System, method, and computer-readable medium for mobile terminated call processing by a femtocell system
View Patent ↗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 for a call to be terminated with a user equipment serviced by the femtocell system from a core network, transmits a page message to the user equipment, performs a service connection with the user equipment, creates a connection for the core network, and completes the call setup with the user equipment.
1. A method, comprising:
receiving, by a femtocell system, a call origination for a call to be terminated with a user equipment serviced by the femtocell system from a core network;
transmitting, by a Session Initiation Protocol to Internet Operating System adapter of the femtocell system, a create connection message to a transcoder of the femtocell system; and
performing, by the femtocell system, a service connection with the user equipment.
2. The method of claim 1 , wherein creating a connection for the core network comprises creating a connection for an Internet Protocol Multimedia Subsystem core network.
3. The method of claim 1 , comprising creating, by the femtocell system, a connection for the core network.
4. The method of claim 1 , comprising opening at least one real time transport protocol port at the transcoder in response to receiving the create connection message.
5. The method of claim 4 , wherein opening at least one real time transport protocol port further comprises specifying a service mode as receive only.
6. The method of claim 1 , comprising:
transmitting, by a base transceiver station of the femtocell system, a channel assignment to the user equipment; and
receiving, by the base transceiver station, a service connection completion message from the user equipment.
7. The method of claim 6 , comprising transmitting, by the femtocell system, a ringing indication to the core network in response to receipt of the service connect completion message.
8. The method of claim 7 , comprising modifying a connection service mode of a transcoder of the femtocell system to a send and receive mode in response to receipt of an acknowledgement to the ringing indication received from the core network.
9. A non-transitory computer-readable medium having computer-executable instructions for execution by a processing system, the computer-readable medium comprising instructions that:
receive, by a femtocell system, a call origination for a call to be terminated with a user equipment serviced by the femtocell system from a core network;
transmit, by a Session Initiation Protocol to Internet Operating System adapter of the femtocell system, a create connection message to a transcoder of the femtocell system; and
perform, by the femtocell system, a service connection with the user equipment.
10. The non-transitory computer-readable medium of claim 9 , comprising instructions that create, by the femtocell system, at least one of:
a connection for the core network; and
a connection for an Internet Protocol Multimedia Subsystem core network.
11. The non-transitory computer-readable medium of claim 9 , further comprising instructions that open at least one real time transport protocol port at the transcoder in response to receiving the create connection message.
12. The non-transitory computer-readable medium of claim 11 , wherein the instructions that open at least one real time transport protocol port further comprise instructions that specify a service mode as receive only.
13. The non-transitory computer-readable medium of claim 9 , further comprising instructions that:
transmit, by a base transceiver station of the femtocell system, a channel assignment to the user equipment; and
receive, by the base transceiver station, a service connection completion message from the user equipment.
14. The non-transitory computer-readable medium of claim 13 , further comprising instructions that transmit a ringing indication to the core network in response to receipt of the service connect completion message.
15. The non-transitory computer-readable medium of claim 14 , further comprising instructions that modify a connection service mode of a transcoder of the femtocell system to a send and receive mode in response to receipt of an acknowledgement to the ringing indication received from the core network.
16. 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, wherein the femtocell system receives a call origination for a call to be terminated with a user equipment serviced by the femtocell system from the Internet Protocol Multimedia subsystem, wherein the Session Initiation Protocol to Internet Operating System adapter transmits a create connection message to the transcoder and the transcoder opens at least one real time transport protocol port in response thereto, and wherein the femtocell system performs a service connection with the user equipment.
17. The system of claim 16 , wherein the transcoder specifies a service mode as receive only when the at least one real time transport protocol port is opened.
18. The system of claim 16 , wherein the base transceiver station transmits a channel assignment to the user equipment and receives a service connection completion message from the user equipment.
19. The system of claim 18 , wherein the femtocell system transmits a ringing indication to the Internet Protocol Multimedia subsystem in response to receiving the service connect completion message.
20. The system of claim 19 , wherein the transcoder modifies a connection service mode to a send and receive mode in response to receipt of an acknowledgement to the ringing indication received from the Internet Protocol Multimedia subsystem.
