Abstract

A system, method, and computer readable medium for transmit protection in a femtocell system are provided. A multi-stage transmit protection routine prohibits radio transmissions for unregistered femtocell systems and transmissions from femtocell systems in unauthorized areas. A femtocell system may request transmission authorization from a base station manager. The base station manager may provide an authorization failure if the femtocell system is not registered or if the source address of the femtocell system is not within a predefined distance of a registered location of the femtocell system. If the femtocell is provided a transmission authorization, the femtocell system may obtain a GPS location from a user equipment and provide the GPS location to the base station manager which evaluates the location. The base station manager may provide an authorization failure if the GPS location is not within a predefined distance of the registered location of the femtocell system.

Claims

1. A method, comprising:

receiving a transmission authorization request from a femtocell to a base station manager, where the request includes a network address of the femtocell and where the femtocell is connected to a cellular network to enable call services to be provided to a mobile device in radio communication with the femtocell;

determining, by the base station manager, a first geographic location based on the network address;

determining whether the first geographic location is within a predefined distance of a registered location;

receiving, by the femtocell, a user equipment registration;

receiving, by the femtocell, a global positioning system location from the user equipment;

transmitting, by the femtocell, the global positioning system location to the base station manager;

determining whether the global positioning system location is within a predefined distance of the registered location; and

transmitting, by the base station manager, a secondary transmission authorization to the femtocell in response to determining the global positioning system location is within the predefined distance of the registered location.

2. The method of claim 1, where determining whether the first geographic location is within a predefined distance comprises determining the first geographic location is not within the predefined distance, the method further comprising transmitting a transmission authorization failure notification to the femtocell.

3. The method of claim 1, where determining whether the first geographic location is within a predefined distance comprises determining the first geographic location is within the predefined distance, the method further comprising transmitting a transmission authorization to the femtocell.

4. The method of claim 3, further comprising:

receiving, by the femtocell, the transmission authorization; and

engaging in radio transmissions by the femtocell.

5. The method of claim 3, further comprising transmitting configuration data to the femtocell.

6. The method of claim 1, wherein the femtocell comprises a base transceiver station and a base station controller.

7. The method of claim 1, further comprising comparing the first geographic location with a registered location of the femtocell.

8. The method of claim 1, further comprising comparing, by the base station manager, the global positioning system location with the registered location.

9. The method of claim 1, further comprising transmitting, by the base station manager, a secondary transmission authorization failure notification to the femtocell in response to determining the global positioning system location is not within the predefined distance of the registered location.

10. A non-transitory computer-readable medium having computer-executable instructions for execution by a processing system, the computer-executable instructions that:

receive a transmission authorization request from a femtocell, where the request includes a network address of the femtocell and where the femtocell is connected to a cellular network to enable call services to be provided to a mobile device in radio communication with the femtocell;

determine a first geographic location based on the network address;

retrieve registration information of the femtocell that includes a registered location of the femtocell;

determine whether the first geographic location is within a predefined distance of the registered location;

receive a global positioning system location of a user equipment;

determine whether the global positioning system location is within a predefined distance of the registered location; and

transmit a secondary transmission authorization to the femtocell in response to determining the global positioning system location is within the predefined distance of the registered location.

11. The non-transitory computer-readable medium of claim 10, wherein the instructions that determine whether the first geographic location is within a predefined distance comprise instructions that determine the first geographic location is not within the predefined distance, the computer-readable medium further comprising instructions that transmit a transmission authorization failure notification to the femtocell.

12. The non-transitory computer-readable medium of claim 10, wherein the instructions that determine whether the first geographic location is within a predefined distance comprise instructions that determine the first geographic location is within the predefined distance, the computer-readable medium further comprising instructions that transmit a transmission authorization to the femtocell.

13. The non-transitory computer-readable medium of claim 12, further comprising instructions that receive, by the femtocell, the transmission authorization.

14. The non-transitory computer-readable medium of claim 12, further comprising instructions that engage in radio transmissions by the femtocell.

15. The non-transitory computer-readable medium of claim 12, further comprising instructions that transmit configuration data to the femtocell.

16. The non-transitory computer-readable medium of claim 10, further comprising instructions that compare the first geographic location with the registered location.

17. The non-transitory computer-readable medium of claim 10, further comprising instructions that compare the global positioning system location with the registered location.

18. The non-transitory computer-readable medium of claim 10, further comprising instructions that transmit, by the base station manager, a secondary transmission authorization failure notification to the femtocell in response to determining the global positioning system location is not within the predefined distance of the registered location.

19. A system, comprising:

a packet-switched network;

a base station manager server communicatively coupled with the packet-switched network that maintains registration information of at least one femtocell, wherein the registration information includes a registered location of the at least one femtocell; and

a femtocell communicatively coupled with the packet-switched network that transmits a transmission authorization request to the base station manager server that includes a network address of the femtocell and is able to provide call services to a mobile device in radio communication with the femtocell, wherein the femtocell is connected to a cellular network via an IP network to enable call services to be provided to a mobile device in radio communication with the femtocell, wherein the base station manger server determines a first geographic location based on the network address, retrieves registration information of the femtocell that includes a registered location of the femtocell, determines whether the first geographic location is within a predefined distance of the registered location, and transmits one of a transmission authorization and a transmission authorization failure to the femtocell,

wherein the femtocell receives a user equipment registration, receives a global positioning system location from the user equipment and transmits the global positioning system location to the base station manager;

wherein the base station manager determines whether the global positioning system location is within a predefined distance of the registered location, and transmits one of a secondary transmission authorization and a secondary transmission authorization failure to the femtocell.

20. The system of claim 19, wherein the femtocell comprises a base transceiver station and a base station controller.
