Abstract

A system, method, and computer readable medium for processing a call setup in a network system are provided. A femtocell system receives a call origination from a user equipment located within a service area of the femtocell system and performs a service connection with the user equipment. The femtocell system creates a connection for an Internet Protocol Multimedia Subsystem core network, transmits an INVITE message to a called telephone device via the Internet Protocol Multimedia Subsystem, and completes the call setup between the user equipment and the called telephone device.

Claims

1. A method of processing a call setup in a network system, comprising:

receiving, by a femtocell system, a call origination from a user equipment performing a calling operation to a called telephone device, the user equipment located within a service area of the femtocell system;

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;

receiving an acknowledgment from the user equipment in receipt of the transmitted channel assignment;

performing, by the femtocell system, a service connection with the user equipment;

creating, by the femtocell system, a connection for an Internet Protocol Multimedia Subsystem core network;

transmitting an INVITE message to the called telephone device via the Internet Protocol Multimedia Subsystem;

receiving a ringing indication at the femtocell system from the Internet Protocol Multimedia Subsystem core network;

transmitting an alert to the user equipment from the femtocell system responsive to receiving the ringing indication from the Internet Protocol Multimedia Subsystem core network; and

completing the 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 receiving, by SIA of the femtocell system from the Internet Protocol Multimedia Subsystem core network, 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 for processing a call setup in a network system, the computer-readable medium comprising instructions that:

receive a call origination from a user equipment performing a calling operation to a called device, the user equipment located within a service area of a femtocell system;

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 the femtocell system;

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

receive an acknowledgment from the user equipment in receipt of the transmitted channel assignment;

perform a service connection with the user equipment including transmitting a configuration management service request to a Session Initiation Protocol to Internet Operating System adapter of the femtocell system;

create a connection for an Internet Protocol Multimedia Subsystem core network;

transmit an INVITE message to the called telephone device via the Internet Protocol Multimedia Subsystem;

receive a ringing indication at the femtocell system from the Internet Protocol Multimedia Subsystem core network;

transmit an alert to the user equipment from the femtocell system responsive to receiving the ringing indication from the Internet Protocol Multimedia Subsystem core network; and

complete the 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 receive from the Internet Protocol Multimedia Subsystem core network a ringing indication.

12. The non-transitory computer-readable storage medium of claim 11, 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 12, further comprising instructions that transmit a modify connection message to a transcoder of the femtocell system.

14. A system configured for call processing in a network 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, the user equipment located within a service area of a femtocell system,

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,

receive an acknowledgment from the user equipment in receipt of the transmitted channel assignment,

perform a service connection with the user equipment including transmitting a configuration management service request to the SIA,

create a connection for an Internet Protocol Multimedia Subsystem,

transmit an INVITE message to the called telephone device via the Internet Protocol Multimedia Subsystem core network,

receive a ringing indication at the femtocell system from the Internet Protocol Multimedia Subsystem core network,

transmit an alert to the user equipment from the femtocell system responsive to receiving the ringing indication from the Internet Protocol Multimedia Subsystem core network, 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 16, wherein a ringback tone is transmitted from the transcoder to the base transceiver station.
