Abstract

A method for optimizing remote authentication of a virtual subscriber identity module (VSIM) for a multi-subscriber identity module (SIM) multi-standby (MSMS) mobile communication device includes: receiving a VSIM authentication request from a VSIM network; determining whether a previous packet switched (PS) connection between the VSIM and the VSIM network is available; in response to determining that the previous PS connection between the VSIM and the VSIM network is available, performing VSIM authentication using the previous PS connection between the VSIM and the VSIM network.

6. The method of claim 1, further comprising:

in response to determining that the previous PS connection between the VSIM and the VSIM network is not available, establishing a new PS connection between the VSIM and the VSIM network.

7. The method of claim 6, further comprising:

sending the VSIM authentication request to a VSIM server via the new PS connection between the VSIM and the VSIM network.

receive a VSIM authentication request from a VSIM network;

determine whether a previous packet switched (PS) connection between the VSIM and the VSIM network is available;

in response to determining that the previous PS connection between the VSIM and the VSIM network is available, perform VSIM authentication using the previous PS connection between the VSIM and the VSIM network.

10. The MSMS mobile communication device of claim 9, wherein the control unit is further configured to, when performing the VSIM authentication using the previous connection, control the communication unit to send the VSIM authentication request to a VSIM server via the previous PS connection between the VSIM and the VSIM network.

11. The MSMS mobile communication device of claim 10, wherein the control unit is further configured to, when performing VSIM authentication using the previous PS connection, receive a VSIM authentication response from the VSIM server via the previous PS connection between the VSIM and the VSIM network.

13. The MSMS mobile communication device of claim 9, wherein the control unit is further configured to, when determining whether a previous packet switched (PS) connection between the VSIM and the VSIM network is available, control the communication unit to attempt to perform a handshake with a VSIM server via the previous PS connection between the VSIM and the VSIM network.

14. The MSMS mobile communication device of claim 9, wherein:

in response to determining that the previous PS connection between the VSIM and the VSIM network is not available, the control unit is further configured to control the communication unit to establish a new PS connection between the VSIM and the VSIM network.

15. The MSMS mobile communication device of claim 14, wherein the control unit is further configured to send the VSIM authentication request to a VSIM server via the new PS connection between the VSIM and the VSIM network.

16. The MSMS mobile communication device of claim 15, wherein the control unit is further configured to receive a VSIM authentication response from the VSIM server via the new PS connection between the VSIM and the VSIM network.
