Abstract

Claims (22)

1. A method to control operation of a mobile communication device in a vehicle, comprising:

determining if the vehicle is moving;

if the vehicle is stationary, allowing calls to reach a cell tower by configuring a femtocell base station with a predetermined range to inside the vehicle based on initialization data, wherein the femtocell base station intercepts and forwards the calls to the cell tower;

if the vehicle is moving and the mobile communication device is used, disabling a transmission from the mobile communication device to the cell tower wherein the femtocell base station intercepts and blocks the calls to the cell tower; and

if the vehicle is moving and an emergency phone sequence is dialed, allowing the transmission from the mobile communication device to the cell tower wherein the femtocell base station intercepts and forwards the calls to the cell tower.

2. The method of claim 1 , comprising determining movement using an accelerometer.

3. The method of claim 1 , wherein the emergency phone sequence comprises 911.

4. The method of claim 1 , wherein the receiving of the initialization data further comprises: sending an initialization call to a macrocell base station at the cell tower, wherein mobile communication device sends the initialization call, and wherein the initialization data is calculated from based on transmission characteristics of the initialization call.

5. The method of claim 1 , comprising validating the mobile communication device.

6. The method of claim 1 , comprising identifying the mobile communication device with an International Mobile Subscriber Identify (IMSI).

7. The method of claim 6 , wherein the IMSI identifying further comprises: comparing a user equipment identifier to an access control list, wherein when the access control list includes an entry that matches the user equipment identifier, and authorizing the mobile communication device.

8. The method of claim 1 , comprising re-routing calls to and from the mobile communications device.

9. The method of claim 8 , wherein re-routing uses a femtocell.

10. The method of claim 9 , wherein the femtocell is based on Orthogonal Frequency-Division Multiple Access technology, comprising adjusting of the femtocell base station transmitting power to control.

11. The method of claim 10 , comprising receiving subcarrier assignments for a macrocell equipment; and decreasing the femtocell base station transmitting power for the subcarrier assignments for the macrocell equipment.

12. A communication system, comprising:

a communication network including a macrocell base station and a femtocell located in a vehicle, the femtocell including a base station;

computer readable code to configure the femtocell base station transmitting power to limit range to inside the vehicle based on initialization data;

code to receive a user equipment identifier from a macrocell equipment in the communication network;

code to validate the user equipment identifier to determine whether the operation of the cell phone is authorized or unauthorized depending on vehicular movement.

13. The system of claim 12 , when the operation of the phone is authorized, the macrocell equipment is granted access to the femtocell base station.

14. The system of claim 12 , when the operation of the cell phone is unauthorized, the femtocell base station transmitting power is reduced based on the user equipment information to allow or disallow usage of mobile devices in the communications network.
