System, method, and computer-readable medium for processing call originations by a femtocell system

1. A method, comprising:

receiving, by a femtocell system, a call origination from a user equipment performing a calling operation to a called telephone device;

generating a configuration management service request message and transmitting the configuration management service request message to a session initiation protocol to Internet operating system adapter (SIA);

responsive to receiving the configuration management service request message, generating a channel assignment request by the SIA and transmitting the channel assignment request to the femtocell system;

allocating a channel for the user equipment and transmitting the allocated channel to the user equipment; and

completing a call setup between the user equipment and the called telephone device via the allocated channel.

2. The method of claim 1 , wherein a base transceiver station of the femtocell system is configured to transmit the configuration management service request to the SIA of the femtocell system.

3. The method of claim 2 , wherein the base transceiver station is configured to receive the channel assignment request from the SIA.

4. The method of claim 3 , wherein the base transceiver station is configured to transmit the channel assignment request to the user equipment.

5. The method of claim 1 , further comprising transmitting, by the SIA of the femtocell system, a bearer request to a base transceiver station of the femtocell system.

6. The method of claim 1 , further comprising creating, by the femtocell system, a connection for an Internet Protocol Multimedia Subsystem, and receiving, by the SIA of the femtocell system from the Internet Protocol Multimedia Subsystem, a ringing indication.

7. The method of claim 6 , further comprising transmitting a ringback tone from a transcoder of the femtocell system to a base transceiver station of the femtocell system.

8. The method of claim 7 , further comprising transmitting, by the SIA, a modify connection message to the transcoder.

9. A non-transitory computer-readable storage medium having computer-executable instructions for execution by a processing system, the computer-executable instructions that:

receive a call origination from a user equipment performing a calling operation to a called device;

generate a configuration management service request message and transmit the configuration management service request message to a session initiation protocol to Internet operating system adapter (SIA);

responsive to receiving the configuration management service request message, generate a channel assignment request by the SIA and transmit the channel assignment request to a femtocell system;

allocate a channel for the user equipment and transmit the allocated channel to the user equipment; and

complete a call setup between the user equipment and the called telephone device via the allocated channel.

10. The non-transitory computer-readable storage medium of claim 9 , further comprising instructions that transmit a bearer request to a base transceiver station of the femtocell system.

11. The non-transitory computer-readable storage medium of claim 9 , further comprising instructions that create a connection for an Internet Protocol Multimedia Subsystem and receive from the Internet Protocol Multimedia Subsystem a ringing indication.

12. The non-transitory computer-readable storage medium of claim 9 , further comprising instructions that transmit a ringback tone to a base transceiver station of the femtocell system.

13. The non-transitory computer-readable storage medium of claim 9 , further comprising instructions that transmit a modify connection message to a transcoder of the femtocell system.

14. A system, comprising:

a packet-switched network;

an Internet Protocol Multimedia subsystem communicatively coupled with the packet-switched network; and

a femtocell system communicatively coupled with the packet-switched network, wherein the femtocell system includes a base transceiver station, a transcoder, and a Session Initiation Protocol to Internet Operating System adapter (SIA), wherein the femtocell system is configured to:

receive a call origination from a user equipment configured to perform a calling operation to a called device;

generate a configuration management service request message and transmit the configuration management service request message to a session initiation protocol to the SIA;

responsive to receiving the configuration management service request message, generate a channel assignment request by the SIA and transmit the channel assignment request to the femtocell system;

allocate a channel for the user equipment and transmit the allocated channel to the user equipment; and

complete the call setup between the user equipment and the called telephone device via the allocated channel.

15. The system of claim 14 , wherein the SIA transmits a bearer request to the base transceiver station.

16. The system of claim 14 , wherein the SIA receives a ringing indication from the Internet Protocol Multimedia Subsystem.

17. The system of claim 14 , wherein a ringback tone is transmitted from the transcoder to the base transceiver station.

18. The system of claim 14 , wherein the femtocell system is configured to create a connection for the Internet Protocol Multimedia Subsystem, and receive a ringing indication from the Internet Protocol Multimedia Subsystem.

19. The system of claim 14 , wherein the femtocell system is configured to transmit an alert to the user equipment.

20. The system of claim 19 , wherein the alert is transmitted responsive to receiving the ringing indication from the Internet Protocol Multimedia Subsystem.
