Abstract

A system, method, and computer readable medium that facilitates processing of a mobile-originated voice call for a mobile station attached with a femtocell system are provided. The femtocell system may broadcast a notification that authentication is required for all system access, e.g., via an overhead message train. The femtocell system receives a call origination request from the mobile station and, in turn, issues a service request message to a convergence server deployed in a core network. The convergence server then engages in an authentication procedure with the mobile station'"'"'s mobile core network and returns a global challenge response to the femtocell system. Then convergence server may then determine if the mobile station is to be validated and, if so, may continue call set up for the call origination request.

Claims

1. A method of facilitating processing of a mobile-originated voice call for a mobile station attached with a femtocell system, comprising:

receiving, by the femtocell system, a call origination request from the mobile station;

in response to receiving the call origination request, transmitting, by the femtocell system, authentication data in a service request message to a convergence server deployed in a core network;

receiving, by the femtocell system, a global challenge response from the convergence server in response to sending the authentication data, wherein the global challenge response includes an authentication token that is stored at the femtocell for subsequent transmission from the femtocell back to the convergence server; and

receiving, by the femtocell system, a determination of validation for the voice call from the convergence server.

2. The method of claim 1, further comprising notifying, by the femtocell system, the mobile station that authentication is required by the mobile station for system access.

3. The method of claim 1, further comprising initiating, by the convergence server, an authentication procedure with a mobile core network responsive to receipt of the service request message from the femtocell system.

4. The method of claim 1, further comprising transmitting, by the femtocell system, a Session Initiation Protocol Invite message to the convergence server that includes the authentication token.

5. The method of claim 1, further comprising establishing, by the femtocell system, a voice channel with the mobile station responsive to receipt of the global challenge response.

6. The method of claim 1, wherein the call origination request includes an origination authentication result generated by the mobile station.

7. The method of claim 6, wherein the origination authentication result is generated by the mobile station using a random number provided thereto by the femtocell system, an electronic serial number of the mobile station, dialed digits of the call origination request, and a shared secret data key stored by the mobile station.

9. The non-transitory computer-readable medium of claim 7, further comprising instructions that, when executed by the processing system, cause the processing system to initiate, by the convergence server, an authentication procedure with a mobile core network responsive to receipt of the service request message from the femtocell system.

8. A non-transitory computer-readable medium having computer-executable instructions tangibly embodied thereon for execution by a processing system, the computer-executable instructions for facilitating processing of a mobile-originated voice call for a mobile station attached with a femtocell system that, when executed, cause the processing system to:

notify, by the femtocell system, the mobile station that authentication is required by the mobile station for system access;

receive, by the femtocell system, a call origination request from the mobile station;

in response to receiving the call origination request, transmit, by the femtocell system, authentication data in a service request message to a convergence server deployed in a core network;

receive, by the femtocell system, a global challenge response from the convergence server in response to sending the authentication data, wherein the global challenge response includes an authentication token that is stored at the femtocell for subsequent transmission from the femtocell back to the convergence server; and

receive, by the femtocell system, a determination of validation for the voice call from the convergence server.

10. The non-transitory computer-readable medium of claim 8, further comprising instructions that, when executed by the processing system, cause the processing system to transmit, by the femtocell system, a Session Initiation Protocol Invite message to the convergence server that includes the authentication token.

11. The non-transitory computer-readable medium of claim 8, further comprising instructions that, when executed by the processing system, cause the processing system to establish, by the femtocell system, a voice channel with the mobile station responsive to receipt of the global challenge response.

12. The non-transitory computer-readable medium of claim 8, wherein the call origination request includes an origination authentication result generated by the mobile station.

13. The non-transitory computer-readable medium of claim 12, wherein the origination authentication result is generated by the mobile station using a random number provided thereto by the femtocell system, an electronic serial number of the mobile station, dialed digits of the call origination request, and a shared secret data key stored by the mobile station.

14. A network system that facilitates processing of a mobile-originated voice call for a mobile station attached with a femtocell system, comprising:

a core network that includes a convergence server;

a mobile core network that includes an authentication center and a Home Location Register; and

an Internet Protocol-based femtocell system that provides a radio access point for a mobile station, wherein the femtocell system receives a call origination request from the mobile station, in response to receiving the call origination request transmits authentication data in a service request message to the convergence server, receives a global challenge response from the convergence server in response to sending the authentication data, wherein the global challenge response includes an authentication token that is stored at the femtocell for subsequent transmission from the femtocell back to the convergence server, and receives a determination of validation for the voice call from the convergence server.

15. The system of claim 14, wherein the femtocell system notifies the mobile station that authentication is required by the mobile station for system access by broadcast of an overhead message train.

16. The system of claim 14, wherein the core network that includes the convergence server comprises one of an Internet Protocol core network and an Internet Multimedia Subsystem core network.

17. The system of claim 14, wherein the convergence server initiates an authentication procedure with the authentication center and the Home Location Register responsive to receipt of the service request message from the femtocell system.
