Abstract

A system, method, and computer readable medium that facilitates delivery of mobile-terminated short message service messages to a mobile station attached with a femtocell system are provided. A convergence server deployed in a core network receives a short message for short message service delivery to a mobile station attached with a femtocell system. If there is no active traffic channel with the mobile station, or if the short message is to be delivered to the mobile station via a paging channel, the femtocell system triggers an authentication process. The convergence server constructs a short message service delivery request message, transmits the short message service delivery request message to the femtocell system, and receives one of an acknowledgement and a negative acknowledgment regarding delivery of the short message to the mobile station. The convergence server thereafter notifies the message center of the acknowledgment or negative acknowledgement received thereby.

Claims

1. A method of facilitating mobile-terminated short message delivery to a mobile station attached with a femtocell system, comprising:

receiving, by a convergence server deployed in a core network, a short message for short message service delivery to a mobile station attached with a femtocell system;

constructing, by the convergence server, a short message service delivery request message after evaluation of mobile station short message service terminating restrictions;

transmitting, by the convergence server, the short message service delivery request message to the femtocell system;

receiving, by the convergence server, one of an acknowledgement and a negative acknowledgment regarding delivery of the short message to the mobile station; and

notifying, by the convergence server, a mobile core network of the acknowledgment or negative acknowledgement received by the convergence server; and

authenticating, by the femtocell system, validation of credentials of the mobile station when validation is required, wherein authenticating by the femtocell comprises;

determining if there is an active channel to the mobile station;

where there is no active channel to the mobile station;

sending a paging request from the femtocell to the mobile station;

receiving a paging response from the mobile station comprising authentication parameters; and

forwarding, by the femtocell, the paging response to the convergence server.

2. The method of claim 1, further comprising:

engaging, by the convergence server, the mobile core network in an authentication process for the mobile station.

3. The method of claim 2, wherein the engaging of the mobile core network in the authentication process comprises engaging a message center of the mobile core network in the authentication process.

4. The method of claim 1, further comprising:

receiving, by the convergence server, a paging authentication request message from the femtocell system.

5. The method of claim 4, further comprising:

transmitting, by the convergence server, an authentication result received from the mobile core network to the femtocell system.

6. The method of claim 1, further comprising:

triggering, by the femtocell system, an authentication process responsive to determining no traffic channel currently exists between the femtocell system and the mobile station and that the short message is to be delivered via a traffic channel.

7. The method of claim 1, further comprising:

transmitting, by the femtocell system, the short message to the mobile station by one of a traffic channel and a paging channel.

8. The method of claim 1, wherein the receiving of the short message is performed responsive to the convergence server notifying a message center that the mobile station has become available for delivery of the short message.

9. 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 mobile-terminated short message delivery to a mobile station attached with a femtocell system, that when executed, cause the processing system to:

notify, by a convergence server deployed in a core network, a message center that a mobile station attached with a femtocell system has become available for delivery of a short message;

receive, by the convergence server, the short message for short message service delivery to the mobile station;

construct, by the convergence server, a short message service delivery request message after evaluation of mobile station short message service terminating restrictions;

transmit, by the convergence server, the short message service delivery request message to the femtocell system;

receive, by the convergence server, one of an acknowledgement and a negative acknowledgment regarding delivery of the short message to the mobile station; and

notify, by the convergence server, a mobile core network of the acknowledgment or negative acknowledgement received by the convergence server, wherein

the femtocell system authenticates validation of credentials of the mobile station when validation is required, wherein authenticating by the femtocell comprises;

determining if there is an active channel to the mobile station;

where there is no active channel to the mobile station;

sending a paging request from the femtocell to the mobile station;

receiving a paging response from the mobile station comprising authentication parameters; and

forwarding, by the femtocell, the paging response to the convergence server.

10. The non-transitory computer-readable medium of claim 9, further comprising instructions that, when executed by the processing system, cause the processing system to engage, by the convergence server, the mobile core network in an authentication process for the mobile station.

11. The non-transitory computer-readable medium of claim 10, further comprising instructions that, when executed by the processing system, cause the processing system to engage the message center in the authentication process.

12. The non-transitory computer-readable medium of claim 9, further comprising instructions that, when executed by the processing system, cause the processing system to receive, by the convergence server, a paging authentication request message from the femtocell system.

13. The non-transitory computer-readable medium of claim 12, further comprising instructions that, when executed by the processing system, cause the processing system to transmit, by the convergence server, an authentication result received from the mobile core network to the femtocell system.

14. The non-transitory computer-readable medium of claim 9, further comprising instructions that, when executed by the processing system, cause the processing system to trigger, by the femtocell system, an authentication process responsive to determining no traffic channel currently exists between the femtocell system and the mobile station and that the short message is to be delivered via a traffic channel.

15. The non-transitory computer-readable medium of claim 9, further comprising instructions that, when executed by the processing system, cause the processing system to transmit, by the femtocell system, the short message to the mobile station by one of a traffic channel and a paging channel.

16. A network system that facilitates mobile-terminated short message delivery to a mobile station attached with a femtocell system, comprising:

a core network that includes a convergence server;

a mobile core network that includes a message center; and

an Internet Protocol-based femtocell system that provides a radio access point for a mobile station, wherein the convergence server is configured to;
