSIM;
• establish a second connection with the mobile communication network according to the RSIM;
• send an uplink synchronous frame of the VSIM via the second connection;
• send an authentication parameter in the authentication request to the VSIM server, such that the VSIM server determines an authentication response parameter according to the authentication parameter;
• acquire the authentication response parameter sent by the VSIM server;
• and
• perform authentication according to the authentication response parameter.
