Abstract

A system, method, and computer readable medium for terminating a call in a network system are provided. A femtocell system receives a notification to terminate a call that includes a user equipment serviced by the femtocell system. The femtocell system conveys a clear command to a base transceiver station of the femtocell system, transmits a release message to the user equipment, receives a clear completion message, and deletes a connection allocated for the call.

Claims

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

receiving, by an integral femtocell unit comprising a base transceiver station, a transcoder and a Session Initiation Protocol to Internet Operating System adapter, the base transceiver station, transcoder and Session Initiation Protocol to Internet Operating System adapter all housed within a unitary housing, a notification to terminate the call, wherein the call includes a user equipment serviced by the femtocell unit;

conveying, by the femtocell unit, a clear command to the base transceiver station of the femtocell unit;

transmitting, by the femtocell unit, a release message to the user equipment;

receiving, by the femtocell unit, a clear completion message; and

deleting a connection within the femtocell unit allocated for the call;

wherein deleting a connection allocated for the call comprises transmitting, by the Session Initiation Protocol to Internet Operating System adapter, a delete connection message to the transcoder of the femtocell unit.

2. The method of claim 1, wherein receiving a notification to terminate the call comprises receiving a mobile release message from the user equipment.

3. The method of claim 2, wherein receiving a mobile release message comprises receiving the mobile release message by the base transceiver station.

4. The method of claim 1, wherein receiving a notification to terminate the call comprises receiving a termination request from an Internet Protocol Multimedia subsystem.

5. The method of claim 4, wherein receiving the termination request comprises receiving a Session Initiation Protocol BYE message.

6. The method of claim 1, further comprising releasing, by the transcoder, at least one port allocated for the call.

7. The method of claim 1, wherein receiving a notification to terminate the call comprises receiving a mobile release message from the user equipment, the method further comprising:

transmitting, by the base transceiver station, a clear request to a Session Initiation Protocol to Internet Operating System adapter of the femtocell unit; and

transmitting, by the Session Initiation Protocol to Internet Operating System adapter, a Session Initiation Protocol BYE message to an Internet Protocol Multimedia subsystem.

8. A non-transitory computer-readable medium having computer-executable instructions for execution by a processing system of a femtocell unit comprising a base transceiver station and a transcoder, the computer-executable instructions for terminating a call in a network system, the base transceiver station, transcoder and Session Initiation Protocol to Internet Operating System adapter all housed within a unitary housing, the computer-readable medium comprising instructions that:

receive a notification to terminate the call, wherein the call includes a user equipment serviced by the femtocell system;

convey a clear command to the base transceiver station of the femtocell unit;

transmit a release message to the user equipment;

receive a clear completion message;

delete a connection allocated for the call; and

release a port allocated for the call at the transcoder of the femtocell unit.

9. The non-transitory computer-readable medium of claim 8, wherein the instructions that receive a notification to terminate the call comprise instructions that receive a mobile release message from the user equipment.

10. The non-transitory computer-readable medium of claim 9, wherein the instructions that receive a mobile release message comprise instructions that receive the mobile release message by the base transceiver station.

11. The non-transitory computer-readable medium of claim 8, wherein the instructions that receive a notification to terminate the call comprise instructions that receive a termination request from an Internet Protocol Multimedia subsystem.

12. The non-transitory computer-readable medium of claim 11, wherein the instructions that receive the termination request comprise instructions that receive a Session Initiation Protocol BYE message.

13. The non-transitory computer-readable medium of claim 8, wherein the instructions that delete a connection allocated for the call comprise instructions that transmit a delete connection message to the transcoder of the femtocell unit.

14. The non-transitory computer-readable medium of claim 8, wherein the instructions that receive a notification to terminate the call comprise instructions that receive a mobile release message from the user equipment, the computer-readable medium further comprising instructions that:

transmit a clear request to a Session Initiation Protocol to Internet Operating System adapter of the femtocell unit; and

transmit a Session Initiation Protocol BYE message to an Internet Protocol Multimedia subsystem.

15. A system configured for terminating a call in a network system, comprising:

a packet-switched network;

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

a femtocell unit communicatively coupled with the packet-switched network, wherein the femtocell unit includes a base transceiver station, a transcoder, and a Session Initiation Protocol to Internet Operating System adapter, the base transceiver station, transcoder and Session Initiation Protocol to Internet Operating System adapter all housed within a unitary housing, wherein the femtocell system receives a notification to terminate the call, wherein the call includes a user equipment serviced by the femtocell unit, wherein the Session Initiation Protocol to Internet Operating System adapter conveys a clear command to the base transceiver station, the base transceiver station transmits a release message to the user equipment and a clear completion message to the Session Initiation Protocol to Internet Operating System adapter, and wherein the transcoder deletes a connection allocated for the call and releases a port allocated for the call.

16. The system of claim 15, wherein the notification to terminate the call comprises a mobile release message transmitted from the user equipment and is received by the base transceiver station.

17. The system of claim 15, wherein the notification to terminate the call comprises a termination request transmitted from the Internet Protocol Multimedia subsystem.

18. The system of claim 15, wherein the termination request comprises a Session Initiation Protocol BYE message.

19. The system of claim 15, wherein the base transceiver station transmits a clear request to the Session Initiation Protocol to Internet Operating System adapter, and wherein the Session Initiation Protocol to Internet Operating System adapter transmits a Session Initiation Protocol BYE message to the Internet Protocol Multimedia subsystem.
