Abstract

Claims (31)

1. A method for establishing communication connections, comprising:

in response to a failure of a subscriber identity module (SIM) card, acquiring first key identifier (KI) card information, wherein in the case that locally stored roaming KI card information and non-roaming KI card information are both available, the first KI card information is the non-roaming KI card information, and in the case that the locally stored roaming KI card information is available whereas the non-roaming KI card information is not available, the first KI card information is the roaming KI card information;

establishing a first communication connection to a cloud SIM card management platform based on the first KI card information;

acquiring cloud SIM card information from the cloud SIM card management platform over the first communication connection; and

establishing a second communication connection based on the cloud SIM card information.

2. The method according to claim 1 , wherein in the case that the first KI card information is the roaming KI card information, the method further comprises:

acquiring second KI card information from the cloud SIM card management platform over the first communication connection, wherein the second KI card information is the non-roaming KI card information;

disconnecting the first communication connection; and

establishing the first communication connection based on the second KI card information.

3. The method according to claim 1 , wherein the roaming KI card information and the non-roaming KI card information being both available comprises:

the roaming KI card information and the non-roaming KI card information being both applicable to establishing the first communication connection.

4. The method according to claim 1 , wherein the roaming KI card information being available whereas the non-roaming KI card information being not available comprises:

the roaming KI card information being applicable to establishing the first communication connection whereas the non-roaming KI card information being not applicable to establishing the first communication connection.

5. The method according to claim 1 , wherein the first KI card information is virtual KI card information.

6. An apparatus for establishing communication connections, comprising: a processing unit and a communication unit; wherein

the processing unit is configured to:

in response to a failure of a subscriber identity module (SIM) card, acquiring first key identifier (KI) card information, wherein in the case that locally stored roaming KI card information and non-roaming KI card information are both available, the first KI card information is the non-roaming KI card information, and in the case that the locally stored roaming KI card information is available whereas the non-roaming KI card information is not available, the first KI card information is the roaming KI card information;

the processing unit is further configured to control the communication unit to:

establish a first communication connection to a cloud SIM card management platform based on the first KI card information;

acquire cloud SIM card information from the cloud SIM card management platform over the first communication connection; and

establish a second communication connection based on the cloud SIM card information.

7. The apparatus according to claim 6 , wherein the processing unit is further configured to control the communication unit to:

acquire second KI card information from the cloud SIM card management platform over the first communication connection, wherein the second KI card information is the non-roaming KI card information;

disconnect the first communication connection; and

establish the first communication connection based on the second KI card information.

8. The apparatus according to claim 6 , wherein the roaming KI card information and the non-roaming KI card information being both available comprises:

the roaming KI card information and the non-roaming KI card information being both applicable to establishing the first communication connection.

9. The apparatus according to claim 6 , wherein the roaming KI card information being available whereas the non-roaming KI card information being not available comprises:

the roaming KI card information being applicable to establishing the first communication connection whereas the non-roaming KI card information being not applicable to establishing the first communication connection.

10. The apparatus according to claim 6 , wherein the first KI card information is virtual KI card information.

11. A non-transitory computer-readable storage medium, storing one or more computer programs; wherein the one or more computer programs, when loaded and run by a processor, cause the processor to perform one or more of following: in response to a failure of a subscriber identity module (SIM) card, acquiring first key identifier (KI) card information, wherein in the case that locally stored roaming KI card information and non-roaming KI card information are both available, the first KI card information is the non-roaming KI card information, and in the case that the locally stored roaming KI card information is available whereas the non-roaming KI card information is not available, the first KI card information is the roaming KI card information; establishing a first communication connection to a cloud SIM card management platform based on the first KI card information; acquiring cloud SIM card information from the cloud SIM card management platform over the first communication connection; and establishing a second communication connection based on the cloud SIM card information.
