Time sharing subscriber identity modules

1. A method comprising:

detecting, during a first call associated with a first subscriber identity module included in a user equipment, a page representative of a second call associated with a second subscriber identity module;

receiving, during the first call associated with the first subscriber identity module included in the user equipment, an indication representative of the second call being detected for the second subscriber identity module; and

initiating, based on at least the received indication at the user equipment, the second call by at least switching a subscriber identity module being used by the user equipment from the first subscriber identity module to the second subscriber identity module.

2. The method of claim 1 , wherein the detecting further comprises:

switching, at the user equipment, reception from a traffic channel including the first call to a paging channel including the page to enable the detecting, wherein the switching is implemented programmatically under the control of the user equipment.

3. The method of claim 1 , wherein the paging channel comprises a physical downlink shared channel including a paging control channel, and the traffic channel comprises a physical downlink shared channel.

4. The method of claim 1 further comprising:

generating the indication as an audio indication configured to be played during the first call associated with the first subscriber identity module included in the user equipment.

5. The method of claim 1 further comprising:

generating the indication as a visual indication configured to be presented during the first call associated with the first subscriber identity module included in the user equipment.

6. The method of claim 1 further comprising:

ceasing the first call, when the second call is initiated.

7. The method of claim 1 , wherein the detecting further comprises:

detecting a second international mobile subscriber identity associated with the second call to the second subscriber identity module included in the user equipment.

8. The method of claim 1 further comprising:

establishing, based on the detected second international mobile subscriber identity, the second call.

9. The method of claim 1 , wherein the detecting further comprises:

pausing the first call to detect the page for the second subscriber identity module.

10. An apparatus comprising:

at least one processor; and

at least one memory including computer program code the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

detect, during a first call associated with a first subscriber identity module included in the apparatus, a page representative of a second call associated with a second subscriber identity module;

receive, during the first call associated with the first subscriber identity module included in the apparatus, an indication representative of the second call being detected for the second subscriber identity module; and

initiate, based on at least the received indication at the apparatus, the second call by at least switching a subscriber identity module being used by the apparatus from the first subscriber identity module to the second subscriber identity module.

11. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

switch, at the apparatus, reception from a traffic channel including the first call to a paging channel including the page to enable the detecting, wherein the switching is implemented programmatically under the control of the apparatus.

12. The apparatus of claim 10 , wherein the paging channel comprises a physical downlink shared channel including a paging control channel, and the traffic channel comprises a physical downlink shared channel.

13. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

generate the indication as an audio indication configured to be played during the first call associated with the first subscriber identity module included in the apparatus.

14. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

generate the indication as a visual indication configured to be presented during the first call associated with the first subscriber identity module included in the apparatus.

15. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

cease the first call, when the second call is initiated.

16. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

detect a second international mobile subscriber identity associated with the second call to the second subscriber identity module included in the apparatus.

17. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

establish, based on the detected second international mobile subscriber identity, the second call.

18. The apparatus of claim 10 , wherein the apparatus is further configured to at least:

pause the first call to detect the page for the second subscriber identity module.

19. A non-transitory computer-readable medium including code which when executed by at least one processor provides operations comprising:

detecting, during a first call associated with a first subscriber identity module included in a user equipment, a page representative of a second call associated with a second subscriber identity module;

receiving, during the first call associated with the first subscriber identity module included in the user equipment, an indication representative of the second call being detected for the second subscriber identity module; and

initiating, based on at least the received indication at the user equipment, the second call by at least switching a subscriber identity module being used by the user equipment from the first subscriber identity module to the second subscriber identity module.
