Abstract

Various embodiments disclosed that describe systems to facilitate paging an idle subscriber identity module using a connected subscriber identity module operating in a single radio configuration. According to some embodiments, a system can comprise receiving a paging request that is designated for a first device of a communication device, wherein the communication device comprises the first device and a second device; determining whether the second device is in an active state; and in response to the determining that the second device is in the active state, transmitting a message to second device indicating that the paging message was received for the first device.

First claim

What is claimed is:

1. A method, comprising:
determining, by network equipment comprising a processor resulting in a first determination, whether a second subscriber identity module is in an active state with respect to a user equipment comprising a first subscriber identity module and the second subscriber identity module, wherein the first subscriber identity module is in an idle state at a time that the first determination is made; and
in response to the first determination being that the second subscriber identity module is in the active state, facilitating, by the network equipment, transmission of a paging request received by the second subscriber identity module, wherein the paging request is designated for the first subscriber identity module.

2. The method of claim 1 , further comprising: initiating, by the network equipment, a paging procedure as part of facilitating the transmission of the paging request; and providing one or more bits in the paging request to signal the paging request is for a voice call or an SMS message.

3. The method of claim 1 , wherein the paging request is transmitted during a voice communication session being provided via the second subscriber identity module, wherein the network equipment is associated with a first network, and wherein the determining whether the second subscriber identity module is in the active state comprises determining whether the second subscriber identity module is in the active state with respect to a second network.

4. The method of claim 1 , wherein facilitating the transmission of the paging request comprises causing the paging request to be transmitted to network node equipment that is communicatively connected to the user equipment.

5. The method of claim 1 , wherein the network equipment is associated with a first network, and wherein facilitating the transmission of the paging request comprises causing the paging request to be transmitted to network equipment associated with a second network.

6. The method of claim 1 , wherein the first subscriber identity module comprises first subscriber identity information representative of a first subscriber identity and the second subscriber identity module comprises second subscriber identity information representative of a second subscriber identity.

7. The method of claim 1 , further comprising sending, to the user equipment by the network equipment, an indication that the paging request was initiated.

8. Network equipment, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining that a second subscriber identity module is communicatively connected to a network node resulting in a first determination, wherein a user equipment comprises the second subscriber identity module and a first subscriber identity module, wherein the first subscriber identity module is in an idle state at a time that the first determination is made; and
in response to the first determination being that the second subscriber identity module is communicatively connected to the network node, transmitting an alert to the second subscriber identity module, wherein the alert indicates a paging message addressed to and designated for the first subscriber identity module has been received by the second subscriber identity module.

9. The network equipment of claim 8 , wherein the determining that the second subscriber identity module is communicatively connected to the network node is responsive to receiving the paging message.

10. The network equipment of claim 8 , wherein the determining that the second subscriber identity module is communicatively connected to the network node comprises determining that a communication link between the second subscriber identity module and the network node is active.

11. The network equipment of claim 8 , wherein transmitting the alert to the second subscriber identity module comprises transmitting the alert via a wired backhaul connection.

12. The network equipment of claim 8 , wherein transmitting the alert to the second subscriber identity module comprises transmitting the alert from first network equipment that is part of a first network to second network equipment that is part of a second network.

13. The network equipment of claim 8 , wherein the first subscriber identity module is unable to communicate directly with the second subscriber identity module.

14. The network equipment of claim 8 , wherein the operations further comprise transmitting to the user equipment an indication that the paging message was received.

15. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
determining whether a mobile device, comprising different subscriber identity modules comprising a first subscriber identity module and a second subscriber identity module, is actively engaged in communication associated with the second subscriber identity module resulting in a first determination, wherein the first subscriber identity module is in an idle state at a time that the first determination is made; and
in response to the first determination indicating that the mobile device is actively engaged in the communication associated with the second subscriber identity module, causing a message to be transmitted to and received by the second subscriber identity module of the mobile device, wherein the message indicates a paging request is addressed to and designated for the first subscriber identity module.

16. The non-transitory machine-readable medium of claim 15 , further comprising initiating a paging procedure comprising delivery of the paging request to the mobile device.

17. The non-transitory machine-readable medium of claim 15 , wherein determining whether the mobile device is actively engaged in the communication associated with the second subscriber identity module comprises determining whether the second subscriber identity module is in an active state.

18. The non-transitory machine-readable medium of claim 15 , wherein causing the message to be transmitted to the mobile device comprises causing the message to be transmitted via network node equipment.

19. The non-transitory machine-readable medium of claim 15 , wherein the operations are performed by first network equipment associated with a first network, and wherein causing the message to be transmitted to the mobile device comprises causing the message to be transmitted via second network equipment associated with a second network.

20. The non-transitory machine-readable medium of claim 19 , wherein causing the message to be transmitted via the second network equipment comprises requesting the second network equipment to transmit the message to the mobile device.
